The etiologies of sudden sensorineural hearing loss (SSNHL) include idiopathic, viral infections, vascular occlusion, abnormal cellular stress responses within the cochlea, and a variety of immune-mediated mechanisms. Although idiopathic cause is most common, many studies have proposed a possible association between SSNHL and viral infections, including herpes simplex virus, human immunodeficiency virus (HIV), rubella, mumps, and so on. Particularly, various mechanisms underlying auditory dysfunction in the HIV/acquired immune deficiency syndrome have been proposed. Herein, we present the case of a 35-year-old male diagnosed with sudden hearing loss on both sides and left acute otitis media, presenting first in the left ear, in which subsequent serological examination revealed HIV infection. It is a case of HIV infection diagnosed after identifying the involvement of the 8th cranial nerve as the first symptom in the absence of any other HIV infection-associated symptoms.

The authors evaluated the incidence of hip fracture and subsequent mortality in Korea using nationwide data obtained from the Health Insurance Review and Assessment Service. This study was performed on patient population, aged 50-yr or older who underwent surgical procedures because of hip fracture (ICD10; S720, S721). All patients were followed using patient identification code to identify deaths. Crude hip fracture rates increased from 191.9/100,000 in 2005 to 207.0/100,000 in 2008 in women and from 94.8/100,000 in 2005 to 97.8/100,000 in 2008, in men respectively. Crude mortality within 12 months after hip fracture showed a similar trend (18.8% in 2005 and 17.8% in 2007). The mean of standardized mortality ratio of hip fracture was 6.1 at 3 months, 3.5 at 1 yr, and 2.3 at 2 yr post-fracture. The increasing incidence and the high mortality after hip fracture are likely to become serious public health problems and a public health program should begin to prevent hip fractures in Korea.

BACKGROUND: Although osteoporosis is increasing in the elderly population, attempts to analyze the patterns of medical service utilization for osteoporosis are currently not sufficient. The medical services and treatment patterns were investigated using Korea's National Health Insurance claims data, which includes all of the Korean population. METHODS: Through the patient identification algorithm developed by using the administrative claims data in 2007, the adult patients (between 50-100 years) with osteoporosis were identified. The age and gender of the patients who used medical service for osteoporosis were described, in relation with six dichotomous variables. The medical service use patterns such as the type of medical institution and conducting bone mineral density measurement were investigated. RESULTS: The number of patients who used medical service were 1,230,580 (females 89.9%). Sixty one point six percent of the patients were prescribed osteoporosis medicine (indicated for osteoporosis only), and 12.9% of the patients had experienced osteoporotic fracture. The primary medical institutions for treatment were clinics (54.3%), while hospitals were mainly used among the patients with a history of fracture and disease or drug use that may induce secondary osteoporosis. The number of visited medical institutions was 6.4 (as an outpatient) and 0.2 (as admissions) during 6 months. The proportion of patients who conducted bone mineral density measurements within one year before and after the diagnosis of osteoporosis was 66.7% and DXA was the most frequently used densitometry (46.3%). The average number of days for the prescriptions for osteoporosis medicine was 70 days. CONCLUSION: In order to prevent further osteoporotic fractures, appropriate management and treatment should be implemented for osteoporosis patients. To do this, we need to understand the current state of medical service utilization and the treatment of osteoporosis using the National Health Insurance claims data.

BACKGROUND: There has been lack of epidemiology of proximal humerus fracture using nationwide database in Asia. The purpose of this study was to investigate the incidence of proximal humerus fracture and its mortality following proximal humerus fracture in Korean over 50 years of age. METHODS: The Korean National Health Insurance data were evaluated to determine the incidence and mortality of proximal humerus fracture aged 50 years or older from 2008 through 2012. RESULTS: Proximal humerus fracture increased by 40.5% over 5 year of study. The incidence of fracture increased from 104.7/100,000 in 2008 to 124.7/100,000 in 2012 in women and from 45.3/100,000 in 2008 to 52.0/100,000 in 2012 in men, respectively. One year mortality rate after proximal humerus fracture was 8.0% in 2008 and 7.0% in 2012. One year mortality rate were 10.8% for men and 7.0% for women in 2008 and 8.5% for men and 6.4% for women in 2012. CONCLUSIONS: Our study showed that the proximal humerus fracture in elderly was recently increasing and associated with high mortality in Korea. Considering proximal humerus fracture was associated with an increased risk of associated fractures and an increased mortality risk, public health strategy to prevent the proximal humerus fracture in elderly will be mandatory.

BACKGROUND AND OBJECTIVES: The renin-angiotensin system (RAS) genes have been studied extensively as etiologic essential hypertension (EH) candidate genes in human populations worldwide. The angiotensin I-converting enzyme (ACE) plays an important role in the RAS for the regulation of blood pressure. Recent reports on the association of ACE gene polymorphisms with EH and the related cardiovascular diseases have been controversial. Therefore, this study investigated the association of three polymorphisms (I/D, G14480C and A22982G) in the ACE gene with EH in Koreans. SUBJECTS AND METHODS: This study recruited a sample population of 887 Koreans (comprising of 461 controls and 426 EH cases) from Cardiovascular Genome Center in Korea. The ACE gene polymorphisms were determined by a polymerase chain reaction and a SNP-IT assay. RESULTS: The genotype and the allele frequencies of all three polymorphisms in the hypertensives and the normotensives not significantly different (p>0.05). In the female control group, there was a significant difference in SBP among the genotype with the I/D polymorphism (p<0.05). There was also an association between the ACE polymorphisms and the hypertensive male group with the total cholesterol level. Haplotype analysis showed that none of the haplotypes were significantly associated with hypertension. CONCLUSION: ACE polymorphisms do not appear to have any apparent association with essential hypertension in Koreans, who have a more homogeneous genetic structure than other ethnic groups.

Platelet membrane receptor glycoproteins (GP) are essential for the platelet activation process, and the genetic polymorphisms in the genes that encode platelet glycoproteins have been proposed to influence the risk of acute coronary syndrome and atherosclerosis. In this study, we investigated the role of GPIa, HPA-1 and HPA-3 polymorphisms as putative risk factors for myocardial infarction (MI) and the extent of coronary artery disease. We selected 1, 073 subjects who underwent coronary angiography; 242 had normal or minimal coronary atherosclerosis, and 831 patients had significant coronary artery disease (CAD). The genotype was determined by the methods of single base extension for C807T/G873A polymorphisms of GPIa, and restriction fragment length polymorphism for HPA-1 and HPA-3. The C807T and G873A polymorphisms of GPIa showed complete linkage in the Korean population. For HPA-1 gene polymorphism, only the HPA-1a/a (PlA1/A1) genotype was observed in 192 selected subjects from our study population. The distribution of GPIa (C807T/G873A) and HPA-3 genotypes did not differ significantly between normal subjects and CAD subjects. No significant association between MI and both gene polymorphisms was present. However, for the subgroup analysis of young male patients whose age was less than 56 years, the genotype frequency of HPA-3b/b was significantly lower in patients with MI compared to patients without a history of MI (7.5% vs. 20.0%, p=0.04). The odds ratio for HPA-3 b homozygosity versus the HPA-3a carrier was 0.32 (95% CI, 0.10- 0.99, p=0.04). Conclusively, HPA-3 polymorphism was associated with MI in Korean individuals younger than 56 years of age, but other polymorphisms of GP, which we studied, were not associated with both the extent of coronary atherosclerosis or MI.

Objective:
To evaluate and assesse useful factors in predicting early preterm birth (PTB) and de termined the increased risks of early PTB for the combinations of these factors compared to late PTB.
Methods:
The 77 singleton pregnancies with PTL were enrolled. They had undergone examinations including cervical length (CL) and fetal fibronectin (fFN), polymerase chain reaction for sexually transmitted disease, and cervical culture. We first evaluated the statistical significance of the primary predictors (known risk factors before pregnancy) and secondary predictors (fFN, CL, high-sensitivity C-reactive protein [hsCRP] and cervical bacterial analysis). Next, we analyzed the various combinations of meaningful factors.
Results:
CL <2.5 cm (P=0.007; odds ratio [OR], 3.598), hsCRP ≥0.9 mg/dL (P=0.011; OR, 3.79), and fFN ≥50 ng/mL (P=0.035; OR, 2.75) were more predictive of early PTB than late PTB. The highest OR was observed for the combination of all 3 factors (P=0.039; OR, 7.75). The fFN positivity and hsCRP ≥0.9 mg/dL was in OR 6.094 (P=0.013). The CL<2.5 cm and hsCRP ≥0.9 mg/dL was in OR 5.333 (P=0.009). Finally, the CL <2.5 cm and fFN positivity was in OR 3.946 (P=0.013). The interval between diagnosis and delivery in women with all 3 factors was 8 days shorter than that for women without these factors (P=0.04).
Conclusion
Our study is the first to demonstrate the potential risks of PTB using the combination of commonly used in clinical factors, and revealed quantification by the ORs. We will be useful reference value for patients counselling for prediction of early PTB.
