Background The Tzanck smear is a simple, easily applicable, rapid, and inexpensive test for the diagnosis of erosive vesiculobullous, tumoral, and granulomatous diseases. The diagnostic accuracy of the Tzanck smear is known, but its diagnostic reliability has been evaluated only in herpetic infections and basal cell carcinoma. Objectives The aim of this study was to evaluate the diagnostic reliability of the Tzanck smear in erosive vesiculobullous, tumoral, and granulomatous diseases. Methods Patients evaluated by Tzanck smear at Ba?kent University Faculty of Medicine, Department of Dermatology, between February 2009 and July 2010, were included. Three dermatologists were involved in the study. Dermatologist A performed a clinical dermatologic examination, took the smear material, made a clinical diagnosis, and compared the clinical and cytological diagnoses. Dermatologists B and C evaluated the smears. Agreement between the latter two dermatologists on the cytological diagnoses was determined. Results In 500 patients, a total of 272 (54%) erosive vesiculobullous, 190 (38%) tumoral, and 38 (8%) granulomatous lesions were diagnosed. The diagnostic reliability of the Tzanck smear was reasonably substantial (κ = 0.59) for all types of lesions, substantial for erosive vesiculobullous (κ = 0.79) and granulomatous (κ = 0.68) lesions, and moderate (κ = 0.50) for tumoral lesions. Conclusions The Tzanck smear may be used for the evaluation of erosive vesiculobullous and granulomatous lesions with brief training. However, the evaluation of tumoral lesions by Tzanck smear requires more experience. 相似文献

Nocturnal enuresis is a common problem and occurs in 15 to 20 percent of 5-year-old children. The etiology of nocturnal enuresis remains unknown and is probably multifactorial. In this study 52 children aged between 6-17 years with tuberculosis were questioned for nocturia and nocturnal enuresis, retrospectively. Nocturnal, enuresis was found in 12 (23%) and nocturia in 22 (42%) of the children, respectively. After specific treatment with antituberculosis drugs nocturnal enuresis and nocturia were improved in 5 and 21 children, respectively. However, it could not be explained why these disorders were much higher in children with tuberculosis than healthy children. The findings suggest that nocturnal enuresis and nocturia may be in a high frequency in children with tuberculosis; however, the authors think that prospective and more extensive studies should be performed to clarify these preliminary findings. 相似文献

The purpose of this retrospective study was to evaluate infectious complications in patients receiving mobilization chemotherapy for stem cell collection prior to autologous peripheral blood stem cell transplantation. An additional goal was to evaluate risk factors associated with the development of infectious complications. At the Medical College of Georgia BMT center, 54 patients were administered mobilization chemotherapy for the purpose of collecting stem cells between June, 1997, and May, 2002. All patients received Filgrastim in addition to chemotherapy, and 50 of 54 patients received prophylactic acyclovir, fluconazole, and ciprofloxacin until neutrophil recovery. The median duration to neutrophil recovery was 11 days. Fourteen of 54 (26%) patients developed fever/infections during the mobilization phase. One patient developed both a catheter-related infection and Clostridium difficile colitis, increasing the total number of infectious episodes to 15. Twelve patients had a documented site of infection whereas 2 patients had neutropenic fever with no identifiable source. Eight of the 15 (55%) infections were Gram-positive catheter infections. All the patients were treated successfully with antibiotics. No systemic fungal infections were identified and none of the patients died from complications related to mobilization chemotherapy. Logistic regression was applied for univariate and multivariate analysis and showed that age, sex, diagnosis, neutrophil recovery, disease status, use of salvage chemotherapy, and mobilization regimen used did not affect the infection rate. In our series of 54 patients, 14 patients developed fever/infections during mobilization. Although there is a substantial risk of infectious complications among patients who receive mobilization chemotherapy, it is not clear that prophylactic antibiotics decrease infectious complications. Because the vast majority of infections are Gram-positive catheter infections, it appears reasonable to employ Gram-positive prophylaxis. Controlled studies should be conducted to define the optimum mobilization regimens as well as the optimum combination of prophylactic antibiotics. 相似文献

OBJECTIVES: To investigate the expression and clinical significance of MMP-2, MMP-7, MMP-9, and TIMP-1 in patients with nasal polyposis (NP) and chronic rhinosinusitis (CRS). STUDY DESIGN: Prospective study. SUBJECTS AND METHODS: This study involved 54 patients. There were three groups: nasal polyposis group, chronic rhinosinusitis group, and control group. Specimens were collected during endoscopic sinus surgery. Each sample was immunohistochemically examined. RESULTS: Expression of MMP-2 was found significantly increased in NP, whereas MMP-7 expression was found significantly increased in CRS (P < 0.001). TIMP-1 was significantly high in control group compared to CRS and NP (P < 0.001 and P = 0.002, respectively). CONCLUSIONS: Different regulation type of activation of MMPs has been found in these two diseases. If MMP-2 expression is intense in the mucosa, then this ends with polyp formation; if MMP-7 expression is intense, it ends with CRS or stays as CRS. 相似文献

rhG-CSF is increasingly used for stimulation of granulopoiesis and stem cell mobilization in healthy donors for allogeneic stem cell transplantation. However, a possible association between thrombosis and rhG-CSF administration has been reported. For that reason, in this study, we investigated the effect of rhG-CSF on platelet aggregation in whole blood of 10 healthy volunteers. Three concentrations of rhG-CSF solution (1, 10 and 100 ng/ml) were prepared. Each concentration of rhG-CSF solution and a control diluent without rhG-CSF were incubated with whole blood. Incubation with rhG-CSF solutions would result in 0.1, 1.0 and 10 ng/ml rhG-CSF concentrations in the blood. After incubation, aggregation responses were evaluated with ADP (5 and 10 microM) and collagen (2 and 5 microg/ml) in whole blood. When compared to control, preincubation with all dilutions of rhG-CSF augmented aggregation of platelets induced by ADP and collagen in a statistically significant manner (p < 0.05 for all comparisons). There was also a relationship between rhG-CSF concentration (1, 10 and 100 ng/ml) and augmentation of platelet aggregation response (p < 0.0001 for 5-10 microM ADP; p < 0.0001 for 2-5 microg/ml collagen). In conclusion, this study with an in vitro model showed that rhG-CSF administration may lead to platelet hyperaggregability. 相似文献

Endobronchial metastases: a clinicopathological analysis 总被引:1,自引:0,他引:1
OBJECTIVE: It is important to distinguish endobronchial metastases (EBM) from both primary lung cancers and benign lesions, as treatment will differ. The clinicopathological characteristics of EBM cases were documented to see whether any distinguishing features exist. METHODOLOGY: Histological cases diagnosed as EBM in the pathology laboratory of a tertiary hospital were re-evaluated. Symptoms, primary tumour sites, recurrence interval, radiological and bronchoscopic features, and histopathological properties were assessed. RESULTS: There were 18 cases (eight female, 10 male) with EBM. All were diagnosed by bronchoscopic bronchial biopsy. The primary tumour sites were: colorectal (4), breast (3), renal (3), lymphoma (3), rhabdomyosarcoma (2), bladder (1), thyroid (1) and malignant melanoma (1). The mean time from the diagnosis of the primary tumour to their presentation was 3.89+/-1.09 (range, 0--19) years. In five patients, EBM was diagnosed synchronously with their extra pulmonary primary tumour. Two had other metastatic sites. Haemoptysis and cough were the more common symptoms. Interestingly, three patients were asymptomatic. There was no predilection for a particular airway segment to be involved but a predilection for the upper lobe existed. Endoscopic appearance was polypoid in 10 cases and mucosal infiltration in the remainder. Histopathological examination revealed epithelial tissue at the surface of the tumour in nine cases and four of these were metaplastic. In all but one there was inflammation, mainly lymphocytic. Necrosis was present in 10 cases and bleeding was seen in four. There were no statistically significant differences between the level of lymphocytic inflammation and other clinicopathological parameters. CONCLUSION: EBM is a rare condition that can be synchronous or occur late. Surprisingly, it can be asymptomatic. It is usually found in the upper lobes. Lymphocytic inflammation is a common histopathological finding. There is need for further studies to clarify the clinical importance of EBM. 相似文献
