The efficacy of halofantrine in the treatment of acute malaria in nonimmune travelers.

A multicenter prospective trial was performed to investigate the efficacy and the tolerability of halofantrine in nonimmune patients with malaria imported from areas with drug-resistant falciparum parasites (mainly Africa). Forty-five of the 74 subjects were treated with a one-day regimen (3 x 500 mg) of halofantrine, and the other 29 received the same regimen with an additional treatment on day 7. In the second group, a 100% efficacy rate was demonstrated, but in the group receiving the one-day regimen, four recrudescences were observed in patients with falciparum malaria. Only five mild adverse reactions were seen, which disappeared spontaneously after the end of the treatment. We conclude that halofantrine is highly effective in curing malaria in nonimmune subjects. The treatment scheme for such persons should include an additional treatment on day 7 for nonimmune individuals. This drug was well tolerated in our patients, indicating that halofantrine will be useful in the treatment of multidrug-resistant malaria in nonimmune persons.

Neuropsychiatric side effects after the use of mefloquine.

This study describes neuropsychiatric side effects in patients after treatment with mefloquine. Reactions consisted mainly of seizures, acute psychoses, anxiety neurosis, and major disturbances of sleep-wake rhythm. Side effects occurred after both therapeutic and prophylactic intake and were graded from moderate to severe. In a risk analysis of neuropsychiatric side effects in Germany, it is estimated that one of 8,000 mefloquine users suffers from such reactions. The incidence calculation revealed that one of 215 therapeutic users had reactions, compared with one of 13,000 in the prophylaxis group, making the risk of neuropsychiatric reactions after mefloquine treatment 60 times higher than after prophylaxis. Therefore, certain limitations for malaria prophylaxis and treatment with mefloquine are recommended.

Serologic evidence of human immunodeficiency virus infection of the central nervous system in African patients with acquired immunodeficiency syndrome.

The intrathecal synthesis of antibodies to human immunodeficiency virus (HIV) was determined by 3 different immunoassays in 15 African patients with pre-acquired immunodeficiency syndrome (AIDS) and AIDS. Isoelectric focusing together with affinity-mediated immunoblot were found to be superior to enzyme-linked immunosorbent assay and Western blot in providing information not only about the antigen specificity of locally produced antibodies but also about their clonal distribution. In 9 of the subjects, HIV-specific oligoclonal bands were demonstrable with higher frequency or intensity in the cerebrospinal fluid than in the autologous serum, indicating autochthonous synthesis of HIV-related antibodies.

[Prophylactic treatment of pancreatitis with antibiotics? (author's transl)].

In acute pancreatitis the standard treatment is with antibiotics given prophylactically. Available studies indicate that the usefulness of such chemotherapy in the milder form of the disease (degree of severity I) has not yet been fully established. In the absence of contradictory results, prophylactic antibiotic treatment can, however, be recommended in severe pancreatitis (degrees II and III) and in those conditions induced by ethyl or of idiopathic origin. In all forms showing underlying biliary tract disease and in pancreatitis complicated by infection, antibiotic treatment should invariably be administered. Administration of broad-spectrum antibiotics which can be excreted via the bile duct, e.g. ampicillin or tetracycline, is preferable.

[The significance of the evocative test in the diagnosis of chronic pancreatitis (author's transl)].

To evaluate the predictive value of the evocative test (E.T.) in the diagnosis of pancreatitis, the E.T. was performed in 35 healthy subjects (group I), 65 patients with a presumptive clinical of chronic pancreatitis (group II), and 52 patients with proved chronic pancreatitis (group III). In group I, false positive results were obtained in 11,4% of the patients, the increase in lipase above the upper limit of normal was relatively small. The patients of group II gave abnormal E.T.'s in 63%, reduced faecal chymotrypsin activities being found in 40%, and steatorrhea in 28% of the cases. Positive E.T.'s were associated with abnormal chymotrypsin and faecal fat determinations in 51% and 27%, respectively. In group III,, a positive E.T. was obtained in 60%, the test results show a signifikant negative correlation with the extent of pancreatic exocrine insufficiency. In group of patients with confirmed chronic pancreatitis but without steatorhea, the E.T. was positive in 72%. The E.T. has a limited value in the diagnosis of early stages of chronic pancreatitis.

[Adenoid-cystic carcinoma of the larynx (author's transl)].

Report on 5 cases of adenoidcystic carcinoma of the larynx and review of the literature, containing about 60 further reports. About 80% of these tumors arise in the subglottice laryngo-tracheal transition region, 20% in the ventricular cord and the epiglottis. The vocal cords containing no mucus glands are never the origin of adenoid cystic carcinomas. These tumors grow under an intact mucosa and reach very often an enormous extension until dyspnoea, dysphagia and recurrent never paresis lead to diagnosis. The clinical course of these tumors ist not preditable--even not by their histological structure. In some cases the outcome is rapidely fatal by local growth and metastases, in others a many year long survival can be reached, but there exists no reliable report on a "cured" adenoid cystic carcinoma of the larynx. By radical surgery only better results can be expected. Irradiation produces long lasting remissions in some cases.

Functional and morphological alterations of the exocrine pancreas in the rat following pretreatment with rifampicin.

Following oral pretreatment with rifampicin over 3 and 9 days, the exocrine pancreatic function was studied in urethane-anaesthetized rats under exocrine stimulation. The volume and electrolyte content, and especially the protein and amylase outputs of the pancreatic secretion showed a virtually dose- and time-dependent decrease. Histologically, there was a corresponding decline of the zymogen granules in the acinar cells. The suggested explanation for the observed disorders of the pancreatic exocrine function is primarily an inhibition of protein synthesis due to rifampicin.

[The longterm results of osteoplastic frontal sinus surgery for recurrent disease (author's transl)].

The osteoplastic frontal sinus operation permits the complete removal of sinus mucosa and, with blockage of the frontonasal duct, the reliable obliteration of the sinus cavity. Two patients, who had had several surgical procedures for recurrent frontal sinusitis, became symptom free after this procedure. After an interval of 5 to 6 years the cosmetic result remained satisfactory and ossified obliteration of the sinus was demonstrable radiologically.

[Exocrine pancreatic function in rats after treatment with cyclophosphamide (author's transl)].

After a 3- and 8 day administration of cyclophosphamide to rats an approximately dose-dependent decrease in the pancreatic secretion of protein and enzyme activities was demonstrable in vivo under exogenous stimulation with secretin and pancreozymin. The volume of secretion and the electrolyte outputs were found to be slightly lowered. An impairment in enzyme synthesis resulting from cyclophosphamide administration is suggested as the major cause of the observed changes in secretion.

[Behavior of exocrine pancreatic function during treatment with antibiotics and antineoplastic agents].

The thesis is composed of two parts, the first part is concerned with experiments in rats, the second part confirms the findings in human beings. After administration of oxytetracycline, chloramphenicol and cyclophosphamide, respectively, to rats an approximately dose-dependent decrease in the pancreatic secretion of proteins and enzyme activities was demonstrable in vivo under exogenous stimulation. The exocrine pancreatic function was studied in humans by performing a secretin-pancreocymin test before and after treatment with oxytetracycline or chloramphenicol and before and after massive-dose therapy with cyclophosphamide or combined cytotoxic treatment (as outlined by De Vita). The investigations further included an examination of the exocrine pancreatic function in subjects on maintenance therapy with cyclophosphamide or busulfan and a comparison with the exocrine pancreatic function in a group of controls. In the oxytetracycline-treated humans there was a depression of the amylase and lipase activities in the duodenal secretion. Administration of chloramphenicol produced a decrease in the amylase output only. In the patients on massive-dose or continued therapy with cyclophosphamide the pancreatic function remained essentially unchanged. In contrast, cytotoxic combination treatment resulted in decreased activities of amylase and lipase. After maintenance treatment with busulfan a reduction of the trypsin and amylase activities was detectable. The volume and electrolyte outputs were found to remain essentially unchanged in all investigations. An impairment in enzyme synthesis is suggested as the major cause of the observed changes of pancreatic secretion after antibiotic and cytotoxic treatment.
