Despite the increasing number of patients with the human immunodeficiency virus (HIV) infection. surgical experience with these patients remains limited. A retrospective review over a 9 year period (January 1985 to December 1993) was undertaken to determine the indications, operative management. pathologic findings and outcome of major abdominal surgery in these patients. A total of 51 procedures were performed in 45 patients; 30 patients had acquired immunodeficiency syndrome (AIDS) and IS patients had asymptomatic HIV infection. Indications included gastrointestinal bleeding. complicated pancreatic pseudocysts. cholelithiasis. bowel obstruction, immune disorders, acute abdomens. elective laparotomy. colostomy formation. menorrhagia and Caesarean section. Pathologic findings directly related to the HIV infection were found in 81% of the AIDS patients and 35% of the asymptomatic HIV infected patients (P<0.05). These included opportunistic infections. non‐Hodgkin's lymphoma. Kaposi's sarcoma, immune disorders. lymphadenopathy and pancreatic pseudocysts. It was noted that AIDS patients had more complications than asymptomatic HIV infected patients with most complications related to chest problems and sepsis (61 vs 7%; P<0.01). Emergency operations carried a higher complication rate than elective operations though this was not significant. The hospital mortality was 12%. On follow up, 13 of the 25 AIDS patients had died with the median survival of 7 months, while three of the 14 asymptomatic HIV infected patients had died with the median survival of 40 months. Of the remaining patients, the 12 AIDS patients had a median postoperative follow up of 7 months and the 11 asymptomatic HIV infected patients had a median postoperative follow up of 29.5 months. Despite impaired immune function, surgical treatment of HIV infected patients with abdominal pathology can be practised with acceptable mortality and morbidity and be of major benefit to these patients.
The POSSUM scoring system with the modified P-POSSUM predictor equation for mortality was applicable in Malaysia, a developing country, for risk-adjusted surgical audit. This scoring system may serve as a useful comparative audit tool for surgical practice in many geographical locations.
Diabetic foot ulcers present across the spectrum of nonhealing wounds, be it acute or many months duration. There is developing literature highlighting that despite this group having high caloric intake, they often lack the micronutrients essential for wound healing. This study reports a retrospective cohort of patients’ micro- and macro-nutritional state and its relationship to amputation. A retrospective cohort was observed over a 2-month period at one of Australia’s largest tertiary referral centers for diabetic foot infection and vascular surgery. Patient information, duration of ulcer, various biochemical markers of nutrition and infection, and whether the patient required amputation were collected from scanned medical records. A cohort of 48 patients with a broad-spectrum of biochemical markers was established. Average hemoglobin A1c (HbA1c) was 8.6%. A total of 58.7% had vitamin C deficiency, including 30.4% with severe deficiency, average 22.6 Ł} 5.8 μmol/L; 61.5% had hypoalbuminemia, average albumin 28.7 Ł} 2.5 g/L. Average vitamin B12 was 294.6 Ł} 69.6 pmol/L; 57.9% had low vitamin D, average 46.3 Ł} 8.3 nmol/L. Basic screening scores for caloric intake failed to suggest this biochemical depletion. There was a 52.1% amputation rate; biochemical depletion was associated with risk of amputation with vitamin C ( P < .01), albumin ( P = .03), and hemoglobin ( P = .01), markedly lower in patients managed with amputation than those managed conservatively. There was no relation between duration of ulceration and nutrient depletion. Patients with diabetic foot ulceration rely on multidisciplinary care to optimize their wound healing. An important but often overlooked aspect of this is nutritional state, with micronutrients being very important for the healing of complex wounds. General nutritional screening often fails to identify patients at risk of micronutrient deficiency. There is a high prevalence of vitamin deficiency in patients with diabetic foot ulcers. This presents an excellent avenue for future research to assess if aggressive nutrient replacement can improve outcomes in this cohort of patients.
This study shows that AAA in this Asian population is not uncommon and the incidence is comparable to the Western world.
Historically, Streptococcus pyogenes was a common cause of endocarditis and infected aortic aneurysm. Today, endovascular infections due to this organism have become exceedingly rare. We report the first case of aortic aneurysm infection due to S. pyogenes treated with initial endoluminal repair, review previous reports and discuss current treatment options.
Plasmaphoeresis may be risk factor for Nocardia infection and need further study. Nocardia infection may coexist with other opportunistic infections. Identification of the Nocardia species and drug susceptibility testing is essential in guiding the effective management of patients with Nocardia. Intermittent TMP-SMX (one double strength tablet, twice a week) appears insufficient to prevent Nocardia infection in renal transplant recipients.
PE drainage is a safe and viable method for pancreas transplantation, which can be performed with excellent outcomes. An increased rate of complications with PE drainage has not been demonstrated in this series.
Background: A consecutive series of 269 cases of bleeding gastric ulcer were studied prospectively from 1979 to 1993 inclusive. Method: Fifty‐five (21%) had a giant gastric ulcer with a diameter of 3 cm or more. These cases were compared with those with ulcers less than 3 cm in diameter in terms of clinical details, prognostic factors, urgent operation and outcome. Results: Death occurred in 13 cases (5%), urgent surgery was performed in 75 cases (29%) and there were 11 postoperative deaths (15%) within a month of surgery. The patient details in the two groups matched in terms of age, sex distribution, ulcer history, previous complication and recent ingestion of analgesics. Clinical comparison showed that giant ulcer had a poorer prognosis with a higher mortality (10 vs 3%, P < 0.01), urgent surgery rate (65 vs 12%, P < 0.01) and operative mortality (23 vs 11%, difference not significant). Study of risk factors in patients with giant ulcer revealed significantly more with concurrent illness, shock, anaemia and endoscopic stigmata of recent haemorrhage. Conclusion: More severe bleeding and poorer general condition in the giant ulcer group stresses the importance of early diagnosis and accurate resuscitation in these patients. Survival depends on optimal condition and prompt and timely surgery.
