Opis:
Here we present the pooled analysis of 2 case-control studies on the association of brain tumours with mobile phone use. Use of analogue cellular phones increased the risk for acoustic neuroma by 5%, 95% confidence interval (CI) = 2-9% per 100 hrs of use. The risk increased for astrocytoma grade III-IV with latency period with highest estimates using >10-year time period from first use of these phone types. The risk increased per one year of use of analogue phones by 10%, 95% CI = 6-14%, digital phones by 11%, 95% CI = 6-16%, and cordless phones by 8%, 95% CI = 5-12%. For all studied phone types OR for brain tumours, mainly acoustic neuroma and malignant brain tumours, increased with latency period, especially for astrocytoma grade III-IV.

Opis:
Extracellular matrix components of benign ovarian tumours (cystadenoma, adenofibroma, cystadenofibroma) were analysed. The investigated tumours contained twice as much collagen than control ovarian tissues. Significant alterations in mutual quantitative relationships between collagens of various types were observed. The proportion of type I collagen decreased and that of type III collagen increased. The accumulation of collagen was accompanied by a reduction in sulphated glycosaminoglycan content whereas the amount of hyaluronic acid was not changed. Dermatan sulphate was the most abundant glycosaminoglycan component. It is suggested that the accumulation of collagen (natural barrier to the migration of tumour cells) and underexpression of glycosaminoglycans/proteoglycans (binding some growth factors and interleukins) may exert an inhibitory effect on tumour growth.

Purpose: The aim of this retrospective study was to present the prevalence of early and late radiation-induced reaction and factors affecting its formation and severity in patients after adjuvant radio- or radiochemotherapy in salivary gland cancer. Material and methods: A total of 113 patients with early and 91 with late radiation-induced reaction, irradiated in 2006-2016 were enrolled in the study. The frequency of acute mucosal radiation-induced reaction, time of onset, intensity, healing time, as well as the incidence of late radiation-induced reaction from the skin and subcutaneous tissue were analyzed. Factors that could influence the development and intensity of reaction were identified. Results: Acute severity and the presence of late radiation-induced reaction do not affect overall survival. Dosage in the tumor bed site, as well as the dosage in the nodal region, affect the severity of the acute radiation-induced mucosal reaction. The severity of the early radiation-induced reaction is higher in men, more advanced patients (higher T and N+ in TNM classification), irradiated into a larger area, and those in whom two-dimensional planning and complementary chemoradiotherapy were applied. The late reaction of the skin and subcutaneous tissue was dominated by patients irradiated in the nodal regions and those with a higher intensity of early radiation-induced reaction. Conclusions: Supplementary radiotherapy or radiochemotherapy in salivary gland cancer is associated with acceptable toxicity which has no effect on overall survival.

Opis:
Introduction. A teratoma is a tumor developed of several different types of tissue, like hair, muscle, teeth or bone. Aim. Mature benign cystic teratomas are very rare in the salivary glands and just few cases were reported. Description of the case. A 13 years old female was presented to our dental clinic of Princes Basma Hospital in Irbid in north of Jordan, with a painless, insidious progressive swelling in left parotid region without any significant family and personal history. Parents were cancer phobic and nervous from the condition of their daughter, they were very confused. There was no pain or any history of trauma. It was present just inferior to left ear cartilage. The mass was of size 3x3cm, non-tender, fixed, soft to firm in consistency, having smooth surface. Conclusion. Teratoma in parotid region is an extremely rare entity. Lack of any pathognomonic feature, it is hard to diagnose preoperatively. Lumpectomy is advisable to remove the mass because the risk of damaging facial nerve in young patients and recurrence is rare. A definitive diagnosis is achieved after the histopathological study. Teratoma should be kept in account while evaluating a case of a soft tissue mass of parotid gland as a differential diagnosis.

Opis:
In order to understand better the role of the human Tip60 complex component Gas41, we analysed its expression levels in brain tumours and searched for possible interactors. Two-hybrid screening of a human foetal brain library allowed identification of some molecular interactors of Gas41. Among them we found n-Myc transcription factor. The interaction between Gas41 and n-Myc was validated by pull-down experiments. We showed that Gas41 is able to bind both n-Myc and c-Myc proteins, and that the levels of expression of Gas41 and Myc proteins were similar to each other in such brain tumors as neuroblastomas and glioblastomas. Finally, in order to identify which region of Gas41 is involved in the interaction with Myc proteins, we analysed the ability of Gas41 to substitute for its orthologue Yaf9 in yeast; we showed that the N-terminal portions of the two proteins, containing the YEATS domains, are interchangeable, while the C-terminal portions are species-specific. In fact we found that Gas41 C-terminal portion is required for Myc protein interaction in human.

Opis:
In this study plasma concentrations of IL-1α and IL-8 in 29 female dogs with malignant mammary gland tumours (19 without metastasis and 10 with metastasis) and in 10 healthy control animals were determined. Concentrations of IL-1α and IL-8 were analysed using a specific canine ELISA assay. Mean plasma concentrations of IL-1α and IL-8 were significantly higher (p<0.05) in female dogs with both non-metastatic and metastatic malignant tumours compared to the healthy animals. The concentrations of both tested cytokines were significantly increased (p<0.05) in the dogs with metastasis. In female dogs with mammary carcinomas, the plasma concentration of IL-1α was significantly higher (p<0.05) in the animals with grade 3 tumours compared to the dogs with grade 1 tumours. The concentration of IL-8 was significantly higher (p<0.05) in the dogs with grade 3 tumours compared to that found in the animals with grade 1 and grade 2 tumours. A moderate correlation (r=0.433) was found between IL-1α and IL-8 concentrations in the female dogs. These findings suggest that increased malignancy and invasiveness of canine mammary tumours is associated with an increased production of IL-1α and IL-8 in the tumour microenvironment, which, in turn, leads to an increase in their circulating levels. This may indicate that circulating levels of the cytokines investigated could be considered as diagnostic and prognostic markers in canine malignant mammary tumours. However, further studies in this fields are needed.

Opis:
Extracellular matrix metalloproteinases - MMPs, also referred to as matrixines, provide a group of proteolytic enzymes. They belong to the family of endopeptidases that break down elements of extracellular matrix, resulting in its continuous remodelling. Their activity is regulated at multiple levels, while tissue inhibitors of metalloproteinases play a major role in this process. Metalloproteinases play a significant part in neoplastic processes due to their contribution to local tumour invasion and formation of distant metastases, as well as to angiogenesis Urinary tract tumours pose a significant diagnostic and therapeutic challenge and their incidence tends to grow every year. The aim of this part of review is to describe extracellular matrix and matrix metalloproteinases and to highlight the contribution of matrix metalloproteinases in the development of renal clear cell carcinoma.

Opis:
Objective: Firstly, this review aims to analyse the recent literature about three-dimensional (3D) diagnostic imaging in complex and compound odontomas and compare it to two-dimensional (2D) imaging. Panoramic radiographs help to evaluate the vertical position of odontomas, and occlusal radiographs are used to evaluate the proximity to adjacent teeth. However, cone beam computed tomography (CBCT) can offer volumetric images, and therefore, a more accurate three-dimensional analysis. Secondly, this research aims to construct an open classification matrix for complex and compound odontomas for dentomaxillofacial CBCT radiology protocols based on a systematic literature review. Material and methods: Two systematic literature searches were conducted in PubMed (Medline), on 2 February 2022 concerning classification systems, and on 5 February 2022 concerning CBCT images. Results: In total, these searches revealed 391 papers by reviewing the databases mentioned above. Six articles were selected for inclusion on classification of odontomas and 13 articles were found on CBCT imaging. Consequently, the construction of an open classification matrix for compound and complex odontomas for dentomaxillofacial CBCT radiology protocols was performed using these 19 articles. Conclusions: CBCT offers a more precise position and accurate diagnosis of complex and compound odontomas compared to 2D imaging. Consequently, it enhances the detailed view of the site (multiple or unique), location (intraosseous, partially or completely extragnathic), size, extension (bony expansion, thinning or perforation cortical bone), density and type (denticulo type, particle type, denticulo-particle type, denticulo-amorphous type, amorphous tissue), relationship (with the crown or root of the definitive tooth), adjacent teeth resorption (deciduous or definitive), adjacent teeth (retention or impaction), and distance with adjacent structures (inferior alveolar nerve, sinus maxillaris), as well as adequate surgical planning. Moreover, this research presents an open classification matrix for the most complete description of compound and complex odontomas when analysing CBCT imaging.

Opis:
Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant hereditary disorder characterised by coexistence of pancreatic neuroendocrine tumours (pNETs) with parathyroid and pituitary tumours. PNETs, including mostly non-functioning tumours, gastrinoma and insulinoma, occur in nearly 95% of MEN1 patients and account for over 50% of disorder-related mortality. Therefore, early initiation of screening for pNET using biochemical and imaging tests as well as appropriate surgical and systemic treatment are of particular importance for this group of patients. Currently, there are no clearly defined guidelines which determine the optimal methods for detection and treatment of pNET in MEN1. Caution should be exercised when applying the guidelines designed for patients with sporadic pNET to MEN1 patients as the clinical course of the disorder is slightly different, involving multifocality of lesions and younger age of patients at onset. This paper discusses the distinctive features and challenges in diagnosing and treating pNETs in MEN1 patients.

Opis:
WSTĘP: Guzy wewnątrzkomorowe stanowią 1,5–3% wszystkich guzów mózgu. Są to zmiany o znacznej heterogenności pod względem rozpoznania histopatologicznego, symptomatologii oraz możliwych dostępów operacyjnych. Jednym z powikłań guzów wewnątrzkomorowych jest wodogłowie wymagające implantacji układu zastawkowego. Autorzy ocenili zależność rozwoju wodogłowia „zastawkozależnego” od lokalizacji guza, doszczętności resekcji, występowania wodogłowia przedoperacyjnego oraz zastosowania drenażu zewnętrznego komór mózgu. MATERIAŁ I METODA: Analizie retrospektywnej poddano 31 przypadków chorych z pierwotnie wewnątrzkomorowymi guzami mózgu, leczonych na Oddziale Neurochirurgii Szpitala w Jastrzębiu-Zdroju w latach 2002–2013. Wiek chorych wahał się od 17 do 75 lat. Grupa ta stanowiła 2,3% wszystkich pacjentów z guzami mózgu. Wybór dostępu operacyjnego był uzależniony od lokalizacji i charakteru zmiany oraz preferencji operatora. WYNIKI: 14 guzów (45,2%) położonych było w komorze czwartej, 9 (35%) w komorze trzeciej, 8 (25,8%) w komorach bocznych. Diagnostyka histopatologiczna wykazała: 6 przypadków ependymoma WHO II (19,4%), 4 subependymoma WHO I (12,9%), 3 carcinoma plexus choroidei WHO IV (9,7%), po dwa przypadki (6,5%) torbieli koloidowej i malignant ependymoma WHO III/IV oraz 10 innych rozpoznań. W 81% przypadków wykonano całkowitą resekcję guza. Wodogłowie przedoperacyjne występowało w 35% przypadków. U 42% chorych zastosowano drenaż komorowy zewnętrzny w okresie okołooperacyjnym. Wodogłowie pooperacyjne, wymagające implantacji układu zastawkowego, wystąpiło w 12,9% przypadków (4 chorych). Analiza statystyczna wykazała statystycznie istotną zależność jedynie między występowaniem takiego wodogłowia a lokalizacją guza (p = 0,041). WNIOSKI: Doszczętność operacyjna, obecność wodogłowia obturacyjnego przed zabiegiem oraz założenie drenażu komorowego zewnętrznego nie mają statystycznie istotnego wpływu na ryzyko rozwoju wodogłowia po zabiegu. Istotny statystycznie wpływ na powstanie „zastawkozależnego” wodogłowia w przebiegu pooperacyjnym ma jedynie lokalizacja guza z predylekcją do komory czwartej.
INTRODUCTION: Intraventricular tumours constitute 1.5–3% of all brain tumours. These tumours are a very heterogeneous group. There are many histologic types, various symptomatology and different surgical approaches. One of the possible complications is hydrocephalus, sometimes demanding shunt implantation. The authors estimated the relationship between shunt-dependent hydrocephalus and tumour location, the extension of resection, occurrence of preoperative hydrocephalus and the use of an external ventricular shunt. MATERIAL AND METHODS: A retrospective analysis of 31 cases with primary intraventricular tumours operated on in the Neurosurgical Department of the State Hospital in Jastrzebie-Zdroj between 2002 and 2013 was conducted. The age of the patients ranged between 17 and 75 years. This group constituted 2.3% of all patients with brain tumours. RESULTS: 14 tumours (45.2%) were located in the 4th ventricle, 9 (35%) in the 3rd ventricle, 8 (25.8%) in lateral ventricles. The histopathological diagnostics revealed: 6 cases of ependymoma WHO II (19.4%), 4 cases of subependymoma (12.9%), 3 cases of choroid plexus carcinoma, 2 coloid cysts (6.5%), 2 cases of malignant ependymoma WHO III/IV (6.5%) and 10 other diagnoses. Total resection was performed in 81% of tumours. Preoperative hydrocephalus appeared in 35% of cases. A perioperative external ventricular shunt was applied in 42% of patients. Shunt-dependent hydrocephalus appeared after 12.9% of operations (4 patients). Statistical analysis revealed a significant relationship between the existence of shunt-dependent hydrocephalus and tumour location (p = 0.041). CONCLUSION: The extent of resection, the occurrence of preoperative hydrocephalus and the use of an external ventricular shunt do not change the risk of the development of postoperative hydrocephalus. Only the location of the tumour has a statistically significant influence on the occurrence of shunt-dependent hydrocephalus.
