The association of tricuspid atresia and persistent truncus arteriosus is a very rare congenital anomaly. We report a newborn with a prenatal diagnosis of tricuspid atresia, in whom associated type II persistent truncus arteriosus was found by postnatal echocardiography. The patient had mild cyanosis and developed heart failure soon after birth. Balloon septostomy was performed to enlarge the interatrial communication. However, her condition rapidly deteriorated and she died of sepsis and heart failure at the age of 14 days.

There are three clinical presentations of anthrax in humans: cutaneous (>95% of cases), orogastric and inhalational. The infectious form, the spore, enters the body and is thought to germinate within macrophages either at the site of inoculation (cutaneous or orogastric) or in the regional lymph node (inhalational). The bacillus then synthesizes its antiphagocytic capsule and the lethal and oedema toxins which interfere with the non-specific host defences leading to the characteristic locally destructive lesion and spread by lymphatics to the systemic circulation and other organs. The cutaneous form begins as a papule which progresses over several days to a vesicle and then ulcerates. There is often oedema, sometimes massive, probably due to the oedema toxin that surrounds the lesions which then develop a characteristic black eschar. The patient may be febrile with mild to severe systemic symptoms of malaise, headache and toxicity. Oropharyngeal anthrax presents with severe sore throat or an ulcer in the oropharyngeal cavity associated with neck swelling, fever, toxicity and dysphagia. Gastrointestinal anthrax begins with anorexia, nausea, vomiting and abdominal pain which may be similar to an acute abdomen. There may be diarrhoea and ascites, both of which may be haemorrhagic. Inhalational anthrax begins with non-specific symptoms of malaise, fever, myalgia and non-productive cough. After a period of 2-3 days, this is followed by a sudden onset of severe respiratory distress associated with diaphoresis, cyanosis and increased chest pain. There may be a widened mediastinum and pleural effusions on chest X-ray. Death follows in 24-36 h from respiratory failure, sepsis and shock. The diagnosis of anthrax is easy if it is considered. The organism is readily observed by Gram or Wright stain in local lesions or blood smear and can be easily cultured from the blood and other body fluids. However, because of its rarity, it is not often included in the differential diagnosis and in inhalational disease the diagnosis is rarely made until the patient is moribund. More rapid diagnostic tests are under development. Penicillin, combined with supportive care, remains the mainstay of treatment, although the organism is susceptible in vitro to many antibiotics. In recent years, there have been significant advances in our knowledge of the organism and its toxins and it is anticipated that similar progress will be made in the future in developing more rapid diagnostic tests and new modalities of treatment.

Acute respiratory distress syndrome (ARDS) is the result of severe injuries of different etiologies of the capillary system in patients with previously healthy lungs, resulting in noncardiogenic pulmonary edema. The authors studied 42 infants in whom the histopathologic aspects were suggestive for ARDS. The etiologic factors of this syndrome were: severe gastroenteritis with hypovolemic or endotoxic shock (13 cases), sepsis (9 cases), fulminans purpura (2 cases), severe neurological disorders (13 cases), pulmonary infections (5 cases). In such conditions, if the infant presents hyperpnea followed by generalised cyanosis, refractory to oxygen therapy, and if there are clinical and radiologic signs of acute pulmonary edema, the diagnosis of ARDS must be considered and a complete intensive care therapy is compulsory in order to alleviate the severe prognosis of this syndrome.

Heart disease in infants and children may often lead to rapid decompensation. Early recognition by the primary physician is essential, since modern medicine and surgery can cure many heart defects. Main clinical signs are cyanosis, heart failure and/or abnormal auscultatory findings. Cyanosis appears shortly after birth or in small infants. In the newborn, cyanosis due to heart disease must be differentiated from pulmonary problems, sepsis or persistent pulmonary hypertension. Heart failure occurs more often in non cyanotic heart defects, mainly with left to right shunts. The main symptoms and signs of heart failure in the infant are briefly discussed. Abnormal auscultatory findings, usually murmurs, are the most common reason for referral to the paediatric cardiologist. However, most murmurs are "innocent" or "functional"; clues to their recognition are given. The present short review should help the primary physician to recognize signs of heart defects in infants and children so as to proceed with timely referral to the specialist.

Necrotizing cellulitis and fasciitis may be difficult to recognize. When skin necrosis is not obvious, the diagnosis must be suspected if there are signs of severe sepsis (accelerated heart or respiratory rates, oliguria, mental confusion.) and/or some of the following local symptoms or signs: severe spontaneous pain, indurated edema, bullae, cyanosis, skin pallor, absence of lymphangitis, skin hypoesthesia, crepitation, muscle weakness, foul smell of exudates. Many risk factors are suspected. A recent case-control study demonstrated that using ibuprofen increased the risk of cellulitis complicating chickenpox in children. Evidence is lower for other risk factors that are present with a high prevalence in most series: local lesion of skin or mucous membranes (acute or chronic disease, traumatism, surgery.), diabetes, arteriopathy, alcoholism, obesity, immunosuppression, NSAIDs. The risk of streptococcal necrotizing fasciitis is increased when in contact with patients infected by the same streptococcus.

This is a study of the venous gangrene of lower extremities and Staphylococcus aureus sepsis. We report on a premature infant who developed phlegmasia cerulea dolens (PCD) in both lower extremities in association with S. aureus sepsis, resulting in gangrene of the right foot. Non-pitting edema and cyanosis of the digits of the right lower extremity were noted 48 hours after hypotension and severe shock due to S. aureus sepsis. Intravenous antibiotics, isotonic fluids, and heparin were administered. Twenty-four hours later, edema and ischemic changes of the first and fifth left toes were also noted. Doppler flow study showed flow signals in both right and left popliteal arteries. However, there were no Doppler signals in neither right nor left popliteal vein. Emergency fasciotomies were performed on both lower limbs. The progression of the gangrene was limited to the right foot. There was complete resolution of PCD in both lower extremities. To the best of our knowledge, the association of S. aureus sepsis with PCD and venous gangrene in an infant has not been reported previously. This case illustrates the need for early recognition of PCD and aggressive intervention.

Severe lactic acidosis has been increasingly reported as a potentially fatal complication of HIV treatment. We report on an asymptomatic HIV-infected woman treated with stavudine, lamivudine and indinavir for one year. She was hospitalized because of progressive dispnoea, oedema, cyanosis and severe lactic acidosis. Arterial blood pH was 6.98, bicarbonate 4.4 mmol/l (normal value 22-26), blood lactate: 29.7 mmol/l (normal value <2.2). Hepatic function was normal. She had an impressively rapid response (within a few hours) to empirical treatment with thiamine (100 mg i.v.). No evidence of sepsis or malabsorption were identified and vitamin B1 level was not tested before thiamine infusion. Three months later she was re-started successfully on nelfinavir plus nevirapine. The rapid response to thiamine infusion deserves a careful attention and such an approach should be considered in similar cases as a support treatment of this potentially life-threatening complication of HIV therapy.

Transfusion-related acute lung injury (TRALI) is a second most serious complication of the blood transfusion. It is a group of symptoms and signs such as dyspnoea, hypotension, cyanosis, cough, elevated temperature, fever and lung oedema that usually develops within an hour or two after transfusion. The full stage clinical presentation is developed between 4th and 6th hours after transfusion. The syndrome is caused by leucoagglutinins or by other lymphocytotoxic antibodies specific for some antigens present on the donor's leukocytes. Alveoles of the lung are the main place of the pathological changes such as intra-alveolar oedema, haemorrhage, hyaline membrane formation, alveolar cell hypertrophy and scant interstitial inflammation. Chest X-ray showed bilateral pulmonary infiltrates but without vascular congestion and with normal cardiac silhouette comparing to the status before transfusion. The syndrome has to be distinquished from pulmonary oedema caused by acute cardial insufficiency, overhydration, trauma and sepsis.

Health workers should assess all children with a cough or difficult breathing for pneumonia. They should refer any child with severe pneumonia to a hospital for admission. At the hospital, a distinction is usually made between severe or very severe pneumonia among children 2 months to 5 years old. Signs or symptoms unique to very severe pneumonia are cyanosis and inability to drink. If a child has these signs and has convulsions, hospital personnel should consider a lumbar puncture to check for meningitis. Chest indrawing may also be present in very severe pneumonia cases. Chest indrawing in children with no cyanosis who are able to drink constitutes severe pneumonia. Health workers need to look for a variety of nonspecific signs of severe or very severe pneumonia in babies younger than 2 months: not feeding well, convulsions, abnormally sleepy, fever (38 degrees Celsius), fast breathing (=or+ 60 breast/minute), cyanosis, grunting, or apnea. These signs are also signs for meningitis or sepsis in young infants. Treatment for all 3 conditions is benzylpenicillin plus gentamicin for at least 14 days. Oxygen treatment is also indicated for these young infants. Treatment for both severe and very severe pneumonia cases includes oxygen and an antibiotic (benzylpenicillin and chloramphenicol, respectively). Hospitals should have in stock at all times essential antibiotics (benzylpenicillin, cloxacillin, chloramphenicol, and gentamicin) and an oxygen supply (oxygen cylinder or oxygen concentrator). When the oxygen supply is limited, children with very severe pneumonia should be the priority. Oxygen needs to be delivered at a flow rate of 1-2 liters/minute via nasal prongs or a nasal catheter. Admitted pneumonia cases with fever (39 degrees Celsius) should receive paracetamol to treat the fever. Hospital workers need to keep the airway of pneumonia cases clear and to encourage them to drink and/or breast feed.

Newborn infants may be transferred to a special care nursery because of conditions such as prematurity (gestation less than 37 weeks), prolonged resuscitation, respiratory distress, cyanosis, and jaundice, and for evaluation of neonatal sepsis. Newborn infants' core temperature should be kept above 36.4 degrees C (97.5 degrees F). Nutritional requirements are usually 100 to 120 kcal per kg per day to achieve an average weight gain of 150 to 200 g (5 to 7 oz) per week. Standard infant formulas containing 20 kcal per mL and maternal breast milk may be inadequate for premature infants, who require special formulas or fortifiers that provide a higher calorie content (up to 24 kcal per mL). Intravenous fluids should be given when infants are not being fed enterally, such as those with tachypnea greater than 60 breaths per minute. Hypoglycemia can be asymptomatic in large-for-gestational-age infants and infants of mothers who have diabetes. A hyperoxia test can be used to differentiate between pulmonary and cardiac causes of hypoxemia. The potential for neonatal sepsis increases with the presence of risk factors such as prolonged rupture of membranes and maternal colonization with group B streptococcus. Jaundice, especially on the first day of life, should be evaluated and treated. If the infant does not progressively improve in the special care nursery, transfer to a tertiary care unit may be necessary.
