Narrow band imaging (NBI) is an optical filter technology that improves the visibility of capillaries, veins and other subtle tissue structures, by narrowing the bandwidth of spectral transmittance using optical filters. In this short communication, we want to share our preliminary experience in assisted reproductive technology patients where we had used NBI hysteroscopy for the evaluation of uterine cavity abnormalities who had previous IVF failure. 相似文献

Background
In-stent restenosis (ISR) is the major limitation of percutaneous coronary stenting procedure. The elements like nickel, chromate and molybdenum are known to cause contact allergy. Hypersensitivity reaction, against these metal ions, may be one of the reasons of ISR. Cobalt chromium coronary stents, which are increasingly being used in percutaneous coronary interventions, have more nickel amount than the stainless steel stents.Objective
We aimed to investigate the association between nickel hypersensitivity reaction and ISR in patients treated with cobalt chromium coronary stents.Methods
Epicutaneous patch tests for nickel were applied to 31 patients who had undergone elective cobalt chromium coronary stent implantation and had ISR in control angiogram. Thirty patients, without ISR, were included as the control group. Patch test results and other clinical variables were compared.Results
There was no statistically significant difference of the mean age, sex, body mass index, rate of hypercholesterolemia, diabetes, hypertension and smoking between the patients with and without ISR. All other lesion characteristics were similar in the 2 groups. According to the patch test results, 7 patients had nickel contact allergy. All of these patients were in the ISR group, which was statistically significant (p<0.006).Conclusion
Patients treated with cobalt chromium coronary stents and had ISR were found to have significantly more nickel allergy than the control group. Nickel allergy may play role in restenosis pathophysiology. 相似文献74.

The aim of this study is to evaluate the significance of immunohistochemical expression of Galectin-3 in the differential
diagnosis of benign and malignant thyroid nodules. We studied the fine needle aspiration specimens of 38 patients who had
evaluated for nodular goiter and undergone a thyroid surgery between 2004–2005. Slides had been stained immunocytochemically
with Galectin-3. The cytoplasmic staining of Galectin-3 was analyzed. Three cases of five follicular carcinomas had positive
staining for Galectin-3, while two had not. Two cases with follicular adenomas were negative for Galectin-3. Five cases of
six papillary carcinomas had positive staining for Galectin-3, while one case (the case with a papillary microcarcinoma) had
not. The single cases with medullary and anaplastic carcinomas were negative for Galectin-3. None of the cases with a benign
thyroid pathology had positive staining for Galectin-3. Galectin-3 immunocytochemical staining, had a sensitivity of 61.5%,
specificity of 100%, positive predictive value of 100%, and negative predictive value of 83.3% for thyroid malignancies. For
the evaluation of follicular neoplasm, Galectin-3 immunocytochemical staining had a sensitivity of 60%, specificity of 100%,
positive predictive value of 100%, and negative predictive value of 50%. Galectin-3 expression in thyrocytes is a strong indicator
of a malignant proliferative lesion especially for papillary and to an extent in follicular thyroid neoplasms. Galectin-3
could be used as a supplementary marker for cytological diagnosis. 相似文献

Lupus vulgaris and scrofuloderma are the opposite poles of cutaneous tuberculosis. Lupus vulgaris of a giant size and scrofuloderma in the vicinity of this lesion were both present in a 70-year-old female patient. The purified protein derivative of tuberculin (PPD) skin test was strongly positive. In histopathological examination, granulomatous infiltration without caseation necrosis was seen in the dermis. The patient was treated with a four-drug therapy consisting of pyrazinamide (25 mg/kg), isoniazid (5 mg/kg), rifampin (10 mg/kg) and ethambutol (15 mg/kg) daily for 2 months, followed by dual therapy with isoniazid and rifampin for 6 months. Her cutaneous lesions significantly regressed after 4 months, leaving keloid scars. 相似文献

Evidence of an association between mannose binding lectin codon 54 polymorphism and adenoidectomy and/or tonsillectomy in children 总被引:1,自引:0,他引:1
Koturoglu G Onay H Midilli R Pehlivan S Eren E Itirli G Kurugol Z Apaydin F Ozkinay C Ozkinay F 《International journal of pediatric otorhinolaryngology》2007,71(8):1157-1161
Mannose binding lectin (MBL) is a calcium-dependent lectin that plays an important role innate immunity by activating the complement pathway. There have been a number of studies describing an association between the MBL genotype and disease susceptibility. MBL deficiency has been described as one of the factors leading to a number of infections in children with recurrent upper respiratory tractus infections (URTI). We hypothesized that MBL deficiency may be associated with recurrent URTI, which requires adenoidectomy and/or adenotonsillectomy. In this study to clarify this hypothesis we investigated whether there may be an association between two low producing MBL variants and adenoidectomy and/or tonsillectomy due to recurrent URTI in children. Blood samples were collected, adenoidectomy and/or tonsillectomy due to recurrent URTI and 50 controls (mean age 80.53 +/- 32.62 months). In all patients and controls codon 54 and codon 57 polymorphisms of the MBL gene were analyzed. None of the subjects from the patient group and control group carried codon 57 polymorphism of the MBL gene. The frequency of low-level MBL genotypes (AB and BB) for codon 54 polymorphism in the patient group was found to be significantly higher compared to the control subjects (55.7% versus 14%) (p<0.001). This study shows that the presence of low-level MBL alleles is associated with adenoidectomy and/or tonsillectomy caused by recurrent URTI in children. 相似文献

Macrocephaly describes a head circumference greater than two standard deviations above the mean and is a feature of a number of genetic syndromes. Here we report on two patients with microcephaly, immune deficiency and anemia. In addition, one case had periventricular leukomalacia and the other case had myelinisation delay in periventricular white matter development. These cases may represent a distinct new syndrome. 相似文献
