    Aeromonas species and Plesiomonas shigelloides in diarrhoea in Goa.
    (1995-04-01) Verenkar, M; Naik, V; Rodrigues, S; Singh, I
    Sixty six strains (1.9%) of Aeromonas species and 7 strains (0.2%) of Plesiomonas shigelloides were isolated from 3484 stool/rectal swabs from cases of diarrhoea during the study period of four years from August 1986 to July 1990 in Goa. Although the selective medium (Ampicillin sheep blood agar) was not used for the isolation of Aeromonas, an increase in the rate of isolation of Aeromonas from 0.2% in the year 1986 to 6.0% in 1990 was observed. Stool samples from 100 controls (patients without diarrhoea) examined in the year 1989 did not yield either of the pathogens.

    Bacterial pneumonias--evaluation of various sputum culture methods.
    (1993-04-01) Verenkar, M P; Pinto, M J; Savio, R; Virginkar, N; Singh, I
    With an objective of improving diagnostic value of sputum in bacterial pneumonias, 50 uncomplicated 'community' acquired cases were studied using Gram staining of sputum along with bedside inoculation with/without dilution of the specimen. Gram staining of sputum samples collected before treatment revealed pneumococcal infection in 46% cases. The results were however inconclusive on samples sent by routine procedure involving logistic delay. Cultural analysis of sputum processed by three different techniques showed that bedside inoculation of sputum after dilution to be the most efficient technique yielding Streptococcus pneumoniae in 34% cases, Gram positive cocci in lesser number (20%), Gram negative rods (GNR) in 18% cases. Sputum samples processed bedside without dilution yielded a lower number of pneumococci and other Gram positive cocci (24% & 16% cases respectively). Routine processing of sputum, involving logistic delay yielded a high number of Gram negative rods (62%), indicating their overgrowth. Thus bedside inoculation of sputum after dilution coupled with direct Gram staining serves as a simple and yet valuable laboratory aid in the diagnosis of uncomplicated 'community' acquired bacterial pneumonias.

    Bilateral asymmetry in conduction velocity in the efferent fibres of the median nerve andits relationship to handedness.
    (1977-10-01) Singh, P I; Maini, B K; Singh, I
    The conduction velocity in the efferent fibres of the median nerve has been compared in the right and left forelimbs of 38 human subjects. Six independent estimates were made for each limb. Estimates on the right and left limb of a subject were made at the same sitting. Conduction velocity was faster on the right side in the majority of right handed subjects; and on the left side in the majority of left handed subjects. The mean conduction velocity was greater on the right side in right handed subjects (P less than 0.02).

    Comparative Analysis of Unilateral Subarachnoid block with Ankle block for elective foot surgery.
    (2016-07) Singh, AP; Singh, B; Bhardwaj; Singh, I; Kaur, P
    Background: There are many accepted anesthesia techniques for elective foot surgery ranging from general anesthesia to regional anesthesia, regional anesthesia being the preferred method. Regional anesthesia techniques employed for foot surgery includes subarachnoid block, epidural anesthesia and ankle block. Objective: The present study is aimed at providing comparative analysis of ankle block with unilateral subarachnoid block for elective foot surgeries in terms of hemodynamic safety profile and post operative analgesia. Material and Methods: Study includes prospective analysis of 80 ASA II and III patients who underwent elective foot surgery. Patients were randomly divided into two groups of 40 each, Ankle block group (AB) and Unilateral subarachnoid group (US). The parameters recorded for study includes systolic blood pressure, diastolic blood pressure, heart rate, visual analogue scale for pain severity, time of first analgesic need and the complications. Results: There were minimal blood pressure changes and heart rate variability in AB group as compared to US group when compared with basal values (p<0.05). The time for first analgesic requirement is prolonged in AB group as compared to US group. The visual analogue scale score was assessed at 2nd ,4th and 6th hours for group AB were lowered as compared to group US (p <0.05).

    Comparative study of preloading with ringer lactate v/s 6% hexa starch solutions to prevent hypotension following spinal anaesthesia in elective surgery.
    (2016-07) Singh, B; Singh, A P; Bhardwaj, A; Singh, I
    Background: Hemodynamic variations are commonly encountered following subarchnoid block and can attribute to significant mortality and morbidity. To counteract the hypotension, fluid adminstration before spinal anaesthesia is recommended (preloading). Crystalloids and colloids are recommended as preloading fluids but both have their own merits and demerits. Objective: This comparative study was done to compare the effectiveness of ringer lactate versus 6% hydroxyl ethyl starch for preventing spinal anesthesia induced hypotension. Material and Methods: In this prospective study, we compare the effectiveness of ringer lactate versus 6% hydroxy ethyl starch at 10ml/kg over a period of 20 minutes before spinal anaesthesia in preventing hypotension. After administration of spinal anaestheisa mean arterial pressure were recorded at 1, 5, 10, 15, 30, 45, 60, 90 minutes and 3 hours after spinal anaesthesia. Number of patient, recieving injection Mephentermine sulphate for persistent hypotension was also recorded. Results: We found that hydroxy ethyl starch is more effective than ringer lactate solution as a preloading fluid in prevention of hypotension following spinal anaesthesia. Conclusion: Hydroxy ethyl starch is superior to ringer lactate in preventing hypotension in patients undergoing elective lower abdominal surgeries under spinal anaesthesia but the incidence of hypotension is not completely eliminated.

    A Comparison of the Frequency and Intensity of Standardized Precipitation Index (SPI) and the Rainfall Anomaly Index (RAI) during the Meteorological Drought across Harohar-Punpun Basin (India)
    (Ms. M. B. Mondal, 2024-06) Singh, I; Mishra, AK; Suryavanshi, S; Sherring, A; Kumar, M.
    The term "drought" applies to a prolonged period when there is a water shortage because of insufficient precipitation, an excessive rate of evaporation, and excessive use of water from reservoirs and other storage, including ground water. It is a slow-onset phenomenon that can have significant social, economic, and environmental impacts. Both the frequency and severity of droughts are increasing globally due to manmade and natural factors. This study looked at how well SPIs (3, 6, 12-month time scales) and RAI (Rainfall Anomaly Index) performed at identifying drought occurrences over a period of 70 years (1951 to 2021) in India's Agro-Ecological Zones. The RAI and SPI values were computed using rainfall data from 9 meteorological stations located throughout the Harohar- Punpun Basin. According to the results, the RAI is more capable than SPIs in detecting historical records of actual occurrences. Additionally, RAI is more effective than SPIs for determining both short- and long-term droughts. Since RAI can better capture the true nature of the drought situation in the Harohar-Punpun Basin, it appears to be more responsive to drought circumstances. The primary causes of drought, according to the study, include minor variations in precipitation, willful ground water removal, changing cropping patterns, and substantial changes in land use. Regional planners and administrators will surely find use for this scientific study and integrated watershed management methods for sustainable water resource management, particularly for this region.

    Dermoid (hairy polyp) of the nasopharynx.
    (1998-05-20) Chakravarti, A; Vishwakarma, S K; Arora, V K; Singh, I
    Dermoids or hairy polyps, the most primitive forms of teratoma are rare lesions affecting the nasopharynx. They arise during early embryogenesis, being derived from only two germinal layers, ectoderm and mesoderm and are invariably benign. They usually present at or soon after birth with signs of upper aerodigestive tract obstruction. A case of hairy polyp of nasopharynx in a neonate is reported for its rarity. The etiology of teratomas, their classification in head and neck region, clinical features, and management in neonates are discussed.

    Effects of passive smoking on outcome in pregnancy.
    (2004-01-30) Goel, P; Radotra, A; Singh, I; Aggarwal, A; Dua, D
    BACKGROUND: Adverse health effects of exposure to environmental tobacco smoke (ETS) among non-smokers have been studied occasionally in developing countries. AIMS: To study the effects of exposure to ETS on outcome in pregnancy SETTINGS AND DESIGN: A cross-sectional study at a secondary level teaching hospital Material and Methods: Consecutive 576 non-smoking women delivering a singleton live baby were studied. A pre-designed structured questionnaire was used to record the details of exposure to ETS at home. The maternal and foetal variables were compared among those who were exposed to ETS vis-à-vis not exposed. Unpaired Student t-test was used for the comparison of continuous variables and Fisher's Exact test was used for categorical variables. Multiple logistic regression analysis was performed after including all variables found to have significant differences on univariate analysis. RESULTS: Of the 576 women studied 141 (24%) were exposed to ETS. In the mothers exposed to ETS, there was a significantly higher incidence of pre-term birth (24.1% vs. 16.1%; P = 0.027) and small-for-gestation babies (31.9% vs.17.2%; p<0.001) as compared to unexposed mothers. The mean birth weight of the babies born to the mothers exposed to ETS was 138 g less than that of babies in the unexposed group (2632 -/+577 g vs. 2770 -/+562 g respectively, p = 0.014). The multiple logistic regression analyses showed that ETS exposure during pregnancy was significantly associated with a higher risk of small-for-gestation babies (OR 2.10; 95% CI: 1.27-3.48). CONCLUSION: Exposure to ETS during pregnancy is associated with higher risk of having a small-for-gestation baby.
