RESUMO
AIM: The main goal of this work was to highlight the significance of redox imbalance in the pathophysiology of bacterial vaginosis (BV). We studied the pro-oxidant (malondialdehyde) and antioxidants (glutathione, total antioxidant capacity) in the vaginal fluids of women and compared them on the basis of their Nugent score (NS). METHODS: Women were clinically screened using Amsel criteria (≥2 were regarded as positive) and were further screened for NS on the basis of microscopic examination. Subjects were classified into one of three groups - healthy controls, intermediate, and BV - on the basis of NS (0-3, 4-6, and 7-10, respectively). High vaginal swabs were collected from the study participants in order to estimate the levels of pro and antioxidants in the vaginal fluids. RESULTS: Our results indicated that levels of both pro- and antioxidants were elevated in high vaginal swabs of women in the intermediate (NS: 4-6) and BV (NS: 7-10) groups as compared to those of healthy control women. The difference in mean values for total antioxidant capacity and glutathione was found to be statistically significant. Furthermore, in the BV group (NS: ≥7) both antioxidants (glutathione and total antioxidant capacity) and the pro-oxidant, malondialdehyde, were found to be negatively correlated to NS. Interestingly, the correlation between NS and malondialdehyde was statistically significant. CONCLUSION: Our results suggest a significant correlation between redox imbalance and NS, which signifies changes in vaginal ecology from normal flora (Lactobacillus spp.) towards a more mixed bacterial population representing BV.

BACKGROUND: With the introduction of neoadjuvant chemoradiotherapy in patients with esophageal carcinoma, nutritional access has become essential to counter deleterious effects of dysphagia. Current NCCN guidelines do not recommend PEG prior to esophagectomy in these patients, but there is little evidence for this recommendation. The objective of this study was to compare outcomes in patients who underwent esophagectomy with or without prior PEG placement. METHODS: We retrospectively reviewed 96 patients who underwent esophagectomy between 2005 and 2012 for esophageal carcinoma. Patients were divided into two groups; Group I (PEG +ve) and Group II (PEG -ve). Patient characteristics, operative variables, and post-operative complications were compared. χ (2) and Fisher's test were used for categorical, while t test was used for interval variables. RESULTS: Median age was 51(18-70) years. Lower thoracic tumors were more common in Group I (69 vs. 63 %) (P = 0.04) and more patients underwent minimally invasive surgery in this group (50 vs. 2.6 %) (P < 0.0001). Mean blood loss (326 vs. 465 ml) (P = 0.02) and ICU stay (1.6 vs. 4.3 days) (P = 0.01) were significantly lower in Group I. There was no 30-day mortality in Group I versus 10.5 % in Group II (P = 0.01). No significant difference in anastomotic leak and stricture rate was observed. Gastric conduit was used in all patients for reconstruction. One patient had malignancy in PEG site biopsy. CONCLUSION: Percutaneous endoscopic gastrostomy before esophagectomy is safe and does not adversely impact post-operative outcomes.

BACKGROUND: Long-term medical and quality of life (QOL) outcomes in voluntary liver donors remain under investigated. The objective of the current study was to report long-term medical outcomes and re-evaluate QOL in living liver donors. METHODS: This was a single-center retrospective cohort study of donors who underwent donor hepatectomy between 2012 and 2018. We investigated long-term outcomes in 7 domains. These include medical problems, surgical procedures, work-related issues, pregnancy outcomes, psychiatric interventions, willingness to donate again, and long-term mortality. QOL was evaluated using short-form 36. RESULTS: The median follow-up time was 61.4 months (53.3-83.7). Among 698 donors, 80 (11.5%) experienced medical problems, 4 (0.6%) had work-related issues, and 20 (2.9%) needed psychiatric assistance. Surgery was performed in 49 donors (7%), and females were more likely to have undergone incisional hernia repair (5.8% vs 1.9%, P = .006). There were 79 postdonation pregnancies including 41 normal vaginal deliveries (51.9%), 35 cesarean sections (44.3%), and 3 miscarriages (3.8%). Willingness to donate again was reported by 658 donors (94.3%). Donors whose recipients were alive were more likely to donate again (95.5% vs 90.5%, P = .01). There were 3 deaths (0.4%) in the long-term. The mean physical composite score at initial and follow-up evaluation was 86.7 ± 13.9 and 76.5 ± 20.9 (P = .001), and the mean mental composite score at initial and follow-up evaluation was 92.1 ± 13.5 and 80.7 ± 16 (P = .001). CONCLUSION: The overall long-term outlook in living liver donors is promising. QOL parameters might deteriorate over time and frequent re-evaluation might be considered.

Background: In deceased donor liver transplantation (DDLT), transplant eligibility for T3-T4 HCC requires successful downstaging (DS). Living donor liver transplantation (LDLT) can be considered selectively in these patients without DS, but its role is not defined. The objective of the current study was to assess outcomes of LDLT for HCC based on UNOS staging with no prior DS. Materials and Methods: Patients who underwent LDLT for HCC (n = 262) were staged based on modified UNOS TNM staging. High-risk factors were identified and 5-year recurrence free survival was compared in patients with T2-T4 HCC. Results: Median follow-up was 30.2 (16.4-46.3) months. Recurrence rate in T1, T2, T3, T4a, and T4b HCC was 0, 10.1, 16.1, 5.9, and 37.5% (P = 0.02), respectively. On multivariate analysis, AFP > 600 ng/mL [HR:11.7, P < 0.001] and T4b HCC (macrovascular invasion) [HR = 5.6, P = 0.03] were predictors of recurrence. After exclusion of AFP > 600 ng/mL, 5-year RFS for T2, T3, and T4a HCC was 94, 86, and 92% (P = 0.3). Rate of microvascular invasion between T2 and T3 HCC was 24.3 vs. 53.6% (P = 0.005), and between T2 and T4a HCC was 24.3 vs. 36.7% (P = 0.2). Overall, 26 (19.4%) patients were overstaged and 23 (17.1%) were understaged on preoperative imaging. The 5-year RFS in patients with identical preoperative and histopathological staging was 94, 87, and 94% (P = 0.6). Conclusion: LDLT without prior DS leads to comparable survival for UNOS T2, T3, and T4a HCC as long as AFP is < 600 ng/mL.
RESUMO
Hepatocellular carcinoma (HCC) ranks second amongst all causes of cancer deaths globally. It is on a rise in Pakistan and might represent the most common cancer in adult males. Pakistan contributes significantly to global burden of hepatitis C, which is a known risk factor for HCC, and has one of the highest prevalence rates (>3%) in the world. In the absence of a national cancer registry and screening programs, prevalence of hepatitis and HCC only represents estimates of the real magnitude of this problem. In this review, we present various aspects of HCC in Pakistan, comparing and contrasting it with the global trends in cancer care. There is a general lack of awareness regarding risk factors of HCC in Pakistani population and prevalence of hepatitis C has increased. In addition, less common risk factors are also on a rise. Majority of patients present with advanced HCC and are not eligible for definitive treatment. We have attempted to highlight issues that have a significant bearing on HCC outcome in Pakistan. A set of strategies have been put forth that can potentially help reduce incidence and improve HCC outcome on national level.
RESUMO
Adrenal metastasis from ovarian malignancy is extremely rare. Very few cases in literature have reported surgical removal of isolated adrenal metastasis in patients with ovarian carcinoma. Presence of horse shoe kidney can impose technical challenges in patients planned for laparoscopic adrenalectomy. A52 years female with high grade serous carcinoma ovary, horse shoe kidney and previous history of two laparotomies for primary malignancy developed adrenal metastasis 3 years after diagnosis of the primary lesion. She underwent laparoscopic left adrenalectomy in right lateral position. She was discharged on the second postoperative day. Laparoscopic adrenalectomy for ovarian metastasis in a patient with horse shoe kidney has not been reported before. Surgical resection of solitary adrenal metastasis offers survival benefit and laparoscopic resection should always be a treatment option in these patients.

BACKGROUND: Distance from anal verge and abdominoperineal resection are risk factors for circumferential resection margin (CRM) positivity in rectal cancer. Induction chemotherapy (IC) before concurrent chemoradiation (CRT) has emerged as a new treatment modification. Impact of IC before concurrent CRT on CRM positivity in low rectal cancer remains to be independently studied. The objective of this study was to determine CRM positivity in low rectal cancer, with and without prior IC, and to identify predictors of disease free and overall survival. MATERIALS AND METHODS: Patients who underwent surgery for rectal cancer between 2005 and 2011 were retrospectively reviewed and divided into two groups. Group 1 received IC before CRT and Group 2 did not. Demographics, clinicopathological variables and CRM status were compared. Actuarial 5 year disease free survival (DFS), overall survival (OS) and independent predictors of survival were determined. RESULTS: Patients in the IC group presented with advanced stage (Stage 3=89.2% versus 75.4%) (P=0.02) but a high rate of total mesorectal excision (TME) (100% versus 93.4%) (P=0.01) and sphincter preservation surgery (54.9 % versus 22.9%) (P=0.001). Patients with low rectal cancer who received IC had a significantly low positive CRM rate (9.2% versus 34%) (P=0.002). Actuarial 5 year DFS in IC and no IC groups were 39% and 43% (P=0.9) and 5 year OS were 70% and 47% (P=0.003). Pathological tumor size [HR: 2.2, CI: 1.1-4.5, P=0.01] and nodal involvement [HR: 2, CI: 1.08-4, P=0.02] were independent predictors of relapse while pathological nodal involvement [HR: 2.6, CI: 1.3-4.9, P=0.003] and IC [HR: 0.7, CI: 0.5-0.9, P=0.02] were independent predictors of death. CONCLUSIONS: In low rectal cancer, induction chemotherapy before CRT may significantly decrease CRM positivity and improve 5 year overall survival.
