A Realistic Ingeniously Designed Cleft Palate Simulator for Training of Residents: Bridging the Gap Between Theory and Practice.

OBJECTIVE: Cleft palate is a congenital deformity that presents significant challenges in surgical correction. Proper training with an educational model for can greatly enhance the learning curve and improve patient outcomes. This article discusses the development and evaluation of an economical cleft palate model designed to enhance surgical skills and confidence among residents. DESIGN: The model was constructed using dental casts, acrylic resin, foam sheets, double-sided adhesives, infant feeding tubes, and red dye. SETTING: Tertiary care center. PARTICIPANTS: Surgical residents. MAIN OUTCOME MEASURE: The assembly time and material costs were recorded. To evaluate its effectiveness, participants' feedbacks were collected and analyzed. RESULTS: The cleft palate model was produced at a cost of 250 INR per unit, with assembly taking approximately 15 minutes. Overall, 32 residents completed the simulation exercise of cleft surgery on the model. Participants gave the model an average score of 4 (±0.60) for realistic anatomical appearance, 3.5 (±1.3) for replicating the tactile nature of human tissue. Anatomical accuracy and ability to manipulate tissue and perform suturing received a rating of 3.4 (±1.1) and 3.7 (±0.81), respectively. The model's value as a training tool scored 4.4 (±0.51), with an overall satisfaction rating of 4.6 (±0.22) among residents. CONCLUSION: Our cleft palate model offers an economical, practical, and accessible solution for surgical training. This model is a viable alternative to more complex and expensive training tools and potentially enhancing the training of healthcare professionals in cleft palate repair.

Endoscopic drainage versus percutaneous drainage for the management of infected walled-off necrosis: a comparative analysis.

BACKGROUND: Comparative data on percutaneous catheter drainage (PCD) vs EUS-guided drainage (EUS-D) for management of symptomatic walled-off-necrosis (WON), specially infected WON with/without organ failure(OF) is limited. METHODS: Patients with symptomatic WON were divided into two groups of PCD and EUS-D, depending on the modality of drainage. Resolution of OF, adverse events, and other outcome measures were recorded. The two modalities were compared among infected WON sub-cohort and also degree of solid component (SC). RESULTS: 218 patients (175 males; 80.3%) were included who underwent either PCD (n = 102) or EUS-D (n = 116). Clinical success was significantly higher in the EUS-D group (92.1% vs 64.6%; p < 0.0001) and even for infected WON (n = 128) (p = 0.004), with higher (p = 0.007) and faster (p < 0.0001) OF resolution. Other outcome measures including mortality were significantly higher in the PCD group. Among subgroups, PCD with >40% SC had the worst clinical success/OF resolution rates, while EUS-D with <40% SC had the best outcomes. CONCLUSION: EUS-D should be preferred over PCD in the management of WON, infected or otherwise, for higher clinical success, and higher/faster resolution of OF. PCD should be avoided in WON with>40% SC.

Per Oral Endoscopic Myotomy for the Management of Large Esophageal Diverticula (D-POEM): Safe and Effective Modality for Complete Septotomy.

With the advent of the technique of sub-mucosal tunnelling, peroral endoscopic myotomy (POEM) has been used for the treatment of esophageal diverticulum, which otherwise is a recurring problem with conventional flexible endoscopic treatment due to incompleteness of septotomy. This study reports our experience of the use of diverticular POEM (D-POEM) technique in the management of large esophageal diverticulum. This is a retrospective study of prospectively maintained database including all consecutive patients with symptomatic esophageal diverticulum presenting at a tertiary care academic center. D-POEM was performed using the technique of submucosal tunnelling and septotomy. Besides baseline parameters, technical success, clinical success, size of diverticula, procedure time, complications and symptom recurrence on follow up were noted. A total of five patients (4 males; median age 72) were included with an average Charlson comorbidity index of 3.2 ± 0.8. Of them, three had Zenker's while two had epiphrenic diverticulum. The median symptom duration was 12 months with a mean diverticulum size of 68.8 ± 1.9 mm. The mean procedure time was 64.80 ± 12.6 min. with a mean septotomy/myotomy length of 79.44 ± 12.2 mm. Minor adverse events were noted intra-procedure in two cases. Clinical success achieved in all cases with a significant mean dysphagia score reduction from 2.20 to 0.20 post procedure (p = 0.011). On a median follow up of 280 days (range 98-330), none had recurrence of symptoms. Our data highlighted that complete septotomy by D-POEM technique can be achieved for the management of large esophageal diverticulum and is safe and effective.

Anatomy of peripancreatic arteries and pancreaticoduodenal arterial arcades in the human pancreas: a cadaveric study.

INTRODUCTION: The purpose of this work was to evaluate the arteries supplying the pancreaticoduodenal (PD) complex. MATERIALS AND METHODS: The study was conducted on 15 fresh enbloc pancreatic specimens by latex injection method which enabled the visualization of the peripancreatic arteries and their minute branches. RESULTS: The gastroduodenal (GDA), anterior superior pancreaticoduodenal (ASPD), and anterior inferior pancreaticoduodenal (AIPD) artery was found in all the cases, whereas the posterior superior pancreaticoduodenal (PSPD) and posterior inferior pancreaticoduodenal (PIPD) artery was present in 93.34% cases. The ASPD artery originated from GDA in all the cases. Two types of variations were observed in the origin of PSPD artery and four types each in the origin of AIPD and PIPD artery. Anatomical and numerical variations were observed in both anterior and posterior arches, posterior arch being absent in 20% cases. CONCLUSIONS: In the present study, an attempt was made to systematically describe the individual arterial configurations of the PD complex. The information provided here has important implications for preoperative planning of technically challenging surgeries and interventions around the pancreatic head.

Anatomy of the hepatic arteries and their extrahepatic branches in the human liver: A cadaveric study.

BACKGROUND: To describe the hepatic arterial anatomy in detail, tracing the individual hepatic arteries from their origin, extrahepatic course, branching to their segmental territorial supply as applicable to the vascular mapping for hepatic endovascular procedures. METHODS: The study was conducted on 100 formalin fixed adult cadaveric livers. The hepatic arterial anatomy was dissected from the origin of hepatic arteries up to their segmental branching. RESULTS: The origin of hepatic arteries was standard in 72% and aberrant in 28% livers. In livers with standard origin, extrahepatic branching of the main hepatic artery was close to the hepatic hilum in 48% and was in the lower part of the hepatoduodenal ligament in 24% livers. The pattern of extrahepatic branching in each type was three and five respectively. Aberrant arterial anatomy was broadly categorized into three groups. The mapping of segmental arterial vascularization of individual hepatic arteries in each type was also done. CONCLUSIONS: In the present study, an attempt was made to systematically describe the complex hepatic arterial anatomy in a clinically applicable fashion. High variability was seen in the hepatic arterial anatomy at each level, a lot of which could not be included in the current classification systems. The information provided is an important prerequisite for performing accurate intra-arterial hepatic interventions.

Risk Factors for Acquiring Scrub Typhus among Children in Deoria and Gorakhpur Districts, Uttar Pradesh, India, 2017.

Scrub typhus is associated with outbreaks of acute encephalitis syndrome in Uttar Pradesh, India. A case-control study indicated that children residing, playing, or visiting fields; living with firewood stored indoors; handling cattle fodder; and practicing open defecation were at increased risk for scrub typhus. Communication messages should focus on changing these behaviors.

Hydroalcoholic extract of cyperus rotundus ameliorates H2O2-induced human neuronal cell damage via its anti-oxidative and anti-apoptotic machinery.

Hydrogen peroxide (H(2)O(2)), a major reactive oxygen species produced during oxidative stress, has been implicated in the pathophysiology of various neurodegenerative conditions. Cyperus rotundus is a traditional medicinal herb that has recently found applications in food and confectionary industries. In the current study, the neuroprotective effects of Cyperus rotundus rhizome extract (CRE) through its antioxidant and anti-apoptotic machinery to attenuate H(2)O(2)-induced cell damage on human neuroblastoma SH-SY5Y cells have been explored. The results obtained demonstrate that pretreatment of cells with CRE for 2 h before administration of H(2)O(2) for 24 h ameliorates the cytotoxicity induced by H(2)O(2) as evidenced by MTT and LDH assays. CRE exhibited potent antioxidant activity by regulating the enzymes/proteins levels such as SOD, CAT, GPx, GR, HSP-70, Caspase-3, and Bcl-2. The pretreatment restored H(2)O(2)-induced cellular, nuclear, and mitochondrial morphologies as well as increased the expression of Brain derived nerve growth factor (BDNF). The anti-oxidant and anti-apoptotic potentials of the plant extract may account for its high content of phenolics, flavonoids, and other active principles. Taken together, our findings suggest that CRE might be developed as an agent for neurodegeneration prevention or therapy.
