Cavernous lymphangioma is a benign tumor of lymphatic origin encountering most frequently in young children, and composed of softly fluctuated monolocular or multilocular cystic masses which developed from embryonic outpouching of the venous system. The prevailing site of this tumor Is at the anterolateral neck region particularly posterior triangle, and occasionally axillary, mesentery and spleen etc. Recently, we have experienced one case of left axillary cavernous lymphangioma, which surgically removed successfully and confirmed histopathologically. We want to report one case of left axillary large cavernous lymphangioma with a brief review of the relevant literatures.

Among varieties of the mediastinal tumors, benign developmental cysts [Entergenous cysts] occur about 10% of them. From the primitive foregut, tracheobronchial tree and esophagus develop at 3 weeks of its embryonal age, and bronchogenic cyst arises from accessory or supernumerary lung bud. Usually it remains isolated with surrounding structures, and causes no specific symptoms. But few cases of bronchogenic cysts have fistulous communication with esophagus causing compressive symptoms. We report a case of unusual complicated case of bronchogenic cyst with review of literatures.

The characteristics of slow wave structure employed for backward wave oscillators expected to be a high power microwave source are studied analyytically. The slow wave structure is a sinusoidally corrugated wall waveguide. The waveguide is designed and fabricated by cast aluminun. The dispersion relation and transmitted characteristics for microwaves are measured in the air. There exist literatures on high efficiency of enhanced radiation from backward wave oscillators involving plasma studied experimentally.

Some errors in literatures are pointed out and corrected. A generalization of Ostrowski type inequalities for functions whose derivatives in absolute value are s-convex in the second sense is established. Special cases are discussed.

Ganglion cysts of the cruciate ligaments of the knee are rare and their pathogenesis is uncertain. A few cases of the cyst of the posterior cruciate ligament were reported in the literature. We have arthroscopically treated sucessfully the ganglion cysts of the posterior cruciate ligament through the anteromedial portal. We reported three cases of ganglion cyst of the posterior cruciate ligament with brief of literatures.

Artificial Intelligence literatures have recognized that stock market is a highly unstructured and complex domain so that it is difficult to find knowledge that belongs to that domain. This paper demonstrates that the proposed QCOM can derive global knowledge about stock market on the basis of a set of local knowledge and express it as a digraph representation. In addition, inference mechanism using quantitative causal reasoning can describe the qualitative and quantitative effects of exogenous variables on stock market.

Fungal infections of the spine are relatively uncommon. Moreover, cervical spondylodiscitis due to Candida albicans in non-immunocompromised patient is very rare. We report a case of Candida spondylodiscitis in a 64-year-old woman who complained of neck pain. The clinical feature and treatment option are presented with a review of pertinent literatures.

Hydrocephalus is usually defined as the condition of ventricular dilatation due to the overproduction of cerebrospinal fluid[CSF] or dysfunction of absorption. The pattern of the CSF circulation may change after a cranioplasty secondary to previous decompressive craniectomy for refractory intracranial hypertension after head injury. The effect of the cranioplasty on CSF hydrodynamics has not been explored exactly. We report two cases of acute hydrocephalus developed after cranioplasty and discuss about the clinical importance with review of literatures.

Most of bronchial foreign bodies can be removed by ventilation bronchoscopy through transoral route but sometimes, ventilation bronchoscopy through tracheostomy is helpful procedure. Recently, we have experienced a case of bronchial foreign body which could be easily removed by nasal endoscopy and Blakesley forcep instead of bronchoscopy. So we report this case with a review of literatures.
