Repair of moderate-to-large-sized ventral incisional hernias often requires component separation to achieve tension-free posterior layer closure. Transversus abdominis muscle release (TAR), although effective, increases operative complexity and morbidity. We describe a tissue-preserving laparoscopic transabdominal retromuscular repair with hernia sac-assisted mesh coverage without TAR. Five patients with incisional ventral hernia underwent this procedure. The hernia sac was carefully dissected while maintaining continuity with the peritoneum and used to cover the retromuscular mesh. Primary fascial closure was achieved using barbed sutures, and a polypropylene mesh was placed in the retrorectus plane. There were no intraoperative complications. Seroma occurred in three patients and resolved with conservative management without aspiration. At a median follow-up of 10 months, no recurrence or chronic pain was observed. This technique may be a feasible tissue-preserving option to facilitate posterior layer closure without TAR in selected patients, with preliminary outcomes.

Purpose::Tibial stress fracture associated with knee osteoarthritis is an unusual and difficult clinical scenario. There is no clear existing treatment guideline for this uncommon clinical disease. The aim of this study is to review the impact of various treatment options for patients with advanced knee osteoarthritis associated with proximal tibial stress fracture.Methods::The study was performed using the databases of PubMed and Scopus. Methodological index for non-randomized studies score was used to evaluate the included studies’ bias. The concluded data included the treatment approach, reported outcome measure, and time to fracture union. The literature search was started in December 2021 and accomplished in January 2022. A narrative description of the different methods and comparison of their results were done.Results::Out of total assessed 69 studies, 9 studies were included in our review. The commonest treatment approach used was total knee arthroplasty by long tibial stem extension. The mean preoperative knee society score and knee functional score were 30.62 and 23.17, respectively. The mean postoperative knee society knee score was 86.87, while the functional score was 83.52. The average reported time to achieve fracture union was 4 months (a range of 2.07 - 5.50 months).Conclusion::The optimal clinical outcome for treating either acute or mobile tibial stress fracture in patients with advanced knee osteoarthritis can be achieved with long stem total knee arthroplasty. However, due to heterogeneity of data, comparison of different treatment options for chronic proximal tibial stress fracture mal-union/non-union coexisting with knee osteoarthritic and such inferences need to be judged cautiously.

Objective:To determine the potential drug-drug interactions between anti-malarial candidate 97/78 and anti-tubercular drug rifabutin in-vivo in rats followed byin-vitro investigation of the underlying mechanisms of drug interaction.Methods: Single oral dose study was conducted in male and female rats at 40 mg/kg and 70 mg/kg for 97/78 and rifabutin respectively. Results:It was reported that rifabutin co-administration altered pharmacokinetics of 97/63 (active metabolite of 97/78). A significant decrease was reported in the systemic exposure of 97/63 by a factor of 3-4. The AUC0-last values were (4.03 ± 0.60) and (5.44 ± 1.15) μg?h?mL-1 upon 97/78 administration alone, while the values were decreased to (1.13 ± 0.10) and (1.23 ± 1.13) μg?h?mL-1 upon rifabutin co-administration in male and female rats respectively. Statistically significant differences were also reported in Cmaxand Tmax values upon rifabutin co-administration.In-vitro drug metabolism study in rat liver microsomes has shown that the metabolism of 97/63 was increased by 10%-12% upon rifabutin co-incubation. The extent of plasma protein binding of 97/63 was found to be decreased from 54%-55% to 6%-8% upon rifabutin addition.Conclusions:It was concluded that rifabutin co-administration altered PK parameters of 97/63 in SD rats. However, no intersex influences were reported in the interaction pattern. The results obtained in the in-vivo study were well correlated with thein-vitro findings and can further be applied to explore other aspects of potential drug interactions between these two drugs.

PURPOSE: To compare the efficacy and safety of latanoprost, bimatoprost, travoprost and timolol in reducing intraocular pressure (IOP) in patients with primary open angle glaucoma. METHODS: This was a prospective study conducted at a tertiary-care centre. One hundred and forty patients with newly diagnosed primary open angle glaucoma were randomly assigned to treatment with latanoprost (0.005%), bimatoprost (0.03%), travoprost (0.004%) or timolol gel (0.5%); 35 patients were assigned to each group. All patients were followed for 2, 6, and 12 weeks. The main outcome measure studied was the change in IOP at week 12 from the baseline values. Safety measures included recording of adverse events. RESULTS: The mean IOP reduction from baseline at week 12 was significantly more with bimatoprost (8.8 mmHg, 35.9%) than with latanoprost (7.3 mmHg, 29.9%), travoprost (7.6 mmHg, 30.8%) or timolol (6.7 mmHg, 26.6%) (ANOVA and Student's t-tests, p < 0.001). Among the prostaglandins studied, bimatoprost produced a maximum reduction in IOP (-2.71; 95% confidence interval [CI], -2.25 to -3.18) followed by travoprost (-1.27; 95% CI, -0.81 to -1.27) and latanoprost (-1.25; 95% CI, -0.79 to -1.71); these values were significant when compared to timolol at week 12 (Bonferroni test, p < 0.001). Latanoprost and travoprost were comparable in their ability to reduce IOP at each patient visit. Ocular adverse-events were found in almost equal proportion in patients treated with bimatoprost (41.3%) and travoprost (41.9%), with a higher incidence of conjunctival hyperemia (24.1%) seen in the bimatoprost group. Timolol produced a significant drop in heart rate (p < 0.001) at week 12 when compared to the baseline measurements. CONCLUSIONS: Bimatoprost showed greater efficacy when compared to the other prostaglandins, and timolol was the most efficacious at lowering the IOP. Conjunctional hyperemia was mainly seen with bimatoprost. However, the drug was tolerated well and found to be safe.

Sudden ascent to high altitudes beyond 2,438 m can cause life-threatening complications such as acute mountain sickness and high altitude cerebral and pulmonary oedema. We present a case of pituitary apoplexy in a young man who ascended to high altitude gradually, after proper acclimatisation. He developed headache, nausea, vomiting and persistent hypotension. Magnetic resonance imaging revealed an enlarged pituitary gland with haemorrhage. His hormonal estimation showed acute adrenal insufficiency due to corticotropin deficiency. The patient responded well to conservative medical management with hormonal replacement therapy. This is most likely the first reported case of high altitude-induced pituitary apoplexy in the literature.
