This may be partly due to higher rates of hospital admission and high rates of prevalence within care home populations virus mp3 discount generic fucidin uk. Sodium fusidate or rifampicin may be used in combination with vancomycin or used together for soft tissue infections that fail to respond antibiotic or antifungal buy fucidin 10 gm low cost. Tetracycline or clindamycin may be appropriate for some soft tissue infections and bronchiectasis antibiotics used for urinary tract infections fucidin 10 gm overnight delivery. Urinary tract infections may respond to tetracycline antimicrobial stewardship buy fucidin 10gm free shipping, trimethoprim or nitrofurantoin virus 65 cheap 10gm fucidin amex. It can also affect cranial nerve nuclei to give a clinical picture of progressive bulbar palsy infection zombie games order fucidin mastercard. In this situation wasting and fasciculations may be seen in the facial muscles and tongue. Half of patients die within three years,71 but 25% are alive at five years, and 10% live beyond 10 years. A worse prognosis is suggested by an older age and presentation with bulbar features. Patients presenting after the age of 70 years are more likely to have initial bulbar signs (perhaps 50% of cases). Riluzole has been associated with decreased death at 12 months, but no benefit on muscle strength. Reflexes are present but may be diminished (whereas they may be lost in polyneuropathies), sensation is intact. Discussion here is limited to polymyositis, giant cell arteritis and statin-induced myopathy. Polymyositis Polymyositis causes a slowly progressive, symmetrical, proximal weakness. There can also be cardiopulmonary involvement causing pneumonitis, conduction defects, pericarditis, or myocarditis. Dermatomyositis causes a rash in addition to muscular symptoms and has a more frequent association with malignancy. It can also cause a heliotrope periorbital rash, or less commonly macular erythema over the anterior chest or shoulders. It may be associated with malignancy, especially in the elderly, and most commonly with ovarian, gastrointestinal, lung, or breast cancer. These later two conditions are similar in that they occur after age 50, respond rapidly to steroids, and have a poorly understood aetiology (see Table 20. Fever, malaise, night sweats, and weight loss are present in around a third of people. There may be anaemia of chronic disease (two-thirds of people) and abnormal liver enzymes (a third of people). The steroids can usually be slowly reduced and withdrawn over a period of several months. Other symptoms include jaw claudication (50% of cases), scalp tenderness (50%), and visual loss (20%). The formation of a thoracic aortic aneurysm (possibly with dissection) is a rare late feature. A temporal artery biopsy (ideally before steroids, but may be positive up to two weeks after their commencement) may reveal a characteristic pattern of vasculitis. The artery may only show segmental involvement, so a 2 cm length sample is required. Treatment is with steroids (typically prednisolone at a dose of 40 to 60 mg per day). They may cause a range of presentations, from being asymptomatic to developing rhabdomyolysis. The incidence of rhabdomyolysis is around four per 100 000 per year on atorvastatin, simvastatin or pravastatin. Typical symptoms include myalgia, muscle tenderness, weakness, nocturnal cramps, and tendon pain. The duration of therapy prior to developing symptoms has a mean of six months (range one week to four years). The symptoms persist for a mean two months (one week to four months) following discontinuation of the drug. Statins are unlikely to be causative if the patient has been on them for several years. Other drugs that may increase the risk include those that are inhibitors or substrates of cytochrome P450 pathway. Those aged over 90 years are five times more likely to develop pneumonia and twice as likely to die from it compared to people aged 65 to 69 years (mortality 7. They are less likely to report cough, shortness of breath or pleuritic chest pain, but are more likely to have an elevated respiratory rate compared to younger people. Pseudomonas aeruginosa may be a more likely cause in those undergoing tube feeding. In many patients the underlying organism is never identified as frail elderly patients are often unable to provide suitable sputum samples for testing. Pneumococcal polysaccharide vaccine (available as 7-valent and 23-valent versions) has been developed for the prevention of pneumonia caused by S. A Japanese study found a 23-valent vaccine, compared to placebo, reduced rates of pneumococcal pneumonia (2. Repeat injections are recommended five-yearly for those with splenectomy or chronic kidney disease. Influenza vaccination may reduce the risk of secondary bacterial pneumonia (see p. Aspiration pneumonia Aspiration pneumonia or pneumonitis occurs following either oropharyngeal or gastric contents entering the lower respiratory tract. These two entities may be hard to distinguish clinically as they may both cause similar clinical symptoms and signs, blood test results and chest X-ray appearances. Aspiration pneumonitis is an inflammation of the lungs in response to the inhalation of acidic gastric contents. Presenting symptoms may range from acute respiratory distress syndrome and shock to mild cough with low oxygen saturation. The symptoms usually commence soon after the aspiration event but some are asymptomatic. In this situation a sterile pneumonitis is likely and antibiotics are probably unnecessary unless symptoms last beyond 24 hours. Silent aspiration occurs even in healthy older adults more commonly than in younger individuals. This is more common in people with an impaired swallow, or cough reflex, or those on medications that are either sedating or reduce saliva production. If it occurred when lying down these will be the posterior segments of the upper lobes or apical segments of the lower lobes, if sitting up then the basal segments of the lower lobes are most likely to be affected. Bacteria isolated from early studies suggested a major role for anaerobic organisms. However, anaerobes were often found in combination with gram-negative organisms, and most infections responded well to initial nonanaerobic antibiotic coverage. Therefore, the choice of antibiotic will partly depend on the location of its onset. One study of 100 older patients (median age 82 years), mainly residing in nursing homes, found that clindamycin was as effective as combinations of a penicillin and a beta-lactamase inhibitor for treating aspiration pneumonia. Improving dental hygiene in susceptible individuals may also have a beneficial effect. They develop in areas where pressure on the skin overlying a bony prominence restricts capillary blood flow, resulting in tissue hypoxia then necrosis and breakdown. This process is worsened by a reduction in the natural padding provided by subcutaneous fat associated with poor nutrition and other factors such as moisture levels (including incontinence), shear and friction forces. Elderly patients are at an increased risk, especially following hip fracture or spinal injury. The pathogenesis has been subdivided into four stages but progression of the lesions does not always follow this linear pattern. Assessment the site and stage of pressure damage should be recorded for all patients entering a geriatric unit. This is probably only clinically significant when there is evidence of infection such as surrounding erythema, the characteristic odour of anaerobic organisms (usually Bacteroides species) or suspected osteomyelitis. Prevention Various screening tools have been developed to try to identify those patients most at risk and therefore try to target intervention strategies. People at high risk often have reduced mobility, nutritional deficiency, inability to reposition themselves and cognitive impairment. Ulcer formation has been known to occur after time intervals as short as two hours. The aim is at least four-hourly repositioning for those at high risk, and at least every six hours for those judged at risk. The frequency of dressing changes can vary according to the product used; at each change the ongoing suitability of that type of dressing should be reassessed. Can also be used to protect body areas at risk of damage Can be used to protect at-risk skin from friction injury. Not suitable when there is moderate to heavy exudate For shallow and minimally exudating ulcers. Can be useful for infected ulcers (while receiving concurrent treatment for infection) For exudative stage 2 or shallow stage 3 ulcers. Can be used on painful ulcers or to protect at-risk skin from shear injury For ulcers that are infected or at high risk of infection Used when there is moderate to heavy exudate. Iodine acts as an antiseptic Hydrogel Alginate Foam Silver-impregnated Cadexomer iodine Vacuum-assisted dressings have also been developed. These create a negative pressure gradient across a suitably sized piece of polyurethane foam fitted into the wound cavity. It is felt that this may reduce wound healing times by the more effective reduction of wound exudates, surrounding oedema and bacterial colonisation. In an unrandomised, retrospective study, the use of larvae for chronic pressure ulcers was associated with more rapid healing than conventional therapy. Larval therapy may be most useful when sharp debridement is contraindicated or if there is associated vascular insufficiency. Debridement is believed to improve wound healing by removing the necrotic tissue that has harmful effects on the wound. It has the added benefits of potentially unmasking underlying abscesses and allowing samples to be taken for culture, for example bone to diagnose osteomyelitis. Skin repair techniques include direct closure, skin grafts and the use of skin flaps. Antibiotics should only be used if there is evidence of systemic sepsis, spreading cellulitis or underlying osteomyelitis. X-rays only become abnormal beyond two weeks when significant bone mineral content has been lost. A positive culture from bone biopsy provides a definitive diagnosis, but a positive blood culture with supportive imaging studies may make this unnecessary. Treatment may require surgical debridement and a prolonged course of antibiotics. In type 2 diabetes the pancreatic beta cells are preserved, but their insulin secretion is reduced. Risk factors for type 2 diabetes include a family history, obesity and a past history of gestational diabetes. Ageing leads to reduced insulin secretion, peripheral insulin resistance, and an increased proportion of body fat (see p. Insulin resistance may be mediated through reduced intracellular signalling processes. Increased central adiposity and reduced physical exercise are common in older age and may increase insulin resistance. Raised levels of glucose may lead to enhanced protein glycation, which may further accelerate the ageing process. These include beta-blockers, nifedipine, thiazide diuretics, atypical antipsychotics and steroids. Diabetic people are also at a risk of hypoglycaemia (usually secondary to treatment), which may also cause lasting harm. A history of one or more episodes of severe hypoglycaemia is associated with an increased risk of developing dementia. Cognitive impairment, taking irregular meals, and a high alcohol intake all make it more likely. Mortality rates increase with age, being <10% in those <75 years, 19% in those aged 75 to 84, and 35% in those >85 years. Standard diagnostic definitions of diabetes are listed below (just one of the three is required). Typical symptoms (polyuria, polydipsia and weight loss) plus a random glucose of 11. As red blood cells survive in the circulation for two to three months, its value reflects blood sugar levels over this preceding period. It is used to measure glucose control and has recently also been used in diagnosis. Traditionally it has been reported as a percentage, but laboratories are now moving towards using mmol/mol units. Serum creatinine should be measured and urinary protein (dipsticks or 24-hour urine) evaluated to look for evidence of nephropathy.

Bilateral diseases are associated with bilateral hydronephrosis antibiotics for uti and alcohol generic fucidin 10 gm visa, hydroureter do antibiotics for uti cause yeast infections discount fucidin 10gm overnight delivery, a large thick-walled bladder and oligo- or anhydramnios antibiotics for uti nz order 10 gm fucidin with mastercard. Normal echogenicity of the renal cortex does not always exclude dyspepsia so a serial assessment of the renal cortex is essential bacteria kpc purchase fucidin with american express. In the absence of other abnormalities and contralateral renal disease antibiotic omnicef fucidin 10gm overnight delivery, the prognosis of unilateral disease is good and it can be managed conservatively antibiotics cephalexin discount fucidin online american express. Renal obstruction Urinary tract obstruction in the midtrimester of pregnancy will manifest as renal pelvic dilatation or hydronephrosis. This condition is seen commonly in males with an overall incidence of 1 in 2,000 live births. Evidence of cortical dysplasia in the form of increased echogenicity or small cortical cyst can be seen in severe disease. It is essential to assess the contralateral kidney to rule out bilateral disease or other associated renal abnormality, such as renal agenesis, multicystic dysplastic kidney, which can be seen in about 25% cases[19]. A neonatologist should be informed and the baby will need prophylactic antibiotics. Although the majority of cases are managed conservatively, severe disease with poor differential renal function will need surgical correction to prevent further renal cortical damage. Severity of renal pelvic dilatation during antenatal period correlates well with the degree of renal impairment. Due to the sporadic nature of the condition, the risk of recurrence in any future pregnancy is low. In a unilateral disease, the bladder and liquor volume are usually normal but may be reduced in bilateral disease. A follow-up scan in the third trimester should be arranged to assess liquor volume and severity of the condition. During the neonatal period, the baby will need prophylactic antibiotics until further investigations rule out vesicoureteric reflux. In cases of severe disease with deteriorating renal function, ureteric reimplantation will be required. Bladder outlet obstruction Bladder outlet obstruction could be due to posterior urethral valve or urethral atresia. Posterior urethral valve this condition only affects males with an overall incidence of 1 in 5,000 to 8,000. The presence of a membranous tissue within the posterior urethra leads to bladder neck obstruction. There will be oligohydramnios or anhydramnios along with hydroureter and hydronephrosis. The condition should be differentiated from urethral atresia, severe bilateral vesicoureteric reflux and megacystis-microcolon syndrome. It is important to rule out chromosomal anomaly in cases of posterior urethral valve, which is seen in about 8% of cases. Prognosis depends on the severity of the disease and gestational age of diagnosis. Diagnosis before 24 weeks, oligohydramnios, hydroureter and hydronephrosis, along with echogenic/cystic renal cortex, indicate very poor prognosis[21]. Termination of pregnancy can be offered in the poor prognostic group; on the other hand, conservative management is appropriate where the liquor volume is normal and hydronephrosis remain stable. Vesicoureteric reflux Vesicoureteric reflux accounts for about 10% of all fetal hydronephrosis and about 20% of all prenatally detected significant renal abnormality[20]. Bilateral or unilateral dilatation of the renal pelvis may be the only feature of vesicoureteric reflux. In severe cases there will be associated ureteric dilatation and thin-walled distended bladder. Bladder neck obstruction needs to be considered in cases of bilateral disease with distended bladder. A follow-up scan at the third trimester is essential to assess the severity of the disease and liquor volume. Vesicoureteric reflux can lead to renal scarring and reflux nephropathy if not treated appropriately. The majority (70%) of mild reflux can resolve spontaneously in the first few months of life, but spontaneous resolution is seen in around 40% of severe refluxes by 15 months of age[24]. Reflux disease is thought to be genetically linked as there is high risk of recurrence. Two-thirds of babies will be affected if the mother suffers from reflux and one-third of siblings of an affected child will have reflux[25]. A sagittal scan of a 15-week fetus showing distended bladder (B) occupying the whole abdomen with no dilatation of posterior urethra. It is important to discuss in a multidisciplinary team involving the fetal medicine consultant, neonatologist and pediatric urologist. Urethral atresia Urethral atresia results from incomplete canalization of distal urogenital sinus, which forms the proximal urethra. This is seen more commonly in males and may constitute up to 60% of all prenatal diagnosed bladder neck obstruction[22]. The presence of a distended bladder, severe oligohydramnios/anhydramnios, hydroureter and hydronephrosis are characteristics of urethral atresia. The absence of a dilated proximal urethra will differentiate this condition from posterior urethral valve. Chromosomal and other structural anomalies are associated in about two-thirds of the cases. It may be difficult to rule out structural anomalies due to the presence of anhydramnios. Termination of pregnancy is an appropriate management option due to poor prognosis of the baby. The majority of the babies will die in the early neonatal period due to pulmonary hypoplasia. Exact etiology is unknown but it manifests as a functional small bowel obstruction with nonobstructed distended urinary bladder. The antenatal scan will show a distended thick-walled bladder with bilateral hydronephrosis. The presence of normal or excessive liquor will differentiate it from posterior urethral valve. The past history of an affected sibling and a female baby are two important factors in diagnosing this condition. Termination of pregnancy is an appropriate option, particularly when there is a family history. Vesicoureteric reflux is commonly associated with this condition and can affect the lower pole moiety. A follow-up scan in the third trimester is essential to assess the liquor volume and renal parenchyma of the affected kidney. Cloacal exstrophy Cloacal exstrophy is a sporadic condition with an incidence of 1 in 250,000 live births[26]. Rupture of the cloacal membrane before the completion of caudal growth of the urorectal septum will lead to this abnormality. It is usually manifested as bladder exstrophy, herniation of small and large bowels through the lower part of anterior abdominal wall and bifid phallus. An exomphalus and lumbosacral spina bifida are usually associated with this abnormality. An absent bladder and an anterior abdominal wall defect below the umbilicus on the antenatal scan will lead to a strong suspicion of cloacal exstrophy. Liquor volume is usually normal but sometimes the condition can be associated with polyhydramnios. Renal anomalies, such as unilateral renal agenesis, pelvic kidney and multicystic kidney, are the most common association. Absence of bladder and defect below the umbilicus will differentiate this condition from exomphalus and gastroschisis. Ureterocele Stenosis of distal ureteric orifice leads to dilatation of the intravesical part of the ureter, which is known as ureterocele. Sometimes a large ureterocele can obstruct the contralateral ureteric orifice leading to hydroureter and hydronephrosis of the opposite kidney. Bladder exstrophy Rupture of cloacal membrane after the completion of caudal growth of urorectal septum will cause bladder exstrophy. The condition is commonly seen in males with an overall incidence of 1 in 30,000 live births[27]. Ultrasonographic features of absent bladder, along with lower abdominal bulge, a small penis along with anteriorly displaced scrotum, normal liquor and kidneys, are suggestive of bladder exstrophy. Other anomalies are usually not associated with this condition, which differentiates it from cloacal exstrophy. Long-term prognosis following surgical correction after delivery is generally good. Ambiguous genitalia It is a rare disorder caused either by chromosomal abnormality or by abnormal hormonal effect. Female pseudohermaphroditism is due to either maternal ingestion of androgen or congenital adrenal hyperplasia. The abnormal response of external genitalia to testosterone or under production of testosterone in a genetically male fetus will lead to male pseudohermaphroditism. In this condition, a male fetus will have a blind vagina or micropenis with or without cryptorchidism. Chromosomal defects such as mixed gonadal dysgenesis, pure gonadal dysgenesis and true hermaphroditism are the other causes of ambiguous genitalia. Ultrasound features of male genitalia in a genetically female baby are suggestive of congenital adrenal hyperplasia. Diagnosis can be confirmed by estimating 17-hydroxyprogesterone levels in amniotic fluid. A follow-up scan in the latter half of pregnancy will be helpful to assess fetal genitalia but not accurate enough to assign a gender during the antenatal period. Ovarian cyst Ovarian cysts are relatively common intra-abdominal cystic lesions in the female fetus. Ovarian cysts develop in response to high maternal hormones and resolve spontaneously after delivery. Absence of two umbilical arteries surrounding the cyst will differentiate it from the fetal bladder. A transabdominal aspiration of the cyst is an appropriate option in those circumstances. A scan during the neonatal period will confirm the diagnosis and assess the size of the cyst. Hydronephrosis secondary to uretero-pelvic obstruction in children: a review of 14 years experience.

Measurement of fetal urine production in mild infantile polycystic kidney disease-a case report. First and second trimester diagnosis of fetal urinary tract anomalies using transvaginal ultrasound. Ultrasound is helpful to determine tumor location, content (solid, cystic, mixed or calcified), vascular involvement, compressive effects, as well as likely tissue of origin. Furthermore, serial ultrasound assessments allow monitoring of growth and cardiovascular effects. It is important to remember that tumors may have significant effects on fetal prognosis either directly, due to pressure effects, or secondary to effects upon the fetal circulation. On histological assessment, two-thirds of fetal tumors are lymphangiomas (25%), rhabdomyomas (23%), teratomas (17%) or hemangiomas (14%). Generally the prognosis is poor and worse if the diagnosis is made prior to 30 weeks where mortality secondary to severe hydrocephalus can be up to 96%[3]. Hydrocephalus and macrocephaly develop secondary to obstruction of the ventricular system and cerebrospinal fluid outflow. Rapid growth of a tumor may also lead to macrocephaly secondary to tumor size or the development of hydrops due to cardiovascular compromise. Pediatric neurosurgeons should be involved in the development of a multidisciplinary management plan. Delivery may be complicated by the presence of significant macrocephaly and cesarean section or predelivery decompression of the skull may be required to prevent labor dystocia. Most will be located within the ventricles, hypothalamic, suprasellar or cerebral regions. Calcifications Solid interventricular lesion Single or multiple intramural hyperechoic masses Solid and cystic components calcifications Cystic, solid or mixed appearance. Teratomas comprise tissue from all three germ cell layers with immature neuroglial elements. Prognosis is extremely poor and is related to the size of the tumor and presence of associated hydrocephalus. A third will die in utero with only 12% surviving the neonatal period and 7% reaching 1 year of age[5].

Intrauterine contraceptives can be inserted immediately following medical and surgical abortion at all gestations infection going around order fucidin 10gm without prescription. A systematic review of the literature concluded that the provision of combined oral contraceptives immediately following surgical or medical abortion was safe[9] antibiotic lupin 500 fucidin 10gm amex. The World Health Organization recommends that progestogen-only contraceptive pills antibiotics with penicillin buy genuine fucidin on-line, implants and injectables can all be started immediately following induced abortion; if started on the day of the abortion antibiotic toxicity order on line fucidin, contraceptive protection is immediate[10] are you contagious on antibiotics for sinus infection buy fucidin 10gm otc. Staff caring for women undergoing medical abortion for fetal abnormality must be sensitive to the fact that some women or couples may express a wish to see or hold the fetus antibiotics for mrsa buy fucidin with a mastercard. They should be made aware of the possible appearance of the fetus with respect to the gestational age and any structural abnormalities. They may wish to have mementoes, such as hand and footprints and photographs, and if not, staff should offer to store them securely in the case records for future access. Keeping such mementoes has not been associated with adverse outcomes and qualitative studies have shown that many couples value them highly[11]. Induced abortion for fetal abnormality can have significant psychologic consequences. In a longitudinal study, 4 months after abortion, 46% of 147 women showed pathologic levels of post-traumatic stress symptoms, decreasing to 20% after 16 months. The most important predictor of persistent impaired psychologic outcome was outcome at 4 months; other predictors were low self-efficacy, high levels of doubt during decision making, lack of partner support, being religious and advanced gestational age. It is also associated with long-lasting consequences for a substantial number of women. Women who experienced little support from their partners and were low educated had the most unfavorable psychologic outcome. Advanced gestational age at the time of abortion was associated with higher levels of grief, and post-traumatic stress symptoms and long-term psychologic morbidity were rare with abortions before 14 weeks of gestation[13]. Referral should be available to any woman who may require additional support, including the possibility of self-referral. There should also be an awareness that partners may experience adverse psychologic sequelae, such as extreme grief reactions and post-traumatic stress disorder[11]. Sensitive disposal of fetal tissue All fetal tissue under 24 weeks of gestation, whether resulting from miscarriage or induced abortion, must be treated with dignity and respect[14]. Local policies should reflect the Human Tissue Authorities Code of Practice 5, "Disposal of human tissue for fetuses born dead at or before 24 weeks of gestation"[15]. Whilst fetal tissue from a pregnancy under 24 weeks may be incinerated, by the year 2000 this practice was felt to be unacceptable by health professionals working within this area[14]. This information must be freely available, taking into account any particular needs of the woman or couple, such as literacy skills and language. Verbal and written information should be provided by trained health professionals. The information should specify who a woman or couple should contact if they would like to request a particular option and in what timescale[17]. Many hospitals have specific staff, such as bereavement support officers, to fulfill this role. Staff should be sensitive to the values and beliefs of a wide range of cultures and religions, particularly those of their local community. However, they should be aware that each decision is one for the individual concerned. A hospital should ensure that the necessary training and support is given so that staff are equipped to identify and meet the widest possible range of needs and wishes[14]. Provided that they have been made aware that the information is available, these wishes should be respected. It is acknowledged that sometimes parents do not recognize their loss at the time, but may return months or even years later to enquire about disposal arrangements. It is therefore important that there is a well-documented audit trail to provide those details if needed at a later date[14]. Confidentiality must be ensured and it should not be possible to identify any individual from the information held by a crematorium or place of burial. Both burial and cremation should be available to allow for cultural and religious differences. The woman or couple should be informed and involved as appropriate and they and their family can choose whether to attend or not. In Scotland, there is an issue of whether multiple cremation and burial is allowed. Local policies may preclude it and if problems are encountered, advice can be sought from the Institute of Cemetery and Crematorium Management [14]. The woman or couple should be made aware that they can arrange a private burial or cremation themselves if they wish but that they may have to incur some or all of the costs. The hospital should facilitate the arrangements and provide the necessary documentation. There is no legal prohibition to burial outside a cemetery but certain requirements must be met. For instance, it must not cause a danger to the public, risk contamination of water supplies and must be buried to a depth of at least 45 cm. Many hospitals provide a book of remembrance that is kept in a significant place, usually the hospital chapel. Parents should be informed of this and be aware that they can arrange for an entry to be placed in the book at any time. It is becoming commonplace to offer a regular service of remembrance to which couples are invited to attend. The format of this service should reflect the cultural, spiritual and diverse needs of the community the hospital serves. Some units have developed a checklist to ensure that all the necessary information has been discussed. Many hospitals are looking at the issue of consent for disposal; some are including it on the consent form for the procedure or on a consent form for histologic examination[14]. Discharge When a woman is ready to be discharged, there must be a clear well-organized plan for her follow-up and ongoing care. Women have reported inadequacies in aftercare that have tested their psychologic resources[18]. Verbal and written information should be provided about symptoms that a woman may experience after an induced abortion and how to recognize complications, particularly those that require urgent medical consultation. The medication required should be prescribed before the woman leaves the hospital. The woman should be provided with contact details for clinical advice to contact hospital staff responsible for disposal arrangements, such as the bereavement support officer and relevant administration staff. All key staff responsible for the care of the woman during pregnancy and afterwards should be informed about the outcome. Timely and appropriate communication between the hospital and primary care team is essential. The general practitioner must be informed when the woman is to be discharged and a home visit by the community midwife should be offered[19]. There should be a reliable system for ensuring that all existing hospital and community appointments are cancelled[1]. Many women find it difficult to return to the hospital and this will be exacerbated if they are asked to wait in a busy antenatal clinic with expectant mothers[1]. An appointment to discuss postmortem results, if applicable, should be arranged as soon as possible. Any unavoidable delays must be explained to the woman or couple and the stress this may cause acknowledged. Many women will be anxious about this appointment because of the potential implications for future pregnancies. If there are options for interventions to reduce the risk of a recurrence, such as high-dose folic acid therapy, these should be discussed. A provisional plan for antenatal diagnosis in a subsequent pregnancy should be drawn up. The next pregnancy is likely to cause anxiety for most women and will require sensitive management, with a care plan agreed as early in the pregnancy as possible[1].

Long-term psychological consequences of pregnancy termination for fetal abnormality: a cross-sectional study. Single dose cabergoline versus bromocriptine in inhibition of puerperal lactation: randomised, double blind, multicentre study. Postpartum return of pituitary and ovarian activity during lactation inhibition with the new dopamine 2. A fertilized egg goes through multiple cycles of duplication and differentiation, followed by cell hyperplasia and hypertrophy in the uterus, to form a baby that is ready to be born. Thus, there is not much fetal weight gain with an average growth rate of about 5 g/day. This intricate process is controlled by a wide range of factors including genetic potential for growth, maternal health and nutrition, placental perfusion and function, fetal condition, and environmental factors. However, many of these are not diagnosed antenatally due to failure in identifying at risk pregnancies and lack of a robust screening strategy. Furthermore, studies are hampered from the inconsistencies in the definition of growth disorders. Yet, accurate prenatal assessment of fetal growth is essential to identify these fetuses for appropriate monitoring and intervention, which can result in improved pregnancy outcomes. Another common definition is the failure of the fetus to achieve a weight threshold, usually defined as the 10th centile. However, these definitions do not take into account growth velocity and include a proportion of babies who are constitutionally small, thus normal and healthy. They are two distinct entities of different etiology, pathology, and management strategies (Table 21. Although risk factors exist for macrosomia, no combination can predict macrosomia adequately for it to be used clinically. Etiology of fetal growth disorders the determination of fetal size is multifactorial and can be divided into maternal, fetal or environmental factors. Failure of one or combination of any of these factors results in abnormal fetal growth (Table 21. Ideally, this results in a low-resistance circulation, promoting increased blood supply to the placental bed. A macrosomic baby is a sign of poorly controlled diabetes, due to hyperglycemia in the fetus. This stimulates insulin, insulin-like growth factor, growth hormone and other growth factors, which results in stimulation of fetal growth and deposition of fat and glycogen. There are usually other features on ultrasound findings, such as macroglossia, organomegaly and abnormal digits, that raise the suspicion of this syndrome in a macrosomic fetus. A fetus that is of advanced gestational age may be large as fetal growth continues in utero. Prior to making any diagnosis, it is of upmost importance that the pregnancy has been accurately dated, and the fetus is of the right gestational age. History Many risk factors for growth disorders such as advanced maternal age, nulliparity, extremes of body mass index, smoking and poor diet, can be identified at the booking appointment. Customized charts Growth and birthweights vary with maternal characteristics such as weight at first antenatal-clinic visit, height, parity, and ethnic origin, and other factors, including birthweight of previous babies and fetal sex. However, antenatal population growth charts do not take into account these variables. A growth chart should be computer-generated and "customized" for each individual during pregnancy, taking into consideration the factors stated above[3]. On normal population charts, up to 50% of fetuses in the <10th centile category would be normal and constitutionally small. The same principle also applies in macrosomia where the baby has exceeded its growth potential if growth plots above the 90th centile on the customized chart. The ultrasound assessment will address the issue of fetal size and polyhydramnios, and should prompt a re-evaluation of the fetus for structural anomalies. The International Fetal and Newborn Growth Consortium for the 21st Century Project has recently published international growth and size standards for fetuses in a multicenter, population-based setting in eight countries where health and nutritional needs for mothers were met and adequate antenatal care was provided[6]. The 3rd, 5th, 10th, 50th, 90th, 95th and 97th centile curves were generated for these ultrasound measures, representing the international standards for fetal growth. The researchers found that fetal growth and newborn size at birth were very similar across countries, if the mothers were healthy and well educated. The findings of the study challenge the widely held belief that race and ethnicity are primary factors for weight at birth. Since publication of the study, there has been widespread debate on the need to customize fetal growth charts based on maternal variables and whether "one size fits all. In view of this, serial growth scans and close monitoring is recommended if this is found[2]. Although there are considerable variations in the accuracy, they are generally acceptable for birthweights up to 3500 g. Fetal Dopplers Referral for further assessment of detailed Doppler studies depends on the customized growth chart pattern where consecutive measurements show either tapering of growth, static growth or exponential growth.

Breathing is also an indicator of overall fetal well being and is a component of the biophysical profile. On T1-weighted images, the lungs are intermediate signal intensity, not significantly different from surrounding soft tissues; most lung masses are not well evaluated with this sequence. The liver is higher in signal intensity than lung, fluid-filled small bowel is low in signal intensity, but meconium-filled large bowel will be high in signal intensity. On T2-weighted imaging, the lungs are higher in signal intensity than the surrounding musculature. The signal intensity of the lungs increases throughout gestation reflecting the fluid within the enlarging alveoli. It has an intermediate signal intensity on T2weighted images and is located in the superior portion of the mediastinum, often displaying angular borders. Approach to Fetal Chest Mass It is important to have a systematic approach when viewing the fetal chest and developing an appropriate differential for a chest mass. Each of the diagnostic entities will be discussed in detail in the subsequent chapters. Any shift in the cardiac axis is highly suspicious for a thoracic mass or, alternatively, a cardiac defect. While a normal axis rules out most significant chest masses, small masses may not necessarily deviate the axis and may be missed. It is important to note, however, that a left-sided hernia may contain only bowel &/or liver, with the stomach remaining below the diaphragm. This is the first and most important question once it has been determined that a chest mass is present. The lung will float within an effusion and have a wing-like appearance, while a cystic mass will displace and compress the lung. Lymphangiomas have the bulk of the mass in the subcutaneous tissues, with secondary intrathoracic involvement. The development of hydrops is a poor prognostic sign and may warrant clinical intervention. The reasons are not entirely clear, but it may be that an open diaphragmatic defect decreases the compressive forces on mediastinal structures. Because the cardiac axis is often distorted, it may be more difficult to adequately evaluate, and a dedicated fetal echo may be warranted. This is ultimately the most important question in evaluating any fetus with a chest mass. There are no universally accepted criteria for predicting hypoplasia, and a plethora of measurements and ratios exist. This is likely the result of disruption of normal fetal breathing as well as mass effect. The defect is posterior with herniation of the stomach and small bowel into the left hemithorax. Note that the anterior diaphragm remains intact, stressing the importance of the sagittal plane when evaluating the diaphragm. Always look for portal and hepatic veins with Doppler to confirm the position of the liver. It can be calculated by either tracing the area or multiplying the longest diameters (calipers). The tracing method is preferred as the area can be overestimated by as much as 45% using the longest diameters. The herniated portion continues to grow in a confined space, which can constrict blood supply and make it more difficult to reduce at surgery (liver lock). Note the herniated liver is slightly higher in signal compared to the abdominal portion suggesting edema. The heart is displaced slightly superiorly, but the axis was normal on the standard 4chamber view. Developing hydrops portends a very poor prognosis, so the patient was treated with betamethasone. If hydrops is progressive despite treatment, consider referral to a fetal surgery center. This was monitored closely for development of hydrops, but on subsequent scans, it became less obvious. The primary differential for this appearance is a congenital diaphragmatic hernia. It is important to document an intact diaphragm and normal position of the stomach. It is covered with its own pleural investment, and there is no communication with the tracheobronchial tree. Color Doppler is extremely helpful in situations like this as the feeding vessel is usually easy to find. This arises from the aorta, or other systemic vessel, and is usually readily identifiable by color Doppler. The mass is triangular and hyperechoic, with the normal lung floating posteriorly. An anomalous supernumerary bud from the primitive foregut does not come in contact with the surrounding primitive mesenchyme (pink) like the normally developing bronchi. The original communication with the foregut typically involutes, resulting in a blind-ending pouch or cyst. Chatterjee D et al: Ex utero intrapartum treatment to resection of a bronchogenic cyst causing airway compression. High airway obstruction causes retention of fetal lung fluid and subsequent overdevelopment of the lungs. The right lung was normal and there was no evidence of a congenital diaphragmatic hernia. This fetus survived but had unexpected coarctation of the aorta with a stormy postop course due to pulmonary hypertension. Multiple cysts along the left chest, neck, and arm have formed because of congenital lymphatic obstruction. Normal lymphatic drainage anatomy with a patent jugular lymphatic connection is shown on the fetal right. The delivery was uncomplicated, and intubation was not required, as suggested by the prenatal imaging. Arisoy R et al: Prenatal diagnosis and outcome of lymphangiomas and its relationship with fetal chromosomal abnormalities. Masslike areas of anechoic septated cysts are present in the subcutaneous tissues, distinguishing lymphangioma from skin edema, which is usually diffuse and uniform. The medial margin of the mass does not encase the airway, which is valuable information for delivery planning. The medial portion of the mass abuts the airway, but the airway is widely patent, and intubation was not required. There is compression of the heart resulting in hydrops with skin edema and ascites. At delivery, an endotracheal tube was placed and the mass, a wellencapsulated teratoma, was immediately resected. Even when successfully resected, there can be long-term morbidity from tracheomalacia. Simoncic M et al: Mediastinal teratoma with hydrops fetalis in a newborn and development of chronic respiratory insufficiency. The echogenicity is closer to liver than lung, and there are fine linear striations. The anterior location and imaging appearance are classic for a normal thymus, which can be quite prominent in a fetus. The thymus will be flanked on either side by the internal mammary arteries creating what has been referred to as the thybox. Bronchopulmonary Sequestration Congenital Diaphragmatic Hernia (Left) Axial ultrasound through the chest in a fetus with a left-sided diaphragmatic hernia shows the liver appearing as a uniformly echogenic chest mass, which is compressing the heart against the right chest wall. Congenital Diaphragmatic Hernia Mediastinal Teratoma (Left) Coronal ultrasound through the anterior chest shows a large complex mass. Calcifications are the most specific finding of a teratoma but are not always present. A teratoma can grow at a very rapid rate and quickly lead to fetal decompensation. Congenital High Airway Obstruction Sequence Congenital High Airway Obstruction Sequence (Left) Axial ultrasound through the fetal chest shows hyperexpanded lungs with compression of the heart in the midline. Tracheal obstruction causes retention of fetal lung fluid and subsequent overgrowth. The stomach is the most obvious fluid collection, but the small bowel is also herniated with the multiple interfaces creating a complex appearance. The heart is displaced to the right, and the compressed right lung is being measured by the calipers. Lymphangioma Lymphangioma (Left) Axial ultrasound shows bilateral, large, complex, multiloculated chest wall masses. Lymphangiomas are typically soft tissue masses but can extend into the mediastinum. Bronchogenic Cyst Neurenteric Cyst (Left) Axial ultrasound through the chest shows a centrally located, small, unilocular cyst, which remained stable throughout gestation. The secondary heart field lying contiguous with, but medial to , the primary cardiac crescent populates the outflow tract and primordium of the right ventricle. As the embryo elongates and folds, the limbs of the crescent come together in the midline and fuse, creating the heart tube (which moves into the thorax). The proximal, venous pole remains anchored dorsal and will become part of the atria, while the arterial pole bends rightward and ventral and will become the outflow tract. The right and left ventricles are shown as well as the eventual right atrium and great vessels. The left ventricle is derived from the primary heart field (red), the right ventricle, and outflows from the secondary heart field (blue). The tertiary field (orange) contributes to formation of the atria and provides cellular components to the ventricles. Note the moderator band in the trabeculated right ventricle; this can be used to identify the morphologic right ventricle, which should always be the anterior ventricle. Note that the flap of the foramen ovale is in the left atrium, which signifies right-to-left flow with the oxygenated stream of blood from the umbilical vein and ductus venosus crossing to the left to provide oxygenated blood to the brain. The tricuspid valve is seen in cross section in the center of the right ventricular cavity. A defect in this area may simply be an isolated perimembranous ventricular septal defect but may also be found in association with right ventricular outflow tract or conotruncal lesions, such as tetralogy of Fallot or double outlet right ventricle. It allows one to lay out the main pulmonary artery and the ductus arteriosus as it runs posteriorly, toward the spine, to join the descending aorta. The regurgitation is secondary to myocardial ischemia and impaired ventricular contraction. Note the right vein is blue, so the probe is anterior and to the right of the fetus. The left superior vena cava drains into the right atrium via the coronary sinus, which is enlarged due to the increased volume of blood entering it. Be careful to check for anomalous pulmonary venous return to the coronary sinus, another important cause of dilation of this structure. This highly oxygenated blood (red) shunts through the ductus venosus and streams across the foramen ovale to the left side of the heart, supplying the head. Deoxygenated blood (blue) returns to the right atrium via the superior and inferior vena cavae. This blood preferentially flows to the right ventricle, which pumps a small amount to the pulmonary arteries but most across the ductus arteriosus. Deoxygenated blood returns via the superior and inferior vena cavae to the right side of the heart, which pumps deoxygenated blood to the lungs for gas exchange. The umbilical arteries become the medial umbilical ligaments, the umbilical vein becomes the ligamentum teres, and the ductus arteriosus becomes the ligamentum arteriosum. In the standard scan, the goal is to document the 4-chamber view and both outflow tracts. Additional cardiac images required for the complex scan are the 3-vessel view, the aortic arch, and the bicaval view. Determination of the fetal position by establishing left and right, anterior and posterior, and superior and inferior aspects of the fetus is vital. One cannot rely on position of the organs, since their position may vary from normal, especially in cases of heterotaxy. Once left and right are established, the heart and stomach can be used as points of reference in addition to the fetal spine. After the position in the maternal pelvis is determined, and there is correct identification of left and right, one should start with a transverse (axial) cut through the fetal chest. A sweep in this orientation in a normal fetus will show the stomach and heart on the left with the inferior vena cava draining into the right atrium. To obtain a true cross section of the thorax, rotate the transducer until only one rib is seen on each side.
