BACKGROUND: Page kidney phenomenon is caused by strong renal parenchymal compression and leads to renal hypoperfusion and microvascular ischemia, resulting in renal dysfunction and hypertension. Although the development of Page kidney phenomenon in allograft is rare, most of its cases are induced by allograft biopsy or trauma. We observed a case of Page kidney phenomenon that was induced by unusual causes immediately after kidney transplantation. CASE PRESENTATION: A 66-year-old man, whose wife donated a kidney, underwent ABO-compatible living kidney transplantation...

BACKGROUND: Neurofibromatosis type 2 (NF2) is a genetic condition with an autosomal dominant pattern of inheritance and incomplete penetrance. It is characterized by multiple benign tumors of the central and peripheral nervous system including astrocytomas, ependymomas, meningeomas, and schwannomas, among which bilateral vestibular schwannomas are the most frequent. Among ocular manifestations of NF2, juvenile subcapsular cataract is the most common followed by epiretinal membranes and combined hamartomas of the retina and retinal pigment epithelium...

Cataract formation in the posterior subcapsular region of the lens is a lesion highly specific to both high-dose acute radiation exposure and chronic low-dose exposure. Low-dose radiation may not manifest lens changes for several decades after initial exposure. Cardiac catheterization team members need to be educated on, and protected from, this form of radiation injury as its long latency period between exposure and physical damage may acutely reduce the sense of hazard amongst healthcare radiation workers...

Human pluripotent stem cell (hPSC)-derived kidney organoids may facilitate disease modeling and the generation of tissue for renal replacement. Long-term application, however, will require transferability between hPSC lines and significant improvements in organ maturation. A key question is whether time or a patent vasculature is required for ongoing morphogenesis. Here, we show that hPSC-derived kidney organoids, derived in fully defined medium conditions and in the absence of any exogenous vascular endothelial growth factor, develop host-derived vascularization...

RATIONALE: Hemorrhage, one of complications after liver biopsy, is often identified immediately after the procedure while delayed liver rupture is relatively rare. PATIENT CONCERNS: A 45-year-old woman was diagnosed with undetermined liver cirrhosis and abnormal liver function. To determine the etiology and severity of liver cirrhosis, ultrasound-guided liver biopsy was arranged. The patients did not complain any pain during the procedure. Ultrasound examination on postoperative day1 (POD 1) and MRI on POD 3 showed no evidence of hematoma and ascites...

Isolated hepatic arteries are defined as hepatic terminal arterioles that are not accompanied by portal venules or bile ductules and penetrate the liver parenchyma and distribute to the hepatic capsule and intrahepatic hepatic veins. Abundant communications exist between intra- and extrahepatic arteries through isolated arteries and capsular arterial plexus. They play a principal role in the development of subcapsular hemorrhage and arterial collateral formation following transcatheter arterial chemoembolization for liver cancers...

INTRODUCTION: Radiofrequency ablation (RFA) is an effective and minimally invasive technique for the management of hepatic hemangiomas (HHs). This study aims to assess the safety and efficacy of laparoscopic RFA for HHs. MATERIAL AND METHODS: Forty-four patients with 50 hepatic hemangiomas (5-10 cm in diameter) undergoing laparoscopic RFA from January 2012 to May 2015 at three tertiary hospitals in China were retrospectively analyzed. RESULTS: Thirty-three patients with subcapsular hemangiomas were treated with a laparoscopic approach, and 11 patients with lesions in the liver parenchyma were treated with a combined laparoscopy and an ultrasound-guided percutaneous approach...

Purpose: To image, describe, and characterize different features visible in the crystalline lens of older adults with and without cataract when imaged three-dimensionally with a swept-source optical coherence tomography (SS-OCT) system. Methods: We used a new SS-OCT laboratory prototype designed to enhance the visualization of the crystalline lens and imaged the entire anterior segment of both eyes in two groups of participants: patients scheduled to undergo cataract surgery, n = 17, age range 36 to 91 years old, and volunteers without visual complains, n = 14, age range 20 to 81 years old...

INTRODUCTION AND OBJECTIVES: Percutaneous nephrolithotomy remains a challenging procedure primarily due to difficulties obtaining access. Indeed, few urologists obtain their own access due to difficulties using a fluoroscopic or ultrasonic based antegrade puncture technique. Herein we report the first experience using holmium laser energy to obtain access in a retrograde fashion. METHODS: After a pretreatment week of tamsulosin 0.4 mg/day (one center only) and following a documented sterile urine, a total of ten patients underwent retrograde holmium laser-assisted endoscopic-guided nephrostomy access in a prone split leg position...

Splenic injury is a rare but serious complication of bariatric surgical procedures. Given that the need for dissection of the gastrosplenic ligament during bariatric surgical procedures, splenic injury is not unfathomable. While most subcapsular splenic hematomas may be self-limiting, continued expansion may result in splenic rupture and should, therefore, be handled with great care. With the growing rate of bariatric surgical procedures worldwide, inadvertent intra-operative splenic injury may become a more prevalent surgical complication...

Staphylococcus aureus is a skin- and respiratory tract-colonizing bacterium and is the leading cause of community-acquired skin infections. Dissemination of these bacteria into systemic circulation causes bacteremia, which has a high mortality rate. Therefore, understanding the immunologic barriers that prevent dissemination is critical to developing novel treatments. In this study, we demonstrate that an S. aureus breach across skin leads to some migration of the pathogen to the draining lymph node, but no further...

AIM: To evaluate the efficacy of a technical modification to reduce the incidence of traumatic cataract induced by Descemet stripping automated endothelial keratoplasty (DSAEK) performed in phakic eyes. METHODS: A retrospective cohort study. The records of all patients with a clear crystalline lens and endothelial failure that underwent modified DSAEK at our insitution were reviewed. In this modification, in order to avoid inadvertent touch of the insertion forceps against the exposed crystalline lens while passing across the anterior chamber, the incision sites were shifted from the standard 9 and 3 o'clock positions, superiorly to the 10 and 2 o'clock position respectively...

BACKGROUND: Saving the parathyroid gland during thyroidectomy remains challenging. Subcapsular saline injection (SCASI) was developed in February 2015. Its ability to spare the parathyroid gland was assessed. METHODS: All consecutive patients who underwent total thyroidectomy with or without neck lymph node dissection in 2013-2015 were included in this retrospective cohort study. Patients were divided into the SCASI and non-SCASI groups. Serum parathyroid hormone (PTH) levels were measured on day 1 and 6 months after surgery...
