Pneumoperitoneum usually requires emergency surgery. Asymptomatic idiopathic pneumoperitoneum is a rare subgroup of pneumoperitoneum for which a management algorithm has not been established.

In an 88-year-old female patient, pneumoperitoneum was found incidentally by chest computed tomography during a periodic follow-up for sarcoidosis. Emergency admission was ordered for conservative treatment. Upper gastrointestinal endoscopy revealed edematous mucosa in the entire gastric vestibule. After being discharged on the 7th day, her clinical course was uneventful over 2months of follow-up.

The initial clinical manifestations of pneumoperitoneum are variable and range widely from asymptomatic to septic shock. The etiology of pneumoperitoneum in our patient implied a subclinical visceral perforation that resolved without treatment. We advocate an algorithm for the initial management of pneumoperitoneum according to the extent of peritonitis and impaired conditions.

Incidentally found asymptomatic pneumoperitoneum does not always require intervention. Careful and repeated physical assessment with investigation of underlying etiology is important in the management of pneumoperitoneum.

Shoulder manipulation under ultrasound-guided cervical nerve root block (MUC) gives good clinical results in patients with frozen shoulder 1week after the procedure. However, some patients are refractory to MUC. The present study was performed to investigate the prognostic factors of MUC for frozen shoulder.

We evaluated 73 frozen shoulders (70 patients) to investigate the prognostic factors of MUC. The patients' mean age was 56.6years, and 60% were female. The mean duration of symptoms before MUC was 8.6months. We assessed pain using a numeric rating scale (NRS), range of motion (ROM), and the American Shoulder and Elbow Surgeons (ASES) score before and 1year after MUC. We compared patients with an ASES score of <80 (defined as a poor clinical result) with those with an ASES score of ≥80 (good clinical result). To identify the risk factors for a poor clinical result, multiple logistic regression analysis was performed using the following variables age, sex, duration of symptoms before MUC, diabetes mellitus (DM), initial NRS score, and initial ROM.

The initial NRS score and the prevalence of DM were significantly greater in the poor clinical results group. Multiple logistic regression analysis revealed that DM was the only independent risk factor for a poor clinical result after MUC (odds ratio, 51; 95% confidence interval, 10.9-237; p=.01).

DM is a negative prognostic factor of MUC for frozen shoulder, and patients with DM should be informed of this before they undergo treatment for frozen shoulder.

Despite the fact that hydatid disease is endemic in some countries, its cervical location remains very rare.

We report two cases of primary cervical hydatid disease in two children from rural areas. The imaging was not specific, since the location is rare; the diagnosis was only confirmed after surgery.

Hydatid cyst is a rare pathology. Thus clinical presentation, radiological examinations, fine needle aspiration and serology can be useful to suspect the diagnosis.

Hydatid disease should be considered when dealing with slow-growing renitent neck swelling in endemic countries.

Isolated gallbladder tuberculosis is extremely rare even in endemic regions posing diagnostic challenges as the presentation mimics other gallbladder diseases such as cholecystitis and gallbladder carcinoma. Preoperative suspicion index is negligible with most cases being diagnosed postoperatively from resected specimen.

Herein, we report an elderly man who presented with jaundice, and was clinically diagnosed with gallbladder carcinoma.

Histopathology of resected gallbladder revealed gallbladder tuberculosis. No features of tuberculous infection were found elsewhere.

Healthcare providers should have a high index of suspicion particularly for patients in endemic areas presenting with cholecystitis to obtain a pre-operative diagnosis.

Damage to the adventitial layer of an artery leads to pseudoaneurysm formation. Pseudoaneurysms caused by complications of orthopaedic constructs are rare.

Case report 01. A 27-year-old male presented with acute bleeding from an external fixator pin site. He had defaulted follow-up due to covid pandemic and presented with malunited distal tibia fracture and loosened Schanz pins. click here CT angiogram revealed a pseudoaneurysm of the peroneal artery over the loosened pin site. The patient underwent exploration and ligation of the peroneal artery. Case report 02. 86-year-old female presented with a gradually enlarging lump on her left anteromedial thigh for three months duration. She underwent open reduction and internal fixation of ipsilateral femur fracture 17months back. She was found to have a pseudoaneurysm of the superficial femoral artery caused by exposed screws following bony erosion. Exploration and repair of "neck" the pseudoaneurysm was performed and the recovery was uneventful.

Pseudoaneurysms are rare but carry devastating complications following various orthopaedic procedures. The common cause for the formation of pseudoaneurysms is trauma during surgery. link2 But loosened Schanz screws and screws are also can be the cause. Early identification of a pseudoaneurysm and proper intervention will reduce morbidities.

Chronic, large, and old incisional hernias often lead to surgical complications and major hindrances during emergent laparotomies. The most challenging stages of the laparotomy in such cases occur during opening and fascial closure.

This article explains the novel surgical technique employed for the complex abdominal closure upon concluding an emergent laparotomy on a 68-year-old female patient. This innovative technique is appropriate for patients with contaminated abdominal cavities and scant fascia who require abdominal operations in cases where biological mesh is not available or is not a viable option.

This surgical technique can help surgeons restrict abdominal contents and organs (particularly the bowel loops) and prevent migration out of the abdominal cavity during the early post-operative stages, hence, reducing post-surgical complications. The discussed surgical technique ensures that the abdominal fascia defect is limited using skin flaps. This defect later develops into a small hernia sac within a few weeks. Patients then need to have a secondary delayed elective operation on this significantly smaller sized hernia for repair using synthetic mesh.

The use of chemical acaricides is still the most widely used control method despite its known disadvantages. Vaccination would be a safe alternative for the control of R. microplus and holds advantages over the use of chemical acaricides as it is environmental-friendly and leaves no residues in meat or milk. Two vaccines based on the Bm86 protein were commercialized, TickGARD® and Gavac®, with varying reported efficacies in different countries. The use of other vaccines, such as Tick Vac®, Go-Tick®, and Bovimune Ixovac® have been restricted to some countries. Several other proteins have been analyzed as possible antigens for more effective vaccines against R. microplus, including peptidases, serine proteinase inhibitors, glutathione S-transferases, metalloproteases, and ribosomal proteins, with efficacies ranging from 14% to 96%. Nonetheless, more research is needed to develop safe and efficient tick vaccines, such as the evaluation of the efficacy of antigens against other tick species to verify cross-reactivity and inclusion of additional antigens to promote the blocking of the infection and spreading of tick-borne diseases. This review summarizes the discoveries of candidate antigens for R. microplus tick vaccines as well as the methods used to test their efficacy.It is a major challenge to combine the advantages of two kinds of two-dimensional materials to construct a heterojunction and achieve efficient photocatalytic antifouling. In this work, we covalently connected two materials MXenes and covalent organic frameworks (COFs) through the Schiff base reaction and anchored Ag nanoparticles (NPs) to prepare a Ti3C2/TpPa-1/Ag composite material with high efficiency bactericidal properties. The covalent bonding between MXene and COF greatly improved the stability of the material. Ti3C2/TpPa-1/Ag composite showed an excellent antibacterial property against S. aureus and P. link3 aeruginosa. The fluorescence spectra of Ti3C2/TpPa-1/Ag proved that the electron transfer channels formed between the ternary materials could greatly improve the efficiency of carrier separation and prolong the life of photogenerated carriers. Density functional theory calculations showed that the synergistic catalytic effect of Ag and Ti3C2 could greatly reduce the work function along the interface, and the built-in electric field between the layers drive carrier fast migration, which effectively improve the catalytic performance.
Alkyltrimethoxysilane (ATMS) is among most widely used silane coupling agents. These commercially available, reasonably priced chemicals are often utilized to improve the compatibility of inorganic surfaces with organic coatings. With three hydrolysable moieties, ATMS is an outstanding candidate for solving the hydrophilicity, moisture sensitivity and high cost of silica aerogels. However, ATMS has a non-hydrolysable alkyl chain that undergoes cyclization reactions. The alkyl chain prevents ATMS from being incorporated in aerogel structures. Polyvinyltrimethoxysilane (PVTMS) is a silica precursor that offers two types of crosslinking to the final aerogel product. This strong doubly-crosslinked network can potentially suppress the cyclization reactions of ATMS and include it in aerogel structure.

PVTMS was used with ATMS having different alkyl lengths (3-16 carbons) and loadings (25 or 50wt%) as the silica precursors. Acid and base catalysts were used to perform hydrolysis and condensation reactions on the mixture and ATMSPVTMS aerogels were obtained via supercritical drying.
