Cranial osteolytic metastases as the only recurrence of gastric carcinoma.

The purpose of this case report is to increase the knowledge about bone metastatic pattern in gastric cancer. A 59-year-old man presented with headache three years after a total gastrectomy for signet-ring cell carcinoma. Head computed tomography and magnetic resonance imaging showed multiple osteolytic lesions of the cranial vault and base, consistent with metastatic or haematological disease. Bone scintigraphy confirmed areas of accumulation only in the skull. An extensive search didn't show any other tumor. Bone biopsy revealed metastatic signet-ring cell carcinoma. In gastric cancer, bone metastases are generally associated with metastases in lymph nodes, liver, and lung, and have a higher frequency in the thoracolumbar spine. However, cranial bone metastases presenting with headache may be the only manifestation of gastric cancer recurrence.

Bosentan treatment for Raynauds phenomenon and skin fibrosis in patients with Systemic Sclerosis and pulmonary arterial hypertension: an open-label, observational, retrospective study.

Raynaud?s phenomenon (RP) and cutaneous fibrosis are the distinctive manifestations of scleroderma, in which Endothelin-1 plays a fundamental pathogenetic role. Bosentan, an Endothelin-1 receptor antagonist used for the treatment of pulmonary arterial hypertension, retards the beginning of new sclerodermic digital ulcers (DU). This open-label, observational, retrospective study verified the effect of Bosentan on RP and skin fibrosis in sclerodermic outpatients affected by pulmonary arterial hypertension without DU. Fourteen subjects (13 women, 1 man; mean age 60 ± 7.5 years; ten with limited and four with diffuse scleroderma) were observed at baseline (T0) and after four (T1), twelve (T2), twenty-four (T3) and forty-eight (T4) weeks during treatment with Bosentan. They were evaluated for daily quantity and duration of RP attacks and skin thickness (using modified Rodnan total skin score, MRSS). Videocapillaroscopic evaluation was performed at T0 and T4. Bosentan decreased significantly the number and duration of RP attacks, beginning at T2 (p<0.05). Videocapillaroscopy showed significant improvement of microcirculatory patterns at T4 (p<0.05). MRSS decreased throughout the study, reaching the statistical significance at T3 and T4 (p<0.01) in the whole cohort. The present data suggest that Bosentan is effective in stabilizing the microcirculation involvement and in improving skin fibrosis irrespective of scleroderma patterns.
