Nosocomial infection occurs in the hospital and other medical offices and expresses any disease, that affects the patient due to hospital admission or the received care, the activity of the medical personnel, no matter that symptoms appear or not in the hospital or outside. In the performed study we proposed to investigate the implementation level of the measures of nosocomial infections prophylaxis in dental office. The study consisted in a transversal epidemiologic inquiry through a specific questionnaire applying in a sample of 50 patients treated for dental diseases in the dental office. The items refer to the implementation level of the prophylaxis measures in the dental office. The obtained results revealed a proper patients' addressing at dental office and some deficiencies of the personnel medical activity in dental office, such as : does not wear the surgery gloves and mask, does not use the salvo vacuum for patients protection. Also, we find out a deficient medical education referring to hygiene conditions in dental office. In conclusion, there are deficiencies of the prophylaxis measures in dental office.  相似文献

We report a case of a 16-year-old girl with a left renal tumor discovered by her family practitioner.On physical examination the patient had a painless abdominal mass, located in the upper medium portion of the abdomen on the left side with a voussure of the abdominal wall. Ultrasound and abdominal pelvic CAT scan revealed a large heterogeneous mass with calcifications in the inferior portion of the left kidney.We made touch-imprint cytological preparations of the biopsy fragments, obtained under ultrasound guidance. Cytological analysis revealed highly cellular smears with malignant cells arranged in large clusters or rarely isolated, sometimes surrounding hyaline nodules with numerous psammoma bodies. After May-Grünwald-Giemsa staining, cells displayed moderately irregular nuclei with an abundant and pale basophilic cytoplasm with well-defined borders and a finely granular texture. The diagnosis of a special type of renal cell carcinoma was suspected, and was then confirmed after examination of the biopsy sample and the corresponding surgical specimen.The histomorphologic features were those of a renal cell carcinoma associated with an Xp11.2 translocation. Immunohistochemistry revealed this translocation by showing nuclear positivity in tumor cells for an antibody raised against the TFE3 protein.The clinical outcome was marked several months later by metastases in lymph nodes, bone, lung, and adrenal gland as well as a local recurrence.  相似文献

Cytogenetic studies were performed in 120 patients with de novo myelodysplastic syndrome (MDS) classified according to FAB criteria. Twenty-eight patients had refractory anemia (RA), 14 had refractory anemia with ring sideroblasts (RARS), 45 had refractory anemia with blast excess (RAEB), 19 had refractory anemia with blast excess in transformation (RAEB-t), and 14 had chronic myelomonocytic leukemia (CMMoL). Fifty patients (42%) had clonal chromosome anomalies at initial analysis. The most common cytogenetic anomalies were: 5q- (11 patients), trisomy 8 (nine patients), -7/7q- (6 patients), 12p- (five patients), followed by structural anomalies of chromosome 17 (four patients), and loss of Y chromosome (three patients). The prognostic value of chromosome anomalies was examined by comparison of the significance of single chromosome anomalies (34 patients) versus multiple cytogenetic changes (16 patients). Patients with multiple anomalies had a shorter survival (8 months) than patients with single anomalies (18 months) or those with a normal karyotype (36 months). All these differences were significant. The incidence of multiple anomalies was higher in patients with RAEB and RAEB-t than in those with RA, RARS, and CMMOL (p less than 0.05). However, no chromosome anomaly was specifically associated with any group of FAB classification. Transformation to acute leukemia was observed in 25% of patients with normal karyotype, 41% of patients with single anomalies, and 50% of patients with multiple changes. The incidence of leukemic transformation was significantly higher in patients with multiple anomalies than in those with a normal karyotype (p less than 0.05). Thus, in the present study, FAB classification and chromosome anomalies were of independent prognostic significance. Sequential cytogenetic studies were performed in 23 patients to correlate the cytogenetic and clinical findings during the course of the disease. Six of seven patients with transformation to acute leukemia showed a karyotypic evolution. These findings agree with the view that an unstable karyotype can be associated with a poor prognosis.  相似文献

Two cases of acute myelocytic leukemia (AML) type M4 with trisomy 4 are presented. In one case trisomy 4 was associated with del(3). Both patients had no history of exposure to mutagenic events. In our material the frequency of trisomy 4-AML is not higher than 1%.  相似文献

The objective of this study was to evaluate the feasibility, the toxicity and the efficiency of a BFM-like treatment protocol for acute nonlymphoblastic leukemia (ANLL) of children in which mitoxantrone was substituted for conventional anthracycline. The chemotherapy called for induction (mitoxantrone, cytosine arabinoside, etoposide), consolidation (mitoxantrone, cytosine arabinoside, 6 thioguanine), followed by two intensification courses with cytosine arabinoside plus, respectively, mitoxantrone during the first and etoposide during the second courses. Maintenance therapy consisted of daily 6 thioguanine, four-weekly courses of cytosine arabinoside (s.c. daily during 4 days) and eight-weekly courses of mitoxantrone. The latter drug was pursued up to a total cumulative dose of 150 mg/sqm. Maintenance therapy was stopped at 2 years of diagnosis. Out of 108 patients, 84 (77%) achieved a complete remission, 10 died during induction of hemorrhage, sepsis or pulmonary infiltration by leukemic cells. A total of 32 relapses occurred. The median follow-up was 3.5 years. Actuarial event-free survival, disease-free survival and overall survival at 3 years as 41%, 52%, 56%;, respectively. These results compare favorably with most reported data, and cytogenetic findings appear to be the most important prognostic factor. © 1996 Wiley-Liss, Inc.  相似文献
