Unusual Histological Findings of the Appendix Following Appendectomy; a Ten Year Histopathologic Study

Lesions of the appendix are common. The appendix is however exposed to other uncommon but deleterious lesions which if not detected early and prompt attention given immediately; may result in morbidity and mortality.Materials and methods This was a retrospective study which involved 1171 respondents aged between 2 and 80 years. Demographic data were obtained from the archives of the histopathology department of University of Benin Teaching Hospital. Results were analysed with chi square test and results presented in frequencies tables.Results A total of 1171 samples were analysed out of which 17 were miscellaneous findings. This included 7 diagnosed for chronic granulomatous. Parasitic infestations were observed in only two female and 1 male case respectively and their ages ranged between 21 and 50 years. One case each was seen in Carcinoid; intestinal necrosis; intestinal infarction; chronic HPV; haemorrhagic appendix (which was found in a patient between 70 and 80 year age range).ConclusionsThis study has further emphasised the need for routine histopathologic analysis of all appendices following appendectomies regardless of the macroscopic appearance

Tongue rolling and tongue folding traits in an African population / Rasgos de lengua enrollada y lengua doblada en una población africana

Genetic variations that occur in humans are usually as a result of a plethora of factors which are of enormous value from physical anthropological window especially in studying population variation and human diversity. This study was conducted amongst unrelated volunteer students of Delta State University, Nigeria who were all of Urhobo tribe (71 males) and (72) females aged between 18 years and over to determine their ability to roll or fold the tongues. The frequency of folders (120) and rollers (87) were more common than non-folders (23) and non-rollers (56).The incidence of tongue rolling was higher in females than in their male counterparts. These differences did not however show any statistical significance, p > 0.01. The frequency of R-F was observed to be highest in both males and females (38 and 43) respectively. 22 males and 17 females were observed to be capable of fold but unable to roll their tongue. None rollers and none folders were 9 males and 7 females respectively while rollers and none-folders were the least with frequencies of 2 males and 3 females respectively.

Las variaciones genéticas que ocurren en los seres humanos son, por lo general, resultado de una suma de factores de enorme valor en la antropología física, sobre todo en el estudio de variación de población y diversidad humana. Este estudio se realizó en estudiantes voluntarios no vinculados de la Universidad del Estado de Delta, Nigeria. Todos pertenecientes a la tribu Urhobo, 71 varones y 72 mujeres de 18 y más años de edad. El objetivo del estudio fue determinar su capacidad de plegamiento y enrollamiento lingual. La frecuencia de las lenguas dobladas (120) y enrolladas (87), fue mayor que las no dobladas (23) y no enrolladas (56). La incidencia de la lengua enrollada fue mayor en mujeres. Estas diferencias sin embargo, no fueron estadísticamente significativas, p> 0,01. La frecuencia de RF se observó más alta en hombres y mujeres (38 y 43), respectivamente. 22 hombres y 17 mujeres eran capaces de doblar la lengua pero no de enrollarla. 9 hombres y 7 mujeres no fueron capaces de enrollar la lengua ni de doblarla, mientras que 2 hombres y 3 mujeres fueron capaces de enrollar la lengua pero no de doblarla.
