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.

Nevus cell nevi and melanocytic nevi are much less common in the oral cavity than on the skin. In the oral cavity, the intramucosal(intradermal) nevus is the most common type, followed by the common blue nevus and the compound nevus. We describe a case of a 32-year-old woman who had an intramucosal nevus with pigmented, verrucous surface arising from the gingiva. The lesion had been excised completely and showed no evidence of recurrence.

OBJECTIVE: This study was conducted to determine why rescuers could maintain adequate chest compression depth for longer periods during conventional cardiopulmonary resuscitation (CPR).METHODS: Various CPR parameters, including average compression depth (ACD), average compression rate, average ventilation time (AVT), and rescuers’ heart rates were recorded in real-time when 20 health care providers performed 10 minutes of conventional CPR during a simulation experiment.RESULTS: The ACD was maintained above 50 mm and was not significantly different during 19 consecutive CPR cycles. The average compression rate increased from 114.9±10.0/min (2nd cycle) to 120.1±13.8/min (18th cycle) (P=0.007), and the AVT increased from 8.7±1.5 seconds (3rd cycle) to 10.1±2.6 seconds (18th cycle) (P=0.002). The rescuers’ heart rates also increased gradually for 10 min; however, they increased rapidly and were highest during the ventilation phase. Their heart rates then decreased and were lowest during the early chest compression phases of each CPR cycle. Decreases in heart rates were significant in all CPR cycles (average decrease: 14.5±4.5 beats/min, P<0.001).CONCLUSION: The ACD was maintained adequately during 10 minutes of conventional CPR. However, the AVT increased significantly during the 10-minute period. The rescuers’ heart rates increased and decreased throughout all CPR cycles. These results showed that the ventilation phase might play a role as a resting period and be a reason for the maintenance of adequate chest compression depth for prolonged periods during conventional CPR.

Patients with pixie ear have an attached, tapering, and low-set earlobe. Traditional methods usually describe excision of the caudal portion of the lobule and reattachment in a more superior position. The present report suggests a simplified skin redraping method for correction of pixie ear. The procedure provides easy method to design and perform, which only requires elevation and trimming of the skin. Other ancillary procedures, such as flap design, anchoring, plication, and subdermal fixation, are not required. This method produces satisfactory results. Postoperative scar is invisible because the incision is on the retroauricular region, and the corrected earlobe has a more natural appearance than the repositioned earlobe. Moreover, skin redraping avoids tension, which contributes to minimization of the postoperative scar.

Cranial mononeuropathies, manifesting particulary as opthalmoplegia or facial palsy, are common entities in the dia-betic population. However, sequential multiple cranial neuropathies due to diabetes are much less common. It is often associated with other conditions such as a brain tumor or head trauma. A 61-year-old diabetic man presented with ptosis, opthalmoplegia, and facial palsy which were manifestations of multiple cranial neuropathies involving the left 3rd, 4th, 6th, and 7th cranial nerves throughout five weeks. The pupils were not involved. The neurologic evaluation included a CSF study and a brain MRI with MRA. None of them produced any significant results. Blink reflexes revealed evidence of a left facial nerve lesion. The blood glucose was strictly controlled and steroid therapy was administered. The ptosis of the patientanjx left eyelid improved during treatment and he was discharged after 13 days. In a follow-up examination 3 months after onset, focal neurological deficits including opthalmoplegia and facial palsy on the left side were greatly improved and barely noticeable.

We report a rare case of the idiopathic membranous glomerulonephritis (IMGN) in association with the thin glomerular basement membrane nephropathy (TGBMN) in a 63-year-old female with hematuria. This is the first case reported in Korea. In renal biopsy of this case, direct immunofluorescence demonstrated anti-IgG Ab along the glomerular capillary wall with granular pattern. The basement membrane was thin, about 170-220 nm and small epimembranous electron dense deposits were observed by electron microscopy. As this case, the combination of TGBMN and IMGN is very uncommon because the IMGN is characterized morphologically by diffuse global thickening of the glomerular capillary wall, while the TGBMN is defined as an extreme thinning of the glomerular basement membrane, less than 200 nm. Our case showed no renal function deterioration and benign prognosis as other reports showed.

We report a case of chromoblastomycosis in a 65 year-old woman. She had a 3x4 cm sized, annular, erythematous, plaque with crusts and ulcers on the right lower arm. The lesion had grown slowly for 2 years. In fungal and histopathologic examinations, several muriform cells were found in dermis as well as in scales and crusts on the lesional skin surface. Isolated fungus was identified as Fonsecaea pedrosoi. We treated the patient occlusive dressing of amphotericin B (3%) ointment for 8 weeks and achieved a good response without any evidence of recurrence. We propose that the occlusive dressing therapy of amphotericin B cream is a good modality among the various treatments of small localized chromoblastomycosis.

BACKGROUND: Although a magnetic resonance imaging (MRI) is highly sensitive for changes associated with ischemic stroke, the detection of an acute ischemic lesion is usually impossible within 6 hours of the stroke onset on a conventional MRI. The perfusion MRI is a new imaging technique for diagnosing acute ischemic stroke. We evaluate the clinical usefulness of the perfusion MRI in predicting the final infarct extent in 18 patients with acute middle cerebral artery (MCA) territory ischemic stroke. METHOD: The perfusion MRI was performed within 6 hours after the stroke onset in all patients with a single-section dynamic contrast-enhanced T2*-weighted imaging in conjunction with a conventional routine MRI and MR angiography. Time-concentration curves and cerebral blood volume (CBV) maps were calculated from the dynamic MR imaging data by using numerical integration techniques. We compared findings of CBV maps with infarction on a follow-up CT or MRI. RESULTS: In 14 of 18 patients, the CBV in the occluded MCA territory were decreased. In the remaining 4 patients with a reversible ischemic neurologic deficit (RIND) or transient ischemic attack (TIA), the CBV were increased in 3 and normal in 1. Out of 14 patients with a decreased CBV, two had focal regions of increased CBV within the affected territory, indicating reperfusion hyperemia. The regions of increased or decreased CBV were eventually converted to infarction on follow-up images in all 14 patients. Out of 4 patients with RIND or TIA, one showed focal infarction in centrum semiovale on a follow-up image. CONCLUSIONS: The perfusion MRI was useful for the assessment of hemodynamic change about cerebral perfusion and may predict the extent of final infarction in acute MCA territory ischemic stroke. These results suggest that the perfusion MRI may play an important role in the diagnosis and management of acute ischemic stroke.

PURPOSE: This study was designed to clarify the osseointegration of the titanium screw coated with CMP, in regard to the time schedule, through the characteristic of early osseointegration. MATERIALS AND METHODS: Mechanical, radiological and histomophometric measurements were performed in 28 rabbit tibial proximal metaphyseal cortical bone screws 6, 12, 26 and 52 weeks after surgery for the in vivo comparison of the osseointegration of titanium screws (3.75 mm diameter, 5 mm length) with different surface treatments: CMP coating group, with the sol-gel method (experimental group) and uncoated group (control group). RESULTS: 1. Radiology: There were no differences between the two groups without a radiolucent line or in regard to the time schedule. 2. Histology: There were no differences between the two groups without a fibrous tissue intervening surface or in regard to the time schedule. 3. Torque test: The test results for the CMP coated group were 1.5 times higher than those for the uncoated group, which was statistically meaningful, but there was no difference in regard to the time schedule. CONCLUSION: CMP coating is an option to increase the osseointegration of the titanium screw.
