To describe postoperative complications encountered in the Primary Tube Versus Trabeculectomy (PTVT) Study during 5 years of follow-up.Multicenter randomized clinical trial.A total of 242 eyes of 242 patients with medically uncontrolled glaucoma and no previous incisional ocular surgery, including 125 patients in the tube group and 117 patients in the trabeculectomy group.Patients were enrolled at 16 clinical centers and randomly assigned to treatment with a tube shunt (350-mmSurgical complications, reoperations for complications, visual acuity, and cataract progression.Early postoperative complications occurred in 24 patients (19%) in the tube group and 40 patients (34%) in the trabeculectomy group (P = 0.013). Late postoperative complications developed in 27 patients (22%) in the tube group and 32 patients (27%) in the trabeculectomy group (P = 0.37). Serious complications producing vision loss and/or requiring a reoperation were observed in 3 patients (2%) in the tube group and 9 patients (8%) in the trabeculectomy group (P = 0.11). Cataract progression was seen in 65 patients (52%) in the tube group and 52 patients (44%) in the trabeculectomy group (P = 0.30). Surgical complications were not associated with a higher rate of treatment failure (P = 0.61), vision loss (P = 1.00), or cataract progression (P = 0.77) CONCLUSIONS: A large number of surgical complications were observed in the PTVT Study, but most were transient and self-limited. The incidence of early postoperative complications was higher following trabeculectomy with MMC than with tube shunt surgery. The rates of late postoperative complications, serious complications, and cataract progression were similar with both surgical procedures after 5 years of follow-up. Surgical complications did not increase the risk of treatment failure, vision loss, or cataract progression.

To report 5-year treatment outcomes in the Primary Tube Versus Trabeculectomy (PTVT) Study.Multicenter randomized clinical trial.A total of 242 eyes of 242 patients with medically uncontrolled glaucoma and no previous incisional ocular surgery, including 125 patients in the tube group and 117 patients in the trabeculectomy group.Patients were enrolled at 16 clinical centers and randomly assigned to treatment with a tube shunt (350-mmThe primary outcome measure was the rate of surgical failure, defined as intraocular pressure (IOP)21 mmHg or reduced20% from baseline, IOP ≤ 5 mmHg, reoperation for glaucoma, or loss of light perception. Secondary outcome measures included IOP, glaucoma medical therapy, and visual acuity.The cumulative probability of failure after 5 years of follow-up was 42% in the tube group and 35% in the trabeculectomy group (P = 0.21; hazard ratio = 1.31; 95% confidence interval = 0.86-2.01). At 5 years, IOP (mean ± standard deviation) was 13.4 ± 3.5 mmHg in the tube group and 13.0 ± 5.2 mmHg in the trabeculectomy group (P = 0.52), and the number of glaucoma medications (mean ± standard deviation) was 2.2 ± 1.3 in the tube group and 1.3 ± 1.4 in the trabeculectomy group (P0.001).Trabeculectomy with MMC and tube shunt surgery produced similar IOPs after 5 years of follow-up in the PTVT Study, but fewer glaucoma medications were required after trabeculectomy. No significant difference in the rate of surgical failure was observed between the 2 surgical procedures at 5 years.

- Abstract
The primary objective of this research was to investigate nutritional composition of soybean, canola, cottonseed, palm and rapeseed oils under and the effect of storage conditions on their oxidative stability. Nutritional quality of selected seed oils was determined in term of fatty acids, tocopherols and tocotrienols compositions, total phenolic, total flavonoids and mineral contents. High resolution gas chromatography (HR-GC) analysis showed the presence of saturated, monounsaturated and polyunsaturated fatty acids having range from 9.21-43.25, 27.01-58.87 and 29.23-57.75 g/100g, respectively in all the oils. High performance liquid chromatography (HPLC) analysis revealed that γ-tocopherol was the major tocopherol followed by α-tocopherol in most of the oils. Spectrophotometric analysis showed that the total phenolic contents were 2.84-14.44 mg/g of oil, measured as gallic acid equivalent and total flavonoid contents were 0.44-1.56 mg/g of oil, measure as quercetin equivalent. Inductively coupled plasma-optical emission spectrophotometer analysis revealed that Mg, Fe and Mn were present in higher concentration ranging from 57.14-114.85, 126.87-460.06 and 106.85-538.39 μg/ml respectively. For study the effect of various storage conditions on the oxidation parameters, free fatty acid, peroxide value, para-anisidine value, conjugated dienes and trienes values were determined and ranging from 0.48-1.65, 10.65-40.15 meq/kg, 9.98-33.30, 8.74-28.41 and 3.86-15.02, respectively after 90 days storage. Statistical analysis revealed that various storage conditions exerted significant (p ≤ 0.05) effect on the oxidative stability of selected oils to different extent., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2024 Ahmed et al.

- Abstract
The attention to polymer-based biomaterials, for instance, chitosan and its derivatives, as well as the techniques for using them in numerous scientific domains, is continuously rising. Chitosan is a decomposable naturally occurring polymeric material that is mostly obtained from seafood waste. Because of its special ecofriendly, biocompatible, non- toxic nature as well as antimicrobial properties, chitosan-based materials have received a lot of interest in the field of biomedical applications. The reactivity of chitosan is mainly because of the amino and hydroxyl groups in its composition, which makes it further fascinating for various uses, including biosensing, textile finishing, antimicrobial wound dressing, tissue engineering, bioimaging, gene, DNA and drug delivery and as a coating material for medical implants. This study is an overview of the different types of chitosan-based materials which now a days have been fabricated by applying different techniques and modifications that include etherification, esterification, crosslinking, graft copolymerization and o-acetylation etc. for hydroxyl groups' processes and acetylation, quaternization, Schiff's base reaction, and grafting for amino groups' reactions. Furthermore, this overview summarizes the literature from recent years related to the important applications of chitosan-based materials (i.e., thin films, nanocomposites or nanoparticles, sponges and hydrogels) in different biomedical applications., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

- Abstract
International medical graduates (IMGs) tend to choose careers in geriatric psychiatry likely because high-quality training and robust mentorship opportunities from other IMGs are available. Geriatric psychiatry offers stable career prospects and opportunities to express humanitarian impulses by working closely with elders. IMGs currently constitute almost a quarter of the psychiatry workforce and approximately 53% of the geriatric psychiatry work force in the United States. However, the number of IMGs entering psychiatry residencies-and, subsequently, geriatric psychiatry fellowships-has recently declined. Overreliance on IMGs in the US geriatric psychiatric workforce means these shortages will further burden an already-limited geriatric mental health care workforce and further compromise US health system capacity to meet its elders' needs., (Copyright 2023 American Medical Association.

- Abstract
Objective: To explore the utility of the Catquest 9SF visual function (VF) questionnaire along with visual acuity (VA) for determining appropriateness and priority for cataract surgery. To evaluate the feasibility of administering the Catquest-9SF in a clinical setting using web-based electronic data capture and interpretation., Design: Prospective multicentred interventional observational study., Participants: Subjects undergoing sequential cataract surgery in both eyes at 4 sites in Ontario., Methods: We recorded best-corrected VA (BCVA) and VA with current correction (CCVA) in each eye and both eyes (OU) and Catquest-9SF responses on a tablet before and after cataract surgery. Linear regression models were employed to test for associations between VA and visual function (VF)., Results: Preoperative BCVA and CCVA in the worse eye were significant predictors of change in VF (p = 0.006 and p = 0.008, respectively); subjects with worse VA had a greater improvement in VF after surgery. There was a significant association between improvement in VF and improvement in CCVA OU (p = 0.001). Fourteen of 151 subjects (9%) had no improvement or worse VF scores after surgery. Within this group, 10 of 14 subjects had a preoperative score ≤-3, which is suggestive of minimal visual disability. Within this subset, 4 of 14 subjects (2.6%) had a preoperative BCVA of 20/30 or better in their worse eye., Conclusions: For patient groups with equal VA, the Catquest-9SF score can help determine priority for surgery. Web-based data capture and interpretation allow for efficient virtual assessments of VF. A BCVA in the worse eye of 20/30 or better combined with a Catquest-9SF score <-3 can be used as a guideline for lowest priority., (Copyright © 2022 Canadian Ophthalmological Society.

- Abstract
Accessibility to clean drinking water often remains a crucial task at times. Among other water pollutants, arsenic is considered a more lethal contaminant and has become a serious threat to human life globally. This review discussed the sources, chemistry, distribution, and toxicity of arsenic and various conventional technologies that are in option for its removal from the water system. Nowadays, biosorbents are considered the best option for arsenic-contaminated water treatment. We have mainly focused on the need and potential of biosorbents especially the role of chitosan-based composites for arsenic removal. The chitosan-based sorbents are economically more efficient in terms of their, low toxicity, cost-effectiveness, biodegradability, eco-friendly nature, and reusability. The role of various modification techniques, such as physical and chemical, has also been evaluated to improve the physicochemical properties of biosorbent. The importance of adsorption kinetic and isotherm models and the role of solution pH and pH
PZC for arsenic uptake from the polluted water have also been investigated. Some other potential applications of chitosan-based biosorbents have also been discussed along with its sustainability aspect. Finally, some suggestions have been highlighted for further improvements in this field., (© 2022.

- Abstract
Acute liver injury is a common disease without effective therapy in humans. We sought to evaluate a combination therapy of insulin-like growth factor 1 (IGF-I) and BTP-2 in a mouse liver injury model induced by lipopolysaccharide (LPS). We chose this model because LPS is known to increase the expression of the transcription factors related to systemic inflammation (i.e., NFκB, CREB, AP1, IRF 3, and NFAT), which depends on calcium signaling. Notably, these transcription factors all have pleiotropic effects and account for the other observed changes in tissue damage parameters. Additionally, LPS is also known to increase the genes associated with a tissue injury (e.g., NGAL, SOD, caspase 3, and type 1 collagen) and systemic expression of pro-inflammatory cytokines. Finally, LPS compromises vascular integrity. Accordingly, IGF-I was selected because its serum levels were shown to decrease during systemic inflammation. BTP-2 was chosen because it was known to decrease cytosolic calcium, which is increased by LPS. This current study showed that IGF-I, BTP-2, or a combination therapy significantly altered and normalized all of the aforementioned LPS-induced gene changes. Additionally, our therapies reduced the vascular leakage caused by LPS, as evidenced by the Evans blue dye technique. Furthermore, histopathologic studies showed that IGF-I decreased the proportion of hepatocytes with ballooning degeneration. Finally, IGF-I also increased the expression of the hepatic growth factor (HGF) and the receptor for the epidermal growth factor (EGFR), markers of liver regeneration. Collectively, our data suggest that a combination of IGF-I and BTP-2 is a promising therapy for acute liver injury., (© 2022 The Authors.

- Abstract
Objective: The introduction of the Milestone Project underscored the need for objective assessments of resident progress across the competencies. Therefore, the authors examined the Psychiatry Resident-In-Training Examination (PRITE) utility for measuring improvements in medical knowledge (MK)., Methods: The authors compared the mean performance for each MK subcompetency by resident year for all residents taking the PRITE from 2015 to 2017 (18,175 examination administrations). In addition, they surveyed psychiatry residency program directors regarding how well they thought they teach these subcompetencies., Results: Increases in MK subcompetencies by resident year were significant for Psychopathology (p < 0.003), Psychotherapy (p < 0.002), and Somatic Therapies (p < 0.000). Development, Clinical Neuroscience, and Practice of Psychiatry did not show statistically significant differences between postgraduate years. Eighty psychiatry program directors responded to the survey and felt optimistic about their ability to teach the Psychopathology, Psychotherapy, Somatic Therapies, and Practice of Psychiatry subcompetencies., Conclusions: The PRITE measured significant improvements in medical knowledge for several of the core subcompetencies. The program director's responses would suggest that the lack of statistically significant differences found for Development and Clinical Neuroscience reflects areas in need of curricular development. The disparity between PRITE performance and program director perception of the Practice of Psychiatry subcompetency may reflect difficulties in defining the scope of this subcompetency. Overall, this suggests that structured examinations help measure improvements in certain subcompetencies and may also help identify curricular needs. However, there may be potential problems with the definition of some subcompetencies., (© 2021. Academic Psychiatry.)

- Abstract
Increasing reports have appeared of pleural effusion and peripheral eosinophilia associated with clozapine treatment. These reports describe the onset of pleural effusion from 2 to 5 weeks after initiation of clozapine. Here, we describe a case of a 28-year-old Chinese male who presented with pleural effusion and peripheral eosinophilia ∼17 weeks after initiation of clozapine. We discuss this delayed presentation and examine the potential significance of the patient's East Asian ethnicity. We recommend clinicians consider ethnicity and other factors that can affect the metabolism of clozapine when choosing a clozapine titration schedule and when monitoring during clozapine treatment., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

- Abstract
This study evaluates the kinetic hydrate inhibition (KHI) performance of four quaternary ammonium hydroxides (QAH) on mixed CH
4 + CO2 hydrate systems. The studied QAHs are; tetraethylammonium hydroxide (TEAOH), tetrabutylammonium hydroxide (TBAOH), tetramethylammonium hydroxide (TMAOH), and tetrapropylammonium hydroxide (TPrAOH). The test was performed in a high-pressure hydrate reactor at temperatures of 274.0 K and 277.0 K, and a concentration of 1 wt.% using the isochoric cooling method. The kinetics results suggest that all the QAHs potentially delayed mixed CH4 + CO2 hydrates formation due to their steric hindrance abilities. The presence of QAHs reduced hydrate formation risk than the conventional hydrate inhibitor, PVP, at higher subcooling conditions. The findings indicate that increasing QAHs alkyl chain lengths increase their kinetic hydrate inhibition efficacies due to better surface adsorption abilities. QAHs with longer chain lengths have lesser amounts of solute particles to prevent hydrate formation. The outcomes of this study contribute significantly to current efforts to control gas hydrate formation in offshore petroleum pipelines.- Published

- Abstract
Purpose: To review evidence and provide guidelines on intracameral (ICM) injection techniques and monitoring., Materials and Methods: A review of published literature on ICM injection and intravitreal injections formed the basis for roundtable deliberations by an expert panel of ophthalmologists., Results: ICM injection as a way to deliver medications is growing in popularity. However, there is limited published literature and no standard approach to best practices for ICM injections, particularly when not accompanying another surgical procedure. Fortunately, there is long clinical experience with ICM manipulation and a large body of evidence surrounding intravitreal injections that has provided important guidance. The expert panel formulates several concrete guidelines and many suggested techniques to help physicians safely and effectively employ ICM injections., Conclusions: This committee addressed the many considerations surrounding ICM injection of drugs or implants and agree that it is a safe and effective surgical procedure when performed with appropriate training and according to established safe practices.

- Abstract
Clozapine is a second-generation antipsychotic typically reserved for refractory psychotic disorders due to its high-risk side effect profile to include agranulocytosis, with its attendant need for regular blood draws. While reports of extrapyramidal symptoms (EPS), including acute dystonic reactions, are exceedingly rare, we present the case of a 44-year-old male with a long-standing history of treatment-resistant schizoaffective disorder and no history of EPS who experienced an acute buccal dystonic reaction in the setting of clozapine initiation and discontinuation of depot and oral risperidone. This case report presents one of the few documented episodes of acute dystonic reactions occurring in the setting of clozapine administration. Based upon the patient's history and the dosing time line of the medications, we propose that an interaction between the clozapine and residual risperidone was responsible for the development of the acute buccal dystonia.

- Abstract
Our older physicians, an increasing number of those in practice, constitute a valuable human resource in the medical profession. Professional satisfaction, increasing life expectancy, concerns regarding financial security, and reluctance to retire are among the many reasons a physician might choose to extend practice into later adulthood. Despite the benefits of experience and expertise acquired by older physicians, cognitive changes associated with normal or pathological aging have been shown to have a significant negative effect on physician performance. Age-based cognitive assessment of physicians has been adopted in some countries and by some U.S. healthcare institutions for patient protection and improvement of physician quality of life, but there is no general guideline for the assessment and assistance of cognitively impaired late career physicians in the United States. Self-reports and reports from peers are an inadequate safeguard, leaving impaired physicians and their patients at risk. In this discussion, we will describe cognitive aging, the effects of cognitive aging on physician performance, some current monitoring systems, and recommendations for identifying and assisting physicians found to be impaired., (Copyright © 2018 American Association for Geriatric Psychiatry.

Rema P, Mathew AP, Suchetha S, and Ahmed I
- Abstract
Cervical cancer usually presents in advanced stages and is treated with chemoradiation. About 15-20 % patients present with local recurrence after chemoradiation. Radical surgical resection is the only treatment modality offering long term survival benefit in recurrent cervical cancer. The most common surgical option for these patients is pelvic exenteration. Radical hysterectomy may be done for patients with a small centrally located recurrence in the cervix with no infiltration of adjacent structures. The aim of this study was to evaluate the morbidity and survival outcome following radical hysterectomy and pelvic exenteration for recurrent cancer cervix. We retrospectively reviewed the medical records of our patients who underwent surgery for cancer cervix recurrence from January 2010 to December 2014. The postoperative morbidity was considered early if it happened in the initial 30 days of surgery and late if it occurred after 30 days. All patients were followed up till February 2015. Survival analysis was done using Kaplan- Meir method. Between January 2010 and December 2014, 20 patients with recurrent cervical cancer underwent radical surgical resection. The median age of the study group was 43 years (range 28-63 years). Seventeen patients had squamous cell carcinoma and 3 had adenocarcinoma. 13 underwent pelvic exenteration and 7 patients underwent radical type 2 hysterectomy with bilateral pelvic lymphnode dissection. In the exenteration group, 8 patients had anterior exenteration, 4 had total exenteration and one had posterior exenteration. Urinary diversion was done by ileal conduit in 8 patients, double barrel colostomy in two and wet colostomy in two patients. There were no immediate postoperative deaths. Operating time, blood transfusions needed and hospital stay was more in the exenteration group compared to radical hysterectomy patients. After pelvic exenteration post-operative complications were seen in 76.9 % of which the most common was of the urinary tract including 3 patients with pyelonephritis, 5 had renal insufficiency and 2 patients developed urinary fistulae. Post-operative morbidity was lower in radical hysterectomy patients. There were two patients in the hysterectomy group who developed vault recurrence while none in the exenteration group had local recurrence. The median follow up time was 19 months (range 9-53 months).Three year overall survival for the entire cohort was 43 %. Median survival time for the exenteration group was 28 months which was significantly higher than 14 months for the radical hysterectomy group. This study shows that radical surgical resection is feasible with good survival outcome and acceptable morbidity in recurrent cancer cervix patients. Radical hysterectomy can be done in selected patients but pelvic exenteration has better long-term survival but with the potential for both short- & long-term complications.

- Abstract
Objective: The Accreditation Council of Graduate Medical Education (ACGME) Milestone Project is the next step in a series of changes revamping the system of graduate medical education. In 2013 the ACGME completed the general psychiatry milestones. The ACGME then pursued creation of milestones for accredited psychiatric subspecialty fellowships. This article documents the work of the geriatric psychiatry subspecialty milestones work group. It reports the history and rationale supporting the milestones, the milestone development process, and the implications for geriatric psychiatry fellowship training., Methods: In consultation with the American Association for Geriatric Psychiatry, the American Board of Psychiatry and Neurology, and the ACGME Psychiatry Residency Review Committee, the ACGME appointed a working group to create the geriatric psychiatry milestones using the general psychiatry milestones as a guide., Conclusion: The geriatric psychiatry milestones are the result of an iterative process resulting in the definition of the characteristics vital to a fellowship-trained geriatric psychiatrist. It is premature to assess their effect on psychiatric training. The true impact of the milestones will be determined as each training director uses the milestones to re-evaluate their program curriculum and the educational and clinical learning environment. The ACGME is currently collecting the information about the milestone performance of residents and fellows to further refine and determine how the milestones can best be used to assist programs in improving training., (Copyright © 2016 American Association for Geriatric Psychiatry.

Rema P and Ahmed I
- Abstract
There is a rising incidence of early cervical cancer in young patients as a result of screening and early detection. Treatment of cervical cancer by surgery or radiotherapy results in permanent infertility which affects the quality of life of cancer survivors. Now with improved survival rates among early cervical cancer patients, conservative surgery aiming at fertility preservation in those desiring future pregnancy is an accepted treatment. Conservative surgery is possible in early cervical cancer including micro invasive cancer and stage IB cancers less than 2 cm. Stage IA1 cervical cancer is treated effectively by cervical conisation. In stage IA2 cancers and stage IB1 cancers less than 2 cm the fertility preservation surgery is radical trachelectomy. Radical trachelectomy removes the cervix with medial parametrium and upper 2 cm vaginal cuff retaining the uterus and adnexa to allow future pregnancy. Radical trachelectomy is a safe procedure in selected patients with cancer cervix with acceptable oncologic risks and promising obstetric outcome. It should be avoided in tumours larger than 2 cm and aggressive histologic types. This article focuses on the current options of conservative surgery in early cervical cancer.

- Abstract
Context: Trismus is one of the common late side effects of radiotherapy (RT) of head and neck cancers. It occurs in about 30% of patients treated by telecobalt. It, in turn, leads to significant morbidity, including malnutrition, difficulty in speaking, and compromised oral hygiene with severe psychosocial, and economic impacts., Aims: To determine the prevalence of trismus and its progression in patients who have received radical concurrent chemoradiation for head and neck cancer by telecobalt at our institution. To note the effect of early rehabilitative measures on the severity of trismus and to assess its impact on the quality of life (QOL)., Subjects and Methods: A total of 47 evaluable patients of head and neck cancer patients treated by telecobalt with radical intent between January 2012 and December 2013 were analyzed and baseline maximal inter-incisal opening (MIO) and MIO at the completion of RT, after 3 months, 6 months, and 1 year, after completion of RT were noted. Grading of trismus was done using Modified Common Toxicity Criteria (CTCAE Version 3.0). QOL assessment was done using European Organization for Research and Treatment of Cancer QLQ-HN35. The time when the rehabilitative measures were started were also noted., Statistical Analysis Used: Chi-square test with Fisher exact probability test and Students t-test., Results: Radiation-induced trismus (RIT) was seen in 31.9%, 34.04%, and 38.39% of cases at 3, 6, and 12 months after completion of RT. Grade II and III trismus accounted for 17.02% and 6.38% at the end of 1 year. Patients who started regular rehabilitative exercises soon, after completion of RT had a better mean MIO as compared to those who were not compliant (32 mm vs. 24 mm at 1 year), and there was a trend toward delayed progression in them. Trismus was also seen to adversely affect QOL of the patients., Conclusions: RIT is a major cause for late morbidity in patients treated with conventional RT leading to poor QOL. Early rehabilitative measures are useful in preventing progression of trismus.

- Abstract
The aim of this study was to evaluate the morbidity and survival outcome following radical hysterectomy after chemoradiotherapy in the International Federation of Gynecology and Obstetrics (FIGO) stages IB-IIB cervical cancer patients in whom intracavitory brachytherapy was not feasible. We retrospectively reviewed the medical records of our patients who underwent adjuvant radical hysterectomy between January 2005 and December 2012. Post-operative complications were graded according to the grading system of Chassagne et al. (Radiother Oncol 26:195-202, 1993). Survival analysis was done using Kaplan-Meir method. Between January 2005 and December 2012, 43 patients underwent type 2 radical hysterectomy after external beam radiotherapy and concurrent chemotherapy. The median age of the study group was 44 years (range 28-63 years). There were no perioperative deaths. In the early post-operative period, there were 45 complications in 29 patients of which three were of grade 3 severity. The most common post operative complications were urinary tract infections and lymphoedema. The median follow-up time was 29 months (range 9-68 months). The 5-year overall survival was 85.5 % and disease-free survival 82.1 %. This study shows that radical hysterectomy is feasible with good survival outcome and acceptable morbidity after chemoradiotherapy in cervical cancer patients.

- Abstract
Background: There are various drugs tried for relieving pain associated with radiation-induced mucositis. This paper aims to study role of honey in relieving pain due to radiation induced mucositis in head and neck cancer patients receiving concomitant chemoradiation., Materials and Methods: A randomized controlled trial on 78 subjects (40 in test group and 38 in control group) was undertaken to study the analgesic effect of honey, but the analysis of 69 patients was done as nine patients (four in test and five in control group) were lost to follow-up or left treatment in between the study. All patients were advised to do salt-soda and benzydamine mouth gargles, alternatively every 3 hours. Test group patients additionally received 20 ml honey three times a day during the entire course of radiation treatment and 3 months following radiation therapy (RT)., Results: Honey significantly reduced the severity of mucositis associated pain and resulted in lesser treatment gaps and a decrease in overall radiotherapy treatment duration. None of the test group and majority of controls (51.5%) had severe pain score during the 7(th) week of RT. The same pattern was seen in the post-RT period. Mean pain score was significantly different in both groups during all weeks during and upto 6 weeks post-RT (mean score of 3.08 and 6.54 for test and control respectively at 7(th) week RT, P < 0.001)., Conclusion: Honey being a cheap, palatable, and natural medicament can be used for decreasing pain associated with radiation-induced mucositis in cancer patients.

- Abstract
Objective: To study if Asian ethnic groups in Hawaii today maintain folk-based beliefs about dementia, have inadequate biomedical understanding of dementia, and differ among each other regarding perceptions of dementia., Design: The study adapts and expands a 2004 survey of ethnic groups on perceptions of Alzheimer disease demonstrating that ethnic minority groups hold more folk perceptions and less biomedical perceptions of dementia than Caucasians. This study surveys particular ethnic minority family members of elders admitted to four long-term care and inpatient facilities in Hawaii. Seventy-one family members completed surveys, including 23 Chinese, 18 Filipino, and 30 Japanese participants. Elders may or may not have had the diagnosis of dementia, though an estimated half of elders in all four facilities already held the diagnosis of dementia., Results: Findings indicated that Japanese and Chinese respondents in this study held perceptions about dementia that were more consistent with current biomedical understanding compared with their Filipino counterparts (mean differences/percent correct for Japanese: 57%, Chinese: 56% versus Filipino: 38%; F = 6.39, df = 2,55, p = 0.003). Filipino respondents were less likely than Japanese and Chinese respondents to report that persons with dementia can develop physical and mental problems-97% of Japanese participants and 82% of Chinese participants responded correctly compared with 63% of Filipino participants (Fisher's Exact test p = 0.009). With regard to folk beliefs about dementia, variation occurred with no consistent trend among the groups., Conclusion: Low levels of biomedical understanding of dementia were reflected by all three subgroups of Asians living in Hawaii with less prominence of folk beliefs compared with prior studies of ethnic minority perceptions. Education did not predict variability in dementia perceptions among the groups. Lower levels of acculturation, suggested by primary home language other than English, may correlate with a perception of dementia that is less consistent with current biomedical understanding of dementia. Persisting folk beliefs about dementia and the evident lack of biomedical understanding, particularly the belief that dementia is a normal part of aging, emphasizes the need for more culturally tailored strategies in patient education about dementia and the importance of early intervention., (Copyright © 2015 American Association for Geriatric Psychiatry.

- Abstract
Purpose: To evaluate the safety and efficacy of a supraciliary micro-stent (CyPass Micro-Stent; Transcend Medical, Menlo Park, California, USA) for surgical treatment of glaucoma in patients refractory to topical medications., Design: Multicenter, single-arm interventional study., Methods: Patients with open-angle glaucoma (Shaffer Grade 3 and 4) and uncontrolled medicated intraocular pressure (IOP) >21 mm Hg at baseline and candidates for conventional glaucoma surgery were enrolled. Glaucoma medications were discontinued at surgery and resumed at investigator discretion. CyPass Micro-Stent implantation was completed in all patients using a standard clear corneal approach. Adverse events, postoperative IOP changes, and need for IOP-lowering medications during the first 12 postoperative months (12M) were monitored., Results: Sixty-five eyes were enrolled, and 55 were available at 12M, accounting for loss to follow-up and early termination. Baseline IOP was 24.5 ± 2.8 mm Hg, and the mean number of medications recorded was 2.2 ± 1.1. There were no serious intraoperative events or major adverse events (eg, retinal or choroidal detachment, persistent uveitis, persistent hyphema, hypotony maculopathy). The most common adverse events included IOP increases >30 mm Hg beyond 1 month (11%, 7/65), transient hyphema (6%, 4/65), and cataract progression (12%, 5/41 phakic eyes). Mean IOP was 16.4 ± 5.5 mm Hg at 12 months-a 34.7% reduction (P < .0001). Mean medication usage also decreased from baseline to a mean of 1.4 ± 1.3 medications at 12M (P = .002). In eyes originally indicated for conventional glaucoma surgery, no secondary surgery was performed in 83% (53/64)., Conclusion: Supraciliary stenting with the CyPass Micro-Stent effectively lowers IOP as a surgical treatment for glaucoma, precluding the need for more invasive glaucoma surgery in >80% of patients at 1 year, thereby reducing postoperative glaucoma surgical complications., (Copyright © 2015 Elsevier Inc.

- Abstract
Objective: Prevalence of hypertension was examined in a widely dispersed (45 110 km(2)) representative group of Ladakhi in Northern India. The influence of hypoxic environment of wide-ranged altitude (2600-4900 m) and lifestyle change on hypertension was studied., Methods: 2800 participants (age 20-94 years) were enrolled. Systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure of ≥90 mm Hg and/or taking current anti-hypertensive medicine was defined as hypertension. Height and weight for body mass index and SpO₂ were examined. The rural population comprised six subdivisions with a distinct altitude, dietary and occupational pattern. Participants in the urban area of Leh consist of two groups, that is, migrants settled in Leh from the Changthang nomadic area, and dwellers born in Leh. The prevalence of hypertension in the two groups was compared with that in the farmers and nomads in rural areas. The effects of ageing, hypoxia, dwelling at high altitude, obesity, modernised occupation, dwelling in an urban area, and rural-to-urban migration to hypertension were analysed by multiple logistic regression., Results: The prevalence of hypertension was 37.0% in all participants and highest in migrants settled in Leh (48.3%), followed by dwellers born in Leh town (41.1%) compared with those in rural areas (33.5). The prevalence of hypertension in nomads (all: 27.7%, Tibetan/Ladakhi: 19.7/31.9%)) living at higher altitude (4000-4900 m) was relatively low. The associated factors with hypertension were ageing, overweight, dwelling at higher altitude, engagement in modernised sedentary occupations, dwelling in urban areas, and rural-to-urban migration. The effects of lifestyle change and dwelling at high altitude were independently associated with hypertension by multivariate analysis adjusted with confounding factors., Conclusions: Socioeconomic and cultural factors play a big role with the effect of high altitude itself on high prevalence of hypertension in highlanders in Ladakh., (Published by the BMJ Publishing Group Limited.

- Abstract
Introduction: The main aim of this study was to determine the frequency of Enterobius vermicularis infections and other unique histopathological findings in patients diagnosed with acute appendicitis., Materials: This retrospective study was conducted in a tertiary care hospital of Karachi, Pakistan over a time period of 9 years from 2005 to 2013. The recorded demographic and histopathological data for the 2956 appendectomies performed during this time frame were extracted using a structured template form. Negative and incidental appendectomies were excluded from the study., Results: Out of the 2956 patients diagnosed with acute appendicitis, 84 (2.8%) patients had Enterobius vermicularis infections. Malignancy (n=2, 0.1%) and infection with Ascaris (n=1, 0.1%) was found very rarely among the patients.Eggs in lumen (n=22, 0.7%), mucinous cystadenoma (n=28, 1.0%), mucocele (n=11, 0.4%), lymphoma (n=9, 0.3%), obstruction in lumen (n=17, 0.6%) and purulent exudate (n=37, 1.3%) were also seldom seen in the histopathological reports., Conclusion: Enterobius vermicularis manifestation is a rare overall but a leading parasitic cause of appendicitis. Steps such as early diagnosis and regular de worming may help eradicate the need for surgeries.

- Abstract
Objective: To determine the use of information technology (IT) & electronic media for improving compliance rate to doctors' advice in hypertensive patients in Karachi., Methods: Total 400 persons (200 males & 200 females) were randomly selected in six districts of Karachi. Data was collected through a pretested questionnaire. Following was sample criteria: age above 15 years, living in Karachi and ambulatory. Persons admitted in a hospital, individuals who were doing some physical activity during survey e.g. exercise, labor work etc., individual in stressed condition, non-cooperative individuals - not willing to get BP checked and fill questionnaire, and pregnant women were excluded. Those who did not sign the consent form were also excluded. SPSS was used for data analysis and descriptive statistics was employed for sensitivity analysis., Results: For healthcare awareness, people look for health programs on radio and TV channels. Short Message Service (SMS) and phone are highly appreciated by patients for reminders. To increase compliance to doctors' advice, less educated people prefer phone calls over SMS whereas educated individuals favor SMS. Although price of medicine has not emerged as a major contributing factor for non-compliance, discount on medicinal products is highly appreciated by the patients., Conclusion: The study concludes that there is a widespread awareness of high blood pressure in the sample population of Karachi e.g. 72.5%. People consider reminder message system i.e. Calls and Short Messaging Service (SMS) would help them in improving compliance to doctors' advice.

- Abstract
Background: Distribution of Hepatitis C Virus (HCV) genotypes may be changed over time. Epidemiological Studies on distribution patterns of HCV genotypes in Pakistani population might assist for better treatment options and preventive strategies., Objectives: This study was conducted to determine distribution patterns of HCV genotypes in different geographical regions of Pakistan., Patients and Methods: In this cross-sectional study, 1818 randomly selected patients from different geographical regions of Pakistan, diagnosed with HCV infection by the third generation Enzyme Linked Immunosorbent Assay (ELISA), were included between April 2011 and December 2013. HCV RNA was detected in serum samples of patients by Reverse Transcription Polymerase Chain Reaction (RT- PCR) of the core region. Qualitative PCR was performed to determine viral load. HCV genotyping was performed by RT-nested PCR using type-specific primers of the core region. Frequency of different genotypes among patients was assessed according to gender, age and geographical region at the time of sampling., Results: Of 1818 HCV RNA positive samples, HCV genotypes PCR fragments were detected in 1552 (85.5%) samples. HCV genotype 3a was the predominant genotype (39.4%) followed by genotype 2a (24.93%). HCV genotype 3 was the predominant genotype in Punjab and Sindh regions, while genotype 2 was the most predominant genotype in Khyber Pakhtunkhwa region and the second predominant genotype after genotype 3 in Sindh region. The incidence of genotype 2a is increasing in our country with decrease in the incidence of genotype 3a. A higher incidence of HCV various genotypes were observed among male patients and those younger than 45 years., Conclusions: This study may facilitate treatment options and preventive strategies in Pakistan.

Rema P and Ahmed I
- Abstract
Fertility preservation is one of the major concerns of young patients diagnosed with gynecological cancer. With newer treatment regimens and better surgical techniques, survival rates after cancer treatment have improved, hence preservation of fertility has recently become an important issue in the treatment of gynecological cancers. Fertility sparing surgery may be an option for early-stage cervical cancer with the development of loop excision techniques and radical trachelectomy which allows a radical approach to cervix cancer at the same time preserving the uterus and thus fertility. Fertility preservation is possible in Stage 1 epithelial ovarian cancers, germ cell ovarian tumors, and borderline cancers. Hormonal therapy with progestin agents is effective in early endometrial cancer. In patients desiring future pregnancy, fertility sparing options must be explored before starting treatment for gynecologic cancers.

- Abstract
The major aim of surgeons has always been a minimalist approach towards surgery, thereby reducing the complications associated with the surgery. The gold standard treatment for cholelithiasis with cholecystitis is currently the four port laparoscopic cholecystectomy (4 PLC). Recently, a newer technique has been introduced which uses a single port, rather than the four ports, for the removal of the gall bladder laparoscopically; it is known as Single Incision Laparoscopic Cholecystectomy (SILC). This is a comparatively minimal approach towards surgery. Therefore the purpose of this review is to compare the advantages and the disadvantages of SILC versus 4PLC, and hence, to give an idea of whether SILC is ready to replace the traditional approach as the new treatment of choice.

- Abstract
Currently, natural products have been used in treating gouty arthritis and are recognized as xanthine oxidase inhibitors. Current study was designed to evaluate in vitro xanthine oxidase inhibitory potential of Gouticin and its ingredients extracts and in vivo hypouricemic activity of gouticin tablet 500 mg twice daily. Ethanol extracts of Gouticin and its ingredients were evaluated in vitro, at 200, 100, 50, 25 μ g/ml concentrations for xanthine oxidase inhibitory activity. IC(50) values of Gouticin and its ingredients were estimated. Further, in vivo therapeutic effect of Gouticin was investigated in comparison with allopathic medicine (Allopurinol) to treat gout. Total patients were 200 that were divided into test and control group. Herbal coded medicine (Gouticin) was given to test group and allopathic medicine allopurinol was administered to control group. In vitro, Gouticin has the highest percent inhibition at 96% followed by Allopurinol with 93% inhibition. In vivo study, mean serum uric acid level of patients was 4.62 mg/dl and 5.21mg/dl by use of Gouticin and Allopurinol at end of therapy. The study showed that herbal coded formulation gouticin and its ingredients are potential sources of natural xanthine oxidase inhibitors. Gouticin 500 mg twice daily is more effective than the allopurinol 300mg once daily in the management of gout.

- Abstract
Background: A test dose is used to detect intravascular injection during neuraxial block in pediatrics. Accidental intravascular epidural local anesthetic injection might be unrecognized in anesthetized children leading to potential life-threatening complications. In children, sevoflurane anesthesia blunts the hemodynamic response when intravascular cathecolamines are administered. No studies have explored the hemodynamics and the criteria for a positive test dose result following phenylephrine in sevoflurane anesthetized children., Methods: Healthy children undergoing minor procedures were randomly assigned to receive intravenous placebo, or 5 μg∙kg(-1) phenylephrine (n = 11/group) during sevoflurane anesthesia. Hemodynamic response was assessed using electrocardiography, pulse oxymetry and non-invasive blood pressure monitoring for 5 min following drug administration in anesthetized patients., Results: All patients receiving phenylephrine showed a decreased heart rate (HR) but not all of them met the positive criterion for test dose response. Overall, at 1 min, patients receiving phenylephrine showed a 25% decrease in HR from the baseline while an increase in blood pressure was noticed in 54% of patients receiving phenylephrine., Discussion: Phenylephrine might be a future indicator of positive intravascular test dose. Further investigation is needed to find out the phenylephrine dose that elicits a reliable hemodynamic response and whether phenylephrine needs to be dose age-adjusted in order to appreciate relevant hemodynamic changes in children receiving neuraxial blocks undergoing general anesthesia., (© 2013 Blackwell Publishing Ltd.)

- Abstract
Introduction: During magnetic resonance imaging (MRI), children are at risk for body temperature variations. The cold MRI environment that preserves the MRI magnet can cause serious hypothermia. On the other hand, hyperthermia may also develop because of radiofrequency-induced heating of the tissues, particularly in prolonged examinations. Because of a lack of MRI-compatible core temperature probes, temperature assessment is unreliable, and specific absorption rate-related patient heat gain must be calculated to determine the allowable scan duration. We compared an MRI-compatible temperature probe and a modification thereof to a standard esophageal core body temperature probe in children., Methods: Children undergoing general anesthesia were recruited, each patient serving as his/her own control. Core body temperature was measured using 3 different devices: (1) a fiberoptic MRI-compatible skin surface temperature probe (MRI-skin) located on the child's skin surface; (2) a fiberoptic MRI-compatible temperature probe modified with a single-use sleeve at the tip (MRI-core), located in the nasopharynx; and (3) a standard temperature monitor (STRD) located in the esophagus or nasopharynx. The Bland-Altman method was used for statistical analysis., Results: We enrolled 60 children aged 7.8 ± 6 years (mean ± SD) weighing 32.4 (±26.4) kg. The estimated difference between the STRD and MRI-core measurements of core temperature was 0.06°C (confidence interval [CI]: -0.02, 0.15), and between the STRD and the MRI-skin 1.19°C (CI: 0.97, 1.41). According to the Bland-Altman analysis, the 95% limits of agreement ranged from -0.9 to 3.4 and from -1.3 to 1.2 between the STRD and the MRI-skin probe and the MRI-core probe, respectively., Discussion: Our results show good agreement between standard esophageal measurements of core temperature and core temperature measured using a modified MRI-core probe during general anesthesia in a general surgical pediatric population. The ability to accurately assess core temperature in the MRI suite may safely allow longer scan times and therefore reduce repeat anesthetic exposure, improve patient safety, and enhance the quality of care in children.
