This study aimed to characterize the expression status and potentially mechanistic involvement of SNHG7 in pituitary adenoma. Relative expression of SNHG7 and miR-449a was analyzed by real-time PCR. Cell viability was measured with Cell Counting Kit-8 (CCK-8). Cell apoptosis was determined by PI/Annexin V double staining followed by flow cytometry analysis. Cell invasion and migration were analyzed by wound healing and transwell assays, respectively. The regulatory action of miR-449a on SNHG7 was interrogated by luciferase reporter assay. We also investigated the pro-tumor activity of SNHG7 with the MMQ xenograft tumor mouse model. We identified the aberrant up-regulation of SNHG7 in pituitary adenoma both in vivo and in vitro, which associated with poor survival outcome. siRNA-mediated SNHG7-knockdown decreased cell viability, increased apoptosis and compromised migration and invasion. We further predicted and validated that SNHG7 negatively regulated miR-449a via sponging. Concurrent inhibition of miR-449a restored cell viability, apoptosis, migration and invasion influenced by SNHG7-deficiency. Belvarafenib inhibitor Most importantly, we demonstrated that SNHG7-silencing delayed xenograft tumor progression, which was accompanied with increased miR-449a and decreased Ki67 intensity. Our study highlighted the essential oncogenic properties of the SNHG7/miR-449a axis in pituitary adenoma.Mesalazine formulations are essential for treating ulcerative colitis (UC), and intolerance to these formulations complicates the treatment of this condition. Some cases of mesalazine formulation intolerance are caused by the excipients rather than the active ingredient mesalazine. Therefore, mesalazine administration can be continued in such cases by changing the mesalazine formulation. This report describes a case of intolerance to mesalazine in which UC was effectively treated by switching mesalazine formulations. A drug-induced lymphocyte stimulation test suggested that allergy to the additive povidone was the cause of mesalazine formulation intolerance. This is the first case study to identify an additive that caused mesalazine formulation intolerance.Serous neoplasms (SNs) of the pancreas are usually considered benign tumors. However, they rarely manifest malignant behaviors. Here we present a case of malignant SN and review the literature of malignant SN. A 71-year-old woman presented to our hospital with a palpable abdominal mass. Imaging studies revealed a 7 cm mass with a cluster of microcysts having a honeycomb appearance in the head of the pancreas, which invaded the superior mesenteric vein (SMV). After being clinically diagnosed with SN, pancreaticoduodenectomy was performed with resection of limited SMV. Microscopically, the tumor was diagnosed as an SN concomitant with the tumor thrombus in the SMV. Four years after the surgery, two liver tumors and two peritoneal nodules were detected and three of them were surgically resected. All of those lesions had a honeycomb appearance in their cut surfaces and they were microscopically indistinguishable from the originally resected SN. A review of the literature identified 22 cases of malignant metastatic SNs published to date. Even though extremely rare, metachronous metastasis could occur in SNs of the pancreas. Local invasion indicated an increased likelihood of future metastasis. Thus, periodic surveillance should be considered for SNs after resection, especially when they have a local invasion.Melanoma presenting in the gastrointestinal tract is commonly due to metastasis from a primary cutaneous or ocular lesion. There have been a few case reports of primary GI melanoma which is commonly seen in the rectum and anus. We report a case of a 77-year-old man who presented with GI bleeding and was found to have a primary small bowel melanoma. This case highlights how to approach the workup of a melanoma lesion found in the GI tract.Although migraine is generally considered an idiopathic and isolated neurological condition, it may also represent the presenting symptom of several uncommon heritable and acquired neurological diseases contributing to the recognition of such conditions. Migraine may indeed present with atypical characteristics or prolonged duration and may be associated with specific neuroradiological findings that may help in identifying the underlying condition. However, features of migraine in rare diseases are usually little known because of the lack of systematic studies. The aim of this paper is to provide clinicians with an updated review on specific clinical and neuroradiological features of migraine in uncommon neurological diseases that may be helpful to their diagnosis and treatment. Therefore, the early diagnosis of these uncommon diseases is crucial for patients' clinical management and for the implementation of therapeutic approaches aimed at targeting the underlying disease pathogenic mechanisms. Thus, when investigating patients affected by migraine, physicians should always be aware about rare causes of migraine that if misdiagnosed could seriously impact patients' outcome. Given these relevant implications, future studies specifically assessing features of migraine in uncommon diseases are mandatory.

Adaptive servo-ventilation (ASV) is a therapy designed for patients with central sleep apnea (CSA) and Cheyne Stokes respiration. The aim of this study was to find predictors of ASV usage in patients with CSA in a routine sleep clinic cohort.

In this retrospective study, consecutive patients in whom ASV therapy was initiated at the University Hospital Regensburg between 2011 and 2015, were analyzed. Analysis included polysomnographies of diagnostic and ASV initiation nights, a phone questionnaire on ASV usage, readout of the ASV device 1 month after initiation ("early ASV usage," 1 month after ASV initiation), and the readout of the last month before a reappointment date set in 2015 ("late ASV usage," median 17 months after ASV initiation).

In 69 consecutive patients, the mean early and late ASV usage per night was 4.8 ± 2.5 h and 4.1 ± 3.0 h, respectively. Seventeen months after initiation, 57% of patients used the device ≥ 4 h per night, andof those 91% reported a subjective benefit from ASV therapy. Early ASV usage was significantly associated with late ASV usage (univariable regression Beta 0.
