Introduction: Anatomical femoral tunnel placement is critical for anterior cruciate ligament reconstruction (ACLR). Tunnel placement may vary with different surgical techniques. The aim of this study was to compare the accuracy of femoral tunnel placement between the Anteromedial (AM) and Anterolateral (AL) visualisation portals on post-operative CT scans among a cohort of ACLR patients. Materials and methods: This cross-sectional study was conducted from January 2018 to March 2020 after obtaining ethics clearance. Patients who went for arthroscopic ACLR in our institute were divided into an AM (group 1) and an AL (group 2) based on the visualisation portal for creating the femoral tunnel and a 3D CT scan was done. The femoral tunnel position was calculated in deep to shallow and high to low direction using the Bernard Hertel grid. Femoral tunnel angle was measured in the 2D coronal image. Statistical analysis was done with the data collected. Results: Fifty patients with an average age of 26.36 (18-55) years ±7.216 SD were enrolled in the study. In this study, the AM technique was significantly more accurate (p<0.01) than the AL technique in terms of femoral tunnel angle. Furthermore, the deep to the shallow position was significantly (p= 0.018) closer to normative values, as determined by the chi-square test. The chances of error in tunnel angle in femoral condyle are 2.6 times greater in the AL technique (minimal clinical difference). Conclusion: To conclude, in ACLR the anteromedial visualisation portal can facilitate accurate femoral tunnel placement compared to the anterolateral visualisation portal.

Background and object:The burden of neurological disorders in India is expected to increase due to the rapid demographic and epidemiological transition,with irrational drug use,which is also a global concern.Thus,drug utilization evaluation is designed to ensure appropriate medicine use within the healthcare settings.The aim of the study was to assess the rate and pattern of drug utilization in the management of neurological disorders.Materials and methods:A hospital-based cross-sectional drug utilization evaluation study on neurological drugs was carried out at the Department of Neurology over a span of six months.All legible prescriptions consisting neurological medications irrespective of patient's gender,aged ≥18 years were included for the study.The World Health Organization(WHO)core drug use indicators were used to assess the drug prescribing and utilization patterns.Results:A total of 310 prescriptions were reviewed,where male predominance was found to be 56.45％.Out of 310 prescriptions,drugs belonging to 26 neurological classes were prescribed for the management of various neurological disorders.The majority of patients were diagnosed with epilepsy and the most prescribed drugs per patient were phenytoin(14.8％)and valproic acid(6.45％).By following the WHO core drug prescribing indicators,65.47％of drugs prescribed from the India National List of Essential Medicines,2022,followed by 29.83％of drugs prescribed in generic name and 10.86％of prescriptions including injections.Conclusion:The study findings showed that the prescribing pattern in the Department of Neurology was in accordance with the WHO core prescribing indicators.But,the extent of polypharmacy prescriptions was very high.Therefore,interventions are very necessary to promote rational drug prescribing patterns and thus clinical pharmacists can contribute to assess and review the drug utilization pattern to optimize the drug therapy and improvement in patient safety.

Objective: To explore the anticoagulant, antiplatelet and antioxidant activities of protein extract of kenaf seed (PEKS). Methods: Sodium dodecyl sulphate polyacrylamide gel electrophoresis and reverse-phase high-performance liquid chromatography techniques were employed for protein characterization. Antioxidant activity of PEKS was assessed using 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The protective effect of PEKS on sodium nitrite (NaNO 2) induced oxidative stress was evaluated using the in vitro red blood cell model, while the effect of PEKS on diclofenac-induced oxidative stress was examined in vivo in rats. Platelet-rich plasma and platelet-poor plasma were used for anticoagulant and antiplatelet activities of PEKS. Results: PEKS revealed similar protein bands on SDS-PAGE under reduced and non-reduced conditions. Several acidic proteins were present in native PAGE. PEKS showed antioxidant properties by scavenging DPPH with an IC 50 of 24.58 μg. PEKS exhibited a protective effect on NaNO 2 induced oxidative stress in red blood cells by restoring the activity of stress markers. In addition, PEKS alleviated diclofenac-induced tissue damage of the liver, kidney, and small intestine. PEKS showed an anticoagulant effect in both in vivo and in vitro experiments by enhancing normal clotting time. PEKS did not affect prothrombin time but increase activated partial thromboplastin time. Furthermore, PEKS inhibited adenosine diphosphate and epinephrine-induced platelet aggregation. Conclusions: PEKS protects tissues from oxidative stress and exhibits antithrombotic activity.

The incidence of type 1 diabetes mellitus (T1DM), an autoimmune disorder, has ascended considerably with around 98,200 and 15,900 incidents in children below 15 years of age, globally and in India, respectively. This is typically due to environmental changes leading to genetic modifications. Also, T1DM encompasses the presence of autoantigens and many other etiologies which can be targeted by proper immunization. In this paper, we consciously discuss and collate various candidate triggers of islet autoimmunity and other factors expected to promote progression of T1DM. This paper bridges all the mechanisms caused by these factors and linking them with each other. We have also highlighted on the novel corona virus as a trigger for T1DM. Finally, we suggest that an amalgamated model of polyvaccine can batter the condition by inducing protection against various triggers of T1DM.

The sigma-1 receptor (R) is a unique intracellular protein. R plays a major role in various pathological conditions in the central nervous system (CNS), implicated in several neuropsychiatric disorders. Imaging of R in the brain using positron emission tomography (PET) could serve as a noninvasively tool for enhancing the understanding of the disease's pathophysiology. Moreover, R PET tracers can be used for target validation and quantification in diagnosis. Herein, we describe the radiosynthesis, PET/CT imaging of novel R C-labeled radioligands based on 6-hydroxypyridazinone, [C]HCC0923 and [C]HCC0929. Two radioligands have high affinities to R, with good selectivity. In mice PET/CT imaging, both radioligands showed appropriate kinetics and distributions. Additionally, the specific interactions of two radioligands were reduced by compounds and (self-blocking). Of the two, [C]HCC0929 was further investigated in positive ligands blocking studies, using classic R agonist SA 4503 and R antagonist PD 144418. Both R ligands could extensively decreased the uptake of [C]HCC0929 in mice brain. Besides, the biodistribution of major brain regions and organs of mice were determined . These studies demonstrated that two radioligands, especially [C]HCC0929, possessed ideal imaging properties and might be valuable tools for non-invasive quantification of R in brain.

Objective: Social media usage is a global consumer phenomenon that has risen exponentially in the last few years. Published Indian studies on social media addiction are scarce and social media associated health issues are an emerging health problem in India. Objectives: To assess and compare social media addiction between private and public high-school students and to assess health problems related to social media usage across these groups. Methods: This crosssectional study was completed in 2016. It was conducted in five private and five public high schools across wards of Bengaluru city that were selected by simple random sampling. The subjects were students studying in grades 8, 9 and 10 (aged between 12 and 16 years). A total of 760 subjects were recruited, 380 from public and 380 from private high schools. They were administered a pretested, semi-structured, self-administrated questionnaire in either the local language or English. Univariate and multivariate logistic regression were employed to establish any associations between social media addiction and various other factors. Results: In our samples, 60.95% of social media users studied in private schools and 39.05% in public schools (z = 10.31, p<0.001). The most commonly used social media applications were, Internet gaming (69.23%) in Public schools and WhatsApp (61.15%) in Private schools. The overall prevalence of social media addiction was 19.96% among users with significantly higher rates of selfreported addiction in private schools (z = 3.47, p < 0.001). A total of 70.67% of the subjects had one or more physical symptoms, i.e. neck pain, tension, strain on eyes and fatigue of which 67.42% and 72.75% were from public and private schools, respectively. Psychological changes, i.e. anger, lonely and frustration; and behavioural changes, i.e. sleep disturbance and neglect personal hygiene were observed in 67.42% and 51.01% of public and private school pupils, (z = 3.85, p < 0.001), respectively. Conclusion: Private school students were more prone for social media addiction. Majority had mild addiction. Addiction was associated with behavioural changes. A multitude of physical, psychological and behavioural problems were observed among social media users.

The treatment of an above knee amputee who has sustained a fracture of the femoral neck is a chal- lenging situation for both the orthopedic surgeon and the rehabilitation team. These fractures may be managed acutely either by reduction and internal fixation or by endoprosthetic replacement based on the same criteria as in any other patient with otherwise intact limbs.We present a neglected case treated successfully with valgus osteotomy. We conclude that these fractures should be treated with the same urgency and expertise as similar fractures in non-amputees as long-term survival and good quality of life can be expected.
