A retrospective study on the prevalence of urinary tract infections in a tertiary care hospital in Sangareddy district of South India

Background: Urinary tract infections (UTI) affect the portion of the urinary tract including kidneys, ureters, bladder, and urethra, and are among the commonly acquired nosocomial infections. Diagnosis based on the culture and sensitivity profile of the organism is highly beneficial for appropriate antimicrobial therapy of the individual.Methods: A retrospective study of culture isolates obtained from urine samples from different departments of a tertiary care hospital was performed in the period January 2018 to March 2020 in the district of Sangareddy, Telangana, India.Results: A total 204 samples of 1886 exhibited significant growth of organisms i.e., ≥105 colony-forming units of bacteria per millilitre (CFU mL-1). The most common pathogen isolated was Escherichia coli (47.05%), followed by Klebsiella pneumoniae (15.68%), Staphylococcus aureus (10.78%), Pseudomonas aeruginosa (10.78%), Enterobacter spp. (7.84%) and, Candida albicans (7.84%). The presence of Gram-negative organisms was found to be more than Gram-positive organisms among the samples cultured. Resistance was found to be more towards Amoxicillin (57.14%), followed by oxacillin (34%), cefotaxime (23.62%), clarithromycin (12.08%), erythromycin (12.08%), azithromycin (9.34%), linezolid (3.84%) and vancomycin (2.19%).Conclusions: Increasing levels of antimicrobial resistance by uropathogens emphasize the importance of therapy based on the culture and sensitivity of the organisms. Many uropathogens exhibit multi-drugs resistance. Regular surveillance and monitoring are useful in controlling the increasing resistance.

Profile of respiratory pathogens causing acute respiratory infections in hospitalised children at Rajasthan a 4 year's study

Introduction: Various pathogens cause respiratory tract infections in children of <5 years of age causing severe morbidity and mortality. The profile of causative agents varies from place to place. Aims: The objectives of our study were to detect the profile and trends of respiratory pathogens causing acute respiratory tract infection in children using a custom multiplex real-time polymerase chain reaction (RT-PCR) and to develop a diagnostic algorithm. Materials and Methods: A total of 997 children with clinical manifestations of respiratory infections were included in the study. Their nasopharyngeal aspirate and throat swab samples were subjected to nucleic acid extraction followed by multiplex RT-PCR for eighteen viruses and six bacteria. Statistical Analysis Used: Chi-square test was employed to study the P value of different viruses and bacteria. Results: A total of 765 (76.73%) samples were found to be positive for one of the respiratory pathogens. Viruses were detected in 598 (59.98%) and bacteria in 167 (41.85%) samples, respectively. The prevalence of single and co-infections among viruses and bacteria were 77.76% and 22.24%, 81.44% and 18.56% each, respectively. Respiratory syncytial virus (RSV) A/B and Streptococcus pneumoniae were the most predominant pathogens detected in the study and were associated with lower respiratory tract infections. Conclusion: RSV and S. pneumoniae were the most common pathogens detected, higher prevalence was observed in children <1 year of age. Viruses were predominant during winter months. The study helped to prepare diagnostic algorithm which will help in reducing diagnostic costs. However, further studies are required to assess whether viruses are bystander or real pathogens and include larger panel of bacteria and viruses for diagnosis.

A Cross Sectional Study Of Hellp Syndrome In Pregnancy Complicated By Severe Pre Eclampsia In A Tertiary Care Hospital

Background and objectives Hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome is a dangerous and life threatening complication in severe preeclampsia. It remains as an important cause of maternal and perinatal morbidity and mortality globally. The objective of this study was to find out the incidence of HELLP syndrome in pregnancies complicated by severe pre eclampsia and to assess the maternal and perinatal morbidity and mortality in women with HELLPsyndrome secondary to severe pre eclampsia. Methodology A one year Cross sectional study was conducted in the labour room of KLE Academy of Higher Education and Research (KAHER), Belagavi for the period of one year from January 2016 to December 2016. Ethical clearance was obtained from the JNMC Institutional Ethics committee. The primary objective was to determine the incidence of severe pre eclampsia and HELLPsyndrome in patients of severe pre eclampsia. The secondary objective was to study the associated maternal and perinatal morbidity and mortality. Results During the study period, a total of 6236 number of deliveries were conducted in the hospital. Among them, 312 (5%) pregnant women developed severe preeclampsia and 33 women developed HELLPsyndrome(10.57%). The mean age was 25.18±3.81 years. Labour was induced in 21.21% of the women. Majority (66.67%) of the women had vaginal delivery, while the rest had caesarean section (33%) . The most common indication for LSCS was HELLP 81.82%. Majority (84.85%) of the women had complications of HELLP alone while 9.09% of the women had HELLP syndrome associated with abruption. The mean birth weight was 2.27±0.69 Kgs. All cases had live births. The requirement of NICU admission was noted in 18.18% and the most common cause of NICU admission was Meconium aspiration syndrome with fetal distress (50%). The perinatal mortality rate was 16.67%. Conclusion and interpretation HELLPsyndrome is one of the rare complications of severe pre eclampsia. This study shows 5% incidence of severe preeclampsia and incidence of HELLP syndrome in pregnancy complicated by severe preeclampsia as 10.57%. The incidence in our study is high as our hospital is a tertiary care centre that receives referral cases (high risk with poor prognosis) from North Karnataka for further management.

Physico Chemical Parameters of Naspur Lake Adilabad District (A.P).

Present paper deals with the physic-chemical parameters of Naspur lake, Manchiryal mandal, Aailabad district. The work was carried out during the period of Sep-2011 to Aug 2012.This lake was established for Irrigation, Drinking water and Fish culture purpose last two decades back. It was in the out of 7 km distance from Manchiryal town. Singareni coal mine employs are living in the Manchiryal town, day by day expanding of city population last two decades .In rainy season it’s receiving city sewage .industrial wastes, coalmine dust run off to the lake. This type of water injuries to the health of human other aquatic fauna. So there is an urgent requirement for its extent of pollution which will help us in further management of conservation. During the study period examine the physic-chemical parameters such as: atmosphere temperature, water temperature, pH, electrical conductivity, alkalinity, total hardness, TDS, Ca.Mg, chlorides, sulphates and phosphate, following stranded methods (APHA 1998). Now this lake is becoming eutrophic nature.

Intraoperative blood glucose levels in neurosurgical patients : an evaluation of two fluid regimens.

Based on the evidence that hyperglycaemia aggravates ischaemic cerebral injury, it has been suggested that blood glucose levels be kept within 200 mg/dL during intracranial neurosurgery. Hypoglycaemia, however, can be a serious problem if glucose-containing solutions are avoided during the first four hours, as suggested in some studies. In order to explore the possibility of administering glucose in moderation so that the blood glucose levels are within acceptable limits, but at the same time the risk of hyoglycaemia is eliminated, we compared two intraoperative fluid regimens. Of the 52 neurosurgical patients studied, 32 patients received alternately 500 ml of 5% dextrose in normal saline and Ringer's lactate (DNS/RL Group) and 18 patients received alternately 500 ml of Ringer's lactate and normal saline (RL/NS Group). Blood glucose concentrations were determined at the end of each unit of fluid, until the patient received 4 units of fluid. In the DNS/RL group, blood glucose values peaked with the administration of each unit of DNS and tended to return towards the baseline with the subsequent RL, but remained higher than the previous control value. In the RL/NS group, there was a progressive increase in blood glucose values throughout the study period, but the increase was not statistically significant. The blood glucose levels were significantly different between the two groups after each unit of fluid except at the end of the fourth unit. Two patients in the RL/NS group had hypoglycaemia. In conclusion, the DNS/RL regimen maintains blood glucose levels within acceptable limits while avoiding the risk of hyperglycaemia. Withholding glucose completely, lowers blood glucose levels, but carries a risk of hypoglycaemia in some patients.

Effects of photodynamic treatment on biological antioxidant systems in rats.

Effects of photodynamic treatments on inherent antioxidant metabolites and cellular defence enzymes have been investigated in rats. Wistar rats were grouped into untreated controls, light controls, hematoporphyrin derivative (Hpd) (treated with 5 and 10 mg Hpd/kg body weight and kept in dark) and sets treated with both Hpd and red light (dose 172 and 344 j/m2 ). After 2, 24, 48 and 72 hr of Hpd injection the rats sacrificed, livers quickly excised to analyze Hpd uptake, activities of enzymes like catalase, GSH-Px and antioxidants like GSH, vitamin A, vitamin E and vitamin C. The results showed that the loss of Hpd from liver as a function of post- injection time was non- linear. An increased generation of lipid radicals was observed in the groups treated with 5 mg Hpd and higher dose of light and in groups treated with 10 mg Hpd at both the doses of light. Combination of light and Hpd reduced hepatic GSH content with a concomitant reduction in GSH-Px. At higher doses of Hpd and light, there was a significant reduction in hepatic vitamin A levels. Combination of Hpd and light in all doses reduced vitamin E content in liver. The decreased biological antioxidant contents and GSH-Px may be attributed to their utilization for the scavenging of free radicals generated by Hpd and light in tissues. However, no change in catalase activity and vitamin C content in liver was noted in experimental rats. The results suggest that exposure to higher doses of Hpd with light alters oxidant stress system and TBARS content in rat.

Dermostatin A and B: chromatography, structural and configurational studies using HPLC, CCD, 13C (125 MHz) and 1H (500 MHz) NMR spectroscopy.

HPLC of crude Dermostatin indicated presence of three pairs of components. Hence, attempts were made to purify Dermostatin. Purification of crude Dermostatin has been carried out using column chromatography and counter current distribution methods. Each of these fractions were tested for activity. The major fraction which showed greater activity was taken for the preparation of Dermostatin nona-acetate. Structural characterisation of Dermostatin nona-acetate has been carried out using UV-visible spectroscopy in different solvents to obtain the characteristic spectrum of a carbonyl conjugated hexaene at room temperature. Structural and configurational studies of Dermostatin nona-acetate using 500 MHz 1H NMR and 125 MHz 13C NMR has been used in the assignment of various functional groups in Dermostatin A and B as well as to provide corroboration to the earlier structural elucidation.

Effect of increased level of CO2 exposure in a closed environment on calcium and phosphorus balance in rats.

In rats, exposed to increased ambient CO2 level (1.5%) for 30 days a 40% reduction in food intake during first 10 days was observed which subsequently improved. Similarly the body weight also declined initially, which showed progressive gain thereafter, almost reaching that of ad libitum fed control by 30th day. The lowered Ca intake consequent to reduced food consumption was followed by diminution in renal and faecal excretion of Ca. The lowered renal Ca excretion was probably unrelated to reduced Ca intake, since the pair-fed-control, not exposed to raised CO2 level, did not show any such alteration. The net result was a drastic reduction in Ca balance despite the diminution in its excretion. Though the intake and renal excretion of P were reduced in the CO2 exposed group due to a reduction in food intake, the P balance showed a cyclic pattern as in the pair-fed controls. The serum Ca after 30 days' exposure remained unchanged while the serum inorganic P showed a variation. The data indicated that hypercapnia produced hypophagia which affected growth of rats. The reduced renal excretion of Ca may not pose a risk on calcification of soft tissues, since its retention was also reduced on exposure to raised concentration of CO2.

Restoration of plantar sweat secretion in the feet of leprosy patients.

As part of the studies on nerve damage and its consequences in leprosy, the status of sweat gland function in the anaesthetic sole of the feet of leprosy patients was investigated qualitatively and semi-quantitatively, before and after surgical decompression of the posterior tibial neurovascular bundle. Sweat prints of the feet of the patients were obtained pre-operatively and postoperatively on Whatman's No. 1 filter paper. The paper was treated with one percent Ninhydrin and the intensities of the Ninhydrin positive areas were quantitated. Forty one feet of thirty six patients have been studied in this manner. Sweat print analysis of twenty normal people have also been done, and included for comparison. This operative procedure has been found to effect an improvement in the sweat gland function in the feet of more than fifty percent of leprosy patients studied so far.

Collagen sheet and its usefulness in healing of ulcers in leprosy patients.

Collagen is a natural tissue present in the body. For healing of any part collagen is essential. Collagen has been made available in the form of sheets for clinical use, by the Central Leather Research Institute, Adyar, Madras 20. It has been tried in burns and ulcers. Plantar ulcers are common in leprosy and pose a problem in healing. Therefore, collagen was tried in our Institute on 75 patients having plantar ulcers, other type of ulcers like stasis ulcers and post operative wounds. It has been found from our study that Collagen Sheet hastens the healing of wounds.

Prediction and comparison of the secondary structure of legume lectins.

Secondary structure prediction for the 4 legume lectins: Concanavalin A, soybean agglutinin, favabean lectin and lentil lectin, was done by the method of Chou and Fasman. This prediction shows that these four lectins fall into a structurally distinct class of proteins, containing high amounts of β-sheet and β-turns. There is a notable similarity in the gross structure of these proteins; all four of them contain about 40–50% of β-sheet, 35–45 % β-turn and 0–10% of α-helix. When the secondary structure of corresponding residues in each pair of these lectins was compared, there was a striking similarity in the Concanavalin A-soybean agglutinin and favabean lectin-lentil lectin pairs, and considerably less similarity in the other pairs, suggesting that these legume lectins have probably evolved in a divergent manner from a common ancestor. A comparison of the predicted potential β-turn sites also supports the hypothesis of divergent evolution in this class of lectins.
