Pleomorphic adenoma - the results of a retrospective analysis of 104 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Laryngologic Oncology of the Military Institute of Medicine.

Pleomorphic adenoma, also known as tumor mixtus, is one of the most common types of benign neoplasm of the salivary gland, which presents as a slow growing, painless tumor. Major salivary glands are the typical localization of this neoplasm. It rarely undergoes malignant transformation, however may recur locally post resection. In this study, we present the results of a retrospective analysis of 104 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Laryngologic Oncology of the Military Institute of Medicine between 2004 and 2015 due to pleomorphic adenoma. The study confirmed the parotid gland as the most common location of tumor mixtus. In some cases, the large size of the tumor and its location were the cause of life-threatening complications.

Parotid gland tumors. Results of retrospective analysis of 149 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Oncologic Laryngology of Military Institute of Medicine in Warsaw in years 2006-2016.

Wstep: Nowotwory majace swoja etiologie w gruczolach slinowych wystepuja rzadko i stanowia ok. 3-10% wszystkich guzów w obrebie glowy i szyi. Material i metody: W latach 2006-2016 w Klinicznym Oddziale Chirurgii Czaszkowo-Szczekowo-Twarzowej Wojskowego Instytutu Medycznego w Warszawie z powodu nowotworów slinianek przyusznych hospitalizowano i leczono 149 pacjentów. Podstawa do analizy byly historie chorób pacjentów, wyniki badan histopatologicznych oraz protokoly zabiegów operacyjnych. Wyniki: W 126 przypadkach guzy byly lagodne, natomiast w 26 guzy zlosliwe. Analizujac wyniki mozna stwierdzic, ze nowotwory - zarówno lagodne, jak i zlosliwe - czesciej wystepowaly u mezczyzn. Sredni wiek calej grupy badanych wynosil 58,3 lat, dla zmian zlosliwych - 65,5 lat, a dla zmian lagodnych byl nieznacznie nizszy i wynosil 56,9 lat. Wsród pacjentów objetych analiza szczyt zachorowalnosci przypadal na przedzial wiekowy 60-69 lat. Ponadto zwraca uwage, iz przedzial ten byl taki sam dla ogólnej liczby guzów, jak i nowotworów lagodnych, natomiast dla nowotworów zlosliwych byl nieznacznie wyzszy i wynosil 70-79 lat. Z analizy zebranego materialu wynika, ze guzy lagodne wystepowaly znamiennie czesciej, stanowiac 84,56% wszystkich guzów. Najczestszymi rozpoznaniami wsród nowotworów lagodnych byly gruczolak wielopostaciowy (adenoma pleomorphicum) oraz gruczolak limfatyczny (adenolymphoma), które stanowily lacznie 93,66%. Rezultaty badan wskazuja, ze wsród nowotworów zlosliwych dominowaly: gruczolakorak polimorficzny o niskiej zlosliwosci (polymorphous low-grade adenocarcinoma) wystepujacy w 26,07% przypadków, gruczolakorak inaczej nieokreslony (adenocarcinoma NOS) oraz rak zrazikowokomórkowy (acinic cell carcinoma). Kazdy z nich stanowil po 13,04% rozpoznan. Jak wynika z przeprowadzonej analizy najczestsza metoda leczenia bylo leczenie chirurgiczne jako metoda stosowana samodzielnie. Wnioski: Uzyskane z retrospektywnej analizy dane koreluja z pismiennictwem krajowym i swiatowym.

[Chemical hazards when working with solvent glues]. / Zagrozenia substancjami chemicznymi podczas prac z klejami rozpuszczalnikowymi.

BACKGROUND: Solvent glues are used in a wide variety of industries, e.g., textile, footwear and rubber. The problem of workers' exposure to solvent vapors is rarely tackled within the area of occupational safety and health in small and medium-sized enterprises. MATERIALS AND METHODS: In order to assess exposure to solvents, organic solvents emitted by glues were identified in the samples of workplace air. The concentration of acetone, benzene, cyclohexane, ethylbenzene, n-hexane, methylcyclohexane, butyl acetate and toluene were determined. RESULTS AND CONCLUSIONS: The obtained results evidenced the presence of cyclohexane, ethylbenzene, ethylcyclohexane, heptane, n-hexane, o-xylene, methylcyclohexane, methylcyclopentane, butyl acetate and toluene in workplace air. The concentration of those compounds in workplace air was low, usually below 0.15 of MAC. At some workstations the presence of benzene was also observed. Occupational risk was assessed at workstations where gluing took place. It showed that the risk at those workstations was medium or low.

Temporal muscle flap in reconstruction of maxillo-facial tissues.

AIM OF THE STUDY: Presents our experience in reconstruction of postsurgical defects with use of temporal muscle flap. MATERIAL AND METHODS: In the years 1996-2010 we treated 10 patients with malignant neoplasms of maxillo-facial region. Following tumor removal the fascia-muscle flaps of temporal muscle were used for reconstruction. Temporal muscle flaps were applied in 5 cases for reconstructing the defect of eye socket tissue after extensive resections and in the other 5 patients was used for reconstructing the defect of palate following maxillary resections. RESULTS: All the flaps of temporal muscle that were used for reconstructing eye sockets incorporated with no local reaction. In one case of flap applied into the oral cavity for tightly separate from nasal, partial necrosis of flap's edge and oro-nasal fistula occurred. CONCLUSIONS: Fascia-muscular flap of temporal muscle is a simple, easy and effective method of tissue reconstruction in maxillo-facial region following extensive oncologic procedures.

[Face cancer infiltrating of ethmoid-orbito-nasal complex]. / Raki plaskonablonkowe skóry twarzy naciekajace masyw nosowo-sitowo-oczodolowy.

Face cancer is one of the most common skin tumors and because of its locations is usually early diagnosed. In spite of this a lot of recurrence after surgical treatment are observed. It is caused a lack of proper margins in sequence of limitation excision because of esthetic and functional reasons. The recurrence of skin cancer primarily localized in periocular region and infiltrating intraorbital, ethmoidal and nasal tissues demand extensive and injurious surgical procedures. The authors present their experience in diagnostic and treatment patients with recurrent cancers infiltrating of ethmoid-orbito-nasal complex.

[Exposure to metal compounds in occupational galvanic processes]. / Narazenie na zwiazki metali w przemyslowych procesach galwanicznych.

BACKGROUND: Occupational galvanic processes are provided in more than 600 small and medium enterprises in Poland. Workers who deal with galvanic coating are exposed to heavy metal compounds: tin, silver, copper and zinc. Some of them are carcinogenic, for example, hexavalent chromium compounds, nickel and cadmium compounds. MATERIAL AND METHODS: Research covered several tens of workstations involved in chrome, nickel, zinc, tin, silver, copper and cadmium plating. Compounds of metals present in the air were determined: Cr, Ni, Cd, Sn, Ag--by atomic absorption spectrometry with electrothermal atomization (ET-AAS) and Zn--by atomic absorption spectrometry with flame atomization (F-AAS). RESULTS: The biggest metal concentrations--of silver and copper--were found at workstations of copper, brass, cadmium, nickel and chrome plating, conducted at the same time. Significant concentrations of copper were found at workstations of maintenance bathing and neutralizing of sewage. The concentrations of metals did not exceed Polish MAC values. MAC values were not exceeded for carcinogenic chromium(VI), nickel or cadmium, either. CONCLUSIONS: In galvanic processes there was no hazard related to single metals or their compounds, even carcinogenic ones. Combined exposure indicators for metals at each workstation did not exceed 1, either. However, if there are even small quantities of carcinogenic agents, health results should always be taken into consideration.
