OBJECTIVESThe aim of this study was to find out the correlation and evaluate the accuracy of labial minor salivary gland biopsy as a diagnostic tool in the multidisciplinary management of patients ...with Sjögren syndrome. MATERIALS AND METHODSPatients, referred to our outpatient office between January 2014 and December 2018 from a rheumatologist for biopsy examination, as part of the complex diagnostic plan for suspected Sjögren syndrome, were included in the current study. Each specimen was examined histomorphometrically by the pathologist to calculate the focus score describing the degree of salivary gland inflammatory infiltration. RESULTSFifty patients met the inclusion criteria. From the total number of patients, 39 presented with an established Sjögren syndrome by fulfilling the revised American-European criteria. From those, 27 had a positive lip biopsy. The remaining 12 patients from the total group, who were diagnosed with Sjögren syndrome based on the same criteria, had a negative lip biopsy. CONCLUSIONThe labial minor salivary gland biopsy is a valuable diagnostic tool to establish the diagnosis of Sjögren syndrome. However, a positive biopsy result must always be correlated with all the other diagnostic criteria to prove the exact diagnosis (Tab. 1, Fig. 4, Ref. 49).

OBJECTIVESAuthors evaluate the impact of intraprocedural complications on successful technical realisation and long-term clinical outcome of the uterine fibroid embolisation. BACKGROUNDThe uterine ...artery embolisation (UAE) has become an accepted treatment method for uterine fibroids. In general, the unilateral embolisation is considered to be insufficient due to poor clinical effect. METHODSOverall, 165 uterine artery embolisations were analysed (retrospectively-prospectively) in 163 female patients. Intraprocedural complications and their impact on the possibility to perform bilateral embolisationwere evaluated. In patients with unscheduled unilateral embolisation, short-term as well as long-term clinical effects were observed with mean follow-up period of 41 months. RESULTSThe bilateral uterine artery embolisation was possible in 95.7 % (95 %, CI 91.3-99.4 %) procedures. The unilateral embolisation was reported in 7 procedures (4.3 %, CI 1.2-8.3 %) and reasons were following: resistant arterial spasm in 4 patients (2.5 %, CI 0.7 %-5.3 %) and impossible catheterisation due to unfavourable anatomic situation in 3 patients (1.8 %, CI 0.3-4.1 %). Other complications, such as dissection and perforation, did not affect the successful technical realisation. The long-term clinical effect of unscheduled unilateral embolisation was reported in 5 patients. CONCLUSIONThe results of our series of unscheduled unilateral uterine fibroid embolisation had high long-term clinical success rate. In way of unscheduled unilateral embolisation, we recommend MRI follow-up and reintervention only in way of persistence or recurrence of symptoms with concurrent MRI finding of residual fibroids(Tab. 5, Fig. 3, Ref. 12).
Retroperitoneal abscess after abdominal and retroperitoneal surgery is a relatively rare but serious complication that most often occurs as a result of a healing disorder in the postoperative period. ...The incidence is not high, in the literature the cases are mostly reported as case reports with a serious clinical course, high morbidity and mortality. The most important factor of effective treatment, after successful diagnosis by CT examination is rapid evacuation of the abscess and retroperitoneal drainage, in which mini-invasive surgical or radiological drainage dominate as methods of choice. Surgical drainage, burdened by higher morbidity and mortality is considered the last resort after failure of mini-invasive methods. In our case report, we present a case of retroperitoneal abscess, arising as a complication after gastric resection, which was evacuated and drained primarily surgically due to unsuitability for radiological intervention.
The authors describe a rare but potentially severe, sometimes even life-threatening complication occurring after various invasive renal interventions. The cause that gives rise to a fistula formation ...between close branches of renal artery and vein is an injury of these vessels during resection of a localised renal tumour, renal biopsy, percutaneous nephrostomy, and even blunt injury of the kidney. Blood flows under pressure from renal artery, pushes the surrounding renal parenchyma open, and creates a cavity varying in size and shape. This pseudoaneurysm may communicate with the collecting system of the kidney, in which case it may lead to haematuria, one of the typical symptoms of arteriovenous fistula.
The authors observed this complication in 8 patients (6 males aged from 56 to 70, average 61.7, and two females aged 28 and 54). In 7 patients, the fistula developed after resection of a localised renal tumour, in one patient after percutaneous nephrolitholapaxy of a stone in the kidney. The fistulae manifested themselves between 7 an 21 days after surgery by massive haematuria in 4 patients and by intermittent macroscopic haematuria in 3 patients. In one patient the fistula was asymptomatic while the pseudoaneurysm at the place of pathological connection of renal veins was found during ultrasonographic examination after renal resection.
In all patients, the diagnosis of arteriovenous fistula and pseudoaneurysm of renal artery was achieved by ultrasonographic and/or CT examinations. The highest diagnostic value can be ascribed to digital subtraction renoangiography by Seldinger method that subsequently allowed active treatment by introducing an endovascular coil. By this method we cured 5 fistulae. In two patients, urgent nephrectomies were needed because of massive life-threatening haematuria. One of arteriovenous fistulae underwent spontaneous thrombosis.
The symptomatic arteriovenous fistula requires fast and precise diagnosis subsequently enabling efficient treatment. Endovascular manipulation is a method allowing the preservation of kidney affected by arteriovenous fistula with renal artery pseudoaneurysm (Fig. 7, Ref. 21).
To compare the manual and digital cephalometric analyses and to research a new procedure of analog cephalogram digitalization.
40 repeated measurements were used to evaluate the reproducibility and ...reliability of both methods. The analog x-ray was CHIRALUX2, the digital camera used was Canon PowerShot G5 and the digital tracing was done by Dolphin imaging version 10. The sample dispersion has been evaluated for each of the monitored cephalometric variables (SNA, SNB, ANB, PP/ML, inter-incisal angle and Wits). The difference of sample dispersion was tested (Morgan-Pitman). Four doctors processed 100 random analog cephalograms in total and evaluated them in a way established by Bland and Altman.
Validity and reproducibility of analyses carried out manually and digitally is in high mutual correlation and therefore the software analysis can fully substitute the manual method. The dispersion of values in repeated measurements was higher in manual method and therefore we consider the digital method more accurate (Fig. 4, Tab. 1, Ref. 15). Full Text (Free, PDF) www.bmj.sk.
Authors evaluated the effect of the WEB 2.0 environment on dental education and estimated the difference in retention of knowledge by cephalometric analysis in orthodontics between conventional ...education and off-line e-learning.
Five years of experience with complex web-based e-learning system allowed the evaluation by retrospective analysis and on-line questionnaire.
The results revealed the current trends in on-line behavior of students based on the WEB 2.0 innovative technologies like Ajax. Results confirmed an increasing number of resources with a rising frequency of e-learning materials.
The study confirmed that e-learning of the same subject is more efficient in immediate examination after the lecture with even better results after 12 and 24 months against the control group (Tab. 3, Fig. 1, Ref. 26).
Uterine artery embolization (UAE) has become a standard therapy in the treatment of symptomatic uterine myomas. The procedure is associated with a few complications. One of them is myoma expulsion. A ...32-year-old woman was sent to our hospital with diagnosed intramural myoma with dysmenorrhea and pressure symptoms. UAE was performed since the patient preferred conservative treatment. The procedure was without any complications. Three weeks after embolization, she was readmitted because of vaginal discharge and minor bleeding. We diagnosed expulsion of necrotic myoma and performed transvaginal resection. Four months later, the patient is symptom free. Expulsion of intramural myoma can be thus considered as definite treatment and not a complication of embolization therapy.
In this study, authors describe a rare case of a 40-year old patient with a history of chronic pancreatitis due to ethanol abuse, repeatedly hospitalized for intermittent bleeding into ...gastrointestinal tract (GIT). The sources of bleeding were pseudoaneurysms of the peripancreatic arteries (gastroduodenal artery, right hepatic artery) bleeding into GIT via pancreatic duct. This type of bleeding is referred as hemosuccus pancreaticus and belongs to a rare form of bleeding into upper GIT. Development of each pseudoaneurysm was monitored with a 6 month time interval. The diagnosis was established using endoscope, Doppler ultrasound and CT angiography. During the therapeutic process, while stopping bleeding, two different radiological interventions were used. In pseudoaneurysm of gastroduodenal artery, hemostasis was achieved using selective transcatheter arterial embolization (TAE) with steel coils. In the second intervention, a stent was inserted into vascular lesion. In the discussion, authors review the problems of hemosuccus pancreaticus, epidemiology, symptoms, diagnostic and possible therapeutic approaches (Fig. 3, Ref. 31). Full Text (Free, PDF) www.bmj.sk.
Authors submit their view on the possibility of performing a serious evaluation of professionalism of teachers of theoretical and clinical subjects, particularly at school of medicine. The authors ...compare their ideas with those of A.C. Orstein and D.U. Levine (1989). In conclusion they point out the extraordinary position of university teachers so-called clinicians in the system of pregradual and post-gradual education, and their evaluation. (Fig. 1, Ref. 15.)
