This paper reports a case of testicular synovial sarcoma with molecular genetic analysis.A 24-year-old male presented with painless scrotal mass.Ultrasonography showed a heterogeneous mass of 66 mm×34 mm in size involving the inguinal region.Histological examination of a surgical biopsy showed a gradeⅢmonophasic growth pattern of spindle cell proliferation.Immunohistochemical analyses indicated positive staining for pancytokeratine and epithelial membrane antigen.Cytogenetic analysis showed the presence of CYT-SSX1 mutation,and CT scan showed non-specific pleural micro-nodules with a size of 7.5 mm.The patient had an extended left orchidectomy but was lost to follow-up for 1 year.A local recurrent scrotal mass of 32 mm×25 mm,multiple inguinal lymph nodes,and increased pleural nodules,which were confirmed by histological examination,were treated with three cycles of adriamycine and ifosfamide chemotherapy,surgical resection,and radiotherapy with complete response.After 3 months,the patient developed local recurrence and pulmonary metastases that did not respond to second-line chemotherapy based on gemcitabine and paclitaxel.The patient had dyspnea at the time of this writing and chest pain,and is under third-line chemotherapy based on Deticene after 30 months of following up.This patient died on November 16,2012 after a resperatory failure and malignant plural effusion. Synovial sarcoma should be considered in the differential diagnosis of soft tissue tumor and it should be aggressively treated to improve prognosis.Although our patient has shown numerous factors of bad prognosis,he has had a relatively long survival time. 相似文献

Allopurinol hypersensitivity syndrome (AHS) is a severe drug reaction. It is characterized by rash, fever, and internal organ involvement. It may present in different clinical forms. We present a case of acute generalized exanthematous pustulosis occurring as a manifestation of AHS.KEY WORDS: Allopurinol, hypersensitivity syndrome, pustulosis 相似文献

Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disease of motile cilia. Even though PCD is widely studied, North‐African patients have been rarely explored. In this study, we aim at confirming the clinical diagnosis and explore the genetic spectrum of PCD in a cohort of Tunisian patients. Forty clinically diagnosed patients with PCD belonging to 34 families were recruited from Tunisian pediatric departments. In each proband, targeted capture PCD panel sequencing of the 40 PCD genes was performed. PCD panel sequencing identified bi‐allelic mutations in 82% of the families in eight PCD genes. Remarkably, 23.5% of patients carried the same c.2190del CCDC39 mutation. Single nucleotide polymorphism profiling in six unrelated patients carrying this mutation has revealed a founder effect in North‐African patients. This mutation is estimated to date back at least 1,400–1,750 years ago. The identification of this major allele allowed us to suggest a cost‐effective genetic diagnostic strategy in North‐African patients with PCD. 相似文献

A new actinomycete strain, designated US80 and producing antimicrobial activities against Gram-positive and Gram-negative bacteria and fungi, was isolated from Tunisian oasis soil. Cultural characteristic studies strongly suggested that this strain belongs to the genus Streptomyces. The nucleotide sequence of the 16S rRNA gene (1517 pb) of Streptomyces sp. strain US80 exhibited close similarity (97-98%) with other Streptomyces 16S rRNA genes. Similarity of 98% was obtained with the 16S rRNA gene of Streptomyces roseoflavus, which produces the aminoglycoside antibiotic flavomycin. Study of the influence of different nutritional compounds on production of bioactive molecules showed that the highest antimicrobial activities were obtained when glucose at 1% (w/v) was used as sole carbon source in the presence of magnesium. Extraction of fermentation broth of Streptomyces sp. strain US80 and various separation and purification steps led to isolation of three pure active molecules. The chemical structure of these three compounds, named irumamycin (1a), X-14952B (1b) and 17-hydroxy-venturicidin A (1c), was established on the basis on their IR, ESI-MS, 1H and 13C/APT NMR data and by comparison with reference data from the literature. 相似文献

Herpes simplex virus type 1 (HSV-1) is a ubiquitously occurring pathogen that infects humans early in childhood. The virus persists as a latent infection in dorsal root ganglia, especially of the trigeminal nerve, and frequently becomes reactivated in humans under conditions of stress. Monocytic cells constitute an important component of the innate and adaptive immune responses. We show here for the first time that HSV-1 stimulates human FasL promoter and induces de novo expression of FasL on the surface of human monocytic cells, including monocytes and macrophages. This virus-induced FasL expression causes death of monocytic cells growing in suspension, but not in monolayers (e.g., macrophages). The addition of a broad-spectrum caspase inhibitor, as well as anti-FasL antibodies, reduced cell death but increased viral replication in the virus-infected cell cultures. We also show here for the first time that the virus-induced de novo expression of FasL on the cell surface acts as an immune evasion mechanism by causing the death of interacting human CD4+ T cells, CD8+ T cells, and natural killer (NK) cells. Our study provides novel insights on FasL expression and cell death in HSV-infected human monocytic cells and their impact on interacting immune cells. 相似文献

Neonatal diabetes mellitus is a rare entity defined as hyperglycaemia occurring within the first 3 months of life that lasts for at least 2 weeks and requiring insulin therapy for unforeseeable duration. We report the case of a full-term female infant with permanent neonatal diabetes mellitus, stemming from consanguineous parents, born with severe intra-uterine growth retardation and birth weight of 1400 g. The patient presented on the 15th day of life a severe dehydration with a fever and ponderal loss of 14 %. The biology showed hyperglycaemia to 15 mmol/L, moderate metabolic acidosis, glucosuria and ketonuria. The diagnosis of neonatal diabetes mellitus was reserved, justifying its stake under insulin. Etiologic investigation showed a type HLA-DR4/DR8; anti-insulin antibodies were weakly positive, Langerhans islet cell and anti-GAD antibodies were negative. Abdominal magnetic resonance imaging scans, karyotype, molecular biology and chromatography of amino and organic acids did not show any abnormalities. During the first 2 years of age, the patient presented a big instability of glycaemia having required several hospitalizations. After 12 years of age, the patient is still under insulin with a satisfactory glycaemia balance and her growth is normal. Besides, she presents a microcephaly with a spastic walking. The search of neonatal diabetes mellitus must be systematic in front of any fetal hypotrophy allowing a premature coverage and a good prognosis. 相似文献
