Analysis of Dental Arch Symmetry of Children With Unilateral Cleft Lip and Palate: Seven-Year Follow-Up.

Background: Orofacial cleft is the most common craniofacial deformity, resulting in facial anatomical disorders.

Aim: To evaluate maxillary dental arch symmetry of children with unilateral complete cleft lip, alveolus, and palate before and after primary surgeries.

Design: A total of 27 dental casts were analyzed: (T1) Presurgical; (T2) Postsurgical 1; and (T3) Postsurgical 2.

Alcohol consumption and preference in female rats induced by reward downshift reveals sex generality of the modulatory role of physical activity.

Increased voluntary consumption of alcohol has been demonstrated in male rats exposed to frustrative reward downshift (the emotional self-medication effect). Access to a wheel for voluntary running abolished this effect in male rats, suggesting an attenuating effect of physical exercise on the negative affect induced by reward downshift and its consequences on drug intake. The present study analyzed this effect in female rats.

Concurrent nodular lymphocytic myositis and myasthenia gravis. A case report.

Localized painful nodules associated with focal myositis have been previously documented, either as isolated occurrences or in conjunction with systemic illnesses, such as polymyositis [1-4]. These nodules typically manifest over the course of 2-8 weeks and exhibit histological features consistent with inflammatory myositis. Here we present a unique case of a patient with a history of myasthenia gravis, who experienced exacerbation of myasthenic symptoms, accompanied by the development of palpable, tender nodules on her thighs and proximal weakness.

Across-surface distances after one- and two-stage palatoplasty in children with oral cleft.

The goal of this study was to digitally evaluate the development of maxillary dental arches of children with unilateral cleft lip and palate treated with one- and two-stage palatal closure. One hundred and sixty-eight digitized dental models of cheiloplasty and one-stage palatoplasty (G1) and cheiloplasty and two-stage palatoplasty (G2) were evaluated at preoperative time 1 (T1), preoperative time 2 (T2), and postoperative (T3). The following surface distances were evaluated: across surface distance; cleft widths anterior (P-P') and posterior (U-U') cleft widths, intercanine width (C-C'), and intertuberosity width (T-T'); smallest (P'-T') and largest (P-T) segment lengths; and smallest (C'-D') and largest (C-D) segment cleft depths.

Fluctuating arch symmetry: a comparison of two methods of assessment - applicability and efficiency.

Introduction: Symmetry is balance, some correspondence in the size, form, and arrangements of parts on opposite sides of a plane, line, or point. The opposite of this concept is asymmetry, or imbalance.

Objective: This retrospective study compared two methods for assessing arch symmetry with linear measurements based on triangles, to determine their applicability and efficiency.
