Effect of Lead Exposure and Lifestyle Factors on Methylation Index Markers Among Pb-Exposed Workers.

S-Adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) and the ratio of SAM and SAH in Pb-exposed workers need to be assessed. In this study, we investigated the effects of Pb exposure on SAM, SAH, and methylation index (MI) in Pb-exposed workers with contemplation of lifestyle factors. Blood lead levels (BLLs), SAM, SAH, MI, and lifestyle factors were assessed in 338 male Pb-exposed workers. BLLs are estimated by ICP-OES method. SAM and SAH levels in serum were determined by ELISA method. The MI was calculated using SAM and SAH individual values. The lifestyle factors were collected using standard questionnaire. Levels of SAM and MI were significantly decreased with increased age, experience > 5 years, habits of tobacco chewing, smoking, alcohol consumption, and BLLs 10-30, 30-50, and > 50 µg/dL. Levels of SAH were significantly increased with increased age, habits of tobacco chewing and smoking, and BLLs 10-30, 30-50, and > 50 µg/dL. The association between BLLs and methylation index markers (SAM and MI) was reported as negative and significant. The association between BLLs and SAH was noted positive and significant. The influence of BLLs and lifestyle factors on SAM was noted at 12%, SAH at 35%, and MI at 27%, respectively. The highest percentage of influence was noted in SAH, followed by MI and SAM. In the workers exposed to Pb, lifestyle factors resulted in decreased SAM and MI and increased SAH levels. Adaptation of healthy lifestyle factors, personal hygiene practices, and use of PPE were suggested to minimize the reduction of methylation index markers.

Evaluating the Role of AI in Predicting the Success of Dental Implants Based on Preoperative CBCT Images: A Randomized Controlled Trial.

Background: Dental implant surgery has become a widely accepted method for replacing missing teeth. However, the success of dental implant procedures can be influenced by various factors, including the quality of preoperative planning and assessment. Cone beam computed tomography (CBCT) imaging provides valuable insights into a patient's oral anatomy, but accurately predicting implant success remains a challenge. Materials and Methods: In this randomized controlled trial (RCT), a cohort of 150 patients requiring dental implants was randomly divided into two groups: an artificial intelligence (AI)-assisted group and a traditional assessment group. Preoperative CBCT images of all patients were acquired and processed. The AI-assisted group utilized a machine learning model trained on historical data to assess implant success probability based on CBCT images, while the traditional assessment group relied on conventional methods and clinician expertise. Key parameters such as bone density, bone quality, and anatomical features were considered in the AI model. Results: After the completion of the study, the AI-assisted group demonstrated a significantly higher implant success rate, with 92% of implants successfully integrating into the bone compared to 78% in the traditional assessment group. The AI model showed an accuracy of 87% in predicting implant success, whereas traditional assessment methods achieved an accuracy of 71%. Additionally, the AI-assisted group had a lower rate of complications and required fewer postoperative interventions compared to the traditional assessment group. Conclusion: The AI-assisted approach significantly improved implant success rates and reduced complications, underscoring the importance of incorporating AI into the dental implant planning process.

Garcinol: A novel and potent inhibitor of hyaluronidase enzyme.

Extracellular matrix (ECM) contains hyaluronic acid (HA) as its integral part that is involved in numerous functional activities within the body. Degradation of HA by hyaluronidase enzyme involved in many pathophysiological conditions such as asthma, arthritis, COPD and in venom spreading during envenomation. Inhibitor of hyaluronidase enzyme has a wide range of application along with the hyaluronan-hyaluronidase system. In this present study, we have evaluated the inhibitory effect of garcinol against hyaluronidase from Hippasa partita spider venom (HPHyal), bovine testicular hyaluronidase (BTH) and human serum hyaluronidase. Garcinia indica fruit rind has been used to isolate the active component garcinol. Garcinol has been used in treatment of diverse ailments. Garcinol has exhibited anti-oxidant, anti-inflammatory, HAT inhibition and miRNA deregulator in development and progression of cancers. Experimental data have shown that garcinol completely inhibited all the three tested hyaluronidase enzymes. The inhibition was found to be non-competitive pattern with reversible type. In the docking study, garcinol with hyaluronidase enzyme has been stabilized by hydrogen bonding and hydrophobic interactions. Thus, garcinol could be a potent novel inhibitor of hyaluronidase enzyme which can be further used for pharmacotherapeutic applications.

Antimicrobial susceptibility of Viridians Group of Streptococci isolated from infective endocarditis patients from 2018 to 2023.

INTRODUCTION: Viridans Group of Streptococci (VGS) are heterogeneous alpha hemolytic Streptococci that form commensal flora in the oral cavity, upper respiratory tract, gastrointestinal tract and female genital tract and are potential pathogens that can cause serious infections like infective endocarditis and bacteremia. Penicillin or Ceftriaxone is the recommended first line agent for definitive therapy of VGS endocarditis. Alteration in penicillin binding proteins can decrease the susceptibility of VGS to penicillin and other beta-lactam agents and complicate antimicrobial therapy for serious VGS infections like Infective endocarditis. The aim of our study was to determine the antimicrobial susceptibility pattern of viridians group Streptococci isolated from blood samples of infective endocarditis patients from April 2018 to September 2023 against betalactam and other agents. MATERIAL AND METHODS: Three sets of blood cultures with 8-10 ml per bottle were collected from suspected infective endocarditis and incubated in automated blood culture system (BACTEC from BD diagnostics). The broth from positive bottles was streaked on Blood agar, Chocolate agar and MacConkey agar plates and incubated at 37°C. Alpha hemolytic Streptococci that grew after 24-48 h were further identified and antimicrobial susceptibility determined by Vitek 2 system. RESULTS: A total of 100 VGS was isolated from blood samples of Infective endocarditis patients. The species most commonly isolated in our study was S. sanguinis (25%) and S.mitis/oralis group (23%) followed by Non speciated Viridans Streptococci (17%). The lowest penicillin susceptibility ie. PEN MIC <0.12 µg/ml of 40% was observed in S. alactolyticus group, followed by S. mitis (52%) and S. gallolyticus (56%). S. mitis/oralis group showed the lowest susceptibilities to betalactam antibiotics among all speciated and non speciated VGS. CONCLUSION: Infective endocarditis carries a very high mortality and morbidity and the emergence of resistance to betalactam agents like penicillin will only narrow available therapeutic options and further challenge the treatment.

Effect of Pb-exposure and B vitamin deficiencies on δ-aminolevulinic acid dehydratase activity among workers from Pb recycling plants.

Previous studies reported that Pb exposure causes a negative association with delta-aminolevulinic acid dehydratase activity (δ-ALAD), but the impact of Pb exposure (dose and time), B vitamin deficiencies, and lifestyle factors needs to be explored. In this study, the impact of Pb exposure, B vitamin deficiencies, and lifestyle factors on δ-ALAD activity among workers exposed to Pb from the Pb-recycling process was evaluated. Blood lead levels (BLLs), B vitamins (B6, B9, and B12), hematological factors (Hb% and HCT), lifestyle factors, and δ-ALAD activity was assessed in 170 male Pb-exposed workers engaged in the Pb recycling process. BLLs are estimated using the ICP-OES method. B vitamins in serum samples from workers were determined using the ELISA method. The δ-ALAD activity in whole blood samples was determined using the spectrophotometer method. The lifestyle factors were collected using a standard questionnaire. The δ-ALAD activity was significantly decreased in workers with the habits of alcohol use, tobacco consumption, hematocrit < 41%, mild and moderate categories of anemia, vitamin B6 and B12 deficiency, and BLL categories of 10-30, 30-50, and > 50 µg/dL. Multiple regression analysis revealed that the independent variables of alcohol consumption (ß = - 0.170; P = 0.025), BLLs (ß = - 0.589; P = 0.001) and Hb% (ß = 0.183; P = 0.001) significantly influenced the δ-ALAD activity with 44.2% (R2 = 0.442). Among the workers exposed to Pb from the Pb recycling plant, δ-ALAD activity was considerably reduced by Pb exposure, B vitamin deficiency, hematological parameters, and lifestyle factors.

Comparative Evaluation of Buccal Exfoliated Cells in Individuals with Diabetes Mellitus and Healthy Controls: A Cytomorphometric Analysis.

Background: Diabetes mellitus is the third most frequent cause of mortality and morbidity worldwide. Patients with diabetes exhibit a variety of oral symptoms, and hence the early detection of this condition can be addressed by a dentist. Aim: The current study aimed to study the cytomorphometric alterations of buccal exfoliated cells in individuals with type II diabetes mellitus. Methodology: The study included thirty diabetics and thirty healthy controls. The smears were obtained from the buccal mucosa and stained with Papanicolaou stain and hematoxylin and eosin stain. The presence of inflammatory cells, microbial carriage, nuclear enlargement, and perinuclear halo and binucleation were examined on the slides. Cellular and nuclear parameters were quantitatively measured using Image J software. Statistical analysis was done using SPSS software, and the Student's t-test was employed. Results: No inflammatory cells or microbes were observed in Group I individuals; however, the perinuclear halo was observed in 16.6% and binucleated cells in 3.3% of the controls. Inflammatory cells, consisting mainly of neutrophils and lymphocytes were seen in 40%, microbial carriage in 26.6%, perinuclear halo in 73.3%, and binucleated cells in 36.6% of the diabetic patients. The mean nuclear diameter, area, and nuclear-cytoplasmic ratio were significantly high in diabetic patients when compared to healthy controls. Conclusion: Oral exfoliated mucosal cells of patients with diabetes mellitus exhibit distinct cytomorphometric alterations such as increased nuclear diameter, nuclear area, and nuclear-cytoplasmic ratio.

Comparative study of concurrent conventional chemoradiotherapy versus hypofractionated chemoradiotherapy in newly diagnosed glioblastoma multiforme postoperative patients.

Purpose: To assess the treatment response and toxicity profile among two groups of newly diagnosed glioblastoma multiforme (GBM) postoperative patients receiving conventional radiotherapy (RT) versus hypofractionated RT with concurrent temozolomide (TMZ) in both. Materials and Methods: A total of 50 patients randomly allotted into two arms (25 in each). Dose received 60 Gy (2 Gy/#) in conventional fractionation RT versus 50 Gy (2.5 Gy/#) in hypofractionated RT with concurrent TMZ 75 mg/m2 orally daily in both arms, respectively. Follow-up was done at 1, 3, 6, and 12 months after completion of treatment to evaluate toxicities, treatment response, and progression-free survival (PFS). Results: All patients were well tolerated with treatment; no major adverse effects were monitored in two arms. There was no statistical significant difference in treatment response, which was found 64% versus 60% in arm A and arm B, respectively, at 3 months of follow-up (P = 0.768). Toxicity profiles were also noted similar in both arms. The 6-month PFS was 84% and 80% in arm A and arm B, respectively (P = 0.71) and 12-month PFS was 60% and 52% in arm A and arm B, respectively (P = 0.69). Conclusion: Among the patients followed, this study showed that hypofractionated RT regimen was not inferior to conventional RT regimen.

Interfraction variations in doses at OARs during three-dimensional high dose rate brachytherapy planning of cervix cancer.

Objective: The American Brachytherapy (BT) Society recommends that BT must be included as a component of the definitive radiation therapy for cervical carcinoma because recurrences and complications are decreased when BT is used in addition to external beam radiotherapy. The aim of this study is to quantify the interfraction dose variations (VARacts) during high dose rate (HDR) BT, the effect of variation in dose in terms of excess "unrecognized" dose to OAR and to conclude the reason of the variation in reference of applicator position/geometry versus deformation of the organ at risk (OAR) concerned. Materials and Methods: Total 30 patients of carcinoma cervix, biopsy proven, between June 2018 and May 2019, were taken for the study. All patients were treated with external beam radiation therapy to a dose of 50 Gy in 25 fractions over 5 weeks, followed by three fractions of HDR intracavitary brachytherapy (ICBT) (7.5 Gy to point A in each fraction) by two-dimensional (2D) X-ray-based planning. Before treatment in the first and last fraction of BT, computed tomography (CT) scan was done for every patient. Then, a 3D-based planning was performed with CT images on our HDR Plus software with image sequence option. VARact was calculated. Rigid image registration of consecutive fraction images was used for quantification of the hypothetical variation in dose (VARhypo) arising exclusively due to changes in applicator placement and geometry. Results: The mean contoured rectal volumes for the first and third fractions were 41.49 cc and 44.72 cc, respectively, while the respective volumes for bladder were 9.33 cc and 9.35 cc cm. These differences were statistically insignificant (P value: 0.263 and 0.919 for rectum and bladder, respectively). The mean equivalent dose in 2 Gy fraction (EQD2) bladder D2cc was 5.68 Gy and 5.79 Gy in the first and third fraction ICBT, respectively. The mean EQD2 for the rectal D2cc was 11.63 Gy and 12.85 Gy in the first and third fraction ICBT, respectively. None of the patients had an actual cumulative EQD2 more than 90 Gy for bladder, but 36.66% of the patients had a rectal dose exceeding the tolerance (75 Gy). Regression plots showed that VARhypo alone could predict about 42.2% of the VARact in the rectum and 19.2% of the VARact in the bladder. Thus, the remaining variation was due to the organ deformation-related dose variations between the two fractions. Conclusions: There were no statistically significant variations in the volumes or doses of OAR between the two fractions. However, a significant proportion of patients may have a higher dose to the OAR in the third fraction in the absence of individualized planning. This increase is likely to be more detrimental where higher doses per fraction are used. Variations in OAR doses may be caused by organ deformation and/or changes in applicator placement/geometry.

CD44 Expression in Oral Lichen Planus and Related Lesions-An Immunohistochemical Study.

Background: Cluster of differentiation 44 (CD44) is a cell surface adhesion protein involved in the progression and metastasis of oral squamous cell carcinoma. The current study aims to evaluate the expression of CD44 in oral lichen planus and related lesions and thereby assess the relative risk of malignant transformation of these lesions. Materials and Methods: Formalin-fixed paraffin-embedded tissue blocks of 10 oral lichen planus (Group 1), 10 oral lichenoid lesions (Group 2), 8 with oral lichen planus with dysplasia (Group 3), and 5 with lichenoid dysplasia (Group 4) were included in the study. Immunostaining was done for the tissue sections using CD44 mouse monoclonal antibody. Staining density, staining intensity, and immunoreactive scores of CD44 were evaluated in all four groups. Statistical analysis was done by Statistical Package for the Social Sciences® software and the Kruskal-Wallis test was used. Results: CD44 staining pattern of lichenoid dysplasia and lichen planus with dysplasia changed from membranous to cytoplasmic. The membranous CD44 immunoreactivity was mild with a score of 2.25 for Group 3 and 1.6 for Group 4 whereas moderate for other groups with a P-value of 0.009. The cytoplasmic immunoreactivity was significantly high in Group 3 (5.3 ± 2.6) followed by Group 4 (3.2 ± 1.2), Group 2 (1 ± 1.8), and Group 1 (0.7 ± 1.3) with a P-value of 0.001. Conclusion: The CD44 membranous immunoreactivity scores were low while the cytoplasmic immunoreactivity was high in oral lichen planus with dysplasia and oral lichenoid dysplasia when compared to oral lichen planus and oral lichenoid lesions. CD44 immunostaining pattern can help in assessing the malignant transformation of oral lichen planus or lichenoid lesions.

Current management of appendicular mas - a narrative review.

Appendicular mass is considered as one of the complications of acute appendicitis but there is no consensus on the optimal management of this condition. The management of this condition has always been conservative management with interval appendectomy as popularized by Oschner and Sheerin. The need for interval appendectomy has now been questioned, and an emerging trend has been early appendectomy by laparoscopic method. There are no guidelines on the management of appendicular mass and treatment is decided by the surgeon. We have conducted a narrative review to investigate what is the current practice in the management of appendicular mass.

Bilateral orthodontic extractions using physics versus conventional forceps among Indian patients.

It is of interest to assess whether or not physics forceps are superior to traditional forceps for the extraction of premolar teeth in orthodontic procedures. Tooth and buccal bone fractures, as well as extraction time, lacerated gingiva, postoperative discomfort, and infection, were all measured in this research of both types of forceps extraction. Twenty individuals who need orthodontic extraction on both jaws were enrolled in the research. One arch's premolars were removed in two appointments, the first using Physics forceps and the second using conventional ones. The subsequent assignment included extraction from the obverse arch. Intraoperative evaluations included assessments of factors such as tooth and buccal bone fractures, surgical time, and gingival lacerations; postoperative assessments of pain and infection were conducted on days 1, 3, and 7. With physics forceps, the average time to remove a patient's mandible was 86.55 seconds, whereas traditional forceps required just 35.70 seconds. Using traditional forceps, the average pain score was 0.865 on day one after surgery, but with physics forceps, it was 3.30. The use of physics forceps resulted in one buccal bone fracture out of twenty premolar extractions. That so, no meaningful statistical change was seen. There was no tooth damage or post-operative infection with either set of forceps, it was found. Each forceps caused a Grade I laceration to the gingiva. The average time required removing a maxillary using physics forceps was 224.05 seconds, whereas the time required doing it with conventional forceps was 141.50 seconds. On a Visual Analogue Scale (VAS), the average first-day pain after surgery using physics forceps was 4.90, whereas using traditional forceps resulted in just 3.15. The difference between using physics forceps and regular forceps was statistically significant by the third postoperative day (2.05 vs 0.75). There was a statistically insignificant increase in the occurrence of buccal bone fracture and tooth fracture while using physics forceps. Both forceps and scissors caused just grade I lacerations, and there was no postoperative infection. These findings suggest that the use of physics forceps, as opposed to conventional forceps, may significantly lengthen the time required to remove orthodontic premolars on both sides of the mouth. Non-significant results were also found for additional criteria such as buccal bone fracture, tooth fracture, gingival laceration, and post-operative discomfort. When it comes to orthodontic premolar extraction, this research found that traditional forceps performed better than modern forceps across a range of measures, including intraoperative time and postoperative discomfort.

A plan comparison study between rapid arc and conventional intensity-modulated radiation treatment plans in nasopharyngeal carcinoma patients.

Introduction: Head and neck cancers are one of the common malignancies in Indian population. It's entity, nasopharyngeal carcinoma is among the aggressive malignancies with its location and spread near very critical structures. Thus requires a highly conformal radiotherapy delivery techniques. Purpose: The aim of the study is to dosimetrically evaluate and to compare Intensity modulated radiation therapy (IMRT) plans and RAPID ARC plans for irradiation of nasopharyngeal carcinoma. Material and Method: A retrospective study is done on 10 nasopharyngeal carcinoma patients, who were treated with Radiotherapy at ATRCTRI Bikaner. Radiotherapy was delivered by IMRT technique (Total of 70 Gy in 33 fractions). Same patients are now planned on Rapid arc technique. Dosimetric comparison is done in terms of PTV coverage, OAR dose, conformity index, homogeneity index. Result: PTV coverage is similar with both the plans. Homogeneity index is higher for IMRT plans 0.119+/- 0.020 compared to 0.104 +/- 0.018 for Rapid arc plans (statistically significant).The Rapid arc plans achieved slightly better conformity 1.018+/-0.09, whereas 1.105+/-0.12 for IMRT plans. Rapid arc achieved better results for OAR, statistically significant for Brainstem (54.4 +/-10.4 Gy for IMRT and 49.7+/-4.2 Gy for Rapid Arc, Lens (Left lens and Right lens received 10.55+/-5.8 Gy and 9.44+/-9.08 by IMRT and 6.12+/-6.1 Gy and 5.45+/-6.05 Gy for Rapid Arc), optic nerves (Right and Left optic nerve received 34.36 and 35.01 Gy for IMRT plans and 30.06 and 30.05 Gy for Rapid Arc plans. However the gains are statistically insignificant for spinal cord and vestibulocochlear nerve. No major difference found for Right and left parotid between both the arms. Conclusions: Rapid Arc is better technique compared to IMRT for Nasopharyngeal carcinoma treatment, that provides better dose conformity, more homogeneous coverage and OAR sparing. However study is retrospective and has lesser patients, thus requires prospective study with more number of patients along with comparison of clinical outcome.

Non-alcoholic Fatty Liver Disease in Overt Hypothyroidism: A Cross-Sectional Study in a Tertiary Care Hospital.

BACKGROUND:  The term non-alcoholic fatty liver disease (NAFLD) describes a condition in which excess fat accumulates in the liver, similar to alcohol-induced liver injury but affecting those who don't consume alcohol. Liver steatosis may vary from simple hepatic steatosis to more serious conditions, including non-alcoholic steatohepatitis and cirrhosis, and is linked to an increased risk of hepatocellular carcinoma (HCC). There is an estimated 20-30% prevalence of non-alcoholic fatty liver disease over the globe. The incidence rate among Indians is 26.9%. Metabolic diseases like insulin resistance, obesity, type-2 diabetes mellitus, and dyslipidemia are risk factors for NAFLD. A correlation between overt hypothyroidism and NAFLD has been discussed. OBJECTIVES:  To determine the magnitude of non-alcoholic fatty liver disease in overt hypothyroidism and to estimate the clinical and biochemical profile of patients with overt hypothyroidism and its relationship. METHODS: Throughout the course of a year, researchers from the medical department of a large hospital in southern India collected data in a cross-sectional observational study. Thyroid profile, fasting lipid profile, liver function tests, and ultrasound of the abdomen and pelvis were administered to a total of 100 male and female patients (18-60 years old) with newly diagnosed overt hypothyroidism who were visiting the outpatient department (OPD) and hospitalized in wards of general medicine. RESULTS: About 75% of subjects were females, with a mean age of 37.63±7.6 years and a mean body mass index (BMI) of 25.07±1.5 kg/m2. A significant correlation was found between dyslipidemia and thyroid-stimulating hormone (TSH) levels (p-value <0.001), and between dyslipidemia and ultrasonogram (USG) finding of NAFLD (p-value <0.001). A significant correlation was seen between TSH values and NAFLD findings (p-value <0.001). CONCLUSION: NAFLD is a risk factor for developing hepatocellular carcinoma and is a known contributor to cryptogenic cirrhosis. Hypothyroidism is being studied as one of the causes of NAFLD. When hypothyroidism is diagnosed and treated early, it may reduce the likelihood of NAFLD and associated consequences.

Oesophageal carcinosarcoma: a rare neoplasm of the oesophagus.

Oesophageal carcinosarcoma (OCS) is a rare oesophageal cancer, expressing both carcinomatous and sarcomatous elements. Although believed to have a better prognosis, no standard guidelines exist for its diagnosis and management. We report a case of a 60-year male presenting with progressive dysphagia and weight loss. Endoscopy and contrast-enhanced computed tomography of the chest revealed a large polypoidal intraluminal growth at the mid-oesophagus. Endoscopic biopsy revealed a sarcoma of the oesophagus. The patient underwent McKeown minimally invasive oesophagectomy. Final histopathology was suggestive of OCS. Postoperatively, the patient received adjuvant chemoradiation. At 20-month follow-up, he was asymptomatic with no radiological evidence of recurrence.

Synthesis and antiproliferative activities of novel piscidinol a derivatives as potential anticancer agents.

Piscidinol A (1), a major compound isolated from Aphanamixis polystachya, showed modest anticancer activity against cancer cell lines. Subsequently, a series of analogues were synthesised by modification of the key structural functionalities of this high yield natural product and assessed for their anticancer potential against various cancer cell lines. Among the tested derivatives, the compounds 6e and 6i are significantly reduced the cell viability at 5.38 and 5.02 µM against DU145 prostate cancer cells, respectively. Additionally, both the compounds arrested the cell cycle at S phase and induced the late apoptosis in DU145 cells. Together, the results demonstrated that the compounds 6e and 6i could be a promising lead for the development of anticancer agents against DU145 and well worth further investigation aiming to generate potential anticancer agents.

Differential expression of inflammatory cytokines, prostaglandin synthases and secretory leukocyte protease inhibitor in the endometrium and circulation in different graded CEH-pyometra in bitch.

Cystic endometrial hyperplasia (CEH)-pyometra (CEH-P) is one of the most common reproductive disorders in bitches, posing a risk to both future fertility and life. The aims of the current study were to elucidate the differential expression patterns of inflammatory mediators at transcript and protein levels in the endometrium and to assess the concentrations of key inflammatory mediators in the peripheral circulation of bitches with different graded CEH-P. A total of 25 client-owned intact mixed breed bitches of 3-10 years presented to the outpatient department of RVP-TVCC of the institute were considered for the study. Of which, 22 cases suggestive of pyometra and 3 cases of CEH obtained during routine elective ovariohysterectomy were subjected to histopathological examination. Uteri were categorized into CEH (n = 3), moderate CEH-P (mCEH-P, n = 9), severe CEH-P (sCEH-P, n = 6) and atrophic pyometra (AT-P, n = 7). A group of age matched (n = 12) bitches without pyometra served as control. Endometrial transcripts such as IL6, IL8, PTGS2, PGFS, and SLPI were expressed differentially in the CEH and CEH-P bitch. In addition, a strong immunoreactivity (IR) of IL6, IL8, PTGS2, and mPGES1 was recorded in the sCEH-P uterus, while expression of IL10 was noticed in AT-P. In circulation, serum IL6 was the most relevant marker with high sensitivity of 96.2% and specificity of 84.6% at a cut off concentration 8.5 pg/mL followed by SLPI with 95.2% sensitivity, and 84.6% specificity at cut off concentration of 1.3 ng/mL. Serum IL10, PGFM and SLPI concentration in the peripheral circulation were 1.5-2.23 fold higher in mCEH-P, 0.87-2.5 fold higher in sCEH-P and 2.9-3.5 fold higher in AT-P than that of control. It is concluded that monitoring the serum concentration of IL6, IL10 and SLPI would be useful adjunct to the established hematobiochemical parameters in the management of pyometra in the bitch with critical illness.

Survival pattern in cervical cancer patients in North West India: A tertiary care center study.

Background: Cervical cancer is most common malignancy of female reproductive system worldwide. As per GLOBOCAN 2020, there are 604,127 (6.5%) new cases of cervical cancer in the world, among women it is fourth most common and eighth most common in both sexes. In India,there are 123,907 total new cervical cancer cases (18.3% in female sex whereas 9.4% in both sexes). There are several etiological factors and the most significant is due to persistent infection of specific human papilloma virus (HPV) strains,particularly type 16 and 18 which are most common. Screening and early detection is likely to improve mortality and incidence also. Aims and Objectives: The objective of this retrospective study was to determine the survival rates of cervical cancer and its associated factors in North-West region. Materials and Methods: A total of 520 newly diagnosed cases of cervical cancer were enrolled at Acharya Tulsi Regional Cancer Treatment and Research Centre, Bikaner from January 1, 2014 to December 31, 2014 were included in this study. The main source of information was patient's medical records from which the data were abstracted and cases were followed up for next five years periodically from the date of diagnosis to access their survival status. Results: Kaplan Meier analyses were conducted to identify overall survival and median survival time. Among 520 cases, 130 (25%) had lost to follow up so excluded from the study and the study sample was about 390 patients. The median survival time for cervical cancer in this study was 60 (32-60) months and the overall survival rates at 1, 3 and 5 years were 93.07%, 72.3% and 54.9% respectively. Education, use of oral contraceptive pills (OCP), tobacco chewing ( good survival in tobacco non-chewers) and staging were significantly associated with survival. Conclusion: The 1, 3 and 5 year survival rates for cervical cancer were found to be 93.07%, 72.3% and 54.9% respectively. Various factors determining survival rates were potentially modifiable. Early diagnosis and prevention strategies are keys to obtain better outcomes.

Role of maintenance paclitaxel in epithelial ovarian cancer: An affordable option for poor resources countries (a Regional Cancer Institute study).

Purpose: The purpose of the study is to assess the benefits of maintenance chemotherapy (CT) in epithelial ovarian cancer with CT and surgery. The primary and secondary endpoints of the study were progression-free survival (PFS) and overall survival (OS), respectively. Patients and Methods: Three hundred patients with ovarian cancer (registered between January 2012 and December 2013) received 6 cycles of 3 weekly CT (injection paclitaxel 175 mg/m2 + injection carboplatin 6 AUC) and surgery. After 4 weeks of completion of the above treatment, patients were assessed for response with radiological imaging and serum CA125. Then, these patients were randomly allotted in two arms; 150 patients in Arm A received 6 cycles of single agent, 3 weekly injection paclitaxel 175 mg/m2 as maintenance therapy while 150 patients in Arm B, were on observation. The follow-up was done at 1 month, then 3 monthly in the 1st year and 6 monthly in the 2nd year to evaluate PFS and annually up to 5 years for OS. Results: The PFS at 1 and 2 years was 91% and 80% in study arm and 65% and 50% in control arm; the differences were statistically significant (P = 0.010). The 5-year overall survival was 43% versus 38% in study and control arms, respectively (P = 0.410) and 5-year PFS was 28% versus 18% (P = 0.039) in maintenance and observation arm, respectively. Except for peripheral neuropathy, there was no statistically significant difference in toxicities between the two arms. Conclusion: The study suggests that 6 cycles of single-agent paclitaxel maintenance therapy significantly prolongs the duration of PFS and better trends toward OS, though a large study is needed to come to a conclusion.

The Role of Prp in Third Molar Extraction Wounds: A Clinical Study.

It has become more common that after a mandibular third molar impaction operation, platelet concentrates have been shown to be useful in aiding the healing process. The patients were examined on day 1, day 2, day 3, day 7, the first month, and the second month following surgery. There was a slew of parameters to investigate and tally up. Materials and Methods: A total of 15 people with impacted mandibular third molars were included in the research. Patients' own blood platelets were used to make the transfusion more effective. One of the sockets was selected at random to serve as the test side. Instead of the other connector, the control socket was utilized. Results: There was no statistical difference between the test and control groups when it came to pain or soft tissue healing, according to a Mann-Whitney U test used to analyze the data. T test was performed to check for edema and density in the bones. Bone density measurements on the test side were significant, whereas measurements of edema on the test side were not. There was no alveolar osteitis on any of the subjects' limbs. Conclusion: Bone and soft tissue healing may be aided by platelet-rich plasma (PRP). Several growth components are included, which aid in the healing process.

Clinical impact of extended field radiation therapy in Stage III carcinoma cervix versus conventional field techniques: A comparative study.

Aim: The aim of the study was to examine tumor control and clinical outcomes of extended field irradiation and compare it with those treated with conventional field in same disease profile and also to determine toxicities associated with radiation treatment. Methods: This study included 50 biopsy-proven and registered International Federation of Gynecology and Obstetrics Stage III cases of carcinoma cervix treated with concurrent computed tomography (injection cisplatin 40 mg/m2 weekly) + external beam radiotherapy (EBRT) upto 50 Gy + high-dose-rate intracavitary brachytherapy (ICBT) (22.5 Gy). Twenty-five patients were randomized to each arm. Arm A: Conventional field EBRT 50 Gy with concurrent weekly chemotherapy followed by ICBT. Arm B: Extended field EBRT 50 Gy with concurrent weekly chemotherapy followed by ICBT. Results: At 12-month follow-up, 43 patients (86%) had attained CR. Overall, seven patients (14%) were in noncomplete response (CR) group (non-CR = patients with partial response, stable disease, or progressive disease). The non-CR rate was 16% for Arm A and 20% for Arm B. Among seven patients of non-CR group, six had local disease and one had failure at distant site. Five (10%) patients died in this study, 2 (8%) in Arm A and 3 (12%) patients in Arm B. Residual disease was seen in 2 (4%) patients. Grade III diarrhea was seen in eight patients (16%), 3 in Arm A (12%) and 5 in Arm B (20%). Fifteen patients (30%) developed Grade III skin toxicity. Seven patients in Arm A (28%) and 8 patients (32%) in Arm B developed Grade III toxicity. Twenty-five (50%) cases presented with varying stages of vaginal adhesions and stenosis. Conclusion: Majority of patients achieved CR with minimal acute and late toxicities with similar results in both arms. No patient had pelvic or para-aortic metastasis until recent follow-up.
