Association between functional recovery and medication adherence in schizophrenia.

AIM: Medication adherence is important for achieving functional recovery from schizophrenia and is commonly assessed using the Drug Attitude Inventory-30 (DAI-30). Subscales of the DAI-30, including "awareness of the need for medication," "awareness of the effects of psychiatric drugs," and "impression of medication," have been used to assess medication adherence. To determine which of these subscales are associated with the prognosis of schizophrenia, this study followed patients with schizophrenia to identify the prognosis and examine the subscales related to "recovery." METHODS: In total, 89 patients were recruited, 78 of whom were registered in the study. After assessing adherence using the DAI-30, Positive and Negative Syndrome Scale and Global Assessment of Functioning scores were assessed at 0 and 24 week to define the functional prognosis. RESULTS: At the end of the 24-week follow-up period, 36% of patients showed recovery from schizophrenia. A comparison of subscales revealed that the score for "impression of medication" was significantly higher in the recovery than in the non-recovery group. Logistic regression analysis identified only the "impression of medication" score as being predictive of recovery. CONCLUSION: The results indicated that among the three DAI-30 subscales, "impression of medication" was the most closely associated with recovery in patients with schizophrenia.

Associations between parental bonding during childhood and functional recovery in patients with schizophrenia.

INTRODUCTION: Schizophrenia is believed to be etiologically associated with environmental factors. Poor parental bonding, especially arising from "low care" and "overprotection," may contribute to the prognosis in patients with psychosis. In the present study, we investigated the associations between the aforementioned two different parental bonding types and the prognosis, in terms of the functional recovery, of patients with schizophrenia. METHODS: A total of 89 patients with schizophrenia were recruited, and 79 patients were registered for the study. After the parental bonding types and representative childhood adverse events were assessed, specific items on the PANSS were assessed at 0 and 24 weeks of the study period to define the functional prognosis. RESULTS: At the end of the 24-week follow-up period, 36% of the patients were judged as showing recovery from schizophrenia. The score for "overprotective attitude," but not that for "low care," was found to be significantly higher in the non-recovery (defined below) group. Exploratory logistic regression analysis identified only "overprotective attitude" of the parents as being predictive of non-recovery. Moreover, a significant negative correlation was found between "low care" and "overprotective attitude" only in the non-recovery group. CONCLUSION: In the present study, we showed that an overprotective attitude of the parents was associated with non-recovery in patients with schizophrenia.

Impact of FDG-PET findings on decisions regarding patient management strategies: a multicenter trial in patients with lung cancer and other types of cancer.

OBJECTIVE: To date, numerous studies have been conducted on the diagnostic capabilities of positron emission tomography using [(18)F]-fluorodeoxyglucose (FDG-PET). However, no studies designed to evaluate the influence of FDG-PET on the selection of patient management strategies within the Japanese healthcare system have been reported to date. The aim of the present study was to investigate prospectively the proportion of patients whose management strategies were modified based on FDG-PET findings (strategy modification rate). METHODS: The strategy modification rate was calculated by comparing the patient management strategy (test and treatment plans) after FDG-PET with the strategy before FDG-PET for 560 cancer patients with nine types of cancer (lung cancer, breast cancer, colorectal cancer, head/neck cancer, brain tumor, pancreas cancer, malignant lymphoma, cancer of unknown origin, and melanoma). In addition, the details of the modifications to the patient management strategies were analyzed. RESULTS: The strategy modification rate for patients with lung cancer was 71.6% (149 of 208 patients, 95% confidence interval 65.0-77.7%), which was higher than previously reported strategy modification rates for lung cancer before and after FDG-PET (25.6%). The strategy modification rates for patients with cancers other than lung cancer were as follows: breast, 44.4% (56/126); colorectal, 75.6% (62/82); head and neck, 65.2% (15/23); malignant lymphoma, 70.0% (35/50); pancreas, 85.0% (17/20); and cancer of unknown origin, 78.0% (32/41). The mean modification rate (major and minor modifications) of the treatment plans after FDG-PET, relative to the plans before FDG-PET, was 55.4% (range 44.0-69.2%), with major modifications pertaining to the treatment plan made in 43.3-68.2% of the patients based on the objectives of the FDG-PET examination. CONCLUSIONS: The results from this study indicate that FDG-PET can contribute to the modification of management strategies (particularly treatment plans), especially for lung cancer patients but also for patients with other types of cancer.

Increased pituitary volume in subjects at risk for psychosis and patients with first-episode schizophrenia.

AIM: Enlarged pituitary gland has been reported in schizophrenia, possibly reflecting hypothalamic-pituitary-adrenal hyperactivity. The aim of the present study was to examine whether individuals at risk of psychosis also have similar changes. METHODS: Magnetic resonance imaging was used to examine the pituitary volume in 22 individuals with at-risk mental state (ARMS; 11 male, 11 female), 64 first-episode patients with schizophrenia (FESz; 37 male, 27 female), and 86 healthy controls. The control subjects were divided into age- and gender-matched controls for ARMS (11 male, 11 female) and FESz (37 male, 27 female). RESULTS: Both the ARMS and FESz groups had a larger pituitary volume compared with matched controls, but no difference was found between the ARMS and FESz subjects. There was no association between the pituitary volume and clinical variables (symptommeasures at scanning, daily dosage or duration of antipsychotic medication) in either clinical group. The pituitary volume did not differ significantly between the ARMS individuals who later developed schizophrenia (n = 5) and those who did not (n = 17). The pituitary volume was larger in women than in men for all diagnostic groups. CONCLUSION: The finding of increased pituitary volume in both ARMS and FESz subjects may reflect a common vulnerability to stress in early psychosis. Further work in a larger ARMS sample is required to examine the possible relationship between pituitary volume and emergence of psychosis.

Longitudinal MRI study of the midline brain regions in first-episode schizophrenia.

This magnetic resonance imaging (MRI) study investigated the prevalence and size of the adhesio interthalamica (AI) and cavum septi pellucidi (CSP) in 64 first-episode schizophrenia patients and 64 controls, of whom longitudinal data were available for 20 patients and 21 controls. The AI was shorter in the patients and showed longitudinal decline in both groups; there was also a trend for AI atrophy to correlate with negative symptoms. The CSP showed no group difference. These results suggest a role for the AI as a possible neurodevelopmental marker of schizophrenia.

Gray matter changes in subjects at high risk for developing psychosis and first-episode schizophrenia: a voxel-based structural MRI study.

OBJECTIVES: The aim of the present study was to use a voxel-based magnetic resonance imaging method to investigate the neuroanatomical characteristics in subjects at high risk of developing psychosis compared with those of healthy controls and first-episode schizophrenia patients. METHODS: This study included 14 subjects with at-risk mental state (ARMS), 34 patients with first-episode schizophrenia, and 51 healthy controls. We used voxel-based morphometry with the Diffeomorphic Anatomical Registration through Exponentiated Lie Algebra tools to investigate the whole-brain difference in gray matter volume among the three groups. RESULTS: Compared with the healthy controls, the schizophrenia patients showed significant gray matter reduction in the left anterior cingulate gyrus. There was no significant difference in the gray matter volume between the ARMS and other groups. CONCLUSION: The present study suggests that alteration of the anterior cingulate gyrus may be associated with development of frank psychosis. Further studies with a larger ARMS subjects would be required to examine the potential role of neuroimaging methods in the prediction of future transition into psychosis.

Which Stress Does Influence Returning to Work in Japan, Inside or Outside the Workplace?

BACKGROUND: In this cohort study, we investigated the background factors promoting and inhibiting a return to work after long-term absence from work due to sickness among psychiatric outpatients. METHODS: We surveyed 73 psychiatric outpatients who were absent from work for a long time (POAWs), and 42 POAWs who were followed up until the 2-year time point. GHQ-30, NEO-FFI, MPS, RSS and questionnaires in-quiring about background factors, including relationships with others, were used, and the data were compared those who had returned to the work by the 2-year time point with those who had not. RESULTS: Factors promoting a return to work were "extroversion (NEO-FFI)", "organization (MPS)", and "neuroticism (NEO-FFI)", whereas "concern over mistakes (MPS)" was an inhibitory factor. Period of absence from work was markedly associated with psychological stress outside the workplace, while depression, anxiety, and even psychological stress inside the workplace were not. CONCLUSIONS: POAWs left from work by the result of psychiatric problems like depression, anxiety and so on. These were the result of their background factors, their characteristics, and psychological stress in/outside the workplace. After two-year psychiatric treatment, their psychological stress outside the workplace remained as an essential matter. These were inescapable because they were set in private place, while stress at the workplace could be left at the workplace.

Altered depth of the olfactory sulcus in first-episode schizophrenia.

A shallow olfactory sulcus has been reported in chronic schizophrenia, possibly reflecting abnormal forebrain development during early gestation. However, it remains unclear whether this abnormality exists at the early illness stage and/or develops progressively over the course of the illness. This magnetic resonance imaging (MRI) study investigated the length and depth of the olfactory sulcus in 64 first-episode schizophrenia patients and 64 controls, of whom longitudinal MRI data (mean inter-scan interval=2.6 years) were available for 20 patients and 21 controls. In the cross-sectional comparison at the baseline, the schizophrenia patients had a significantly shallower olfactory sulcus compared with the controls bilaterally, but there was no group difference in its anterior-posterior length. A longitudinal comparison demonstrated that the sulcus length and depth did not change over time in either group. The olfactory sulcus measures of the patients did not significantly correlate with clinical variables such as onset age, medication or symptom severity. These findings suggest that the olfactory sulcus depth, but not length, may be a static vulnerability marker of schizophrenia that reflects early neurodevelopmental abnormality.

Response to intra-arterial cisplatin and concurrent radiotherapy in a patient with primary mucosal malignant melanoma of the nasal cavity.

BACKGROUND: The prognosis for patients with mucosal malignant melanoma (MMM) of the nasal cavity is very poor because of the radioresistance of melanoma cells. METHODS: We present the first case report of the efficacy of superselective intra-arterial cisplatin (CDDP) infusion concurrent with hypofractionated radiotherapy (RT) for MMM of the nasal cavity. RESULTS: A pink, polypoid mass, histopathologically diagnosed as an amelanostic melanoma, occupied the right nasal cavity. After the treatment, a nasal tumor disappeared, leaving only a small bulge in the medial wall of the middle turbinate. Histopathologic examination revealed scattered degenerated melanoma cells, remaining only in the small restricted area in the medial surface of the excised middle turbinate. Twelve months after the treatment, the patient has not experienced any local recurrence or regional and distant metastasis. CONCLUSIONS: The superselective intra-arterial CDDP infusion concurrent with hypofractionated RT might be useful for the management of nasal MMM.

Reduced white matter fractional anisotropy and clinical symptoms in schizophrenia: a voxel-based diffusion tensor imaging study.

Although not consistently replicated, diffusion tensor imaging (DTI) studies in schizophrenia have revealed lower fractional anisotropy (FA) in various white matter regions, a finding consistent with the disruption of white matter integrity. In this study, we used voxel-based DTI to investigate possible whole-brain differences in the white matter FA values between 58 schizophrenia patients and 58 healthy controls. We also explored the association between FA values and clinical symptoms in schizophrenia. Compared with the controls, the schizophrenia patients showed significant FA reductions in bilateral superior longitudinal fasciculus, bilateral inferior fronto-occipital fasciculus, and genu of right internal capsule. Furthermore, in the patient group, the FA value of the anterior part of the corpus callosum was negatively correlated with the avolition score on the Scale for the Assessment of Negative Symptoms. These findings suggest widespread disruption of white matter integrity in schizophrenia, which could partly explain the severity of negative symptomatology.

Longitudinal MRI study of the pituitary volume in chronic schizophrenia: a preliminary report.

This longitudinal MRI study investigated the pituitary volume in 17 patients with chronic schizophrenia and 17 matched controls. In contrast to previous findings of pituitary expansion during the first episode of schizophrenia, the chronic patients showed non-significant mild pituitary atrophy, suggesting that the pituitary volume changes differently at different illness stages.

An essential dose of cisplatin for super-selective intra-arterial infusion concomitant with radiotherapy in patient with maxillary squamous cell carcinoma.

The present study investigated the efficacy and safety of using a lower dose of cisplatin (CDDP) in super-selective intra-arterial concurrent chemoradiotherapy (SSIACRT) to treat maxillary squamous cell carcinoma. 10 patients with maxillary squamous cell carcinoma (T3 n = 6, T4a n = 4) without regional or distant metastasis were treated by SSIACRT. The CDDP dose per course was 100 mg/body, i.e. 50-80 mg/m(2). 6-9 weeks after SSIACRT, partial maxillectomy was performed on all patients. Clinical and histological responses, survival rates, and adverse events were investigated. 10 (100%) of 10 patients achieved both clinical and pathological complete or partial remission. The 3-year overall and disease-free survival rates were 100 and 90%, respectively. Grade 3 toxicity was experienced by two patients. In conclusion, the SSIACRT regimen with a lower dose of CDDP (100 mg/body) had an equivalent therapeutic outcome and lower toxic outcome compared to a higher dose of CDDP. This regimen could be an effective and safe therapeutic modality for maxillary squamous cell carcinoma except T4b and N1/2 disease.

Respiratory involvement in IgG4-related Mikulicz's disease.

'Immunoglobulin G4 (IgG4)-related disease' is a new clinical concept of multi-organ diseases, with Mikulicz's disease (MD) being a clinical phenotype of IgG4-related disease. To clarify the clinical characteristics of respiratory involvement associated with IgG4-related MD, we retrospectively assessed 25 patients with MD, 11 (44%) of whom had allergic symptoms, and 7 (28%) of whom complained of respiratory problems. Thirteen patients (52%) presented with pulmonary and/or mediastinal lesions (P-MD) on chest computed tomography (CT), and 11 (44%) had lesions limited to the lacrimal and/or salivary glands (L-MD). Mean serum total protein, IgG, and IgG4 concentrations were significantly higher and CH50 was significantly lower in the P-MD than in the L-MD group. Immune complex was present only in the P-MD group. Chest CT images showed bronchial wall thickening, consolidation, nodule(s), interlobular thickening, ground glass opacity, pleural thickening/effusion, and mediastinal lymphadenopathy. Five of seven patients who underwent histological examination of the lungs had abundant IgG4-positive plasma cell infiltrates (IgG4/IgG-positive plasma cells >40%), but the other two did not. These findings suggest that respiratory lesions are not rare in patients with IgG4-related MD, and that they present with various manifestations. IgG4-related MD should be differentiated from similar diseases, such as sarcoidosis, bronchial asthma, Sjögren's syndrome, and malignant lymphoma.

A follow-up MRI study of the fusiform gyrus and middle and inferior temporal gyri in schizophrenia spectrum.

While longitudinal magnetic resonance imaging (MRI) studies have demonstrated progressive gray matter reduction of the superior temporal gyrus (STG) during the early phases of schizophrenia, it remains largely unknown whether other temporal lobe structures also exhibit similar progressive changes and whether these changes, if present, are specific to schizophrenia among the spectrum disorders. In this longitudinal MRI study, the gray matter volumes of the fusiform, middle temporal, and inferior temporal gyri were measured at baseline and follow-up scans (mean inter-scan interval=2.7 years) in 18 patients with first-episode schizophrenia, 13 patients with schizotypal disorder, and 20 healthy controls. Both schizophrenia and schizotypal patients had a smaller fusiform gyrus than controls bilaterally at both time points, whereas no group difference was found in the middle and inferior temporal gyri. In the longitudinal comparison, the schizophrenia patients showed significant fusiform gyrus reduction (left, -2.6%/year; right, -2.3%/year) compared with schizotypal patients (left: -0.4%/year; right: -0.2%/year) and controls (left: 0.1%/year; right: 0.0%/year). However, the middle and inferior temporal gyri did not exhibit significant progressive gray matter change in all diagnostic groups. In the schizophrenia patients, a higher cumulative dose of antipsychotics during follow-up was significantly correlated with less severe gray matter reduction in the left fusiform gyrus. The annual gray matter loss of the fusiform gyrus did not correlate with that of the STG previously reported in the same subjects. Our findings suggest regional specificity of the progressive gray matter reduction in the temporal lobe structures, which might be specific to overt schizophrenia within the schizophrenia spectrum.

Flow-sensitive alternating inversion recovery (fair) imaging for retrograde cortical venous drainage related to intracranial dural arteriovenous fistula.

INTRODUCTION: To evaluate the hypothesis that flow-sensitive alternating inversion recovery (FAIR) magnetic resonance (MR) imaging can detect retrograde cortical venous drainage (RCVD) in patients with intracranial dural arteriovenous fistula (DAVF). METHODS: Seven patients with angiographically confirmed DAVF with RCVD and two DAVF patients without RCVD underwent examinations with conventional MR imaging and FAIR, five of these seven patients with RCVD also underwent examination with dynamic susceptibility contrast (DSC) MR imaging. The ability of FAIR to depict prominent cerebral veins was evaluated, and FAIR was compared with the relative cerebral blood volume (rCBV) maps created with DSC. RESULTS: In all DAVF patients with RCVD, FAIR clearly showed prominent veins on the surface of the brain in affected hemisphere, and FAIR corresponded well with the areas of increased rCBV. In all DAVF patients without RCVD, FAIR showed no prominent veins. CONCLUSION: FAIR can detect RCVD in patients with DAVF.

Longitudinal volume changes of the pituitary gland in patients with schizotypal disorder and first-episode schizophrenia.

An enlarged volume of the pituitary gland has been reported in the schizophrenia spectrum, possibly reflecting the hypothalamic-pituitary-adrenal (HPA) hyperactivity. However, it remains largely unknown whether the pituitary size longitudinally changes in the course of the spectrum disorders. In the present study, longitudinal magnetic resonance imaging (MRI) data were obtained from 18 patients with first-episode schizophrenia, 13 patients with schizotypal disorder, and 20 healthy controls. The pituitary volume was measured at baseline and follow-up (mean, 2.7 years) scans and was compared across groups. The pituitary volume was larger in the schizophrenia patients than controls at baseline, and both patient groups had significantly larger pituitary volume than controls at follow-up. In a longitudinal comparison, both schizophrenia (3.6%/year) and schizotypal (2.7%/year) patients showed significant pituitary enlargement compared with controls (-1.8%/year). In the schizophrenia patients, greater pituitary enlargement over time was associated with less improvement of delusions and higher scores for thought disorders at the follow-up. These findings suggest that the pituitary gland exhibits ongoing volume changes during the early course of the schizophrenia spectrum as a possible marker of state-related impairments.

A follow-up MRI study of the superior temporal subregions in schizotypal disorder and first-episode schizophrenia.

While longitudinal magnetic resonance imaging (MRI) studies have demonstrated progressive gray matter reduction of the superior temporal gyrus (STG) during the early phases of schizophrenia, it remains unknown whether patients with schizotypal features exhibit similar STG changes. In this study, longitudinal MRI data were obtained from 18 patients with first-episode schizophrenia, 13 patients with schizotypal disorder, and 20 healthy controls. The volumes of the STG and its subregions [planum polare (PP), Heschl gyrus (HG), planum temporale (PT), rostral STG, and caudal STG] were measured on baseline and follow-up (mean: 2.7 years) scans and were compared across groups. At the baseline, both the schizophrenia and schizotypal patients had smaller left PT and left caudal STG than the controls. In a longitudinal comparison, the schizophrenia patients showed significant gray matter reduction of the STG over time (left: -2.8%/year; right: -1.5%/year) compared with the schizotypal patients (left: -0.6%/year; right: -0.3%/year) and controls (left: 0.0%/year; right: -0.1%/year) without a prominent effect of subregion or type of antipsychotic (typical/atypical). In the schizophrenia patients, greater annual volume reductions of the left PP and right PT were correlated with less improvement of positive psychotic symptoms. A higher cumulative dose of antipsychotics during follow-up in schizophrenia was significantly correlated with less severe gray matter reductions in the left PT and bilateral caudal STG. Our findings suggest that the left posterior STG subregions are commonly reduced in diseases of the schizophrenia spectrum; whereas, schizophrenia patients exhibit further progressive STG changes associated with overt psychosis in the early years of the illness.

The Disrupted-in-Schizophrenia-1 Ser704Cys polymorphism and brain morphology in schizophrenia.

The Disrupted-in-Schizophrenia-1 (DISC1) polymorphism is a strong candidate for a schizophrenia-susceptibility gene as it is widely expressed in cortical and limbic regions, but the effect of its genotype variation on brain morphology in schizophrenia is not well known. This study examined the association between the DISC1 Ser704Cys polymorphism and volumetric measurements for a broad range of fronto-parietal, temporal, and limbic-paralimbic regions using magnetic resonance imaging in a Japanese sample of 33 schizophrenia patients and 29 healthy comparison subjects. The Cys carriers had significantly larger volumes of the medial superior frontal gyrus and short insular cortex than the Ser homozygotes only for healthy comparison subjects. The Cys carriers tended to have a smaller supramarginal gyrus than the Ser homozygotes in schizophrenia patients, but not in healthy comparison subjects. The right medial superior frontal gyrus volume was significantly correlated with daily dosage of antipsychotic medication in Ser homozygote schizophrenia patients. These different genotype effects of the DISC1 Ser704Cys polymorphism on the brain morphology in schizophrenia patients and healthy comparison subjects suggest that variation in the DISC1 gene might be, at least partly, involved in the neurobiology of schizophrenia. Our findings also suggest that the DISC1 genotype variation might have some relevance to the medication effect on brain morphology in schizophrenia.
