A 22-year-old woman was admitted to hospital in shock, the admission diagnosis being lobar pneumonia with septic shock. Ultrasound demonstrated a tumour in the region of the left adrenal, but because of the absence of hypertensive symptoms and hypoglycaemia this was interpreted as a non-contributory finding. Despite intensive therapeutic measures the patient died within a few hours. At autopsy a phaeochromocytoma of the left adrenal gland was found. "Catecholamine myocarditis" resulting in acute cardiac failure, was demonstrated histologically. Phaeochromocytoma with predominant adrenaline or dopamine secretions often takes a normotensive or hypotensive course. Sudden excessive catecholamine release can, as in the described case, cause so-called adrenaline shock. The catecholamine-induced hypoxic-toxic myocardial changes determine the likely outcome.

An analysis of the features of lower respiratory diseases (LRD) associated with Respiratory Syncytial Virus (RSV) in 21 children aged 1-23 months, indicated that the clinical features did not differ appreciably from those described for LRD due to other infective agents. It was however, remarkable that none of the children was grossly malnourished, neither was there any death. The final respiratory diagnoses were bronchiolitis alone (6 cases), bronchopneumonia (6 cases), empyema/pleural effusion (3 cases, including one with bronchopneumonia), lobar pneumonia (3 cases, including one with associated bronchopneumonia). Streptococcus pneumonia and Klebsiella pneumoniae respectively, were isolated from blood culture in the two cases with lobar pneumonia alone. One child had laryngotracheobronchitis (croup) alone and another, croup associated with bronchiolitis and bronchopneumonia. Radiologically, the single most common lesion was patchy consolidation (8 cases) followed by hyper-inflation (6 cases); in one case, there was no observable lesion on the chest radiograph. All the 6 children who had bronchiolitis alone were aged 12 months and below, and were well nourished; conversely, 8 of the 12 children with pneumonia alone or in addition to other lesions and both children with pleural effusion, were older than 12 months and underweight. Other viral agents were identified in 8 (38%) of the cases. Complications included heart failure in 4 cases and a combination of anaemia and heart failure in one child with empyema. In a child with symptom complex and radiological features suggestive of acute obstructive lower respiratory infection with immunofluorescence evidence of RSV infection, age and nutritional status are important factors in determining the need for antibiotic therapy pending the outcome of bacterial cultures.

A prospective study of staphylococcal lower respiratory infection in 31 children aged 1-48 months has shown that radiologically, patchy consolidation was the single most common lesion, followed by pleural effusion with or without pneumothorax. Although the mean respiratory rate was 65/minute, it was below 50/minute in 8 cases. Complications include heart failure in 9 cases and severe anaemia necessitating blood transfusion in 9 others, seven (78%) of whom had pleural effusion. Finally diagnoses were bronchopneumonia alone in 16 (52%) cases, pyopneumothorax alone in 6 (19%), pyopneumothorax plus pneumonia in 5 (16%), pleural effusion in 2 (6%) cases and one case each of lobar pneumonia alone and a combination of lobar and bronchopneumonia. Staphylococcus aureus was isolated from the blood in 8 (62%) of 13 children with pleural effusion, indicating a need to consider parenteral antibiotic administration in the initial management of children with staphylococcal pleural effusion. Three (9.7%) patients died; they were all malnourished children who did not receive antibiotics prior to presentation; they all had bronchopneumonia, positive blood cultures and respiratory rates of 60/minute.

A 30-year-old man was admitted to our hospital for left lobar pneumonia with septic shock. Acute left-sided heart failure became evident as sepsis developed. Echocardiography revealed diffuse severe hypokinesis of the left ventricle (LV) and a pulmonary artery catheter showed Forrester subset II hemodynamics. Along with amelioration of sepsis and decrease of the serum concentrations of tumor necrosis factor-alpha and interleukin-6, LV hypokinesis improved. It is suggested that the patient's heart failure may have been due to functional depression of myocardial contractility resulting from a direct effect of the cytokines towards the cardiomyocytes, the so-called "septic myocardial depression".

A 24-year old booked primigravida, with rheumatic heart disease in heart failure and lobar pneumonia presented in active labour. She was stabilized and prepared for an emergency Caesarean section that was successfully managed with Epidural Anaesthesia. She was admitted into the intensive care unit where the pneumonia and heart failure were managed by the physicians. The importance of proper follow up and treatment and, the need to perform more epidural techniques to meet the ever increasing challenges to the Anaesthetist are highlighted.

Purulent pericarditis is an exceptionally rare complication of pneumococcal pneumonia in infants but a rapidly fatal disease if left untreated. A previously healthy 4-month-old boy presented at our emergency department with a 10-day history of fever and non-productive cough. No signs of heart failure or cardiac friction rub were evidenced. Chest radiography showed lobar pneumonia, right pleural effusion and cardiomegaly. Echocardiography revealed a massive pericardial effusion, and an emergency drainage was performed. Streptococcus pneumoniae grew up from purulent pericardial fluid and blood cultures. After intravenous antibiotherapy, the outcome was favourable. The introduction of the pneumococcal vaccine may favour an increase in the incidence of non-vaccine serotypes which most commonly cause empyaema and perhaps pericarditis. Therefore, pericarditis should always be considered a possible complication in patients with pneumococcal pneumonia and empyaema.

A previously healthy 60-year-old male presented with fever, general pain and a C-reactive protein (CRP) of 160 mg/L. He was prescribed doxycycline. In the emergency room three days later, he was intubated and had a saturation of 70% on 100% oxygen. The chest X-ray showed bilateral lobar pneumonia. Streptococcus pneumonia was later verified. As a Jehovah's Witness, he had refused blood transfusions, but accepted albumin. Two days after admission, veno-venous extracorporeal membrane oxygenation (V-V ECMO) was started and the patient was then transported on ECMO to Stockholm. After two days, echocardiography showed right cardiac failure and the patient had to be converted to veno-arterial ECMO (VV-A ECMO) by cannulation of the left femoral artery. The haemoglobin decreased from 10.0 to 6.0 g/dL. Iron, folic acid, and erythropoietin were administered to stimulate erythropoesis. Romiplostim, to stimulate the production of platelets, was also started immediately. Blood samples were reduced to a minimum. The ECMO circuit was changed twice, using saline for priming, and the blood in the old circuit was then given back to the patient. The haemoglobin concentration varied between 4.5 and 6.0 g/dL during the ECMO treatment and the platelets between 80 and 140 x10(9)/L. After 44 days on ECMO, the patient was weaned off ECMO with 50% oxygen and nitric oxide (NO) at 20ppm in the ventilator. Four days after decannulation, he was transferred to a nearby intensive care unit. Long-term ECMO treatment without transfusion of blood products is possible. Being a Jehovah's Witness should not automatically be a contraindication for ECMO.
