Our aim was to investigate the variation in the vertebral levels of the origins of the celiac artery, superior and inferior mesenteric arteries, paired renal arteries, and common iliac arteries. We conducted a retrospective imaging study in a large public secondary hospital on a nonrandom sample of 227 participants. We consecutively included adult patients who had undergone computed tomography angiography of the abdomen and excluded patients with a history of any vertebral abnormality or whose images revealed evidence of a vertebral abnormality or a congenital anomaly of any of the branches of the abdominal aorta. The primary outcome was the frequency distribution of the vertebral levels of the landmarks. The secondary outcomes were the intercorrelations of the vertebral levels of the landmarks and their relationships with age, sex, weight, height, and body mass index. The celiac artery originated at T11/T12-L1/L2, followed by the superior mesenteric artery at T12-L2, the paired renal arteries at T12/L1-L2/L3, the inferior mesenteric artery at L2-L4, and the common iliac arteries at L3-L5. The vertebral levels of the landmarks were positively intercorrelated and stronger between proximate pairs. In addition, the vertebral levels of the landmarks were related to age, but not sex, weight, height, or body mass index. The intercorrelations suggest that a considerable proportion of the variation is accounted for by 'trickle-down' variation; variation in the vertebral level of a proximal landmark results in variation in the vertebral level of the immediate distal landmark. The overarching parameter remains unidentified.

The dorsal metacarpal veins are frequently cannulated. Cannulation success is determined by several variable anatomic features. The objective of this study is to classify, for the first time, the anatomic variants of the dorsal metacarpal veins. In this cross-sectional study, 520 university students and staff were conveniently recruited. The dorsal metacarpal veins in 1040 hands were studied. Venous visibility was enhanced by either tourniquet application or near-infrared illumination. Variant patterns of the dorsal metacarpal veins were classified. The final analysis included 726 hands, for an exclusion rate of 30 %. Eight pattern types were identified. Three anatomic features informed the variation. Bilateral symmetry of the dorsal metacarpal veins was present in 352 participants (83 % of the total). The overall frequency distribution of variants in both hands was similar (P = 0.8). The frequency distribution of variants was subject to sexual dimorphism (P = 0.001), ethnic variation (P

En el Departamento de Radiologia del Hospital de la Universidad de Jordania, Amman, Jordania, se llevo a cabo un estudio prospectivo entre el mes de julio de 2001 al mes de julio del 2015. Durante ese periodo se descubrieron cinco casos de vena cava inferior doble (VCID) en una cohorte de 7722 pacientes (3861 hombres y mujeres 3861, de 49,5 ± 16,9 anos, con un rango de edad de 16-78 anos). Los casos fueron diagnosticados por medio de venografia por tomografia computada espiral con contraste (TCV) y confirmados por medio de venografia por estudio tridimensional turbo. La mayoria de los pacientes (3166, 41 %) fueron remitidos para estadificacion y seguimiento de tumores malignos. Se presentaron complicaciones postoperatorias en 1777 pacientes (23 %), dolor abdominal no especificado en 1467 (19 %), evaluacion preoperatoria en 849 (11 %) y traumatismo en 463 pacientes (6 %). La venografia por resonancia magnetica (RMV) mostro una mayor sensibilidad, precision diagnostica, y resultando no invasiva para la evaluacion de la vena cava inferior (VCI). RMV es una modalidad mas util, no invasiva para la evaluacion de la VCI. VCID es una anomalia frecuente, encontrandose en nuestro estudio una incidencia de 0,064 %. Ademas se realizo una revision de la literatura, la embriogenesis, y la importancia de esta anomalia. Tambien, se proporcionaron cifras de muestras de los casos relevantes.

SUMMARY: The foramen magnum is morphometrically typified by two perpendicular diameters and a distinct margin. This important anatomical landmark is subject to high interindividual variation. The objective of this study was to evaluate the dimensions and morphology of the foramen magnum in a Jordanian population. In this retrospective study, 247 individuals were consecutively sampled using the institutional picture archiving and communication system. The anteroposterior and transverse diameters of the foramen magnum were measured; the foramen magnum index was calculated; and, the shape of the foramen magnum was visually assessed. The sex-pooled anteroposterior and transverse diameters were 35.1 ± 3.2 mm and 29.3 ± 2.5 mm, respectively. The sex-pooled foramen magnum index was 1.20 ± 0.10. The diameters were significantly different (P

A 29-year-old man with hypospadias and bilateral undescended testicles presented with recurrent attacks of lower urinary tract infections and painful ejaculation. He was diagnosed to have very large bilateral seminal vesicle stones. The pelvis X-ray showed two radio-densities located in the pelvis with symmetrical appearance while Ultrasound showed them as echogenic structures with posterior acoustic shadowing. In magnetic resonance imaging (MRI) of the pelvis they appeared hypointense in both T1-weighted and T2-weighted images while pelvic computed tomography scan (CT scan) showed bilateral huge stones in the seminal vesicles. The stones were extracted by open surgery through the bladder after transurethral excision of the ejaculatory ducts. Here, we report the first case of bilateral, large, heart-shaped, calcium oxalate monohydrate of seminal vesicle caliculi with brief literature review.

The Effects Of An Aqueous Extract Of Peganum Harmala Seeds On The Smooth Muscles Of Rabbit and Guinea Pig Were Tested In Vitro Using Isolated Segments Of Intestine, Trachea and Aorta. The Extract Inhibited The Spontaneous Movement Of The Rabbit Jejunum and Guinea Pig Ileum and The Contractions Of Rabbit Jejunum and Guinea Pig Ileum Induced By 10−4M Acetylcholine Stimulation. The Extract Also Inhibited The Contractions Of Rabbit Tracheal Smooth Muscle Induced By 10−4M Acetylcholine Stimulation and The Contractions Of Guinea Pig Tracheal Smooth Muscle Induced By 10−4M Histamine Stimulation. Furthermore, The Extract Inhibited The Contractions Of Rabbit and Guinea Pig Aortae Induced By 10−4M Norepinephrine Stimulation. These Inhibitions Were Concentration-Dependent and Reversible. These Data Suggest That This Seed Extract Has Antispasmodic, Anticholinergic, Antihistaminic and Antiadrenergic Effects.

SUMMARY: Data of 17 male patients with a final diagnosis of transient osteoporosis (TO) of the hip seen at the radiology department of a university hospital over a period of 7 years were retrospectively studied. Comparison of the proportion of doctors among TO cases with that among other hip joint pathologies revealed a significant difference. PURPOSE: The objective of this study is to present clinical and radiological findings of hip TO and to assess the association of the condition with patients' occupation. MATERIALS AND METHODS: Data of 17 male patients with a final diagnosis of transient osteoporosis of the hip seen at the radiology department of a university hospital over a period of 7 years were retrospectively studied. RESULTS: The diagnosis of transient hip osteoporosis was in accordance with the published literature for clinical, imaging findings, and laboratory results. Among the 17 cases of male transient hip osteoporosis, 65% were physicians and 12% were commercial pilots. Comparison of the proportion of doctors among TO cases with that among other hip joint pathologies revealed a significant difference. Abnormal low hormone levels of testosterone and 25-cholicalciferol (vitamin D) were detected in three and two patients, respectively. CONCLUSION: The preponderance of physicians among patients with transient hip osteoporosis has not been previously reported. Etiological contribution of endocrine pathology and type of occupation to the causation of transient osteoporosis merits further research.
