Persistent Chloracne in a Tank Mechanic

Chloracne, a misnomer and its implications.

For the trained clinician, ‘chloracne’ is one of the differential diagnoses when an acneiform rash develops in a previously non-acneic patient. Yet there has been so far no clinical sign specific for ‘chloracne’ that would not be present in some patients with either ‘spontaneous’ or exogenous acne. Most of the descriptions in the literature either on sporadic or epidemic cases do not provide us...

Pleural mesothelioma in a lift mechanic.

Pleural mesothelioma in a brake mechanic.

A high risk for the development of diffuse pleural mesothelioma is known to exist in various occupational settings associated with the use of asbestos.' Although a serious hazard has been recognised among asbestos miners, millers, and shipyard workers, recent evidence suggests that a high risk of mesothelioma may exist among occupational groups previously thought to be at low risk for developin...

Congenital persistent urachus, urethral obstruction and uroperitoneum in a calf

Persistent patent urachus with other accompanying anomalies like urethral obstruction and uroperitoniumquickly deteriorates animal conditions which necessitate prompt surgical intervention and animal salvage. A10-day-old calf was referred to clinic with mildly distended abdomen, history of umbilical dribbling and nosigns of normal urination since birth. On clinical laboratory results and ancill...

Mechanic Waves in Sand: Effect of Polydispersity

The sound propagation mechanisms inside dense granular matter are challenging the attempts to describe it because of the discrete nature of the material. Phenomena like dissipation, scattering, and dispersion are hard to predict based on the material state and/or properties and vice-versa. We propose here a simulation method using dynamic discrete elements in order to get more insight in this p...
