Epidermodysplasia verruciformis (EV) manifests early in childhood as pityriasis versicolor (PV)–like macules on sun-exposed sites such as the face. These hypopigmented lesions closely resemble commoner pediatric dermatoses such as PV or pityriasis alba. In this report of two cases, we describe the distinguishing dermoscopic features of PV-like macules in EV. Unfocused dotted vessels in a hypopigmented or erythematous background with whitish scales and pigment diluted vellus hairs on dermoscopy should raise the suspicion of EV in children presenting with PV-like lesions. 相似文献

Equine piroplasmosis is a tickborne disease of equids with worldwide distribution, caused by Theileria equi and Babesia caballi. The aim of this study was molecular detection of T. equi and B. caballi in donkeys in northeastern Iran and investigate the association between positivity of piroplasm infection and host-related factors. In the present study, Blood samples were collected from 106 apparently healthy donkeys (Equus asinus) in North Khorasan province, Iran. Blood smears were prepared and stained by giemsa method. DNA was extracted from blood and then multiplex-PCR was done for detection of any piroplasms infection. According to the results, four donkeys showed T. equi in blood smears but B. caballi was not found. Also, fifty four donkeys (50.94%) showed T. equi infection using multiplex-PCR. No siginificant difference was observed between the frequency of T. equi infection with host-related factors in donkeys. This is the first report on the molecular detection of eqiune piroplamosis in donkeys in Iran. Also, no significant association was found between the rate of T. equi infected animals.Key Words: Babesia caballi, Donkey, PCR, Theileria equi 相似文献

This study compared the push‐out bond strength of mineral trioxide aggregate (MTA) and a new endodontic cement (NEC) as root‐end filling materials in root‐end cavities prepared by ultrasonic technique (US) or Er,Cr:YSGG laser (L). Eighty single‐rooted extracted human teeth were endodontically treated, apicectomised and randomly divided into four following groups (n = 20): US/MTA, US/NEC, L/MTA and L/NEC. In US/MTA and US/NEC groups, root‐end cavities were prepared with ultrasonic retrotip and filled with MTA and NEC, respectively. In L/MTA and L/NEC groups, root‐end cavities were prepared using Er,Cr:YSGG laser and filled with MTA and NEC, respectively. Each root was cut apically to create a 2 mm‐thick root slice for measurement of bond strength using a universal testing machine. Then, all slices were examined to determine the mode of bond failure. Data were analysed using two‐way anova . Root‐end filling materials showed significantly higher bond strength in root‐end cavities prepared using ultrasonic technique (US/MTA and US/NEC) (P < 0.001). The bond strengths of MTA and NEC did not differ significantly. The failure modes were mainly adhesive for MTA, but cohesive for NEC. In conclusion, bond strengths of MTA and NEC to root‐end cavities were comparable and higher in ultrasonically prepared cavities. 相似文献

We report a case of an elderly man presenting with co-existing diffuse idiopathic skeletal hyperostosis (DISH) and ossified posterior longitudinal ligament (OPLL) resulting in central cord syndrome. Only three such cases have been reported co-existing with DISH. The patient recovered most of his neurological deficit through conservative management. A discussion on the radiological features of DISH co-existing with OPLL and how these differ from ankylosing spondylitis (AS) follows. 相似文献

Spectroscopy is close to becoming an integral part of the clinical MR examination to achieve a complete morphological, functional, and metabolic evaluation of the human heart. 31P-NMR spectroscopy is used to noninvasively assess human myocardial energy metabolism. Abnormalities in the phosphocreatine (PCr) to ATP ratio are observed in ischemic heart disease, heart failure, transplanted hearts, and hypertrophic cardiomyopathy. NMR spectroscopy 31P spectra obtained at rest, during exercise or pharmacological stress allow the observation of the earliest metabolic responses of myocardial ischemia. 1 spectroscopy can evaluate the concentration of intracellular creatine and myocardial lipids as a means of evaluating myocardial viability. The increase in total 23Na in ischemic tissue provides information about the extent and location of viable tissue. Higher magnetic fields, gradient strength, and technological advances in pulse sequence and localization will result in better spatial and temporal resolution improving the clinical utility of the technique. 相似文献

At least one in a hundred consultations in general practice in Australia involves women being treated for breast cancer. The challenges presented during these consultations test the quality of primary care. Firstly, women are reported to prefer to discuss their breast cancer-related problems with a specialist even though research suggests that patients generally prefer to consult with a general practitioner (GP). The extent to which these patients will have maintained or return to their previous level of functioning will be a reflection on the quality of primary care, as some breast cancer-related health issues may persist beyond the time period when they are undergoing specialist review. Further, psychosocial matters, sexuality and relationships may require repeated review and perhaps consultations involving family members and would therefore be better addressed by a GP. An increasingly urgent need exists to review how best to support people who are successfully treated for life limiting illnesses, such as breast cancer. 相似文献
