Abstract
Introduction Measurement of blood Favipiravir (FPV) levels and accumulation of data in COVID-19 patients are critical for assessing FPV efficacy and safety. We performed a retrospective study based on measurements of blood levels of FPV and related factors in COVID-19 patients admitted to our hospital. Furthermore, we also investigated the association between blood FPV levels and uric acid level alterations before and after FPV administration. Methods We enrolled 27 COVID-19 patients who had received FPV treatment at Hokushin General Hospital from April 1 to December 31, 2020. Age, gender, COVID-19 severity, presence of comorbidities, and laboratory data for each subject were investigated to identify factors that correlate with blood FPV levels. Uric acid levels were measured before and after FPV administration and a difference between the levels (i.e., a change of uric acid level) was evaluated. Results When a significant univariate variable was input by the stepwise method and a combination of variables that maintained statistical superiority was searched, serum ferritin was the only factor that independently affected blood FPV level. Furthermore, in the high-FPV group (20 μg/mL or more), a significant increase in uric acid levels was observed after FPV administration. The increment value was significantly larger than that in the low-FPV group (less than 20 μg/mL). Conclusions Ferritin level was an important independent factor inversely affecting blood FPV level. Furthermore, a high blood FPV level induced the elevation of uric acid levels in COVID-19 treatment.

Abstract
Implementation of new therapies is usually governed by financial considerations, so efficacy studies should also include cost comparisons. The cost and effectiveness of mandibular conventional dentures (CD, n = 30) and two-implant overdentures (IOD, n = 30) were compared in elderly subjects. Effectiveness (Oral Health Impact Profile, OHIP-20) and cost were measured up to one year post-treatment. Data for subsequent years were estimated by the Delphi method. Using an average life expectancy of 17.9 years, the equalized annual costs (in Canadian dollars) were $399 for CD and $625 for IOD (p < 0.001), and the equalized annual values for the outcome (OHIP-20) were 47.0 for CD and 31.3 for IOD treatment (p < 0.05). These values translate into a yearly additional cost for IOD treatment of $14.41 per OHIP-20 point. These results are key to the implementation of programs to provide this form of therapy for edentulous adults.

Abstract
OBJECTIVE To investigate whether phrenic nerve conduction in the early phase of Guillain- Barre syndrome (GBS) predicts the need for respiratory assistance during the subsequent clinical course. MATERIAL AND METHODS We performed electrophysiological examinations of conventional peripheral nerve conduction and phrenic nerve conduction for GBS patients within 14 days from the onset. We excluded patients who had already been treated with immuno-related therapy and respiratory assistance. RESULTS Fifteen patients were enrolled. Three patients with the sum of phrenic nerve latency longer than 30 ms and the sum of bilateral diaphragmatic compound muscle action potential amplitude smaller than 0.3 mV required respiratory assistance after the conduction test. CONCLUSION Our findings showed that not only delayed distal latency but also decreased amplitude may predict the need for respiratory assistance during the subsequent disease course.

Abstract
BACKGROUND Recently, some studies have suggested that sentinel node biopsy also can be applied to gastric cancer. The authors apply sentinel lymph node biopsy in laparoscopy assisted distal gastrectomy to perform it as safe limited surgery. Limited surgery is a procedure in which the extent of lesion resection and lymph node dissection is reduced. The authors demonstrate that intraoperative diagnosis of lymph node metastasis is useful in this respect. METHODS The study was conducted with 38 patients (29 men and 9 women) who had a preoperative diagnosis of T1 tumor invasion. The patients had a mean age of 66.2 years. Patent blue (1%) was injected submucosally into four or five different sites around the primary tumor at 1 ml per site. Blue-stained lymphatics and lymph nodes could be seen by turning over the greater omentum and the lesser omentum extraperitoneally. If blue nodes were found, biopsy was performed. RESULTS The mean number of blue nodes dissected was 2.5 +/- 1.9. Intraoperative identification and biopsy of blue nodes could be performed for 35 (92.1%) of the 38 patients. Of the 35 patients in whom blue nodes were identified, 4 (9.7%) had metastases in blue nodes confirmed by intraoperative frozen-section diagnosis. Intraoperative frozen-section diagnosis was negative for blue node metastasis in 31 patients. Postoperative permanent section diagnosis also showed no evidence of lymph node metastasis in these 31 patients (100% accuracy, 0% false-negative rates). CONCLUSION The reported method allows observation of blue-stained lymphatics up to 2 h after patent blue injection. Sentinel node biopsy was performed in laparoscopy assisted distal gastrectomy, making it technically equivalent to open gastrectomy. Sentinel node biopsy can serve as a method to determine the appropriate use of laparoscopy assisted distal gastrectomy for management of T1 gastric cancer.

Abstract
A 22-year-old man was admitted to the department of pediatrics of our institute in February 2005, because of pulmonary aspergillosis. He had been diagnosed as hyper immunoglobulin-E syndrome in infancy, and repeated pulmonary infectious desease, such as pulmonary aspergillosis. He received art of right upper lobectomy by pulmonary aspergillosis at the age of 17. In February 2005, he had hemosputum and the chest X-ray showed a giant cavity with niveau in the right lung. In spite of medical treatment by antibiotics and antimycotics, the lesion rapidly increased in size. Therefore, right completion pneumonectomy and omentopexy around the bronchial stump was done. His postoperative course was uneventful.

Abstract
We describe two cases where postinfarction ventricular septal defect (VSD) was treated with a new technique. Application of direct ultrasonography to the right ventricular (RV) wall enables the surgeon to visualize the region and perform appropriate incision into the right ventricle and trabecula resection. The VSD is sealed with gelatin-resorcin-formal (GRF) glue between two patches, one placed on the left ventricular side and the other on the right ventricular side. RV incision provides easy bleeding control and the "sandwich technique" using two patches and GRF sealing provides geometric preservation of the left ventricular shape and prevents residual shunt.

Abstract
BACKGROUND Thoracoscopic simple bullectomy for primary spontaneous pneumothorax (PSP) has a relatively high postoperative recurrence rate and sometimes results in postoperative air leakage. One of the reasons for postoperative recurrence is the regrowth of bullae around the staple line. Therefore, reinforcement of the visceral pleura around the staple line is a reasonable way to prevent postoperative air leaks and recurrence. This study was done to determine the efficacy in preventing postoperative air leak and recurrent pneumothorax of widely covering the staple line with absorbable mesh after thoracoscopic bullectomy. METHODS Wide coverage of the staple line with absorbable mesh was performed on 114 patients with PSP. These patients were retrospectively compared with 126 patients who underwent thoracoscopic simple bullectomy alone. RESULTS The postoperative duration of chest drainage in the coverage group (mean, 1 day; range, 0-5) was significantly shorter than that in the simple bullectomy group (mean, 3 days; range 0-20). A prolonged air leak (>7 days) occurred in six patients in the simple bullectomy group, but there were no such leaks in the coverage group. Recurrent pneumothorax occurred in three patients (2.6%) in the coverage group and 12 patients (9.5%) in the simple bullectomy group. CONCLUSION Wide coverage of the staple line with absorbable mesh is effective in preventing postoperative air leak and in decreasing the recurrence rates of PSP.

Abstract
A 66-year-old woman with aortic stenosis underwent an aortic root replacement with a composite graft and coronary artery reconstruction 2 years before presentation. On coronary angiography performed 2 years after operation, saphenous vein graft (SVG) to right coronary artery and SVG to first diagonal branch had both become totally occluded. SVG to left anterior descending artery showed 75% stenosis on the heel side of the distal anastomosis. The patient underwent a second coronary artery bypass via a left thoracotomy (the left internal thoracic artery was anastomosed to the first diagonal branch by interposing it with the left radial artery) and a small laparotomy (the right gastroepiploic artery was anastomosed to the right coronary artery) without a cardiopulmonary bypass. This approach is preferable to avoiding both a resternotomy and cardiopulmonary bypass in patients requiring repeat surgery.

Abstract
A case of a 52-year-old male presented with an unusual penetrating brain injury with nasal entry. At admission he had erythema of periorbital soft tissue in the left eye and epistaxis. His neurological condition was lethargic (Glasgow Coma Scale of 13) with nonfluent aphasia. Computed tomography scan revealed intracranial contusion hematoma in the left frontal lobe and fracture of the left frontal base, which were treated surgically. At the 6-month follow-up he still showed nonfluent aphasia. Disturbances, mostly cognitive, were noted on his psychological tests. A survey of the literature reveals a few cases of this nature in penetrating brain injury with nasal entry. A penetrating brain injury with nasal entry which causes nonfluent aphasia is discussing.

Abstract
BACKGROUND The expression of tissue inhibitor of matrix metalloproteinase (TIMP) 1 in tumour tissue from patients with colorectal carcinoma has been reported to be related to disease progression. However, the clinical significance of plasma TIMP-1 has not been fully elucidated. METHODS The plasma level of TIMP-1 protein was determined by enzyme-linked immunosorbent assay in samples from 54 patients who underwent resection of the primary tumour. RESULTS Plasma TIMP-1 levels were associated significantly with depth of invasion and metastasis to lymph nodes and liver. Circulating TIMP-1 levels were significantly higher in patients with serosal invasion, liver metastases and Dukes' stage C tumours. Using a cut-off value of 160 ng/ml, serosal invasion and Dukes' C stage could be predicted with an accuracy of 68.5 per cent. With a cut-off value of 170 ng/ml, metastasis to the lymph node and liver could be predicted with an accuracy of 66.7 and 70.4 per cent respectively. These values were greater than those for carcinoembryonic antigen and CA19-9. CONCLUSION These data suggest that the plasma concentration of TIMP-1 correlates with both invasion and metastasis in patients with colorectal carcinoma.

Abstract
To date, the pharmacological approach to cerebral vasospasm following subarachnoid hemorrhage has been hampered in part by an inability to attain sufficiently high concentrations of vasodilator drugs in the cerebrospinal fluid (CSF). To overcome this limitation of current drug therapy, we have developed a sustained-release preparation of protein kinase inhibitor Fasudil. Cerebral vasospasm in rats was induced by double-injection method. Treated rats received 0.417 mg liposome-entrapped Fasudil via the cisterna magna and control rats received drug-free liposomes in the same manner. The diameter of the basilar artery was assessed at 7 days after the initial blood injection. Vasoconstriction of the rat basilar artery was significantly reduced in group treated with liposomal Fasudil compared to the control group (treated group: 87.7 +/- 6.18%, n= 10; control group: 66.3 +/- 9.82%, n = 10; ***P< 0.001). This new approach for cerebral vasospasm may have significant potential for use in the clinical setting.

Abstract
Pharmacological treatment for cerebral ischemia cannot attain sufficiently high concentrations of the drugs in the cerebrospinal fluid (CSF) without precipitating systemic side effects. The objective of this study is the development of a liposomal drug delivery system that maintains effective concentrations of protein kinase inhibitors fasudil in the CSF, resulting in neuroprotection against cerebral ischemia. Focal cerebral ischemia in rats was induced by middle cerebral artery occlusion using an intraluminal suture technique. Treated rats received 0.25 mg liposome-entrapped fasudil via the cisterna magna 2 hours after ischemic insult. Control rats received drug-free liposomes. Neurological condition and the infarct size were assessed at 24 and 72 hours after ischemia. The concentration of liposome-entrapped fasudil in the CSF was measured before sacrifice. Treated animals showed significantly improved neurological outcomes after the 24-hour observation period compared to the control group (p < 0.001). Treatment with 0.25 mg liposomal fasudil resulted in a reduction in the infarct area (24 hours: 29.0 +/- 4.4%, 72 hours: 28.1 +/- 3.9% of total brain slices) compared to controls (49.6 +/- 4.6%, p < 0.001), but there was no statistical difference between 24 and 72 hours. At 24 hours post-administration, CSF concentrations of liposome-entrapped fasudil were 45.4 +/- 31.5 micrograms/ml (20% of the injected dose). A single intrathecal injection of liposomal fasudil can maintain a therapeutic drug concentration in the CSF over a period of time, significantly decreasing infarct size in a rat model of acute ischemia.

Abstract
A 65-year-old woman was admitted to the hospital because of anterior chest pain. Computed tomography and transthoracic 2-D echocardiogram demonstrated aortic valvular stenosis with calcification of whole aortic root. Cardiac catheterization study showed a transaortic pressure gradient of 73 mmHg and coronary angiography showed 75% stenosis at the right coronary ostia. Aortic valve replacement and coronary artery bypass grafting were planned. At operation, sinotubular junction and bilateral coronary ostia severely calcified with stenosis, prompted us to translocate the aortic valve with the composite graft, a 19 mm Bicarbon prosthesis and 25 mm woven Dacron graft. The postoperative course was uneventful. On cardiac catheterization done 27 days after operation, satisfactory valve motion and patent coronary bypass grafts were confirmed.

MKN-1 gastric cancer cells were treated with the IC50 of 5-FU in the presence of interferon-gamma (IFN-gamma). In addition, s-methylisothiourea (an antagonist of inducible nitric oxide synthase) or anti-TNF-alpha antibody was added to the culture medium. Production of NO was measured by nitrite assay, TNF-alpha was measured by enzyme-linked immunoabsorbent assay, antitumor activity was evaluated by 3-[4,5-dimethylethiazol-2-yl]-2,5-dipheniltetrasolium bromide (MTT) assay. After 5-FU treatment in the presence of IFN-gamma, NO and TNF-alpha were produced and anti-tumor activity was enhanced. In contrast, s-methylisothiourea abolished the antitumor activity of 5-FU treatment. Anti-TNF-alpha antibody inhibited NO production and decreased the antitumor activity. 5-FU induces NO production by gastric cancer cells, and NO participates in antitumor activity in gastric cancer cells. These effects may be mediated by TNF-alpha production.

Abstract
The authors studied the extravasation of contrast enhancement on magnetic resonance (MR) imaging within 6 hours after head injury in 10 patients with 12 intracranial haemorrhagic lesions. The decision for surgical intervention was made by neurological examination, computed tomographic scan, and contrast extravasation on MR imaging. Nine of 10 patients showed extravasation of contrast agent and one patient showed equivocal findings of contrast extravasation. All intracranial lesions with contrast extrav asation led to enlargement in size. With the exception of 1 patient who showed equivocal findings of contrast extravasation, 9 patients needed surgical evacuation of the haemorrhagic lesions. The results of the current study imply that extravasation of contrast medium indicates persistence of post-traumatic bleeding. MR imaging with gadolinium enhancement in acutely head injured patients may be used to predict the development of haemorrhagic lesions and could be helpful in decision making for surgical intervention.
