RESUMO

Nasal obstruction is common in patients with a transverse maxillary deficiency. The aim of this study was to determine the variation in nasal airway resistance in adult patients with a transverse maxillary deficiency before and after surgically assisted rapid maxillary expansion (SARME) by computational fluid dynamics (CFD) using computed tomography scans, and to correlate this variation with maxillary linear measurements obtained by means of plaster models. The subjective symptoms of nasal obstruction were also analysed using a visual analogue scale (VAS) for nasal breathing and the Nasal Obstruction Symptom Evaluation (NOSE) scale. There was a median reduction of 21% in nasal airway resistance post SARME (P = 0.002). The NOSE scale score decreased (P < 0.001) and nasal breathing quality VAS scores increased in both nostrils (P < 0.001). Transverse measurements between the upper canines (C-C), premolars (PM-PM), and molars (M-M), and maxillary perimeter showed significant increases (P < 0.001), while the anteroposterior maxillary arch length showed a significant decrease (P = 0.016). An inverse proportional correlation was found between PM-PM and nasal airway resistance (r = -0.395; P = 0.034) and between M-M and nasal airway resistance (r = -0.383; P = 0.040). These results demonstrate that surgically expanding the posterior region of the maxilla results in decreased nasal airway resistance, decreased obstructive symptoms, and improved patient respiratory quality.

RESUMO

The present study aims at contributing to the knowledge of the spatial variability of coralligenous reefs through the evaluation of patterns ranging from local to biogeographic scale around the island of Sardinia. The coralligenous reef assemblages of six areas were studied through a hierarchical sampling design: three sites per area were selected, in each site three plots were sampled and in each plot ten photographic samples were collected. The structure of coralligenous reefs across closed biogeographic regions is described, highlighting that nearly pristine assemblages, although characterized by similar high diversity, can be either dominated by animals, such as gorgonians and bryozoans, or macroalgae. The observed variations seem largely related to biogeographic patterns rather than spatial distance, supporting the need to identify specific reference conditions to assess the ecological quality of this habitat depending on the biogeographic area to be monitored.

RESUMO

OBJECTIVE: The study aimed to explore premorbid academic and social functioning in patients with schizophrenia, and its associations with the severity of negative symptoms and neurocognitive impairment. METHOD: Premorbid adjustment (PA) in patients with schizophrenia was compared to early adjustment in unaffected first-degree relatives and healthy controls. Its associations with psychopathology, cognition, and real-life functioning were investigated. The associations of PA with primary negative symptoms and their two factors were explored. RESULTS: We found an impairment of academic and social PA in patients (P ≤ 0.000001) and an impairment of academic aspects of early adjustment in relatives (P ≤ 0.01). Patients with poor PA showed greater severity of negative symptoms (limited to avolition after excluding the effect of depression/parkinsonism), working memory, social cognition, and real-life functioning (P ≤ 0.01 to ≤0.000001). Worse academic and social PA were associated with greater severity of psychopathology, cognitive impairment, and real-life functioning impairment (P ≤ 0.000001). Regression analyses showed that worse PA in the academic domain was mainly associated to the impairment of working memory, whereas worse PA in the social domain to avolition (P ≤ 0.000001). CONCLUSION: Our findings suggest that poor early adjustment may represent a marker of vulnerability to schizophrenia and highlight the need for preventive/early interventions based on psychosocial and/or cognitive programs.

RESUMO

Abstract NUMEN proposes cross sections measurements of Heavy-Ion double charge exchange reactions as an innovative tool to access the nuclear matrix elements, entering the expression of the life time of Neutrinoless double beta decay (0νββ). A key aspect of the projectis the use at INFN-Laboratori Nazionali del Sud (LNS) of the Superconducting Cyclotron (CS) for the acceleration of the required high resolution and low emittance heavy-ion beams and of MAGNEX large acceptance magnetic spectrometer for the detection of the ejectiles. The experimental measurements of double charge exchange reactions induced by heavy ions present a number of challenging aspects, since such reactions are characterized by very low cross sections. First experimental results give encouraging indication on the capability to access quantitative information towards the determination of the Nuclear Matrix Elements for 0νββ decay.


Resumen NUMEN propone mediciones de secciones eficaces de reacciones de intercambio de carga doble de iones pesados como una herramienta innovadora para acceder a los elementos de la matriz nuclear, entrando en la expresión del tiempo de vida de la desintegración beta doble sin neutrino (0νββ). Un aspecto clave del proyecto es el uso en INFN-Laboratori Nazionali del Sud (LNS) del ciclotrón superconductor (CS) para la aceleración de los haces de iones pesados de alta resolución y baja emitancia requeridos y del espectrómetro magnético de gran aceptación MAGNEX para la detección de los residuos eyectados. Las mediciones experimentales de reacciones de intercambio de carga doble inducidas por iones pesados presentan una serie de aspectos desafiantes, ya que tales reacciones se caracterizan por secciones eficaces muy bajas. Los primeros resultados experimentales dan una indicación alentadora sobre la capacidad de acceder a información cuantitativa para la determinación de los Elementos de la Matriz Nuclear para la descomposición de 0νββ.

RESUMO

BACKGROUND: This study aimed to assess clinical outcomes of long-term low-dose oral doxycycline therapy in difficult-to-treat chronic rhinosinusitis with polyps (CRSwNP). METHODS: This was a prospective, open-label study of 60 patients with difficult-to-treat CRSwNP who had undergone endoscopic sinus surgery. Patients were divided into two groups: 28 received nasal steroids, saline irrigation, and doxycycline (200 mg on the first day, followed by 100 mg once daily) for 12 weeks, while 30 received only nasal steroids and saline irrigation. The main outcome measure was an adequate effect size of doxycycline treatment on clinically meaningful significant improvement of SNOT-20. Other outcome measures were the SNOT-20, NOSE, and Lund-Kennedy scores. The following parameters were also analyzed: asthma, rhinitis, non-steroidal-exacerbated respiratory disease (NERD), and baseline serum IgG, IgA, IgE, IgM, ANCA, and eosinophil count. RESULTS: There was an adequate effect size of doxycycline treatment on clinically meaningful significant improvement of SNOT-20. Patients who received doxycycline also had significantly better outcomes regarding SNOT-20, NOSE, and Lund-Kennedy scores. There was a negative association among a clinically significant improvement of SNOT-20 and presence of asthma, NERD, and elevated serum IgE levels before treatment. CONCLUSION: These findings suggest that doxycycline may have a beneficial role for CRSwNP patients, especially for patients without asthma, NERD or high levels of serum IgE before treatment.

RESUMO

BACKGROUND: The study aimed to subtype patients with schizophrenia on the basis of social cognition (SC), and to identify cut-offs that best discriminate among subtypes in 809 out-patients recruited in the context of the Italian Network for Research on Psychoses. METHOD: A two-step cluster analysis of The Awareness of Social Inference Test (TASIT), the Facial Emotion Identification Test and Mayer-Salovey-Caruso Emotional Intelligence Test scores was performed. Classification and regression tree analysis was used to identify the cut-offs of variables that best discriminated among clusters. RESULTS: We identified three clusters, characterized by unimpaired (42%), impaired (50.4%) and very impaired (7.5%) SC. Three theory-of-mind domains were more important for the cluster definition as compared with emotion perception and emotional intelligence. Patients more able to understand simple sarcasm (⩾14 for TASIT-SS) were very likely to belong to the unimpaired SC cluster. Compared with patients in the impaired SC cluster, those in the very impaired SC cluster performed significantly worse in lie scenes (TASIT-LI <10), but not in simple sarcasm. Moreover, functioning, neurocognition, disorganization and SC had a linear relationship across the three clusters, while positive symptoms were significantly lower in patients with unimpaired SC as compared with patients with impaired and very impaired SC. On the other hand, negative symptoms were highest in patients with impaired levels of SC. CONCLUSIONS: If replicated, the identification of such subtypes in clinical practice may help in tailoring rehabilitation efforts to the person's strengths to gain more benefit to the person.

RESUMO

BACKGROUND AND PURPOSE: Patients with vascular parkinsonism have higher cognitive decline and more basal ganglia lesions. We aimed to evaluate the relationship of cognitive impairment with functional connectivity between the basal ganglia and cingulate cortex in vascular parkinsonism. MATERIALS AND METHODS: Thirty patients (8 with vascular parkinsonism and 22 with Parkinson disease) and 23 controls were enrolled. The Mattis Dementia Rating Scale and the Stroop Task were used to assess cognitive decline. MR imaging examinations included T1-MPRAGE, FLAIR, and resting-state fMRI sequences. MPRAGE was segmented to obtain basal ganglia and cingulate cortex volumes. FLAIR was segmented to obtain white matter hyperintensity lesion volume. Resting-state fMRI sequences were used to compare basal ganglia functional connectivity with the cingulate cortex between patients and controls. RESULTS: Patients with vascular parkinsonism exhibited impaired attention, resistance to interference, and inhibitory control and an increased number of errors on the Stroop Task. They also had higher caudate nucleus and white matter hyperintensity lesion volumes, which were positively correlated (ρ = 0.75, P < .0001). Caudate nucleus functional connectivity with the perigenual anterior cingulate cortex was increased in patients with vascular parkinsonism compared with controls and patients with Parkinson disease, and it was positively correlated with the caudate nucleus volume (ρ = 0.44, P = .016). Caudate nucleus functional connectivity with the posterior cingulate cortex was decreased in patients with vascular parkinsonism compared with controls and negatively correlated with the number of errors on the Stroop test (ρ = -0.51, P = .0003). CONCLUSIONS: In patients with vascular parkinsonism, cognitive decline could be related to changes of caudate nucleus functional connectivity with the cingulate cortex at resting-state, which may be induced by ischemia-related remodelling.

RESUMO

AIMS: This article aims to (1) explore the levels of perceived insecurity in a sample of patients with mood or anxiety disorders and (2) assess whether living in 'big cities' can influence the levels of patients' perceived insecurity and social contacts compared to living in a non-urbanized context. METHODS: A total of 24 Italian mental health centers (MHCs) have been invited to participate. Twenty patients consecutively accessing the MHC have been recruited. All patients have been assessed using validated assessment tools. RESULTS: The sample consisted of 426 patients, mostly female, with a mean age of 45 years. Globally, 52.2% of patients had a diagnosis of mood disorders, and 37.8% had anxiety disorders. Half of the sample declared that the main feeling toward life is uncertainty; higher levels of pessimistic views toward life have been detected in patients living in urban areas. A positive association between negative attitudes toward life and higher levels of depressive and anxiety symptoms, poor social functioning and higher levels of perceived psychological distress has been found. CONCLUSION: Our findings confirm the presence of a common sense of perceived uncertainty among our sample. Such attitude toward life can have a detrimental impact on patients' psychological and physical well-being, contributing to high levels of distress.

RESUMO

INTRODUCTION: Studies designed to investigate chronic rhinosinusitis (CRS) epidemiology play an important role to assess population`s distribution and risk factors to result in the development and promotion of public health policies. METHOD: This study design is a survey carried out with a complex two-stage cluster sampling plan. Personal interviews were carried out with 2,003 individuals. The questionnaire included the epidemiological criteria for CRS. Demographic data, history of physician-diagnosed respiratory diseases (asthma, sinusitis, rhinitis), smoking, family income, educational attainment, and household characteristics were also evaluated. RESULTS: The overall response rate was 93.9% of the households. Mean age was 39.8 +- 21 years; 45.33% were male. The overall prevalence of CRS in the city of Sao Paulo was 5.51%. We found a significant association between diagnosis of CRS and diagnosis of asthma and CRS and diagnosis of rhinitis and a significant association between presence of CRS and belonging to the low-income subgroup. CONCLUSION: The municipality of Sao Paulo has an urban population of 11 million. According to the present study, the prevalence of CRS is 5.51%, which represents more than 500,000 individuals affected by this condition in the city.

RESUMO

INTRODUCTION: Juvenile angiofibromas (JA) are highly vascular, benign tumours for which surgery is the treatment of choice. In most services, embolisation is performed prior to resection. Nevertheless, there are few data on the complications of preoperative embolisation for JA. AIM: To describe major and minor complications of preoperative embolisation in a 32-year experience of patients undergoing surgical resection of JA at a tertiary hospital. METHODS: Retrospective chart review study of 170 patients who underwent surgical resection of JA at a tertiary hospital between September 1976 and July 2008. RESULTS: All patients were male. Age ranged from 9 to 26 years. Ninety-one patients had no complications after embolisation. Overall, 105 complication events occurred of which four major and 101 minor. CONCLUSION: In our series, preoperative embolisation for JA produced no irreversible complications and no aesthetic or functional sequelae. The vast majority of complications were transient and amenable to clinical management.

RESUMO

The present study sought to assess nasal respiratory function in adult patients with maxillary constriction who underwent surgically assisted rapid maxillary expansion (SARME) and to determine correlations between orthodontic measurements and changes in nasal area, volume, resistance, and airflow. Twenty-seven patients were assessed by acoustic rhinometry, rhinomanometry, orthodontic measurements, and use of a visual analogue scale at three time points: before surgery; after activation of a preoperatively applied palatal expander; and 4 months post-SARME. Results showed a statistically significant increase (p<0.001) in all orthodontic measurements. The overall area of the nasal cavity increased after surgery (p<0.036). The mean volume increased between assessments, but not significantly. Expiratory and inspiratory flow increased over time (p<0.001). Airway resistance decreased between assessments (p<0.004). Subjective analysis of the feeling of breathing exclusively through the nose increased significantly from one point in time to the next (p<0.05). There was a statistical correlation between increased arch perimeter and decreased airway resistance. Respiratory flow was the only variable to behave differently between sides. The authors conclude that the SARME procedure produces major changes in the oral and nasal cavity; when combined, these changes improve patients' quality of breathing.

RESUMO

BACKGROUND: The Authors sought to evaluate current prevalence of mental disorders in patients affected by metabolic syndrome compared with patients affected by central obesity alone. METHODS: 186 (63.5%) patients affected by central obesity and 107 (36.5%) affected by metabolic syndrome according to ICF criteria were interviewed by means of SCID I. RESULTS: Axis I current prevalence was respectively 45.7% and 44.9% among patients with central obesity and patients with metabolic syndrome, differences which were not significant. No statistically significant differences were found between groups as far as each single axis I diagnostic category was concerned. Moreover, current prevalence of any axis I, anxiety and mood disorders were independent of the number of components of metabolic syndrome. CONCLUSION: metabolic syndrome is associated to an higher risk for current mental disorders, which seems to be mainly due to the strong association of central obesity to psychopathology.

RESUMO

INTRODUCTION: The present study aims to evaluate effectiveness of antipsychotics in a cohort of chronic outpatients affected by schizophrenia and related disorders. MATERIALS AND METHODS: Three hundred chronic patients affected by schizophrenia (n=173), schizoaffective (n=117) and delusional (n=60) disorder who were in treament with antipsychotics on 1.3.2008 were considered in the study; effectiveness of antipsychotic treatment was evaluated by means of rates of all cause discontinuation in a 12 months period (31.3.2008-31.3.2009) and of "overall duration of treatment" (DT) (duration of treatment retrospectively evaluated on the basis of clinical records+duration of treatment prospectively evaluated during the 12-months follow up). RESULTS: Discontinuation of treatment was registered in 25% of patients (29% due to side effects, 14% due to scarce adherence, 11% due to lack of efficacy, 22% due to more causes). Clozapine (7%), Risperidon Long-acting (10%), Typical Antipsychotics depot (11%) and Olanzapine were associated to lower rates of all causes discontinuation. Overall mean duration of antipsychotic treatment was 18± 32 months, with statistically significant differences between drugs (F=4.65, p=0.000). Clozapine (65 mo), Olanzapine (50 mo), butyrophenones (49 mo), typical antipsychotics depot (48 mo), and risperidone (47.5 mo) were the antipsychotics with a longer duration of treatment. Only Clozapine showed a significantly longer DT than any other antipsychotic medication excluding buthyrrohenones. CONCLUSIONS: Rates of all cause discontinuation of antipsychotics appear to be somewhat lower than expected on the basis of pragmatic studied published in the last years; similarly overall duration of treatment seems to be longer. Clozapine is associated to a higher overall effectiveness respect to any other atypical antipsychotic.

RESUMO

OBJECTIVE: The relationship between psychopathology and alexithymia in obese patients is uncertain. The present study was performed to evaluate this relationship in a clinical sample of patients attending a centre for the diagnosis and treatment of obesity compared to a matched sample of non-obese subjects. METHODS: 293 consecutive obese patients (48 males, 245 females, mean age 45, 41±13.55 yrs; mean BMI 35.60±6.20) were compared with a control group made of 293 non-obese subjects (48 males, 245 females, mean age 45, 66±13.86 yrs; mean BMI 21.8±2.06); all subjects were interviewed by means of SCID I and SCID II together with several self-evaluation instruments including the TAS-20 (Toronto Alexithymia Scale) and SCL-90 (Symptom Check List, Revised). RESULTS: Alexithymia was significantly more frequent among obese patients compared to "normal" controls (12.9% vs 6.9%, p=0.010); moreover obese patients achieved significantly higher mean scores on subscales 1 and 2 and on overall scale of the Toronto Alexithymia Scale; comorbidity with axis I/II disorders, in particular Binge Eating Disorder, was associated with a significantly higher frequency of alexithymic traits and higher scores at TAS. CONCLUSIONS: Alexithymia and psychopathology are strongly correlated among obese patients seeking treatment. Routine evaluation of personality traits and comorbid psychopathology may be relevant in treatment of obesity.

RESUMO

OBJECTIVE: The authors sought to evaluate lifetime prevalence of mental disorders in patients affected by metabolic syndrome compared with patients affected by central obesity alone. METHODS: One hundred eighty-six (63.5%) patients affected by central obesity and 107 (36.5%) affected by metabolic syndrome according to ICF criteria were interviewed by means of SCID I and SCID II. RESULTS: Axis I and axis II lifetime prevalence were respectively 53.8% and 30.1% among patients with central obesity, 50.5% and 28% among patients with metabolic syndrome, differences which were not significant. No statistically significant differences were found between groups as far as each single axis I and II diagnostic category was considered. CONCLUSION: Metabolic syndrome is not associated with a higher risk of mental disorders compared to central obesity alone.

RESUMO

BACKGROUND AND AIMS: Previous studies indicate unrestrained cell cycle progression in liver lesions from hepatocarcinogenesis-susceptible Fisher 344 (F344) rats and a block of G(1)-S transition in corresponding lesions from resistant Brown Norway (BN) rats. Here, the role of the Forkhead box M1B (FOXM1) gene during hepatocarcinogenesis in both rat models and human hepatocellular carcinoma (HCC) was assessed. METHODS AND RESULTS: Levels of FOXM1 and its targets were determined by immunoprecipitation and real-time PCR analyses in rat and human samples. FOXM1 function was investigated by either FOXM1 silencing or overexpression in human HCC cell lines. Activation of FOXM1 and its targets (Aurora Kinose A, Cdc2, cyclin B1, Nek2) occurred earlier and was most pronounced in liver lesions from F344 than BN rats, leading to the highest number of Cdc2-cyclin B1 complexes (implying the highest G(2)-M transition) in F344 rats. In human HCC, the level of FOXM1 progressively increased from surrounding non-tumorous livers to HCC, reaching the highest levels in tumours with poorer prognosis (as defined by patients' length of survival). Furthermore, expression levels of FOXM1 directly correlated with the proliferation index, genomic instability rate and microvessel density, and inversely with apoptosis. FOXM1 upregulation was due to extracellular signal-regulated kinase (ERK) and glioblastoma-associated oncogene 1 (GLI1) combined activity, and its overexpression resulted in increased proliferation and angiogenesis and reduced apoptosis in human HCC cell lines. Conversely, FOXM1 suppression led to decreased ERK activity, reduced proliferation and angiogenesis, and massive apoptosis of human HCC cell lines. CONCLUSIONS: FOXM1 upregulation is associated with the acquisition of a susceptible phenotype in rats and influences human HCC development and prognosis.

RESUMO

BACKGROUND: Obesity seems to be very frequent among schizophrenics, partly due to psychotropic medications. To examine this possibility the authors compared the distribution of Body Mass Index and of Abdominal Obesity among an outpatient sample of schizophrenics, comparing their data with those of the Italian population as a whole. MATERIALS AND METHODS: Weight, height, BMI and waist circumference were evaluated in 126 schizophrenic spectrum outpatients (51 F; 75 M, mean age 43.7 +/- 13.3 yrs) receiving treatment in a university community mental health centre. RESULTS: Mean BMI of the sample was 26.8 +/- 4.9,without any significant difference between genders (females = 25.9 +/- 4.9; males = 27.4 +/- 4.9). The prevalence of obesity (BMI>or=30) in the sample was 26.2%, 2.8 times higher that of Italian average (9.8%). 46.8% out of the patients was affected by abdominal obesity measuring waist circumference, a prevalence 1.7 times higher that of the Italian average (31%). Abdominal obesity was significantly more frequent among females (F = 60.5%; M= 37.3%, p 0.05). 53% out of those patients who were under treatment with atypical antipsychotics respect to 25% of those who were not under treatment (p>0.05) and 71% of those who were submitted to an association of typical and atypical antipsychotics respect to those patients who were not treated with this association (p 0.05) were affected by abdominal obesity. CONCLUSIONS: Also in Italy schizophrenic were found more frequently obese than the corresponding general population. Female schizophrenics and patients who undergone treatment with atypical antipsychotics or with the combination of typical and atypical antipsychotics were significantly more at risk for abdominal obesity.

RESUMO

AIM: The aim of this study was to define the role of endorectal ultrasound in the evaluation of transphincteric fistula-in-ano treated with a seton. METHODS: Fifty-one patients affected by complex fistula-in-ano and treated with the application of a drain seton at the Second Unit of General Surgery of the University of Cagliari were recruited for the study. Clinical and ultrasonographic (US) evaluation, with transanal scans, were performed in each case before operation. Intraoperative demonstration of a transphincteric track was an indication for a partial fistulotomy with the application of a seton, tied up loosely around the external sphincter. If clinical and US evaluation, during follow-up, revealed a good drainage of the fistula by the seton and its superficialization, definitive fistulotomy was performed. RESULTS: Endoanal US had an 88.2% accuracy. Sclerosis around the seton was observed in 9 patients (17.6%); in other 9 cases a surgical toilette of the track was necessary because of the bad drainage carried out by the seton. Definitive fistulotomy was performed in 35 patients, whilst 16 are still bearer of the seton. After a mean follow-up of 39.5 months, 1 recurrence (2.9%) has occurred. Functional results were satisfactory: 55.9% of the patients has a perfect continence and 88.2% has a Wexner's incontinence score of up to 5. CONCLUSIONS: At skilled institutions, endoanal ultrasound allows to optimize the therapy of transphincteric fistula-in-ano treated with a seton and contribute to obtain good results in terms of recurrence and functional outcomes.

RESUMO

Five patients (4 women) with Parkinson's disease (PD) and primary major psychiatric disorder (PMPD) meeting DSM-IV criteria for the diagnosis of bipolar affective disorder (BAD) were studied. Four patients had early onset PD. Four developed a severe psychiatric disorder a few years after starting dopaminergic therapy in presence of a mild motor disability and a mild cognitive impairment, with no evidence of cerebral atrophy at CT or MRI. Two patients developed a clear manic episode; the other three presented a severe depressive episode (in one case featuring a Cotard syndrome). None showed previous signs of long term L-dopa treatment syndrome (LTS), hallucinosis or other minor psychiatric disorders. The two manic episodes occurred shortly after an increase of dopaminergic therapy and in one case rapid cyclic mood fluctuations were observed. At the onset of psychiatric symptoms, all patients had an unspecific diagnosis of chronic delusional hallucinatory psychosis (CDHP).
