A delayed presentation of traumatic diaphragmatic hernia in a young male: a unusual case report and comprehensive review of literature.

Acquired diaphragmatic hernia is typically caused by blunt trauma to the abdomen. It can be challenging to diagnose in acute cases due to a wide range of symptoms. Delayed presentation of traumatic diaphragmatic hernia is uncommon and can lead to respiratory issues or bowel complications like incarceration, perforation, or strangulation. Computed tomography is the preferred diagnostic tool. For acute case, laparotomy is indicated traditionally; however, the choice of surgery is dependent upon the surgeon's expertise and availability of resources.

A comparative study on effects of defect closure versus non-closure in laparoscopic totally extraperitoneal repair of direct inguinal hernia.

Introduction: Totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) repair are the principal techniques in laparoscopic hernia repair. Seroma formation and pain are frequent complications of moderate-large size laparoscopic direct inguinal hernia mesh repair. This study was conducted to evaluate the feasibility of defect closure in moderate-large direct inguinal hernias and its effect on various outcomes. Method: This is a prospective cohort study from September 2020 to August 2021, where a total of 88 patients with uncomplicated direct inguinal hernia (M3 or more) were enrolled in the study and divided into two equal groups of TEP defect closure and non-closure, and various outcome measures were noted. Results: The majority of patients were male (94.31%), with a mean age range of 18-85 years, and had right-sided inguinal hernia (46.5%). Seroma formation at 10th POD in the defect closure and non-closure were 24% and 33% (p value: 0.225), which reduced to 11% and 18%, respectively, at 1 month (p value: 1.000). All seromas resolved within 6 months. Pain in VAS at 10th POD in the defect closure and non-closure were 1.55±0.571 and 1.38±0.527, respectively (p value: 0.121), which gradually decreased to 1.20±0.524 and 1.16±0.420 at a 6-month interval (p value: 0.689). The mean operative time in the bilateral and unilateral defect closure groups was 72.3±4.1 and 56.5±4.3 min, respectively, whereas that in the bilateral and unilateral defect non-closure groups was 62.3±3.7 and 45.7±3.6 min, respectively. Conclusion: The defect closure was found to have higher pain and less seroma formation at various intervals of time following TEP for moderate-large direct inguinal hernia. Although these findings were statistically insignificant, they may be clinically significant, and further studies with a larger sample size are suggested.

Strain fingerprinting of exciton valley character in 2D semiconductors.

Intervalley excitons with electron and hole wavefunctions residing in different valleys determine the long-range transport and dynamics observed in many semiconductors. However, these excitons with vanishing oscillator strength do not directly couple to light and, hence, remain largely unstudied. Here, we develop a simple nanomechanical technique to control the energy hierarchy of valleys via their contrasting response to mechanical strain. We use our technique to discover previously inaccessible intervalley excitons associated with K, Γ, or Q valleys in prototypical 2D semiconductors WSe2 and WS2. We also demonstrate a new brightening mechanism, rendering an otherwise "dark" intervalley exciton visible via strain-controlled hybridization with an intravalley exciton. Moreover, we classify various localized excitons from their distinct strain response and achieve large tuning of their energy. Overall, our valley engineering approach establishes a new way to identify intervalley excitons and control their interactions in a diverse class of 2D systems.

Global treatment of haemorrhoids-A worldwide snapshot audit conducted by the International Society of University Colon and Rectal Surgeons.

AIM: There is no universally accepted treatment consensus for haemorrhoids, and thus, management has been individualized all over the world. This study was conducted to assess a global view of how surgeons manage haemorrhoids. METHODS: The research panel of the International Society of University Colon and Rectal Surgeons (ISUCRS) developed a voluntary, anonymous questionnaire evaluating surgeons' experience, volume and treatment approaches to haemorrhoids. The 44 multiple-choice questionnaire was available for one month via the ISUCRS email database and the social media platforms Viber and WhatsApp. RESULTS: The survey was completed by 1005 surgeons from 103 countries; 931 (92.6%) were in active practice, 819 (81.5%) were between 30 and 60 years of age, and 822 (81.8%) were male. Detailed patient history (92.9%), perineal inspection (91.2%), and digital rectal examination (91.1%) were the most common assessment methods. For internal haemorrhoids, 924 (91.9%) of participants graded them I-IV, with the degree of haemorrhoids being the most important factor considered to determine the treatment approach (76.3%). The most common nonprocedural/conservative treatment consisted of increased daily fibre intake (86.9%), increased water intake (82.7%), and normalization of bowel habits/toilet training (74.4%). Conservative treatment was the first-line treatment for symptomatic first (92.5%), second (72.4%) and third (47.3%) degree haemorrhoids; however, surgery was the first-line treatment for symptomatic fourth degree haemorrhoids (77.6%). Rubber band ligation was the second-line treatment in first (50.7%) and second (47.2%) degree haemorrhoids, whereas surgery was the second-line treatment in third (82.9%) and fourth (16.7%) degree symptomatic haemorrhoids. Rubber band ligation was performed in the office by 645(64.2%) of the participants. The most common surgical procedure performed for haemorrhoids was an excisional haemorrhoidectomy for both internal (87.1%) and external (89.7%) haemorrhoids - with 716 (71.2%) of participants removing 1, 2 or 3 sectors as necessary. CONCLUSION: Although there is no global haemorrhoidal treatment consensus, there are many practice similarities among the different cultures, resources, volume and experience of surgeons around the world. With additional studies, a consensus statement could potentially be developed.

Early bladder dysfunction after vesicovaginal fistula repair: A prospective comparative analysis of transvaginal, open, and laparoscopic abdominal approaches.

INTRODUCTION: We aim to compare the clinical and urodynamic profile of lower urinary tract symptoms (LUTS) in patients undergoing laparoscopic, open transabdominal, and laparoscopic transabdominal vesicovaginal fistulae (VVF) repair at 3 months of repair, that is, in early postoperative period. MATERIALS AND METHODS: Fifty-one consecutive patients with endoscopically confirmed VVF were enrolled in our study over 2 years. Malignant fistulae, radiation-induced, and complex fistulae were excluded after cross-sectional imaging. All patients underwent a postoperative assessment for the success of the repair. Then at 3 months, they completed the American Urological Association Symptom Score questionnaire and underwent a dual channel pressure-flow urodynamic study. The results of transvaginal, laparoscopic, and open transabdominal repairs were compared. RESULTS: All patients belonged to the Indian Caucasian race. The mean age was 35.43 ± 6.63 years. Thirty-two patients had supratrigonal and 19 had trigonal fistulae. Laparoscopic transabdominal repair was done in 15 patients, open transabdominal repair in 22 patients, and transvaginal repair in 14 patients. Forty-six patients reported some LUTS at a median follow-up of 5.83 ± 2.37 months postoperatively. Only 18 (35.2%) of these patients had moderate to severe symptoms The postoperative bladder dysfunction rates in open transabdominal, transvaginal and laparoscopic transabdominal groups were 36.4%, 28.6%, and 20%, respectively. Twenty-seven patients (52.9%) had some urodynamic abnormality, that is, small capacity (5), high voiding pressures (14), genuine stress incontinence (3), and poor compliance (3). Bladder capacity was a significant predictor of bladder dysfunction in our patients. CONCLUSIONS: In our study, all three surgical approaches were associated with bladder dysfunction, however, it was the least in the laparoscopic transabdominal approach. Postoperative bladder capacity is a significant predictor of bladder dysfunction.

Safety and efficacy of parsaclisib in combination with rituximab, bendamustine + rituximab, or ibrutinib in patients with previously treated B-cell lymphoma: analysis of a phase 1 dose-finding study (CITADEL­112).

Parsaclisib, a potent and highly selective phosphoinositide 3-kinase δ inhibitor, has shown clinical activity in relapsed/refractory (R/R) B-cell lymphoma. The phase 1 CITADEL-112 (NCT03424122) study assessed safety and efficacy of parsaclisib in combination with investigator choice standard of care (SOC; rituximab [Treatment A], rituximab plus bendamustine [Treatment B], or ibrutinib [Treatment C]) in 50 patients with R/R B-cell lymphoma. The most common treatment-emergent adverse events included neutropenia (62.5%, 50.0%, and 50.0% of patients in Treatments A, B, and C, respectively); diarrhea (37.5%) and anemia (31.3%) in Treatment A; abdominal pain, asthenia, diarrhea, and nausea (each 33.3%) in Treatment B; and increased alanine and aspartate aminotransferase (each 37.5%) in Treatment C. Objective responses were observed in 13 patients (81.3%) in Treatment A, 10 (55.6%) in Treatment B, and 8 (50.0%) in Treatment C. Parsaclisib combined with SOC therapies had an expected safety profile and promising efficacy in patients with R/R B-cell lymphomas.

Acute intestinal obstruction secondary to ingested foreign body in an adult with autism spectrum disorder: A rare case report and review of literature.

Key Clinical Message: Foreign body ingestion is common in pediatric age group however can be found in any age group with intellectual disability and neurodevelopmental delay. There is usually a delay in presentation and interventions following foreign body ingestion in patients with neurodevelopmental delay, leading to increased morbidity, mortality, and complications owing to inability of such patients giving relevant history. Most ingested foreign bodies naturally pass through the digestive tract without untoward effects. Only a few patients may require surgical interventions. Principle of management should be to reduce anxiety among patients and their visitors. Speedy recovery is enhanced so that they can return to their familiar environment soon. Abstract: Foreign body ingestion is common in pediatric populations and may be found in any age group with intellectual disability and neurodevelopmental delay. As the patient cannot give a clear and relevant history, there is usually a delay in presentation and interventions following foreign body ingestion in patients with neurodevelopmental delay, leading to increased morbidity, mortality, and complications. Most foreign bodies pass through the digestive system without any complications, and very few require surgical intervention. The goal should be to reduce anxiety among patients and their visitors and to enhance speedy recovery so that they can return to their familiar environment soon. Here we report a case of Acute intestinal obstruction secondary to ingestion of the head portion of a doll which was managed with emergency laparotomy with enterotomy and removal of foreign body in a 16 years female with Autism Spectrum Disorder.

Safety and efficacy of zandelisib plus zanubrutinib in previously treated follicular and mantle cell lymphomas.

The combination of the phosphatidylinositol 3-kinase delta (PI3Kδ) inhibitor zandelisib with the Bruton's tyrosine kinase (BTK) inhibitor zanubrutinib was hypothesized to be synergistic and prevent resistance to single-agent therapy. This phase 1 study (NCT02914938) included a dose-finding stage in patients with relapsed/refractory (R/R) B-cell malignancies (n = 20) and disease-specific expansion cohorts in follicular lymphoma (FL; n = 31) or mantle cell lymphoma (MCL; n = 19). The recommended phase 2 dose was zandelisib 60 mg on Days 1-7 plus zanubrutinib 80 mg twice daily continuously in 28-day cycle. In the total population, the most common adverse events (AEs; all grades/grade 3-4) were neutropenia (35%/24%), diarrhoea (33%/2%), thrombocytopenia (32%/8%), anaemia (27%/8%), increased creatinine (25%/0%), contusion (21%/0%), fatigue (21%/2%), nausea (21%/2%) and increased aspartate aminotransferase (24%/6%). Three patients discontinued due to AEs. The overall response rate was 87% (complete response [CR] = 33%) for FL and 74% (CR = 47%) for MCL. The median duration of response and progression-free survival (PFS) were not reached in either group. The estimated 1-year PFS was 72.3% (95% confidence interval [CI], 51.9-85.1) for FL and 56.3% (95% CI, 28.9-76.7) for MCL (median follow-up: 16.5 and 10.9 months respectively). Zandelisib plus zanubrutinib was associated with high response rates and no increased toxicity compared to either agent alone.

Traumatic Abdominal wall hernia with ileal perforation following blunt trauma abdomen: A rare case report and review of literature.

Blunt trauma abdomen with abdominal wall herniation with bowel perforation is an acute emergency condition. Road traffic accidents causing blunt trauma are common in a youngster like in our case. Once the patient is resuscitated, ultrasonography and Computed tomography must be done. Early surgical exploration with mesh or primary repair of the defect is the mainstay of management. We have a case of a 25-year-old male with blunt trauma abdomen and anterior wall hernia following a road traffic accident who was managed with emergency exploratory laparotomy as computed tomography suggested anterior abdominal wall herniation of bowel content.

Malignant rectal GIST managed with chemotherapy (Imatinib Mesylate): A case report and a comprehensive review.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors involving the gastrointestinal tract, arising from the interstitial cells of Cajal. GIST comprises about 1% of all GI tumors. Rectal GISTs are rare and comprise of approximately 5% of all GISTs and only 0.1% of rectal tumors are found to be GISTs. Rectal GISTs may be diagnosed incidentally or present with symptoms, including defecation problems, bleeding, and/or pain. We report a case of a 46-year-old male with rectal GIST metastasized to the liver and bilateral lung parenchyma managed by Imatinib Mesylate (IM) regimen. Rectal GIST although being rare, must be considered as a differential diagnosis in a patient presenting with defecatory problems with bleeding.
