Significance of Correct Diagnosis of Odontogenic Extraoral Sinus: A Report Of Two Cases

Cutaneous draining sinus tracts of odontogenic origin often are a diagnostic challenge. A delay in correctly diagnosing these types of lesions can result in unnecessary antibiotic therapy and surgical treatment. This case report presents the clinical course of two cases with extra-oral sinus tract formation, from diagnosis and treatment to short-term follow-up and evaluation. These facial lesions were initially misdiagnosed as lesions of non-odontogenic origin. Later on an odontogenic cause was identified and endodontic intervention resulted in resolution of the problem, confirming the initial misdiagnosis

AN OBSERVATIONAL STUDY OF DOSHA AND DUSHYA IN THE MANIFESTATION OF VATAKANTAKA

The health of the human body depends on the equilibrium state of Dosha, Dhatu and Mala. Knowledge of disturbance in equilibrium of the Dosha and Dushya helps us to know the diagnosis, prognosis and treatment of the disease.The term “Vatakantaka” denotes a disease of Vata in which the pain is experienced at heel by the patient. Even though Vatakantaka has been mentioned under Vatavyadhi, the Samprapti Ghatakas and detailed pathogenesis is not available in any classical text. Such details are essential for proper planning of treatment.This study is intended to assess the Dosha and Dushya that are involved in the manifestation of Vatakantaka.30 individuals were diagnosed as Vatakantaka were taken for the study. The Dosha and Dushya assessment were done with the help of questioner. The statistical analysis shows involvement of Vata Dosha and Asthi Dhatu in the pathogenesis of Vatakantaka

Utility of Coronoid Bone Graft in Residual Deformity of Zygomaticomaxillary Complex and Associated Orbital Fractures: In Central India Population

This article reports 20 cases elaborating the role of mandibular coronoid process as a graft in reconstruction of small continuity defects of residual or old zygomaticomaxillary complex (ZMC) fractures or the orbital floor fractures associated ZMC fractures. Though different other various autogenous and alloplastic materials are available, coronoid has its own advantages. The most important advantage of using coronoid graft is autogenous bone of intramembranous origin harvested through the same surgical site. Various authors for small continuity defects have documented its use as a graft. All the cases in this report showed acceptable results. Thus, we recommend the use of coronoid process of the mandible as a source for autogenous bone graft as it can provide sufficient bone in quantity and quality for selected maxillofacial reconstructions

Surface acoustic wave stimulated Brillouin scattering in thin-film lithium niobate waveguides

We report the first-ever experimental observation of backward stimulated Brillouin scattering (SBS) in thin-film lithium niobate (TFLN) waveguides. The peak Brillouin gain coefficient of the z-cut LN waveguide with a crystal rotation angle of 20$^{\circ}$ is as high as 84.9m$^{-1}$W$^{-1}$, facilitated by surface acoustic waves (SAW) at 8.06GHz

Inclusion of carbohydrate antigen 242 in addition to carbohydrate antigen 19.9 in serological workup of carcinoma gall bladder: a case series analysis

Background: Common antigenic pool is seen because of shared embryonic origins of gall bladder cancer (GBC) and pancreas. Hence, we analyzed the role of serum carbohydrate antigen 242 (CA242) which has been studied in pancreatic cancer, in GBC. The objectives were to identify whether serum CA242 provides added advantage in diagnosis of GBC when compared to controls and to determine its cut-off value. Methods: Serum CA 19-9 level was determined by chemiluminescent micro particle assay and CA242 by enzyme linked immunosorbent assay (ELISA) of age matched cases and controls. Results: Total enrolled patients were 83 including 10 (11.7%) healthy volunteers, 22 (25.9%) chronic cholecystitis cases, and 53 (62.4%) patients with histological evidence of carcinoma. Mean age of presentation of GBC was 51.64 SD10.88 years with F: M ratio of 5.6:1. Pain (90.6%, 48/53) accompanied with jaundice was significantly associated with GBC well reflected by significantly raised serum total bilirubin (p=0.011), direct bilirubin (p=0.008) along with alkaline phosphatase levels (p=0.001). Significantly higher median value of CA 19-9 and CA242 was observed in GBC when compared to CC and healthy volunteers (p<0.001) with a significant correlation between tumor size (>2.5 cm) and serum levels of CA242. The best cut-off limit for CA242 was 45.25 IU/ml. The specificity for carcinoma diagnosis increased to 100% when CA242 was included along with CA 19.9 in serological estimation. Conclusions: We recommend that CA antigen 19-9 may be complimented with CA242 for serological identification of malignancy in the gall bladder

Evaluation of coronary arteries in congenital heart disease in children : diagnostic comparison of electrocardiogram-gated and non-electrocardiogram-gated computed tomography cardiac angiograpy

Purpose: To compare the visualization and anatomy of coronary arteries in children (≤ 2 years) with congenital heart disease (CHD) on non-electrocardiogram (ECG)-gated and ECG-gated computed tomography angiography (CTA). Material and methods: In this retrospective study, approved by the Ethics Committee of our institute, evaluation of coronary arteries in CHD was performed in 40 children on non-ECG-gated CTA and in 42 children on ECG-gated CTA. The origin and course of the right coronary artery (RCA), left main coronary artery (LMCA), left anterior descending (LAD) artery, and left circumflex (LCX) artery were evaluated by 2 paediatric radiologists independently. Results: ECG-gated CT scans yielded increased (additional) visualization of all the coronary arteries, when compared to non-ECG-gated CT scans. The RCA, LMCA, LAD artery, and LCX artery were visualized in 47.5%, 62.5%, 55%, and 32.5% of children, respectively, on non-ECG-gated studies, while they were visualized in 64.3%, 92.8%, 80.9%, and 62% children, respectively, on ECG-gated studies. The coronary artery anatomical variations were also supplementarily detected more in the ECG-gated group (23.8%) than in the non-ECG gated group (2.5%). Conclusions: ECG-gated CT cardiac angiography studies yield enhanced diagnostic outcomes for the evaluation of the coronary arteries in comparison to non-ECG-gated studies

A Real-Time Feature Indexing System on Live Video Streams

Most of the existing video storage systems rely on offline processing to support the feature-based indexing on video streams. The feature-based indexing technique provides an effec- tive way for users to search video content through visual features, such as object categories (e.g., cars and persons). However, due to the reliance on offline processing, video streams along with their captured features cannot be searchable immediately after video streams are recorded. According to our investigation, buffering and storing live video steams are more time-consuming than the YOLO v3 object detector. Such observation motivates us to propose a real-time feature indexing (RTFI) system to enable instantaneous feature-based indexing on live video streams after video streams are captured and processed through object detectors. RTFI achieves its real-time goal via incorporating the novel design of metadata structure and data placement, the capability of modern object detector (i.e., YOLO v3), and the deduplication techniques to avoid storing repetitive video content. Notably, RTFI is the first system design for realizing real-time feature-based indexing on live video streams. RTFI is implemented on a Linux server and can improve the system throughput by upto 10.60x, compared with the base system without the proposed design. In addition, RTFI is able to make the video content searchable within 20 milliseconds for 10 live video streams after the video content is received by the proposed system, excluding the network transfer latency

WildSense: Monitoring Interactions among Wild Deer in Harsh Outdoor Environments Using a Delay-Tolerant WSN

Biologists and ecologists often monitor the spread of disease among deer in the wild by using tracking systems that record their movement patterns, locations, and interaction behavior. The existing commercial systems for monitoring wild deer utilize collars with GPS sensors, deployed on captured and rereleased deer. The GPS sensors record location data every few hours, enabling researchers to approximate the interaction behavior of tracked deer with their GPS locations. However, the coarse granularity of periodically recorded GPS location data provides only limited precision for determining deer interaction behavior. We have designed a novel system to monitor wild deer interaction behavior more precisely in harsh wilderness environments. Our system combines the functionalities of both GPS and RF-radio sensors with low-cost and minimal-resource motes. We designed and built our system to be able to operate robustly for a period of up to several months for continual tracking and monitoring of the locations and interaction behaviors of wild deer in harsh environments. We successfully deployed six deer collars on six wild deer that were captured and rereleased in the Soapstone Prairie Natural Area of northern Colorado over a one-month period. In this paper, we describe how we designed and built this system and evaluate its successful operation in a wilderness area

Sphincter saving anorectoplasty (SSARP) for the reconstruction of Anorectal malformations

<p>Abstract</p> <p>Background</p> <p>This report describes a new technique of sphincter saving anorectoplasty (SSARP) for the repair of anorectal malformations (ARM).</p> <p>Methods</p> <p>Twenty six males with high ARM were treated with SSARP. Preoperative localization of the center of the muscle complex is facilitated using real time sonography and computed tomography. A soft guide wire is inserted under image control which serves as the route for final pull through of bowel. The operative technique consists of a subcoccygeal approach to dissect the blind rectal pouch. The separation of the rectum from the fistulous communication followed by pull through of the bowel is performed through the same incision. The skin or the levators in the midline posteriorly are not divided. Postoperative anorectal function as assessed by clinical Wingspread scoring was judged as excellent, good, fair and poor. Older patients were examined for sensations of touch, pain, heat and cold in the circumanal skin and the perineum. Electromyography (EMG) was done to assess preoperative and postoperative integrity of external anal sphincter (EAS).</p> <p>Results</p> <p>The patients were separated in 2 groups. The first group, Group I (n = 10), were newborns in whom SSARP was performed as a primary procedure. The second group, Group II (n = 16), were children who underwent an initial colostomy followed by delayed SSARP. There were no operative complications. The follow up ranged from 4 months to 18 months. Group I patients have symmetric anal contraction to stimulation and strong squeeze on digital rectal examination with an average number of bowel movements per day was 3–5. In group II the rate of excellent and good scores was 81% (13/16). All patients have an appropriate size anus and regular bowel actions. There has been no rectal prolapse, or anal stricture. EAS activity and perineal proprioception were preserved postoperatively. Follow up computed tomogram showed central placement the pull through bowel in between the muscle complex.</p> <p>Conclusion</p> <p>The technique of SSARP allows safe and anatomical reconstruction in a significant proportion of patients with ARM's without the need to divide the levator plate and muscle complex. It preserves all the components contributing to superior faecal continence, and avoids the potential complications associated with the open posterior sagittal approach.</p
