Purpose: This study compared minimally invasive plate osteosynthesis (MIPO) using a single small skin incision and conventional open volar locking plate fixation (OP) for distal radius fracture to identify outcome difference. Materials and Methods: Forty-three patients who underwent MIPO using a single small skin incision or OP for distal radius fractures were evaluated retrospectively. Of the patients, 21 were treated with MIPO using a single small skin incision and 22 with the OP method through the conventional volar approach. The postoperative radiographic results and clinical outcomes at the final follow-up in each group were compared. Results: All patients achieved bone union in the MIPO and OP groups. No significant differences in the bone union time, alignment, range of motion, QuickDASH, or pain score were observed. On the other hand, the size of the incision was significant: 23 mm in the MIPO group and 55 mm in the OP group (p<0.001). Conclusion MIPO technique using a single small incision showed similar satisfactory radiographic and functional outcomes compared to conventional OP for distal radius fractures. The MIPO technique using a single small incision offered advantages, including cosmetic benefits and minimal soft tissue damage, is recommended, particularly in young women and high functional demand patients.

Tuberculosis remains a severe public health problem worldwide. Presently, genotyping is used for conducting epidemiologic and clinical studies on tuberculosis cases. We evaluated the efficacy of the repetitive sequence-based PCR (rep-PCR)-based DiversiLab(TM) system (bioMerieux, France) over the IS6110-restriction fragment length polymorphism analysis for detecting Mycobacterium tuberculosis. In all, 89 clinical M. tuberculosis isolates collected nationwide from Korea were used. The DiversiLab system allocated the 89 isolates to 8 groups with 1 unique isolate when a similarity level of 95% was applied. Seventy-six isolates of the Beijing family and 13 isolates of non-Beijing family strains were irregularly distributed regardless of rep-PCR groups. The DiversiLab system generated a rapid, sensitive, and standardized result. It can be used to conduct molecular epidemiologic studies to identify clinical M. tuberculosis isolates in Korea.

Noroviruses (NoVs) cause major epidemic gastroenteritis in humans. To obtain the molecular epidemiological information on gastroenteritis sporadic cases in Incheon city, Korea, we analyzed the nucleotide sequences of NoV strains detected during 2005~2007. We performed one step RT-PCR amplifying the open reading frame (ORF) 2 (capsid region) followed by semi-nested PCR from the stool samples from acute gastroenteritis patients from 2005 to 2007. Amplicons of the capsid region of norovirus strains were sequenced and analyzed using MegAlign in DNAstar software. Faecal samples were collected from 6,618 acute gastroenteritis patients during the study period. The incidence of NoV infection was about 10.7% (n=708) among patients with acute gastroenteritis and genotypes of the 320 positive samples were determined by sequence analysis. Sequence comparison of NoV strains revealed that 16 genotypes of GII NoV strains were circulated in Incheon city, from 2005 to 2007. Among norovirus strains, the most prevalent genotype GII/4 was most common 69.7% (223 strains), followed by GII/3 17.2% (55 strains), GII/12 4.4% (14 strains), GII/1 2.2% (7 strains), GII/5 1.6% (5 strains), GII/15 1.3% (4 strains) and 0.6% (2 strains) each of GII/9 and GII/16. The GII-3 strains were most frequently detected in Incheon, 2005. From the phylogenetic analysis of NoV strains, we detected 16 genotypes of GII NoV strains during 2005~2007 in Incheon. Our results suggest that various genotypes of human NoV strains in sporadic case of AGE were circulated in Incheon, Korea.

OBJECTIVES: This study was performed to analyze the sociodemographic characteristics of participants in '1998 Korean Depression Screening Day' and to evaluate the results of the screening test. METHODS: By using the survey results of 619 volunteers from 8 hospitals, the authors examined the prevalence of depression detected at the screening test and sociodemographic characteristics and the psychiatric treatment history of respondents. The assessment measure was the Zung Self-Rating Depression Scale. RESULTS: The mean depression score of all participants was 57.5+/-13.8 and it came under mild depression. Of all participants, 69.5% (N=430)had at least mild depressive symptoms, 43.1% (N=267)had at least moderate symptoms, and 18.4% (N=114)had severe symptoms. Never have 56.8% of respondents in the severely depressed range and 63.9% of those in the moderately depressed range had psychiatric treatment. The results suggest that the age group of 29-year-old or younger (relative to 60-year-old or older group)and full-time employment status (relative to unemployment)are protective factors of depression. CONCLUSIONS: By '1998 Korean Depression Screening Day', many depressed patients were detected and their depressive symptoms had statistically significant relationships with some sociodemographic characteristics. The results suggest that the education and screening test programs for depressive illness facilitated by Depression Screening Day are useful to the patients regardless of being under current treatment or not.

Background: We aimed to evaluate the clinicopathological features and biological behaviors of Korean thyroid cancer patients with rare variants of papillary thyroid carcinoma (PTC) to address the ambiguity regarding the prognostic consequences of these variants. Methods: We retrospectively reviewed the medical records of 5,496 patients who underwent thyroid surgery for PTC, between January and December 2012, in nine tertiary hospitals. Rare PTC variants included tall cell (TCV), columnar cell (CCV), diffuse sclerosing (DSV), cribriform-morular (CMV), solid (SV), hobnail, and Warthin-like variants. Recurrence-free survival (RFS) was defined as the time from the date of thyroidectomy until recurrence. Results: Rare variants accounted for 1.1% (n=63) of the PTC patients; with 0.9% TCV, 0.02% CCV, 0.1% DSV, 0.1% CMV, and 0.1% SV. The mean age of patients and primary tumor size were 42.1±13.1 years and 1.3±0.9 cm, respectively. Extrathyroidal extension and cervical lymph node metastasis were observed in 38 (60.3%) and 37 (58.7%) patients, respectively. Ultrasonographic findings revealed typical malignant features in most cases. During a median follow-up of 7 years, 6.3% of patients experienced a locoregional recurrence. The 5-year RFS rates were 71.4% in patients with DSV or SV, 95.9% for TCV, or CCV, and 100% for other variants. DSV emerged an independent risk factor associated with shorter RFS. Conclusion In this multicenter Korean cohort, rare variants accounted for 1.1% of all PTC cases, with TCV being the most frequent subtype. DSV emerged as a significant prognostic factor for RFS.
