A prospective study was undertaken to determine the clinical pattern and outcome among children admitted with acute severe malaria into the emergency paediatric unit (EPU) at the Jos University Teaching Hospital (JUTH) over a 15-month period (between August 1991-October 1992). Five hundred and one (25%) children were admitted with acute severe malaria, out of a total of 2008 admissions into the EPU during the study period. Blood smears for malaria parasites were positive in 287 (57.7%) of the children and P. falciparum was the only species identified in the study. Seventy one percent of the children admitted were aged 5 years and below. Febrile convulsions was the commonest manifestation of acute severe malaria, accounting for 49.7% of the cases. Majority (97.8%) of the children responded satisfactorily to chloroquine therapy with clearance of parasitaemia. Associated bacteraemia was documented in 35 (7%) of the 501 children. Sixteen out of the 501 children died, giving a mortality of 3.2%. Cerebral malaria, which accounted for only 17.6% of the admissions, was responsible for 56.3% of all the deaths. Mortality was also associated with hypoglycaemia, severe anaemia, shock and repeated, prolonged seizures.

Human recombinant erythropoietin is used to treat chronic anemia in patients with end-stage renal failure. Erythropoietin causes hypertension, and hypertensive encephalopathy has been associated with its use. We describe six dialysis-dependent, chronic renal failure patients who developed hypertension, headache, and seizures while on erythropoietin. Four of the six patients had posterior white matter changes on neuroimaging. The encephalopathy was managed by prompt antihypertensive and anticonvulsant treatment and by discontinuation of erythropoietin. Hypertensive posterior leukoencephalopathy is associated with erythropoietin use.

This is a case report of a twenty-five years old man who developed, due to lead intoxication, a severe axonal peripheral predominantly motor neuropathy, after a shotgun injury. The projectile was retained in the right hip. Before this diagnosis had been done he was treated with corticosteroids in immunosuppressive doses and showed an improvement, but he had worsened at each attempt to interrupt the drug. Because he had also other signs of lead intoxication, such as abdominal cramps, severe anemia and seizures it was search for the blood levels of lead that was 101.2 micrograms/dl. The patient was treated with calcium disodium edetate and surgical removal of lead fragments. After that he had a good outcome with no need of corticosteroids. It is emphasized the possible relevance of the immune system on the mechanism of plumbic intoxication and the importance of the withdrawal of the lead material retained in joints.

A retrospective study compared the course of alcohol withdrawal, including delirium tremens, in women and men hospitalized in the Nowowiejski Hospital in Warsaw from 1973 to 1987. Medical records pertaining to 1179 patients were analyzed; 13.8% of these patients were women and 86.2% were men. The study showed that women began intensive alcohol drinking later than men (p < 0.0001), but the period between the onset of alcohol abuse and the first occurrence of alcohol withdrawal was shorter in women than in men (p < 0.0001). In the period of heavy drinking before hospitalization, women consumed significantly less alcohol then men (p < 0.0001); moreover, women drank nonbeverage alcohol less frequently than men (p < 0.05). Women were hospitalized substantially longer than men (p < 0.0001), whereas the duration of alcohol withdrawal symptoms at the time of hospitalization was comparable in both groups. Withdrawal seizures were significantly more frequent among men than among women (p < 0.001). Significant differences in the patients' somatic conditions were not noted between the groups, with the exception of anemia and decreased potassium concentration, which were more frequently observed in women (both p < 0.0001), and of increased concentration of ALT and hypoproteinemia, which were more frequent in men (respectively, p < 0.05 and p < 0.01). Co-existing personality disorders, depressive disorders, and anxiety disorders--as well as abuse of benzodiazepines and barbiturates--were more frequently observed in women (p < 0.0001). The period between the first hospitalization due to alcohol withdrawal and the time of death was significantly shorter in men than in women (p < 0.05). The results point to differences in the conditions and the course of alcohol dependence and alcohol withdrawal between women and men.

Three dogs became lethargic and had poor appetites within 2 months after anticonvulsant treatment was initiated to control seizures. Dogs were neutropenic, thrombocytopenic, and anemic and had splenomegaly. Sensitivity to phenobarbital and related anticonvulsants may induce life-threatening leukopenia, thrombocytopenia, and anemia in dogs. Phenobarbital-induced neutropenia in these 3 dogs may have posed a risk for developing bacteremia. It is important for clinicians to be aware of adverse effects so that adequate precautions can be taken. A baseline hemogram should always be obtained before starting anticonvulsant treatment, and periodic hemograms should be obtained to monitor animals. Furthermore, client education should include instructions on recognizing signs of bacteremia, thrombocytopenia, and anemia.

We report a 45-year-old man with monocytosis and right hemiparesis. The patient suffered from an acute myocardial infarction from which he recovered completely when he was 42 years old. One year prior to his death, he was found to have increase in monocyte count (35.5% of leukocytes) in peripheral blood and splenomegaly; he was admitted to the hematology service of our hospital. He was diagnosed as having chronic myelomonocytic leukemia after bone marrow examination. He was treated with radiation therapy with improvement in splenomegaly. In May of 1995, he had fever, anemia, and thrombocytopenia for which he needed daily blood transfusion. In November of 1995, he had an onset of weakness in his right hand, and neurologic consultation was asked for in November 27, 1995. Neurologic examination revealed a chronically ill japanese man in no acute distress. He was alert and not demented. Higher cerebral functions were intact. Cranial nerve examination revealed right facial paresis of the central type. Motor-wise, he was right hemiparetic. Generalized muscle wasting was noted apparently due to the chronic debilitating disease. Deep tendon reflexes were within normal range in the right upper extremity, but were diminished in other areas. Sensation was intact, and no meningeal signs were noted. Pertinent laboratory findings were as follows: Hb 8 g/dl, RBC 238 x 10(4)/microliter, WBC 2,900/microliter (band 1.0%, seg 18.5%, lym 28.0%, mono 44.0%, Baso 2.5%), Plt 13 x 10(4)/microliter, PT 16.6"/10.9", APTT 44.7"/35.0". CSF contained 87 mg/dl of protein, 155 mg/dl of glucose and 2 mononuclear cells/microliter. Bone marrow was slightly hypercellular with mild increase in blast forms. No chromosome abnormality was found. CT and MRI revealed a large mass in the left fronto-parietal region and the meninges showed marked thickening with enhancement after gadolinium-DTPA in MRI. The patient was treated with glycerol and steroid, but the subsequent course was complicated by a seizure, agitation, and pneumonia. He died from respiratory failure on January 13, 1996. The patient was discussed in a neurologic CPC and the chief discussant arrived at the conclusion that the patient had chronic myelomonocytic leukemia with infiltration of leukemic cells into meninges and the parenchyme of the cerebrum. Thickening of the dura was thought to be in part a reaction to the subdural hematoma as well as to leukemic cells along the meninges. Postmortem examination revealed hypercellular bone marrow with increase in monocytic cells (more than 20%). The lungs showed pneumonia with scattered old tuberculous lesions. The heart showed an old myocardial infarction in the posterior wall of the left ventricle. The brain showed an old chronic subdural hematoma in the left fronto-temporal region and a cystic mass lesion in the left frontoparietal region. The mass was hypercellular and most of them were monocytes. The dura mater showed reactive thickening without leukemic cell infiltration. It was concluded that this patient had chronic myelomonocytic leukemia with a formation of leukemic mass in the brain. Pathologists thought that the mass was a hematogenous spread. It is rare for chronic myelomonocytic leukemia to form a mass lesion in the brain.

A fetal heart rate tracing with absent variation and a sinusoidal pattern led to the diagnosis of acute fetomaternal hemorrhage at 29 + 2 weeks' gestation. The middle cerebral artery had increased peak blood flow velocity with reversed end-diastolic flow. Fetal coronary arteries visualized by color-coded and pulsed wave Doppler sonography showed slight decrease of time-averaged maximum velocities after oxygen administration, while cerebral flows remained unchanged. After administration of 50 ml blood (pre-transfusion hematocrit < 11%) the middle cerebral artery flow normalized and coronary artery velocities decreased further until coronary blood flow could no longer be visualized within 30 min of the transfusion (post-transfusion hematocrit 27%). Evidence of successful fetal resuscitation also included normalization of the fetal heart rate tracing and resumption of fetal activity (biophysical profile score 8/10). This was also observed after a second transfusion of 38 ml blood. Deterioration from repeated fetomaternal hemorrhage led to delivery of a severely anemic neonate (cord hematocrit 7%) by Cesarean section. Postnatally, a single seizure, moderate severity respiratory distress syndrome and grade III intraventricular hemorrhage were noted. Increased peak blood flow velocity with reversed end-diastolic flow may be observed in the middle cerebral artery of fetuses with acute anemia. Correction of this phenomenon with transfusion suggests that hypovolemia and low blood viscosity are major contributing factors. Furthermore, decreasing coronary artery blood flow velocities with supplemental oxygen and blood replacement confirm functional autoregulation of the fetal coronary circulation. Observation of these acute flow changes during fetal surveillance warrants investigation for a potentially serious underlying condition.

Six patients with severe and complicated falciparum malaria (6.7 +/- 2.7 WHO criteria) were admitted to our Intensive Care Unit. All patients acquired the disease while travelling in tropical Africa without appropriate chemoprophylaxis. The clinical manifestations included hyperpyrexia (all patients), chills (4), sweating (2), asthenia (3), anorexia (2), headache (1), arthralgias (1), vomiting (4), diarrhoea or abdominal discomfort (3), jaundice (2) and disturbances of consciousness (4). All patients had anemia, thrombocytopenia, hyponatremia, hypoproteinemia, hypoalbuminemia, hypocalcemia and acute renal failure, in one case associated with anuria. A low grade parasitemia was observed in two patients and a high grade parasitemia (20%-58% of erythrocytes) in four. Exchange transfusion was performed only in high parasitemic patients and all of them survived. All patients were treated with quinine, a sulfonamide and pyrimethamine. Additionally, five patients received oxytetracycline, doxycycline or clindamycin. Three patients required hemodyalisis. Five patients had delirium, coma or seizures. All patients had at least one sign of hepatic impairment: liver enlargement, jaundice or increased bilirubin or aminotransferase levels. Two patients had spleen enlargement. Laboratory findings suggested disseminated intravascular coagulation in four patients. Four patients developed pulmonary changes and three of them required mechanical ventilation. A Swan-Ganz catheter was placed in four patients. In three of them (two with pulmonary edema) the pulmonary capillary wedge pressure was initially increased, which suggested a cardiogenic or hypervolemia mechanism, but soon returned to normal level. One patient with low grade parasitemia died because of adult respiratory distress syndrome after 18 days. In our series, the degree of parasitemia was not related to the severity of the disease.

Falciparum malaria remains a major killer in developing countries, particularly for African children. The sequestration of parasitized erythrocytes in the deep microvasculature is mostly mediated by their cytoadherence to activated endothelium. Proinflammatory cytokines and particularly tumor necrosis factor contribute to severe disease but the pathophysiology of coma remains poorly understood. In young children, features of severe malaria include severe anemia, hypoglycemia and cerebral malaria. Half of the children with neurological impairment actually have raised intracranial pressure, and seizures are extremely common. Clinical respiratory distress usually reflects severe lactic acidosis. In non immune adults, pictures of severe sepsis with shock, acute renal failure and respiratory distress syndrome are common and often associated with bacterial coinfection. Although chemotherapy of malaria is challenged by the continuing evolution of antimalarial resistance, quinine remains the first-line drug for severe disease. The optimization of symptomatic management of severe malaria remains a major concern in developing countries.

We reviewed the case records of all children admitted to the Aga Khan University Hospital (AKUH) with a diagnosis of Haemolytic Uremic Syndrome (HUS) over a 7 year period (July, 1988-June, 1995). A total of 33 patients were admitted to the Pediatric ward at (AKUH) with a median age of 16 months (range 4 months-9 years). 97% cases identified were of the classic variety and no familial case was identified. The mean duration of illness was 27 days, 39% had an illness > 28 days. Diarrhoea and prior antibiotic used was in 97% patients. Oliguria at admission was seen in 52.5% and seizures in 24% of cases. Thrombocytopenia, anemia and leucocytosis at admission was present in > 72% of children. Hyponatremia was present in 42% while acidosis, hypocalcemia and hyperkalemia was seen in 30% of children. Despite optimal management and peritoneal dialysis in 14 (42%) patients, 8 (24%) died. No specific relationship was found between mortality and any clinical or laboratory feature at presentation. Our data highlights the importance of HUS in the Pediatric age group and the need for further studies to delineate risk factors for adverse outcome.
