Scleredema diabeticorum in a patient: un uncommon etiology of restrictive lung pattern Escleredema diabeticorum en un paciente: una etiología infrecuente de patrón restrictivo pulmonar.

Scleredema adultorum of Buschke is a rare skin disease characterized by skin thickening and tightening typically at the neck and the upper part of the body. This thickening results from increased mucin deposition in the reticular dermis. Three variants are recognized.

Pneumonitis due to cytomegalovirus during chronic methotrexate treatment.

Although hypersensitivity pneumonitis is the most common pulmonary complication described during treatment with methotrexate, other complications like lymphoproliferative and infectious disease may be considered in the study of respiratory disease associated to methotrexate. The existence of an increased risk to developing infectious diseases may be similar to that observed during treatment with antagonists of tumor necrosis factor and corticosteroids, where Cytomegalovirus pneumonia is a serious complication; early diagnosis and treatment will prevent a potentially fatal outcome.

Reduction in size of renal angiomyolipoma after treatment with everolimus in lung transplantation due to lymphangioleiomyomatosis.

Lymphangioleiomyomatosis (LAM) is a rare disease characterized by abnormal proliferation of immature smooth muscle cells and cystic lung destruction, which determines the prognosis of the disease. The kidney angiomyolipomas are usually very common in this disease and are usually asymptomatic unless complications arise. In the absence of a curative treatment, recent publications show promising results in molecular therapy to prevent functional decline and to control the size of the angiomyolipomas.

Association of cellular adhesion molecules and oxidative stress with endothelial function in obstructive sleep apnea.

Objective: To evaluate the impact of oxidative stress and cellular adhesion molecules on ischemic reactive hyperemia (IRH) in patients with OSA.

Materials And Methods: Consecutive patients treated at a sleep laboratory and whose polysomnography showed an apnea hypopnea index (AHI) ≥5 were included in the study. Patients with acute illness receiving vasoactive medications were excluded.
