两种不同宫颈上药方法的效果研究

目的探讨一种简便、快捷、节约药粉的宫颈上药方法。方法在橡胶吸球底部剪一圆形切口,高压灭菌,把药粉装入吸球内,用医用胶布封住切口,用窥阴器暴露宫颈后,使吸球的尖嘴部对准宫颈创面,用手挤压吸球底部,使药粉喷洒在宫颈创面上。结果该宫颈上药方法与传统的宫颈上药方法相比,具有一次上药准确性高、上药所需时间短及节约药粉的优点。结论使用橡胶吸球进行宫颈上药的方法,无论是上药准确性、上药操作所需的时间及节约药粉方面,都明显优于传统的宫颈上药方法,值得在临床推广应用。     

Hemorrhoidal banding

Band ligation of symptomatic internal hemorrhoids is a well-established and accepted outpatient procedure. The purpose of this paper is to alert the medical profession to potential complications and death following this procedure. Each of the four patients described in this report experienced pain and inability to urinate following banding. This report does not condemn banding but, rather, focuses on problems associated with a procedure perceived by many to be risk free.

Short-Term and Long-Term Results of Combined Sclerotherapy and Rubber Band Ligation of Hemorrhoids and Mucosal Prolapse

PURPOSE: Rubber band ligation is a common office procedure for symptomatic hemorrhoids. The aim of the study was to assess our short-term and long-term results of combined sclerotherapy and rubber band ligation in the management of hemorrhoids and incomplete mucosal prolapse. METHODS: Data on 6,739 patients who had previous combined sclerotherapy and rubber band ligation by the senior authors (GLN and PRD) were retrieved from the database dating between January 1976 and June 2000. These patients either had hemorrhoids or incomplete mucosal prolapse. Furthermore, questionnaires were sent to a random sample of 2,400 patients. Telephone interviews were performed for 600 of the nonrespondents. RESULTS: Of 6,739 patients (3,683 males; mean age, 46.7 years) in the database, 4,686 (70 percent) received the procedure once, and 2,053 (30 percent) received the procedure more than once. There were 5,689 patients (84 percent) who had their procedures performed consecutively within a planned period, and only 1,050 patients (16 percent) had repeat procedures after a period of more than 12 months from their last treatments. Thus, the recurrence rate was 16 percent. The overall complication rate was 3.1 percent, with minor bleeding being the major complaint. With regard to the questionnaire, 44 percent responded. The mean follow-up period was 6.5 (range, 1–11) years. There were patients who had residual symptoms of bleeding (19 percent), itch (21 percent), and lump (20 percent). However, 58 percent of patients who replied were asymptomatic. With satisfaction scores ranging from +3 to –3 (+3 indicating complete satisfaction and –3 indicating complete dissatisfaction), 90 percent scored 1, 9 percent scored 0 or less, and 1 percent did not specify a score. Hemorrhoidectomy was required in 7.7 percent of the responders. Of 600 phone interviews with the nonrespondents, 152 responded to the questionnaires. Although there was less satisfaction from the phone respondents, which may have accounted for the initial nonresponse, no statistical difference was detected in residual symptoms. CONCLUSIONS: Combined triple sclerotherapy and rubber band ligation is an effective treatment for early hemorrhoids and incomplete mucosal prolapse, with low rates of recurrence, complications, and hemorrhoidectomy, and it can be repeated easily.     

Rubber band ligation of hemorrhoids: relapse as a function of time

Rubber band ligation is a well established treatment of internal second-degree hemorrhoids. Up to now, the long-term results (>5 years) of this method have not been assessed. The aim of this study was to determine the long-term success rate of rubber band ligation in patients with a first episode of second-degree hemorrhoids not responding to medical treatment (local cream with laxative). A total of 92 patients who were treated between 1979 and 1997 for second-degree hemorrhoids responded to a questionnaire. The need for complementary conservative (sclerotherapy, cryotherapy or rubber band ligation) or surgical treatment was considered indicative of relapse. The collected data were analyzed according to the Kaplan-Meier method. The average follow-up time was 5.6 years. There were 21 patients who suffered a relapse. The probability of successful treatment was 0.77 (range: 0.67–0.88) after 5 years and 0.68 (range: 0.5–0.86) after 10.6 years. We conclude that rubber band ligation represent an efficient long-term treatment for second-degree hemorrhoids. Approximately two thirds of the patients are cured after 5 years and more than a half after 10 years. Accepted: 5 June 1998

Body schema and body image—Pros and cons

There seems to be no dimension of bodily awareness that cannot be disrupted. To account for such variety, there is a growing consensus that there are at least two distinct types of body representation that can be impaired, the body schema and the body image. However, the definition of these notions is often unclear. The notion of body image has attracted most controversy because of its lack of unifying positive definition. The notion of body schema, onto which there seems to be a more widespread agreement, also covers a variety of sensorimotor representations. Here, I provide a conceptual analysis of the body schema contrasting it with the body image(s) as well as assess whether (i) the body schema can be specifically impaired, while other types of body representation are preserved; and (ii) the body schema obeys principles that are different from those that apply to other types of body representation.     

Accidental ingestion of foreign object: Systematic review,recommendations and report of a case

One of the serious complications during a routine endodontic procedure is accidental ingestion/aspiration of the endodontic instruments, which can happen when proper isolation is not done. There are at present no clear guidelines whether foreign body ingestion in the gastrointestinal tract should be managed conservatively, endoscopically or surgically. A 5 year old boy reported to the Department of Pediatric and Preventive Dentistry, D.A. Pandu Memorial R.V. Dental College, Bangalore, India, with a complaint of pain and swelling in the lower right back teeth region. Endodontic therapy was planned for the affected tooth. During the course of treatment the child accidentally swallowed a 21 mm 15 size K file. Endoscopy was performed immediately but the instrument could not be retrieved. The instrument passed out uneventfully along with the stools 48 h after ingestion.Careful evaluation of the patient immediately after the accident helps in managing the patient effectively along with following the recommended guidelines.
