Cognitive remediation for the treatment of neuropsychological disturbances in subjects with euthymic bipolar disorder: findings from a controlled study.

INTRODUCTION: Individuals with euthymic Bipolar Disorder (BD) can experience deteriorated cognitive functioning, with such deterioration being associated with functional impairment. Cognitive remediation (CR) is considered an effective add-on intervention for neuropsychological impairments, but relatively few CR controlled studies have been performed on BD. In the present study the efficacy of a CR intervention designed for the improvement of cognition and functioning in patients with euthymic BD was tested. METHODS: Patients (n = 54) with euthymic BD were assigned to receive active (n = 27) or control (n = 27) intervention. The active intervention (i.e. the Cognitive Remediation in Integrated Treatment - CRIIT - protocol) was made of 20 individual sessions focused on the treatment of attention, memory and executive functioning through the COGPACK software; each session was integrated with psychoeducation and rehabilitation interventions implemented through a metacognitive approach aimed at ameliorating personal agency. RESULTS: A significant (p ≤ 0.015) time x group interaction at repeated measures MANOVA was observed on Rey Auditory Verbal Learning Test, Rey Complex Figure Test, Wisconsin Card Sorting Test, Trail Making Test, Visual Search, Life Skills Profile, and Barratt Impulsiveness Scale. LIMITATIONS: A single-blind approach was used. DISCUSSION: The results showed that patients undergoing active intervention improved in domains related to executive functions, attention, memory, functioning and impulsivity more significantly than patients undergoing control interventions. This study adds to the evidence that CR improves neurocognition in BD, and suggests that CRIIT protocol represents an add-on intervention of potential relevance to increase cognition and functioning in BD euthymic patients.

[Experience of group art therapy with music improvisation in the integrated treatment at a psychiatric Day Hospital: preliminary results]. / Esperienza di arteterapia di gruppo con improvvisazione musicale nel trattamento integrato riabilitativo presso un Day Hospital psichiatrico: risultati preliminari.

AIM: The study aims at evaluating the resocializing effects of music therapy as add-on therapy in the course of integrated, pharmacological and psychological, treatment. METHODS: During a six months period, 24 patients belonging to a psychiatric Day Hospital were recruited and divided into 2 groups. An accurate music anamnesis was collected for each patient. Group 1 (n=11) received as add-on therapy 14 improvisational music therapy sessions on a weekly basis, while group 2 (n=13) received 7 improvisational music therapy sessions alternated with 7 listening music therapy sessions, on a weekly basis. The response to music therapy was evaluated at the beginning and at the end of the add-on therapeutic process through a music therapy observation form consisting of 9 variables. RESULTS: In both groups there was a good response from patients affected by mood disorders as well as obsessive-compulsive disorder, while schizophrenic patients response was either absent or reduced. The improvement of the variable interaction between the components, sharing of the instrument, facial expressions and tension was significantly higher in the group that received as add-on therapy both improvisational music therapy and listening music therapy. DISCUSSION AND CONCLUSIONS: The findings suggest a significant role of the improvisational music therapy in gaining a re-socializing effect within a therapeutic group. The effectiveness turns out to be greater if the improvisation is combined with a listening therapy, aimed at educating the patient to a greater openness to the expressive aspect of sound. The active-passive music therapy association could then bring a valuable contribution as an add-on rehabilitative treatment.

[Effects of Group Psychoeducation on stress reactivity neuroendocrine profile in stabilized bipolar patients. A controlled study]. / Effetti della psicoeducazione di gruppo sul profilo neuroendocrino di reattività allo stress in pazienti bipolari stabilizzati. Uno studio controllato.

INTRODUCTION: Patients with bipolar disorder show a high relapse rate generally related to their poor adherence to the prescribed medications and to their high stress vulnerability, linked to genetic, neuroendocrine and cognitive factors. AIMS: The first aim of this study was to verify if for a group of pharmacologically stabilized bipolar patients, the attendance to a Group Psychoeducation program according to the Barcelona model would result in an improvement of their stress resilience, as measurable by evaluating their morning cortisol secretory profile. The second aim of the study has been to verify if these effects would maintain stable over time, organizing follow-up evaluations, after one year and after two years form the end of the group psychoeducation program. MATERIALS AND METHODS: 96 patients who had been euthymic for at least 6 months and were under stabilized pharmacologic maintenance treatment, were randomized in two groups: pharmacological treatment as usual (TAU) or pharmacological treatment plus group Psychoeducation (PE). Patients in both groups underwent a psychological assessment (HAMD, YMRS e ARMS), and to a functional assessment of the HPA axis activity, obtained evaluating cortisol levels from salivary samples collected in 5 different moments of the day: at baseline, at the end of the group psychoeducation program, and after 1 year and 2 years from the end of the last PE session. RESULTS: At the end of the study, both groups (PE and TAU) did not show any significant intergroup difference with regard to all the clinical variables and the patients' adherence to the prescribed medications. On the contrary, significative intergroup differences were observed with regard to morning cortisol secretory profile, that was found normalized at the endpoint only among patients of the PE group, but not among those of the TAU group. This normalization of the morning cortisol secretory profile observed among patients of the PE group, proved to maintain stably overtime, since it was observed also in the two follow-up assessments, organized after 1 year and after 2 year from the end the treatment. DISCUSSION: Data collected in this study may indicate that the efficacy of the psychoeducation programs for bipolar patients may activate an improvement of the functional activation of the HPA axis, and so obtaining a reduction of their stress vulnerability.

Relational variables in short-term psychodynamic psychotherapy: an effectiveness study.

This study examined associations between specific elements of therapeutic relationships and short-term psychodynamic psychotherapy (STPP) outcomes. Notably, we focused on therapists' subjective experiences during their first clinical interaction with patients, countertransference patterns and therapeutic alliance evaluated early in treatment, in relation to patient symptom changes at the end of STPP. Twenty clinicians completed the Comprehensive Psychopathological Rating Scale to evaluate patients' (N=32) symptom severity at the beginning and end of STPP. They also completed the Assessment of Clinicians' Subjective Experience (ACSE) to assess their subjective experiences of their patients at the first clinical interview and the Therapist Response Questionnaire (TRQ) and Working Alliance Inventory to evaluate their countertransference reactions and therapeutic alliance at the sixth therapy session. The findings showed that the TRQ and ACSE scales correlated in a coherent way, with the exception of the TRQ helpless/inadequate pattern and ACSE impotence. Strong and more negative TRQ countertransference patterns and ACSE dimensions were significantly associated with lower quality of the therapeutic alliance. Finally, better STPP outcomes were positively associated with a good therapeutic alliance and negatively correlated with greater difficulty in attunement at the beginning of clinical assessment and therapists' stronger responses of helplessness, frustration, and disengagement during therapy. These results confirm the precious value of the clinical relationship, which represents a useful source of information for therapists when planning therapeutic interventions.

A preliminary study on hot and cool executive functions in bipolar disorder and on their association with emotion regulation strategies.

OBJECTIVE: Individuals with bipolar disorder (BD) experience difficulties in cognitive and emotional regulation in different phases of illness. In the present study, we aimed at exploring differences on hot and cool executive functioning (EF) between BD patients in euthymia (BDe) and mania (BDm), and associations of hot and cool EF with emotion regulation strategies. METHODS: Thirty-seven BD patients (among which 18 with a current manic episode and 19 in euthymia) and 15 healthy controls completed a battery of tests assessing hot and cool EF and emotion regulation strategies. RESULTS: Between group comparisons showed that in all the explored hot dimensions BDm subjects had significantly worse performances than BDe subjects, while in all the explored cool dimensions BDm subjects had significantly worse performances than HC subjects, with BDe patients having an intermediate profile. Results from bivariate correlations among BDe subjects (but not among BDm subjects) showed significant positive correlations (i) between elements of hot EF and elements of cool EF, and (ii) between cognitive reappraisal emotional regulation strategy and planning (i.e., a measure of cool EF), as well as a significant negative correlation between expressive suppression emotional regulation strategy and emotional intelligence. CONCLUSIONS: The results confirm previous findings on a role of impaired EF in BD, and suggest (i) that hot EF is more closely related to mood (i.e., state-dependant) than cool EF, and (ii) that BD patients can more effectively use emotion regulation strategies in association with EF during euthymia than during mania.

[Cinema-based interventions implemented at the Day Hospital of Sapienza University of Rome - Policlinico Umberto I Hospital: group therapy, projective evaluation, psychoeducation and treatment] / Il cinema nella pratica psichiatrica: intervento di gruppo, test proiettivo, elemento di psicoeducazione, terapia. L'esperienza del Day Hospital del Policlinico Umberto I - Sapienza Università di Roma.

Cinema has been extensively used in psychiatric care. In the present article the cinema-based interventions implemented at the Day Hospital of Sapienza University of Rome - Policlinico Umberto I Hospital with various modalities and aims (e.g. rehabilitation, group therapies, projective evaluations, psychoeducation) will be discussed.

Psychoeducational intervention focused on healthy living improves psychopathological severity and lifestyle quality in psychiatric patients: preliminary findings from a controlled study.

BACKGROUND: Individuals with psychiatric disorders incur an increased risk of morbidity and mortality, with higher prevalence of cardio-metabolic risk factors s largely contributing to a significant reduction in life expectancy. OBJECTIVES: The aim of the present study was at evaluating the clinical effectiveness of an educational intervention targeting lifestyle habits in patients with mood and psychotic disorders. METHODS: Patients (n = 32) were randomly assigned to receive, in addition to the pharmacological treatment, either five sessions of group psychoeducation focused on healthy lifestyle or five sessions of a control group therapy. RESULTS: Both psychopathological severity (i.e. the brief psychiatric rating scale) and lifestyle quality (i.e. physical activity, sleep quality and adherence to the Mediterranean diet) improved significantly over time in patients who underwent specific psychoeducational sessions but not in the controls. CONCLUSIONS: These findings add to the accumulating evidence that educational interventions focused on lifestyle habits can ameliorate general and mental health in patients with psychiatric disorders and suggest that educational programs represent an effective non-pharmacological intervention to manage drug-induced cardiometabolic disturbances.

Influence of Normo- and Hypogonadal Condition, Hyperuricemia, and High-Fructose Diet on Renal Changes in Male Rats.

Background. There is a gender disparity in the incidence, prevalence, and progression of renal disease. The object of this paper is to evaluate the presence and type of renal lesion in normogonadic and hypogonadic male rats in a mild hyperuricemia induced condition and exposed to a high-fructose diet. Methods. 56 adult male Wistar rats were used. Animals were divided into two groups, one normogonadic (NGN) and one hypogonadic (HGN), and each group was divided into four subgroups in accordance with the treatment: control with only water (C), fructose (F), oxonic acid (OA), and fructose + oxonic acid (FOA). Renal changes were evaluated by measuring glomerulosclerosis, fibrosis, and arteriolar media/lumen (M/L) ratio. Results. The OA and FOA groups presented significantly hypertension (p < 0.001). The OA group significantly increased (p < 0.05) the percentage of glomerulosclerosis as well as the FOA group (p < 0.001). When comparing NGN versus HGN, we observed a trend to a lower glomerulosclerosis in the latter. A higher arteriolar M/L ratio was observed in the OA (p < 0.05) and FOA (p < 0.001). Conclusion. Hyperuricemia conditions and a high-fructose diet favor blood pressure increase together with changes in the arteriolar media/lumen ratio and renal glomerular damage. These changes were more apparent in normogonadic animals.

[History of Clinical Psychiatry of Sapienza University of Rome in Policlinico Umberto I]. / Storia della Clinica Psichiatrica della Sapienza Università di Roma nel Policlinico Umberto I.

The present article intends to go over the history of the Psychiatric Clinic of the Sapienza University of Rome, starting from the beginning of the teaching of Psychiatry at Santa Maria della Pietà mental hospital, back in 1871, to the eventual founding, at the University "La Sapienza" and the Umberto I general hospital, of the Institute of Psychiatric Clinic and next of the Nervous and Mental Diseases' Clinic with the enclosed specialization school in Psychiatry. A detailed overview is supplied on the characters of the eminent scientists who have succeeded over time at the head of the Clinic and on the description of its different organization, conceived by each of them because of their educational and cultural roots. In this humus is born, in 1966, the journal Rivista di Psichiatria, still alive. To follow, a brief description of what the academic Psychiatry of the Umberto I nowadays represents, and indeed point of contact of different psychiatric thinking roots, with an organic, pharmacological, phenomenological, and psychotherapeutic orientation, this latter in the psychodynamic, cognitive-behavioral, and family-related approaches.

[Osteoporosis and major depression: open debate on a bidirectional relationship]. / La relazione bidirezionale tra osteoporosi e depressione maggiore: un dibattito aperto.

Osteoporosis and depression are two chronic diseases that affect large population groups with great impact on morbidity, mortality and quality of life. Existing studies of the relationship between depression and osteoporosis have been heterogeneous in their design and use of diagnostic instruments for depression, which might have contributed to the different results on the comorbidity of these two conditions. Moreover, the direction of the causative link is still controversial and the etiology remains unclear. Definitely, limited data suggest that osteoporosis may enhance depressive symptoms, while far more studies have shown that depression adversely affects bone density and increases fracture risk. Thus the correlation of these diseases is still under research. This review comments on a plausible causative relationship and underlying mechanisms that might elucidate the link between two very common diseases. We describe the possible impact of osteoporosis on moods and the effect of depression on bone health. In particular, we focus on the role of the hypothalamic-pituitary-adrenocortical and sympathoadrenal axes, of the parathyroid hormone and cytokines. We also describe the effect of the antidepressant drugs as well as lifestyles that may explain this effect.

[Coffee consumption in depressive disorders: it's not one size fits all]. / Consumo di caffè nei disturbi depressivi: una dose giusta, non per tutti.

Caffeine is considered the world's most popular psychoactive substance. Its actions on the central nervous system, mainly mediated by antagonism of adenosine receptors and subsequent modulation of dopaminergic activity, would be particularly sought by depressed patients, as an attempt of self-medication. However, published data suggested that coffee consumption may worsen psychopathological conditions in mood disorders. Thus, we reviewed available evidence in the literature that investigated the effects of coffee consumption on clinical development of underlying psychopathology. Literature research was done by typing on Medline/PubMed and PsychINFO the key words "coffee AND major depression", "coffee AND dysthymia". The research was limited to English language publications and to studies conducted exclusively on humans. Although literature data are conflicting, extensive follow-up studies indicate a significant caffeine effect on risk reduction of developing clinical depression symptoms. Clinical worsening was observed mainly in cases of postpartum depression and comorbid panic disorder. Taking in account the study limitations, we observed a biphasic profile in caffeine psychostimulant effect: low to moderate doses may correlate with a reduction in depressive risk in healthy subjects and an improvement of many clinical symptoms (attention, arousal, psychomotor performance) in depressed patients, whereas the assumption of high doses may result in thymic dysregulation, favor mixed affective states and worsen circadian profiles and anxiety symptoms.

[Comorbidity of hysterical pathologies associated with gynecological diseases: historical perspectives and current evidence]. / Comorbilità di patologie dello spettro isterico con patologie dell'apparato ginecologico: nozioni storiche ed evidenze attuali.

BACKGROUND: In spite of a large amount of observations made in Psychiatric Day-Hospital of Sapienza University of Rome relating to comorbidity between sexual and gynecological disorders and hysteria, we have attempted to quantify the incidence of this phenomenon in order to assess their significance. METHODS: A retrospective study was conducted on medical records of patients hospitalized at the Day-Hospital of the Policlinico Umberto I in Rome between 1989 and 2009. RESULTS: It seems to be confirmed the hypothesis of a high frequency of correlating these disorders, although the results lead to a number of critical reflections on its significance and the method adopted. CONCLUSIONS: This research needs larger and more accurate future investigations, cause the type of study was made without direct information.

Magnetic resonance imaging and ultrasound evaluation after breast autologous fat grafting combined with platelet-rich plasma.

BACKGROUND: Breast lipofilling is a fairly simple and safe procedure if it is performed by experienced surgeons. METHODS: The authors evaluated the radiologic findings from 24 breasts (15 women) subjected to a lipofilling procedure (two sessions) for corrective surgery or cosmetic reasons. Mammography, ultrasound, and magnetic resonance imaging were performed before the first lipofilling session (T0) and 12 months after the last session (T12); ultrasound and magnetic resonance imaging were used 3 months after the first session (Ti) and 3 and 6 months after the last session (T3 and T6). Volumetric evaluations were also made through three-dimensional magnetic resonance imaging reconstruction. RESULTS: Ultrasound showed oily cysts in 66.67 percent of the breasts at Ti, 70.83 percent at T3, 62.5 percent at T6, and 45.83 percent at T12, whereas magnetic resonance imaging detected oily cysts in 8.33 percent at Ti and T3 and T6 months and 4.17 percent at T12. At Ti, T3, and T6, the cytosteatonecrotic areas identified on both ultrasound and magnetic resonance imaging were unchanged (8.33 percent), whereas at T12 those cytosteatonecrotic areas were increased on ultrasound (12.5 percent) and even more on the magnetic resonance imaging scans (16.67 percent). The average resorption percentage of injected volume was 15.36 percent at T6 months and 28.23 percent at T12 months. CONCLUSIONS: Postlipofilling breast changes can be distinguished from malignant alterations by experienced radiologists and need not interfere with early cancer diagnosis if patients are checked regularly. Moreover, magnetic resonance imaging is very useful for breast volume assessments and for detecting possible changes during longitudinal study. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

An Unusual Case of Mammary Paget's Disease Diagnosed Using Dynamic Contrast-Enhanced MRI.

Mammary Paget's disease is a rare presentation of breast cancer. At clinical examination, it is characterized by skin lesions of the nipple-areola complex, almost always a sign of malignancy. In fact, it is often associated with an underlying mammary ductal carcinoma in situ (DCIS) or invasive carcinoma. An underlying carcinoma is also common in women with negative mammography and ultrasound (US); in these cases, magnetic resonance imaging (MRI) is a diagnostic tool useful in the detection of occult cancer. We described an unusual case of mammary Paget's disease with underlying DCIS, in a patient without nipple-areola complex alterations and/or palpable lump. On suspicion of Paget's disease, the patient underwent MRI examination that proved useful for an accurate diagnosis. Biopsy confirmed dynamic MRI findings.

[The representation of Italian psychiatry in Italian Treccani Encyclopedia in 1930's]. / La rappresentazione della psichiatria Italiana nella Enciclopedia Italiana Treccani degli anni Trenta.

The article reconstruct the situation of Italian psychiatry around 1930, using as unusual sources the pages of the Enciclopedia Italiana di Scienze, Lettere e Arti. This important work, conceived in 1925 and finished in 1937, is due - as well known - to the strong interest of Giovanni Gentile and to his capacity to involve in the project a great part of Italian intellectual world, without any ideological preclusion. The section devoted to Medical Sciences, including Psychiatry, was directed by Nicola Pende (1880-1970) and Giacinto Viola (1870-1943). A prevalent positivistic approach to science is well testified by their specific attention to preventive and social medicine, researches in Genetics and in biotypological constitutions. Psycopathological and psycological lemmas are very limited, underlying the medical disinterest towards contemporary philosophy and psycology.

[Internet addiction disorder and social networks: statistical analysis of correlation and study of the association with social interaction anxiousness]. / Internet addiction disorder e social network: analisi statistica di correlazione e studio dell'associazione con l'ansia da interazione sociale.

INTRODUCTION: Internet Addiction Disorder (IAD) is an emerging psychiatric disorder, assimilable to impulse control problems and related to maladaptive use of new networks and social and virtual technologies. AIM: Our study aims to analyze the presence of IAD among adolescents and to study the correlation with social interaction anxiousness. We investigated also the possibility that the Social Network (SN) represent a source of risk for the development of IAD. MATERIALS AND METHODS: The test group was composed of 250 subjects, aged between 14 and 18 years. They were administered: Young's IAT; IAS (Interaction Anxiousness Scale), AAS (Audience Anxiousness Scale) and SISST (Social Interaction Self-Statement Test) to analyze the dimension of social interaction anxiousness. RESULTS: We found a rate of 2% of the IAD. The SN are the most common use of the Net in our sample, but not the most clicked sites by subjects with IAD. It should be noted, finally, a correlation between social interaction anxiety and IAD, but not a significant difference in scores of social anxiousness scales based on the SN use/non-use. CONCLUSIONS: The use of SN intended as single variable doesn't correlate with increased risk for IAD, or for increased social interaction anxiousness. However, if associated with prolonged use of the net for 5-6 hours or more, or concomitant use of chat rooms and/or net gambling, we find a more significant risk of psychopathology. The data presented require further investigations, in order to guide new pathogenetic models and appropriate intervention strategies.

[Motivation in brief psychotherapy: a 30 patients study, valued in a psychiatric day-hospital]. / Motivazione al trattamento con psicoterapia breve: studio condotto su 30 casi valutati nel day hospital psichiatrico.

INTRODUCTION: The most important predictive factor for a successful outcome in Brief Psychotherapy is the motivation of patients to the treatment itself. Against the scarcity of literature on the subject, so far limited to offer standardized tools to assess motivation, applied mainly to education and work's areas, in spite of a possible application in psychotherapy, it was considered necessary to develop a questionnaire ad hoc. MATERIALS AND METHODS: It was therefore created a pattern of motivational diagnosis of the problem based on a sequence of questions and answers, which would make possible the classification of each case and then that could lead to the use of a specific method. It is the result of the attempt to create an orderly pattern and that it would be easy to use and then be analyzed. The questionnaire consists of twenty one questions and requires that the patient answers with a "yes" or a "no" to each applicant. It was administered to thirty patients who came from the psychiatric day hospital. The questionnaire was used as a "not standardized thread" in which, through groups of questions, are addressed some central cores: the spontaneous activity, motivation controlled from the outside, motivation directed to an activity that leads to results, motivation to and activity for a purpose, expectations of self-efficacy, the presence/absence of resistance and finally the area of the will. The purpose of this work is to show, bringing a contribution in agreement with the few studies on the subject, how motivation is a key parameter for predicting the effectiveness of a psychotherapy, in this case, Brief Psychotherapy. CONCLUSIONS: The study clearly shows how the motivation is the most important positive predictor in the preliminary assessment of a Brief Psychotherapy: results in treatment are most likely to be rapid and favorable if patients are motivated to change andif they are engaged with the therapist.

Brain hemodynamic changes associated with chronic cerebrospinal venous insufficiency are not specific to multiple sclerosis and do not increase its severity.

PURPOSE: To investigate the relationship between chronic cerebrospinal venous insufficiency (CCSVI) and cerebral hemodynamic parameters and to disclose any possible involvement in the pathophysiology of multiple sclerosis (MS). MATERIALS AND METHODS: The study was approved by the institutional review board, and written informed consent was obtained from all participants. The diagnosis of CCSVI was assigned by using specific color Doppler ultrasonographic criteria. Cerebral blood volume (CBV), cerebral blood flow (CBF), and mean transit time were assessed with dynamic susceptibility contrast material-enhanced magnetic resonance imaging in normal-appearing white matter (NAWM) in 39 patients with MS. Of these, 25 had CCSVI and 14 did not. Twenty-six healthy control subjects were also evaluated, and of these, 14 had CCSVI and 12 did not. Two-way analysis of variance testing was used for statistical analysis, with Bonferroni correction for multiple comparisons. Correlation analysis was performed by calculating Spearman coefficients. RESULTS: Individuals with CCSVI showed cerebral hemodynamic anomalies, such as decreased CBF and CBV, as compared with individuals without CCSVI, without any delay in mean transit time. No significant interaction between MS and CCSVI was found for any hemodynamic parameters. Furthermore, no correlations were found between CBV and CBF values in NAWM or for severity of disability in patients with MS. The MS group showed prolonged mean transit time in the periventricular NAWM, as compared with the control group, and positive correlation was found between mean transit time values and disability scales in patients with MS. CONCLUSION: The data support a role of CCSVI in cerebral hemodynamic changes, such as a decrease of CBV and CBF, regardless of the presence of MS. CCSVI had no effect on neurologic function and disability progression in patients with MS.

Differences between proximal versus distal intraorbital optic nerve diffusion tensor magnetic resonance imaging properties in glaucoma patients.

PURPOSE: To analyze in vivo the diffusion tensor magnetic resonance imaging (DT-MRI) properties of the intraorbital optic nerve at two different levels: Proximal to the optic nerve head (ONH) and distal to the ONH at the level of the orbital apex in glaucoma patients. METHODS: Twenty-four patients with primary open-angle glaucoma were examined. The categorization into early and severe glaucoma was performed by Hodapp's classification. Fifteen healthy individuals served as controls. DT-MRI was performed with a 3T-MR unit. RESULTS: At early stage mean diffusivity (MD) values were higher at the proximal site with respect to the distal site. On the contrary, a decrease in fractional anisotropy (FA) was observed only relative to patient stage, independent of optic nerve site. Moreover, at early disease stage an increase in overall diffusivities, was evident at the proximal site, whereas at the distal site a decrease of the largest diffusivity and an increase in both the intermediate and smallest diffusivities were observed. FA and MD measured at the proximal site, had, respectively, the highest sensitivity and specificity in discriminating between healthy and glaucomatous eyes. CONCLUSIONS: Our study represents the first attempt to evaluate in vivo fiber integrity changes along the optic nerve with DT-MRI. Optic nerve degeneration appears to be a process that affects differently the proximal and the distal segments of the optic nerve. The complementary high sensitivity of FA with the high specificity of MD at the proximal site may provide reliable indexes for the identification of glaucomatous patients at early stages.

A Rectourethral Fistula due to Transrectal High-Intensity Focused Ultrasound Treatment: Diagnosis and Management.

Colovesical fistula (CVF) is an abnormal connection between the enteric and the urinary systems. The rectourethral fistula (RUF) is a possible but extremely rare complication of treatment of prostate cancer with "transrectal High-Intensity Focused Ultrasound (HIFU) treatment." We present a case of CVF due to HIFU treatment of recurrent prostate cancer. The case was assessed with cystography completed with a pelvic CT scan-with MPR, MIP, and VR reconstruction-before emptying the bladder. Since the CT scan confirmed that the fistula involved solely the urethra and excluded even a minimal involvement of the bladder, it was possible to employ a conservative treatment by positioning a Foley catheter of monthly duration, in order to allow the urethra to rest. Still today, after 6 months, the patient is in a good clinical condition and has not shown yet signs of a recurrence of the fistula.
