DECEMBER 21, 2009

Hungarian Radiology - 2009;83(04)

[INTRODUCTION - This audit was carried out to assess the usefulness of ultrasound in the diagnosis of adnexal torsion in pediatric and adolescent patients, and to demonstrate any ultrasound characteristics which are predictive of ovarian torsion in this population. PATIENTS AND METHODS - Retrospective review of ultrasound reports, operative reports, and medical records for 17 pediatric patients treated at BAZ-County University Hospital, Miskolc, was performed. The patients had presented to the pediatric surgery with complaints of abdominal pain between August 2000 and August 2008, and underwent an abdominal/pelvic ultrasound prior to going to the operating room for surgical management. All ultrasounds were categorized regarding the presence or absence of adnexal torsion. Other sonographic parameters included were: the mass size, description, and the presence of signs associated with adnexal torsion (presence and arrangement of ovarian follicles, presence of free fluid in the pelvis, and the presence or absence of arterial or venous flow by color Doppler to the ovaries). Surgical and pathological findings were also studied. RESULTS - All 17 patients in this review were surgically confirmed cases of torsion. 14 (82%) of the torsions occurred on the right side, 3 (18%) on the left side. Ultrasound described 8 adnexal masses with torsion as cystic (n=8, 47%). Pelvic fluid was present in nine patients (53%). Of 10 patients in which follicles were noted, follicles were observed to be peripherally displaced in seven (41%). Only two patients (12%) underwent laparoscopic surgery, remaining received open surgery. On evidence of torsion in the operating room, detorsion was performed in all cases. Finally, tubal cystectomy was performed in 2 (12%), ovarian cystectomy in four (24%), oophorectomy in two (29%), salpingooophorectomy in 6 cases (35%), and oophoropexy was performed in three cases (2%). The majority of pathology in those with confirmed torsion were hemorrhagic cysts in 10 cases (59%), paratubal cysts in three cases (18%), and teratomas in one cases (6%). No histologies were sent for three patients who received oopheropexy. 13 patients (76%) with torsion had adnexal masses greater 5 cm. The duration of complaints prior to treatment was also an important factor: Generally patients with more than one day long complaints underwent oophorectomy, exception to this was a case with intrauterine torsion. CONCLUSIONS - In our audit, patients with adnexal masses greater than 5 cms were more likely to have torsion than those patients with masses less than 5 cms.]

[Cervical space occupying lesions: diagnosis at sonoelastography]


[Among cervical (neck) region tumours, the thyroid lesions and the metastatic lymph nodes are the most detectable with conventional B-mode ultrasonography (US). The use of MRI and CT scans are limited because of the cost, and in case of CT, the radiation. With the introduction and constant development of sonoelastography, we have in our hands a new imaging procedure which is cheap, fast and harmless, yet giving more information to the examiner than conventional US. The elastographic examination of thyroid lesions is a more explored area than the elastographic visualisation of cervical lymph nodes. The ‘off-line’ elastography showed the highest accuracy allowing to calculate and analyse the strain index of cervical lymph nodes - strain index > 1.5 (85% sensitivity, 98% specificity) - but the ‘off-line’ processing of US elastograms is still too time consuming to be used in busy clinical settings. During the examinations of the thyroid gland both real-time and off-line processed strain imaging were used. An Italian team made a great leap forward as they standardized the degree of distorsion under the application of the external force. Then using the Ueno and Itoh elasticity score they achieved remarkable accuracy with real-time sonoelastography (P <0.0001). On the other hand only those organs are suitable for the US elastography characterization which can be slightly compressed, consequently the examination of a lesion with calcified shell cannot give useful information. Near to the pulsating arteries substantial amounts of decorrelation noise may appear and the examiner has to pay attention what structures are in the ROI box since the sonoelastography method assumes computations relative to the average strain inside the box. To detect a follicular carcinoma in the thyroid gland remains a big challenge. Despite of the limitations most researchers agree on the fact that sonoelastography is a perfect tool to use in addition to the conventional US examination. B-mode US combined with sonoelastography raised the accuracy in differentiation in all cases. With this modality it is also possible to deduce the number of cases when healthy lymph nodes or tissue peaces are taken for biopsy during FNAB.]

[Digital volume tomography - The use of cone beam CT in dentistry, oral and maxillofacial surgery]


[Oral and maxillofacial radiology is a subspecialty with its own field of indication. The goal is to achieve proper diagnostic image quality with the minimal amount of harmful radiation. The most common acquisition techniques are the intraoral radiograph and the panoramic radiograph which result in an overview picture of the whole dental status of the patient or the full mouth survey with the higher doses of radiation indicated for periodontological treatment. The next level is the supplementary radiograph such as occlusal radiograph, transversal tomography (some panoramic radiographs have this option), lateral cephalometric projection, submentovertex view or Waters projection, etc. More over cone beam CT acquisition or digital volume tomography as is called. In case of some described special indications CT, MRI or sometimes US acquisition can be made. In the field of three dimensional radio-diagnostics, the CT has a superior place with well-known advantages for everybody, and the usage has been limited only by the high radiation dose. The main point of the acquisition is the image quality. The load of radiation only makes the field of indication narrow. In every day practice - because of the higher radiation load of each high quality CT - the pictures passing to the doctor are preferred to take with lower resolution and wider slices although the diagnostic value of this never reaches the wanted level. This is why this new acquisition system also mentioned in the title would be better known. This system works with reasonable low radiation coupling with the possibilities of the high fidelity 3D imaging focusing on the bony structures of the head and neck region. The purpose of this article is to give a comprehensive introduction to this method in use for more than a decade. From 2006 in Hungary we also have the option to use the technology.]

[Voiding sonocystography with ultrasound contrast material for the diagnosis of vesicoureteral reflux]


[Voiding sonocystography with intravesical administration of ultrasound contrast agent is a sensitive method to detect vesicoureteral reflux without irradiation. Depicting microbubbles in the ureters and collecting system is feasible even with very small amounts of a second-generation ultrasound contrast agent, Sonovue. The reflux is graded (I-V) in a similar manner to the system used in voiding cystourethrography. In this article a detailed description is presented.]

[Measurement of therapeutic response during the primary systemic therapy of breast cancer]

TŐKÉS Tímea, SZENTMÁRTONI Gyöngyvér, LENGYEL Zsolt, GYÖRKE Tamás, DANK Magdolna

[Primary systemic therapy (PST), also called as neoadjuvant therapy has a substantial role in the treatment of patients with breast cancer. There is an increasing need among clinicians for the monitoring of therapeutic effectiveness. Beyond simple physical examination, diagnostic imaging tools have the most important role in the measurement of the therapeutic response. Selecting the appropriate imaging method is crucial for the correct evaluation of the therapeutic response and for planning further therapy. In this paper we review breast imaging modalities currently available in Hungary and detail the efficiency of these modalities in the evaluation of the therapeutic response.]

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]
