    Abstract Background: During transnasal transsphenoidal pituitary surgery (TNTSS), the primary objective is to maintain stable hemodynamics while ensuring ideal surgical conditions. This study aimed to investigate the effect of nebulized dexmedetomidine on hemodynamic parameters and the quality of the surgical field during TNTSS.
    Methods: Seventy-five patients scheduled for TNTSS were randomized into three groups of 25 each and received preoperative nebulization with 5 mL of nebulizing fluid consisting of 1.5 μg/kg of dexmedetomidine with saline in dexmedetomidine (D) group; 1.5 μg/kg of dexmedetomidine with 2% lignocaine in dexmedetomidine-lignocaine (DL) group and normal saline in the control (S) group. Heart rate (HR), mean blood pressure, Formmers score, anesthetic requirement, and emergence were evaluated for each group.
    Results: Group S had significantly higher HR and mean arterial pressure than the other two groups across various time points during surgery (
    Conclusion: The administration of nebulized dexmedetomidine, both alone and in combination with lignocaine, resulted in stable hemodynamics, favorable operative conditions, reduced anesthetic requirement, and facilitated prompt emergence during TNTSS. Nebulized dexmedetomidine proved superior to its combination with lignocaine across all evaluated parameters.

    Abstract Objective: To retrospectively evaluate the safety and technical efficacy of percutaneous radiofrequency ablation (RFA) of surface hepatocellular carcinoma (HCC) in comparison to intraparenchymal HCC in cirrhotic patients.
    Materials and methods: Surface lesions were defined as tumours located or reaching within 1cm of liver capsule including exophytic lesions. Seventy-four surface HCC including 21 exophytic in 58 patients (surface group) and 60 intraparenchymal HCC in 54 patients (intraparenchymal group) measuring up to 4 cm in maximum extent underwent percutaneous [ultrasound (US) or computed tomography-guided (CT-guided)] RFA. The response to the treatment was assessed by contrast enhanced CT/magnetic resonance imaging (MRI) done at 1, 3, 6, 9, and 12 months of RFA and thereafter every 4-6 months. In case of features suggesting residual disease, a repeat RFA was performed. The technical success after single-session RFA, complications and disease recurrence rates were calculated and compared between two groups.
    Results: Technical success achieved after first session of RFA in surface HCC was 95% (70/74) and intraparenchymal HCC was 97% (58/60). Hundred percent secondary success rate was achieved in both groups after second repeat RFA in residual lesion. No major difference in complication and local recurrence rate in both group on follow-up in surface HCC and intraparenchymal HCC. No case of needle track, peritoneal seeding, and treatment mortality was found.
    Conclusions: The complication rate and efficacy of RFA for surface and exophytic HCC's were comparable to that of intraparenchymal HCC. Hence surface and exophytic lesions should not be considered a contraindication for RFA in cirrhotic patients.

    This book deliberates on the various aspects of plant-based nutrition. Plant-based nutrition has numerous potential health benefits as it is low on calories nevertheless high on nutrient density and satiety, and also nutrient supplementation makes them wholesome diets. Starting with the importance of biodiversity contributing to the nutrition, the book discusses the development or utilization of nutrient-dense crops/foods with their bioavailability properties and health effects. Further, it deals with the enrichment of micronutrients through bio-fortification, fortification, the role of food matrix, and nutrient bioavailability, including the role of plant-based milk alternatives. The linkage between food and health is also being discussed in the context of anti-nutritional factors, metabolic fate of the food, and genomics. Finally, the implications of next-gen biotech crops and food safety issues imperative to define the concept of safe nutrition are discussed. With contributions from plant nutrition experts, this book serves as a one-stop reference for plant scientists, food technologists, and nutritionists looking to understand the concept of plant-based nutrition and its linkage with human health.

    Abstract BACKGROUND : The prime duty of any anesthesiologist is to relive pain in the perioperative period. Today regional anesthesia is well established as equal to general anesthesia in effectiveness and patient acceptability. Regional anesthesia is blocking of peripheral ne rve conduction in a reversible way using local anesthetic agents. For surgeries on upper extremities, particularly in emergency surgeries, regional anesthesia has many advantages over general anesthesia. The brachial plexus is approached at the level of tr unks and the compact arrangement of trunks at the supraclavicular level gives a high success rate with minimum local anesthetic drug volume and a dense and fast onset of the block. To prolong the duration of analgesia various drugs have been studied as adj uvants to the local anesthetics. This study is intended to determine the effects of adding Clonidine to Bupivacaine in brachial plexus blockade by Nerve locator assisted supraclavicular approach, with regard to the onset, intensity and duration of blockade along with its analgesic efficacy. METHODS : Forty adult patients of both sexes in the age group of 20 - 60 years of weight ranging from 50 - 70kg belonging to ASA I/II category posted for various types of upper limb surgeries the patients were randomly alloca ted into two groups,. Supraclavicular brachial plexus block was performed via peripheral nerve locator assisted subclavian perivascular technique. Group – B ( B upivacaine alone) – 20 patients received 30 ml of 0.375%Bupivacaine with 2ml of 0.9% sodium chloride solution. Group – BC ( B upivacaine + C lonidine) – 20 patients received 30ml of 0.375%Bupivacaine with Clonidine hydrochloride 100μg (1ml of 150μg diluted with 2ml 0.9% Na C l solution. From that 2ml used fo r study. ( T he following parameters are assessed Onset of blockade, Duration of blockade, Intensity of blockade, Sedation, Quality of analgesia, Haemodynamic changes & Complications if any RESULTS: Onset time for both motor and sensory block was quicker in the Bupivacaine with clonidine group, Time taken for completion of both motor and sensory blockade was, significantly lesser in clonidine group, There was no difference between the groups in the intensity of blockade., The mean duration of both sensory & m otor blockade was significantly prolonged in clonidine group, Sedation was statistically significant with Bupivacaine - clonidine group in the intraoperative period, There was no haemodynamic instability in both the groups in the study period, There was no c omplication due to the addition of 100μg clonidine to Bupivacaine CONCLUSION : clonidine 100μg (in 2ml)when used as an additive to 0.375% Bupivacaine(30ml) solution for Supraclavicular brachial plexus block, quickens the onset of sensory & motor blockade an d prolongs the duration of sensory & motor blockade. It also improves the quality of post - operative analgesia with mild intraoperative sedation and decreases the heart rate without any haemodynamic instability. Hence, clonidine can be considered as a safe additive to local anaesthetic solution for brachial plexus blocks.

    Abstract BACKGROUND: Pain is a subjective experience with sensory and emotional components that are inextricably linked to each other. P ain during labour is very intense for many mothers. Severe labour pains may adversely affect both mother and fetus. Variety of regional anal gesia techniques are available, Of all these techniques epidural analgesia using local anaesthetics and opiates has gained popularity as a safe and effective technique of pain relief largely replacing other modalities. AIM: The present study was undertaken to compare bupivacaine and fentanyl with a combination of bupivacaine and butorphanol by intermittent bolus epidural technique in relieving pain during labour. DESIGN: Randomized control study . METHODS: A total number of 100 parturients studied were divid ed into two groups randomly. Group - 1: received a combination of Bupivacaine and Fentanyl. The initial bolus dose was 0.1% Bupivacaine 10ml with 2mcg/ml [20mcg] of Fentanyl and top up doses were 0.1% Bupivacaine with Fentanyl 2mcg/ml [10ml]. Group - 2: This G roup received a combination of Bupivacaine and Butorphanol. The initial bolus dose was 0.1% Bupivacaine 10ml with 0.01% of Butorphanol [1mg] and top up doses were with 0.1% Bupivacaine [10ml]. Maternal blood pressure, pulse rate, fetal heart rate were moni tored every 1 - 2 min for first 10 min and then every 5 - 10 min for subsequent 30 min and later every half an hour. Time of onset of analgesia, level of sensory blockade and motor blockade, if any was noted. VISUAL ANALOGUE PAIN SCALE [VAPS] assessed pain a t different time intervals. The sedation was assessed by WILSON GRADING, BROMAGE SCALE assessed the motor blockade. RESULTS: The onsets of analgesia were quicker in group - 1 parturients who received 0.1% bupivacaine with 0.0002% fentanyl. The duration of anal gesia with the 1st dose was significantly more in the group - 2 also the requirement of top up doses was also less in group - 2 and also the quality in group - 2 was superior. There was no significant increase in the requirement of instrumentation, surgical inte rvention in both the groups. Neonatal outcome was good and almost equal in both the groups without any respiratory depression even with addition of low dose butorphanol by epidural route. CONCLUSION : From this study it may be concluded that using a combina tion of 0.1% Bupivacaine with 1mg Butorphanol during epidural analgesia for labour provides excellent pain relief, prolonged duration of action with simultaneously decreasing the top - ups required, thereby reducing the total local anesthetic requirement com pared to 0.1% bupivacaine with 0.0002% fentanyl [20mcg]
