ABSTRACT
We present the first images of the v = 1 and v = 2 J = 1 → 0 SiO maser lines taken with KaVA, i.e., the combined array of the Korean Very Long Baseline Interferometry (VLBI) Network and the VLBI Exploration of Radio Astrometry (VERA), toward the OH/IR star WX Psc. The combination of long and short antenna baselines enabled us to detect a large number of maser spots, which exhibit a typical ring-like structure in both the v = 1 and v = 2 J = 1 → 0 SiO masers as those that have been found in previous VLBI observational results of WX Psc. The relative alignment of the v = 1 and v = 2 SiO maser spots are precisely derived from astrometric analysis, due to the absolute coordinates of the reference maser spot that were well determined in an independent astrometric observation with VERA. The superposition of the v = 1 and v = 2 maser spot maps shows a good spatial correlation between the v = 1 and v = 2 SiO maser features. Nevertheless, it is also shown that the v = 2 SiO maser spot is distributed in an inner region compared to the v = 1 SiO maser by about 0.5 mas on average. These results provide good support for the recent theoretical studies of the SiO maser pumping, in which both the collisional and the radiative pumping predict the strong spatial correlation and the small spatial discrepancy between the v = 1 and v = 2 SiO maser.

Authors: Pritchard Tracy J. , Perazzo Joseph D. , Holt Julie A. , Fishback Benjamin P. , McLaughlin Michaela , Bankston Karen D. , Glazer Greer 
Published: April 2016

Background:
Summer bridges facilitate the transition from high school to college. Although many schools employ summer bridges, few have published outcomes. This article's purpose is to share preconceptions of college by underrepresented and disadvantaged nursing students and describe important elements and long-term impact of a summer bridge, a component of the Leadership 2.0 program.

Method:
A longitudinal study design was used to collect baseline, short-term, and long-term post-summer bridge data. Methods included pre- and postsurveys, interviews, and focus groups.

Results:
After bridge completion, students felt more prepared for the nursing program. Students ranked socialization components as most important. The summer bridge had lasting impact through the first year, where grade point average and retention of underrepresented and disadvantaged bridge students was comparable to the majority first-year students.

Conclusion:

The summer bridge was effective in preparing nursing students for the first year of college. Through holistic evaluation, unique aspects of socialization critical to student success were uncovered. [

Authors: Brown Kate A. , Heath Jeffery Rachael C. , Bajuk Barbara , Shadbolt Bruce , Essex Rohan W. , Todd David A. 
Published: April 2016

Purpose:
To study the incidence and treatment of severe retinopathy of prematurity (ROP) in infants younger than 30 weeks' gestational age (GA) in New South Wales and the Australian Capital Territory, Australia, from 2003 to 2008. These data were then compared to data from previously reported epochs (1986 to 1987, 1992 to 1997, and 1998 to 2002).

Methods:
Data were divided into two sub-epochs (2003 to 2005 and 2006 to 2008) to study trends and combined to compare over 22 years.

Results:
From 2003 to 2008, 2,550 of 3,004 (84.9%) infants survived, 200 (7.8%) were diagnosed as having severe ROP, and 119 (59.5%) required laser therapy. No significant difference in the incidence of severe ROP or treatment rate in infants younger than 27 and 30 weeks' GA from 2003 to 2005 and 2006 to 2008 occurred. Similarly, between 1986 and 2008 there was no difference in the incidence of severe ROP. However, the treatment rate significantly increased during this time.

Conclusions:
The incidence of severe ROP has been stable since 1986. However, laser treatment significantly increased to include 8 infants with stage 2 ROP from 2003 to 2008.

Comparison of Transcorneal and Pars Plana Routes in Pediatric Cataract Surgery in Infants Using a 25-Gauge Vitrectomy System
Authors: Raina Usha K. , Bhambhwani Vishaal , Gupta Anika , Bhushan Gauri , Seth Anisha , Ghosh Basudeb 
Published: April 2016

Purpose:
To demonstrate and compare the performance of the 25-gauge transconjunctival sutureless vitrectomy system via anterior (transcorneal) and posterior (pars plana) routes in congenital cataracts in infants.

Methods:
In this prospective interventional study, 12 pediatric patients younger than 1 year with bilateral congenital cataract were included to undergo cataract surgery with posterior vitreorhexis and limited anterior vitrectomy using a 25-gauge vitrectomy system. One eye of each patient was operated on by the anterior (transcorneal) route and the other by the posterior (pars plana) route. All eyes were left aphakic. Intraoperative and postoperative (12 months after surgery) results were compared between the two routes, including visual axis opacification and astigmatism. All eyes were rehabilitated with contact lenses or spectacles.

Results:

The 25-gauge vitrectomy system allowed excellent intraoperative control in both groups. Postoperatively, there was minimal conjunctival congestion, corneal edema, and inflammatory reaction. No intra-operative or postoperative complications were noted in any eye. All eyes had a clear visual axis 12 months after surgery. Mean spherical equivalent was 15.50 ± 2.28 diopters (D) and mean astigmatism was 0.25 ± 0.45 D in the transcorneal group, whereas in the pars plana group it was 15.46 ± 2.45 D and 0.16 ± 0.39 D, respectively, at 12 months, the difference being statistically insignificant (
P
> .05).

Conclusions:
The 25-gauge vitrectomy system allows sutureless surgery with excellent intraoperative control and minimal postoperative inflammation and astigmatism with clear visual axis by both the transcorneal and pars plana routes.

Subjective Quality of Vision After Myopic LASIK: Prospective 1-Year Comparison of Two Wavefront-Guided Excimer Lasers
Authors: Yu Charles Q. , Manche Edward E. 
Published: April 2016

PURPOSE:
To compare subjective quality of vision between two wavefront-guided lasers in the treatment of myopia up to 1 year postoperatively.

METHODS:
In this prospective randomized study, 100 eyes of 50 patients were treated with wavefront-guided LASIK. One eye was treated with the WaveLight Allegretto Wave Eye-Q 400-Hz excimer laser (Alcon Laboratories, Inc., Hünenberg, Switzerland) and the other was treated with the VISX Star S4 IR CustomVue excimer laser (Abbott Medical Optics, Santa Ana, CA). Patients completed a questionnaire assessing quality of vision and visual symptoms preoperatively and at postoperative months 1, 3, 6, and 12.

RESULTS:

The Allegretto system demonstrated non-statistically significant superiority in several subjective parameters as early as 1 month after surgery. At 12 months, there was better clarity during the day (
P
= .001) in the Allegretto group. Subgroup analyses were performed on eyes with preoperative higher order aberrations of 0.3
µ
m or less and in patients with preoperative higher order aberrations greater than 0.3
µ
m. In subgroup analysis, there were no differences between the two systems in eyes with low higher order aberrations or high higher order aberrations. Patients did not express any preference for one system over the other when surveyed at 1 year postoperatively.

CONCLUSIONS:
One year after surgery, there were no differences in self-reported quality of vision outcomes with the exception of better clarity of vision during the day in the eyes treated with the Allegretto system. Patients did not express any preference for one treatment modality over the other.

Transepithelial Photorefractive Keratectomy for Hyperopia: A 12-Month Bicentral Study
Authors: Adib-Moghaddam Soheil , Arba-Mosquera Samuel , Walter-Fincke Roberta , Soleyman-Jahi Saeed , Adili-Aghdam Fatemeh 
Published: April 2016

PURPOSE:
To investigate the safety, efficacy, and stability of transepithelial photorefractive keratectomy (PRK) for hyperopia.

METHODS:
This interventional case series study at two sites included 55 eyes (31 patients) with hyperopia (0.50 to 6.00 diopters [D]), with or without astigmatism (0.00 to −3.00 D), that underwent one-step transepithelial PRK with a Amaris 500-Hz excimer laser (SCHWIND eye-tech-solutions, Kleinostheim, Germany). A 12-month follow-up was conducted. Preoperative and successive postoperative visual acuity, manifest refraction, haze, and other complication data were analyzed.

RESULTS:

The preoperative mean spherical equivalent of 2.56 ± 1.90 D improved to emmetropia (−0.08 ± 0.14 D) by 6 months, with subsequent slight mean regression of 0.024 D (range: −0.75 to 0.50) until month 12. Of the treated eyes, 75% and 76.2% were within the target refraction of ±0.50 D at 6 and 12 months postoperatively, respectively. The final mean cylindric refraction was comparable to the preoperative value (−0.94 ± 0.12 to −0.71 ± 0.12 D,
P
= .17); however, it was induced in 23% of eyes. The preoperative mean uncorrected distance visual acuity logMAR of 0.54 ± 0.05 significantly improved to 0.15 ± 0.03 by month 12 (
P
< .0001), and 64.2% of the treated eyes gained an uncorrected distance visual acuity of 20/25 or better. Ten eyes (23.8%) lost one line of preoperative corrected distance visual acuity (CDVA). No eye lost two or more lines of preoperative CDVA. Four eyes with a 3+ degree of haze were observed by the final visit. No other notable complications occurred. The low hyperopic eyes exhibited better overall results compared to the moderate hyperopic group.

CONCLUSIONS:
One-step transepithelial PRK with the Amaris 500-Hz excimer laser provided reasonable outcomes for the correction of hyperopia with or without mild to moderate astigmatism.

Very Late-Onset Corneal Scarring After Photorefractive Keratectomy Induced by Cataract Surgery
Authors: Fischinger Isaak , Seiler Theo G. , Zapp Daniel , Seiler Theo 
Published: April 2016

PURPOSE:
To report two cases with very late-onset scarring of the cornea after photorefractive keratectomy (PRK) induced by cataract surgery.

METHODS:
Case report and literature review.

RESULTS:
Two patients presented with a subepithelial corneal scar more than 20 years after PRK. Scarring occurred within the first few months after cataract surgery. Scar tissue was successfully removed by laser-assisted anterior lamellar keratoplasty.

CONCLUSIONS:
A few cases of late-onset corneal scarring after PRK have been described in the literature following trauma or ophthalmic surgery. Due to the need for cataract surgery in an aging population with previous PRK, this might become a more common problem.

Multi-Modal Longitudinal Evaluation of Subthreshold Laser Lesions in Human Retina, Including Scanning Laser Ophthalmoscope-Adaptive Optics Imaging
Authors: Wood Edward H. , Leng Theodore , Schachar Ira H. , Karth Peter A. 
Published: April 2016

BACKGROUND AND OBJECTIVE:
Subthreshold retinal laser therapy is efficacious for a variety of retinovascular disorders. Currently, it is unknown which laser parameters can ensure no detectable damage to human retina tissue.

MATERIALS AND METHODS:
One informed physician participant with a normal retina was treated with three levels (75%, 50%, and 25%) of subthreshold 577-nm laser (PASCAL; Topcon, Santa Clara, CA) at 20-millisecond (ms) duration and 100 µm spot size. Several high-resolution retinal imaging modalities, including spectral-domain optical coherence tomography (SD-OCT) and scanning laser ophthalmoscope-adaptive optics (SLO-AO), were used to longitudinally image retinal laser lesions during a 9-month period.

RESULTS:
SLO-AO and SD-OCT imaging of subthreshold laser therapy in human retina showed no cone cell or RPE damage at all time points during a 9-month period using the 25% threshold power 577-nm laser in the human retina.

CONCLUSION:
It is likely that subthreshold laser therapy with 577-nm laser at 20-ms duration in the human retina is safe at the 25% of threshold power level.

Hybrid 25- and 27-Gauge Vitrectomy for Complex Vitreoretinal Surgery
Authors: Yonekawa Yoshihiro , Thanos Aristomenis , Abbey Ashkan M. , Thomas Benjamin J. , Todorich Bozho , Faia Lisa J. , Williams George A. , Capone Antonio , Wolfe Jeremy D. , Hassan Tarek S. 
Published: April 2016

BACKGROUND AND OBJECTIVE:
The authors report the technique of using the 27-gauge (G) vitreous cutter through 25-G valved cannulas to allow hybrid instrumentation of both gauges.

PATIENTS AND METHODS:
Vitrectomy is initiated with standard placement of 25-G valved cannulas, followed by insertion of a 27-G vitreous cutter through the 25-G cannulas.

RESULTS:
The hybrid procedure emphasizes the advantages of both platforms: The 25-G cutter is more efficient for core vitrectomy and is more rigid to facilitate peripheral vitrectomy; the 25-G platform enjoys a wider armamentarium of instrumentation options; and the smaller profile of the 27-G cutter can be maneuvered more easily into tight surgical planes to act analogous to vertical scissors, with the added benefits of aspiration and spatula-like features. The authors illustrate this technique in three cases: diabetic tractional retinal detachment with dense plaques, posterior stage 4B retinopathy of prematurity, and sutureless scleral fixation of an intraocular lens.

CONCLUSIONS:
Hybrid use of the 25-G and 27-G platforms offers greater versatility for the management of complex vitreoretinal conditions.

Lingual Thyroid: A Case Series of Six Lingual Thyroid with Incidence and Different Treatment Modalities
Authors: Patil Yogesh Subhashsing , Rajashekhar Rashmi Prashant , Karodpati Nayanna Sanjay , Thomas James 
Published: April 2016

ABSTRACTObjectivesLingual thyroid (LT) is a rare embryological anomaly and originates from failure of the thyroid gland to descend from the foramen cecum to its normal eutopic prelaryngeal site. Lingual thyroid is the most frequent ectopic location of the thyroid gland. Its clinical incidence varies between 1:4000 and 1:10000. The purpose of this case series was to discuss a series of cases of LT gland its incidence, clinical presentation, sex ratio, age group, endocrine status, radiological features and appropriate surgical approaches.Materials and methodsSix patients of LT were diagnosed who presented to our institution in a period of 6 months out of 225 thyroid cases, out of 14539 outpatient department (OPD) patients. The LT is often asymptomatic but may cause dysphagia, dysphonia with stomatolalia, upper airway obstruction and hemorrhage, often with hypothyroidism. Treatment of a LT depends on the severity of symptoms, the age of the patient, any precipitating factors, such as puberty or pregnancy.ResultRelevant demographic, clinic-pathological and radiological data were recorded. Four of six were treated conservatively. One underwent complete surgical excision and one pregnant lady in first trimester kept under observation and regular follow-up.ConclusionWe found female predominance than male with ratio of 5:1. Our study had high prevalence of LT of 1:2400. Thyroid scintigraphy plays the most important role in diagnosing LT, but ultrasonography contributes as well. In cases of symptomatic disease, surgery is the treatment of choice, followed by radioiodine ablation and levothyroxine suppression therapy in more refractory cases.How to cite this articlePatil YS, Rajashekhar RP, Karodpati NS, Thomas J.

Solitary Trichoepithelioma of Nose: A Rare Case Report and Review of Literature
Authors: Shilpakar Sachin Lal , Aryal Bivek , Chettri Shyam Thapa , Pokharel Apar , Paudel Deepak 
Published: April 2016

ABSTRACTThe trichoepithelioma is a benign cutaneous neoplasm which is derived from hair follicles. It is common in the face, but there are only three reports of the solitary occurrence on the nose. It is often not recognized because of its rarity, controversial classification, origin and biological potential. The objective of this paper is to present a case of solitary trichoepithelioma on the nose, histopathological examination and treatment. It should be considered as a differential diagnosis of a solitary lesion of nose which is confused with basal cell carcinoma. The confirmation by histopathological examination is essential.How to cite this articleSah BP, Shilpakar SL, Aryal B, Chettri ST, Pokharel A, Mishra S, Paudel D.

A Rare Case of Sinonasal Extramedullary Plasmacytoma with Orbital Involvement
Authors: Chandrasekharan Ramanathan , Ashish Gaurav , Parmar Harshad 
Published: April 2016

ABSTRACT
Extramedullary plasmacytoma (EMP) is a rare entity in the head and neck region. It is phenotypically and immunologically different from multiple myeloma. Chronic transformation to multiple myeloma or its disseminated form is well known. It may even be the first manifestation of multiple myeloma also popularly known as secondary EMP.
We present a 43-year-old male patient with history of persistent progressive nasal obstruction with occasional epistaxis. Endoscopy revealed a right sinonasal mass which on excision biopsy was consistent with features of EMP.
Extramedullary plasmacytoma is a rare differential diagnosis for sinonasal mass. However, multiple myeloma should be ruled out via bone marrow examination, bone scan and serum and urine electrophoretic evaluation before arising at a diagnosis of EMP.
In spite of EMP of nasal cavity being a rare entity, it should be considered as one of the rare differential diagnoses.

Ultrasound-based Decision Making on Stimulation Protocol for Superovulated Intrauterine Insemination Cycles
Authors: Nagori Chaitanya 
Published: April 2016

ABSTRACTDeciding optimum stimulation protocols is one of the most important factors for the success of any assisted reproductive technologies. We have used ultrasound parameters chiefly with age and basal mass index (BMI) to decide stimulation protocols in intrauterine insemination (IUI) cycles. The parameters used on ultrasound were ovarian size (volume), number of antral follicles, ovarian stromal resistance index, and peak systolic velocity. A scoring system was developed according to the values of these parameters with age and BMI of the patient. This scoring system has been used to decide the dose of gonadotropins for superovulation in IUI cycles. It has been used for 1570 patients with cancellation of cycles due to poor response in only one patient and moderate ovarian hyperstimulation syndrome in only one patient. This shows that the scoring system has been very effective for deciding optimum stimulation protocols in patients with varying age, BMI, and ovarian reserve.How to cite this articlePanchal S, Nagori C.

Published: April 2016

ABSTRACTObjectiveThe aim of this study was to evaluate the pregnancy rates and outcomes in the patients with endometriosis after laparoscopic surgical management.Study designThis retrospective analytical study was done in patients diagnosed with endometriosis and who were managed by laparoscopic surgery at our hospital from January 2005 to December 2014. We evaluated pregnancy rates and outcomes in patients with endometriosis after laparoscopic surgical management.ResultsOut of total 140 eligible cases, 84 (60%) patients conceived and 56 (40%) did not conceive. Endometriosis was found to be in the minimal, mild, moderate, and severe stage in 19, 44, 57, and 20 patients respectively. In minimal, mild, moderate, and severe endometriosis, number of patients who conceived were 15 (78.95%), 27 (61.36%), 32 (56.14%), and 10 (50%) respectively. Out of 84 conceived patients, 39 (46.43%) conceived naturally, 25 (29.76%) conceived after controlled ovarian hyperstimulation (COH), intrauterine insemination (IUI), and 20 (23.81%) conceived afterin vitrofertilization (IVF). There were 54 (64.29%) term pregnancies, 16 (19.05%) preterm pregnancies, and 14 (16.67%) were spontaneous miscarriages in total.ConclusionThe pregnancy and live birth rates seem to be improved after laparoscopic surgical management of endometriosis. Reproductive outcome was closely associated with stage of endometriosis. A significant inverse correlation was observed between disease severity and spontaneous conception.How to cite this articleBettaiah R, Kurkuri SN, Gandubariki P.

Recurrent Empty Follicle Syndrome: A Rare Entity
Authors: Varma Thankam Rama 
Published: April 2016

ABSTRACTFailure to aspirate oocytes from apparently normally growing ovarian follicles with normal steroidogenesis after ovarian stimulation and meticulous follicular aspiration is referred to as empty follicle syndrome (EFS). It is a rare event in in vitro fertilization (IVF), but the economical consequences and emotional frustration of a cancelled cycle are enormous, as it causes substantial stress for both the patients and the treating physician. Here, we have reported one patient of recurrent EFS who had IVF in view of previous failed intrauterine inseminations, with normal male factor. Two cycles of controlled ovarian stimulation were done using antagonist protocol for this patient. However, as we were unable to retrieve any oocytes in both the cycles, we were offered her oocyte donation as the last resort.How to cite this articlePunhani R, Shankar K, Varma TR.
