Role of mammalian target of rapamycin inhibitor in the treatment of metastatic epithelioid angiomyolipoma: A case report

Epithelioid angiomyolipoma has malignant potential; however, no effective therapy has been established for advanced cases. A 50‐year‐old woman with a history of right nephrectomy for epithelioid angiomyolipoma was referred to our institution. Computed tomography and magnetic resonance imaging showed multiple tumors in her lung, liver and pelvic cavity. The liver and pelvic tumor specimens obtained by needle biopsy confirmed the diagnosis of epithelioid angiomyolipoma recurrence. The patient was treated with everolimus (10 mg/day). Three months later, pulmonary lesions disappeared; liver and pelvic tumors significantly shrank in size, but the pelvic tumor gradually enlarged again. We carried out surgical resection of the residual liver and pelvic cavity tumors. Although the mammalian target of rapamycin inhibitor seems to be effective for treating epithelioid angiomyolipoma, its long‐term effects remain unknown. Thus, aggressive administration of a multidisciplinary treatment including molecular target therapy and surgical resection is required to improve the prognosis of epithelioid angiomyolipoma.     

Cutaneous mastocytosis associated with a mixed germ cell tumour of the ovary: report of a case and review of the literature

A 10-year-old girl with a mixed germ cell tumour of the ovary, treated by surgery and chemotherapy, developed cutaneous mastocytosis approximately 8 months after starting chemotherapy. This is the sixth report of a germ cell tumour associated with mastocytosis. c-kit receptor point mutations, including Asp816Val and Val560Gly were absent in a biopsy specimen obtained from lesional skin.     

Asymptomatic hyperglycaemia is associated with increased intimal plus medial thickness of the carotid artery

Summary Atherosclerotic changes have not been demonstrated directly in asymptomatic hyperglycaemic non-diabetic subjects, although high mortality due to coronary heart disease has been reported. We measured arterial wall thickness non-invasively, in order to directly demonstrate atherosclerosis of the carotid arteries of hyperglycaemic non-diabetic subjects and to evaluate its risk factors.The thicknesses of the intimal plus medial complex (IMT) of the carotid arteries of 112 asymptomatic hyperglycaemic non-diabetic subjects (aged 22–81, 95 males and 17 females) were compared with those of 55 healthy male subjects and 211 non-insulin-dependent NIDDM male diabetic patients. The subjects were subgrouped into impaired glucose-tolerant (IGT) subjects who had a 2-h glycaemic level of more than 7.8 mmol/l, and non-IGT subjects whose 2-h glycaemic levels were within 6.7–7.7 mmol/l.Non-IGT and IGT subjects showed significantly greater IMTs than age-matched healthy males and showed no significant differences compared to age-matched NIDDM patients. Multivariate analysis demonstrated that the risk factors for IMT of non-IGT and IGT subjects were age and systolic blood pressure. According to data on the accumulation of atherogenic risks (hypertension, dyslipidaemia, and smoking), IMT increased linearly in non-IGT and IGT subjects. However, non-IGT and IGT subjects without hyperlipidaemia, hypertension, or smoking risk still had significantly greater IMT than age-matched normal males (1.019±0.063 vs 0.770±0.111 mm, p<0.05). Prevalence of ECG-indicated coronary heart disease was significantly higher in hyperglycaemic non-diabetic subjects and NIDDM with increased carotid arterial wall thickness (IMT 1.1 mm) than in those without increased thickness (IMT<1.1 mm). Asymptomatic hyperglycaemic non-diabetic subjects have increased thickness of their carotid arteries compared to age-matched male NIDDM patients. As one of several independent risk factors, mild hyperglycaemia advances atherosclerosis, which leads to coronary heart disease.Abbreviations IMT Intimal plus medial complex - NIDDM non-insulin-dependent diabetes mellitus - IGT impaired glucose tolerance - CHD coronary heart disease - T-Chol serum total cholesterol - HDL-C high-density lipoprotein cholesterol - TG serum triglycerides     

Protruding atherosclerotic aortic plaques and dyslipidaemia: correlation to subtypes of ischaemic stroke.

AIMS: To evaluate whether thoracic aortic plaques together with dyslipidaemia are related to ischaemic stroke, and if so, to which of the subtypes of stroke. METHODS AND RESULTS: We performed transoesophageal echocardiography in 50 patients with acute ischaemic stroke and in 401 controls. The aorta was divided into two segments: (1) the proximal, proximal to the left subclavian artery, and (2) the distal aorta. Protruding plaques (Intima > or =4 mm in thickness) in the proximal aorta were detected in 14 of the 50 patients (28%) with stroke, and in 53 of the 401 controls (13%) (P<0.01). Plaque score in the proximal aorta (2.1 +/- 1.8 vs 0.9 +/- 0.7; P<0.05), low-density lipoprotein cholesterol level (3.60 +/- 0.85 vs 2.87 +/- 0.72 mmol/l; P<0.05), and apolipoprotein B/A-I ratio (0.98 +/-0.17 vs 0.73 +/- 0.16; P<0.005) were higher in patients with athero-thrombotic than in cardioembolic stroke. The score in the proximal aorta correlated with low-density lipoprotein cholesterol level (r=0.44, P<0.005) and apolipoprotein B/A-I ratio (r=0.40, P<0.01). CONCLUSION: Severe plaques in the proximal aorta together with dyslipidaemia are seen more frequently in patients with atherothrombotic stroke. Lipid analysis may contribute to the prediction and the treatment of the patients who are at high risk for atherothrombotic stroke.     

Thallium scintigraphy for the prognosis of idiopathic dilated cardiomyopathy

OBJECTIVES: This study evaluated the significance of perfusion defects demonstrated by thallium-201 and age in the prognosis of patients with idiopathic dilated cardiomyopathy. METHODS: Seventy-four dilated cardiomyopathy patients underwent thallium scintigraphy as well as clinical and hemodynamic examination. RESULTS: Abnormal perfusion defects were present in 23 of 38 patients aged < 60 years (61%) and in 26 of 36 elderly patients aged > or = 60 years (72%; NS). Univariate analysis showed that such perfusion defects were a significant predictor of cardiac death only in patients aged < 60 years (p = 0.015). Stepwise discriminant analysis also revealed that perfusion defects were a significant predictor in patients aged < 60 years (Wilks' lambda 0.499, chi-square test 20.2, p = 0.003). Perfusion defects were not more important than the history of syncope or stroke in elderly dilated cardiomyopathy patients. Twenty-one patients died of disease-related causes during 58 +/- 43 months. The five-year survival rate was better in patients aged < 60 years without than in those with perfusion defects (100% vs 58.4%, respectively), but not affected in patients aged > or = 60 years (66.7% vs 62.2%). CONCLUSIONS: Thallium scintigraphy is valuable for the prognosis of patients with dilated cardiomyopathy aged < 60 years who are usually candidates for heart transplantation. Absence of thallium perfusion defects may indicate good long-term prognosis.
