Pseudocyst of the auricle is a condition where spontaneous serous fluid collection is seen on the lateral surface of the pinna. The aetiology of this condition is not known. Several methods of treatment have been advocated in the past. We report 10 cases of unilateral pseudocyst who were treated with aspiration and pressure dressing by a plaster of Paris cast over the pinna for two weeks.

<p class="abstract"><strong>Background:</strong> The introduction of the operating microscope has significantly enhanced the outcome of tympanoplasty by improving the accuracy of the technique. The operating microscopy provides a magnified image in straight line; hence the surgeon can’t visualize the deep recesses of the middle ear in single operating field. This is overcome by use of rigid endoscope for tympanoplasty. In rigid endoscopy view is better but surgeons 2 hands are not free so manipulation here is difficult.</p><p class="abstract"><strong>Methods:</strong> 30 cases of safe CSOM from each group viz microscopic assisted (MES) &amp; endoscopic assisted (EES) were selected operated by full cuff (superiorly based tympanomeatal flap technique) and compared for graft uptake, hearing improvement &amp; complications.</p><p class="abstract"><strong>Results:</strong> Graft uptake rate was 93.33% in both groups. In our study the pre operative mean air bone gap of the patients was 37.23+5.79 db after surgery at 6 months came down to 17.17+3.31 db hence after calculating the mean air bone gap closure it came down to be 20.4+4.85. Which showed a significant improvement in the hearing (p value 1.493E-23 which is less than 0.05). 6.67% cases from both groups showed failure of graft uptake.</p><p><strong>Conclusions:</strong> The graft uptake, hearing improvement, Complications produced by each of the techniques in large, subtotal, and anterior moderate perforations by each technique is comparable i.e. both techniques have same results.</p>

In this article a medicinal oil (neem oil) is fractionated and compared with original oil. The fractions were separated at low temperature using chloroform and methanol. The uniphase mixture of solvents and neem oil at room temperature was transformed to a bi-phasic system at low temperature. The isolated fractions (NOC – isolated using chloroform; NOM – isolated using methanol) were characterized and differentiated by GC, FT-IR and Rheometer. GC and FTIR have well revealed the difference in composition of fatty acids in fractions – NOC; NOM and neem oil (NO). Rheologically all the oils are different in viscosity from parent oil. The NOM fraction of neem oil showed newtonian behavior while NOC shows a non-newtonian behavior. It can be concluded from data that fractions NOC, NOM can be used for targeting drugs using various formulation approaches.
