Abstract Persistent urogenital sinus (PUGS) is an uncommon developmental cloacal anomaly, with Incidence of 0.6 in 10000 female births. Herein we depict the case of a 22-year of age lady who presented with Infertility for 16 months with dyspareunia and was found to have Persistent urogenital sinus associated with other urogenital anomalies as unilateral rudimentary horn with ipsilateral renal agenesis and contralateral dermoid cyst. The patient was successfully treated with the excision of the sinus, the rudimentary horn and the dermoid cyst.

Resumen El seno urogenital persistente (PUGS) es una anomalía cloacal del desarrollo poco común, con una incidencia de 0,6 en 10000 nacimientos de mujeres. Aquí representamos el caso de una señora de 22 años que presentó Infertilidad durante 16 meses con dispareunia y se encontró que tenía seno urogenital persistente asociado con otras anomalías urogenitales como cuerno rudimentario unilateral con agenesia renal ipsilateral y quiste dermoide contralateral. El paciente fue tratado con éxito con la escisión del seno, el cuerno rudimentario y el quiste dermoide.

ABSTRACT Red seaweed possess various sulfated polysaccharides (SPs) that could potentially be exploited as bioactive agents for medical and industrial applications. Crude polysaccharides from the red algae Corallina officinalis (SP1) and Pterocladia capillacea (SP2) were extracted and characterized according to their chemical content and their antioxidant, anti-inflammatory, anticoagulant, antibacterial, antifungal, and antifouling activities. The isolated polysaccharides contained low levels of protein and high levels of carbohydrate and sulfate. The extracted SPs were characterized by Fourier-transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectral data and revealed that SP1 is composed of carrageenan, while SP2 is composed of polysaccharides containing sulfated galactans plus κ- and ι-carrageenan. Both isolated SPs exhibited all the tested biological activities but those of SP2 were superior. These results reflect the beneficial effects that red algal polysaccharides have as a natural renewable bio-product and that there is a significant relationship between polysaccharide structure, sulfate content and their biological properties. Further studies should be undertaken on the fractionation and characterization of polysaccharides extracted from species of red seaweed in addition to experiments to verify the efficiency of the extracted SPs for food and medical uses in vivo.

Abstract Introduction Preoperative temporal bone imaging studies have been routinely performed prior to cochlear implantation. Radiologists need to report these examinations with special focus on the surgeon’s expectations. Objectives To provide a basic structured format, in the form of a checklist, for reporting preoperative computed tomography (CT) and to its clinical impact on operative findings. Methods The preoperative temporal bone CT scans of 47 patients were analyzed and reported according to the proposed checklist. Intraoperative assessment of mastoidectomy, posterior tympanotomy and round window access was done by the surgeon in a blinded fashion and were correlated with the radiological findings to assess its significance. Results The proposed radiological checklist was reliable in assessing operative difficulty during cochlear implantation. Contracted mastoid and lower tegmen position were associated with a greater difficulty of the cortical mastoidectomy. Presence of an air cell around the facial nerve (FN) was predictive of easier facial recess access exposure. Facial nerve location and posterior external auditory canal (EAC) wall inclination were predictive of difficult round window (RW) accessibility. Conclusion Certain parameters on the preoperative temporal bone CT scan may be useful in predicting potential difficulties encountered during the key steps involved in cochlear implant surgery.
