A number of surgical procedures that significantly change the penile anatomy and vasculature can be used to manage pathologic conditions of the penis (eg, congenital and acquired deformities, erectile dysfunction, priapism). Phallic reconstruction surgery can be used for sex reassignment and after penile amputation or for correction of congenital malformations. Color Doppler ultrasonography (US) clearly depicts the normal penile anatomy and postoperative changes (eg, changes of the tunica albuginea, extraalbugineal pathologic fluid collections, cavernosal tissue changes produced by scars and fibrosis). It is also effective in evaluating surgery-related complications and determining the causes of erectile dysfunction and other unsatisfactory long-term results. Moreover, color Doppler US of the penile vessels and vascular anastomoses following revascularization allows direct evaluation of flow characteristics, shunt patency, and venous engorgement. Color Doppler US is the imaging modality of choice in evaluating patients who have undergone penile surgery.

Perioperative ultrasound screening of lower extremity veins is effective in the prevention of fatal pulmonary embolism in orthopedic patients.
Sci Rep
January 2025
Department of Orthopedics and Traumatology, Honghui Hospital, Xi'an Jiaotong University, Xi'an, 710054, China.
Patients at high risk of deep vein thrombosis are recommended to undergo lower-extremity ultrasonography to screen for pulmonary embolism (PE); however, there are few reports on whether this can effectively reduce the occurrence of fatal pulmonary embolism (FPE). This study aimed to assess the risk factors associated with PE and to investigate whether perioperative ultrasound screening of lower extremity veins in orthopedic patients can effectively reduce the incidence of FPE. We enrolled 137 patients with PE who underwent orthopedic surgery between 2013 and 2020.

Department of Cardiology, Uenonomori Animal Hospital, Tokyo, Japan.
Objectives: Surgical options for mitral valve repair in dogs are unstandardized and influenced by various factors. This study describes a four-point surgical technique (MI-4) to reduce mitral regurgitation and provides data from a study of dogs with 12 months of follow up.
Methods: Twenty-five dogs with stages C or D mitral insufficiency were treated by one of two surgeons using the MI-4 procedure at Ueno no Mori Animal Hospital between October 2021 and May 2023.
Utility of color Doppler imaging in patients with retinoblastoma treated by intra-arterial chemotherapy.
J AAPOS
December 2024
Medical College of Wisconsin, Milwaukee, Wisconsin. Electronic address:
Background: There are no clinical parameters that predict response to intra-arterial chemotherapy (IAC), which is a first-line treatment for primary and recurrent unilateral retinoblastoma. We evaluated the utility of ophthalmic ultrasound with color Doppler imaging to predict retinoblastoma response to IAC treatment.
Methods: The medical records of 14 retinoblastoma patients (20 eyes) treated with IAC were reviewed retrospectively.
Does tocilizumab eliminate inflammation in GCA? A cohort study on repeated temporal artery biopsies.
RMD Open
December 2024
Unit of Rheumatology, Azienda USL - IRCCS di Reggio Emilia, Reggio Emilia, Italy
Background: Vascular inflammation persists in temporal artery biopsy (TAB) of giant cell arteritis (GCA) patients even after prolonged glucocorticoid (GC) therapy. We aimed to evaluate the histological impact of adding tocilizumab (TCZ) to GCs.
Methods: We enrolled all consecutive GCA patients with an inflammed TAB at diagnosis who were treated with TCZ and GCs for ≥6 months and followed from December 2017 to December 2023.
Fluctuations of antimüllerian hormone, ovarian follicular reserve, and antioxidant status throughout the estrous cycle in aged mares.
Open Vet J

Theriogenology Department, Faculty of Veterinary Medicine, Cairo University, Giza, Egypt.
Background: Senility influences fertility in women and companion animals, especially horses.
Aim: This study aimed to investigate the effect of aging in horses on the daily changes in the dominant follicle (DF) dynamics and hemodynamics, antimüllerian hormone (AMH), enzymes, antioxidants, and ovarian hormones during the estrous cycle.
Methods: Ovaries of old mares ( = 5, age >20 years) and young native mares ( = 6, age <10 years) were scanned during 6 different estrous cycles from March 2022 to August 2023 with Doppler ultrasound.
