A 2-month-old female infant presented with a bluish-black, flat, hairy patch, 1.2cm in diameter, on the posterior aspect of her neck since birth. Histologic sections from the lesion showed numerous diffusely scattered dermal melanocytes throughout the dermis. The histopathologic and clinical findings were not fully oonsistent with any other known dermal melanocytosis. The diagnosis of “hairy blue nevus” was proposed for this unique lesion.

By light and scanning electron microscopy, the morphologies of Korean pubic louse(Phthirus pubis) were described and measured. Especially, electron microscopic structures of palpus, tuft organ, sensilla basiconicum and palpal lobe were reviewed in detail. The variations were obserbed in the number of dorsal setae and the setae of membranous processes of abdomen. And also, the importance of public health and epidemiological aspects was discussed.

We report herein a case of lymphomatoid papulosis in a 23-year-old female who had recurrent erythematous pinhead to pea sized papules and nodules on the both inner thighs and forearms for 4 years. Some lesions showed central hemorrhagic necrosis or scale formation. Individual lesions persisted for several months and showed spontaneous regression leaving pigmentation or depigmented atrophic scar. Histopathologically, there was marked cell infiltration, especially in the dermoepiderrnal junction and perivascular area. Infiltraled cells consisted of sorne ncutrophils and numerous atypical cells that had variable sized and irregular shaped nuclei. Electronmicroscopically, some atypical cells had cerebriform nuclei with marked peripheral condensation of chromatin and cytoplasm contained a few organelles, many polyribosomes and some dense bodies.

Terrys nail(TN) might be causally associated with cirrhosis or other disorders, but his criteria have been proved to be inadequate reflection of systcmic disorders. Modified criteria of Holzberg and Walker were introduced in TN examination in 1984. Using these criteria, fingernails were studied in 444 medical inpatients with chronic systemic diseases at Taegu Catholic Hospital from March 1991 to March 1992. There were 136(30.6%) patients with TN and 308(69.4%) patients without TN, respectively. Ninety-three patients with TN showed a signifiart association with cirrosis(49/86, 57%, p<0.01 by the x-test), congestive heart failure 18/35, 515, p<0.05), and diabetes mellitus(25/51, 49%, p<0.05), and otherwise not;ignificantly associated with chronic renal failure(19%), and cancer(18%). Male and female patients with TN were affected about equally. Age distribution in The patients with TN showed 35(25.8%) the age group from twenty to fortynine and 101(74.2%) in the age group from fifty and above with a mean age of 57.3+14.0, whereas the patients without TN had 178(57.8%), and 130(42.2%), with 47.4+16.9, respectively. The greater part was distributed in the older group(p<0.001 by student t-test), suggestive of an increased risk in older group. The average number of nails affected per patient was tending to be higher in frequency close to the thumb, with an equal frequency in six. Thirty-nine patients(28.7%) had all nails affected. The distal band with was 0.5 to 3.0mm averaging 1.0+0.5mm with no difference, in sex. The distal band was pink in 43(31.6%) of the 136 patients with TN, brown in 62(45.6%) and intermediate in color in 13(22,8%). The results of routine laboratory test such as hemogram, eiythrocyte sedimenation rate, liver enzyme, triglyceride, protein, albumin, blood urea nitrogen and creatinine were statistically insignificant between the patients with and without TN.

BACKGROUND: It has been said that anesthesia and surgery tend to increse 'stress hormone' followed by reduction of GFR and urine flow. We have been noticed a polyuria during mastoidectomy with anesthesia. We hypothesized that a reduction of ADH secretion related to operative procedure might be a cause of a transient polyuria. METHODS: In 41 patients who were in ASA class I, mean arterial pressure (MAP), heart rates (HR), temperature, central venous pressure (CVP) were measured at before induction, just before drilling with irrigation, 30 minutes and 60 minutes after drilling with irrigation, and on arrival in recovery room by groups (room temperatured irrigating fluid and warm fluid were used in group 1 and group 2) during procedures. In 7 of 41, blood samples for antidiuretic hormone (ADH) and plasma osmolalities (Posm) were withdrawn at the same time points. In all patients, fluid were administered with 4 ml/kg/hour throughout the procedures. RESULTS: In group 1, mean urine volume were 5.0 and 6.4 ml/min during anesthesia and drilling with irrigation that was significantly more than in group 2 (3.6 and 4.2 ml/min). In 7 patients, ADH concentration was decreased during surgery compared to pre-induction level, while the Posm were in normal ranges. None of the MAP, HR and CVP showed significant changes. ADH concentrations were not significantly correlated to Posm. CONCLUSIONS: We suggest that a reduction of ADH secretion may have a major role in transient polyuria during mastoidectomy, which might be related to the mechanism that; 1) lowered temperature of hypothalamo-pituitary system by cold irrigating fluid may induce a transient ischemic changes of pituitary gland, 2) absorption of hypoosmolar irrigating fluid to central circulation may reduce central osmotic pressure.
