OBJECTIVE: To evaluate the predictive factors associated with the success of medical abortion by misoprostol monotherapy within 24 hours in the first trimester of pregnancy. METHODS: The records of 228 women with miscarriage up to 11 weeks of gestational age who underwent medical abortion by intravaginal misoprostol monotherapy were reviewed. Success of abortion was defined as complete expulsion of the conceptus without the need for surgical intervention. Outcomes of interest were success of abortion within 24 hours following administration of misoprostol. RESULTS: Among 222 women who continued the process of medical abortion for 24 hours, 209 (94.1%) had a successfully completed abortion. Multivariate logistic regression showed that serum β-human chorionic gonadotropin (β-hCG) above 40,000 mIU/mL is significantly associated with failed medical abortion within 24 hours (odds ratio [OR], 7.13; 95% confidence interval [CI], 1.60–37.32; P=0.011). The area under the receiver operating characteristic curve of β-hCG level associated with successful abortion within 24 hours was 0.705 (95% CI, 0.63–0.77; P=0.007). Previous vaginal delivery seems to be significantly associated with successful abortion within 24 hours on univariate analysis (P=0.037), but the association was lost in multivariate analysis. CONCLUSION: Misoprostol monotherapy has a high success rate for first trimester abortion. Women with serum β-hCG less than 40,000 mIU/mL are likely to achieve a successful abortion within 24 hours after intravaginal administration of misoprostol.

PURPOSE: This study analyzed and evaluated the demographic, clinical, and cytogenetic data [G-banded karyotyping and array-based comparative genomic hybridization (array CGH)] of patients with unexplained developmental delay or intellectual disability at a single Korean institution. MATERIALS AND METHODS: We collected clinical and cytogenetic data based on retrospective charts at Ajou University Medical Center, Suwon, Korea from April 2008 to March 2012. RESULTS: A total of 190 patients were identified. Mean age was 5.1+/-1.87 years. Array CGH yielded abnormal results in 26 of 190 patients (13.7%). Copy number losses were about two-fold more frequent than gains. A total of 61.5% of all patients had copy number losses. The most common deletion disorders included 22q11.2 deletion syndrome, 15q11.2q12 deletion and 18q deletion syndrome. Copy number gains were identified in 34.6% of patients, and common diseases among these included Potocki-Lupski syndrome, 15q11-13 duplication syndrome and duplication 22q. Abnormal karyotype with normal array CGH results was exhibited in 2.6% of patients; theses included balanced translocation (n=2), inversion (n=2) and low-level mosaicism (n=1). Facial abnormalities (p<0.001) and failure to thrive were (p<0.001) also more frequent in the group of patients with abnormal CGH findings. CONCLUSION: Array CGH is a useful diagnostic tool in clinical settings in patients with developmental delay or intellectual disability combined with facial abnormalities or failure to thrive.

The purpose of this study is to investigate the relationship between the self-reported musculoskeletal symptoms and related factors among VDT operators in bank. The subjects were 950 women workers. The characteristics of subjects were 26.6 years of average age, 5.7 years of average VDT use duration and 6.5 hours of daily VDT use time. The results were as follows. The prevalence of self-reported musculoskeletal symptoms more than severe in Likert scale were 51.4%, 43.9% at the shoulder, 38.3%, 31.8% at the lower back, 38.0%, 31.3% at the neck, 31.2%, 25.2% at the upper back, 21.7%, 16.5% at the wrist and 13.6%, 8.8% at the fingers (while on duty, after home-coming). General characteristic variables affecting the musculoskeletal symptoms were married, number of child and daily house-working time. Work-related factors affecting the musculoskeletal symptoms were VDT working career, daily working time, daily VDF use time, VDF use time without rest, daily work-load and regular rest. As the result of the multiple logistic regression analysis, daily working time, daily VDT use time and VDT working career were significant variables accounting for the musculoskeletal symptoms.

Trichophyton(T.) rubrum is an anthropophilic dermatophyte that is found all over the world. It has become one of the most important causative agents in tinea pedis and onychomycosis. But tinea capitis caused by T. rubrum is rare. Tinea capitis is uncommon in an adult. We report a case of tinea capitis caused by T. rubrum in an 81-year-old woman. She presented with localized asymptomatic well-demarcated thick scaly erythematous patches on the fronto-vertex scalp for 6 months. She was diagnosed as seborrheic dermatitis in local clinic and was treated with topical steroid. However, the lesion was not improved and spreading. Culture from scalp lesion of patient was grown on Sabouraud's dextrose agar and showed typical whitish cottony colonies of T. rubrum. She was treated with 200 mg of oral itraconazole daily for 8 weeks. The skin lesions improved 8 weeks after treatment, and recurrence has not been observed.

Langerhans cell granulomatosis(LCG), previously termed 'Histiocytosis-X', is one of the rare disease. LCG is characterized by proliferation of Langerhans cells in a unifocal or multifocal pattern. And LCG may be manifested in a variety of way, ranging from a spontaneously regressing solitary lesion to a multisystem life-threatening disorder. This disease usually involves the bone, lung, skin and lymph node. The most common endocrinologic abnormalities in LCG are diabetes insipidus and growth hormone deficiency. LCG involving the thyroid gland is extremely rare and only a small numbers of cases have been reported worldwide. A 41-year-old diabetic female visited the hospital due to the neck swelling for 3 months and she also complained of polyuria, polydipsia and easy fatigue. LCG involving multiple organs included thyroid gland was diagnosed by high-resolution CT of lung, by characteristic histological findings of the thyroid lesion and by the immunohistochemical staining for S-100 protein and OKT 6(CD la). She is followed at OPD without any medication.

Acute interstitial nephritis is an important cause of acute kidney injury and most often induced by drug therapy. Entecavir is a potent antiviral agent approved for chronic hepatitis B. The antiviral therapy in chronic hepatitis B management is important because it reduces viral replication and liver injury, prevents development of complications, such as liver cirrhosis and hepatocellular carcinoma, and thus improves patient's survival. The advantage of entecavir is its safety profile, particularly in patients with renal dysfunction. Although doses of entecavir are needed to be adjusted for patients with renal dysfunction, there has been no known renal toxicity of the drug itself. Here we report a patient with chronic hepatitis B and normal renal function who developed acute kidney injury due to tubulointerstitial nephritis after 10 months of entecavir therapy. Renal biopsy showed not only acute changes of interstitial nephritis such as marked cortical infiltration with lymphoplasma cells and neutrophils, mesangial matrix expansion, eosinophilic granular casts and degenerative epithelial cells within tubular lumen but also chronic changes, minimal tubular atrophy and interstitial fibrosis. After immunosuppressant therapy with steroids and mycofenolate mofetil, the patient's renal function improved.

Transcatheter arterial radioembolization (TARE) with Yttrium-90 (90Y)-labeled microspheres has an emerging role in treatment of patients with unresectable hepatocellular carcinoma. Although complication of TARE can be minimized by aggressive pre-evaluation angiography and preventive coiling of aberrant vessels, radioembolization-induced gastroduodenal ulcer can be irreversible and can be life-threatening. Treatment of radioembolization-induced gastric ulcer is challenging because there is a few reported cases and no consensus for management. We report a case of severe gastric ulceration with bleeding that eventually required surgery due to aberrant deposition of microspheres after TARE.

Aspergillus tracheobronchitis (AT), an unusual form of invasive pulmonary aspergillosis (IPA), is characterized by pseudomembrane formation, ulcer or obstruction that is predominantly confined to tracheobronchial tree. Hematologic malignancies, neutropenia, solid organ transplantation, chronic corticosteroid therapy and acquired immunodeficiency syndrome (AIDS) are known to be major predisposing conditions. However, since the introduction of highly active antiretroviral therapy, there is only one reported case of AT in AIDS patient. After pandemic of influenza A/H1N1 2009, there are several reports of IPA in patient with influenza and most of them received corticosteroid or immunosuppressive therapy before the development of IPA. We present a 45 year-old AIDS patient with influenza A infection who developed pseudomembranous AT without corticosteroid use or immunosuppressive therapy.
