Ultrasound guided costoclavicular block in pediatric population: A prospective observational study.

BACKGROUND: The costoclavicular space serves as an alternative approach to the infraclavicular brachial plexus block, and numerous studies in adults have demonstrated promising outcomes for distal upper limb surgery. Blocking the brachial plexus at this level is potentially advantageous because the cords are relatively superficial, located in close proximity to each other and easily identified using ultrasound. AIMS: This study aimed to assess the success rate and feasibility of costoclavicular block in children undergoing unilateral below elbow upper limb surgery. METHODS: Thirty children aged 2-12 years scheduled for unilateral below elbow surgery under general anesthesia were included. Costoclavicular block was performed under ultrasound and nerve stimulator guidance with 0.5% ropivacaine, 0.5 mL/kg. Success was evaluated based on the absence of significant hemodynamic response to skin incision made 20 min after the block. The sono-anatomy of costoclavicular space, ease of needling, complications, and the post-operative pain scores were assessed. RESULTS: The mean age and weight of the children were 6.5 ± 3.8 years and 19.7 ± 9.1 kg, respectively. The success rate of costoclavicular block in our cohort is 100%. Sonographic visualization was graded as excellent (Likert Scale 2) in 90% of cases. The plexus was located at a depth of 1.4 ± 0.3 cm from the skin, the lateral extent of cords from the artery was 0.8 ± 0.4 cm and they were observed inferior and lateral to the artery. The mean needling time was 3.6 ± 1.1 min. None of the children experienced complications such as vascular or pleural puncture, hematoma, Horner's syndrome or diaphragmatic palsy. Postoperative pain scores were low, and no rescue analgesia was required. CONCLUSIONS: In conclusion, the costoclavicular block exhibited a notably high success rate in pediatric population. This study substantiates that the three cords of the brachial plexus are consistently visible and superficial during ultrasound examination using this approach, confirming their separation from vascular structures and the reliable achievement of blockade without observed complications.

Development and Testing of the Novel Sugar Meter for Informing Sugar Intake Guidelines to Parents of Three- to Six-Year-Old Children: A Cross-Sectional Study.

INTRODUCTION: In recent years, the consumption of refined sugar has increased manifold. Added sugar is implicated in dental caries, cardiovascular risk and obesity amongst other conditions. The 1025 World Health Organization (WHO) Sugar Guidelines recommends sugar intake below 10% of energy, but there is limited awareness about the same in the general population. The aim of this study was to test the Novel Sugar Meter for informing the WHO Sugar Guidelines to the parents of three- to six-year-old children. METHODS: Twenty consenting parents and their three- to six-year-old children from an English-medium school in Navi Mumbai, India, were selected. The parents were asked to record their child's baseline dietary data for three consecutive days including one weekend day. The Novel Sugar Meter, an indigenously developed ready reckoner for identifying the quantity of sugars consumed, was used. The parents were counselled using the Novel Sugar Meter (intervention) and standard instructions on the WHO guidelines (control). The dietary data were recorded again to assess and compare dietary behaviour modifications. RESULTS: Comparison of pre-intervention versus post-intervention sugar consumptions showed a statistically significant reduction in the Novel Sugar Meter group (t(10) = 3.70891; p = .001388) but not in the control group (t(10) = 0.94081, p = 0.35926). Both groups showed a reduction in the frequency of daily sugar exposure, with significantly more reduction in the Novel Sugar Meter group (p = .000049). CONCLUSION: Novel Sugar Meter-based counselling has the potential for application for reducing the quantity and frequency of sugar consumption in children.

Safety and Efficacy of Percutaneous Liver Microwave Ablation Using a Fully Water-Cooled Choke Ring Antenna: First Multicenter Clinical Report.

INTRODUCTION: The safety and efficacy of a microwave ablation (MWA) system for the liver with novel technologies in field control, antenna cooling through the inner part of the choke ring, and dual temperature monitoring were evaluated in this multicenter retrospective study. MATERIAL AND METHODS: Ablation characteristics and efficacy were assessed on follow-up imaging (computed tomography or magnetic resonance imaging). Safety was evaluated according to CTCAE classification. RESULTS: Eighty-seven liver tumors (65 metastases and 22 hepatocellular carcinomas) measuring 17.8 ± 7.9 mm were treated in 68 patients. Ablation zones measured 35.6 ± 11 mm in longest diameter. The coefficients of variation of the longest and shortest ablation diameters were 30.1% and 26.4%, respectively. The mean sphericity index of the ablation zone was 0.78 ± 0.14. Seventy-one ablations (82%) had a sphericity index above 0.66. At 1 month, all tumors demonstrated complete ablation with margins of 0-5 mm, 5-10 mm, and greater than 10 mm achieved in 22%, 46%, and 31% of tumors, respectively. After a median follow-up of 10 months, local tumor control was achieved in 84.7% of treated tumors after a single ablation and in 86% after one patient received a second ablation. One grade 3 complication (stress ulcer) occurred, but was unrelated to the procedure. Ablation zone size and geometry in this clinical study were in accordance with previously reported in vivo preclinical findings. CONCLUSION: Promising results were reported for this MWA device. The high spherical index, reproducibility, and predictability of the resulting treatment zones translated to a high percentage of adequate safety margins, providing good local control rate.

ECC Status, CRAFT Categorization and OHRQoL Assessment in 3-6-year-old Children: A Cross-sectional Study.

Introduction: Early Childhood Caries (ECC) can affect the health and quality of life of the children. Assessing a patient's risk of developing caries is an important aspect of caries management; however, can assessing the caries risk predict the impact of ECC on the OHRQoL? Few Indian studies have reported association between caries status, risk, and the impact on OHRQoL. Aim: To assess the association between dental caries status, risk assessment, and OHRQoL in 3-6-year-old children. Methodology: A total of 50 healthy children were recruited in a cross-sectional study. Parents filled the ECOHIS questionnaire. Caries status, risk, and OHRQoL were measured as dmft-pufa, CRAFT (Caries Risk Assessment for Treatment- an indigenous tool) and ECOHIS scores, respectively. Results: Moderate correlation was seen between dmft and ECOHIS scores (r = 0.496, p < 0.01), and pufa and ECOHIS scores (r = 0.408, p < 0.05). More number of subjects with higher scores of ECOHIS were in the high-risk category of CRAFT (p < 0.05). Conclusion: Caries status, risk and OHRQoL were associated in 3-6-year-old children. Thus, caries risk assessment may predict poor OHRQoL. How to cite this article: Iyer CR, Jawdekar AM.

The Effect of Motivational Interviewing on Reduction of New Carious Lesions in Children with Early Childhood Caries: A Systematic Review and Meta-analysis.

Background: Preventive therapies rely on effective behavior change. Motivational interviewing (MI), has been the most recent advancement in behavior therapies that have been successful in tobacco cessation. The effectiveness of MI needs to be evaluated in caries prevention. Objectives: To evaluate the effectiveness of MI on the reduction of new carious lesions in children with early childhood caries (ECC). Materials and methods: The two authors independently searched data from Cochrane Library, PubMed, Google Scholar, J gate, and Quintpub. Selection criteria-interventional studies written in the English language with MI as an intervention, a mean follow-up period of atleast 2 years, ECC with decayed, missing, and filled primary teeth/decayed, missing, and filled primary surfaces (dmft/dmfs) as the outcome measures, in the age group of 0-6 years. We excluded cross-sectional studies. Information regarding methods, participants, interventions, outcome measures, and results were extracted. A risk of bias assessment within and across studies was conducted. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria were applied to generate quality evidence. Results: Six studies with a total of 2,663 participants were included in the review, and meta-analysis was conducted on 4; 3 studies had a high risk of bias. A mean reduction of 2.16 (-5.06, 0.75) was observed with MI as an intervention. A sensitivity analysis revealed a mean reduction of 3.64 (-5.77, -1.51) in favor of MI. Conclusion: There is some evidence with moderate certainty that MI is beneficial in the reduction of new carious lesions in children with ECC.

A Comparison of Innovative App-Based Prescriptions With Conventional Prescriptions for Children by General Dentists: A Mixed Methods Study.

Introduction Writing drug prescriptions for children with accurate drug dosages and clear instructions is a must for general dentists. A digital tool in the form of a software application (app) to write, save and share prescriptions can potentially overcome the possible limitations of handwritten prescriptions such as handwriting illegibility, errors in calculations, and incomplete descriptions. However, it is also important to assess the satisfaction of dentists with making prescriptions using a digital tool such as an android application. A mixed methods study comparing an innovative "app-based" and handwritten prescriptions in dental settings is presented. Methodology An indigenously developed and piloted app "PREscribing children made EASY (PREASY)" was used in this study. Based on the preliminary study, a sample size of 20 was found to be adequate. Twenty-two dentists participated in the study. The conventional handwritten and an Android app PREASY-based prescriptions were compared in terms of the time taken, precision of writing, and satisfaction of the dentists. Qualitative feedback regarding the PREASY app was obtained in Google Forms (Google, Inc., Mountain View, CA, USA). Results A study sample of 20 subjects was calculated based on a pilot study, and 22 dentists were recruited. The mean time taken in seconds for handwritten prescriptions (199.14 (+ 59.18)) was almost four times higher than that for app-based prescriptions (52.05 (+ 23.89)) (t-test, P < 0.00001). The accuracy of handwritten prescriptions versus app-based prescriptions was compared by two examiners independently using analysis of variance (ANOVA) in three domains: dosage accuracy, legible handwriting, and completeness of instructions, the differences (Domain 1 mean + SD: 1.04 + 0.89, Domain 2 mean + SD: 1.38 + 0.40, Domain 3 mean + SD: 0.88 + 0.58) being statistically significant (P < 0.05). The differences in the percentages of the three domains (dosage accuracy: 40.9%, legibility of handwriting: 63.6%, completeness of instructions: 18.1%) were found to be statistically significant (P < 0.05; chi-squared statistic, 9.4017). Of the participants, 59% were very satisfied, 36.3% were satisfied, and 4.5% were neutral (chi-squared test, P < 0.00001). Participants' feedback/comments were categorized under technical suggestions, dosage suggestions, criticism, and positive remarks and were thematically analyzed. Conclusion App-based prescriptions proved to be more instantaneous and detailed than handwritten ones with the majority of dentists satisfied. Valuable feedback pertaining to the limitations of the tool was obtained for improving the app. PREASY-based prescriptions could be recommended for prescribing to pediatric dental patients.

Effect of immunoglobulin Y formulations on oral microorganisms in human subjects - A systematic review and meta-analysis of clinical trials.

Background: Passive immunization using egg yolk-based antibodies has been tested against oral microorganisms. Our study assessed the effect of immunoglobulin Y (IgY) formulations on Streptococcus mutans, Porphyromonas gingivalis, and Candida albicans in human subjects. Highlights: VS and UT independently searched articles using keyword combinations in four search engines; studies in English were selected. Either parallel-arm or split-mouth randomized controlled trials on healthy human subjects were considered. Ten studies remained in the selection; six studies compared the effect of IgY formulations on S. mutans, three on P. gingivalis, and one on C. albicans. Five studies (422 subjects) compared the effect of IgY formulations on S. mutans. When fixed-effect model (FEM) was applied, the risk ratio (RR) (confidence interval [CI]) was found to be 7.81 (6.00, 10.18). Three studies (167 subjects) compared the effect of IgY formulations on P. gingivalis. When FEM was applied, the RR (CI) was found to be 0.06 (-0.03, 0.15) in relation to reduction in probing depth. When FEM was applied, for percentage reduction in bleeding on probing (BOP), the RR (CI) was 1.99 (1.64, 2.41). Only one study (26 subjects) was available of IgY formulation and C. albicans; hence meta-analysis was not performed.The search was extended using Google Scholar, Semantic Scholar, cross-references and by contacting authors and researchers in the field which further yielded five articles. . Conclusions: IgY formulations were effective in the reduction of S. mutans. They were not effective on P. gingivalis in relation to probing depth but were effective in relation to reduction in BOP. No harms were reported. Evidence is of low quality due to high heterogeneity. The ROB was moderate and publication bias was low.

Impact of Textbook Oncologic Outcome Attainment on Survival After Gastrectomy: A Review of the National Cancer Database.

BACKGROUND: Textbook oncologic outcome (TOO) is a composite outcome measure realized when all desired short-term quality metrics are met after an oncologic operation. This study examined the incidence and impact of achieving a TOO among patients undergoing resection of gastric adenocarcinoma. METHODS: The 2004-2016 National Cancer Database was queried for patients who underwent curative gastrectomy. Textbook oncologic outcome was defined as having met five metrics: R0 resection, American Joint Committee on Cancer-compliant lymph node evaluation (n ≥ 15), no prolonged hospital stay (< 75th percentile by year), no 30-day readmission, and receipt of guideline-accordant systemic therapy. RESULTS: Of 34,688 patients identified, 8249 (23.8 %) achieved TOO. The patients for whom TOO was achieved were more likely to have traveled farther (p < 0.001) and received care in an academic (p < 0.001) or very high case-volume facility (p < 0.001). The TOO group had a significanty higher median overall survival (OS) than the non-TOO group (80.5 vs 35.3 months; p < 0.001). The Kaplan-Meier curve showed that at 12 months, the survival probability estimate was 92 % for the TOO group versus 77 % for the non-TOO group. At 60 months (long-term survival), survival probability estimates remained higher for the TOO group (57 % vs 38 %). The results of the multivariate Cox regression model found that TOO attainment was significantly associated with a reduced risk of death (hazard ratio, 0.82; p < 0.001). CONCLUSION: The TOO measure is associated with improved OS and reduced risk of death after gastrectomy for gastric adenocarcinoma. Unfortunately, in this study, TOO was obtained in only 23.8 % of cases.

Stent Graft Outcomes in Dialysis Circuits: A Review of Clinical Trials and Literature.

End-stage renal disease is a prevalent medical condition causing significant problems as the majority of patients are being treated with dialysis. While dialysis provides a means to compensate for the renal impairment, arteriovenous grafts and fistulas are often complicated by neointimal hyperplasia, loss of primary patency, and graft failure. Over the last decade, stent grafts have emerged as an alternative to balloon angioplasty and bare metal stents for revascularization in the event of arteriovenous graft occlusion or stenosis. Several randomized controlled trials have investigated the efficacy of stent grafts compared with balloon angioplasty for improving the function and durability of dialysis circuits. In this review, we present a comprehensive review of clinical trials. Stent grafts appear to offer increased primary patency over balloon angioplasty in the treatment of dialysis circuit stenosis. However, there is generally no significant difference between the two treatment modalities on other clinically relevant measures like complication rates and overall survival.

Assessment of oral health-related quality of life (OHRQoL) in children with molar incisor hypomineralization (MIH) - A systematic review and meta-analysis of observational studies.

Background: Molar Incisor Hypomineralization (MIH) affects about 14% of the population. MIH may lead to enamel breakdown, early tooth decay and is known to cause sensitivity, pain, discomfort, etc., Despite several studies reporting impacts of MIH on oral health-related quality of life (OHRQoL) in children; no systematic review has been reported till date. Objectives: Our study aimed at assessing the impact of MIH on OHRQoL. Search Methods: Two researchers, Ashwin Muralidhar Jawdekar and Shamika Ramchandra Kamath, independently searched articles using appropriate keyword combinations in three search engines - PubMed, Cochrane Library, and Google Scholar and conflicts, if any were resolved by Swati Jagannath Kale. Studies either reported in English or complete translations available in English were selected. Selection Criteria: Observational studies on otherwise healthy 6-18-year-old children were considered. Interventional studies were included only to collect the baseline (observational) data. Data Collection and Analysis: From 52 studies, a total of 13 studies could be included in the systematic review and 8 in meta-analysis. Total scores of OHRQoL measures reported in the child perceptions questionnaire (CPQ) 8-10, CPQ 11-14, and parental-caregiver perception questionnaire (P-CPQ) scales were used as variables. Main Results: Five studies (2112 subjects) showed an impact on OHRQoL (CPQ); the pooled risk ratio (RR) confidence interval (CI) were 24.70 (13.93-35.47), showing statistically significant value (P < 0.001). The Three studies (811 participants) showed an impact on OHRQoL (P-CPQ); the pooled RR (CI) was 16.992 (5.119, 28.865) showing statistically significant value (P < 0.001). Heterogeneity (I2) was high (99.6% and 99.2%); hence, random effect model was used. Sensitivity analysis of two studies (310 subjects) showed impact on OHRQoL (P-CPQ); the pooled RR (CI) was 22.124 (20.382, 23.866) showing statistically significant value (P < 0.001); the heterogeneity was low (I2 = 0.0). The risk of bias across studies assessed using the appraisal tool for cross sectional studies tool was found to be moderate. The reporting bias assessed using the dispersion on the funnel plot was found to be minimal. Authors' Conclusions: Children with MIH are about 17-25 times more likely to have impacts on the OHRQoL compared to children with no MIH. Evidence is of low quality due to high heterogeneity. The risk of bias was moderate and publication bias was low.

Ablation in Pancreatic Cancer: Past, Present and Future.

The insidious onset and aggressive nature of pancreatic cancer contributes to the poor treatment response and high mortality of this devastating disease. While surgery, chemotherapy and radiation have contributed to improvements in overall survival, roughly 90% of those afflicted by this disease will die within 5 years of diagnosis. The developed ablative locoregional treatment modalities have demonstrated promise in terms of overall survival and quality of life. In this review, we discuss some of the recent studies demonstrating the safety and efficacy of ablative treatments in patients with locally advanced pancreatic cancer.

Percutaneous Radiofrequency Ablation of Appendicular Skeleton Chondroblastoma-an Experience from a Tertiary Care Cancer Center.

PURPOSE: To evaluate safety and long-term efficacy of radiofrequency (RF) ablation in treatment of chondroblastoma. MATERIALS AND METHODS: This retrospective analysis comprised 27 consecutive patients with histopathologically proven chondroblastoma treated by RF ablation. The tumors were located in the proximal humerus (n = 6), proximal tibia (n = 8), proximal femur (n = 6), distal femur (n = 5), acromion process (n = 1), and lunate (n = 1). In 19 patients (70.3%), the tumor was in the weight-bearing area of the bone. Clinical response was assessed by comparing pain scores and functional assessment by Musculoskeletal Tumor Society (MSTS) score before and after ablation. Patients were followed for a minimum of 1 year to rule out complications and recurrence. RESULTS: Technical success rate was 100%. Mean pain score before the procedure was 7.34 (range, 7-9); all patients experienced a reduction in pain, with 25 (92.6%) patients reporting complete pain relief at 6 weeks. Mean MSTS score before the procedure was 15.4, whereas mean MSTS score at 6 weeks after the procedure was 28.6, suggesting significant functional improvement (P < .0001). Two patients developed osteonecrosis and collapse of the treated bone. There were no recurrences. CONCLUSIONS: Percutaneous RF ablation is a safe and effective option for treating chondroblastoma of the appendicular skeleton.

Case report on 5-fluorouracil induced cerebrovascular accident.

INTRODUCTION: 5-Fluorouracil is an antineoplastic agent generally used to treat various types of solid tumors. The common adverse drug reaction associated with 5-fluorouracil are myelosuppression, mucositis, diarrhea, and hand-foot syndrome. Neurological side effects such as headache, dizziness, convulsion, encephalopathy, and acute cerebellar syndrome are rare in nature. CASE PRESENTATION: We report a case of 5-fluorouracil induced cerebrovascular accident (CVA) in a patient with no risk factors for CVA before chemotherapy. A 37 years old female patient diagnosed with carcinoma rectum underwent six cycles of chemotherapy with 5- fluorouracil- calcium leucovorin- irinotecan (FOLFIRI regimen). After completing the last cycle, she developed headache, vomiting, and facial deviation along with high blood pressure (260/160 mmHg). MRI brain was done, and it revealed acute non-hemorrhagic lacunar infarct in the left half of pons. 5-fluorouracil induced CVA was suspected and was managed with dual antiplatelet, statin, and antihypertensives. CONCLUSION: The clinicians and clinical pharmacists must be aware about the potential of 5-FU to induce rare side effects such as CVA even in low risk patients in order to avoid permanent harm to the patient.

Systematic review on the genetic factors associated with skeletal Class II malocclusion.

AIM: The aim of this study is to review studies evaluating the role of genetics in skeletal class II malocclusion. OBJECTIVE: To assess the scientific evidence associating the role of genes in skeletal class II malocclusion. Materials and Methods: A complete search across the electronic database through PubMed, Cochrane, LILACS, BMC and manual hand search of orthodontic journals were done till May 2019. The keywords for the search included: "Genetics", "class II malocclusion", "maxillary prognathism", "mandibular retrognathism". DATA COLLECTION AND ANALYSIS: Studies were selected based on PRISMA guidelines. RESULTS: Articles were selected based on the inclusion and exclusion criteria. A total of 11 cross-sectional studies satisfied the inclusion criteria and were analyzed for the role of genes in skeletal class II malocclusion. Almost all the studies except for one revealed a positive correlation of genes with skeletal class II malocclusion. CONCLUSIONS: Out of the 11 studies included, a positive correlation of the genes with the skeletal II malocclusion was found in 10 studies. Genes FGFR2, MSX1, MATN1, MYOH1, ACTN3, GHR, KAT6B, HDAC4, AJUBA were found to be positively linked to skeletal class II malocclusion.

Plasmacytoid variant of urothelial carcinoma of the bladder manifesting as bilateral ureteral and small bowel obstruction.

Plasmacytoid urothelial carcinoma (PUC) is a rare variant of bladder cancer characterized by distinct histopathology and advanced stage at diagnosis. Multimodal treatment is usually indicated. We present a case of PUC causing bilateral ureteral obstruction with subsequent renal failure followed shortly by malignant small bowel obstruction, demonstrating the need for a high degree of clinical suspicion in diagnosis of this aggressive subtype. Moreover, the local invasiveness of the disease cannot be understated, given that it can rapidly spread with little radiologic evidence of progression until it is at an advanced stage.

PD-L1 pathway as a novel target in carcinosarcoma of the kidney and renal pelvis.

Carcinosarcoma of the kidney and renal pelvis (CSKP) is a rare and highly-aggressive malignancy characterized by rapid progression and widespread metastases. To date, few studies describe the natural history of the disease. We present a patient placed on pembrolizumab therapy for suspected metastatic colon cancer. The patient was found to have a right renal mass with caval extension on surveillance and ultimately underwent radical surgery revealing carcinosarcoma with positive PD-L1 expression with no evidence of recurrence to date. To our knowledge, this is the first case describing PD-L1 expression in CSKP and presents a novel pathway for future treatment algorithms.

CT-guided radiofrequency ablation in osteoid osteoma: Result from a tertiary cancer centre in India.

AIMS: The aim of this study is to evaluate the clinical efficacy of computed tomography (CT)-guided radiofrequency (RF) ablation as a minimally invasive therapy for osteoid osteoma. MATERIALS AND METHODS: This is a retrospective analysis of prospectively maintained data of 43 symptomatic osteoid osteoma patients who were treated by radiofrequency ablation (RFA). Forty out of 43 patients were naive cases and underwent primary treatment for osteoid osteoma with RFA, whereas 3 patients included in the study underwent RFA for local recurrence after having undergone surgical treatment. Diagnosis was based on clinical and characteristic imaging findings, and biopsy was done for cases with atypical presentation. Pre and post procedure Visual Analog Score (VAS) was documented in all cases. Monopolar RFA system was used in all patients, and the electrode was placed within the lesion nidus under CT guidance coaxially through 11G introducer needle. Ablation was performed at 90° C for 5 min. RESULTS: Technical success rate of intranidal placement of electrode was 100%. The primary clinical success in our study was 97.7% (42 of 43), and the secondary clinical success was 100%. Pre and postprocedure VAS score in our study group was 7.8 and 0.4, respectively. Mean follow-up period in our study was 48 months (Range: 4-129 months). One patient had recurrence of pain 4 years after treatment and was treated successfully by a second session. Minor complications were seen in 3 patients with two cases of RF pad burns and one case of skin burn at the treatment site, and these were managed conservatively. No patients developed temporary/permanent neurological deficits, and no procedure-related mortality was seen in our study. CONCLUSION: CT-guided percutaneous RFA is a simple, safe, minimally invasive, and highly effective treatment option for osteoid osteoma with good long-term pain control and potentially low disease recurrence.
