Clear cell hidradenoma, generally as an eccrine sweat gland origin, is a fairly uncommon tumor and occurs as a slowly growing, usually solitary nodule. The histological patterns vary from one tumor to another and in different parts of the same tumor. We experienced three cases of clear cell hidradenoma which were diagnosed by the histopathologic examination of the tumor mass removed by surgical excision. Clinical and histopathologic features of each case were reviewed and compared.

We report herein three cases of subcutaneous sarcoidosis without apparent internal lesion. The patients had multiple subcutaneous nodules on the extremities and abdomen. Hyper-gammaglobulinemia, a relative increase of T suppressor cells, and increased serum angiotensin converting enzyme level and skin anergy were observed. Histopathologic findings revealed sarcoidal granulomas involving the subcutaneous fat tissue. The lesions of two cases resolved spontaneously and the other one case required systemic corticosteroid therapy.

The relationship between infective endocarditis and mycotic aneurysm formation appers clear : In about two to ten percent of patients with infective endocarditis harbor septic intracranial aneurysms. But the pathogenesis, natural course and management of these lesions remains controversial. Aggressive medical treatment of the underlying infected cardiac valve or surgical replacement therapy have significantly reduced the morbidity and mortality rates associated with infective endocarditis. Clinical predictors of mycotic aneurysm, especially neurologic prodromes prior to rupture have been ill-defined since most series contain few patients or include patients with infective aneurysms who have no infective endoarditis. Similarly there has been no consensus regarding the indications and timing of cerebral angiography in patients with infective endocarditis. We have experienced a case of cerebral mycotic aneurysm complicated with subarachnoid hemorrhage due to infective endocarditis in a 29 year-old female patient, who admitted to our hospital because of the pain and paralysis of sudden onset in right forearm, which was diagnosed by echocardiography, brain computed tomography and 4-vessel cerebral angiography. The patient died of sudden rupture of mycotic aneurysm in the 7th hospital day despite intensive medical treatment. We report one case of cerebral mycotic aneurysm with a brief of literature.

Many agents for the treatment of osteoporosis are broadly classified as inhibitors of bone resorption and stimulators of bone formation. Many pharmacological derivatives of bisphosphonates are used in the treatment of osteoporosis by inhibiting osteoclast-mediated bone resorption. Although the pamidronate, derivative of bisphosphonates, has a potent antiresorptive activity, there are only a low reports about prevention and treatment of postmenopausal osteoporosis using it. The purpose of this study is to evaluate the changes of bone metabolism and bone mass after pamidronate administration during the early period of estrogen deficiency. Ninty-five Sprague-Dawley rats (weight 233-243 g) were divided into 3 groups. Group 1(n=28) was performed sham operation. Group 2 (n=25) was both ovariectomized and intravenously injected with 0.5 cc normal saline. Group 3 (n=42) was both ovariectomized and intravenously injected with 0.1 mg/kg pamidronate. During the first 8 weeks normal saline or pamidronate was intravenously injected twice a week(q 3 day or q 4 days). After 4 weeks of observation without injection the experiental animals were sacrificed at postoperative 12 weeks. There were statistically significant decrease in the body weight and the weight of uterus in group 1 compared with group 2, 3. There was statistically significant decrease in the bone mass of the spine, proximal femur, proximal tibia in the group 2 compared with group 1, 3. The difference of bone mass between group 1 and 3 was statistically insignificant. Serum osteocalcin and PICP concentration were significantly increased in group 2 and 3 compared with group 1. But there was no statistical significance between group 2 and 3 in serum osteocalcin and PICP concentration. Serum ICTP concentration was significantly decreased in group 1 and 3 compared with group 2, but the difference between group 1 and 3 was insignificant. These results suggests that the administration of the pamidronate during the early period of estrogen deficiency can inhibit bone resorption and prevent trabecular bone loss of the spine, proximal femur and proximal tibia metabolically.

Condyloma lata is one of the cutaneous manifestations of secondary syphilis. They are extremely infectious, moist papules that are commonly seen on patients with secondary syphilis. Condyloma lata commonly affects the intertriginous skin, and especially that of the genitalia, the perianal area and axilla, which all suffer from heat, moisture and friction. However, they are rarely seen on the tongue. A 19-year-old male patient presented with multiple erythematous papules and plaques on the tongue. But he did not have any other cutaneous eruption. Histopathological findings revealed irregular epidermal hyperplasia and perivascular inflammatory cell infiltration with lymphocytes and plasma cells in the dermis. The VDRL and TPHA test were both positive.

OBJECTIVE: Cadaver's sectioned images with high resolution and real color could be used as the source of realistic three-dimensional images. If the sectioned images are registered to a patient's MRIs, three-dimensional images with high resolution and real color that fit the patient, can be produced; the three-dimensional images enable realistic virtual surgery for the patient. The objective of this study was to verify the registration of a cadaver's sectioned images to a patient's head MRIs. METHODS: The sectioned images of the heads of cadaver were associated with segmented images selected at 3 mm intervals. The patient had his head MR scanned at 3 mm intervals; the MRIs were segmented. Software to register the cadaver's sectioned images to the patient's MRIs was developed. On this software, the corresponding dots were identified on both the sectioned images and the MRIs either manually or automatically using segmented images. RESULTS: The registered sectioned images corresponded to the patient's MRIs. Both manual and automatic registrations were satisfied. CONCLUSION: Further study is needed for registering sectioned images to actual patients.

PURPOSE: The aim of this study was to evaluate the efficacy of periprostatic lidocaine injection according to lidocaine dose during transrectal ultrasound-guided prostate biopsy. MATERIALS AND METHODS: The subjects of this study were 92 patients who had undergone transrectal ultrasound-guided 12-core biopsy of the prostate. The patients were randomly assigned to three groups: group 1 (n=31, no lidocaine injection), group 2 (n=30, periprostatic injection of 10 ml 1% lidocaine), and group 3 (n=31, periprostatic injection of 20 ml 1% lidocaine). The patients were assessed for pain by use of a 10-point visual analogue scale (VAS) and for other complications after the procedure. RESULTS: The mean VAS scores of groups 1 through 3 were 0.93+/-0.89, 1.32+/-1.37, and 1.13+/-1.10, respectively. There were no statistically significant differences between the three groups. However, the mean VAS score of the biopsy pain was 5.0+/-1.48, 3.93+/-1.94, and 3.60+/-2.15, in the same groups, respectively, with statistically significant differences between group 1 and the other groups. Patients in groups 2 and 3 reported significantly less biopsy pain than did group 1 patients (p=0.004, 0.021), with no statistically significant difference in VAS score between groups 2 and 3 (p=0.533). With respect to post-biopsy complications, there were no significant differences in the incidence of hematuria, hematospermia, rectal bleeding, or infection among the three groups. CONCLUSIONS: Periprostatic injection of local anesthesia with lidocaine was associated with significantly less pain than in the absence of anesthesia. Furthermore, a 20-ml dose of lidocaine produced no better pain control than did a 10-ml lidocaine dose for prostate biopsy.
