Frequency of Nonalcoholic fatty pancreatic disease in patients with carcinoma pancreas presenting for upper abdominal Endoscopic Ultrasound in a tertiary care center.

OBJECTIVE: To determine the frequency of nonalcoholic fatty pancreatic disease in patients with carcinoma pancreas presenting for upper abdominal endoscopic ultrasound. METHODS: The prospective cross-sectional study was conducted in the Endoscopy Suite of Surgical Unit 4, Civil Hospital, Karachi, from October 2019 to September 2020, and comprised patients presenting for endoscopic ultrasound. Patients were divided into Group A comprising carcinoma pancreas patients, and Group B having non-carcinoma pancreas patients. Fatty pancreas was identified by hyperechogenicity on endoscopic ultrasound. Data was analysed using SPSS 19. RESULTS: Of the 68 patients, 44(64.7%) were male and 24(35.3%) were females. The overall mean age was 49.9±13.82 years (range: 16-80 years). There were 35(51.5%) patients in Group A and 33(48.5%) in Group B. The frequency of nonalcoholic fatty pancreatic disease was 18(26.5%) and 15(83.3%) of them were male subjects (p=0.04). Group A had 12(34.28%) subjects with nonalcoholic fatty pancreatic disease compared to 6(18%) in Group B (p=0.11). CONCLUSIONS: Nonalcoholic fatty pancreatic disease was frequently seen in carcinoma pancreas patients undergoing endoscopic ultrasound compared to non-carcinoma pancreas patients. Most of the patients affected were males.

A comparative follow up study of transabdominal preperitoneal mesh repair in inguinal hernias with or without mesh fixation.

OBJECTIVE: To compare the recurrence rate and chronic pain in hernia patients undergoing laparoscopic or robotic transabdominal preperitoneal fixation with and without mesh. METHODS: The prospective comparative study was conducted at Surgical Units 4 and 5 of the Civil Hospital, Karachi, from August 1, 2017, to July 1, 2018, and comprised hernia patients undergoing laparoscopic or robotic transabdominal preperitoneal fixation who were randomised into fixation Group A and non-fixation Group B. Postoperative visual analogue scale score was calculated at the time of discharge. At 1-year follow-up, recurrence rate and chronic pain were assessed. Data was analysed using SPSS 23. RESULTS: Of the 98 patients, there were 49(50%) in each of the two groups. Of the total, there were 97(99%) males. The overall mean age was 44.52±14.51 years. The differences in visual analogue scale scores at the time of discharge and the mean discharge from the hospital in terms of days were statistically significant (p<0.005). At 1-year follow-up, there was recurrence in 1(1.02%) case and that was in Group A (p>0.05). Chronic pain between the groups was not significant (p>0.05). CONCLUSION: There was no significant difference in terms of recurrence and chronic pain between mesh and non-mesh fixation.

Resolution of symptoms after Heller's cardiomyotomy with DOR fundoplication versus endoscopic balloon dilatation in patients with achalasia Cardia at tertiary care hospital.

OBJECTIVE: To compare improvement in symptoms following Heller's myotomy with Dor fundoplication and endoscopic pneumatic dilatation for the treatment of achalasia cardia. METHODS: The prospective comparative study was conducted at the Department of Upper Gastroenterology and Minimally Invasive Surgery, Civil Hospital, Karachi, from February 2016 to January 2019, and comprised patients diagnosed with achalasia cardia on oesophageal manometry. The subjects were randomised into endoscopic pneumatic dilatation group A and laparoscopic Heller's myotomy with Dor fundoplication group B. Eckardt scores were compared between the groups at one-year follow-up. Data was analysed using SPSS 22. RESULTS: Of the 42 patients, 21(50%) were in each of the two groups. The mean age of patients in group A was 37±12.87 years compared to 34±8.59 years in group B. Treatment success in group A was 11(52%) compared to 21(76%) in group B. Eckardt scores between the groups were significant (p<0.001). Patient satisfaction was significantly more in group B (p<0.05). CONCLUSIONS: The efficacy of Heller's myotomy with Dor fundoplication was found to be greater than endoscopic pneumatic dilatation for improvement in dysphagia and overall patient satisfaction at one-year follow-up.

Does Fgf23-klotho activity influence vascular and soft tissue calcification through regulating mineral ion metabolism?

Recent studies describe a novel role of fibroblast growth factor-23 (Fgf23)-klotho activity in the systemic regulation of calcium and phosphate homeostasis. Both Fgf23 and klotho ablated mice develop extensive vascular and soft tissue calcification. Inability to clear the required amount of phosphate by the kidney, due to the absence of Fgf23-klotho activity, leads to increased accumulation of serum phosphate in these genetically modified mice, causing extensive calcification. Serum calcium and 1,25 hydroxyvitamin D levels are also elevated in both Fgf23 and klotho ablated mice. Moreover, increased sodium phosphate co-transporter activity in both Fgf23 and klotho ablated mice increases renal phosphate reabsorption which in turn can facilitate calcification. Collectively, these observations bring new insights into our understanding of the roles of the Fgf23-klotho axis in the development of vascular and soft tissue calcification.
