Central Hemangioma of the Mandible: Case Report

Autori opisuju centralni hemangiom donje čeljusti dijagnosticiran radiološki i patohistološki, a kirurški se postupak komplicirao zbog naknadnog krvarenja koje je zaustavljeno dodatnim kirurškim zahvatom. Kako je centralni hemangiom čeljusti dosta rijedak - što potvrđuje i navedena literatura – a moguće komplikacije kod te patološke promjene mogu biti izrazito opasne, svrha prikaza je istaknuti kliničke, radiološke i patohistološke karakteristike te tvorbe. Usporedba s drugim slučajem - koji je radiološki izgledao kao policističan tumor čeljusti, ali je tijekom zahvata počelo obilno krvarenje te je odgođen nastavak zahvata i indicirala se dodatna angiografska i radiološka obrada - pokazala je da nema karakteristične kliničke i radiološke slike koja bi mogla upozoravati na takve promjene. Raznolikost radioloških slika u svjetskoj literaturi upozorava da svaka transparencija u čeljusti među patološkim promjenama može biti i centralni hamangiom. Prikazani slučajevi potvrđuju takvo mišljenje.The authors present a case of central hemangioma of the mandible which was diagnosed radiographically and histopathologically. The surgical procedure was complicated by subsequent bleeding which was stopped by an additional surgical procedure. As central hemangioma of the jaws is a relatively rare findings, which can be observed from the relevant literature, and possible complications can be extremely dramatic, the aim of the presentation is to emphasise the clinical, radiographic and histopathological characteristics of this formation. Comparison with another case, which radiographically resembled a polycystic tumour of the jaw and which bled profusely during the operation, causing the postponement of the operation and indicating the need for additional angiographic and radiotherapy, demonstrated that there are no characteristic clinical and radiographic appearances which can indicate the possibility of such changes. The diversity of the radiographic appearances presented in the world literature shows that apart from other pathological changes any transparency in the jaws may also be a central hemangioma. The presented cases confirm this judgement

Calcifying Odontogenic Cyst – Gorlin’s Cyst – Report of Two Cases

The authors present two cases of calcifying odontogenic cysts, which were confirmed by histological examination. In the first case the radiographic findings and clinical status did not indicate the presence of a calcifying odontogenic cyst. In the second case, differential diagnosis included COC. The histopathological findings showed that what appeared to be simple cases of bone translucencies was in fact an unusual odontogenic lesion. The two cases point out the possibility of incorrect assessment of deceptively banal cases in daily specialist practice

Angiomyoma – Angioleiomyoma of the Cheek

The authors present the case of an angiomyoma – angioleiomyoma of the cheek in a 58-year-old man. The tumour was palpable, although clinically not visible, and the only case of a tumour of smooth muscle treated in the Clinical Department of Oral Surgery over the last 40 years. The operation was performed in the Outpatient Department by intraoral procedure. The postoperative course passed without complications. Current literature on leiomyomas is cited in the Introduction, followed by presentation of the case and histological characteristics of the tumour. The example is presented as a rarity and one of the differential diagnostic possibilities in the diagnostics of soft tissue tumours in the oral cavity

Possible factors for ankle fractures

Background/Aim. Classification of ankle fractures is commonly used for selecting an appropriate treatment and prognosing an outcome of definite management. One of the most used classifications is the Danis-Weber classification. To the best of our knowledge, in the available literature, there are no parameters affecting specific types of ankle fractures according to the Danis-Weber classification. The aim of this study was to analyze the correlation of the following parameters: age, body weight, body mass index (BMI), height, osteoporosis, osteopenia and physical exercises with specific types of ankle fractures using the Danis-Weber classification. Methods. A total of 85 patients grouped by the Danis-Weber classification fracture types were analyzed and the significance of certain parameters for specific types of ankle fractures was established. Results. The proportion of females was significantly higher (p < 0.001) with a significantly higher age (59.9 years, SD ± 14.2) in relation to males (45.1 years, SD ± 12.8) (p < 0.0001). Type A fracture was most frequent in the younger patients (34.2 years, SD ± 8.6), and those with increased physical exercises (p = 0.020). In type B fracture, the risk factor was osteoporosis (p = 0.0180), while in type C fracture, body weight (p = 0.017) and osteoporosis (p = 0.004) were significant parameters. Conclusion. Statistical analysis using the Danis-Weber classification reveals that there are certain parameters suggesting significant risk factors for specific types of ankle fractures

Treatment of Peritrochanteric Fractures by the Use of Gamma Nail

The Gamma nail was designed to treat unstable intertrochanteric and subtrochanteric fractures. In this study we analysed a total of 60 patients (44 men and 16 women), who were surgically treated for the peritrochanteric fracture in period 2006–2007 at the University Hospital Mostar. After the surgical treatment good bone healing was achieved in 50 patients (83.3%). A total of five patients had delayed healing or protrusion of the cervical screw, and in two patients nails were not appropriately distally locked. During the follow-up period a total of 7 patients died. The average operation time was 40 minutes, and the average blood loss was 400 mL, which is a comparable result with the previously published studies. In conclusion, although most of the peritrochanteric fractures treated at the University Hospital Mostar were fixated by gamma nail, the final decision regarding the operational technique should be left to surgeon’s judgment, since the efficacy of the treatment plan is highly dependent on experience of the operational team and surgeon’s operational technique

Characterization of ptc effect in batio(3)-ceramics as a special phase transition - fractal approach

The applications of BaTiO3-ceramics are very important and constantly increasing nowadays. In that sense, we analyzed some phenomena related to inter granular effects. We used experimental data based on Murata powders and processing technology. Our original contribution to Heywang-Jonker-Daniels inter-granular capacity model is based on thermodynamic fractal analysis applied on phase transition in ceramic structures. In this case, PTCR effect has a diffuse first-order phase transition character in a modified Landau theory-fractal approach. Its basic properties are considered. This is an original contribution as a bridge between theoretical aspects of BaTiO3-ceramics and experimental results

Arsenic removal from aqueous solutions by sorption onto zirconium- and titanium-modified sorbents

Arsenic reduction in drinking water can include treatment by adsorption, switching to alternative water sources, or blending with water that has a lower arsenic concentration. Commercial sorbents MTM, Greensand and BIRM (Clack Corporation) were modified with zirconium and titanium after activation. The modifications were performed with titanium tetrachloride and zirconium tetrachloride. The modified sorbents were dried at different temperatures. The sorption of arsenate and arsenite dissolved in drinking water (200μg L-1) onto the sorbents were tested using a batch procedure. After removal of the sorbent, the concentration of arsenic was determined by HG-AAS. Zirconium-modified BIRM showed the best performance for the removal of both arsenite and arsenate. Modification of the greensand did not affect arsenic sorption ability. Zirconium-modified BIRM diminished the concentration of total As to below 5 μg L-1
