Severe steroid-unresponsive ulcerative colitis

PURPOSE: The recent introduction of the immune suppressor cyclosporin for treatment of steroid-refractory ulcerative colitis has required surgeons to perform a colectomy in those patients who eventually fail this rescue treatment, thus raising questions as to the safety of surgery as performed in patients with a heavily manipulated immune system. To assess the rates of mortality and morbidity in this setting, we studied a cohort of consecutive patients who had surgery after failing cyclosporin for refractory ulcerative colitis at our center. METHODS: Between January 1991 and December 1996, 25 patients with ulcerative colitis underwent restorative proctocolectomy performed in three steps (21 patients) and in two steps (4 patients). Seventeen of the 25 patients (68 percent) were initial nonresponders to a dose of 2 mg/kg/day of intravenous cyclosporin and underwent surgery immediately, the remaining 8 (32 percent) relapsed as outpatients on oral cyclosporin and were readmitted for surgery. RESULTS: There was no operative mortality. Nine patients of the 25 developed postoperative (early) complications (36 percent). The three-step operation subset had a 28 percent complication rate, the two-step 75 percent. Three patients needed reoperation. A total of 11 patients (44 percent) reported with late complications: two patients required surgical treatment, one for obstruction and one for pouch-perianal fistula. Three cases of pouchitis were recorded. No patient required pouch removal. CONCLUSION: Given the absence of postoperative mortality and a low overall complication rate, restorative proctocolectomy can safely be perofrmed in patients who fail rescue treatment with a dose of 2 mg/kg of cyclosporin for steroid-refractory ulcerative colitis. Corollary evidence in this article hints but does not prove that the three-step procedure is safer than the two-step operation.     

Left atrial approach to big myxoma with angiographically visible neovascularity. Report of one case.

In this article, we report a 65-year-old man with a large atrial myxoma arising from the posterior wall and from the base of the right inferior pulmonary vein. The big neoplastic mass showed a large implant site. A rare atrial myxoma neovascularity arising from the atrial circumflex artery was very clearly visualized by selective coronary arteriography. The surgical approach used to resect this tumor was an isolated left atriotomy that provided excellent exposure and safe excision.

Prevalence of depressive symptoms and its associated factors in older adults: a cross-sectional study in Kathmandu,Nepal

Objective: Globally, depression is one of the most prevalent and burdensome conditions in older adults. However, there are few population-based studies of depression in older adults in developing countries. In this paper, we examine the prevalence of depressive symptoms and explore possible contributory risk factors in older adults living in Nepal.

Methods: A cross-sectional study was conducted in two semi-urban communities in Kathmandu, Nepal. Depression was assessed using the 15-item Geriatric Depression Scale in 303 participants, aged 60 years and over. Multivariate logistic regression was then used to assess associations between potential risk factors and depression.

Results: More than half of the participants (n = 175, 60.6%) had significant depressive symptomatology, with 27.7% having scores suggesting mild depression. Illiteracy (aOR = 2.01, 95% CI: 1.08–3.75), physical immobility (aOR = 5.62, 95% CI: 1.76–17.99), the presence of physical health problems (aOR = 1.97, 95% CI: 1.03–3.77), not having any time spent with family members (aOR = 3.55, 95% CI: 1.29–9.76) and not being considered in family decision-making (aOR = 4.02, 95% CI: 2.01–8.04) were significantly associated with depression in older adults.

Conclusion: The prevalence of depression was significant in older adults. There are clear associations of depression with demographic, social support and physical well-being factors in this population. Strategies that increase awareness in the community along with the health and social care interventions are needed to address the likely drivers of depression in older adults.     

Bizarre and scary ECG in yew leaves poisoning: Report of successful treatment

Yew leaves poisoning is a rare life‐threatening intoxication, whose diagnosis can be difficult. Initial symptoms are nausea, vomiting, abdominal pain, dizziness, tachycardia, muscle weakness, confusion, beginning within 1 hr from ingestion and followed by bradycardia, ventricular arrhythmias, ventricular fibrillation, severe hypotension, and death. Taxine‐derived alkaloids are responsible for the toxicity of the yew leaves, blocking sodium and calcium channels, and causing conduction abnormalities. Because of lack of a specific antidote and limited efficacy of common antiarrhythmic drugs, prompt diagnosis, detoxification measures, and immediate hemodynamic support (also with transvenous cardiac stimulation) are essential.
