[Sonography is coming to the forefront in musculoskeletal diagnosis complementing other imaging modalities. This field began to develop with ultrasound examination of the hip. We examined cases in three different age groups. In infants, various degrees of hip dysplasia were assessed. In small children, ultrasound assisted in diagnosing the cause of hip pain. In adults, ultrasound proved to be useful in differentiating inta- and extraarticular pathological processes. Our results demonstrate that, with experience, hip ultrasound examinations can be carried out with considerable accuracy. ]

[Malnutrition syndrome in childhood part I.]

BAKSAI László, PHILIP W. H. Eskes

[Malnutrition is a chrocic nutritional disorder resulting from insufficient intake of caloric energy and/or some the fundamental nutrients. Since it is the most common public health problem in the world it has a great impact on pediatric morbidity and mortality. The etiology is extremely complex. When one considers the less severe symptoms and signs caused by vitamin-, mineral-, and trace element deficiencies, it is apparent that not only children living in underprivileged countries are affected. In the course of making the diagnosis an assessment of the nutritional status should also be made, especially considering the above-mentioned marginal nutritional deficiencies. The most common manifestation of nutritional disorders is anemia, which is mostly caused by lack of iron, vitamin B12, folic acid and can be complicated by infections. Nutritional requirements can be affected by several drugs. That is why this medication-nutrition interaction has to be kept in mind during treatment. The interaction of malnutrition and infection is very important, primarily for three reasons: mechanisms by which infection complicates the metabolic and nutritional status of the host; importance of suboptimal nutritional status on susceptibility and severity of intercurrent infections; clinical and therapeutic implication of these interactions. ]

[The bleeding time]

BODA Zoltán

[The bleeding time is considered to be the best screening test for the detection of disorders of primary haemostasis. Despite a large number of bleeding time tests, the exact pathophysiological background of the prolonged bleeding time is unknown. The significance of the cellular (platelet) von Willebrand protein is emphasized. A sensitive method (Ivy) and standardized devices (Simplate) are suggested. Examination of the bleeding time in cases of von Willebrand disease and congenital or acquired thrombocytopathy is essential. Specific recommendations regarding the rational use of the bleeding time (diagnostic algorythm) are presented. ]

[P300 wave evoked by visual and acustic stimuli in parkinsonian patients with or without dementia]


[Authors analysed the relationship between cognitive function disturbance observed in patients with Parkinson's disease and clinical features of the disease. Relationship between the latency prolongation of the P 300 wave and the duration of substitution therapy, clinical form and severity of the disease (the Hoehn-Yahr stage) was examined. 75 randomly selected young patients with Parkinson's disease were divided in to two groups: one with and the other without dementia as determined by the Wechsler. Hunt and Mini Mental State tests. The latency of the P 300 wave using visual and acoustic stimuli was determinated. Significant prolongation of the latency of P 300 wave evoked both by visual and acoustic target stimuli was found in parkinsonian patients with dementia. Patients with dementia have longer duration of disease and substitution therapy. The akinetic-rigid form of the disease was more frequent in this group as well. A significant part of younger patients are chacarterised not only with motor but with cognitive function disturbance, too. Determination of the latency of P 300 wave helps to select these patients and to choose the adequat therapy. ]

The applications of transcranial Doppler in ischemic stroke


Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

Chronic cerebrospinal venous insufficiency - disease or misdiagnosis?

PÁNCZÉL Gyula, SZIKORA István, BERENTEI Zsolt, GUBUCZ István, MAROSFŐI Miklós, KOVÁCS Krisztina, RÓZSA Anikó, RÓZSA Csilla

Background and purpose - Former studies reported internal jugular vein stenosis in patients with multiple sclerosis. We aimed to evaluate if these venous stenoses were real and cerebral venous outflow of patients with multiple sclerosis differed from that of normal controls. Methods - 20 controls were prospectively investigated by angiography and duplex ultrasound. Seven patients with multiple sclerosis underwent angiography in other centers; we reviewed these registrations and performed venous ultrasound examinations. Results - Angiography displayed >50% stenosis of internal jugular vein in 19 controls (69±17% on the right and 73±13% on the left side) and <50% stenosis in 1 control (43.5% and 44.6%). All 7 patients had at least one-sided stenosis. The mean degree of stenosis was 63±16% on the right and 67±13% on the left side. There was no significant difference in the degree of stenosis between patients and controls. However, these “stenoses” disappeared if the contrast agent was injected at a catheter position below the orifice of the subclavian vein during venography. The venous flow volume was also similar between groups: 479.7±214.1 and 509.8±212.0 ml/min (right and left side) in the patients and 461.3±224.3 and 513.6±352.2 ml/min in the control group; p=0.85 and 0.98 (right and left). Color and power duplex imaging also revealed normal blood flow of the internal jugular vein in all patients and controls. Conclusion - The cerebral venous status of patients with multiple sclerosis and controls were similar. The angiographic “stenoses” were virtual, caused by the contrast dilution effect of the non-contrast blood stream of the subclavian vein.

[Ultrasound of the acute pediatric scrotum]

COLEY D. Brian

[Proper evaluation of the acute scrotum, like any condition, starts with a history and physical examination by an experienced clinician. Often this is all that is needed to arrive at an accurate diagnosis, which then allows prompt and appropriate treatment. However, the true nature of the underlying disease producing scrotal pain is not always clear, and the consequences of error (testicular loss) are undesirable. Ultrasound is the single most useful imaging tool for imaging the scrotum. While nuclear medicine studies can help assess blood flow, the combination of anatomic detail provided by modern ultrasound equipment and the ability to assess blood flow and perfusion with color Doppler makes ultrasound invaluable. Properly performed and interpreted, ultrasound provides very high sensitivity and specificity for acute scrotal conditions. Understanding of the conditions that produce acute scrotal pain in children will improve one’s diagnostic abilities. The most important diagnosis to consider is testicular torsion, since untreated this will result in testicular death. While testicular torsion can occur at any age, it is most common in the perinatal and peripubertal age groups. Torsion of a testicular appendage is a frequent cause of scrotal pain in prepubertal males. The sonographic findings can mimic epididymitis, but diligent and focused sonographic examination can make the diagnosis. Epididymitis typically affects postpubertal males, but can be seen in younger patients with functional or anatomic urinary tract anomalies. Sonographic evaluation of the post-traumatic painful scrotum can help to differentiate injuries that can be managed conservatively and those that require surgery. Less common causes of scrotal pain include hernias and hydroceles, vasculitis, and idiopathic edema. Understanding the characteristic sonographic features of these conditions allows the examining physician to make more accurate and confident diagnoses. It is hoped that this review article will help to promote this understanding.]

[The role of MRI in the diagnosis of tumours]


[Imaging is important in the evaluation of tumour detection, staging to determine the response to therapy, to follow the patient to find an early recurrent tumour. The ability to assess cancer spread has been revolutionized by advances of digital imaging modalities, such as digital ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). MRI is the method of choice for detecting and evaluating brain, spine, head and neck and musculoskeletal tumours, but it is complementary in the investigation of the thorax. US and CT remains the primary test for imaging the abdomen, while MRI plays a subsidiary role as a problem solving technique. In the evaluation of focal liver disease numerous prior reports have documented a superior performance of MRI compared to CT and US in the detection of primary and metastatic liver tumours. MRI is gaining more and more importance in imaging of the pelvis. Breast MRI is increasingly used as an adjunct to conventional imaging modalities. Several recent developments in MRI have altered the role of this imaging, and it is often the preferred choice among diagnostic tools for the detection and characterization of tumour cases.]

[The clinical pathology of prostatic carcinoma]

KISS Ferenc

[On the basis of the actual state of art, the main tasks of clinical pathologists in the diagnostics of prostatic carcinoma may be summarized as follows: Recognition and differential diagnosis of prostatic adenocarcinoma. Estimation of tumour prognosis by means of a reliable histological grading system and establishing the pathological stage. Checking the efficacy of (hormonal) treatment relying upon histological features. An increasing effort to a better understanding and diagnosis of premalignant changes (dysplasia, prostatic intraepithelial neoplasia). In favour of individual characterization of a tumour, one should utilize the attainable modern investigative methods.]
