Neuropathic Pain Features in Patients with Bone Metastases.

AIMS: The results of previous randomised controlled trials suggest that radiation oncologists should consider the presence of neuropathic pain when they prescribe dose fractionations for painful bone metastases. Although validated screening tools for neuropathic pain features are currently available, the prevalence of such features among patients with painful bone metastases is still poorly understood. The purpose of this study was to estimate the prevalence of neuropathic pain features among patients who received palliative radiotherapy for painful bone metastases. MATERIALS AND METHODS: We conducted a cohort survey of consecutive patients who received palliative radiotherapy for painful bone metastases at St Luke's International Hospital between 2013 and 2014. Patients were prospectively assessed before radiotherapy using the validated screening questionnaire to identify neuropathic pain components in Japanese patients. Pain with neuropathic features was prospectively defined using the total score of the seven-item questionnaire and a cut-off score ≥9. The pain response was assessed 2 months after the start of radiotherapy according to the criteria defined by the International Bone Metastases Consensus Working Party. RESULTS: Eighty-seven patients were assessed. Twenty-four per cent of patients (95% confidence interval: 16-35%) were diagnosed as having pain with neuropathic features. On multivariate analysis, no significant correlations were seen between neuropathic pain features and patient characteristics. Sixty-four patients (74%) were assessable 2 months after the start of radiotherapy. Overall response rates were 59% (95% confidence interval: 33-82%) in patients with neuropathic features and 55% (95% confidence interval: 40-70%) in those without such features. CONCLUSIONS: A considerable proportion of the patients were proven to have bone pain with neuropathic features. Further investigations are warranted to validate symptom assessment tools in cooperation with pain distribution and image findings, and to clarify if the presence of neuropathic pain affects the response to palliative radiotherapy.

Dynamic MR imaging of splenic tumor.

Inflammatory pseudotumor and hemangioma of the spleen are rare benign tumors, and MRI findings of splenic diseases have been reported only rarely. We recently observed three patients with inflammatory pseudotumor and hemangioma of the spleen. Abdominal ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI) and angiography demonstrated within the enlarged spleen. MRI and dynamic MRI after administration of gadolinium DTPA provide the characterization of the splenic tumor.

Cavernous hemangioma of the adrenal gland: MRI appearance.

We describe a case of cavernous hemangioma of the adrenal gland in which MR imaging showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, and dynamic MR imaging using Gd-DTPA showed late and delayed enhancement, allowing definitive diagnosis.

[Effectiveness of thrice-weekly injection of romurutide for prophylaxis of leukocytopenia during radiation therapy].

The effectiveness of thrice-weekly injection of Romurutide for leukocytopenia due to radiation therapy was analyzed. Twenty-two patients were randomly divided into two groups. Ten of group A cases were injected 3 times per week 10 times (3 weeks) and 12 of group B cases were injected 5 times per week 10 times (2 weeks). White blood cell counts and neutrophil numbers in group A were almost the same as in group B at day-3 and day-8, and those in group A were more than in group B at day-15 and day-22, although there were no statistical significances. Lymphocyte percentages, monocyte percentages and platelet cell counts between groups showed no differences. Injections were stopped in 3 cases due to fever (2 in group A, 1 in group B). The effects were recognized in nineteen cases (excluding above 3 cases). The effect of this thrice-weekly injection method during the injection period was the same or more than with 5 injections/week, and the period of the former was 50% longer. The 3 weekly injection method is more effective for prophylaxis of leukocytopenia.

[Results of electron beam irradiation for tongue cancer].

One hundred and eighty three patients with squamous-cell carcinoma of the tongue were treated with electron beam irradiation at the Dept. of Radiology, Nihon University School of Medicine, from 1967 to 1988. We analyzed the therapeutic results of the investigation to find out indications of squamous-cell carcinoma of the tongue to see if it could be treated by intra-oral cone irradiation with electron beam (IOC). The patients were restaged, as follows: stage I, 38 cases: stage II, 64 cases: stage III, 58 cases: stage IV, 23 cases. There were 113 males and 70 females, ranging in age from 18 to 87 years old. IOC was applied for T 1 or smaller T 2 cases. External neck irradiation and IOC were combined for larger T 2, T 3 or T 4 cases. The two-year local-control rates for primary lesions with the present method were 85% for T 1, 73% for T 2, and 58% for T 3. There were no two-year local-control cases for T 4. Clinical feature of the tumor were classified into tumourous type, small ulcerating type, and large ulcerating type. The two-year local-control rates were as follows: 80% for tumorous types, 68% for small ulcerating types and 53% for large ulcerating types. Uneven fractionated irradiation was performed on 144 cases and even fractionated irradiation was performed on 39 cases. The two-year local-control rates were as follows: 68% for uneven fractionated irradiation cases, 61% for even fractionated irradiation. In T 2 and T 3 cases, the two-year local-control rates were as follows: 77%, 63% for uneven fractionated irradiation cases, 56%, 40% for even fractionated irradiation cases. The two-year local-control rates were increased by uneven fractionated irradiation for T 2, T 3 cases (P < 0.05). We analyzed the therapeutic results in details for T 3 cases. T 3 patients were classified into two categories according to tumor size (category 1: long axis X short axis > 1000mm2: category 2: long axis X short axis < or = 1000mm2). The two-year local-control rates were 48% for category 1, and 72% for category 2. T 3 patients were classified into two categories according to clinical feature of the tumor (tumors with ulcers and tumors without ulcers). The two-year local-control rates were 43% with ulcers, and 74% without ulcers. The actuarial five-year survival rates were 92% for stage I, 72% for stage II, 67% for stage III, and 12% for stage IV.(ABSTRACT TRUNCATED AT 400 WORDS)

[Effect of fluconazole on Aspergillus infection associated with chronic granulomatous disease].

Aspergillus infection is the most frequent fungal infection associated with chronic granulomatous disease (CGD), and often results in a life-threatening situation. This report describes the use of high-dose fluconazole, a new antifungal agent, for invasive Aspergillus infection in a patient with CGD. A 27-month-old boy was sent to our hospital because of unknown fever in October, 1988. He was then admitted for pneumonia and pleural effusion of the right lung in February, 1989. Treatment with antibiotics was ineffective, and cultures of throat and pleural fluid were negative. In May, 1989, Aspergillus fumigatus was cultured from a subcutaneous abscess at the point of pleural puncture. Therefore we speculated that Aspergillus might have been the cause of pneumonia. The patient was diagnosed as having CGD by NBT test. Treatment with miconazole, flucitocin and amphotericin-B syrup was ineffective. From July, 1989, he was given 100 mg/day fluconazole d.i.v., but the drug did not reach an effective serum concentration to combat Aspergillus. However, an effective concentration of fluconazole was reached at a dose of 250 mg/day, and the chest X-ray findings subsequently improved, despite occasional high fever and continued high CRP. In July, 1990, the route of fluconazole administration was changed from d.i.v. to p.o. at the same dose, resulting in a serum concentration of fluconazole higher than that achieved with d.i.v. treatment. Both the clinical and laboratory findings showed improvement thereafter. Therapy for Aspergillus infection associated with CGD was found to necessitate high doses of anti-fungal drugs over a long period, although treatment with previously employed anti-fungal drugs could not be continued due to their adverse side effects.(ABSTRACT TRUNCATED AT 250 WORDS)

[The effects of contrast media on the cardiac conducting system in coronary angiography].

Comparative study of ionic and nonionic contrast media was carried out to investigate the effects on the cardiac conducting system caused by sodium ion and osmolality in coronary angiography. We evaluated the effects on the cardiac conducting system by 5% Glucose (5% GL), 20% glucose (20% GL), saline (SL), Ioxaglate 320 (IOX, ionic low-osmolar contrast medium, ionic LOCM), Iopamidol 370 (IOP 370, non ionic low-osmolar contrast medium, nonionic LOM) and 60% Diatrizoate (DTA, high-osmolar contrast medium, HOCM). In 18 patients who underwent coronary angiography, the effects on the cardiac conducting system were investigated using P-P time, A-H time, H-V time, QTc, T-wave height from His bundle electrogram and surface electrocardiogram. Prolongations of P-P time, A-H time and QTc with 20% GL, DTA were significantly longer than with IOX, IOP 370, 5% GL, and SL (p less than 0.01). There was almost no difference among 5% GL, SL, IOX, and IOP 370 in both P-P and A-H times. Also, prolongations of QTc with IOX, IOP 370 were longer than with 5% GL and SL (p less than 0.01). H-V time was not significantly prolonged with all solutions. The change of T-wave height with IOX was significantly greater than with IOP 370 (p less than 0.01). The change of T-wave height with SL was significantly greater than with 5% GL and that of T-wave height with 60% DTA was significantly greater than with 20% GL (p less than 0.01). Prolongations of P-P time, A-H time, QTc and changes of T-wave height were correlated with osmolality (p less than 0.01). These observations suggested that main factor of the disturbances of the cardiac conducting system excluding change of T-wave height was high osmolality of solution. Sodium ion took little part in the disturbances, and the factor of T-wave height change was not only due to the osmolality but also due to the concentration of sodium ion. LOCM caused much less significant disturbances of the cardiac conducting system than HOCM. There was almost no difference between non-ionic LOCM and ionic LOCM excluding the change of T-wave height.

B-cell function in Kawasaki disease and the effect of high-dose gamma-globulin therapy.

We studied in vitro B-cell function in Kawasaki disease (KD). By plaque-forming assay, IgG-, IgA- and IgM-secreting cells in the first week of KD were markedly increased, and recovered to a normal level in the second week in many cases. Lymphocyte blast formation with Staphylococcus aureus Cowan I (SAC), a B-cell-specific mitogen, was suppressed in the acute phase, and recovered to a normal level in the convalescent phase. By flow cytometry, HLA-DR- and HLA-DQ-positive cells were increased in the acute phase of KD. CD3- and CD4-positive cells were also decreased. CD8-positive cells showed no significant change. In five patients, CD4-positive cells with HLA-DR positivity neither increased in the acute phase nor changed during the course of illness. From our results, it can be considered that pathogenic microorganisms or toxins activate B cells directly in KD without the association of T cells. We also studied the effect of high-dose gamma-globulin therapy on B-cell function in KD. However, the results indicated that this form of therapy had no significant effect on B-cell functions.

[Uneven fractionation irradiation].

To get the better therapeutic ratio with low LET radiation therapy alone, the improvement of the physical dose distribution and the mode of dose fractionation are required. Since 1972, uneven fractionation irradiation with electron beam has been used for head and neck tumors. The 2 year control rates for primary tongue cancer T1, T2 and T3 by this method were approximately comparable to that of the small source implantation. In the treatment results for the cervical lymph node metastasis, uneven fractionation technique is superior to conventional one. Furthermore, this results was reviewed by means of multivariate analysis.

Small bowel pseudo-obstruction in Kawasaki disease.

Between June 1977 and May 1986, 310 patients with Kawasaki disease were admitted to Shizuoka Children's Hospital. Among these patients, seven showed the symptoms of intestinal paralysis during the acute stage. We present three of these cases who showed typical intestinal pseudo-obstruction radiologically, and discuss the treatment of this type of intestinal involvement.

Scoring method for identifying patients with Kawasaki disease at high risk of coronary artery aneurysms.

The beneficial effect of immunoglobulin in preventing coronary artery aneurysms in patients with Kawasaki disease is recognized, but immunoglobulin should be selectively given to patients at high risk for coronary lesions. The present study was designed to present a scoring method to evaluate the severity of Kawasaki disease in terms of coronary artery disease based on clinical and early laboratory findings. Seventy-eight patients who were admitted at 4 to 7 days of illness and who had received aspirin alone during the acute febrile period were separated into 2 groups according to significant coronary artery involvement, and possible related factors to the discrimination of the 2 groups were studied using multivariate analysis. Age at onset, C-reactive protein and platelet count contributed significantly to the discrimination, and from these 3 items a simple scoring system was devised to predict patients at high risk for coronary lesions. Retrospective study using this scoring method indicated that significant coronary artery disease was more often seen in patients predicted to be at high risk treated with aspirin, while no patients who received immunoglobulin had coronary lesions of moderate or severe degree. Thus, the present scoring method provides simple but clinically useful criteria for predicting patients at high risk of coronary artery disease, and immunoglobulin therapy for selected patients may reduce the significant coronary artery complications of Kawasaki disease.

Inherited deficiency of the seventh component of complement associated with meningococcal meningitis: lack of serum bactericidal activity against Neisseria meningitidis in a girl with C7 deficiency and HLA studies of a C7-deficient Japanese family.

An 8-year-old girl with meningococcal meningitis lacked serum complement activity. The seventh component of complement (C7) could not be detected in her serum by either functional or immunochemical analysis. The levels of the other components were within the normal range. Her serum complement activity was restored by the addition of purified C7. Her fresh serum showed a total absence of bactericidal activity against Neisseria meningitidis, group Y, but her serum bactericidal activity was restored by the addition of purified C7. The restoration of her serum bactericidal activity was completely inhibited in the presence of Mg2+ EGTA. These findings suggest that restoration of the bactericidal activity of her serum against N. meningitidis might be mediated by the specific antibody against N. meningitidis and the reconstituted complement system in her serum. Heterozygous deficiency of C7 was found in 10 of her family members. Genetic studies showed that the mode of inheritance might be an autosomal codominant trait. No genetic linkage between deficiency of C7 and the HLA system was found.

Computed tomography in postinfluenzal encephalitis.

A 2-year-old girl developed encephalitis following influenza A virus infection. Brain computed tomography (CT) showed symmetrical hypodense areas in the putamina. Contrast enhancement was noted surrounding the hypodense areas 2 days after the onset of encephalitis. These localized lesions demonstrated on CT have not been reported in the literature of postinfluenzal encephalitis.
