BACKGROUND: Sigmoid resection in diverticulitis is one of the most frequently performed colonic operations. A minimally invasive approach by laparoscopy is the surgical gold standard. For a few years now, sigmoid resections have also been performed robotically (da Vinci® System). It is unclear whether there are relevant differences between the two procedures in terms of functional outcome. METHODS: A postoperative follow-up was performed on all patients who underwent laparoscopic or robotic sigmoid resection for diverticulitis between November 2013 and November 2018, with a minimum interval of 6 months between surgery...

The mechanism by which nitric oxide synthase (NOS) inhibition impacts human sweating is unknow. We tested the hypothesis that the activation of NOS and release on nitric oxide acts to open K+ channels and enhance sweat gland output. Local sweat rate (SR) was measured with a small sweat capsule mounted on the skin while sweating was initiated by intradermal electrical stimulation. Sigmoid shape stimulus-response curves were generated by plotting the area under the SR-time curve versus log10 stimulus frequency and normalized to the peak response during control trials...

BACKGROUND: A significant proportion of spontaneous cerebrospinal fluid (sCSF) leaks are associated with idiopathic intracranial hypertension (IIH). The aim of this study was to assess the association between sCSF rhinorrhea and transverse venous sinus stenosis (VSS), a feature commonly observed in IIH with a proposed role in its pathophysiology. METHODS: In this single-center, retrospective, matched case-control study, venous and pituitary imaging data of consecutive patients undergoing endoscopic surgery for sCSF rhinorrhea over the last 10 years were retrospectively reviewed...

This work describes the construction and evaluation of carbon fiber ultramicroelectrodes (CF-UMEs) in the voltammetric estimation of the antioxidant capacity of wine and grape samples based on caffeic acid (HCAF) oxidation. For this, lab-made CF-UMEs were constructed using an arrangement of six carbon fibers (7 μm diameters individual) assembled in a glass capillary, and caffeic acid (HCAF) was used as a standard solution. By using the most straightforward 2-electrode cell arrangement (the CF-UME as a working electrode and Ag/AgCl as a reference/auxiliary electrode), voltammetric measurements of a 1...

We provide a unique case of report of fibromation of small intestinal ligament in a patient with sigmoid colon cancer. This is the first case that one patient suffered these two kinds of tumor, as far as we know, there is no such case before. Due to his medical history of malignant cancer, so the fibromation of small intestinal ligament was suspected to be a metastatic lesion when it was found by radiologists, so operation had been performed. Finally, it was confirmed by pathological result. After the operation and postoperative chemotherapy, the two masses were removed and the patient had no significant complications, during follow-up, the patient is gradually recovering...

OBJECTIVE: Identify clinical and radiographic features of venous infarct as a presenting feature of COVID-19 in the young. BACKGROUND: SARS-CoV-2 infection causes hypercoagulability and inflammation leading to venous thrombotic events (VTE). Although elderly patients with comorbidities are at higher risk, COVID-19 may also cause VTE in a broader patient population without these risks. Neurologic complications and manifestations of COVID-19, including neuropathies, seizures, strokes and encephalopathy usually occur in severe established cases of COVID-19 infection who primarily present with respiratory distress...
