We conducted an additional analysis using the data from the post-marketing surveillance of Alglucosidase alfa for Pompe disease. We aimed to investigate the changes in the percentage of predicted forced vital capacity (%FVC) and the changes in the distance of the 6-min walk test (6MWT) by overall improvement and to investigate the %FVC change by the duration from symptom onset to survey registration (shorter/longer groups) using a linear mixed model. Thirty-seven and eighteen survey participants had %FVC and 6MWT data available, respectively; of the patients whose overall improvement was rated as "relatively improved," %FVC and 6MWT worsened in 71.4% and 66.7%, respectively. The %FVC at the survey registration estimated using a linear mixed model was significantly higher in the shorter group than in the longer group (P = 0.0413). The estimated slope of %FVC was significantly lower in the shorter group than in the longer group (P = 0.0051). These results suggest the importance of early treatment initiation and quantitative evaluation of each symptom.

Objective　This study aimed to investigate changes in attitudes toward suicide following a universal home visitation program that included a brief face-to-face educational session focusing on gatekeeper roles in Japan.Methods　Between 2015 and 2017, members of 169 households in an intervention district from a northern Japanese township were invited to attend an educational session during home visits. The participation rate was 72.8%, with 94.5% of the participants aged over 40. Repeated cross-sectional population-based surveys were conducted among adults in the towns in 2015 and 2021. Data from the surveys, focusing on individuals aged 40-79 years and residing in the intervention and matched control districts (where no visits occurred and only information was distributed through leaflets), were used to assess the prevalence of self-reported views toward suicide. The self-reported views encompassed "no substantial thoughts," "inevitable," "shameful," "annoying," "tragic," "must be managed," and "romantic" in addition to personal and perceived stigma, depressive symptoms (assessed using the Kessler Psychological Distress Scale-6), and suicidal ideation. Data were analyzed using generalized linear mixed models. The Cochran-Armitage test was used to analyze linear trends in the proportion of views that exhibited changes.Results　Participation rates were 61.8% (n ＝ 357) in 2015 and 52.8% (n ＝ 257) in 2021. The intervention group showed a significant difference in the prevalence of the "inevitable" view between baseline and 4-year follow-up (P ＝ 0.026). Marginal pre-post differences were observed among the two types of stigma; however, the symptoms remained unchanged. A marginally significant difference in the change of the "inevitable" view was observed between the two groups. In the follow-up, more knowledgeable respondents in the intervention group were less likely to view suicide as "inevitable," a trend not seen in the control group.Conclusions　The universal home visitation program, including a face-to-face session focusing on the gatekeeper role, was associated with a decreased prevalence of the "inevitable" attitude between the baseline and 4-year follow-up among community-dwelling adults aged 40-79. This suggests that face-to-face interactions with healthcare professionals can reduce the tendency to condone suicide among middle-aged and older adults in community settings.

Purpose: To predict side effects and optimize injection doses in the dosimetry of 177 Lu imaging, highly accurate quantitative SPECT images are required. Monte Carlo simulations were performed to verify the accuracy and variability of quantitative values for 177 Lu imaging under various imaging conditions., Methods: SPECT data of NEMA body phantom were assumed to simulate intrahepatic tumors 6 h after administration of 7.4 GBq of 177 Lu-Dotatate. SPECT data were acquired using the SIMIND program with different combinations of collimators and energy windows. For variability evaluation, 30 SPECT images with Poisson noise were generated for each acquisition time. The relative error was evaluated for accuracy evaluation, and the coefficient of variation was estimated for variability evaluation., Results: The accuracy of BG quantification was less than 10% relative error. The accuracy of hot sphere quantification was highest with the combination of MEGP and an energy window of 208 keV±10%. However, the accuracy of hot sphere quantification decreased significantly with decreasing hot sphere diameter. Variability varied with imaging conditions and improved with longer acquisition time., Conclusion: Monte Carlo simulations revealed the accuracy and variability of quantitative values for each SPECT imaging condition for 177 Lu imaging.

Purpose: During computed tomography pulmonary angiography (CTPA), a decrease in the CT value of the pulmonary artery may be observed due to poor contrast enhancement, even though the imaging is performed at the optimum timing while continuously injecting a contrast medium. This study focused on the increase in blood flow in the superior and inferior vena cava during inspiration that affects the decrease in the CT value of the pulmonary artery and investigated a radiography method in which a delay time was set after inspiration in clinical cases., Methods: A total of 50 patients who underwent CTPA for suspected pulmonary thromboembolism were included. Using the bolus tracking method, we monitored the pulmonary arteries before and after inspiration, and investigated the CT value changes., Results: A decrease in the CT value of the pulmonary artery after inspiration was observed in approximately 30% of cases. By setting the delay time, the contrast enhancement effect before and after inspiration became equivalent., Conclusion: As a result of this study, avoiding a decrease in the CT value of the pulmonary artery is possible by setting a delay time after inspiration, which is considered useful during CTPA.

In the case of oropharyngeal carcinoma, patients may present with symptoms similar to cervical lymphadenopathy, and the primary lesion may only be diagnosed after cervical mass extirpation/biopsy. We retrospectively analyzed the clinical course in 11 oropharyngeal carcinoma patients that were diagnosed after cervical mass extirpation/biopsy between 1998 and 2013. Before the diagnosis was made of oropharyngeal carcinoma, a cervical lymph node biopsy was performed in six patients; the lymph node was extirpated due to an initial diagnosis of lateral cervical cyst in four patients; and neck dissection was performed due to an initial diagnosis of primary unknown carcinoma in one patient. The primary tumor site in the oropharynx was the palatine tonsil in six patients and the lingual tonsil in five patients. Five of six patients with palatine tonsil carcinoma and three of five patients with lingual tonsil carcinoma were found to be positive for human papillomavirus (HPV). The duration from cervical lymph node extirpation/biopsy to final diagnosis was 1 to 13 months. All patients finally underwent radiation therapy or chemoradiotherapy, and they had no recurrence or metastasis. As the incidence of HPV-related oropharyngeal carcinoma increases, the number of oropharyngeal carcinomas assumed to be cervical lymphadenopathy due to the presenting symptoms may increase. It is important to investigate the oropharynx thoroughly so as to adequately differentiate the possibility of oropharyngeal carcinoma from that of cervical lymphadenopathy. Metastatic lymph nodes might present as cysts in cases of oropharyngeal carcinoma, it is therefore necessary to take the potential for metastatic lymph nodes in the oropharyngeal cancer into consideration when differentiating this disease from cervical cyst-shaped lesions.

Aim/methods: A series of 10 cases of chest wall tuberculosis (man/woman=7/3, average age 62 +/- 17 years old) during past seven years were reviewed., Results: Acid-fast bacillus was detected from an abscess in 60% by smear, 30% by culture, and 75% by polymerase chain reaction (PCR). It was characteristic that enhanced CT of abscess revealed a low density mass with peripheral enhancement, 'rim enhancement findings', in all cases. CT also showed ipsilateral pleural thickening in all cases, suggesting lymphogenous pathogenesis of chest wall lesions from tuberculous pleurisy. As for the treatment, antituberculosis chemotherapies were done in all cases. In addition, open drainage was done in 8 cases and curettage of abscess was performed in 5 cases. None of these ten cases had relapsed during the follow-up periods for 12 to 77 months., Conclusions: Chest wall tuberculosis is still important as a disorder of a chest wall mass requiring differential diagnosis. Contrasting CT is thought to be useful for the diagnosis. It should be emphasized that 50% of the cases had good outcome without curettage.

We treated a patient with recurrent ovarian cancer with cancerous peritonitis by weekly paclitaxel (w-TXL) therapy (65 mg/m2). Abdominocentesis was not performed to eliminate ascites, in order to maintain higher quality of life (QOL), and critical adverse reaction was not seen for 12 months. We measured the TXL concentration in blood plasma and ascites after TXL infusion by HPLC method. The TXL titer in plasma was 427 ng/ml after infusion, 23 ng/ml after 24 hours and under 10 ng/ml after 48 hours. The TXL titer in ascites was 41 ng/ml after infusion, 37 ng/ml after 6 hours, 18 ng/ml after 12 hours, 10 ng/ml after 24 hours and under 10 ng/ml after 48 hours. TXL transportation from blood to ascites was good. This result suggested that intravenous infusion of TXL was effective for cancerous peritonitis treatment.

It is well known that neuropathy, myelopathy, and arthropathy are specific adverse effects induced by paclitaxel administration. Parkinson's disease is neural degenerative disease, and the influence of paclitaxel administration on patients with Parkinson's disease is unknown. We have successfully treated an ovarian cancer patient with Parkinson's disease by paclitaxel/CBDCA combined chemotherapy after surgery. The patient was a 57-year-old woman with solid and cystic ovarian tumor. Among the tumor markers CA125, CA19-9, and SLX, only SLX was elevated. We operated and made a pathological diagnosis of the ovarian tumor as clear cell adenocarcinoma (FIGO stage Ic). After surgery, the patient was treated with paclitaxel (260 mg [175 mg/m2]) and CBDCA (600 mg [AUC = 5]) combined chemotherapy for 5 courses. Her status is complete remission. During chemotherapy, she had felt the decreased efficacy of her Parkinson's disease medication. We could continue chemotherapy by increasing the dose of the Parkinson's drug. There is only one case report on the influence of paclitaxel on Parkinson's disease, in which the course was similar to the present case.

Unlabelled: End-stage renal failure patients on chronic dialysis are high risk groups of tuberculosis due to attenuated cellular immunity. Patients receiving haemodialysis stay prolonged time inside the health-care facilities, thereby increased risk of tuberculosis transmission if a patient has active disease. So management of active pulmonary tuberculosis undergoing haemodialysis is important, however, the number of hospitals which are capable of taking care of such patients is estimated to be few in Japan., Methods: From August 1994 through July 2002, 1059 active pulmonary tuberculosis patients (mean age; 57 +/- 19, male/female = 773/286) were admitted to Nishi-Kobe Medical Center, a 500-bed teaching hospital. Out of them, patients undergoing haemodialysis were retrospectively studied to describe the clinical characteristics of such cases. Then we conducted a questionnaire survey regarding the management of active pulmonary tuberculosis patients undergoing haemodialysis for 86 self-governing bodies in Japan., Results: (1) Clinical characteristics of active pulmonary tuberculosis undergoing haemodialysis. We encountered 14 cases (mean age; 65 +/- 11, male/female = 7/7) of pulmonary tuberculosis undergoing haemodialysis during 8 years. In addition to pulmonary involvement, 3 pleural, one knee joint and one lymph node involvement was detected. Primary renal disease included diabetic nephropathy (n = 3), chronic glomerulonephritis (n = 3), congenital anomaly (n = 1), and unknown (n = 7). Nine cases were referred to our hospital from health-care facilities located out of city or prefecture. In five cases it took more than three months from the onset or detection of abnormal chest X-ray findings to the admission to our hospital. Five cases developed pulmonary tuberculosis within the first year after the initiation of dialysis. None of the patients had a past history of tuberculosis. Cavitary lesion on chest X-ray was observed in only one case. Triple antituberculosis therapy was used in 9 patients, and 4 antituberculosis drugs were used in 5 patients. Antituberculosis therapy was successfully done in all cases except two patients who died of apoplexy and cerebral infarction. (2) The nation-wide questionnaire survey. Of the 86 self-governing bodies we mailed, 66 self-governing bodies replied. Of them, 31% reported that they have experienced difficulties in the management of active pulmonary tuberculosis patients undergoing haemodialysis, and 25% reported the lack of health-care facilities to take care of such cases in their territory. They have referred such patients to hospitals located in the nearby prefectures or they have recommended antituberculosis therapy visiting a local haemodialysis facility., Conclusion: There are sometimes difficulties to manage active pulmonary tuberculosis patients undergoing haemodialysis in Japan. Health-care facilities to take care of such patients should be arranged and the formation of the network is necessarily.

Monitoring of cochlear function is one proposed clinical application of otoacoustic emission (OAE). To determine the clinical utility of OAE in monitoring, we studied changes in OAE during the glycerol test used to diagnose endolymphatic hydrops. Transiently evoked OAE (TEOAE) and distortion product OAE (DPOAE) were measured before and 3 hours after oral administration of glycerol in 22 ears of patients with Meniere's disease. The positive result in the glycerol test was observed in 11 of 22 ears. TEOAE was recorded using a nonlinear click stimulus, and total echo power (TEP) of the whole response and filtered echo power (FEP) of its mid-frequency (1000-2000 Hz) component were used as TEOAE parameters. The growth functions of DPOAE were recorded at 3 F2 frequencies--1000, 1500, and 2000 Hz. Changes in the growth function were determined based on changes in 2 parameters--maximum level and detection threshold of DPOAE. When changes in these 4 parameters exceeded 2 standard deviations above mean test-retest variability determined from OAE data for 17 normal ears, they were considered significant. Significant changes indicating improved cochlear function in 4 OAE parameters or the appearance of OAE during the glycerol test were judged positive for OAE. Regardless of glycerol test results, positive findings were observed in both OAEs whenever a pure-tone threshold at 1000 or 2000 Hz improved. However, even in ears for which pure-tone thresholds at these frequencies did not improve, both OAEs frequently exhibited positive findings. In all ears with a positive result in the glycerol test, positive findings were observed in DPOAE, but not in TEOAE. Of the 2 parameters of TEOAE, FEP always exhibited a positive finding in ears with a positive TEP finding and FEP positivity was higher than that of TEP. In DPOAE, no cases showed a positive finding only at F2 = 2000 Hz, and DPOAE at F2 = 1000 Hz could not be detected in 4 ears due to high noise floor. Overall, positive findings were obtained in 14 ears (63.9%) for TEOAE and 20 ears (90.9%) for DPOAE. In only 1 ear were no positive findings observed in either OAE. The sensitivity of OAE measurement as a diagnostic test for endolymphatic hydrops was higher than that of pure-tone audiometry. Of the 2 OAEs, test sensitivity was much higher for DPOAE than for TEOAE. These results show that OAE measurement detects changes in cochlear function during the glycerol test more sensitively than pure-tone audiometry. They also suggest that FEP is a better indicator than TEP as a parameter of TEOAE, and that DPOAE measurement at F2 = 1000 and 1500 Hz is sufficient for practical clinical use. However, of the 2 OAEs, DPOAE was considered more appropriate than TEOAE for monitoring during the glycerol test because of its high sensitivity in detection of changes in cochlear function. In conclusion, clinical use of OAE, especially DPOAE, as a test complementary to pure-tone audiometry during the glycerol test is very useful and will improve the diagnosis of endolymphatic hydrops.

A 64 years old woman without systemic immunological disorders was admitted to our hospital because of a productive cough, low grade fever and bloody sputum. Chest X-ray revealed multiple nodules with calcification, infiltrates and bronchiectasis. Laboratory findings showed mild hypoproteinemia and elevated sedimentation rate. Both Nocardia farcinica and Mycobacterium intracellulare were isolated from the bronchial lavage fluid. Administration of sulfamethoxazole-trimethoprim improved her symptoms. In a recurrent study of bronchial lavage N. farcinica was not isolated, but M. intracellurale was still isolated. We believe that N. farcinica may cause infectious exacerbation of chronic lung disease: non-tuberculous mycobacteriosis and bronchiectasis.

Bactericidal activities of an amphoteric surfactant (12 w/v% Alkyl diaminoethylglycine hydrochloride, 3 w/v% Alkyl dietylenetriaminoglycole hydrochloride, Nissan Anon #300, Inui Shouji Co., ADG) against Mycobacterium tuberculosis were examined independently or in cooperation with ethanol. The results obtained in the study are as follows: 1. In the treatment with the surfactant diluted with distilled water in one hundredth, the numbers of tubercle bacilli which survived were 500 cfu/0.1 ml after one minute-treatment, and 25 cfu/0.1 ml after ten minutes-treatment. On the other hand, the surfactant containing 23 v/v% ethanol decreased the bacterial numbers to seven cfu/0.1 ml after one minute and less than one cfu/0.1 ml after ten minutes. The numbers of the survived bacilli treated with the surfactant containing 20 v/v% ethanol were 500 cfu/0.1 ml after one minute-treatment, and less than one cfu/0.1 ml after ten minutes though 20 v/v% ethanol alone was ineffective in ten minutes-treatment. 2. The bactericidal activities of the surfactant against tubercle bacilli in sputum samples in which 1.65 x 10(4) cfu/0.1 ml of the organism were contained were also investigated. The numbers of tubercle bacilli which survived were 25 cfu/0.1 ml after one minute-treatment with the surfactant in one fiftieth, two cfu/0.1 ml after five minutes-treatment and one cfu/0.1 ml after ten minutes-treatment. The numbers of the organism treated with the surfactant containing 23 v/v% ethanol were less than one cfu/0.1 ml after five minutes. 3.(ABSTRACT TRUNCATED AT 250 WORDS)

99mTc-HSA-D has been developed as a new blood pool scanning agent. Clinical comparison of 99mTc-HSA-D and 99mTc-HSA was made in 16 cases. The activity concentration of 99mTc in blood was measured during 2 hours after the injection in five cases. 99mTc-HSA-D showed higher concentration compared to 99mTc-HSA with the passage of time. Quantitative analysis of contrast between left ventricle and septum was performed on end diastolic frames of gated images 10 minutes after the injection. There was no obvious difference between 99mTc-HSA-D and 99mTc-HSA. The subjective comparison of detectability of lesions between the two agents was performed on three directional gated images. 99mTc-HSA-D was superior to 99mTc-HSA, because the images of the latter deteriorated with the passage of time. On anterior view images 1 hour after the injection, left ventricle/lung and abdominal aorta/background count ratios were greater for 99mTc-HSA-D in many cases. There was no obvious difference in liver/background and kidney/background count ratios between the two agents. Urinary excretion of 99mTc was considerably lesser for 99mTc-HSA-D. The results indicated that 99mTc-HSA-D was superior to 99mTc-HSA for cardiac blood pool imaging.
