In the following report, we describe the case of a rapidly skeletonized corpse discovered in late summer. On the first day of September, a 57-year-old man was found almost completely skeletonized on a hill behind his house. His body lay prone, accompanied by a brush cutter at the entrance to the graveyard where his friend's parents were buried. His cap, clothes, and rubber boots were all intact and undamaged. Upon autopsy, no definite abnormalities were identified except for an old linear fracture on the frontoparietal bone. According to his friends and neighbors, he had likely died 8 or 9 days prior to the discovery of his body.

Objective: To investigate the characteristics of the palmar cutaneous branch of the median nerve (PCBMN) in patient with carpal tunnel syndrome (CTS) using high-resolution ultrasound. Methods: Fourteen healthy volunteers (17 wrists) and 31 patients with CTS (41 wrists) were evaluated by high-resolution ultrasound. All patients were classified into three groups based on the electrophysiologic CTS impairment severity: mild, moderate, and severe. Using high-resolution ultrasound, the cross-sectional areas (CSAs) of the PCBMN were measured at the proximal wrist crease, bistyloid line, and distal wrist crease, and the largest CSA was defined as the maximal CSA. Results: The maximal CSA of the PCBMN of the control, mild, moderate, and severe CTS groups were 0.27±0.08, 0.30±0.07, 0.35±0.10, and 0.47±0.13 mm2, respectively. The maximal CSA of the PCBMN was significantly larger in the severe CTS group than in the other groups. Conclusion The PCBMN could be concomitantly affected in patients with severe CTS.

Tuberculosis (TB) is one of the most important occupational risks for healthcare workers (HCWs) in South Korea. Many policies regarding the control and prevention of TB in healthcare settings recommend that HCWs are tested for latent tuberculosis infection (LTBI) in addition to active TB. Moreover, the Korean Tuberculosis Prevention Act also recommends that HCWs receive regular testing for LTBI. However, there are no specific or detailed guidelines for dealing with LTBI in HCWs. Herein, we discuss the diagnosis and treatment of LTBI in HCWs and focus particularly on the baseline screening of hired HCWs, routine follow-up, and contact investigation.

A 39-year-old man, his 35-year-old wife, and their 13-year-old daughter were found dead in their home. The man and his daughter were found lying in her bedroom, with his head wrapped in a plastic bag connected to four helium gas cylinders by green polypropylene tubes. Fragments of the burnt ignition briquette were found in the bucket located at her feet. His wife was found in a decomposed state lying on her right side in her bedroom. Autopsy findings for the man were unremarkable except for cherry pink lividity; the blood carboxyhemoglobin concentration was 73%. Autopsy findings were unremarkable for the woman as well, except for a few petechial hemorrhages and conjunctival congestion. The daughter showed no definite abnormalities; however, her blood and lung contained helium gas. The deceased man's suicide note, evidence gathered at the scene, and postmortem examination revealed that this was a case of dyadic death.

OBJECTIVE: Low cholesterol is associated with depression among western countries. The objective of this study was to examine the relationship between cholesterol and depression in Korean population with low levels of serum cholesterol. METHODS: The data of about 740,000 individuals, aged 30-64 years at entry in the Korean Cancer Prevention Study, were used. Total cholesterol levels were measured in 1992. Depression was measured using the modified DSM-IV (Diagnostic Criteria of Major Depressive Episode in Diagnostic and Statistical Manual of Mental Disorders-IV) scale. Total cholesterol was classified into four groups (quartile). Odds Ratios of low level of cholesterol were evaluated using multi-variable logistic models. RESULTS: The prevalence of major depression was 7.7% in men and 10.4% in women. After adjustment for various confounding variables, an inverse association was detected between cholesterol levels and depression intensity among men and women. The odds ratio (95% confidence interval) of the lowest quartile of cholesterol was 1.16 (1.13-1.20) on major depression compared with the highest quartile of cholesterol in men. The corresponding odds ratio among women was 1.09 (1.04-1.15). The strongest association among 9 items of depression was found at "decreased appetite and lost weight" in both men (OR=1.68) and women (OR=1.43). CONCLUSION: Low cholesterol is associated with major depression in men and women. Further studies are necessary to evaluate the cross-validation, to explore the biological mechanism, and to identify the clinical implication.

Detailed information on additional drug resistance patterns of multidrug-resistant tuberculosis (MDR-TB) is essential to build an effective treatment regimen; however, such data are scarce in Korea. We retrospectively analyzed the results of phenotypic drug susceptibility testing (DST) of culture confirmed-TB patients from January 2010 to December 2014 in 7 university hospitals in Korea. MDR-TB was identified among 6.8% (n = 378) of 5,599 isolates. A total of 57.1% (n = 216) of the MDR-TB patients had never been treated for TB. Strains from MDR-TB patients showed additional resistance to pyrazinamide (PZA) (35.7%), any second-line injectable drug (19.3%), and any fluoroquinolone (26.2%). Extensively drug resistant TB comprised 12.4% (n = 47) of the MDR-TB patients. Of 378 MDR-TB patients, 50.3% (n = 190) were eligible for the shorter MDR-TB regimen, and 50.0% (n = 189) were fully susceptible to the 5 drugs comprising the standard conventional regimen (PZA, kanamycin, ofloxoacin, prothionamide, and cycloserine). In conclusion, the proportion of new patients and the levels of additional drug resistance were high in MDR-TB patients. Considering the high levels of drug resistance, the shorter MDR-TB treatment regimen may not be feasible; instead, an individually tailored regimen based on the results of molecular and phenotypic DST may be more appropriate in MDR-TB patients in Korea.

BACKGROUND: This study investigated the protective mechanism of Prostagladin E1 (PGE1) against intimal hyperplasia after vein interposition grafts in rabbits. It has been demonstrated that active oxygen species contribute to vascular smooth muscle cell growth via early cell cycle gene activation. We attempted to study whether PGE1 had an effect on the inhibition of the oxidative stress injury index (8-OHdG, MDA). METHODS: Forty-eight jugular vein grafts were inserted into the carotid arteries of male hyperlipidemic New Zealand white rabbits, which were divided into 2 groups (saline group and PGE1 group). Saline and Prostaglandin E1 (0.1 microgram/kg/min) were administered as a continuous infusion for 2 hours every day from just before graft interposition to harvest. The vein grafts were harvested at 6 hour, 1 day, 1 week, and 2 week after grafting and rapidly stored in liquid nitrogen ( 70oC). 8-OHdG was measured by using high performance liquid chromatography coupled with electrochemical detection (HPLC-EC), and malondialdehyde (MDA) was measured by using thiobarbituric acid (TBA) assay. PC 10 index and intimal thickness of the grafts were measured with a computer digitalized image analyzer. RESULTS: There was no difference in 8-OHdG levels between the saline and the PGE1 groups. PGE1 had more inhibitory effect on the MDA level as an oxidative stress injury index, but its action was restricted to 1 day. A morphometric analysis and an immunohistochemical study showed that the PGE1 group had more suppressive effects both in intimal thickeness and proliferating cell nuclear antigen (PCNA) expression than the saline group (p<0.05). CONCLUSION: These results suggest that PGE1 is effective in preventing intimal hyperplasia after vein interposition grafts in rabbits and may play a role in inhibiting oxidative stress injury.

Objective: To investigate the diagnostic accuracy of two physical examinations (straight leg raise [SLR] and Bragard test) and electromyography (EMG) in patients with lumbosacral monoradiculopathy in acute and chronic state on confirmation of different diagnostic criteria (MRI vs MRI and diagnostic selective nerve root block [DSNRB]). Method: We identified 297 participants retrospectively from the departmental database. MRI evidence of L5 or S1 nerve root compression and a positive result in diagnostic SNRB served as reference standards. They were divided into two groups by the symptom duration: lasting more than 12 weeks in the chronic group and less than 12 weeks in the acute group. The diagnostic value of clinical tests and EMG were compared. Results: The clinical tests (SLR and Bragard test) done in acute stage on detection by MRI and DSNRB had the highest sensitivity (68%) compared to the chronic stage (63%), but sensitivity was low (57%) on confirmation of MRI alone. However, there was no significant difference on sensitivity and specificity of EMG regardless of reference standards and symptom duration. Electromyography was a significant predictor of neuropathic abnormalities on both acute (OR, 6.3; 95% CI, 2.4 to 16.7; p＜0.01) and chronic (OR, 6.8; 95% CI, 2.9 to 16.3; p＜0.01). Conclusion In general, individual physical tests are easy to do and a combination of those tests could be a sensitive indicator of L5 or S1 radiculopathy.Furthermore, the use of provocation tests could provide useful information, especially in proceeding therapeutic selective nerve root block.
