PURPOSE: This study examined degrees of irrational parenthood cognition, post traumatic stress disorder (PTSD), spousal support, and quality of life and investigated factors that influence the quality of life of infertile women. METHODS: Research design was a cross sectional correlational survey with a total of 113 female patients receiving treatment for infertility. Data were collected from August 1 to November 30, 2015. The collected data were analyzed using t-test, ANOVA, Pearson's correlation, and multiple regression analysis. RESULTS: The mean score of the quality of life was 59.0±14.8. The quality of life was significantly associated with irrational parenthood cognition (r=-.70), post traumatic stress disorder (r=-.65), and spousal support (r=.56). The factors significantly affecting the quality of life in infertile women were irrational parenthood cognition (β=-.45), post traumatic stress disorder (β=-.34), and spousal support (β=.32). The explained variance by these factors was 70.4%, and the regression model was valid (F=89.81, p<.001). CONCLUSION: This study may contribute to the development of nursing intervention program to improve the quality of life of infertile women.

OBJECTIVES: Baso-apical gradients exist in various cochlear structures including medial olivocochlear (MOC) efferent system. This study investigated the cochlear regional differentials in the function and morphology of the MOC system, and addressed the functional implications of regional MOC efferent terminals (ETs) in the mouse cochlea. METHODS: In CBA/J mice, MOC reflex (MOCR) was assessed based on the distortion product otoacoustic emission in the absence and presence of contralateral acoustic stimulation. High, middle, and low frequencies were grouped according to a mouse place-frequency map. Cochlear whole mounts were immunostained for ETs with anti-α-synuclein and examined using confocal laser scanning microscopy. The diameters of ETs and the number of ETs per outer hair cell were measured from the z-stack images of the basal, middle and apical regions, respectively. RESULTS: The middle cochlear region expressed large, clustered MOC ETs with strong MOCR, the base expressed small, less clustered ETs with strong MOCR, and the apex expressed large, but less clustered ETs with weak MOCR. CONCLUSION: The mouse cochlea demonstrated regional differentials in the function and morphology of the MOC system. Strong MOCR along with superior MOC morphology in the middle region may contribute to ‘signal detection in noise,’ the primary efferent function, in the best hearing frequencies. Strong MOCR in spite of inferior MOC morphology in the base may reflect the importance of ‘protection from noise trauma’ in the high frequencies.

Children with abnormal sex development may present with ambiguous genitalia in the newborn period or lacking of secondary sexual characteristics in puberty. Clinicians should make a prompt and accurate diagnosis and counsel parents on therapeutic options to minimize or avoid medical and psychological complications. 5alpha-reductase deficiency is a rare autosomal recessive disorder of sex development caused by a mutation of the 5alpha-reductase type 2 gene. As a result, there is an abnormality in conversion of testosterone (T) to dihydrotestosterone (DHT) and children with 5alpha-reductase deficiency are born with ambiguous genitalia. Here, we report identical twins who presented with ambiguous genitalia with a 46,XY karyotype and were diagnosed as 5alpha-reductase deficiency.

A 23 months-old girl visited the hospital because of fever and left neck mass. She was diagnosed as acute suppurative thyroiditis with piriform sinus fistula. Thyroid sonography showed perithyroidal abscess formation and thyroid scan showed decreased uptake of Tc-99m pertechnate of both thyroid glands. Magnetic resonance imaging of neck showed abscess cavity extending to the swollen left thyroid gland. And there was tiny fistula between thyroid and piriform sinus in the barium esophagogram. Streptococcus gordonii was isolated on needle aspiration culture. We report a case of piriform sinus fistula of the neck complicated with suppurative thyroiditis. The fistula was treated with chemocauterization using trichloroacetic acid.

Heterotopic pancreas can be defined as the occurrence of pancreatic tissue at aberrant anatomic sites that lack vascular, neural and anatomic community with the pancreas. A minority of heterotopic pancreas elicit clinical signs or symptoms that can vary according to its location and size, and the involvement of the overlying mucosa. We report here on a case of heterotopic pancreas that was removed by pancreatoduodenectomy under the erroneous diagnosis of distal common bile duct cancer.

PURPOSE: The purpose of this study is to exam the effects of a short-term pulmonary program on lung function, exercise tolerance, and quality of life in chronic lung patients. METHOD: Randomized controlled pre-post test design was used. The outcome measures were forced expiratory volume in one second (FEV1, % predicted), 6 min walking distance (6MWD), Borg score after 6MWD, and Chronic Respiratory Disease Questionnaire (CRDQ). Experimental group performed the 4-week home-based pulmonary rehabilitation program composed of inspiratory muscle training, upper and lower extremity exercise, relaxation, and telephone visit. Patients in control group were only given education about self-management strategies. Thirty four patients with moderate-to-severe respiratory impairment were recruited, and 28 patients (19 in experiments, 15 in control) completed the study. RESULT: Significant improvements in lung function, exercise tolerance, and health related quality of life were found only in the experiment group. CONCLUSION: This study yielded evidence for the potential and beneficial effects of home-based pulmonary rehabilitation program in patients with moderate to severe chronic lung disease. The program could be adequately utilized for improvement of health related quality of life in chronic lung patients.

Metastasis to the primary thyroid carcinoma is extremely rare. We report here a case of colonic adenocarcinoma metastasis to medullary thyroid carcinoma in a 53-yr old man with a history of colon cancer. He showed a nodular lesion, suggesting malignancy in the thyroid gland, in a follow-up examination after colon cancer surgery. Fine needle aspiration biopsy (FNAB) of the thyroid gland showed tumor cell clusters, which was suspected to be medullary thyroid carcinoma (MTC). The patient underwent a total thyroidectomy. Using several specific immunohistochemical stains, the patient was diagnosed with colonic adenocarcinoma metastasis to MTC. To the best of our knowledge, the present patient is the first case of colonic adenocarcinoma metastasizing to MTC. Although tumor-tumor metastasis to primary thyroid carcinoma is very rare, we still should consider metastasis to the thyroid gland, when a patient with a history of other malignancy presents with a new thyroid finding.

Purpose: This study compared the diagnostic performance of the modified Korean Thyroid Imaging Reporting and Data System (K-TIRADS) for thyroid malignancy with three international guidelines. Methods: From June to September 2015, 5,708 thyroid nodules (≥1.0 cm) in 5,081 consecutive patients who underwent thyroid ultrasound (US) at 26 institutions were evaluated. The US features of the thyroid nodules were retrospectively reviewed and classified according to all four guidelines. In the modified K-TIRADS, the biopsy size threshold was changed to 2.0 cm for K-TIRADS 3 and 1.0 or 1.5 cm for K-TIRADS 4 (K-TIRADS1.0cm and K-TIRADS1.5cm, respectively). We compared the diagnostic performance and unnecessary fine-needle aspiration biopsy (FNAB) rates for thyroid malignancy between the modified K-TIRADS and three international guidelines. Results: Of the 5,708 thyroid nodules, 4,597 (80.5%) were benign and 1,111 (19.5%) were malignant. The overall sensitivity was highest for the modified K-TIRADS1.0cm (91.0%), followed by the European (EU)-TIRADS (84.6%), American Association of Clinical Endocrinologists/American College of Endocrinology/Associazione Medici Endocrinologi (AACE/ACE/AME) (80.5%), American College of Radiology (ACR)-TIRADS (76.1%), and modified K-TIRADS1.5cm (76.1%). For large nodules (>2.0 cm), the sensitivity increased to 98.0% in both the modified K-TIRADS1.0cm and K-TIRADS1.5cm. For small nodules (≤2.0 cm), the unnecessary FNAB rate was lowest with the modified K-TIRADS1.5cm (17.6%), followed by the ACR-TIRADS (18.6%), AACE/ACE/AME (19.3%), EU-TIRADS (28.1%), and modified K-TIRADS1.0cm (31.2%). Conclusion The modified K-TIRADS1.5cm can reduce the unnecessary FNAB rate for small nodules (1.0-2.0 cm), while maintaining high sensitivity for detecting malignancies >2.0 cm.

OBJECTIVES: The aim of this study was to explore the changes of bronchoscopic features according to epidemiologic change of lung cancer. METHODS: We performed a retrospective review of the clinical characteristics of 1,139 lung cancer patient who underwent bronchoscopy at Kosin University Hospital from January 2000 to December 2010. RESULTS: The age of patients increased significantly during the last decade (P < 0.001). The most common histological type was adenocarcinoma (38.1%), followed by squamous carcinoma (35.7%) and small cell carcinoma (15.3%). There was an increasing incidence of adenocarcinoma over the time (P < 0.001). Bronchoscopic feature were divided into two classes; central type, peripheral type. The peripheral type was predominant (62.3%). The proportion of peripheral type has been increased in process of time (49.7% vs. 63.7% vs. 73.7%; P < 0.01). Among the major histopathologic type of lung cancer, adenocarcinoma (81.3%) and unclassifiable non-small-cell lung cancer (73.4%), small cell carcinoma (56.9%) were associated with preferential occurrence of peripheral type. Squamous cell carcinoma of the lung more often arised in central type (59%). However, the proportion of peripheral squamous cell carcinoma has been increased. On the subgroup analysis, the median survival time of peripheral type with adenocarcinoma and small cell carcinoma were longer than central type (P < 0.05). CONCLUSIONS: The age of the lung cancer patients at diagnosis was getting older. The most frequent histopathologic type was adenocarcinoma. The proportion of peripheral type lung cancer gradually increased over the time. The survival time of peripheral type lung cancer was longer than central type.

OBJECTIVE: The overexpression of p16(INK4A) is induced by human papillomavirus (HPV) and associated with the carcinogenesis of cervical epithelia. So, immunostaining of p16(INK4A) may be useful biomarker in detecting CIN of cervix uteri in abnormal cervical lesions. The potential of p16(INK4A) as a biomarker for Atypical squamous cells of undetermined significance (ASCUS) examined in liquid-based specimens. METHODS: We collected samples 30 cases of ASCUS in Thinprep(TM) smears between March 2003 and August 2003. 23 control Thinprep(TM) cases were included; 10 negative for intraepithelial lesions, 13 cervical squamous intraepithelial lesions. p16(INK4A) immunochemial staining was performed on 53samples. At the same time, we tested another cervical swabs of patients by the Hybrid Capture II(TM) test. The cut off value was scored positive if it contained above 5 abnormal cells with nuclear and cytoplasmic immunostaining. RESULTS: The results of p16(INK4A) immunochemial staining comparing with one of HC II(TM) showed negative results with low kappa coefficient of 0.034. The sensitivity of p16(INK4A) immunochemial staining were 30.8% and the specificity were 82.4% respectively (p<0.01). p16(INK4A) is a useful marker for the detection of the cervical intraepithelial neoplasia but is not ASCUS. CONCLUSION: Immunostaining of p16(INK4A) is not useful triage test in detecting abnormal lesion of ASCUS in liquid-based specimens.
