This article describes the treatment of an adolescent girl who was congenitally missing all 4 second premolars and had a retained mandibular second primary molar. Various treatment alternatives are discussed, and the final treatment plan of space opening for 3 implants and space closure of the maxillary left second premolar site is presented. 相似文献

Primary salivary gland carcinoma with neuroendocrine differentiation is of rare occurrence, especially so in the parotid gland.
Amongst the various reported primary tumors with neuroendocrine differentiation, acinic cell carcinoma (ACC) one such tumor.
A 48 year old lady presented with a gradually increasing right infra-auricular swelling for a period of 1 year which enlarged
suddenly in a short period. Contrast Enhanced Computed Tomography (CECT) suggested diagnosis of Pleomorphic Adenoma. Fine
Needle Aspiration Cytology (FANC) yielded a cystic fluid suggesting a possibility of Warthin’s tumor or Oncocytic lesion.
Intraoperative findings were suggestive of a Warthin’s tumor. Initial histopathological examination of the tumor was suggestive
of neuroendocrine carcinoma. However, extensive sectioning revealed peripheral islands of ACC. Immunoexpression of S-100,
Neuron specific Enolase (NSE), Chromogranin A and Synaptophysin confirmed the diagnosis. The possibility of neuroendocrine
differentiation in a primary salivary gland tumor should be kept in mind whenever a salivary gland tumor shows only neuroendocrine
histology. 相似文献

The process of wound healing involves a complex interaction between numerous cell types, extracellular matrix molecules, and soluble mediators including growth factors and cytokines. This complex milieu is under active investigation for the purposes of beginning to understand how this environment regulates tissue repair. Quantitation of growth factors, cytokines, and matrix metalloproteinases within surgical wound fluids may help to elucidate this regulatory network, not only in noncomplicated wound healing but also in pathologic lesions such as chronic ulcers. 相似文献

Changing perspectives in 95 children with poststreptococcal acute glomerulonephritis (PSAGN) in our hospital between 1979 and 1988 are reported. Between 1961 and 1970 an average of 31±6.3 patients/year with PSAGN were treated and 70% had antecedent pyoderma. In the present study antecedent pharyngitis was observed in 59 children und pyoderma in 36. In comparison to the decade ending in 1970 our data show: (1) a marked decline in the prevalence of PSAGN (P=<0.0005), (2) a predominance of antecedent pharyngeal infection (P=0.044), (3) a decline in urban and an increase in rural patients with PSAGN (P=0.0483); and in the last decade: (1) a predominance of antecedent pharyngeal infection in children over 6 years of age (P=0.0009) and (2) a predominance of antecedent pyoderma in black children (P=0.0004). 相似文献

Variability in the interpretation of micturating cystourethrography by paediatric radiologists for the diagnosis of vesicoureteric
reflux in children was evaluated. All 265 micturating cystourethrograms (MCUs) that were available from 304 consecutive children
aged 0.5 – 61 months – who were investigated after their first urine infection between 1993 and 1995 as part of a prospective
cohort study – were selected for interpretation. Three experienced paediatric radiologists from the same department independently
interpreted the MCUs according to the grading system of the International Reflux Study in Children, from grades 0 to V, with
the presence of intrarenal reflux also noted. Apart from being informed that urine infection was the indication for the MCU,
no other clinical information was given to the radiologists. The indices of variability used were the percentage of agreement
and the kappa statistic, expressed as a percentage. Both measures were weighted with integers representing the number of categories
from perfect agreement. Disagreement was analysed for children and kidneys. For the diagnosis of vesicoureteric reflux in
individual patients, including grade, the percentage of agreement was 96% – 97% (kappa 90% – 91%) and the weighted percentage
of agreement was 96% – 98% (weighted kappa 93% – 94%). The same high level of agreement was present for individual kidneys,
with a percentage of agreement of 97% – 98% (kappa 89% – 92%) and a weighted percentage of agreement of 98% – 99% (kappa 94% – 95%).
There was near perfect agreement in the interpretation of radiological micturating cystourethrography among three experienced
paediatric radiologists for the diagnosis and grade of vesicoureteric reflux. Any variations in the medical care of children
suspected of having vesicoureteric reflux are not explained by differences in the reporting of this diagnostic test.
