    ABSTRACT: This report describes a case of 21-year-old female with severe maxillary protrusion, and class ІІ/1 dental relationship. The treatment plan was extraction of upper first premolars and retraction of the anterior teeth. Mini-implants were used to provide maximum anchorage to maintain the extraction space. To shorten the retraction time selective alveolar corticotomy was combined with orthodontic therapy. The treatment time was reduced without any adverse effects on the periodontium and the vitality of the teeth.

    ABSTRACT: The burden of chronic respiratory disease (CRD) is alarming. International studies suggest that women with CRD are undersurveyed and underdiagnosed by physicians worldwide. It is unclear what the prevalence of CRD is in the general population of Syria, particularly among women, since there has never been a survey on CRD in this nation. The purpose of this study was to investigate the impact of different patterns of smoking on CRD in women. We extracted data on smoking patterns and outcome in women from the Global Alliance Against Chronic Respiratory Diseases survey. Using spirometric measurements before and after the use of inhaled bronchodilators, we tracked the frequency of CRD in females active and passive narghile or cigarette smokers presenting to primary care. We administered the questionnaire to 788 randomly selected females seen during 1 week in the fiscal year 2009-2010 in 22 primary care centers in six different regions of Syria. Inclusion criteria were age >6 years, presenting for any medical complaint. In this cross-sectional study, three groups of female subjects were evaluated: active smokers of cigarettes, active smokers of narghiles, and passive smokers of either cigarettes or narghiles. These three groups were compared to a control group of female subjects not exposed to active or passive smoking. Exposure to active cigarette smoke but not narghile smoke was associated with doctor-diagnosed chronic obstructive pulmonary disease (COPD). However, neither cigarette nor narghile active smoking was associated with increased incidence of spirometrically diagnosed COPD. Paradoxically, exposure to passive smoking of either cigarettes or narghiles resulted in association with airway obstruction, defined as forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) < 70% according to the Global initiative for chronic Obstructive Lung Disease criteria; association with FEV1 < 80% predicted, evidencing moderate to severe GOLD spirometric grade, and doctor-diagnosed COPD. Physicians tend to underdiagnose COPD in women who present to primary care clinics. Whereas around 15% of enrolled women had evidence of COPD with FEV1/FVC < 70% after bronchodilators, only 4.8% were physician-diagnosed. Asthma did not appear to be a significant spirometric finding in these female subjects, although around 11% had physician-diagnosed asthma. One limitation is FEV1/FVC < 70% could have also resulted from uncontrolled asthma. The same limitation has been reported by the Proyecto Latinoamericano de Investigacion en Obstruccion Pulmonar (PLATINO) study. Contrary to popular belief in developing countries, women exposed to tobacco smoke, whether active or passive, and whether by cigarettes or narghiles, like men are at increased risk for the development of COPD, although cultural habits and taboos may decrease the risk of active smoking in some women. These findings will be considered for country and region strategy for noncommunicable diseases, to overcome underdiagnosis of CRD in women, fight widespread female cigarette and narghile smoking, and promote behavioral research in this field.

    ABSTRACT: BACKGROUND:: BRAF mutations have been implicated in initiating promutagenic cellular melanocytic proliferation mostly based on homogeneous Western-based cohorts. Data addressing the possible interaction between exposure to different solar ultraviolet radiation (UVR) magnitudes and BRAF mutation rate (BMR) in melanocytic nevi are limited. DESIGN:: Extended BRAF testing for 9 mutations in 225 melanocytic nevus (MN) cases derived from 211 patients from 4 different UVR regions: Lebanon (n = 95; 110 kJ·m·yr), Syria (n = 23; 93.5 kJ·m·yr), Kingdom of Saudi Arabia (n = 70; 139 kJ·m·yr), and Pakistan (n = 37; 118 kJ·m·yr) was performed. Data collected included age, gender, anatomic location, and lesion size. Histological parameters recorded were MN type (junctional, compound, intradermal, classical blue, cellular blue, compound and intradermal spitz, and congenital) solar elastosis grade, and nevus pigmentation degree. Cumulative 21-year erythemally effective UV averages were derived from The National Center for Atmospheric Research. RESULTS:: BRAF mutation status was obtained in 210 cases (6.7% failed polymerase chain reaction). Overall, BMR was 62.4% (131/210) with V600E mutation accounting for 98.5% of cases. Discordant mutation status was found in 2 of 10 patients with multiple nevi. BMR differed significantly, yet nonsystematically, among UVR regions; the highest was detected in nevi coming from Syria (18/23 cases, 78%), followed by Pakistan (21/30 cases, 70%), Kingdom of Saudi Arabia (47/70 cases, 67%), and Lebanon (45/87cases, 52%). Mutation rates varied significantly across MN type (P < 0.001); the highest rate was recorded in the intradermal nevus type (33/39 cases, 84.6%), followed by the compound (26/32 cases, 81.2%) and congenital (60/74 cases 81.0%) nevi. Stratified by anatomic location, nevi occurring on the face (61/82, 74%) and trunk (58/78, 74%) had more frequent BMRs compared with those occurring on the upper (7/26, 27%) and lower extremities (5/24, 21%, P < 0.001). Severe pigmentation was less frequent in BRAF mutation-positive nevi [5/131 (4%) vs. 34/79 (43%); P < 0.001]. Multivariate independent predictors of BRAF mutation in MN were age [odds ratio (95% confidence interval ) = 1.43 (1.13-1.74) per 10 years; P = 0.004], anatomic location [P = 0.043 overall], and nevus type [P < 0.001 overall]. UVR region was not an independent predictor of BRAF mutation. CONCLUSIONS:: Increased BRAF mutation with age along with the lack of a UVR magnitude-BRAF mutation association suggests that duration of exposure rather than UVR exposure dose is the more likely link to acquiring the mutation.
