Background: Acute-on-chronic liver failure (ACLF) is associated with high mortality, but transplantation improves survival. Optimizing organ function is time-consuming and can increase infection risk. This study investigated the optimal pretransplant waiting period. Methods: In this retrospective study of patients with ACLF who underwent transplantation between January 2021 and August 2024, perioperative details and morbidity were compared between survival and mortality groups. Receiver operating characteristic (ROC) analysis was used to determine the cutoff for the pretransplant waiting period. Results: Among 112 patients with ACLF under the European Association for the Study of the Liver criteria, 61 (54.5%) underwent living donor liver transplantation (mean age, 41 years; 51 males [83.6%]). The most common etiology was viral infection (44.2%). The median Chronic Liver Failure Consortium (CLIF-C) score was 44 (respiratory failure, 14.7%; renal failure, 16.4%). There were 14 (22.9%) posttransplant deaths. The median waiting period between admission and surgery was longer in the mortality group (8 vs.4 days, P=0.2). The area under the ROC curve for the optimal pretransplant waiting period was 0.723 (P=0.01). A cutoff of 5 days predicted mortality with 71.4% sensitivity and 61.9% specificity. On univariate analysis, survivors and nonsurvivors differed significantly in age, hemoglobin level, warm ischemia time, and postoperative gastrointestinal (GI) bleeding; on multivariate analysis, postoperative GI bleeding independently predicted mortality. During a median follow-up of 17 months, no deaths occurred. Conclusions A pretransplant waiting period of 5 days predicted mortality; furthermore, postoperative GI bleeding was an independent predictor of mortality. Further studies are required to confirm these findings.

Extensive porto-mesenteric thrombosis presents a significant challenge in liver transplantation and was previously considered a contraindication. However, advancements in surgical techniques have made liver transplantation feasible. For optimal allograft function, adequate portal flow is crucial, as it generates shear stress that stimulates regeneration. In such cases, portal inflow options include the left renal vein (reno-portal anastomosis; RPA), the inferior vena cava (cavo-portal hemi-transposition; CPHT), any patent splanchnic territory, portal vein arterialization, or multi-visceral transplantation. Among these, CPHT and RPA are the most commonly performed. Generally, CPHT is used in pediatric liver transplantation; however, it is rarely reported in adult living donor liver transplantation (LDLT) due to technical challenges. In this report, we describe our technical modifications to CPHT and present the results in two patients with extensive porto-mesenteric thrombosis who underwent LDLT.

Menopause-associated estrogen deficiency has been implicated in cartilage degeneration and osteoarthritis (OA) progression. This systematic review and meta-analysis evaluates evidence from human and animal studies. Five databases were searched until March 2025. Eligible studies included postmenopausal women or ovariectomized (OVX) animal models assessing cartilage degeneration, OA severity, or related biomarkers. Human and animal studies were analyzed separately. Random-effects meta-analyses were conducted when outcomes were comparable. Eleven studies met the criteria (human, n = 6; animal, n = 5). Pooled human results for C-terminal telopeptides of type II collagen and magnetic resonance imaging-based cartilage thickness showed non-significant trends toward greater cartilage loss in estrogen-deficient women. OVX animal studies demonstrated significantly greater histological cartilage degeneration compared with controls. Hormone replacement therapy showed inconsistent but directionally protective effects. Estrogen deficiency is associated with cartilage degeneration, with strong supportive evidence from OVX models. Human evidence indicates similar trends but lacks statistical significance, highlighting the need for larger and more standardized studies.

Objective: A high rate of implant failure is frequently observed in osteoporotic spines. The majority of patients with osteoporosis are relatively old and are often unfit for general anesthesia due to various systemic comorbidities. Cement-augmented pedicle screw fixation is designed to improve stability and fixation strength in patients with compromised bone quality. Methods: A total of 45 patients (23 women and 22 men), with a mean age of 71.37 years (range, 53–94 years), diagnosed with osteoporosis (T score > -2.5) and deemed unfit for general anesthesia, underwent instrumentation with polymethylmethacrylate augmentation of cannulated pedicle screws. In total, 214 pedicle screws were inserted: 28 patients received 4 screws and 17 patients received 6 screws, all with cement augmentation. Preoperative and postoperative visual analogue scale (VAS) scores for pain, as well as Oswestry Disability Index (ODI) questionnaire data, were analyzed. Screw migration, defined as the distance from the screw tip to the anterior cortex and the upper endplate of the vertebra, was also evaluated immediately after surgery. The mean follow-up period was 15.3 months. Results: The mean preoperative VAS was 8.76 (range, 7–10). As intractable pain was the most common complaint, significant improvement was observed postoperatively: the mean postoperative VAS decreased to 2.24 (range, 0–5) (p<0.001). ODI scores also showed significant improvement in quality of life as measured by the ODI (p<0.001). Conclusion Our results support the use of cement-augmented pedicle screw fixation in medically unfit patients with osteoporosis. This technique appears effective in increasing stabilization of fixation and preventing screw loosening in this patient population. The main complication observed was cement leakage.

Objectives: Geriatric maxillofacial trauma (GMT) is not an uncommon entity in maxillofacial surgery practice. The aim of the study was to document the experience with GMT cases in a single private dental college and hospital in an effort to uncover the etiology, prevalence, fracture sites, and various types of treatment in GMT. Materials and Methods: This was a retrospective study conducted at Saveetha Dental College and Hospital in Chennai. Data from patients diag-nosed with maxillofacial trauma between January 2019 and December 2023 were retrieved from hospital records, and those aged ≥60 years wereincluded in the study. Patients’ basic demographic details and the prevalence, etiology, fracture sites, and various treatments of GMT were recorded and analyzed. The collected data were entered into a structured database and analyzed using IBM SPSS Statistics ver. 23.0 (IBM). Results: A total of 867 cases were screened, and 37 (4.04%) GMT patients were finally included in the study. The mean age of the study population was 65±5 years, and there were six females and 31 males. A ground-level fall was the common etiology (n=17), and the most common site of fracture was the mandible (n=15). Open reduction and internal fixation (ORIF) was the most common treatment modality (n=24) among included cases. Conclusion Although the prevalence of GMT was low, ground-level falls were a common reason for trauma; hence, geriatric patients require comprehensive care in home and outdoor settings. Enhanced anesthetic and surgical techniques have made ORIF a suitable treatment approach in the present era.

Background: Post-liver transplant biliary strictures are a common cause of morbidity among patients who have undergone living donor liver transplantation (LDLT). Limited data are available concerning the response rates to various treatment modalities and the long-term outcomes for these individuals. Methods: This study was a retrospective analysis of a prospectively collected database, including adult patients aged 18 years or older who underwent LDLT between 2006 and 2022. Results: Between 2006 and 2022, a total of 3,550 patients underwent liver transplantation. After applying exclusion criteria, 2,956 patients were included in the analysis.During the study period, 344 patients (11.6%) developed biliary strictures. Of these, 77.0% underwent endoscopic retrograde cholangiopancreatography as the primary treatment for biliary strictures, while the remainder received percutaneous transhepatic biliary drainage. Identified risk factors for post-liver transplant biliary strictures included the presence of multiple biliary anastomoses, bile leak, and older donor and recipient ages. The overall graft and patient survival rates were comparable between patients with and without biliary strictures, at both 1 year (93.0% vs. 96.3%) and 5 years (82.3% vs. 79.2%). Conclusions Biliary strictures are observed in approximately 11% of recipients following LDLT. While the presence of biliary strictures is associated with increased morbidity, it does not significantly impact patient survival.

The complex architecture of the papillary muscles (PMs) of the ventricles plays a crucial role in cardiac function and pathology. This comparative study aimed to examine the differences in PMs morphology between the right and left ventricles, focusing on their number, location, and shape. A total of 38 grossly normal hearts from donated bodies were dissected, and the number, location, and shape of PMs in both ventricles were observed. In this study, the left ventricle predominantly exhibited a single PM with 71.05% on the sternocostal surface and 57.89% on the diaphragmatic surface.The right ventricle showed a higher prevalence of single PM, at 89.47% on the sternocostal surface and 63.16% on the diaphragmatic surface. Broad-based shape of the PM emerged as the predominant variant, constituting 55.26% and 44.73% on the sternocostal and diaphragmatic surfaces of the left ventricle, respectively. In contrast, conical-shaped PM predominated in the right ventricle. Unique findings included “H” and “b” shaped muscles, conjoint PMs were observed exclusively in the left ventricle, and small papillary projections with direct tendinous cord attachment in the right ventricle. A distinct webbed shaped configuration of PM was exclusively observed in the right ventricle in only one specimen. No significant difference (P=0.84) was noted in muscle bellies between ventricular surfaces. This study emphasizes the complexity and variability in PM morphology, highlighting the importance of a thorough understanding of these structures for cardiothoracic surgeons, radiologists, and cardiologists to enhance interventional techniques.

Surgery for a symptomatic epiphrenic esophageal diverticulum (EED) typically involves a diverticulectomy with myotomy and partial fundoplication. A 54-year-old male patients presented with postprandial retrosternal pain and regurgitation. A contrast-enhanced computed tomography scan revealed an 8 × 6 × 7 cm left-sided EED. We planned the EED excision using the da Vinci Xi robot (Intuitive Surgical) from an abdominal transhiatal approach.The lower esophagus was looped, followed by the mobilization of the diverticulum and division of its neck using a robotic stapler. A 7-cm long esophagogastric myotomy was performed on the right side with a Toupet fundoplication. The total operative time was 240 minutes with a blood loss of 200 mL. An oral contrast study on postoperative day 1 showed no leak, and the patient was discharged the next day on an oral soft diet. The robotic transhiatal approach to treat EED is safe and may successfully overcome the difficulties of exposure and reach encountered in conventional laparoscopic surgery.

Objective: Colony-stimulating factor 1 receptor-related leukoencephalopathy (CSF1R-L) is a rare adult-onset leukoencephalopathy. Reports of CSF1R-L patients from the Indian subcontinent remain limited. We aimed to report four patients with genetically confirmed CSF1R-L from four Asian Indian families and described their clinical, molecular, and radiological features. Methods: All patients underwent clinical examination, brain magnetic resonance imaging, and whole-exome sequencing to identify causative variants in the CSF1R gene. We also reviewed published reports of Indian patients with CSF1R-L. Results: The age at enrollment ranged from 34 to 40 years. The duration of symptoms ranged from 11 months to 2 years. The chief clinical phenotype in three patients was a rapidly evolving cognitive-behavioral syndrome combined with atypical parkinsonism, and asymmetrical spastic tetraparesis was observed in one patient. We identified four different variants (three missense variants and one in-frame deletion). Radiological findings revealed white matter involvement and diffusion restriction involving the subcortical white matter and pyramidal tracts. Conclusion We expand the literature on CSF1R-L patients from India by reporting four new cases.
