Vitamin D Supplementation for Patients with Dry Eye Syndrome Refractory to Conventional Treatment.

This study investigated the effect of vitamin D supplementation in patients with dry eye syndrome (DES) refractory to conventional treatment with vitamin D deficiency. A total of 105 patients with DES refractory to conventional treatment and vitamin D deficiency that was treated with an intramuscular injection of cholecalciferol (200,000 IU). Serum 25-hydroxyvitamin D (25(OH)D) levels were measured.

Low Serum 25-Hydroxyvitamin D Levels Are Associated with Dry Eye Syndrome.

Background: Dry eye syndrome (DES) is a common tear film and ocular surface disease that results in discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. Systemic diseases associated with DES include diabetes mellitus, rheumatoid arthritis, depression, anxiety, thyroid disease, allergic diseases, irritable bowel syndrome, chronic pain syndrome, and hyperlipidemia. Interestingly, it has been found that most of these are associated with low levels of serum 25-hydroxyvitamin D (25(OH)D) or inadequate sunlight exposure.

Delayed flumazenil injection after endoscopic sedation increases patient satisfaction compared with immediate flumazenil injection.

Background/aims: Flumazenil was administered after the completion of endoscopy under sedation to reduce recovery time and increase patient safety. We evaluated patient satisfaction after endoscopy under sedation according to the timing of a postprocedural flumazenil injection.

Methods: In total, 200 subjects undergoing concurrent colonoscopy and upper endoscopy while sedated with midazolam and meperidine were enrolled in our investigation.

Risk factors for long-term outcomes after initial treatment in hepatolithiasis.

Hepatobiliary complications, such as stone recurrence, recurrent cholangitis, liver abscess, secondary biliary cirrhosis, and cholangiocarcinoma may occur after treatment for hepatolithiasis. However, few previous studies have addressed the risk factors and long-term outcomes after initial treatment. Eighty-five patients with newly diagnosed hepatolithiasis, actively treated for hepatolithiasis, constituted the cohort of this retrospective study.

Subcontractors and increased risk for work-related diseases and absenteeism.

Background: Despite increasing reliance on subcontracting in many economic sectors, there is little information available on occupational health and safety issues among subcontractor employees. The purpose of this study was to investigate the effect of subcontracting on self-reported health problems and absences due to occupational accidents and sickness using a nationally representative sample from South Korea.

Methods: The data used were sampled from the second wave of the Korean Working Conditions Survey [2010].

Is endoscopic ultrasound needed as an add-on test for gallstone diseases without choledocholithiasis on multidetector computed tomography?

Background: Choledocholithiasis commonly occurs in patients with symptomatic cholelithiasis. Although the recently developed multidetector computed tomography (MDCT) scan enhances the ability to diagnose choledocholithiasis, this technique is considered to have some limitations for evaluating the common bile duct (CBD).

Aim: The purpose of this study was to evaluate the necessity for performing endoscopic ultrasound (EUS) as an add-on test to detect choledocholithiasis in patients who were diagnosed with gallstone disease without choledocholithiasis based on MDCT.

Does the bile duct angulation affect recurrence of choledocholithiasis?

Aim: To investigate whether bile duct angulation and T-tube choledochostomy influence the recurrence of choledocholithiasis.

Methods: We conducted a retrospective study inclu-ding 259 patients who underwent endoscopic sphincterotomy and cholecystectomy for choledocholithiasis between 2000 and 2007. The imaginary line was drawn along the center of the bile duct and each internal angle was measured at the two angulation sites of the bile duct respectively.

Plasma Total Homocysteine Levels are not Associated with Medial Temporal Lobe Atrophy, but with White Matter Changes in Alzheimer's Disease.
