Neurologic eye signs following motorcycle accidents

A review of 96 consecutive patients who suffered neuro-ophthalmologic injuries in motorcycle accidents revealed a wide range of findings. These findings were similar to signs associated with other forms of closed-head trauma, aside from a higher incidence of trochlear nerve palsies.     

Toxic epidermal necrolysis; 15 years'' experience in a Dutch burns centre

BACKGROUND: Toxic epidermal necrolysis (TEN) is a severe and potentially fatal drug reaction characterized by an extensive skin rash with blisters and exfoliation, frequently accompanied by mucositis. The wounds caused by TEN are similar to second-degree burns and severe cases may involve large areas of skin loss. OBJECTIVES: Analysis of our results in patients with TEN and evaluation of the variety of therapeutic interventions that has been studied and suggested in TEN. PATIENTS/METHODS: Retrospective analysis of 19 consecutive patients with TEN treated in our burns centre between 1989 and 2004. RESULTS: Immediate withdrawal of any potentially fatal drug, maximum supportive care, and a restricted and tailored antibiotic, medical and surgical treatment regimen confined mortality to 21%, whereas prognosis scores like APACHE II and SCORTEN predicted mortality of 22 and 30%, respectively. A positive contribution of selective digestive decontamination is suggested but has yet to be established. CONCLUSIONS: Because of a potentially fatal outcome, fast referral of a patient suspected of TEN to a specialized centre (mostly a burns unit or specialized dermatology centre) for expert wound management and tailored comprehensive care is strongly advised and contributes to survival.     

女性慢性下腹痛的干预性治疗

1背景 育龄妇女常见慢性下腹痛，可造成身体损害、情绪忧伤及导致巨大的健康服务费用。美国在这方面的花费超过8亿8千万美元（Mathias 1996）。英国全国数据库的一般性诊治资料显示，慢性下腹痛发病率及流行率与偏头痛、背部痛、哮喘发病率相似（Zondervan 1999）。     

Surgical treatment of urinary stress incontinence.

This article reviews traditional vaginal and suprapubic procedures as well as more recent advances such as urethral bulking agents and artificial sphincters. It illustrates how the chosen operation must be tailored to the individual patient and how the surgeon treating urinary incontinence requires a variety of procedures in his repertoire.     

Effect of growth hormone on human alveolar macrophage oxidative metabolism

BACKGROUND: Growth hormone (GH) has diverse immunological actions and has been shown to augment oxidative metabolism in rat peritoneal and porcine alveolar macrophages and both human and animal neutrophils. A study was performed to determine the effects of GH on human alveolar macrophages in vitro. METHODS: Macrophages were harvested from 10 patients undergoing bronchoalveolar lavage and incubated with 0, 10 and 100 nmol/ml GH for four hours. Oxidative metabolism was assessed by means of a fluorescent assay using FMLP and E coli as stimulants. Fluorescence was measured using flow cytometry. RESULTS: No difference in basal or stimulated oxidative metabolism was found between the GH and control groups. CONCLUSIONS: GH does not have a direct stimulatory action on human alveolar macrophages in vitro. However, this does not exclude an indirect effect in vivo. The results contrast with previous studies on animal alveolar macrophages.




     

The microbial flora of in-use blood pressure cuffs

The capacity of blood pressure cuffs to act as vehicles of hospital infection has been recognised. We describe the microbial flora of in-use DINAMAP blood pressure cuffs used in the operating theatres and one recovery room in a teaching hospital. Our results show significant microbial contamination of in-use blood pressure cuffs.     

Percutaneous balloon pericardiotomy in the management of recurrent malignant pericardial effusions

Two patients with recurrent symptomatic pericardial effusions secondary to malignant disease were successfully treated by percutaneous balloon pericardiotomy. Open surgery was avoided and the procedure was completed under local anaesthesia in less than 40 minutes. The first patient was free of recurrence at nine months but pericardial effusion recurred at two months in the second patient.Percutaneous balloon pericardiotomy offers a potentially important new means of relieving recurrent tamponade and substantially reduces trauma to the patient.     

Prevalence of asymptomatic bacteriuria in subjects with NIDDM in San Luis Valley of Colorado

This study examined whether non-insulin-dependent diabetic (NIDDM) subjects have an increased prevalence of asymptomatic bacteriuria compared with subjects with normal glucose tolerance. Diabetic (n = 206) and normal (n = 418) subjects were identified from a defined geographic area in the San Luis Valley of southern Colorado. Presence of asymptomatic bacteriuria was determined by testing the subjects' urine with a reagent-strip test for nitrite and leukocyte esterase (Chemstrip LN). The ability of the Chemstrip LN to detect bacteriuria was evaluated by comparing its results with those from urine culture on a subsample of subjects. There were 7 control and 12 diabetic subjects with bacteriuria as measured by the Chemstrip LN. The prevalence of urinary tract colonization among diabetic compared with control subjects was increased 3.5-fold (95% confidence interval 1.4-8.6). Adjustment for confounding by age, sex, ethnicity, and county of residence resulted in an adjusted prevalence ratio of 4.4 (95% confidence interval 1.1-17.4). Among diabetic subjects, prevalence of bacteriuria increased with longer disease duration but was not affected by measures of glucose control. We conclude that NIDDM increases the prevalence of bacterial colonization of the urine and, therefore, probably also increases the risk of symptomatic urinary tract infection.
