Observational Study
Risk factors for postoperative complications in total thyroidectomy: A retrospective, risk-adjusted analysis from the National Surgical Quality Improvement Program.
Thyroid cancer incidence is increasing, and with it, an increase in total thyroidectomy. There are limited studies comparing outcomes in total thyroidectomy performed in the inpatient versus outpatient setting. The objective of this study was to perform a comparative analysis of risk factors and outcomes of postoperative morbidity and mortality in total thyroidectomy performed as an inpatient versus outpatient surgery. ⋯ In addition, preoperative factors affecting complications in thyroidectomy performed as an outpatient surgery included malignant thyroid pathology (P 0.05). We identified a subset of preoperative conditions that affect risk of complications after total thyroidectomy. Recommendations for patient selection for outpatient total thyroidectomies should be modified to account for pre-existing conditions that increase the risk of postoperative morbidity.

Observational Study
Incidence and risk factors of acute kidney injury associated with continuous intravenous high-dose vancomycin in critically ill patients: A retrospective cohort study.
For vancomycin therapy of severe infections, the Infectious Diseases Society of America recommends high vancomycin trough levels, whose potential for inducing nephrotoxicity is controversial. We evaluated the incidence and risk factors of acute kidney injury (AKI) in critically ill patients given continuous intravenous vancomycin with target serum vancomycin levels of 20 to 30 mg/L. We retrospectively studied 107 continuous intravenous vancomycin treatments of ≥48 hours' duration with at least 2 serum vancomycin levels ≥20 mg/L in critically ill patients. ⋯ Factors independently associated with AKI were highest serum vancomycin ≥40 mg/L (odds ratio [OR], 3.75; 95% confidence interval [CI], 1.40-10.37; P < 0.01), higher cumulative number of organ failures (OR, 2.63 95%CI, 1.42-5.31; P < 0.01), and cirrhosis of the liver (OR, 5.58; 95%CI, 1.08-31.59; P = 0.04). In this study, 29% of critically ill patients had AKI develop during continuous intravenous vancomycin therapy targeting serum levels of 20 to 30 mg/L. Serum vancomycin level ≥40 mg/L was independently associated with AKI.

Observational Study
Shifting trends in microbial keratitis following penetrating keratoplasty in Taiwan.
To investigate the clinical and microbiological profiles from microbial keratitis following penetrating keratoplasty (PKP) in a tertiary referral center in Taiwan, the medical records of 648 consecutive patients (648 eyes) undergoing PKP between January 2003 and December 2007 were retrospectively reviewed. Patients who subsequently sustained microbial keratitis were enrolled and analyzed for potential risk factors, clinical manifestations, microbiological profiles, complications, graft survival, and final visual outcome. A total number of 42 corneal graft infections (6.5%) were recruited. ⋯ In conclusion, microbial keratitis following PKP is a devastating event that severely impairs graft survival rate and postoperative visual outcome which usually occur within the first postoperative year. The incidence of post-PKP microbial keratitis has generally decreased in recent years whilst P. aeroginosa prevails as the leading cause of graft infection in our hospital. Close follow-up by ophthalmologists and elevated self-awareness of patients for at least one year are always encouraged to prevent late-onset infection.

Case Reports
A case report of posterior reversible encephalopathy syndrome in a patient receiving gemcitabine and cisplatin.
Posterior reversible encephalopathy syndrome (PRES) is a subacute syndrome causing characteristic neurologic and radiologic findings. PRES is predominantly caused by malignant hypertension though it has been associated with immunosuppressive treatments such as chemotherapy. ⋯ Cisplatin is a documented causative agent of PRES though gemcitabine is rarely associated with the syndrome. Combination cisplatin and gemcitabine therapy causing radiologically proven PRES has been documented in only 3 previous case reports. Gemcitabine's poor blood-brain barrier penetration makes it an unlikely culprit of central nervous system (CNS) toxicities. Our case and previous reports suggest higher doses may contribute to CNS toxicities such as PRES. Additionally, an emerging trend of hypomagnesemia associated with PRES has been documented inside and outside the context of malignancy and suggests a possible target for treatment and prevention warranting further investigation.

Cystatin-C is associated with partial recovery of kidney function and progression to chronic kidney disease in living kidney donors: Observational study.
Donor nephrectomy in living-donor kidney transplantation may result in hyperfiltration injury in remnant kidney; however, its clinical implication in partial recovery of kidney function (PRKF) in remnant kidney and chronic kidney disease (CKD) progression remains unclear. Thus, we investigated the effect of PRKF on CKD development in the residual kidney and the utility of cystatin-C (Cys-C) in evaluating renal function in living-donor kidney transplantation donors. The electronic medical records and laboratory results of 1648 kidney transplant (KT) donors and 13,834 healthy nondonors between January 2006 and November 2014 were reviewed. ⋯ After PSM, the risk of progression to CKD was higher in KT donors than in healthy nondonors (HR, 58.4; 95% CI, 34.2-99.8; P < 0.001). Donor nephrectomy is associated with PRKF and progression to CKD. Cys-C is a useful early marker for detecting PRKF and CKD.
