Severe hepatotoxicity with jaundice associated with paroxetine.

Hepatotoxicity due to paroxetine, a selective serotonin reuptake inhibitor, is very rare, and to the best of our knowledge, only five cases of liver injury in association with paroxetine have previously been reported in the medical literature. We describe the clinical, biochemical, and pathological findings in a patient with paroxetine hepatotoxicity, which was reversed after withdrawal of the drug. The present case and the others previously reported suggest that hepatotoxicity should be taken into account as a rare complication, sometimes severe, that may occur with paroxetine.

Squamous cell carcinoma of the lung presenting with cutaneous leukocytoclastic vasculitis: a case report.

An elderly patient with paraneoplastic cutaneous leukocytoclastic vasculitis (CLV) leading to the discovery of an as-yet asymptomatic, potentially surgically curable squamous cell carcinoma of the lung is presented. This type of vasculitis has not been previously described in association with this type of lung cancer. Since vasculitic paraneoplastic syndromes, including CLV, may develop before the clinical presentation of malignant tumors, the present case and others previously reported strongly suggest that in apparently idiopathic CLV, patients should be evaluated for the presence of occult malignancy that could be curable by early detection.

Coma and seizures due to severe hyponatremia and water intoxication in an adult with intranasal desmopressin therapy for nocturnal enuresis.

Desmopressin, a synthetic analogue of the antidiuretic hormone, is an effective medication for primary nocturnal enuresis for both children and adults. Its safety is well established. Although it has a favorable side effect profile, because of its pharmacological effect, intranasal desmopressin can rarely induce water intoxication with profound hyponatremia if given without adequate restriction of water intake. The authors describe an adult patient with water intoxication and severe hyponatremia accompanied by loss of consciousness and seizures after 2-day intranasal administration of desmopressin. The present and the previously reported cases emphasize the need for greater awareness of the development of this serious and potentiallyfatal complication. In addition, to adjust the drug to the lowest required dosage, adequate restriction of water intake is recommended, and serum levels of sodium should be measured periodically to allow for early detection of water intoxication and hyponatremia.

[Physicians' assessment of computerized prescribing].

Prescription errors are a major source of preventable adverse drug events. Computerized prescribing (CP) which screens physicians' order for mistakes, drug-allergy, drug-disease, drug-laboratory and drug-drug interactions can prevent many of these errors and improve quality of care. However, computerized systems are often time-consuming, difficult to handle, and may create their own mistakes. Following the introduction of CP on an internal medicine ward, we administered a questionnaire to evaluate physicians' opinions about the new system. The survey assessed computer literacy, ease of using CP, effects on time management, opinion of users regarding error prevention, and usefulness of the information provided. Opinions were generally favorable; most users felt that CP makes their work more accurate, reduces errors, is easy to learn and to use, and provides important and useful information. Physicians were most critical of equipment failure and drugs and dosages not included in the CP program, a result of rapid development of the system. Errors resulting from the use of CP were considered minimal. Comparison of physicians, with and without previous experience with computer work, as well as local and foreign graduates, revealed minor differences. But once physicians learn to work with a well-organized CP system and computerized work stations, they appreciate the order, safety and knowledge they provide.

Role of tumor necrosis factor-alpha in the differential diagnosis of parapneumonic effusion.

OBJECTIVE: This study was undertaken to investigate the role of tumor necrosis factor-a (TNF-a) in discriminating between uncomplicated parapneumonic effusion (UCPPE) and complicated parapneumonic effusion (CPPE). METHOD: Using a commercially available high sensitivity enzyme-linked immunosorbent assay (ELISA) kit, concentrations of TNF were measured in the serum (TNFs) and pleural fluid (TNFpf) of 21 patients with parapneumonic effusion (PPE), 13 patients with UCPPE, and 8 patients with nonempyemic CPPE. RESULTS: No significant difference in values of TNF concentration was found between the group with UCPPE and that with CPPE (P > 0.05). Concentration levels of TNFpf were significantly higher in the group with CPPE than in that with UCPPE (P = 0.0008). Levels of TNF in pleural fluid were significantly higher than in serum in both groups (P < 0.001). The ratio of TNF in pleural fluid to that in serum (TNFr) was significantly higher in the CPPE group than in the UCPPE group (P = 0.0002). At an optimal cutoff point of 10.7 pg/mL for TNFpf, the sensitivity was 87.5%, specificity was 92.3%, positive predictive value was 87.5%, negative predictive value was 93.3%, and total accuracy was 90.5% (P < 0.001). At an optimal cutoff point of 3.0 for TNFr, all values were 100% (P < 0.00001). CONCLUSIONS: The results of this study indicate that TNFpf, and particularly TNFr, may be helpful in discriminating between UCPPE and CPPE. However, further studies are needed in a larger population to confirm these findings.

Tumour necrosis factor alpha in the diagnostic assessment of pleural effusion.

We investigated the role of tumour necrosis factor-alpha (TNF) in the evaluation of pleural effusion aetiology. Using a commercially-available ELISA kit, concentrations of TNF were measured in the serum and pleural fluid of patients with malignant effusions (n=19), uncomplicated parapneumonic effusions (n=13), and exudative (n=13) and transudative (n=13) effusions due to congestive heart failure (CHFex and CHFtr, respectively). Serum TNF did not differ significantly between the four groups (p>0.05). In the group with malignancy, pleural fluid TNF was significantly higher than in the other groups (p<0.001), which were not significant different from each other (p>0.05). However, a considerable overlap between all four groups was found. Pleural fluid TNF was significantly higher than serum TNF in the malignant and the uncomplicated parapneumonic groups (p<0.001), and there was a significant positive correlation between serum TNF and pleural fluid TNF in the group with uncomplicated parapneumonic effusion (r=0.7, p<0.005), in the group with CHFex (r=0.54, p<0.01), and in the group with CHFtr (r=0. 8, p<0.005), but not in the group with malignancy. Pleural fluid TNF:serum TNF (TNF ratio) was significantly higher in the malignancy group than in the other groups (p<0.001); no significant difference was found between the other three groups (p>0.05). At an optimal cut-off point of 2.0 for TNF ratio, determined by ROC analysis for discrimination between malignant and non-malignant groups, sensitivity was 84%, specificity 90%, and total accuracy 88% (p<0. 0001). TNF ratio might be helpful in the diagnostic assessment of exudative pleural effusion.

Propafenone-induced ataxia: report of three cases.

Propafenone is an effective antiarrhythmic drug used widely for the treatment of supraventricular and ventricular arrhythmias. Although it is generally well tolerated, 30 to 45% of patients may experience adverse cardiac effects. In 15 to 20% of patients, adverse effects may involve other organ systems. A wide variety of adverse central nervous system effects have been reported in association with propafenone; dizziness is the most common. Ataxia caused by propafenone has been reported to the pharmaceutical companies and drug monitoring agencies, but has not been well described or emphasized in the medical literature. We describe 3 elderly patients with moderate to severe ataxia that occurred while they were taking propafenone.

Deep venous thrombosis associated with acute brucellosis--a case report.

Vascular complications, including arteries and veins associated with Brucella infection, have rarely been reported. To date, only three cases of deep venous thrombosis (DVT) of the lower extremities associated with brucellosis have been previously reported. The authors describe another case of DVT of the right leg in association with acute Brucella infection. Since infection with Brucella may be asymptomatic, and the manifestations of acute brucellosis are exceedingly nonspecific, and in view of the potential for Brucella to cause unexplained or unusual illness involving almost any organ including blood vessels, the authors' case and those previously reported suggest that brucellosis should be included among the causes and infections taken into account in patients suffering from DVT, particularly in those coming from Brucella-endemic areas.

Maternal obesity and pregnancy outcome.

BACKGROUND: Obesity, a common condition in developed countries, is recognized as a threat to health. OBJECTIVES: To describe the distribution of weight in pregnant women and evaluate the influence of obesity on pregnancy outcome in a high parity northern Israeli population. METHODS: The study included 887 women who gave birth in the Western Galilee Medical Center during the period August to November 1995. The patients were classified as underweight, normal weight, overweight, or obese according to body mass index. Maternal demographic, obstetric, and perinatal variables were compared. A control group of 167 normal weight women were matched with the obese group for maternal age, parity, and gestational age. RESULTS: Obese mothers had a higher incidence of gestational diabetes and pregnancy-induced hypertension compared to normal weight mothers (5.4% vs. 1.8%, and 7.2% vs. 0.6% respectively, P < 0.01), a higher rate of labor induction (20.4% vs. 10.2%, P < 0.01), and a higher cesarean section rate (19.6% vs. 10.8%, P < 0.05). There was also a significant difference in the prevalence of macrosomia in the offspring (16.8% vs. 8.4%, P < 0.05). CONCLUSION: Obese pregnant women are at high risk for complications during delivery and therefore need careful pre-conception and prenatal counseling, as well as perinatal management.

Hyponatremia during therapy with amiodarone.

We describe an elderly woman who presented with significant hyponatremia caused by the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) during therapy with amiodarone. The hyponatremia resolved after discontinuation of the drug and did not recur during a follow-up period of 6 months. Such an association has previously been reported only once in the medical literature. Since severe hyponatremia can produce significant neurologic damage and is associated with a high mortality rate, clinicians should be aware that this complication may occur during amiodarone therapy.

Creatine kinase as a biochemical marker in diagnosis of placenta increta and percreta.

We describe 1 case of placenta increta and 1 of placenta percreta, both associated with elevated maternal serum creatine kinase concentration. In patients with placenta previa and ultrasonographic findings of an abnormally adherent placenta, an unexplained elevation in maternal serum creatine kinase level should alert the clinician to the possibility of placenta increta or placenta percreta, with an attendant increase in maternal morbidity.

T-cell chronic lymphocytic leukaemia with pulmonary involvement and relapsing BOOP.

We report on a case of T-cell chronic lymphocytic leukaemia involving the lung, with clinical, radiological and histological evidence of relapsing bronchiolitis obliterans-organizing pneumonia in a 70-yr-old female. Pulmonary disease was the major clinical manifestation of this chronic lymphocytic leukaemia. The first two episodes of the patient's pulmonary disorder resolved without treatment, and the third episode was treated with cytotoxic agents as part of the leukaemia treatment regimen. Two additional episodes of the pulmonary disorder occurred; both responded to prednisone.

Severe life-threatening hyponatremia during paroxetine therapy.

Hyponatremia secondary to the syndrome of inappropriate secretion of antiduretic hormone (SIADH) is an uncommon complication of treatment with the antidepressants the selective serotonin reuptake inhibitors (SSRIs). These effective anti-depressant agents are becoming widely used because of their favorable side effect profile and their safety in overdose. Although most reports have implicated fluoxetine in causing hyponatremia, there have also been a few reports of hyponatremia associated with paroxetine. We describe an elderly patient with severe life-threatening hyponatremia in association with paroxetine therapy. The present case and the others previously reported emphasize the need for greater awareness of the development of this serious and potentially fatal complication, and suggest that serum sodium concentration should be measured periodically in elderly patients soon after they start taking any agent of the SSRIs, especially during the first 2 to 4 weeks of treatment.

[Verapamil-associated liver injury].

Hepatotoxicity due to verapamil is very rare and to the best of our knowledge only 10 cases have been reported. A 54-year-old woman developed cholestatic liver injury and pruritus following treatment with sustained-release verapamil (240 mg/day) for arterial hypertension. The pruritus and all hepatic biochemical abnormalities completely resolved after withdrawal of the drug. Similar to previously reported cases, the pathogenic mechanism of verapamil-associated liver injury in our patient was, most probably, idiosyncratic. These cases emphasize the need for awareness of the possibility that verapamil may occasionally induce liver injury, sometimes severe and potentially fatal.

Central nervous system reactions associated with famotidine: report of five cases.

H2-receptor antagonists may cause various types of central nervous system reactions, particularly in patients with advanced age and/or impaired renal or liver function. These reactions have rarely been reported in association with famotidine. In five elderly patients, four of them with renal failure, central nervous system reactions developed shortly after initiation with famotidine therapy. These adverse reactions completely resolved after famotidine withdrawal. The authors' five cases and the other seven previously reported emphasize the need for dosage adjustment of famotidine in elderly patients and in those with renal failure, and that these patients should be carefully monitored for development of central nervous system reactions, which sometimes could be very serious.
