Morphological Evaluation of Pterygoid Hamulus Through Computed Tomography | Chapter 4 | Medical Science: Recent Advances and Applications Vol. 8

 

The pterygoid hamulus, a small hook-like projection of the sphenoid bone, can be a source of pain in the pharyngeal region. In some cases, it may also cause swelling and discomfort in the palate. Hereby by the authors present a case report of a 38-year-old male presenting with palatal swelling with dull pain in the palatal or oropharyngeal region and mild pain at the site of swelling. He also complained about referred pain to the ear, throat, temporomandibular joint (TMJ), or maxillary region. On palpation, he complained about the tenderness over the hamular region, and intraorally, the hamulus was palpable.

 

A CT scan of the facial skeleton revealed elongation of both the medial and lateral plates of the pterygoid processes. The patient was counselled properly and responded well to the conservative mode of treatment.

Assessment of Molecular Transport OF Chloromethanes through EPDM/PVC Systems | Chapter 9 | Chemical and Materials Sciences - Developments and Innovations Vol. 1

 

A large group of engineering materials of steadily increasing importance in industrial applications is composed of natural and synthetic organic polymers. In recent years, significant progress has been made in many areas of polymer blend and polymer matrix composite science and technology. The examination of the interaction of aliphatic hydrocarbons with macromolecular systems is important for various industrial applications. The transport behavior of EPDM/PVC composites has been studied using the three halogenated hydrocarbons; methylene chloride, chloroform and carbon tetrachloride, which are part of the homologous series of the chloromethanes, as probe  molecules. Peroxide and sulfur were employed to crosslink the matrix. It was investigated how the crosslink density, penetrant type, and crosslinking  system type affected the transport property. Among the chloromethane group, there is a peculiarity that can be observed: sorption increases with  increasing molar volume or the amount of chlorine atoms, as would be expected from basic solubility parameter considerations. The mechanism of transport was found to be deviated slightly from Fickian trend. The differences in the equilibrium uptake can be explained on the basis of morphological changes.

Polymeric Compositions on the Base of Acrylic Acid and Bentonite Clay: Experimental Investigation | Chapter 02 | Challenges and Advances in Chemical Science Vol. 8

 This study looked at the peculiarities of making composition hydrogels (CH) from cross-linked polyacrylic acid (PAAc) and bentonite clay (BC). The crystalline structure of montmorillonite has been disrupted in CHs due to the penetrative of polymeric macromolecules between bundle layers, resulting in a uniform homogenous structure, according to optical microscopy and X-ray diffraction. The kinetics of obtained CH swelling in water were investigated, and it was discovered that they have a high water sorption ability over a wide pH range. The sorption of methylene blue (MB) by gels from aqueous solutions was investigated using the statistical approach. CHs were shown to have a higher sorption capacity than hydrogels on a PAAc basis. Because MB sorption has increased with rising medium temperature, chemisorption has resulted in MB attaching to CHs.

Herniation of Endotracheal Tube Cuff in a Patient with Difficult Airway: A Case Report| Chapter 9 | Highlights on Medicine and Medical Research Vol. 14

 For swellings in the nasopharyngeal and paratracheal regions, a 16-year-old female was referred for a pan endoscopy with multiple biopsies. At the C4 stage, the patient had bilateral tonsil hypertrophy, grade II MPC, two finger mouth opening, and soft tissue swelling compressing the trachea. Following intubation, the patient developed resistance to ventilation and desaturation. The decision was made to remove the tube and hand ventilate the patient. After the tube was removed, it was discovered that the cuff of the tube had herniated towards the upper end of the ETT. The tube was replaced, and the rest of the procedure went smoothly.

Swelling and Drug Release Studies from Hydrophilic Matrices Containing Combination of Different Grades of Hydroxyl Propyl Methylcellulose | Chapter 6 | Trends in Pharmaceutical Research and Development Vol. 5

 In formulating sustained release tablets, polymers are very common and commonly used because they are excellent drug carriers. The current research explores the release of drugs from hydrophilic matrices prepared using a mixture of hydroxyl propyl methylcellulose (HPMC), HPMCK4 M, HPMCK15 M and HPMCK100 M grades. The findings suggest that the concentration and viscosity grades of the polymer were influenced by the swelling and release profiles. The rate of water absorption into the matrices regulates this swelling action of HPMC of different grades in turn. The drug release rate and the matrix-swelling rate have an inverse relationship. This means that the rational combination of the various grades appears to provide a reasonably controlled drug release. Therefore, in predicting drug release, the swelling behaviour is useful.
