  • Hearing loss in vitiligo: current concepts and review
    • Authors: Marrigje Aagje de Jong; Cahtia Adelman; Menachem Gross
      Pages: 2367 - 2372
      Abstract: Abstract The objective of this study was to describe the occurrence, clinical manifestations, audiometric findings, pathogenesis and approach to sensorineural hearing loss (SNHL) among patients diagnosed with vitiligo with a review of the literature. We present a systematic review of the literature on cases of SNHL in patients diagnosed with vitiligo and studies conducted to investigate audiometric changes in such patients. Data on presentation, diagnosis and medical approach were reviewed. A total of 21 studies and case reports revealed at least 102 cases of SNHL in patients diagnosed with vitiligo. Arguments for a common causative etiology related to melanocyte function were mentioned in most of the literature. Evaluation of hearing function among all patients diagnosed with vitiligo seems to be an accepted approach; it should include audiometry, otoacoustic emissions (OAE) and ABR measurements. Extra precaution to prevent ototoxic or noise-induced hearing loss is strongly recommended. Further research is needed to better understand its pathogenesis.

  • MicroRNAs: effective elements in ear-related diseases and hearing loss
    • Authors: Mohammad-Reza Mahmoudian-sani; Ameneh Mehri-Ghahfarrokhi; Fereshteh Ahmadinejad; Morteza Hashemzadeh-Chaleshtori; Massoud Saidijam; Mohammad-Saeid Jami

      Abstract: Abstract miRNAs are important factors for post-transcriptional process that controls gene expression at mRNA level. Various biological processes, including growth and differentiation, are regulated by miRNAs. miRNAs have been demonstrated to play an essential role in development and progression of hearing loss. Nowadays, miRNAs are known as critical factors involved in different physiological, biological, and pathological processes, such as gene expression, progressive sensorineural hearing loss, age-related hearing loss, noise-induced hearing loss, cholesteatoma, schwannomas, and inner ear inflammation. The miR-183 family (miR-183, miR-96 and miR-182) is expressed abundantly in some types of sensory cells in inner ear specially mechanosensory hair cells that exhibit a great expression level of this family. The plasma levels of miR-24-3p, miR-16-5p, miR-185-5p, and miR-451a were upregulated during noise exposures, and increased levels of miR-21 have been found in vestibular schwannomas and human cholesteatoma. In addition, upregulation of pro-apoptotic miRNAs and downregulation of miRNAs which promote differentiation and proliferation in age-related degeneration of the organ of Corti may potentially serve as a helpful biomarker for the early detection of age-related hearing loss. This knowledge represents miRNAs as promising diagnostic and therapeutic tools in the near future.

  • Laser Eustachian Tuboplasty for Eustachian Tube Dysfunction: a case series
           review
    • Authors: Benjamin John Miller; Mustafa Jaafar; Hassan A. Elhassan
      Pages: 2381 - 2387
      Abstract: Abstract The authors reviewed the literature regarding the safety and efficacy of Laser Eustachian Tuboplasty (LETP) in the treatment of Eustachian tube dysfunction (ETD). Medline via Pubmed, OvidSP and Science Direct were consulted, with a supplementary manual review of citations. English language case series constituted a baseline for inclusion. Primary outcome measures were pre- and post-operative tympanometry, otoscopy findings, subjective symptoms and pure tone audiometry, and findings were stratified into short term (≤6 months) and long term (>6 months–5 years). Eight unique case series were identified, detailing LETP procedures in 306 patients (462 Eustachian tubes). LETP demonstrated mixed short-term and positive long-term results across primary outcome measures. There was an overall complication rate of ≈4.4%, and no major adverse events were reported. Poor documentation of pre- and post-operative primary outcome measures and inter-study outcome heterogeneity prevents substantive comment on efficacy. Whilst LETP is safe, its use should remain limited to research in adults. Future trials should be case controlled, and detail pre- and post-operative tympanometry, otoscopy findings, subjective symptoms, and pure tone audiometry. Patients should also be stratified into those suffering from baro-challenge induced ETD, and those suffering from ETD with intractable sequelae, such as Chronic Otitis Media.

  • The controversial role of electrochemotherapy in head and neck cancer: a
           systematic review of the literature
    • Authors: Riccardo Lenzi; Luca Muscatello; Alberto Maria Saibene; Giovanni Felisati; Carlotta Pipolo
      Pages: 2389 - 2394
      Abstract: Abstract Electroporation, also known as electrochemotherapy, combines an antineoplastic agent with electroporation, causing localized progressive necrosis in the treated area. Today it is primarily used in the palliative treatment of cutaneous and subcutaneous metastases and has been found to be safe and efficacious in head and neck cancer recurrences. Despite the steady increase in the number of published studies this treatment is not universally available and used systematically in head and neck carcinomas. To shed light on its limitations and analyze treatment outcome we have, therefore, reviewed all available literature regarding this topic. This systematic review includes 16 studies on head and neck squamous cell carcinoma and reports the data of 200 treated patients. The combined results show a very heterogeneous overall response rate, ranging from 0 to 100%, while the complete response rate ranges between 0 and 83.3%. No major side effects have been described in those who used electrochemotherapy as a mono modality palliative treatment. This systematic review shows how standardization of treatment is still pivotal to achieve a more homogeneous response rate in the approach to head and neck tumors. In conclusion, due to the scarcity of alternatives of treatment in advanced stage cancer in this anatomical region and the good tolerability and mostly high success rates of electrochemotherapy, this palliative approach should be taken into consideration in these patients.

  • Balloon Eustachian Tuboplasty in children
    • Authors: A. Leichtle; D. Hollfelder; B. Wollenberg; K.-L. Bruchhage
      Pages: 2411 - 2419
      Abstract: Abstract Endonasal ballon dilatation of the Eustachian tube (BET) is a promising treatment for Eustachian tube dysfunction with encouraging results over the last years in adults. In addition, in children, single studies demonstrated promising results, but revealed the necessity for broader and additional studies. Our retrospective analysis presents outcomes with BET in children with chronic obstructive dysfunction of the Eustachian tube, showing resistance to the conventional therapy after adenotomy with paracentesis or grommets (ventilation tubes). The data of 52 children, having undergone BET from April 2011 to April 2016, were retrospectively evaluated. Most children in our study presented middle ear effusion (47%), adhesive (21%), chronic otitis media (13%), or recurrent acute otitis media (11%). In 24 (37%) children, we combined BET with a paracentesis, in 5 (8%) patients with a tympanoplasty type I and in 3 (5%) patients with a type III. All children were assessed using an audiogram, tympanometry, and tubomanometry (50 mbar) before and after BET. In addition, we evaluated the results of the Lübecker questionnaire, which we performed before and after BET. The childrens’ ear-related and quality of life-related symptoms, such as pressure equalization, ear pressure, hearing loss, pain and limitation in daily life, and satisfaction pre- and postoperatively, were analyzed. In the majority of patients, we could see an improvement in the ear pressure, hearing loss, limitation in daily life, and satisfaction with recurrent inflammations, underlined by better outcomes in the tubomanometry and the tympanogram. BET in children is a safe, efficient, and promising method to treat chronic tube dysfunction, especially as a second line treatment, when adenotomy, paracentesis, or grommets failed before.

  • Baha implant as a hearing solution for single-sided deafness after
           retrosigmoid approach for the vestibular schwannoma: surgical results
    • Authors: Jan Boucek; Jan Vokral; Libor Cerny; Martin Chovanec; Jiří Skrivan; Eduard Zverina; Jan Betka; Michal Zabrodsky
      Pages: 2429 - 2436
      Abstract: Abstract Skull base tumors and, in particular, vestibular schwannoma (VS) are among the etiological reasons for single-sided deafness (SSD). Patients with SSD have problems in understanding speech in a noisy environment and cannot localize the direction of sounds. Baha is one of the most frequently used systems for SSD compensation. Out of 38 patients with SSD after retrosigmoid removal of VS who underwent testing with Baha softband, 16 were satisfied and were indicated for Baha implantation. Two surgical approaches have been used—the Nijmegen linear incision technique with subdermal thinning (Group I, implant BI300) and fast surgery technique without subdermal thinning (Group II, implant BIA400). The duration of the surgery, the implant stability measured by Ostell, and skin or soft tissue reactions in long range follow-up were evaluated and compared between Group I and II. There was a difference in duration of surgery, in Group II procedures averaged significantly faster (p > 0.001). In both groups, there was a similar trend of the gradual increase of implant stability. In the Group I and II, there was comparable rate of the skin or soft tissue reactions grade 0, I, II, or III. We have proved Baha to be a suitable possibility for SSD patients after the removal of VS, regardless of the approach. After the retrosigmoid approach to the VS, the key step of Baha implantation must be to reach intact healthy bone to avoid implantation into scar tissue.

      Abstract: Abstract The aim of this study was to examine the efficacy of methylprednisolone in vestibular neuritis (VN) by objective and subjective measures. This prospective controlled randomized study was conducted at one tertiary hospital. Twenty-nine VN patients were randomized to either the steroid (n = 15) or the control (n = 14) group. The steroid group received methylprednisolone for 2 weeks, whereas control patients did not; both groups underwent regular vestibular exercises and were prescribed a Ginkgo biloba. Vestibular function tests including caloric test, video head impulse test (vHIT), and sensory organization test (SOT) were performed, and dizziness handicap index (DHI) was determined at enrollment; all tests were repeated at 1 and 6 months after enrollment. Both groups showed statistically significant improvements in caloric weakness and vHIT gain at 1- and 6-month follow-up evaluations compared to the initial examination; however, differences were not significant. The rates of normalization of canal paresis at 1 and 6 months were 50 and 64% in the control group and 33 and 60% in the steroid group, respectively, with no differences between the two groups. The rates of vHIT normalization at 1 and 6 months after treatment were 57 and 78% in the control group and 53 and 87% in the steroid group, respectively, with no differences between the two groups. Finally, there were no significant differences in the improvement of composite scores of SOT and the DHI scores between the two groups. In this prospective RCT, methylprednisolone had no additional benefit in patients with VN who underwent vestibular exercises and received a Ginkgo biloba.

      Abstract: Abstract To detect ultra-structural changes of Rabbit’s olfactory neuro-epithelium using scanning electron microscope after exposure to cigarette smoking. Sixty six rabbits (Pathogen free New Zealand white rabbits weighing 1–1.5 kg included in the study were randomly assigned into one of three groups: control group did not expose to cigarette smoking, study group 1 was exposed to cigarette smoking for 3 months and study group 2 was exposed to cigarette smoking 3 months and then stopped for 2 months. Olfactory neuro-epithelium from all rabbits were dissected and examined under Philips XL-30 scanning electron microscope. Changes that were found in the rabbits of study group 1 in comparison to control group were loss of microvilli of sustentacular cells (p = 0.016) and decreases in distribution of specialized cilia of olfactory receptor cells (p = 0.046). Also respiratory metaplasia was detected. These changes were reversible in study group 2. Cigarette smoking causes ultra-structural changes in olfactory neuro-epithelium which may explain why smell was affected in cigarette smokers. Most of these changes were reversible after 45 days of cessation of cigarette smoking to the rabbits.

  • A comparison of piezosurgery with conventional techniques for internal
           osteotomy
    • Authors: İ. Koçak; R. Doğan; O. Gökler
      Pages: 2483 - 2491
      Abstract: Abstract To compare conventional osteotomy with the piezosurgery medical device, in terms of postoperative edema, ecchymosis, pain, operation time, and mucosal integrity, in rhinoplasty patients. In this prospective study, 49 rhinoplasty patients were randomly divided into two groups according to osteotomy technique used, either conventional osteotomy or piezosurgery. For all patients, the total duration of the operation was recorded, and photographs were taken and scored for ecchymosis and edema on postoperative days 2, 4, and 7. In addition, pain level was evaluated on postoperative day 2, and mucosal integrity was assessed on day 4. All scoring and evaluation was conducted by a physician who was blinded to the osteotomy procedure. In the piezosurgery group, edema scores on postoperative day 2 and ecchymosis scores on postoperative days 2, 4, and 7 were significantly lower than in the conventional osteotomy group (p < 0.05). On postoperative day 2, the pain level was lower in the piezosurgery group than in the conventional osteotomy group (p < 0.05). In an endoscopic examination on postoperative day 4, while 24% of the patients in the conventional osteotomy group had mucosal damage, no such damage was observed in the piezosurgery group. When total operation duration was compared, there was no significant difference between the groups (p > 0.05). Piezosurgery is a safe osteotomy method, with less edema (in the early postoperative period) and ecchymosis compared with conventional osteotomy, as well as less pain, a similar operation duration, and no mucosal damage.

  • Surgical and pathogenetic considerations of frontal sinus fungus ball
    • Authors: Elena Bernardini; Apostolos Karligkiotis; Susanna Fortunato; Paolo Castelnuovo; Iacopo Dallan
      Pages: 2493 - 2497
      Abstract: Abstract Fungus ball (FB) is an non-invasive form of mycosis, that generally affects immunocompetent and non-atopic subjects. Involvement of the frontal sinus is extremely rare. We report two cases with frontal sinus fungus ball that underwent endoscopic endonasal frontal Draf type IIb or III sinusotomy with complete removal of the cheesy clay-like material. There were no intra-operative or postoperative complications, and no recurrence of disease was evident during the follow-up of 51 and 26 months, respectively. The Draf type IIb or type III frontal sinusotomy seems to be highly effective for the treatment of frontal sinus FB and can represent a valid alternative to the traditional external approaches.

  • Circulating calprotectin as a biomarker of laryngeal carcinoma
    • Authors: Muhammet Fatih Topuz; Adem Binnetoglu; Ali Cemal Yumusakhuylu; Murat Sarı; Tekin Baglam; Fetullah Gerin
      Pages: 2499 - 2504
      Abstract: Abstract Calprotectin is an S100 protein and marker of inflammation found in neutrophils and monocytes; S100 proteins are a family of calcium-modulated proteins. The aim of this study was to determine if the serum concentration of calprotectin is higher in patients with laryngeal carcinoma than in patients with benign laryngeal pathologies and controls. The study included 107 participants. The serum calprotectin concentration was analyzed using the calprotectin ELISA (enzyme-linked immunosorbent assay) kit (Calpo AS, Norway). EDTA-serum for analysis was collected prior to surgery from patients with laryngeal carcinoma (n = 41), those with a benign laryngeal pathology (Reinke’s edema, vocal nodules, etc.) (n = 32), and healthy controls (n = 34). The median serum calprotectin concentration was significantly higher in the laryngeal carcinoma group (2179.6 μg L−1) than in the benign laryngeal pathology group (727.84 μg L−1) and control group (733.73 μg L−1) (P < 0.05). The median serum calprotectin concentration in patients with advanced-stage laryngeal cancer (5854.,4 μg L−1) was significantly higher than in those with early-stage laryngeal cancer (971.84 μg L−1) (P < 0.05); however, there was not a significant difference in the median calprotectin concentration between the control and benign laryngeal pathology groups (P > 0.05). Furthermore, the median serum calprotectin concentration in the patients with early-stage laryngeal cancer (n = 21) (971.84 μg L−1) was significantly higher than that in the benign laryngeal pathology and control groups (n = 64) (730.6 μg L−1) (P < 0.05). The serum calprotectin concentration was strongly correlated with poor survival and advanced-stage laryngeal carcinoma. Malignant laryngeal cancer patients (n = 4) that died during follow-up had a higher median serum calprotectin concentration (9468.4 μg L−1) than those that remained alive (n = 37) (857.78 μg L−1) (P < 0.05). The serum calprotectin concentration is higher in patients with laryngeal carcinoma than in those with benign laryngeal pathologies and healthy controls. The present findings show that the serum calprotectin concentration might be used as a marker to discriminate between laryngeal carcinoma and benign laryngeal pathologies. Additional research is needed to further assess the value of this parameter as a useful tumor marker for the diagnosis, treatment, and follow-up of laryngeal carcinoma.

  • Erythropoietin levels in patients with sleep apnea: a meta-analysis
    • Authors: Xiao-Bin Zhang; Yi-Ming Zeng; Hui-Qing Zeng; Hua-Ping Zhang; Hui-Ling Wang
      Pages: 2505 - 2512
      Abstract: Abstract Currently available data regarding the blood levels of erythropoietin (EPO) in sleep apnea (SA) patients are contradictory. The aim of the present meta-analysis was to evaluate the EPO levels in SA patients via quantitative analysis. A systematic search of Pubmed, Embase, and Web of Science were performed. EPO levels in SA group and control group were extracted from each eligible study. Weight mean difference (WMD) or Standard mean difference (SMD) with 95% confidence interval (CI) was calculated by using fixed-effects or random effect model analysis according to the degree of heterogeneity between studies. A total of 9 studies involving 407 participants were enrolled. The results indicated that EPO levels in SA group were significantly higher than that in control group (SMD 0.61, 95% CI 0.11–1.11, p = 0.016). Significantly higher EPO levels were found in patients with body mass index <30 kg/m2, and cardiovascular complications in the subsequent subgroup analysis (both p < 0.05). High blood EPO levels were found in SA patients in the present meta-analysis.

  • A retrospective study of ultrasound and FNA cytology investigation of
           thyroid nodules: working towards combined risk stratification
    • Authors: Zi Wei Liu; Richard Fox; Samit Unadkat; Roy Farrell
      Pages: 2537 - 2540
      Abstract: Abstract The British Thyroid Association recommended in new guidelines on thyroid cancer treatment [Kwak et al. (Korean J Radiol 14:110–117, 2013)] that ultrasound grading of thyroid nodules should be incorporated into MDT management. A retrospective study was carried out to determine that the impact of US grading has had on MDT decision making in practice. The design used in the study is a retrospective review of case notes. The study was carried out in the hub hospital for thyroid cancer in the North west London Cancer network. We included consecutive patients referred to the regional thyroid multidisciplinary meeting between August 2014 and May 2015 for investigation of thyroid nodules. Data were collected on patient demographics, co-morbidity, thy grading, ultrasound grading, surgery, post-operative histology, and radioactive iodine treatment details. Accuracy of cytology and ultrasound in diagnosing malignancy was correlated to definitive histology. 99 patients with thyroid nodules were included in the study. 97% of patients had at least one fine needle aspiration and 75% had ultrasound grading. Thy3f (Bethesda IV) nodules were more likely to be carcinoma if associated with a U4 grade rather than U3 (67 vs 18%, p = 0.028). Ultrasound grading has recently been introduced to the standard practice in investigation of thyroid nodules. Further assessment of the accuracy of ultrasound grading in clinical practice may allow us to risk-stratify thy3a/thy3f (Bethesda III/IV) lesions and personalise treatment.

  • Nonanaplastic follicular cell-derived thyroid carcinoma: mitosis and
           necrosis in long-term follow-up
    • Authors: Daniel Bräuner Skansing; Stefano Christian Londero; Pia Asschenfeldt; Stine Rosenkilde Larsen; Christian Godballe
      Pages: 2541 - 2548
      Abstract: Abstract Nonanaplastic follicular cell-derived thyroid carcinoma (NAFCTC) includes differentiated- (DTC) and poorly differentiated thyroid carcinoma (PDTC). DTC has an excellent prognosis, while PDTC is situated between DTC and anaplastic carcinomas. Short-term studies suggest that PDTC patients diagnosed only on tumor necrosis and/or mitosis have a prognosis similar to those diagnosed according to the TURIN proposal. The purpose of this study was to evaluate prognosis for NAFCTC based on long-term follow-up illuminating the significance of tumor necrosis and mitosis. A cohort of 225 patients with NAFCTC was followed more than 20 years. Age, sex, distant metastasis, histology, tumor size, extrathyroidal invasion, lymph node metastasis, tumor necrosis and mitosis were examined as possible prognostic factors. Median follow-up time for patients alive was 28 years (range 20–43 years). Age, distant metastasis, extrathyroidal invasion, tumor size, tumor necrosis and mitosis were independent prognostic factors in multivariate analysis for overall survival (OS). In disease specific survival (DSS) age was not significant. Using only necrosis and/or mitosis as criteria for PDTC the 5-, 10- and 20-year OS for DTC was 87, 79 and 69%, respectively. In DSS it was 95, 92 and 90%. For PDTC the 5-, 10- and 20-year OS was 57, 40 and 25%, respectively. In DSS it was 71, 55 and 48%. Tumor necrosis and mitosis are highly significant prognostic indicators in analysis of long time survival of nonanaplastic follicular cell-derived thyroid carcinoma indicating that a simplification of the actually used criteria for poorly differentiated carcinomas may be justified.

      Abstract: Abstract This study aimed to evaluate and compare the immunoexpression of glucose transporter-1 (GLUT-1) and angiogenic index between pleomorphic adenomas (PAs), adenoid cystic carcinomas (ACCs), and mucoepidermoid carcinomas (MECs) of the salivary glands, and establish associations with the respective subtype/histological grade. Twenty PAs, 20 ACCs, and 10 MECs were submitted to morphological and immunohistochemical analysis. GLUT-1 expression was semi-quantitatively evaluated and angiogenic index was assessed by microvessel counts using anti-CD34 antibody. Higher GLUT-1 immunoexpression was observed in the MECs compared to PAs and ACCs (p = 0.022). Mean number of microvessels was 66.5 in MECs, 40.4 in PAs, and 21.2 in ACCs (p < 0.001). GLUT-1 expression and angiogenic index showed no significant correlation in the tumors studied. Results suggest that differences in biological behavior of the studied tumors are related to GLUT-1. Benign and malignant salivary gland tumors differ in the angiogenic index; however, angiogenesis may be independent of the tumor cell’s metabolic demand.

      Abstract: Abstract The treatment of patients with cervical lymph node metastases without detectable primary tumor remains an important challenge, until today, no standard therapy is available. The present study investigated the multimodal treatment of patients with head and neck CUP syndrome (HNCUP) and their follow-up retrospectively. 81 patients with cervical lymph node metastases without a primary tumor were treated at the Departments of Otorhinolaryngology as well as Radiotherapy and Radiation Oncology at the University of Saarland in Homburg, Germany in the period between 1991 and 2013. All patients received routine work-up consisting of CUP panendoscopy and imaging. Neck dissection was then performed in 77% of the patients. The most common histology was squamous cell carcinoma (80%). Ten percent of the patients had distant metastases. All patients underwent primary or adjuvant radiation therapy, or simultaneous radiochemotherapy. After a median follow-up of 3.5 years, the 5-year survival rate was 30%. There was a local recurrence that was known in 20/63 patients (31%) and distant metastases were documented in 19/61 M0 patients (31%). Higher grade late toxicity (grade 3–4) was observed in 12% of patients. Neck dissection and radiation therapy remains an integral part of HNCUP therapy, while the use of chemotherapy could be considered in selected cases. Prospective multicenter randomized trials would be necessary to identify the best target volume and to clarify the role of chemotherapy.

  • Polymorphism 4G/5G of the plasminogen activator inhibitor 1 gene as a risk
           factor for the development of allergic rhinitis symptoms in patients with
           asthma

      Abstract: Abstract Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein which has a role in tissue remodelling after inflammatory processes. The objective is to investigate the frequency of PAI-1 gene polymorphism (4G/5G) in patients with a lung ventilation dysfunction in asthma and allergic rhinitis. Genomic DNA was isolated and genotypes of polymorphism of PAI-1 4G/5G and ABO were determined using the methods of RT-PCR and PCR-SSP. Study group includes 145 adult patients diagnosed with chronic asthma, with all clinically relevant parameters and the laboratory markers of pO2, IgE and eosinophils in sputum and nasal swab. In the processing of data, appropriate statistical tests (Kolmogorov–Smirnov test, median, interquartile ranges, χ 2 and Mann–Whitney U tests) were used. Patients with symptoms of allergic rhinitis were significantly younger and had an almost four time higher levels of IgE (P = 0.001), higher pO2 (P = 0.002) and PEF (P = 0.036), compared to those who do not have these symptoms. Genotype PAI 4G/4G is significantly more common in patients with allergic rhinitis (28.1% vs. 16.1%; P = 0.017) compared to the genotype 5G/5G. Carriers of the genotype 4G/5G also have a borderline statistical significance. There were no statistically significant difference in the incidence of allergic rhinitis in the carriers of any ABO genotypes. The frequency of PAI genotype 4G/4G is significantly more common in patients with allergic rhinitis. The results suggest that the carriers of at least one 4G allele are at a higher risk for developing symptoms of allergic rhinitis in asthma.

Since other functional neuroimaging technique findings are lacking in the literature, present study used a validated 18F-2-fluoro-2-deoxy-d-glucose (FDG) functional positron emission tomography procedure under olfactory stimulation (OS) to assess brain changes in idiopathic anosmic patients (IAPs) in comparison with healthy subjects (HS). A voxel-based analysis between these groups was used to evaluate FDG uptake in the brain and perform a correlation analysis between metabolic responses and the Sniffin’ stick test as well as intensity visuo-analogue scores and disease duration (DD). A significant relative decrease of glucose metabolism in the right and left frontal lobes, left insula, right parietal lobe, and left occipital, temporal and parietal lobes was found in IAPs during OS. The same condition resulted in a relative higher glucose metabolism in the right cerebellum in IAPs. Moreover, a negative correlation between DD and FDG uptake in the left temporo-parietal joint was found in IAPs. Such a correlation suggested a possible involvement of this area metabolic decrease in self-consciousness impairment, which is known to affect IAPs. Present preliminary functional results could be of interest to further deepen such neural impairments possibly useful for future perspective in pharmaceutical and rehabilitative protocols.
