ABSTRACT
Hesperidin, a bioactive flavanone glycoside prevalent in citrus fruits, with remarkable therapeutic properties stands out as a formidable defender against the debilitating reproductive toxicity associated with Cyclophosphamide (CYP) chemotherapy. This study explores the protective potential of hesperidin (HSP@100 mg/kg b.wt PO daily) against CYP-induced (@ 40 mg/kg b.wt IP once in a week) reproductive toxicity in male Wistar rats as several studies were documented on single dose toxicity of CYP. In this experiment, we chose multidosage drug effects, which are more relevant in chemotherapy. Twenty-four rats were divided into four groups: Group 1 (Control), group 2 (CYP-treated), group 3 (HSP-treated), and group 4 (CYP + HSP-treated) for 28 days. The experimental design included assessments of relative testicular weight, semen analysis, testosterone levels, oxidative stress markers, inflammatory cytokines, gross and histopathological changes, and immunohistochemical evaluation. The results revealed that the administration of CYP led to a significant reduction in testicular weight, sperm count, motility, and testosterone levels, accompanied by increased oxidative stress and inflammatory response. Hesperidin co-administration demonstrated a protective effect by restoring these parameters to near-normal levels. Histopathological analysis revealed improved testicular architecture in the group 4 compared with the group 2. Oxidative stress indices indicated that hesperidin attenuated CYP-induced damage by reducing malondialdehyde levels, enhancing superoxide dismutase activity and maintaining glutathione levels. Similarly, inflammatory cytokine analysis demonstrated anti-inflammatory effects of hesperidin by reducing tumor necrosis factor-alpha (TNF-α) and elevating interleukin-10 (IL-10) levels in the group 4. Immunohistochemical evaluation of nuclear factor-kappa B (NF-κB) revealed increased inflammation in the CYP group, while hesperidin significantly reduced NF-κB expression, suggesting its anti-inflammatory properties.
ABSTRACT
PURPOSE: The caruncle is a unique anatomical site in the human body, comprising various structures derived from the surface ectoderm and mesoderm. Caruncular lesions can range from benign to malignant and present challenges in accurate diagnosis and timely management due to their hidden nature and proximity to the lacrimal sac. This study aims to provide a comprehensive description of caruncular lesions, presenting the first Indian case series on this topic. METHODS: Ethical approval was obtained, and data collection was conducted at a tertiary care center in India. A retrospective analysis was performed on 44 patients with caruncular lesions treated between 2013 and 2020. Detailed patient histories, clinical examinations, slit lamp imaging, and excision biopsies were conducted. Histopathological examination of the specimens was carried out. RESULTS: The study included 42 cases of caruncular lesions, with a mean age of 31.09 years. The majority of cases were male (54.54%). Benign lesions accounted for 84.09% of the cases, while premalignant and malignant lesions accounted for 11.36% and 4.54%, respectively. Papilloma and nevus were the most common lesions, with 11 cases each. All caruncular lesions were successfully and completely excised without complications. Histopathological examination confirmed the accuracy of the diagnoses, with an 84.09% concordance rate between clinical assessment and pathological diagnosis. CONCLUSION: This case series reveals a predominance of benign lesions among individuals in their early thirties. The successful excision of all lesions with a high concordance rate between clinical assessment and histopathological diagnosis underscores the importance of timely and accurate management.
ABSTRACT
Introduction Cerebrovascular accidents or strokes are a major cause of mortality and morbidity in today's world. Post-stroke disabilities like paralysis, dementia, etc., can affect the quality of life of patients as well as their families. A combined increase in neutrophils and a decrease in lymphocytes during inflammation in stroke manifests as an elevated neutrophil-to-lymphocyte ratio (NLR), thereby indicating the severity of neural damage. Aim We aimed to determine if an elevated NLR observed on the day of hospital admission can predict a higher risk of in-hospital mortality in stroke patients. Confirmatory results could aid in developing risk stratification for management, ultimately improving clinical and functional outcomes. Materials and methods Sixty stroke patients were monitored throughout their hospital stay in this prospective cohort study. NLR was calculated at admission using routine complete blood counts. The data were analyzed using SPSS Software v23.0 (IBM Corp., Armonk, NY). An unpaired t-test was used to compare the means between the two groups. Categorical data were analyzed using the chi-square test. The receiver operating curve (ROC) was plotted and used to ascertain if a cut-off value of NLR could be obtained to predict in-hospital mortality in stroke patients. P values <0.05 were considered statistically significant. Results About 23.3% (n=14) of the patients died during their hospital stay, with no significant differences between the survivor and death cohorts in terms of comorbidities like diabetes and hypertension. The mean NLR calculated within 24 hours of hospital admission in patients who died (NLR=8.47 (standard deviation (SD)=4.67)) was significantly higher (p=0.009) than in those who survived (NLR=5.84 (SD=2.62)). Upon ROC analysis, patients with NLR >6.03 on the day of admission demonstrated a higher risk of in-hospital mortality (p=0.015 (95% CI: 0.577-0.855)). An area under the curve (AUC) of 0.72 with a sensitivity of 92.86% and a specificity of 54.35% was obtained. Conclusions Elevated NLR (cut-off >6.03) obtained within 24 hours of hospital admission is an indicator of a higher risk of in-hospital mortality in stroke patients. Hence, patients presenting with a high NLR at admission can be prioritized for personalized targeted treatment, potentially reducing mortality and post-stroke complications.
ABSTRACT
BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is a multidrug resistant organism recognized as major cause of infections ranging from relatively minor skin and soft tissue infections to life-threatening systemic infections. Contact transmission from health care personnel (HCP) to the patients provides the main mode of transmission of MRSA. Screening of HCPs colonized with MRSA may aid in preventing spread of this organism. METHODS: Two samples were collected from 200 HCP which included sample from anterior nares and web spaces of both hands. Identification of Staphylococcus aureus and MRSA strains were done as per standard operating protocol. Results were compiled, tabulated, and all data were subjected to SPSS, version 17.0 software for analysis. RESULTS: About 25.5% (51 HCPs) were carriers of S aureus and among them 6.5% (13 HCPs) were carriers of MRSA. Among the MRSA carriers, 28.4% were physicians, followed by nursing interns (21.1%), MBBS interns (9%), nurses (5.4%), and others, that is, physiotherapist, housekeeping staff, and helping staff (37.5%). CONCLUSIONS: In spite of having infection control policies in place, MRSA carriage rate was 6.5%. This signifies the importance of periodic systematic screening of all HCPs and decolonization, which may help in eliminating the burden of MRSA carrier status and spread of infection in the health care setting.

ABSTRACT
Typical manifestations of coronavirus disease (COVID-19) involve the upper and lower respiratory tract. But as the pandemic surges, we are encountering numerous case reports and series of extrapulmonary presentations of COVID-19 in the outpatient department. Abundant retrospective data have also cited various extrapulmonary complications in the hospitalized COVID-19 patients. This knowledge needs to be condensed and disseminated in order to improve COVID-19 surveillance and to reduce the accidental exposure of healthcare workers. Our review suggests that gastrointestinal tract, cardiovascular system, nervous system, renal system, and manifestations due to hematological abnormalities are common masqueraders to watch out for.

ABSTRACT
Every patient in neurocritical care evolves through two phases. Acute pathologies are addressed first. These include trauma, hemorrhagic or ischemic stroke, or neuroinfection. Soon after, the concentration shifts to identifying secondary pathologies like fever, seizures, and ischemia, which may exacerbate the brain injury. Frequent bedside examinations are not sufficient for timely detection and prevention of secondary brain injury (SBI) as per the International Multidisciplinary Consensus Conference on Multimodality Monitoring in Neurocritical Care. Multimodality monitoring (MMM) can help in tailoring treatment decisions to prevent such a brain injury. Multimodal neuromonitoring involves data-guided therapeutic interventions by employing various tools and data integration to understand brain physiology. Monitors provide real-time information on cerebral hemodynamics, oxygenation, metabolism, and electrophysiology. The monitors may be invasive/noninvasive and global/regional. We have reviewed such technologies in this write-up. Novel themes like bioinformatics, clinical research, and device development will also be discussed.

ABSTRACT
Chronic Otitis Media (COM) is a major cause of acquired hearing impairment especially in developing countries. Persistent perforations occur either due to improper treatment of recurrent otitis media or infected traumatic perforation. Myringoplasty, repair of the Tympanic membrane using autologous temporalis fascia, is the standard procedure for COM. Other graft materials commonly used include tragal perichondrium, tragal cartilage and adipose tissue. This prospective study aims to compare the surgical and audiological outcome of fat plug myringoplasty [FPM] and conventional myringoplasty using temporalis fascia [CM-TF] in COM with small dry central perforation. A total of 60 patients of COM with small dry central perforation, aged 16-60 years, during the study period of October 2013 to August 2015 were divided into two groups of 30 cases each. The first group underwent FPM while the second group underwent CM-TF. The graft uptake and hearing outcome [pre operative and 3 months post operative PTA] were assessed. The surgical outcome of FPM with graft uptake of 86.7% was comparable to CM-TF with a graft uptake of 90%. The mean post operative hearing gain in FPM was 3.43 ± 2.81 dB which correlated well with that of CM-TF with 3.85 ± 3.05 dB. The duration of hospital stay and operative time was significantly lower in FPM group. FPM can be safely performed in cases with dry, small central perforations of the tympanic membrane with outcomes comparable to CM-TF.
ABSTRACT
CONTEXT: The provision of initial treatment to a patient with suspected meningitis depends greatly on early recognition and rapid diagnostic evaluation of cerebrospinal fluid (CSF) leukocytes, proteins, and glucose. The diagnosis is time critical and timely intervention has an implication on the prognosis and outcome. Reasonably, sound laboratorial setups are not available in our country in the primary health-care level and, even in the settings where they are available, long waiting periods precede the availability of results. AIMS: We conducted this study to emphasize the role of urine reagent strip test as a rapid diagnostic tool in CSF analysis. SETTINGS AND DESIGN:: This is a prospective single-blinded study on 100 consecutive CSF samples received with in 1h of tap. SUBJECTS AND METHODS: All the 100 samples were subjected to definitive test being CSF microscopy and biochemical analysis of proteins and sugar and index test being a semi quantitative analysis of CSF leukocytes, proteins, and sugar by urinary reagent strips. STATISTICAL ANALYSIS USED: The diagnostic accuracy of the reagent strip for different cutoff levels was estimated and tabulated in the form of sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio. RESULTS: 77% of cases were in the pediatric age group and 23% cases were adults. The sensitivity and specificity for leukocytes by the strip method for ≥15 cells/cumm were 89.28% and 98.61%, respectively, which increased to 100% with an increase in the counts. The reagent strip test had a sensitivity of 85.71% and a specificity of 95.65% for the protein levels >30 mg/dl which increased to 100% with an increase in protein levels. The reagent strip test for glucose was highly specific (100%) but less sensitive. CONCLUSIONS: The results indicate that urine reagent strip is instrumental in bedside CSF analysis and has a future stand in the diagnosis of meningitis.

Transposition is a unique and extreme form of ectopic eruption in which a permanent tooth develops and erupts in the position which is normally occupied by other permanent teeth. Tooth transpositions are rare and they can be complete or incomplete. The aetiology of transposition is still obscure. Various populations have been studied, to determine the prevalence of tooth transpositions. 20% of the transpositions which occur on the maxillary arch involve the canine and the lateral incisor. Although they are rare, transpositions may involve the maxillary lateral and central incisors. Among all transpositions, Mandibular Lateral Incisor-Canine (Mn.I2.C) is the rarest, with a prevalence rate of 0.03%. Although various reports have been published on tooth transpositions, very few have noted the agenesis of teeth, particularly Mn.I2.C and its management. We are reporting a rare clinical case with associated hypodontia.
ABSTRACT
BACKGROUND: The dedicated devices for blood irradiation are available only at a few centers in developing countries thus the irradiation remains a service with limited availability due to prohibitive cost. OBJECTIVE: To implement a blood irradiation program at our center using linear accelerator. MATERIALS AND METHODS: The study is performed detailing the specific operational and quality assurance measures employed in providing a blood component-irradiation service at tertiary care hospital. X-rays generated from linear accelerator were used to irradiate the blood components. To facilitate and standardize the blood component irradiation, a blood irradiator box was designed and fabricated in acrylic. Using Elekta Precise Linear Accelerator, a dose of 25 Gy was delivered at the centre of the irradiation box. Standardization was done using five units of blood obtained from healthy voluntary blood donors. Each unit was divided to two parts. One aliquot was subjected to irradiation. Biochemical and hematological parameters were analyzed on various days of storage. Cost incurred was analyzed. RESULTS: Progressive increase in plasma hemoglobin, potassium and lactate dehydrogenase was noted in the irradiated units but all the parameters were within the acceptable range indicating the suitability of the product for transfusion. The irradiation process was completed in less than 30 min. Validation of the radiation dose done using TLD showed less than ± 3% variation. CONCLUSION: This study shows that that the blood component irradiation is within the scope of most of the hospitals in developing countries even in the absence of dedicated blood irradiators at affordable cost.
