Abstract
BACKGROUND/PURPOSE There is currently no consensus on the use of endoscopic papillectomy (EP) for early stage duodenal ampullary adenocarcinoma. This study aimed to evaluate the feasibility of EP for patients with early stage duodenal ampullary adenocarcinoma. METHODS Patients who underwent EP for ampullary adenocarcinomas were investigated. Complete and clinical complete resection rates were evaluated. Clinical complete resection was defined as either complete resection or resection with positive or unknown margins but no cancer in the surgically resected specimen, or no recurrence on endoscopy after at least a 1-year follow-up. RESULTS Adenocarcinoma developed in 30 patients (carcinoma in situ [Tis]: 21, mucosal tumors [T1a(M)]: 4, tumors in the sphincter of Oddi [T1a(OD)]: 5). The complete resection rate was 60.0% (18/30) (Tis: 66.7% [14/21], T1a[M]: 50.0% [2/4], and T1a[OD]: 40.0% [2/5]). The mean follow-up period was 46.8 months. The recurrence rate for all patients was 6.7% (2/30). The clinical complete resection rates of adenocarcinoma were 89.2% (25/28); rates for Tis, T1a(M), and T1a(OD) were 89.4% (17/19), 100% (4/4), and 80% (4/5), respectively. CONCLUSIONS EP may potentially achieve clinical complete resection of early stage (Tis and T1a) duodenal ampullary adenocarcinomas.

Abstract
PURPOSE The 2021 World Health Organization (WHO) classification of central nervous system (CNS) tumors uses an integrated approach involving histopathology and molecular profiling. Because majority of adult malignant brain tumors are gliomas and primary CNS lymphomas (PCNSL), rapid differentiation of these diseases is required for therapeutic decisions. In addition, diffuse gliomas require molecular information on single-nucleotide variants (SNV), such as IDH1/2. Here, we report an intraoperative integrated diagnostic (i-ID) system to classify CNS malignant tumors, which updates legacy frozen-section (FS) diagnosis through incorporation of a qPCR-based genotyping assay. EXPERIMENTAL DESIGN FS evaluation, including GFAP and CD20 rapid IHC, was performed on adult malignant CNS tumors. PCNSL was diagnosed through positive CD20 and negative GFAP immunostaining. For suspected glioma, genotyping for IDH1/2, TERT SNV, and CDKN2A copy-number alteration was routinely performed, whereas H3F3A and BRAF SNV were assessed for selected cases. i-ID was determined on the basis of the 2021 WHO classification and compared with the permanent integrated diagnosis (p-ID) to assess its reliability. RESULTS After retrospectively analyzing 153 cases, 101 cases were prospectively examined using the i-ID system. Assessment of IDH1/2, TERT, H3F3AK27M, BRAFV600E, and CDKN2A alterations with i-ID and permanent genomic analysis was concordant in 100%, 100%, 100%, 100%, and 96.4%, respectively. Combination with FS and intraoperative genotyping assay improved diagnostic accuracy in gliomas. Overall, i-ID matched with p-ID in 80/82 (97.6%) patients with glioma and 18/19 (94.7%) with PCNSL. CONCLUSIONS The i-ID system provides reliable integrated diagnosis of adult malignant CNS tumors.

Abstract
In IDH-mutant astrocytoma, IDH2 mutation is quite rare and biological mechanisms underlying tumor progression in IDH2-mutant astrocytoma remain elusive. Here, we report a unique case of IDH2 mutant astrocytoma, CNS WHO grade 3 that developed tumor progression. We performed a comprehensive genomic and epigenomic analysis for primary and recurrent tumors and found that both tumors harbored recurrent IDH2R172K and TP53R248W mutation with CDKN2A/B hemizygous deletion. We also found amplifications of CDK4 and MDM2 with PDGFRA gain in the recurrent tumor and upregulated protein expressions of these genes. We further developed, for the first time, a xenograft mouse model of IDH2R172K and TP53R248W mutant astrocytoma from the recurrent tumor, but not from the primary tumor. Consistent with parent recurrent tumor cells, amplifications of CDK4 and MDM2 and PDGFRA gain were found, while CDKN2A/B was identified as homozygous deletion in the xenografts, qualifying for integrated diagnosis of astrocytoma, IDH2-mutant, CNS WHO grade 4. Cell viability assay found that CDK4/6 inhibitor and PDGFR inhibitor potently decreased cell viability in recurrent tumor cells, as compared to primary tumor cells. These findings suggest that gene alterations that activate retinoblastoma (RB) signaling pathways and PDGFR may drive tumor progression and xenograft formation in IDH2-mutant astrocytoma, which is equivalent to progressive IDH1-mutant astrocytoma. Also, our findings suggest that these genomic alterations may represent therapeutic targets in IDH2-mutant astrocytoma.

Abstract
Risk factors of severe coronavirus disease 2019 (COVID-19) have been previously reported; however, histological risk factors have not been defined thus far. The aim of this study was to clarify subclinical hidden interstitial lung disease (ILD) as a risk factor of severe pneumonia associated with COVID-19. We carefully examined autopsied lungs and chest computed tomography scanning (CT) images from patients with COVID-19 for interstitial lesions and then analyzed their relationship with disease severity. Among the autopsy series, subclinical ILD was found in 13/27 cases (48%) in the COVID-19 group, and in contrast, 8/65 (12%) in the control autopsy group (p = 0.0006; Fisher's exact test). We reviewed CT images from the COVID-19 autopsy cases and verified that subclinical ILD was histologically detectable in the CT images. Then, we retrospectively examined CT images from another series of COVID-19 cases in the Yokohama, Japan area between February-August 2020 for interstitial lesions and analyzed the relationship to the severity of COVID-19 pneumonia. Interstitial lesion was more frequently found in the group with the moderate II/severe disease than in the moderate I/mild disease (severity was evaluated according to the COVID-19 severity classification system of the Ministry of Health, Labor, and Welfare [Japan]) (moderate II/severe, 11/15, 73.3% versus moderate I/mild, 108/245, 44.1%; Fisher exact test, p = 0.0333). In conclusion, it was suggested that subclinical ILD could be an important risk factor for severe COVID-19 pneumonia. A benefit of these findings could be the development of a risk assessment system using high resolution CT images for fatal COVID-19 pneumonia.

Abstract
In the fifth edition central nervous system tumours volume of the WHO Classification of Tumours series, gliomas, glioneuronal tumors, and neuronal tumors are divided into six groups. The term "circumscribed" is used to refer to a relatively contained growth pattern, as compared to other inherently "diffuse" tumors. Circumscribed astrocytic gliomas include six types: pilocytic astrocytoma, high-grade astrocytoma with piloid features, pleomorphic xanthoastrocytoma, subependymal giant cell astrocytoma, chordoid glioma, and astroblastoma, MN1-altered. The vast majority of circumscribed astrocytic gliomas harbor genetic alterations in the mitogen-activated protein kinase pathway. Here, we review the circumscribed astrocytic gliomas, including etiology, clinical and imaging features, pathology and molecular genetics, treatment, and prognosis. This study will lead to better understanding of these newly classified tumors.

Abstract
We present a case of lung carcinoma with a unique biphasic feature. The patient was a 67-year-old male smoker with idiopathic pulmonary fibrosis (IPF). A subpleural tumor in the left lower lobe, embedded in fibrotic tissue, was resected. Histologically, the tumor consisted of major and minor components of mucoepidermoid carcinoma (MEC) and surrounding conventional lepidic adenocarcinoma, respectively. Both components had the same TP53 somatic mutation (p.V157F) but not Mastermind-like 2 (MAML2) gene rearrangement. The two components may have developed from an identical origin. The tumor could be trans-differentiating from lepidic adenocarcinoma to MEC, possibly promoted by IPF-induced tissue damage. The final diagnosis was "adenosquamous carcinoma with mucoepidermoid-like features (that may originate from lepidic adenocarcinoma)." This case has implications for the potential histogenesis of peripheral lung MEC. Over time, the MEC would expand and outgrow the lepidic adenocarcinoma, making it impossible to distinguish between fake and true MEC. The present case suggests that peripheral MEC could differ from proximal MEC in its histogenesis and molecular genetics. Thus, careful examination is necessary to diagnose peripheral lung MEC, particularly in patients with interstitial lung diseases.

Abstract
AIMS In COVID-19 pneumonia, early detection and appropriate treatment are essential to prevent severe exacerbation. Therefore, it is important to understand the initiating events of COVID-19 pneumonia. However, at present, the literature about early stage disease has been very limited. Here, we investigated the earliest histopathological changes and gene expression profiles associated with COVID-19 pneumonia. METHODS AND RESULTS We carefully examined 25 autopsied cases with different clinical courses. Dilation of capillaries and edematous thickening of the alveolar septa were found even in areas that macroscopically looked almost normal. Pneumocytes, histocytes/macrophages, and vascular endothelial cells were immunohistochemically positive for tissue factor, which is an important early responder to tissue injuries. Comprehensive gene expression analyses revealed that those lesions presented differential profiles compared to those of control lungs and were associated with a significant upregulation of the lysosomal pathway. CONCLUSIONS Alveolar capillary dilation and edematous thickening may be the earliest histopathological change detected in COVID-19 pneumonia. Intensive investigations of such lesions may lead to an understanding of the initiating event of not only COVID-19 pneumonia but also of general diffuse alveolar damage.

Abstract
Background:
Brain metastases with hematoma are clinically important as they indicate the potential for rapid neurological deterioration. Non-uterine leiomyosarcoma-derived brain metastases are particularly rare, and their clinical features, including the bleeding rate, are unclear. Herein, we present a rare case of thigh leiomyosarcoma-derived brain metastasis with intratumoral hematoma and review previous case reports.
Case Description:
A 68-year-old man with a right thigh leiomyosarcoma presented with multiple brain metastases. The patient received stereotactic radiotherapy; however, he reported sudden right-sided hemiparesis. We found a right frontal irradiated lesion with intratumoral hemorrhage and performed gross total tumor resection. Histopathological examination showed highly atypical cells with prominent necrosis and hemorrhage. Abnormal thin-walled vessels were prominent within the brain tumor, and vascular endothelial growth factor was diffusely expressed immunohistopathologically. To date, 11 cases of brain metastasis from non-uterine leiomyosarcoma, including the present case, have been reported. Of note, six patients had hemorrhage. Three out of six patients presented with hemorrhage before therapeutic intervention, three cases were from residual sites after surgery or radiation.
Conclusion:
More than half the patients with non-uterine leiomyosarcoma-derived brain metastases presented with intracerebral hemorrhage. Furthermore, these patients are at risk of developing rapid neurological deterioration due to intracerebral hemorrhage.

Abstract
Although synovial sarcoma is a relatively common soft tissue sarcoma, primary intra-articular cases are extremely rare. Herein, we report a case of primary intra-articular synovial sarcoma arising from the hip joint, that was initially treated with hip arthroscopy. A 42-year-old male presented with a history of pain in the left hip for 7 years. Radiography and magnetic resonance imaging revealed the primary intra-articular lesion and simple excision with an arthroscopy was performed. Histological findings revealed spindle cell proliferation with abundant psammoma bodies. SS18 gene rearrangement was confirmed by fluorescence in situ hybridization, and the tumor was diagnosed as synovial sarcoma. Adjuvant chemotherapy and radiotherapy were performed. Local control without metastasis was achieved 6 months after excision. This is the first case of intra-articular synovial sarcoma of the hip joint excised via hip arthroscopy. When an intra-articular lesion is identified, malignancies such as synovial sarcoma should be included in the differential diagnosis.

Abstract
BACKGROUND Multiplex gene-panel tests have recently been developed, including the Oncomine Dx Target Test multi-CDx system (ODxTT), and are commonly used to determine the adaptation of molecular-targeting drugs in non-small cell lung cancer. However, in actual clinical settings, we obtain false results owing to the small biopsy samples. We aimed to optimize tissue preparation methods to improve the success rate. PATIENTS AND METHODS We investigated 88 biopsy samples. The area and nucleated cell count in the first cut section were quantified using a morphometric software. Pathological parameters, including "total tissue area" and "total nucleated cell count," were calculated by multiplying the total number of slides submitted to ODxTT. Optimal cutoff values to obtain the best success rate were also determined. Additionally, we morphometrically measured actual tumor cell proportions and attempted to determine the lower limit possible to detect mutations. RESULTS Optimal cutoff values for "total nucleated cell count" and "total tissue area" were 132,885 and 32.94 mm2, respectively. The actual tumor cell proportions ranged from 4.6 to 97.7%. Even in cases with actual tumor cell proportions of less than 20% (ranging from 4.6 to 19.7%), there was no false negative. CONCLUSION Thus, we proposed the pathological criteria for accurate ODxTT. Our result suggested that tumor cell proportions of less than 20% (around 5%) could be applicable for ODxTT. We hope that our results will help pathologists to choose between the multi-plex test (ODxTT) or single-plex test in routine diagnostics.

Abstract
We report the first case with COVID-19-like acute respiratory distress syndrome after mRNA-1273 SARS-CoV-2 vaccination. An 88-year-old woman developed dyspnea several hours after vaccination with the second dose of mRNA-1273. She was hospitalized on day nine due to worsening dyspnea. Chest computed tomography showed bilateral ground-glass opacities and consolidations, mainly in the peripheral lung areas. Repeat polymerase chain reaction tests for SARS-CoV-2 were negative, although the serum level of antibodies against spike protein was extremely elevated. Her condition did not improve with high-dose corticosteroids and high-flow nasal cannula oxygen therapy; she died on day 18. Autopsy findings revealed very early-phase diffuse alveolar damage in the whole lung without other lung diseases. The clinical and pathological findings suggested vaccine-induced acute respiratory distress syndrome. Serological and pathological tests might be useful to differentiate the disease from COVID-19.

Abstract
PURPOSE Molecular targeted therapy using BRAF and/or MEK inhibitors has been applied to BRAFV600E mutant high-grade gliomas (HGGs); however, the therapeutic effect is limited by the emergence of drug resistance. EXPERIMENTAL DESIGN We established multiple paired BRAFV600E mutant HGG patient-derived xenograft (PDX) models based on tissues collected prior to and at relapse after molecular targeted therapy. Using these models, we dissected treatment resistant mechanisms for molecular targeted therapy and explored therapeutic targets to overcome resistance in BRAFV600E HGG models in vitro and in vivo. RESULTS We found that, despite causing no major genetic and epigenetic changes, BRAF and/or MEK inhibitor treatment deregulated multiple negative feedback mechanisms, which led to the re-activation of the MAPK pathway through c-Raf and AKT signaling. This altered oncogenic signaling primarily mediated resistance to molecular targeted therapy in BRAFV600E mutant HGG. To overcome this resistance mechanism, we performed a high-throughput drug screening to identify therapeutic agents that potently induce additive cytotoxicity with BRAF and MEK inhibitors. We discovered that HSP90 inhibition combined with BRAF/MEK inhibition coordinately deactivated the MAPK and AKT/mTOR pathways, and subsequently induced apoptosis via dephosphorylation of GSK3β (Ser9) and inhibition of Bcl-2 family proteins. This mediated potent cytotoxicity in vitro and in vivo in refractory models with acquired resistance to molecular-targeted therapy. CONCLUSIONS The combination of an HSP90 inhibitor with BRAF or MEK inhibitors can overcome the limitations of the current therapeutic strategies for BRAFV600E mutant HGG.

Abstract
Partial deletions in chromosomes 1p and 19q are found in a subset of astrocytic tumors; however, it remains unclear how these alterations affect their histological features and prognosis. Herein, we present 3 cases of isocitrate dehydrogenase (IDH)-mutant astrocytoma with chromosome 19q13 deletion. In the first case, the primary tumor harbored an IDH1 mutation with chromosome 1p/19q partial deletions, which covered 19q13 and exhibited a durable initial response to radiotherapy and temozolomide (TMZ) treatment. However, the tumor lost the chromosome 1p/19q partial deletions at recurrence and became resistant to TMZ. Histologically, an oligodendroglioma-like feature was found in the primary tumor but not in the recurrent tumor. Capicua transcriptional repressor (CIC), located on 19q13, was less expressed in the primary tumor but was highly expressed in the recurrent tumor. Similar histological findings were observed in 2 other astrocytic tumors with IDH1 or IDH2 mutations. These tumors also had chromosome 19q13 deletion, including the CIC gene, weakly expressed CIC, and oligodendroglioma-like morphology. These tumors recurred at 6 and 32 months, respectively. These findings suggest that IDH-mutant astrocytoma with chromosome 19q13 partial deletion, including the CIC gene, may induce an oligodendroglioma-like phenotype, but the clinical prognosis may not be similar to that of genetically defined oligodendroglioma.

Abstract
A 78-year-old woman in complete remission of mass-forming primary central nervous system lymphoma (PCNSL) showed diffuse leukoencephalopathy as well as corticospinal tract lesions with intense gadolinium enhancement on magnetic resonance imaging (MRI). She died 3 months later. In line with the MRI findings, pathological examination revealed dense infiltration of atypical lymphoid cells, consistent with a diagnosis of lymphomatosis cerebri (LC)-type PCNSL. This is the first report of LC in which the corticospinal tracts demonstrated robust contrast enhancement directly corresponding to the neuropathological findings, and it is also a rare instance in which LC presented as a recurrence of typical PCNSL.

Abstract
AIMS Hereditary leiomyomatosis and renal cell cancer (HLRCC) is an autosomal dominant disorder caused by germline mutations in fumarate hydratase (FH). Affected families have an increased risk of renal cell carcinoma (RCC). HLRCC-associated RCC (HLRCC-RCC) is highly aggressive. Clinicopathological information of genetically diagnosed patients with HLRCC-RCC contributes to the establishment of effective therapies. METHODS Ten Japanese patients with HLRCC-RCC were enrolled in the study. Genetic testing for FH was carried out. Somatic mutations in FH and immunohistochemical analyses of FH and B7 family ligands (PD-L1 and B7-H3) were investigated in 13 tumours. Copy number variations were evaluated in two tumours. RESULTS All patients had FH germline mutations. Regarding histology, most tumours had type 2 papillary architecture or tubulocystic pattern or both. All tumours were FH deficient by immunohistochemistry. Ten tumours were positive for PD-L1, and 12 tumours were positive for B7-H3. Somatic mutation analysis demonstrated loss of heterozygosity of FH in 10 tumours. Copy number variation analysis revealed uniparental disomy between 1q24.2 and 1q44 encompassing FH; gain of chromosome 2 p was also common. All patients had either metastases or residual tumours. Three patients died of HLRCC-RCC and one of colon cancer, whereas the other six are currently alive, including two without recurrence. CONCLUSIONS HLRCC-RCCs appear to have unique molecular profiles, including PD-L1 expression. One patient had complete response to immunotherapy, which may be an option for HLRCC-RCC.

Abstract
The mosquito Aedes aegypti (L.) is the primary vector of various infectious viruses and is typified by a polymorphic color and abundance of white scales on the body. It has been conventionally separated into two subspecies, Ae. aeg. formosus (Walker) (Aaf) and Ae. aeg. aegypti (L.) (Aaa), with Aaf considered a 'sylvan' form and Aaa a 'domestic' form. Because the two subspecies show different susceptibilities to dengue viruses it is important to understand their distribution. In this study, we collected larvae from artificial and natural habitats in southern Kenya and reared them to adults to morphologically identify subspecies. We describe the geographical distribution and relative abundance of Aaa and Aaf in Kenya, and estimate the environmental factors associated with their distributions by GIS using climate and environment data. A total of 5,243 Ae. aegypti adults were collected from 249 sites, with Aaa accounting for 22% of the specimens. The relative abundance of Aaa was higher in coastal areas versus sites in western Kenya. Aaa abundance was also higher in urbanized than forested areas, which is consistent with known ecology. In contrast and inconsistent with previous studies, both Aaa and Aaf were sympatric in artificial and natural habitats. The high relative abundance of Aaa in coastal areas might derive from old populated cities, climate, and/or introduction from abroad.

Abstract
Prostate basal cell carcinoma (PBCC) accounts for 0.01% of all prostate cancers. A 68-year-old man complained of dysuria for 5 years on his initial visit. His PSA level was 3.87 ng/mL. Due to a diagnosis of benign prostate hyperplasia, he underwent transurethral resection of the prostate. A pathological examination revealed that basal cell-like atypical cells made alveolar with palisadal layout. Immunohistochemical analysis showed positive 34β12, P63, and Ki-67. Based on these findings, PBCC was diagnosed. Then, we performed radical prostatectomy. He was free from recurrence 22 months after the operation. We herein report an extremely rare case of PBCC.

Abstract
Ductal adenocarcinoma is an unusual variant of adenocarcinoma of the prostate. A 73-year-old male was referred to our hospital for the further examination of an elevated prostate-specific antigen level of 23.4 ng/mL. Radical prostatectomy (RP) was performed based on the diagnosis obtained by a prostate needle biopsy. The RP specimen revealed ductal adenocarcinoma of the prostate with positive capsular penetration. We herein report a rare case of ductal adenocarcinoma of the prostate.

Abstract
OBJECTIVES This study investigated oxidative stress in the liver, by determining hepatic expression and serum levels of γ-glutamyltranspeptidase (GGT) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in different stages of nonalcoholic fatty liver disease (NAFLD), and assessed whether GGT can differentiate between the various stages of NAFLD. METHODS Expression of GGT and 8-OHdG was examined in biopsy specimens by immunohistochemistry, and serum GGT and 8-OHdG levels were measured by enzyme-linked immuno sorbent assays in patients with simple fatty liver (n = 10), nonalcoholic steatohepatitis (NASH; n = 10) and, as a control, in alcoholic liver disease (ALD; n = 10). RESULTS Hepatic tissue expression of GGT and 8-OHdG was seen in ALD, NASH and fatty liver patients. The percentage of hepatocytes positive for 8-OHdG expression and serum 8-OHdG levels was significantly higher in patients with NASH than simple fatty liver. Serum GGT levels were increased in all cases with ALD, NASH and fatty liver, and correlated significantly with serum levels of 8-OHdG in ALD and NASH, but not in simple fatty liver. CONCLUSIONS Levels of GGT in fatty liver patients may compensate for mild oxidative stress by repressing 8-OHdG levels and preventing progression to NASH; however further oxidative stress leads to increased levels of 8-OHdG and the development of NASH.

Abstract
OBJECTIVE To investigate the possibility of in vivo gene transfer by attempting to transfer the neuronal nitric oxide synthase (nNOS) gene into rat bladder using electroporation. MATERIALS AND METHODS The bladder was exposed through an abdominal midline incision in 8-week-old male rats. Plasmid DNA of the marker genes green fluorescent protein (GFP) and luciferase, and the nNOS gene, was then injected into the subserosal space of the bladder and electroporation applied. At 72 h after gene transfer, GFP and luciferase were assayed in the isolated bladder and immunohistochemical staining used to detect nNOS; NO(x) released from isolated bladder strips was also assessed using microdialysis and high-performance liquid chromatography. RESULTS From the luciferase assay, 45 V, 1 Hz, 50 ms and eight pulses were selected as the optimum conditions for electroporation. Bladder specimens with GFP genes injected by electroporation showed bright and numerous sites of GFP expression in the smooth muscle layer. In rats with the nNOS gene injected by electroporation there was marked nNOS immunoreactivity, and NO(x) released from bladder strips was significantly greater than in the control groups. CONCLUSIONS These results suggest that electroporation is a useful technique for in vivo gene transfer into rat bladder smooth muscles, and that the nNOS gene transferred by this procedure functionally expresses and contributes to NO production.

Abstract
Airway hyperresponsiveness (AHR), goblet cell metaplasia, and mucus overproduction are important features of bronchial asthma. To elucidate the molecular mechanisms behind these pulmonary pathologies, we examined for genes preferentially expressed in the lungs of a murine model of allergic asthma by using suppression subtractive hybridization (SSH). We identified a gene called gob-5 that had a selective expression pattern in the airway epithelium with AHR. Here, we show that gob-5, a member of the calcium-activated chloride channel family, is a key molecule in the induction of murine asthma. Intratracheal administration of adenovirus-expressing antisense gob-5 RNA into AHR-model mice efficiently suppressed the asthma phenotype, including AHR and mucus overproduction. In contrast, overexpression of gob-5 in airway epithelia by using an adenoviral vector exacerbated the asthma phenotype. Introduction of either gob-5 or hCLCA1, the human counterpart of gob-5, into the human mucoepidermoid cell line NCI-H292 induced mucus production as well as MUC5AC expression. Our results indicated that gob-5 may play a critical role in murine asthma, and its human counterpart hCLCA1 is therefore a potential target for asthma therapy.

Abstract
UNLABELLED Shivering has been proposed as an etiology of postoperative hypoxemia. The difficulty with this theory is that hypoxemia inhibits shivering in unanesthetized cats, rats, and humans. However, anesthesia inhibits many protective reflexes, including the ventilatory response to hypoxemia. We therefore tested the hypothesis that arterial hypoxemia fails to inhibit shivering in lightly anesthetized rabbits. Rabbits were intubated and instrumented during exposure to surgical concentrations of anesthesia, and anesthesia was then maintained with 0.2 minimum alveolar anesthetic concentration isoflurane. The core was cooled at a rate of 2-3 degrees C/h by perfusing water at 10 degrees C through a colonic thermode. Core temperatures were recorded from the distal esophagus. Sustained, vigorous shivering was considered physiologically significant. The core temperature that triggering significant shivering identified the thermoregulatory threshold for this response. Arterial blood was sampled for gas analysis at the shivering threshold in each rabbit. Hypoxemia linearly reduced the shivering threshold from 36.7 degrees C at 130 mm Hg to 35.4 degrees C at 50 mm Hg (threshold = PaO2.0.019 + 34.3; r2 = 0.49). We failed to confirm our hypothesis: instead, even mild hypoxemia reduced the shivering threshold >1 C. A 1 C decrease in the shivering threshold is likely to prevent or stop most postoperative shivering because it exceeds the reduction produced by many effective anti-shivering drugs. These data do not support the theory that shivering causes postoperative hypoxemia. IMPLICATIONS Shivering has been proposed as an etiology of postoperative hypoxemia. Our data, in contrast, show that mild hypoxemia inhibits shivering. Shivering is thus unlikely to be a cause of postoperative hypoxemia.

Abstract
In the N-terminal region of the alpha-helix of the c-type lysozymes, two Asx residues exist at the 18th and 27th positions. Hen lysozyme has Asp18/Asn27 (18D/27N), and we prepared three mutant lysozymes, Asn18/Asn27 (18N/27N), Asn18/Asp27 (18N/27D), and Asp18/Asp27 (18D/27D). The stability of the wild-type (18D/27N) lysozyme supported the existence of a hydrogen bond between the side chain of Asp18 and the amide group at the N1 position in the alpha-helix, while the stability of the 18N/27D lysozyme supported the presence of the capping box between the Ser24 (N-cap) and Asp27 residues. Although electrostatic repulsion was observed between Asp18 and Asp27 residues in 18D/27D lysozyme, the dissociation of each residue contributed to stabilizing the B-helix in 18D/27D lysozyme through hydrogen bonding and charge-helix macrodipole interaction. This is the first evidence that two neighboring negative charges at the N-terminus of the helix both increased the stability of the protein.

Abstract
PURPOSE To compare distal oesophageal (reference) temperature with "deep-sternal," "deep-forehead," and tracheal temperatures, establishing the accuracy and precision of each. METHODS We studied 20 patients undergoing general anaesthesia for gynaecological surgery. Their lungs were mechanically ventilated with a circle system, at a fresh-gas flow rate of 6 L.min-1 Respiratory gases were not warmed or humidified. Tracheal temperatures were recorded from a Trachelon tube inserted approximately 21 cm. Deep-body temperatures were measured at the sternum and forehead using a Coretemp thermometer. The principle of the method is to null thermal flux through a cutaneous disk, thus obliterating thermal gradients between the sides of the disk, skin surface, and subcutaneous tissues. Distal oesophageal temperatures were measured from thermocouples incorporated into oesophageal stethoscopes. Tracheal and deep-tissue temperatures were compared with oesophageal temperature using regression and Bland and Altman analyses. RESULTS Tracheal, sternal, and forehead temperatures correlated similarly with distal oesophageal temperature, correlation coefficients (r2) being 0.7 in each case. The offset (oesophageal temperature minus study site) was considerably larger for tracheal temperature (0.7 degree C) than for the other sites (0.2 degree C). However, the precision was only 0.3 degree C at each site. CONCLUSION Our data suggest that tracheal temperatures may not be an adequate substitute for conventional core-temperature monitoring sites. In contrast, the accuracy and precision of deep-tissue temperature monitoring at the sternum and forehead was sufficient for clinical use.

Abstract
We tested the hypothesis that premedication with i.m. midazolam decreases core temperature dose-dependently. We studied six male volunteers, in random order, on 3 days: (1) no midazolam administration (control day), (2) midazolam 0.025 mg kg-1 i.m., (3) midazolam 0.075 mg kg-1 i.m. On the first day, subjects were maintained alert during a 30-min control period. On the second and third days, midazolam 0.025 or 0.075 mg kg-1 was administered i.m. Core temperatures were measured at the right tympanic membrane. Four adhesive skin surface probes were fixed on the chest, upper right arm, lateral calf and thigh. Finger tip perfusion was evaluated using forearm minus fingertip and calf minus toe, skin surface temperature gradients. Thirty minutes after midazolam i.m., the level of sedation in the volunteers was assessed. Peripheral venous blood was obtained immediately after the assessment of the level of sedation. Tympanic membrane temperatures after administration of midazolam 0.075 mg kg-1 i.m. were significantly lower than those on the control and midazolam 0.025 mg kg-1 i.m. days at 20 and 30 min. The decreases in tympanic membrane temperatures at 30 min after midazolam i.m. became larger as the volunteers were more deeply sedated. i.m. midazolam produced a concentration-dependent decrease in tympanic membrane temperature at 30 min after midazolam 0.025 and 0.075 mg kg-1 i.m. We conclude that midazolam impaired tonic thermoregulatory vasoconstriction, allowing core-to-peripheral heat redistribution in a dose-dependent manner after i.m. administration.

Abstract
PURPOSE To compare measurements made with four infrared tympanic thermometers (Genius, Thermopit, Quickthermo, and Thermoscan) with those recorded from thermocouples positioned in the contralateral ear. METHODS Four tympanic thermometers were evaluated in 50 healthy volunteers (12 female and 38 male). Temperatures were measured, in random order, at the right tympanic membrane four times and the highest temperature was considered to be the true value measured by each thermometer. The control temperature was measured at the left tympanic membrane using Mon-a-Therm thermocouples. RESULTS The tympanic membrane temperature measured by Genius correlated best with the Mon-a-therm measurement (TM) (r = 0.74). The tympanic membrane temperatures measured by Thermopit, Quickthermo, and Thermoscan correlated moderately with TM (r = 0.56, 0.63, and 0.58, respectively). Mean differences between TM and each temperature (TG, TTP, TQ, and TTS) were -0.3, 0.73, 0.42, and -0.3 degrees C, respectively. Likewise standard deviations were 0.33, 0.37, 0.35, and 0.35. CONCLUSION We conclude that all but the Thermopit (TTP) are similarly useful for the management of patients during anaesthesia.

Abstract
To clarify the mechanism of brain impairment in Machado-Joseph disease (MJD), we measured the cerebrospinal fluid (CSF) levels of substance P in 7 patients (mean age 45.7 +/- 12.09 years) with this disease. Four patients had type I and three had type II disease. Findings were compared with those obtained in 14 age-matched controls, 8 patients with Parkinson's disease, 7 patients with multiple system atrophy, and 6 patients with myopathy. The CSF level of substance P was significantly (p = 0.0000) lower in the patients with MJD, being 44.5% of the control value. However, the mean CSF levels of substance P in the patients with Parkinson's disease, multiple system atrophy, or myopathy did not differ significantly from that in the control subjects. The alteration in the CSF level of substance P may be related to the neurological impairment observed in MJD.

Abstract
We designed mutant lysozymes with N-glycosylation signal sequences (Asn48-Gly49-Thr-50 and Asn87-Ile88-Thr89) by substituting Asp to Asn at positions 48 and 87. When these mutant lysozymes were expressed by using yeast (Saccharomyces cerevisiae) in Burkholder minimum medium, N-glycosylation occurred in both lysozymes. The mutant lysozyme with the oligosaccharide at Asn87 showed a similar character to a reported polymannosyl lysozyme [Nakamura, Takasaki, Kobayashi, and Kato (1993) J. Biol. Chem. 268, 12706-12712; Kato, Takasaki, and Ban (1994) FEBS Lett. 355, 76-80]. As judged from the thermodynamic stabilities of the lysozymes obtained by the guanidine hydrochloride denaturation method, the oligosaccharide-bearing mutant lysozymes were more stable by 0.4-1.6 kcal/mol than the corresponding unglycosylated lysozymes. Therefore, it is suggested that the introduction of an N-glycosylation signal sequence into a protein is an effective means to increase the stability of the protein.

Abstract
To identify the metabolic alterations related to mitochondrial functions in Machado-Joseph disease (MJD), we analyzed the cerebrospinal fluid (CSF) levels of lactate, pyruvate, and citric acid cycle intermediates by high performance liquid chromatography (HPLC) in 7 Japanese patients with that disease and then measured some mitochondrial enzymes. Their mean age was 46 years. Diseased controls were matched by age to the patients studied. The CSF level of lactate was significantly elevated, pyruvate was significantly decreased, and the lactate/pyruvate (L/P) ratio was significantly elevated in the patients with MJD. There were no significant differences of citric acid cycle intermediates of the CSF between the patients and the controls. We measured the native and dichloroacetate (DCA)-activated pyruvate dehydrogenase complex (PDHC) activities, and mitochondrial electron transport activities in 3 patients with MJD, and found these activities to be normal. Therefore, the increased CSF lactate, increased lactate/pyruvate ratio, and decreased pyruvate may reflect the decreased regional cerebral blood flow rather than metabolic derangement of the mitochondria.

Abstract
We report the anesthetic management of a patient with cardiac sarcoidosis. Cardiac sarcoidosis is characterized by a high incidence of complete atrioventricular block, right bundle branch block, and ventricular arrhythmias. Cases of sudden death during stable cardiac function have been reported. Therefore, careful anesthetic management is necessary. The patient was premedicated with scopolamine, intramuscularly. Before the induction, he received lidocaine, propranolol, and pentazocine, intravenously. Anesthesia was induced with midazolam and vecuronium, and the trachea was intubated. Anesthesia was maintained with nitrous oxide, sevoflurane in oxygen. Anesthetic method adapted to prevent severe complications including sudden death resulted in good condition of the patient during the perioperative period.

Abstract
We determined the pKa values of acidic residues in hen lysozyme by comparing the pH dependency of stability between wild type and mutant lysozymes in which a negative charge is eliminated. In the comparison of the stability between wild type and a mutant lysozyme, the difference in pH titration curve between them could be expressed as a two-state process involving protonation of a single acidic residue. The results strongly indicated that the Aune and Tanford theory of protein denaturation [Aune, K.C. and Tanford, C. (1969) Biochemistry 8, 4579-4585] is applicable to protein stability in solution. On the other hand, the pKa values of acidic residues in the presence of low (5 mM) or high (400 mM) salt concentration were determined by means of two-dimensional NMR. We found that the pKa values obtained from the pH dependency of stability were close to those from the NMR experiment under the high salt condition. Moreover, by comparing pKa values at high salt and low salt concentrations, we could evaluate the dependency of two electrostatic interactions (salt bridge and charge-helix dipole interaction) on salt concentration.

Abstract
We performed a double-blind, placebo-controlled, crossover trial of sulfamethoxazole-trimethoprim (S-T) in 8 patients with Machado-Joseph disease (MJD), and measured the blood and cerebrospinal fluid levels of biopterins, biogenic amines or metabolites, and folate. The clinical results were as follows; mild improvements of hyperreflexia of knee jerks and of rigospasticity of the legs during S-T treatment period. In addition, S-T significantly reduced the times of 8 motor activities on the timed tests. The biochemical results showed that basal levels of all biopterins and homovanillic acid in the cerebrospinal fluid (CSF) were reduced to less than half the levels of those of controls with other neurological diseases. After S-T treatment, total and oxidized form of biopterins in the CSF increased significantly. Therefore, S-T may be effective to neurologic deficits through its mechanism of increasing the level of brain biopterins.

Abstract
We measured the cerebrospinal fluid (CSF) levels of beta-endorphin in 7 Japanese patients with Joseph disease and compared them with control values. The 7 patients included 4 with type I and 3 with type II disease; their mean age was 45.7 +/- 12.09 years. Diseased controls were matched in age to the patients studied. In these patients, CSF beta-endorphin level was significantly lower than in the controls (40% of normal values). An alteration in CSF beta-endorphin level may explain some of the neurological impairment found in Joseph disease.

Abstract
The dystrophin gene was examined by PCR analysis in 30 Japanese patients with Becker muscular dystrophy (BMD). Fifteen PCR of these patients had exon deletion, generally, less than three exons. Muscle biopsies were also performed in 20 BMD patients (10 with sequence deletions, and 10 without detectable sequence deletions) in order to correlate PCR findings with immunoblot and immunostaining data. A patchy, heterogeneous membrane immunostaining pattern of reduced intensity was found, irrespective of the presence or absence of deletions. Immunoblotting studies demonstrated dystrophin of low molecular mass and quantity in BMD patients with deletion mutations, while a low quantity of dystrophin with an apparent wild type molecular mass was observed in nearly half the BMD patients without detectable deletions. However, these dystrophins were also found to have slightly abnormal molecular masses when the standard electrophoresis time was prolonged. This suggests that immunoblots and PCR data correlate well in patients with BMD. Additionally, it is suggested that immunoblot assays can detect abnormalities in dystrophin in the absence of detectable PCR deletions.

Abstract
A man, aged 52, is reported to show (1) adult onset, (2) progressive orofacial dyskinesia and choreic movements of the extremities, (3) tongue biting, (4) denervation of the peripheral nerves, (5) acanthocytosis, and (6) increased serum creatine kinase, which are characteristic of chorea-acanthocytosis. The Kell blood group examination on erythrocytes disclosed that the propositus had McLeod phenotype, and his mother and one of his sisters were carriers of the McLeod phenotype. Thus, he was diagnosed as having McLeod syndrome. A criterion of exclusion of McLeod phenotype on erythrocytes should be added to the diagnostic criteria of chorea-acanthocytosis. Moreover, chronic neurogenic changes instead of myogenic changes were electromyographically and histopathologically verified in the muscle.

Abstract
Hypertrophic obstructive cardiomyopathy (HOCM) is characterized by asymmetric hypertrophy of the intraventricular septum, causing intermittent obstruction of the left ventricular outflow tract. General principles of management for HOCM include maintenance of adequate preload and afterload, and avoidance of tachycardia and increased myocardial contractility. A 57 year old male for subtotal gastrectomy and gastrojejunostomy received epidural anesthesia with epidural high dose fentanyl (0.5 mg) and 0.5% isoflurane with N2O and oxygen. Blood pressure and heart rate decreased mildly but were stable during the operation and during the recovery period from anesthesia without any complaints of pain. The results suggest that epidural high dose fentanyl anesthesia is a good method for patients with HOCM.

Abstract
To elucidate the usefulness in prediction of hypersensitive reactions of L-asparaginase (L-asp), anti-L-asp IgG antibody was measured by two kinds of enzyme-linked immunosolvent assay (ELISA) with improved microplate method and original immunobeads method. The correlation coefficient of both methods matched very well (R = 0.949). Nine out of the 10 patients who were treated with L-asp for the first time showed the elevation of the anti L-asp IgG antibody and returned to normal range within 9 months thereafter. Twenty-two out of 26 patients (84.6%) who had ever developed hypersensitive reactions showed the positive anti-L-asp antibody. There was no positive correlation between the anti-L-asp titer and the severity of the hypersensitive reactions. We concluded that the ELISA with microplate was simple and useful methods to determined the anti-L-asp IgG antibody.

Abstract
Saturated very long-chain fatty acids in erythrocyte membranes, blood plasma, and mononuclear cells were studied in 4 patients with childhood-adolescent adrenoleukodystrophy and 4 patients with adult adrenoleukodystrophy and 19 normal control subjects by using high-performance liquid chromatography. Ratios of C26:0 to C22:0 in mononuclear cells, erythrocyte membranes, and blood plasma in patients with childhood-adolescent and adult adrenoleukodystrophy were significantly higher than in normal control subjects. Furthermore, ratios of C26:0 to C22:0 in mononuclear cells were significantly higher in patients with childhood-adolescent adrenoleukodystrophy than in patients with adult adrenoleukodystrophy, whereas there was no significant difference in the ratios in erythrocyte membranes and blood plasma between the two groups of patients with adrenoleukodystrophy. These results suggest that there is a correlation between phenotype and ratio of C26:0 to C22:0 within mononuclear cells in patients with adrenoleukodystrophy.

Abstract
Phospholipid class, peak profile of each phospholipid class, loosely bound fatty acids, covalently (tightly) bound fatty acids of the erythrocyte membranes, and plasma fatty acids were investigated using high-performance liquid chromatography in six patients with chorea-acanthocytosis and 14 age- and sex-matched normal control subjects. Additionally, six patients with Huntington's disease were included as disease control subjects in the study of covalently bound fatty acids. Study of covalently (tightly) bound fatty acids in erythrocyte membrane proteins after alkaline hydrolysis, hitherto undescribed in chorea-acanthocytosis, revealed that palmitic acid (C16:0) was significantly increased and stearic acid (C18:0) was decreased in the patients with chorea-acanthocytosis. Analyses for total covalently bound fatty acids disclosed that palmitic and docosahexaenoic (C22:6) acids were increased and stearic acid was decreased in chorea-acanthocytosis. Phospholipid class (phosphatidylcholine, phosphatidylethanolamine, sphingomyelin, and phosphatidylserine) and peak profile of each phospholipid class from the erythrocyte membranes did not differ between the patients with chorea-acanthocytosis and the control subjects. Of the loosely bound fatty acids, linoleic acid (C18:2) was significantly decreased in those with chorea-acanthocytosis, which seemed to be nonspecific.

Abstract
A Japanese male with juvenile Sandhoff disease is described. The patient was a product of full-term normal pregnancy from non-consanguineous parents. Since age 10, he developed progressive dysarthria and proximal muscle atrophy and weakness. Mental deterioration and cerebellar ataxia are also noted since the age of 20. On neurological examination at age 35, he showed decreased mentality (IQ 62), marked atrophy and weakness of proximal muscles, cerebellar ataxia and increased deep tendon reflexes. Brain CT scans revealed moderate to marked atrophy of cerebellum. Giant MUP, fasciculation potentials and positive sharp waves were observed on EMG examination. Biopsied sural nerve showed markedly decreased myelinated fibers. Hexosaminidase A and B activities in leukocytes and cultured fibroblasts were about 10% of normal values, while other lysosomal enzyme activities were within normal range. Rectal biopsy demonstrated lamellar inclusion bodies in submucosal ganglion cells. This is the first Japanese patient with juvenile Sandhoff disease presenting symptoms similar to motor neuron disease and cerebellar degeneration.

Abstract
We studied the very-long-chain fatty acids of blood plasma, erythrocyte membranes and lymphocytes in 4 adrenoleukodystrophy patients, 5 adrenoleukodystrophy obligate carriers, 12 normal controls and 81 patients with various neurological disorders by high-performance liquid chromatography and compared the reliabilities in the diagnosis of adrenoleukodystrophy of these 3 components of peripheral blood. Of 81 patients with various neurological disorders, 2 myotonic dystrophy and 2 spinocerebellar degeneration patients showed increased ratios of C26:0 to C22:0 in erythrocyte membranes, but not in blood plasma and lymphocytes. None of the 12 normal controls showed increased ratios of C26:0 to C22:0 in erythrocyte membranes, blood plasma and lymphocytes. These results suggest that fatty acid analysis for the diagnosis of adrenoleukodystrophy is more reliable when blood plasma and lymphocytes are used than when erythrocyte membranes are used.

Abstract
A 62-year-old male Japanese, a heavy drinker for his last 40 years, was admitted to our hospital because of unstable gait of acute onset. Despite large doses of thiamine injection, his condition rapidly worsened with confusion, and died 15 days after the onset. During the deteriorating course, a series of Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) scans were taken of the brain, which revealed progressive multifocal involvement in the corpus callosum; Marchiafava-Bignami disease was suggested. To the authors' best knowledge, there have been no MRI examinations conducted from so early a stage of this disease on. MRI scanning proves to be a highly useful tool for early diagnosis of Marchiafava-Bignami disease.

With a newly devised method of high-performance liquid chromatography (HPLC), we scrutinized lipid extraction of very-long-chain fatty acids of cultured skin fibroblasts from obligate (n = 4) and possible (n = 3) carriers for adrenoleukodystrophy (ALD) in order to establish the best method to detect a carrier for the ALD gene. All four methods (total esterified fatty acids, total fatty acids with acetonitrile-HCl, total fatty acids with methanolic-HCl, and triacylglycerol fraction) were applicable to carrier detection, but from the standpoint of simplicity and sensitivity, the method using total fatty acids with acetonitrile-HCl seemed to be the best. This is the first study of ALD carrier detection in which cultured skin fibroblasts are investigated using HPLC as an analytical method.
