Abstract

30-50% of patients presenting with symptoms of congestive heart failure exhibit a near normal left ventricular systolic function at rest, and an impaired diastolic function of the heart may be causative. Despite a better prognosis than in systolic heart failure, frequency of hospitalizations due to diastolic heart failure is comparable with systolic heart failure. According to the criteria of Vasan and Levy diagnosis of diastolic heart failure is probable, if symptoms and signs of heart failure are accompanied in proximity (within 72 h) by objective evidence of normal left ventricular systolic function. Newer echocardiographic techniques (e. g., tissue Doppler) aid to confirm the diagnosis and to determine the severity of dysfunction and may substitute invasive demonstration of impaired left ventricular relaxation, filling, compliance or stiffness for standardized diagnosis. Incorporation of biochemical test (BNP [brain natriuretic peptide]) allows differential diagnosis and may increase the accuracy of diagnosis. Due to inconsistent diagnostic criteria, data from prospective randomized controlled trials for the treatment of diastolic heart failure are rare. Basic principles include treatment of the underlying disease, i. e., control of hypertension, diabetes, or obstructive airway disease. Angiotensin 1 antagonists (ARB) have proven effective in regression of left ventricular hypertrophy (LIFE) and may reduce morbidity, but not mortality (CHARM). Maintenance of sinus rhythm, heart rate control (beta-blockers, calcium channel blockers) and anti-ischemic therapy may be indicated in view of pathophysiological aspects. Diuretics should be administered with caution in patients with symptoms of congestion, digitalis is not useful in the treatment of isolated diastolic heart failure. The results of ongoing trials (e. g., I-Preserve) may offer new therapeutic options, and evidence-based guidelines for the so far often unsatisfactory treatment of diastolic dysfunction/heart failure are awaited.

Two-dimensional and three-dimensional transthoracic echocardiography in surgical planning for right atrial metastatic melanoma.

Melanoma is the most common form of cardiac metastases. Surgical excision has been shown to be an effective palliative measure. This requires detailed definition of cardiac anatomy in relation to the tumour. Two-dimensional (2D), three-dimensional (3D) transthoracic (TTE) and transoesophageal echocardiography (TEE), spiral computerised tomography (CT) and magnetic resonance imaging (MRI) have all been described in aiding surgical planning for excision of cardiac tumours. In this case report, 3D-TTE provided excellent anatomical definition for surgical planning of a large right atrial melanoma precluding the need for more invasive and expensive investigations.

The role of 2-deoxy-2-[F-18]fluoro-D-glucose positron emission tomography in disseminated carcinoma of unknown primary site.

BACKGROUND: The authors conducted a comprehensive review of the efficacy of 2-deoxy-2-[F-18]fluoro-D-glucose positron emission tomography (FDG-PET) in the detection of primary tumors in patients with disseminated carcinoma of unknown primary site. METHODS: Ten studies (involving a total of 221 patients) tat were published between 1998 and 2006 were reviewed. Each study evaluated the role of FDG-PET in the detection of unknown primary tumors after a conventional diagnostic workup. Although 94% of patients had a single site of metastases, the studies otherwise were very heterogeneous in the studied population, study design, and additional diagnostic workup. RESULTS: In 41% of patients, FDG-PET detected primary tumors that were not apparent after conventional workup. In this group of patients, the overall sensitivity, specificity, and accuracy rates of FDG-PET in detecting unknown primary tumors were 91.9%, 81.9%, and 80.5%, respectively. FDG-PET imaging also led to the detection of previously unrecognized metastases in 37% of patients. Lung cancers represented 59% of the detected tumors. FDG-PET had a notably high false-positive rate (58.3%) in tumors of the lower digestive tract. FDG-PET altered the clinical management in 34.7% of patients. Most of those patients (53%) received specific chemotherapy for lung and pancreatic cancers; whereas 12% received specific therapy for breast, ovarian, and prostate cancers; and 14% underwent surgery with curative intent. CONCLUSIONS: FDG-PET was an efficient method for detecting primary tumors that were undetected by other modalities and was sensitive for the detection of previously unrecognized metastases. FDG-PET significantly changed clinical management in approximately one-third of the patients studied.

Sulcus vocalis: a review.

Sulcus vocalis is described as a groove at the free edge of the vocal fold. Different types have been described: sulcus type I is superficial and may be considered as moreless physiologic. Sulcus type IIa corresponds to a kind of vergeture along the margin of the vocal fold. Its deepness is variable but sulcus vergeture may involve deeper layers of the lamina propria. Sulcus type IIb or pounch may be considered as an open cyst. Sulcus lead to a complex glottic dysfunction with, in the same time, a glottal leakage responsible for the breathy component of the dysphonia and a stiffness of the free edge responsible for the roughness. Diagnosis may be difficult even with the help of stroboscopy and finally is sometimes done only under general anesthesia. Etiology remains controversial and the authors present arguments for each theory, acquired or congenital. Treatment options include phonosurgery and speech therapy but phonosurgery gives results often disappointing and surgical treatment must be indicated prudently and patient must be intensively informed on what he or she can expect from the treatment that is mainly an increase of the loudness of the voice.
