The purpose of this study was to investigate muscle volume (MV) and strength characteristics of the rotator cuff (supraspinatus, infraspinatus, teres minor, and subscapularis) and deltoid muscles in each shoulder of asymptomatic baseball pitchers. Twelve collegiate baseball pitchers (PG) and ten male students (CG) who never played an overhand sports volunteered to participate in this study. Magnetic resonance imaging (Straits II, Hitachi Medico, 1.5 T) was used to measure the MV of rotator cuff and deltoid muscles in both shoulders of each subject. Since the individual muscles were difficult to identify on MRI scans, the infraspinatus and teres minor were analyzed as one infraspinatus muscle. Shoulder abduction (ABD), external rotation (ER), and internal rotation (IR) strengths were measured each side using a hand-held dynamometer (Power Track II, Jtech Medical Industry) . The MV of deltoid muscle was significantly larger value on the dominant side (DOM) than on the non-dominant side (NDOM) in both the PG and CG groups (p<0.05) . However, no significant differences in the MV of the rotator cuff muscles and the measured shoulder strength (ABD, ER, and IR) were observed between both sides in either group. Similarly, no significant differences in the DOM/NDOM ratio of the muscle volume and the measured shoulder strength were observed between the two groups. These results suggest that the rotator cuff muscle volume and strength does not differ in both sides of the PG, and DOM/NDOM ratios of the rotator cuff muscle volume and strength of the PG does not differ in those of the CG.

We evaluated Immunochromatographic assay kit to screen HBsAg in human serum. When the reference HBsAg was applyed to ICA, HA and EIA kits, the limit of detection for HBsAg were found out to be 4, 2 and 0.25 ng/ml respectively. But ICA kit required 5 minutes to read the result whereas HA and EIA kit more than one hour. The sensitivity was 97% (29 of 30 samples) and the specificity 100% (45 samples) compared with conventional EIA. The ICA kit needs no instrument or machine to perform the test contrary to the conventional methods. Therefore, this rapid and sensitive ICA kit can be used for HBsAg-screening, especially in the emergency room and in the scene of the accident.

Angioleiomyoma(ALM) of the cavernous type is a rare subtype of leiomyomas arising from the smooth muscle of veins. ALM of this type invariably shows clinically and histopathologically distinctive features, compared with the classical solid or venous type. However, no case of ALM of this type has been yet reported in Korea although there have been several reported cases of other types. We herein present the case of a 39-year-old man with a 7-year history of a painless ALM of the cavernous type on his buttock with the histological features of markedly ectatic vascular channels and thin intervascular bundles of smooth muscles.

Mesenteric lymphadenitis due to Yersinia enterocolitica infection is not common in Korea. Although most cases of Yersinia enterocolitica-induced mesenteric adenitis are self limited, cardinal features of Yersinia enterocolitica-induced mesenteric adenitis are so similar to those of acute appendicitis that some of the patients undergo laparotomy with suspected appendicitis. The findings on laparotomy in such patients are usually enlarged mesenteric nodes with a normal or slightly inflamed appendix. Because histologic examination of the removed mesenteric lymph nodes reveals reactive hyperplasia in most cases, it is usually difficult to suspect Yersinia enterocolitica infection on morphology of the resected nodes. But suppurative granulomata of mesenteric lymph nodes, uncommonly encountered in Yersinia enterocolitica infection, strongly suggest yersinial infection. We report a case of mesenteric lymphadenitis in a 10-year-old boy, who underwent laparotomy with suspected acute appendicitis. The removed lymph node showed several suppurative granulomata in the cortex, suggesting yersinial infection. Serologic study confirmed Yersinia enterocolitica serotype O:3 infection.

Objective To quantitatively assess severity of movement disability by analyzing physical activities recorded by an actigraph monitor in patients with neurology disorders.Methods Eighty-one patients with Parkinson' s disease(PD)and 61 patients with acute cerebral infarction(ACI)accompanying impaired upper limb motor function were included in the study.PD patients and ACI patients were treated using the international PD and ACI treatment guidelines,respectively.The patients were asked to wear an Actigraph monitor for 6 days before the treatment in both PD and ACI patient groups and at 24-38 days post-treatment in PD patients or at 28 days post-treatment in ACI patients.The recorded data was analyzed by power-law exponent(PLE)and detrended fluctuation analysis(DFA).Clinically,before and after the treatments,PD patients were evaluated using the conventional Unified Parkinson Disease Rating Scale (UPDRS),and ACI patients were evaluated by assessing upper limb motor function using Fugl-Meyer Assessment(FMA)and Functional Independence Measure(FIM).The correlation of the UPDRS scores with PLE was analyzed in PD patients,and the correlation of FMA or FIM with DFA in ACI patients.Results Both the UPDRS scores and the PLE values in PD patients were improved after the drug administration(UPDRS total:32.8 ± 16.2 and 28.8 ± 14.7,Z =2.080,P =0.038; UPDRS Ⅲ:18.6 ± 8.2 and 15.7±6.8,Z=2.155,P=0.031; PLE:0.98 ±0.25 and 0.82 ±0.21,Z=2.212,P=0.027,before and after the treatment,respectively).There were a linear correlation coefficient of 0.699 between the improvements of total UPDRS scores and the PLE values,and of 0.823 between the UPDRS Ⅲ and the PLE values.FMA,FIM scores and DFA were improved significantly than before treatment(FMA:12.39 ± 8.21 and 30.28 ±7.29,Z=3.016,P =0.004; FIM:8.98 ±7.29 and 13.21 ±7.6,Z =2.282,P=0.038; DFA:0.86 ±0.31 and 0.98 ±0.27,Z =2.360,P =0.036,before and after the treatment,respectively).It also showed linear correlations between the improvements of FMA scores and DFA(r =0.638),and between FIM scores and DFA(r =0.712,both P ＜0.05).There was no correlation between UPDRS scores and DFA values in PD patients,nor between FIM scores or FMA scores and PLE values in ACI patients.Conclusions Actigraph device can be used to monitor patients activity in movement disorders.Analysis of its PLE can provide a quantitative evaluation in PD while its DFA may provide useful specific assessment of impaired upper limb motor function in ACI patients.It can also be used in quantitatively assessing new drug efficacy.

Pellagra is a disease caused by a deficiency of niacin. It is usually found among chronic alcoholics in Korea. Dermatitis, dementia and diarrhea are characteristic symptoms of pellagra. Vibrio sepsis is due to a virulent, gram-negative rod infection caused by Vibrio vulnificus. It is generally acquired in coastal areas near warm water. Underlying disease and initial clinical presentations of pellagra are very similar to that of vibrio sepsis. Herein, we report a case of pellagra that initially mimicked vibrio sepsis.
