Dobutamine stress echocardiography in preoperative and long-term postoperative risk assessment of elderly patients

The authors reviewed all negative preoperative dobutamine stress echocardiograms (DSEs) performed over a 3-year period to determine the value of negative DSE for preoperative risk assessment in elderly patients. All patients with negative DSE performed for preoperative evaluation were followed. Cardiac event rates during and after the operative procedure were determined for hard end points (nonfatal myocardial infarction, cardiac death) and soft end points (emergency room visits, hospitalization for unstable angina, congestive heart failure, coronary angioplasty, coronary artery bypass graft surgery). Results noted that DSEs were negative for ischemia in 82 preoperative evaluations. Group 1 (age=65; n=41) had hard and soft event rates per patient/year of 0.97% and 7.3%, while group 2 (age <65; n=41) had hard and soft event rates per patient/year of 0.81% and 10.8%. There were no significant differences in event rates between the two groups (p=NS). In conclusion, the authors found that negative DSEs predict low cardiac event rates in elderly patients during the perioperative and long-term postoperative periods, which are not significantly different from the cardiac event rates in a younger cohort.     

Provision of antiretroviral treatment in conflict settings: the experience of Médecins Sans Frontières

Introduction  

Many countries ravaged by conflict have substantial morbidity and mortality attributed to HIV/AIDS yet HIV treatment is uncommonly available. Universal access to HIV care cannot be achieved unless the needs of populations in conflict-affected areas are addressed.     

Ruptured staphylococcal splenic abscess resulting in peritonitis: report of a case

A 50-year-old man presented with features of peritonitis of 2 days duration. The signs were more marked in the left upper abdomen. Investigations followed by a laparotomy showed a ruptured splenic abscess, the cause of which was not apparent. We herein present the case report of this unusual cause of peritonitis along with a relevant review of the literature. Received: June 22, 2001 / Accepted: November 20, 2001     

A study of the health of Malaysian plantation workers with particular reference to paraquat spraymen.

Tests of pulmonary function (FVC, FEV1, FEV 1%, and single breath CO diffusion), renal function (serum creatinine and BUN), liver function (serum ALT, AST, and ALKP) and a full haematological screen were performed on 27 paraquat spraymen (mean spraying time 5.3 years; mean individual annual quantity of paraquat handled, 67.2 kg as paraquat ion) and on two control groups. One of the control groups consisted of 24 general plantation workers with minimal exposure to paraquat arising from occasional work in recently sprayed areas, and the second consisted of 23 latex factory workers with no known occupational exposure to paraquat. The results showed no significant differences as a consequence of occupational exposure to paraquat. Long-term paraquat spraying at the concentrations used produced to quantifiable harmful effects on health as measured by the indices selected for this study.     

Parachute Method: A Novel Method to Retrieve a Stuck Degloved Finger

An entrapped finger is a relatively uncommon domestic injury. When the finger gets stuck proximal to the proximal interphalangeal joint, the resultant distal edema and inappropriate attempts at retrieval can result in circumferential degloving of the skin and injury to the neurovascular structures. We report a technique that can be used in such circumstances. Strategically placed skin sutures are used to get the skin through the constricting ring, and retrieval is aided by a cut finger glove that wraps the finger and can be lubricated. This non-cutting technique is named as the parachute technique since the withdrawn skin sutures look like the strings of the parachute. This technique is valuable when the finger gets stuck in an idli plate, a common South Indian kitchen utensil, where there is difficulty of access to cutting equipment and where inappropriate attempts at retrieval can result in skin injury making further attempts more difficult.     

Awareness of breast cancer and screening procedures among Malaysian women

Breast cancer is the most frequently occurring cancer in women globally and early detection increases the survival rate of patients. Therefore, this study was done to determine factors which influence the awareness of breast cancer and practice of screening procedures. A cross-sectional study was performed on 125 women aged 19-60 years in urban and rural areas in Malaysia using a validated questionnaire covering knowledge of breast cancer and screening practices. A total of 99.2% respondents knew that breast cancer is the leading cancer with a mean knowledge of 67.3 ± 15.3% for urban and 50.2 ± 14.7% for rural women Mann Whitney U showed rural women had significantly less awareness compared to urban women (p< 0.05). Spearman correlation test showed a significant positive relationship between education and awareness (p< 0.05). Regarding awareness of the screening methods, 92.8%, 50.4% and 47.2% of respondents correctly answered questions on capability of BSE, CBE and mammography, respectively. In conclusion, the study showed awareness of breast cancer and practice of screening procedures increases with higher education and urban living. Therefore, there is an urgent need for an intensive breast cancer awareness campaign and availablity of screening centres prioritized in rural areas.     

Assessment of the hand in cerebral palsy

Cerebral palsy is the musculoskeletal manifestation of a nonprogressive central nervous system lesion that usually occurs due to a perinatal insult to the brain. Though the cerebral insult is static the musculoskeletal pathology is progressive. Some patients with cerebral palsy whose hands are affected can be made better by surgery. The surgical procedures as such are not very technically demanding but the assessment, decision-making, and selecting the procedures for the given patient make this field challenging. When done well, the results are rewarding not only in terms of improvement in hand function but also in appearance and personal hygiene, which leads to better self-image and permits better acceptance in the society. This article focuses on the clinical examination, patient selection, and decision-making while managing these patients.KEY WORDS: Assessment, cerebral palsy, decision-making, examination, spastic hand     

The relation of patient satisfaction and functional and cosmetic outcome after correction of the wrist flexion deformity in cerebral palsy

Wrist flexion deformity in cerebral palsy is treated with flexor carpi ulnaris to extensor carpi radialis brevis transfer. The aim of the study was to assess the outcome of this procedure and analyse the determining factors for patient satisfaction. Fifteen patients were reviewed after a mean follow-up of 23 months. The functional and cosmetic outcome and patient satisfaction were evaluated using patient rated scales. There was a strong and significant correlation between the cosmetic outcome and patient satisfaction, but there was no significant correlation between functional improvement and patient satisfaction. When analysing the cosmetic outcome in relation to the time since surgery, there was a decrease in the patient rated improvement over time. It seems that patient satisfaction is mainly determined by the cosmetic result, but the improvement, or the perception of it, tends to diminish over time. Fourteen out of 15 patients felt that the procedure was worthwhile and eight of them felt that the result was good or excellent.
