The following analgesic effects have resulted from irradiating each finger joint (DIP, PIP, and MCP) of patients with rheumatoid arthritis for 20 seconds using the semiconductor laser, “uni-Laser” (10mw, 790nm) from ITO company.
1) Comparison of the post-exposure state with the pre-exposure state in the open test
i) Of 13 cases of joint pain, 7 cases showed improvement and 6 cases showed no change with no case showing aggravation.
ii) Duration of analgesic effect was less than 48 hours in 2 cases, less than 72 hours in 1 case, and more than 96 hours in 3 cases.
2) Comparison of the post-exposure state with the pre-exposure state in the single blind test on a total of 25 patients with rheumatoid arthritis. Twelve patients were exposed to the irradiation twice per week, 10 times a session (irradiated group) and 13 were exposed to the dummy of the above (control group).
i) The irradiated group improved considerably in the number of painful joints, frequency of joint pain, and grasping power. The rate of improvement was superior to that of the control group (P<0.05).
ii) No significant improvement in duration of morning stiffness was shown in either group.

Statistical analyses were made on a total of 242 clinical cases of skin disordersfrom agricultural chemicals in Japanese farmers, using data recorded by physicians on standard forms in 41 hospitals and other medical institutions during the 1982-89 period. The majority of the cases were acute dermatitis (72.3%), followed by chronic dermatitis (19.0%), chemical burns (7.4%) and photosensitive dermatitis (2.1%). Organophosporus insecticides were the most frequent inducer of occupational skin lesions (24.8%), followed by sulfur fungicides (20.7%), polyhaloalkylthio-fungicides (16.1%), and soil disinfectants (7.9%). Main factors contributing to the onset of skin lesions were insufficient clothing on the part of users (46.7%), carelessness (21.9%), unsuitable weather (strong wind) (9.9%) and so forth. Epidemiological features such as sex, age, season, complications, affected sites and prognoses were also analyzed and discussed.

A 64-year-old man was transferred to our hospital because of acute heart failure associated with myocardial infarction. Echocardiography revealed severe mitral regurgitation due to total rupture of the posterior papillary muscle. Following the diagnosis of papillary muscle rupture, intraaortic balloon pumping support was started, and surgery was performed without coronary angiography because of cardiogenic shock and renal dysfunction. The posterior papillary muscle was completely ruptured, and the anterior leaflet of the mitral valve was severely prolapsed. Without resecting the posterior leaflet, mitral valve replacement was successfully performed using a St. Jude Medical^® prosthetic valve. The postoperative course was uneventful except for ventricular tachyarrhythmia which occurred during the acute phase postoperatively. Postoperative coronary angiography demonstrated no significant coronary arterial stenosis. In a patient with cardiogenic shock due to papillary muscle rupture, immediate surgical intervention is recommended as soon as the diagnosis has been established by echocardiography.

Endoscopic ultrasound-guided pancreatic duct drainage (EUS-PD) has emerged as an option in patients with failure of retrograde access to the pancreatic duct (PD) because of difficulty in cannulation or surgically altered anatomy. This article provides a comprehensive review of the techniques and outcomes of EUS-PD, especially EUS-guided pancreatic transmural stenting. The clinical data derived from a total of 401 patients were reviewed in which the overall technical and clinical success rates were 339/401 (85%, range 63%–100%) and 328/372 (88%, range 76%–100%), respectively. Short-term adverse events occurred in 25% (102/401) of the cases, which included abdominal pain (n=45), acute pancreatitis (n=17), bleeding (n=10), and issues associated with pancreatic juice leakage such as perigastric or peripancreatic fluid collection (n=9). In conclusion, although EUS-PD remains a challenging procedure with a high risk of adverse events such as pancreatic juice leakage, perforation, and severe acute pancreatitis, the procedure seems to be a promising alternative for PD drainage in patients with altered anatomy or unsuccessful endoscopic retrograde pancreatography.

A total of 630 clinical cases of occupational skin disorder from agricultural chemicals werestatistically analyzed in Japanese farmers who were recorded by physicians on a standard form from41 hospitals and other medical institutions during the 1972-81 period. The majority of the cases wereacute dermatitis (66.7%). This was followed by chronic dermatitis (24.3%), chemical burns (8.4%) andphotosensitive dermatitis (2.2%). By type to chemicals, the number one skin hazard was sulfurfungicides (32.2%), followed by organophosphorus insecticides (28.6%), polyhaloalkylthio-fungicides (11.4%), and copper fungicides (7.1%). Factors contributing to the onset of any disorder of the skinwere mainly defenseless on the part of users (41.3%), carelessness (20.2%), poor health condition(14.6%), and so forth. Other epidemiological features by sex, age, season, complications, sites of skindisorder, prognosis, etc. were also analyzed and discussed.

We report a 25-year-old man with ventricular septal perforation due to blunt chest trauma. He was transferred by ambulance to our hospital following a traffic accident. On admission, he had no cardiac murmur. Two days later, a pansystolic murmur appeared over the left lower sternal border. Doppler echocardiogram revealed a large left-to-right shunt through a ventricular septal perforation. We postponed surgical treatment as long as possible because he also exhibited bronchial bleeding due to a lung contusion. Surgical repair of the ruptured ventricular septum was performed 8 days after the chest trauma, because the pulmonary to systemic flow ratio was elevated to 4.6 and cardiac function had deteriorated. During the operation, the site of the septal perforation was easily detected by epicardial echocardiography. A 4-cm tear in the muscular septum was closed through a right ventriculotomy using a pericardial patch reinforced with a Dacron patch. Postoperative recovery was uneventful with the exception of transient right ventricular failure. There was no residual shunt.

STUDY DESIGN: Retrospective study. PURPOSE: To obtain information useful in establishing treatment guidelines by evaluating baseline clinical features and treatment outcomes of patients with spinal cord astrocytoma (SCA). OVERVIEW OF LITERATURE: The optimal management of SCA remains controversial, and there are no standard guidelines. METHODS: The study included 20 patients with low-grade and 13 with high-grade SCA surgically treated between 1989 and 2014. Patients were classified according to the extent of surgical resection. Survival was assessed using Kaplan-Meier plots and compared between groups by log-rank tests. Neurological status was defined by the modified McCormick scale and compared between groups by Mann-Whitney U tests. RESULTS: Surgical resection was performed for 19 of 20 low-grade (95%) and 10 of 13 high-grade (76.9%) SCA patients. Only nine patients (27.3%) underwent gross total resection, all of whom had low-grade SCA. Of all patients, 51.5% showed deteriorated neurological status compared to preoperative baseline. Median overall survival was significantly longer for low-grade SCA than that (91 months, 78% at 5 years vs. 15 months, 31% at 5 years; p=0.007). Low-grade SCA patients benefited from more aggressive resection, whereas high-grade SCA patients did not. Multivariate analysis revealed histology status (hazard ratio [HR], 0.30; 95% confidence interval [CI], 0.09-0.98; p<0.05) and postoperative neurological status (HR, 0.12; CI, 0.02-0.95; p<0.05) as independent predictors of longer overall survival. Adjuvant radiotherapy had no significant impact on survival rate. However, a trend for increased survival was observed with radiation cordotomy (RCT) in high-grade SCA patients. CONCLUSIONS: Aggressive resection for low-grade and RCT may prolong survival. Preservation of neurological status is an important treatment goal. Given the low incidence of SCA, establishing strong collaborative, interdisciplinary, and multi-institutional study groups is necessary to define optimal treatments.

STUDY DESIGN: A retrospective study. PURPOSE: The purpose of this study was to obtain useful information for establishing the guidelines for treating high-grade spinal cord gliomas. OVERVIEW OF LITERATURE: The optimal management of high-grade spinal cord gliomas remains controversial. We report the outcomes of the surgical management of 14 high-grade spinal glioma. METHODS: We analyzed the outcomes of 14 patients with high-grade spinal cord gliomas who were surgically treated between 1989 and 2012. Survival was charted with the Kaplan-Meier plots and comparisons were made with the log-rank test. RESULTS: None of the patients with high-grade spinal cord gliomas underwent total resection. Subtotal resection was performed in two patients, partial resection was performed in nine patients, and open biopsy was performed in three patients. All patients underwent postoperative radiotherapy and six patients further underwent radiation cordotomy. The median survival time for patients with high-grade spinal cord gliomas was 15 months, with a 5-year survival rate of 22.2%. The median survival time for patients with World Health Organization grade III tumors was 25.5 months, whereas the median survival time for patients with glioblastoma multiforme was 12.5 months. Both univariate and multivariate Cox proportional hazards models demonstrated a significant effect only in the group that did not include cervical cord lesion as a factor associated with survival (p=0.04 and 0.03). CONCLUSIONS: The surgical outcome of patients diagnosed with high-grade spinal cord gliomas remains poor. Notably, only the model which excluded cervical cord lesions as a factor significantly predicted survival.

Introduction: We report two cases of infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients treated by the palliative care team during the first wave of the coronavirus disease 2019 (COVID-19) pandemic. These patients were receiving interventions for pain control, but subsequently contracted COVID-19, leading to their deaths. Cases: Two patients with hematopoietic tumors had been taking hydromorphone tablets for pain control. Both patients contracted COVID-19 during their clinical course, and displayed happy hypoxia, a typical complication of SARS-CoV-2 infection. Although the rapid systemic deterioration of the patients' conditions were recognized, there were no complaints of breathing difficulties. We attempted to alleviate the symptoms by adjusting the medications, including changes to the administration route. Discussion: When a patient receiving palliative care is infected with SARS-CoV-2, the presence of an underlying condition may cause a rapid deterioration, and opioid titration may be required depending on the characteristics of the symptoms.
