All participating patients gave their written,informed consent. After inclusion, patients with acute symptoms of hemorrhoids were centrally randomized to receive, as outpatients, by the rectal route, suppositories of rSK 200000 IU of one unit every 8 h(first 3 units)and afterwards every 12 h until 8 administrations were completed(schedule A), one unit every 8 h until 6 units were completed(schedule B), or 25 mg hydrocortisone acetate once every 8 h up to a maximum of 24 administrations. Evaluations were performed at 3, 5,and 10 d post-inclusion. The main end-point was the 5thday response(disappearance of pain and bleeding, and≥ 70% reduction of the lesion size). Time to response and need for thrombectomy were secondary efficacy variables. Adverse events were also evaluated.RESULTS: Groups were homogeneous with regards to demographic and baseline characteristics. Fifth day complete response rates were 156/170(91.8%; 95%CI:87.3-96.2), 155/170(91.2%; 95%CI: 86.6%-95.7%),and 46/170(27.1%; 95%CI: 20.1%-34.0%) with rSK(schedule A and B) and hydrocortisone acetate suppositories, respectively. These 64.6% and 63.9%differences(95%CI: 56.7%-72.2% and 55.7%-72.0%)were highly significant(P < 0.001). This advantage was detected since the early 3rd day evaluation(68.8% and64.1% vs 7.1% for the rSK and active control groups,respectively; P < 0.001) and was maintained even at the late 10 th day assessment(97.1% and 93.5% vs67.1% for rSK and hydrocortisone acetate, respectively;P < 0.001). Time to response was 3 d(95%CI: 2.9-3.1)for both rSK groups and 10 d(95%CI: 9.3-10.7) in the hydrocortisone acetate group. This difference was highly significant(P < 0.001). All subgroup stratified analyses(with or without thrombosis and hemorrhoid classification) showed a statistically significant advantage for the rSK groups. Thrombectomy was necessary in4/251 and 14/133 patients with baseline thrombosis in the rSK and hydrocortisone acetate groups, respectively(P < 0.001). There were no adverse events attributable to the experimental treatment.CONCLUSION: rSK suppositories showed a significant advantage over a widely-used over-the-counter hydrocortisone acetate preparation for the treatment of acute hemorrhoidal illness, as well as having an adequate safety profile.展开更多

However, there is limited evidence of these ototoxic effects in humans. This is the first report to show the ototoxic effects of povidoneiodine in a human subject.Patient: A 36-year-old woman came to our hospital complaining of left unilateral persistent hearing loss. One month before presentation, her child had accidentally struck her on her left ear. She applied approximately three drops of povidone-iodine(10% weight/volume) into her left auditory canal. Immediately after application, she felt severe pain and vertigo. An audiogram revealed severe left unilateral sensorineural hearing loss. Magnetic resonance imaging showed mild enhancement of the left vestibule and basal turn of the left cochlea.Conclusions: Even a single application of povidone-iodine could cause significant hearing loss and disequilibrium. It should, therefore, be used with caution.展开更多

According to the record of ancient references, RSs were clinically administered for diarrhea, constipation, colitis, ascites, dysentery and intestinal parasites, sciatic, lower back pain and joint aches, fever, kidney disease and as an aphrodisiac. Objectives: The aim of this study is to categorize and review different types of RSs, their main herbal components and to find evidence to elucidate their clinical administration. Results: In this study, 7 manuscripts were studied to extract and categorize 11 types of herbal rectal suppositorie (RS) formulations, their ingredients and therapeutic indications. Furthermore, the Persian and scientific names of 43 herbs and their temperaments were mentioned in this study. Hence, ancient therapeutic indications of herbs used in RS formulations as well as their proven effects have been studied, which makes it possible to compare ancient and proven indications of medicinal plants used as ingredients of RSs. Conclusions: In modern medicine, RSs are mostly used for anorectic disorders. However in traditional Persian medicine, they were commonly used not only for anorectic and intestinal diseases, but also as an aphrodisiac, an agent for healing joint, sciatic pain and lumbago, an anti-fever, and an anti-ascites. Other implications of this study could be producing new insights of utilizing herbal RSs in diseases and disorders beyond anorectic and intestinal disorders.展开更多

Ethanol (EtOH) is sometimes applied to prevent local recurrence after curettage of benign bone tumors. However, the effects of PVI and EtOH on surrounding soft tissue and on bone union are unclear. The purpose of this study was to determine whether PVI or EtOH adversely affects the cancellous bone healing of the osteotomy site at the proximal tibia in rats. Methods: A cancellous bone osteotomy was performed at the right proximal tibia in 4-month-old, female, Sprague Dawley rats. Vehicle, 10% PVI, or 95% EtOH-soaked gauze was inserted into the osteotomy site and maintained for 6 minutes. The rats were euthanized 2 or 4 weeks after the osteotomy. Results: Two weeks after treatment, the bone union rate was significantly higher in the vehicle group than in the PVI group and the EtOH group (p < 0.001). However, the bone union rate was not significantly different between the PVI and EtOH groups. There was no significant difference among the three groups in the bone union rate 4 weeks after treatment. Conclusion: PVI or EtOH delayed bone union of the cancellous bone osteotomy site of the proximal tibia in the early phase (2 weeks), but not at 4 weeks, in rats.展开更多

The quantity of the antibiotic in the preparations studied was determined directly after they had been made and after a lapse of 7 and 14 days. We also carried out comparative examinations of the stability of sodium amoxicillin （Tarommentin） and sodium ampicillin （Ampicillin） in ointments with an addition of a boric acid solution. The examinations confirmed the stability of amoxicillin trihydrate in suppositories and in anhydrous and hydrated ointments. The content of this antibiotic in ointmems with an addition of a boric acid solution decreases slightly. Comparative studies of the stability of sodium amoxicillin and sodium amoxicillin revealed a markedly lower stability of the two antibiotics in comparison to the stability of amoxicillin trihydrate.展开更多

Taking into account that medicine is intended and prescribed for children, all the experiments were performed on immature nonlinear one-month rats with weight of 60.0-80.0 g. As a result, it was found out that rectal insertion of suppositories with an extract of licorice root causes an increase in the phagocytic function of neutrophils and increases the quantity of antibodies in the spleen and titers of hemagglutinins and hemolysins in serum, that indicating on the activation of nonspecific and humoral immunity of immature animals. Moreover, the prospects of possible application of suppositories with an extract of licorice root are showed for prevention and treatment of various immunodependent diseases, viral in particular.展开更多
