OBJECTIVE   The purpose of this project was to develop objective computer-based methods to measure nasal asymmetry and abnormality in children undergoing treatment of unilateral cleft lip (UCL) and to determine the correlation of these measures to clinical expectations. PARTICIPANTS   Thirty infants with UCL undergoing cleft lip repair; 27 children with UCL aged 8 to 10 years who had previous...

A population-based case-control study was carried out in Norway between 1996 and 2001. The aim was to evaluate the association between maternal intake of vitamin A from diet and supplements and risk of having a baby with an orofacial cleft. Data on maternal dietary intake were available from 535 cases (188 with cleft palate only and 347 with cleft lip with or without cleft palate) and 693 contr...

Colonization of new habitats through dispersal of phytoplankton cysts might be limited, if resident populations outcompete invaders during germination. We reciprocally transferred Gonyostomum semen (Raphidophyceae) cysts from three lakes into native and foreign waters originating from the respective habitats. Germination rate and germling growth were impacted by water origin, but there was no p...

Cysts of the vallecula are rare, accounting for 10.5% to 20.1% of all laryngeal cysts. Vallecular cysts may present with diverse symptoms affecting the voice, airway, and swallowing. We describe the evaluation and treatment of a 70-year-old woman who presented with dysphagia caused by large bilateral vallecular cysts.

Larval rainbow trout (Oncorhynchus mykiss) were reared from hatch under control ([Na(+)]=0.60 mmol l(-1)) or high NaCl ([Na(+)]=60 mmol l(-1)) conditions to elucidate the driving force for the ontogeny of branchial Na(+)/NH4 (+) exchange, one of the earliest gill functions. We hypothesized that if Na(+) uptake is the driving force, then in high NaCl there would be a delay in the skin-to-gill sh...

REPEATED reports from Japan and from north European countries have brought attention to a new clinical syndrome called "pulseless, or Takayasu disease." The condition is found in young women and is characterized by thrombosis of the vessels deriving from the arch of the aorta associated with cerebral, ocular, and upper extremity symptoms. Its etiology is obscure. We are presenting a case of thi...

We measured unidirectional ion fluxes of fish collected directly from the Rio Negro, an extremely dilute, acidic blackwater tributary of the Amazon. Kinetic analysis of Na(+) uptake revealed that most species had fairly similar J(max) values, ranging from 1,150 to 1,750 nmol g(-1) h(-1), while K(m) values varied to a greater extent. Three species had K(m) values <33 micromol L(-1), while the re...

The sellar xanthogranuloma is a rare lesion of the sellar-parasellar region difficult to differentiate from other tumors such as craniopharyngiomas or Rathke's cleft cyst in the preoperative evaluation. As they are recently recognized as a separate entity and the few number of reports in the literature, its etiology is unknown and its impact remains uncertain. This article will describe the fir...

A rare case of symptomatic Rathke's cleft cyst in a 26-year-old female is reported. The clinical and radiological features of this lesion are described with emphasis on the differential diagnosis between Rathke's cleft cyst and craniopharyngIOma. Rathke's cleft cysts present a common incidental intrasellar autopsy finding occurring in 13% to 22% of randomly examined pituitary glands [1]. These ...

Congenital midline cervical cleft is a rare anomaly of the anterior neck. The diagnosis is typically made on the basis of the lesion's characteristic clinical presentation at birth. It appears to occur as a result of a failure of fusion of the paired second branchial arches in the midline during embryogenesis. Surgical intervention is necessary to avoid potential long-term complications, such a...
