Gastric candidiasis is an uncommon disorder. It is an opportunistic pathogen in immune compromised individuals, alcoholics, persons treated with broad-spectrum antibiotics, immunosuppressive and chemotherapeutic agents. Besides, the use of drugs that reduce the gastric acid production may be a cause of gastric candidiasis. We experienced a case of gastric candidiasis following advanced gastric adenocarcinoma. A 85-year-old woman was admitted to our hospital because of epigastric soreness. Endoscopic findings revealed a large ulcero-infiltrating mass with yellow exudate at cardia of the stomach, which suggested an advanced gastric cancer. Endoscopic biopsy revealed spores and pseudohyphae infiltrating through the ulcerated stomach wall, diffuse infiltration of tumor cells and abortive tumor glands. After treatment with fluconazole 100 mg daily for 21 days, no evidence of the gastric candidiasis was seen on endoscopic biopsy and pathologic findings. The case is herein reported of gastric candidiasis following advanced gastric adenocarcinoma along with a review of corresponding literature.

Recently, intra-Muscular Stimulation (IMS) therapy is being increasingly used for musculoskeletal pain. This procedure is generally regarded as a safe procedure for the general public. Some cases of iatrogenic pneumothorax caused by acupuncture have been reported in the medical literature. However, a case of an IMS therapy associated pneumothorax has not reported. We experienced two cases of iatrogenic pneumothorax after IMS therapy. A 62 year-old man received IMS therapy on the right shoulder due to posterior neck pain. After IMS therapy, acute dyspnea and chest discomfort developed. The other patient was a 74 year-old woman who also received IMS therapy. This patient experienced a nonproductive cough and acute dyspnea after the treatment. As the popularity of this form of alternative medicine increases, we might expect to see more cases of iatrogenic pneumothorax. Physicians should be aware of the adverse events associated with IMS therapy. (Tuberc Respir Dis 2007;63:444-448)

반지세포암은 과거에 여러 장기에서 보고되어졌으며 위에서 가장 많이 발생하는 것으로 알려져 있다. 특히 폐 조직에서 반지세포가 나올 경우 일반적으로 전이에 의해 발생한 것으로 생각되어 왔다. 하지만 드물게 폐에서 원발성으로 반지세포암이 발생될 수 있음이 보고되었고, 과거에는 부검이나 다른 장기의 병변이 없는 경우 진단하였으나, 최근 보고들에 따르면 종양 세포들의 형태학적 특징과 면역조직화학염색을 통해 폐의 원발성 반지세포암을 진단하는 예가 증가하고 있다. 저자들의 경우도 기관지 내시경을 통한 조직 검사와 면역조직화학염색으로 반지세포암을 진단하였으며 다른 여러 장기를 검사한 결과 전이 가능한 장기들에서 이상 소견을 발견할 수 없어 폐에 발생한 원발성 반지세포암으로 확진하였고, cisplatin과 paclitaxel의 복합 항암화학요법을 시행하였다. Signet ring cell carcinoma (SRCC) is a unique subtype of adenocarcinoma that is characterized by abundant intracellular mucin accumulation. SRCC can arise in various organs, including stomach, colon, breast, bladder, and prostate. SRCC can also arise as a primary lung tumor, but its incidence is low, ranging from 0.14% to 1.9% in the reported series. Therefore, SRCC in the lung is generally believed to be metastatic. But, recent several immunohistochemical studies have demonstrated that thyroid transcription factor-1 (TTF-1), cytokeratins 7 and 20 are specific markers for SRCC arising in the lung. We report a case of pulmonary SRCC with immunohistochemical characterization in a 54-year-old male. Chest X-ray and chest computed tomography (CT) scan showed a homogeneous mass, approximately 3 cm in diameter and subcarinal lymphadenopathy of left perihilar region. The tumor cells were mainly composed of signet-ring cells and strongly demonstrated cytokeratins (7+/20-). The investigations of whole body failed to reveal any other tumor. On the basis of immunohistochemical studies, we concluded that the tumor was SRCC arising in the lung. (Korean J Med 69:S830-S834, 2005)
Analysis of the Impact LEED-NC Criteria on Appraised Unit Land Value

In recent years, LEED-NC (Leadership in Energy and Environmental Design for New Construction) has become one of the most widely adopted environmental certification systems in the United States. However, according to some researchers, the adoption of the LEED-NC is perceived to add to construction cost and duration compared to conventional building standards. Therefore, it is necessary to examine the economic benefits of LEED-NC to consider how it can be applied worldwide. This study focuses on the impact of LEED-NC on the appraised unit value of parcels in San Francisco County based on the number of LEED-NC Public Transportation Access (PTA) qualified buses, light rail and commuter rail stops, distance to the closest bus, light rail and commuter rail stops, zoning class and parcel size. As a population of interest, San Francisco County was chosen since it is known as a region with well-organized transportation systems including bus, light rail and commuter rail systems. According to the correlation results, this study shows that the appraised land value is significantly affected by LEED-NC PTA, and is correlated to a higher appraised unit value of land parcels.

We experienced a case of Ebstein's anomaly prenatally by fetal sonography. Ebstein's anomaly is a rare congenital heart defect characterized by abnormally downward displacement of the septal and posterior leaflets of the tricuspid valve. In the absence of tricuspid regurgitation, this condition may be completely asymptomatic. On the other hand, symptomatic newborns often develop life-threatening congestive heart failure. A 30-year-old multiparous woman was referred for the evaluation of fetal cardiac defect at 26th gestational week from a private clinic. Fetal ultrasonography showed markedly enlarged right atrium and downward displacement of tricuspid valve into the right ventricle. After discussion with the patient, the pregnancy was terminated and Ebstein's anomaly was confirmed by autopsy.

A novel CMOS temperature sensor with binary output is implemented by using fully differential switched-capacitor circuits for resistorless implementation of the temperature sensor core. Temperature sensing is based on the temperature characteristics of the pn diodes implemented by substrate pnp transistors fabricated using standard CMOS processes. The binary outputs are generated by using the charge-balance principle that eliminates the division operation of the PTAT voltage by the bandgap reference voltage. The chip was designed in a MagnaChip 0.35-μm CMOS process, and the designed circuit was verified using Spectre circuit simulations. The verified circuit was laid out in an area of 950 μm×557 μm and is currently under fabrication.
