Given the other known advantages of sequential hydrosonography and HyFoSy, this test is worth including in the initial workup for infertile patients.
Sequential hydrosonography and HyFoSy is a promising method for assessing the uterine cavity and tubal patency in women undergoing infertility workup. The findings suggest that the procedure may increase the chance of a spontaneous pregnancy following the procedure. Given the other known advantages of sequential hydrosonography and HyFoSy, this test is worth including in the initial workup for infertile patients.
Pediatric acute bacterial rhinosinusitis (ABRS) is often treated with oral antibiotics, with limited insight into adverse effects (AEs) across drug classes. In this systematic review and meta-analysis, we characterize AE incidence associated with oral antibiotics in these patients.

We searched PubMed and Embase for English-language articles published from 1985 to September 2020 reporting AEs of oral antibiotic therapy for ABRS patients aged 0-18 years. Six-hundred and sixty-six articles underwent title and abstract screening, identifying 154 articles for full-length review.

Eleven articles were included, most of which reported individual and aggregate AE incidences. Amoxicillin/clavulanate, amoxicillin, cephalosporin/carbacephem, and placebo groups were identified. Random-effects meta-analysis of prospective groups identified appreciable incidences of diarrhea and abdominal pain, and low incidence of rash, for amoxicillin-clavulanate and amoxicillin. All antibiotics as well as placebo were associated with non-zero overall AE incidence. Children receiving antibiotics were about twice as likely to incur any AE during treatment in placebo-controlled studies, though this association was not significant. High heterogeneity limited most point estimates, with risk of bias, typically in outcomes measurement, detected in most studies.

Reporting of AEs associated with oral antibiotic use in pediatric ABRS is limited in current literature. Adverse effects are non-negligible, but may not significantly exceed placebo.

The global burden of non-alcoholic fatty liver disease (NAFLD) and NAFLD-associated hepatocellular carcinoma (HCC) is steadily rising. Cas9 inhibitor We pursued to investigate the results after liver resection for NAFLD-HCC versus hepatitis B virus (HBV)-HCC exploiting Kaplan Meier method, log-rank test and uni/multivariate analysis with the logistic regression models".

Patients who underwent liver resection for HCC between January 2004 and December 2018 were included. The outcomes of NAFLD-associated HCC were analyzed.

The prevalence of NAFLD-associated HCC was 8.4%. A significant number of NAFLD patients had no cirrhosis (21 patients; 38.8%). Although NAFLD patients had a significantly better 5-year survival (P=0.033), NAFLD was not significantly associated with overall survival in multivariate analysis (P=0.287). However, survival after 5 years declined in NAFLD patients and was similar to HBV. NAFLD was protective against systemic recurrence compared with HBV (P=0.018), and this was confirmed in multivariate analywer systemic recurrence compared to HBV-associated HCC.
Clavicle fractures are less commonly managed under regional anesthesia compared to general anesthesia. The study highlights the advantage of regional anesthesia in reducing the risk of aerosol generation and viral transmission during the times of COVID-19 and avoiding the complications associated with general anesthesia.

We report a case of 42years old COVID-19 positive male with a left clavicle fracture due to a fall from a tree, who was managed under regional anesthesia with open reduction and internal fixation. A combination of interscalene brachial plexus and superficial cervical plexus block was performed.

The dual innervation of the clavicle makes combined interscalene brachial plexus and superficial cervical plexus block an effective method of anesthesia for clavicle surgery. It provides better analgesia, has fewer postoperative complications, less infection transmission via aerosol, and earlier hospital discharge as compared to general anesthesia.

Ultrasound-guided combined interscalene brachial plexus and superficial cervical plexus block can be used as a safe anesthetic technique in clavicle surgery.

Caustic ingestion causes high mortality and morbidity, so it is necessary to perform effective management for this case, especially in low-resource settings.

A 58-year-old male with caustic intoxication. The patient had acute complications in the form of hematemesis caused by gastric burns. The patient underwent immediate endoscopy and a Grade-IV Zargar gastric injury was noted. The patient was treated conservatively. He was given nutrition, proton pump inhibitors, antibiotics, and other supportive therapy during treatment.

Insertion of a nasogastric tube in patients with caustic ingestion should be carried out after endoscopy or during endoscopy.

Endoscopy plays an important role in the acute management of caustic ingestion.

Myoepithelial tumors are under-recognized neoplasms that could be difficult to identify due to their rarity and limited comprehension. Their diverse morphology, varied cytologic features and heterogenous immunohistochemical characteristics create a significant diagnostic challenge.

We report the case of a 72-year-old-male patient who received conservative treatment during one year for a popliteal mass on the right knee that showed synovial hyperplasia (benign findings) at initial open tissue biopsy. New symptoms of popliteal area enlargement and discomfort required a second incisional biopsy to reach the diagnosis of a soft tissue myoepithelial tumor through tissue analysis and immunohistochemical staining.

The myoepithelial tumors represent a medical dilemma due to their heterogenic features requiring high level of suspicion and adequate immunohistochemical markers for their diagnosis.

Orthopaedic surgeons should be aware of the atypical presentation of these rare neoplasms to provide an early diagnosis and adequate management.

Scar endometriosis is an uncommon variant of extra pelvic endometriosis, which develops at the scar site of previous abdominopelvic surgery and is seen in women during their reproductive period.

We report a 38-year-old female who presented with a nine-months history of a painful ulcerative mass that developed on a cesarean section scar. The mass was removed by a wide excision and confirmed by histology to be endometriosis.

Wide surgical resection of ectopic endometriosis is the treatment of choice. It is usually curative and ensures the confirmation of the diagnosis.

Cesarean section scar endometriosis can undergo malignant transformation. This case highlights the need for early detection and treatment.

Hirschsprung's disease is a gastrointestinal anomaly affecting neuronal development and function. The primary abnormality is the absent ganglionic cells in the submucosal and myenteric neural plexuses. Disease presentation can vary, and patients may present with delayed meconium passage or late in adulthood. Total colonic aganglionosis is considered a rare subtype and even rarer to extend proximally into the small bowel. Therefore, adult Hirschsprung disease is frequently misdiagnosed as chronic constipation until comorbid events such as volvulus or perforation occur.

A 34years South-Sudanese male presented with chronic constipation since early childhood, abdominal discomfort, pain, and distension. His bowel habits were infrequent, requiring occasional enemas. A strong family history of Hirschsprung disease was identified. He underwent total abdominal colectomy and end ileostomy. Postoperative diagnosis of TCA and small bowel extension of more than 50cm was confirmed. The patient was discharged home aftereved, but we recommend an ileostomy for such cases.
Ventral hernia repair is one of the most common surgeries performed in the United States. Failure of hernia repairs can be attributed to sutures pulling through tissue or mesh (anchor point failure). T-Line Hernia Mesh is the first mesh designed to specifically prevent anchor point failure by distributing tension. This case study of two patients is the first clinical application of the novel T-Line Hernia Mesh.

Two separate patients presented with symptomatic ventral hernia secondary to previous laparotomy. Patient 1 is a fifty-five year-old male who underwent open ventral hernia repair with T-Line Hernia Mesh onlay placement. Patient 2 is a fifty-eight year-old female with a symptomatic ventral hernia that underwent bilateral component separation and primary hernia repair with T-Line Hernia Mesh. Both patients postoperative course was uneventful with no reported surgical site occurrences or hernia recurrence.

T-Line Hernia Mesh provides a new innovative approach to hernia surgery. This provides the first clinical outcomes. No complications were observed. In addition, this manuscript also demonstrates the surgical technique for the first time.

This cases and technical description provides the initial report for a new designed T-Line Hernia Mesh that could result in a paradigm shift in hernia surgery concepts.

Extensor pollicis longus (EPL) tendon injury is a major complication in distal radial fracture repair. The risk factors for EPL tendon injury are prominent dorsal screws, direct intraoperative damage through drilling, and/or dorsal roof fragments. Herein, we introduce a simple technique to minimize the risk of EPL tendon rupture after volar plate fixation of distal radial fracture.

The patient was a 67-year-old woman with an intra-articular unstable distal radial fracture treated by volar locking plate fixation. Intraoperatively, we opened the third compartment after screw fixation. Because the screw had penetrated the floor of the third compartment, we moved the EPL tendon out of its groove and closed the third compartment by suturing the retinaculum. We confirmed that the EPL tendon was intact 7years postoperatively, even though the screw was prominent in the third compartment.

After volar plate fixation of the distal radial fracture, we partially open the third compartment through an approximately 2-cm-long incision on the ulnar side of Lister's tubercle. If the screw is prominent in the third compartment, we completely open the third compartment, take the EPL tendon out of its groove, and close the compartment by suturing the retinaculum. Our method was proved useful because the EPL tendon has remained intact for 7years with the screw protruding into the third compartment.

Our surgical technique is useful to prevent secondary EPL tendon rupture after distal radial plate fixation.
