RESUMO
We present an interesting and rare case of Capillaria hepatica infection in a 2-year-old boy, who presented with fever, rash, hepatomegaly and peripheral eosinophilia. FNAC of hepatic lesion showed parasitic eggs and PCR from the aspirate confirmed the diagnosis. We describe the cytomorphological features and provide educational multiple-choice questions related to the topic.

BACKGROUND: Conventional fascial plane block approaches for upper abdominal surgeries spare the lateral cutaneous nerve. An external oblique intercostal block (EOIB) may be suitable for upper abdominal incisions as it blocks the lateral and anterior branches of the intercostal nerves T6-T10. However, there is a paucity of studies evaluating this block in clinical settings. The study aimed to compare the analgesic efficacy of combined EOIB and rectus sheath block with local infiltration analgesia (LIA) in laparoscopic cholecystectomy (LC). METHODS: After obtaining written informed consent, 70 patients were randomly allocated to undergo right-sided EOIB with 20 ml and left-sided RSB with 10 ml of 0.25% bupivacaine at the end of surgery (group ER, n = 35). Patients in the LIA group (n = 35) underwent local infiltration at the port site using 20 ml of the same solution (group LIA, n=35). RESULTS: The visual analog scale scores with combined EOI and RSB were significantly lower than those with LIA at 1, 2, 4, 8, and 12 h (P < 0.001). Rescue analgesics were required by 65.7% and 14.3% of the patients in the LIA and block groups, respectively (P < 0.001). The time to first rescue analgesic was significantly greater in the ER group than that in the LIA group (2.8 ± 1.10 vs. 1.6 ± 0.50 h; P = 0.012). The number of times rescue analgesia was required was significantly lower in the ER group than that in the LIA group (1.00 ± 0.00 vs. 1.83 ± 0.72; P = 0.015). Nausea and vomiting scores were higher in the LIA group than those in the ER group (P < 0.001). Patient satisfaction scores were higher in the ER group than those in the LIA group. CONCLUSIONS: EOIB combined with RSB provides superior analgesia compared with LIA and should be considered for LC.
RESUMO
Though permanent vocal cord palsy consequent to recurrent laryngeal nerve (RLN) injury is rare following thyroidectomies, its consequences are grave enough for it to be the most feared complication postoperatively. Anesthesiologists and surgeons take various precautions to prevent its occurrence and employ various methods for its early detection. They include direct visualization of the nerve intraoperatively, use of intraoperative nerve monitoring, and post-extubation visualization of vocal cord mobility by use of direct or indirect methods. In the present narrative review, we aim to discuss the clinical evidence pertaining to the various methods adopted for the prevention and early detection of RLN palsy during thyroidectomy.
RESUMO
Background: Ultrasound (US)-guided costoclavicular block (CCB) is a promising new approach to brachial plexus (BP) block which is increasingly being utilized. Conventionally, the costoclavicular space (CCS) has been described to contain three cords. However, there may be variations in the neural pattern of the BP which is important to know to prevent inadvertent injury. We intend to describe the variations in neural patterns from retrospective scans of patients receiving costoclavicular BP block. Methods: The stored US images of patients who had received BP block using the CCB for surgery at the level of the elbow or below in the last year (from March 2021 to March 2022) were analyzed by two investigators independently. The clinical data were retrieved from the records of the same patients for the study outcomes. We collated the variations of the neural pattern, the number of neural structures seen, and the echogenicity of the structures in the costoclavicular BP space. Results: In the CCS, the median number of neural structures was 4.5 (minimum of 3 to maximum of 8). With the BP lateral to the axillary artery and sandwiched between the subclavius-pectoralis minor superiorly and the serratus anteriorly inferiorly, numerous variations in the neural structures were noted. The most common arrangement was caterpillar-like (28.6%) and pecker-like (20.3%). The neural structures were found to be hypoechoic in the majority (66%). Conclusion: The CCS hosts several mostly hypoechoic neural structures which may be the variations of the cords or the extension of BP divisions. These new findings have been unreported in the recent past.
RESUMO
Geological formations have superior wickability and support the absorption of water and oils into narrow spaces of Earth's crust without external assistance. In this study, we present speleothem inspired heterogeneous porous and wicked copper (Cu)/nickel (Ni) interfaces for enhanced nucleate boiling of water/ethanol mixtures for energy-efficient separation processes. The incorporation of Ni strands within the copper particle matrix significantly enhanced heat transfer. Compared to plain copper, the Cu/Ni speleothem surfaces exhibited a 61% increase in the heat transfer coefficient for water/ethanol mixtures and a 332% increase for water, with a 58% faster onset of nucleate boiling. This enhancement was attributed to Marangoni and Soret effects at the Cu/Ni interfaces, driven by surface tension and concentration gradients. Furthermore, the synergistic wicking action of the Ni strands facilitated rewetting of the surface, replenishing liquid to the porous nucleation sites and preventing surface dry-out, thereby improving the overall heat transfer performance.
RESUMO
BACKGROUND: Pediatric airway management requires careful clinical evaluation and experienced execution due to anatomical, physiological, and developmental considerations. Video laryngoscopy in pediatric airways is a developing area of research, with recent data suggesting that video laryngoscopes are better than standard Macintosh blades. Specifically, there is a paucity of literature on the advantages of the C-MAC D-blade compared to the McCoy direct laryngoscope. METHODS: After Ethics Committee approval, 70 American Society of Anesthesiologists physical status 1 and 2 children aged 4-12 years scheduled for elective surgery under general anesthesia were recruited. Patients were randomly allocated to intubation using a C-MAC video laryngoscope size 2 D-blade (Group 1) and a McCoy laryngoscope size 2 blade (Group 2). The Intubation Difficulty Scale (IDS) for ease of intubation was the primary outcome, while Cormack-Lehane grades, duration of laryngoscopy and intubation, hemodynamic responses, and incidence of any airway complications were secondary outcomes. RESULTS: Both groups were comparable in terms of patient characteristics. The median (IQR) Intubation Difficulty Scale (IDS) score was better but was statistically nonsignificant with C-MAC (0 [0-0] vs. 0 [0-2], p = .055). The glottic views were superior (CL grade I in 32/35 vs. 23/35, p = .002), and the time to best glottic view (6 s [5-7] vs. 8.0 s [6-10], p = .006) was lesser in the C-MAC D-blade group while the total duration of intubation was comparable (20 s [16-22] vs. 18 s [15-22], p = .374). All the patients could be successfully intubated on the first attempt. None of the patients had any complications. CONCLUSION: The C-MAC video laryngoscope size 2 D-blade provided faster and better glottic visualization but similar intubation difficulty compared to McCoy size 2 laryngoscope in children. The shorter time to achieve glottic view demonstrated with the C-MAC failed to translate into a shorter total duration of intubation when compared to the McCoy laryngoscope attributable to a pronounced curvature of the D-blade.

BACKGROUND: Radiofrequency ablation of genicular nerves is recommended to ameliorate the pain of osteoarthritis of the knee. However, long-term efficacy in patients with persistent pain following total knee arthroplasty remains elusive. The current study aimed to evaluate radiofrequency ablation of genicular nerves using a hybrid technique to manage severe incapacitating pain and quality of life following surgery. METHODS: This prospective, observational study included patients suffering from intractable knee pain with scores > 4 on the Numeric rating scale after 6 months of total knee arthroplasty. Therapy included radiofrequency ablation of the superior medial, lateral, and inferior medial genicular nerves using a hybrid technique. The Numeric rating scale and Oxford Knee Score for quality of life were assessed before therapy and at 1-, 3- and 6 months following treatment. RESULTS: Average pain scores reduced from 8.4 ± 1.3 (admission) to 3.3 ± 1.4 (1 month; p= <0.001) but subsequently started to increase to 4 ± 1.2 (3 months; p = 0.58), and 5.6 ± 0.9 (6 months; p= <0.001). Average Oxford Knee Score significantly improved from 14.2 ± 5.9 (admission) to 38 ± 8.6(1 month); p= <0.001, but these too subsequently reduced to 36.4 ± 7.9 (3 months); p= 1, and 22.5 ± 12.5(6 months); p= <0.001. CONCLUSIONS: Ultrasound-guided radiofrequency ablation of genicular nerves diminishes intractable pain and disability in patients with chronic knee pain following total knee arthroplasty. Treatment is safe and effective, however, the benefit declined by 6 months. A repeat block would be necessary if the pain score worsens.

BACKGROUND: Novel interfascial plane blocks like PEricapsular Nerve Group (PENG) and SupraInguinal Fascia Iliaca (SIFI) blocks are effective for management of hip fracture pain. We compared the difference in the distribution of the dye injected and nerves stained by the addition of the SIFI block to the PENG block. METHODS: A total of 24 designated dye injections were performed in eight soft-embalmed cadavers. Under ultrasound guidance 20 ml green ink injected bilaterally in PENG block and 30 ml methylene blue dye was injected in the SIFI block on the right side. The cadavers were dissected 24 h later to assess the extent of dye spread. RESULTS: Extensive spread of dyes was seen on both side of iliacus muscle on the right side, but blue dye was not visible medial to the psoas tendon. The subcostal and iliohypogastric nerves were stained green in the infra-inguinal region. On the left side (PENG alone), the anterior division of the obturator, femoral and saphenous nerve (7/8) and iliohypogastric nerves (3/8) were stained in the infrainguinal region. In the suprainguinal region, the femoral nerve (5/8), accessory obturator nerve (3/8), lateral femoral cutaneous (1/8) and nerve to rectus femoris (4/8) were stained. The main obturator nerve trunk was spared with both injections while its anterior branch and accessory obturator nerve were stained with the PENG injection. CONCLUSION: The study findings indicate that combined PENG + SIFI injections lead to an extensive craniocaudal and longitudinal spread along the iliacus muscle. We perceive that the combination of these two injections will have a superior clinical outcome.

PURPOSE: Nasotracheal intubation (NTI) is required for surgery in oropharyngeal (OP) carcinoma patients, but it may be challenging because of distorted anatomy, mucosal congestion, and increased risk of bleeding. Flexible bronchoscopy (FB)-guided NTI is preferred in these cases but has limitations. In this randomized controlled study, we sought to compare C-MAC® D-BLADE-guided videolaryngoscopy (VL) (Karl Storz SE & Co. KG, Tuttlingen, Germany) with FB for NTI under general anesthesia in patients with OP carcinomas. METHODS: We randomized a total of 100 patients with OP carcinoma and El-Ganzouri's risk index (EGRI) < 7 to undergo NTI under general anesthesia with FB (n = 50) or C-MAC D-BLADE-guided VL (n = 50). The primary outcome was the total intubation time. We also recorded the time to glottis view, nasal intubation difficulty scale (NIDS) score, best percentage of glottis opening score, and complications. RESULTS: The median [interquartile range (IQR)] total intubation time was shorter with VL than with FB (total intubation time, 38 [26-43] sec vs 60 [52-65] sec; difference, -20 sec [95% confidence interval (CI), -27 to -11]; P < 0.001). Similarly, the median [IQR] time to glottis view was shorter with VL compared to FB (8 [6-9] sec vs 22 [14-25] sec; difference, -13 sec [95% CI, -17 to -10]; P < 0.001). The median NIDS score was higher with VL (difference, 2 [95% CI, 2 to 3]; P < 0.001). The incidences of airway trauma (two cases with FB vs seven with VL; P = 0.30) and postoperative sore throat (ten cases in both groups; P = 0.56) were similar. CONCLUSION: Compared to FB, C-MAC D-BLADE-based VL reduced the total time for nasal intubation oropharyngeal carcinoma patients, potentially representing an acceptable alternative in selected cases.

RéSUMé: OBJECTIF: L'intubation nasotrachéale est nécessaire pour la chirurgie chez la patientèle atteinte de carcinome oropharyngé, mais elle peut être difficile en raison d'une anatomie déformée, d'une congestion des muqueuses et d'un risque accru de saignement. Dans ces cas, il est préférable d'utiliser une intubation nasotrachéale guidée par bronchoscopie flexible (BF), mais cette modalité a ses limites. Dans cette étude randomisée contrôlée, nous avons cherché à comparer la vidéolaryngoscopie guidée par lame D-BLADE C-MAC® (VL) (Karl Storz SE & Co. KG, Tuttlingen, Allemagne) à la BF pour réaliser l'intubation nasotrachéale sous anesthésie générale chez les patient·es ayant un carcinome oropharyngé. MéTHODE: Au total, nous avons randomisé 100 personnes atteintes d'un carcinome oropharyngé et présentant un indice de risque d'El-Ganzouri (EGRI) < 7 à bénéficier d'une intubation nasotrachéale sous anesthésie générale par BF (n = 50) ou par VL guidée par lame D-BLADE C-MAC (n = 50). Le critère d'évaluation principal était le temps d'intubation total. Nous avons également enregistré le temps écoulé jusqu'à la visualisation de la glotte, le score sur l'échelle de difficulté de l'intubation nasale (NIDS), le meilleur pourcentage de score d'ouverture de la glotte et les complications. RéSULTATS: La durée totale d'intubation médiane [écart interquartile (ÉIQ)] était plus courte avec la VL qu'avec la BF (durée totale d'intubation, 38 [2643] sec vs 60 [52 à 65] secondes; différence, −20 sec [intervalle de confiance (IC) à 95 %, −27 à −11]; P < 0,001). De même, le temps médian [ÉIQ] jusqu'à la visualisation de la glotte était plus court avec la VL qu'avec la BF (8 [69] sec vs 22 [14 à 25] secondes; différence, −13 sec [IC 95 %, −17 à −10]; P < 0,001). Le score médian sur l'échelle NIDS était plus élevé avec la VL (différence, 2 [IC 95 %, 2 à 3]; P < 0,001). L'incidence des traumatismes des voies aériennes (deux cas avec la BF vs sept avec la VL; P = 0,30) et le mal de gorge postopératoire (dix cas dans les deux groupes; P = 0,56) étaient similaires. CONCLUSION: Par rapport à la BF, la VL guidée par lame D-BLADE C-MAC a réduit le temps total d'intubation nasale pour les personnes atteintes d'un carcinome oropharyngé, ce qui représente potentiellement une alternative acceptable dans certains cas.

Multisystem inflammatory syndrome in children (MIS-C) is an immune response inciting multiorgan dysfunction and a shock-like state which is typically seen in children 2 to 6 weeks after either a coronavirus disease-19 infection or exposure. When such a child comes for any surgery, perioperative anesthetic management demands multidisciplinary involvement and individualized case-based decision-making. Due to the novelty of the condition, there are limited data on anesthetic implications in these patients. Anesthetic management in the affected children is dynamic depending on the organ systems involved and the progression of the disease state. Though the long-term effects of the syndrome are largely unknown, we hope that awareness of the MIS-C-associated complications may help anesthesiologists involved in childcare. Herein, we put forward challenges and clinical dilemmas we faced during the anesthetic management of three children with MIS-C presenting for emergency and elective surgery.

Lumbar erector spinae plane block (ESPB) is effective for spine surgeries but is deep and technically demanding. Sacral ESPB is a novel approach for sacrococcygeal procedures and can potentially cover lumbar dermatomes by the cranial drug spread. This is the first reported case series demonstrating the potential analgesic efficacy of sacral ESPB for lumbar spine surgeries. Five patients with radiculopathy at the lumbosacral area level were scheduled for transforaminal lumbar interbody fusion (TLIF). General anaesthesia was induced as per standard practice. All patients received sacral ESP in a prone position under ultrasound guidance with a needle inserted in-plane while targeting the fascial plane between the S2 median crest and overlying muscles. All the included patients had good analgesia in the postoperative period and required minimal opioid analgesic doses. Sacral ESPB is an easy, effective, and safe technique in the scheme of multimodal analgesia for TLIF surgeries as a component of pre-emptive analgesia, where the main goal is an opioid-sparing effect.
RESUMO
Various factors (e.g., infections) have been postulated to trigger Kawasaki disease (KD) in genetically predisposed individuals. Whether neoplasms can trigger KD is largely unknown due to paucity of data. Herein, we provide a detailed account of KD occurring in temporal proximity (within 6 months) to neoplasms ('neoplasm-KD'). Patients with 'neoplasm-KD' diagnosed/treated at our center from January 1994 to May 2021 were included. Additionally, we performed a systematic literature review (as per PRISMA 2020 guidelines) utilizing PubMed, Web of Science and Scopus databases to retrieve details of all patients with 'neoplasm-KD' reported till June 2021. Patients with multisystem inflammatory syndrome in children were excluded. As all reports pertained to case description(s), risk of bias assessment was not performed. The details of patients with 'neoplasm-KD' were analyzed using SPSS software. Primary and secondary outcomes were occurrence of coronary artery abnormalities (CAAs) and clinical characteristics of 'neoplasm-KD', respectively. A total of 25 patients (data from 18 reports) were included in the 'neoplasm-KD' dataset. The most frequently diagnosed neoplasm was acute lymphoblastic leukemia followed by neuroblastoma and acute myeloblastic leukemia. Overall, CAAs were noted in 48% of patients. Interval between diagnoses of KD and neoplasm was shorter in patients with CAAs as compared to patients with normal coronary arteries (p-value = 0.03). Besides providing a comprehensive description of 'neoplasm-KD', this study raises a possibility that neoplasms might trigger KD. Also, 'neoplasm-KD' may be associated with a higher risk of development of CAAs. However, the small size of 'neoplasm-KD' dataset precludes definitive conclusions regarding this association. Funding: nil. Registration: PROSPERO (CRD42021270458).
This study is the first exhaustive description of cancers and Kawasaki disease (KD) occurring in close temporal proximity. Nearly half of these patients develop coronary artery abnormalities. In KD, persistent lymphadenopathy, enlargement of liver/spleen and development of low blood cell counts should trigger evaluation for cancer. Our study also raises a possibility that cancers might occasionally trigger KD.

Centipede bites are reported in many parts of tropical and subtropical countries, such as India. Centipede envenomation produces significant local symptoms, with pain being the most prominent symptom. The emergency department (ED) plays a crucial role in managing the victims through appropriate pain management and control of other local and systemic symptoms. Nonopioids and weak opioids, along with local measures, are often employed, but the intense pain is often refractory to these conventional techniques. Regional anesthesia has numerous benefits over these traditional measures, such as avoidance of polypharmacy and its consequent systemic adverse effects, excellent quality of pain control, and decreased need or avoidance of hospital admission. The applications of regional anesthesia have recently increased tremendously in the ED but are unreported for the management related to centipede bites. We report a case of centipede bite in which conventional analgesics did not help, and the pain was successfully managed by low-volume selective sensory peripheral nerve block.

Familial hemophagocytic lymphohistiocytosis (HLH) is an inherited disorder characterized by systemic hyperinflammation caused by an uncontrolled immune response mediated by T-lymphocytes, natural killer (NK) cells, and macrophages. Most children with familial HLH present within first 2 years of life and can have fatal disease unless hematopoietic stem cell transplant (HSCT) is performed (1). However, few patients may have late presentation and prolonged survival. With increasing awareness and facilities to identify HLH these disorders are being identified beyond infancy (2-4). Clinical and laboratory features are often similar to other primary immune deficiency diseases and pose diagnostic challenges (4-6). We report two patients who presented beyond the first decade of life with HLH, granulomatous inflammation, hypogammaglobulinemia, reduced B cells and were diagnosed to have familial HLH type 5 due to defect in STXBP2 gene.

PURPOSE: A videolaryngoscope(VL) with an intubation conduit like KingVision channeled(KVC) blade may provide an added advantage over a non-channeled VL like a KingVision non-channeled (KVNC) blade and direct laryngoscope (DL) for acquiring and retention of intubation skills, especially in novices. METHODS: In this prospective two-period randomized crossover trial, one hundred medical students used three laryngoscopes KVC, KVNC and DL for intubation following standardized training with the study devices using a Laerdal Airway Management Trainer. After one month, all participants attempted intubation, in the same manner, using all devices. The duration of intubation, modified Cormack-Lehane (CL) grade, percentage of glottic opening (POGO) score, first-attempt success, number of attempts, ease of intubation and dental trauma was recorded. The retention of intubation skills after 1 month was also assessed on the same parameters. RESULTS: Median intubation times of KVC and DL were comparable and significantly better than KVNC (P < 0.001). The median POGO score was better with both videolaryngoscopes when compared with DL. The ease of intubation (P < 0.0012) and first-attempt success rate (P = 0.001) at the time '0' was significantly better with KVC compared to KVNC and DL. KVC fared better with respect to these intubation parameters during intubation after one month as well. CONCLUSION: KVC performed better in terms of time to intubation, success rate and ease of procedure as compared to KVNC and DL, both for acquisition and retention of skill. Hence, we advocate that KVC should be the preferred device over KVNC and DL for teaching intubation skills to novices.

Gastrointestinal endoscopies are often done in the prone position and anesthesiologists are needed to provide sedation. Airway access is limited in the prone position and may make timely airway management difficult in case of airway obstruction during sedation. Specialized laryngeal mask airway devices customized for endoscopy procedures like LMA® Gastro™ can be inserted in the prone position and may help anesthesiologists tide over such crisis situations while simultaneously allowing the endoscopy procedures through the dedicated conduit available for inserting the endoscopes. We have described one such case managed successfully by inserting LMA® Gastro™ in the prone position.
