Correlation of Ovarian and Stromal Volumes to Fasting and Postprandial Insulin Levels in Polycystic Ovarian Syndrome Patients
Authors: Nagori CB 
Published: July 2014

ABSTRACTBackgroundPatients with polycystic ovarian syndrome (PCOS) are believed to have large ovaries due to increased stroma. They also have derangement in luteinizing hormone (LH) and testosterone levels and high insulin resistance. As insulin resistance is thought to be associated with androgen and stromal excess, correlation was expected between insulin resistance and stromal excess.AimTo assess if ovarian and stromal volumes in PCOS patients have any correlation with fasting and postprandial insulin levels.Materials and methodsA prospective study of 153 subfertile patients was done over a period 18 months. After detailed history, clinical examination and informed consent of all patients were scanned by two-dimensional (2D) on day 3 of the cycle. Patients were divided into PCOS and non-PCOS groups according to Rotterdam criteria. Patients with hormonal derangements other than PCOS were excluded from the study.Patients were assessed by three-dimensional (3D) ultrasound (US) for ovarian and stromal volumes and fasting and postprandial insulin levels were checked on the same day.ResultsWith Pearson correlation significance level of 0.354 (2 tailed) correlation for ovarian volume to fasting insulin was 0.588, for ovarian volume to postprandial insulin was 0.523, for stromal volume to fasting insulin was 0.601, and for stromal volume to postprandial insulin was 0.523. No correlation could be established in non-PCOS group.ConclusionIn PCOS patients, a strong correlation was found between ovarian and stromal volume and fasting and post prandial insulin levels.How to cite this articlePanchal S, Nagori CB.

ABSTRACTProlactin (PRL) is hormone of multiple biological actions and is best known for its role in milk production. This hospital-based study was undertaken to review the impact of PRL hormone in vaginal delivery and cesarean delivery. Our study is meant to create awareness in the society to promote breast feeding and the importance of promoting normal vaginal delivery whenever possible. In this study, we investigated the serum PRL values using enzyme-linked immunoflow assay method in 101 women who underwent normal (56) and cesarean delivery (45) in obstetrics and gynecology department of Kannur Medical College, Anjarakandy. Serum PRL at 24 and 48 hours blood sample was estimated among the two groups, mean PRL in vaginal delivery 24 hours 359.46 ± 119.70 ng/ml, 48 hours 386.67 ± 135.66 ng/ ml and in cesarean delivery 24 hours 245.49 ± 115.49 ng/ml, 48 hours 282.92 ± 69.59 ng/ml. The values of serum PRL are found to be significantly higher in the vaginal delivery group (p < 0.001) as compared with the cesarean section group. Through this study, we concluded that the mothers who delivered by cesarean section had decreased PRL levels than the women who delivered vaginally which may have a significant role in establishment of breastfeeding.How to cite this articleManapatt AK, Anoop L, Tharammal D, Sathyapal A, Muneer Y.

Microwaves: A Revolution in Histoprocessing
Authors: Amrutha N 
Published: July 2014

ABSTRACT

Background and Aim
Pathologists are under constant pressure for instant and reliable diagnosis. The manual procedures employed in private laboratories and institutional setup for histoprocessing and staining are laborious and intense. Thus, this study aims to evaluate and compare the microwave tissue processing and staining with the conventional methods which are in vogue.

Materials and methods
Of the formalin fixed tissue biopsies received by our department, 30 specimens were randomly picked and subjected to grossing. Each specimen was cut into equal halves, each half was processed and stained by conventional method while the other by the microwave method. The entire procedure was blinded and evaluated by four observers based on the criteria of Mahesh Babu et al (2011): Cellular clarity, cytoplasmic details, nuclear detail and color intensity. The results were statistically analyzed using Chi square test and kappa.

Results
The overall time employed for microwave processing was 2 hours and for conventional methods it was 7 hours, while H and E staining by microwave process took 16 minutes and 45 seconds and it took 31 minutes and 20 seconds by the conventional process. The diagnostic ability of microwave method yielded promising results and was less time consuming.

Conclusion
Microwave processing and staining yielded quicker and better results compared to the routine methods. Therefore, Microwave can serve as a quicker and a reliable diagnostic method for a pathologist.

Evaluation of Mercury Contamination in Patients and Water during Amalgam Removal
Authors: Molina Gustavo Otoboni , Oliveira Marcelo Tomás , Constantino Henrique Vieira , Milioli Elysa , Ghizoni Janaina Salomon , Pereira Jefferson Ricardo 
Published: July 2014

ABSTRACT

Aim
The aim of this study was to evaluate mercury levels in wastewater and in patients during the removal of dental amalgam restorations.

Materials and methods
To test for mercury levels, patients were tested before and after amalgam restoration removal. To test for mercury emissions, samples of constant volume of wastewater from high-speed drills were collected before and during amalgam restoration removal.

Results
Although the systemic mercury levels were lower than the limit of biological tolerance, all patients had increased levels after dental restorations. All samples of wastewater had increased mercury levels too.

Conclusion
The urinary levels of mercury increased with dental amalgam removal using a high-speed drill. During the process of amalgam removal, water used for cooling the dental drill was contaminated with mercury.

Clinical significance
The mercury released by the physical action of the drill, the replacement material and especially the final destination of the amalgam waste can increase contamination levels that can be a risk for human and environment health.

The Inadequacy of the Y-axis of Growth (SNGn) for the Vertical Pattern Assessment in Patients with Sagittal Discrepancies
Authors: Paranhos Luiz Renato , Torres Fernando César , Brando Tiago Monteiro , Kaieda Armando K , Ramos Adilson Luiz 
Published: July 2014

ABSTRACT

Aim
The aim of this cephalometric study was to evaluate the influence of the sagittal skeletal pattern on the ‘Y-axis of growth’ measurement in patients with different malocclusions.

Materials and methods
Lateral head films from 59 patients (mean age 16y 7m, ranging from 11 to 25 years) were selected after a subjective analysis of 1630 cases. Sample was grouped as follows: Group 1 — class I facial pattern; group 2 — class II facial pattern; and Group 3 — class III facial pattern. Two angular measurements, SNGoGn and SNGn, were taken in order to determine skeletal vertical facial pattern. A logistic regression with errors distributed according to a binomial distribution was used to test the influence of the sagittal relationship (Class I, II, III facial patterns) on vertical diagnostic measurement congruence (SNGoGn and SNGn).

Results
Results show that the probability of congruence between the patterns SNGn and SNGoGn was relatively high (70%) for group 1, but for groups II (46%) and III (37%) this congruence was relatively low.

Conclusion
The use of SNGn appears to be inappropriate to determine the vertical facial skeletal pattern of patients, due to Gn point shifting throughout sagittal discrepancies.

Clinical Significance
Facial pattern determined by SNGn must be considered carefully, especially when severe sagittal discrepancies are present.

ABSTRACT

Aim
The present study was conducted with the aim of evaluating and comparing the shaping ability of two Nickel-titanium rotary instruments, with two disparate design features, on root canal geometry of extracted human maxillary first premolars using microcomputed tomography.

Study design
Twenty four bifurcated maxillary first premolars were divided into two groups and embedded in a rubber-based impression material. Both groups were submitted to microcomputed tomography before and after canal preparation (buccal and palatal) with either ProFile Vortex or Revo-S rotary instruments. Images were reconstructed and cross-sections corresponding to a distance 1, 2, 3, 4, 5, 6, and 7 mm from the anatomical apex were selected for canal transportation analysis. Volume changes were also measured.

Results
The degree and direction of canal transportation were non-significant for both instruments. Statistically significant differences were observed only between levels in the buccal canal in both groups. There was no significant difference between the two rotary systems in regards to the volume of dentin removed.

Conclusion
Our findings showed that ProFile Vortex and Revo-S instruments respected the original root canal anatomy and behaved similarly. ProFile Vortex rotary systems produced with innovative process were concluded to shape the upper maxillary premolar by leading minimal canal transportation, similar to Revo-S, rotary systems produced from traditional process.

ABSTRACTAimMental retardation (MR) subjects comprise a considerable amount of the community and are susceptible to oral and periodontal problems due to insufficient oral care. The aim of this cross-sectional study was to determine the oral health and periodontal status of MR patients in Turkey with regard to periodontal indices and Decay missed filling teeth (DMFT) scores and compare findings according to severity of the MR.Materials and methodsOne hundred and five MR patients were included to the study and divided into 3 groups according to MR severity diagnoses. Demographic variables like age, gender, disabled sibling, BMI, living an institution and clinical parameters like plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), missing teeth and DMFT scores were recorded from all subjects. Appropriate statistical analyses were used to compare the findings.ResultsThere were no statistically significant differences between groups according to age, gender, disabled sibling, living status and DMFT scores. Clinical periodontal indices and the number of missing teeth were showed a statistically significant increasing trend with the severity of MR (p < 0.05). Correlation analysis showed significant positive correlations between PI and periodontal disease measures like GI, PD, CAL and BOP and also between PI and DMFT (p < 0.05).ConclusionThe deteriorated teeth condition and deprived periodontal health of MR patients may be most likely caused by the poor oral hygiene and may be worsen with the severity of the MR.Clinical significanceKnowledge of oral and periodontal status of mental retardation patients has great importance for public health and family education.How to cite this articleOzgul O, Dursun E, Ozgul BM, Kartal Y, Coskunses FM, Kocyigit ID, Tözüm TF.

Published: July 2014

ABSTRACT

Purpose
To analyze on scanning electron microscopy (SEM) pictures from eight composite resins, taken in the centers of the initial, the middle and the terminal thirds of in vitro produced wear tracks morphological features to explain causative mechanisms for the material wear observed under two- and three-body wear.

Materials and methods
In vitro wear behavior of eight composite resins, three conventional and five nanofiller containing marketed products was evaluated using a custommade Zr-ball-on-disk sliding device. The composite specimens were subjected to 50,000 one-way sliding cycles (1.2 Hz, 50 N load), either simulating two-body wear with water as the intermediate medium or three-body wear using aqueous suspensions of polymethyl methacrylate (PMMA) beads and poppy seeds, respectively. Volume loss of the materials was determined in previous study. Representative specimens were selected for inspection by scanning electron microscopy at 500-fold magnification. From each of the 24 wear tracks microphotographs were taken in the central deepest parts of the initial, middle and terminal thirds of the tracks.

Results
For most materials morphological differences were detected depending on the location within the wear track. As a rule, the surface deterioration found increased toward the final part of the wear scar. According to common classification in tribology abrasive wear and fatigue wear, or a combination of both mechanisms were found for all materials tested. Wear was dependent both on the testing mode and on the composition of the individual composite resin material.

Conclusion
The morphological assessment of wear tracks reflects the nature of the abrasive and reveals insight into the mechanism generating wear patterns. Morphological details confirmed abrasive and fatigue-related wear as main failure mechanisms. Selection of food-like slurries as third-body media, such as poppy seed suspension is mandatory to simulate wear of composite restorations in occlusal cavities where three-body wear is the dominating determinant of loss of substance and surface deterioration.

ABSTRACT

Aim
The aim of the present study was to determine the success rate after 12 months of follow-up in a series of cases in which chemo-mechanical caries removal (CMCR) was performed with PapacarieTM, followed by restoration with glass ionomer cement.

Background
The development of conservative techniques for carious tissue removal and improvements in dental restoration materials have allowed better preservation of dental structures in the treatment of decayed teeth. Chemo-mechanical caries removal (CMCR) is a conservative atraumatic treatment option. PapacarieTM is a papain-based material developed to act only on the carious dentin, allowing its easy removal with a blunt curette.

Case report
The study involved a total of 84 deciduous posterior teeth with occlusal dentinal caries. Only teeth without risk of pulp exposure were studied. After a period of 12 months, the restorations were evaluated based on criteria employed in previous studies. The radiographic evaluation revealed resorption and calcification of the affected teeth. The data were submitted to descriptive statistical analysis with the aid of the XLSTAT program. The success rate was 88.1% and 98.8% based on the clinical and radiographic evaluations, respectively. The difference between the success and failure rates was statistically significant (p < 0.0001).

Conclusion
PapacarieTM is an effective product for CMCR on occlusal dentinal tissue in deciduous teeth, demonstrating a high clinical and radiographic success rate after 12 months of follow-up.

Platybasia in 22q11.2 Deletion Syndrome Is Not Correlated with Speech Resonance
Authors: Spruijt Nicole E , Kon Moshe , Mink van der Molen Aebele B 
Published: July 2014

Background An abnormally obtuse cranial base angle, also known as platybasia, is a common finding in patients with 22q11.2 deletion syndrome (22q11DS). Platybasia increases the depth of the velopharynx and is therefore postulated to contribute to velopharyngeal dysfunction. Our objective was to determine the clinical significance of platybasia in 22q11DS by exploring the relationship between cranial base angles and speech resonance.Methods In this retrospective chart review at a tertiary hospital, 24 children (age, 4.0-13.1 years) with 22q11.2DS underwent speech assessments and lateral cephalograms, which allowed for the measurement of the cranial base angles.Results One patient (4%) had hyponasal resonance, 8 (33%) had normal resonance, 10 (42%) had hypernasal resonance on vowels only, and 5 (21%) had hypernasal resonance on both vowels and consonants. The mean cranial base angle was 136.5° (standard deviation, 5.3°; range, 122.3-144.8°). The Kruskal-Wallis test showed no significant relationship between the resonance ratings and cranial base angles (P=0.242). Cranial base angles and speech ratings were not correlated (Spearman correlation=0.321, P=0.126). The group with hypernasal resonance had a significantly more obtuse mean cranial base angle (138° vs. 134°, P=0.049) but did not have a greater prevalence of platybasia (73% vs. 56%, P=0.412).Conclusions In this retrospective chart review of patients with 22q11DS, cranial base angles were not correlated with speech resonance. The clinical significance of platybasia remains unknown.

Published: July 2014

Background Perforations in the nasal septum (NSP) give rise not only to disintegration of the septum anatomy but also impairment in normal nasal physiology. The successes of these surgical techniques are usually equated to anatomical closure of the perforation. The goal of this study is to evaluate the subjective and objective results of our surgical technique for septal perforation surgery.
Methods All NSPs in the six patients were closed by inferior turbinate flap. The Nasal Obstruction Symptom Evaluation (NOSE) instrument was used to evaluate the preoperative and postoperative subjective sensation of nasal obstruction. Measurement of preoperative and postoperative nasal airway resistance was performed using active anterior rhinomanometry which is an objective test. Wilcoxson signed rank test and Spearman correlation test were used to analyze correlation between NOSE scores and rhinomanometric measurements.
Results The full closure of the septal perforations was noted in 100% of patients. The total NOSE score was 14 preoperatively and one postoperatively. The improvement in NOSE scores was statistically significant (P≤0.002). The mean preoperative total resistance (ResT150) value was 0.13 Pa/cm3s-1, which is below the normal range (0.16-0.31 Pa/cm3s-1), while the mean postoperative ResT150 value was 0.27 Pa/cm3s-1. The correlation between the improvement in NOSE scores and improvements in ResT150 values was statistically significant.
Conclusions Surgical approaches should aim to solve both the anatomical and physiological problems of NSP. The application of subjective and objective tests in the postoperative period will help surgeons assess the applied techniques.
Prevention of Implant Malposition in Inframammary Augmentation Mammaplasty
Authors: Kim Yoon Ji , Kim Yang Woo , Cheon Young Woo 
Published: July 2014

Background Implant malposition can produce unsatisfactory aesthetic results after breast augmentation. The goal of this article is to identify aspects of the preoperative surgical planning and intraoperative flap fixation that can prevent implant malposition.
Methods This study examined 36 patients who underwent primary dual plane breast augmentation through an inframammary incision between September 1, 2012 and January 31, 2013. Before the surgery, preoperative evaluation and design using the Randquist formula were performed. Each patient was evaluated retrospectively for nipple position relative to the breast implant and breast contour, using standardized preoperative and postoperative photographs. The average follow-up period was 10 months.
Results Seven of 72 breasts were identified as having implant malposition. These malpositions were divided into two groups. In relation to the new breast mound, six breasts had an inferiorly positioned and one breast had a superiorly positioned nipple-areolar complex. Two of these seven breasts were accompanied with an unsatisfactory breast contour.
Conclusions We identified two main causes of implant malposition after inframammary augmentation mammaplasty. One cause was an incorrect preoperatively designed nipple to inframammary fold (N-IMF) distance. The breast skin and parenchyma quality, such as an extremely tight envelope, should be considered. If an extremely tight envelope is found, the preoperatively designed new N-IMF distance should be increased. The other main cause of malposition is failure of the fascial suture from Scarpa's fascia to the perichondrium through an inframammary incision. As well, when this fixation is performed, it should be performed directly downward to the perichondrium, rather than slanted in a cranial or caudal direction.
