Purpose: The purpose of this study was to evaluate retrospectively the efficacy and safety profile of intravitreal injection of bevacizumab bio?similar product Zybev(Z) for macular edema because of retinal diseases. Methods: A retrospective analysis was conducted on patients with macular edema because of retinal diseases, who had been administered intravitreal injections of bio?similar bevacizumab at a tertiary eye care center. Changes in the retinal thickness and visual acuity were evaluated to judge the efficacy, and adverse events were noted for the safety profile over a period of 6 weeks. Results: A total of 104 patients were included in the study. The mean age of the patients was 53 ± 13.5 years. The mean pre?injection best corrected visual acuity (BCVA) was 1.32 ± 0.70 log minimum angle of resolution (logMAR) with a central subfield thickness (CST) of 429.26 ± 204.30 ?m, and the post?injection BCVA at 6 weeks was 1.13 ± 0.71 logMAR with a CST of 302.26 ± 104.50 ?m; this change was statistically significant (P < 0.05) for all groups. The mean average cube thickness (?m) decreased from 11.85 ± 1.96 pre?injection to 10.52 ± 1.75 post?injection, and the mean average cube volume (mm3) decreased from 329.30 ± 54.35 to 302.23 ± 49.56 (P < 0.05). During the follow?up period after injection, no patient had inflammation, endophthalmitis, an increase in intra?ocular pressure, or systemic side effects. Conclusion: This short?term retrospective analysis provides evidence regarding the efficacy and safety of intravitreal injection of bio?similar products of bevacizumab for the treatment of macular edema because of retinal diseases

Argon Beam Coagulation as an Adjuvant for Extended Curettage for Giant Cell Tumors of the Bone: A Study of 50 Cases / Coagulação por plasma de argônio como adjuvante à curetagem estendida em tumores de células gigantes do osso: Um estudo de 50 casos

Abstract Objective Extended curettage with adjuvants of giant cell tumors of bone is associated with a lower rate of recurrence of the tumor while preserving the adjacent joint. The present study was conducted to estimate the recurrence rate and functional outcome after using argon beam as an adjuvant for extended curettage. Methods We selected 50 patients with giant cell tumors, meeting all the inclusion criteria, who underwent extended curettage using high speed burr and argon beam photocoagulation between July 2016 to January 2019. On their follow-up visit, they were assessed for any complaints of pain and signs like tenderness, locally raised temperature, and decreased range of motion of the adjacent joint. Radiologically, the patients were assessed for any increased lucency around the cement mantle and uptake of the subarticular graft. Musculoskeletal Tumor Society Score (MSTS) was administered to the patients, and range of motion of the adjacent joint was compared with the contralateral joint. Results Recurrence was found in 4 patients, that is, an 8% recurrence rate. Twenty-six out of 28 patients with a tumor in the lower limb had a grade-5 weight bearing status 6 months from the surgery, and their range of motion was comparable to contralateral healthy joint with an average MSTS score of 27 (18-30). Conclusion Extended curettage of giant cell tumors using argon beam coagulation is associated with low recurrence rates of the tumor and is an effective modality in the treatment of these tumors besides having a functional outcome comparable to the healthy limb.

Resumo Objetivo A curetagem estendida com adjuvantes de tumores de células gigantes do osso está associada a uma menor taxa de recidiva da neoplasia e à preservação da articulação adjacente. Este estudo foi feito para estimar a taxa de recidiva e o resultado funcional após o uso de plasma de argônio como adjuvante à curetagem estendida. Métodos Cinquenta pacientes com tumores de células gigantes que atendiam a todos os critérios de inclusão foram selecionados para o estudo e submetidos à curetagem estendida com broca de alta velocidade e fotocoagulação com plasma de argônio entre julho de 2016 e janeiro de 2019. À consulta de acompanhamento, os pacientes foram avaliados quanto a quaisquer queixas de dor e sinais como sensibilidade, aumento local da temperatura e diminuição da amplitude de movimento da articulação adjacente. Radiologicamente, os pacientes foram avaliados quanto à presença de qualquer aumento de radiotransparência ao redor do manto de cimento e incorporação do enxerto subarticular. O questionário Musculoskeletal Tumor Society Score (MSTS) foi administrado aos pacientes e a amplitude de movimentação da articulação adjacente foi comparada à articulação contralateral. Resultados Quatro pacientes apresentaram recidiva, o que corresponde a uma taxa de 8%. Seis meses após a cirurgia, 26 de 28 pacientes com tumor no membro inferior tinham capacidade de sustentação de peso de grau 5 e amplitude de movimento comparável à articulação saudável contralateral, com pontuação MSTS média de 27 (intervalo de 18 a 30). Conclusão A curetagem estendida de tumores de células gigantes com coagulação por plasma de argônio está associada a baixas taxas de recidiva da neoplasia; é uma modalidade eficaz no tratamento desses tumores e o resultado funcional é comparável ao do membro saudável.

Binocular summation in comitant exotropia: Change after surgery

Purpose: To assess the change in binocular summation (BiS) in comitant exotropia (XT) after strabismus surgery. Methods: This is a prospective study on 20 patients who underwent surgery for comitant XT over a one year period. Patients with sensory exotropia and nystagmus were excluded. Best?corrected visual acuity (VA) and contrast sensitivity (CS) of both eyes separately and together (binocularly) were recorded. BiS score was calculated as binocular score minus better eye score. BiS score at the end of 3 months was compared with the preoperative data. Results: The mean ± SD of BiS score increased from 2.95 ± 0.88 to 4.55 ± 0.68 (P?value < 0.0001) for VA (on ETDRS letters) and from 2.75 ± 0.44 to 4.5 ± 0.76 (P?value < 0.001 for CS (on Pelli–Robson chart) after surgery. Conclusion: There is significant improvement in BiS in XT after strabismus surgery. Authors recommend its inclusion in evaluation of functional outcome of XT surgery

Effect of prenap coffee on daytime sleepiness in university students

Background: Daytime sleepiness impairs academic performance in college students. Napping is a counter to daytime sleepiness, but often causes sleep inertia on waking up. Caffeine absorption from beverages peaks 30 minutes after their ingestion presenting a window of opportunity to have a short nap such that the time of waking up is in synchrony with onset of action of caffeine; thereby abolishing post-nap inertia and achieving synergistic mitigation of fatigue.Objective of this study to assess effect of nap, coffee, ‘coffee and nap’ and ‘wakeful break without coffee’ on daytime sleepiness using Psychomotor Vigilance Tests (PVTs) and Karolinska Sleepiness Scale (KSS) score.Methods: After Institutional Review Board clearance, 10 subjects (aged 19-21 years) were selected using their Epworth Sleepiness Scale score (ESS >5) and called to the study site 8 times on different days to be exposed to these four conditions twice - only coffee (standardized), only nap (30min), coffee immediately followed by 30min nap, wakeful break (30min) without coffee or nap. Pre and post scores were recorded for electronic PVT (Reaction Time and Motor Responsiveness) and KSS for each attempt.Results: Test outcome was associated with intervention used (p=0.00001). ‘Nap only’ group was associated with deterioration in outcomes (p=0.00001), accounting for highest percentage (41%) of all deteriorated test outcomes. ‘Coffee only’ group was associated with improvement in test scores (p=0.00001), responsible for highest share (38.8%) of all improved test outcomes. ‘Nap only’ and ‘Coffee-nap’ group showed improvement in 11.67% and 21.67% of outcomes respectively. Conclusions: Pre-nap coffee is a proactive counter-measure to post nap sleep inertia.

Role of hysterolaparoscopy in the diagnosis and management of infertility

Background: Infertility is defined by WHO and ICMART as a disease of the reproductive system by the failure to achieve a clinical pregnancy after 12 months or more regular unprotected sexual intercourse. Objective of this study were to assess the role of hysteroscopy and laparoscopy in the evaluation of female infertility. To assess the therapeutic role of these endoscopic modalities in cases of infertility.Methods: A prospective study of 112 women coming with the complain of infertility to a tertiary care centre hospital in Ahmedabad over a period of 30 months from January 2017 to June 2019.Results: Of the 112 cases, 69.7% had primary infertility and 30.3% had secondary infertility. Septum was the most common hysteroscopic finding (7.1%) followed by polyps (5.4%) and synechiae (3.6%). Adhesions was the most common laparoscopic finding (23.2%) followed by tubal blocks (19.7%) and fibroid (17.9%). Polycystic ovaries were seen in 12.5% patients followed by endometriosis in 10.7% women. Myomectomy was most common therapeutic procedure (17.9%) followed by adhesiolysis in 14.3% women and PCO drilling in 8.9% women.Conclusions: Hysterolaparoscopy is useful as a diagnostic and therapeutic measure for women having infertility.

Evaluation of prescription pattern and quality of life in postmenopausal osteoporosis: a cross sectional study

Background: Osteoporosis (OP) is a silently progressing metabolic bone disease that results in loss of mineralized bone and subsequent fractures with minor trauma. Fracture related pain and physical inability to perform activities of daily living can lead to psychological consequences that impair Quality of Life (QoF). However, much less is known about Indian scenario. Hence, our study becomes imperative. Aim of this study to the drug utilization pattern and to analyze Quality of life of postmenopausal women suffering from osteoporosis.Methods: An analytical cross-sectional study was done on 91 post-menopausal osteoporotic women. Drug utilization pattern was evaluated. Pre-validated QUALEFFO-31 questionnaire was administered to each patient to record patient’s perceived QoL. Scores were calculated according to the algorithm. Higher scores indicated poor QoL. The collected data was analyzed with SPSS software (version 23)and p value ?0.05 was considered as statistically significant.Results: The mean age group of presenting patients was 56.2±6.6 years. All the patients received Calcium and vitamin D supplements and non-steroidal anti-inflammatory drugs for pain relief. But only 33% of the patients received any one of the bisphosphonates (BP). For analysis, patients were grouped into Group-1(n=60) who did not and Group-2 (n=31) who did receive a BP. QOL analysis showed that pain domain was affected the most. Also, patients in Group 2 reported worse score in all the domains in comparison to Group 1 (P<0.05). It is likely that BP might need more time to show considerable effect or because it was added only to those patients who already had more complaints and could afford the high cost.Conclusion: BP in spite of being the drug of choice for OP is used less commonly in India. OP causes pain and physical debilitation with detrimental effect on mental health. Longer duration prospective studies are needed to study the association of QoL and use of BP in OP patients.

Transscleral fixation of closed loop haptic acrylic posterior chamber intraocular lens in aphakic nonvitrectomized eyes.

Purpose: To evaluate the outcome of transscleral fixation of closed loop haptic acrylic posterior chamber intraocular lens (PCIOL) in aphakia in nonvitrectomized eyes. Materials and Methods: Patients with postcataract surgery aphakia, trauma with posterior capsule injury, subluxated crystalline lens, and per operative complications where sulcus implantation was not possible were included over a 1‑year period. Scleral fixation of acrylic hydrophilic PCIOL was performed according to the described technique, and the patients were evaluated on the day 1, 3, 14, and at 3 and 12 months postoperatively for IOL centration, pseudophakodonesis, change in best‑corrected visual acuity (BCVA), and any other complications. Results: Out of twenty‑nine eyes of 24 patients, who completed the study, 25 (86.2%) eyes had improved, 2 (6.9%) eyes showed no change, and 2 (6.9%) eyes had worsening of BCVA. Three (10.3%) eyes developed postoperative complications. A significant improvement in mean BCVA (P < 0.0001) was observed after the procedure. Mean duration of follow‑up was 26.2 months (range 22–35 months). Conclusion: The use of closed loop haptic acrylic IOL for scleral fixation appears to be safe and effective alternative to conventional scleral fixated polymethyl methacrylate intraocular lenses.

Adjustable recessions in horizontal comitant strabismus: A pilot study.

Aim: To compare the surgical outcome of adjustable with the conventional recession in patients with horizontal comitant strabismus. Patients and Methods: A prospective comparative nonrandomized interventional pilot study was performed on patients with horizontal comitant strabismus. Fifty‑four patients (27 in each group) were allocated into 2 groups to undergo either adjustable suture (AS) recession or non‑AS (NAS) recession along with conventional resection. The patients were followed up for 6 months. A successful outcome was defined as deviation ±10 prism diopters at 6 months. The results were statistically analyzed by Chi‑square test, Fisher’s exact test, and Student’s t‑test. Results: A successful outcome was found in 24 (88.8%) patients in AS and 17 (62.9%) in NAS group (P = 0.02). The postoperative adjustment was done in 13 (48.1%) patients in AS group. There was one complication (tenon’s cyst) in AS group. Conclusion: AS recession may be considered in all cooperative patients undergoing strabismus surgery for comitant deviations.

A novel technique to recanalize the nasolacrimal duct with endodiathermy bipolar probe.

Aims: To evaluate a new approach for recanalization (RC) of nasolacrimal duct obstruction in the treatment of the symptomatic nasolacrimal duct obstruction (NLDO). Materials and Methods: A prospective, interventional, comparative study in 302 eyes of 209 patients of symptomatic nontraumatic NLDO. Eyes with previous failed surgery were excluded. One hundred and fifty‑one eyes underwent RC with 20 G endodiathermy bipolar probe connected to a 7 W diathermy followed by bicanalicular intubation under direct visualization. One hundred and fifty‑one eyes underwent standard external dacryocystorhinostomy (DCR). Follow‑up was for 24 months and evaluation was done on basis of change in symptoms and lacrimal syringing. Data was analyzed by Chi‑square test and unpaired t‑test. P value < 0.05 was considered statistically significant. Results: Success defined as an asymptomatic patient or freely patent syringing was 92.7% (140 eyes) in RC group and 83.44% (126 eyes) in DCR group. Success was significantly more (P ≤ 0.01) in RC than DCR group. Surgical time was significantly less in RC than DCR (P ≤ 0.001). In RC group, RC could not be performed in three eyes and had to be later taken up for DCR. Intubation after RC was not achieved in four eyes; however these eyes had a patent pathway till 24 months. Twenty‑two eyes had a premature extrusion of the tube; but the success rate in these (20 eyes) was comparable to the others within the group (P > 0.05). Two eyes in RC and one in DCR group had complications. Conclusions: RC with 20 G endodiathermy bipolar probe is a quick, simple, and effective alternative to standard external DCR.
