Congenitally Missing

Prosthodontists usually stick to the dictum by MM Devan, “preservation of what remains than meticulous replacement of what has been lost.1” “Microtia” is a term used to describe congenital anomaly of the external ear. It is a combination of the words “micro” and “otia” each of the term denoting small and ear respectively. It includes a range of deformities which may consist of presence of a rudimentary ear, a grossly normal or smaller ear or complete absence of the entire external ear. These deformities usually account for 3 in every ten thousand births, with less than 10 % of all the cases showing bilaterally missing ears.2-4 Facial deformities are common for the microtia patient as the auricle develops from tissues of the branchial arches. Figure 1 describes the patient having congenitally missing unilateral ear. Maxillofacial prosthodontics deals with prosthetic rehabilitation of disfigured or missing parts of head and neck. Prosthetic replacement of the exterior part (Epithesis) can be related to as old as civilization. References to it are available in Indian, Greek, Roman, Egyptian Civilizations.5 Ambroise Pare is credited with making various contributions to the materials and techniques in facial prosthetics. Fabrication of an extra-oral prosthesis is probably more of an art than science. Throughout the recorded history, humans have attempted to restore missing parts of the body by using various artificial materials. MPF materials have evolved since centuries right from metals, ivory, porcelain, waxes, natural rubber, gelatin, and latex to modern day materials such as methacrylate or acrylic resins, polyurethane elastomers, and silicone elastomers each having their own set of advantages and disadvantages. But silicone is most commonly used because of its assorted benefits over other MFP materials. This case report describes an auricular prosthesis for the patient with congenital ear deformity using an acrylic template for colour depiction and room temperature volcanizing (RTV) silicone.6

Tuberculosis (TB) can infect any part of the body. Preauricular sinus is a congenital anomaly of the external ear. Infection of the preauricularsinus is mainly caused by bacteria. This is a case report of TB of preauricular abscess which presented with an unresponsive abscess to an antibiotic. TB of preauricular abscess is extremely rare, and assumed to have the same etiology as cutaneous tuberculosis. Treatments are standard anti-TB drugs with excision of preauricular sinus. This case emphasizes the consideration of TB in a preauricular abscess that does not respond toantibiotics, incision and drainage.

By the modification of solid-lipid nanoparticles (SLNs), the nano-structured lipid carriers (NLCs) were obtained by the modification of nanostructured that hold the qualities of the SLN, increases the stability of the drug, and prevents drug leakage. The limitations of the drugs that are delivered in the body using different routes are poor solvency, first pass metabolism, and poor bioavailability hence to overcome these limitations NLCs were prepared. Oral, topical, transdermal, ocular, and parenteral are the different routes through which nanobased systems are delivered. Spatially incompatible liquid lipids and solid lipids are blended and NLCs were prepared. It stays solid at room temperature. The advantages of for drug therapy over conventional carriers NLCs are increased solubility, improved bioavailability. This review describes about the NLC, its advantages and disadvantages, types, NLC techniques, mode of action, and applications of NLC. Imperfect, amorphous, and multiple types are the main three types of NLCs. Lipids, liquid lipids, solid lipids, Emulsifiers, ultraviolet (UV) blockers, and aqueous medium were the excipients used. Microemulsion technique, microemulsion based SLN/NLC preparations, solvent diffusion method, high-pressure homogenization (HPH), hot and cold homogenization techniques, and melt emulsification method are the techniques used for the preparation of NLC. The applications of NLCs are for ocular, brain targeting, topical, cancer therapy, cosmetics, and analgesia.

The atomic force microscope (AFM) is capable of imaging electrically conductive and non-conductive surfaces at atomic resolution. When used to image biological samples, however, lateral resolution is often limited to nanometer levels, due primarily to AFM tip/sample interactions. Several approaches to immobilize and stabilize soft or flexible molecules for AFM have been examined, notably, tethering coating, and freezing. Although each approach has its advantages and disadvantages, rapid freezing techniques have the special advantage of avoiding chemical perturbation, and minimizing physical disruption of the sample. Scanning with an AFM at cryogenic temperatures has the potential to image frozen biomolecules at high resolution. We have constructed a force microscope capable of operating immersed in liquid n-pentane and have tested its performance at room temperature with carbon and metal-coated samples, and at 143° K with uncoated ferritin and purple membrane (PM).

Постоянно растущий интерес к разработке новых неинвазивных и безманжетных методов измерения параметров сердечной деятельности, использование которых давало бы возможность непрерывного и удаленного контроля сердечно-сосудистой системы, обуславливает актуальность данной работы. В многочисленных публикациях продолжаются обсуждения преимуществ и недостатков различных методов ранней диагностики сердечно-сосудистых заболеваний. Однако артефакты движения являются сильной помехой, мешающей точной оценке показателей функционирования сердечно-сосудистой системы. Одним из перспективных методов контроля является метод оценки физиологических параметров с использованием фотоплетизмографии. Данная статья посвящена разработке устройства для фотоплетизмографических исследований и алгоритмических методов обработки регистрируемых сигналов для обеспечения мониторинга сердечного ритма с заданной точностью. В работе используются технологии цифровой адаптивной фильтрации полученных сигналов для мониторинга сердечного ритма в условиях внешних механических и электрических помеховых воздействий, ухудшающих точностные характеристики системы, а также разработана архитектура системы и изготовлен макет устройства, который позволил провести измерения для определения оптимального алгоритма цифровой обработки сигналов. При использовании устройства применялись методы адаптивной фильтрации на основе фильтров Винера, фильтров на основе метода наименьших квадратов и Калмановской фильтрации. Разработанное устройство для фотоплетизмографических исследований обеспечило возможность мониторинга сердечного ритма с заданной точностью, контроля текущего состояния организма и может быть использовано в качестве средства диагностики заболеваний сердца The constantly growing interest in the development of new non-invasive and cuff-free methods for measuring the parameters of cardiac activity, the use of which would give the possibility of continuous and remote monitoring of the cardiovascular system, determines the relevance of this work. Numerous publications continue to discuss the advantages and disadvantages of various methods of early diagnosis of cardiovascular disease. However, motion artifacts are a strong hindrance to the accurate assessment of the performance of the cardiovascular system. One of the promising control methods is the method for assessing physiological parameters using photoplethysmography. This article is devoted to the development of a device for photoplethysmographic studies and algorithmic methods for processing recorded signals to ensure monitoring of the heart rate with a given accuracy. The work uses technologies of digital adaptive filtering of the received signals to monitor the heart rate in conditions of external mechanical and electrical interference, which worsen the accuracy characteristics of the system, as well as the architecture of the system and a prototype of the device, which made it possible to carry out measurements to determine the optimal algorithm for digital signal processing. When using the device, the methods of adaptive filtering based on Wiener filters, filters based on the least squares method and Kalman filtering were used. The developed device for photoplethysmographic studies provided the ability to monitor the heart rate with a given accuracy, control the current state of the body and can be used as a means of diagnosing heart diseases

Epistaxis in children is one of the important presenting symptoms for attending emergency department in paediatric patients. Recurrent epistaxis is common in children. Although epistaxis in children usually occurred due to different benign conditions, it may be one of the important presenting symptoms of some inherited bleeding disorder. Whereas most bleeding disorders can be diagnosed through different standard hematologic assessments, diagnosing rare platelet function disorders may be challenging. In this article we describe one case report of platelet function disorders on Glanzmann’s thrombasthenia (GT). Our patient was a 10-year old girl who presented to us with history of recurrent severe epistaxis. She had a bruise on her abdomen and many scattered petechiae in different parts of the body. Her previous investigations revealed no demonstrable haemostatic anomalies. After performing platelet aggregation test, she was diagnosed as GT.

Rationale: Linezolid (LNZ) induced Cutaneous Adverse Drug Reactions (CADRs) have rare atypical presentation. Till date, there are very few published case reports on LNZ induced CADRs among the multidrug-resistant patients suffering from Infective Endocarditis (MDR IE). Here, we present a rare case report of LNZ induced CARs in a MDR IE patient. Case report: A 24-year-old female patient was admitted to the hospital with chief complaints of fever (101°C) associated with rigors, chills, and shortness of breath (grade IV) for the past 4 days. She was diagnosed with MDR IE, having a prior history of rheumatic heart disease. She was prescribed LNZ 600mg IV BD for MDR IE, against Staphylococcus coagulase-negative. The patient experienced flares of cutaneous reactions with multiple hyper-pigmented maculopapular lesions all over the body after one week of LNZ therapy. Upon causality assessment, she was found to be suffering from LNZ induced CADRs. LNZ dose was tapered gradually and discontinued. The patient was prescribed corticosteroids along with other supportive care. Her reactions completely subsided and infection got controlled following 1 month of therapy. Conclusion: Healthcare professionals should be vigilant for rare CADRs, while monitoring the patients on LNZ therapy especially in MDR patients as they are exposed to multiple drugs. Moreover, strengthened spontaneous reporting is required for better quantification.

Congenitally Missing

Introduction: Maxillary canines play strategic roles in maintaining the normal function and visibility of teeth. However, rare cases of bilateral permanent congenitally missing maxillary canines were occurring. Replacing these missing canines with dental implant prostheses is an optimal treatment plan for aesthetics and functions. Case Report: In this case report, we described the replacement of bilateral maxillary canines with osseointegrated implants to support all-ceramic prostheses for a young female patient. This treatment avoids the conventional preparation of adjacent teeth as a part of prosthetic reconstructions. In addition to that, all-ceramic crowns are biocompatible with oral cavity structures. Conclusion: The stable short-term result has been achieved with the replacement of the bilateral congenitally missed canines with an implant and cemented all-ceramic crowns, with 3-years cumulative success rate.

Lower Back

Gridhrasi (Sciatica) is a disorder in which low back pain is found, that spreads through the hip, to the back of the thigh and down the inside of the leg. Mechanical low back pain (LBP) remains the second most common symptom related reason for seeing a physician. 85% of total population will experience an episode of mechanical LBP at some point during their lifetime. Fortunately, the LBP resolves for the vast majority within 2-4 weeks. There are many causes for low back pain, however true sciatica is a symptom of inflammation or compression of the sciatica nerve. The sciatica nerve carries impulses between nerve roots in the lower back and the muscles and nerve of the buttocks, thighs and lower legs. Compression of a nerve root often occurs as a result of damage to one of the discs between the vertebrae. In some cases, sciatic pain radiate from other nerves in the body. This is called referred pain. Pain associated with sciatica often is severe, sharp and shooting. It may be accompanied by other symptom, such as numbness, tingling, weakness and sensitivity to touch. There is only conservative treatment giving short term relief in pain or surgical intervention with side effect. But these are not successful and therefore those who are suffering from this are always in search of result oriented remedy. Walking distance and SLR test were taken for assessment parameter, VAS score was adopted for pain. Before treatment patient was not able to walk even 4 to 5 steps due to severe pain, was brought on stretcher and his SLR was 30° of right side. After 22 days of treatment he was able to walk up to 500 meters without any difficulty, SLR was changed to 60° and patient had got 80 % relief in pain. This case report showed that Ayurvedic protocol is potent and safe in the treatment of Gridhrasi.
