Bromocriptine in systemic lupus erythematosus: a double-blind, randomized, placebo-controlled study

The objective of this study was to investigate the efficacy and safety of bromocriptine (BRC) as an adjunct to conventional treatment in systemic lupus erythematosus (SLE). A prospective, double-blind, randomized, placebo-controlled study compared BRC at a fixed daily dosage of 2.5 mg with placebo. Patients were followed for 2-17 months (mean 12.5 months). Disease activity was assessed using the SLE Disease Activity Index (SLEDAI), numbers of flares were recorded, and serum prolactin (PRL) levels were obtained at intervals during the study. Patients were allowed to take prednisone and immunosuppressive drugs. Sixty-six patients with SLE entered the study. Thirty-six were treated with BRC, and 30 controls received placebo. Sixteen patients were removed from the study during the treatment period: five in each group left the study because of adverse effects, five became pregnant, and one patient who took placebo died with central nervous system lupus. Four patients in the BRC treatment group and three patients in the placebo group moved away or stopped coming for study visits for unknown reasons, and were lost to follow-up during the course. At entry, serum PRL was (mean+/-s.d.) 24.8 ng/ml+/-18.4 in the BRC treatment group. This value fell to 5.8+/-9.0 after 12 months of treatment. Corresponding PRL values in controls were 23.7+/-22.1 pretreatment and 20.3+/-14 after 12 months. PRL levels in BRC-treated subjects were significantly lower than levels in control subjects after 3, 6, 9, and 12 months of treatment. The SLEDAI score on the fifth protocol visit was decreased significantly in the BRC group vs controls: 0.9+/-1.4 vs 2.6+/-4.5 (P < 0.05). Although the absolute number of flares in each group was similar, the mean number of flares/patient/month was decreased significantly in the BRC group compared to the control group (0.08+/-0.1 vs 0.18+/-0.2, P = 0.03). Long term treatment with a low dose of BRC appears to be a safe and effective means of decreasing SLE flares in SLE patients.     

Prevention of supraventricular tachyarrhythmias after open heart operation by low-dose sotalol: a prospective, double-blind, randomized, placebo-controlled study

BACKGROUND: The aim of this prospective, double-blind, placebo-controlled trial was to assess the preventive effect and safety of low-dose sotalol after heart operation. METHODS: Two hundred fifty-five consecutive patients referred for elective coronary artery bypass grafting (n = 220) or aortic valve operation (n = 35) were randomized to receive either 80 mg of sotalol twice daily (n = 126) or matching placebo (n = 129) for 3 months, with the first dose given 2 hours before operation. RESULTS: There were no significant baseline differences between the groups. Overall, supraventricular tachyarrhythmias occurred in 36% of patients (82% atrial fibrillation). Hospital stay was 11.6 +/- 5 days in patients with supraventricular arrhythmias, versus 9.5 +/- 2.4 days in patients without it (p < 0.0001). Low-dose sotalol reduced the rate of supraventricular arrhythmias from 46% (placebo) to 26% (sotalol; p = 0.0012), or by 43%. On the fourth postoperative day, heart rate was lower in the sotalol group (74 +/- 12 beats/min versus 85 +/- 15 beats/min; p < 0.0001) but the QT interval corrected for the heart rate was not prolonged (sotalol group, 0.44 +/- 0.03 second; placebo group, 0.43 +/- 0.03 second; p = not significant). Study medication had to be discontinued because of side effects in 5.6% of sotalol and 3.9% of placebo patients (p = not significant), with one possible proarrhythmic event occurring in a patient receiving sotalol. CONCLUSIONS: Because more than 90% of supraventricular arrhythmic episodes occurred within 9 days after operation and 70% of all possibly sotalol related side effects occurred after day 9, the findings in this study imply that prophylactic treatment with sotalol may be limited to the first 9 postoperative days.     

S-fluoxetine in the prophylaxis of migraine: a phase II double-blind randomized placebo-controlled study

A tubular bioassay was used to measure analytically the local production and concentration of the antifungal Trichoderma secondary metabolite 6-n-pentyl-2H-pyran-2-one (6PAP) at the Trichoderma antagonist/pathogen interface. 6PAP levels significantly increased in the presence of the pathogen Botrytis cinerea, typically 300-700%, and were highest near the pathogen source. The level of response for a particular Trichoderma isolate was found to vary with the test organism used. Two products produced by biotransformation of 6PAP by B. cinerea in response to the interaction were also detected.     

Loop diuretics in the management of acute renal failure: a prospective, double-blind, placebo-controlled, randomized study

BACKGROUND: Studies on the role of loop diuretics in patients with acute renal failure (ARF) are largely retrospective, anecdotal, and poorly controlled. We report the results of a prospective, randomized, placebo-controlled, double-blind study examining the effect of loop diuretics on renal recovery, dialysis, and death in patients with ARF. METHODS: Ninety-two patients with ARF were enrolled into the study. All received intravenous dopamine, 2 micrograms/kg body weight/min throughout, 20% mannitol, 100 ml every 6 h for the first 3 days, and, in a double-blind manner, either torasemide, frusemide, or placebo, 3 mg/kg body weight i.v. every 6 h for 21 days or until renal recovery or death. RESULTS: Renal recovery, the need for dialysis, and death were no different in the three groups. Patients given a loop diuretic had a significant rise in urine flow rate in the first 24 h compared to placebo (P = 0.02). Based on the urine flow rate during the first post-medication day patients were divided into two groups--oliguric (< 50 ml/h) and non-oliguric (> or = 50 ml/h). Non-oliguric patients had a significantly lower mortality than oliguric patients (43% vs 69%, P = 0.01). However, they were less ill (APACHE II score 17.2 vs 20.6, P = 0.008) and had less severe renal failure at entry (creatinine clearance 14 ml/min vs 4 ml/min, P < 0.0001). CONCLUSION: The use of loop diuretics in oliguric patients with ARF can result in a diuresis. There is no evidence that these drugs can alter outcome.     

Effect of piracetam on recovery and rehabilitation after stroke: a double-blind, placebo-controlled study

The nootropic agent piracetam has been shown to improve learning and memory, and it may, by this means, facilitate recovery and rehabilitation after a stroke. We report the results of a pilot study exploring its effects in patients undergoing rehabilitation after acute cerebral infarction in the carotid artery territory. We compared piracetam and placebo, each given for 12 weeks, in a multicenter, double-blind, randomized trial of parallel-group design; testing was performed at baseline (6-9 weeks poststroke), weeks 5 and 12, and, in fewer patients, 12 weeks after termination of treatment. Standardized tests of activities of daily living (Barthel Index, Kuriansky Test), aphasia (Aachen Aphasia Test), and perception (Rivermead Perception Assessment Battery) were the primary efficacy variables. Of 158 patients, 137 (81 males, 56 females) were studied after treatment and 88 at 24-week follow-up. Thirty patients on piracetam (45%) and 37 on placebo (53%) were aphasic on entry. Both groups, including the subgroups with aphasia, were well matched at baseline for demographic data, stroke sequelae, type and severity of aphasia, and prognostic parameters. Multivariate analysis of Aachen Aphasia subtest scores showed a significant overall improvement relative to baseline in favor of piracetam (p = 0.02) at 12 weeks. This was not seen at 24 weeks when, however, fewer patients were available for evaluation so that we could neither confirm nor deny whether improvement was maintained after cessation of piracetam. We were unable to demonstrate an effect on tests of activities of daily living and could neither confirm nor exclude an effect on perceptual deficit. We have shown an improvement in aphasia in patients undergoing rehabilitation after a stroke after 12 weeks' treatment with piracetam that requires confirmation in further studies.     

Corticosteroids in the treatment of tuberculous pleurisy. A double-blind, placebo-controlled, randomized study

Although several studies on tuberculous (TB) pleurisy suggest that the addition of corticosteroids to anti-TB therapy may have beneficial effects, these agents are not used routinely. To assess the effects of short-term oral prednisone therapy in TB pleurisy, 74 patients were randomly assigned in a double-blind fashion to treatment with either placebo or prednisone at a dose of 0.75 mg/kg/d for up to 4 weeks with gradual reduction over an additional 2 weeks. All subjects received a standard 3-drug anti-TB chemotherapy regimen for 6 months. TB pleurisy was diagnosed by histologic study and/or culture of pleural biopsy specimens obtained at thoracoscopy. Complete drainage of the effusion was performed simultaneously. Outcome measures were assessed periodically for 24 weeks, including indexes of morbidity and pleural thickening. After randomization, four patients were excluded from the final analysis. Of the 70 patients analyzed, 34 received prednisone and 36 received placebo. Demographic and clinical characteristics of the treatment groups were comparable at the time of hospital admission. Although a statistically significant improvement in symptoms occurred earlier in the prednisone group (8 weeks) than in the placebo group (12 weeks), between-group comparison showed no significant differences at any of the follow-up evaluations. The proportion of subjects in the prednisone group (53.1%) with residual pleural thickening at 6 months did not differ significantly from that of the placebo group (60%). Pleural effusions did not recur in any of the patients. Initial complete drainage of the effusion was associated with greater symptomatic improvement than any subsequent therapy. We conclude that standard anti-TB therapy and early complete drainage is adequate for the treatment of TB pleurisy. The addition of short-term oral prednisone therapy neither results in clinically relevant earlier symptom relief nor confers a beneficial effect on residual pleural thickening.     

Clonidine for major vascular surgery in hypertensive patients: a double-blind, controlled, randomized study

The utility of clonidine for hypertensive patients presenting for major vascular procedures remains debatable. Twenty-one hypertensive patients presenting for aortic surgery were given clonidine (n = 11) or placebo (n = 10) in a double-blind, randomized manner. Clonidine was administered 6 micrograms/kg per os 120 min before induction of anesthesia and 3 micrograms/kg intravenously (i.v.) over 60 min from aortic declamping to skin closure. Anesthesia was induced with alfentanil 20 micrograms/kg, midazolam, and atracurium and maintained with nitrous oxide 70%, an alfentanil infusion (0.25 microgram.kg-1. min-1), and isoflurane. Anesthetic requirements, circulatory variables, interventions, and isoproterenol dose-response curves (pre- and postoperatively) were determined. Plasma concentrations of clonidine, alfentanil, and vasoactive hormones were measured. When the clonidine group was compared with the placebo group, (a) isoflurane, alfentanil, and midazolam requirements were reduced by 38%, 42%, and 41%, respectively (P = 0.04, 0.03, 0.0002, respectively); (b) supplemental circulatory and anesthetic adjustments were reduced by 51% (P = 0.0006); (c) interventions with vasopressors were not significantly increased (placebo: two; clonidine: five); (d) systolic and mean arterial pressures and heart rate were reduced; (e) increases in norepinephrine, epinephrine, and plasma renin activity were suppressed, whereas vasopressin surge was attenuated; and (f) chronotropic response to isoproterenol was unaffected. Clonidine was effective in reducing anesthetic requirements and in improving circulatory stability in hypertensive patients presenting for major vascular procedures.     

Recombinant interferon-alpha therapy for acute hepatitis B: a randomized, double-blind, placebo-controlled trial

In spite of the availability of hepatitis B vaccine, acute hepatitis B continues to be a worldwide problem for which no specific therapy is available. We investigated the safety and the effectiveness of recombinant interferon-alpha2b (rIFN-alpha2b) in the treatment of acute hepatitis B by determining overall severity and duration of symptoms, time required to clear viral antigens and hepatitis B virus (HBV) DNA, and titre of antibodies to hepatitis B surface antigen (HBsAb), 24 weeks after the onset of therapy. One hundred patients were randomly assigned to treatment with either 3 million units (MU) (n = 34) or 10 MU (n = 33) rIFN-alpha2b or to placebo (n = 33), three times weekly for 3 weeks. Follow-up was for 24 weeks. A significantly shorter duration of the symptoms and signs of acute hepatitis was observed in patients who received 3 MU rIFN-alpha2b compared with those who received 10 MU rIFN-alpha2b or placebo. Twenty-one weeks post-therapy, patients treated with 10 MU rIFN-alpha2b showed a significantly higher geometric mean HBsAb titre than those treated with placebo (85.1 vs 35.5 IU l-1, P < 0.05). rIFN-alpha2b administration was well tolerated even in jaundiced patients. No serious side-effects were observed necessitating reduction in dose or discontinuation of the drug. The effect of rIFN-alpha2b on transition of HBV infection to chronicity could not be evaluated in this trial because such an unfavourable course was not seen in any of the treated or the control patients. In conclusion, rIFN-alpha2b was safe in acute hepatitis B, and at low dose was found to ameliorate symptoms and to shorten significantly the duration of illness.     

Prophylactic iron supplementation after Roux-en-Y gastric bypass: a prospective, double-blind, randomized study

OBJECTIVE: To determine whether prophylactic oral iron supplements (320 mg twice daily) would protect women from iron deficiency and anemia after Roux-en-Y gastric bypass. DESIGN: Prospective, double-blind, randomized study in which 29 patients received oral iron and 27 patients received a placebo beginning 1 month after Roux-en-Y gastric bypass. SETTING: Tertiary care medical center. PATIENTS AND INTERVENTIONS: Complete blood cell count and serum levels of iron, total iron binding capacity, ferritin, vitamin B12, and folate were determined preoperatively and at 6-month intervals postoperatively in 56 menstruating women who had Roux-en-Y gastric bypass. MAIN OUTCOME MEASURE: Incidence of iron deficiency and other hematological abnormalities in each treatment group. RESULTS: Hemoglobin, hematocrit, and vitamin B12 levels were significantly decreased compared with preoperative values in both groups. Conversely, folate levels increased significantly over time in both groups. Oral iron consistently prevented development of iron deficiency in the iron group. Ferritin levels did not change significantly in the iron group. However, in placebo-treated patients, ferritin levels 2 years postoperatively were significantly decreased compared with preoperative levels. There was no difference in the incidence of anemia between the 2 groups. However, the incidence of microcytosis was substantially greater (P=.07) in placebo-treated than iron-treated patients. CONCLUSIONS: Prophylactic oral iron supplements successfully prevented iron deficiency in menstruating women after Roux-en-Y gastric bypass but did not consistently protect these women from developing anemia. On the basis of these results we now routinely recommend prophylactic iron supplements to menstruating women who have Roux-en-Y gastric bypass.     

Treatment of inclusion-body myositis with IVIg: a double-blind, placebo-controlled study

The hypothesis was tested that 7-sulfooxymethylbenz[a]anthracene (7-SBA) is an ultimate electrophilic and carcinogenic form of 7-hydroxymethylbenz[a]anthracene. In conformity with this hypothesis, 7-SBA was more carcinogenic than 7-HBA in inducing sarcomas at the site of repeated subcutaneous injection. These metabolites were individually administered to female Sprague-Dawley rats, beginning at 30 days of age, in 0.2 mumol doses given three times each week for 20 doses. One year after the first injection of 7-SBA, seven of thirteen female Sprague-Dawley rats had developed sarcomas. 7-HBA, on the other hand, had induced sarcomas at the site of injection in only two of tweleve rats. No tumors developed either in the control group given sesame oil:DMSO only or in the untreated control group. It would appear from the results summarized here that the search for an ultimate electrophilic and carcinogenic form of 7-HBA has been successful.     

Prospective, randomized, double-blind study of high-dose aprotinin in pediatric cardiac operations

OBJECTIVE: To describe the characteristic cytologic features of fine needle aspirates (FNAs) of primary extragonadal germ cell tumors (PEGCTs). STUDY DESIGN: Thirteen patients with PEGCTs, including 2 seminomas, 2 mixed germ cell tumors, 3 immature teratomas, 1 choriocarcinoma and 5 yolk sac tumors (YSTs) were studied. The final diagnosis of PEGCT in all cases was established by histologic examination of the tumor tissues. Fine needle aspiration was done on either the primary tumor or metastatic foci. The aspirates were stained with one of the Romanovsky stains and Papanicolaou stain. RESULTS: Each type of PEGCT has its own morphologic characteristics. In seminoma, the tumor cells are large and noncohesive, with one to several distinct nucleoli; some lymphocytes are also present. YSTs show many pleomorphic cells with vacuoles in the cytoplasm and nuclei; tumor cells frequently aggregate in a microglandular or papillary pattern. Choriocarcinoma consists of syncytiotrophoblasts and cytotrophoblasts. The former are very large cells with eosinophilic cytoplasm, one to several nuclei and distinct nucleoli; the latter are medium-sized cells with vacuolated, basophilic cytoplasm and eccentric nuclei. Immature teratomas are composed of a mixture of cell types, including elongated epithelioid cells, mesenchymal cells and many large, naked, amorphous nuclei with a homogeneous chromatin pattern. Diagnosis of mixed germ cell tumor is difficult but can be made if two or more subtypes of tumor cells are observed in the FNA. CONCLUSION: Cytologic examination of FNAs of primary or metastatic lesions of PEGCTs, stained either with Romanovsky or Papanicolaou stain, is of diagnostic value for such diseases. The use of immunochemistry can help to confirm the cytologic impression.     

Bismuth carbomer foam enemas for active chronic pouchitis: a randomized, double-blind, placebo-controlled trial

One biological effect of nitric oxide (NO) has been believed to be exerted through induction of the ADP-ribosyltransferase activity of glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Though this notion is based on the finding that NO increases the auto-ADP-ribosylation of GAPDH, controversial data have also been reported. To determine whether or not NO really activates ADP-ribosylation, we re-examined the NO-induced modification of GAPDH with NAD+. GAPDH was modified equally with [adenosine-14C]NAD+ and [carbonyl-14C]NAD+, indicating that the glycoside bond of NAD+ between ADP-ribose and nicotinamide is intact. The release of nicotinamide from NAD+ was not evident during incubation of GAPDH with [carbonyl-14C]NAD+. Thus, the modification of GAPDH is apparently not ADP-ribosylation. In addition, we found that basal and glyceraldehyde-3-phosphate-induced modifications of GAPDH, both of which have also been explained as ADP-ribosylation, were not ADP-ribosylation, and that the modification of GAPDH in the absence and presence of NO or GA3P was distinct in the dithiothreitol effect or resistance to HgCl2.     

Effect of nicotine nasal spray on smoking cessation. A randomized, placebo-controlled, double-blind study

BACKGROUND: Nicotine replacement therapies have proved to be of value in smoking cessation. However, not all smokers can use the nicotine gum or nicotine patch owing to side effects. In addition, the absorption of nicotine from these formulas is slow compared with smoking. A nicotine nasal spray delivers nicotine more rapidly. The objective of this study was to evaluate the efficacy and safety of the nicotine nasal spray for smoking cessation. METHODS: Subjects were recruited through advertisements in newspapers and among patients referred to the smoking cessation clinic at Sahlgren's Hospital, G?teborg, Sweden. Two hundred forty-eight smokers were treated in small groups with eight counseling sessions over 6 weeks. At their first group session, subjects were randomized to a group receiving nicotine spray (n = 125), 0.5 mg of nicotine per single spray, or to a placebo group (n = 123). The procedure was double blind. Success rates were measured up to 12 months. The nonsmoking status was verified by expired carbon monoxide less than 10 ppm. RESULTS: Significantly more subjects in the nicotine group were continuously abstinent for 12 months than in the placebo group (27% vs 15%; odds ratio, 2.16; 95% confidence interval, 1.15 to 4.12). Ten of the 34 abstinent subjects in the nicotine group used the spray for 1 year. Mild or moderate side effects were rather frequent for both sprays, but they were significantly more for the nicotine spray. Subjects with high scores (> 7) on Fagerstr?m's tolerance questionnaire had a significantly lower success rate with placebo than with the nicotine spray. For subjects with low scores, there was no difference. CONCLUSION: Nicotine nasal spray in combination with group treatment is an effective aid to smoking cessation.     

Sulphasalazine in psoriatic arthritis: a randomized, multicentre, placebo-controlled study

A prospective double-blind, placebo-controlled, randomized study of 24 weeks duration was carried out comparing the efficacy and tolerability of sulphasalazine (SSZ) versus placebo in patients with psoriatic arthritis. A total of 120 patients were included in nine centres. All patients had active disease and fulfilled the criteria of definite psoriatic arthritis of at least 3 months duration. They received either SSZ (2.0 g/day) or placebo. Efficacy variables included pain, patient's overall assessment of joint and skin improvement, morning stiffness, Ritchie articular index, ESR and CRP. An intention-to-treat (ITT) analysis was performed for the 117 patients who qualified (three patients did not qualify due to missing data after baseline). A per-protocol analysis was performed for the 81 patients who completed the 6 months study period (SSZ = 38, placebo = 43). Major reasons for withdrawal were inadequate response (SSZ = 4, placebo = 7) and adverse events (SSZ = 8, placebo = 12). Pain was the only statistically significantly different primary outcome variable at end point in favour of SSZ in the ITT analysis. No significant differences were present in other clinical or biological variables, although there was a trend in favour of SSZ for some variables. SSZ, at a dose of 2.0 g/day, appeared to be a safe treatment in patients with psoriatic arthritis. At this dosage, its efficacy was only demonstrated for the pain variable.     

Short-chain fatty acids in the treatment of radiation proctitis: a randomized, double-blind, placebo-controlled, cross-over pilot trial

PURPOSE: Treatment of chronic radiation proctitis remains unsatisfactory. Short-chain fatty acids are the preferred energy source for the colonic epithelium. We aimed to determine for the first time whether topical butyric acid enemas relieve symptoms and improve the macroscopic and microscopic findings in chronic radiation proctitis. METHODS: A randomized, double-blind, placebo-controlled, cross-over pilot trial compared patients given two weeks of butyric acid enemas (40 mmol) twice per day with those given placebo, with a one-week washout period; 15 patients were randomized and 12 completed both arms of the trial. A total symptom score combined six symptom items per week (rectal pain, episodes of rectal bleeding, amount of blood passed, days with diarrhea, number of stools, and urgency). Symptom, endoscopic, and histologic scores were obtained at the beginning of the study and again at the last week of each treatment arm. RESULTS: Total symptom score at baseline (median, 5.5) improved for those patients receiving active treatment (median, 3.5), but compared with placebo (median, 4.5), the change was not significant. Endoscopic appearances were largely unaltered by active treatment. Histology was abnormal in 82 percent of patients receiving placebo compared with 55 percent of those given butyric acid enemas (P = not significant). CONCLUSION: Butyric acid enemas do not appear to be superior to placebo in the treatment of chronic radiation proctitis.     

Sulfasalazine in the treatment of juvenile chronic arthritis: a randomized, double-blind, placebo-controlled, multicenter study. Dutch Juvenile Chronic Arthritis Study Group

AIMS: To determine whether left ventricular volumes and ejection fractions calculated from single plane two-dimensional echocardiograms using the algorithm (0.85A2L) correlate with those calculated using the biplane Simpson's method, and whether small changes in volumes and ejection fraction occurring post-infarction could be detected from single-plane as well as from biplane two-dimensional echocardiograms. METHODS AND RESULTS: Serial two-dimensional echocardiograms were obtained in 371 patients from the DEFIANT II trial a mean of 2 days, 1 week and 6 months post-infarction. Single plane volumes from the apical four chamber and apical long axis correlated closely with biplane Simpson's left ventricular volumes. Both single-plane left ventricular volumes significantly over-estimated biplane Simpson's volumes. Biplane Simpson's ejection fractions were consistently slightly under-estimated from the single-plane images. Differences between biplane Simpson's and single-plane volumes increased independently with increasing left ventricular size and distortion. The small changes in left ventricular volumes and ejection fraction over time were as reliably detected from single plane as from biplane images. CONCLUSION: Single-plane left ventricular volumes over-estimate biplane Simpson's volumes and under-estimate ejection fraction, and these discrepancies are amplified in dilated hearts with abnormal shape.     

Long-term treatment of ulcerative colitis with ciprofloxacin: a prospective, double-blind, placebo-controlled study

BACKGROUND & AIMS: Although bacterial bowel flora may be one of the contributing factors in the pathogenesis of chronic mucosal inflammation, antibiotic treatment has no established role in ulcerative colitis. The aim of the study was to evaluate the role of ciprofloxacin in the induction and maintenance of remission in ulcerative colitis in patients responding poorly to conventional therapy with steroids and mesalamine. METHODS: Ciprofloxacin (n = 38; 500-750 mg twice a day) or placebo (n = 45) was administered for 6 months in a double-blind, randomized study with a high but decreasing dose of prednisone and maintenance treatment with mesalamine including follow-up for the next 6 months. Clinical assessment and colonoscopic evaluation were performed at 0, 3, 6, and 12 months. Treatment failure, the primary end point, was defined as both symptomatic and endoscopic failure to respond. RESULTS: During the first 6 months, the treatment-failure rate was 21% in the ciprofloxacin-treated group and 44% in the placebo group (P = 0.02). Endoscopic and histological findings were used as secondary end points and showed better results in the ciprofloxacin group at 3 months but not at 6 months. CONCLUSIONS: Addition of a 6-month ciprofloxacin treatment for ulcerative colitis improved the results of conventional therapy with mesalamine and prednisone.     

Bathing suit delivery of 8-methoxypsoralen for psoriasis: a double-blind, placebo-controlled study

Twenty-four patients, 15 men and 9 women, aged 18-70 years with stable plaque-type psoriasis involving more than 20% of the body surface were subjected to a randomized, double-blind, age- and sex-matched, placebo-controlled study. Containers containing 25 mL of either 1% 8-MOP or a color-matched placebo were randomly numbered and stored. To 2 L of water was added 0.8 mL of 1% 8-MOP to obtain a concentration of 3.75 mg/L3, into which a bathing suit was soaked for 5 min. The suits were then gently squeezed to remove excess water and the patients were advised to put on the suit covered by a raincoat for 15 min. Immediately after removal of the raincoat and the suit, patients were irradiated with an initial dose of 4 J/cm2 UVA with increments of 0.5 J/cm2 on alternate days in a whole-body phototherapy unit obtained from the National Biological Corporation, Ohio. Erythema, scaling, and thickness (EST) of the index lesions were assessed on a 3-point scale (Table 1) and photographs were taken before and after completion of the study.     

Effect of adjuvant pindolol on the antiobsessional response to fluvoxamine: a double-blind, placebo-controlled study

In 1994, a Ph.D.-study started regarding pharmacy, organization and management (APOM) in the Netherlands. The APOM-project deals with the structuring and steering of pharmacy organization. This article describes a summary of the theoretical background of the project and the empirical results of a pilot study (n = 24). No generalization to the population of pharmacies in the Netherlands was made. Three mixes of objectives in pharmacy organization were theoretically postulated; the product mix, the process mix, and the customer mix. Mainly, the purpose of the pilot study was method selection. Additionally, it was studied if thought and action of pharmacy managers corresponded, and, if theoretical pharmacy mixes corresponded with the empirical pharmacy mixes. Two methods were selected to be applied in a survey. Thought and action did not correspond for most pharmacy managers. Thought related to customer and product mainly, and action related to process and customer mainly.
