Comparison of Optic Nerve Sheath Diameter (ONSD) Measurements Obtained from USG Before and After Placement of Ventriculoperitoneal Shunt in Obstructive Hydrocephalus as a Surrogate Marker for Adequacy of Shunt Function: A Prospective Observational Study.

Introduction Optic nerve sheath diameter (ONSD) measured using ultrasonography has been widely used as a surrogate marker of elevated intracranial pressure. However, literature is sparse on the correlation between ONSD and ventriculoperitoneal (VP) shunt function, especially in adults with hydrocephalus. Our study was designed to assess the correlation between ONSD measured using ultrasonography before and 12 hours after VP shunt placement and the success of VP shunt placement assessed using computed tomography (CT) of the brain. Materials and Methods Fifty-one patients between 16 and 60 years of age, with obstructive hydrocephalus scheduled for VP shunt surgery were included in this prospective, observational study. ONSD measurements were obtained from both eyes prior to induction of anesthesia, immediately after the surgery, and at 6, 12, and 24 hours after the surgery. An average of three readings was obtained from each eye. Cerebrospinal fluid (CSF) opening pressure was noted after entry into the lateral ventricle. Noncontrast CT (NCCT) brain was obtained 12 hours after the surgery and was interpreted by the same neurosurgeon for signs of successful VP shunt placement. Results There was a significant reduction in ONSD in the postoperative period compared to ONSD measured preoperatively. The average ONSD (mean ± standard deviation) measured prior to induction of anesthesia, immediately after the surgery, and at 6, 12, and 24 hours after the surgery was 5.71 ± 0.95, 5.20 ± 0.84, 5.06 ± 0.79, 4.90 ± 0.79, and 4.76 ± 0.75 mm, respectively. The mean CSF opening pressure was 19.6 ± 6.9 mm Hg. Postoperative NCCT brain revealed misplacement of the shunt tip in only one patient. Conclusion ONSD measured using ultrasonography may be used as a reliable indicator of VP shunt function in adults with obstructive hydrocephalus.

Effect of Community-Based Health Education on Misconceptions Related to Caregiving for Cancer among Elderly in a Rural Area of Puducherry: A Pre-Post-Intervention Study.

Background and Aim: Families are crucial in providing comprehensive support to cancer patients, including physical, psychological, spiritual, and financial assistance. Unfortunately, cancer-related myths and stigma can have detrimental effects on those affected and their caregivers. This study aims to remove the misconceptions prevailing in a rural population of Puducherry regarding caregiving for cancer among elderly through a health education campaign. Materials and Methods: A pre- and post-intervention study was conducted among 217 adults above 18 years of age in a rural area of Puducherry. The intervention was delivered through pamphlet distribution, health talks, and discussion. Attitude, beliefs, and knowledge regarding the misconceptions about cancer were assessed in a five-point Likert scale and then the difference in the proportion of subjects with misconceptions about cancer before and after the intervention was tested using the McNemar test. Results: Among the respondents, 77% were females, 15% were illiterate, and 9.6% had a history of cancer in the family. About 23% felt cancer lends a bad name to the family and 24% considered palliative care as not necessary since end-stage cancer patients would die. Post-intervention, the perception that herbal items or diets may treat cancer declined from 45% to 18%, and that a cancer patient in the family lends bad name to the family declined from 23% to 3% (P < 0.001). Conclusions: Community-based intervention can effectively reduce misconceptions related to caregiving for cancer among elderly in rural areas. These interventions can also improve the quality of care and support provided to cancer patients.

Myths, beliefs, and attitude toward cancer among the family caregivers of cancer patients: A community-based, mixed-method study in rural Tamil Nadu.

Background and Aim: Family support is one of the most crucial components of cancer care. The familial beliefs and myths associated with cancer can seriously affect the quality of life and treatment outcome of cancer patients. This study intends to explore the prevailing myths, beliefs, and attitude toward cancer among the family caregivers of cancer patients. Materials and Methods: A community-based, exploratory, mixed-method study was conducted among family caregivers of cancer patients in Cuddalore and Villupuram districts of Tamil Nadu. Content analysis method was used for in-depth interviews. Sociodemographic characteristics and attitude of the study participants were described using proportions. Results: A common myth about causation of cancer was that it was contagious or of infective origin. Disbelief in tobacco's causation of cancer was found among the study participants. Family members' support was viewed as an essential component for cancer patients. Majority of the participants in the quantitative survey showed favorable attitude toward cancer patients. The common misconception about cancer treatment was that surgery/biopsy can spread cancer and herbal products can cure cancer. Conclusion: Even though a majority of the participants showed favorable attitude toward their cancer patients, false beliefs and myths regarding causation and treatment of cancer are prevalent in the community.

Comparison of the Analgesic Efficacy of Ultrasound-Guided Superficial Serratus Anterior Plane Block With Deep Serratus Anterior Plane Block in Patients Undergoing Modified Radical Mastectomy: A Randomized Clinical Trial.

Background Acute postoperative pain after breast cancer surgery adversely affects recovery and is an independent predictor of chronic postsurgical pain in these patients. Serratus plane blocks have been found to provide analgesia to the anterior hemithorax. However, trials comparing superficial serratus plane block and deep serratus block in breast cancer surgery patients are sparse. Methodology A total of 74 female patients with American Society of Anesthesiologists physical status I and II scheduled for elective modified radical mastectomy for breast cancer were randomized into two groups. Group A patients received a superficial serratus plane block with 30 mL of 0.25% bupivacaine, and group B patients received a deep serratus plane block with 30 mL of 0.25% bupivacaine. Postoperatively, the Numerical Rating Scale (NRS) score was measured during the immediate postoperative period, after 30 minutes and at one, four, eight, 16, and 24 hours, as well as on the second and third day. After discharge, the NRS scores were recorded in the second and third weeks and then monthly once for three months. All patients received patient-controlled analgesia with intravenous (IV) morphine. The duration of analgesia, pain scores, and 24-hour morphine consumption were also noted. Results In group A, the mean duration of analgesia (hours) was 5.51 ± 1.42, whereas in group B the mean duration of analgesia (hours) was 6.69 ± 1.18 (p < 0.01). NRS scores for pain during rest at 12 and 16 hours and NRS scores for pain during cough at eight, 12, and 16 hours, as well as at the third month were significantly lower in group B. However, morphine consumption was comparable between the groups. Conclusions Deep serratus plane block was associated with better NRS scores for pain on rest and coughing and prolonged duration of analgesia after a modified radical mastectomy. We conclude that the deep serratus plane block provides superior and extended analgesia than the superficial serratus plane block after a modified radical mastectomy.

A1C as a Prognosticator of Perioperative Complications of Diabetes: A Narrative Review.

Hemoglobin A1c (A1C) or glycated hemoglobin reflects the levels of blood glucose during the previous 8-12 weeks duration. It also helps us to diagnose diabetes in some cases, during the preoperative screening, who were initially missed out. Although the number of patients with diabetes undergoing various surgeries has increased many times, the role of A1C as a predictor for the complications during the perioperative phase remains intriguing. This could be due to various factors such as lack of best shreds of evidence, various cut-off levels of target A1C, variations of the patient population, presence of other comorbid conditions, and so on. This narrative review article presents the role of A1C as a reflector of perioperative adverse events in various surgeries and discusses the controversies surrounding it. We searched "PubMed Central" database with search criteria of "hemoglobin A1c, glycated hemoglobin, and perioperative complications" with publication date from January 01, 2010, to January 31, 2020, and found a total of 214 articles. We included only the relevant articles to our topic and added a few more articles that we found as "secondary references" from those articles to suit the structured headings of our narrative review and made it a total of fifty. To our knowledge, the majority of the studies published on this topic are of the "Retrospective analysis" type of study, besides no narrative review article available to date in the literature. We suggest that assessment of A1C levels preoperatively can be used as a routine practice for major procedures in patients with diabetes and for patients who have persistent high glucose values during preoperative screening regardless of whether a diagnosis of diabetes is established or not. We found that a cut-off of 8% is acceptable for the majority of the surgical procedures. However, it is better to have a cut-off of 7% or lower for procedures such as spine and joint replacement surgeries, cardiac surgeries, and so on. Further prospective studies involving a large population preferably with a multicenter design would provide us more clarity on this topic.

Chronic Pain and Associated Factors in India and Nepal: A Pilot Study of the Vanderbilt Global Pain Survey.

BACKGROUND: Evaluation and treatment of chronic pain worldwide are limited by the lack of standardized assessment tools incorporating consistent definitions of pain chronicity and specific queries of known social and psychological risk factors for chronic pain. The Vanderbilt Global Pain Survey (VGPS) was developed as a tool to address these concerns, specifically in the low- and middle-income countries where global burden is highest. METHODS: The VGPS was developed using standardized and cross-culturally validated metrics, including the Brief Pain Inventory and World Health Organization Disability Assessment Scale, as well as the Pain Catastrophizing Scale, the Fibromyalgia Survey Questionnaire along with queries about pain attitudes to assess the prevalence of chronic pain and disability along with its psychosocial and emotional associations. The VGPS was piloted in both Nepal and India over a 1-month period in 2014, allowing for evaluation of this tool in 2 distinctly diverse cultures. RESULTS: Prevalence of chronic pain in Nepal and India was consistent with published data. The Nepali cohort displayed a pain point prevalence of 48%-50% along with some form of disability present in approximately one third of the past 30 days. Additionally, 11% of Nepalis recorded pain in 2 somatic sites and 39% of those surveyed documented a history of a traumatic event. In the Indian cohort, pain point prevalence was approximately 24% to 41% based on the question phrasing, and any form of disability was present in 6 of the last 30 days. Of the Indians surveyed, 11% reported pain in 2 somatic sites, with only 4% reporting a previous traumatic event. Overall, Nepal had significantly higher chronic pain prevalence, symptom severity, widespread pain, and self-reported previous traumatic events, yet lower reported pain severity. CONCLUSIONS: Our findings confirm prevalent chronic pain, while revealing pertinent cultural differences and survey limitations that will inform future assessment strategies. Specific areas for improvement identified in this VGPS pilot study included survey translation methodology, redundancy of embedded metrics and cultural limitations in representative sampling and in detecting the prevalence of mental health illness, catastrophizing behavior, and previous traumatic events. International expert consensus is needed.

Effects of adding low-dose clonidine to intrathecal hyperbaric ropivacaine: A randomized double-blind clinical trial.

BACKGROUND: Clonidine added to bupivacaine prolongs the duration of anesthesia and postoperative analgesia with minimal side effects. Ropivacaine has lower lipid solubility and better safety profile as compared to bupivacaine. This study is designed to evaluate the effects of low-dose clonidine when added to hyperbaric ropivacaine. MATERIALS AND METHODS: Ninety patients belonging to American Society of Anesthesiologists-I scheduled for lower limb or lower abdominal surgeries under spinal anesthesia were randomly allocated into three groups (n = 30). Group R: 0.5% hyperbaric ropivacaine 12 mg + saline, Group 15C: 0.5% hyperbaric ropivacaine 12 mg + 15 mcg clonidine and Group 30C: 0.5% hyperbaric ropivacaine 12 mg + 30 mcg clonidine for spinal anesthesia in a total volume of 3.2 ml. Block characteristics, hemodynamic parameters, and side effects were monitored. RESULTS: Addition of low-dose clonidine to hyperbaric ropivacaine, significantly prolongs the duration of sensory and motor blockade as well as postoperative analgesia compared with placebo (mean ± standard deviation min; 152.50 ± 15.3, 246 ± 23.5, and 217 ± 37.73, respectively with 15 mcg clonidine, 193 ± 16.59, 284 ± 23.28, and 234.83 ± 36.45, respectively with 30 mcg clonidine, 131 ± 14.7, 211.5 ± 24.39, and 192.33 ± 37.02, respectively with saline). The addition of low-dose clonidine significantly increases the incidence of intra-operative hypotension (46.7% and 83.3%, respectively compared to 16.7%), bradycardia (6.7% and 23.3%, respectively compared to 0%). CONCLUSIONS: Addition of low-dose clonidine to intrathecal hyperbaric ropivacaine causes a significant prolongation of the duration of sensory and motor blockade as well as postoperative analgesia compared with saline placebo. However, it increases the incidence of hypotension and bradycardia which can be managed with routine clinical measures.
