Baseline immune activation as a risk factor for the onset of depression during interferon-alpha treatment.

BACKGROUND: Major depression has been associated cross-sectionally with increased cell-mediated immune activation but causality has been difficult to establish. This study prospectively investigated the hypothesis that baseline level of immune activation predicts the development of depression during interferon-alpha (IFN-alpha) treatment. METHODS: Sixteen hepatitis C patients without psychiatric disorder underwent IFN-alpha treatment. Proinflammatory and anti-inflammatory cytokines were determined before starting treatment. Presence of a major depressive disorder (MDD) was assessed at baseline and several times during treatment. RESULTS: Baseline soluble interleukin-2 receptor (sIL-2r), interleukin-6 (IL-6), and interleukin-10 (IL-10) concentrations were significantly increased in the five subjects that developed MDD during treatment compared with those that did not, with standardized effect sizes of 1.08, 1.16, and 1.25, respectively, controlling for marijuana use, cigarette smoking, and baseline level of depressive symptoms. CONCLUSIONS: Results suggest that increased immune activation, rather than an epiphenomenon, is a causal risk factor for the development of MDD.

系统康复治疗对年轻肩关节脱位患者肩关节稳定性的作用

目的对年轻患者肩关节脱位进行系统的康复治疗,以检验系统康复疗法疗效优于单纯固定的假设。方法根据所采用的治疗方法,将43例40岁以下的急性肩关节脱位患者分成实验组23例,对照组20例。实验组患者进行包括关节活动范围锻炼、发展肩胛骨周围肌的肌力训练、发展肩袖肌的肌力、适度的外展、外旋锻炼及耐力训练在内的系统康复治疗。对照组只进行单纯固定后未经系统康复治疗。对两组患者的临床效果进行比较。结果实验组复发率为17%(4/23),对照组复发率为45%(9/20),两组复发率比较差异有显著性意义(χ2=3.866,P<0.05);随访结果显示肩关节ASES评分实验组为90.9±4.87,对照组为75.4±4.94,两组差异有非常显著性意义(t=9.94,P=2.99×10-12<0.01)。结论肩关节脱位年轻患者进行系统的康复锻炼,可以提高患肩的稳定性。     

肿胀法超声抽吸术治疗腋臭83例疗效观察

目的观察肿胀法超声抽吸术治疗液臭的效果,寻找一种治疗腋臭的新方法。方法在腋窝毛发区皮下注入肿胀液80~100ml,经5mm大小切口将超声探头在腋部皮下组织快速移动,直到皮肤发红发热为止,再用负压抽吸被乳化的皮下组织加压包扎。结果83例受术者,术后6~12个月随访,效果良好者76例(91.5%),有效5例(6.25%),无效2例(2.25%)。结论肿胀法超声抽吸术治疗腋臭,操作简单,不留瘢痕,安全有效,是目前治疗腋臭较为理想的方法。     

机械通气治疗小儿急性肺损伤

Dermatofibrosarcoma protuberans: a population-based cancer registry descriptive study of 66 consecutive cases diagnosed between 1982 and 2002

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a rare malignant tumour of the skin, with an estimated incidence of 0.8 to five cases per 1 million people per year. OBJECTIVE: To study epidemiological, immunohistochemical and clinical features, delay in diagnosis, type of treatment and outcome of DFSP from 1982 to 2002. METHODS: Using data from the population-based cancer registry, 66 patients with pathologically proved DFSP were included (fibrosarcomatous DFSP were excluded). Each patient lived in one of the four departments of Franche-Comté (overall population of 1 million people) at the time of diagnosis. The main data sources came from public and private pathology laboratories and medical records. The rules of the International Agency for Research on Cancer were applied. RESULTS: The estimated incidence of DFSP in Franche-Comté was about three new cases per 1 million people per year. Male patients were affected 1.2 times as often as female patients were. The trunk (45%) followed by the proximal extremities (38%) were the most frequent locations. DFSP occurred mainly in young adults between 20 and 39 years of age. Mean age at diagnosis was 43 years, and the mean delay in diagnosis was 10.08 years. Our 66 patients initially underwent a radical local excision. Among them, 27% experienced one or more local recurrences during 9.6 years of follow-up. There was one regional lymph node recurrence without visceral metastases. These recurrences were significantly related to the initial peripheral resection margins. We observed a local recurrence rate of 47% for margins less than 3 cm, vs. only 7% for margins ranging from 3 to 5 cm [P=0.004; OR=0.229 (95%, CI=0.103-0.510)]. The mean time to a first local recurrence was 2.65 years. Nevertheless, there was no death due to the DFSP course at the end of the follow-up, and the final outcome was favourable. CONCLUSION: Our study emphasizes the importance of wide local excision with margins of at least 3 cm in order to prevent local recurrence. However, the recent development of inhibitors of signal transduction by the PDGFB pathway should soon modify the surgical strategy, which is often too mutilating.
