Meningioma originates from arachnoid cap cells and is the second most common intracranial tumor; however, it can also be found in an extracranial location. A very rare primary extracranial meningioma without the presence of an intracranial component has also been reported. Primary extracranial meningiomas have been found in the skin, scalp, middle ear, and nasal cavity. A computerized tomography or magnetic resonance imaging scan is necessary to determine the presence or absence of an intracranial meningioma, and a biopsy is essential for diagnosis. We report a case of primary extracranial meningioma located in the forehead skin of a 51-year-old male.

Recent advances in radiological and serological techniques have enabled easier preoperative diagnosis of sparganosis. However, due to scarcity of cases, sparganosis has been often regarded as a disease of other etiologic origin unless the parasite is confirmed in the lesion. We experienced a case of sparganosis mimicking a varicose vein in terms of clinical manifestations and radiological findings. Sparganosis should be included among the list of differential diagnosis with the varicose vein.

Eccrine spiradenoma is a rare adnexal tumor of the skin and its cytomorphology has seldom been described in literature. To evaluate the cytologic features and diagnostic pitfalls of eccrine spiradenoma, we report a case of 33-year-old male whose clinical presentation was a painful subcutaneous mass at the right preauricular area. Fine needle aspirates revealed tight clusters of multilayered, uniform, cuboidal cells arranged around hyalinized perivascular spaces. Some epithelial cells showed tubules or rosette formations. The background showed scattered, naked nuclei. The histologic findings confirmed the eccrine spiradenoma. The recognition of peculiar cytologic features and clinical correlation could be helpful in the diagnosis of skin adnexal tumors.

Pilomatricoma is a well defind and characteristic entity histologically, but this tumor may be encountered during aspiration biopsy of subcutaneous mass, and is, occasionally, confused with other neoplasms, particularly squamous cell carcinoma, basal cell carcinoma, and epidermal inclusion cyst. Recently, we have experienced a case of pilomatricoma diagnosed by aspiration biosy. The smear of the aspirate revealed anucleated "ghost" squamous cells, basaloid or basophilic squamous cells and nucleated squamous cells, which lack nuclear features of malignacy. These findings are consistent with pilomatricoma.

Kimura's disease is a chronic inflammatory condition producing subcutaneous tumor-like nodules mainly head and neck regions. Elevated serum Ig E levels and peripheral blood eosinophilia are common. Kimura's disease represents and aberrant immune reaction to an as yet unknown stimulus. This case presented is 27 year old female whose chief complaint were painful swelling on Rt cheek and temporal area and diagnosed as Kimura's disease. We preformed surgical excision of the mass on Rt. cheek and temporal area and reconstructed with temporal flap and about 100 cc of free fat graft on the defect of Rt. cheek.

A methadone-diazepam interaction study in rats was performed in which conjugated metabolites of methadone were analyzed using deuterated biosynthetic internal standards. Diazepam (5mg/kg) was given to rats through a cannulate djugular vein and a subcutaneous dose of methadone (10mg/kg) was given. Bile was collecte through the cannulate dbile duct over a period of 24 hours. The deuterium label of the internal standards was found to be stable under conditions of the prolonged incubation. There was no significant difference in the excretion of the metabolites between the control and the diazepam treated rats. Feasibility of using biosynthetic internal standards with selected ion monitoring was established for the drug metabolism and kinetic studies.

The auricle is a three-dimensional cartilaginous frame covered with thin overlying skin. Due to its complex features, reconstructing helical rim defects after the excision of an auricular mass is challenging. Shortage of subcutaneous tissue and the presence of a tightly bound epithelium further hamper the primary closure of lateral (anterior) auricular skin defects. We present herein a case in which we used a helical rim advancement flap along with an additional postauricular skin flap. We achieved a satisfactory esthetic result with minimal loss of helical diameter and a low risk of flap necrosis by preserving the vascular network of the flap. This technique is less traumatic and will facilitate faster healing as well as improved patient recovery.

폐경 후 여성에서 골다공증과 비만은 삶의 질적인 면에서 많은 영향을 미친다. 폐경 후 여성은 호르몬의 변화로 골다공증과 비만의 위험이 높아진다. 골다공증과 체중과의 관련성이 알려져 있고 특히 체지방량과의 관련성이 논의되고 있다. 본 연구에서는 폐경 후 여성에서 골밀도 수치에 따라 체지방 중 심장외막지방과 복부피하지방과 비교하여 골밀도 수치 변화가 지방조직과 관련이 있는지 알아보고자 하였다. 내과 및 검진센터를 방문한 폐경 후 여성 중 골밀도검사와 심장초음파를 실시한 160명이 연구대상이었다. 심장외막지방두께는 세 단면의 측정값을 평균하였으며, 골밀도 수치는 L-spine과 대퇴골 경부의 T값을 사용하여 분석하였다. 및 골밀도검사는 진단기준에 맞게 측정하여 연구결과 나이가 증가할수록 골다공증의 위험이 높아지고 체중은 감소할수록 골다공증의 위험이 높아지는 것으로 나타났다(p<0.05). 폐경 후 여성에서 지방조직과 골밀도 수치변화의 연관성을 보기 위한 연구결과에서는 심장외막지방두께의 증가는 골밀도 수치에 음의 상관관계를 보였고(p<0.05), 복부피하지방두께의 증가는 골밀도 수치에 양의 상관관계가 있는 것으로 분석되었다(p<0.05). 즉 지방조직의 침착위치에 따라 골밀도 수치가 미치는 영향이 서로 다른 것으로 나타났다. 폐경기 여성에서 심장외막지방조직의 두께 변화를 정기적으로 검사한다면 골다공증을 미리 예방할 수 있을 것으로 생각된다.

본 연구는 살충제 amitraz의 피하투여 급성독성을 평가하기 위해 0, 2, 10 및 50 mg/kg용량으로 1회 피하투여한 후, 사망률과 일반증상, 체중, 혈액 및 혈청생화학 및 부검소견에 미치는 영향을 평가하였다. 시험결과, 비글 개에 있어서 amitraz의 단회 피하투여는 식욕부진과 침울, 구토, 유루, 운동성감소, 보행실조, 투여부위의 부종, 종괴 및 농양형성, 사지의 부전마비, 횡와위, 빈사, 사망, 체중감소, 투여부위의 근육출혈과 염증, 그리고 간과 신장의 충혈을 유발하는 것으로 나타났다. 반면, 투여 후 14일째에 생존동물의 혈액 및 혈청생화학치에서는 시험물질의 투여와 관련된 어떠한 변화도 인정되지 않았다. 결론적으로 본 시험조건하에서 비글 개에 대한 amitraz의 반수치사량은 22.3 mg/kg (95% 신뢰 한계: 산출되지 않음)이고, 무해용량(no-observed-adverse-effect level)은 2 mg/kg 이하로 사료된다.
