Introduction Acantholytic squamous cell (adenosquamous) carcinoma of the skin are relatively rare subtype of squamous cell carcinoma, usually found in elderly on sun-exposed areas of the skin, predominately head, neck and upper extremities. Incidence of metastasis is 2-14%. Case Outline A case of a 76-year-old male, with the signs of left-sided facial palsy and cervical mass on the same side, is presented. Five months prior to the visit, due to acantholytic squamous cell carcinoma, an excision of the ulceration of the superior third of the left auricle was performed. Patient underwent surgical treatment, after pathohistological and radiological confirmation of the infiltrative neck metastasis. Postoperatively, rapid locoregional progression of the disease was noted in the patient, with a lethal outcome. Conclusion Squamous cell carcinoma (including acantholytic subtype) with lesions bigger than 4 cm in size in auricular-temporal region, signs of deep tissue invasion, and lymphovascular and perineural invasion have higher local metastatic potential. More frequent oncological check-ups with radiological examination are necessary in detecting locoregional metastasis. © 2015 Serbia Medical Society. All rightsreserved.

Bacterial biofilm formation has been implicated in the high incidence of persistent otorrhoea after tympanostomy tube insertion. The aim of the study was to investigate whether biofilm formation on tympanostomy tubes depends on the genetic profile of methicillin-resistant Staphylococcus aureus (MRSA) strains. Capacity of biofilm formation on fluoroplastic tympanostomy tubes (TTs) was tested on 30 MRSA strains. Identification and methicillin resistance were confirmed by PCR for nuc and mecA genes. Strains were genotypically characterised (SCCmec, agr and spa typing). Biofilm formation was tested in microtiter plate and on TTs. Tested MRSA strains were classified into SCCmec type I (36.7 %), III (23.3 %), IV (26.7 %) and V (13.3 %), agr type I (50 %), II (36.7 %) and III (13.3 %), and 5 clonal complexes (CCs). All tested MRSA strains showed ability to form biofilm on microtiter plate. Capacity of biofilm formation on TTs was as following: 13.3 % of strains belonged to the category of no biofilm producers, 50 % to the category of weak biofilm producers and 36.7 % to moderate biofilm producers. There was a statistically significant difference between CC, SCCmec and agr types and the category of biofilm production on TTs tubes (p < 0.001): CC5, SCCmecI type and agrII type with a moderate amount of biofilm, and CC8 and agrI type with a low amount of biofilm. Biofilm formation by MRSA on TTs is highly dependent on genetic characteristics of the strains. Therefore, MRSA genotyping may aid the determination of the possibility of biofilm-related post-tympanostomy tube otorrhea. © 2015, Springer-Verlag Berlin Heidelberg.

Background/Aim. Nasopharyngeal carcinoma (NPC) is a relatively rare malignant disease, of which 80 000 individuals become ill around the world annually, which amounts to 0.7% of all carcinomas. The aim of this descriptive study was to analyze NPC incidence in Belgrade (the capital city of Serbia, with about 1.6 milion inhabitants) during the period 1991-2005. Methods. In data analysis, crude rates age and sex specific rates, and standardized incidence rates were used. Standardization was performed by a direct method, using world population as the standard. Results. In Belgrade, during the observed 15-year-period, the number of new NPC patients totaled 118, of which 86 (72.9%) were male and 32 (27.1%) were female. The average standardized incidence rate for men was 0.52 per 100 000 and for women 0.16 per 100 000. In both sexes the incidence was very low before 40 years of age. In men, the greatest incidence rate of NPC was in the 50-59 years age group, and in women in those 60 and more years old. Furthermore, undifferentiated carcinoma of nasopharyngeal type was 3.6 times more often in comparison to squamous cell carcinoma. Conclusion. Belgrade belongs to a region with a low incidence rate of NPC. Further investigations are needed to explain higher frequency of undifferentiated carcinoma of nasopharyngeal type than squamous cell carcinoma.

Introduction Acute otitis media is a very common disease in the early childhood age, with typical symptoms such as otalgia and fever. Otogenic complications are divided into extracranial and intracranial. Although the introduction of antibiotics has significantly reduced the incidence of intracranial complications, they are still present. Clinical picture usually develops fast, with the predominance of neurologic symptoms. Case outline An 11-year-old boy was admitted to a tertiary health care children’s hospital because of fever, agitation, altered behavior and disorder of consciousness. Based on the anamnesis, clinical examination, CT, MRI, and lumbar puncture, it has been established that it is a case of meningoencephalitis as complications of acute otitis media. Besides intense antibiotic and symptomatic therapy, surgical treatment too was conducted as well. Firstly, mastoidectomy with the implantation of ventilation tube was done, followed by radical tympanomastoidectomy, because there was no improvement. The treatment was followed by numerous complications, such as toxic hepatitis, mycoplasma pneumoniae infection, and hemolytic anemia. The treatment lasted for 71 days, and the patient was discharged from the hospital in a good general condition, without the focal motor failure. Conclusion Meningoencephalitis is unusual and rare complication of acute otitis media that requires urgent diagnostic procedure and multidisciplinary approach to the treatment. Surgical treatment of the ear that caused complications should not be postponed, and the choice of surgical method must be adapted to each patient individually. Hospital treatment of these patients is often prolonged and auditory and neurological sequelae are substantial and require long-term treatment. © 2019 Serbia Medical Society. All rights reserved.

Introduction The incidence rate of nasopharyngeal carcinoma in Serbia is less than one per 100,000 citizens, which classifies it as a region with low incidence for this disease. Objective The aim of this study was to test some hypotheses of the risk factors for undifferentiated carcinoma of nasopharyngeal type (UCNT) in the low incidence population. Methods A case-control study was used for the research. The study included 45 cases with histopathological diagnosis of UCNT and 90 controls. Cases and the controls were individually matched by sex, age (±3 years), and place of residence (city-village). Data were gathered about sociodemographic characteristics, occupational exposure to harmful agents, habits, diet, personal history, and family history. In the analysis of the data, conditional univariate and multivariate logistic regression analyses were applied. Results According to the results of multivariate logistic regression analysis UCNT was significantly positively associated with "passive smoking" of tobacco in the family during childhood, frequent consumption of industrially manufactured food additives for enhancing flavour and frequent consumption of white bread. UCNT was significantly negatively associated with frequent consumption of margarine, olive oil and cornbread. Conclusion In our low incidence population, an independent risk factor for the occurrence of UCNT was "passive smoking" of tobacco in the family during childhood, use of industrially manufactured food with additives for enhancing flavour and consumption of white bread. Multicentric study enrolling a greater number of cases would be desirable.
