Acute Lung Toxicity After Intralesional Bleomycin Sclerotherapy.

Bleomycin has progressively been used to treat low-flow vascular malformations in children. No significant systemic side effects have been reported in large series after low doses, but some authors are still concerned about its use. We report a case of a severe acute lung toxicity after a low dose of a second bleomycin intralesional injection in a 5-year-old girl. She had no risk factors and presented a cervical low-flow venous malformation. Twenty-four hours after this second administration, she presented with fever and respiratory distress. A chest radiograph showed bilateral opacities and computerized tomography revealed extensive and diffuse lung ground-glass opacities. The patient started to receive intravenous methylprednisolone, but she experienced progressively increased dyspnea, and montelukast was added. She improved and was discharged from the hospital without oxygen support, with montelukast and prednisolone for tapering doses during months. Five months after onset, the patient is developing well, is active, and walks and talks without dyspnea. A new low-dose computed tomography shows improvement in radiologic findings. This is the second case of pulmonary toxicity observed in a child after bleomycin intralesional administration, and the first reported after the lowest dose of this drug to date (7 mg: 0.28 mg/kg; 10 U: 0.4 U/kg). A delay in the diagnosis and treatment of this complication can be fatal. Any physician who treats these patients must be alert and consider this complication in children with respiratory symptoms after bleomycin sclerotherapy. Early detection of pulmonary toxicity would allow prompt therapy and could avoid pulmonary damage.

Use of carotid compression in a patient with arteriovenous malformation.

We report a case of a patient with a high flow arteriovenous malformation (AVM)i n the orbit, who developed a severe compartment syndrome, and was successfully treated with manual carotid compressions. The patient suffered a progressive proptosis, restriction of ocular motility and decreased of the visual acuity of the right eye. Embolization had a high risk of serious complications due to fistula location, so an alternative treatment consisting in carotid compressions was prescribed. Manual carotid compression is a non-invasive alternative technique to treat AVMs in patients with high risk of embolization episodes.

Fractura vertebral aguda y técnicas de refuerzo vertebral / Acute vertebral fracture and vertebral reinforcement techniques

La alta incidencia de las fracturas por fragilidad y especialmente de las fracturas vertebrales (FV) en mujeres con osteoporosis posmenopáusica obliga a abordar este tema una y otra vez. En este manuscrito se actualizan los datos epidemiológicos que indican la magnitud del problema y se revisan alternativas de tratamiento farmacológico, tanto para disminuir el dolor producido por la FV como para prevenir la presentación de nuevas fracturas osteoporóticas de cualquier tipo, indicando los agentes antirresortivos y osteoformadores disponibles actualmente. En los casos de FV por compresión, en las que el tratamiento farmacológico habitual no produce mejoría del dolor y siempre que no existan contraindicaciones, puede ser muy apropiado realizar vertebroplastia o cifoplastia (AU)

The high incidence of fractures by fragility and, especially of the vertebral fractures in osteoporotic postmenopausal women, forces us to approach this subject once more. In this manuscript epidemiological data that indicates the magnitude of the problem will be updated. Treatment alternatives to decrease back pain produced by vertebral fracture are will be reviewed, and the prevention of the occurrence of new osteoporotic fractures of any type, through the administration of suitable antiresorptive and bone-forming pharmacological agents to increase bone mineral density will also be addressed. In some patients with painful vertebral compression fractures it is possible obtain an analgesic effect by percutaneous vertebroplasty or by kiphoplasty using polymethylmetacrilate cement or calcium- phosphate cement, injected into vertebral bodies (AU)
