A Comparative Study of Anterior Cruciate Ligament Reconstruction Versus Conservative Treatment.

Background The anterior cruciate ligament (ACL) rupture is a common injury with an incidence of 68.6 in 100,000 patients per year. Despite extensive research on ACL rupture, there are insufficient high-quality studies to determine clear treatment strategies for adults lacking the ACL. This study aims to examine the functional differences between surgical and conservative treatment based on the quality of the surgical process. Methodology In this prospective, comparative study, a total of 136 patients aged between 18 and 35 years were enrolled per inclusion and exclusion criteria. Using the lottery system, patients were divided into the following two groups: group A (n = 71) and group B (n = 65). Group A was treated with arthroscopic ACL reconstruction and rehabilitation, whereas group B was treated conservatively (rehabilitation). Patient data, including age, sex, body mass index, International Knee Documentation Committee (IKDC) score, Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner Activity Level (TAL) score, and complications were recorded and compared. Results The demographic data were comparable, where males had dominancy in both groups. The mean IKDC and KOOS scores were higher in group A at all follow-ups compared to group B. The scores gradually increased at every follow-up till six months. At the final follow-up, the IKDC and KOOS scores were higher in group A than in group B, and a significant difference was observed among both groups. The TAL score also gradually increased at every follow-up till 6 months. At the final follow-up, the TAL score was higher in group A than in group B, with a significant difference between the two groups (p = 0.0032). Complications in both groups were comparable. Conclusions This study showed that both the conservatively treated group and the rebuilt group had identical outcomes, with the exception of the conservative group having greater objectively quantifiable instability. However, at the final follow-up, patients reported feeling just as satisfied with their knee without surgery, demonstrating no subjective difference in activity levels or functional outcomes. Therefore, non-athletes with an ACL-insufficient knee should still choose conservative treatment.

A Joint Consensus of Rheumatologists and Dermatologists on Early Detection and Effective Management of Psoriatic Arthritis: India's Perspective.

Psoriatic arthritis (PsA) is a chronic inflammatory disease with clinical manifestations, including inflammatory arthritis and the presence of psoriasis (PsO). The present consensus statement evaluated the early diagnosis and treatment approaches in the management of psoriasis and psoriatic arthritis by rheumatologists and dermatologists. For PAN India representation, a panel of eight rheumatologists and five dermatologists from different institutes in India were constituted. These thirteen experts were divided into two groups (rheumatologists group and dermatologist group) who received a set of questionnaires each for diagnosis and treatment approaches in the management of psoriasis and psoriatic arthritis. Based on the responses received, a panel discussion took place, where the experts identified the early diagnostic criteria for PsA considering: Clinical signs and symptoms, and questionnaire-based PsA screening, which includes Psoriasis Epidemiology Screening Tool (PEST) for dermatologists and Classification Criteria for Psoriatic Arthritis (CASPAR) for rheumatologists. The experts also recommended shift from conventional disease-modifying anti-rheumatic drugs (DMARDs) to biologics like secukinumab, when there is extensive skin involvement and TNF inhibitors when there is extensive joint involvement. Overall, the objective of the consensus was to assist rheumatologists and dermatologists in the early diagnosis and management of patients of PsA and PsO in their clinical practice.

Assessment of chin morphology in different skeletal dysplasia - A cross-sectional study.

Objective: The objective of the study is to evaluate the morphology of the symphyseal region of adult skeletal Class II and Class III malocclusion as compared with Skeletal Class I subjects. Materials and Methods: The symphyseal width and height were evaluated using data from 80 lateral cephalograms of the age range of 18 years to 25 years. Average growing Skeletal Class II (n = 30) and Class III (n = 20) subjects were used as a comparison group. Average growing normal occlusion samples (n = 30) were used as controls. Results: Alveolar height was similar in all groups. The width of the symphyseal region including basal width, the width of the cervical region of the lower central incisor at the cementoenamel junction, and symphysis width were found to be similar in all groups. There is no significant difference in gonial angle in both Class II and III groups as compared to control. Articular angle showed no significant difference. Mandibular incisor dentoalveolar height (L1-AH) was found to be significantly higher in the Class II group (P < 0.05). Conclusions: There are no definite morphological differences in the symphyseal region between average grower Class I, Class II, and Class III skeletal malocclusions except mandibular incisor dentoalveolar height (L1-AH) and incisor mandibular plane angle which is higher whereas ramus length and body length which is lesser in Class II group as compared with controls. Width of the cervical region of the lower central incisor at the cementoenamel junction (Id-Id') and incisor mandibular plane angle was lower than control in Class III subjects.

Background Coronavirus disease 2019 (COVID-19) presents clinically a variety of pathological and clinical organ dysfunctions, ranging in severity from asymptomatic to fatal. The care and monitoring of COVID-19 patients may benefit from the use of biochemical and hematological markers. Objective To observe the alteration of serum biochemical and hematological parameters in COVID-19 positive patients, attending a Tertiary Care Hospital. Method A descriptive cross-sectional study was conducted on all COVID-19 positive patients attending Nobel Medical College Teaching Hospital, Biratnagar, Nepal from 15th December 2021 to 15th February 2022. The test results of different serum biochemical and hematological parameters done for these patients were recorded in clinical laboratory services and obtained retrospectively for the analysis. The data were entered in MS excel and analyzed by SPSS version 20. Result Out of 1537 COVID-11699 declared positive patients, 712 (46.32%) were male and 825 (53.68%) female. Mean age of COVID positive patients was 40.03±20.08 years. The level of serum SGOT, SGPT, ALP and GGT was significantly elevated in 39.9%, 42.8%, 32.3% and 47.2% of COVID positive patients respectively. Blood Urea, creatinine, uric acid and sugar level were significantly elevated in 63%, 56.1%, 33.1% and 47.6% patients respectively. The serum level of LDH, D-dimer, CRP and procalcitonin (PCT) were significantly increased in 52.1%, 75.9%, 71.6% and 61.2% of patients respectively. The serum value of total cholesterol, triglyceride, HDL and LDL were significantly lowered in 52.2%, 43.8%, 70.1% and 60.3% of patients respectively. RBC concentration and level of hemoglobin was reduced in 56.6% and 53.6% of COVID positive patients respectively whereas total leukocyte count was elevated in 80.7% with increase in neutrophil in 87.9% and decrease in lymphocyte in 79.4%. Conclusion A portion of COVID-19 positive patients showed drastically altered test results for various serum biochemical and hematological markers, although many of them had normal findings.

Antimicrobial resistance in neonates with suspected sepsis.

SETTING: Nobel Medical College and Teaching Hospital, Biratnagar, Nepal. OBJECTIVE: To determine the pattern of antimicrobial resistance and hospital exit outcomes in neonates with suspected sepsis in a tertiary neonatal intensive care unit (NICU). DESIGN: This hospital-based cohort study was conducted to follow patients from January to December 2019. All identified cases of suspected sepsis were enlisted from hospital records. RESULTS: Sepsis was suspected in 177 (88%) of the 200 cases admitted in the NICU; 52 (29%) were culture-positive. Pseudomonas was the predominant organism isolated (n = 40; 78%), followed by coagulase negative staphylococcus (n = 12, 23%). Nine (17%) of the 52 isolates were resistant to the Access and Watch group of antibiotics, including some resistance to Reserve group drugs such as imipenem and linezolid. Most treated cases (n = 170, 96%) improved, although 7 (4%) left against medical advice. CONCLUSION: Most of the pathogens were resistant to WHO Access and Watch antibiotics and occasional resistance was observed to Reserve group drugs. Most sepsis was caused by Gram-negative bacilli. Improving turnaround times for antibiotic sensitivity testing using point-of-care testing, and a greater yield of culture-positive results are needed to enhance the management of neonatal sepsis.

LIEU: Hôpital Universitaire Nobel Medical College, Biratnagar, Népal. OBJECTIF: Déterminer le profil de résistance antimicrobienne et les résultats au moment de la sortie d'hôpital chez des nouveau-nés avec suspicion de sepsis dans une unité néonatale de soins intensifs tertiaires (NICU). MÉTHODE: Cette étude de cohorte hospitalière a été réalisée pour suivre les patients de janvier à décembre 2019. Tous les cas identifiés de suspicion de sepsis ont été inclus à partir des dossiers hospitaliers. RÉSULTATS: Une suspicion de sepsis a été observée chez 177 (88%) des 200 cas admis en NICU ; 52 (29%) étaient positifs par culture. Pseudomonas était le micro-organisme prédominant (n = 40 ; 78%), suivi des staphylocoques à coagulase négative (n = 12, 23%). Neuf (17%) des 52 isolats étaient résistants aux groupes d'antibiotiques « dont l'utilisation est essentielle ¼ et « à utiliser sélectivement ¼, avec certaines résistances aux antibiotiques « de réserve ¼ comme l'imipénème et le linézolide. L'état de la plupart des cas traités (n=170, 96%) s'est amélioré, mais sept (4%) nouveau-nés sont sortis contre avis médical. CONCLUSION: La plupart des pathogènes étaient résistants aux antibiotiques des groupes OMS « dont l'utilisation est essentielle ¼ et « à utiliser sélectivement ¼, et quelques résistances ont été observées à certains « antibiotiques de réserve ¼. La plupart des sepsis ont été causés par des bacilles à Gram négatif. L'amélioration des délais d'exécution des tests de sensibilité aux antibiotiques à l'aide de tests au point de service et un meilleur rendement des résultats positifs par culture sont nécessaires pour renforcer la prise en charge du sepsis néonatal.

3D Echocardiography Provides Highly Accurate 3D Printed Models in Congenital Heart Disease.

Cardiac 3D printing is mainly performed from magnetic resonance imaging (MRI) and computed tomography (CT) 3D datasets, though anatomic detail of atrioventricular (AV) valves may be limited. 3D echo provides excellent visualization of AV valves. Thus, we tested the feasibility and accuracy of 3D printing from 3D echo in this pilot series of subjects with congenital heart disease (CHD), with a focus on valve anatomy. Five subjects with CHD were identified. 3D echo data were converted to 3D printable files and printed in collaboration with 3D Systems Healthcare (Golden, Colorado). A novel technique for valve modeling was utilized using commercially available software. Two readers (KM, SA) independently measured valve structures from 3D models and compared to source echo images. 3D printing was feasible for all cases. Table 1 shows measurements comparing 2D echo to 3D models. Bland Altman analysis showed close agreement and no significant bias between 2D and digital 3D models (mean difference 0.0, 95% CI 1.1 to - 1.1) or 2D vs printed 3D models, though with wider limits of agreement (mean difference - 0.3, 95% CI 1.9 to - 2.6). Accuracy of 3D models compared to 2D was within < 0.5 mm. This pilot study shows 3D echo datasets can be used to reliably print AV and semilunar valve structures in CHD. The 3D models are highly accurate compared to the source echo images. This is a novel and value-added technique that adds incremental information on cardiac anatomy over current methods.

Serum DHEA-S levels could be used as a comparable diagnostic test to assess the pubertal growth spurt in dentofacial orthopedics.

BACKGROUND: Pubertal growth spurt assessment guides the timing of intervention for correcting the skeletal discrepancies in dentofacial orthopedics. Serum hormones are being studied for the skeletal age assessment to avoid unnecessary radiographic exposure. The present study is to evaluate the relationship of serum hormones dehydroepiandrosterone-sulfate (DHEA-S), insulin-like growth factor (IGF-1), and cervical vertebral stages (CS stages) in the skeletal age assessment of orthodontics patients around the circumpubertal age. METHODS: A total of ninety subjects with age ranging from 7 to 21 years were selected and divided into two groups based on the sex (45 males, 45 females). They were further distributed in each group based on the six CS stages determined from the lateral cephalogram. Blood samples from each subject were collected to evaluate the serum DHEA-S and IGF-1 levels by using the enzyme-linked immunosorbent assay (ELISA). Collected data were analyzed in SPSS software with a test of normalcy, unpaired t test, and one-way analysis of variance (ANOVA) followed by the least significant difference (LSD) post hoc comparison test and univariate regression analysis. RESULTS: The highest mean serum hormone levels were found in CS 4 in group A (male) and CS 3 in group B (female). ANOVA results showed that there was a significant difference in the serum hormone levels among the different CS stages in both the groups for both the hormones. Statistically, a significant difference was found between each CS stages for both the hormones except in the DHEA-S levels between CS 5 and CS 6. CONCLUSIONS: The mean serum DHEA-S levels followed a typical pattern from the CS 1 till CS 6 which was comparable and similar to the mean serum IGF-1 levels in respect to CS stages. Thus, serum DHEA-S levels could be used as a possible diagnostic test for the assessment of the skeletal pubertal growth spurt in dentofacial orthopedics.

Giant Extra-Articular Synovial Chondromatosis of the Ankle Joint - A Rare Case Report.

INTRODUCTION: Synovial chondromatosis (SC) commonly involves large joints such as the knee and hip with smaller joints being less frequently involved. Extra-articular involvement is very rare, and here, we are presenting the first case of giant extra-articular SC originating from the ankle joint. CASE REPORT: A 42-year-old male presented to the outpatient department with painless swelling over the lateral malleolus for 2 years. Diagnostic imaging suggested the involvement of the synovial lining with the swelling. The mass was excised and histopathology proved the diagnosis of SC. CONCLUSION: Extra-articular involvement in SC has been mainly reported in the synovial sheath or bursae of the hand and foot, but they can involve ankle joint also. In recent times, there have been concerns about potential malignant transformation of these lesion to chondrosarcoma, diagnosing these lesions have become important.

Is High Altitude a Risk Factor in Development of Herpes Zoster?

Singh, G.K., Mahendra Singh Deora, Rajan Grewal, A. Kushwaha, and Sukhmeet Minhas. Is high altitude a risk factor in development of herpes zoster? High Alt Med Biol. 19:244-248, 2018. BACKGROUND: Old age immune-compromised states are known to increase the risk of herpes zoster (HZ). The aim of this study was to find out whether arrival into high altitude poses a risk for the development of HZ in lowlanders. METHODS: A retrospective study of 173 cases of HZ was carried out between January 1, 2005 and December 31, 2010 in people working at high altitude areas of Leh. Data of lowlander people working at high altitude were compared with that of high altitude native and similar group of people working at plains during the same period. RESULTS: HZ constitutes 2.36% (95% confidence interval [CI], 2.04-2.73) of total skin outpatient department cases at a hospital at high altitude, whereas it was 0.23% (95% CI, 0.18-0.29) at a tertiary hospital at plains. In lowlanders working at high altitude, frequency of herpers zoster varied between 2.63% and 3.59% with mean of 3.07%. Frequency of HZ in persons presenting to a tertiary dermatological center at plains varied from 0.19% to 0.26% (mean of 0.23%). Presence of high altitude posed a risk of almost seven times in developing HZ in comparison with its absence with odds ratio of 7.21 and 95% CI varying from 5.42 to 9.60. This result was statistically very significant with p value <0.0001. CONCLUSIONS: Lowlanders working at high altitude are at high risk to develop HZ in comparison with persons working at plains. However, a large population-based study is required to investigate and establish the same.

QRS detection using adaptive filters: A comparative study.

Electrocardiogram (ECG) is one of the most important physiological signals of human body, which contains important clinical information about the heart. Monitoring of ECG signal is done through QRS detection. In this paper, an improved QRS detection algorithm, based on adaptive filtering principle, has been designed. Enumeration of the effectiveness of various LMS variants used in adaptive filtering based QRS detection algorithm has been done through fidelity parameters like sensitivity and positive predictivity. Whole family of LMS algorithm has been implemented for comparison. Sign-sign LMS, sign error LMS, basic LMS and normalized LMS are re-implemented, while variable leaky LMS, variable step-size LMS, leaky LMS, recursive least squares (RLS), and fractional LMS are novel combination presented in this paper. After analysis of the obtained results, performance of leaky-LMS algorithm is found to be the best with sensitivity, positive predictivity, and processing time of 99.68%, 99.84%, and 0.45s respectively. Reported results are tested and evaluated over MIT/BIH arrhythmia database. Presented study also concludes that the performance of most of the variants gets affected due to low SNR but the Leaky LMS performs better even under heavy noise conditions.

An efficient closed-form design method for nearly perfect reconstruction of non-uniform filter bank.

In this paper, an efficient closed form method for the design of multi-channel nearly perfect reconstruction of non-uniform filter bank with the prescribed stopband attenuation and channel overlapping is presented. In this method, the design problem of multi-channel non-uniform filter bank (NUFB) is considered as the design of a prototype filter whose magnitude response at quadrature frequency is 0.707, which is exploited for finding the optimum passband edge frequency through empirical formula instead of using single or multivariable optimization technique. Two main attributes used in assessing the performance of filter bank are peak reconstruction error (PRE) and computational time (CPU time). As compared to existing methods, this method is very simple and easy to implement for NUFBs. To implement this algorithm, a Matlab program has been developed, and several examples are presented to illustrate the performance of proposed method.

Hybrid method based on singular value decomposition and embedded zero tree wavelet technique for ECG signal compression.

BACKGROUND AND OBJECTIVE: In the field of biomedical, it becomes necessary to reduce data quantity due to the limitation of storage in real-time ambulatory system and telemedicine system. Research has been underway since very beginning for the development of an efficient and simple technique for longer term benefits. METHOD: This paper, presents an algorithm based on singular value decomposition (SVD), and embedded zero tree wavelet (EZW) techniques for ECG signal compression which deals with the huge data of ambulatory system. The proposed method utilizes the low rank matrix for initial compression on two dimensional (2-D) ECG data array using SVD, and then EZW is initiated for final compression. Initially, 2-D array construction has key issue for the proposed technique in pre-processing. Here, three different beat segmentation approaches have been exploited for 2-D array construction using segmented beat alignment with exploitation of beat correlation. The proposed algorithm has been tested on MIT-BIH arrhythmia record, and it was found that it is very efficient in compression of different types of ECG signal with lower signal distortion based on different fidelity assessments. RESULTS: The evaluation results illustrate that the proposed algorithm has achieved the compression ratio of 24.25:1 with excellent quality of signal reconstruction in terms of percentage-root-mean square difference (PRD) as 1.89% for ECG signal Rec. 100 and consumes only 162bps data instead of 3960bps uncompressed data. CONCLUSION: The proposed method is efficient and flexible with different types of ECG signal for compression, and controls quality of reconstruction. Simulated results are clearly illustrate the proposed method can play a big role to save the memory space of health data centres as well as save the bandwidth in telemedicine based healthcare systems.

Pattern of chilblains in a high altitude region of Ladakh, India.

BACKGROUND: Extreme sub-zero temperature in winters (15 °C to -25 °C), high velocity winds and wind-chill factor pose risk to those who resides at the high altitude environment to develop cold related injuries like chilblains and frostbite. The aim of this study was to study the patterns of chilblains in high altitude region like Ladakh. METHODS: The study was conducted at Dermatology outpatient department of Military Hospital, Leh from 1 Sep 2009 to 31 May 2010. Patients, satisfying clinical criteria for the diagnosis of chilblains were included into the study. Detailed history and thorough clinical examination was conducted. Complete blood count and Urine routine examination was carried out in every patient. Anti Nuclear Factor tests were carried out in only those who had history suggestive of connective tissue disease. RESULTS: Total 108 (5.75%) were diagnosed to have chilblains. Only a single case of chilblain was found in a local resident (p < 0.005). Family history of chilblains was present in 10 (9.2%) patients, there was recurrence in 12 (11.1%) and 21 patients (19.4%) were smokers. Most (63.8%) of the patients, had BMI between 20 and 22 kg/m(2) (mean = 20.03 kg/m(2); 95% CI = 19.68-20.38 and SD 1.82). 42.1% of cases of chilblains also had hyperhidrosis (p < 0.05). CONCLUSION: In a HA area like Ladakh, the non-natives suffer maximum from chilblains. This could be explained by the protective genetic adaptability of natives to extreme cold environment and their protective life style against cold. Low body mass index (BMI) and hyperhidrosis are important associations for development of chilblains.
