Authors: Reston EG , Bervian J , Kramer PF , Spiguel MH , Ferreira SH , Closs LQ 
Published: February 2014

SUMMARY
Oligodontia, or the congenital absence of teeth, can occur in isolation or as part of a syndrome. This study describes a case of isolated oligodontia associated with conical teeth and large diastemas in the anterior region. The patient was treated using direct composite resin restorations. Recent improvements in adhesive restorative materials allow practitioners to offer this low-cost, conservative esthetic treatment, which has the advantage of preserving sound dental structures, to patients with missing teeth.

Published: February 2014

SUMMARY

Purpose
To evaluate the fracture load and survival rate of weakened and non-weakened roots restored with different intracanal posts.

Methods
Eighty teeth (16 mm) were prepared to a length of 10 mm with a custom drill. Fifty roots were weakened with a tapered diamond drill, and 30 roots were not. The specimens were embedded with acrylic resin up to 3 mm from the coronal aspect, and the periodontal ligament was simulated. The 50 weakened roots were restored with (n=10) CPC-gold (cast post and core made of gold alloy), CPC-Ni (cast post and core made of Ni-Cr alloy), FP (glass fiber posts), FP-W (glass fiber posts with a wider coronal diameter), and FP-CR (fiber posts relined with composite resin). The 30 nonweakened roots were restored with (n=10) CPC-gold, CPC-Ni, and FP. All of the posts were adhesively cemented. All of the specimens were mechanically cycled (37°C, 45°, 130 N, 2.2 Hz, and 1.5 million pulses) and evaluated after every 5 × 104 cycles to evaluate the presence of cracks as a primary outcome (event). The specimens that survived cycling were subjected to a fracture load test (load application on the palatal aspect at a 45° inclination). Failure mode was classified as favorable (above the simulated bone level) and catastrophic (below the simulated bone level). Survival rates were estimated using the Kaplan-Meier method. Fracture load data were analyzed using the Kruskal-Wallis test (α=0.05) for weakened roots, one-way analysis of variance, and Tukey test (p&lt;0.05) for non-weakened roots, and Student t-test (p&lt;0.05) compared nonweakened vs weakened roots for the same post system.

Results
For the preliminary survival results, FP-W showed a higher survival rate when compared with CPC (gold/Ni). For the fracture load (N), the statistical analysis (p&lt;0.0001) presented differences among the weakened groups: CPC-gold (541.4) = CPC-Ni (642.6) &gt; FP (282.2) = FP-W (274.1) = FP-RC (216.6). No differences were observed for the groups that were nonweakened (majority of favorable failures): CPC-gold (459.3) = CPC-Ni (422.0) = FP (347.9). Weakened roots restored with CPC-gold promoted high values of load fracture and unfavorable failure rates.

Conclusion
Cast post and cores or fiber posts can be used for restoring nonweakened roots. However, for weakened roots, a fiber post with a wider cervical emerging diameter appears to be a better alternative when compared with cast post and cores.

Published: February 2014

SUMMARY

Purpose
To evaluate the survival rate, success rate, load to fracture, and finite element analysis (FEA) of maxillary central incisors and canines restored using ceramic veneers and varying preparation designs.

Methods and Materials
Thirty human maxillary central incisors and 30 canines were allocated to the following four groups (n=15) based on the preparation design and type of tooth: Gr1 = central incisor with a conservative preparation; Gr2 = central incisor with a conventional preparation with palatal chamfer; Gr3 = canine with a conservative preparation; Gr4 = canine with a conventional preparation with palatal chamfer. Ceramic veneers (lithium disilicate) were fabricated and adhesively cemented (Variolink Veneer). The specimens were subjected to 4 × 106 mechanical cycles and evaluated at every 500,000 cycles to detect failures. Specimens that survived were subjected to a load to fracture test. Bidimensional models were modeled (Rhinoceros 4.0) and evaluated (MSC.Patrans 2005r2 and MSC.Marc 2005r2) on the basis of their maximum principal stress (MPS) values. Survival rate values were analyzed using the Kaplan-Meier test (α = 0.05) and load to fracture values were analyzed using the Student t-test (α = 0.05).

Results
All groups showed 100% survival rates. The Student t-test did not show any difference between the groups for load to fracture. FEA showed higher MPS values in the specimens restored using veneers with conventional preparation design with palatal chamfer.

Conclusion
Preparation design did not affect the fracture load of canines and central incisors, but the veneers with conventional preparation design with palatal chamfer exhibited a tendency to generate higher MPS values.

Published: February 2014

Aims: The objective of the paper was to study the spectrum of gynecological disorders in HIV positive woman, which are often not given much importance as the issue of antiretroviral therapy and management of opportunistic infections occupy the major share of their treatment strategy. Methods: It was an observational study which included 135 women. The study was conducted in the Medical College and Hospital, Kolkata from January 2010 to December 2012 after obtaining permission from the institutional ethics committee. All the HIV positive women who came to the gynecological outpatient department with gynecological complaints were included in the study. Results: The seropositive women suffered from the same range of gynecological problems as in non-infected women. The most common complaints at presentation were vaginal white discharge and pruritus vulvae. The most common post-operative complication was fever. Conclusions: The HIV/AIDS is taking the shape of a generalized epidemic and with the advances in the antiretroviral therapy, the life expectancy of the patients is increasing. With the improvement of survival more and more of HIV positive women would present with problems pertaining to any system of the body and the gynecological complaint is not an exception. Addressing these problems would lead to boosting up of the care and support of this subset of women.Nepal Journal of Obstetrics and Gynaecology / Vol 8 / No. 2 / Issue 16 / July-Dec, 2013 / 21-25 DOI: http://dx.doi.org/10.3126/njog.v8i2.9761

Published: February 2014

Aims: This comparative study aimed to compare the efficacy of rectal misoprostol to oxytocin infusion in preventing primary postpartum haemorrhage after caesarean section. Methods: Fifty pregnant women with identifiable risk factors for post-partum haemorrhage who delivered baby by caesarean section were randomized to receive 600 μg rectal misoprostol and a placebo infusion intravenously or placebo rectally and a 20 iu oxytocin infusion. Post-operative blood loss four hours after surgery was estimated by application of pads of known weight. Results: The mean immediate four hours post-operative blood loss was not significantly different between the rectal misoprostol and oxytocin infusion group (100.08 ± 24.85 ml versus 108.20 ± 29.93 ml; p =0.144) and the change between the pre-operative and post-operative hematocrit was similar. Conclusions: Post-caesarean section rectal misoprostol has comparative efficacy to oxytocin infusion in preventing post-partum haemorrhage. It is recommended for use as alternative uterotonic in settings where there is low refrigeration capacity.Nepal Journal of Obstetrics and Gynaecology / Vol 8 / No. 2 / Issue 16 / July-Dec, 2013 / 34-37 DOI: http://dx.doi.org/10.3126/njog.v8i2.9767

Authors: Upadhyaya I , Chaudhary P 
Published: February 2014

Aims: Maternal morbidity occurs due to complications arising in pregnancy or within 42 days of delivery. Women with acute severe morbidity require admission in the intensive care unit (ICU). This study was done to explore the profile of those women requiring intensive care. Methods: A study was conducted at Paropakar Maternity and Women’s Hospital in which records of patients admitted in Maternal Intensive Care Unit (MICU) were evaluated for demographics, disease responsible for critical illness, complications that prompted MICU admissions, interventions required, length of MICU stay and resulting maternal morbidity and mortality. Results: Over the study period, 159 obstetric patients were transferred to MICU, representing 2.23% of 7109 deliveries. Hypertensive disorders of pregnancy (50%) and postpartum haemorrhage (14.46 %) were the two major obstetrical conditions responsible admission into MICU. Conclusions: Auditing of severe maternal morbidity will improve the quality of obstetric care and decrease the incidence of maternal morbidity and maternal mortality.Nepal Journal of Obstetrics and Gynaecology / Vol 8 / No. 2 / Issue 16 / July-Dec, 2013 / 38-41 DOI: http://dx.doi.org/10.3126/njog.v8i2.9768

Authors: Bhattachan K , Baral GN , Gauchan L 
Published: February 2014

Aims: The purpose of this study was to compare the efficacy of single combined dose of Cefotaxime and Metronidazole against conventional regimen of Ampicllin and Metronidazole for five days for the prevention of infectious morbidities in cesarean deliveries. Methods: This study was carried out at Paropakar Maternity and Women’s Hospital, Kathmandu from April to August 2011. Hundred patients, who had cesarean deliveries for various indications, were divided into two groups with fifty on each arm. Patients in group I were treated with intravenous single dose of Cefotaxime and Metronidazole after cord clamping, whereas those patients in group II were treated with Ampicillin and Metronidazole for five days. Efficacy of the treatment was compared in terms of postoperative infectious morbidities, duration of hospital stay and cost of antibiotics. Results: Overall ten cases (10%) had post-operative complications in which eight (8%) had infectious and two (2%) had thrombophlebitis. The infectious morbidities were febrile morbidities in four cases (4%) followed by urinary tract infection in three cases (3%) and wound infection in one case (1%). There was no statistically significant difference among distribution of these morbidities and in the mean duration hospital stay. The cost of single dose regimen was one-eighth of the multiple dose regimens which was statistically significant (p=0.000). Conclusions: Single dose of Cefotaxime and Metronidazole was equally effective as multiple doses of Ampicllin and Metronidazole for five days in prevention of infectious morbidities with benefit of cost.Nepal Journal of Obstetrics and Gynaecology / Vol 8 / No. 2 / Issue 16 / July-Dec, 2013 / 50-53 DOI: http://dx.doi.org/10.3126/njog.v8i2.9771

Authors: Jain M , Tripathi R , Jain S , Verma A , Bajpai N 
Published: February 2014

Rupture of gravid uterus due to torsion is a rare obstetric complication. The uterus has little mobility and is firmly held in place by its supports which resist any tendency of torsion. We are reporting a case of bicornuate uterus with rupture of left horn due to inability of malformed uterus to expand and axial torsion around one of its horns held by congenital band. Band was dissected and ruptured left horn excised, hemostasis was secured leaving the nonruptured nongravid horn of uterus intact.Nepal Journal of Obstetrics and Gynaecology / Vol 8 / No. 2 / Issue 16 / July-Dec, 2013 / 57-59 DOI: http://dx.doi.org/10.3126/njog.v8i2.9773

Published: February 2014

Primary papillary serous carcinoma of peritoneum (PPSCP) is a rare type of primary peritoneal adenocarcinoma and is clinico-histopathologically indistinguishable from primary ovarian papillary serous carcinoma. A 70 -year- female presented with pain abdomen of 4 months duration. On examination partially mobile vague mass was present in the suprapubic region. Exploratory laparotomy revealed normal right ovary and the left ovary showed simple cyst. Nodular, firm tumour was seen arising from omentum and measured 20x13x9.3 cm. Microscopically tumour was composed of large sheets of polygonal cells having large hyperchromatic and pleomorphic nuclei and moderate amount of eosinophilic cytoplasm forming cribriform pattern and papillae. It has similar prognosis as that of ovarian malignancy. This case of extraovarian papillary serous carcinoma of peritoneum (EPSCP) is presented here for its rarity.Nepal Journal of Obstetrics and Gynaecology / Vol 8 / No. 2 / Issue 16 / July-Dec, 2013 / 60-62 DOI: http://dx.doi.org/10.3126/njog.v8i2.9774
Double trouble: A Combined Ovarian and Axial Torsion of Uterus
Authors: Varadarajan R , Shivalingaiah N 
Published: February 2014

Torsion of the uterus is rare and mainly involves pregnant uterus. A combination of ovarian torsion with an axial torsion of uterus in a non-gravid woman is extremely rare. The exact incidence of uterine torsion is not clearly established, as only few case reports are available in the literature. Usually this kind of torsion are per operative diagnosis and very difficult to diagnose pre operatively. Here we present one such case with a combined ovarian and axial torsion of uterus.Nepal Journal of Obstetrics and Gynaecology / Vol 8 / No. 2 / Issue 16 / July-Dec, 2013 / 63-64 DOI: http://dx.doi.org/10.3126/njog.v8i2.9775

Experimental and Numerical Strength Analysis of Double Lap Joints Subjected to Tensile Loads
Authors: Adin Hamit , Temiz Şemsettin 
Published: February 2014

Abstract
In this paper the mechanical behaviour of double lap joints (DLJs) bonded with adhesive was analyzed. The stress-strain behaviour was investigated along the overlap length and adherend thickness in DLJs subjected to tensile loads. The stress analyses were performed by finite element method (FEM). The FEM calculations were performed using ANSYS (12.0.1). Experimental results were compared with the FEM results and were found to be quite reasonable. The results show that the failure loads are increased with an increase in adherend thickness. The stress-strain behaviour changes depending on adherend thickness and overlap length. Both FEM stress analyses and experimental results revealed that failure occurred around the edge zones of the overlap length due to the effect of shear stresses, while the failure at the edges of the adhesive layer originated from the peel stress in tensile.
Permeation of Chemical Substances through Polymeric Materials under Tension
Authors: Krzemińska Sylwia 
Published: February 2014

AbstractThe objective of the present work was to determine whether deformation of samples of barrier materials which protect from chemical permeation has an effect on breakthrough time. The tested materials included gloves made of chloroprene rubber, a fabric coated with butyl rubber, and a membrane made of butyl rubber. Permeation resistance was determined for 2 solvents, cyclohexane and ethyl acetate. It was found that depending on the type of material and solvent, the application of different tensile forces leads to different effects. The use of deformation variants (with tensile forces of 100 N or 200 N) did not significantly affect the breakthrough time of cyclohexane through the chloroprene membrane. On the other hand, the cyclohexane breakthrough time for the fabric coated with butyl rubber decreased by about 20 % at 200 N.

Published: February 2014

Abstract
Beneficiation of a deslimed, +0.038/−0.25 mm in size, phosphate ore containing carbonate fluorapatite (francolite), calcite, dolomite, and quartz by froth flotation is accomplished by a special approach based on conditioning the ore with a micro-emulsion consisting of 20 wt.- % Custafloat AR27 (collector, blend of fatty acid soaps and sulfates), 55 wt.- % No. 5 fuel oil and 25 wt.- % water at 70 wt.- % solid content and subsequent flotation after pulp dilution with water to 25 wt.- % solids. A good selectivity of separation was achieved at pH 8.5 and after 1.5 min conditioning time with micro-emulsion and flotation of the diluted pulp in the next 2 min. The maximum curvature of the upgrading Halbich grade-recovery curve indicated that the most efficient separation for the deslimed phosphate ore having 16.86 wt.- % P2O5 in the feed occurred at 0.6 kg/Mg providing concentrates containing 33 wt.- % P2O5 with P2O5 recovery equal to 70 wt.- %. The same flotation reagents used in a traditional way provided much worse concentrates containing 27 wt.- % P2O5 with recovery of 60 wt.- % at 0.9 kg/Mg of reagents.
The dispersal process of asexual propagules and the contribution to population persistence inMarchantia(Marchantiaceae)
Authors: Stieha Christopher R. , Middleton Aurea R. , Stieha Joseph K. , Trott Skylar H. , McLetchie D. Nicholas 
Published: February 2014

•Premise of the study:The dispersal process involves emigration from a focal source, dispersal through the landscape, and immigration into a new population or habitat. Despite the fact that dispersal is vital for the long‐term persistence of a species, key stages of the process are unknown or understudied for many species, including the importance and contribution of asexual reproduction. Focusing only on a single stage in the dispersal process may give an incomplete and potentially flawed picture of the effects of asexual reproduction on metapopulation dynamics in plant species.•Methods:Using a multifaceted approach that combines laboratory experiments, field studies, and mathematical models, we quantify the production, dispersal, and survival of immigrants of water‐dispersed asexual offspring (gemmae) of the clonal liverwortMarchantia inflexa.•Key results:Compared to female plants, male plants ofMarchantia inflexaproduce gemmae more quickly and in higher numbers, but due to desiccation have lower gemmae survival rates. Gemmae move up to 20 cm per minute in light rain, suggesting they can leave the source population. Long distance dispersal of gemmae is supported by the mathematical analysis of unisexual metapopulations. Upon reaching the new habitat, gemmae survival is high if they stay moist.•Conclusions:By integrating multiple experiments to quantify the effects of gemmae on metapopulation dynamics, we found that different stages of dispersal can lead to different conclusions on which sex has an advantage. Gemmae are critical for the maintenance of both sexes, the persistence of single‐sex metapopulations and species, and the invasibility of clonal organisms.
Isolation and characterization of microsatellite loci from Amur honeysuckle, Lonicera maackii (Caprifoliaceae)
Authors: Rocha Oscar J. , McNutt Erin , Barriball Kelly 
Published: February 2014

• Premise of the study: Lonicera maackii (Caprifoliaceae) is one of the most problematic invasive shrubs in forests of the eastern United States. Microsatellite markers could serve to test putative source‐sink relationships among populations to determine whether invasions progress along expanding fronts or through long‐distance dispersal events followed by local expansion.• Methods and Results: Eleven microsatellite loci were developed for Amur honeysuckle using a modified magnetic bead protocol. Six loci were screened across 158 individuals from seven populations and were shown to be variable, with the number of alleles per locus ranging from seven to 16. Observed heterozygosity ranged from 0.655 to 0.757. Five additional loci were screened using 68 individuals from three different populations, with seven to 12 alleles per locus and observed heterozygosity ranging from 0.682 and 0.831.• Conclusions: These microsatellite markers will help to elucidate the genetic structure and patterns of dispersal of L. maackii in its invasive range.
