[Polycystic ovarian syndrome is a heterogenous syndrome with a wide variety of endocrine and metabolic abnormalities and clinical symptoms. It is considered as the most frequent endocrine disorder in women in reproductive age and the most common cause of anovulatory infertility. Key features include menstrual cycle disturbance, hyperandrogenism and obesity. There are many extraovarian aspects to the pathophysiology of polycystic ovarian syndrome, but ovarian dysfunction is central. The underlying unique feature of the ovarian morphology gives the significance of the ultrasound examination. At a recent consensus meeting, a refined definition of the polycystic ovarian syndrome was agreed, encompassing a description of the morphology of the polycystic ovary. The subjective appearance of polycystic ovary should not be substituted for the definition. Further, a woman having polycystic ovary in the absence of menstrual disorder or hyperandrogenism (asymptomatic polycystic ovary) should not be considered as having polycystic ovarian syndrome, until more is known about the situation. Since ultrasound description of polycystic ovary morphology has central role in the diagnosis, and untreated polycystic ovarian syndrome carries long term health risks, the increasing attention to ovarian morphology may offer an effective tool to decrease women`s morbidity. This review outlines the background and feature of ovarian morphology in polycystic ovarian syndrome, and details the current ultrasound definition of polycystic ovary.]

[Results of non-operative pathological breast diagnostics - One year experience at the Bács-Kiskun County Teaching Hospital]


[INTRODUCTION - Non-operative cytological and histopathological assessment of breast lesions are part of the triple (physical, imaging and pathologic) diagnostic approach and allow a more precise planning of surgical procedures. Both methods have advantages and disadvantages; currently, core biopsy is believed to be more efficient in reaching the diagnostic target. PATIENTS AND METHODS - Breast specimens with a histological diagnosis at the Department of Pathology of the Bács-Kiskun County Teaching Hospital were analysed for their preoperative pathology, using the conventional C1-5 and B1-5 diagnostic categories. RESULTS - 295 cytology and 130 core needle biopsy cases were analysed. The rate of non diagnostic (C1 and B1) material was higher for cytology (0.18 versus 0.08 in general; 0.09 versus 0.01 for malignant cases). The rate of cases with an uncertain diagnostic category (C3 and C4 or B3 and B4) was also higher for the cytology specimens (0.24 versus 0.07). False-negative and false-positive cases were rare, but still more frequent among cytology specimens. CONCLUSION - Core needle biopsy performs better than fine needle aspiration cytology in the establishment of a nonoperative diagnosis at our institution. Despite these results, cytology continues to be the first diagnostic choice, because of its relatively low costs.]

[Breast core needle biopsies yielding uncertain results - Experience at the complex mammographic screening unit in Kecskemét]


[INTRODUCTION - On occasion core biopsies yield an inconclusive (B3 or B4) result in the triple diagnostics of breast lesions. These cases may turn to be malignant in the operation specimen. This study evaluates the value of B3 and B4 diagnoses and the consequences of these diagnoses. MATERIALS AND METHODS - Core needle biopsies were generally taken under imaging guidance with an automatic gun using G14 gauge needles. They were evaluated using internationally and nationally accepted categories from B1 to B5. The analysis was based on data collected between 2000 and March 2005. RESULTS - Of the 663 core needle biopsy specimens 31 (4.7%) were classified as B3 and 22 (3.3%) as B4. Specimens were more often fragmented in the latter category (a rate of 0.64 as compared with a rate of 0.26). Patients with a B3 diagnosis were operated on in 23 cases, eight of which turned to be malignant (0.35). B4 diagnoses were followed by operations in 21 cases and were found to be malignant on 19 occasions (0.9). Whenever a B4 diagnosis was associated with radiological findings of malignancy (category 5 on mammography and/or ultrasound) the cases unanimously proved to be malignant. The same association with B3 diagnoses yielded malignancy in a rate of only 0.67. CONCLUSION - Both B3 and B4 diagnoses represent an indication for operation. Our experience suggests that B4 diagnoses when coupled with a radiological opinion of malignancy can be candidates for definitive (therapeutic breast conserving) surgery whereas B3 diagnoses require diagnostic excisions.]

[The glove-finger phenomenon on postero-anterior chest radiograph]

SZÁNTÓ Dezső, SZŰCS Gabriella, DITRÓI Edit

[INTRODUCTION - The glove-finger phenomenon observed on chest plain film is characterized by branching tubular or fingerlike opacities that originate from the hilum and are peripherally directed. This change brings about impaction and inspissation of the mucus and inflammatory debris besides the obstruction of bronchi and of its prestenotic dilatation about. CASE REPORT - A 51 year old male patient presented with coexisting bronchial asthma and microcellular carcinoma of left 2nd pulmonary segment, leading to a tubular type glovefinger phenomenon. The diagnosis was proved by decrease of Tiffeneau’s index, bronchoscopy, bronchocytology and bronchogenic biopsy. CONCLUSION - The glove-finger phenomenon is correctly visible on postero-anterior chest plain film. The dilated and mucus-filled bronchi are not visible on radiography if the sorrounding lung is atelectasic. Because obstructive and nonobstructive bronchogenic diseases can appear with similar presentation, therefore, definitive diagnosis is only possible on the basis of pneumodynamic examinations, bronchoscopy, bronchocytology and biopsy.]

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.

[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.]

[Significance of ultrasound examination in acute abdominal attack of hereditary angioneurotic oedema]

FARKAS Henriette, HARMAT György, KAPOSI N. Pál, KARÁDI István, FEKETE Béla, FÜST György, FÁY Kálmán, VAS Anikó, VARGA Lilian

[INTRODUCTION - Hereditary angioneurotic oedema (HANO) is a rare cause of ascites. As acute abdominal attacks of the disease can mimic surgical emergencies, the prompt and accurate diagnosis is essential. This study was undertaken to evaluate the usefulness of abdominal ultrasound examinations in the differential diagnosis. PATIENTS AND METHODS - Seventy patients with HANO were followed up for almost a decade. All patients presenting with an acute oedematous attack underwent abdominal ultrasound, which was then repeated 24 and 48 hours after appropriate therapy. RESULTS - 22 patients with acute oedematous attacks with abdominal complaints severe enough to justify hospital admission occurred in the study population. Abdominal ultrasound performed during the attack showed oedematous thickening of the intestinal wall in 80 per cent of cases and invariably demonstrated the presence of free peritoneal fluid in all patients. Rapid symptomatic relief achieved by treatment was accompanied by the significant regression of ultrasound abnormalities. CONCLUSIONS - Demonstration of transitory ascites by abdominal ultrasound is a clue to the diagnosis of an acute abdominal attack of HANO. The possibility of HANO should always be considered whenever unexplained abdominal pain returns with or without ascites.]
