Published: July 2014

AbstractThis prospective observational study was carried out to study the fetomaternal outcome in women with preterm premature rupture of membrane (PPROM) between 24 and 36 weeks of gestation.Materials and methodsA total of 150 pregnant women between 24 and 36 weeks gestation with PROM were subjected to detailed history and examination. Each patient was followed till her delivery and fetomaternal outcome was recorded gestation-wise between 24 and 28 weeks (n = 15), 28 and 32 weeks (n = 30), 32 and 34 weeks (n = 90), and 34 and 36 weeks (n = 15).ResultThe mean latency period from membrane rupture to delivery decreased from 15 days at 24 to 28 weeks, 11 days at 28 to 32 weeks to 4.4 days at 32 to 34 weeks to 2.1 days at 34 to 36 weeks. Majority of women delivered vaginally. The rate of spontaneous labor increased as the gestational age at admission increased, the difference between rate of spontaneous labor of 67% at 28 to 32 weeks and 86% at 34 to 36 weeks was statistically significant (p = 0.001). The indications for induction of labor were intrauterine fetal death, gross oligohydramnios, and clinical chorioamnionitis. The most common complication was clinical chorioamnionitis (6%) and postpartum sepsis (6%). The perinatal outcome was favorable in majority of cases and improved with the increase in gestational age at PROM. The overall perinatal mortality was 9.3%.ConclusionManagement of PPROM involves complete evaluation of risks and benefits of conservative management. Wherever possible, the treatment should be directed toward conserving the pregnancy with prophylactic use of antibiotics and steroids thereby reducing fetal-maternal morbidity and mortality. However, termination of pregnancy should be considered at the earliest suspicion of chorioamnionitis.How to cite this articleRana M, patra s, Puri M, Trivedi SS.

ABSTRACT

Aim
The aim of this study was to evaluate the fracture resistance of teeth submitted to several internal bleaching protocols using 35% hydrogen peroxide (35HP), 37% carbamide peroxide (37CP), 15% hydrogen peroxide with titanium dioxide nanoparticles (15HPTiO2) photoactivated by LED-laser or sodium perborate (SP).

Materials and methods
After endodontic treatment, fifty bovine extracted teeth were divided into five groups (n = 10): G1—unbleached; G2—35HP; G3—37CP; G4—15HPTiO2 photoactivated by LED-laser and G5—SP. In the G2 and G4, the bleaching protocol was applied in 4 sessions, with 7 days intervals between each session. In the G3 and G5, the materials were kept in the pulp teeth for 21 days, but replaced every 7 days. After 21 days, the teeth were subjected to compressive load at a cross head speed of 0.5 mm/min, applied at 135° to the long axis of the root using an eletromechanical testing machine, until teeth fracture. The data were submitted to ANOVA and Tukey tests (á = 5%).

Results
The 35HP, 37CP, 15HPTiO2 and SP showed similar fracture resistance teeth reduction (p > 0.05). All bleaching treatments reduced the fracture resistance compared to unbleached teeth (p < 0.05).

Conclusion
All bleaching protocols reduced the fracture resistance of endodontically-treated teeth, but there were no differences between each other.

Clinical significance
There are several internal bleaching protocols using hydrogen peroxide in different concentrations and activation methods. This study evaluated its effects on fracture resistance in endodontically-treated teeth.

Prosthetic Rehabilitation of Acquired Maxillary Defects Secondary to Mucormycosis: Clinical Cases
Authors: Shah Rupal J , Katyayan Preeti Agarwal 
Published: July 2014

ABSTRACTMaxillary necrosis can occur due to bacterial infections such as osteomyelitis, viral infections, such as herpes zoster or fungal infections, such as mucormycosis, aspergillosis etc. Mucormycosis is an opportunistic fungal infection, which mainly infects immunocompromised patients. Once the maxilla is involved, surgical resection and debridement of the necrosed areas can result in extensive maxillary defects. The clinician is to face many a challenge in order to replace not only the missing teeth, but also the lost soft tissues and bone, including hard palate and alveolar ridges. The prosthesis (Obturator) lacks a bony base and the lost structures of the posterior palatal seal area compromise retention of the prosthesis. Furthermore, the post surgical soft tissues are scarred and tense, which exert strong dislodging forces. The present article describes the prosthetic rehabilitation of maxillary necrosis secondary to mucormycosis in two cases, one completely edentulous and the other partially edentulous.How to cite this articleShah RJ, Katyayan MK, Katyayan PA, Chauhan V.

Bibliometric Indicators for Evaluating the Quality of Scientific Publications
Authors: Joshi Medha A 
Published: July 2014

ABSTRACT
Evaluation of quality and quantity of publications can be done using a set of statistical and mathematical indices called bibliometric indicators. Two major categories of indicators are (1) quantitative indicators that measure the research productivity of a researcher and (2) performance indicators that evaluate the quality of publications. Bibliometric indicators are important for both the individual researcher and organizations. They are widely used to compare the performance of the individual researchers, journals and universities. Many of the appointments, promotions and allocation of research funds are based on these indicators. This review article describes some of the currently used bibliometric indicators such as journal impact factor, crown indicator, h-index and it's variants. It is suggested that for comparison of scientific impact and scientific output of researchers due consideration should be given to various factors affecting theses indicators.

The Use of Matriderm and Autologous Skin Graft in the Treatment of Full Thickness Skin Defects
Authors: Min Jang Hwan , Yun In Sik , Lew Dae Hyun , Roh Tai Suk , Lee Won Jai 
Published: July 2014

Background For patients with full thickness skin defects, autologous Split-thickness skin grafts (STSG) are generally regarded as the mainstay of treatment. However, skin grafts have some limitations, including undesirable outcomes resulting from scars, poor elasticity, and limitations in joint movement due to contractures. In this study, we present outcomes of Matriderm grafts used for various skin tissue defects whether it improves on these drawbacks.
Methods From January 2010 to March 2012, a retrospective review of patients who had undergone autologous STSG with Matriderm was performed. We assessed graft survival to evaluate the effectiveness of Matriderm. We also evaluated skin quality using a Cutometer, Corneometer, Tewameter, or Mexameter, approximately 12 months after surgery.
Results A total of 31 patients underwent STSG with Matriderm during the study period. The success rate of skin grafting was 96.7%. The elasticity value of the portion on which Matriderm was applied was 0.765 (range, 0.635-0.800), the value of the trans-epidermal water loss (TEWL) was 10.0 (range, 8.15-11.00) g/hr/m2, and the humidification value was 24.0 (range, 15.5-30.0). The levels of erythema and melanin were 352.0 arbitrary unit (AU) (range, 299.25-402.75 AU) and 211.0 AU (range, 158.25-297.00 AU), respectively. When comparing the values of elasticity and TEWL of the skin treated with Matriderm to the values of the surrounding skin, there was no statistically significant difference between the groups.
Conclusions The results of this study demonstrate that a dermal substitute (Matriderm) with STSG was adopted stably and with minimal complications. Furthermore, comparing Matriderm grafted skin to normal skin using Cutometer, Matriderm proved valuable in restoring skin elasticity and the skin barrier.
Subunit Principle of Vulvar Reconstruction: Algorithm and Outcomes
Authors: Tan Bien-Keem , Kang Gavin Chun-Wui , Tay Eng Hseon , Por Yong Chen 
Published: July 2014

Background Vulvar defects result chiefly from oncologic resection of vulvar tumors. Reconstruction of vulvar defects restores form and function for the purpose of coitus, micturition, and defecation. Many surgical options exist for vulvar reconstruction. The purpose of this article is to present our experience with vulvar reconstruction.
Methods From 2007 to 2013, 43 women presented to us with vulvar defects for reconstruction. Their mean age at the time of reconstruction was 61.1 years. The most common cause of vulvar defect was from resection of vulvar carcinoma and extramammary Paget's disease of the vulva. Method s of reconstruction ranged from primary closure to skin grafting to the use of pedicled flaps.
Results The main complications were that of long term hypertrophic and/or unaesthetic scarring of the donor site in 4 patients. Twenty-two patients (51%) were able to resume sexual intercourse. There were no complications of flap loss, wound dehiscence, and urethral stenosis.
Conclusions We present a subunit algorithmic approach to vulvar reconstruction based on defect location within the vulva, dimension of the defect, and patient age and comorbidity. The gracilis and gluteal fold flaps are particularly versatile and aesthetically suited for reconstruction of a variety of vulvar defects. From an aesthetic viewpoint the gluteal fold flap was superior because of the well-concealed donor scar. We advocate the routine use of these 2 flaps for vulvar reconstruction.

Published: July 2014

Background Reconstruction of ischial pressure sore defects is challenging due to extensive bursas and high recurrence rates. In this study, we simultaneously applied a muscle flap that covered the exposed ischium and large bursa with sufficient muscular volume and a profunda femoris artery perforator fasciocutaneous flap for the management of ischial pressure sores.
Methods We retrospectively analyzed data from 14 patients (16 ischial sores) whose ischial defects had been reconstructed using both a profunda femoris artery perforator flap and a muscle flap between January 2006 and February 2014. We compared patient characteristics, operative procedure, and clinical course.
Results All flaps survived the entire follow-up period. Seven patients (50%) had a history of surgery at the site of the ischial pressure sore. The mean age of the patients included was 52.8 years (range, 18-85 years). The mean follow-up period was 27.9 months (range, 3-57 months). In two patients, a biceps femoris muscle flap was used, while a gracilis muscle flap was used in the remaining patients. In four cases (25%), wound dehiscence occurred, but healed without further complication after resuturing. Additionally, congestion occurred in one case (6%), but resolved with conservative treatment. Among 16 cases, there was only one (6%) recurrence at 34 months.
Conclusions The combination of a profunda femoris artery perforator fasciocutaneous flap and muscle flap for the treatment of ischial pressure sores provided pliability, adequate bulkiness and few long-term complications. Therefore, this may be used as an alternative treatment method for ischial pressure sores.
Proximal Interphalangeal Joint Dislocations and Treatment: An Evolutionary Process
Authors: Joyce Kenneth Michael , Joyce Cormac Weekes , Conroy Frank , Chan Jeff , Buckley Emily , Carroll Sean Michael 
Published: July 2014

Background Proximal interphalangeal joint (PIPJ) dislocations represent a significant proportion of hand clinic visits and typically require frequent follow-ups for clinical assessment, orthotic adjustments, and physiotherapy. There are a large number of treatment options available for PIPJ dislocations, yet no prospective or controlled studies have been carried out, largely due to the diversity of the various types of injuries.
Methods We retrospectively reviewed all the PIPJ dislocations in our institution over a five-year period and directly compared the different splinting techniques that we have used over this time frame.
Results There were a total of 77 dislocations of the PIPJ (57 men and 20 women) that were included in our study. We found that our management has shifted gradually from complete immobilisation to controlled early mobilisation with figure-of-eight splints. Following treatment, the range of motion of the PIPJ in the figure-of-eight group was significantly greater than that in the other three methods (P<0.05) used. There were significantly fewer hospital visits in the figure-of-eight splint group than in the other treatment groups.
Conclusions The treatment of PIPJ dislocations has undergone a significant evolution in our experience. Early controlled mobilisation has become increasingly important, and therefore, splints have had to be adapted to allow for this. The figure-of-eight splint has yielded excellent results in our experience. It should be considered for all PIPJ dislocations, but careful patient selection is required to achieve optimum results.
The Quality of Analysts’ Cash Flow Forecasts in China
Authors: Yao Jun , Meng Chenxing 
Published: July 2014

Abstract
There is a growing literature discussing the incentives of analysts to disseminate cash flow forecasts and the quality of these forecasts. Most studies support the ‘demand hypothesis’ and suggest that cash flow forecasts contain information additional to that provided in earnings forecasts. In contrast, Givoly et al. (2009) show that cash flow forecasts are just a simple extrapolation of analysts’ earnings forecasts. In response to this challenge, Call et al (2013) point out that the regression tests in Givoly et al (2009) are non-diagnostic due to the measurement problem contained in the US dataset. We suggest that Givoly et al. ’s (2009) method can be well applied in China since Chinese data do not have the same measurement problem as that contained in US data. By replicating the studies of Givoly et al. (2009) and Call et al. (2013), we find results consistent with Givoly et al. (2009) that analysts’ cash flow forecasts appear to be naïve extensions of their earnings forecasts in China.

ObjectivesTo determine whether volumetric contrast‐enhanced ultrasound (US) imaging has the potential to monitor changes in renal perfusion after vascular injury.MethodsVolumetric contrast‐enhanced US uses a series of planar image acquisitions, capturing the nonlinear second harmonic signal from microbubble contrast agents flowing in the vasculature. Tissue perfusion parameters (peak intensity [IPK], time to peak intensity [TPK], wash‐in rate [WIR], and area under the curve [AUC]) were derived from time‐intensity curve data collected during in vitro flow phantom studies and in vivo animal studies of healthy and injured kidneys. For the flow phantom studies, either the contrast agent concentration was held constant (10 μL/L) with varying volumetric flow rates (10, 20, and 30 mL/min), or the flow rate was held constant (30 mL/min) with varying contrast agent concentrations (5, 10, and 20 μL/L). Animal studies used healthy rats or those that underwent renal ischemia‐reperfusion injury. Renal studies were performed with healthy rats while the transducer angle was varied for each volumetric contrast‐enhanced US image acquisition (reference or 0°, 45°, and 90°) to determine whether repeated renal perfusion measures were isotropic and independent of transducer position. Blood serum biomarkers and immunohistology were used to confirm acute kidney injury.ResultsFlow phantom results revealed a linear relationship between microbubble concentrations injected into the flow system and the IPK, WIR, and AUC (R2 > 0.56; P < .005). Furthermore, there was a linear relationship between volume flow rate changes and the TPK, WIR, and AUC (R2 > 0.77; P < .005). No significant difference was found between the transducer angle during data acquisition and any of the perfusion measures (P > .60). After induction of renal ischemia‐reperfusion injury in the rat animal model (n = 4), volumetric contrast‐enhanced US imaging of the injured kidney revealed an initial reduction in renal perfusion compared to control animals, followed by progressive recovery of vascular function.ConclusionsVolumetric contrast‐enhanced US–based renal perfusion imaging may prove clinically feasible for detecting and monitoring acute kidney injury.
Sonography of the Lateral Antebrachial Cutaneous Nerve With Magnetic Resonance Imaging and Anatomic Correlation

Published: July 2014

ObjectivesAbnormalities of the lateral antebrachial cutaneous nerve (LABCN) are associated with antecubital elbow conditions, such as distal biceps brachii tendon tears and traumatic cephalic vein phlebotomy. These can lead to lateral forearm, elbow, and wrist symptoms that can mimic other disease processes. The purpose of this study was to characterize the sonographic appearance of the LABCN using cadaveric dissection and retrospective analysis of sonographic examinations of symptomatic patients with magnetic resonance imaging correlation.MethodsFor the first part of this study, a cadaveric elbow specimen was examined, and sonography was performed after dissection to identify the LABCN. Subsequently, 26 elbows in 13 patients with LABCN abnormalities were identified with sonography and retrospectively evaluated to characterize the appearance of the LABCN in both symptomatic and asymptomatic elbows.ResultsThe symptomatic LABCNs showed fusiform enlargement, increased echogenicity, and loss of the normal fascicular echo texture. The mean cross‐sectional area of the symptomatic nerves was 12.0 mm2 (range, 6.1–17.2 mm2), with a maximum thickness of 3.5 mm (range, 2.3–5.9 mm), compared to 3.3 mm2 (range, 1.9–5.2 mm2), with a maximum thickness of 1.3 mm (range, 0.9–2.2 mm), in the contralateral normal elbows.ConclusionsThe close proximity of the LABCN to the distal biceps tendon and the cephalic vein makes it vulnerable to compression and injury in the setting of distal biceps tendon tears and traumatic phlebotomy, which may cause nerve enlargement and increased echogenicity. Awareness of the location and appearance of the LABCN on sonography is important for determining potential causes of lateral elbow and forearm pain.
A physically based parameterization of gravity drainage for sea‐ice modeling
Authors: Rees Jones David W. , Worster M. Grae 
Published: July 2014

AbstractWe incorporate a physically derived parameterization of gravity drainage, in terms of a convective upwelling velocity, into a one‐dimensional, thermodynamic sea‐ice model of the kind currently used in coupled climate models. Our parameterization uses a local Rayleigh number to represent the important feedback between ice salinity, porosity, permeability, and desalination rate. It allows us to determine salt fluxes from sea ice and the corresponding evolution of the bulk salinity of the ice, in contrast to older, established models that prescribe the ice salinity. This improves the predictive power of climate models in terms of buoyancy fluxes to the polar oceans, and also the thermal properties of sea ice, which depend on its salinity. We analyze the behavior of existing fixed‐salinity models, elucidate the physics by which changing salinity affects ice growth and compare against our dynamic‐salinity model, both in terms of laboratory experiments and also deep‐ocean calculations. These comparisons explain why the direct effect of ice salinity on growth is relatively small (though not always negligible, and sometimes different from previous studies), and also highlight substantial differences in the qualitative pattern and quantitative magnitude of salt fluxes into the polar oceans. Our study is particularly relevant to growing first‐year ice, when gravity drainage is the dominant mechanism by which ice desalinates. We expect that our dynamic model, which respects the underlying physics of brine drainage, should be more robust to changes in polar climate and more responsive to rapid changes in oceanic and atmospheric forcing.
Relative role of El Niño and IOD forcing on the southern tropical Indian Ocean Rossby waves
Authors: Chakravorty Soumi , Gnanaseelan C. , Chowdary J. S. , Luo Jing‐Jia 
Published: July 2014

AbstractThe role of local air‐sea interactions over the tropical Indian Ocean (TIO) and remote forcing from the tropical Pacific Ocean in the formation and maintenance of southern TIO Rossby waves during El Niño and positive Indian Ocean Dipole (IOD) years is investigated. These Rossby waves are significantly intensified during the El Niño and IOD cooccurrence years, as compared to those during pure El Niño or IOD years. Coupled ocean‐atmosphere model sensitivity experiments reveal that air‐sea coupled processes in the TIO are responsible for the Rossby wave formation and its maintenance from boreal summer to fall, while remote forcing from the Pacific intensifies and maintains these waves up to the following spring. During the cooccurrence years, the Rossby waves are generated by both the persistent equatorial easterlies and off‐equatorial wind stress curl. During pure El Niño years, however, only off‐equatorial wind stress curl exists to drive weak Rossby wave. Asymmetric heating associated with IOD and the mean background easterly vertical wind shear (in the northern hemisphere) during summer and fall excite two symmetric anticyclones in both sides of the equator as atmospheric Rossby wave response, which are responsible for the anomalous equatorial surface easterlies. In contrast, symmetric heat sink over the Maritime Continent in winter associated with El Niño‐induced subsidence and mean easterly vertical shear (in southern hemisphere) are responsible for strong anticyclone in the southern TIO, which supports off‐equatorial wind stress curl.
