There have been several reports of more than one type of porokeratosis occurring in the same family or the same individual. We hope to support the view of different phenotypic expressions of a common genetic aberration by describing an additional case of porokeratosis of Mibelli on the perianal area and DSAP on the face, forearms occurring in a 45-year-old man.

PURPOSE: This study was undertaken to increase the knowledge of the intra- and extra-spinal alignments and to help recovery of sagittal alignment in operation by measuring the normal values of the spinal alignment in relation to hip axis as well as those of the thoracic, thoracolumbar junction, lumbar and lumbosacral junction of sagittal alignment and their correlation. MATERIALS AND METHODS: Whole spine standing lateral radiographs were taken in young 100 adults without spinal abnormalities clinically and radiographically. Intraspinal alignment was measured with angles of thoracic kyphosis, lumbar lordosis, maximum thoracic kyphosis, maximum lumbar lordosis, angle of the thoracolumbar junction, sacral inclination, segmental angles and disc angles respectively with special emphasis on lumbar lordosis. Extraspinal alignment was measured with sacropelvic angle, spinopelvic balance and spinal balance in relation to hip axis. Correlations among these parameters were analyzed. RESULTS: Lumbar lordosis and thoracic kyphosis were measured -49 degree(-22 - -79 degree) and 32 degree(6 degree-56 degree), respectively. Slight amount of kyphosis in thoracolumbar junctional area was considered normal. Lumbar lordosis had significant correlation with thoracic kyphosis and sacral inclination. However, there was no correlation between thoracic kyphosis and sacral inclination. Lowest two lumbar segments comprised 71% of total lordosis. Lumbar lordosis usually started at L1-2 and gradually increased at each level caudally to the sacrum. Sacropelvic angle, spinopevlic balance and spinal balance were measured -11 degree(-6 degree - 24 degree), -4 cm (-10 - 2 cm), and -2 cm (-7 - 4 cm) respectively with C7 positioned posterior to hip axis mostly. CONCLUSIONS: There was a wide range of normal sagittal alignment of the thoracic and lumbar spines, and normal values of these alignments were not easily defined. Therefore, normal patterns of sagittal curvature and sagittal balance should be more emphasized.

PACS (Picture Archiving and Communications System) is a computer-based image storage and retrieval system that can store, recall and display medical images rapidly on high resolution workstations. The image acquisition system consists of direct digital interface to computed radiography (CR) system. We reviewed X-rays of 84 patients who had both studies of Dual energy X-ray Absorptiometry (DXA) and AP, lateral views of lumbar vertebrae between January and December of 1995. We tried to verify the clinical implication of pixel values on PACS for DXA by comparing pixel values and bone mineral density (BMD) of the 2nd, 3rd and 4th lumbar vertebrae. They were all female between 44 and 72 years old, average age of 59. Bone mineral density (BMD), represented in DXA of a total of 252 vertebrae were mostly in the range of between 0.228 (22%) and 1.318 (121%). Pixel values of the AP and lateral views of the 2nd, 3rd and 4th vertebrae in the PACS workstation were closely correlated to bone mineral density (p=0.0001). The values of the DXA (bone mineral density and T score) get comparatively lower as the pixel values get smaller. In conclusion, the pixel value on PACS interfaced to CR could be utilized as an easy, speedy and economical tool for screening of osteoporosis.

BACKGROUND: This study was conducted to investigate whether the preoperative nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) was a risk factor for surgical site infections and nosocomial infections in open heart surgery patients. METHODS: From June 10, 2002 to October 30, 2002, data were collected by prospective surveillance carried out by infection control nurses. Nasal swabs were taken from patients (N= 106) on the day before surgery. The swabs were incubated in staphylococcal broth for 24 hours, and then it was incubated on mannitol salt agar for 24 hours. Muller-Hinton agar supplemented with oxacillin (6 microgram/mL) was used to identify MRSA. RESULTS: Among the study patients (N=106), four(4/106, 3.8%) were identified as MRSA carriers and nine (9/103 , 8.7%) developed nosocomial infections, including three patients (3/103 , 2.9%) who had postoperative mediastinitis Preoperative nasal carriage of MRSA was not associated with nosocomial infections nor surgical site infections (P>0.05). However, the length of hospital stay prior to nasal swab or surgery was found to be associated with MRSA carriage (OR=1.108, 95%CI: 1.026-1.197) or nosocomial infections (OR=1.087, 95%CI: 1.017-1.161). Additionally, the patients with nosocomial infections were more likely than those without to stay in the hospital for a longer period after surgery (P<0.00l). CONCLUSION: Preoperative nasal carriage of MRSA by the patient was not identified as a risk factor for surgical site infection and nosocomial infections in open heart surgery.

We identified the early and late prognostic factors of acute myocardial infarction, and evaluated the clinical differences and the prognosis between Q-wave myocardial infarction and non-Q wave myocardial infarction. Total 146 patients who were managed from Jan 1987 to Aug. 1989 at hallym University hospital were evaluated. According to the presence or absence of Q wave on electrocardiogram, the patients were divided into two groups : a Q wave myocardial infarction group(QMI) and a non-Q wave myocardial infarction group (NQMI). Among 146 patients 109 patients(74.7%) had QMI and 37 patients(25.3%) had NQNI. The mean age, male to female ratio and serum cholesterol level were similar in both groups. But peak level of CPK was significantly higher in the QMI group than that in the NQMI group(P<0.01). Left ventricular end-systolic dimension and ratio of left ventricular dimension to wall thickness in the QMI group were significantly higher than that in the NQMI group(P<0.01). There were no significant differences between two groups in the incidences of mortality, postinfarction angina and re-infarction. During the in-hospital period female gender, old age(more than 60 years), Killip class at admission, early reinfarction and a history of hypertension were significant prognostic factors. main causes of death during the in-hospital period were ventricular tachyarrthymia, heart failure and cardiogenic shock. The incidences of mortality, heart failure and post-infarction angina during a mean follow-up period of 14 months (6~30months) were same in the two groups. The late prognostic factors were old age(more than 60 years), Killip class at admission, heart failure occured during follow-up period(P<0.001) and a history of diabetes mellitus(P<0.05). The patients with late postinfarction angina had more dilated left ventricular end-systolic demension(P<0.05) and lower fractional shortening(P<0.01) than those of patients without late postinfraction angina. There were no significant difference in long term survival rate between QMI group and NQMI group. Further prospective study should be performed to clarify the short and long term prognosis in patients with acute myocardial infarction treated by reperfusion.
