Introduction: There are twelve cranial nerves and seventh one is the Facial cranial nerve, which supplies the muscles of facial expression. It gives of five terminal branches, which form a plexus with in the parotid gland. These branches exhibit variations in their branching pattern. Detection of the main trunk of facial nerve and its branches is important in all surgeries of this area, to avoid any injury that may lead to the loss of function of this nerve. This study has elaborated the branching and communications among the terminal branches of facial nerve in parotid gland. Objectives: To study the anatomical variations in the terminal branching and communicating pattern of the seventh cranial nerve and to observe the division pattern of the facial nerve trunk in parotid area. Study Design: It was carried out at Department of Forensics and Department of Anatomy in King Edward Medical University Lahore. Period: The study commenced in March 2014 after approval of the synopsis by the Advance Studies and Research Board of KEMU and was successfully completed in December 2015. Methodology: Dissection of one hundred hemi-faces in the Departments of Forensic and Anatomy at King Edward Medical University Lahore. Adult cadavers of both sexes were included and with mutilated face were excluded. A Descriptive Cross-sectional type of study. Collected data was analyzed in SPSS 13. Simple frequency/percentages tables and charts were used to presents the outputs. Chi-Square, Student t-test and ANOVA were used. Results: Branching and Communicating Pattern according to occurrence were: Type I, 9%, Type II, 39%, Type III, 20%, Type IV, 25%, Type V, 6%, Type VI, 1%. 95% cases showed bifurcation. Conclusion: Most common branching pattern was Type II (39%), and least common was Type VI (1%). Surgery of Zygomatic region must be done carefully due to complexity of branching in this area.
Urinary tract infection (UTI) is one of the most common infections in the Pakistani local population that afflicts people and if not treated properly and timely could cause serious damages to the urinary tract. Nowadays increasing antibiotic resistance is one of the problems in managing UTI to check the metal resistance of this disease causing organisms. Urine specimens of in-patients and out-patients in Sheikh Zayed Hospital, Lahore were cultured on blood agar and eosin methylene blue agar (EMB). Isolated bacteria were identified according to standard microbiological tests and then subjected to sensitivity testing according to routine method of disk agar diffusion technique and metal resistance on media containing metal salts. Our findings suggest that there is a method to treat the UTI by antibiotics but nowadays antibiotic resistance is increasing day by day. Results of the present study underline the need for sensitivity tests prior to antibiotic therapy in UTI, which could help and guide in proper choosing of antibiotics and effective treatment and therefore prevention of antibiotic resistance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
