The hair growth of the scalp is influenced by many systemic and local factors. So the study of standard hair growth rate is very important for the diagnosis and treatment of some pathological conditions. That study has not been done well in Korea. The present study was to establish the standard hair growth rate of the scalp of healthy Koreans at different ages. The investigations were carried out on 509 individuals of both sexes whose ages ranged between 2 and 69 years. The subjects were grouped according to 5 age periods. The results of this study were as follows: 1. The mean value of the daily scalp hair growth rate was 0.401+ 0.037mm. 2. The daily hair growth rate of each groups were as follows: under 10 years of age; 0.367+0.032mm, in the teenagers; 0.419,+0. 032mm, in the twenties0.398+0.037mm, in the thirties and fourties; 0.394+0.034mm, above 50 years of age 0.386+029mm. 3. Sex differences of each age groups in the scalp hair growth were not statistically significant.

PURPOSE: To identify clinical and laboratory features of atypical Kawasaki disease(KD), and to develop criteria for early diagnosis of atypical KD patients. METHODS: All patients with KD treated at our hospital from January 1998 to June 2000 were reviewed retrospectively. RESULTS: Among a total of 167 patients, 28(16.8%) were atypical KD of which seven(25%) were infants. Among the five cardinal symptoms, oral mucosal change(96.4%) occurred most frequently, followed by conjuntivitis(57.1%) and rash(46.4%). Most notable laboratory findings were anemia, and increased erythrocyte sedementation rate(ESR) or C-reactive protein(CRP). Coronary artery abnormalities developed in seven(25.8%) atypical KD patients, compared with 14.4% in typical KD patients. We considered oral mucosal change as major criterion, and conjunctivitis, rash, hematocrit <35% and ESR >30 mm/hr or CRP >3.1 mg/dL as minor criteria. Proposed modification in diagnostic criteria for atypical KD include fever of >or=5 days;major criterion+>or=2 minor criteria, or fever of >or=5 days+4 minor criteria. CONCLUSION: The modified diagnostic criteria has yielded a sensitivity 89.3%. Our diagnostic criteria may be used for early diagnosis of atypical KD.

A group of patients with Kawasaki disease (KD) initially present with cervical lymphadenitis or deep neck infection. These unusual KD presentations lead to unnecessary antibiotic therapy or surgical intervention, thereby delaying intravenous immunoglobulin treatment and increasing the risk of coronary artery damage. We present four KD patients whose initial presentations mimicked a retropharyngeal abscess. Nonsuppurative cervical lymphadenitis or suspected neck abscess unresponsive to intravenous antibiotics could signal the possibility of KD.

BACKGROUND AND OBJECTIVES: The pathogenesis of hyponatremia (serum sodium <135 mEq/L) in Kawasaki disease (KD) remains unclear. We investigated the clinical significance of hyponatremia, and the role of interleukin (IL)-6 and IL-1beta in the development of hyponatremia and syndrome of inappropriate antidiuretic hormone secretion (SIADH) in KD. SUBJECTS AND METHODS: Fifty KD patients were prospectively enrolled and analyzed for clinical and laboratory variables according to the presence of hyponatremia or SIADH. RESULTS: Thirteen KD patients (26%) had hyponatremia and 6 of these had SIADH. In patients with hyponatremia, the percentage of neutrophils (% neutrophils), C-reactive protein (CRP), and N-terminal pro-brain natriuretic peptide (NT-proBNP) were higher than in those without hyponatremia, while serum triiodothyronine (T3) and albumin were lower. Patients with hyponatremia had a higher incidence of intravenous immunoglobulin-resistance but this was not statistically significant. No differences existed between patients with and without SIADH with regard to clinical or laboratory variables and the incidence of IVIG-resistance. Serum sodium inversely correlated with % neutrophils, CRP, and NT-proBNP, and positively correlated with T3 and albumin. Serum IL-6 and IL-1beta levels increased in KD patients and were higher in patients with hyponatremia. Plasma antidiuretic hormone increased in patients with SIADH, which tended to positively correlate with IL-6 and IL-1beta levels. CONCLUSION: Hyponatremia occurs in KD patients with severe inflammation, while increased IL-6 and IL-1beta may activate ADH secretion, leading to SIADH and hyponatremia in KD.

OBJECTIVES: To determine the prevalence and related factors of work related musculoskeletal symptoms in hairdressers. METHODS: Informations on general characteristics, job strain, and musculoskeletal symptoms were obtained by a self-administered questionnaire, through adopting NIOSH instrument and JCQ(Job content questionnaire), from 267 hairdressers, between March and May, 2000. RESULTS: The symptom prevalence by NIOSH surveillance criteria in total was high as 94.4%; shoulder (61.0%), neck (59.9%), low back (53.2%), hand and wrist (41.6%), etc. In multiple logistic regression, significant factors affecting the symptoms by body region; job insecurity on neck' gender, alcohol, decision latitude on low back; alcohol on hand and wrist; smoking on thigh and knee,' smoking, decision latitude on ankle and foot; job insecurity on upper back. CONCLUSIONS: Musculoskeletal symptoms of hairdresser were highly prevalent, and associated with job strain and their health habits. This is a basic data of work related musculoskeletal disorders among hairdressers who are not the subjects of occupational health service at the present time in Korea.

PURPOSE: To investigate the influence of 2 phases of short interval intracortical inhibition (SICI) on the cortical silent period (SP). MATERIALS AND METHODS: Single- and paired-pulse transcranial magnetic stimulations (TMSs) at 1 and 2.5ms interstimulus intervals (ISIs) were applied to the left motor cortex in 12 healthy subjects while their right hand muscles were moderately activated. Conditioning stimulation intensity was 90% of the active motor threshold (AMT). Test stimulation intensities were 120, 140, 160, 180, 200, 220, 240, 260% of the AMT and at 100% of the maximal stimulator output, the order of which was arranged randomly. The rectified electromyography area of motor evoked potential (MEP) and duration of the SP were measured off-line using a computerized program. RESULTS: At high-test stimulation intensities, MEP areas were saturated in both single- and paired-pulse stimulations, except that saturated MEPs were smaller for the paired-pulse TMS at 1ms ISI than for the other conditions. As the test stimulation intensity increased, SP was progressively prolonged in both single- and paired-pulse stimulations but was shorter in paired-pulse than single-pulse TMS. Overall, the ratio of SP duration/MEP area was comparable between single- and paired-pulse TMS except for the paired-pulse TMS at 1 ms ISI with a test stimulation intensity at 140-180% of the AMT, in which the ratio was significantly higher than in the single pulse TMS. CONCLUSION: These results suggest that 2 phases of SICI modulate MEP saturation and SP duration differently and provide additional evidence supporting the view that 2 phases of SICI are mediated by different inhibitory mechanisms.
