RESUMEN
This study aimed to assess the extent to which psychosocial and functional aspects are affected in orthognathic surgery patients. The Oral Health Impact Profile (OHIP-CRO14), Orthognathic Quality of Life Questionnaire and Self-Esteem (SE) Scale were used. The sample included 110 Caucasian subjects (73% females) aged 19-54 years. Fifty-five patients with dentofacial deformities were treated by combined orthodontic-orthognathic surgical treatment, and 55 others, matched by sex and age, were untreated controls without dentofacial deformities. In comparison with the untreated subjects, patients before surgery had a poorer quality of life, with the largest effect size in oral function (OF) and OHIP (average differences 8.0 and 14.7, respectively; p < 0.001; r = 0.65 and 0.63), while the lowest effect sizes were in awareness of facial aesthetics (AW) and SE. The treatment induced statistically significant changes in all psychosocial and functional aspects, mainly with a large effect size (p < 0.001; r = 0.48-0.78). The major effect size was a decrease in facial aesthetic concerns (FE; 7.6 ± 6.2; p < 0.001; r = 0.78), followed by a decrease in impairment of OF and OHIP (8.0 ± 7.1 and 16.6 ± 14.6; p < 0.001; r = 0.75). The lowest effect size was in the decrease in AW and increase in SE. After surgery, all aspects were similar to those in the untreated subjects. In conclusion, facial deformity raises many issues, primarily related to aesthetic concerns and functional impairment; however, orthognathic surgery manages to improve quality of life to be similar to that of the population without deformities.

INTRODUCTION: The aim of present study is to investigate the most common infection pathogen found in the postoperative wounds, following surgical treatment of oral and oropharyngeal cancer, in order to identify the most suitable antibiotic treatment. PATIENTS AND METHODS: We analyzed patients with squamous cell cancer of oral and oropharyngeal region. In patients who developed postoperative wound infection, wound swabs were taken from three different sites: the cannula, wounds on the neck and wounds in the oral cavity. RESULTS: In total 195 patients were included. The postoperative wound infection was detected in 115 patients (59%). In average, the swabs were taken 8 days after the surgery. The similar bacterial species from all three sites were detected in 24 patients (12,3%). In comparison, we found that there was statistically significant difference in the bacteria abundance from all three sites (p=0,031). There were significantly more bacteria in the wounds of the neck than cannula (p=0,007) and in the wounds in the oral cavity than cannula (p=0,002). No statistically significant difference between the wound on the neck and in the oral cavity was found. The most frequently isolated bacterial family was Enterobacteriaceae. Other more commonly isolated bacteria species were Staphylococcus spp. (G+), Pseudomonas aeruginosa (G-), Corynebacteruim spp. (G +) and Acinetobacter baumanii (G-). CONCLUSION: Based on the most commonly isolated groups of pathogens we concluded that probably the best empiric antibiotic treatment of wound infections until antibiogram is completed might be achieved from the group of aminoglycosides or quinolones. Antibiotic therapy should be reviewed if necessary when antibiogram is completed.

PURPOSE: The goal of this study was to identify risk factors for wound infections in patients with oral cancer who underwent surgical procedures. MATERIALS AND METHODS: This study included 195 patients who underwent surgical treatment of oral and oropharyngeal cancer over a 7-year period. Wound infection was defined as the occurrence of purulent content from the wound or as an appearance of exudate with signs of local infection and positive cultures taken from the wound. For every patient who was suspected to have a wound infection, a swab from the wound was taken, and microbiological analysis was performed. The patients were divided into 2 groups: patients with postoperative wound infections, and patients with postoperative wound infection. RESULTS: Wound infection was present in 155 patients (59%). Univariate analysis indicated that the following factors were significantly related to the occurrence of wound infection: gender, smoking, tumor localization, size and stage of the tumor, type of surgery, neck dissection, type of reconstruction, nasogastric sonde, gastrostomy and tracheotomy. On multivariate analysis, statistically significant predictors of wound infection were gender, tumor localization and type of reconstruction. CONCLUSIONS: The occurrence of wound infection is high despite antibiotic prophylaxis. To minimize the risk of wound infection and for prompt recognition of risk factors, surgeons managing oral tumor patients should have a better understanding of the risk factors such as gender, tumor localization and type of reconstruction.

INTRODUCTION: Osteopontin (OPN) is non-collagenous extracellular matrix protein involved in various physiological and pathological events, including tumor progression. The aim of this study was to analyze the expression of OPN in normal oral mucosa and oral squamous cell carcinoma (OSCC) and to assess its prognostic significance. METHODS: The expression of OPN was immunohistochemicaly analyzed in 86 OSCC and compared with clinicopathological variable such as tumor size, nodal stage, WHO clinical stage, Ki-67 proliferation index, and patients' outcome. OPN mRNA was analyzed using quantitative real-time PCR and compared with protein OPN expression and clinical outcome in 18 OSCC samples. RESULTS: The expression of OPN protein was found in OSCC tumor cells (t-OPN) and various stromal cells (s-OPN). High level of t-OPN expression was associated with higher nodal stage (P = 0.045), higher WHO clinical stage (P = 0.033), and poor clinical outcome (P = 0.022). In multivariate analysis, t-OPN emerged as an adverse independent factor for survival (P = 0.049). Although correlated with t-OPN (P = 0.005), s-OPN was not significantly associated with clinical parameters, including patients' outcome. Also, there was no association between OPN and clinical parameters at the mRNA level. CONCLUSION: OPN is upregulated in tumor and stromal OSCC cells. Tumor cell-derived OPN is involved in tumor progression and can independently predict the clinical outcome. Stromal-derived OPN probably has a different function compared with OPN secreted from tumor cells.

Patient underwent mandibular resection due to surgical therapy of oropharingeal malignoma. Facial asymmetry and cosmetic distortion are frequent consequences of such interventions, which may also include deviation and intrusion of the mandible, motor and sensory disorders, abnormal intermaxillary relations and malocclusion. Implant-supported prosthesis could be an optimal solution to prosthodontic treatment of such patients. However, there is a problem in determination of stable (interocclusal) intermaxillary relations. This article describes the choice of therapy and procedures undertaken in prosthetic rehabilitation of a patient who underwent mandibular resection and radiotherapy with supported prosthesis retained with four implants.

Smoking among pupils of secondary medical schools is of particular public health interest because of their role in the health system in the future. The study was part of the survey of smoking among students of Croatian medium medical schools. Data of 3 survey periods were available (1990-2002-2006). Specific smoking trends among 14-18 year olds were examined using odds ratios and multiple regressions. Sex ratios were calculated for each survey period. Daily smoking prevalence in 1990 was 15.9% in boys and 14.1% among girls. Occasional smoking in 1990 occurred among 8.9% of boys and 15.0% of girls. Twelve years after, smoking prevalence increased for daily smoking in boys to 32.9% and among girls to 30.4%. Occasional smoking decreased to 6.3% in boys, and increased to 17.8% among girls. There were no remarkable changes in prevalence from 2002 to 2006. Among adolescents in Croatia, there was high risk for smoking among adolescent population. High smoking rate among pupils of medical schools predicts not only high mortality due to smoking over 20-30 years, but also implicates for bad habit among professional health workers, if no policy interventions were taken.

Main objective of this study was to evaluate the usefulness and accuracy of fine needle aspiration cytology (FNAC) diagnosis of parotid masses to distinguish reliably between benign and malignant lesions. In the period of 5 years, 214 parotid glands were resected at the Rijeka University Hospital Center (Croatia), but 176 patients had cytopathological and histopathological diagnoses and therefore fulfilled the criteria for study. The results of the FNAC were analyzed and compared to the corresponding histopathological diagnosis obtained from the surgical specimen. Histological evaluation revealed 17malignant and 159 benign lesions. There were 13 true positive, 147 true negative, 3 false negative, and 13 false positive. Sensitivity of FNAC was 81%, and specificity was 98%. FNAC results provide useful predictive preoperative information and better preparation the surgeon and patient for surgical procedure.

OBJECTIVE: The purpose of this study was to investigate the outpatient utilization of cardiovascular drugs in Croatia, during the period 2001-2005, using the Anatomical Therapeutic Chemical classification of drugs/Defined Daily Dose (ATC/DDD) methodology. METHODS AND RESULTS: Data on outpatient drug utilization were obtained from the Zagreb Municipal Pharmacy to calculate the number of defined daily dose (DDD), and DDD per 1000 inhabitants per day (DDD/1000/day). The drug utilization 90% (DU90%) method was used on drug prescribing quality assessment. Data on hospital admissions were collected from the inpatient database kept at the Zagreb Institute of Public Health. Total utilization of cardiovascular drugs (ATC group C), was between 402.9 Defined Daily Dose per 1000 inhabitants per day (DDD/TID) and 362.9 DDD/TID in Croatia between 2001 and 2005. Agents acting on the renin-angiotensin system (C09) (104.2 DDD/TID) and calcium channel blockers (C08) (80.5 DDD/TID) accounted for more than 50% of drugs used for the treatment of hypertension in 2005. A great increase in the utilization was observed for statins (78.3%). A markedly increasing utilization was recorded for angiotensin-converting enzyme (ACE) inhibitors in combination with hydrochlorothiazide (HCTZ) (40.5%) and angiotensin II antagonists (278%). Comparison of the DU90% segment between 2001 and 2005 revealed pentoxifylline and amiodarone to be absent, whereas cilazapril and ramipril in combination with HCTZ, bisoprolol, valsartan and losartan alone or in combination with HCTZ were added in 2004 and 2005. The total rate of hospital admissions for major cardiovascular events decreased by 18.2%. CONCLUSION: The utilization pattern was improved in 2005, showing a decrease in the number of hospital admissions for major cardiovascular events.

INTRODUCTION: After all options of conservative treatment of trigeminal neuralgia have been exhausted, surgical methods are used. Peripheral neurectomy is one of the simplest among them. It is a relatively obsolete method, but can still be useful and effective. AIMS: To analyse the remission period after repetitive neuroexeresis of the same neural branch, to calculate "predicted" remission, and to evaluate the benefits of repetitive neuroexeresis. PATIENTS AND METHODS: Total of 85 neurectomies were performed in 36 patients in 5 years by intraoral access. The recurrence time was analysed by simple regression analysis, using the method of the least-squares. Thus, the average pain free time after repetitive neurectomy can be predicted. RESULTS: After the first operation on the infraorbital nerve, recurrence mainly appeared in the period between 12 and 15 months, after the second between 9 and 12 months. After the first operation on the mandibular nerve, recurrence took place mainly after 15-18 months, after the second 12.3 months on the average. No interventions were performed on the first branch. Calculated prediction of the average time of remission was in agreement with the actual duration of painlessness. CONCLUSION: Remission time after repetitive neurectomy decreases. There is no point in repeating the surgery on the same neural branch more than three times.

Number of researches dealing with the influence of the ABO blood group antigens on the development of the oral cancer have hypothesized that people who do not secrete these substances in the saliva are more prone to suffer from this disease. The objective of this research is to examine this hypothesis. In total 114 subjects were examined, half of which suffered from oral cancer, while the other half was the healthy control group. All examinees were subjected to clinical examinations and the experimental group to pathohistological examination. An analysis of the secretor status was carried out using the Wiener agglutination test. The experimental group consisted of 78.95% of secretors, while the control group consisted of 82.46% of secretors. This difference is not statistically significant. The starting hypothesis that non-secretors are more prone to the development of oral cancer was not confirmed.

Wound infection is a common complication after oral cancer surgery and may result in significant functional morbidity, poor cosmetic results and prolonged hospitalization. The purpose of this study was to identify the most important factors contributing to operative wound infections in patients with oral and oropharyngeal cancer. A retrospective review of complications in 111 patients after oral and oropharynx cancer surgery with an immediate reconstruction is presented. Potential risk factors for infection were categorized based on the patient, the disease, and the treatment. Flap-related complications developed in 73 patients (65.76%). Wound infection occurred in 69 (62.12%), and a fistula in 10 patients (9%). Other complications developed in 41.44% of the patients. The analysis of risk factors for the development of infection showed the following factors to be significant: male sex, T and S tumour stages, reconstruction, tracheostomy, nasogastric tube or gastrostomy feeding and extent of surgery.
