Dreaming under anesthesia: is it a real possiblity? Investigation of the effect of preoperative imagination on the quality of postoperative dream recalls.

BACKGROUND: Images evoked immediately before the induction of anesthesia by means of suggestions may influence dreaming during anesthesia. This study is a retrospective re-evaluation of the original prospective randomized trial. METHODS: Dream reports were studied in two groups. In group 1. dreams of patients who received suggestions, and in group 2, those of the control group of patients who did not. The incidence of dream reports and the characteristics and the theme of the reported dreams were compared among the groups. RESULTS: In general, the control and the psychological intervention groups were different in terms of dreaming frequency, and non-recall dreaming. The incidence of dream reports was significantly higher in the suggestion group (82/190 at 10 min and 71/190 at 60 min respectively) than in the control group (16/80 at 10 min and 13/80 at 60 min, respectively; p10 = 0.001 and p60 = 0.002). There were no differences in the nature (thought- like or cinematic), quality (color or B&W) and the mood (positive vs. negative) of the recalled dreams. In general, the contents of the imaginary favorite place and the reported dream were identical in 73.2 %. Among the topics most successfully applied in the operating theater were loved ones (83.8 %), holiday (77.8 %) and sport (63.6 %). CONCLUSION: The results of the present study suggest that dreams during anesthesia are influenced by suggestions administered immediately preceding anesthesia. TRIAL REGISTRATION: The study was registered in ClinicalTrials.gov. Identifier: Q1 NCT01839201 , Date: 12 Apr. 2013.

The effect of preoperative suggestions on perioperative dreams and dream recalls after administration of different general anesthetic combinations: a randomized trial in maxillofacial surgery.

BACKGROUND: Images evoked immediately before the induction of anesthesia with the help of suggestions may influence dreaming during anesthesia.The aim of the study was to assess the incidence of evoked dreams and dream recalls by employing suggestions before induction of anesthesia while administering different general anesthetic combinations. METHODS: This is a single center, prospective randomized including 270 adult patients scheduled for maxillofacial surgical interventions. Patients were assigned to control, suggestion and dreamfilm groups according to the psychological method used. According to the anesthetic protocol there were also three subgroups: etomidate & sevoflurane, propofol & sevoflurane, propofol & propofol groups. Primary outcome measure was the incidence of postoperative dreams in the non-intervention group and in the three groups receiving different psychological interventions. Secondary endpoint was to test the effect of perioperative suggestions and dreamfilm-formation training on the occurrance of dreams and recallable dreams in different general anesthesiological techniques. RESULTS: Dream incidence rates measured in the control group did not differ significantly (etomidate & sevoflurane: 40%, propofol & sevoflurane: 26%, propofol & propofol: 39%). A significant increase could be observed in the incidence rate of dreams between the control and suggestion groups in the propofol & sevoflurane (26%-52%) group (p = 0.023). There was a significant difference in the incidence of dreams between the control and dreamfilm subgroup in the propofol & sevoflurane (26% vs. 57%), and in the propofol & propofol group (39% vs.70%) (p = 0.010, and p = 0.009, respectively). Similar to this, there was a significant difference in dream incidence between the dreamfilm and the suggestion subgroups (44% vs. 70%) in the propofol & propofol group (p = 0.019). Propofol as an induction agent contributed most to dream formation and recalls (χ2-test p value: 0.005). The content of images and dreams evoked using suggestions showed great agreement using all three anesthetic protocols. CONCLUSION: The psychological method influenced dreaming during anesthesia. The increase of the incidence rate of dreams was dependent on the anesthetic agent used, especially the induction agent. The study was registered in ClinicalTrials.gov. Identifier: NCT01839201.

[Branchiogen cyst at unusual age and in rare localization. A case report]. / oBranchiogén ciszta elofordulása szokatlan életkorban, ritka lokalizációban. Esetismertetés.

Branchiogen anomalies represent a heterogeneous group of developmental abnormalities, they arise from incomplete obliteration of branchial clefts and pouches during embriogenesis. Clinically they can present as a cyst, fistula or sinus. Second cleft lesions account for 95% of the branchial anomalies. Second branchial cleft cysts are usually located in the neck, along the anterior border of the stenocleidomastoid muscle, but they can be anywhere along the course of the second branchial fistula from the tonsillar fossa to the supraclavicular region. Their presence in the nasopharynx is extremely rare. Ultrasound, computed tomography (CT) or magnetic resonance imaging is recommended for diagnosis. Definitive treatment is surgical excision, these lesions do not regress spontaneously and often result recurrent infections. A 7 month old infant applied to a pediatrician with gastrointestinal viral infection. During examination a cystic mass was discovered in the right lateral nasopharyngeal wall, the lesion extended to the oropharynx. Marsupialisation was performed via transoral approach. In case of cystic lesion in the lateral epipharynx, branchial cleft cyst should be considered in the differential diagnosis.

Frequency of genetic and epigenetic alterations of p14ARF and p16INK4A in head and neck cancer in a Hungarian population.

Occurrence of genetic and epigenetic alterations affecting p14ARF and p16INK4A were investigated in tumour samples of 37 oral (OSCC) and 28 laryngeal squamous cell cancer (LSCC) patients, and compared to exfoliated buccal epithelial cells of 68 healthy controls. Presence of deletions and mutations/polymorphisms affecting exons were examined using sequencing. Methylation status of promoters was assessed by methylation-specific PCR. Chi-square and Fisher's exact tests were used to compare frequency of events. Exon deletions were found in four controls, one OSCC and 22 LSCC patients; the latter significantly differed from controls (p < 0.001). Only two mutations (T24610A and C24702A) were in p16 exon 1 of two OSCC patients. Polymorphisms G28575A (Ala140Thr), G31292C (C540G) and G28608A were found in both patient groups. The p14 promoter was unmethylated in 86.7 % of OSCC and in 85.7 % of LSCC patients; for the p16 promoter these rates were 69.0 % and 76.2 % for OSCC and LSCC patients, respectively. Combining the two patient groups, unmethylated promoter was significantly less frequent in case of both p14 and p16 (p = 0.043 and p = 0.001, respectively) compared to the control group. In summary, exon deletion may be important in LSCC, while promoter methylation was relatively frequent in both patient groups.

[Osteonecrosis of the jaw developing during bisphosphonate treatment]. / Biszfoszfonát-kezelés során fellépo állcsontnecrosis.

The article discusses osteonecrosis of the jaw as a possible side effect of bisphosphonate treatment. It provides practical guidelines for prevention, diagnosis and management of bisphosphonate-associated osteonecrosis according to literature and clinical evidence. Since controlled clinical trials have not been carried out, the recommendations are based on reviews, reports and clinical experience. Osteonecrosis of the jaw (ONJ) is a historical clinical entity, which can potentially develop in cancer patients receiving bisphosphonate therapy. The pathogenesis of ONJ has not been totally revealed yet. A thorough dental/oral surgical examination and counseling is recommended in cases when intravenous bisphosphonate therapy is needed. All required dental and surgical treatment should be carried out before starting bisphosphonate therapy to prevent ONJ. The patient should be informed about the possible side effects, and the importance of good oral home care and regular dental check-ups. Once the intravenous bisphosphonate therapy has started, only conservative manipulations should be carried out in the oral cavity. Even in case of developed ONJ, suspension of bisphosphonate therapy is not necessary. In these cases a non-surgical approach is recommended concerning the treatment of ONJ. Regarding the growing number of ONJ cases in association with bisphosphonate therapy it is important for the professionals treating cancer patients to be aware of this phenomenon and the importance of prevention.

Oral cancer report from Northeastern Hungary.

In Hungary oral and pharyngeal cancers have been reported the fourth most common malignancy in males and the sixth for both sexes. The aim of the present study was to characterize oral squamous cell carcinoma (OSCC) patients in Northeastern Hungary. 119 randomly selected patients with OSCC were included in the study. Epidemiological data, clinicopathological parameters and the risk factors were registered. The most common sites of OSCC were the floor of the mouth (27.7%), the lip (26.9%) and the tongue (22.7%). The majority of the patients was diagnosed with early stage (I-II) lesions and moderately differentiated tumors. The 5-year overall survival rate was 38.7%. There was a significant correlation between survival and tumor size, lymph node involvement and clinical stage. At the time of diagnosis 65.5% of the patients were smokers. Smoking significantly correlated with younger age, male gender, advanced clinical stages and alcohol consumption. 75.5% of the patients consumed alcohol, 41.1% of them exceeding the conventional amount regularly. Drinking habit significantly correlated with younger age, male gender and tumor site i.e. gingiva, retromolar region, tongue. The dental status was acceptable only in 12.6% of the cases. There was a significant correlation between dental status and age, smoking and drinking habits. Clinical stage has the most significant impact on survival and the most important high-risk habits in Northeastern Hungary are smoking and alcohol consumption. Therefore, early detection and treatment, cessation of tobacco and alcohol abuse, and a regular dental care may improve patients' survival in the region.

[Oral squamous cell carcinoma in north-eastern Hungary. II. Etiological factors]. / Szájüregi laphámrákok az eszakkelet-magyarországi régióban. II. Etiológiai faktorok.

The purpose of this study is to determine the possible etiological factors of oral squamous cell carcinoma (OSCC) in North-Eastern Hungary. The medical records of 119 randomly selected patients with OSCC admitted to the Department of Maxillofacial Surgery of the Faculty of Dentistry, University of Debrecen were reviewed. The following risk factors were investigated: tobacco and alcohol consumption, dental status, rural vs. urban residence, and high risk HPV infection. The presence of HPV DNA has been evaluated by polymerase chain reaction from the tissue samples. Results were correlated with clinical data. At the time of diagnosis 65.5 percent of the patients were smokers. Under the age of 45 the rate was 86.4%. Smoking significantly correlated with younger age, male gender, advanced clinical stages and alcohol consumption. The majority of the patients (75.5%) consumed alcohol, 41.1% regularly over the acceptable range. Drinking habit significantly correlated with younger age, male gender and tumor site (gingiva, retromolar region, tongue). HR-HPV types were detected in 42.8% of samples tested. HPV DNA presence was not related to gender, clinical stage, histological grade or other risk factors. Authors found weak correlation between HR-HPV positivity, younger patient age and better 5-year survival rate. The dental status was acceptable only in 12.6 percent of the cases. There was a correlation between dental status and age, smoking and drinking habits. No significant urban-rural differences were found. In the study population the most important risk factor for developing oral cancer is tobacco smoking followed by alcohol consumption. Avoidance of tobacco smoking and a reduced amount of alcohol, together with healthy nutrition and regular dental care should be emphasized.

[Oral squamous sell carcinoma in North-Eastern Hungary I. Epidemiology]. / Száüregi laphámrákok az északkelet-magyarországi régióban I.

The purpose of this study was to characterize the epidemiological data of oral squamous cell carcinoma (OSCC) patients in North-Eastern Hungary. The medical records of 119 randomly selected patients with OSCC admitted to the Department of Maxillofacial Surgery of the Faculty of Dentistry, University of Debrecen were reviewed. Cases were identified according to the epidemiological data, as to site, tumor size, lymph node involvement, clinical stage, histological differentiation, treatment obtained, recurrence of disease and survival rate. There was an obvious male predominance (male:female = 5.2:1). The median age at diagnosis was 57.4 years. The most common sites of OSCC were the floor of the mouth (27.7%), the lip (26.9%) and the tongue (22.7%). The majority of the patients (58,8%) presented with early-stage (I-II) disease at the time of diagnosis, and 48.6% had moderately differentiated tumors. The most frequent therapeutic modality used was surgery with or with out of radiotherapy. Roughly one fifth of the cases (20.7%) experienced a recurrence of disease during the follow-up period. The overall 5-year survival rate was 38.7% (stage I: 68.3%, stage II: 31.0%, stage III: 22.6%, stage IV: 11.1%). There was a correlation between survival and tumor size, lymph node metastasis, clinical stage and surgical treatment (p < or = 0.05, respectively). We found no significant correlation between histological differentiation and survival. Clinical stage exerts the most strongly significant impact on survival. Therefore, early detection and proper surgical intervention enhance patients' survival most effectively.

Rare, late complications in a patient with Hodgkin's disease.

We report a unique case of a cured Hodgkin's disease patient who developed several complications decades after mantle and neck radiation therapy. First on the right, then years later on the left side of the neck a pharyngocutaneous fistula developed complicated by rupture of the carotid arteries on both sides necessitating their ligation. The fistula on the right side was successfully closed by plastic surgery, but the one on the left side is still a problem as severe hypoperfusion of the brain limits therapeutic possibilities. We discuss the relationships between the treatment for Hodgkin's disease and subsequent complications as well as treatment of these complications.
