Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and another name for it is apocrine cystadenoma. A 48-year-old female patient had a solitary, translucent red-brownish cystic nodule, 10 × 6 × 7mm in size, on the periorbital area of her left eye. The lesion had enlarged very slowly for 25 years. We excised the lesion and identified it as apocrine hidrocystoma. This is a case of apocrine hidrocystoma with typical clinical and histopathological findings.

In acupuncture practice of animals, preanesthetics sometimes are needed. The purpose of this study was to select the ideal chemical restraint at acupuncture for gastric motility. Nine healthy mixed breed dogs weighed 10-21 kg and aged 1-3 years old were used in this study. Two EMG surface electrodes were placed between the seromuscular and the mucosal layer of pylorus. Twenty minutes after feeding normal gastric motility was recorded for 60 minutes using physiograph (Narco-Biosystem). Then preanesthetic treated-gastric motility was observed for 30 minutes. Preanesthetics used were xylazine, diazepam, and acepromazine. Acupuncture needles were inserted to BL-21 (Wei-Yu) acupoint, and then changes of gastric motility were recorded for 60 minutes. The gastric motility following xylazine administration (1 mg/kg, IV) was markedly decreased. BL-21 (Wei-Yu) acupoints stimulation did not alter xylazine-induced depression of gastric motility. The diazepam (1 mg/kg IV) treated-gastric motility was increased mildly 20 minutes after drug administration. BL-21 (Wei-Yu) acupoint stimulation after diazepam administration enhanced gastric motility significantly. The gastric motility following acepromazine (0.3 mg/kg, IM) administration was not changed compared with normal gastric motility. Application of traditional acupuncture at BL-21 (Wei-Yu) significantly increased the gastric motility. Based on these results, acepromazine and diazepam could be acceptable chemical restraints for acupuncture therapy of gastric motility, but xylazine couldn't be.

BACKGROUND: Laser resurfacing has beneficial effects for the treatment of several skin conditions. Recently, the pulsed erbium:YAG laser has been shown to be a highly effective treatment for several kinds of pitted facial scars. OBJECTIVE: The purpose of this study was to assess the efficacy and safety of pulsed erbium:YAG laser skin resurfacing at the setting of low or high energy for pitted acne scars. METHODS: 65 patients with pitted acne scars were included in this study. All patients had skin types III or IV. All patients were instructed to use tretinoin cream 0.05% nightly for 2-4 weeks prior to the laser treatment. The pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 mJ/pulse, 3.5-5 W in 45 patients and 1,000 mJ/pulse, 7-10 W in 20 patients was used. Two weeks after laser treatment, topical application of hydroquinone 4%, tretinoin 0.05%, and hydrocortisone 1% cream was recommended for 2-4 weeks. Facial photographs were obtained at baseline and 2 week intervals postoperatively. The results of treatment were evaluated for the changes of skin texture and color at 1 month, 3 months, and 6 months. RESULTS: In 45 cases treated with 500 mJ/pulse energy, pitted acne scars were improved about 46.7 % on average and no erythema and postinflammatory hyperpigmentation was observed after 6 months. In 20 cases treated with 1,000 mJ/pulse energy, pitted acne scars were improved about 64% on average and erythema in two patients and postinflammatory hyperpigmentation in one patient were observed after 6 months. CONCLUSION: The results of laser treatment for pitted facial acne scars at the setting of high energy are better than those of laser treatment at the setting of low energy.

PURPOSE: This study was conducted to compare the PET and CT findings for patients with a pulmonary lymphangitic metastasis. MATERIALS AND METHODS: We retrospectively reviewed the PET and CT findings of seven patients diagnosed with a pulmonary lymphangitic metastasis between May 2005 and May 2007. RESULTS: All patients had interstitial thickening, as seen on a CT scan, while the PET scans showed abnormal findings in only three patients. In these three patients, one patient had interlobular septal thickening of more than 10, another patient had interlobular septal thickening of more than 5 but less than 10, and another patient had interlobular septal thickening of less than 5. All of the patients had bronchovascular bundle thickening. However, among the four patients that had normal FDG uptake, no patient had interlobular septal thickening of more than 10, two of the patients had interlobular septal thickening of more than 5 but less than 10, and the remaining patients had interlobular septal thickening of less than 5. Only two of the patients had bronchovascular bundle thickening. CONCLUSION: All patients with pulmonary lymphangitic metastasis have typical CT findings, but some of the patients had FDG uptake, as seen in the PET scans. Thus, CT is a more useful modality for diagnosis for pulmonary lymphangitic metastases.

The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.

A retrospective review was undertaken of 5 pediatric cases of posterior urethral valve with vesicoureteral reflux. The clinical data were summarized as follows : 1. At the time of diagnosis, patient age was recorded as 2 months, 3, 4, 13, and 14 years. Three cases presented with high fever, one with urinary dribbling and one with acute epididymitis. 2. Voiding cystourethrogram was abnormal in all cases, showing thickened, trabeculated bladder wall, dilatation of posterior urethra and vesicoureteral reflux. Vesicoureteral reflux was bilateral in 3 cases, unilateral in 2 cases and its degree was grade R-V/V in 8 renal units, grade E/V in one renal unit. 3. Initially transurethral valve ablation was performed in all cases, of which 2 had concomitant antireflux surgery and 3 had delayed ureteral reconstruction between one and 11 months after valve ablation. 4. Follow up duration was between 13 and 53months. In 4 cases, reflux disappeared and the pyelographic appearance markedly improved as regards pelvocalyceal and ureteral dilatation with improvement of general status at followup. But, in one case that had demonstrated bilateral high grade vesicoureteral reflux with sever ureteral dilatation and poor renal function, voiding symptom and radiologic appearance improved but left vesicoureteral reflux persisted by 13 months after reconstructive surgery.
