The safety of etodolac, a new nonsteroidal anti-inflammatory drug (NSAID), was reviewed by examining data from 3,302 patients enrolled in double-blind and open-label clinical trials and from 8,334 patients taking etodolac in post-marketing surveillance studies. The review determined that gastrointestinal disturbances are the most frequently reported side effects, followed by headache, dizziness, rash, and pruritus. The rate of abdominal pain and dyspepsia is similar to that observed with several other NSAIDs but is lower than that seen with aspirin. Gastrointestinal ulceration occurs in less than 0.3% of patients taking etodolac, and drug-related hepatic, renal, and hematologic dysfunctions are rare. The elderly appear to be no more at risk of experiencing adverse effects than the general population. Overall, the review confirmed the excellent safety profile of etodolac reported previously.

On the basis of epidemiologic and experimental evidence of an anticancer activity of vitamin A, a randomized clinical trial was activated in Milan with the aim of evaluating if retinol palmitate administration (per os, 300,000 I.U. daily) after complete resection of stage Ia non small-cell lung cancer could reduce the occurrence of cancer relapses (within 3 years) and/or the occurrence of new primary tumors (beyond 3 years). By September 1987, 181 patients had entered the trial: 87 in the treatment arm and 94 in the control arm. After a median follow-up of 14 months, the interim analysis was focused on the evaluation of toxicity, compliance, and early recurrences. Although the large majority of patients were affected by skin and mucous membrane desquamation and dryness during treatment, these symptoms were generally mild and well tolerated, and never induced the patient to stop the treatment. Other side effects like headache, hair loss, itching, or dyspepsia were detected at a much lower frequency. Only in 3 patients the treatment was interrupted, because of signs or symptoms potentially related to vitamin A administration. At the time of the analysis, a total of 42 (23%) patients had relapsed; 16 (18%) in the treated arm, and 26 (28%) in the control arm. The largest difference between treated patients and controls was observed for bone metastases (2 vs. 7) and brain metastases (3 vs. 6), and for squamous histology (6 vs. 11). Only 2 cases of new primary cancer were detected, both in the control arm. These results are promising both in terms of tolerance and efficacy of treatment, but given the short median follow-up they must be very cautiously interpreted. A longer follow-up is necessary to establish whether a significant proportion of early recurrences could be prevented, or only delayed, by vitamin A administration.

Fifty-two of 142 (37%) American ex-prisoners of war that worked on the Burma-Thailand Railroad during World War II were found to have previously unrecognized symptomatic Strongyloides stercoralis infections. A characteristic urticarial creeping skin eruption on the abdomen, buttocks and thighs occurred in 92%. Infection was also associated with pruritus ani, abdominal pain, indigestion, heartburn, and diarrhea. Demonstration of larvae in ether-formalin stool concentrates in these chronic low density infections required 5 hours of microscopy per case to detect 90% of positive cases. Therapy with thiabendazole resulted in a clinical cure in 93% and a microscopic cure in 100%; but was associated with frequent side effects. Chronic strongyloidiasis should be considered in veterans of Far East conflicts and in others with intimate soil contact in rural Strongyloides stercoralis-endemic areas who present with recurrent creeping skin eruption, abdominal pain, and eosinophilia.

One hundred and sixty ex-servicemen who had been prisoners of war in south-east Asia during 1942-5 were investigated for infection with Strongyloides stercoralis. Larvae were found in 44 (27.5%) of the men, who had therefore been infected for 34-37 years. Direct microscopy of the faeces was the most successful diagnostic method, giving a positive result in 37 cases (84%); multiple examinations were often necessary. Faecal culture was positive in 30 cases (68%), but examination of duodenal fluid obtained with the string test gave a positive result in only 17 (39%). The mean blood eosinophil count and mean serum IgE concentration were higher in the infected men, though normal values were often found in individual cases. Clinical manifestations of isolated strongyloides infection were analysed by comparing the infected men with control groups of ex-prisoners in south-east Asia without proved strongyloidiasis and ex-prisoners in Europe. Twenty-nine infected men (66%) complained of non-specific urticaria, and 13 (30%) had pathognomonic larva currens. Gastrointestinal symptoms significantly more common in the infected group were diarrhoea, indigestion, lower abdominal pain, pruritus ani, and weight loss (p <0.05-p <0.0005).The study group was thought to be reasonably representative of Allied ex-servicemen imprisoned in south-east Asia during the second world war. Probably there are many thousands of infected persons in several countries. The worm has an unusual ability to multiply, and larvae may spread throughout the body in immunosuppressed subjects.

Limb activity meters, otherwise modified self-winding watches that can record limb agitative movements such as in itch-provoked scratch, were introduced for an objective evaluation of the relative effectiveness of three antipruritic drugs: chlorpheniramine, cyproheptadine, and sulphapyridine for palliating pruritus associated with chloroquine chemosuppressive treatment of acute malarial febrile paroxysms in eighteen adult patients. Six fit and healthy subjects were also studied to obtain data for unmedicated controls. The meters were used to monitor the upper and lower limb activities of the patients during nocturnal sleep for 6 hours over 3 consecutive nights, after they had developed the chloroquine-induced pruritus and were then administered the antipruritic medications, six patients per drug, by a random selection. Sulphapyridine antipruritic treatment significantly reduced the activities of the upper limbs of itchy patients much greater than did cyproheptadine (P < 0.0001, right hand; P < 0.01 left hand). However sulphapyridine-treated patients still itched significantly more than controls from the greater activities in the dominant right hand of the patients (P < 0.05). Cyproheptadine had a marginally-better performance than chlorpheniramine, generally, in palliating the chloroquine-induced pruritus but only in one of 3 nights, for the right hand recordings, were the limb activities significantly different. There was no significant difference observed in the activities of the lower limbs for the unmedicated controls compared to itchy patients, irrespective of the antipruritic treatment mode. Five out of the 6 patients treated with sulphapyridine also complained of anorexia plus a feeling of fullness or indigestion.(ABSTRACT TRUNCATED AT 250 WORDS)

Palliative treatment is appropriate for most patients with cancer of the head of pancreas. Insertion of a biliary stent relieves jaundice and pruritus but it is not known if stenting affects other symptoms or changes the quality of life. Nineteen patients have completed a standard questionnaire to assess symptom relief and quality of life after stent insertion. After stenting there was complete relief of jaundice and pruritus. Furthermore, there was also considerable improvement in anorexia and indigestion. All patients had anorexia before stent insertion, this was moderate/severe in 13 (68.4%). Anorexia was significantly better (p < 0.01) a week after stenting and this benefit was maintained at 12 weeks (p < 0.01). Sixteen (84.2%) patients complained of indigestion before stenting, moderate/severe in 11 (57.9%). This was significantly better (p < 0.01) a week after stenting with complete relief in six at eight weeks (p < 0.01). Fifteen (78.9%) felt that their mood was good/very good before stent insertion and this was unchanged even at the 12 week assessment. A similar result was obtained for physical health and level of activity. In conclusion stent insertion not only relieves jaundice and pruritus in these patients but also improves other symptoms and quality of life. The considerable improvement in appetite after stenting was of particular benefit.

In a prospective study, the prevalence of 15 physical symptoms and symptom groups was evaluated in 1635 cancer patients referred to a pain clinic. In addition to pain, patients suffered an average of 3.3 symptoms: insomnia (59%), anorexia (48%), constipation (33%), sweating (28%), nausea (27%), dyspnea (24%), dysphagia (20%), neuropsychiatric symptoms (20%), vomiting (20%), urinary symptoms (14%), dyspepsia (11%), paresis (10%), diarrhea (6%), pruritus (6%), and dermatological symptoms (3%). While symptom prevalence was influenced by tumor site, pain intensity, and opioid treatment, only a minor relationship was seen between symptoms and gender, age, or tumor stage. The data emphasize that it is not sufficient to simply address pain during the treatment of patients with cancer pain; a more global approach to symptom management is necessary.

Dyslipidaemia may be treated with a number of safe and effective pharmacological agents that target specific lipid disorders through a variety of mechanisms. The bile-acid sequestrants--cholestyramine and colestipol--primarily decrease LDL cholesterol by binding bile acids, thereby decreasing intrahepatic cholesterol, and by increasing the activity of LDL receptors. Nicotinic acid lowers LDL cholesterol and triglyceride by decreasing VLDL synthesis and by decreasing free fatty acid mobilization from peripheral adipocytes. The HMG-CoA reductase inhibitors--fluvastatin, lovastatin, pravastatin and simvastatin--lower LDL cholesterol by partially inhibiting HMG-CoA reductase (the rate-limiting enzyme of cholesterol biosynthesis) and by increasing the activity of LDL receptors. The fibric-acid derivatives--bezafibrate, ciprofibrate, clofibrate, fenofibrate and gemfibrozil--primarily decrease triglyceride by increasing lipoprotein lipase activity and by decreasing the release of free fatty acids from peripheral adipose tissue. Probucol decreases LDL cholesterol by increasing non-receptor-mediated LDL clearance; as an anti-oxidant, probucol also decreases LDL oxidation; oxidized LDL which is thought to lead to atherogenesis. Although these agents have been proven safe in clinical trials, like any drug, they carry the risk for adverse effects. The bile-acid sequestrants may cause constipation, reflux oesophagitis, and dyspepsia, and may bind coadministered medications such as digitalis glycosides, beta blockers, warfarin, and exogenous thyroid hormone. Nicotinic acid use is commonly associated with flushing and pruritus and may also cause non-specific gastrointestinal complaints, hepatotoxicity (hepatic necrosis, hepatitis, or elevated liver enzymes), gout, myolysis, decreased glucose tolerance and increased fasting glucose levels, and ophthalmological complications including decreased visual acuity, toxic amblyopia, and cystic maculopathy. The HMG-CoA reductase inhibitors may produce liver enzyme elevations, creatine kinase elevations and rhabdomyolysis. The combination of a reductase inhibitor and a fibrate increases the risk for rhabdomyolysis. Possible adverse effects of the fibric-acid derivatives include abdominal discomfort, nausea, flatulence, increased lithogenicity of bile, liver enzyme elevations and creatine kinase elevations. Probucol may increase the QTc interval and may cause non-specific gastrointestinal complaints.

The treatment of anemia in hemodialysis patients is frequently hindered by the presence of suboptimal iron stores. Intravenous iron dextran is in common use to maintain iron stores in this population, but there are little published data regarding the incidence and type of adverse events. The purpose of this study was to evaluate the safety of this medication. Charts from four hemodialysis centers of all 573 patients treated with intravenous iron dextran (INFeD; Schein Pharmaceutical, Inc, Florham Park, NJ) between July 1, 1993, and June 30, 1995, were studied. Twenty-seven patients (4.7%) had adverse reactions that were related to iron dextran. Four patients (0.7%) had reactions classified as serious (one cardiac arrest; three others required hospitalization). Ten patients (1.7%) had reactions classified as anaphylactoid. No patients died or developed permanent disability as a result of reactions. The most common adverse reactions included itching (1.5% of patients) and dyspnea or wheezing (1.5%); others included chest pain (1.0%), nausea (0.5%), hypotension (0.5%), swelling (0.5%), dyspepsia (0.5%), diarrhea (0.5%), skin flushing (0.3%), headache (0.3%), cardiac arrest (0.2%), and myalgias (0.2%). Five of all the reactions occurred during a test dose; four of these were anaphylactoid. Several factors were studied as possible predictors of adverse reactions. A positive history of drug allergy (odds ratio, 2.4; P = 0.03) and history of multiple drug allergy (odds ratio, 5.5; P = 0.0004) were significant predictors of reactions. In summary, we found serious adverse reactions to be uncommon in hemodialysis patients treated with intravenous iron dextran. Future prospective studies will help confirm this finding.

Couvade is a phenomenon, where the expectant father or another relative experiences somatic and/or psychiatric symptoms during a woman's pregnancy. Although epidemiological studies report a frequency of couvade symptoms between 11 and 36% during all pregnancies, psychotic couvade cases are very rare with few case reports. The authors report 2 cases of psychotic couvade and give a psychodynamic interpretation of the cases. They emphasize the important role of ego defect and double identification in the development of the cases. Couvade is a phenomenon, where the expectant father or another relative experiences somatic and/or psychiatric symptoms during a woman's pregnancy. The term couvade was first coined by Tylor in 1865. Somatic symptoms can include indigestion or colic, gastritic symptoms, food cravings, nausea and vomiting, increased or decreased appetite, diarrhea, toothache, headache, itch, muscle tremors, nosebleed or other pains. Abdominal bloating and pseudocyesis have also been reported. Although the psychiatric symptoms most often observed are depression, anxiety, insomnia, irritability, tension and hypochondria there are some reports on psychotic couvade too. In our article we present 2 cases of psychotic couvade.
