Tooth development is a highly heritable process which relates to other growth and developmental processes, and which interacts with the development of the entire craniofacial complex. Abnormalities of tooth development are common, with tooth agenesis being the most common developmental anomaly in humans. We performed a genome-wide association study of time to first tooth eruption and number of ...
This case series describes the different potential approaches to late-developing supernumerary premolars (LDSP). LDSP are supernumerary teeth (ST) formed after the eruption of the permanent dentition; usually they develop in the premolar region of the upper and lower jaw. The choice to extract or to monitor the LDSP depends on many factors and has to be carefully planned due to the several risk...
Two patients are described with Charcot-Marie-Tooth disease and chronic peripheral neuropathy. Both had dyspnoea, orthopnoea, and evidence of severe diaphragm weakness. Expiratory muscle function was well preserved and abnormalities of gas exchange during sleep were only minor.
Acid-base disorders are common clinical problems resulting from a wide variety of pathophysiological conditions, including newly recognised acquired and genetic causes. The history and physical examination and measurement of blood and urinary indices allow identification of the underlying cause of these disorders in most cases. Treatment directed at correction of electrolyte abnormalities and t...
Dental agenesis is one of the most common congenital craniofacial abnormalities. Dental agenesis can be classified, relative to the number of missing teeth (excluding third molars), as hypodontia (1 to 5 missing teeth), oligodontia (6 or more missing teeth), or anodontia (lack of all teeth). Tooth agenesis may occur either in association with genetic syndromes, based on the presence of other in...
AIM OF THE STUDY Chemotherapeutic treatment in children and adolescents carries a risk of congenital tooth disorders and dentinoma. Study objective is to assess the correlation between tooth abnormalities, early complications of multidrug chemotherapy, and chemotherapeutics used in different antineoplastic therapies in children and adolescents. MATERIAL AND METHODS Enamel defects (development...
Sixteen blind babies who were considered to be showing the characteristics of delayed visual maturation were studied prospectively. The diagnosis was made on clinical grounds, and the criteria for this are discussed. All of these infants developed visual responses between 4 and 6 months of age and had normal or near normal visual acuities by 1 year of age. Long term follow up, however, has show...
BACKGROUND Trends in rhinoplasty techniques have seen a significant shift from closed to open over the last decade.1,2 The ideal surgical approach for rhinoplasty continues to be debated amongst aesthetic surgeons. Each technique has its merits. Open rhinoplasty is deemed the procedure of choice in all but the simplest rhinoplasties, reserving the traditional closed approach for hump reduction ...
Environmental Health Perspectives • volume 120 | number 3 | March 2012 A 103 that include validated threshold values that can be used to identify children at risk for delayed develop ment or clinically significant behavioral problems (Bayley 1993; Gioia et al. 2003; Wechsler 2002). The comparison of the case child to these values is valid because the distribution of scores for children in our s...
Teeth are rarely submitted to general pathology departments, but on the rare occasions they are, the response is often confusion. This practically focused review aims to demystify the assessment of teeth, outlining the abnormalities which may be assessed without specialist equipment and others which may require specialist input. We will also provide a brief summary of some of the more common de...
