We report a case of idiopathic paracentral acute middle maculopathy with typical optical imaging and clinical features. A 26-year-old Chinese policeman presented with a 20-day history of paracentral scotoma in the left eye after early wake-up and long-time working in front of computer the day before. He experienced sudden-onset strong flash in his left eye. Paracentral scotoma appeared in his left eye after 6hours of rest. The general history was negative. His best-corrected visual acuity was 20/20 OU. Anterior segment, dilated fundus examination, papillary evaluation and intraocular pressure were normal...

REVIEW
Ryan C Owen, Benjamin J McCormick, Bradley D Figler, Robert M Coward
A dilation of the pampiniform venous plexus in the scrotum above the testicle, called a varicocele, affects approximately 15% of the general male population. While the majority is asymptomatic, pain results in up to 10% of cases of varicoceles. The pain associated with varicoceles is typically mild and is described as heavy, achy, or dull-and is usually isolated to the testicle or spermatic cord. Guidelines clearly recommend varicocele repair in males with varicoceles, infertility, and an abnormal semen analysis...

BACKGROUND AND OBJECTIVES: This dose-finding study aimed to determine the minimum effective volume in 90% of patients (MEV90) of lidocaine 1.5% with epinephrine 5 μg/mL for ultrasound-guided costoclavicular block. METHODS: Using an in-plane technique and a lateral-to-medial direction, the block needle was positioned in the middle of the 3 cords of the brachial plexus in the costoclavicular space. The entire volume of lidocaine was deposited in this location. Dose assignment was carried out using a biased-coin-design up-and-down sequential method, where the total volume of local anesthetic administered to each patient depended on the response of the previous one...

The activity of the hypothalamo-pituitary gonadal (HPG) axis is influenced by energy reserves, such that an increase or a decrease in adiposity may perturb the secretion and action of GnRH. This is thought to be due to the signalling of hormones such as leptin, which act upon neuronal systems controlling GnRH secretion. Other work shows plasticity in the relationship between tanycytes and GnRH neurosecretory terminals in the median eminence across the estrous cycle and we hypothesised that similar plasticity may occur with altered metabolic status...

Zhanlong Shen, Yingjiang Ye, Shan Wang
Total mesorectal excision (TME) is a mile-stone procedure in the history of rectal cancer surgery, but the exposure of surgical field of distal rectum is usually poor in patients with male, obese and narrow pelvis, which may lead to tumor residue and relative complications. Recently, a new technique called transanal TME (taTME) is considered to solve the above problems, but most medical centers are still in the learning curve of this procedure. Therefore, anatomical planes and landmarks of taTME for rectal cancer and prophylaxis of intraoperative complications are induced in this paper, which includes posterior plane: angle of anus and distal mesorectum and bleeding of mesorectum; rectosacral fascia and presacral bleeding; lateral and posterior-lateral plane: posterior branches of pelvic plexus and damage of anal function; anterior plane: vessel branches of neurovascular bundle and bleeding...

PURPOSE: Arthroscopic shoulder surgery can be performed with an interscalene brachial plexus block (ISBPB) alone, ISBPB combined with general anesthesia (GA), or GA alone. Postoperative pain is typically managed with opioids; however, both GA and opioids have adverse effects which can delay discharge. This retrospective study compares the efficacy of four methods of anesthesia management for arthroscopic shoulder surgery. METHODS: Charts of all patients who underwent shoulder surgery by a single surgeon from 2012-2015 were categorized by analgesic regimen: GA only (n = 177), single-shot ISBPB only (n = 124), or pre- vs postoperative ISBPB combined with GA (ISBPB + GA [n = 72] vs GA + ISBPB [n = 52], respectively)...

BACKGROUND: Obstetrical brachial plexus palsy can lead to fixed forearm supination contracture. Fixed supination may lead to functional deficits as the affected hand cannot be positioned optimally for activities on a desk such as writing and typing, or for using tools including utensils, which require a neutral or pronated forearm. Forearm pronation osteotomy has been used to address this problem, although the functional benefit over nonoperative management has not been clearly defined...

INTRODUCTION: Two main hypotheses have been proposed for the pathophysiology of long thoracic nerve (LTN) palsy: nerve compression and nerve inflammation. We hypothesized that critical reinterpretation of electrodiagnostic (EDX) studies and MRIs of patients with a diagnosis of non-traumatic isolated LTN palsy could provide insight into the pathophysiology and, potentially, the treatment. MATERIAL AND METHODS: A retrospective review was performed of all patients with a diagnosis of non-traumatic isolated LTN palsy and an EDX and brachial plexus or shoulder MRI studies performed at our institution...

Angiogenic sprouting needs to be tightly controlled. It has been suggested that the Notch ligand dll4 expressed in leading tip cells restricts angiogenesis by activating Notch signalling in trailing stalk cells. Here, we show using live imaging in zebrafish that activation of Notch signalling is rather required in tip cells. Notch activation initially triggers expression of the chemokine receptor cxcr4a. This allows for proper tip cell migration and connection to the pre-existing arterial circulation, ultimately establishing functional arterial-venous blood flow patterns...

BACKGROUND: Short-chain fatty acids (SCFA) are microbial fermentation products absorbed by the colon. We recently reported that activation of the SCFA receptor termed free fatty acid receptor 3 (FFA3), expressed on cholinergic nerves, suppresses nicotinic acetylcholine receptor (nAChR)-mediated transepithelial anion secretion. This study aimed to clarify how activation of neurally expressed FFA3 affects colonic motor function. METHODS: FFA3-expressing myenteric neurons were identified by immunostaining; contractions of isolated circular muscle strips obtained from rat proximal colon were measured by isometric transducers...
