Role of Vitamin B12 Deficiency and Hyperhomocysteinemia in Diabetic Retinopathy.

Diabetic retinopathy (DR) is one of the most important causes of preventable visual impairment among patients of working age and leading cause of blindness. Deficiency of vitamin B12 and folate has been associated with increased serum homocysteine (Hcy) levels. This study was done to find out the role of vitamin B12 and Hyperhomocysteine (HHcy) in Diabetic retinopathy. The present study is a hospital-based case-control study conducted during over a period of 12 months from January 2019 to December 2019 study conducted in the Department of Ophthalmology at BIRDEM General Hospital, Dhaka, Bangladesh consisting of 100 Type 2 DM patients either with or without retinopathy (DR, n=50 and DNR, n=50, respectively). Subjects with Type 2 DM with and without retinopathy were recruited from patients attending in the department of Ophthalmology at BIRDEM General Hospital, Dhaka and were matched for duration of diabetes. Diabetes subjects on nutritional supplements for the last 6 months and those with a history of nephropathy (based standard renal function tests) and complications other than DR were excluded. Homocysteine (Hcy) levels were inversely related (p<0.05) with Diabetes patients with retinopathy. Vitamin B12 also significant correlated with Diabetes patients with retinopathy. A statistically significant negative linear relationship was found between serum homocysteine and vitamin B12 levels (Pearson r = -0.918, p=0.001) Diabetes patients with retinopathy. Vitamin B12 significantly correlated with diabetes retinopathy and homocysteine levels were inversely related with diabetes patients with retinopathy.

Results of Laparoscopic Cholecystectomy in Acute Cholecystitis in Diabetic Patients: A Study with 50 Cases.

Acute cholecystitis (AC) is a common surgical condition requiring emergency hospitalization. Diabetic patient with gall stones disease is more prone to develop acute cholecystitis and its complications e.g. mucocele, empyema, gangrene and perforation. Early laparoscopic cholecystectomy (ELC) has proved to be an effective and safe day case surgical procedure for AC and their complications. This cross sectional study of diabetic patients admitted with acute cholecystitis, at the Department of Surgery of Bangladesh Institute of Researcher of Rehabilitation in Diabetes, Endocrine and Metabolic Disorder (BIRDEM) General Hospital, Dhaka, Bangladesh from March 2016 to January 2017. A total number of 50 patients of known diabetes of acute cholecystitis were recruited irrespective of their age and sex and by excluding pregnant woman, obstructed jaundice and severe cardiopulmonary disease. More than half (52.0%) of the cholecystitis patients belonged to 31-40 years with mean age was 52.5±12.1 years. Females were predominant in this study (68.0%) with male: female ratio was 1:2.1. All (100%) patents had pain in right hypochondrium but relatively lower than non-diabetic patient due to diabetic neuropathy followed by majority 74.0% had nausea/vomiting, 70.0% had history of flatulence and dyspepsia, 62.0% had Murphy's sign positive. Thirty (60.0%) patients had glycaemic control and 20(40.0%) had uncontrolled DM. Insulin received patients were 35(70.0%) and 15 took oral hypoglycemic drug. Regarding postoperative complication, 8.0% had severe vomiting, right hypochondriac pain, 4.0% had wound sepsis and 2.0% had decreased pulmonary function and mild chest infection. In this study among laparoscopic finding during operation age and sex were not statistically significant. There was no mortality; laparoscopic cholecystectomy is the safe, accepted and preferred method of treatment for acute cholecystitis.

The histopathology of congenital pouch colon associated with anorectal agenesis.

The colonic pouch excised during surgery in 17 patients with congenital pouch colon associated with anorectal agenesis (CPC) was subjected to detailed histological examination after staining with hematoxylin and eosin. The patients included 11 newborns, 3 infants, and 3 older children. The most frequently observed abnormalities were acute and chronic inflammation of the mucosa and submucosa, focal or generalized thinning of muscle layers, especially of the outer muscle coat, disorganized muscle layers, a decreased number of mature ganglion cells, and neuronal hyperplasia and hypertrophy in nerve plexuses. Ectopic heteroplastic tissues were identified in 2 patients. These findings suggest that the colonic pouch in CPC represents abnormally developed colonic tissue and points to the similarity with segmental dilatation of the colon. The neuromuscular abnormalities explain the physiological characteristics of the colonic pouch, namely weak peristalsis as well as the propensity to undergo marked dilatation even after tubularization.

Malignant fibrous histiocytoma of peritoneum presenting as intestinal obstruction.

Malignant fibrous histiocytoma (MFH) is a high-grade soft-tissue sarcoma of fibroblast-cell origin with a propensity for metastasis and recurrence. Primary MFH of the peritoneum is rare. We report a 60-year-old man with MFH of the peritoneum presenting with obstructive symptoms. Complete surgical excision of the tumor was done, and he is well six months later.
