Focal acral hyperkeratosis is clinically identical to acrokeratoelastoidosis but histologically lacks the elastorrhexis which is a feature of acrokeratoelastoidosis. We present a case of focal acral hyperkeratosis in a 50 year old woman. About 20 years ago, a few pinhead sized papules developed on radial side of index fingers. Thereafter size and number of papules have been gradually increased to cover entire hands sparing palms and dorsa of feet. The histopathologic study showed characteristic findings of focal acral hyperkeratosis. After treatment with etretinate, the size and thickness of lesions were reduced.

Vesicles and bullae are the primary lesions in many diseases. The histologic classification of bullous disorders is based on the level in the skin on which that cleavage developed. We report a 44-year-old man with vitiligo at dorsum of hand who has experienced spontanous bullae at recipient site after epidermal graft for the treatment of vitiligo. Histopathologic examination revealed a subepidermal bullae and moderate lymphocytes and eosinophil infiltration in the dermis. Direct immunofluorescence test was negative. There was a change of CD4/CD8 ratio in immunohistochemical staining for CD4 & CD8 monoclonal antibody. There were no clinical signs of infection and drug eruption, and friction did not seem to have been a contributing factor.

Study objectives: To identify the value of symptoms in head trauma patients with mental status requiring a head CT scan. Method: A retrospective study was performed at an emergency center over & months period. Patients(age ? 7) were enrolled if they presented with a Glasgow Coma Scale score of 15 and underwent head CT after head trauma. The symptoms and signs were recorded in the entry forms prior to head CT. The symptoms found in the patients with normal CT were compared with those in abnormal CT showing intracranial injuries. Results: Among the 168 patients, traumatic intracranial abnormality was identified in 34(20.2%) by CT. Skull fracture was identified in 8(4.8%) in normal CT, 17(10.1%) in abnormal CT group by simple X-ray and CT. In the normal CT group without skull fracture, 65(52.0%) had headache, 61(48.8%) had loss of consciousness(LOC), 43(34.4%) had vomiting, 24(19.2%) had nausea, 7(5.6%) had dizziness. In the abnormal CT group without skull fracture, 14(77.8%) had headache, 9(50.0%) had LOC, 9(50.0%) had vomiting, 2(11.1%) had nausea, 2(11.1%) had dizziness. The patients with headache were significantly more common in the abnormal CT group. Conclusion : A head required in alert head trauma patients with any symptoms and signs of intracranial injuries, especially with headache.

One hundred patients with hyperventilation syndrome presenting to emergency department(ED) were studied. Those were diagnosed on clinical basis by emergency medical physician. The male to female ratio was 15:85. In monthly distribution, the numbers of patients were increased during the two months, June and July. The 41% of patients visited the emergency center from 9:00 p.m. to 3:00 a.m.. The most common predisposing factors were the domestic problems, especially those between husband and wife(37%). Presenting complaints were dyspnea(34), paresthesia(30), muscle spasm(24), dizziness(6) and palpitation(6 patients). The initial examination of the patients in the ED were as follows, systolic blood pressure(134±7.15mmHg), heart rate(87.67±14.34/minute), respiratory rate(22.21±3.34/minute) and body temperature(36.61±0.31℃, n=98). Arterial blood gas analysis showed alkalemia(pH 7.51±0.09) and hypocapnia(PCO2 26.67±8.30mmHg). After emergency cares, including carbone dioxide re-breathing and antianxietics, most of the symptoms were disappeared. The mean duration of stay in ED was 3.27±0.23 hours. The most important considerations in diagnosis of hyperventilation syndrome was the patients's history and the effective management was carbon dioxide rebreathing for a few minutes and antianxietics.
