An analysis was made of the results of an all-round clinical, ultrasound, phlebotonometric and phlebographic examination of 89 patients with the clinical evidence of chronic venous insufficiency (CVI) of the pelvis. It is established that small pelvis varicosis develops because of hemodynamic disorders in the system of the inferior vena cava, iliac and left renal veins. In men, blood reflux from the iliac vein to the parietal tributaries leads to the development of the atypical forms of varicosis. In women, the left- sided regional renal venous hypertension induces valvular insufficiency of the left ovarian vein with the extent of the renoovarian blood reflux to the pampiniform, uterovaginal, presacral, vesical and rectal venous plexus. The concomitant action of the caval and renoovarian blood refluxes causes the origination of the syndrome of the blood overfilling of the pelvic organs and varicosis of the pubis, perineum, vulva, and buttocks. The clinical, ultrasound and phlebographic appearance of small pelvis varicosis is described in detail.

Ureteropelvic junction obstruction (UPJO) is a common pediatric condition often treated with pyeloplasty. Despite the surgical intervention, postoperative urinary tract infections (UTIs) occur in over 30% of cases within six months, adversely affecting recovery and increasing both clinical and economic burdens. Current prediction methods for postoperative UTIs rely on empirical judgment and limited clinical parameters, underscoring the need for a robust, multifactorial predictive model.

Gibbons, a type of lesser ape, are brachiators but also walk bipedally and without forelimb assistance, not only on the ground but also on tree branches. The arboreal bipedal walking strategy of the gibbons has been studied in previous studies in relation to two-dimensional (2D) kinematic analysis. However, because tree branches and the ground differ greatly in width, leading to a constrained foot contact point on the tree branches, gibbons must adjust their 3D joint motions of trunk and hindlimb on the tree branches.

We present a case of a young woman who presented with blurring of vision in her right eye, worsening on near work. Detailed ophthalmic and neurological evaluation was done, which revealed light near dissociation, vermiform iris movements, constriction to diluted pilocarpine with absent deep tendon reflexes. Laboratory investigation indicated mild iron deficiency anemia and reduced vitamin D3 level.

The differential diagnoses for patients presenting with right iliac fossa pain are broad, with appendicitis almost always on the top of the list. Although rare, diverticulosis of the appendix, complicated by inflammation, should be considered in these patients. We report a case of a middle-aged female with right iliac fossa pain with a high inflammatory marker.
