Association between Female Urinary Incontinence and Geriatric Health Problems: Results from Korean Longitudinal Study of Ageing (2006) / 가정의학회지

BACKGROUND: Urinary incontinence (UI) is highly prevalent in the aging population. UI is one of the most common geriatric syndromes and affects overall health, quality of life, and economical burden in patients. The aims of this study were to investigate the characteristics of patients with UI and to assess its association with other geriatric health problems. METHODS: We used data from the Korean Longitudinal Study of Ageing obtained in 2006. Among the 10,254 individuals aged 45 years and older, we analyzed data from 2,418 women aged 65 years and older. Data were obtained using questionnaires for UI, comorbidities, and lifestyle factors. RESULTS: Among the 2,418 women aged 65 years and older, 506 (20.9%) had UI. Cerebrovascular disease (odds ratio [OR], 2.02; 95% confidence interval [CI], 1.26 to 3.23), arthritis (OR, 1.44; 95% CI, 1.18 to 1.77), and fear of falling (OR, 1.62; 95% CI, 1.18 to 2.22) were significantly associated with UI, while chronic lung disease, psychiatric disease, difficulty in daily living due to visual and hearing problems, and experiencing a fall in the last 2 years were not associated with UI. CONCLUSION: Cerebrovascular disease, arthritis, and especially fear of falls were significantly associated with UI in elderly Korean women.

Prevalence of Frailty and Aging-Related Health Conditions in Older Koreans in Rural Communities: a Cross-Sectional Analysis of the Aging Study of Pyeongchang Rural Area

Frailty has been previously studied in Western countries and the urban Korean population; however, the burden of frailty and geriatric conditions in the aging populations of rural Korean communities had not yet been determined. Thus, we established a population-based prospective study of adults aged > or = 65 years residing in rural communities of Korea between October 2014 and December 2014. All participants underwent comprehensive geriatric assessment that encompassed the assessment of cognitive and physical function, depression, nutrition, and body composition using bioimpedance analysis. We determined the prevalence of frailty based on the Cardiovascular Health Study (CHS) and Korean version of FRAIL (K-FRAIL) criteria, as well as geriatric conditions. We recruited 382 adults (98% of eligible adults; mean age: 74 years; 56% women). Generally, sociodemographic characteristics were similar to those of the general rural Korean population. Common geriatric conditions included instrumental activity of daily living disability (39%), malnutrition risk (38%), cognitive dysfunction (33%), multimorbidity (32%), and sarcopenia (28%), while dismobility (8%), incontinence (8%), and polypharmacy (3%) were less common conditions. While more individuals were classified as frail according to the K-FRAIL criteria (27%) than the CHS criteria (17%), the CHS criteria were more strongly associated with prevalent geriatric conditions. Older Koreans living in rural communities have a significant burden of frailty and geriatric conditions that increase the risk of functional decline, poor quality of life, and mortality. The current study provides a basis to guide public health professionals and policy-makers in prioritizing certain areas of care and designing effective public health interventions to promote healthy aging of this vulnerable population.

Clinical Implications for Graft Function of a New Equation Model for the Ratio of Living Donor Kidney Volume to Recipient Body Surface Area

PURPOSE: We propose an equation that predicts graft function after kidney transplantation by using donated kidney volume and recipient body surface area (BSA). MATERIALS AND METHODS: Included were 261 cases of living kidney transplantation between 2007 and 2009. Preoperative computed tomography scans were performed and the donated kidney volume was measured by use of a three-dimensional reconstruction program (Ripidia). The estimated glomerular filtration rate (eGFR) was calculated by using the modification of diet in renal disease formula. Donated kidney volume, preoperative renal function, and demographic factors of both donors and recipients were evaluated as predictors. RESULTS: The mean ages of the donors and recipients were 40.8 and 41.6 years, respectively. The mean donated kidney volume and donated kidney volume/recipient BSA ratio were 153.4 mL and 96.9 mL/m2, respectively. Mean preoperative and postoperative 12-month eGFR of recipients were 7.1 and 59.7 mL/min, respectively, and the mean preoperative eGFR of donors was 92.2 mL/min. Donated kidney volume/recipient BSA ratio, donor age, and recipient gender were the significant predictors of eGFR level (p<0.001) and eGFR<45 mL/min at postoperative 12 months (p=0.005, p<0.001, and p=0.006). From the multiple linear regression equation and predicted probability from logistic regression, we could calculate the equation for the ratio of living donor kidney volume to recipient BSA on graft function. CONCLUSIONS: Graft kidney volume/recipient BSA ratio, donor age, and recipient gender were predictors of graft function 12 months after kidney transplantation. Although we are concerned only with the preoperative, this equation model could help physicians to counsel patients concerning their postoperative prognosis and to avoid insufficient volume donations.

Clinical Outcomes of Bosniak Category IIF Complex Renal Cysts in Korean Patients

PURPOSE: To assess the clinical reliability of the Bosniak IIF category and to determine the proper radiologic follow-up duration and intervals for category IIF complex renal cysts. MATERIALS AND METHODS: We studied 201 patients with category IIF renal cysts from January 1996 to January 2011. Renal cyst progression to category III was defined as an increase in complexity of the cyst in follow-up radiologic studies. We monitored radiologic changes and progression of renal cysts during the follow-up period and analyzed the pathologic results of those patients who were treated surgically. RESULTS: At a mean follow-up of 20 months, only 14 cases (7%) showed evidence of progression to stage III, with a mean time to progression of 11 months (range, 3 to 65 months). There were no significant differences in age, gender, cyst size, or change in cyst size between the progressive and non-progressive groups. Of 12 cases treated surgically, 10 cases (83.3%) showed renal cell carcinoma with pT1 stage, and there was no recurrence during postoperative follow-up of 23 months. Of the 187 patients without radiologic progression, 23 cases were treated surgically, and all of them showed benign cysts. CONCLUSIONS: The IIF category showed significant clinical reliability by a low rate of radiologic progression and a high rate of malignancy in the radiologic progressive group but a low rate of malignancy in the non-progressive group. Although it is hard to decide on a proper follow-up duration because of the variable time to progression, too frequent follow-up study seems to be unnecessary considering that most malignant cases were of a low stage.

Large Oncocytic Adrenocortical Tumor with Uncertain Malignant Potential

Oncocytoma is a neoplasm consisting of oncocytes that is found in the salivary gland, kidney, and thyroid. Adrenocortical oncocytoma is particularly uncommon, and most cases reported are benign and nonfunctioning. Here, we report a 20 cm adrenal mass associated with necrosis that was identified as an oncocytic adrenocortical tumor with uncertain malignant potential through histopathological evaluation after its resection.

Tetraarsenic Oxide-mediated Apoptosis in a Cervical Cancer Cell Line, SiHa / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: Diarsenic oxide, As2O3, has been reported to be effective in treating acute leukemia, and induce apoptosis in many tumor cells. In this study, the ability of a novel arsenical compound, As4O6 (tetraarsenic oxide), along with As2O3, for its ability to induce cell growth inhibition, as well as apoptosis, in human cervical cancer cells, SiHa cells, were evaluated in vitro. MATERIALS AND METHODS: To examine the levels of apoptosis, SiHa cells were given two sensitive doses, 0.5 and 1micrometer, of arsenical compounds, and a DNA fragmentation assay and FACS analysis were then conducted. In addition, a Western blotting assay was performed to identify target molecules for apoptosis. RESULTS: Both As2O3 and As4O6 induced dose-dependent inhibition of SiHa cell proliferation. In particular, As4O6 was more effective at suppressing SiHa cell growth than As2O3. In parallel with the inhibition of cell proliferation, As4O6 caused a significantly greater increase in the sub-G1 cell population than As2O3, as determined by propidium iodide DNA staining. This was confirmed by a DNA fragmentation assay and annexin V staining. The Western blotting analysis also showed that the expression of proliferating cell nuclear antigen (PCNA) was suppressed to a significantly greater extent by As4O6 than As2O3 at a dose of 0.5micrometer. However, the apoptosis-related protein, Bax, was expressed to a significantly greater extent due to As4O6 than As2O3. CONCLUSIONS: Taken together, these findings suggest that a novel arsenic compound, As4O6, possesses more potent anti-proliferative effects on human cervical cancer cells, with the induction of apoptosis also, at least via the activation of Bax protein in vitro.

Clinical Values of Fine Needle Aspiration Biopsy in Salivary Gland Diseases / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Diversity of opinion regarding the impact of fine needle aspiration biopsy (FNAB) on clinical decision-making has persisted, mostly because of its high false-negative rate and lower sensitivity in salivary gland diseases when compared to other head and neck tumors. The objectives of this study are to evaluate the utility of FNAB in the diagnosis of salivary gland pathologies and to assess its capacity to provide an accurate medical and surgical treatment. MATERIALS AND METHODS: From June 1989 through January 2000, FNABs were carried out on 50 patients with salivary gland diseases. Among them, 34 patients were confirmed histologically after surgery and others clinically. RESULTS: Regarding the capacity of FNAB to discriminate between neoplastic (malignant and benign) and non-neoplastic lesions, FNAB correctly diagnosed 87% (41/47) of lesions. The values for sensitivity, specificity and accuracy of differentiation for neoplastic lesions were 17%, 95% and 87%, respectively. FNAB's diagnostic accuracy, sensitivity and specificity to Warthin's tumor was higher than to those of pleomorphic adenoma. CONCLUSION: Fine needle aspiration biopsy of salivary gland diseases is a helpful adjunctive test for diagnosis and treatment planning.

A Case of Benign Fibrous Histiocytoma of Frontoethmoid Sinus / 대한이비인후과학회지

Fibrous histiocytoma or other tumors of this group, benign or malignant, usually develop indiscriminately in any skin and soft tissues of the body. Up to the present, tumors occurring in the nasal cavity, paranasal sinuses or nasopharynx have been rarely reported. Most benign fibrous histiocytoma often develop as a painless mass lesion and mostly occur in the-sun-exposed skin and orbital tissue. However, it has also been found in the aerodigestive tract, salivary gland, and deep layers of the scalp and face. The age ranges from 1 to 70 with a male to female ratio of 2.5:1. Recently, we experienced a case of benign fibrous histiocytoma in the frontoethmoid sinus in a 63-year-old woman, whose case was initially considered as a mucocele. The authors believe this is the first reported case of benign fibrous histiocytoma originating in the frontoethmoid sinus.

A Case of Embryonal Rhabdomyosarcoma of Nasal Cavity in Adult / 대한이비인후과학회지

A rare case of the nasal cavity and paranasal sinus is encountered and we report the case with the literature review of embryonal rhabdomyosarcoma. The occurrence of embryonal rhabdomyosarcoma in nasal cavity and paranasal sinus is rather uncommon. Most embryonal rhabdomyosarcoma occurs in children younger than 12 years of age, and in adult, the incidence is only 10%, Recently, we experienced a case of adult embryonal rhabdomyosarcoma originating in the nasal cavity. The clinical course and the possible management of this unusual neoplasm are discussed.

A Case of Relapsing Polychondritis / 대한류마티스학회지

Relapsing polychondritis is an uncommon disease manifested by episodes of progressive inflammation and destruction of cartilage. While the cause remains unknown, an autoimmune pathogenesis appears likely. Characteristic features include auricular chondritis, arthritis, nasal chondritis, ocular inflammation, respiratory tract involvement and audiovestibular damage. The clinical course of patients may vary from a relatively benign illness free of clinically evident visceral involvement, to one of episodic or smoldering activity with variable intensity, to a f ulminant illness and death within months of diagnosis. Dapsone, corticosteroid and immunosuppressive agent remain the effective therapies. We have experienced a case of relapsing polychondritis and active pulmonary tuberculosis in a 69-year-old man. He suffered from arthralgia and swelling of joints for several months on the first admission and initially was diagnosed as pseudogout based on polyarthritis and chondrocalcinosis of right knee joint. During follow-up, chondritis of both auricles and nose, which was proved by the biosy of right auricle, and relapse of polyarthritis were developed. His spu tum smear for acid-fast bacillus was postive on the second admission. Then he was diagnosed as relapsing polychondritis and active pulmonary tuberculosis and has achieved improvement with medication of dapsone and antituberculosis drugs according to susceptability test during followed-up. Thus we report this case with literature review.
