Management peculiarities of costovertebral hydatidosis

BackgroundCostovertebral hydatidosis is a rarely reported clinical and radiological entity, estimated at less than 1% of thoracic hydatid locations. Its management is still not codified.ObjectiveThe aim of our study was to specify the management peculiarities of costovertebral hydatidosis.MethodsBetween January 2000 and December 2018, 14 patients were managed for costovertebral hydatidosis in a thoracic surgery department.ResultsThe mean age of our patients was 48 years. The history of a prior hydatid disease was found in 7 patients. Imaging features were suggestive in 13 cases. They showed: involvement of the spinal canal (6 cases), of the soft tissues (5 cases) and spinal cord compression (3 cases). Costovertebral resection of the hydatid lesions was complete in 12 cases. Four patients presented postoperative complications.ConclusionCostovertebral hydatid involvement, may threaten the functional and vital prognosis. Therefore, early diagnosis and management are mandatory, before the occurrence of irreversible neurological impairment. Surgical resection remains the treatment of choice and must be complete whenever possible. Relapse is frequent, hence the importance of a regular follow-up.     

大叶山楝中二萜类化学成分及其抗炎活性研究

目的 研究大叶山楝Aphanamixis polystachya枝叶的化学成分及其抗炎活性。方法 采用硅胶、C₁₈反相硅胶、Sephadex LH-20凝胶及MCI等多种柱色谱技术进行分离纯化,根据理化性质结合波谱数据鉴定化合物结构。采用脂多糖（lipopolysaccharide,LPS）诱导的RAW 264.7巨噬细胞炎症模型,对化合物进行抗炎活性评价。结果 从大叶山楝枝叶中分离得到11个二萜类化合物,分别鉴定为 (4S)-4-[(E)-11-(15,15-dimethyl-14-oxo-14,15-dihydrofuran-12-yl)-11,18-dihydroxy-7- methyloct-6-en-5-yl]-3-methyl-1(4H)-furanone（1）、nemoralisin B（2）、aphapolin A（3）、nemoralisin G（4）、nemoralisin J（5）、nemoralisin I（6）、nemoralisin H（7）、nemoralisin D（8）、nemoralisin A（9）、aphanamene B（10）和反式植醇（11）。化合物11对LPS诱导的RAW 264. 7细胞内NO的生成有微弱抑制作用,其半数抑制浓度（median inhibition concentration,IC₅₀）值为428.7 μmol/L。结论 化合物1为新化合物,命名为陵水暗罗素O（nemoralisin O）;化合物3、8和11为首次从大叶山楝中分离得到;化合物11显示出微弱的抗炎活性。

Bilateral central crystalline corneal deposits four years after intacs for myopia

PURPOSE: To report a case of bilateral central crystalline keratopathy in the anterior stroma occurring 4 years after Intacs implantation. METHODS: A 45-year-old woman underwent bilateral uncomplicated Intacs implantation for myopia. The postoperative course was uneventful. However, between 3 and 4 years after surgery, the patient developed central opacifications of the anterior stroma in both eyes, reducing best spectacle-corrected visual acuity. RESULTS: Intacs were explanted. Confocal microscopy, electron microscopy of the explanted ring segments, and microbiology studies were performed. Opacities were still detectable at the slit-lamp microscope up to 8 months after explantation. CONCLUSIONS: This is the first report on central corneal opacifications after Intacs implantation for myopia. The opacities could be the result of chronic metabolic stress or the beginning of lipid-like changes in another more central corneal localization.     

Cutaneous tuberculosis. A review of 38 cases

INTRODUCTION: Cutaneous tuberculosis (CT) represents only 2% of extra-pulmonary locations. This form should be studied because it may indicate visceral forms of tuberculosis. MATERIAL AND PROCEDURES: Retrospective study of patients affected by CT, conducted in the dermatology department of Charles Nicolle Hospital from 1991 to 2002. Tuberculids have been excluded. RESULTS: We have studied 38 cases of CT subdivided on 8 lupus tuberculosis, fourteen scrofuloderma, two warty tuberculosis, one association between lupus tuberculosis and scrofuloderma, twelve BCG specific reactions and one unclassifiable form. The average age of our patients was 43 years. The sex ratio (H/F) was 1,91. Concomitant visceral tuberculosis was discovered in 9 patients. All cases were confirmed by anatomopathologic examination and half of them had a caseous necrosis. CONCLUSIONS: The incidence of cutaneous tuberculosis seems to be increasing in our country: from 3 per 1000 new consultants in our dermatology department between 1970 and 1977 to 0.44 per 1000 new consultants from 1991 to 2002. Our study points out a male predominance in cutaneous tuberculosis. Clinical forms are still dominated by scrofuloderma which is a multibacillary form.
