More than 1200 patients who received pindolol for the treatment of hypertension, angina pectoris, and various arrhythmias in studies conducted in the United States were included in the New Drug Application submitted to the FDA. Nearly 1000 of these patients received pindolol as monotherapy. The side effects reported were generally transient and of mild or moderate severity. The most frequently reported side effects seen after pindolol administration, compared to those seen after placebo, were in decreasing order of incidence: headache, dizziness, insomnia, muscle pain, fatigue, weakness, nervousness, joint pain, edema, nausea, and muscle cramps. Other side effects that occurred more frequently with pindolol than with placebo but at a rather low incidence induced weight gain, bizarre dreams, visual disturbances, lethargy, and diarrhea. Nasal congestion, throat discomfort, nocturia, impotence, pruritus, anxiety, hypotension, bradycardia, and heart failure occurred only rarely. Of the 323 patients who received pindolol alone for the treatment of mild to moderate hypertension, only 20 (6.2%) were withdrawn from the study because of side effects. Overall, 3.4% of the patients treated with pindolol were withdrawn because of side effects, most of which involved the central nervous system, that is, insomnia, anxiety, dizziness, and headache. However, a few patients manifested some edema and weight gain while receiving pindolol alone. Review of the side effects data did not reveal a tendency for the incidence of side effects to be dose related. One placebo-controlled, double-blind study designed to evaluate the fixed dosages of 15, 30, and 60 mg in the treatment of mild to moderate hypertension suggested that only the incidences of insomnia and nervousness increased with increasing doses. However, these side effects were generally transient and of mild or moderate severity. The evidence indicates that pindolol has an acceptable safety profile and that any side effects that appear are generally well tolerated and disappear with continued treatment.

Urticaria may be the only cutaneous manifestation of a leukocytoclastic vasculitis. We have studied nine patients with urticarial vasculitis.The spectrum ranged from limited cutaneous disease (six cases) to severe systemic disease with renal failure (one case). The individual urticarial lesions were of long duration (over 4h) in all patients and in seven cases an ecchymotic stain was left when the urticaria resolved. All patients complained of moderate to severe pruritus. Associated findings included arthralgia (two cases), fever (one case) and glomerulonephritis (one case), but none had neurological disease, abdominal pain or arthritis. Therapy was difficult in seven patients, and these cases were controlled only with systemic corticosteroids. This disorder falls within the larger group of vasculitides. It is distinguished only by its skin lesions, which cannot always be distinguished clinically from common urticaria.

Quinolones, elective drugs for Pseudomonas aeruginosa (P. aeruginosa) pulmonary infections in Cystic Fibrosis (C.F.) patients, are controversially administered in prepuberal age for their arthropathic toxicity. We report the result of retrospective study on the use of quinolones in a group of 43 CF patients. The patients were divided into two groups: below 18 years (22 pts.) and over 18 (21 pts.). All patients were evaluated clinically with the scoring system Shwachman and Kulczyk. Ciprofloxacin and Ofloxacin (15/20 mg/kg/die) were administered. In 11.6% of the patients, all belonging to the second group, side effects, such as urticaria, tongue oedema, foreskin erythema, generalised erythema and itch, were described. No side effect has been reported in the patients below 18 years. Two patients complained knee arthralgias not related to the quinolones administration: in fact in the first case the demineralisation seemed to be responsible of the arthralgia, while in the second case an immunological disorder (ANA+, ICC+) should be involved in the pathogenesis of arthritis. Height velocity evaluation showed the same slowering of the CF untreated patients. In conclusion, our study confirms that quinolones use in indicated in severe and infective complications of CF on the basis of their efficacy, safety and their slight adverse effects similar to those of other potent antibiotic. Moreover our results confirm that no quinolone-induced cartilage toxicity is present in CF patients.

We review the charts of the hospital with diagnostic of acute viral hepatitis. We classified them using serologic markers in hepatitis B (60 patients), hepatitis A (27 patients) and C (4 patients). Fatigue, anorexia, fever, chills and lymphadenopathy where more common in hepatitis A. Arthralgias, pruritus and rash where more common in hepatitis B. Bilirubin levels where higher in patients with hepatitis B (10.3 = -6.04 S.E:0.80) and C (9.7 +/- 4.09 S.E:1.24) compared with hepatitis A (6.7 +/- 6.04 S.E:0.80) p < 0.01 and p < 0.05. Alamine-Aminotransferase (ALT) levels where higher in patients with hepatitis B (1.918 +/- 1.099 S.E:215.5) and hepatitis A (1879 +/- 1.099 S.E:215.5) and lower in hepatitis C (988 +/- 764 E.E:382) p < 0.05. Abdominal Ultrasound reveal splenomegaly in 45% and 50% of patients with hepatitis A and C and only in 15% of patients with hepatitis B. Changes in gallbladder wall where found in 50% of patients with hepatitis A. 3.3% of patients with hepatitis B and 75% of patients with hepatitis C developed chronic infection.

In the last ten years ivermectin appeared an efficient and safe alternative to diethylcarbamazine which is known to induce severe adverse reactions in loiasis, including encephalitis. After these results, large scale ivermectin treatments against onchocerciasis were carried out in Central Africa where loiasis is also endemic; and seven cases of severe reaction were reported in Cameroon since 1991, during these mass ivermectin treatments. In order to study adverse reactions in patients harbouring high load of Loa loa microfilariae (mf), we realized careful hospital based treatment in 112 patients with more than 3,000 mf/ml (ml) blood. Patients received once 200 micrograms ivermectin per kilogram at day 0 (D0). Clinical examination was made daily during the four following days (D1 to D4). Blood and urine samples were analysed before treatment and at D1 and D3. Lumbar puncture was made at D1 for 39 patients with more than 10,000 mf/ml; at D3 for the 49 following patients without consideration for the level of parasitaemia, and at D0 and D3 for ten voluntary patients. For analysis the patients were distributed in 3 groups according to initial parasitaemia: the first group included 50% out of the patients, those whose parasitaemia was fewer than 15,000 mf/ml blood; the second group included 25% patients whose parasitaemia was between 15,000 and 30,000 mf/ml; the third group included the last 25% patients whose parasitaemia was higher than 30,000 mf per ml blood. Adverse reactions were observed in 71% out of the patients. Symptoms described were fever, pruritus, headache, arthralgia. Most symptoms appeared 24 to 36 hours after treatment. Temperature increased significantly in group 3. Microfilaraemia decreased by 85% in the 3 groups during the 4 days following treatment. C-reactive-protein increased dramatically after treatment in all patients (p < 10(-4)). Some patients presented blood in urine in three groups but haematuria reached 35% of patients in group 3. Proteinuria is noted among 33% of all patients but 20% in group 1 and 2 versus 70% in group 3. Loa loa mf were observed in urine of half the patients, but in low amounts (< 10 mf per 50 ml urine). In cerebro-spinal fluid (CSF), some mf appeared at D1 or D3 in people heavily infected with Loa loa, reaching 80% of the patients of group 3. LP made at D0 in ten patients with parasitaemia higher than 30,000 mf/ml blood confirmed that CSF was naturally microfilaria free before treatment. One patient presented severe troubles with fever, asthenia and conscience troubles beginning at D3, reactive coma at D4, renal impairment with transitory anuria; progressive improvement in 2 weeks and complete recovery at D22; he presented 102 mf/ml CSF at D6. The study confirmed that ivermectin treatment is generally well tolerated. Among people with high Loa loa parasitaemia the symptoms after treatment are frequent but mild. However severe cases with conscience troubles are possible, and may occur in about 1% of subjects with more than 3,000 mf/ml blood. Severity of adverse reactions was linked to level of parasitaemia before treatment. The critical parasitaemia level which could lead to expect serious adverse effects seems to be 30,000 ml/ml blood. These informations should induce carefulness to carry out large scale treatments against filariosis in endemic areas of Loa loa.

We report a case of drug eruption caused by the crude drug Boi. A 41-year-old female patient had been diagnosed with chronic rheumatoid arthritis in the department of internal medicine. After ingestion of a decoction of the crude drug Boi for the alleviation of arthralgia, a slight fever developed, which was followed by systemic edematous erythema with itching. HPLC showed that the main components of the crude drug Boi are sinomenine and magnoflorine. The results of patch tests were negative for all oral drugs that the patient had been taking. Oral ingestion tests showed that the patient showed positive reactions to the as-is Boi boiling-water decoction and 1/10-volume sinomenine. Based on this, the drug eruption was judged to be caused by sinomenine. It is considered the first time that the causative component of a drug eruption was confirmed by oral ingestion tests with components of a crude drug of Kampo medicine (Sino-Japanese traditional medicine).

Because of the difficulty and expense of objectively measuring psoriasis severity, very little information exists on the severity of psoriasis in populations. We determined severity in a psoriasis patient population using the validated self-administered psoriasis area and severity index (SAPASI). This population consisted of 578 university dermatology clinic psoriasis patients, and data were analyzed from 317 (55%) questionnaire respondents. The majority of our sample was women (57%), and non-Caucasians represented a larger portion (8 %) in our sample compared with some previous studies. In our population, the reported frequencies of skin and joint symptoms were as follows: pruritus (95 %), skin burning (81 %), joint pain (69%), arthritis (51%), and psoriatic arthritis (20%). The SAPASI was significantly associated with severity of pruritus, burning, joint pain, and psoriatic arthritis. There was a significant negative correlation between the number of treatments employed and the SAPASI. This study provides results of a detailed measurement of the severity of psoriasis in a psoriasis patient population and relates this severity to population characteristics.

High molecular weight (MW) solutes are not removed during conventional hemodialysis (HD), and their accumulation is thought to play a role in some long-term HD complications (anemia, bone and joint pain, neuropathy, itching). The present trial was conducted to evaluate the removal capacity during in vivo HD of a new polymethylmethacrylate (PMMA) membrane (Filtryzer BK-F, 1.3 m2) compared to conventional PMMA (BK-P, 1.6 m2) and to cellulose acetate (CA, 1.3 m2). BK-F dialyzers, with a pore size of 100 A degrees and 62% porosity, are designed to remove high MW substances. Ten stable anuric RDT patients (53 +/- 13 years) were treated for one week with each membrane in a randomized sequence. Plasma concentrations of creatinine, BUN and beta 2-microglobulin (beta 2-M) were measured before (b) and after (a) HD to determine the reduction rate for these substances (%). Beta 2-M concentration after HD was corrected for changes in distribution volume. Samples of spent dialysate were collected after 3 minutes, 120 minutes and at the end of HD sessions, and appropriately treated and concentrated for HPLC analysis. The reduction rate for BUN and creatinine was similar for the 3 membranes. BK-F showed a higher beta 2-M reduction rate than BK-P (p < 0.005) or CA (p < 0.0001). HPLC analysis of dialysate showed prevalent peaks < 4 kilodaltons (kDa) throughout HD for BK-P and CA. Solutes > 10 kDa were infrequently detected. Peak profile during HD with BK-F was quite different, showing a predominant peak > 50 kDa which also included albumin. However, albumin loss significantly decreased after 120 minutes and at the end of dialysis compared with the 3-minute values, and was lower than that reported in CAPD patients. With BK-F a peak of MW > 500 kDa was also detected which previous studies indicated as a range characterized by the presence of erythropoiesis inhibitors. Use of the BK-F membrane in HD could afford satisfactory removal of high MW substances, thereby preventing or controlling some long-term HD complications such as anemia or beta 2-M amyloid formation.

In 1994, we isolated Borrelia burgdorferi sensu lato from 231 patients with erythema migrans who presented to the University Medical Center in Ljubljana, Slovenia. Samples of erythema migrans-affected skin were placed in media to support the growth of Borrelia species and evaluated in Ljubljana and Chicago. Patients whose cultures were positive included 132 women and 99 men; 136 of these 231 patients recalled a tick bite. Patients noted a rash an average of 24 days after a bite and presented a mean of 34 days after the bite with erythema migrans (mean diameter. 16 cm). Itching (44%) burning (18%), and pain (11%) were the most common local symptoms. Systemic complaints (40%) included headache, fatigue, malaise, and arthralgia. Other than erythema migrans, findings on physical examination were minimal (< 5% had fever, and in < 10% local lymph nodes were affected). Serial serological studies using indirect immunofluorescence assay, ELISA, and Western blot methods were performed, and antibodies to B, burgdorferi sensu lato were detected in < 50% of samples from patients. This is the largest series reported to date of patients with culture-confirmed Lyme borreliosis. It highlights the deficiencies of serological tests in early disease, demonstrates the sensitivity of direct detection methods for evaluation of patients with erythema migrans, and suggests that patients with early Lyme borreliosis in Slovenia may suffer a milder illness than those in the United States.

Secondary hyperparathyroidism is a common complication of chronic renal disease. Clinical signs and symptoms tend to be severe and often are not controlled with medical measures. When medical therapy fails, parathyroidectomy becomes necessary. Recurrent hyperparathyroidism is not uncommon following surgery. One cause of surgical failure is parathyromatosis, which has been described as multiple nodules of hyperfunctioning parathyroid tissue scattered throughout the lower neck, superior mediastinum, or the arm if autotransplantation has been performed. Five cases of parathyromatosis in patients with chronic renal failure were identified. Clinical characteristics, course, and prognosis of the patients are reported. All patients had evidence of renal osteodystrophy and complained of severe pruritus and bone and/or joint pain. Three of the five patients had evidence of soft tissue calcification, two complained of muscle weakness, two had multiple fractures, and two eventually died of complications resulting from parathyromatosis. In four of five cases, surgical and medical management were ineffective. The patients described illustrate the severe morbidity and mortality associated with the parathyromatosis in the setting of end-stage renal disease. The pathogenesis remains controversial. Although primary prevention appears to be the most effective means of avoiding this complication, it is mandatory that meticulous care be taken during surgical manipulation. If such measures fail, calcium supplementation, calcitriol, and phosphate restriction may be tried.
