批准用于奶牛的抗菌药物分析

我国奶牛养殖规模不断扩大,奶业产值比重逐步提高,给奶牛疫病防治带来巨大压力。奶牛乳房炎及细菌性肺炎等呼吸系统疾病和细菌性肠炎等消化系统疾病最为常见,抗菌药物的使用成为主要防治手段。但抗菌药物的不当使用易使细菌产生耐药性,增加临床治疗的成本和难度,危害我国奶牛产业发展。本文对截至2021年7月我国和美国、英国、日本、欧盟批准用于奶牛的抗菌药物产品进行整理、统计与分析,包括抗菌药物的分类、剂型以及适应证等,旨在为我国奶牛用抗菌药物管理、合理用药和新兽药开发提供参考。     

Mycetoma of the calf

 Actinomycetous infections typically involve either the head and neck or the extremities following a traumatic implantation. Classic clinical associations are draining sinus tracts. This case report describes the pathologic and MR findings of a relatively acute mycetomatous process involving the soft tissues. Pathologic findings in this case included an occasional granule composed of gram positive, thin branching elements. These and other findings were consistent with actinomycetes bacterium infection. The discussion centers around the use of MR, both with and without gadolinium, in evaluating this type of granulomatous infection. Infiltration of the adjacent subcutaneous tissues was easier to appreciate on both the T1-weighted images without gadolinium and the T1-weighted images with gadolinium when compared to the T2-weighted images. Signal characteristics as described in this case report may suggest a granulomatous process.     

肉芽肿性小叶性乳腺炎诊治湖南专家共识（2021版）

肉芽肿性小叶性乳腺炎（GLM）是一种临床上较少见的乳腺慢性炎性疾病,近几年发病率有明显上升趋势。但由于其病因不明、临床医师对该病认识不足,从而导致目前对该病的误诊率较高,特别是治疗不规范、效果欠佳,且病情易反复发作致迁延不愈,俗称“炎症中的癌症”。为此,湖南省健康管理学会乳腺甲状腺健康管理专业委员会、湖南省医学会普通外科学专业委员会乳腺甲状腺外科学组、湖南省预防医学会乳腺疾病防治专业委员会、湖南省中医药和中西结合学会外科专业委员会、湖南乳甲外科联盟5个学术机构,联合省内从事该领域相关专家,就GLM诊治相关内容,多次在线上和线下进行充分研讨,力求不断完善,基本达成共识,共同制定《肉芽肿性小叶性乳腺炎诊治湖南专家共识（2021版）》。     

2009—2018年永靖县妇女乳腺疾病检出情况

目的:了解甘肃省永靖县妇女常见乳腺疾病类型及发生情况,为进一步深入研究和实施干预提供依据。方法:收集2009—2018年在永靖县妇幼保健院进行乳腺检查妇女的相关信息进行回顾性分析。结果:2009—2018年在永靖县妇幼保健院进行乳腺检查者6 265例,共检出乳腺疾病患者2 010例,其中乳腺炎218例,主要集中在40岁以下妇女;积乳269例,多为40岁以下妇女;乳腺导管扩张235例,主要见于25～54岁女性;有乳腺肿块者1 239例,多见于25～54岁妇女;乳腺淋巴炎30例,多为25～54岁女性;乳腺早期发育者19例,主要见于29岁以下女性。检出肿块并确诊为乳腺癌的患者共有75例,确诊率为6.05%,乳腺癌患者主要集中于刘家峡镇、太极镇和盐锅峡镇女性居民中。结论:永靖县妇女的各类乳腺疾病呈现年龄和区域的聚集性,应根据年龄变化和区域特点,确定高危人群和重点区域,做好乳腺相关知识的宣传教育工作,降低各类乳腺疾病的发生率,提高妇女的生活质量。     

T-cell signature cytokines distinguish pulmonary sarcoidosis from pulmonary tuberculosis

Sarcoidosis is a systemic inflammatory disorder characterized by tissue infiltration due to mononuclear phagocytes and lymphocytes and associated noncaseating granuloma formation. Pulmonary sarcoidosis (PS) shares a number of clinical, radiological, and histopathological characteristics with that of pulmonary tuberculosis (PTB). Due to this, clinicians face issues in differentiating between PS and PTB in a substantial number of cases. There is a lack of any specific biomarker that can diagnose PS distinctively from PTB. We compared T-cell-based signature cytokines in patients with PS and PTB. In this study, we proposed a serum biomarker panel consisting of cytokines from cells: T helper (Th) 1 [interferon-gamma (IFN-γ); tumor necrosis factor-alpha (TNF-α)], Th9 [interleukin (IL)-9], Th17 [IL-17], and T regulatory (Treg) [IL-10; transforming growth factor-beta (TGF-β)]. We performed the principal component analysis that demonstrated that our serum cytokine panel has a significant predictive ability to differentiate PS from PTB. Our results could aid clinicians to improve the diagnostic workflow for patients with PS in TB endemic settings where the diagnosis between PS and PTB is often ambiguous.     

Capillaria hepatica parasitism

Capillaria hepatica is rarely encountered in humans, with fewer than 30 documented cases. The clinico-pathological features of capillaria hepatica infection, diagnosed on liver biopsy of a 6-year-old child are discussed. Pathologically, it is characterised by prominent granulomatous lesions in the liver surrounding the eggs, which on cursory examination may be confused withSchistosoma mansoni.     

Treatment of lentigo maligna with combination laser therapy: recurrence at 8 months after initial resolution

This is a case report of an 89‐year‐old woman with a lentigo maligna treated with alexandrite and ruby lasers. The lentigo maligna never completely resolved despite multiple treatments. Marked cosmetic improvement, however, was obtained. No adverse sequelae have occurred.
