The aim of this study was to identify the effect of different injection times on pain during colonoscopy procedure.

Primary intracranial synovial sarcomas (PrISS) are unusual dural based mesenchymal tumors seen most commonly in the supratentorial compartment. They can mimic a spontaneous intracranial hemorrhage or a high-grade glioma on imaging.

Systemic autoantibodies are important for the diagnosis of autoimmune diseases, but their roles in anti–methyl-D-aspartate receptor (anti-NMDAR) encephalitis are unknown. The purpose of our study is to investigate the characteristics and a prognosis of anti-NMDAR encephalitis with the prevalence of autoantibodies.

Patients with dysphagia often have an esophageal disorder. This case report describes a patient with persistent dysphagia and chest pain who had a normal esophagogastroduodenoscopy. Computed tomography of the chest with contrast revealed an aberrant right subclavian artery compressing the esophagus. A vascular procedure was performed and corrected the dysphagia. This case demonstrates that aberrant vessels can occasionally cause dysphagia.

A 22-year-old woman presented with a 12-year history of intensifying paroxysms of anxiety, palpitations and recurrent syncope following micturition. The patient was referred to endocrinology upon discovery of hypertension. An extended family history revealed metastatic phaeochromocytoma and paraganglioma in two grand-uncles. Clinical examination revealed hypertension, with a mean 24-hour ambulatory blood pressure of 150/100 mmHg. Supine plasma normetanephrines were markedly elevated with a raised 3-methoxytyramine, while plasma metanephrines were normal. Computed tomography identified a 4.4 cm mass at the right inferolateral margin of the bladder wall. Scintigraphic imaging confirmed unifocal bladder lesion uptake with no additional metastatic lesions. Following pre-operative alpha blockade, the patient underwent a partial cystectomy. Histology confirmed a paraganglioma, and SDHB staining was lost in neoplastic cells consistent with an SDHB-related paraganglioma. Plasma normetanephrine, 3-methoxytyramine and blood pressure returned to normal postoperatively. Genetic screening identified a germline heterozygous SDHB gene variant c.723C>G. Bladder paragangliomas are a rare but important differential to consider when investigating post-micturition syncope. An extended family history should be sought and suspicion for a genetic cause should be raised, especially when the condition presents at a young age. This is the first reported case describing phaeochromocytoma or paraganglioma with the SDHB gene variant c.723C>G.

Propofol combined with remifentanil is the most common anesthesia method in laparoscopic hysteromyomectomy. However, whether the combination of the two is helpful to patients undergoing hysteromyomectomy still requires unclear.

Congenital peritoneal encapsulation is a rare entity characterized by an accessory peritoneal membrane that forms during embryonic development. Congenital peritoneal encapsulation is generally asymptomatic but can cause intermittent, colicky abdominal pain related to subacute small bowel obstruction. Diagnosis is made incidentally or upon surgical exploration for chronic abdominal complaints as preoperative imaging is typically nonspecific. We report a case of a 49-year-old male with epigastric abdominal pain, constipation, and superior mesenteric vein thrombosis on imaging. Upon exploratory laparotomy, the small bowel was covered by an accessory peritoneal sac consistent with congenital peritoneal encapsulation. The accessory sac was excised completely, and the patient recovered well. Although rarely causing significant gastrointestinal symptoms, congenital peritoneal encapsulation is an anomaly that requires surgical intervention.

Erector spinae plane block (ESPB) has been used for many thoracic and abdominal surgeries. However, evidence of its analgesic efficacy following abdominal surgery, compared with that of thoracic analgesia, is insufficient. Our study explored the analgesic effect of ESPB after abdominal surgery.

The efficacy and adverse reactions of remimazolam besylate (RB) in combination with alfentanil in patients with painless gastroscopy remain unclear.

The aim of this study was to evaluate the standard values for gender- and age-stratified serum pepsinogen (sPG) in Helicobacter pylori (H. pylori) non-infected children and to determine the optimal cut-off values of sPG for predicting H. pylori-infected gastritis in children.
