An outbreak of severe haemorrhagic illness began in the municipality of Guanarito, Portuguesa State, Venezuela, in September, 1989. Subsequent detailed study of 15 cases confirmed the presence of a new viral disease, designated Venezuelan haemorrhagic fever. Characteristic features are fever, toxicity, headache, arthralgia, diarrhoea, conjunctivitis, pharyngitis, leucopenia, thrombocytopenia, and haemorrhagic manifestations. Other features include facial oedema, cervical lymphadenopathy, nausea/vomiting, cough, chest or abdominal pain, and convulsions. The patients ranged in age from 6 to 54 years; all were residents of rural areas in central Venezuela, and 9 died. Infection with Guanarito virus, a newly recognised arenavirus, was shown by direct culture or by serological confirmation in all cases. Epidemiological studies suggest that the disease is endemic in some rural areas of central Venezuela and that it is rodent-borne. Venezuelan haemorrhagic fever has many similarities to Lassa fever and to the arenavirus haemorrhagic fevers that occur in Argentina and Bolivia.

A 2.5-year retrospective study of pyogenic meningitis in hospitalized children in Kelantan was carried out with regard to aetiology, clinical features, investigation, treatment and outcome. There were 58 children with 43 cases (74.1%) occurring below the age of 1 year. Frequent presenting symptoms included fever (98.3%), fits (77.6%), anorexia (39.7%), vomiting (34.5%) and drowsiness (12.1%). On admission, 37 (63.7%) had neck stiffness, 10 (17.2%) had Kernig's sign and 32 (55.2%) had coma. CSF cultures were positive for Haemophilus influenzae in 29 (50%), Streptococcus pneumonia in 13 (22.4%) and Neisseria meningitidis in 3 (5.2%). The antibiotic sensitivity profiles showed that the three main organisms were 100% sensitive to Chloramphenicol, Streptococcus pneumoniae was 100% sensitive to penicillin, Neisseria meningitidis was 100% sensitive to penicillin and ampicillin, and Haemophilus influenzae was 90% sensitive to penicillin and ampicillin. The total hospital mortality was 18.9%. All but two of the eleven deaths occurred in children younger than 1 year. Nineteen of the 35 (54.3%) survivors attended for at least one follow-up after discharge from hospital. Of these 19 children, 47.4% had neurological sequelae.

The clinical presentation and laboratory features in relation to short-term outcome in 118 prospectively studied Sudanese children who were admitted with meningococcal (MC) meningitis and/or septicaemia during the 1988 group A MC epidemic in Greater Khartoum are described. Their ages ranged from 25 days to 15 years (mean: 78 months) and 42% were less than 5 years old. The male:female ratio was 1.6:1. Forty (34%) came from one of the peri-urban shanty towns encircling Greater Khartoum. A history of MC immunization (A and C vaccine) was obtained in 22%, but only five children (4.8%) had the vaccine between 4 weeks and 1 year before their illness. The commonest symptoms on admission were vomiting, neck rigidity and diarrhoea. Convulsions were significantly more frequent in children under 5 years old (p = 0.0005). Fifty-six (47%) had evidence of malnutrition. In descending order, fever, neck stiffness and Kernig's sign were the most commonly observed signs, the latter two being significantly more often detected in children older than 1 year. Twenty-four patients 20%) had disturbed consciousness. The case fatality rate was 6.3% and this was significantly higher in those presenting with meningococcal septicaemia (p = 0.0006). Other significant associations with mortality were short duration (less than 1 day) of symptoms (p = 0.0006) and clinical shock detected on admission p = 0.003). Transient complications were infrequent and permanent neurological sequelae were confined to bilateral profound sensorineural hearing loss in three children (2.9%) and hemiplegia in two 1.9%.(ABSTRACT TRUNCATED AT 250 WORDS)

Accidental kerosene ingestion continues to cause morbidity and mortality in third world countries, where kerosene is still used for cooking, heating and cleaning. In this prospective study, 78 children aged from 10 months to 5 years were managed at Makassed Hospital in Jerusalem for kerosene ingestion. Respiratory distress developed in 60 (76.90%) children. Two who required mechanical ventilation died. Vomiting, which occurred in 49 cases, did not seem to increase the risk of respiratory complications, suggesting that aspiration occurs with the initial ingestion. Chest X-ray changes were noted in 60% of the children on admission. Pleural effusions occurred in three cases over 24 hours after the incident. CNS manifestations, most likely caused by anoxia, were seen in 27% of the children, but in only two were they severe in the form of convulsions, and both died. Fever occurred in about 50% of the children during their stay in hospital. Severe gastric dilatation developed in the four most severely ill children, two of whom died. The quantity of kerosene ingested by them was estimated to be large.

A 48-year-old female suffered from severe headache, vomiting, and disturbance of consciousness. On admission, she was somnolent with mild paresis of the left leg. Precontrast computed tomography (CT) scans showed a high-density area in the left sylvian fissure and the posterior horn of the left lateral ventricle. Angiographically, a right middle cerebral artery aneurysm and a basilar artery aneurysm were recognized. Furthermore, on the venous phase of bilateral carotid angiograms, superior sagittal sinus (SSS) thrombosis was recognized. Subarachnoid hemorrhage (SAH) was probably induced by rupture of a dilated vein associated with SSS thrombosis, because high-density area on CT scan and location of the aneurysms were different. The patient was initially treated conservatively. Two months later, craniotomy was performed which did not disclose any trace of hemorrhage around the aneurysms and aneurysms themselves. Postoperatively, acute brain swelling and generalized convulsion were induced. The patient became ambulatory 5 months after surgery. In SAH cases, the venous phase should be examined at least in one side of the carotid arteries. In such a SAH case induced by venous thrombosis complicated by aneurysms it is very difficult to decide the timing of surgery for aneurysms.

Combination chemotherapy with Cyclophosphamide, Adriamycin and Cisplatin (CAP) is one of the most effective chemotherapies for ovarian cancer. Severe vomiting induced by this treatment may cause a disorder of the serum electrolytes. Severe hyponatremia was observed in one patient who complained of convulsions and unconsciousness. Accordingly we studied the disorder of serum electrolytes in 158 courses of CAP treatment (44 patients) during the five years from 1984 to 1988. The serum electrolytes were influenced by the amount of vomiting in this study. Consequently frequent examination of serum electrolytes is necessary during this treatment.

Clinical profile of pyogenic meningitis was studied in 256 cases over a period of 8 years. The male to female ratio was 1.46: 1 and 83.6% of the patients were less than 3 years of age. Fever, altered sensorium, refusal to feed, convulsions and vomiting were the common presenting symptoms. Six (2.3%) of them had subnormal temperature and the sensorium was normal in 12.5% of cases. Cerebrospinal fluid was clear in 9.4%, cell count was less than 100/cmm in 8.2%, sugar was more than 40 mg% in 24.2% and protein was less than 50 mg% in 12.5% of cases. Diplococcus pneumoniae was the commonest causative agent. The overall mortality was 30.5%. It is concluded that young children suffering from this disease may not have the typical features and one should have the highest suspicion to make an early diagnosis so that the morbidity and mortality from this condition can be reduced.

A female patient who had clinical characteristics of MELAS but with no apparent muscle symptoms was reported. She was in good health until 12 years and 5 months of age when she began to have afebrile generalized tonic-clonic convulsions. Thereafter, she had repeated stroke-like episodes, including headache, vomiting, convulsions, hemiparesis and left ehemianopsia. She had neither muscle weakness, fatigability nor atrophy. Laboratory examinations disclosed elevated lactate and pyruvate levels in the serum and cerebrospinal fluids, transient focal low density areas on brain CT and right sensorineural deafness by audiometry. No ragged-red fibers (RRF) were found in the first biopsy at 13 years and 6 months of age, and two RRF-like fibers containing red granular materials in the subsarcolemnal regions in the second at 15 years and 3 months of age. A biochemical assay on the two biopsied muscles demonstrated normal enzyme activities in the mitochondrial electron transport system. She was diagnosed as having MELAS because of remarkable mitochondrial abnormalities in smooth muscle cells in the intramuscular arterioles which were clearly demonstrated by succinic dehydrogenase (SDH) stain and on electron microscopy. It was suggested that the stroke-like episodes in this patient were induced by a preferential damage to the mitochondria in the blood vessel walls. Thus, we conclude that a simple method of identifying the strongly SDH-reactive blood vessels (SSV) in frozen sections is critical in supporting or making diagnosis of MELAS.

The clinical manifestations observed in 102 malaria patients (parasitaemia of over 8,000 Plasmodium falciparum/mm3) hospitalized in 1989 in Brazzaville (Congo) were analyzed after ruling out the cases of pernicious malaria. The clinical picture was fever, stomach upset with headache and musculo-articular pain as in classical cases. In children these manifestations were frequently associated with convulsions. Diarrhoea was not uncommon in young children. Vomiting was frequent in both children and adults. Splenomegaly and hepatomegaly were closely related to age. In these subjects, chemoprophylaxis was rare in children, practically non-existent in those aged over 5 years. However, presumptive treatment and self medication was usual regardless of age.

Twenty five idiopathic epileptic children with occipital electroencephalographic (EEG) foci have been studied for more than 3 years clinically as well as electroencephalographically. They were categorized into two groups, i.e., those with (A group) and without (B group) visual symptoms. Not only visual symptoms, but also headache, nausea, vomiting or generalized tonic clonic convulsion (GTC) were observed in group A. GTC or tonic deviation of the eyes were observed in group B. Migrainous symptoms were present in 3 cases of group A. Interictal EEGs consisted of spikes or spike and wave complexes in the occipital area. In some cases epileptic foci existed not only in the occipital area, but also in other regions. The mean age of the onset of the clinical symptoms was 8 in group A and 5 in group B. Beyond the age of 15, the abnormal EEGs were observed in 80% of the cases in group A, and in 18% of the cases in group B. The symptoms disappeared by 9 years of age in 92% of the cases in group B, and by 15 years of age in 82% of the cases in group A. From these results the prognosis of idiopathic epilepsy of childhood with occipital EEG foci was considered as good.
