Hypogonadotropic hypogonadism as a cause of NOA and its treatment.

Asian J Androl

October 2024

Section of Andrology, Department of Urology, Istanbul School of Medicine, Istanbul 34093, Türkiye.

Hypogonadotropic hypogonadism (HH) represents a relatively rare cause of nonobstructive azoospermia (NOA), but its knowledge is crucial for the clinical andrologists, as it represents a condition that can be corrected with medical therapy in 3 quarters of cases. There are forms of congenital HH, whether or not associated with an absent sense of smell (anosmic HH or Kallmann syndrome, and normosmic HH, respectively), and forms of acquired HH. In congenital HH, complete absence of pubertal development is characteristic.

Functional Ankle Reconstruction Technique After Total Calcanectomy.

J Am Podiatr Med Assoc

July 2024

†Department of Orthopaedics and Traumatology, Istanbul University, Istanbul School of Medicine, Istanbul, Turkey.

Background: Although comminuted fractures, osteomyelitis, large skin ulcers, and malignant tumors are rarely seen in the calcaneus, it is a problematic region to treat because it is not an actual compartment and has insufficient blood supply. Few foot and ankle surgeons would recommend total calcanectomy in various cases of malignant tumors, comminuted fractures, ulcerations of the heel often seen in diabetic patients, and chronic osteomyelitis. After calcanectomy, if functional reconstruction is not performed, the patient will experience loss of function, pain, wound problems, talonavicular dislocations, and additional surgical interventions.

Objective: The aim of this study was to biomechanically compare a new lateral-pinning technique, in which pins engage the medial and lateral columns of the distal humerus in a divergent configuration in both the axial and sagittal planes instead of the coronal plane, with the cross-pin, and with 2 and 3 coronally divergent lateral-pin techniques in a synthetic humerus model of supracondylar humerus fractures.

Methods: Thirty-six identical synthetic models of the humerus simulating a standardized supracondylar humerus fracture were included in this study. They were divided into 4 groups based on the pin configuration of fixation: the new 3-lateral pin-fixation technique (group A), 2 crossed pins (group B), 3 divergent lateral pins (group C), and 2 divergent lateral pins (group D).
