Background/Aims: Effect of proton pump inhibitor (PPI) use on the risk of hipfracture is controversial. This study aimed to clarify the association between PPIuse and hip fracture risk using a large cohort. Methods: This study recruited participants from the nationwide cohort (n =1,025,340). After exclusion of participants who had hip fractures or were aged less than 40 years during the baseline period (2002 to 2004), 371,806 participants were followed to 2013. Participants prescribed PPIs for more than 90 days during baseline period were defined as users. Fracture cases were defined when participants were hospitalized with claims of a hip fracture. Results During 4,159,343 person-years of follow-up, fractures developed more oftenin PPI users than in nonusers (relative risk [RR], 1.787; 95% confidence interval [CI], 1.260 to 2.534; p = 0.002). The results persisted after adjusting for age, sex, andmany drugs relevant to osteoporosis or influential in bone health. Furthermore,fracture risk associated with PPI use increased with duration of use ( p trend < 0.001). The fully adjusted RRs of hip fracture development were 1.350 (95% CI, 1.203 to 1.515) for 1- to 90-day users, 1.487 (95% CI, 0.957 to 2.311) for 91- to 180-day users, and 1.771 (95% CI, 0.931 to 3.368) for > 180-day users. The positive association between PPI use and fracture was also confirmed in a subgroup with health screening data where further adjustment for body mass index, smoking status, alcohol consumption, and physical activity was available (adjusted RR, 2.025; 95% CI, 1.151 to 3.564, p = 0.014). Conclusions: PPI use is associated with hip fracture development.

CHARGE syndrome is a rare genetic disorder with CHD7 gene mutation. CHARGE is an acronym for coloboma (C), heart disease (H), atresia of choanae (A), retardation of growth (R), genitourinary malformation (G), and ear abnormalities (E). Patients with CHARGE syndrome need to undergo many surgeries due to their various congenital anomalies. Since airway abnormalities frequently accompany CHARGE syndrome, general anesthesia remains a challenge. Here we report a case of difficult intubation in a 35-month-old boy with CHARGE syndrome during general anesthesia and the experience of successful intubation using D-blade of C-MAC® video laryngoscope.

In this case report, we describe the use of ultrasound in the administration regional anesthesia for a super-super obese patient. A 23-year-old female patient (height 167.2 cm, weight 191.5 kg, body mass index 68.6 kg/m²) was admitted to the hospital for surgical repair of an anterior talofibular ligament rupture. We used ultrasound to help facilitate the administration of regional anesthesia. In the sagittal view of the lumbar spine, (with the patient in a sitting position) we were able to identify the border between the sacrum and the lumbar vertebral; in the transverse view, we were able to identify the transverse process, posterior dura, vertebral body, and the distance from the skin to the posterior dura. After skin marking, regional anesthesia was successfully performed. Based on this case study, we suggest that ultrasound can be very useful in regional anesthesia for severely obese patients.

A 72-year-old man underwent spinal anesthesia for artificial urinary sphincter placement for urinary incontinence. After the block level was confirmed below T6, 1 g of cefotetan, which had not shown any reaction on skin test, was administered as a prophylactic antibiotic. The patient began complaining of chest discomfort and dyspnea shortly after injection. ST elevation appeared on the electrocardiogram and the patient's pulse could not be palpated. Accordingly, cardiopulmonary resuscitation was performed for 5 minutes; the patient recovered spontaneous circulation. The patient was diagnosed as experienced coronary artery spasm by coronary angiography with spasm test. Because coronary artery spasm can also develop in patients with no history of coronary artery disease and under spinal anesthesia, careful observation, suspicion of coronary artery spasm and prompt response to hemodynamic and electrocardiogram changes are necessary.

Knotting of a pulmonary artery catheter (PAC) is a rare, but well-known complication of pulmonary artery (PA) catheterization. We report a case of a double-knotted PAC with a large loop in a patient with hepatocellular carcinoma (HCC) undergoing liver transplantation, which has been rarely reported in the literature. A PAC was advanced under pressure wave form guidance. PAC insertion was repeatedly attempted and the PAC was inserted 80 cm deep even though PAC should be normally inserted 45 to 55 cm deep. However, since no wave change was observed, we began deflating and pulling the balloon. At the 30-cm mark, the PAC could no longer be pulled. Fluoroscopy confirmed knotting of the PAC after surgery (The loop-formed PAC was shown in right internal jugular vein); thus, it was removed. For safe PA catheterization, deep insertion or repeated attempts should be avoided when the catheter cannot be easily inserted into the pulmonary artery. If possible, the insertion of PACs can be performed more safely by monitoring the movement of the catheter under fluoroscopy or transesophageal echocardiography.

Extreme thrombocytosis in patients with ankylosing spondylitis (AS) is rarely reported. Because the relationship between high disease activity and increased platelet counts is somewhat contradictory, severe thrombocytosis in AS patients can be secondary to infection, iron deficiency anemia, drug administration, and hematologic malignancies. Essential thrombocythemia (ET) is a rare acquired stem cell neoplasm characterized by overproduction of platelets by megakaryocytes in the bone marrow in the absence of other causes of thrombocytosis. There is no report in the literature regarding the association between AS and ET. We report on a case of a 34-year-old Korean man with active AS diagnosed as JAK2V617F mutation negative ET during adalimumab treatment.

PURPOSE: The mutation of the SLC26A4 gene is the second most common cause of congenital hearing loss after GJB2 mutations. It has been identified as a major cause of autosomal recessive nonsyndromic hearing loss associated with enlarged vestibular aqueduct and Pendred syndrome. Although most studies of SLC26A4 mutations have dealt with hearing-impaired patients, there are a few reports on the frequency of these mutations in the general population. The purpose of this study was to evaluate the prevalence of SLC26A4 mutations that cause inherited deafness in the general Korean population. MATERIALS AND METHODS: We obtained blood samples from 144 Korean individuals with normal hearing. The samples were subjected to polymerase chain reaction to amplify the entire coding region of the SLC26A4 gene, followed by direct DNA sequencing. RESULTS: Sequencing analysis of this gene identified 5 different variants (c.147C>G, c.225G>C, c.1723A>G, c.2168A>G, and c.2283A>G). The pathogenic mutation c.2168A>G (p.H723R) was identified in 1.39% (2/144) of the subjects with normal hearing. CONCLUSION: These data provide information about carrier frequency for SLC26A4 mutation-associated hearing loss and have important implications for genetic diagnostic testing for inherited deafness in the Korean population.

Arterial dissections usually arise from an intimal tear and can allow the development of an intramural hematoma. Dissection occurs frequently in the aorta or its branches and also occurs commonly in the internal carotid or vertebro-basilar arteries. The condition is rare in the intracranial cerebral arteries, especially above the supraclinoid segment of the internal carotid artery. The diagnosis of arterial dissection used to be made by conventional cerebral angiography. But recently, magnetic resonance imaging (MRI) is helpful to diagnose arterial dissection. We report two cases of middle cerebral arterial dissection using MRI.

Popliteal artery entrapment syndrome (PAES) occurs when an abnormal anatomic relationship between the popliteal artery and the surrounding musculotendinous structures causes repeated arterial compression with exercise. The most commonly reported causes of this syndrome have been anomalies of the medial head of the gastrocnemius muscle as it relates to the course of the popliteal artery. PAES can result in calf claudication, aneurysm formation, distal arterial emboli, or popliteal vessel thrombosis. This syndrome is a rare but potentially limb threatening anatomical anomaly occurring predominently in young adults. We experienced two cases who have suffered from a coldness and pain of lower leg. Angiogram and MRI were performed and we diagnosed as a popliteal artery entrapment syndrome. We report two cases of rare anomalous origin of the gastrocnemius muscle in intraoperative findings.

Traumatic dissection of the aorta is a fatal injury that requires rapid diagnosis and treatment. In assessing acute thoracic aortic injury, transesophageal echocardiography (TEE) has recently compared favorably with standard diagnostic modalities such as computed tomography, magnetic resonance imaging and aortography. These latter include time-consuming, contrast injection and the transportation of the patient to another area, requiring the interruption of resuscitative efforts. But, TEE includes less invasive nature, shorter procedure time, no contrast injection, portability at bedside, ability to be done concurrently other procedures such as resuscitation or hemodynamic monitoring and has high sensitivity and specificity for the evaluation of trauma patients with suspected injuries of the thoracic aorta. TEE may be suggested as primary diagnostic modality in suspected traumatic aortic injury in emergency department. We report two cases of traumatic aortic dissection diagnosed early by transesophageal echocardiography in the emergency department.
