    Background: There is a vast improvement in the survival and quality of life of patients with both major and minor structural and functional cardiac defects. Objective of present study was to calculate CARPREG (CARdiac disease in PREGnancy) risk score and test its efficacy in predicting the occurrence of adverse maternal cardiac events in patients with heart disease.Methods: This was a prospective observational study where CARPREG score was calculated for 100 pregnant patients as soon as they were enrolled and the degree of risk and maternal complications were recorded and studied in relation to the score.Results: Out of the 100 patients included in our study, it was found that Rheumatic heart disease (69%) with isolated mitral stenosis was the predominant cardiac problem. Maternal cardiac events complicated 14% pregnancies with congestive cardiac failure occurring most frequently. The complication rate was 1.56%, 5.56% and 66.67% in patients with CARPREG score of 0, 1 and ≥2 respectively. The sensitivity, specificity, positive predictive value and negative predictive value of CARPREG score in predicting the complications were 66.67%, 97.56%, 85.71% and 93.02% respectively. Hence, the score was efficacious in predicting the maternal cardiac complications and was found to be a statistically significant predictor of maternal complications (p value=7.39E-06).Conclusions: The CARPREG risk index has a high specificity and negative predictive value with regards to cardiac complications in pregnant women with heart disease. It may, therefore, be routinely used to improve the assessment of cardiac risk before and during pregnancy

    Objectives: The main focus of the present study was to evaluate the antimicrobial efficacy (against oral pathogenic bacteria), free radical scavenging activity, and total phenolic and flavonoids content (TPC and TFC) of methanolic extract (ME) of J. regia obtained from Kashmir region. Methods: The plant part was collected and its ME was prepared. ME was subjected to antibacterial activity against oral bacteria such as Staphylococcus aureus, Streptococcus mutans, and Pseudomonas aeruginosa. The free radical scavenging activity was determined using 2,2-diphenyl- 1-picrylhydrazylhydrate (DPPH) assay. TPC and TFC were also determined using a standard curve equation of gallic acid and quercetin. A standard curve using different concentrations of gallic acid and quercetin was drawn from which the concentration of phenols in the test sample was calculated and expressed in mg/g. Results: The ME of J. regia was found effective against all the strains of microorganisms responsible for oral infection understudy. It was also observed that scavenging of DPPH increased with the increase in concentration for both standard ascorbic and methanolic bark extract of J. regia showing its antioxidant potential. The TPC and TFC of ME was found to be 43.35±0.079 and 17.28±0.125. Conclusions: The results obtained from the study clearly indicate that the walnut bark from Kashmir region can be a good candidate for employment as an antibacterial against oral pathogens. J. regia bark was found to be a good source of healthy compounds such as phenolic and flavonoids, suggesting that its bark could be useful to prevent diseases in which free radicals are present

    Most bacteria are becoming resistant to almost all of the currently recommended drugs, leading to difficulty in their treatment. The present study focused on evaluating the therapeutic potential of Piper longum fruit extracts in terms of bactericidal, antioxidant and phytochemical evaluation by conducting antibacterial sensitivity tests against four multidrug-resistant Salmonella strains (Salmonella enterica subsp. arizonae, Salmonella Newport, Salmonella enterica ser. Typhi, and Salmonella enterica ser. Paratyphi) obtained from the Institute of Microbial Technology (IMTECH), Chandigarh. The Agar Well Diffusion method and the Minimum Inhibitory concentration (MIC) methods were performed to implement the anti-sensitivity test of crude extracts of the plant. The present study showed that the MIC of the P. longum  was between 0.25-0.0625mg/ml, which was lowest in the aqueous extract at 0.5mg/100µl, and the highest in the methanol extract (1mg/100µl). The Minimum Bactericidal Concentration (MBC) was lowest in aqueous (0.5mg/100µl) and highest in methanol plant extract (1mg/100µl). The methanol extract had the maximum antibacterial potency, whereas the aqueous extract had the lowest. The antioxidant capacity of the plant extracts was determined using a DPPH assay. Methanol plant extract revealed the highest antioxidant power (81.92%) and the lowest was found in the aqueous extract (62.84%). The GC-MS approach identified active bioingredients, important botanicals including caryophyllene, eicosane, and piperazine (potent antibacterial agent) as naphthyridine (having antimicrobial, anticancer, and anti-inflammatory activities), among others. The unique aspect of the study was the effectiveness of P. longum against Salmonella strains that are resistant to multiple antibiotics. This suggests that P. longum can be a great source of novel antibacterial compound for the development of herbal formulations

    Background: Musculocutaneous nerve variations may become evident clinically or may be encountered during surgery. These are of importance for neurologists, traumatologists and orthopaedicians.Methods: 70 upper limbs from 35 embalmed cadavers were studied during the study period of 2 years during routine dissection in the Department of Anatomy S.M.S. Medical College, Jaipur, India.Results: A branch from musculocutaneous nerve arising at a distance of 6 cm from acromion process of scapula.A branch arising from median nerve at a distance of 14.4 cm from acromion process and joins with the branch of musculocutaneous nerve at around 17.4 cms away from the acromion process. The nerve thus formed by the union of the branches from median and musculocutaneous nerves further goes and joins the Radial nerve just before entering the cubital fossa.Conclusions: While performing shoulder surgery, the palpation of musculocutaneous nerve is of great importance, as it may get injured by the retractors which are placed under the coracoid process during the surgery. Frequent shoulder dislocation, coracoid process grafting and arthroscopy might damage the nerve as well as the muscle. This article might fulfil the gap in the original research work in this field.

    Get PDF
    Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening syndrome of excessive activation of immune system. It frequently affects infants from birth to 18 months of age, but is also observed in children and adults of all ages. HLH can occur as a familial or sporadic disorder, and it is triggered by a variety of events, Infection being the most common trigger both in familial and in sporadic cases. Prompt treatment is very critical in cases of HLH, but the greatest barrier is often delay in diagnosis due to the rarity of this syndrome, variable clinical presentation, and lack of specificity of the clinical and laboratory findings. The key clinical features of HLH are high persistent fever, hepatosplenomegaly, blood cytopenia, elevated aminotransferase and ferritin levels, and coagulopathy. A diagnosis of HLH is mostly under-recognized, and is associated with high mortality, especially in adults; thus, prompt diagnosis and treatment are essential. We here present a rare case of HLH in an adult which was non-familial and infection being the trigger causing secondary hemophagocytic lymphohistiocytosis
