Gass described the acute posterior multifocal placoid pigment epitheliopathy in 1968. The disturbance of visual function is generally temporary with subsequent recovery. We describe one case of peripapillary and macular neovascularization with decreasing visual acuity due to macular haemorrhage followed by a fibro-glial scar. The pathogeny of the syndrome can explain the possible neovascularization. Neovascularization has been more often described with serpiginous choroiditis.

Background: Radiation-induced sarcoma (RIS) is an exceptionally rare occurrence following radiation therapy, and manifestation usually occurs after a several-year latency period. Herein, the authors report the development of a radiation-induced osteosarcoma of the frontoparietal calvaria following treatment for an oligodendroglioma in an 84-year-old woman.
Observations: The patient had been diagnosed with a grade III anaplastic oligodendroglioma when she was 78 years old.
Brucellosis, caused by a facultative intracellular gram-negative coccobacillus, is one of the most common zoonotic infections worldwide. Very rarely, brucellosis can cause periprosthetic joint infections (PJI). In this case-based literature review, we summarize the current medical literature regarding Brucella PJI, with the aim to raise awareness among clinicians, particularly in non-endemic areas.

Atypical mycobacteria can cause rare and atypical infections of the hand. We report the case of an immunocompetent 46-year-old male initially presenting with thumb felon and progressively developing symptoms of carpal tunnel syndrome, tenosynovitis of multiple fingers and a sporotrichoid lymphocutaneous infection causing chronic cutaneous lesions all over the body. We would like to highlight the diagnostic and therapeutic difficulties of these atypical infections, which mimic other conditions and can cause a lot of morbidity.

Chryseobacterium indologenes is a rare human pathogen which is nowadays considered an emerging fearsome organism because of its upcoming antibiotic resistance. We present a quite unique case of a multi drug resistant C. indologenes surgical wound infection in a patient submitted to cannulated screw fixation of a displaced medial malleolus fracture.

Optimal embryonic development depends upon cell-signaling molecules released by the maternal reproductive tract called embryokines. Identity of specific embryokines that enhance competence of the embryo for sustained survival is largely lacking. The current objective was to evaluate effects of three putative embryokines in cattle on embryonic development to the blastocyst stage.
