RESUMO
Background: Colonoscopy is widely used as a tool for diagnosis, screening and treatment of various pathologies in the rectum, colon, and terminal ileum. The aim of this study is to evaluate the demographic, clinical, and histological parameters of the records of patients undergoing colonoscopy at a tertiary care hospital in Nepal. Materials and methods: This retrospective cross-sectional study included the hospital records of all patients who underwent colonoscopy from 2015 to 2019 in a tertiary care centre in Nepal. Results: A total of 1255 records were included in the study. The mean and standard deviation of age were 43.8 and 19 years, respectively. Among the total study population, 61.9% were males and 38.1% were females. Common indications for colonoscopy included lower gastrointestinal bleeding (27.7%), altered bowel habit (26.9%) and persistent or recurrent abdominal pain (17.3%). Only 3% of the patients who underwent colonoscopy had inadequate bowel preparation. The overall diagnostic yield of colonoscopy was 57.5%. Findings during colonoscopy included colorectal polyp (19.4%), internal haemorrhoids (8.2%) and colitis (6.5%). Having an age of 50 or more years was significantly associated with the presence of colorectal adenocarcinoma (P=0.017, χ2 test) with an odds ratio of 2.35 (95% CI: 1.14, 4.89). Furthermore, having a female sex was found to be significantly associated with the presence of colorectal adenocarcinoma (P=0.012, χ2 test) with an odds ratio of 2.43 (95% CI: 1.19, 4.97). Conclusion: In the authors' study, a smaller proportion of the colonoscopies was aimed at screening for colorectal carcinoma (CRC), when compared to studies in developed countries. The sex predisposition of CRC in the authors' study is in contrast to the global trend. The authors recommend conducting studies to determine the risk factors and need for CRC screening in the Nepalese population.
RESUMO
Introduction and importance: Lambda-cyhalothrin is a type II pyrethroid compound commonly used as a pesticide, with the potential to cause life-threatening toxicity in humans. Furthermore, among cases of pesticide poisoning in Nepal, organophosphates are most frequently implicated. Case presentation: A 40-year-old female presented to our hospital after ingesting a pesticide compound with suicidal intent. She also admitted to alcohol intoxication and exhibited symptoms of confusion, abdominal pain, nausea, and vomiting. An atropine challenge test yielded negative results. Therefore, conservative management was continued. It was discovered later that the ingested pesticide was lambda-cyhalothrin. The patient's condition eventually improved with supportive treatment. Clinical discussion: Several reports have highlighted the overlapping clinical features between organophosphorus and pyrethroid poisoning. In some cases of pyrethroid poisoning, misdiagnosis as organophosphorus poisoning has occurred, leading to the inappropriate administration of atropine. In our case, initial management was challenging owing to the lack of accurate information about the ingested compound. On further evaluation, cholinergic clinical features were absent and the atropine challenge test was negative. This was suggestive of nonorganophosphorus compound poisoning. Conclusion: This case illustrates that managing pesticide poisoning becomes challenging when the nature of the pesticide is unknown. Patients suffering from poisoning caused by pyrethroid compounds like lambda-cyhalothrin can present with features resembling organophosphorus poisoning. In such circumstances, a comprehensive clinical evaluation should guide the management. Clinical features and an atropine challenge test can aid in differentiating organophosphorus from nonorganophosphorus compound poisoning. This distinction facilitates therapeutic decision-making, including the consideration of atropine administration.
RESUMO
INTRODUCTION AND IMPORTANCE: Takayasu's Arteritis (TA) is a rare form of large vessel vasculitis often being apparent late in its progression with features of artery occlusion. Studies comparing endovascular approach with bypass surgeries reveal surgery to be a better option with lesser rates of postoperative restenosis. CLINICAL PRESENTATION: A 25-year-old female patient presented with dizziness, headache, claudication and paresthesias in the right arm. Her right radial pulse couldn't be appreciated and BP on the right brachial artery was unrecordable. BP on her left brachial artery was 160/110 mmHg. CT angiogram demonstrated stenosis in the right subclavian, coeliac and left renal artery. After adequate control of hypertension and ruling out the active phase of TA, she underwent right carotid to subclavian bypass with Polytetrafluoroethylene(PTFE) graft. At 1 year follow up there was significant improvement in her right arm claudication. DISCUSSION: Symptomatic cases of TA need either endovascular angioplasty or surgical intervention to establish reperfusion. Surgery must be done only in the inactive phase of the disease because of the risk of reocclusion. The remission of TA is difficult to predict with clinical findings and ESR values. Oftentimes biopsies taken from the arteries of patients who underwent surgery showed features of active inflammation. CONCLUSION: We recommend all cases of TA to be treated with a course of steroids before planning for surgery irrespective of symptomatology and ESR values. Bypass surgeries with PTFE graft along with preoperative or postoperative steroid therapy result in resolution of ischemic symptoms.
RESUMO
Empyema thoracis is a condition characterized by the accumulation of pus in the pleural cavity of the lungs. Empyema thoracis is a cause of high mortality in man and its occurrence is increasing in both children and adults. Traditionally, chest tube drainage has been a preferred method of treatment, but recent studies have shown that pigtail catheter drainage is a more effective and less invasive alternative. Image-guided drainage is also preferred over blind drainage, and alternative drainage sites are being explored. These management changes have improved patient outcomes and reduced the risk of complications. Case presentation and clinical discussion: A 66-year-old female presented with complaints of cough, fever, and chest pain. A clinical examination was done and relevant investigations were sent. She was then treated in the line of left-sided empyema thoracis. A pigtail catheter was inserted into the loculated empyema via the left 9th intercostal space through a posterolateral approach with ultrasonography guidance. Conclusion: The main aim of this article is to provide an overview of a rare management approach for empyema, a condition characterized by the accumulation of pus in the pleural cavity of the lungs. In this case report, the authors have focused on pigtail catheter drainage over traditionally performed chest tube drainage, and image-guided drainage has been performed over blind drainage ensuring accurate placement and reducing the risk of damage to surrounding tissues. Another notable change in empyema management is the shift in drainage sites from the safety triangle to other sites based on the site of loculations under ultrasonography guidance.
RESUMO
Ewing sarcoma (ES) is a malignant tumour prevalent in young adults with a reported 5-year survival ranging between 40 and 60% in most studies. Majority of the patients with ES are usually diagnosed late with significant chest wall mass, chest pain or respiratory distress. Case presentation: Here, the authors present a case of a 21-year-old female with a diagnosis of right sided chest wall ES treated with neoadjuvant chemotherapy followed by surgical resection of the mass. Clinical findings and investigations: The patient presented to the Surgical OPD with shortness of breath for 6 months associated with chest pain on the right side. Radiological investigations including chest X-ray and multi-detector row computed tomography chest was done. Additionally, diagnosis of ES was confirmed with histopathological examination of the mass obtained from fine needle aspiration cytology. Interventions and outcome: She was planned for safe maximal resection of tumour with chest wall reconstruction using double prolene mesh with bone cement and the defect was sutured with adjacent ribs. Good outcome was noted on postoperative period with resolution of symptoms. Relevance and impact: This procedure is now commonly used and is considered as an effective treatment for chest wall tumours, which was also noted in our case and the procedure is also well tolerated.
RESUMO
INTRODUCTION AND IMPORTANCE: Klippel-Trenaunay syndrome (KTS) is characterized by a triad of port-wine stain, varicose veins and soft tissue or bony hypertrophy of lower limb. Varicose veins in Klippel Trenaunay syndrome are mostly distributed in the lateral aspect of the lower limb. The exact etiology of KTS is not known, and the treatment usually starts with conservative management- limb elevation, compression stockings and physiotherapy. However, some cases are severe enough to warrant surgical management. CASE PRESENTATION: Here we present a case of a 3-year-old male child with clinical features suggestive of Klippel Trenaunay Syndrome managed successfully with sclerotherapy of persistent lateral marginal vein of servelle. At one month follow-up the vein was sclerosed and there was a significant reduction in varicosities of leg. CLINICAL DISCUSSION: Starting treatment of varicose veins in Klippel Trenaunay Syndrome in children is effective in preventing long-term complications in adults. Thus, treating venous malformation with sclerotherapy is warranted in early childhood to prevent venous hypertension and chronic venous insufficiency. CONCLUSION: Varicose veins in KT syndrome can be managed successfully by sclerotherapy of lateral marginal vein of servelle resulting in significant reduction in varicosities of leg.
