This article describes a case of lung cancer with associated hypercalcitoninemia in a man with a goitre. The case raises the problem of the differential diagnosis between medullary thyroid carcinoma and a neuroendocrine neoplasm with ectopic calcitonin secretion. The article first reviews the physiology of calcitonin, then outlines the diagnostic tests that are required to investigate hypercalcitoninemia and finally discusses the interpretation of test results.

We now have access to a large library of publications validating transparietal thoracic echography in various clinical situations. Parietal lesions, including osteolysis, can be detected and biopsied during the thoracic ultrasound (TUS) examination. To evaluate the parietal extension of lung cancers, TUS has proved superior to tomodensitometry. Pleural effusions can be easily diagnosed and aspirated. Pneumothoraces can be detected using well defined lung artifacts with a high frequency probe. Pleural and peripheral lung nodules can be detected and biopsied with real time visualization; the procedure is safe and accurate. Lung consolidations with a pleural contact can be diagnosed; this is particularly useful for pregnant women. In conclusion, TUS is a precious diagnostic tool for chosen applications, and can help to guide interventional procedures. The portable devices are also very useful for bedridden patients or for out of hospital use. [less ▲]

Hypertension is a cardiovascular risk factor which needs a good evaluation before treatment. When this latter is decided, the target is to normalize high blood pressure. This requires a complete information of the patient; the latter will also receive individualized non pharmacological advices and, also, possibly different antihypertensive drugs. When blood pressure does not normalize, one must check the blood pressure measurement technique, the compliance to treatment and potential pharmacologic interferences. Secondary hypertension is only considered if resistance to therapy cannot be found. It should be remembered that obesity and sleep apnea disorders are responsible of many instances of refractory hypertension. [less ▲]

There exists several clinical types of scleroderma. Most of them show cutaneous manifestations. Skin involvement may be isolated (morphea) or be part of a multi-organ systemic disease. Objective non-invasive functional methods are useful in order to better assess the severity and evolution of the disease and the effects of treatments.

Some dermatologic disorders named "Invisible dermatoses" are defined by obvious clinical signs while histologic alterations remain discrete. This situation may lead to clinico-pathological discrepancies impeding the establishment of a diagnosis. In other cases, the skin looks clinically normal but the histological examination allows to disclose some systemic diseases. Systematic analysis of the skin biopsy complemented by histochemical and immunohistochemical techniques may help reach the diagnosis. [less ▲]

Under specific light illumination, skin produces peculiar fluorescent aspects. Such property can be used to provide diagnostic arguments or to disclose some peculiar functions of the skin. Some superficial infections (erythrasma, tinea versicolor, dermatophytic tinea,..) reveal fluorescence that may be intense. The pilosebaceous follicles enriched in Propionibacterium spp show fluorescence. Such property is lost during some anti-acne treatments. A quenching effect is observed after application of sunscreens. The (pre)neoplastic areas prepared for dynamic phototherapy become fluorescent. Pyranine labeling of the stratum corneum exhibits fluorescence allowing the assessment of the renewal activity of the epidermis. [less ▲]

Prevention of cardiovascular diseases should primarily focus on high-risk individuals. In the absence of atherosclerosis manifestations, such persons may be screened by the calculation of the absolute risk of complications during the next ten years or extrapolated at the age of 60 years. This calculation is based upon the analysis of most important risk factors of atherosclerosis. The mode of calculation that prevailed for many years used the Framingham equation determining the absolute coronary risk (both morbidity and mortality) in the next 10 years: a risk equal or superior to 20% is considered as high and requiring specific intervention. The Third Joint Task Force of European and other Societies on cardiovascular disease prevention in clinical practice recently proposed a new mode of calculation (SCORE) based upon the absolute risk of cardiovascular (and not exclusively coronary) mortality (only fatal events and not morbidity): according to SCORE, the threshold of high risk has been set at a risk equal or superior to 5% in the next 10 years. The present article compares the two modes of calculation with their own advantages and disadvantages. [less ▲]

The International Diabetes Federation recently proposed a so-called consensus definition of metabolic syndrome. According to this new definition, a subject has the metabolic syndrome if he/she has abdominal obesity (considered as a prerequisite and assessed, in the European population, by a waist circumference > 80 cm in women and > 94 cm in men) and, in addition, at least two other risk factors among 1) elevated fasting triglycerides > or = 150 mg/dl; 2) low HDL cholesterol HDL < 50 mg/dl in women and < 40 mg/dl in men; 3) increased arterial blood pressure > or = 130/ 85 mm Hg; and 4) elevated fasting plasma glucose concentration > or = 100 mg/dl. We will discuss the advantages and limitations of this new definition as well as the consequences of its use on the prevalence of the metabolic syndrome in the Belgian population. [less ▲]

Cardiac imaging has always been a challenge because of the continuous movement of the heart. Cardiac computed tomography (CT) has undergone an accelerated progression over the past decade, due to the combination of the high-speed rotation of the X-ray tube, the ECG-gating technique and the infra-millimeter spatial resolution. Multidetector CT allows visualisation of the coronary artery lumen and the detection of coronary stenosis after intravenous injection of contrast medium. Studies have demonstrated a high negative predictive value of CT coronary angiography (CTCA). CTCA may be reasonably used for the assessment of symptomatic patients, especially in the setting of equivocal treadmill or functional testing. Also, CTCA allows assessment of coronary bypass graft patency and recognition of aberrant coronary arteries. Limitations in the use of this technique exist: atrial fibrillation and other cardiac arrhythmias remain a contraindication; severe calcifications are the most frequent reason for impaired assessment of coronary arteries. High radiation doses prohibit the use of this test as a screening tool for asymptomatic patients. [less ▲]

As for other skeletal muscles, ventilatory muscle performance can be described in terms of strength and endurance. Ventilatory muscle strength is measured, for example, as the maximum inspiratory and expiratory mouth pressures. It is now a routine procedure in many pulmonary function laboratories. Measurements of ventilatory muscle endurance are more difficult but two general types of tests are used: maximum voluntary ventilation and inspiratory threshold loading. [less ▲]

Pressure ulcers represent a major health problem causing both considerable morbidity and a high financial burden for the healthcare system. The geriatric segment of the population at risk of pressure ulcer is progressively increasing. This condition occurs at home, in old people's homes and in hospitals as well.

Pleural involvements are common and various respiratory diseases including inflammatory, infectious, occupational, or neoplastic pathological entities...Pleural thickening and pleurisy are usual radiological presentation. Etiological diagnosis imposes a vast and sometimes difficult exploration and it, especially since the conventional imaging by radiology, ultrasound, scanning and nuclear magnetic resonance has no specific diagnostic criteria for pleural malignancy. The metabolic imaging by positron emission tomography (PET) has been gradually positioned in the decision-making algorithm exploration of the pleural disease due to its excellent sensitivity in the diagnosis of malignant pleurisy (88.8%-100%). The analysis of chemistry, bacteriology and cytology pleural fluid makes a significant contribution to the diagnostic approach. However, although inescapable, thoracocentesis has a diagnostic sensibility not exceeding 62%. Moreover, the sensibility of the pleural blind needle biopsies does not exceed 51%. So, thoracoscopy, more invasive, is often justified to precise pleural disease with a diagnostic sensitivity greater than 95%. Finally, despite the diagnostic arsenal available, over 10% of pleurisies remain unknown etiology. [less ▲]
