Effectiveness of Topical Insulin Dressings in Management of Diabetic Foot Ulcers.

BACKGROUND: Infected diabetic foot ulcers are always a problem for the surgeon, as well as, an economic burden upon the patient and state, in terms of increased hospital stay and cost of medications and dressings. Various methods have been devised for the treatment of infected wounds in history with varying results in different patients groups. The purpose of this study is to compare the effectiveness of topical insulin on the healing of diabetic foot ulcers with the conventional Pyodine® povidone iodine dressing. Our objective was to compare effectiveness of topical insulin with conventional Pyodine® povidone iodine dressings in frequency of healing of diabetic foot ulcers. MATERIALS AND METHODS: It was a quasi-experimental study done at Pakistan Institute of Medical Sciences Islamabad over a period of 20 months from January 2015 to September 2016. One hundred ten patients were included in the study. Sampling technique used was non-probability consecutive. Patients were assigned into two groups, group A receiving treatment with solution of 30 International Units Insulin Regular in 30 ml of normal saline and group B receiving conventional dressing with normal saline. The wound were compared for both groups at the days 7, 14 and 21 for wound healing. Complete healing time of diabetic foot ulcers was determined from patients' followup visits in outpatient department. Data was by analyzed by SPSS 20. RESULTS: A total of 110 patients were enrolled in the study. Patients were divided equally into both control and experimental groups. The mean age of the patients was 53.23 ± 6.21 years. The mean pre-treatment wound diameter was 4.81 ± 0.85 cm in the placebo group, while it was 4.84 ± 0.81 cm in the topical insulin group (CI 0.29-0.35, P = 0.875). The mean post-treatment wound diameter was 3.90 ± 0.76 cm in the placebo group, while it was 2.46 ± 0.57 cm in the topical insulin group (CI 0.44-0.58, P = 0.022). The mean wound difference was 0.91 ± 0.25 cm in the placebo group, while it was 2.4 ± 0.34 cm in the topical insulin group (CI 0.40-0.20, P = 0.041). The mean percent reduction in wound diameter was 19.2 ± 4.6% in the placebo group, while it was 49.7 ± 5.2% cm in the topical insulin group (CI 10.6-6.1, P = 0.001). CONCLUSION: There was significant contraction seen in the size of the ulcer in both the study groups depicting the healing process.

Isolated Nonspecific Colonic Ulcer: A Case Report From a Tertiary Care Hospital in Pakistan.

Simple, isolated nonspecific colonic ulcer (NSCU) is a rare pathological entity which has not been adequately explored in the past literature. It is predominant between the ages of 40 and 60 years, and the most common complication is perforation which can be life threatening. Here we present a case of a young female who presented with a perforated NSCU and was successfully managed surgically.

Correlation Between Body Mass Index and Fibroadenoma.

Introduction Among all benign conditions, the fibroadenoma is the most common lesion worldwide as well as in Pakistan. Clinicians often face the dilemma of whether to remove the mass or to monitor it by means of periodic follow-up examinations. Although the removal of these lesions is a definitive solution, surgery may involve unnecessary excision of benign lesions and unbecoming cosmesis. Body mass index (BMI) is a known risk factor for the development of breast cancer.However, the relationship between BMI and benign breast diseases is still unclear. Some studies showed that increased BMI is a risk factor for benign breast diseases; however, a large number of studies showed that a decrease in BMI is the risk factor for benign breast diseases. Material and methods This was a descriptive cross-sectional study conducted at the Department of General Surgery, Pakistan Institute of Medical Sciences (PIMS), Shaheed Zulfiqar Ali Bhutto Medical University, Islamabad, Pakistan. All patients fulfilling inclusion criteria were assessed in the breast clinic of PIMS. A final diagnosis of fibroadenoma was made after a triple assessment. Weight in kilograms and height in meters were measured. All the information was recorded in a specifically designed proforma accordingly by the postgraduate trainee. BMI was calculated by the formula: BMI=Weight in kgs/height in meters. Other variables that were noted include patients' age, gender, contact number, and hospital visit. The data were analyzed using SPSS version 21 (IBM Corp., Armonk, NY, US). Results The BMI of study patients was 21.8 ± 1.3, ranging from 19 to 24.9. Out of 300 patients presenting with benign breast disease, 60 (20%) had a fibroadenoma while 240 (80%) had other benign breast diseases. Out of 136 patients with high BMI, 42 (30.8%) had a fibroadenoma while out of 74 patients with low BMI, eight (10.8%) had a fibroadenoma; however, out of 90 patients with normal BMI, 10 (11.1%) had a fibroadenoma. Our study population showed an increased risk of fibroadenoma formation in the adolescent age group with an OR value of 8.54 (CI 4.38-16.63, P<0.001). There were also additional statistical correlations between higher BMI and the site of the lesion being the upper outer quadrant of the breast (t= 4.326 P<0.01). There was no significant correlation of BMI with size and increased number of lesions (P=0.280 and P=0.175). Conclusion High BMI seems to be a substantial risk factor for the development of a fibroadenoma, particularly in young adolescent females.

Safety and Cost-effectiveness of LigaSure® in Total Thyroidectomy in Comparison with Conventional Suture Tie Technique.

INTRODUCTION: Total thyroidectomy has been considered to be a treatment of choice for thyroid malignancies. It has recently gained popularity as gold standard for benign thyroid disorders requiring surgical treatment. Because of higher number of complications associated with total thyroidectomy, it is still considered an adventurous endeavor. Most important improvements in thyroid surgery include laparoscopic thyroidectomy, energy based devices (EBD) like Harmonic Focus® and LigaSure® for dissection and hemostasis, intraoperative neuromonitoring, and parathyroid hormone (PTH) assay technology. AIM OF STUDY: Recent studies have suggested that despite lesser complication rates with LigaSure dissection method in total thyroidectomy, it is associated with prolonged operation time. Aim of our study was to compare conventional suture tie technique and LigaSure thyroidectomy, in terms of perioperative complications including bleeding, recurrent laryngeal nerve (RLN) injury, postoperative hematoma, hypocalcemia, operation time, and cost-effectiveness.  Results: This is a retrospective descriptive study done at Shifa Internationall Hospital/Shifa College of Medicine/Shifa Tameer e' Millat University, Islamabad, Pakistan from 1st of June 2016 to 1st of June 2018. One hundred and two (102) patients who underwent surgical treatment for benign thyroid diseases were included in the study. Study was done after approval from ethical committee of Shifa International Hospital/Shifa Tameer e' Millat University. Group A included patients in whom LigaSure was used for hemostasis and dissection during total thyroidectomy. Group B included patients who underwent total thyroidectomy by traditional clamp, tie, and electrocautery method for hemostasis and dissection. Frequency of female patients in group A was 45 (88.2%) and in group B was 41 (80.3%). In group A frequency of male patients was 9 (17.6%) and in group B it was 7 (13.7%). Mean operative time in group A was significantly lower (92 ± 9.61 min) than group B (123 ± 7.96 min). Mean intraoperative blood loss in group A was estimated to be 51.73 ± 5.65 mL and 139.42 ± 7.31 mL in group B. Transient hypocalcemia was the most common complication in both the groups. In group A 6.8% (n=7) patients developed transient postoperative hypocalcemia. Three patients in group B (2.9%) had transient hypocalcemia. CONCLUSION: LigaSure was significantly advantageous over conventional technique in reducing risk of complications and operation time as well as perioperative and postoperative blood loss. The reduction of operative times resulted in decreased operating room occupancy costs but the overall cost of surgery was significantly higher in LigaSure group.
