Overnight metabolic studies in 39 poorly controlled insulin-treated diabetic patients aged 9 to 66 years showed hypoglycaemia (blood-glucose less than 2 mmol/1) in 22 patients; it lasted 3 h or more in 17. Hypoglycaemic symptoms were very mild or absent, but 19 patients had other features of overtreatment with insulin. These included lethargy, depression, night sweats, morning headaches, fits (3 patients), glycogen-laden hepatomegaly (3), and acquired tolerance to high doses of insulin (mean 1 u/kg/24 h). The best clinical clue to recurrent nocturnal hypoglycaemia was the intermittent occurrence of symptoms, however "mild" and infrequent these appeared to be. Reduction of insulin by a mean of 25% in these patients (without change of species) did not result in loss of overall control; 1 patient with recurrent ketoacidosis was stablished on 40% of his initial dose. It is difficult, sometimes impossible, to achieve good overnight control with conventional once or twice daily insulin therapy. Since patients readily become tolerant of low blood-glucose levels, reliance on urine tests and symptoms of hypoglycaemia as a guide to dosage easily produces a spiral of overtreatment.

Clinical observations were made on 95 serologically or virologically confirmed dengue fever cases during an epidemic in a rural area of Indonesia in December 1976. The age distribution was similar to that observed in patients with dengue hemorrhagic fever in Jakarta, a highly endemic urban area. The observed disease ranged in severity from undifferentiated fever to shock and death. The majority of patients had acute onset of fever with nausea, vomiting, headache, and abdominal pain. Hepatomegaly was observed in only 19% of the patients. A positive tourniquet test was the most frequently observed hemorrhagic manifestation, but epistaxis was observed in 20% and hematemesis in 6% of the patients. Dengue shock syndrome was observed in 37% of the patients. There were four deaths, three of which were confirmed as due to dengue infection by virus isolation. The data suggest that one, and possibly two, of the fatal cases with virus isolation were primary infections, based on the results of hemagglutination-inhibition test using all four dengue antigens.

We have recorded clues to the clinical recognition of chronic insulin overdosage in 101 pediatric patients with diabetes mellitus, identified predisposing circumstances, and reconsidered the traditional strategy of slow reduction in insulin dose. Overtreatment occurred in 70%, overall, and in 90% of those referred for instability; mean overdose was 38% of the readjusted dose. The most common findings were frank hypoglycemic episodes, polyuria/nocturia/enuresis despite increasing insulin dosage, excessive appetite, hepatomegaly, weight gain, headaches, exercise intolerance, marked variation in glucosuria, mood swings, and frequence bouts of rapidly developing ketoacidosis. Overtreatment usually developed because of attempts to achieve metabolic control using glucosuria as principal criterion. One fourth of those observed became overtreated during periods of emotional turmoil when need for increased insulin to counter stress-induced hyperglycemia and ketosis led to chronic increase in dosage. Persistent glucosuria/ketonuria and exacerbation of hypoglycemic symptoms were more frequent with slow than with rapid reduction in insulin dosage.

Twenty-four cases of dengue haemorrhagic fever/dengue shock syndrome were studied in Delhi in the months of September and October, 1988. The majority of these cases were boys aged 6-10 years. Classical symptoms of dengue (fever, headache, aesthesia, myalgia) occurred in all the patients. Digestive symptoms (nausea, vomiting, anorexia, abdominal pain and hepatomegaly) were also common. Haemorrhagic manifestations were present in 41.7% of the cases. Of these, 90% had gastrointestinal haemorrhages. Shock occurred in 17 cases (70.8%). Thrombocytopenia and prolongation of coagulation profile were found in 62.5% of cases. Three patients (12.5%) who presented with encephalopathy died. The other 21 patients recovered after an average period of 2-8 days.

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.

In this study we examined the clinical and laboratory findings of 80 in-patients. There is an important difference between sexes (p greater than 0.05). Comparison of ages showed that 7-30 age is more vulnerable than the older group. We found clinical symptoms of fever, chills, headache, abdominal pain, disturbances in bowel function, nausea, vomiting, anorexia, and lassitude in the first two weeks more frequently when compared with the 3rd, 4th, 5th weeks of illness (p less than 0.001). Where physical finding of rose spots, discordant pulse rate are important in the first two weeks (p less than 0.001). Abdominal discomfort is an important symptom both in the first two and in the last three weeks (% 40.3 and % 36 respectively). Hepatomegaly and splenomegaly, were found more frequently in the last three weeks. According to laboratory findings of anemia, leukopenia, increased erythrocyte sedimentation rate and positive blood and feces cultures there is no important difference between the first two and last three weeks (p greater than 0.05). Increase in polynuclear leucocytes is important for the first two weeks, and increase in lymphocytes is important in the last three weeks (p less than 0.001). Positivity of group agglutination tests is 57%, in the first two weeks and 83% in the last three weeks. This difference is found to be important.

Fenofibrate is a lipid-regulating drug which is structurally related to other fibric acid derivatives, such as clofibrate. At the recommended dosage of 200 to 400 mg daily, it produces substantial reductions in plasma triglyceride levels in hypertriglyceridaemic patients and in plasma total cholesterol levels in hypercholesterolaemic patients. High density lipoprotein (HDL)-cholesterol levels are generally increased in patients with low pretreatment values. Fenofibrate appears to be equally effective in diabetic patients with hyperlipoproteinaemia without adversely affecting glycaemic control. The influence of fenofibrate on the plasma lipid profile is sustained during long term (2 to 7 years) treatment. Comparative studies conducted to date have involved only small groups of patients--in overall terms fenofibrate was at least as effective as other fibrates, but larger comparative studies are needed before valid conclusions on its relative efficacy compared with nonfibrate lipid-lowering drugs can be drawn. The influence of fenofibrate on morbidity and mortality from cardiovascular disease has not been studied. Clinical adverse reactions to fenofibrate have mainly consisted of gastrointestinal disturbances, headache and muscle cramps. Transient elevations in transaminase and creatine phosphokinase levels commonly occur. Isolated cases of hepatitis with substantially elevated transaminase levels have been reported. Fenofibrate induces hepatomegaly, peroxisome proliferation and hepatic carcinomas in rodents, but this type of hepatotoxicity has not been observed in humans. The biliary lithogenic index is increased by fenofibrate, but this has not been shown to have increased the incidence of gallstones in treated patients. Thus, fenofibrate offers an effective and well tolerated alternative to clofibrate or other fibric acid derivatives, but its relative efficacy and tolerability compared with other types of lipid-lowering drugs, and its effect on cardiovascular morbidity and mortality, remain to be clarified.

Fifteen Thai children, diagnosed with dengue hemorrhagic fever and admitted to the Children's Hospital in Bangkok, were studied. All cases were serologically proved to be secondary dengue infections. The clinical signs and symptoms in the first few days of the acute febrile phase were similar to those observed in cases with classical dengue fever, and included continuously high fever, headache, muscle pain, nausea, vomiting and abdominal pain, etc. In the laboratory findings we noted hypoalbuminemia and mild elevation of the GOT and GPT. The hemogram showed an increasing atypical lymphocyte count during the acute febrile period. Prolongations of the partial thromboplastin time and thrombin time were also found, especially in the severe shock cases. All patients had varying degrees of hepatomegaly and pleural effusion from their chest x-rays accompanied by a rapid increase in the hematocrit of more than 20% and a fall in the platelet count to less than 100000/microliters. During the plasma leakage period the patients easily developed shock, even leading to death, unless adequate fluid supplies were given. This is also the major pathophysiological difference between dengue hemorrhagic fever and classical dengue fever. Although some studies concerning the pathogenesis of dengue hemorrhagic fever have been reported, but the exact mechanisms need further investigation.

A study of morbidity and side effects of treatment with praziquantel in relation to intensity of infection with Schistosoma mansoni was conducted in 406 infected individuals from a newly-settled village in Metekel, north-western Ethiopia. Each subject was submitted to a standardized medical history and abdominal palpation. The frequencies of hepatomegaly and splenomegaly were low, 2% and 3%, respectively. A positive association was found between egg load and a history of blood in the stool. Interviews on side effects were conducted on the day following treatment with praziquantel (40 mg/kg body weight). Positive correlations with egg load were found for several side effects, including abdominal pain, diarrhoea, headache, back pain, and vomiting. Unusual side effects involving swelling of various parts of the body confirm 2 previous reports from a different region in Ethiopia and should be investigated further.

Mediterranean Spotted Fever is a disease caused by Rickettsia conorii. It is endemic to the Mediterranean area, where, for the last few years, the number of cases has increased, possibly due, in part, to climatic factors. The main clinical aspects of a prospective series of 246 cases diagnosed from 1983 to 1988 are presented. The most characteristic manifestations were fever, exanthema and tache noire. Other frequent manifestations were headache, myalgia and arthralgia, and with lesser frequency, hepatomegaly, splenomegaly, gastrointestinal symptoms and conjunctivitis. Notable analytical changes are the rise of hepatic and muscular enzymes in a large number of patients. In some cases we have found signs of myositis in muscular biopsy. The evolution of our patients was usually favorable though serious and even deadly forms of the disease have been described. One of the factors that seems to greatly influence the appearance of these forms is delay in the initiation of effective treatment.
