Bacterial conjunctivitis is common and occurs in patients of all ages. Typical signs are a red eye and purulent drainage that persists throughout the day. ⋯ Bacterial conjunctivitis due to most other organisms can be treated empirically with topical antibiotics. Red flags suggesting a complicated case requiring referral to an ophthalmologist include reduced vision, severe eye pain, a hazy-appearing cornea, contact lens use, and poor response to empirical treatment.

Nowadays, doctors face an overwhelming amount of information, even in narrow areas of interest. In response, reviews designed to summarize the large volumes of information are frequently published. ⋯ A well-designed meta-analysis can provide valuable information for researchers, policymakers, and clinicians. However, there are many critical caveats in performing and interpreting them, and thus many ways in which meta-analyses can yield misleading information.

Chronic vitamin D deficiency, inadequate calcium intake, and secondary hyperparathyroidism are common in obese individuals, placing them at risk for low bone mass and metabolic bone disease. After bariatric surgery, they are at even higher risk, owing to malabsorption and decreased oral intake. Meticulous preoperative screening, judicious use of vitamin and mineral supplements, addressing modifiable risk factors, and monitoring the absorption of key nutrients postoperatively are essential in preventing metabolic bone disease in bariatric surgery patients.

Review Case Reports
Prevention of venous thromboembolism in the hospitalized medical patient.
Hospitalized acutely ill medical patients are at high risk for venous thromboembolism (VTE), and clinical trials clearly demonstrate that pharmacologic prophylaxis of VTE for up to 14 days significantly reduces the incidence of VTE in this population. Guidelines recommend use of low-molecular-weight heparin (LMWH) or unfractionated heparin (5,000 U three times daily) for VTE prophylaxis in hospitalized medical patients with risk factors for VTE; in patients with contraindications to anticoagulants, mechanical prophylaxis is recommended. All hospitalized medical patients should be assessed for their risk of VTE at admission and daily thereafter, and those with reduced mobility and one or more other VTE risk factors are candidates for aggressive VTE prophylaxis. Based on results from the recently reported EXCLAIM trial, extended postdischarge prophylaxis with LMWH for 28 days should be considered for hospitalized medical patients with reduced mobility who are older than age 75 or have a cancer diagnosis or a history of VTE.

Patients undergoing major orthopedic surgery--hip or knee arthroplasty, or hip fracture repair--are in the highest risk category for venous thromboembolism (VTE) solely on the basis of the orthopedic procedure itself. Despite this, nearly half of patients undergoing these procedures do not receive appropriate prophylaxis against VTE, often due to a disproportionate fear of bleeding complications in this population. Guidelines from the American College of Chest Physicians (ACCP) provide evidence-based recommendations for many aspects of VTE risk reduction in the setting of orthopedic surgery, as detailed in this review. ⋯ Fondaparinux is the preferred recommendation for patients undergoing hip fracture repair, followed by LMWH, unfractionated heparin, and adjusted-dose warfarin as alternative options. Extended-duration prophylaxis (for 4 to 5 weeks) is now recommended for patients undergoing hip arthroplasty or hip fracture repair. Patients undergoing knee arthroscopy do not require routine pharmacologic VTE prophylaxis.
