Practising paediatrics under these conditions means that you will need to anticipate what could happen next hair loss cure - medicinal plants dutas 0.5mg visa, which can be very difficult hair loss in men khaki best purchase dutas. Then hair loss in men 34 cheap dutas 0.5 mg with amex, we shall cover most of what is needed next for acute care-knowledge hair loss cure etf buy dutas 0.5 mg lowest price, assessments hair loss medication buy 0.5mg dutas overnight delivery, and treatments hair loss cure 5 bolt discount dutas 0.5mg with mastercard. A-establish an airway Provide oxygen Use fractional inspired oxygen (FiO2) 100%; use the optimum method for patient size and monitor. With regard to fluid therapy, we generally restrict total volume to 80% maintenance for the following reasons. After initial symptoms, there may be an asymptomatic period followed by features of pneumonia (see b p. When water has been aspirated in to the lungs it is usually a small amount (<22mL/kg). Assess the duration of submersion, water temperature, and presence of cyanosis or apnoea. Emergency staff should provide details of resuscitation and the time taken to establish a pulse and cardiac output. If there is no gagging, hypoxaemia, or apnoea, then endotracheal intubation is needed. In profound hypothermia, more invasive methods of warming may be used on the intensive care unit. Look closely for signs of lower respiratory tract involvement: use of accessory respiratory muscles, nasal flaring, tachypnoea, cough, wheeze, and crackles. Hypotension is a late sign, so look for a decreased stroke volume (decreased pulse amplitude) and increased systemic vascular resistance (perfusion changes to skin and muscle). Hypertension To diagnose hypertension strict criteria should be followed: three measurements in non-stressful circumstances with values >2 standard deviations above mean for age and sex. Congenital heart disease In cyanotic babies the history and examination can be used to exclude respiratory causes of cyanosis. The assessment also includes the hyperoxia test (measurement of PaO2 in FiO2 100%). Anaemic patients may not become cyanotic even in the presence of marked arterial desaturation. In light-skinned patients, cyanosis is usually noted with arterial saturation <85%. Respiratory In the neonate increased respiratory rate (usually <80breaths/min) with no respiratory distress suggests cyanotic heart disease, but with respiratory distress pulmonary disease is suggested. In the older child a full respiratory examination is required-look at all components of the examinations. After 30s exposure to air, normal blood turns red, while blood taken from a patient with methaemoglobinaemia remains chocolate brown. In the neonate the lung fields should be assessed for signs of increased vascularity, pulmonary congestion, or oligaemia. Therapy Therapies for specific cardiac, respiratory, and poisoning conditions are discussed elsewhere. Aetiology the symptoms of anaphylaxis are abrupt, often within minutes of exposure to an antigen. Diagnosis Take a careful history and aim to determine the time between onset of symptoms and exposure to the potential precipitating cause. The most common type, hypovolaemic shock, is related to abnormally low circulating blood volume. If more than 60mL/kg is required consider endotracheal intubation and ventilatory support. In the patient who is dehydrated, the water and electrolyte deficit needs to be replaced (see, b pp. The severity of a burn to the skin is assessed according to its severity and total surface area. Surface area the extent of the burn as a proportion of the body surface area (% body surface area) can be calculated by making a sum of the individual areas involved in the injury. Investigations Minor burns There is no need for routine investigations in children with minor burns, i. Further fluid resuscitation should be directed toward maintaining a urine output of 0. In this section we will consider the recognition and specific treatment for sepsis. Clinical assessment Clinically, there may be fever in the older child, but be aware that fever or hypothermia can be the presenting feature in the infant. Investigations All organ systems may be involved in sepsis so it is important to perform the following tests. This can wait until you have stabilized the child-you may even have to defer it if there is any coagulopathy. In general, you can start with a third generation cephalosporin and use the following antibiotics for specific groups of patients. Indwelling catheter Consider Staphylococcus aureus-anti-staphylococcal cover that is appropriate in your institution. Occurs with lesions from midbrain to midpons, and with bilateral anterior cerebral lesions. A score d8 is used as a criterion for endotracheal intubation in the head-injured. Cranial imaging should only be performed if the child is well enough to leave the emergency department, i. The choice will depend on local epidemiology, public health, immunization, and antibiotic policy. However, in practical terms, once a child has been fitting for more than 5min, the chances of the seizure lasting more than 30min are dramatically increased, and therefore the common practice is to start therapy at this point. At any stage, if there is respiratory depression, intubate the trachea and support breathing. Hence, the advice to parents that home oxygen is not indicated for the treatment of StE. Roll in to the recovery position, keep the oxygen running, watch the SpO2, and other observations carefully. In older children, accidental selfpoisoning should be suspected as a possible suicide gesture. Aetiology Parents usually know the name and often have a good idea of the amount of material ingested. It is helpful to consider the derangement in body systems and think of potential causes (see Box 5. Diagnosis the likely type of poisoning may be indicated by its clinical effect (see Box 5. Not for tricyclic antidepressant or chloral hydrate overdose, or child with seizure disorder on benzodiazepines. There are a number of ways of calculating daily requirements, but the method we most commonly use is based on patient weight (see Box 5. In the fasting patient, the type of fluid given should contain dextrose (usually 5%), sodium chloride, and added potassium chloride. Its severity can be assessed using change in weight or the following physical signs. In practice, our treatment is aimed at correcting both the water and electrolyte losses (Table 5. Emergency treatment is directed toward restoring any compromise in the circulation. After the initial phase, fluid administration should be calculated to correct deficits over 48hr. Seizures and cerebral oedema may complicate the rehydration phase of hypernatraemic dehydration. The features are low urine volume and high urine osmolality in the absence of hypovolaemia, renal disease, and adrenal disease. Approach Treatment guided by the level, but first repeat a venous sample in case of haemolysis. Children in this state need immediate attention and transfer to a specialized renal unit. More commonly, we see patients with a degree of renal insufficiency that is complicating an acute medical illness-it may be present at the time of presentation or it may evolve during hospital admission. Then, to assess intravascular volume, come to a decision about whether the patient is hypovolaemic or hypervolaemic. Acute renal failure and kidney injury A child in acute renal failure will need to be transferred to a renal unit.

IndIcatIons For antIreFlux surgery Antireflux surgery should be undertaken in the presence of an established esophageal stricture or when conservative measures of treatment have failed hair loss on cats discount dutas 0.5 mg line. Surgery may also be considered at an early stage (1) in the presence of an anatomic anomaly hair loss in men zoot order 0.5mg dutas amex. Pressure recordings are made with continuously perfused hair loss cure garlic purchase dutas 0.5 mg mastercard, open-tipped catheters or solid-state pressure transducers hair loss cure laser cheap dutas 0.5 mg online. Individual pressure values are unreliable diagnostic indicators of reflux hair loss cure trials order dutas 0.5 mg free shipping, but may be useful in predicting cases that will eventually require surgical treatment hair loss young male dutas 0.5 mg with mastercard. Metoclopramide and bethanechol increase lower esophageal pressure and stimulate gastric emptying. Additional exposure may be attained, if necessary, by dividing the left triangular ligament in the avascular plane and then retracting the left lobe of the liver to the right. In older children, especially children with kyphoscoliosis or obese children, the use of the selfretaining retractor is invaluable in obtaining adequate exposure of the operative field. Splenectomy should rarely be necessary in this procedure, even in revision fundoplication operations. A rubber sling is placed around the esophagus incorporating the posterior vagus nerve, which will be included in the fundoplication. It is important not to twist the stomach during this maneuver and to ensure that the stomach has been sufficiently mobilized to be able to fashion a loose wrap. Commencing at the level of the gastroesophageal junction, three to four sutures of non-absorbable material (3/0 or 4/0) are placed through the stomach and esophageal muscle. Each suture passes from left to right through the anterior wall of the stomach, through the esophageal muscle (taking care not to enter the lumen of the esophagus), and through the wall of the mobilized portion of the fundus of the stomach, which has been folded behind the esophagus. An additional two or three sutures may be placed between the hiatus and the fundoplication to prevent the wrap migrating in to the posterior mediastinum. A suitable area on the anterior wall of the stomach is selected to permit the gastrostomy site to be anchored to the anterior abdominal wall without exerting traction on the fundoplication. Two rows of circumferentially placed non-absorbable sutures are placed through the seromuscular layer of the stomach. A suitable-size Malecot catheter is inserted through a centrally placed gastrotomy in to the stomach and the sutures are tied, invaginating the gastrotomy site. Laparoscopic nissen fundoplication 347 complications Death following this procedure is extremely uncommon. The gastroesophageal reflux may recur because of either disruption of the fundoplication or herniation of the fundoplication in to the posterior mediastinum. Paraesophageal hernia occurs following inadequate approximation or disruption of the crural repair. Adhesion intestinal obstruction is particularly common if an additional intra-abdominal procedure, such as gastrostomy, incidental appendectomy, or correction of malrotation is performed. In such cases, (1) the gastrostomy can be left in place and the operation is carried out above the gastrostomy or (2) the gastrostomy is taken down the opening on the stomach closed with intracorporeal sutures of 4/0 or 3/0 Prolene sutures. At the end of the procedure, a laparoscopic gastrostomy is fashioned again through a new opening in the anterior wall of the stomach. It is recommended to perform a rectal washout a few hours before the operation to avoid over-distension of the colon and facilitate its retraction below the stomach. The small attendant risk of breaching the left pleural cavity during esophageal mobilization and causing a tension pneumothorax is an additional reason for having complete airway control. A large nasogastric tube is inserted to ensure that the stomach is empty for the duration of the operation. Previous abdominal Video monitor patient positioning 12a An infant is positioned at the foot of the table as per floor plan and the video monitor is placed at the head of the table. Assistant Scrub nurse Surgeon 12b fig Ped42 12b Operative Surgery Paediatrics - 7th ed portPierro plaCeMents Hodder Education 13 the operation is performed with three ports. Two ports for introduction of instruments are placed in the right and left upper quadrant of the abdomen; it is important to insert these ports quite laterally so that a wide angle is created that facilitates the intracorporeal suturing. The liver retractor size is decided on the basis of the size of child and that of the liver. Laparoscopic nissen fundoplication 349 liver retraCtion 14 Using the Nathanson liver retractor, the liver is retracted upwards, allowing dissection of the esophagogastric junction. These adhesions are carefully divided using hook diathermy as the liver retractor is moved in to the desired position. Some loose adventitial tissue attaching the fundus to the diaphragm and left crus can be identified by gentle downward traction on the fundus. Recently, some surgeons have proposed minimal crural dissection to avoid disrupting the natural tissue planes and repairing of the crura only in the presence of hiatus hernia. The left crus must be positively identified before creating the posterior window, otherwise there is a risk of breaching the left pleura, with resultant left tension pneumothorax. It is important to avoid damage to the crura during dissection and creation of the esophageal window. To visualize the crura, the esophagus including the posterior vagal nerve, is lifted anteriorly. This maneuver is facilitated by insertion of a Nylon tape around the esophagogastric junction and elevation of the tape using a grasper inserted in the epigastrium without the need of inserting an extra port. In patients who need a gastrostomy, a 5-mm port can be inserted where the tube gastrostomy will be introduced (see below). The first suture can be replaced after placing a second suture in a more suitable position. The wrap can be completed with three interrupted, non-absorbable sutures, anchoring each of them to the anterior esophageal wall to prevent it from sliding. If a port was inserted in this position, it will be necessary to enlarge the opening to achieve at least a 1-cm opening in the fascia and the peritoneum. A 12 Fr Malecot catheter is inserted and the purse string ligated around the catheter. Pneumoperitoneum is created again and by laparoscopy it is ascertained that (1) the stomach is anchored correctly to the anterior abdominal wall and (2) there is no leaking from the gastrostomy site. Clinical outcome of a randomized controlled blinded trial of open versus laparoscopic Nissen fundoplication in infants and children. If a gastrostomy tube is inserted, the nasogastric tube is removed at the end of the operation and the gastrostomy tube left on drainage. An immediate postoperative complication is dysphagia, which, if sufficiently symptomatic, can be relieved with an early flexible endoscopy or, if not responding, by performing single balloon dilatation. A randomized blinded controlled trial comparing open and laparoscopic Nissen fundoplication in infants and children indicated that there was no difference in the postoperative analgesia requirements and recovery after the two procedures. Early postoperative outcome confirmed equal efficacy, but fewer children had retching after laparoscopy. He treated the patient by fashioning a rod out of a whale bone with a sponge on the end with which the patient was able to force food in to his stomach. In 1877, Zenker and von Ziemssen, and in 1884 Mackenzie, suggested that achalasia was due to diminished contractile power of the esophageal musculature. In 1888, Meltzer and Mikulicz independently postulated that spasmodic contraction of the cardiac sphincter was the etiologic factor. The child learns to eat very slowly and to drink large quantities of fluid to encourage food to enter the stomach. The child with achalasia is often first referred to a psychiatrist for treatment of food aversion or anorexia. Relief of symptoms in children is at best temporary, but may occasionally last for prolonged periods. Recently, it has been shown that botulinum toxin injected in to the lower esophageal sphincter musculature results in symptomatic relief, but the effect is short lived. Controversies concern the length of the myotomy, the extent to which the myotomy extends on to the stomach, and the necessity for an antireflux procedure. The myotomy is covered by a short, floppy Nissen fundoplication to protect against subsequent gastroesophageal reflux. The proximal one-third of the greater curvature of the stomach is liberated from its attachment to the spleen by ligating or coagulating with bipolar diathermy and dividing the short gastric vessels in the gastrosplenic ligament. This is accomplished most safely using a right-angled forceps passed around each vessel in turn. The esophageal hiatus is completely exposed by dividing the upper part of the gastrohepatic omentum above the left gastric vessels. The avascular membrane is incised with scissors and the musculature of the esophagus displayed. The anterior vagal nerve will be seen coursing on the surface of the esophagus; it should be carefully protected and preserved. The divided muscle is gently parted with a blunt hemostat until the underlying mucosa of the esophagus is encountered. The thickness of the muscle of the lower esophagus varies from a few millimeters to 0. The dissection is continued until at least 50 percent of the circumference of the esophagus is free of the overlying muscle. Gastroesophageal reflux is due to an inadequate fundoplication, and dysphagia for solids is due to too tight a fundoplication. Relief of the dysphagia and respiratory problems is usually complete, but residual or recurrent pain may occur in 25 percent of patients and is due to diffuse esophageal spasm. It is recommended to perform esophageal endoscopy and clear the esophagus from retained food after induction of anesthesia. Single shot intravenous perioperative antibiotic prophylaxis is given with induction of anesthesia. Video monitor patient and team positioning 12 the patient is placed in a supine position at the lower end of the operation table. The operation is performed by the surgeon who stands between the legs of the patient and the camera assistant placed to his left. Assistant Scrub nurse Surgeon 12 OperatiOn laparoscopic instrumentation Most patients with symptomatic achalasia are older than ten years of age. Therefore, 10-mm scopes and instruments with a diameter of 5-mm are used, however, the author prefers 3. The grasper for liver retraction may also be introduced directly without using a trocar. In case of difficulties with exposure, an additional 5-mm port may be introduced above the umbilicus right to the falciform ligament for the telescope. The grasper is fixed to the muscular diaphragm by grasping it just above the hiatus. The esophagus should be exposed from the crus down to the esophagogastric junction. An easy plane can be developed between the overarching crus and the esophagus, allowing the esophagus to be exposed in the mediastinum for up to 5 cm. Once an adequate length of intrathoracic esophagus has been exposed, attention should be redirected to the abdominal esophagus. While it is possible to use monopolar diathermy or an ultrasonic scalpel to make this initial myotomy incision, both these instruments can produce deeper thermal damage, which may cause unrecognized damage of the underlying mucosa, resulting in delayed perforation. Dissection is continued down to the gastric junction extending on to the fundus of the stomach, which can be identified when one sees the edge of circular gastric muscle fibers. A mucosal leak can be repaired laparoscopically with an absorbable mucosal suture. The upper sutures are attached to the anterior hiatus to prevent slipping of the wrap. Long-term follow up is essential and clinical assessment is performed at 1, 6, and 12 months postoperatively. Contrast study, pH study, or manometry should only be used in case of persisting or new symptoms. Randomized controlled trial of botulinum toxin versus laparoscopic Heller myotomy for esophageal achalasia. Perforation of the mucosa during myotomy is rare and occurs mainly at the esophagogastric junction. As with fundoplication, there is a small risk of breaching the left pleural cavity during dissection of the anterior wall of the mediastinal esophagus, and a tension pneumothorax may require immediate drainage. Refinements in traditional procedures and the introduction of newer and simpler endoscopically, radiologically, ultrasonographically, and laparoscopically aided gastrostomies have enhanced the safety and expanded the applicability of this operation. It is perhaps fair to state that, over the years, few if any other commonly performed procedure has had as many different approaches as this seemingly simple access to the stomach. The main appeal of the Janeway-type stoma is that the patient does not need a catheter between feedings. The use of automatic stapling devices, including those designed for laparoscopic use, has facilitated the construction of the tube from the anterior gastric wall. In some pediatric centers, non-endoscopic imaging-guided gastrostomies are also regularly employed. Feeding and administration of medications Placement of a gastrostomy for enteral feeding has two prerequisites: (1) the upper gastrointestinal tract must be functional and (2) the need for enteral feedings must be long term, at least several months.

William syndrome Genetic disorder characterized by mild learning disability, unique personality characteristics, distinctive facial features and cardiovascular disease (elastin arteriopathy). A range of connective tissue abnormalities is observed and hypercalcaemia and/or hypercalciuria are common. Wilson syndrome (hepatolenticular degeneration) Disorder of copper metabolism leading to hepatic disease; renal disease; spasticity; tremor and mental problems. Werner syndrome Congenital alopecia, dwarfism, senility, early atherosclerosis, delayed tooth eruption and mandibular hypoplasia. A marathon of eponyms: 7 Gorlin-Goltz syndrome (naevoid basal cell carcinoma syndrome). A marathon of eponyms: 9 Imerslund-Grasbeck syndrome (Juvenile pernicious anaemia). If a specific condition is not found here, please refer to the index, since it may well be located elsewhere in the book. Acanthosis nigricans A rare paraneoplastic condition where papillomatous oral lesions are seen often in patients with internal malignancy. Acatalasia Autosomal recessive defect in the enzyme catalase, which normally removes reactive oxygen species, such as hydrogen peroxide, from tissues. Achondroplasia (chondrodystrophia fetalis) An autosomal dominant condition in which endochondral ossification is reduced. The skull is relatively large, having prominent frontal, occipital and parietal bones. Acrodermatitis enteropathica A rare genetic disorder of zinc metabolism causing mouth ulceration and candidosis, rash around orifices, and alopecia. Actinomycosis A rare infection with Actinomyces israelii, below the mandibular angle (not lymph nodes) that may follow jaw fracture or tooth extraction. Acute necrotizing (ulcerative) gingivitis A non-contagious anaerobic gingival infection associated with overwhelming proliferation of Borrelia vincentii and fusiform bacteria. Uncommon, except in resource-poor groups, this typically affects adolescents and young adults, especially in institutions, armed forces, etc. Characteristic features include severe gingival soreness, profuse bleeding, halitosis and a bad taste. Manage by oral debridement, metronidazole (penicillin if pregnant) and oral hygiene. Fluorosis, tetracycline staining, dentinogenesis imperfecta and oculodentodigital dysplasia may need to be differentiated. Amyloid can be identified via Congo red stain under fluorescent or polarized light, thioflavine T stain under fluorescent light, or immunoreactivity with antibodies for immunoglobulin light chains. Primary (including myeloma-associated) amyloidosis: associated with deposits of immunoglobulin light chains. Manifestations include macroglossia and oral petechiae or blood-filled bullae (secondary purpura). Angina bullosa haemorrhagica (localized oral purpura) Blood blisters in the mouth or pharynx, mainly on soft palate, seen in absence of any immunological or platelet-associated cause. Diagnose from clinical features, although it may be necessary to confirm haemostasis is normal; and rarely to biopsy to exclude pemphigoid. Ankyloglossia (tongue-tie) An uncommon genetic condition which results in the lingual fraenum anchoring the tongue tip, restricting tongue protrusion and lateral movements. Branchial cyst A lymphoepithelial cyst that may arise from enclavement of salivary tissue in a lymph node, or from the cervical sinus. Bullous pemphigoid An autoimmune disease usually with widespread crops of tense, fluid-filled blisters on the skin. Caries Dental caries can occur on any tooth surface exposed to the oral environment, but not surfaces retained within bone. There are four factors in the aetiology: a tooth surface (enamel or dentine); cariogenic (or potentially caries-causing) bacteria in dental plaque; fermentable carbohydrates; and time. The specific bacterial species believed to cause caries include Streptococcus mutans and Lactobacilli. Particularly for root caries, the most closely associated bacteria are Lactobacillus acidophilus, Actinomyces viscosus, Nocardia spp. Sugars (sucrose, glucose, fructose) are metabolized to acetic, lactic, formic and succinic acids. Different individuals are susceptible to different degrees depending on tooth shape, oral hygiene, and the flow and buffering capacity of their saliva. Carotid body tumour A slow-growing, but malignant neoplasm of chromaffin cells that both invades locally and metastasizes. It presents as a mass over the internal carotid artery and transmits the carotid pulsation. Cheek biting (morsicatio buccarum) Common and seen in adults mainly, especially anxious patients, and those with other psychologically related disorders. Abrasion of the superficial epithelium leaves whitish fragments on reddish background. The lesions are invariably restricted to the lower labial mucosa and/or 398 buccal mucosa near the occlusal line on one or both sides. Chemical burns Can be caused by various chemicals or drugs; notably aspirin put in the sulcus to try to relieve toothache, or cocaine. Chikungunya fever A mosquito-borne arboviral illness similar to dengue fever; causes arthralgia and mouth ulceration Chondroma A benign tumour, rare in the jaws. The anterior maxilla, mandibular symphysis and the coronoid and condylar processes are the most common sites. Chondromas are typically found in the older patient and form slow-growing, painless masses. Chondrosarcomas these tend to affect the older patient and, although isolated cases arise from chondromas, most arise de novo. The behaviour is very unpredictable, but many grow rapidly and produce extensive local destruction. Radical surgery, the only means of eradicating the tumour, can be difficult as the edges may not be apparent clinically or radiographically. Multiple local recurrence is common and the prognosis is worse than for osteosarcoma. Chorea Consists of a writhing movement of continuous abrupt and intermittent movements that flow randomly from one part of the body to another. This is usually a late (hence tardive) complication manifesting as non-random, focal patterned or stereotyped movement induced by dopamine receptor blocking drugs, such as metoclopramide, phenothiazines or butyrophenones, and is somewhat similar to oromandibular dystonia. Senile chorea, including edentulous dyskinesia or orodyskinesia, is found in 16% of the edentulous. Chronic ulcerative stomatitis this is similar to erosive lichen planus, with ulcers and erosions affecting mainly the buccal or lingual mucosae, but sometimes the gingivae. Cleidocranial dysplasia (dysostosis) A rare autosomal dominant condition, or mutation. Clinical features include exaggerated transverse diameter of cranium, delayed fontanelle closure, multiple wormian bones, frontal and parietal bossing, depressed nasal bridge, maxillary hypoplasia, underdeveloped paranasal sinuses, high arched palate ( Diagnosis is from the family history and ability to bring together the shoulders; jaw, skull and skeletal radiography. Eruption of permanent teeth is retarded and dentigerous cysts are frequently found. Supernumerary teeth are common in cleidocranial dysplasia, especially in the anterior mandible. The crowns of the teeth are normal, but the roots can be short, thin and lack acellular cement. Coeliac disease Coeliac disease is a reaction to gluten, ingestion of which activates immune cells in the small intestine, which trigger inflammation and local damage, disrupting food absorption. Untreated coeliac patients lose weight, develop deficiency syndromes such as anaemia, and experience symptoms such as diarrhoea. Diagnosis is confirmed by malabsorption, blood tissue transglutaminase antibodies and villous atrophy on jejunal biopsy. Gluten is found in wheat, barley and rye, which means that many dietary staples, such as bread, many breakfast cereals and foods like pizza and pasta, can no longer be eaten. Constricted pupils Constricted pupils (miosis) can be caused by sympathetic nerve lesions, cholinergic drugs. Raised intracranial pressure is the most important cause of pupil constriction and is noted when the pupil also becomes non-reactive owing to pressure on the oculomotor nerve. Cri-du-chat syndrome Short arm of chromosome 5 deletion, resulting in microcephaly, hypertelorism, and laryngeal hypoplasia causing a characteristic shrill cry. Gout itself is an uncommon disorder of metabolism in which excessive levels of uric acid in the blood and other body fluids crystallize out in synovial fluid causing acute inflammation. In chronic gout, tophi are frequently felt in the cartilage of the pinna of the ear. Imaging is not often particularly helpful, since the appearance resembles osteoarthritis. Cysts of the jaws mostly arise from odontogenic epithelium, and are relatively common lesions (Ch. Non-odontogenic developmental cysts are uncommon and were said to form from entrapment of epithelium during the fusion of embryological processes, but this embryological concept has now been discarded. The lining of these cysts is either stratified squamous epithelium or pseudostratified ciliated columnar (respiratory) epithelium. Non-odontogenic cysts include the following: 57 Nasolabial cysts: soft tissue cysts found within the nasolabial fold. They are lined by respiratory epithelium, and if allowed to grow may distort the upper lip and alar base. Cystic hygroma A developmental anomaly of lymphatics presenting as a swelling of the neck seen before the age of 2 years. Dentinogenesis imperfecta A rare autosomal-dominant disorder in which the dentine is abnormal in structure and, hence, translucent. All teeth are affected, but primary teeth are more severely affected than permanent teeth. In the permanent dentition the teeth that develop first are generally more severely affected than those that develop later. The teeth: are translucent may vary in colour from grey to blue or brown enamel is poorly adherent to the abnormal underlying dentine and easily chips and wears crowns are bulbous with pronounced cervical constriction and the roots are short fracture easily (there is progressive obliteration of pulp chambers and root canals with secondary dentine) periapical radiolucencies are not uncommon. Type I (associated with osteogenesis imperfecta): most severe in deciduous dentition; bone fractures; blue sclerae; progressive deafness; caused by mutations in one of several genes. There are three types of dentinogenesis imperfecta: Differentiate mainly from amelogenesis imperfecta, tetracycline staining and dentine dysplasia. Dermatitis herpetiformis An uncommon chronic skin disorder associated often with gluten-sensitive enteropathy, affecting mainly middle-aged males. Oral lesions of vesicles and/or desquamative gingivitis, similar to pemphigoid typically follow skin lesions. Biopsy of perilesional tissue, with histological and immunostaining examination are essential to diagnosis, showing IgA deposits at the papillae. A gluten-free diet can minimize disease activity and can reduce or avoid the need for drugs. Dermatomyositis A rare autoimmune disorder that occasionally presents with oral ulcers and erythema of the tongue, palate or gingivae. They may occur either within the nasopalatine canal, or in the soft tissues of the palate at the opening of the canal, grow slowly, and may discharge in to the mouth giving a salty taste. Radiological examination shows a well-defined, rounded ovoid or occasionally heart-shaped defect in the anterior maxilla. Nasopalatine cysts must be distinguished from a normal large anterior palatine fossa which may be up to 7 mm in diameter, and from radicular cysts associated with the maxillary incisors. Desquamative gingivitis A fairly common problem in which the gingivae show chronic desquamation and is a term that denotes a particular clinical picture and not a diagnosis in itself. Most of these conditions are acquired, but a few are congenital with a strong hereditary predisposition, such as epidermolysis bullosa chemical damage, such as reactions to sodium lauryl sulphate in toothpastes allergic responses drugs psoriasis pyostomatitis vegetans. Most patients are seen only when vesicles and bullae have broken down to leave desquamation, and the clinical appearance is thus of erythematous gingivae, mainly labially, the erythema and loss of stippling extending apically from the gingival margins to the alveolar mucosae. The desquamation may vary from mild almost insignificant small patches to widespread erythema with a glazed appearance. In addition to a full history and examination, biopsy examination and histopathological and immunological investigations are frequently indicated. Conditions which should be excluded include: reactions to mouthwashes, chewing gum, medications and dental materials candidosis lupus erythematosus plasma cell gingivitis Crohn disease, sarcoidosis and orofacial granulomatosis leukaemias factitial (self-induced) lesions. The treatment of desquamative gingivitis consists of: Corticosteroid creams used overnight in a soft polythene splint may help.

Very ill babies may not tolerate feeding as gastric distension can cause diaphragmatic splinting. Over the last decade advances in neonatal care, including the increasing use of antenatal steroids, and early surfactant therapy, have modified a change in the underlying pathology in many cases. This definition does not have any grading of severity, and encompasses a wide spectrum of disease. Other treatments include; diuretics, corticosteroids, sildenafil, optimizing nutrition. Blood bypasses the liver via the ductus venosus and flows in to the inferior vena cava, and then the right atrium. This blood is then channeled to the left atrium and so to the left ventricle (via the foramen ovale). The right ventricle mostly receives deoxygenated blood from the superior vena cava. About 15% is pumped to the lungs and the rest is diverted, via the ductus arteriosus, to the descending aorta so that it can go to the placenta via the umbilical arteries. Postnatal circulation At birth, oxygen inhalation leads to pulmonary arterial vasodilatation, leading to d arterial resistance and i pulmonary blood flow. At the same time systemic vascular resistance i due to loss of the low resistance placental circulation. The foramen ovale closes as pulmonary venous return to left atrium i and right atrial pressure d. Echocardiography shows i pulmonary arterial pressure, large right to left shunt at the level of the foramen ovale and ductus arteriosus. There is wide variation in practice with some units treating many cases and others almost none. An approach considered sensible by many is: If asymptomatic Observe because most close spontaneously. Spina bifida Several types, all secondary to failure of midline fusion of dorsal vertebral bodies. There is a single central cerebral ventricular cavity with varying degrees of development and separation of the hemispheres. Neuronal migration defects Includes lissencephaly (smooth brain), pachygyria (very few gyri), polymicrogyria (numerous underdeveloped gyri), schizencephaly (deep cerebral cleft), neuronal heterotopia (foci of neurones in abnormal locations within the brain). All are associated with poor neurodevelopmental outcome and seizures, but eventual outcome is dependent on severity of malformation. An infant may have a range of symptoms and signs affecting: level of consciousness, muscle tone, posture, tendon reflexes, suck, heart rate and central nervous system homeostasis. Therapeutic hypothermia this is now the standard of care for term infants with moderate/severe hypoxic ischaemic encephalopathy. Haemorrhagic periventricular infarction may then occur secondary to impairment of cerebral venous drainage by intraventricular haemorrhage. Larger bleeds may present as sudden catastrophic systemic collapse, bulging fontanelle, neurological dysfunction. Prophylactic neonatal indometacin treatment reduces incidence, but does not improve long term neurodevelopmental outcome. Irrigation of lateral ventricles following surgical drain insertion is experimental. Blood in the lateral ventricles impairs adjacent venous drainage, which results in adjacent cerebral infarction. Typically a sporadic condition affecting preterm infants (790% of cases), but can be epidemic or occur in term infants. Severe intestinal necrosis is end result of an exaggerated immune response within the immature bowel leading to inflammation and tissue injury. If more extensive, two stage repair with bowel resection(s) and enterostomy, followed later by intestinal re-anastomosis. Excellent prognosis is seen in those who respond to medical treatment, but subsequent stricture may develop. Decisions on removing/ continuing to use any central catheter should be made by a senior doctor. Any ill newborn infants should have cultures taken and be treated with broad spectrum antibiotics that are effective against Group B streptococcus and other common neonatal pathogens. Well infants exposed to the above risk factors should be evaluated clinically and observed. Infants who remain well after this time are not at increased risk of disease in comparison with infants without risk factors. If there are multiple risk factors, or a previous child has been affected by Group B streptococcal sepsis many would consider blood culture and starting antibiotics appropriate. To reduce vertical transmission give hepatitis B vaccine to infant within 24hr of birth. To prevent infection from carers with cold sores, the lesions should be covered with a mask and the sores treated with topical aciclovir. In utero, the retinal vasculature develops in a relatively hypoxic environment, with vessels stimulated to grow towards the most hypoxic regions. It is therefore, essential to monitor and prevent hyperoxia in infants requiring supplemental O2. Treatment Diode laser treatment within 72hr (48hr if aggressive disease) of meeting any of the treatment criteria (see Box 6. Prognosis Almost all cases can be treated effectively so blindness is a rare outcome. London: Royal College of Ophthalmologists and British Association of Perinatal Medicine. Cause Chronic substrate deficiency-usually phosphate, rarely calcium or vitamin D. Orofacial clefts are due to failure of fusion of maxillary and pre-maxillary processes. Specialist nursing input, special feed devices and prosthetic plate (obdurator) may all be required if cleft palate is too large to allow adequate suck. Prognosis Repair of unilateral complete or incomplete lesions usually produces a good result. Volume to transfuse (mL) = desired rise in Hb (g/dL) x weight (kg) x [4 (packed cells) or 6 (whole blood)]. The condition is usually asymptomatic or only mild in the first affected pregnancy. Maternal blood group and rhesus antibody status are routinely checked in early pregnancy. Elevated or rising titres indicate that further foetal investigation is warranted. Toxic levels lead to selective damage of the cerebellum, basal ganglia, and brainstem auditory pathways. There is reduced resistance to bacterial infection, increased water loss, increased absorption of drugs (all more pronounced with prematurity. Nappy rash Usually a contact dermatitis from ammonia released by bacterial breakdown of urine. Erythema and scaling rash affects face, neck, behind ears, axillae, scalp (cradle cap), upper trunk, napkin area, and flexures. Minority will go on to develop atopic eczema, particularly if there is a family history. Withholding or withdrawing life-sustaining treatment must be first discussed with the parents. Time, rather than court proceedings, is usually the best approach, the latter being best reserved for extreme situations. Offer options of being present or holding the child in a private quiet room during withdrawal or afterwards.

An automated device to pierce the skin is preferred over a lancet, as it causes less pain and punctures to a predetermined depth, thereby reducing the risk of underlying bone damage or infection. Note that excessive squeezing leads to falsely high serum potassium and haematocrit levels, and bruising. Sometimes, necessity demands that other sites such as the scalp are used, particularly in infants. In infants this is often best done using your own gloved fingers or asking an assistant to squeeze the limb. Repeated gentle release and retightening of tourniquet often increases blood flow. Other suitable sites include the anatomical snuff box, volar aspect of forearm, great saphenous vein at the medial malleolus or knee. Whilst not ideal, scalp veins can be used, but the hair usually needs to be shaved. If possible, avoid larger veins if a percutaneous central line insertion is likely to be needed later. In an emergency, or if one or more normal sites have been used, scour the whole body and use whatever vein you can find! If the femoral artery is to be used in the older child, cannulation is preferable before sampling. Peripheral arterial cannulation this procedure is indicated when repeated arterial blood sampling or arterial pressure monitoring is required. The most common arteries used are those described for peripheral arterial blood sampling. Using the artery forceps as a guide, cut the umbilical cord horizontally and immediately below with the scalpel. Dilate the end of one of the arteries with fine forceps or a probe until wide enough for the catheter tip to be easily introduced.
