Since the introduction of fenofibrate to European clinical practice in 1975, some 6.5 million patient-years of experience in the treatment of hyperlipidemia have been accumulated. A review of results of clinical trials shows fenofibrate to have a broad spectrum of lipid-lowering activity, reducing the total cholesterol level by 20-25% in type IIa patients and triglycerides by 40-60% in type IIb and IV patients. High levels of low-density lipoprotein cholesterol are reduced and, where low at baseline, high-density lipoprotein levels are increased. An associated activity is a 10-28% reduction in serum uric acid levels. Adverse reactions in the mostly open clinical trials ranged from 2-15%; mild gastrointestinal problems dominated, and occurred with much the same frequency in the placebo-treated groups of controlled trials. There are also reports of fatigue, headache, loss of libido, dizziness, and insomnia. Some excess of skin rash emerged as the only statistically significant unwanted clinical effect in one placebo-controlled trial. Biochemically, there are occasional fluctuations in serum transaminase values, while gamma-glucuronyl transferase and alkaline phosphatase are often decreased, all without apparent clinical significance. Lithogenicity of the bile is often increased above pretreatment levels, but there is no evidence from trials or postmarketing surveillance that the use of fenofibrate is associated with an increase of gallstone formation.

Data from 1,878 courses of intravenous ciprofloxacin therapy, administered to 1,869 patients in 59 clinical trials, were analyzed for drug safety. The 985 men and 884 women had a mean age of 50 years, and more than one third were over 60 years of age. An overwhelming majority had at least one accompanying systemic illness, and the condition of more than half the patients was only fair or poor at the onset of therapy. Ciprofloxacin was administered in a unit dose of either 200 mg (68 percent of the patients) or 300 mg (28 percent) by intravenous infusion, generally over 30 minutes every 12 hours, at a mean daily dosage of 456 mg. The duration of intravenous therapy ranged from one to 57 days, with a mean of seven days; over 1,000 patients were treated for more than five days. Adverse events considered probably or possibly related to intravenous ciprofloxacin were reported in 15.8 percent of the courses; therapy was discontinued prematurely in 3 percent. Local reactions at the site of infusion were the most common, occurring in 4.4 percent of the courses. Changes in blood chemistry values (4.1 percent) included increases in alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Reports of adverse effects referable to the gastrointestinal tract (3.0 percent) were primarily nausea and diarrhea. Central nervous system reactions (1.8 percent) included convulsive seizures, headache, and dizziness. In comparative trials, events considered probably or possibly drug related were reported for 17.3 and 13.6 percent of the ciprofloxacin- and ceftazidime-treated patients, respectively. The incidence of adverse events other than local reactions at the infusion site was not significantly different between the ciprofloxacin- and ceftazidime-treated patients (12.7 percent versus 11.0 percent, p greater than 0.2).

The therapeutic activity and tolerability of epomediol were studied in 28 patients with chronic hepatopathies. Treatment was continued, parenterally, for 10 days (400-600 mg once daily by intravenous infusion). Clinical parameters (headache, right hypochondrial pain, bitter taste in the mouth, asthenia and nausea) and hepatic function (transaminase, alkaline phosphatase and gamma-glutamyl transpeptidase) showed significant improvements. Clinical and systemic tolerabilities of epomediol were satisfactory.

We have evaluated the effects of dextrofenfluramine treatment on body weight control during a 90 day period, in obese patients on a calorie-restricted diet. The weight loss in dextrofenfluramine-treated patients was significantly higher than in placebo group. The rate of weight loss was linear up to the end of the trial in d-fenfluramine patients. Neural disturbances (vertigo, headache, depression) were the most frequent side effects observed in both the d-fenfluramine and in the placebo-treated groups, without significant differences between the groups. A total number of 23 patients in the dextrofenfluramine group and 20 patients in the placebo group complained side effects. Six patients (five in the d-fenfluramine group and one in the placebo group) discontinued the treatment, due to the side effects. No modifications of the biochemical parameters considered (fasting blood glucose, bilirubin, alkaline phosphatase, creatinine, blood cell counts, asparate-amino transferase (AST), alanine-amino transferase (ALT), total plasma and HDL cholesterol, and triglycerides) were observed at the end of the trial. A significant reduction of total serum cholesterol was observed in both groups at the end of the period of treatment. In conclusion, dextrafenfluramine was proved to be in short term trials an effective and safe tool in overweight control in obese patients.

Famotidine was compared to ranitidine in a short-term study on the treatment of duodenal ulcer. Famotidine 20 mg. b.i.d., 40 mg. b.i.d. and 40 mg. nocte heal as many ulcer as ranitidine (90.9%, 91.7%, 83.3% and 100% respectively). A single 20 mg. bedtime dose shows to be effective on preventing ulcer recurrence for as long as 48 weeks; the 38% recurrence rate observed with famotidine was statistically different from the 78% observed with placebo. Diarrhoea was the most common complain observed during the short-term trial, followed by sleepiness and headache. The few and small biochemical alterations during the long-term treatment (increase in transaminases, alkaline phosphatase, glucose, BUN) could in no instance be directly related to the substances on use.

The purpose of this pilot study was to determine whether daily administration of cyclosporin A to symptomatic patients with primary biliary cirrhosis for 1 yr would lead to a significant and sustained improvement in liver enzyme abnormalities. Twelve adult patients (11 female, 1 male; aged 52.6 +/- 8.9 yr, mean +/- SD) with serologic and histologically defined primary biliary cirrhosis were randomized to receive either oral cyclosporin A or vehicle placebo. Cyclosporin A was administered at sufficient dosages to maintain serum radioimmunoassay trough levels between 100 and 200 ng/ml (starting dosage, 2.5 mg/kg.day). After 1 yr of therapy, significant changes from pretreatment values were seen only in recipients of cyclosporin A. These included a 37% decrease in mean serum alkaline phosphatase and a 43% decrease in gamma-glutamyltransferase (controls +3% and -14%, respectively). Mean serum bilirubin and albumin levels and prothrombin times remained unaltered in the two groups, as did the extent of inflammation and fibrosis and the histologic staging of liver biopsy specimens. Although mean serum creatinine levels increased by 51% in recipients of cyclosporin A (+2% in controls), there were no associated changes in diastolic blood pressure or creatinine clearance values. Other side effects including thrombocytopenia, hirsutism, headaches, tremor, and parasthesiae were common in the treated group but not of sufficient severity to warrant adjustment in the dosage or discontinuation of therapy. The observed changes in hepatic, renal, and hematologic tests tended to return to baseline after discontinuation of therapy. Two patients, both placebo recipients, died of liver failure during the study period. The results of this study indicate that in symptomatic primary biliary cirrhosis, cyclosporin A administration is associated with a significant improvement in cholestatic liver enzyme abnormalities that persists for the duration of therapy. A progressive rise in serum creatinine levels and a high incidence of side effects raise concerns regarding the long-term safety of this agent in primary biliary cirrhosis.

A clinicopathological study was performed on 46 patients with chronic myeloproliferative diseases (CMPD) showing a thrombocythemia in excess of 1,000 x 10(9)/liter. When applying rigid diagnostic criteria only 23 patients were compatible with the initially suspected diagnosis of primary thrombocythemia (PTH). Comparison of PTH with the other entities of CMPD (CGL, 10, AMM, 6, and polycythemia, 7 cases) revealed a sustained elevation of the platelet count observable over a period of 2 to 8 years, no marked leukocytosis or abnormalities of the differential blood count, and a normal score of the leukocyte alkaline phosphatase. Episodes of hemorrhage and thrombosis as well as neurological symptoms (paresthesias, dizziness, headache), were encountered frequently as clinical manifestations in PTH. Survival time in PTH was significantly longer than in CGL with accompanying thrombocythemia. In a consecutively biopsied population of patients with CMPD, incidence of PTH was about 8%. In PTH the characteristic histopathology of the bone marrow consisted of an isolated (monolinear) proliferation of the megakaryocytes (density 127 +/- 47/mm2) without gross abnormalities of this cell lineage or a conspicuous increase in neutrophilic granulo- or erythrocytopoiesis. These lesions are significantly different from the morphological findings in the other CMPD with extreme thrombocytosis.

Health effects of occupational organophosphate exposure were investigated by subjecting 22 workers chronically exposed to an organophosphate pesticide, fenthion (O,O-dimethyl-O-(4-methylmercapto-3-methylphenyl)-phosphorothioate) to clinical evaluation, estimation of serum cholinesterase, serum alkaline phosphatase (SAP), serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT). The mean age of the workers was 31 years and the mean duration of fenthion exposure 8.2 years. Headache (59%), giddiness (50%), ocular symptoms (27%) and paresthesia (18%) were the commonest symptoms. Serum acetylcholinesterase and butyrylcholinesterase levels were significantly lower than in controls. After withdrawing the workers from organophosphate exposure for 3 weeks, the follow-up study revealed absence of transient symptoms. There was no change in their neurological status, and serum acetylcholinesterase and butyrylcholinesterase levels were raised significantly, whereas the other serum enzymes showed no significant change. For monitoring of occupational organophosphate exposure, the importance of both clinical and biochemical parameters is emphasised.

A case of ossifying fibroma of the cranial vault is described. Several reports emphasized the rare existence of this lesion limiting in the cranial vault. The patient was a 76-year-old woman who suffered mild headache in the parietal region after a trivial head trauma. Physical and neurological examination were normal. Plain skull X-P revealed irregularly bordered, 4 X 4 cm sized radiolucent area in the left temporal bone. The bone scintigraphy using 99mTc-MDP showed an abnormal uptake like a doughnut. Levels of serum P, Ca and alkaline phosphatase were within normal range. A tumor was softer than normal skull, and undertaken piecemeal removal. The dura was normal. After the total removal of the tumor, cranioplasty using Resin plate was performed. Microscopically the lesion was composed immature, irregular spicules of bone and fibrous tissue. Abundant fibroblasts were arranged in a random fashion in the stroma. Characteristically, the spicules of bone surrounded by rimming of osteoblasts. Ossifying fibroma is a benign fibroosseous tumor. Although this tumor is typically found in the maxillary sinus and mandible, it has also been reported in the paranasal sinuses, frontal, ethmoid, sphenoid bone and orbital roof of the young adult. But previously reported cases involving the cranial vault alone were only 7 cases. Etiology of ossifying fibroma is almost unknown.

Cefmenoxime was evaluated in an open trial consisting of 41 patients. Forty infections in 36 patients could be evaluated. Thirteen patients had pyelonephritis due to Escherichia coli (two bacteremic), Pseudomonas aeruginosa, Klebsiella pneumoniae, or Streptococcus faecalis; all improved and 12 of 13 were clinically cured, but one relapse (S. faecalis) occurred at two weeks. Six patients with cystitis due to E. coli, Citrobacter freundii, Serratia marcescens, P. aeruginosa, or S. faecalis all improved, but relapse or reinfection, or both, occurred in five due to P. aeruginosa, S. faecalis, C. fruendii, or E. coli. Neurogenic bladder or other complications were present in five of 13 patients with pyelonephritis and five of six with cystitis. Ten patients with pneumonia and one with tracheobronchitis due to Hemophilus influenzae, S. pneumoniae, S. agalactiae, or Neisseria meningitidis all improved and seven had resolution without relapse, but P. aeruginosa emerged in two patients, one of whom died. Eight soft tissue infections due to Staphylococcus aureus, Peptococcus prevotti, Streptococcus species, or infections of mixed origin resolved in six. Sterility of blood cultures was obtained in one patient with endocarditis due to S. anginosus, but other therapy was substituted. Clinical resolution of the toxic shock syndrome and subsequent negative endocervical cultures for S. aureus occurred in one. Granulocytopenia of unverified cause in four (with less than 1,500 mm3) and two (with less than 2,000 mm3) was reversible. Headache during treatment occurred in six patients and a possible disulfiram-like effect in three. Elevations of serum glutamic oxalacetic transaminase and alkaline phosphatase occurred in five, Coombs' positivity in two, and diarrhea in three. Clinical efficacy of cefmenoxime was significant. Possible side effects require further study.
