Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare recessive disorder resulting from mutations in the autoimmune regulator ( AIRE ) gene. There is no information on AIRE mutations in Indians. In a cross-sectional study, nine patients (eight families), from four referral hospitals in India, were studied for AIRE mutations by direct sequencing. We screened for new mutations in 150 controls by allele-specific PCR. The patients had 1–7 known components of APECED. Three patients had unusual manifestations: presentation with type 1 diabetes; chronic sinusitis and otitis media; and facial dysmorphism. All patients carried homozygous, probably recessive, AIRE mutations. Two unrelated patients from a small in-bred community (Vanika Vaisya) in south India carried an unreported missense mutation, p.V80G, in the N-terminal caspase recruitment domain. Another unique mutation, p.C302X, resulting in a truncated protein with deletion of both zinc-finger domains, was detected in a patient from Gujarat. Neither mutation was detected in controls. Other mutations, previously described in Caucasians, were: 13 base pair deletion (p.C322fsX372) in 4 (38%), and Finn-major (p.R257X) and p.R139X (Sardinian) mutation in one subject each. In conclusion, in this first series of APECED in Indians, we detected AIRE mutations previously reported in Caucasians, as well as unique mutations. Of these, p.V80G is possibly an ancestral mutation in an in-bred community.  相似文献

We present a technique for transpharyngeal imaging of the bilateral carotid arteries completed towards the end of a transesophageal echocardiogram. To our knowledge, this is the first report that demonstrates the bifurcation of the right common carotid artery into the right internal and external carotid arteries with a transesophageal echocardiographic probe.  相似文献

We present two- and three-dimensional transesophageal echocardiographic findings of two adult patients who presented for reoperation after previous repair of a partial atrioventricular (AV) septal defect. Both patients had a cleft in the left AV valve with severe regurgitation. One patient had an additional 10 x 5 mm defect connecting the left ventricle to the right atrium through the AV junction. Three-dimensional echocardiography was superior to two-dimensional echocardiography in comprehensively delineating the anatomical defects in the left AV valve and the AV junction.  相似文献

Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disorder. Renal involvement has the worst prognosis. However, renal cortical necrosis is extremely unusual in SLE. In this case report, we describe the autopsy findings in a young female patient with SLE presenting with renal failure. At autopsy, there was Libmann–Sacks endocarditis with multiorgan infarcts and renal cortical necrosis. Secondary antiphospholipid antibodies contribute to the cardiac and renal manifestations in SLE. We discuss the incidence and pathogenesis of endocarditis with differential diagnosis for cortical necrosis in a patient of SLE.  相似文献

Aim

ZMC fractures are the common facial injuries. The main causes of fractures are trauma due to RTAs, assaults, falls, sports related injuries, and the civilian warfares. This study is to evaluate and review the etiology, incidence, clinical findings and treatment of ZMC fractures. A sincere effort has been put forward in the management of ZMC fractures and their efficacy is evaluated in the larger interest of the patients.

Materials and methods

In this study 101 patients having displaced ZMC fractures with insignificant medical history were reviewed to evaluate the versatility of its management, with the main emphasis on post operative stability, restoration of mouth opening, wound healing, esthetic restoration of the prominence of cheek and the complications encountered.

Results

A total of 101 patients were reviewed for the management of ZMC fractures. All the cases included were managed during the period from August 2007 to August 2009 in the Department of Oral and Maxillofacial Surgery, Mamata Dental College and Hospital, Khammam. The extremes of ages in this study ranged from 17 to 60 years with the mean of 43. RTA was the most common cause of injury. Seventy-eight patients (77 %) were managed with surgical treatment.

Conclusion

Attention should be paid to improvement in automobile safety devices and compliance by motor vehicle occupants in addition to the improvement of the rules and regulations in sporting activities.
