Objective. To determine the morphological features in the anterior mandibular region, the presence of lingual foramen and canal dimensions in Saudi subjects that would interfere with standard implant placement. Methods. CBCT scans of patients seeking implant treatment were examined. Based on the dentition status, patients were categorized into edentulous (group I) and dentulous (group I). On the panoramic view, the distance between the two mental foramina was divided into vertical segments of 10 mm width. In each segment, vertical bone height and buccolingual thickness at three levels (alveolar crest, 5 mm, and 10 mm apical to the crest) were assessed. The lingual foramen prevalence and canal features were assessed as well. Comparisons between the two groups regarding the assessed parameters were performed using the t-test. The percentage of edentulous mandibles with thickness <6 mm corresponding to the standard implant diameter was also calculated. Results. Following the inclusion and exclusion criteria, group I consisted of 45 subjects and group II comprised 26 subjects. Bone height and thickness at the crestal level were significantly less in edentulous (I) than dentate mandibles (II) ( P < 0.0001 ). The lingual foramen was detected in 90% of patients. In both groups, males had significantly greater mandibular height than females ( P = 0.02 and 0.005). At the crestal level, the thickness was <6 mm in 50% of the anterior mandibular segments. Conclusion. Half of the edentulous patients may receive normal size implants in the anterior interforaminal segments, while the other half will be limited to narrow implants (3.5 mm and less). The lingual foramen location, canal size, and position may represent another limitation for implant placement in that segment.

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices and maxillary sinus floor triggered a significant reduction of maxillary sinus mucous membrane thickening. The presence of periodontal bone loss significantly increases maxillary sinus mucous membrane thickening.

Aim and Objective: To assess the level of awareness among local adult population (orthodontically untreated) regarding orthodontic treatment and procedures. Materials and Methods: A cross-sectional study was planned by accessing 100 subjects comprising of 2 groups (50 male and 50 female). After due ethical clearance, a self-structured questionnaire consisting of 17 questions was given to a group of randomly selected 100 individuals with an age range of 20 to 30 years. Results: The overall awareness of orthodontics as a speciality among both the groups was only 52% to 56%. Statistically insignificant difference was found in the knowledge and awareness of orthodontic treatment among both male and female subjects, that is, Group I and II. Also, those who knew about the orthodontic treatment did not opt for it because of high cost and longer duration involved. Conclusion: More than half of the population is unaware of the scope of orthodontic treatment, and thus, they do not seek any assistance. Hence, more efforts are needed to create awareness about orthodontics and the associated benefits.

Abstract Background Fabry disease is a rare X-linked storage disorder caused by a deficiency of the lysosomal enzyme α-galactosidase A and generally causes multi-organ dysfunction. Heart disease is the main cause of death, due to severe left ventricular (LV) systolic dysfunction and sudden death. In several heart diseases, the LV systolic dysfunction and ventricular arrhythmias are associated with mechanical dispersion (MD). The presence of MD in patients with FD has not been studied yet. In this cross-sectional study, we investigated the prevalence of MD in patients with FD. Methods Complete echocardiographic and speckle tracking echocardiographic (STE) data were collected. MD is an index of inter-segmental discoordination of contraction which has been used to quantify LV dyssynchrony and was defined as the standard deviation (SD) of time to peak negative strain in 17 left ventricular segments. Patients were divided into two groups according to whether or not they had left ventricular hypertrophy (LVH). MD was defined as an SD >49 msec. Results We studied 108 patients with FD, 24 patients (22%) were excluded due to inadequate imaging quality or presence of comorbidities, so the final study population consisted of 84 patients (mean age 33.3±14.6 years, 60.7% women). LVH in FD appears at older ages than in patients without LVH (48±12.5 y/o vs 27.8±11.1 y/o, p<0.0001). Patients with FD without LVH (Group I) showed normal global longitudinal peak strain (GLPS) (21.2±2.5%) and no MD (32.7±8.8 msec). In Group II (n=23) patients with FD with LVH, 17 (73.9%) had MD >49 msec prolonged mechanical dispersion (73.3±20.7 msec) and reduced GLPS (13.6±4.0%). MD was more pronounced in Fabry patients with LVH than in patients without LVH (63.4±24.7 msec vs. 32.7±8.8 msec, p<0.0001). GLPS was lower in Fabry patients with LVH than in patients without LVH (15.3±4.7% vs 21.2±2.5%, p<0.0001). Figure 1 Conclusions To our knowledge, this is the first study to demonstrate the prevalence of mechanical dispersion in patients with FD. Mechanical dispersion was seen in 73.9% of patients with FD with LVH. This dyssynchrony should be taken into account in patients who develop heart failure or life-threatening ventricular tachyarrhythmias.

Objective. The aim of the current study was to laparoscopically investigate the effects of peritoneal nonclosure on the sites, types, and degrees of adhesions developed after primary caesarean section (CS) in women complaining of secondary infertility after first CS delivery. Study Design. This was a cross-sectional study, where 250 women suffering from secondary infertility after their first CS had been recruited. They had been classified into group I (n = 89), where both the visceral and parietal peritoneum had been left opened; group II (n = 75), where only the parietal peritoneum had been closed; and group III (n = 86), where both peritoneal layers had been closed. Laparoscopy had been used to classify those adhesions according to the location, severity, and their adverse impact on the reproductive capacity. Results. Both adnexal and nonadnexal adhesions had been found significantly higher in group I, while adnexal types of adhesions were significantly higher after nonclosure of the visceral peritoneum in group II. Laparoscopic tubal surgery performed included tubo-ovariolysis, fimbrioplasty, and neosalpingostomy. Pregnancy rate was found correlating with the adnexal adhesion location and score. Conclusion. Nonclosure of the peritoneum in CS is associated with more adhesion formation, which might adversely affect the future women reproduction.

A cross sectional study carried out with patients having suspected paranasal sinus (PNS) mass during January 2009 to October 2010 to evaluate the fungal diseases in PNS by computed tomographic(CT) image and comparison of the findings of this modality with histopathological result. Among the total 76 patients, the mean age of the patients was 35.95 ± 18.24 and common complaints of the patients were nasal obstruction (73.7%) and maximum 53.9% patients had PNS mass in maxillary sinuses. Out of all cases 10 were diagnosed as having fungal infection/mass by CT scan and confirmed by histopathological evaluation. Two cases were diagnosed as having fungal infection/mass by CT scan but not confirmed by histopathological findings. Of 64 cases of other than fungal infection/mass, which were diagnosed by CT scan, six were confirmed as having fungal infection/mass and 58 were other than having fungal infection/mass by histopathology. Sensitivity of CT scan to diagnose fungal infection/mass was 62.5%, specificity 96.7%, positive predictive value 83.3%, negative predictive value 90.6% and accuracy 89.5%. CT scan of the fungal diseases in paranasal sinus provides more information and better image quality and CT diagnosis correlate well with the findings of histopathology.

The study was conducted in department of physiology, B J Medical College, Ahmedabad from Mar. 2012 to Feb. 2013. This was a cross-sectional study to evaluate the effect of smoking on lung   function and serum lipids in asymptomatic smokers   and comparable non   smokers. The mean of the various spirometric parameters were calculated of the subjects for both the groups. The mean FVC in group I and group II was 2.60 ± 0.62 L and 4.10 ± 0.64L respectively. The mean FEV1 in group I was 1.91 ± 0.57L and     3.19 ± 0.77L in group II Group I had mean FEF25% - 75% and PEFR of 1.98 ± 0.67L/sec and 4.50 ± 1.57L/sec respectively. Group II had mean FEF25 – 75% of 4.22 ± 1.23L/sec and a mean PEFR of 7.22 ± 1.42L/sec. In young smokers and asymptomatic, still the spirometric values were significantly deranged as compared to controls. Even smokers with history of less pack years of smoking also had significant abnormalities of lung function. All he spirometric values in the two groups had statistically highly significant difference and were higher in non-smokers as compared to smokers. The spirometric values were reduced in smokers with history of smoking for as low as two pack years. Keywords: Progression, PFT, Asymptomatic & Smokers

ABSTRACT HAART (Highly active antiretroviral therapy) has transformed a fatal disease to a chronic, manageable disease. But long term toxicities are emerging after prolonged exposure to antiretroviral therapy(ART). Adverse metabolic effects like dyslipidemia, increased blood pressure, and insulin resistance(IR) have been attributed to HAART. Therefore, the use of HAART raises concerns regarding metabolic disorders and cardiovascular risk in HIV(Human immunodeficiency virus) infected patients. Objective: To determine the prevalence of insulin resistance in a cohort of HIV infected patients on HAART as compared to HAART naïve PLHIV(People living with HIV) Methods: A cross sectional study includes 53 subjects, out of which 26 were PLHIV on ART –Group I, 27 were ART naïve PLHIV-Group II was conducted. Insulin resistance was determined by homeostasis model assessment (HOMA-IR) mathematical model. Statistical analysis was performed to assess the association between demographic, clinical characteristics, laboratory results and insulin resistance. Results: 69.5 % PLHIV on HAART showed IR, as compared to 37 % of ART naïve PLHIV (p= 0.01). MetS(Metabolic Syndrome) was found in 53.8% among PLHIV on ART , compared to 11.1% among ART naïve PLHIV(p= 0.001) .In the multivariate analysis, presence of metabolic syndrome was found to be directly associated with insulin resistance.

Objectives To determine the prevalence of subclinical synovitis in Lupus patients without peripheral joint symptoms, in those with arthralgias without arthritis and those with episodic arthritis but without radiological structural damage. Methods We conducted a multicentre cross-sectional study. Patients with lupus from those three categories were recruited to take part in a greyscale ultrasound scan performed by an expert blinded rheumatologist. Data from a historical control group from a previous study was also included for comparisons. Images were assessed separately in order to determine the presence and level of synovitis following Eular recommendations. Results Ninety-six patients (88.5% female) with an average age of 40 ± 6.2 years old, were included. SLICC/ACR score was 0.6 ± 0.3 in the group without joint symptoms (group 0), 0.8 ± 0.3 in the group with arthralgias (group I) and 1.1 ± 0.4 in the group with episodic arthritis. The global prevalence of subclinical synovitis was 38.5%. In group 0, that prevalence was 30%. The time since onset of symptoms of patients with subclinical synovitis was longer than the rest of the patients (9.4 ± 2.2 vs 6.5 ± 4.0 years, P < 0.001). No other remarkable association was founded with clinical features of the disease. Conclusions This is the first study focused on subclinical synovitis in patients with lupus. Other previous studies had included patients with different levels of arthropathy. Subclinical synovitis does exist in lupus patients in over a third of patients. Its meaning remains unclear and must be a topic of further studies.
