Late onset vitiligo and audiological abnormalities: Is there any association?

Background: There is scarce published data on late onset vitiligo. All the studies showing association of audiological abnormalities have been done on younger age group of patients. Aim: To study the clinical characteristics of the patients with late onset vitiligo. Also, to investigate the audiological abnormalities seen in these patients and compare them with age and sex matched healthy volunteers. Methods: One hundred and ninety-seven consecutive patients developing vitiligo after the age of 40 were studied. These patients were examined for the audiological abnormalities, and compared with those seen in age and sex matched healthy volunteers. Results: Vitiligo started between 40 and 50 years of age in 68.02% of our patients. Vitiligo vulgaris was the commonest clinical pattern, and most patients reported onset of their vitiligo on the upper extremities. Fifty four had diabetes mellitus, 19 patients had autoimmune thyroid diseases, and 32 showed hypoacusis on audiometric examination. Eighteen controls (age and sex matched healthy volunteers) also showed hypoacusis. The difference in frequency was not significant (22.37% vs 18%, χ2 - test, P > 0.05). The sensorineural type of audiologic impairment was more commonly seen both in patients as well as in controls. Conclusion: Late onset vitiligo was not found to have statistically significant association with audiological abnormalities in this study

An innovative method to evaluate the suture compliance in sealing the surgical wound lips

Background and aim: The increasing number of surgical procedures performed with local anesthesia, followed by immediate patient discharge from the hospital, emphasizes the need for a tight waterproof suture that is capable of maintaining its tensile strength in the postoperative phase when the wound tumescence, edema due to the anesthetic drug, and surgical trauma disappear. Moreover, the issue of having an accurate surgical wound closure is very relevant in vivo in order to prevent hemorrhage and exogenous microbial infections. This study aimed at designing a new a lab technique that could be used for evaluating the best surgical material. Using such a technique, we compared the wound-lip-sealing properties of three commonly-used suture threads, namely polyurethane, polypropylene, and polyamide. Materials and methods: The mechanical properties of same-size suture threads made from polyurethane, polypropylene, and polyamide, were compared in order to define the one that possess the best elastic properties by being able to counteract the tension-relaxation process in the first 12 hours following surgery. The tension holding capacity of the suture materials was measured in both in vivo and in vitro experiments. The surface area of the scar associated with the three different suture threads was measured and compared, and the permeability of the three different suture threads was assessed at 0 minute, 2 minute, 4 minute, 6 minute, and 8 minute- interval. Results: Results showed that polyurethane suture threads had significantly (P &#60; 0.05) better tensile strength, elongation endurance before breakage, and better elasticity coefficient as compared to polypropylene and polyamide suture threads. Moreover, polyurethane suture threads were significantly (P &#60; 0.05) more impermeable as compared to the other two suture thread types (polypropylene and polyamide). This impermeability was also associated with a tighter wound-lip-sealing ability, and with significantly (P &#60; 0.05) less scar formation. Conclusion: Among the main concerns that surgeons, physicians, and patients often have is the development infection, oozing, and scar at the incision site following suturing. This always raises the question about which suture to use to avoid the above problems. This study provides evidence that the new technique developed in our lab could be used to compare the wound-lip sealing properties of different surgical suture threads. Using such a technique, the results show that polyurethane is significantly better than other commonly-used suture threads, like polypropylene and polyamide, in relation to wound sealing and scar formation.</p

Kimura Disease Manifesting as Synchronous Bilateral Parotid Swelling in a Young Middle-Eastern Patient

Kimura disease is a rare, benign, chronic inflammatory swelling of the subcutaneous tissue, lymph nodes, and glandular tissue. Characteristic features of the disease include, but not limited to, painless subcutaneous head and neck swelling, blood and tissue eosinophilia, and markedly elevated immunoglobulin E (IgE) levels. Herein, we report a rare case of Kimura disease manifesting as synchronous bilateral parotid swelling of 12 years duration in a 33-year-old Middle-Eastern man. To our knowledge only few cases have been reported in the literature involving bilateral parotid glands, and this is the first case to be reported in the Middle East
