Abstract
Extramedullary plasmacytoma (EMP) of the orbit is an extremely rare tumor, which frequently manifests with nonspecific symptoms. In the case reported, the symptoms of relapsing dacryocystitis appeared before the diagnosis of orbital EMP in a 60-year-old man. Moreover, EMP of the right submandibular gland that had been excised and treated by radiotherapy preceded the orbital lesion by seven years. The present report emphasizes the importance of an extensive medical workup to rule out multiple myeloma or other malignant lymphoproliferative diseases, because their treatment and prognosis are very different. Additionally, it is necessary to consider all tumors that can provoke relapsing dacryocystits.

Abstract
OBJECTIVE We sought to evaluate the effects of awareness of rhinomanometric results on subjective sensation of nasal breathing in patients after septoplasty. DESIGN Prospective randomised study. SETTING Clinical Hospital Rijeka. PARTICIPANTS A study of 60 patients (45 M, 15 F) who underwent septoplasty was performed at the ENT Clinic, Clinical Hospital Rijeka. The patients were randomised into two groups; group A was shown their rhinomanometry scores at 3 months postoperatively, while group B remained unaware of their rhinomanometry results. MAIN OUTCOME MEASURE The assumption is that in the same settings patients aware of their rhinomanometric results have better performances of their Nasal Obstruction Symptom Evaluation (NOSE) scale and thereby a better quality of life (QOL) after septoplasty. RESULTS The differences in rhinomanometric results and NOSE scale prior and after septoplasty were statistically significant (P < 0.001), all patients achieving better results after the operation. There was no statistically significant difference in resistance (F = 0.004; P = 0.948) and improvement of rhinomanometry results in postoperative measurements (F = 0.110; P = 0.896) between groups A and B. The symptoms measured by the NOSE scale were the same in both groups preoperatively and 1 month after septoplasty (F = 2.906; P = 0.094). Three months postoperatively in group A, the NOSE scale score was lower (M = 11.67; sd = 12.34) than in group B (M = 27.50; sd = 18.04). CONCLUSIONS The results suggest that disclosing information to patients about their post-septoplasty rhinomanometry results may improve subjective nasal breathing, and thus improve their QOL.

Abstract
OBJECTIVES To determine minimum airflow rate required for olfactory stimulation in successfully rehabilitated laryngectomised patients after learning the polite yawning technique (PYT) and to confirm the hypothesis that sense of smell is rehabilitated once the nasal airflow is re-established. DESIGN Prospective open interventional trial. SETTING Tertiary academic hospital. PARTICIPANTS The study population comprised 100 laryngectomised patients. The control group consisted of 100 non-laryngectomised patients of similar age and sex. Rhinomanometry was used to measure air flow in the right and left nostrils, respectively, while the Smell Diskettes Olfaction test (SDOT) was used to test each individual's sense of smell. MAIN OUTCOME MEASURES The primary endpoint was increasing the airflow, while the secondary endpoint was improvement in the Smell Diskettes Olfaction test score after learning the polite yawning technique. RESULTS The difference in the Smell Diskettes Olfaction test results before and after introducing the polite yawning technique was statistically significant (F = 53.077; P < 0.001). The number of accurately identified odours increased with each measurement. There was a significant difference among rhinomanometric measurements of airflow through the right (F = 65.002; P < 0.001) and left nostrils (F = 75.465; P < 0.001). Nasal airflow improved with each measurement. The minimum airflow required for olfactory stimulation in successfully rehabilitated patients was approximately 60 cm(3) /s. The control group had considerably better airflow in both nostrils than the laryngectomised group. The difference between the total number of rehabilitated (normosmic) patients (48%) in the laringectomised group and normosmic participants (56%) in the control group (z = 1.132; P = 0.129) was not statistically significant. CONCLUSION The number of odours identified by laryngectomised patients increased with the volume of nasal airflow. The number of patients with rehabilitated olfactory function approximated the percentage of normosmic individuals in the non-laryngectomised population. These findings confirm the hypothesis that sense of smell is rehabilitated once the nasal airflow is re-established.

Abstract
OBJECTIVE To corroborate the result of postlaryngectomy olfactory rehabilitation evaluating the efficacy of the Polite Yawning Technique (PYT) with rhinomanometry and odours with the Smell diskettes Olfaction test (SDOT). MATERIALS AND METHODS Thirty-two laryngectomised patients were subjected to olfactory rehabilitation consisting of 15-minute training and independent exercising for two weeks. The sense of smell and nasal airflow in laryngectomised patients were examined before and after implementation of PYT. RESULTS The differences in SDOT results prior to and after introduction of PYT were statistically significant, most patients achieving better results after rehabilitation. A significant positive correlation was obtained in results of SDOT and rhinomanometry prior to and after introduction of PYT. The results of measurements after rehabilitation showed that 75% of patients had improved nasal breathing, 78% of patients had a better sense of smell and 40% of patients became normosmic. CONCLUSIONS PYT has proved to be an effective method in olfaction rehabilitation following total laryngectomy. Using rhinomanometry, evaluation of the rehabilitation success is substantiated while the technique is simplified.

Abstract
AIM To evaluate the importance of epidermal growth factor receptor (EGFR) protein overexpression and gene amplification in carcinogenesis of glottic cancer. METHOD In order to evaluate EGFR expression at protein and gene level, immunohistochemical (IHC) analysis and fluorescent in situ hybridization (FISH) were performed on tissue microarrays of laryngeal tissue (145 samples) -- 38 samples of normal mucosa, 46 samples of hyperplastic lesions, and 61 samples of cancerous lesions. RESULTS Membranous (mEGFR) and cytoplasmic (cEGFR) EGFR expression was significantly different between the analyzed groups. The differences were most striking in the suprabasal-transforming zone. IHC evaluation showed that high and low mEGFR staining contributed to the differentiation of dysplastic lesions, simple hyperplasia, and cancerous tissue, as well as between different degrees of atypia in hyperplastic lesions (P<0.050). EGFR gene amplification was not found in simple and abnormal hyperplastic lesions, but it was confirmed in 2/21 atypical hyperplasias, indicating that gene amplification can facilitate identification of malignant potential in hyperplastic lesions. In cancerous tissue, EGFR gene amplification was found in 8/50 samples. EGFR gene amplification was found in preinvasive cancer in one patient. In invasive carcinomas, gene amplification was not associated with stage or grade. Carcinomas with gene amplification showed significantly higher cEGFR expression (basal layer P=0.003; suprabasal layer P=0.002). CONCLUSIONS This study confirmed an increase in EGFR protein expression and gene amplification with the increase in biological aggressiveness of glottic lesions. A correlation between EGFR gene amplification and protein expression was established. Gene amplification proved to be an early event in glottic carcinogenesis, indicating its importance for glottic cancer prevention, early detection, and protocol selection.

Abstract
OBJECTIVES To assess the suitability of a new anatomic model of the paranasal sinuses for endonasal surgical training. STUDY DESIGN Prospective observational pilot study. METHODS A new anatomic model of the paranasal sinuses was developed by the Department of Anatomy at the University of Zurich. The practicability of the model was evaluated by three experienced endoscopic sinus surgeons with a special focus on its possible use in training. Standardized surgical procedures were performed under simulated real-life conditions in the operating theatre. RESULTS The endoscopic appearance of the nasal airway closely resembled real human tissue and the detailed anatomy of the model allowed the same structured surgical steps to be performed as in real life in the absence of bleeding. CONCLUSION This anatomic model is a readily available teaching tool for endoscopic sinus surgeons.

Abstract
BACKGROUND Perioperative antibiotic prophylaxis has significantly reduced wound infection rates in clean-contaminated head and neck surgical procedures but controversy still remains regarding the optimal antibiotic regime. OBJECTIVE To examine the efficacy of different antibiotics in head and neck oncological surgery prophylaxis. PATIENTS AND METHODS In this prospective, double-blind clinical trial, 189 patients with carcinoma of the upper aerodigestive tract were randomized to receive amoxicillin-clavulanate or cefazolin intravenously up to 1h before surgery and at 8-h intervals for an additional three doses. RESULTS An overall wound infection rate of 22% was observed. The infection rate in patients receiving cefazolin was 24% (22/92) vs. 21% (20/97) in those receiving amoxicillin-clavulanate; the difference was not statistically significant. Postoperative overall non-wound infection developed in 12% (22/189) patients; the rate of infection was 9.8% (9/92) in patients receiving cefazolin vs. 13.4% (13/97) in those receiving amoxicillin-clavulanate, without a statistically significant difference between the two groups. Gram-negative bacteria were more often isolated with Pseudomonas aeruginosa as the dominant species. The risk of postoperative infection was more influenced by the type of surgical procedure than by disease stage. CONCLUSION In clean-contaminated head and neck oncologic surgery amoxicillin-clavulanate prophylaxis was at least as efficient as cefazolin. However, when taking into account the fact that beta-lactamase containing strains have recently been spreading, amoxicillin-clavulanate should be the logical first choice.

Abstract
We present a case of a 67-year-old female patient having a pleomorphic adenoma of epipharynx with intact fibrous capsula, which despite its benignity recurred and, moreover, responded quite well to irradiation therapy. The patient, at first, refused any therapy. Three years later, when the CT showed tumor enlargement she accepted only irradiation therapy, resulting in significant reduction of tumor size. Five years later the tumor recurred but without malignant transformation. She still refused surgery, but accepted re-irradiation therapy. After a three-year follow-up the patient has no symptoms of the tumor enlargement. This case shows that the irradiation therapy might be quite effective in the treatment of pleomorphic adenoma of epipharynx, but it is clear that much better results could be accomplished in combination with the surgery. In cases when the surgery is rejected or not possible because of the vicinity of the vital structures, we recommend the irradiation therapy as a therapy of the choice.

Abstract
AIM To define phenotypic characteristics of cytotoxic T lymphocytes (CTL) and natural killer cells (NK) in peripheral blood, frequency of somatic symptoms, and level of anxiety and depression in 25 patients clinically diagnosed with chronic post-traumatic stress disorder (PTSD). METHODS Patients were divided into two sub-groups according to the stressor: 18 PTSD patients with the battlefield experience and 7 PTSD patients with battlefield experience who were tortured as the prisoners of war (POW) in Bosnian-Serbian camps. The control group consisted of 15 healthy volunteers matched to the patients by sex and age. We tested all patients using Becks depression inventory, Spielberger anxiety test, and somatic disturbance list, and analyzed their peripheral blood lymphocytes using flow cytometry with the double fluorescence staining of cell surface antigens (CD3, CD4, CD8, CD16, and CD56) and intracellular cytolytic molecule perforin (P), a mediator of cytolytic action at the molecular level. RESULTS All PTSD patients showed a significant level of anxiety, depression, and numerous somatic symptoms. The only significant difference between PTSD patients with and without POW experience was in the anxiety level (median, 71; range 61-79; vs median, 65; range, 49-77). PTSD patients with POW experience had significantly higher levels of CD16+ cells (median, 37%; range, 16-55%) than those without it (median, 12%; range, 5-37%). Double labeling for intracellular P antigen and cell surface antigens showed the highest levels of CD16+P+ (median, 33%; range, 15-40%; vs median, 10%; range, 3-29%) and CD56+P+ (median, 21%; range, 11-40%; vs median 8%; range, 1-30%) cells in PTSD-POW patients. CONCLUSION Chronic PTSD patients who survived concentration camps show the most numerous alterations in PBL phenotype, the highest number of perforin-containing cells, and a significantly higher level of anxiety.

Abstract
OBJECTIVE To determine whether a patient with a serious defect of the tympanic membrane (TM) will be able to dive after surgery. PATIENTS AND METHODS The authors describe three patients who were divers with serious defects of the TM (more than 75% of TM). In all three cases, cartilage palisade tympanoplasty was used to reconstruct the TM. RESULTS Six months after surgery, the patients passed clinical examinations, audiograms (hearing restored to normal), tympanometry (increased stiffness of the TM), and pressure tolerance tests in hyperbaric chamber (30-m immersion was simulated for 4 minutes), and they began to dive again. Approximately 2 years after the surgery, all three patients are able to dive without any difficulties. CONCLUSION The authors conclude that patients can dive after cartilage palisade tympanoplasty.

Abstract
Acoustic brainstem response (ABR) waveforms were preoperatively analyzed in 86 cases of pontocerebellar angle (PCA) tumors. Absolute (APL) and interpeak latencies (IPL) ipsilateral to the tumor and interaural absolute latency differences of wave V (IAAPLD V) were normal in two patients with small intracanalicular tumors. However, results of latency-intensity studies were abnormal. So, if PCA tumor is suspected, and standard ABRs are normal by usual criteria, the latency-intensity functions should be examined before the test result is reported as negative for an acoustic nerve tumor.

Abstract
This retrospective study analyses the outcome of treatment of 61 patients with advanced carcinoma of the pyriform fossa. Thirty-two patients (group 1) underwent surgery and postoperative radiotherapy and 29 patients (group 2) had induction chemotherapy followed by radiotherapy. The local recurrence-free survival at 5 years from the completion of therapy for group 1 was 54%, compared to 61% for group 2. The 5-year neck recurrence-free survival for groups 1 and 2 were 54% and 59%, respectively. The 5-year overall survival rates for groups 1 and 2 were 19% and 14%, respectively. Non-surgical therapy for advanced stage pyriform fossa cancer provides survival comparable with that achieved with the standard approach of surgery and postoperative radiotherapy. We advocate radical irradiation as the method of choice because it provides nodal coverage to the bilateral jugular chains and retropharyngeal nodes, all known to be at risk for metastases, and is associated with lower morbidity compared to surgery. But, however, despite the therapy, the outcome is poor.

Abstract
We report a case of lethal midline granuloma in a 34-year-old male patient. The patient was referred to our hospital because of long-lasting hoarseness. He was treated for granuloma laryngis. After two years nasal obstruction developed followed by ulceration of the hard palate and destruction of part of the nose and the upper lip. A biopsy demonstrated polymorphic infiltrate consisting of small lymphocytes, plasma cells, macrophages, atypical lymphoid cells and eosinophils. Radiotherapy was very effective and led to long-term remission. The different etiological aspects of this syndrome are discussed.

Abstract
In this study a flow cytometric technique for detecting cytoplasmic perforin (P) has been used to quantify age-related changes in perforin expression in human peripheral blood lymphocytes (PBL). Proportions of P+ lymphocytes increased after birth, but declined rapidly after the age of 70 years. This was true for both T cells and CD16(+) and CD56(+) natural killer (NK) cells. Children showed in addition to high levels of perforin positive CD8(+) cells a much higher proportion of CD4(+)P+ cells than the other age groups. In elderly individuals there was also a highly significant reduction in mean levels of perforin per cell as compared with all other groups (P < .05 to .001). Adult women had consistently higher mean levels of perforin per cell than adult men for all P+ cell phenotypes. Functional tests clearly showed the deficiency in early spontaneous cytotoxic potential of PBL from elderly persons due to relative P deficiency, which can be corrected by stimulation of cytolytic cells with target cells and interleukin-2 (IL-2). The deficiency in cytolytic activity on the contact with target cells may have implications for antiviral and antitumor immunity in elderly persons.
