OtItIs externa Otitis externa is an inflammation of the external auditory canal, characterised by erythema and oedema. It has a 12-month period prevalence of 1.3% in females and 1.2% in males.1 Patients typically present with otalgia and an infected discharge. However, there is generally no change in hearing unless the entire canal is obstructed. Movement of the tragus results in significant di...

objectives: microtia is the most commonly seen congenital ear defect, and involves an auricular deformity either unilaterally or bilaterally. the aim of this study was to fabricate silicone prostheses for a child with bilateral microtia using an innovative technique. methods: this method involved the construction of bilateral ear prostheses using clips, which were located within the layers of t...

Removal of fly ash using wet scrubbers is widely used in the small and medium scale industries. Among the wet scrubbing methods, spray column falls into the simplest type category for its simple construction and various advantages. A novel pilot plant wet scrubber has been conceived, designed and fabricated. This paper distinctly focuses on the detailed design and fabrication of the ejector, wh...

Wet friction clutches have become widely used in today’s transmissions, e.g. automatic transmissions, dual clutch transmissions, etc. It is known that the central role of this particular component is strongly determined by its friction characteristics. While a clutch is in use, degradation inevitably takes place that consequently deteriorates its friction characteristics. However, to the author...

recent developments in medicine have given us a better insight into a group of disorders known as autoimmune diseases. in particular, advances have occurred in our understanding of the autoimmune inner ear disease (aied). in this article, the authors review the different postulated theories in the pathogenesis of this disease. the clinical presentation, the available para-clinical diagnostic to...

The present study aimed to determine whether there is excessive mean daily intake of phosphorus in 3- to 5-year-old Japanese children and to ascertain relationships between phosphorus intake and various food and beverage groups. Subjects comprised of 90 children, with 15 boys and 15 girls in each age group from 3 to 5 years. The duplicate-diet technique was used to ascertain total dietary intak...

Many species from Senecio genus have been used in traditional medicine, and their pharmacological activities have been demonstrated. This study investigated the chemical composition and anti-inflammatory activities of essential oils from Senecio flammeus. A total of 48 components representing 98.41 % of the total oils were identified. The main compounds in the oils were α-farnesene (11.26 %), c...

To test an economically reasonable method to reduce thermal stress, we performed an alternated intervention-control study on 2 groups of 8 male steel workers performing the same jobs, using 2 l of water at ambient temperature (23.5 degrees C +/- 1.4), poured on the head and hands. Each group participated for 2 d as control and 2 d as intervention during 4 consecutive summer days in Brazil, 5 h ...

Curcuma longa is widely known for its anti-inflammatory activity in traditional system of medicine for centuries and has been scientifically validated extensively. The present study was conducted to evaluate the anti-inflammatory activity of curcuminoids and oil-free aqueous extract (COFAE) of C. longa and compare it with that of curcuminoids and turmerones (volatile oil), the bioactive compone...
