Mucosa-associated lymphoid tissue (MALT) lymphoma is one of the most common lymphomas and accounts for about 7% of all newly diagnosed non-Hodgkin's lymphoma (NHL). The clinical course of MALT lymphoma is relatively indolent and, in the majority of cases (50%), the lymphoma arises within the stomach. Primary central nervous system lymphoma (PCNSL), an uncommon variant of extranodal NHL, can affect any part of the neuraxis, including the eyes, brain, leptomeninges, or spinal cord. Herein, we present a rare case of PCNSL, which occurred one year after radiochemotherapy of gastric MALT lymphoma. A 62-year-old man presented with a 3-day history of left facial palsy. One year ago, he underwent antibiotic eradication therapy of Helicobacter pylori, local stomach fractional radiotherapy, and chemotherapy for gastric MALT lymphoma. Magnetic resonance imaging revealed a strong enhancing solid mass in the right frontal lobe. The tumor was completely removed, and the histological diagnosis of PCNSL developing from diffuse large B-cell lymphoma was made. Although elucidating the correlation between the first gastric MALT lymphoma and the second PCNSL seemed difficult, we have postulated and discussed some possible pathogeneses, together with a review of literature.

본 연구는 20대부터 50대까지의 광주, 전남에 거주하는 180명의 건강한 성인 여성을 대상으로 진행되었다. 골대사지표로 골형성지표인 BAP와 OC, 골흡수지표인 NTx를 측정하였으며 골밀도로는 T-score를 이용하였다. 일반적 특징으로 영향 요인으로 연령, 음주, 신체 활동량, 골다공증에 대한 가족력, 폐경, 건강기능성식품 섭취 여부, BMI, 체지방률을 분석하였다. 연령에 따라 비교했을 때 BAP와 OC는 20대가 다른 나이군에 비해 낮았고 음주군은 비음주군에 비해 BAP가 더 높았다. 활동 정도에 따라서는 차이가 없었고 골다공증에 대한 가족력이 있는 군은 골다공증에 대한 가족력이 없는 군에 비해 BAP가 더 높았다. 또한 폐경군은 폐경전군에 비해 BAP가 더 높았으며 건강보조식품 섭취 여부에 따라서는 생화학적 골대사지표나 골밀도의 차이가 없었다. BMI에 따라서는 생화학적 골대사지표 및 골밀도의 차이가 없었지만 체지방률에 따라 분류했을 때는 정상군에 비해 비만군의 BAP가 더 높았고 골밀도는 더 낮았다. 이상의 결과로 보아 노령군, 음주, 골다공증에 대한 가족력, 폐경, 비만이 있는 경우 골형성지표가 증가하였고 특히 비만군에서 골밀도가 낮은 것을 확인하였다. 따라서 골대사지표로 보았을 때, 한국인 여성들은 골 건강을 위해서 나이가 증가함에 따라 음주 및 비만 관리가 중요함을 시사하였다.

Background: Lung cancer is the most common cause of cancer-related death worldwide. The incidence of lung cancer is aproximately 7-8 thousand percent in Turkish women. In this study, we aimed to evaluate the clinical, pathological properties and survival data of female patients with lung cancer who were treated in our center. Materials and Methods: From 2007 to 2012, 50 women with lung cancer were enrolled. Patient data were evaluated retrospectively. Results: The median age was 61 (40-81). Forty patients (80%) were diagnosed with non small cell lung cancer (NSCLC), 10 patients (20%) were small cell carcinoma (SCC). Twelve (24%) patients were smokers and 13 of 16 non-smokers had a history of exposure to asbestos. The most common histologic subtype was adenocarcinoma (46%) and this accounted for 71% in patients with exposure to asbestos. The most common initial Eastern Cooperative Oncology Group (ECOG) performance score was 1 (24 patients, 48%) and initial stage was IV (25 patients, 50%) in the study group. During the median 15 months (1-96 months) followup period: 1 year overall survival (OS) was 68%, 2year overall survival was 36% and the median survival time was 19 months. According to univariate analysis, poor ECOG performance status, advanced stage, anemia and weight loss at time of diagnosis were negative prognostic factors. However, adenocarcinoma sub-type was a positive prognostic factor. Conclusions: In this study NSCLC sub-type, poor ECOG performance score, advanced stage, anemia and weight loss were prognostic factors in Turkish women with lung cancer.

Purpose: The aims of this study were to evaluate the 5-year cumulative survival rate (CSR) of implants placed with guided bone regeneration (GBR) compared to implants placed in native bone, and to identify factors contributing to implant failure in regenerated bone. Methods: This retrospective cohort study included 240 patients who had implant placement either with a GBR procedure (regenerated bone group) or with pristine bone (native bone group). Data on demographic features (age, sex, smoking, and medical history), location of the implant, implant-specific features, and grafting procedures and materials were collected. The 5-year CSRs in both groups were estimated using Kaplan-Meier analysis. Risk factors for implant failure were analyzed with a Cox proportional hazards model. Results: In total, 264 implants in the native bone group and 133 implants in the regenerated bone group were analyzed. The 5-year CSRs were 96.4% in the regenerated bone group and 97.5% in the native bone group, which was not a significant difference. The multivariable analysis confirmed that bone status was not an independent risk factor for implant failure. However, smoking significantly increased the failure rate (hazard ratio, 10.7; P=0.002). Conclusions: The 5-year CSR of implants placed in regenerated bone using GBR was comparable to that of implants placed in native bone. Smoking significantly increased the risk of implant failure in both groups.

Three hundred and twenty-seven patients of 2,046 inguinal hernia cases Primarily repaired at Hanyang University Hospital had the history of incarceration or presented as incarcerated inguinal hernia on admission. Incidence of incarceration of all male hernias was 14.2%(234 patients) and 22.7%(93 patients) of all female cases. Incarceration occurred in 17.3% of all right hernia cases and in 13.7% of all left hernia cases. The incarceration occurred 52.6% of the hernia patients in the first month of life, 27.3% in the first year, 26.7% in the second year and 7.8% after 2 years of age. Strangulated inguinal hernia occurred in 8 patients: five patients had ovaries involved, two patients intestines, and one patient omentum. Emergency operations were performed on 66 patients(20.2%) because incarcerated hernia could not be reduced by taxis. At the time of operation, the hernia sacs were empty in 140 of 327 patients and the remainders contained omentum(50), small intestine (44), appendix and/or cecum(28), sigmoid colon(2), ovary and/or tube(66), and omental cyst(1). An elective hernia repair should be performed promptly after presentation of the hernia, especially before 2 years of life because of high incidence of incarceration. In this study, of 327 incarcerated hernia, 187 patients(57.2%) did not have prior history of incarceration and incarceration developed more than 7 days after hernia onset in 95.6%. If the hernia repairs had been performed within 7 days after hernia onset, about half of the incarceration might have been prevented.

Schwannoma is a benign well-encapsulated tumors arising from the sheath of Schwann cell of the peripheral motors, sensory, and cranial nerves, but not from the optic and olfactory nerves. Since it is relatively common in the head and neck region, it should be included in the differential diagnosis of head and neck tumor. However, reports of laryngeal involvement have rarely appeared in the literature. We have experienced a 50-year old woman and 39-year old woman with history of progressive voice change. We recognized a benign mass at the false cord area with the telelaryngoscope and CT. The tumors were successfully removed by transoral CO2 laser resection without tracheotomy.

Necrotizing fasciitis is an infection of the subcutaneous tissue that results in destruction of the fascia and is disproportionately common in patients with chronic liver disease or diabetes. Necrotizing fasciitis of the head and neck is rare, but has a high fatality rate. A 50-year-old man with a past medical history of diabetes reported a chief complaint of a wound in the posterior neck due to trauma. The wound had grown and was accompanied by pus and redness, and the patient had a fever. When the patient was referred to department of plastic & reconstructive surgery, the sternocleidomastoid muscle, semispinalis capitis muscle, splenius capitis muscle, and trapezius muscles were exposed, and the size of the defect was about 25×20 cm. Dead tissue resection was performed before negative-pressure wound therapy, followed by a split-thickness skin graft (STSG). After a 2-week course of aseptic dressing post-STSG, the patient recovered completely. No postoperative complications were observed for 1 year. Necrotizing fasciitis is a life-threatening, rapidly spreading infection, requiring early diagnosis and active surgical treatment. In addition, broad-spectrum antibiotics are required due to the variety of types of causative bacteria. Broad necrotizing fasciitis of the posterior neck is rare, but can quickly progress into a life-threatening stage.

연구배경: 객혈환자 가운데 20~30%에서는 흉부 X-선사진에 정상소견을 보인다고 하며 이런 환자에서 기관지경검사의 필요성에 대해서는 아직까지 논란이 많다. 또한 객혈환자에서 어떤 방법의 진단적 접근이 유용할 것인지에 대해서는 정확한 지표가 없다. 방법: 1988년 10월부터 1992년 5월까지 객혈을 주소로 경북대학교병윈 호홉기내과를 방문한 환자가운데 흉부 X-선사진 및 객담검사상 이상소견이 없었던 80명을 대상으로 기관지경검사, 기관지조영술 및 고해상전산화 단층촬영 등의 검사를 시행하여 객혈의 원인과 성별, 연령, 흡연력, 출혈의 양과 빈도 등의 임상적 소견과의 관계를 조사하였다. 결과: 1) 남자는 34명, 여자는 46명이었으며 평균연령은 각각 46.7, 41.8세였다. 2) 처음 진찰시 기관지경검사로 진단된 경우는 폐암 3명(3.8%), 전이성 암 1명(1.3%) 그리고 기관지결핵 4명(5.0%)이었다. 3) 폐암의 위험인자는 연령이 50세 이상인 경우와 흡연력이 30인년 이상인 경우였고 30년이상의 흡연력이 표준화 회귀계수가 0.6138로 가장 중요한 인자였다. 4) 기관지경검사에 특이소견이 없었던 72명 가운데 기관지조영술 및 고해상전산화단층촬영상 6명에서 기관지확장증이 있었으며 이가운데 5명에서 재출혈이 있었다. 나머지 66명중 추적관찰이 가능했던 33명 가운데 5명에서 재출혈이 있었으며 이들은 기관지확장증 1명, 결핵 2명 그리고 월경과 관련이 있었던 2명이었다. 결론: 이상의 결과에서 흉부 X-선사진상 정상인 객혈환자는 연령이 50세이상이고 특히 흡연력이 30년이상인 경우는 기관지경검사를 하여 폐암에 대한 조사가 필요하며 그밖의 환자들은 반복적인 객담검사와 더불어 재출혈시에는 선택적으로 기관지조영술이나 고해상전산화단층촬영이 필요할 것으로 생각된다.
