OBJECTIVES: The purpose of this study was to investigate whether longitudinal changes in positive and negative symptoms affect cognitive functioning in chronic schizophrenia. METHODS: Sixty-eight patients diagnosed with DSM-IV schizophrenia were examined on two occasions over 6 months for symptoms and cognitive changes. Symptoms were measured by PANSS. Cognitive functions were examined for sustained attention, executive function, concentration and attention, and verbal memory and learning using Degraded Stimulus Continuous Performance Test, Wisconsin Card Sorting Test, Digit Span, and Rey Auditory Verbal Learning Test, respectively. Twenty control subjects were assessed to compare the cognitive scores of remitted schizophrenic patients. RESULTS: Patients showed significant improvement in symptoms and all cognitive tests after 6 months treatments. Significant improvements in positive and negative symptoms did not predict improvements in any aspect of cognitive functioning measured. Normal controls performed significantly better than remitted schizophrenic patients on all cognitive tests. The results show no relationship between change in symptoms and change in cognition in chronic schizophrenia. CONCLUSION: We suggest that symptomatic and cognitive impairment may be a distinct construct. These findings highlight the importance of treating cognitive impairment in addition to the clinical symptoms of schizophrenia.

BACKGROUND: Transradial coronary intervention was introduced recently. It has less bleeding and vascular complications and advantage of early ambulation. METHODS: We compared 142 transradial coronary interventions (101 stents, 56 balloon angioplasty and 18 rotablation) with 120 transfemoral interventions in 230 patients from January to August 1998. RESULTS: Overall success rate was not different between two approaches (92% vs 89%), but smaller sized sheath and less amount of contrast agent were required in transradial interventions compared to transfemoral interventions. Conventional guiding catheters which are used in transfemoral approach were used in most cases (94%) of transradial interventions. Judkins left 3.5 (in stead of JL4.0 in femoral approach) and Judkins right 4.0 were the most frequently used guiding catheters in transradial approach. Stent implantation was successfully done in 99 out of 101 lesions (98%) in transradial intervention and 76 out of 78 lesions (97%) in transfemoral intervention. Rotational atherectomy and primary balloon angioplasty or stenting were done successfully in 10 - 20% of the patients in both groups. All procedures were done successfully without any major procedure-related complications (myocardial infarction, death, bypass surgery) or major vascular complications in both groups. During the clinical follow-up of transradial group, punctured arteries showed 10% incidence of radial artery pulse weakness with 3% of pulse loss. CONCLUSION: Transradial approach is useful another feasible route for coronary interventions. The feasibility of primary balloon angioplasty or stenting and rotational atherectomy by transradial approach should be evaluated in the future.

BACKGROUND: Carotid artery stenosis is not infrequently associated with coronary artery disease. However, the technique performing selective carotid angiography is not established during right transradial coronary angiography. We investigated the reliability and safety of selective carotid angiography from the right transradial approach. MATERIALS AND METHODS: Following right transradial coronary angiography, selective carotid angio-graphy was performed using a 5 Fr Simmons-2 catheter in 103 patients (59+/-8 years [range, 18-80], 78 males). Ninety five (92%) patients had significant coronary artery disease. Subclavian and innominate arteries were moderately tortuous in 25 (24%) patients and aortic arch was elongated, more vertically oriented in 20 (19%). After forming a loop in ascending (n=65, 63%) or descending (n=38, 37%) aorta, the catheter was withdrawn and rotated counterclockwise to engage its tip in left carotid artery and innominate artery subsequently. After the catheter tip was adjusted at each ostia of carotid arteries, contrast material was delivered. In 63 (61%) patients, the procedures were performed on outpatient basis. RESULTS: Bilateral selective carotid angiography was successfully performed in 101 (98%) patients. In two patients with severely tortuous subclavian artery, the catheter was not engaged selectively in left carotid artery. The image quality of the angiograms performed by manual injection was determined satisfactory. Significant carotid stenosis was found in 17 (17%) patients. There were no complications, including thromboembolism and arterial dissection. CONCLUSION: Selective carotid angiography can be performed reliably and safely using a 5 Fr Simmons catheter from the right transradial approach. This technique is useful for evaluation of isolated or associated carotid artery stenosis from the right transradial approach.

Tubular apocrine adenoma is a rare benign tumor occuring most often on the scalp. We examined a case of a 69-year-old female who had a well demarcated solid nodule on the scalp. Pathol Microscopically, the tumor was composed of lobules of tubular structures. The tumor lobules were surrounded by a stroma of dense fibrous connective tissue. The tubular structures were usually formed of two rows of epithelial cells. In some areas, the widely dilated tubular structures showed papillary projections into the cavities. Some epithelial cells showed liculoma on decapitation secretion into the cystic structure. Problems of differential diagnosis with other adnexal tumors are briefly discussed.

Sebaceous trichofolliculoma is a variant of trichofolliculoma which occurs in the sebaceous areas rich in follicles and is a relatively rare skin tumor. This tumor is a clinically and histologically easy tumor to recognize that is well differentiated. We examined a case of a consists of a 21-year-old female who had a pedunculated nodule on her scalp. Microscopically, the tumor was large, had a centrally located cavity lined by squamous epithelium and radially arranged sebaceous follicles connected to the cavity. No cytological atypia or recurrence after excision was found.
