Acrokeratosis verruciformis is a familial disease characterized by indolent papules resembIing flat warts on the backs of the hands and feet with lesser involvement of volar surfaces, wrists, and ankles. A cas of 42 years old female with acrokeratosis verruciformis is reported. The skin lesions of this patient showed numerous rice to pea sized, flat-topped, round or polygonal, warty papules on the dorsal aspects of the hands and feet and also, pitted keratolysis on both volar surface of the hands. The hitologic findings were those of features of acrokeratosis verruciformis, i.e. the epidermis shows marked hyperkeratosis with slight acanthosis and papillomatosis and circumscribed elevations of the epidermis resembling church spires characteristically.

With increasing tendency of incidence and interest for the late onset schzophrenia, concerns about whether this disorder is etiologically or phenomenogically distinctive entity or not have increased also. To clarify the disease entity of the late onset schzophrenia and the role of structural brain changes in its etiology, authors tried to prove following hypothesis : Are there any evidences of structural brain changes in the late-onset schizophrenia? ; If present, are they not different from those of the early-onset schizophrenia or progressive schizophrenia? ; And are they not different from those of senile dementia? Subjects were 6 patients with the late-onset schizophrenia, 6 patients with the early-onset schizophrenia, 6 patients with progressive schizophrenia, 6 patients with Alzheimer's dementia, and 6 controls. We measured regions of interest of the magnetic resonance images by computer assisted planimetry using the AutoCad and digitizer. Our study results may suggest that the third ventricular enlargement and a reversal of normal difference between left and right temporal lobe and left-right difference in posterior lateral ventricle are common brain pathology for all type of schizophrenia including the late onset schzophrenia. And also suggest that brain structural changes of the late onset schizophrenia are related with neurodevelopmental abnormality rather than degenerative change.

We report s case of angiokeratoma of the vulva occuring in a 36-year-old woman. Numerous grayish dark purple papulovesicular lesions, ranging from 0.2 to 2.0mm in size, were observed on the right labium majus. All lesions were excised under local snesthesia after the diagnosis of angio keratoma was made histopathologically. No new lesions appeared during the follow-up period of one year.

8.The Mechanism of Blood Flow Generation during Closed Chest Cardiac Massage: Transesophageal Echocardiographic Monitoring.

The mechanism of forward blood flow during closed chest cardiac massage remains controversial. Two theories have been suggested: the cardiac pump theory and the thoracic pump theory. Case report is presented to illustrate the use of transesophageal echocardiography during cardiopulmonary resuscitation. The findings included right and left ventricular compression, closure of the mitral valve during compression, opening of the mitral valve during the release phase, and atrioventricular regurgitation during compression, indicating a positive ventricular-to-atrial pressure gradient. These findings suggest that direct cardiac compression was the predominant mechanism of forward blood flow during cardiopulmonary resuscitation in this patient. Transesophageal echocardiography offers a new approach for study of the flows and cardiac morphologic features during chest compressions in humans. An understanding of the actual mechanisms involved is necessary if improved cardiopulmonary resuscitative techniques are to be rationally developed for enhancing the outcome of resuscitation.
