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.

The clinical observation was done on 126 patients of Ota's nevus, 113 of whom were seen at Department of Dermatology, Chonnam National University Hospital from January 1973 through July 1983, and 13 of whom were found among 45, 87l male and female students of high school in Kwangju City, Korea. The results obtained were as follows: 1. The incidence of male and female students of Ota's nevus were respectively 0. 013% and 0.043%, with the incidence,as a whole being 0.03%, whereas the frequency of Ota's nevus among the outpatients was 0. 24% with the ratio of male to female being 1: 2. 67. 2. There was only one family of familial occurrence, in which 2 sisters were involved among 5 siblings. 3. Thirty three percent of Ota's nevus showed the onset at birth. 4. According to Tanino's classification, our patients showed that Type II was 41.7% and then Type Ia, III, Ib, and IV being respectively 33. 3%, 16. 7, 4.2, and 4. 2%. 5. Seleral involvement was 54.2%, especially in type III and Type II. 6. The color was increased in 54%, especially Type II by internal and external factors such as fatigue, warm temperature, menstruation and cold temperature. 7. The color intensification was prominent at the age of 10 to 14.

Drug-induced thrombocytopenia and purpura have boon developed by many various agents. Rifampin and Pyrazinamide have been known as bactericidal antituberculous drugs, but, the above side effects have been a problem. Especially, hematologic side effects art fatal to patients occasionally. Rifampin-induced thrombocytopenia and purpura have been well known, also, pyrazinamide-induced thrombocytopenia have been reported. A new quilonone agent Ciprofloxacin, has been commonly used in clinics now, but it's side effects are not known well. So, we report a case of a 23-year-old female with thrombocytopenia and purpura after taking Rifampin, Pyrazinamide, and Ciprofloxacin as antituberculous agents.

PURPOSE: To evaluate the value of dacryoscintigraphy in the assessment of patients with a clinical diagnosis of functional nasolacrimal duct obstruction. MATERIALS AND METHODS: Dacryoscintigraphy was performed in symptomatic 35 lacrimal drainage systems in 18 patients (age range: 37~76, 8 males, 10 females) that were patent on syringing. RESULTS: Abnormalities were detected with dacryoscintigraphy in 75.8% of systems. The positive scintigrams were subdivided into those demonstrating prelacrimal sac delay (31.8%), delay at the lacrimal sac/junction (40.9%), or delay within the duct (27%). CONCLUSION: Dacryoscintigraphy is noninvasive useful technique in the assessment of the functional nasolacrimal duct obstruction and very sensitive at detecting abnormalities in patients with lid laxity caused by senile change and facial nerve palsy.

OBJECTIVES: Dopamine transporter concentrations have been known to decrease in Parkinson's disease(PD). The aim of the present study was to evaluate the correlation between SPECT measurements of [I-123]N-(3-iodopropene-2-yl)-2beta-carbomethoxy-3beta-(4-chlorophenyl) tropane(IPT) as an imaging agent for measuring changes in transporter concentrations with PD. PATIENTS AND METHODS:IPT labelled with 4.87+/-1.29mCi(180.19+/-47.73 MBq) of [I-123] was intravenously injected into 23 patients(age:58+/-12) with PD and three normal controls(NC)(age:37+/-7) as bolus. Brain SPECT were then performed at 1 hour and 2 hours after injection on a double headed camera. The statistical parameters were the contrast ratio of left basal ganglia(BG) and right basal ganglia to occipital cortex(OCC) per milli curies of injected radiotracer at 1 hour and 2 hours. The correlations were evaluated between these parameters and Hoehn-Yahr classification of the patients. RESULTS: The(BG-OCC)/OCC/mCi ratios at 1 hour and 2 hours for PD and NC were 0.14+/-0.07 and 0.27+/-0.07(1 hour) and 0.12+/-0.07 and 0.34+/-0.04(2 hour), respectively. The(BG-OCC)/OCC/mCi ratios of Parkinson's disease were decreased with higher grade of Hoehn-Yahr classification of the patients. The ratio between BG and OCC for PD were clearly separated from NC and may be useful outcome measures for clinical diagnosis. CONCLUSION: The findings suggest that IPT may be a very useful tracer for early diagnosis and treatment of PD and study of dopamine re-uptake site.

An endotracheal tube obstruction causes serious complications, including cardiovascular instability, pneumothorax, pulmonary edema and brain death. A 74 year old woman was scheduled to undergo a laminectomy and instrument fixation due to tuberculosis spondylitis. The patient was intubated with a 7.0 mm reinforced endotracheal tube, and moved into the prone position. At 100 min after the initiation of anesthesia, signs of partial endotracheal obstruction were observed, including high airway pressure and low tidal volume. The signs of an airway obstruction were aggravated as the operation proceeded. Thirty minutes after the sign of a partial obstruction, those of a total endotracheal obstruction were observed. A mucoid impaction in the endotracheal tube was detected using flexible fiberoptic bronchoscopy. After removing this plug, the ventilation of the patient was maintained within normal limits.

Milia en plaque is characterized by multiple milia-like lesions within an erythematous plaque. Milia en plaque is a rarely reported entity which usually appears in the auricular region. We report the case of a 72-year-old woman who presented with milia en plaque on the left arm after NSAIDs injection. This is a rare case because there are no records of Milia en Plaque occurring on an arm in Korea.

PURPOSE: Thallim-201 (201Tl) brain SPECT, which can represent cellular activity of brain lesions, may provide more useful information in differentiating between benign and malignant brain lesions more so than CT or MRI, that merely represents anatomic changes or breakdown of blood brain barrier. We used 201Tl brain SPECT prospectively to evaluate the utility of 201Tl-indices as an indicator of benign or malignant lesions. MATERIALS AND METHODS: We studied 28 patients. There were 13 cases of benign lesions (3: nonspecific benign lesion, 3: meningioma, 2: low grade glioma, 1: tuberculoma, central neurocytoma, hemangioblastoma, radiation necrosis, and choroid plexus papilloma) and 15 cases of malignant lesions (6: glioblastoma multiforme, 5: anaplastic glioma, 2: medulloblastoma, 1: metastasis and lymphoma). In all patients, CT and/or MRI were obtained and then 201Tl brain SPECT was obtained with measuring mean 201Tl index and peak 201Tl index. An unpaired t-test was performed to compare the 201Tl-indices and pathologic diagnoses to evaluate the utility of 201Tl-indices as an indicator of benign or malignant lesions. RESULTS: There were no statistically significant difference in 201Tl-indices between benign and malignant brain lesions (P>0.05). CONCLUSION: These results demonstrated that we could not use 201Tl indices on brain SPECT alone as an indicator of benign or malignant brain lesions.

Cutaneous sinus tract of dental origin usually arises from chronic dental infection. Because many patients with these lesions do not have any complaints of oral symptoms, the lesions are often diagnosed incorrectly and overlooked. We report two cases of cutaneous sinus tract of dental origin. One case on nasolabial fold originated from the maxillary canine periapical abscess. Another case on the mandible originated from the mandibular 2nd premolar periapical abscess. Endodontic root canal therapy resulted in complete healing of the lesions in both cases. Early correct diagnosis and treatment of the lesions can prevent unnecessary and ineffective antibiotic therapy or surgical treatment.
