Penile dermatology for the general practitioner: A pragmatic approach to diagnosis and management.

Background: Genital skin conditions are rare and pose a diagnostic challenge due to their diverse pathology. Patient anxiety and referral decisions add complexity for primary caregivers. Demographics and overlapping symptoms complicate diagnosis, causing anxiety for both patients and clinicians.

Case Studies Discussing the Pathology, Immunogenicity, and Proposed Mechanism of Toxicity of an Inhaled Anti-TGFβ Humanized Fab Antibody in Non-Human Primates and Mice.

Treatment of nonhuman primates and mice with a humanized antigen-binding fragment (Fab) antibody (UCBFab) inhibiting transforming growth factor β via daily inhalation for up to 13 weeks resulted in low systemic exposure but high local exposure in the lung. Target engagement was demonstrated by reduced levels of signal transducers, phosphoSMAD and plasminogen activator inhibitor-1 in the bronchoalveolar lavage fluid (BALF). Treatment was associated with a high frequency and titer of antidrug antibodies, indicating high local immunogenicity, and local pathology within the lung and draining lymph nodes.

Skin disease of penis and male genitalia is linked to atopy and circumcision: caseload in a male genital dermatology clinic.

Background/objectives: Male genital dermatoses are a common and underappreciated cause of morbidity. Its prevalence and the characteristics of patients presenting with these conditions are poorly understood. The aim of the study was to ascertain which dermatoses were referred to the Male Genital Dermatology Clinic in Melbourne, Australia and to determine whether circumcision and atopy are associated with male genital skin disease.

PDGFR Inhibition Results in Pericyte Depletion and Hemorrhage into the Corpus Luteum of the Rat Ovary.

The growth plate, ovary, adrenal gland, and rodent incisor tooth are sentinel organs for antiangiogenic effects since they respond reliably, quantitatively, and sensitively to inhibition of the vascular endothelial growth factor receptor (VEGFR). Here we report that treatment of rats with platelet-derived growth factor receptor beta (PDGFRβ) inhibitors that target pericytes results in severe ovarian hemorrhage with degeneration and eventual rupture of the corpus luteum. Evaluation of the growth plate, adrenal gland, and incisor tooth that are typical target organs for antiangiogenic treatment in the rodent revealed no abnormalities.

Review of the effects of anti-angiogenic compounds on the epiphyseal growth plate.

The formation of new blood vessels from a pre-existing vascular bed, termed "angiogenesis," is of critical importance for the growth and development of the animal since it is required for the growth of the skeleton during endochondral ossification, development and cycling of the corpus luteum and uterus, and for the repair of tissues during wound healing. "Vasculogenesis," the de novo formation of blood vessels is also important for the proper function and development of the vascular system in the embryo. New blood vessel formation is a prominent feature and permissive factor in the relentless progression of many human diseases, one of the most important examples of which is neoplasia.
