Abstract:Introduction: The dynamics of bacterial populations in soft tissue wounds and bone differ greatly over time. The primary goal in the management of open fracture is the prevention of the infection of the bone and soft tissue. To achieve this goal, the most widely accepted treatment protocols include early surgical debridement, irrigation of open wounds, administration of broad- spectrum antibiotics, and stabilization of fractures.In this study, we studied the pattern of bacterial isolates in all cases of open fractures of extremities that came to the local secondary \& tertiary care hospitals.
Material and Methods: This Cross Sectional analytical study involved Prior Consent from the patients \& was found to be within ethical standards. It was conducted in nine months. In the present study, 100 patients of all ages, both the sexes, with open fracture of all the grades as per Gustilo-Anderson classification, coming to Orthopaedic Outpatient Department and Emergency Dept of selected hospitals including ours were selected.
Results: Patients who were brought after 6 h showed maximum growth of bacterial isolates. Pre-debridement cultures were taken in all 100 patients, and the presence of growth of organism was found in 56% . Out of the positive 56 patients, 37 (66%) were found to have Gram-positive bacterial growth. Coagulase-negative \textit{Staphylococcus aureus} was the most common Gram- positive bacteria isolated. Gram-negative bacteria were found in 19 (34%) cases, which showed different isolates occurring in same number.Post-debridement cultures showed growth in 34% patients with no growth in rest patients [Table 2]. Out of the 34 patients, Gram-positive bacteria were isolated in 18 patients and Gram-negative in rest 50%. Coagulase-negative S. aureus was the most common.
Conclusion: Predebridement cultures are of no importance in treating open fractures. Postdebridement cultures are important in formulating an antibiotic policy to be started in patients of open fractures as soon as possible. Gram-negative organisms are the most probable cause of infection in cases of open fracture. Our antibiotic policy should cover both Gram-positive and Gram-negative organisms with two antibiotic drug regimen if possible. Aminoglycosides are the most sensitive group of drugs in both Gram- positive and Gram-negative bacteria.

Abstract:Background: Rocuronium produces faster neuromuscular blockade compared with other neuromuscular blocking drugs. It produces intubating condition similar to succinylcholine, but does not have the short duration of action. Objective: to compare the onset time of intubation and intubating condition of rocuronium with priming versus without priming.
Methods: Sixty patients of ASA physical status I and II, aged between 18-60 years, of both the sexes, grouped randomly and divided into priming group (group P) and control group (group C) of 30 subjects each. Priming group (Group P) receives 0.06mg/kg of rocuronium and control group (group C) receives normal saline. All patients received inj. Fentanyl 1mcg/kg, followed by inj. thiopentone 5mg/kg for induction. Intubating dose of rocuronium 0.54mg/kg for priming group and 0.6mg/kg for control group administered 3min after priming.
Results: The present conducted study shown that onset time of intubation was 56.4(\(\pm\)6.43) sec in priming group (group P) with 3 min priming interval, 117.6(\(\pm\)16.78) sec in non priming group (group C) with clinically acceptable intubating conditions were obtained in both groups without any adverse effects.
Conclusions: Priming with the rocuronium provide excellent intubating condition in less than 60 sec when compare to non priming group and is a safe alternative to succinylcholine.

Abstract:Introduction: Adenoviruses are DNA viruses responsible for varieties of human diseases that affect the gastrointestinal tract, respiratory tract, and eye. There are seven species of adenoviruses categorized from A to G with two subgroups. The classification correlates with clinical presentation, antigenic character, and epidemiological spread and can be identified by the genetic methods.
Aims: To study the clinico-pathological relation of adenovirus associated with respiratory infections in children.
Material and Methods: Department of Pediatrics, R.G.Kar Medical College, Kolkata.
Results: In the present study, this was performed by two steps molecular techniques. The first was by the determination of adenovirus by the use of PCR for fiber gene with common primers for adenovirus. The PCR was confirmed to be positive in 11 samples. The differences in the determination of adenovirus in respiratory infections can be attributed to the difference of the studied population.
Conclusion: The prevalence of adenovirus with respiratory tract infections mainly in pneumonia with genotypes 3 and 7 as the predominant geno types in those in children.

Abstract:Introduction: Under-five mortality rate in India has been steadily decreasing but still the contribution of malnutrition to child deaths is quite high. Despite decades of nutritional interventions, Out of 1.04 million fewer than five children mortality in India the year 2017, almost 706,000 were malnourished till date.
Aim: To estimate the proportion of infants aged 1-6 months with growth faltering and their severity, to examine the association of grades of anthropometric failure, feeding practices, background characteristics and severity of morbidity of infants aged 1-6 months with mortality.
Materials and method: The present study was a hospital-based, observational, descriptive study. This Study was conducted from 18 months at Department of Pediatric Medicine of College of Medicine and Sagore Dutta Hospital, Kolkata-700058 in West Bengal. Total 83 patients were included in this study.
Result: It was observed in present study that 4 in every 10 infant aged less than 6 months admitted in hospital were underweight including 1/10th severe underweight. In our study, 3 in every 10 infant had stunting including 1/10th severe stunting. It was observed that 5 in every 10 infant aged less than 6 months admitted with ARI in hospital were underweight including 2/10th severe underweight. In Severely wasted group, 5 (10.4%) patients had Early initiation of Breastfeeding Which was statistically significant (p=0.0090). In our study number of patients had Up to date Immunization status was[49(100)] which was statistically significant (p=0.0056). It was observed that infants aged 1-6 months with Night feeding in Severely underweight group were 5 (10.4%) infants which was statistically significant (p=0.0258).
Conclusion: Present study showed that growth faltering in early infancy was associated with morbidity and mortality.

Abstract:Background: Orthopaedic surgeries of lower limb are well suited for central neuraxial blockade. While the surgeries are done under spinal anesthesia, demand for post operative pain relief and need to reduce the use of systemic analgesics requires epidural analgesia in the post-operative period.
Objective: To evaluate and compare the duration of analgesia of 0.375% Ropivacaine and 0.25% Levobupivacaine given by epidural routes in lower limb orthopaedic surgeries in 24 hrs post operative period.
Material and Methods: In this prospective, randomized, double blinded clinical study, 60 adult patients of ASA I-II of both sexes were randomized into 2 groups(n=30). Patients received 7ml of 0.375% Ropivacaine in group R and 7ml of 0.25% Levobupivacaine in group L through epidural catheter.
Results: There was no significant difference between two groups with respect to demographic profile and ASA physical status. The mean duration (minutes) of analgesia after each epidural topup was significantly longer in group L (303.5\(\pm\)21.8) compared to group R (273.2\(\pm\)23.42) with p value 0.001. Total number of epidural topups were 5 for both the groups, rescue analgesics were needed in only 2 patients in each group. Quality of motor block was predominantly grade 0 of modified bromage scale in more than 80% patients in both the groups. Haemodynamic stability was well maintained and no adverse effects encountered in both the groups.
Conclusion: Epidural 0.25% Levobupivacaine and 0.375% Ropivacaine in their equipotent doses provided adequate post operative analgesia for lower limb orthopaedic surgeries. Levobupivacaine provided prolonged duration of analgesia compared to ropivacaine. But the total number of epidural topups, need for rescue analgesics and quality of motor block were similar for both the study drugs without any haemodynamic variations and adverse effects.

Abstract:Background: Dengue is an endemic disease in tropical and subtropical regions of the world causing severe epidemic in India and is endemic in many parts of India, especially in metropolitan cities and towns. There are evidences which states that platelet parameters may have diagnostic and prognostic value in febrile thrombocytopenia including Platelet count, Mean platelet volume (MPV), Platelet distribution width (PDW), Plateletcrit (PCT). These parameters are obtained as a part of Complete Blood Count using Automated Hematology analyzers.
Aim and Objectives: of this prospective study is 1) To evaluate the role platelet parameters in Dengue fever and also to determine the relationship of platelet parameters with platelet count and disease severity. 2) to assess the utility of platelet profile in patients with Dengue fever and understand its significance so that adverse outcomes of this rapidly spreading disease can be controlled to a greater extent.
Material and Methods: This study was conducted on 133 confirmed cases of Dengue infected patients for a period of 9 months from April 2022 to December 2022. The Platelet parameters like Platelet count, MPV, PDW and Plateletcrit were measured by using BC 300 plus Mindray Automated Hematology Analyzer on venous samples collected in K3EDTA from 133 patients and was compared with disease severity (DF/DHF/DSS) . These 133 patients were grouped into three according to platelet count (<20000, 20000-100000, >100000).
Results: Out of 133 patients, 17 patients who had platelet count <20000, the Mean MPV, PDW and PCT was 9.2 fl, 17.3 fl and 0.03% respectively, 86 patients who had platelet count between 20000-100000 the mean MPV, PDW and PCT was 12.2fl, 16.6fl and 0.1% respectively, 30 patients who had platelet count more than 1 Lakh, the mean MPV, PDW and PCT was13.7fl, 13.8 fl and 0.1% respectively which showed statistically significant difference between the groups (p value 0.003).
Conclusion: The study focuses on the importance of platelet parameters in patients with Dengue infection. Significant differences were observed in MPV, PDW and PCT in patients with dengue infection. Low platelet count, low MPV, high PDW and low PCT shows sensitivity for DF thus reflecting a predictive marker for diagnosing DF in endemic area.

Abstract:Due to the lack of effective therapies, therapeutic care such as medicines and early hemodialysis is viewed as the major kind of supportive care for paraquat poisoning. The aim of our present study was to evaluate acute kidney injury and its impact on various clinical parameters, including length of hospital stay, episodes of hemodialysis, number of ICU admissions, and mortality rates. This prospective observational study was launched after receiving approval from the Institutional Ethics Committee. All patients with acute renal injury caused by paraquat were admitted to the ward of the Department of General Medicine, VIMSAR, Burla, and included in the present study after obtaining informed written consent from each participant. The results showed that serum phosphorus and uric acid were highly significant (P < 0.001) when compared to laboratory features based on clinical outcomes, followed by alanine aminotransferase (ALP; P = 0.006), serum bicarbonate (P = 0.007), and serum potassium (P = 0.009). In conclusion, paraquat poisoning has no cure, but clinicians can monitor vital statistics and laboratory changes from diagnosis onward to understand the disease's trajectory. It is recommended that the government prohibit the widespread distribution of this pesticide and inform the public about its toxicity.

Abstract:Background and Aim: Sepsis is a commonest cause of morbidity and mortality in the newborns and probably accounts for 30 to 50 percentage of neonatal death worldwide in developing countries so the study aimed to find out the most reliable laboratory parameter in early diagnosis of neonatal sepsis in comparison with blood culture in terms of Sensitivity, Specificity, Positive predictive value, Negative predictive value.
Material and Methods: A cross sectional study was conducted in the NICU and SCNU at Institute of Child Health, Government Medical College, Kottayam to evaluate the laboratory markers like total WBC count, I-T ratio, CRP, platelet count in early diagnosis of neonatal sepsis in comparison with blood culture. After taking informed consent from parents and permission from ethical committee, neonates brought to neonatology unit were selected by purposive sampling technique. Sample size was 120. All neonates having suspected sepsis were included. All neonates included in the study were started on empirical antibiotics after drawing samples for blood cultures, total WBC count, I-T.
Results: This study was designed to find out the most reliable parameter in early diagnosis of neonatal sepsis like total count, CRP, I-T ratio and platelet count in comparison with blood culture in terms of sensitivity, specificity, PPV and NPV.A total of 120 babies were studied who satisfied the inclusion criteria and ruling out those meeting exclusion criteria. Out of 120 babies studied early onset sepsis include 52.5% and late onset of sepsis include 47.5%.
Conclusion: This study proves that CRP is a test with good sensitivity and I-T ratio with maximum specificity but least sensitivity. These can be used for diagnosis of neonatal sepsis and treatment can be initiated before the blood culture results come.

Abstract:Intrathecal bupivacaine results in a longer duration of complete anaesthetic block than ropivacaine. Fentanyl used as an adjuvant may improve the quality of spinal block of ropivacaine, while maintaining its advantage of early motor recovery. The aim of the study was to compare the efficacy and safety of intrathecal ropivacaine-fentanyl (RF) with bupivacaine-fentanyl (BF) for lower limb orthopaedic surgeries. In this Single Centered, Prospective, Randomized, Parallel group, Double-Blind study, sixty patients were randomly allocated to receive either intrathecal 15 mg of 0.5% ropivacaine with 25 mcg fentanyl (Group RF) or 15 mg of 0.5% bupivacaine with 25 mcg fentanyl (Group BF). The onset, duration, spread of sensory and motor block, hemodynamic parameters, and side effects were recorded. Data analysis was done using SPSS software and Sigma Stat 3.5 version (2012). The time to reach the highest sensory level, complete motor block, and two-segment sensory regression time were comparable between the two groups. The motor recovery to Bromage scale 1 was faster in Group RF. The hemodynamic stability was better in Group RF. However, the time duration of analgesia was prolonged in Group BF. Intrathecal RF provided satisfactory anesthesia with hemodynamic stability for lower limb orthopaedic surgeries. It provided a similar sensory but a shorter duration of motor block compared to BF, which is a desirable feature for early ambulation, voiding, and physiotherapy.

Abstract:Background: Primary angle closure glaucoma (PACG) contributes considerably to the global burden of visual impairment.
Objective: To prospectively evaluate changes in anterior chamber width after laser iridotomy in primary angle closure suspect using GONIOSCOPY and BIOMETRY.
Material and Methods: This was a prospective non-randomized interventional hospital based study. 50 eyes of 29 patients with primary angle closure suspects (PACS) requiring Laser Peripheral iridotomy were included in the study.
Results: The study showed a statistically significant change between pre PI and post PI peripheral anterior chamber depth(PACD) 1.1\(\pm\)0.4 Vs 2.70\(\pm\)0.8(P<0.05) Statistically significant change in gonioscopic grading between pre and post PI, superior (0.20\(\pm\)0.40Vs2.20\(\pm\)1.10), inferior (1.0\(\pm\)1.0Vs.2.50\(\pm\)0.90), nasal (0.3\(\pm\)0.6Vs.2.40\(\pm\)0.90), and temporal quadrant (0.4\(\pm\)0.8 Vs. 2.30\(\pm\)1.0) (P<0.05). There was an overall increase of 2 units in Shaffer angle grading in all 4 quadrants. There was a significant decrease in IOP post iridotomy (16.44\(\pm\)2.70mmHg Vs 14.18\(\pm\)2.62mmHg),(P<0.05), almost 2mmHg of fall in IOP. The study showed statistically no significant change between pre and post PI biometry values-AXL and ACD.
Conclusion: Laser iridotomy produced a significant widening of the anterior chamber angle in patients with primary angle closure suspects as studied by gonioscopy and biometry. Gonioscopy is a viable tool to assess the effect of laser iridotomy.
