MEDICAL NEGLIGENCE AND THE RES IPSA LOQUITUR DOCTRINE IN THE ADMINISTRATION OF CANCER TREATMENT IN SOUTH AFRICA
Authors: CA Maimela
Published: March 2022

Medical negligence is one of the leading socio-economic challenges faced by the health sector in South Africa and across the globe. This is attributed to the fact that millions of Rands are paid out by private and public hospitals to victims of medical malpractice on a daily basis, with dire consequences. For example, health establishments, particularly in the public sector, are unable to realise their duty to provide health care to millions of disadvantaged people as enshrined by section 27(1) of the Constitution as funds meant to provide health care go instead towards the payment of medical malpractice claims. Furthermore, medical practitioners in private and public hospitals now practise defensive medicine in order to avoid being sued for medical malpractice and this results in compromised health care for patients. This contribution aims to prove that people living with cancer can be exposed to medical malpractice just like patients who suffer from any other chronic medical condition, and also to dispel the myths connected to cancer treatment and care from a medical and a social perspective. In addition to the above, the contribution exposes the importance of the res ipsa loquitur doctrine (the thing speaks for itself) in solving complex medical negligence cases, with the aim of ensuring that justice is served to all patients living with cancer or other health impairments.

Authors: ÖZDEMİR Atilla , ÇEKİRDEKCİ Sıtkı
Published: March 2022

The primary purpose of this study is to determine the geometric habits of mind of classroom teacher candidates and the level of these habits. The study was conducted with 55 elementary education program students studying at an education faculty in the 2017-2018 spring term. The criterion used in the determination of the study group is that the teacher candidates should have knowledge about almost all the courses in the classroom education program and have taken courses I and II in mathematics teaching. Three worksheets were distributed to the teacher candidates as a data collection tool. Since the research is like a case study, the mathematical ideas developed by the teacher candidates about quadrilaterals and their written answers were summarized and interpreted according to the predetermined themes. When the findings obtained as a result of the research are examined in general, it can be said that teacher candidates are not sufficient in finding relationships between quadrilaterals, generalizing the relationships they find by using strategies, associating the feature valid for a quadrilateral with quadrilaterals that may have that feature, namely the whole, and making judgments.

The study purpose was to determine the effect of a comprehensive teaching learning-based training model on the skills and social attitudes of young football players.

Materials and methods. This is an experimental study with a sample of 36 male football athletes aged 10-12 years. Samples are players who registered and trained at the Real Madrid Foundation Yogyakarta football school. Samples attended training with a frequency of 3x/week with a minimum attendance of 80% in 20 weeks and were selected to participate in district or provincial football competitions. The instrument used for measuring football technical skills was the David Lee test, and for social attitudes the Prosocial and Antisocial Behavior Sport Scale (PABSS) questionnaire was used. The data analysis technique was the paired sample t-test.

Results. The results showed that the comprehensive teaching learning-based training model affected the skills and social attitudes of young football players. In the 10 year age group, there was an influence on skills of 1.497 and social behavior of 2.750, which means that it is influential. In the 11 year age group, it was found that the effect on skills was 0.506 and social behavior was -2.812, which means that there was no effect on social behavior. In the 12 year age group, it was found that the effect on skills was 0.19 and social behavior was 1.148, which meant that it affected.

Conclusions. Young football coaches can make a comprehensive teaching learning-based training model as a choice of strategies in the development of performance skills and personality.

Purpose. Soccer is one of the most popular sports worldwide. Soccer goalkeepers are more likely than outfield players to injure their upper extremities, particularly their shoulders. The Fédération Internationale de Football Association (FIFA) 11+ Shoulder Injury Prevention Program (FIFA 11+S) was developed to prevent upper extremity injuries. The aim of this study was to assess soccer goalkeepers’ and goalkeepers’ coaches’ awareness, implementation, and opinion of FIFA 11+S effectiveness in reducing upper extremity injuries.

Materials and methods. A self-administered questionnaire was developed and distributed to worldwide professional soccer goalkeepers and goalkeepers’ coaches. The survey was available in 10 different languages. The questionnaire consisted of questions covering the awareness, implementation, and goalkeepers’ and goalkeepers’ coaches’ opinion of the FIFA 11+ Shoulder Injury Prevention Program in reducing upper extremity injuries. Questions development was guided by several authors expert in sport medicine and injury prevention programs. 

Results. A total of 722 goalkeepers and goalkeepers’ coaches completed the survey. The vast majority (97.60%) of the participants were goalkeepers. Only 204 (28.25%) participants were aware of FIFA 11+S, and 155 (21.46 %) were implementing FIFA 11+S in their current practice. Participants who implemented FIFA 11+S reported a positive opinion about the program efficacy, with a score of 8.19 ± 0.93 out of 10. 

Conclusions. This study is the first to investigate goalkeepers’ and coaches’ awareness, implementation, and opinion of the effectiveness of the FIFA 11+S program in reducing shoulder injuries globally. Overall, the awareness rate was exceptionally low, but the implementation level among aware participants was good. Goalkeepers and coaches attained a positive score regarding the FIFA 11+S effectiveness in reducing shoulder injuries.

Published: March 2022

Research purpose. This study aims to compare anthropometric characteristics between elite and novice bodybuilders.
Materials and methods. Twenty bodybuilders consisted of 10 elites and 10 novices were recruited. Percent body fat, segmental lean mass, and segmental fat mass were measured by a bioelectrical impedance analysis device. Other measure includes the circumference of body segment and body height.
Results. Results of the study indicated that significant differences were found in terms of upper arm (flexed) circumference, upper arm circumference, and chest circumference, with the elite, were bigger than the novice. Elite bodybuilders also had significantly lower body fat percentage, with a better segmental lean mass of the right arm, left arm, and trunk. Interestingly neck, arm, waist, hip, thigh, and calf circumferences were not significantly different between groups. Similar insignificant differences were also found in body mass index, a segmental lean mass of right leg and left leg, a segmental fat mass of left and right arm, trunk, and left and right leg. With regards specifically to the group of bodybuilders that participated in this study, the non-significant differences variables may indicate areas that can be improved in terms of training in both elite and novice. The variables with significant differences may indicate the area that may have been over-emphasized by the elite group, which may also contribute to their better (winning) performance.
Conclusions. In a conclusion, the results also correspond well with bodybuilding judging criteria, where one of them such as size (circumference) may be similar, but bodybuilders with lean and well-defined bodies will be in the winning group.

Authors: ZAVALSIZ Şura , KIRIŞIK Fatih
Published: March 2022

Kovid-19 salgını ile mücadele eden Almanya’da eyalet hükümetlerinin birbirinden farklı uygulamaları ülkede önemli bir sorun oluşturmuştur. Federal hükümet Enfeksiyondan Korunma Yasasında değişiklikler yaparak, eyaletlerde bulunan bazı yetkileri merkezileştirmiştir. Böylelikle ulusal krizle mücadelede, ulusal düzeyde kararlar alınarak eyalet karar ve uygulamalarındaki farklılıklar ortadan kaldırılmıştır. Kovid-19 salgını sürecinde yaşanan bu gelişmeler, Alman Anayasasında yapılan 2006, 2009 ve 2017 reformlarıyla birlikte değerlendirildiğinde, Almanya’da federalizmden uzaklaşma yönünde bir gelişme olduğu dikkati çekmektedir. Bu kapsamda gerçekleştirilen çalışmanın amacı, bölünmüş otoritenin varlığı karşısında ulusal krizle mücadelede federalizmin yapısal sorunlarını ve Almanya’nın üniterleşme eğiliminde olduğu iddiasını incelemektir. Çalışma, Almanya'da 2019-2022 yılları arasında Kovid-19 salgınına yönelik yönetsel sorunları ve idari kararları kapsamaktadır. Federal devletin ulusal sorunlarla başa çıkma kapasitesinin Almanya örneğinde incelenmesi çalışmanın önemini göstermektedir. Çalışmada nitel araştırma yöntemi uygulanmış, literatür taraması ve içerik analizi yapılmıştır. Bu kapsamda, Kovid-19 salgını sırasında alınan idari ve hukuki kararlarla birlikte yetkililerinin söylemleri incelenmiştir. Çalışma sonucunda, Alman federalizminin gücünü koruduğu ancak federal devletin çok aktörlü yönetsel yapısının ulusal krizin çözümünde sorun yaşadığı görülmektedir.

Development of a New High-Oxygen Flow Nasal Device for Hypoxia Management in Patients With Pulmonary Limitation Arising from Covid-19 and Other Respiratory Diseases
Authors: Oliveira Alex , Lopes-Santos Lucilene , Cervigne Nilva Karla
Published: March 2022

Abstract About 5.5 million people in the world have respiratory limitations, which is the 5th largest cause of hospitalizations in Brazil. Covid-19 has contributed negatively to this scenario. The choice of adequate respiratory support contributes to a better clinical outcome, also supporting an improvement in quality of life. A new way of providing oxygen therapy, with lower cost and capable of managing hypoxia, may be a promising alternative. With the use of common supplies, it is possible to provide a high flow of compressed air and oxygen, heated and humidified, optimizing ventilation-perfusion. With a view to addressing hypercapnia and hypoxemia, this newly designed new form can contribute to clinical practice. The results of this study showed the effectiveness of this strategy when using flows from 30l/min, since, in this way, the loss of gas supply to the patient is insignificant. In addition, the financial viability makes the strategy accessible to less favored institutions. The magnitude of respiratory disorders aroused the need for new approaches to this clinical scenario, as conventional oxygen therapy does not always meet these demands and the high-flow nasal catheter has already shown a promising strategy in cases of respiratory limitations.

Resumo Cerca de 5,5 milhões de pessoas no mundo apresentam limitações respiratórias, sendo esta a 5ª maior causa de internações no Brasil. A Covid-19 tem contribuído negativamente para este cenário. A escolha do suporte respiratório adequado contribui para um melhor desfecho clínico, auxiliando também na melhora da qualidade de vida. Uma nova forma de oferta de oxigenoterapia, com menor custo e capaz de controlar a hipóxia, pode ser uma alternativa promissora. Com o uso de insumos comuns, é possível fornecer um alto fluxo de ar comprimido e oxigênio, aquecido e umidificado, otimizando a ventilação-perfusão. Com o objetivo de abordar a hipercapnia e a hipoxemia, esta nova forma recém-desenhada pode contribuir para a prática clínica. Nossos resultados mostraram a eficácia dessa estratégia ao utilizar fluxos a partir de 30l/min, pois, dessa forma, a perda de suprimento de gás ao paciente é insignificante. Além disso, a viabilidade financeira torna a estratégia acessível às instituições menos favorecidas. A magnitude dos distúrbios respiratórios despertou a necessidade de novas abordagens nesse cenário clínico, pois a oxigenoterapia convencional nem sempre atende a essas demandas e o cateter nasal de alto fluxo já se mostrou uma estratégia promissora em casos de limitações respiratórias.

Background: Sickle cell disease is one of the most common genetic disorders in the world, with a high prevalence in Africa. It is a pathology that threatens the maternal-fetal prognosis in case of pregnancy. The objective of this study was to describe the maternal-foetal complications and to identify the factors associated with maternal-foetal complications in sickle cell pregnant women (SP).Methods: This was a descriptive cross-sectional study with retrospective data collection over a period of 4 years (01 January 2015 to 31 August 2019). The study population was All SP who had given birth in the maternity ward of the UH of Borgou/Alibori.Results: We recorded 130 SP out of 10087 admissions, either a frequency of 1.3%. There were 119/130 exploitable files. Maternal complications during pregnancy were: vaso-occlusive crises 79%; severe anaemia 27.7%; hyponatremia 10.1%; vasculo-renal syndromes 18.4%; infections 74.8%. The foetal complications during pregnancy were: Preterm births 38.6%, in utero deaths 17.6%, low birth weight 54.7%. Early neonatal mortality was 8.4% (8/95). There was a 4.2% (5/119) of maternal deaths. Low educational level of the SP, SS genotype, insufficient antenatal follow-up and antenatal follow-up outside the specialized center for the care of sickle cell pregnant women (SCCSP) were the factors associated with maternal-foetal complications in the SP.Conclusions: The association of pregnancy and sickle cell disease is frequent in West Africa, particularly in Benin, and is characterised by numerous maternal-foetal complications that are associated with certain factors.

Results: Among the patients presented with first trimester vaginal bleeding, ectopic pregnancy was noted in 7%, hederiform mole in 3%, 17% aborted in the first trimester itself, 73% of patients that continued pregnancy after first trimester 3% had second trimester miscarriage.70% who reached beyond viability gestational age 52% delivered vaginally, out of which 27.14% had preterm delivery, 18% were delivered by caesarian section. The adverse perinatal outcome noted in the study were LBW (23, 32.85%), preterm birth (19, 27.14%), NICU admission (25, 35.71%), FGR (8, 11.43%) and intrauterine fetal death (2, 2.86%). The   maternal complication associated with pregnancy noted in the study were anemia (29,54.72%), PIH (6, 11.32%), placenta previa (5, 9.43%), placental abruption (3, 5.66%) and PPROM (8, 15.09%).Conclusions: There is positive correlation between first trimester vaginal bleeding and adverse feto-maternal outcome. The fetus is in increased risk of LBW, Preterm birth, NICU Admission, FGR and fetal death. The patients are in increased risk of having maternal complication like anemia, PIH, Placenta previa, Placental abruption and PPROM.

Background: Women are highly motivated and receptive to accept Family Planning (FP) methods during the postpartum period. Intrauterine Contraceptive Device (IUCD) is one of the commonly used reversible methods of contraception and provide very effective, safe and long-term protection against pregnancy and the health risks associated with the method are negligible. Taking advantage of the immediate postpartum period for counselling on family planning and IUCD insertion, overcomes multiple barriers to service provision. The increased institutional deliveries are opportunity to provide women easy access to immediate PPIUCD services. Objective-The aim of the study was to determine proportion of women accepting postplacental intrauterine contraceptive device insertion, and to describe the factors associated with acceptability and non-acceptance.Methods: Cross-sectional study conducted from September 2021 to October 2021 in 250 women admitted for delivery at Gadag institute of medical sciences, Gadag. The respondents were interviewed using structured interviewer administered questionnaire.Results: In the study, it is found that overall awareness regarding PPIUCD in the study population is only 32% which is comparable with the study findings of Rajasthan where the 8 awareness was 20.2%. The readiness rate for PPIUCD insertion after the counselling in present study was 8% which is similar the study report from Government Medical College, Trissur, Kerala where the acceptance rate 1 was 10.5%. The major factors associated with nonacceptance were refusal by patient (50%) and relatives.Conclusions: The emerging factors for less acceptance of PPIUCD are low literacy rate among women and infrequent counselling and education during antenatal period. Integration of a PPIUCD counselling service at every delivery point with provision of couple counselling can improve the success of this programme.

Background: Fetal blood flow can be studied by Doppler patterns which follow a longitudinal trend with sequential changes in umbilical artery, middle cerebral artery followed by other peripheral arteries. Though FGR cannot be treated but morbidity and mortality can be decreased by studying longitudinal changes in MCA-PI (middle cerebral artery-pulsatility index) and MCA-PSV (middle cerebral arterial-peak systolic velocity) and terminating the pregnancy at appropriate time.Methods: A prospective observational study was conducted from 2018 to 2019 on 29 antenatal patients with suspicion of fetal growth restriction at >32 weeks gestation. Patients with late onset FGR by Delphi procedure with singleton pregnancy and confirmed gestational age were included. Patients with gross congenital anomaly or multiple pregnancy were excluded. Peak systolic velocity, resistance index and PI in middle cerebral artery were recorded in absence of fetal movements. MCA-PSV >95th percentile and MCA-PI <5th percentile for that gestational age were considered abnormal. The compiled data was subjected to statistical analysis.Results: Mean gestational age was 36.28±1.6 weeks at enrolment and 36.65±1.56 weeks at delivery. The longitudinal changes in MCA-PSV values showed an increase in all the patients but in 11 patients, it was abnormal and out of these there was fall in 6 patients after an increase. MCA-PSV fall was strongly associated with perinatal mortality (p value 0.0003 and kappa 0.664). In 22 patients with increase in MCA-PSV there was decrease in MCA-PI while in 7 patients MCA PI increased which could be due to pseudo normalization phenomenon due to cerebral oedema. Association of MCA-PSV fall with adverse perinatal outcome was not significant (p value >0.05). The sensitivity of MCA-PSV fell in predicting the perinatal mortality was 80% and specificity was 91.76%.Conclusions: MCA-PSV not only complements MCA-PI but also provides more accurate information than does MCA-PI alone and should be used along with MCA-PI for optimizing fetomaternal outcome.

Published: March 2022

Background: Chemotherapy-induced myocardial dysfunction (CIMD) is a documented actuate of heightened morbidity and mortality. The gold standard for the surveillance of CIMD is the serial echocardiogram. Two-dimensional speckle echocardiography i.e. global longitudinal strain (GLS) is affirmative diagnostic tool than conventional echocardiography.Methods: We retrospectively reviewed the data of children (age between 6 months to 18 years) who received cardio-toxic chemotherapeutic agents and underwent echocardiography assessment with conventional and GLS imaging at-least 2 times between January 2020 to January 2021 in The Indus Hospital, Karachi at start, 3rd months and 6th months of treatment.Results: We enrolled 122 patients in our study. The mean age was 8.19±4.43. 82 (67.2%) children got the 2 echocardiographic evaluations while 40 (32.8%) children completed three. Of 82 subjects, 17 (22.6%) had a significant reduction in early myocardial deformation indices as measured by two-dimensional (2D) STE using GLS at the end of 3 months of chemotherapy. Before the start of therapy, mean values of ejection fraction (EF), fractional shortening (FS) and GLS were 68.6±10.44, 38.8±7.44, and -20.7±4.19 respectively. At 3rd month and 6th month follow up, EF decreased 65.80±9.00 and 62.06±10.62 (p value 0.000) respectively while the values for GLS decreased significantly as -18.4±3.86, -16.68±3.63 (p value 0.02) respectively.Conclusions: GLS is an effective, and non-invasive cardiac imaging modality than a conventional echocardiography in assessment of left ventricular (LV) dysfunction in non-symptomatic as well as in symptomatic children with cancers.

Background:  Neonatal hyperbilirubinemia is common morbidity in the first week of life. Approximately 5-10% of them requires intervention like phototherapy and even exchange transfusion. Phototherapy has various adverse effects and hypocalcemia is one of them. Thus assessment of serum calcium levels after phototherapy should be done in neonates with jaundice. Background: Neonatal hyperbilirubinemia is common morbidity in the 1st week of life. Approximately 5-10% of them requires intervention like phototherapy and even exchange transfusion. Phototherapy has various adverse effects and hypocalcemia is one of them. Thus, assessment of serum calcium levels after phototherapy should be done in neonates with jaundice. Objectives were to study prevalence of hypocalcemia in neonates with unconjugated hyperbilirubinemia receiving phototherapy and to observe association of hypocalcemia with duration of phototherapy.Methods: This was a prospective observational study conducted over a period of 18 months among 75 neonates (both term and preterm) in the neonatal intensive care unit of Manipal teaching hospital, Pokhara. Total serum calcium level was measured at 0 hours (control), 12 hours, and after 48 hours and data were analyzed using statistical package for social sciences version 21.Results: Hypocalcemia was found only in term neonates (n=8; 14%). Of those who had hypocalcemia, the majority experienced hypocalcemia after 48 hours of starting phototherapy. The mean difference of total serum calcium level before and after phototherapy in preterm and term neonates was found to be statistically significant. Hypocalcemia was not found to be associated with the duration of phototherapy.Conclusions: The present study concludes that though there is a reduction in the serum calcium with increased duration of phototherapy, however, it does not fall to the level where treatment is required. Hence it is not recommended to monitor serum calcium levels in neonates receiving phototherapy.

Background: Enteral feeding in preterm neonates with intrauterine growth restriction (IUGR) and absent or reversed end diastolic flow (AREDF) on umbilical artery (UA) Doppler is delayed owing to an increased risk of necrotizing enterocolitis (NEC). Delaying enteral feeding with longer duration of parenteral nutrition (PN) carries an increased risk of various neonatal morbidities.Methods: It was a prospective observational non randomized cohort study. Data was collected prospectively from the NICU records. Neonates fulfilling the inclusion criteria were classified as early feeding regimen and late feeding regimen. A strict feeding regimen was followed. Data was analyzed for primary and secondary outcomes.Results: The 50 neonates were enrolled. Baseline characteristics were comparable. A significantly higher time to full feeds was recorded in the delayed feeding regimen by a mean of 3.9 days. The duration of hospital stay was significantly higher for delayed feeding regimen (+12.7 days). Days of mechanical ventilation were also significantly higher (+1.6 days) in the neonates in delayed feeding group. There was no difference in the incidence of feed intolerance, NEC, incidence of culture positive sepsis and mortality across the two regimens, however neonates in the delayed feeding group needed longer support with parenteral nutrition.Conclusions: Early feeding will lead to earlier time to full feeds and decreased duration of hospital stay without additional increase the incidence of feeding intolerance and NEC in neonates with AEDF/REDF. Individualized feeding strategy in these compromised neonates should be the primary objective to optimize outcomes.

Background: Medical literature has reports of isolated cases of atrioventricular conduction disorders, supraventricular arrhythmias, and myocarditis in dengue fever (DF). There is a paucity of data available in the published literature on the cardiac manifestations of DF from India. The aim of the present study was to assess the cardiac manifestations of DF. Methods: The 140 patients aged ≥18 years with DF confirmed with a serology-dengue non-structural protein 1 antigen-positive were included for this prospective observational study. Three serial ECGs were taken on day one, day three and day seven or day of discharge. All the patients were evaluated using 2D echo on day one, day seven or day of discharge. The primary outcome measures were to find the incidence and type of echocardiographic abnormalities and electrocardiographic changes in dengue.Results: The incidence of cardiac abnormalities on ECG and 2D echo was 30 (21.4%), and 5 (7.0%) respectively. On ECG, 14 (10%) 9 (6.4%) 3 (2.1%) 3 (2.1%) and 1 (0.7%) patients had sinus bradycardia, sinus tachycardia, non-specific ST-T changes, right bundle branch block and atrio-ventricular block on ECG respectively. On 2D echo, 7 (5.0%), 5 (3.6%) and 1 (0.7%) patient had systolic dysfunction, ejection fraction (<45.0%) and diastolic dysfunction respectively.Conclusions: The incidence of cardiac abnormalities on ECG and 2D ECHO in dengue patients was considerable. ECG and 2 D echo should be undertaken in patients with DF.

Published: March 2022

Multiple myeloma is a neoplastic plasma cell dyscrasia. Anaemia in multiple myeloma is usually related to many factors, of which the commonest cause being anaemia of chronic disease. We reported a 67 years old hypertensive male presented with low back pain and loss of appetite. Investigations revealed severe anaemia and elevated total serum protein with albumin/globulin (A/G) reversal (1:4). Bone marrow aspiration revealed plasma cell dyscrasia. Skeletal survey evaluation showed multiple osteolytic lesions. Serum protein electrophoresis revealed M spike in gamma globulin region with immunofixation suggestive of IgG and kappa monoclonal gammopathy. He was diagnosed as a case of multiple myeloma.. On evaluating the cause of severe anaemia, interestingly various findings suggestive of Autoimmune hemolytic anaemia (AIHA) were found. Packed red blood cell transfusion along with steroids was done for correction of severe anaemia. Review of literature showed that only about 4% of AIHA patients had multiple myeloma. We reported a rare case of multiple myeloma who presented with AIHA.
