Distal humerus Anatomy Egyptians Sexual dimorphism

Authors: AA Hegazy

Journal: International Journal of Advanced Research-2013, 1(9):155-161.

Description:

Determination of sex from the skeleton is of great importance in medicolegal investigations. The available literatures about the dimensions of distal humerus were scanty, especially for Egyptians. This study aimed to establish metric standards for assessment of sex determination from the radiographs as well as to investigate whether bilateral asymmetry exists in the distal humerus. The study included measurements of the distal humerus from 132 (60 males and 72 females) radiographs of normal elbows of 100 adult healthy Egyptian subjects. Thirty-two (16 males and 16 females) of whom were volunteers; and the two humera were radio-graphed. There were statistically significant sex differences in all investigated values, except the trochlear inclination angle. Also, there was symmetry in measurements of the right and left humera in the volunteers. It was concluded that the distal humerus is an effective bone for the estimation of sex even in a fragmentary state.

Journal: theHealth 2012; 3(1): 24-30

Description:

Background: The aim of this article was to evaluate the proposed benefits and consequences of male circumcision and highlight the penile prepuce, the poorly understood and much controversial part of the human body.Methods: Databases of Pubmed, Science Direct, Springer Link, Wiley Interscience and others were searched. The research papers were studied and discussed. Finally, the opinion of the authors was recorded.Results: Male circumcision is a legacy of the human civilization, originating in Egypt. It confers many prophylactic benefits for the recipient and his female partner. The benefits include protection against urinary tract infections, sexually transmitted diseases including HIV, penile and prostate cancer and cervical cancer in the female partner. At the same time, it is a simple and safe procedure, having minimal risks. The removed prepuce is not a vestigial but an important and unique structure, being used in repair of the common malformations of the penile urethra.Conclusion: Benefits of circumcision vastly outweigh its potential risks. Newborns with penile anomalies are best treated by deferring the procedure until the defect can be corrected using prepuce at few months of age.

Description:

In this study, the angle was examined radiologically in an attempt to determine its measurements in adults using a simple method. Antero-posterior plain X-ray views of the normal elbow region were taken in the Radio-Diagnostic Department of Al-Majma'ah, King Khalid Hospital, KSA. The study included 90 cases (45 males and 45 females). Measurement of the carrying angle was done to be confined to the lower third of the humerus and the upper third of the forearm to exclude any interference due to extensions of shaft of the long bones of the elbow in the actual values of the angle. The study demonstrated that the carrying angle is significantly greater in females than in males. In males, it ranged from 5° to 17° with a mean of 9.29±2.98°, while in females it ranged from 10° to 27° with a mean of 18.47±4.12°. The revealed differences between the carrying angles in males and females can be considered as a secondary sex character. The recorded measurements also might be helpful in the management of disorders of the elbow and in its reconstruction after fractures. Furthermore, the proposed method in this study is simple, easy and more or less accurate as it measures the actual angulations at the elbow.

Anatomical Variations of the Human Nasal Osteomeatal Complex, Studied by CT

Anatomical variations. Computed tomography Osteomeatal complex Anatomy

Authors: MO Alsubael, AAM Hegazy

Journal: Zagazig University Medical journal, Special Issue, for 16th Zagazig Annual Conference, 72-83, March

Description:

Background: Precise information of the anatomical variants of the osteomeatal complex is critical for clinicians, especially with the advent of functional endoscopic sinus surgery. This study aimed to determine the incidence and morphology of these variations in adult Saudi patients, using computed tomography (CT). Methods: The anatomical variations of the osteomeatal complex were studied in one hundred adult Saudi patients with clinical suspicion of sinusitis, using oblique CT scan. They were explored in the radio-diagnostic department of Al-Majma'ah, King Khalid Hospital, K.S.A. Results: There was a great number of variations in the anatomy of studied part of the nasal region. Deviated nasal septum was the most common type of variations (78%), followed by pneumatized middle concha (38%). These variations were frequently accompanied with reduction of the osteomeatal complex. Conclusions: Oblique CT scan is a good method to evaluate the osteomeatal complex. This region shows a wide prevalence of anatomical variations. Determination of these variations aids in providing a better surgical orientation and avoiding or minimizing the possible complications.

A MORPHOLOGICAL STUDY OF THE SACRAL HIATUS

SACRAL HIATUS Anesthesia Anatomy Anatomical Variations

Authors: A Hegazy, N Gamil

Journal: Zagazig University Medical Journal, Vol. XII, No.3 July. , Pp. 2877- 86, 2006.

Description:

Background: Anatomical determination of the sacral hiatus is very important for performing successful caudal block. This study investigated its morphological aspects, especially in relation to easily identified bony landmarks. Materials and Methods: Thirteen cadavers of adults of both sexes, as well as ninety dry sacra were used in this study. The region of the sacral hiatus was dissected and examined. The equilateral triangle between the two posterior superior iliac spines and the sacral hiatus was evaluated in both sexes. Also dry sacra were examined for the shape of the sacral hiatus and the level of its apex and base in relation to sacral pieces. Results: Three surface depressions were noticed on the lower part of the back of human body. They formed an equilateral triangle. Its base was formed by the upper two depressions that represented the two posterior superior iliac spines. Its apex was directed below and pointed to the sacral hiatus. In males it nearly pointed to the apex of the hiatus, while in females it descended slightly inside the hiatus. The hiatus was found to lie on one side of the upper limit of the natal cleft. It was roughly triangular in shape. Its apex was directed upwards. Its extent was variable. It varied from the second sacral piece to the lower part of the fifth sacral one. However, the base lied opposite the fifth sacral piece, and was bounded by the two sacral cornua. The hiatus was roofed posteriorly by the sacrococcygeal ligament. It contained the filum terminale and the last two pairs of spinal nerves "fifth sacral and coccygeal nerves". Conclusion: The present study has concluded that the sacral hiatus does not correspond typically to the natal cleft, but it lies on one side of its upper limit. The equilateral triangle could be useful

An Anatomical Study of the Cephalic Vein in The Forearm

Cephalic Vein Forearm Anatomy Clinical

Authors: AAM Hegazy

Journal: New Egyptian Medical Journal, Vol. 35, No. 2, 585-592, August, 2006

Description:

The purpose of the present study was to throw more light on the anatomy of the cephalic vein in the forearm, especially in relation to easily identified landmarks. This may facilitate its use in cases of venous cut-down procedures. Dissection was performed on eighteen cadaveric specimens of human upper limbs in both sexes. The vein was found to begin from the radial end of the dorsal venous network of the hand. It lied in the superficial fascia, ascending on the lateral side of the of forearm to the arm. Thorough its course, the only part related to bony prominence was that lying on the lateral side of the distal end of the radius. Its position was behind the anterior edge of the distal end of radius. This might be an anatomical basis to use this vein as an alternative to the great saphenous vein in cases that need surgical venous cut-down, when the superficial veins are not visible as in state of shock. Superficial radial vein was found on the medial side of the cephalic vein on the dorsum of the hand. Recognition of this consistent location to the vein facilitates its surgical exposure. This helps in localization of the vein through a limited incision, with uncomplicated and favorable outcome.

MORPHOLOGICAL STUDY OF THE ANTEROMEDIAL REGION OF THE ANKLE (ANATOMICAL SNUFF-BOX OF THE ANKLE!)

Anatomy Ankle ANATOMICAL SNUFF-BOX

Authors: AA Hegazy, M Hailal

Journal: New Egyptian Medical Journal, Vol. 32, No. 6, 284-287, June 2005

Description:

The purpose of the present study was to describe the morphological aspects of the antero-medial side of the ankle region, that was similar to the anatomical snuffbox on the lateral side of the dorsum of the wrist. Dissection of this region was performed on twenty-two adult human cadaveric specimens of the ankles in both sexes. This region appeared as triangular skin depression on full extension of the big toe and inversion of the foot. Its base was formed by the anteroinferior end of the medial malleolus and bounded by the tendons of tibial muscles; tibialis anterior anterosuperiorly and tibialis posterior postero-inferiorly. The roof was formed by the skin and fasciae. Great saphenous vein and saphenous nerve were found in the superficial fascia, crossing the triangle medial and superficial to tibialis anterior. The floor was formed by the deltoid ligament of the ankle joint. This ligament appeared strong. However, the most thickened band was that attached to the sustentaculum tali. The presented anatomy provides a basis for a relatively safe area for a needle puncture or surgical approach of the ankle joint
