A case of lactic acidosis associated with phenformin therapy for diabetes mellitus is reported, and 34 previously reported cases of lactic acidosis associated with phenformin therapy are reviewed to determine if any predisposing factors to lactic acidosis were apparent. Observations of sex, age, duration of diabetes, pathologic conditions, dosage, duration of phenformin therapy and the onset of symptoms preceding lactic acidosis were made. Renal impairment, urinary tract infections, hepatic impairment, ethanol ingestion and poorly controlled congestive heart failure were found to be predisposing factors to lactic acidosis. The appearance of a syndrome of impending lactic acidosis consisted of anorexia, nausea, vomiting with abdominal pain or lethargy.

The response rate and survival obtained with the combined regimen of bleomycin, ifosfamide, and cis-platinum (BIP) were analyzed in a series of 24 patients with recurrent cervical carcinoma in previously irradiated area. The doses were 30 mg, 5000 mg/m2, and 50 mg/m2, respectively. Mesna was given simultaneously (6000 mg/m2). None of the patients were treated with prior chemotherapy. All the patients were evaluable for toxicity and 20 for response. The median survival in patients evaluable for response was 9 months. No complete and 3 partial responses (15%) were observed, with a median duration of survival of 10+ months (range, 9(+) -16). Stable disease was observed in 8 patients (40%) with a median duration of survival of 9.5 months (range, 6(+) -20). Progressive disease was observed in 9 patients (45%) with a median duration of survival of 6 months (range, 3-25+). Four patients received one course only because of toxicity. One of these patients died at home 6 days after the first course, probably because of dehydration. The main toxicities were myelosuppression, renal impairment, alopecia, and nausea/vomiting. In conclusion, the BIP regimen has considerable toxicity. We were not able to confirm the high response rates earlier reported in pelvic recurrence inside a previously irradiated area. Emphasis in future studies must continue to be placed on the development of more active single agents and combinations.

Cilazapril is a new once-daily angiotensin-converting (ACE) enzyme inhibitor which has been administered to 4,500 patients with mainly mild to moderate essential hypertension in a multinational clinical research program. Sitting diastolic blood pressure was reduced by about 9 mm Hg from baseline (p less than 0.01) after 4 weeks of treatment with cilazapril 1.25-10 mg/day in double-blind placebo-controlled studies. Total responder rates to cilazapril were usually 50-60% compared with 30% to placebo. Adding hydrochlorothiazide 12.5 mg/day to cilazapril 5.0 mg/day increased the total responder rate from 52 to 71%. Double-blind dose titration studies for 8 weeks showed that cilazapril 2.5-5 mg/day possessed equivalent efficacy to usual therapeutic regimens of sustained release propranolol, captopril, hydrochlorothiazide, atenolol and enalapril, Cilazapril did not affect heart rate. During long-term open administration for 52 weeks, or longer, cilazapril, either alone or in combination with hydrochlorothiazide, effectively maintained control of blood pressure. Treatment of patients with severe hypertension with cilazapril plus hydrochlorothiazide achieved a total responder rate of 73%. Adverse events were mostly observed within the first 8-16 weeks of treatment, with headache, dizziness, fatigue, nausea, cough and chest pain being the most frequent. Non-life-threatening angioedema, facial edema and mild hypotension occurred in less than or equal to 0.2% of patients, and orthostatic hypotension was reported in 2%. Abnormal laboratory test values were rarely found with cilazapril treatment. Of the 2.3% of patients with elevated serum creatinine, at any time point during the study and irrespective of outcome on continuation with cilazapril therapy, about two thirds had prior renal impairment.(ABSTRACT TRUNCATED AT 250 WORDS)

Aspirin (acetylsalicylic acid) and its salicylate derivatives are effective antipyretic, analgesic, and anti-inflammatory agents that are still very widely used by the elderly despite the advent of newer, potentially safer nonsteroidal anti-inflammatory drugs (NSAIDs). However, none of the new NSAIDs have been proven to be more effective than aspirin or salicylic acid. Chronic salicylate intoxication which is most common in the elderly, may occur with therapeutic doses. Increased toxicity in older patients often appears due to inadvertent overdosage. Dual prescribing or additional use of nonprescription salicylates are some causes of unwitting long term toxicity. According to some studies, systemic clearance of salicylate (mainly by hepatic metabolism) is reduced with age, as is renal elimination. These changes are of increased importance in the elderly using high therapeutic doses of salicylates when metabolism is saturated and more unchanged drug is available for renal excretion. In the face of renal impairment, the risk of toxicity is increased. The diagnosis of acute salicylate intoxication generally does not pose diagnostic problems. Patients often present with a history of intentional overdose, with hyperventilation, fever, and nausea. The diagnosis can be confirmed by measuring serum salicylate concentrations. Chronic intoxication often poses a diagnostic dilemma with atypical presentations mimicking other disease states such as diabetic ketoacidosis, delirium, cerebrovascular accident, myocardial infarction or cardiac failure. The diagnosis of salicylate intoxication should be borne in mind when an older patient presents with recent deterioration in activities of daily living with no known cause. Plasma salicylate concentrations should be measured if salicylate intoxication is suspected, even if there is no documented history of salicylate ingestion. The risk of salicylate nephrotoxicity is also increased with age, and upper gastrointestinal haemorrhage is associated with increased mortality in older age groups. Treatment of acute toxicity consists of prompt recognition of salicylate intoxication, use of activated charcoal, correction of acid-base abnormalities, general supportive measures, and if concentrations are extremely high, dialysis can be effectively used. Chronic toxicity, which can occur even with marginally high salicylate concentrations, is treated with drug withdrawal and supportive therapy. Chronic salicylate toxicity can be averted by prescription of conservative doses of drug, avoidance of concomitant use of different salicylate preparations, and therapeutic monitoring to guide dosage. Renal function should be monitored to detect nephrotoxicity from chronic salicylate therapy. Patients should be regularly screened for evidence of gastrointestinal bleeding.(ABSTRACT TRUNCATED AT 400 WORDS)

In a prospective open study, seven patients with persistent pustulosis palmaris et plantaris were treated with oral Cyclosporin A (CsA). Clinical efficacy was assessed on a semi-quantitative 0-4 point scale for erythema, desquamation, induration and pustulation. CsA controlled skin lesions in doses ranging from 1.1 to 6.1 mg/kg body weight/day. Clinical side effects included renal impairment, nausea and tiredness. Rapid recurrence of the skin lesions was observed on withdrawal or insufficient treatment with the drug.

The pharmacokinetics of an i.v. bolus of pimobendan (P) 2.5 mg and 5.0 mg, its tolerability and the effect on heart rate and blood pressure have been studied in 12 subjects (42-70 y) suffering from severe terminal renal impairment. Plasma level data were compared with those obtained in a previous investigation in healthy volunteers. Pharmacokinetics were dose linear and were comparable to those in healthy subjects. No adjustment of the dose of P is necessary in patients with severe renal impairment. Tolerability of P, observed by means of blood pressure monitoring, clinical chemistry tests, electrocardiography and subjective judgement resulted in 4 complaints out of 12 patients: three suffered from orthostatic problems and vomiting, and one patient had nausea. Mean heart rate was elevated by 19% (2.5 mg) and 16% (5.0 mg). Blood pressure was significantly reduced after 2.5 mg P (23% systolic and 26% diastolic pressure), and after 5.0 mg P by 25% systolic and 23% diastolic pressure.

The role of chemotherapy in the management of patients with cancer of the paranasal sinus has not been defined. An analysis of 24 evaluable patients treated with chemotherapy as part of their overall therapy was performed. There were 16 male patients and eight female patients. Sixteen patients were previously untreated and eight had recurrent disease after surgery and/or radiotherapy. Six of the previously untreated patients had metastatic disease on presentation (four central nervous system (CNS) and two lung), and four recurrent patients had CNS involvement. The majority of patients (78%) had squamous cell carcinoma. The chemotherapy regimens included cisplatin (CDDP), vincristine (VCR), and bleomycin (COB), 5-fluorouracil (5-FU) infusion and CDDP, or 5-FU/CDDP and methotrexate (MTX). All patients had computed tomography (CT) measurable disease. Previously untreated patients underwent surgery and/or radiotherapy postchemotherapy. The overall response rate to chemotherapy for previously untreated patients was 82% (complete response [CR] 44%, partial response [PR] 38%) and for recurrent patients 88% (CR 38%, PR 50%). Predominant toxicities were nausea, vomiting, myelosuppression, mucositis, and renal impairment. The median survival of the previously untreated patients, based on response to chemotherapy, was as follows: CR 21+ months (range, 10+ to 81 months), PR 13.5 months (range, 2 to 21 months), and no response (NR) 3 months (range, 1 to 7 months). The median survival of patients with recurrent disease was as follows: CR 16 months, PR 13.5 months, and NR 5 months. We conclude that patients with paranasal cancers are responsive to CDDP-containing combinations. The role of adjuvant chemotherapy in previously untreated, locally advanced patients needs to be demonstrated by future randomized trials.

Fluoxetine is an antidepressant drug with a unique chemical configuration which enhances serotoninergic transmission by inhibiting serotonin uptake. The chronic presence of serotonin in the synaptic cleft reduces postsynaptic receptors, a postulated explanation for its antidepressant efficacy. Comparative studies show that the therapeutic effectiveness of fluoxetine is equal to that of imipramine, amitriptyline, and doxepin. A 20 mg morning dose alleviates most depressions. The long half-life of one to three days for the parent compound and seven to 15 days for the active metabolite, desmethylfluoxetine, is largely unaffected by age or renal impairment. Nausea, nervousness, insomnia, and headache are the most common side effects. Therapeutic doses do not affect cardiac conduction or cause orthostasis. A primary benefit of this drug is its significant relative safety in overdoses as compared to other antidepressants.

A study was conducted to determine if cisplatin (CDDP) can be given at higher doses than usual, utilizing aggressive supportive measures. Twelve patients were entered into three dose levels of CDDP: level I, 180 mg/m2 given as a short infusion; level II, 220 mg/m2 also given as a short infusion; level III, 200 mg/m2 divided in five daily doses, each infused over 6 hours. In all cases, CDDP was dissolved and given in 250 ml of a 5% saline solution. For levels I and II, intravenous hydration with 200 to 250 ml/hour D5 1/2NS with potassium and magnesium supplements, was started 24 hours before therapy and continued for 3 to 4 days after, longer if nausea persisted. Mannitol was given before (25% solution, 50 ml bolus) and after (20% solution, 500 ml over 3 hours) CDDP. At level III hydration with the same intravenous (IV) fluids was begun the day before therapy and continued without interruption at 200 to 250 ml/hour for a minimum of 24 hours after the completion of the 5 days of chemotherapy. Each daily dose of CDDP was preceded by injection of mannitol (25% solution, 50 ml bolus) and accompanied by a 6-hour infusion of 1000 ml 20% mannitol. Three patients received five CDDP courses at level I; 4 patients, seven courses at level II; and 5 patients, seven courses at level III. Ototoxicity was dose-limiting in three patients at level II. Transient elevation of serum creatinine was seen following two courses at level I and two courses at level II. The renal impairment was asymptomatic in all cases; dialysis was not needed. At level II, leukocyte nadir counts between 1.0 and 2.0 X 10(3)/mm3 were seen following two courses and between 2.0 and 3.0 X 10(3)/mm3 following three courses. Platelet nadir counts below 50 X 10(3)/mm3 were recorded after four courses and between 50 and 100 X 10(3)/mm3 after one course. Nausea and vomiting occurred frequently, but were tolerable. At level III, myelosuppression was dose-limiting. Nadir leukocyte counts between 1.0 and 2.0 X 10(3)/mm3 followed four courses and between 2.0 and 3.0 followed one course. Nadir platelet counts below 50 X 10(3)/mm3 were seen after three courses; two patients required prophylactic platelet transfusions. Nadirs between 50 and 100 X 10(3) platelets/mm3 followed three further courses. Ototoxicity and nephrotoxicity did not occur at level III.(ABSTRACT TRUNCATED AT 400 WORDS)

Twenty-seven patients with measurable or evaluable, regionally advanced or metastatic head and neck cancer were given a combination of cyclophosphamide (C), Adriamycin (A), and cis-diamminedichloroplatinum (II) (P). Most patients had received extensive prior surgery and/or radiation therapy. Among 25 evaluable patients, the overall response rate was 64% (16/25) with 3/25 complete responders and 13/25 partial responders. The median survival for the entire group of 25 patients and the median response duration for the subset of 16 patients experiencing tumor regression were 8.1 and 7.0 months, respectively. Responders lived significantly longer than nonresponders (11 months vs. six months, P less than 0.01). According to covariate analysis, the difference seems to reflect the influence of response to treatment and not other confounding variables. Almost all patients experienced anorexia, nausea, vomiting, and a pervasive feeling of ill-health. In fact, six patients declined further treatment and five of these had objective tumor regressions. Recurrent disease was detected three months following discontinuation of chemotherapy in four of these five patients and seven months later in the fifth. Myelosuppression was clinically acceptable and there was in this dosage and schedule no evidence of hepatic or renal impairment. Although the CAP regimen has substantial antitumor activity, the program is clinically rigorous and should remain an investigational treatment modality at the present time.
