A life-threatening complication due to pulmonary haemorrhage following hump-nosed viper bite.

BACKGROUND: Hump-nosed viper bite, the commonest venomous snake bite in Sri Lanka, is associated with significant morbidity. Specific anti-venom is not available for hump-nosed viper envenomation which is usually managed with supportive treatment. Pulmonary haemorrhage is an unusual manifestation of hump-nosed viper bite. Here we present a case of hump-nosed viper envenomation which complicated by pulmonary haemorrhage and was successfully treated with systemic steroids. To the best of our knowledge, it has not been reported in the literature before. CASE PRESENTATION: A previously healthy 55-year-old man presented to the local hospital 18 h after a hump-nosed viper bite. He developed bilateral severe pulmonary haemorrhages, evidenced by rapid desaturation which needed intubation and mechanical ventilation, bleeding from the endotracheal tube and bilateral alveolar shadows in a chest x-ray. He had no other bleeding manifestations. Because of the life-threatening situation, he was treated with methylprednisolone pulse therapy. There was a rapid improvement of hypoxia with a resolution of x-ray changes. He was successfully weaned off from the ventilation after 24 h. CONCLUSION: This case highlights the importance of suspecting pulmonary haemorrhage in a patient who develops desaturation and alveolar shadow following hump-nosed viper bite even in the absence of other bleeding manifestation. Early and timely treatment with systemic steroid can be lifesaving in such patients.

Clozapine induced pancytopenia leading to severe sepsis: an unusual early complication.

BACKGROUND: Clozapine is a second generation antipsychotic used to treat resistant schizophrenia and other psychotic illnesses. Leucopenia or agranulocytosis is a rare side effect of this drug. Pancytopenia is an extremely rare side effect of clozapine and literature review showed only one such case in where the pancytopenia developed several months after starting clozapine together with other antipsychotic drugs. CASE PRESENTATION: A 26-year-old Sri Lankan male was admitted with fever for 3 days. Apart from generalized body aches there were no other significant symptoms. His blood counts showed pancytopenia. He was being treated for a resistant schizophrenia and clozapine was started only 4 weeks before. Common causes for pancytopenia were excluded, and a diagnosis of clozapine induced pancytopenia was made. He was managed in the intensive care unit with broad spectrum antibiotics, antifungals and granulocyte colony stimulating factors. He made a complete recovery after 4 weeks. CONCLUSION: This is a rare and probably the first reported case of early onset clozapine induced pancytopenia complicated by severe sepsis recovering completely.

Bilateral posterior fracture-dislocation of the shoulders following epileptic seizures: a case report and review of the literature.

BACKGROUND: Bilateral posterior fracture-dislocation of the shoulders is an uncommon complication of grand mal seizures. We report a case of bilateral posterior dislocation of the shoulders with proximal humeral fractures following epileptic seizures. A posterior fracture-dislocation of the shoulder is very rare and can be caused by epileptic seizures, trauma, electrocution or electroconvulsive therapy. CASE PRESENTATION: A 62-year-old Sri Lankan male was admitted to our medical unit following four repeated generalized tonic-clonic convulsions, each lasting for several minutes. Following the second seizure he reported an inability to move both upper arms due to intense pain. There was no history of fall during the episodes of convulsions however but the bystanders have forcibly restrained his movements during the tonic-clonic convulsions. Clinical examination revealed severely restricted range of movement in both shoulders, with associated swelling and bruising of the shoulder joints and upper arms. Radiographs of the shoulders confirmed fractures at the level of surgical neck with posterior dislocation. CONCLUSION: Bilateral posterior fracture-dislocation of shoulders complicating epileptic seizures are rare. Forcible restraining of the patient's upper limbs during seizures is the likely cause for the fracture dislocations in our patient and this had not been reported before.

Myocarditis causing severe heart failure--an unusual early manifestation of leptospirosis: a case report.

BACKGROUND: Leptospirosis is the most widespread zoonosis in the world. Cardiac involvement is a frequent complication of leptospirosis although significant left ventricular dysfunction is rare. We report a case of fatal leptospira myocarditis leading to cardiogenic shock on the second day of illness. This early occurrence of myocarditis is not previously reported. CASE PRESENTATION: A 36-yr-old previously healthy Sri Lankan male who takes care of a horse presented to the medical casualty ward with a one day history of fever, arthralgia and severe myalgia. He developed hypotension on the second day of illness. Electrocardiogram showed sinus tachycardia with ST segment depression in lateral leads which evolved in to rapid atrial fibrillation in the subsequent days. 2D echocardiogram showed dilated cardiac chambers with severe global hypokinesia and an ejection fraction of 20%. His renal and liver functions were within normal limits. He developed multi organ dysfunction syndrome and refractory shock, later in the course of illness. Leptospirosis was confirmed by positive leptospira IgM and negative IgG. Patient died on the fifth day of illness despite optimal medical treatment with intravenous penicillin, meropenem, levofloxacin, inotropes and supportive care in the intensive care unit. CONCLUSIONS: We describe a rare and unusual early complication of leptospirosis which has not been reported before. It is important to bear in mind that leptospirosis could present as myocarditis during the early phase of illness.
