Potential of X-ray imaging to detect citrus granulation in different cultivars with progress in harvesting time

Granulation, a physiological disorder of citrus is manifested by shriveled juice sacs and internal dryness. Extractable juice in granulated tissue is drastically reduced as a consequence of gelatinization and secondary epidermis formation. Since, the defect cannot be detected externally it leads to consumer dissatisfaction and poor returns to farmers. Processing industry also faces huge economic loss due to reduction in the juice recovery from granulated fruit. In this context, here, we studied the possibility of developing an image processing algorithm through MATLAB software to detect granulation with advancement of maturity via X-ray micrographs. Fruit of eight citrus cultivars comprising of granulation susceptible and tolerant varieties harvested at four different intervals were exposed to X-rays. Voltage of 46 kV and current of 6.5 mA given to fruit for an exposure time of 320 mAs gave the best X-ray image contrasts. The developed algorithm could effectively distinguish the healthy and granulated fruit with an accuracy of 90% as validated by subsequent destructive analysis when estimated for four different harvesting dates. The imaging technique can be employed by the processors to determine the severity of granulation and to sort out fruit online which will help in saving economic losses.

Anesthesia- patient’s apprehension, concerns, and counseling

Introduction: To allay anxiety and resolve the patient’s apprehension regarding general anesthesia through counseling. Patients presenting to PAC were asked to participate in a 2-way conversation meant to evaluate and study his apprehension, concerns in relation to anesthesia, and subsequently, a counseling session was given to answer his doubts and resolve his fear. Material and Methods: In the study, it was found the fear of death was the greatest concern. The other major concerns were fear of paralysis and heart attack. Results: The level of fear decreased as the severity of surgery decreased. For major surgery, the fear of death differed significantly with age, especially with increasing age came a lessened fear of death. Counseling by anesthesia provider regarding the fear that the patient reported help to reduce the anxiety. It allows for a more personalized approach towards the patient. It helps anesthesia provider to tailor the informed consent process. Conclusion: In general, the study increases awareness regarding anesthesia among patient and their relatives.

Trends in the profile of non hodgkins lymphoma in North and South India: a study from two tertiary care hospitals in India

Background: A number of environmental and chemical factors have been thought to been implicated in the occurrence of Non-Hodgkin’s Lymphomas (NHLs).To fill the knowledge gap in various aspect of the disease, this study was undertaken at this tertiary care centre in Delhi and Bangalore.Methods: This was a prospective observational study conducted in two defenses medical centre in India among patients of Non Hodgkins Lymphoma, registered at Command hospital Airforce Bangalore and Army Hospital (Research and Referral), New Delhi, between March 2016 and March 2019.Results: The disease showed a bimodal onset in both centres with 26 (26%) and 24 (24%) cases occurring in the age group of 31-40 years and 24 (24%) and 25 (25%) cases occurring in the age group of >60 years at CHAF (B) and AH (RR) respectively. B cell Lymphoma was the most common type of NHL seen in 85% and 89% patients, whereas T-cell lymphomas constituted 13% and 11% at CHAF (B) and AH (RR).  32(32%) patients presented with an Ann Arbor Stage 1 or 2 disease whereas 68(68%) patients were with Stage 3 or 4 disease at both the centers. IPI score was ≥3 in 45 % and 43% patients.Conclusions: NHL in India is a homogeneous and uniform disease. But there was increased detection of hepatosplenomegaly and associated hepatitis B/C in the southern part of India. Also, the occurrence of Cutaneous T cell lymphoma was only seen in the south India centre. The early stage NHLs has better survival and increase chance of complete response.

Study of bone formation marker levels in rheumatoid arthritis

Background: Rheumatoid arthritis (RA) is an autoimmune disease of unknown cause that affects the joints principally. The disease affects between 0.5% and 1% of the adult population worldwide. Two to three times as many women as men suffer from the disease. Osteocalcin (OC) is a small protein of 49 amino acids long. OC is the most abundant non-collagenous protein in bone. OC originates from osteoblasts and is deposited into bones or released into circulation, where it correlates with histological measures of bone formation. Bone alkaline phosphatase (ALP) is a glycoprotein that is found on the surface of osteoblasts. This enzyme reflects the biosynthetic activity of these bone-forming cells. The presence of OC and ALP in the circulation may, therefore, provide a specific chemical index of osteoblastic activity. Objectives: This study was undertaken to estimate the values of serum OC and ALP among patients with RA and healthy control groups and to compare and find out any changes in levels of serum OC and ALP between the study and control groups. Materials and Methods: It was a case–control study done on 76 RA patients and 76 age- and sex-matched healthy individuals. Serum OC and serum ALP values were evaluated among all 76 cases and 76 controls. Serum OC was measured using immunoenzymatric assay and ALP was measured by colorimetric method. Statistical analysis was performed and results were tabulated and analyzed. Results: Mean ± standard deviation of serum OC level is significantly higher (P < 0.001) among cases (18.50 ± 8.72 ng/ml) than controls (9.98 ± 7.68 ng/ml). Similarly, the values of ALP are higher (P < 0.001) among cases (216.22 ± 59.96 IU/L) than controls (164.17 ± 50.70 IU/L). A significantly positive correlation was found between serum OC and serum ALP levels. Patient with the highest mean value of serum OC also has the highest values of ALP. The values of serum ALP and OC levels increase significantly in both early and late stages when compared with control values. Conclusions: A significant difference between the values of serum OC and ALP among cases and controls was seen in the study. Levels of both these parameters are elevated in subjects with RA compared to controls. Furthermore, the levels of serum OC correlated with the levels of serum ALP. This study demonstrates that increased bone formation is associated with RA together with bone resorption.

Lefamulin: novel pleuromutilin drug for community acquired bacterial pneumonia

The advent and spread of antimicrobial resistance has led to a global public health emergency necessitating development of new antimicrobial drugs. Community acquired bacterial pneumonia (CABP) contributes a major portion of societal burden with increasing morbidity due to evolution of drug resistant strains. Lefamulin is a novel pleuromutilin antibiotic with unique mechanism of action through inhibition of protein synthesis by binding to the peptidyl transferase center of the 50s bacterial ribosome. The drug displays activity against Gram positive and atypical organisms associated with CABP (i.e., Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumonia, Legionella pneumophila, and Chlamydophila pneumoniae), with an expanded Gram-positive spectrum including Staphylococcus aureus (i.e., methicillin-resistant, vancomycin-intermediate, and heterogeneous strains). Lefamulin is available in both intravenous (IV) and per oral (PO) formulation, exhibits high nonlinear plasma protein binding with low unbound concentrations, higher concentrations in lung epithelial lining fluid (ELF) than in plasma, and a half-life of approximately 10 hour. The recommended IV dose is 150 mg twice daily over 1 hour or a PO dose of 600 mg twice daily. Most common adverse drug reactions injection site reactions, hepatic enzyme elevation, nausea, diarrhoea, hypokalemia, insomnia, and headache. Clinical trials for lefamulin have been positive and Phase 3 data suggest similar efficacy when compared to moxifloxacin with or without linezolid in CABP. Also, the documented resistance and cross-resistance with other Gram-positive antibacterials remains low. With Nabrivia Pharmaceuticals having already received US FDA approval in August 2019, lefamulin may soon be a new addition to the mounting armoury of drugs against CABP.

Esta información debe ser transmitida al paciente y al departamento clínico emergentológico

Priapism is an urological emergency and must be diagnosed and treated appropriately. Specifically in known cases of leukemia painful turgid penis should raise suspicion of priapism in first hand and penile Doppler should be the first line of imaging modality. This information should be forwarded to patient and emergency department clinician

Side scatter versus CD45 flow cytometric plot can distinguish acute leukaemia subtypes.

Background & objectives: Flow cytometry is an important tool to diagnose acute leukaemia. Attempts are being made to find the minimal number of antibodies for correctly diagnosing acute leukaemia subtypes. The present study was designed to evaluate the analysis of side scatter (SSC) versus CD45 flow dot plot to distinguish acute myeloid leukaemia (AML) from acute lymphoblastic leukaemia (ALL), with minimal immunological markers. Methods: One hundred consecutive cases of acute leukaemia were evaluated for blast cluster on SSC versus CD45 plots. The parameters studied included visual shape, CD45 and side scatter expression, continuity with residual granulocytes/lymphocytes/monocytes and ratio of maximum width to maximum height (w/h). The final diagnosis of ALL and AML and their subtypes was made by morphology, cytochemistry and immunophenotyping. Two sample Wilcoxon rank-sum (Mann Whitney) test and Kruskal-Wallis equality-of-populations rank tests were applied to elucidate the significance of the above ratios of blast cluster for diagnosis of ALL, AML and their subtypes. Receiver operating characteristic (ROC) curves were generated and the optimal cut-offs of the w/h ratio to distinguish between ALL and AML determined. Results: Of the 100 cases, 57 of ALL and 43 cases of AML were diagnosed. The median w/h ratio of blast population was 3.8 for ALL and 1 for AML (P<0.001). ROC had area under curve of 0.9772.The optimal cut-off of the w/h ratio for distinction of ALL from AML was found to be 1.6. Interpretation & conclusions: Our findings suggest that if w/h ratio on SSC versus CD45 plot is less than 1.6, AML may be considered, and if it is more than 1.6, ALL may be diagnosed. Using morphometric analysis of the blast cluster on SSC versus CD45, it was possible to distinguish between ALL and AML, and their subtypes.

Heparin Co-factor II Thrombin Complex as a Biomarker for Mucopolysaccharidosis: Indian Experience.

Background: Serum heparin cofactor II-thrombin complex (HCII-T) is an emerging biomarker for mucopolysaccharidosis disease (MPS I and MPS II). Methods: Seventeen cases (6 MPS I and 11 MPS II) and sixty healthy controls were enrolled in study, conducted from September 2008 to December 2012. The mean ± SD age of MPS1 (n=6, 5 males) and MPS II was 7.02 ± 3.25 and 5.2 ± 2.15 years, respectively. Disease status was confirmed by clinical features and enzyme assay. Urinary glycosaminoglycans were measured in spot urine samples and expressed in relation to creatinine content. HCIIT measurement was done using sandwich ELISA at enrolment and after 12 and 24 months of recruitment. Results: Urinary glycosaminoglycans and HCIIT were elevated in all patients compared to their healthy controls. Both markers could not discriminate between the type of mucopolysaccharidosis. Conclusion: Heparin Cofactor II Thrombin Complex is a good biomarker for mucopolysaccharidosis I and II.

Consensus Statement of the Indian Academy of Pediatrics on Integrated Management of Severe Acute Malnutrition.

Justification: Severe acute malnutrition (SAM) is a major public health issue. It afflicts an estimated 8.1 million under-five children in India causing nearly 0.6 million deaths. The improved understanding of pathophysiology of SAM as well as new internationally accepted growth charts and newer modalities of integrated intervention have necessitated a relook at IAP recommendations. Process: A National Consultative Meeting on Integrated Management of Severe Acute Malnutrition was held in Mumbai on 16th and 17th October, 2010. It was attended by the invited experts in the field. Extensive discussions were held as per the program. The participants were then divided into six groups for detailed discussions. The groups deliberated on various issues pertaining to the task assigned and presented recommendations of the groups in a plenary session. The participants made a list of recommendations after extensive discussions. A Writing Committee was formed and was entrusted with the task of drawing a Consensus Statement on the basis of these Recommendations. After multiple deliberations, the following Consensus Statement was adopted. Objectives: To critically evaluate the current global evidence to formulate a consensus among stakeholders regarding diagnosis and management of SAM. Recommendations: An integrated management of malnutrition is likely to yield more dividends. Thus, management of SAM should constitute an important component of Integrated Management of Neonatal and Childhood Illnesses (IMNCI) program. Determination of SAM on the basis of Z-scores using WHO Growth charts is considered statistically more appropriate than cut-offs based on percentage weight deficit of the median. Considering the fact that many children with SAM can be successfully managed on outpatient basis and even in the community, it is no more considered necessary to advise admission of all children with SAM to a healthcare facility. Management of SAM should not be a stand-alone program. It should integrate with community management therapeutic programs and linkages with child treatment center, district hospitals and tertiary level centers offering inpatient management for SAM and include judicious use of ready-to-use-therapeutic Food (RUTF). All sections of healthcare providers need to be trained in the integrated management of SAM.

Prevalence of celiac disease in north indian children.

Celiac disease (CD) is being increasingly reported from the wheat-eating population of north India. However, the exact prevalence of CD in children is not known as population screening studies are scarce. Our study aimed to determine the prevalence of CD in 400 children, 6 months to 12 years of age attending pediatrics department of a tertiary care hospital in north India. The study population was screened for anti-tissue transglutaminase (tTG) antibodies. Endoscopic duodenal biopsy was done in the anti–tTG positive subjects. Four patients were diagnosed with CD as per the modified ESPGHAN criteria. The prevalence of CD thus was 1%, which was in concordance with screening studies using serological markers conducted in the West.

Current trends in the management of beta thalassemia.

The management of Beta Thalassemia, the commonest form of hemolytic anemia in children, has changed significantly in the last few years. With the availability of better transfusion regimen, iron chelation therapy, proper management of complications and good supportive care, it is now possible for a thalassemic child to have a near normal life span with a good quality of life.

Deferasirox: the new oral iron chelator.

Deferasirox is a new tridentate oral iron chelator developed by computer remodeling recently approved by FDA for children above 2 years. Phase II/III trials have demonstrated similar efficacy to desferrioxamine and better chelation efficiency. Adverse events were minor and growth remained unaffected. Data on cardiac iron chelation is limited although some studies have shown it comparable to deferiprone. The benefit to risk profile of deferasirox is favorable. This promising new drug might decrease the burden of subcutaneous or intravenous infusion improving compliance and hence the life expectation in thalassemic patients.

Safety and reactogenicity of a low dose diphtheria tetanus acellular pertussis vaccine (Boostrix) in pre-school Indian children.

OBJECTIVE: To evaluate the safety and reactogenicity of a reduced-antigen-content combined Diphtheria Tetanus Acellular Pertussis (dTpa) vaccine in Indian preschool children. METHODS: GlaxoSmithKline Biologicals combination dTpa vaccine was administered as a single booster dose to 347 children aged 46 years in seven centers across India. All children were subsequently followed up for two weeks for safety and reactogenicity assessment. RESULTS: A total of 345 subjects completed the study and two subjects were lost to follow-up. One serious adverse event (head injury) unrelated to vaccination was reported. Otherwise, all subjects were in good health throughout the study period. Three subjects (0.9%) reported transient general symptoms (such as irritability and drowsiness), which prevented normal activity. Pain at injection site, swelling and redness was reported in 31.1%, 18.2% and 8.9% subjects respectively. Five subjects (1.4%) reported severe pain preventing normal movement. This resolved within 48 hours in all cases. There were no other severe local reactions including large injection site reactions. CONCLUSION: The reduced antigen content combined dTpa vaccine is safe and well tolerated in Indian pre-school children.

Effect of salicylic acid on morphological and biochemical attributes in cowpea.

Effects of salicylic acid (SA) on seed germination, seedling growth, flowering and biochemical activities were studied out in four cowpea (Vigna unguiculata) genotypes in control environments. The results revealed that both germination and seedling growth were negatively affected by 0.02%. SA application, however did not affect the size of full expanded buds, time of 50% flowering and date of flower initiation. A maximum increase in peroxidase (EC1.11.1.7) activity was observed in UPC 4200 over other genotypes. No significant change in the content of total soluble and intercellular fluid proteins was observed except in UPC 4200 genotype. SA induced accumulation of total soluble sugars more at flowering stage than at seed setting stage. It is evident from the present study that UPC 4200 genotype was more responsive to salicylic acid both in terms of increased peroxidase activity and less negative effect on morphological attributes, thus suggesting its wider use without negative impact on environment as salicylic acid has been reported in plants.

Knowledge about heart attack and hypertension among individuals attending a cardiac camp in Pokhara city.

OBJECTIVES: Previous studies in other countries had shown lacunae in patients' and general publics' understanding of cardiovascular diseases. Such studies are lacking in Nepal. Hence the present study was carried out to: a) note the respondent's knowledge regarding myocardial infarction and hypertension and b) note the association, if any, of the knowledge with demographic and personal characteristics. MATERIALS AND METHODS: Respondents attending a cardiac camp organized in the Manipal Teaching hospital during September 2002 were interviewed by previously briefed seventh semester students using a structured questionnaire. Basic demographic information and knowledge about myocardial infarction and hypertension was collected. The median score was calculated. Differences in scores among different subgroups of respondents were noted using appropriate statistical tests (p<0.05). RESULTS: Sixty-six respondents were interviewed; 44 were male. The knowledge scores for heart attack and hypertension were 6 (maximum score 8) and 11 (maximum score 14) respectively. The scores were significantly lower among respondents with a monthly family income below 2000 rupees and was higher among respondents/family members suffering from cardiovascular disease. CONCLUSION: The respondents were aware of the basic facts regarding myocardial infarction and hypertension. However, lacunae in knowledge were noted. Further studies are required.

Prescribing patterns in the orthopaedics outpatient department in a teaching hospital in Pokhara, western Nepal.

OBJECTIVES: Information on the utilization patterns of drugs in the orthopaedics outpatient department (OPD) are lacking in hospitals in western Nepal. The present study was carried out to obtain demographic information about the respondents selected for analysis, information on the average number of drugs prescribed and the average cost of drugs per prescription. The prescriptions were critically analyzed using predetermined criteria. MATERIALS AND METHODS: The study was carried out over a four-month period (01.09.2002 to 31.12.2002) at the Manipal Teaching hospital, Pokhara, Nepal. The percentage of encounters with an injection or an antibiotic prescribed was noted. The percentage of drugs prescribed from the Essential drug list of Nepal and the mean cost of drugs per prescription was calculated. RESULTS: 1238 patients attended the orthopaedics OPD during the study period. 186 prescriptions were randomly selected for analysis. The mean number of drugs per prescription was 1.9. Low backache was the most common reason for attending the OPD. Nonsteroidal anti-inflammatory drugs (NSAIDs) were the most commonly prescribed drug group. Diclofenac and meloxicam were the most commonly prescribed drugs. Mean cost of drugs was 166.2 Nepalese rupees. Injections and antibiotics were prescribed in 16 (8.6%) and 7 (3.8%) encounters respectively. 51 prescriptions (27.4%) had various problems. Absence of diagnosis on the prescriptions and the duration of treatment were most commonly observed. CONCLUSIONS: Percentage of prescribing by generic name was low. Educational sessions for the doctors at different levels to encourage prescribing by generic names and on correct writing of prescriptions may be considered. Studies covering a larger number of patients and for a longer time period are required. A greater number of patients can be studied, seasonal variations can be overcome and drug utilization can be measured quantitatively.

Attitudes of first-year medical students towards the doctor patient relationship.

In recent years, medical schools all over the world have instituted a variety of curricula to teach communication skills, professional values and ethics to medical students. Studies on the student attitudes towards doctor-patient relationships are lacking in Nepal. The present study was carried out to obtain information on the sharing and caring dimensions of the doctor-patient relationship and note any association of the dimensions with the demographic characteristics of the respondents. The study was carried out among first year students of the Manipal College of Medical Sciences, Pokhara, Nepal in August 2003 using the patient-practitioner orientation scale. One hundred and sixty-five students participated. The mean +/- SD total, caring and sharing scores were 3.71 +/- 0.48, 3.51 +/- 0.55 and 3.91 +/- 0.62 respectively. Students whose first degree relative was a doctor had higher sharing score compared to those without doctor relatives. Female students had higher scores. Students had a positive attitude towards the doctor-patient relationship. Our scores were lower than those reported previously. Further studies are required and the results obtained will be helpful in designing a doctor-patient relationship course for Nepal.
