Symptom dimensions and needs of care among patients with schizophrenia in hospital and the community

The purpose of the present paper was to examine the psychiatric symptom dimensions related to needs of care among patients with schizophrenia in hospital and in the community. Subjects were 217 patients with F2 ICD-10 diagnoses. Hospital patients included 102 inpatients (47.0%) in psychiatric long-term care units. Community patients included 115 outpatients (53.0%) living in their homes or residential facilities. Psychiatrists used the Brief Psychiatric Rating Scale (BPRS) to assess patients' psychiatric symptoms. Formal care providers assessed needs of care using a scale developed by the Committee on Case Management Guidelines for People with Mental Disabilities in Japan. Instrumental Activities of Daily Living (IADL) self-performance and difficulty were also measured using a scale from the Minimum Data Set-Home Care (MDS-HC). Multiple regression analyses were applied, using the symptom dimensions as dependent variables and needs of care as independent variables. Patient group (hospital or community) was also used as an independent variable. Hospital patients demonstrated more severe psychiatric symptoms and greater needs of care than community patients. Multiple regression analyses showed that the total needs of care were greater among male patients (B = 0.142, P = 0.005), hospital patients (B = 0.310, P < 0.001), patients with poor IADL self-performance (B = 0.217, P = 0.047), and patients with severe negative symptoms (B = 0.240, P = 0.002; R(2) = 0.515). The present results suggested an association between negative symptoms and needs of care in schizophrenia. Hospital patients had greater needs of care, even though their psychiatric symptoms were controlled for. Further research should examine the relationships between psychiatric symptoms and needs of care in a cohort study following patients when hospitalized and when living in the community.     

Short-term wear of Japanese highly cross-linked polyethylene in cementless THA

INTRODUCTION: Production of polyethylene wear from acetabular liners is thought, in part, to mediate the periprosthetic osteolysis. This study examined the in vivo wear performance of Japanese highly cross-linked polyethylene (Aeonian) in cementless total hip arthroplasty. MATHERIALS AND METHODS: Ninety-five hips received a highly cross-linked polyethylene liner, while 20 hips were implanted with conventional polyethylene. Two-dimensional linear wear was measured on radiographs and volumetric wear was then calculated. Both linear and volumetric wear rates were examined for the 1-year postoperative period as well as for the time frame beginning after 1 year ending with the final follow-up. RESULTS: The amount of linear wear was significantly lower in the cross-linked group at 3 and 5 years postoperatively (P < 0.01 and < 0.001, respectively). Linear and volumetric wear rates after 1 year postoperatively for hips with the cross-linked polyethylene were significantly reduced by 57 and 59%, respectively, when compared to rates for those who received conventional polyethylene (P < 0.01). A multiple logistic regression analysis revealed that cross-linking was a significant factor influencing linear wear rate after 1 year postoperatively with an odds ratio, exp(ss) = 10.033 (P < 0.001). CONCLUSION: These results suggest that the highly cross-linked polyethylene reduces penetration of the femoral head and may be an optimal bearing surface for patients receiving total hip arthroplasty.     

Postoperative enteroenteric intussusception in patients with Crohn’s disease: Report of two cases

Postoperative enteroenteric intussusception is a rare complication in adult patients with Crohn’s disease. We treated two patients with Crohn’s disease accompanied by an ileal obstruction, each of whom underwent an elective resection. In both, the upper left quadrant of the abdoment became progressively distended following ileocecal resection and each required surgical treatment after diagnosis of postoperative enteroenteric intussusception by abdominal computed tomography scanning, as the intussusception could not be reduced by conservative treatment. There were no Crohn’s lesions found in the intussuscepted specimens, and the condition was thought to have been caused by a segment of thickened and fibrotic intestine that had developed because of long-standing bowel dilatation from obstructive Crohn’s lesions. In one of the patients, the intussusceptum was irreducibly incarcerated and required a resection, whereas it was able to be manually reduced in the other.     

Primitive reflexes distinguish vascular parkinsonism from Parkinson's disease

OBJECTIVES: Although vascular parkinsonism (VP) occurs frequently in the elderly, its clinical features have not been investigated in detail, particularly in comparison with Parkinson's disease (PD). The goal of this study is to clarify the diagnostic value of pathological reflexes in differentiating between VP and PD. PATIENTS AND METHODS: In 132 patients with PD and 55 with VP, pathological reflexes, including snout reflex (SR), palmomental reflex (PMR), corneomandibular reflex (CMR), jaw reflex (JR), Hoffmann reflex (HR), and extensor plantar response (EPR), were evaluated. RESULTS: The percentage of each pathological reflex elicited in two groups (VP:PD) was as follows: SR (78:30), PMR (53:26), CMR (9:6), JR (33:12), HR (29:11), and EPR (25:8). The prevalence of pathological reflexes, except for CMR, was significantly higher in the VP patients than in the PD patients. In particular, SR and PMR were more frequent than upper motor neuron signs in the VP patients. The sensitivity and specificity of either SR or PMR for VP were 84% and 82%. CONCLUSION: Snout and palmomental reflexes are useful tools in the differentiation between VP and PD.     

Diagnosis of adrenocortical tumor in a neonate by detection of elevated blood 17-hydroxyprogesterone measured as a routine neonatal screening for congenital adrenal hyperplasia: a case report

We report herein a case of prenatally detected neonatal adrenocortical tumor (ACT). The patient was an otherwise healthy newborn girl. No signs of Beckwith-Wiedemann syndrome were identified, and her family medical history did not suggest predisposition to cancer. Computed tomography and ultrasonography after birth revealed a round solid tumor 40 mm in diameter in the right suprarenal area. The precise diagnosis of ACT was unexpectedly obtained based on results from the Japanese neonatal mass screening program. Blood 17-hydroxyprogesterone is routinely measured as a part of this program for early detection of congenital adrenal hyperplasia in Japan. Abnormally elevated level of 17-hydroxyprogesterone was reported in the patient and, thus, led to the diagnosis of ACT. Surgical resection was safely performed with perioperative steroid replacement. Adrenocortical tumors are extremely rare in childhood, particularly in the neonatal period. Some of these tumors secrete abnormally high levels of cortisol, suppressing function of the contralateral adrenal gland and, thus, leading to life-threatening postoperative adrenal insufficiency. Scheduled steroid replacement enables safe perioperative management in such cases. Adrenocortical tumor should always be considered among the differential diagnoses for neonatal suprarenal mass because precise diagnosis will enable the physician to develop appropriate treatment strategies.     

Measurement of the platelet retention rate in a column of collagen-coated beads is useful for the assessment of efficacy of antiplatelet therapy

Introduction

A simple, validated method to measure platelet function is unavailable for bedside use. Measurement of platelet retention rate using a column of collagen-coated beads and whole blood is a new, simple assay that reflects platelet aggregation. This study was aimed to examine the utility of this assay to assess efficacy of antiplatelet drug therapy.

Methods

Citrated whole blood (1.5 ml) in a syringe was passed through a polyvinyl tube packed with collagen-coated beads for 40 seconds using a syringe pump. Platelet retention rate in the column was calculated from platelet counts in blood before and after passage. An increase in the retention rate reflects an increase in platelet activity. This new platelet retention assay and the traditional optical aggregometry assay were performed in 331 patients with stable coronary artery disease (CAD).

Results

The retention rate was significantly reduced in patients taking dual antiplatelet therapy (aspirin plus clopidogrel or ticlopidine) compared with aspirin alone. There was a significant linear correlation between the platelet retention rate and platelet aggregability measured by the traditional method (r = 0.44, p < 0.001). In multivariate Cox proportional hazards analysis, higher platelet retention rate was an independent predictor of future cardiovascular events in patients on dual antiplatelet therapy (hazard ratio 3.9, 95% CI 1.6 to 9.5, p = 0.003).

Conclusions

Measurement of the platelet retention rate in a column of collagen-coated beads may be useful for monitoring the efficacy of antiplatelet drug therapy in patients with CAD.     

Results of the Tokyo Consensus Meeting Tokyo Guidelines

A systematic review of references conducted in the process of developing the Guidelines for the Management of Acute Cholangitis and Cholecystitis did not find many high-quality research reports. There were no criteria for diagnosis, severity assessment, or patient transfer, and no established principles of clinical practice guidelines for acute cholangitis and cholecystitis. In order to develop guidelines that would be useful in clinical practice, an understanding of the current status of clinical practice for acute cholangitis and cholecystitis was considered essential. After several open symposia and a survey of these two diseases, we developed and published a Japanese-language version of Evidence-Based Practice Guidelines for the Management of Acute Cholangitis and Cholecystitis. In order to prepare international Guidelines, we had repeated discussions about the draft Guidelines together with international experts, and, following the Consensus Meeting, held on April 1–2, 2006, in Tokyo, with the attendance of 300 world experts in the field, the International Guidelines for the Management of Acute Cholangitis and Cholecystitis were developed. In this article, we outline the comments and opinions given at the International Meeting and how they are reflected in the final version of the Guidelines.
