Granulosa cell tumor of the testis is extremly rare in adult males and granulosa cell tumor occurring in the paratesticular area has not been reported. We report a paratesticular granulosa cell tumor in a 34-year-old man who presented with a 5.5 cm sized scrotal mass. The tumor was present in the paratesticular area near the head of epididymis. It was located in the tunica and completely separated from the testis by thick fibrous tissue. Microscopically, the tumor exhibited solid, microfollicular, and trabecular patterns. The tumor cells had ovoid to elongated nuclei with longitudinal intranuclear grooves and one or two nucleoli and scanty cytoplasm. Mitoses were relatively frequent with an average number of 9/10 HPFs. The tumor extended into the visceral tunica vaginalis and showed multiple lymphatic tumor emboli. Immunohisto chemical stains revealed diffuse strong positivity for inhibin, vimentin, and keratin and diffuse weak positivity for estrogen and progesteron receptor. Placental alkaline phosphatase (PLAP) and epithelial membrane antigen (EMA) were negative. On electron microscopic examination, tumor cells were polygonal and had large indented nuclei. The cytoplasm contained a moderate number of small round mitochondria, abundant rough and smooth endoplasmic reticula, and a few lipid droplets. Small aggregates of intermediate filaments and intercellular junctions were observed. The patient was alive and well 5 months after orchiectomy. This is the first case of adult granulosa cell tumor arising in the paratesticular area.

OBJECTIVE: The aim of the study was to identify factors influencing the willingness of healthcare consumers to use personal health records (PHR) and to investigate the requirements for PHR services. METHODS: A face-to-face interview was conducted with 400 healthcare consumers from the 3rd-18th of July 2008 using a structured questionnaire. To identity factors affecting the willingness to use PHR and to pay for PHR services, logistic regression analysis was performed. To investigate the requirements for PHR services according to the willingness of the consumers to use PHR and to pay for PHR services, t-test analysis was conducted. RESULTS: Of the 400 healthcare consumers, 239 (59.8%) were willing to use PHR and 111 (27.8%) were willing to pay for PHR services. The willingness to use PHR was higher in the elderly, those with a disease, and those with experience to use health information on the Internet, and the willingness to pay for PHR services was higher in those with a relatively high income (p<0.05). The willingness to use PHR was approximately 13.5 (95% CI=1.43-126.55) and 3 times (95% CI=1.18-8.74) higher in those with average monthly household incomes >6,000,000 won and 4,500,000-6,000,000 won, respectively, than in those earning <1,500,000 won, and approximately 1.96 times (95% CI=1.18-3.27) higher in those with experience using health information on the Internet than in those without experience. The willingness to pay for PHR services was approximately 5.9 times (95% CI=1.84-19.06) higher in those with an income of 4,500,000-6,000,000 won than in those with an income <1,500,000 won (p<0.05). Demands for test results, medication history, family history, problem list, genetic information, clinical trial information, and social history were significantly higher in those with a willingness to use PHR and those with a willingness to pay for PHR services than in those without willingness to use PHR and those without a willingness to pay for PHR services (p<0.05). Compared to those without a willingness to pay for PHR services, those with a willingness to pay for PHR services showed a significantly higher demand for all the functions (p<0.01). CONCLUSION: The results of this study suggest that healthcare consumers potentially have a considerable demand for PHR services, and although it is not recognized and used widely yet, PHR is an essential service. In order to enhance people's awareness of PHR and to promote people to use PHR services, we need efforts and initiatives to execute campaigns and education for people to ease access to the service, and to reduce the gap in service utilization skills.

Morphological development of the ciliary body was studied by electron microscope in human fetuses from 50 to 260 mm crown-rump length(11-30 weeks of gestational age). At a 50 mm(11 weeks) fetus, the anlage of ciliary body was not appeared. At a 70 mm(13 weeks) fetus, the anlage of ciliary epithelium was appeared as the folds were formed by invaginating vessels in the basal surface of pigmented epithelium at the rim of optic cup. At the time, the anlage of ciliary muscle was formed as the mesenchymal cells, which located between the rim of optic cup and the scleral condensation, different-iate into the myoblasts, and the unmyelinated nerve fibers and the axon terminals were found in the interstitial tissue of mesenchyme. At 100-260 mm(15-30 weeks) fetuses, the myoblasts of ciliary body continued to develop into typical smooth muscle cells. At 200-260 mm(20-30 weeks) fetuses, the well-developed infoldings in the basal lamina and the well-developed interdigitations in the lateral sur-face were observed at both pigmented and nonpigmented epithelia. At the time, ganglion cells, Schwan cells and axon terminals were observed in the interstitial tissue of ciliary muscle.

Klebsiella pneumoniae has been reported to be the most common pathogen causing pyogenic liver abscess. K. pneumoniae liver abscess occurs fairly often in patients with diabetes mellitus, and is commonly associated with metastatic infections such as brain abscess, endophthalmitis, lung abscess, osteomyelitis, prostatitis, necrotizing fasciitis and infection in other sites. Although septic pulmonary embolism (SPE) is uncommon, it is a serious metastatic complication of K. pneumoniae liver abscess. Chest computed tomography (CT) scans are crucial in making the early diagnosis of SPE; however, it does not provide the basis for a definitive diagnosis. A 70-year-old man was referred to the Department of Pulmonology due to cough and an abnormal chest radiography. The chest CT scans revealed relatively well-demarcated, round multiple nodules with peripheral preponderance, cavitary mass in the right upper lobe of the lung and low-density hepatic cystic masses. Bronchoscopic examination and percutaneous needle aspiration of the lung were performed, but there was no evidence of malignancy. Finally, K. pneumoniae was grown from a bronchial washing specimen and blood culture. Intravenous carbapenem was administered over a 3-week period and follow-up CT scans showed improvement in both the lung and the liver. We report a case of K. pneumoniae liver abscess complicated with SPE requiring differential diagnosis of hematogenous metastatic malignancy on CT scans in an elderly patient.

BACKGROUND: Static parameters such as central venous pressure and pulmonary artery occlusion pressure, have limitation in evaluation of patients' volume status. Dynamic parameters such as stroke volume variation (SVV), have been used to evaluate intraoperative hemodynamic volume status, in various operations. We examined if SVV is also effective for patients undergoing operation with prone position for fluid management. METHODS: Eighteen patients that received spinal surgery under prone position November 2015 to May 2016, were enrolled. Patients were kept at an SVV value less than 14% during surgery. Changes of pre-, post-operative volume status were evaluated, using transthoracic echocardiography. RESULTS: Mean fluid administered was 1,731.97 ± 792.38 ml. Left ventricular end-diastolic volume was 72.85 ± 13.50 ml before surgery, and 70.84 ± 15.00 ml after surgery (P value = 0.594). Right ventricular end-diastolic area was 15.56 ± 1.71 cm² before surgery, and 13.52 ± 2.65 cm² after surgery (P value = 0.110). Inferior vena cava diameter was 14.99 ± 1.74 mm before surgery, and 13.57 ± 2.83 mm after surgery (P value = 0.080). CONCLUSIONS: We can confirm that fluid management based on SVV is effective, even in prone position surgery. So, SVV, that can be measured by continuous arterial pressure, can be considered a guideline for effective fluid management in spinal surgery.

BACKGROUND: Maintenance of tracheal intubation is associated with use of sedatives, stress due to mechanical ventilation, or respiratory complications. The aim of this study is to compare the incidence of delirium between early and late extubation groups after liver transplantation (LT). METHODS: Medical records from 247 patients who received LT from January 2010 to July 2017 in a single university hospital were retrospectively reviewed. Patients were divided with 2 groups: Those who underwent early extubation after LT (E group, n = 52) and those who underwent extubation within few hours of intensive care unit (ICU) admission after surgery (C group, n = 195). The patients’ demographic data, perioperative managements and postoperative complications were collected. Early extubation was defined as performing extubation in the operating room after LT. A propensity score matching analysis was performed to reduce the effects of selection bias. RESULTS: Among them, 4/52 (7.69%) in E group and 30/195 (15.38%) in C group occurred postoperative delirium after LT, respectively (P = 0.180). After propensity score matching, there was no difference of the period of hospitalization in ICU (P = 0.961), time to discharge after surgery (P = 0.117) and incidence of delirium between groups (P = 1.000). CONCLUSIONS: Although this study is a retrospective study and limited by the small number of subjects, early extubation does not affect the incidence of delirium after LT. Therefore, further prospective studies on this were needed.

Actinomycosis is an indolent infectious disease characterized by pyogenic response and necrosis, followed by intense fibrosis. The main forms of human actinomycosis are cervicofacial, pulmonary, and abdominopelvic type. Pulmonary actinomycosis accounts for 15% to 20% of total cases and unfortunately, clinical manifestations and radiologic findings are nonspecific. Small pleural effusion or empyema may develop in advanced disease but massive empyema is infrequent and rarely reported. We report a case of huge empyema caused by pulmonary actinomycosis in a 55 year-old man, presented with one-month history of productive cough and fever. The CT scan revealed a huge cavity with air-fluid level occupying the left hemithorax. Empyema caused by actinomycosis was confirmed microscopically by demonstration of sulfur granules in empyema sac through thracotomy. Decortication and surgical resection of empyema sac and destructed lung was accomplished and followed by intravenous infusion of penicillin G.

OBJECTIVE: The purpose of the present study was to investigate cardiovascular autonomic dysfunction in patients with Parkinson's disease (PD) with mild to severe stages of motor symptoms and to compare cardiovascular autonomic dysfunction between drug-naïve and dopaminergic drug-treated groups. METHODS: This study included 188 PD patients and 25 age-matched healthy controls who underwent head-up tilt-testing, 24-h ambulatory blood pressure (BP) monitoring and 24-h Holter monitoring. Autonomic function test results were evaluated among groups categorized by motor symptom severities (mild vs. moderate vs. severe) and treatment (drug-naïve or dopaminergic drug treatment). RESULTS: Orthostatic hypotension and supine hypertension were more frequent in patients with PD than in healthy controls. The frequencies of orthostatic hypotension, supine hypertension, nocturnal hypertension and non-dipping were not different among groups. Additionally, no significant differences were detected in supine BP, orthostatic BP change, nighttime BP, nocturnal BP dipping, or heart rate variabilities among groups. CONCLUSIONS: Cardiovascular autonomic dysfunction is not confined to moderate to severe PD patients, and starts early in the course of the disease in a high proportion of PD patients. In addition, dopaminergic drug treatments do not affect cardiovascular autonomic function.

BACKGROUND AND PURPOSE: Altered blood pressure (BP) and heart rate variations (HRVs) have been reported in Alzheimer's disease (AD). However, it is unclear how these two manifestations are associated with AD. Therefore, the objective of this study was to investigate BP and heart rate variability in AD compared to that in normal controls, patients with subjective memory impairment (SMI), and patients with mild cognitive impairment (MCI). METHODS: Case-control comparisons were made among AD (n=37), MCI (n=24), SMI (n=17), and controls (n=25). All patients underwent clinical and neuropsychological assessments with 24-h ambulatory BP and Holter monitoring. RESULTS: Patients with AD had higher pulse pressures than those in other groups. In addition, AD patients experienced blunted nocturnal BP dipping associated with declining cognitive status. AD patients also had larger ranges of HRV in parasympathetic domains compared to other groups, especially at night. CONCLUSIONS: Our results suggest that diurnal sympathetic and parasympathetic cardiac variability were significantly disturbed in mild cholinesterase-naive AD patients. This may be an indirect sign of disturbed integrity to the sleep-wake cycle in mild AD.

The prevalence of group B streptococcus (GBS) among pregnant women and disease burdens in neonates and adults are increasing in Korea. Colonizing isolates, collected by screening pregnant women (n=196), and clinical isolates collected from clinical patients throughout Korea (n=234), were serotyped and screened for antibiotic resistance. Serotype III (29.8%) and V (27.7%) predominated, followed by Ia (17.0%). Antibiotic resistance was higher among clinical than colonizing isolates for erythromycin (35.1% and 26.9%; P=0.10) and for clindamycin (49.4% and 42.1%; P=0.17). erm(B) occurred in 91.9% of erythromycin resistant isolates, and 84.0% of isolates resistant to clindamycin. Only five isolates (4.2%) resistant to erythromycin were susceptible to clindamycin; by contrast, and unique to Korea, 34% of isolates resistant to clindamycin were erythromycin susceptible. Among these 60 erythromycin-susceptible & clindamycin-resistant isolates, 88% was serotype III, and lnu(B) was found in 89% of strains. Four fifths of the serotype V isolates were resistant to both erythromycin and clindamycin. Further characterization of the genetic assembly of these resistance conferring genes, erm(B) and lnu(B), will be useful to establish the clonal lineages of multiple resistance genes carrying strains.
