Black Urine and Black Pleural Fluid: A Distinctive Presentation of Metastatic Melanoma

Metastatic melanoma is an uncommon clinical entity which can have an unusual presentation. We describe a patient with metastatic melanoma who presented with diffuse melanosis cutis, black urine and black pleural effusion. Very few medical conditions can cause black discoloration of body fluids, so this should prompt physicians to search for a number of potential underlying causes.

Pneumothorax in the Emergency Room: personal caseload

The aim of this study was to collect information on the incidence, pathophysiology, treatment and mortality of pneumothorax in the Emergency Room. Pneumothorax is classified as spontaneous (primary, secondary or catamenial) or traumatic (iatrogenic or secondary to a blunt or penetrating chest injury). Between January 2007 and December 2009, 102 patients with pneumothorax were seen in our Emergency Room. Their records were examined and their data collected retrospectively. The type and side of the pneumothorax and age, sex, incidence and mortality were analyzed. The cases, involving 93 males and 9 females, broke down as follows: 68 spontaneous (66.7%), 33 traumatic (32.3%) and one iatrogenic (0.98%). The mean age was 47.3 (range 12-99); the incidence was 0.10%. There were no deaths due to pneumothorax in the Emergency Room. Traumatic pneumothorax was associated with blunt chest trauma, pleural effusion, hemothorax, cranial trauma, fractured collarbone, upper and lower limb fracture, pelvic fracture, vertebral and spinal trauma, sternum fracture and abdominal trauma. Pneumothorax is a common clinical problem. A multidisciplinary approach is essential to reduce the risk of morbidity and mortality. The incidence of pneumothorax in the Emergency Room was similar to that reported in the literature, while mortality data cannot be compared due to the lack of published studies.

TAFRO Syndrome in a Patient of South-American Descent

A 31-year-old Caucasian woman of South-American descent was diagnosed with a variant of multicentric Castleman disease (MCD) that has been reported in Japan as Castleman-Kojima disease. This is a systemic inflammatory disorder known as TAFRO Syndrome which includes thrombocytopenia, polyserositis (ascites/pleural effusion), microcytic anemia, myelofibrosis, fever, renal dysfunction and organomegaly, with immunologic disorder, polyclonal hypergammaglobulinemia, and elevated levels of interleukin-6 (IL-6) and the vascular endothelial growth factor present in serum and/or effusions. Optimal therapies are not well established. The patient was treated with methylprednisolone and rituximab. Following the start of treatment, the patient has been asymptomatic for over 8 months.

Paradoxical Deterioration During Anti-Tuberculous Therapy in Non-HIV-Infected Patients with Pleural Tuberculosis: A Pragmatic Approach

We report a case of paradoxical deterioration. A male patient diagnosed with pleural tuberculosis, but who was not infected with human immunodeficiency virus (HIV), experienced clinical deterioration 3 weeks after the initiation of anti-tuberculous treatment. After other diagnoses were ruled out, a paradoxical response to treatment was established and the patient was started on systemic corticosteroids. Paradoxical response to treatment should be considered in patients with clinical deterioration after they start on anti-tuberculous treatment.
