BACKGROUND: The gradually increasing demand for coffee worldwide has prompted increased interest in the relationship between coffee and health issues as well as a need for research on metabolic syndrome in adults. METHODS: Data from 3,321 subjects (1,268 men and 2,053 women) enrolled in the 2013–2014 Korean National Health and Nutrition Examination Survey were analyzed. The subjects were divided into three groups according to their daily coffee consumption. The odds ratios (ORs) and 95% confidence intervals (95% CIs) for metabolic syndrome in the coffee-drinking groups were calculated using multiple logistic regression analysis by adjusting for confounding variables. RESULTS: The prevalence of metabolic syndrome was 15.5%, 10.7%, and 9.7% in men and 3.0%, 7.1%, and 6.5% in women according to their coffee consumption (less than one, one or two, or more than three cups of coffee per day), respectively. Compared with the non-coffee consumption group, the ORs (95% CIs) for metabolic syndrome in the group that consumed more than three cups of coffee was 0.638 (0.328–1.244) for men and 1.344 (0.627–2.881) for women after adjusting for age, body mass index, household income, education, smoking, alcohol, regular exercise, and daily caloric intake. CONCLUSION: The OR of metabolic syndrome was not statistically significant in both men and women.

A 16-year-old Korean male patient presented with macrodactyly, hemihypertrophy of the face and extremities, plantar cerebriform hyperplasia, a subcutaneous mass of the left chest, macrocephaly and verrucous epidermal nevi. These findings are consistent with Proteus Syndrome. The clinical features, etiology, management, natural course and differential diagnosis of this case are discussed.

PURPOSE: Soft tissue reconstruction of a defect around the foot and ankle is a particularly challenging procedure due to the anatomical and functional characteristics of this area. Hence, only a limited number of treatment options are available. Moreover, if patients wish to avoid additional scars on the ipsilateral lower leg for cosmetic reasons, even fewer options are available for treatment. The authors used an anterolateral thigh perforator flap for soft tissue defects in this area, when other surgical options were inadequate. The aim of this study was to report the clinical results and the efficacy of this procedure. MATERIALS AND METHODS: Sixteen cases of soft tissue defects around the foot and ankle were included. Participants included 12 male and 4 female subjects, and the mean age was 34 years. The most common cause of defect was acute trauma, and the average follow-up period was 33 months. Flap survival time, surgical complications, and ambulation status at the final follow-up stage were evaluated. RESULTS: All 16 flaps successfully survived, except for one case with partial flap necrosis that was thought to be due to weight bearing earlier than scheduled. All patients were able to walk independently without any aid at the final follow-up stage. No patients showed other significant surgical complications. CONCLUSION: The anterolateral thigh perforator flap is a good alternative for soft tissue defects of the foot and ankle, when other options are not applicable. This study also demonstrated that surgery using an anterolateral thigh perforator flap is safe and highly reliable.

Atherectomy has become a promising treatment option for peripheral artery disease caused by diabetes mellitus or end-stage renal disease. Atherectomy refers to the removal of atheromatous tissue by mechanical method, resulting in an enlarged lumen of the treated blood vessel. Based on this method, the term is limited to the percutaneous minimally invasive approach, and there are currently two types of atherectomy devices available in Korea. The increased prevalence of atherectomy has led to the concept of “vascular preparation” and a new treatment concept of “leave nothing behind.” Various studies have proven the safety and effectiveness of atherectomy; however, there are some limitations. We need to remain focused on patient selection and subsequent large-scale research.

PURPOSE:
To evaluate the clinical efficacy and safety of uterine artery embolization (UAE) using N-butyl-2-cyanoacrylate (NBCA) in patients with postpartum hemorrhage (PPH).
MATERIALS AND METHODS:
From February 2010 to May 2018, 14 patients (age: 28–39 years; mean: 33 years) underwent UAE using NBCA among 82 patients with PPH. Medical records were retrospectively reviewed to evaluate the patients characteristics, cause of PPH, embolization procedure, and outcomes.
RESULTS:
Angiograms revealed extravasation (n = 10) or pseudoaneurysm (n = 4) in all patients. The causes of PPH were hysterotomy or hysterectomy related arterial injury (n = 11), cervical laceration (n = 2), and abnormal placentation (n = 1). UAE was performed with NBCA in all patients. Additional UAE with gelatin sponge particles was performed in two patients. Additional non-uterine artery embolization was performed in three patients. Coagulopathy was found in five (35.7%) patients. The technical and clinical success rates were 92.9% and 85.7%, respectively. One patient died from multi-organ failure eight days after UAE. One patient with abnormal placentation had pelvic organ ischemia due to multiple pelvic artery embolization.
CONCLUSION
UAE using NBCA is safe and effective for the patients with PPH showing extravasation or pseudoaneurysm.

Statins mediate vascular protection and reduce the prevalence of cardiovascular diseases. Recent work indicates that statins have anticonvulsive effects in the brain; however, little is known about the precise mechanism for its protective effect in kainic acid (KA)-induced seizures. Here, we investigated the protective effects of atorvastatin pretreatment on KA-induced neuroinflammation and hippocampal cell death. Mice were treated via intragastric administration of atorvastatin for 7 days, injected with KA, and then sacrificed after 24 h. We observed that atorvastatin pretreatment reduced KA-induced seizure activity, hippocampal cell death, and neuroinflammation. Atorvastatin pretreatment also inhibited KA-induced lipocalin-2 expression in the hippocampus and attenuated KA-induced hippocampal cyclooxygenase-2 expression and glial activation. Moreover, AKT phosphorylation in KA-treated hippocampus was inhibited by atorvastatin pretreatment. These findings suggest that atorvastatin pretreatment may protect hippocampal neurons during seizures by controlling lipocalin-2-associated neuroinflammation.
