Chondrosarcoma of the anterior chest wall: surgical resection and reconstruction, our institutional experience
Authors: Shanmugam Subbiah , C. H. Radha Siva Bharath 
Published: June 2023

Primary chest wall tumours are not very common. Chondrosarcomas is most common tumour arising from the chest wall. It occurs more often during the third and fourth decade of life. Chondrosarcomas are resistant to conventional chemotherapy and radiotherapy. Wide margin surgical excision remains the best available treatment approach. For chondrosarcomas involving the chest wall, surgical excision may result in chest wall defects that may require reconstruction to obliterate dead space, restore chest wall rigidity, preserve respiratory mechanics, maintain pulmonary function, protect intrathoracic organs, provide soft tissue coverage and minimize deformity. In this article we present a series of 3 cases of chondrosarcoma of anterior chest wall managed at government Royapettah hospital, Kilpauk medical college, Chennai. A 71-year-old male patient, a case of 22×20 cm giant chondrosarcoma arising from anterior left chest wall involving 2nd to 8th ribs. We did wide local excision and reconstruction of chest wall with a synthetic bone cement (methyl methacrylate) construct, sandwiched between two layers of polypropylene mesh. A 38-year-old male patient, a case of 8×6 cm chondrosarcoma of left anterior chest wall involving 9th rib, we did wide excision of tumor along with 8th, 9th, 10th ribs and defect reconstructed with prolene mesh. A 37-year-old male patient, a case of 5×4 cm chondrosarcoma arising from left 4th rib. We did wide excision along with 4th rib and primary closure. Patients with chondrosarcomas generally have a good prognosis when optimally diagnosed and treated. Our case series is interesting due to the different sizes of chondrosarcomas at presentation, which are managed differently. Complete resection with wide surgical margin remains the best available treatment, but post resection chest wall reconstruction is posing a great surgical challenge.

Diabetic retinopathy is the most common vision-threatening chronic microvascular, microangiopathy complication of diabetes militias.We have designed this cross sectional observational study to understand the role of serum lipids and random plasma glucose level with severity of diabetic retinopathy (DR). This study was accomplished with 210 patients that came to us in the diabetic clinic. There were two groups: Group A - All DM patients with no apparent sign of diabetic retinopathy (Grade I) and Group B - All DM Patients with any signs of diabetic retinopathy (Grade II - V). Diabetic retinopathy (DR) was graded according to The International Clinical Diabetic Retinopathy Disease Severity Scale on dilated fundus examination and fundus phtotograpgy. Serum lipids (Total, LDL, and HDL cholesterol and triglycerides) were then assessed according to NCEP ATP III guidlines. The correlation of the severity DR was then assessed with serum lipids and random plasm glucose.We found that total cholesterol and triglycerides played a detrimental role in the severity of diabetic retinopathy and the likelihood of developing a more severe form of diabetic retinopathy was dependent on their levels (P&#60;0.05). The Association of HDL and LDL with different grades of diabetic retinopathy was also found significant (P&#60;0.05). However, the association of VLDL (P&#62;0.05) was found insignificant. Similarly, the values of total cholesterol, triglycerides and HDL showed a significant rise with severity of diabetic macular edema (DME)In this present study, the significant association of total cholesterol, triglycerides and HDL with DR thus concludes that along with strict glycemic monitoring and control, the of control of hyperlipidemia is also noteworthy to prevent the progression of DR and DME.

Antibiotic sensitivity pattern of bacterial isolates varies from place to place and time to time. This study is aimed at determining the sensitivity patterns in our setup. In the era of emerging resistance to antibiotics, there is a need to determine the antibiotic sensitivity pattern of bacterial isolates from ocular infections and to compare the antibiotic sensitivity pattern of bacterial isolates in ocular infections among patients with and without diabetes mellitus. 1. To determine the antibiotic sensitivity pattern of bacterial isolates in ocular infections. 2. To compare the antibiotic sensitivity pattern of bacterial isolates from ocular infections among patients with and without diabetes mellitus. 3. To study the predisposing factors for development of the multidrug resistant bacteria in ocular infections.: It was a hospital based cross-sectional study carried out among the patients presenting to Outpatient department of Hassan Institute of Medical Sciences, Hassan, Karnataka from January 2022 to June 2022. The aims and objectives of the intended study were explained to the subjects and informed written consent was taken. Institutional ethical clearance was obtained. Data was collected as per the proforma sheet. 110 samples were divided into two groups- Diabetics (Group A) & Non diabetics (Group B). Majority70(63.6%) of samples sent were from ocular pathology Chronic dacryocystitis. Positivity rate of cultures was 31.8%. Most common isolate in both groups was Staphylococcus aureus. 89% of positive culture patients had history of antibiotic abuse. Highest sensitivity was seen with aminoglycosides and resistance was seen with macrolide like azithromycin and fluroquinolone like ciprofloxacin. Antibiotic sensitivity and resistance patterns of bacterial isolates in ocular infections was similar in both Diabetics (Group A) and Non diabetics (Group B). Highest sensitivity was seen for Amikacin, Gentamicin and Tobramycin in both groups. Highest resistance was seen for Azithromycin, Amoxicillin clavulanic acid, Ciprofloxacin in both groups.Multidrug resistance was due to previous history of use of antibiotics, injudicious use of antibiotics for viral, allergic and other conditions, incomplete treatment for ocular infections and extended duration of antibiotic usage.

Diabetes Mellitus (DM) is a significant public health burden in India. Focus on Diabetes and its complications is important to prevent mortality and morbidity due to this disease. Lack of awareness is one of the main barrier for detection of DM and its complications. Diabetic retinopathy (DR) is one of the most common complication of DM which causes of blindness and visual impairment. The purpose of this study was to assess knowledge and attitude of diabetic patients towards eye care and DR in urban south Indian population.Cross-sectional study was done on 537 patients with Type 2 Diabetes Mellitus. All patients underwent complete ocular examination including visual acuity, anterior segment and fundus examination using slit-lamp biomicroscope by attending Ophthalmologist. They were administered questionnaire to test their knowledge and attitude. Their answers were documented. Statistical analysis was done using SPSS software (IBM).Out of 537 patients (50.9%) patients knew that there was relationship between Diabetes and Retinopathy while (49.1%) patients were not aware of. 60.4% of patients were of the opinion that there was no need of regular screening if vision in both eyes are good and 39.6% of patients were of the opinion that they should undergo a routine ophthalmology screening every year despite of good vision in both the eyes. 69.6% of patients said that good control of DM might prevent DR. The level of knowledge of DR was found to be significantly associated with patients’ educational level (p=0.038). Patients with relatively higher educational level were more aware of DR occurring as a consequence of diabetes. Patients with longer duration of Diabetes had more knowledge on DR (p=0.001).In our study there was an association between educational qualification and knowledge regarding Diabetic retinopathy. (p value=0.04). This stresses on the importance of health education amongst rural and illiterate population.

To compare results of early intra-operative versus post-operative Descemet’s membrane detachment (DMD) detection and descemetopexy.Data was collected retrospectively for patients who developed DMD from December 2018 to March 2020 and underwent air descemetopexy.: The study comprised of 85 eyes of 85 patients. (which 4 were excluded.) There were 41 males and 39 females. Mean age was 66.93 years (SD ± 12.21). 4 eyes had mild DMD which were excluded from final analysis. 55 eyes had moderate & 26 had severe DMD. 68 eyes had intraoperative descemetopexy (Group 1) and 13 had late detection of DMD with late post-operative descemetopexy (Group 2). Median final BCVA in group 1 was 0.17 logMAR(IQR 0.13) & in group 2 was 0.60 logMAR(IQR 0.22).Air descemetopexy gives acceptable results in cases of DMD. However early detection of DM detachment during primary surgery with early descemetopexy yields better results in visual outcome of patients. Hence, carefulness in detection of intra-operative complications should be kept and early descemetopexy should be considered to prevent severe visual loss due to DMD.

To compare surgically induced astigmatism after manual small incision cataract surgery and phacoemulsification surgery. 2) To know the prevalence of pre-existing astigmatism, it’s magnitude and type and patients with cataract. 3) To calculate the average astigmatism induced after manual small incision cataract surgery and also to know the type of astigmatism and change in it in first month of surgery. 4) To calculate the average astigmatism induced after phacoemulsification surgery and also to know the type of astigmatism and change in its first month of surgery. 5) To study changes in astigmatism and its effect on vision after cataract surgery. 6) To compare astigmatism induced by straight and frown incision after operation.The study was carried out in Department of Ophthalmology, P.D.U government Medical College, Rajkot under guidance of operating surgeons and patients operated in the duration of 24 months from September 2020 to October 2022.Informed consent was obtained from all the patients undergoing study. It was a prospective study and all the patients were randomly selected over the above mentioned period that had cataract with normal anterior and posterior segments. To have a more homogeneous study population all the patients underwent a similar Preoperative, Intra operative, Postoperative Surgical protocols. All eyes were operated under peribulbar anaesthesia with 2% lignocaine+bupivacain+hyalronidase. Superior sclero corneal pocket tunnel with external incision of frown configuration in manual SICS and straight incision in phacoemulsification was made. All the cases with 3.2 mm of incision in phacoemulsification and 6.5 mm incision in manual SICS were taken. Surgically induced astigmatism was then calculated by the subtraction method and vector analysis.Average SIA in SICS was 1.32 SD and in Phacoemulsification was 0.60 SD which means that larger incision size increases SIA. SIA was maximum on first post-operative day and it regressed with time as noted on first post-operative month in both the groups. It decreased from 1.66 D on first postoperative day to 1.32 D on first postoperative month in SICS Patients and from 0.63 D to 0.60 D in Phacoemulsification patient.

: Pre-eclampsia is a severe life threatening complications of pregnancy and it is characterized by hypertension and significant amount of protein in urine usually occurring during the second half of pregnancy which is mostly after 20 weeks of pregnancy. A systemic meta analysis was planned to analyze and study the recorded pre-eclampsia cases and their fundus changes associated during pregnancy. This systemic self-study have reviewed the facts which were published earlier to determine the current scenario by vast study of statistics and derivation of facts. Vast meta-analysis were conducted with proper examination of data were made to evaluate with final conclusion.Based on our meta-analysis & systematic evaluation on pre-eclampsia and ocular fundus manifestation during pregnancy we observed, studied and derived into several facts and results. We also inferred that ocular examination in patients with pregnancy induced hypertension should be considered as an important tool of clinical evaluation to asses, predict and diagnose the safety of fetal outcomes and the complication and future risk of mother’s life.We conclude that well-being of both mother and fetus is very crucial during pregnancy. This well-being mostly depends upon the placental circulation. Ophthalmic examination of mother’s fundus could be very important tool to assess the health and well-being of both mother and fetus which might indicate to similar microcirculatory changes in placenta and indirectly to fetal well-being.

Published: June 2023

To evaluate the prevalence, topographical location and histological type of recurrent basal cell carcinoma in periocular region at tertiary care centre. Clinical and histological data was collected from the patients treated for recurrent basal cell carcinoma (BCC) in periocular region during Jan 2019 to Dec 2021 was analyzed for prevalence, topography, histological type in recurrent cases.280 cases were managed during Jan 2019 to Dec 2021. Out of these 44 were recurrent BCC. In recurrent cases 30 were male and 14 were female. Majority of recurrences about 80% occurred within 3 years of primary excision. Ocular adenexa is most common anatomical site for recurrent basal cell carcinoma. Histologically also more than 80% cases were having of recurrence. Recurrence after incomplete excision is reported to be 20% with 5-9 years of follow-up. Thus, we suggest that all patients who had undergone BCC surgical excision should be re-examined regularly even if surgical margins were negative on histopathology or tumor was indolent in nature.

Published: June 2023

: Diabetic retinopathy (DR) is a consequence of diabetes in patients and causes impairment in vision. Despite advances in science the treatment of DR is challenging. This paper presents a case of diabetic retinopathy treated successfully using Yoga Prana Vidya healing protocols.: Case study method is used in this study going through patient medical records, YPV healer’s records and patient feedback.: Within 8 weeks of YPV healing intervention, blurriness in vision fully reduced, normal vision restored, and the patient could work longer on computer without feeling strain. Eye drop usage reduced upon medical advice to just once or twice daily. Also, the patient’s diabetes condition was very stable and under control, and stress levels reduced greatly as a result of sustained YPV practices. A follow up after 10 months revealed that the patient was able to sustain the changes, stable and happy.: The integrated and holistic system of Yoga Prana Vidya Protocols have enabled the diabetic retinopathy patient to regain normal vision and stable controlled diabetes with lower stress levels. Further research with appropriate methodology and sample is recommended. It will be helpful for frontline health workers to learn and practice YPV protocols to complement their specialties for holistic treatment of patients.

Published: June 2023

Este estudo apresenta a utilização do aparelho celular como recurso didático-pedagógico na escola. Tem como cenário o contexto da pandemia do coronavírus da COVID-19, ano de 2021, onde professores se desafiaram em aulas online, via aplicativos de mensagens instantâneas, com destaque para o uso do WhatsApp. A partir da utilização do aplicativo, desenvolveram-se práticas pedagógicas com a finalidade de reestabelecer a relação professor-aluno, impossibilitada pelo isolamento social e o fechamento das escolas. Esta pesquisa, de abordagem qualitativa, desenvolvida nesse período, teve por objetivo, investigar como ocorreu a mediação pedagógica nas aulas online desenvolvidas pelo aplicativo WhatsApp. O estudo desenvolveu-se em uma turma do 1º Ano do Ensino Fundamental, de uma escola da rede municipal de Santana, no estado do Amapá. Adotou-se para coleta de informações, junto à professora, a entrevista semiestruturada e a observação sistematizada das aulas remotas, nos meses de agosto e setembro de 2021, via grupo da turma do WhatsApp. Com os alunos, realizou-se uma Roda de Conversa. Nos resultados, constatou-se que o aluno necessita de um acompanhante familiar nas aulas remotas, de forma a auxiliá-lo nas atividades propostas pela professora, visto que, sem isso, os objetivos educacionais ficam comprometidos; além disso, a mediação pedagógica mostrou-se insatisfatória nas práticas docentes no 1º Ano do Ensino Fundamental, dada as condições diversas tanto do professor como dos alunos. Entretanto, conclui-se que há possibilidades para a utilização do WhatsApp no 1º Ano do Ensino Fundamental para favorecer o desenvolvimento de novas estratégias de ensino, contribuindo para o ensino e a expansão da sala de aula.

Authors: Gava Gustavo Luiz , Haviaras Mariana 
Published: June 2023

esta pesquisa, buscou-se discutir uma necessidade pedagógica que vem se destacando celeremente nos últimos anos e, principalmente, devido ao fenômeno da pandemia causado pelo coronavírus: a urgência de Ambientes Virtuais de Aprendizagem (AVA) capazes de potencializar a sensação de pertencimento nos estudantes. A fundamentação metodológica dessa pesquisa foi subdividida em três momentos e por meio de natureza triangular: bibliográfica, qualitativa e exploratória-retrodutiva, ou seja, a de responder uma hipótese com fins de aplicabilidade: como seria possível a relação afetiva por meio de um ambiente virtual que busca promover a aprendizagem? O resultado alcançado nesse levantamento demonstrou que existem alguns fatores que devem ser considerados na relação afetiva e o sentimento de pertencimento entre os estudantes quando experienciam um Objeto Digital de Aprendizagem (ODA). Para isso, os critérios considerados para o desenvolvimento desse objeto foram: a qualidade de acesso à Internet, a arquitetura pedagógica do ambiente virtual e a experiência neurocognitiva com os objetos digitais. Diante dessa questão, o objetivo final dessa pesquisa foi idear um ODA, tendo como mote as dores dos estudantes de uma Instituição de Ensino Superior (IES). O intuito foi o de apresentar uma proposta de ODA pensado de forma situacional, a fim de potencializar o uso do próprio AVA, e de instigar o sentimento de pertencimento a um lugar (virtual) entre docente e discente, ou seja, a relação afetiva mesmo em ciberespaço. Por fim, apresentou-se um protótipo de ODA denominado “Conecta Mais”, a fim de estimular a aprendizagem coparticipativa entre estudantes, docentes e comunidade. Esse objeto se encontra em fase piloto de aplicação em uma Instituição de Ensino Superior do Estado do Paraná.
