A characteristic dermatosis of infancy and childhood has recently been reported as many names, called juvenile plsntar dermatoais, recurrent juvenile eezema of hands and feet, and atopic winter feet in children. However, the clinicsl and epidemiological features of the published cases are strikingly the same The etiology of the diseaee remains unclear. The role of atopy appears to be highly controversial. We have observed 11 patients with juvenile plantar dermatosis and sumrnarized the results as followa: 1. The disease was found mainly in female children (3 boys, 8 girls) between 1 and 18 years old. Duration of the disease ranged from 1 month to 10 years. 2. The lesions occured or were exacerbated dunng the winter in 9 of them. 3. The disease affected symmetrically on the pressure areas of the feet, mainly the forefeet and toes, the lateral margins of the soles, and the heels. Five of our patients also showed the lesions on the hands simultaneously. 4. We have found a high incidence of atopy among the patients or close relative. Nine patients had a personal history of atopy and 5 gatients also had a history of atopy in the first degree relatives. 5. The serum IgE value increased in one of 6 patients determined. From the above clinical findinge, it is evident that juvenile plantar dermatosis is a true localized atopic dermatitis but also a primary irritant contact derrnatitis to which atopics are prone but which may occur in susceptible non-atopics.

We described here a case of hyperkeratosis of the nipple and areola. A 23-year- old woman had a verrucous thickening and brownish discoloration on her right nipple and areola that had been present for 4 yeare. The only symptom was an intermittent mild itching sensation. The patient had no other additioa.al hyperkeratotic conditians. She was not married and had never had a pregnancy. Riopsy spccimen showed papillomatous elongation of the epidermis and edema, of the underlying papillary eonnective tissue. The epidermis was parakeratotic and hyperpigmented, and showed focal intercellular and intracellular edema. The present case seems to be the nevoid form by the Levy-Franckel classification. The world literature was briefly reviewed.

A case of hereditary papulotranslucent acrokeratoderma, a variant of familiaI punctate keratoderma, is presented. A 20-year-old female patient had a five-year history of persistent, asymptomatic, yellowish-white translucent papules and plaques on the thenar and hypothenar eminences and knuckles of both hands, and on the dorsa of proximal interphalangeal joints of both feet. She also had a vitiligo lesion on the left side of the face of 1.5 years duration. Her elder brother also had similar papular skin lesions on both hands and feet. Histologic section of a papule from the right thenar eminence showed marked hyperkeratosis, hypergranulosis, and acanthosis of the epidermis.

Highly specific and sensitive immunoassay method for soluble human recombinant interleukin-6 (hu rlL-6) was established by two different immunization methods. One is conventional method by Freund's adjuvant method and the other is special method which is directly injected to mouse spleen. Among seven established monoclonal antibodies (mAbs), two typical monoclonal antibodies, designated YB3 (IgG1) and NY2 (IgM), were further characterized. These mAbs highly bound to IL-6, however did not show cross reactivity with IL-1B and IL-2. As the results of ELISA inhibition assay and western blotting method, it was further identified that YB3 and NY2 had high binding specificity with IL-6. And the limiting detection amount of rlL-6 for YB3 was 5 ng/ml and for NY2 was 0.5 ng/ml. Furthermore, N-glycosylated human rlL-6 was also bound to YB3 on ELISA. On the other hand YB-3 furtherly recognized N-glycosylated human rlL-6 by sandwich ELISA method. These mAbs may be of use to diagnose the gynecopathy which contains abortion and preterm labor.

We studied the association of nonspecific bronchial hyperresponsiveness with general characteristics, exposure concentration, respiratory symptoms, chest x-ray findings, past histories and pulmonary function. We determined bronchial hyperresponsiveness by methacholine challenge test. And we conducted a respiratory symptom questionnaire and performed spirometry on 111 workers occupationally exposed to isocyanates in various industries. About 21.6% of subjects had bronchial hyperresponsiveness. No significant differences were observed between the hyperresponsive and non-responsive group with respect to age, sex, employment period, height, and smoking histories cough and breathlessness were significantly associated with the bronchial hyperresponsiveness. The hyperresponsive group had more experience of bronchitis and asthma in the past than the non-responsive group. The lower FEV1 and FEV1 % were closely related with bronchial hyperresponsiveness. Bronchial hyperrespoosiveness seems to be associated with some of respiratory symptoms, past histories and pulmonary function parameters in workers exposed to isocyanates.

PURPOSE: To demonstrate the characterization calretinin-immunoreactive displaced amacrine cells in the ganglion cell layer using immunohistochemistry and electron microscopy. METHODS: For immunohistochemistry, sections from guinea pig retina were incubated with mouse monoclonal antibody directed against calretinin. For double label studies, sections were incuated in mixture of mouse monoclonal anti-calretinin or rabbit polyclonal anti-calretinin with following antibodies: goat polyclonal anti-ChAT, rabbit polyclonal anti-GABA, mouse monoclonal anti-GABAA receptor alpha1, beta2/3. Sections were analyzed using Bio-rad Radiance Plus confocal scanning microscope. Stained sections from three guinea pig were observed with transmission electron microscope. RESULTS: Calretinin immunoreactivity was present in displaced amacrine cells and ganglion cells gaving rise to processes ramified in the inner part of the inner plexiform layer in stratum 4. The same stratum was also occupied by the dendrites of ON-cholinergic amacrine cells. Double-labeling demonstrated that dendrites and cell bodies of displaced amacrine cells colocalized with ON-cholinergic amacrine cells and dendrites of ganglion cells directly overlapped with dendrites of ON-cholinergic amacrine cells. The synaptic connectivity was identified by electron microscopy. Ganglion cell dendrites received synaptic input from ON-cholinergic amacrine cell. GABAA receptor beta2/3 subunit bands cofaciculates the dendrites of displaced amacrine cell and ganglion cell that are juxtapose to the alpha1 subunit of GABAA receptor. CONCLUSIONS: These results indicate that ON-cholinergic amacrine cells modulate calretinin-labeled ganglion cell via GABAA receptor beta2/3 in the guinea pig retina.

BACKGROUND: Although there are several methods for evaluating bone quality, Hounsfield units (HU), a standardized computed tomography (CT) attenuation coefficient, provide a useful tool for estimating focal bone mineral density (BMD). The aim of this study is to investigate the HU for evaluating the degree of osteoporosis in greater tuberosity with regard to anchor positioning. METHODS: Forty patients diagnosed as normal on shoulder CT were included and categorized according to age and gender. Axially sectioned CT images were processed to 3-dimensional models containing information about bone quality using Mimics (14.11 platform v14.1.1.1 Materialise). Three-dimensional anchors were simulated and positioned according to 6 regions of interest (ROI) in the greater tuberosity classified using Tingart's system. Mean HU of intra-anchor volumes in the 6 regions was measured. RESULTS: A significant decrease in HU was observed with increasing age (p=0.0001) and menopause (p<0.001). A significant difference in HU was found between male and female groups with males showing the higher values (p=0.0001). HU of proximal areas of ROI was higher than those of distal areas (p<0.005). However, although mean HU of distal posterior ROI showed the lowest values, no statistically significant difference was found between anterior, middle, and posterior regions (p=0.087). CONCLUSION: Mean HU of ROIs provides a tool for preoperative assessment of focal BMD, which is a factor of suture anchor stability and can be used to aid decision-making regarding secure anchor positioning for rotator cuff repair. Our data support that the most secure point is the proximal regions of ROI.
