Invasive rhinosinusitis due to in an adolescent man with new-onset leukaemia: a diagnostic dilemma.

An adolescent boy with newly diagnosed T-cell acute lymphoblastic leukaemia developed right eye and facial pain, and a 1 cm × 2 cm area of black eschar over his hard palate. Initial differential diagnosis included rhinocerebral mucormycosis and aspergillosis, and he was started on liposomal amphotericin B. Later, he underwent nine surgical debridements of his sinus cavities, resection of a third of his palate and right orbital exenteration.

Terrestrial Locomotion in American Eels (Anguilla rostrata): How Substrate and Incline Affect Movement Patterns.

Fishes overcome a variety of challenges in order to invade the terrestrial environment. Terrestrial invasions by fish occur over a variety of environmental contexts. In order to advance their bodies on land, fishes capable of terrestrial excursions tend to use one of three different types of locomotor modes: axial-based, appendage-based, or axial-appendage-based.

Diagnosis of stenosis within the popliteal-femoral venous segment upon clinical presentation with a venous ulcer and subsequent successful treatment with venoplasty.

This case study reports the diagnosis and treatment of a lower limb venous ulcer with abnormal underlying venous pathology. One male patient presented with bilateral varicose veins and a right lower limb ulcer. Upon investigation, full-leg duplex ultrasonography revealed total incompetence of the great saphenous vein in the left leg.

Implication of foam sclerosant inactivation by human whole blood in a laboratory setting.

Background During sclerotherapy, it has been recommended to confirm intravenous placement of the needle by aspirating blood into the sclerosant syringe. This may inactivate some, or all of the sclerosant. Aims To quantify the volume of human blood needed to completely inactivate 1 ml of sodium tetradecyl sulphate, and comparing fresh blood and blood that has been stored in an ethylenediaminetetraacetic acid tube.
