Early left ventricular systolic and diastolic dysfunction in patients with newly diagnosed obstructive sleep apnoea and normal left ventricular ejection fraction.

UNLABELLED: The aim of the study was to evaluate whether obstructive sleep apnea (OSA) contributes directly to left ventricular (LV) diastolic and regional systolic dysfunction in newly diagnosed OSA with normal left ventricle ejection fraction. METHODS: 125 consecutive patients were prospectively enrolled in the study. Control group consisted of 78 asymptomatic age-matched healthy subjects who did not have any cardiovascular and respiratory diseases. All patients had undergone overnight polysomnography and standard transthoracic and tissue Doppler imaging echocardiogram. RESULTS: The E/A ratio and the peak E wave at mitral flow were significantly lower and the peak A wave at mitral flow was significantly higher in OSA patients compared with control subjects. Left ventricle isovolumetric relaxation time (IVRT) and mitral valve flow propagation (MVFP) were significantly longer in OSA patients than in controls. Tissue Doppler derived S' amplitude of lateral part at mitral valve (S'Lm) and E' wave amplitudes both at the lateral (E'Lm) and septal parts of the mitral valve (E'Sm) were significantly lower in OSA patients compared to controls. CONCLUSION: Newly diagnosed OSA patients with normal global LV function have significantly impaired diastolic function and regional longitudinal systolic function. OSA is independently associated with these changes in LV function.

Small bowel adenocarcinoma mimicking a large adrenal tumor.

INTRODUCTION: Adenocarcinoma of the small bowel is a rare gastrointestinal neoplasm usually affecting the distal duodenum and proximal jejunum. Because of their rarity and poorly defined abdominal symptoms, a correct diagnosis is often delayed. CASE OUTLINE: We present a 43-year-old woman admitted at the Clinic for Endocrinology due to a large tumor (over 7 cm) of the left adrenal gland.The tumor was detected by ultrasound and confirmed by CT scan.The patient complained of abdominal pain in the left upper quadrant, fatigue and septic fever. Normal urinary catecholamines excluded pheochromocytoma. The endocrine evaluations revealed laboratory signs of subclinical hypercorticism: midnight cortisol 235 nmol/L, post 1 mg - overnight Dexamethasone suppression test for cortisol 95.5 nmol/L and basal ACTH 4.2 pg/mL. Plasma rennin activity and aldosterone were within the normal range. Surgery was performed. Intraoperative findings showed signs of acute peritonitis and a small ulceration of the jejunum below at 70 cm on the anal side from the Treitz's ligament. Adrenal glands were not enlarged. Patohistology and immunochemistry identified adenocarcinoma of the jejunum without infiltration of the lymphatic nodules. The extensive jejunal resection and lavage of the peritoneum were performed. Due to complications of massive peritonitis, the patient died seven days after surgery. CONCLUSION: Poorly defined symptoms and a low incidence make the diagnosis of small bowel carcinoma, particularly of the jejunal region, very difficult in spite of the new endoscopic techniques.
