Abstract
Acute encephalopathy with biphasic seizures and reduced diffusion (AESD) is characterized by biphasic seizures following febrile viral infections and delayed reduced diffusion of the cerebral white matter on magnetic resonance imaging (MRI) diffusion-weighted imaging (DWI) (bright tree appearance, BTA). However, hypoxic encephalopathy with biphasic seizures and AESD-mimicking imaging findings has not been reported. We report a case of hypoxic encephalopathy due to suffocation with concomitant biphasic seizures and BTA, mimicking AESD. On day 1, a healthy 5-month-old girl was found face down with decreased breathing and a deteriorating consciousness level, suggesting a brief resolved unexplained event (BRUE). Electroencephalography (EEG) revealed periodic epileptic discharges, suggesting possible nonconvulsive status epilepticus. Despite improvements in consciousness level and EEG abnormalities on day 2, her consciousness level deteriorated again with generalized tonic-clonic seizures on day 3, and a head MRI-DWI revealed restricted diffusion predominantly in the subcortical areas, suggesting BTA. Treatment for acute encephalopathy resolved the clinical seizures and EEG abnormalities. Persistence of abnormal EEG, reflecting abnormal excitation and accumulation of neurotoxic substances caused by hypoxia, may have contributed to the development of AESD-like findings. As hypoxic encephalopathy causes AESD-like biphasic seizures, monitoring consciousness level, seizure occurrence, and EEG abnormalities even after acute symptoms have temporarily improved following hypoxia is essential.

Abstract
Background Sinus pericranii is a rare cranial venous malformation resulting in a subcutaneous mass due to abnormal communication between intracranial and subperiosteal/interperiosteal veins. To date, to the best of our knowledge, there are no reports of sinus pericranii associated with syntelencephaly, a subtype of lobar holoprosencephaly. We herein report a case of sinus pericranii associated with syntelencephaly. This report can provide us better understanding of the etiology of sinus pericranii, the potential risks, and the treatment options for these patients. Case presentation A 2-year-4-month old female patient who received the diagnosis of syntelencephaly as a neonate presented with a subcutaneous mass in the parietal region. The mass was soft, nonpulsatile, 3 × 2 cm in size, and showed enlargement in the lying position. Color cranial Doppler ultrasound, head magnetic resonance imaging (MRI), and cerebral angiography revealed a dilated vessel passing through the parietal bone and forming a communication between the superior sagittal sinus and scalp veins. Based on these findings, sinus pericranii was diagnosed. The head MRI also showed coronal craniosynostosis, a tight posterior fossa. At age 2 years and 7 months, the patient underwent a transection of the sinus pericranii and the mass resolved without any complications or recurrences for more than 2.5 years to date. Conclusion Sinus pericranii is a rare cranial and venous malformation sometimes accompanied by brain malformations or craniosynostosis that may become more apparent as the brain and skull develop. Since this condition can be complicated by intracranial hemorrhage and sinus thrombosis, early detection is necessary to determine the treatment options. Physicians should be alert to the possibility of this condition if they observe a soft cranial mass that appears to decrease in size in the sitting position and bulge in the lying position.

Abstract
Sphenoid wing dysplasia (SWD) is a common orbital complication of neurofibromatosis type 1 (NF1). However, enophthalmos associated with SWD is extremely rare, and details of its natural history are unclear. We present the case of a 14-year-old boy with an early childhood diagnosis of NF1 presenting with left blepharophimosis and enophthalmos for several months. Imaging demonstrated enlargement of the left lateral SWD, progression of the posteromedial deviation of the orbital contents, and sphenoid/ethmoid sinus deformation due to left temporal lobe compression over 12 years. Two characteristic changes were revealed on imaging: enlargement of the middle cranial fossa and deformation of the sphenoid/ethmoid sinuses. The orbital contents were compressed by the intracranial pressure of the temporal lobe and were displaced posteromedially into the space created by the deformed sphenoid/ethmoid sinuses. Because orbital symptoms can gradually become apparent over years with the progression of SWD and skeletal growth, long-term follow-up of orbital symptoms is recommended in patients with NF1.

Abstract
Here, we present a comprehensive protocol to analyze the roles of disease-related genes in synaptic transmission. We have developed a pipeline of electrophysiological techniques and combined these with optogenetics in the medial prefrontal cortex of mice. This methodology provides a cost-effective, faster, and easier screening approach to elucidate functional aspects of single genes in several regions in the mouse brain such as a specific layer of the mPFC. For complete details on the use and execution of this protocol, please refer to Nagahama et al. (2020) and Sacai et al. (2020).

Abstract
Introduction Congenital complete atrioventricular block (CCAVB) associated with congenital chylothorax is a rare finding that has been reported in only one case in the literature. We report here the case of an infant with CCAVB complicated by congenital chylothorax. Patient Report We present the case of a male neonate with a birth weight of 2114 g. Fetal bradycardia and right pleural effusion were detected at gestational age of 22 weeks. Maternal serum levels of anti-Sjögren's-syndrome-related antigen A autoantibody were high (4840 U/mL). The neonate was delivered at gestational age of 33 weeks; a temporary external pacemaker was placed immediately after birth that resulted in an improved cardiac output. Milk-colored pleural effusion increased in volume together with the initiation of breast milk feeding. Lymphocytosis and high triglyceride levels in the pleural fluid led to the diagnosis of chylothorax. The pleural effusion resolved in response to prednisolone, octreotide, and total parenteral nutrition. Discussion The causal relationship between CCAVB and congenital chylothorax can be explained by considering the damage to the lymphatic vessels secondary to inflammation due to maternal autoantibodies and venous congestion due to bradycardia. Conclusion In any case of CCAVB associated with atypical pleural effusion, one must consider the possibility of congenital chylothorax.

Abstract
INTRODUCTION Jacobsen syndrome (JS) is caused by a deletion at the terminus of the long arm of chromosome 11. There are few reports of JS associated with cerebral white matter abnormalities (WMA), and the etiology, pathophysiology, and time-dependent changes in WMA with JS still remain unclear. CASE REPORT The patient was a 2-month-old female with several morphological anomalies, including trigonocephaly, ectropion, flat nasal bridge, low-set ears, and sparse eyebrows. Chromosome analysis (G-banding karyotyping) of 46,XX,del(11)(q23.3) led to the diagnosis of JS. Head MRI performed at age 9 months indicated diffuse WMA with hyperintense signals on T2-weighted imaging. MRI at age 2.5 years demonstrated a decrease in the WMA and progressive myelination. DISCUSSION These findings suggested that the WMA in the present patient were due to chronic white matter edema associated with a deletion in the 11q terminal region of HEPACAM/GlialCAM, a causative gene for megalencephalic leukoencephalopathy with subcortical cysts type 2B (MLC2B). As with some of MLC2B patients, the WMA in the present patient improved over time. The present report is the first to document dramatic changes in WMA in JS visualized by serial MRI examinations from the neonatal period through early childhood. CONCLUSION The findings of the present study suggested that WMA in JS are due to chronic white matter edema associated with HEPACAM/GlialCAM deletion and show gradual improvement over time, as seen in some MLC2B patients.

Abstract
Most cardiac rhabdomyomas with tuberous sclerosis (TS) are asymptomatic and spontaneously regress. However, some cases require surgical intervention due to arrhythmia and severe obstruction of cardiac inflow or outflow. We report herein a neonatal case of giant cardiac rhabdomyomas with TS and insufficient pulmonary blood flow from the right ventricle. Lipoprostaglandin E1 was necessary to maintain patency of the ductus arteriosus. We used everolimus, a mammalian target of rapamycin inhibitor, to diminish the cardiac rhabdomyomas. After treatment, the rhabdomyomas shrank rapidly, but the serum concentration of everolimus increased sharply (maximum serum trough level: 76.1 ng/mL) and induced complications including pulmonary hemorrhage, liver dysfunction, and acne. After the everolimus level decreased, the complications resolved. Everolimus may be a viable treatment option for rhabdomyomas, but its concentration requires close monitoring to circumvent complications associated with its use.

Abstract
Background Congenital diaphragmatic hernia (CDH) is fatal in severe cases of pulmonary hypoplasia. We experienced a fatal case of pulmonary hypoplasia due to CDH, thoracic myelomeningocele (MMC), and thoracic dysplasia. This constellation of anomalies has not been previously reported. Case Report A male infant with a prenatal diagnosis of thoracic MMC with severe hydrocephalus and scoliosis was born at 36 weeks of gestation. CDH was found after birth and the patient died of respiratory failure due to pulmonary hypoplasia and persistent pulmonary hypertension of the newborn at 30 hours of age despite neonatal intensive care. An autopsy revealed a left CDH without herniation of the liver or stomach into the thoracic cavity, severe hydrocephalus, Chiari malformation type II, MMC with spina bifida from Th4 to Th12, hemivertebrae, fused ribs, deformities of the thoracic cage and legs, short trunk, and agenesis of the left kidney. Conclusion We speculate that two factors may be associated with the severe pulmonary hypoplasia: decreased thoracic space due to the herniation of visceral organs caused by CDH and thoracic dysplasia due to skeletal deformity and severe scoliosis.

Abstract
Ataxia-telangiectasia is a chronic progressive disorder affecting the nervous and immune systems, caused by a genetic defect in the ATM protein. Clasmatodendrosis, a distinct form of astroglial death, has rarely been reported in ataxia-telangiectasia. Neuropathology of our patient disclosed diffuse edema of the cerebral and cerebellar white matter with prominent clasmatodendrosis, implicating ATM in the regulation of astroglial cell death.

Abstract
To realize a novel vacuum-atmosphere interface that does not require a large differential pumping system, a robust cascade arc discharge source called a plasma window is constructed and tested for long-term operation. By modifying a test plasma with a direct current discharge, a vacuum interface with a high gas pressure ratio of 1/407 between the discharge and expansion sections is demonstrated for currents as high as 20 A. No significant damage to the electrodes is observed during the operation. Analysis of the visible emission spectra reveals that a stationary, stable argon plasma having a temperature of 1 eV and a density of 1.5 × 10(16) cm(-3) is generated in the plasma channel.

Abstract
We measured interleukin-6 (IL-6) concentrations from 48 malignant pleural effusions by an enzyme immunoassay and found a marked heterogeneity of the concentrations. The histological type of the malignant cells and total counts or differentials of the cells in effusions could not account for the heterogeneity. We newly established five malignant cell lines and found that the amounts of IL-6 produced by them were well correlated with IL-6 concentrations of the effusions from which these lines were derived (r=0.96; p<0.01). These results suggest that a marked heterogeneity of IL-6 concentrations in malignant effusions reflects the differential production of IL-6 by malignant cells in pleural space.

Abstract
A custom developed (6)Li glass scintillator (APLF80+3Pr) for down-scattered neutron diagnostics in inertial confinement fusion experiments is presented. (6)Li provides an enhanced sensitivity for down-scattered neutrons in DD fusion and its experimentally observed 5-6 ns response time fulfills the requirement for down-scattered neutron detectors. A time-of-flight detector operating in the current mode using the APLF80+3Pr was designed and its feasibility observing down-scattered neutrons was demonstrated. Furthermore, a prototype design for a down-scattered neutron imaging detector was also demonstrated. This material promises viability as a future down-scattered neutron detector for the National Ignition Facility.

Abstract
7660 Background: Nedaplatin (CDGP) is a cisplatin derivative developed in Japan. In non-small cell lung cancer (NSCLC), its response as monotherapy has been reported to be 20.5%, while when used in combination with vindesine, its efficacy is similar to cisplatin (CDDP). With respect to adverse effects, it causes less nausea/vomiting and nephrotoxicity compared to CDDP. By these data, we conducted a phase II study of combination treatment with CDGP and docetaxel (TXT) in advanced NSCLC. Methods: Forty six patients (Male/Female 39/7, median age 65 years (40–79), IIIB/IV 20/26) were enrolled from March 2004 to March 2006. Eligibility criteria included signed informed consent, age over 20 and under 80, measurable disease, ECOG PS 0–1, adequate bone marrow reserve, no previous chemotherapy or radiotherapy, and life-expectancy of at least 12 weeks. Treatment consisted of 80 mg/m2 CDGP and 60 mg/m2 TXT on day one with about 1,000 ml of hydration every 3–4 weeks. Results: One hundred and forty four cycles were given to 46 pts (mean cycles 3.1) and the mean dosages actually administered were 75.5±6.1 mg/m2 for CGDP and 57.7±4.6 mg/m2 for TXT. An over all response rate was 52.2% (squamous cell carcinoma 66.7%, adenocarcinoma 44.0%), median survival time was 12 months and 1-year survival rate was 50%. NCI-CTC grades 3–4 leukopenia, neutropenia, nausea/vomiting and appetite loss occurred in 44 (29.2%), 50 (34.7%), 5 (3.5%), 6 (4.2%) cycles, respectively. There was no grade 3–4 anemia, thrombocytopenia and neuropathy. Conclusions: This combination of chemotherapy was well tolerated, and its activity and survival for advanced NSCLC were acceptable. The update data will be presented at the meeting. No significant financial relationships to disclose.

Abstract
BACKGROUND AND AIM Interleukin (IL) 17 is a cytokine which exerts strong proinflammatory activities. In this study we evaluated changes in IL-17 expression in the inflamed mucosa and in the serum of patients with inflammatory bowel disease (IBD). METHODS Tissue samples were obtained endoscopically or surgically from patients with ulcerative colitis (UC) (n=20), Crohn's disease (CD) (n=20), infectious colitis (n=5), ischaemic colitis (n=8), and normal colorectal tissues (n=15). IL-17 expression was evaluated by a standard immunohistochemical procedure. Serum IL-17 levels were determined by ELISA. IL-17 mRNA expression was analysed by reverse transcriptase-polymerase chain reaction. RESULTS IL-17 expression was not detected in samples from normal colonic mucosa, infectious colitis, or ischaemic colitis. In the inflamed mucosa of active UC and CD patients, IL-17 expression was clearly detectable in CD3(+) T cells or CD68(+) monocytes/macrophages. The average number of IL-17(+) cells was significantly increased in active UC and CD patients compared with inactive patients. IL-17 mRNA expression was not detected in normal mucosa but was detectable in the mucosa from active UC and CD patients. IL-17 was not detected in the sera from normal individuals, infectious colitis, or ischaemic colitis patients but IL-17 levels were significantly elevated in IBD patients. CONCLUSIONS IL-17 expression in the mucosa and serum was increased in IBD patients. It is likely that IL-17 expression in IBD may be associated with altered immune and inflammatory responses in the intestinal mucosa.

Abstract
We report two cases of periosteal chondroma of the rib, an extremely rare entity. The first case involved a 5-year-old boy who was admitted with pain and swelling around his left fifth rib. Surgery was performed in May 1999, and an 8 x 6 x 5 mm tumor was resected with the fifth rib. The second case involved a 39-year-old man with a 2-month history of cough who was referred to our department after a coin lesion had been detected on a chest roentgenogram. Physical examination on admission did not reveal any pain or tenderness. The rib tumor was resected along with the fourth rib by video-assisted thoracoscopic surgery and minithoracotomy in February 2000. The tumor was well encapsulated and consisted of an elastic hard mass measuring 22 x 15 x 13 mm. Both patients had an uneventful postoperative course and have remained well with no evidence of recurrence. Our review of the literature revealed only six previously documented cases of periosteal chondroma of the rib.

Abstract
BACKGROUND MUC4 has been cloned from tracheobronchial mucosa cDNA and reportedly is highly expressed in some human malignancies, including lung carcinoma. However, little is known about molecular and biologic characteristics. The authors analyzed expression levels of MUC4 mRNA and protein in lung carcinoma cells and analyzed the immunogenicity of this mucin. METHODS Nine cultured lung carcinoma cell lines and 29 tumor samples from patients with lung carcinoma were examined by Northern hybridization for MUC4 mRNA expression and by flow cytometry or an immunohistochemical staining for its protein expression. Sera from the patients were examined for their reactivity with MUC4 by enzyme-linked immunosorbent assay. RESULTS Forty-four percent of the cell lines and 72% of the tumor samples showed high levels of MUC4 mRNA expression. Although MUC4 protein was not detected in any live carcinoma cell lines by flow cytometry using rabbit antisera reactive with the MUC4 core, pretreatment with paraformaldehyde and sialidase resulted in successful detection of the protein in 50% of the cell lines. An immunohistochemical study revealed that 67% of the tumors exhibited MUC4 protein expression without any digestion. In 29% of the patients, high levels of anti-MUC4 immunoglobulin M or immunoglobulin G were detected. CONCLUSIONS MUC4 protein expression was elevated in lung carcinoma tissues because of the increase in its mRNA expression and deglycosylation on its core. This mucin is sufficiently immunogenic to elicit humoral and cellular immunity specific for MUC4 in patients with malignant disease. MUC4 is expected to be useful as a target antigen in immunotherapy for patients with carcinoma of the lung.

Abstract
We report three cases of patients exhibiting a false elevation of serum free triiodothyronine (FT3) as a result of a cross-reaction with diclofenac. The first case is a 66-yr-old woman with a long history of rheumatoid arthritis (RA). The patient was receiving diclofenac for the treatment of her RA. The patient was subsequently diagnosed as having thyroid papillary adenocarcinoma and received a subtotal thyroidectomy. After the operation, the patient exhibited postoperative hypothyroidism except for a gradual elevation of FT3. The other two patients also exhibited an elevated serum FT3 level after the administration of diclofenac. Serum FT3 levels in these patients decreased to normal or below normal after diclofenac administration was discontinued. In the first case, the elimination of immunoglobulin from the sera using polyethylene glycol precipitation did not reduce the FT3 level. In our hospital, Vitros ECi (enhanced chemiluminescence enzyme immunoassay) system and Vitros FT3 kit were used for FT3 assay. The patient's FT3 levels were normal or below normal when they were measured using other FT3 kits. FT3 was also detected when diclofenac was dissolved in a phosphate buffered saline. Therefore, we concluded that a cross-reaction between FT3 and diclofenac was the mechanism causing the false elevation of FT3 in these patients.

Abstract
UNLABELLED The aim of the study was to investigate the increase in myocardial (99m)Tc-methoxyisobutylisonitrile (sestamibi) retention in humans during pharmacologic vasodilation. METHODS For calculation of the increase in (99m)Tc-sestamibi retention during hyperemia, baseline and adenosine triphosphate (ATP)-induced hyperemic stress sestamibi studies were performed using a same-day rest-stress protocol. On the injection of sestamibi, left ventricular dynamic data were obtained for 90 s. The increase in sestamibi retention from baseline to hyperemia was calculated by the formula [abstract: see text] where Cm(h)(t) and Cm(b)(t) are myocardial counts on the tomographic image, and Cb(b)(tau) and Cb(h)(tau) are the left ventricular blood-pool counts during the first transit of sestamibi at baseline and during hyperemia, respectively. Coronary flow increase during intravenous ATP stress was measured using intracoronary Doppler flow guide wire and compared with the scintigraphic results of 28 measurements in 22 patients. RESULTS Sestamibi retention increased as coronary flow velocity increased but plateaued at >2.5-3 times baseline flow velocity. The relationship between the increase in sestamibi retention (Y) and the increase in flow (X) is expressed as follows: Y = 0.44 + 0.60X - 0.068X(2) (r = 0.82). CONCLUSION In humans, the increase in (99m)Tc-sestamibi myocardial retention underestimates coronary flow reserve, particularly at high flow rates. Knowledge of these tracer retention characteristics will contribute to a more comprehensive understanding of the manner and interpretation of stress sestamibi imaging.

Abstract
Barotrauma is well known to be a relatively common complication of high-frequency jet ventilation (HFJV); however, the occurrence of reexpansion pulmonary edema (REPE) is extremely rare. We report herein a case of REPE caused by difficulties encountered with anesthesia using HFJV during video-assisted thoracic surgery (VATS) for a spontaneous pneumothorax. We believe the rapid increase in pressure in the lung after degassing for VATS resulted in REPE as well as typical barotrauma.

Abstract
AIMS Granzyme B and perforin, which are contained in cytotoxic granules produced by tumour-infiltrating immune cells, have been reported to be involved in suppression of cancer progression. In this study, the relationship between expression of these molecules and clinical factors in cancer patients was studied. METHODS Tumour tissue obtained from 23 breast cancer patients and 13 lung cancer patients were examined for expression of granzyme B, perforin and B7-1, using an immunohistochemical technique. The percentage of cells positive for expression of these molecules and the clinical status of each case were compared. RESULTS Both granzyme B and perforin were distributed in the cytoplasm of cancer cells in many cases rather than in tumour-infiltrating lymphocytes. This was observed even in cases of early-stage tumours. In both breast and lung cancer patients, the percentage of cells positive for granzyme B and perforin expression was inversely correlated with the status of regional node metastasis. A competitive RT-PCR analysis confirmed that the expression of mRNA from these molecules extracted from the tumours was consistent with the immunohistochemical results. CONCLUSION Granzyme B and perforin may play a role in the suppression of nodal metastasis of cancer cells in breast and lung cancers.

Abstract
A 55-year-old moderately obese man who was admitted to a local hospital following a traffic accident reported having experienced an episode of sharp and sudden pleuritic pain in the left anterior lower chest 2 days earlier. A computed tomographic scan on admission demonstrated a nonhomogeneous mass in the anterior left side of the chest, abutting the left cardiac margin, and a left-sided pleural effusion. As a mediastinal tumor was suspected, he was referred to our hospital for investigation and treatment. An exploratory thoracotomy was performed by video-assisted thoracic surgery (VATS) about 3 weeks later, which revealed a firm, yellowish mass on the oral side of the pericardial fat pad, adhering to the anterior chest wall. The mass was easily removed. The resected specimen consisted of a lobulated fragment of adipose tissue measuring 5.0 x 3.5 x 2.0 cm, and the final pathologic diagnosis was pericardial fat necrosis. The patient had an uneventful postoperative recovery and has remained free of symptoms for 10 months since his operation. Pericardial fat necrosis remains a rare clinical entity. Surgical excision by VATS achieves symptomatic cure and probably continues to be the treatment of choice because of the need to exclude a neoplasm in the differential diagnosis.

Abstract
A 50-year-old healthy woman was scheduled for surgery of the first thoracic vertebral (T 1) hemangioma accompanying rapidly aggravated neurological deficit in three months. Anesthesia was induced with intravenous fentanyl and propofol and maintained with isoflurane-oxygen-air inhalation, followed by propofol infusion combined with sevoflurane inhalation. Following posterior decompression of T 1 with fusion of C 6-T 3, consecutive total spondylectomy of T 1 with anterior fusion of C 7-T 2 was carried out. At the end of surgery, marked edema was noticed on her face, neck and bilateral upper extremities, possibly due to long manipulation around the left jugular angle. Next morning the edema spread to her whole body and the elevation of both diaphragms and the mediastinal expansion were recognized. Mechanical ventilation in the mode of IMV was performed until subsiding of edema on the fifth postoperative day. During this period, hypoxemia was frequently observed in spite of appropriate respiratory support. On the third postoperative day, bronchoscopic bronchial toilet was performed which brought the improvement of blood oxygenation. The occasional administration of furosemide was not effective to reduce general edema, but served for the acceleration of lymphatic drainage after the release of the thoracic duct obstruction and the patient was extubated uneventfully on the sixth postoperative day.

Abstract
We attempted to induce MUC1-specific cytotoxic T lymphocytes (CTLs) by mixed-lymphocyte tumor cell culture (MLTC) using two allogeneic MUC1-positive cancer cell lines, T-47D and MCF7. The induced CTLs exhibited MUC1-specific cytotoxicity 16 days after the initial stimulation. However, these CTLs underwent apoptotic death within 16 days. To examine whether the B7-1 molecule is required for the expansion of the responder cells, a B7-1(+)/MUC1(-) cell line was transfected with MUC1 cDNA, and the resulting transfectant was employed as a stimulator in an autologous MLTC. The CTLs exhibited MUC1 specificity but also continued to propagate. In parallel, autologous dendritic cells (DCs) were added to an MLTC containing peripheral blood lymphocytes (PBLs) and the allogeneic MUC1-positive stimulators. The CTLs demonstrated MUC1 specificity and their number increased. This suggests that the B7-1 molecule is required for rescuing CTLs from MUC1-mediated apoptotic death, but not for the induction of MUC1-specific responsiveness. This strategy to obtain the CTLs efficiently may be useful for adoptive immunotherapy against cancer.

Abstract
BACKGROUND Indications for surgical treatment in advanced lung cancer still remain to be established. METHODS The outcomes of combined resection of adjacent organs in lung cancer were assessed in terms of complications and the invasiveness of surgery, using intraoperative blood loss and operation time as indices. RESULTS In 68 patients undergoing combined resection between 1980 and 1997, the 5-year-survival rates and the incidence of complications and hospital deaths were 24.5%, 52.9%,and 10.3%, respectively. The mean blood loss and operation time were 1,200 ml and 396 minutes. The rares of complications and hospital deaths were significantly higher in the group with 1,000 ml or more blood loss, and in the group with 360 minutes or longer operation time. CONCLUSIONS In terms of the survival rate, invasiveness of surgery, and complications, the pleura and pericardium were the best indications for combined surgery. For the thoracic wall, blood loss was greater and the rates of complications and hospital deaths tended to be higher among T3 cases. Both blood loss and operation time tended to be greater in T4 cases. Indications for surgery need to be carefully determined with respect to curability.

Abstract
A 73-year-old man was hospitalized because of weight loss and fever. Laboratory data showed marked leukocytosis (21,200/mm3), granulocytosis (89.7%), thrombocytosis (47.8 x 10(4)/mm3), increased CRP (15.8 mg/dl), and increased SCC (5.0 ng/ml). Chest X-ray films demonstrated a mass shadow in the right upper lung field. Chest computed tomographic scans revealed a mass shadow 58 mm in diameter with mediastinal pleural invasion in the right S1. Right upper lobectomy and dissection of regional lymph nodes was performed under a diagnosis of lung cancer (squamous cell carcinoma, T3 N0 M0 stage IIB) with concomitant infection. Serum G-CSF was 234 pg/ml pre-operatively and 68.8 pg/ml postoperatively. The cytoplasm of tumor cells stained positively with anti-recombinant human G-CSF monoclonal antibody. No general bacteria or mycobacteria were detected within the specimen. Postoperatively, the patient's white blood cell count, platelet count, and CRP level soon decreased, and the fever disappeared. We diagnosed the disease as G-CSF-producing squamous cell type lung cancer.

Abstract
In a 54-year-old woman with diabetes mellitus, hearing loss, muscle weakness and hypocalcemia, caused by idiopathic hypoparathyroidism, an A to G transition at the nucleotide position of 3243 (A3243G mutation) was found in the mitochondrial DNA from her leukocytes. Clinical features of diabetes mellitus and hearing loss in association with the A3243G mutation are compatible with a diagnosis of maternally inherited diabetes and deafness (MIDD). Although hypoparathyroidism is rarely seen in MIDD, we consider that hypoparathyroidism in this patient is a possible phenotype caused by the A3243G mutation of mitochondrial DNA.

Abstract
STUDY OBJECTIVES There have been many studies on the physical characteristics at the time of contraction of a primary spontaneous pneumothorax (PSP), but it has not been shown when and how such physical characteristics develop. These issues were investigated. PATIENTS AND DESIGN Physical development of 27 male patients with PSP were examined. Their physical records were collected with the patients' permission, and standard curves, estimated from the Japanese nationwide records in the year corresponding to the ages of the patients, were plotted as control values. RESULTS The height of patients was already greater at 6 years of age. It showed a marked increase from 11 to 14 years. The body weight was more than the standard until 9 years, but it became less after age 11, and this difference increased after age 15. Rohrer's index was significantly lower than the standard at all ages, and the difference was particularly large from 11 to 15 years. In the standard group, there was a balance between the annual height and weight gain. In the patient group, annual weight gain was similar to that in the standard group whereas height began to increase 2 years earlier, and as a result, ectomorphy, which was also observed before this age, became marked at this age. CONCLUSIONS The rapid increase in the vertical dimension of the thorax compared with the horizontal dimension during the period of rapid physical development is considered to affect intrathoracic pressure at the apex of lung, which would have some influence on enhancing cyst formation.

Abstract
A lowered subjective evaluation of the taste and flavor of beer due to staleness or to the addition of an unpleasant taste and flavor was found to be closely correlated with the urination rate. Beer in the same lot was compared immediately after shipment from the brewery and after leaving at room temperature for 1 month or 5 months. Each beer sample was given to volunteers at the rate of 3 ml/kg/15 min for 2 hours, and the urine volume was measured every 30 minutes. The urination rate was highest from the volunteers who drank fresh beer and lowest from those who drank 5-month-old beer. The subjective evaluation of both the taste and drinkability of 5-month-old beer was significantly lower than that of fresh beer. Beer samples with various unpleasant taste and flavor substances added lowered the urination rate. The results suggest that the perception of an unpleasant taste and off-flavor would lower the urination rate.

Abstract
Transforming growth factor-beta1 (TGF-beta1) is known as the growth factor that stimulates the synthesis of extracellular matrix. Recently, TGF-beta has been found to control the growth of cancer cells. Small chondroitin-dermatan sulfate (decorin) is an abundant extracellular matrix component. TGF-beta1 stimulates the synthesis of decorin, and decorin is considered to bind TGF-beta1. The activity of decorin in neutralizing TGF-beta1 activity suggests that decorin serves as a negative-feedback regulator of TGF-beta1 activity. To investigate the role and relationship of TGF-beta1 and decorin in the formation of central fibrosis in pulmonary adenocarcinoma, we performed an immunohistochemical study of TGF-beta1 and decorin in 61 cases of T1 pulmonary adenocarcinoma. Positive stainings for TGF-beta1 were shown in 40 cases and negative in 21 cases. Twenty-seven of 32 cases with central fibrosis were positive for TGF-beta1. Positive staining for TGF-beta1 was significantly related to the appearance of central fibrosis in pulmonary adenocarcinoma. When central fibrosis was composed of proliferative connective tissue with loose staining for decorin, cancer cells showed intense staining for TGF-beta1. When central fibrosis was composed of old fibrotic tissue with dense staining for decorin, cancer cells showed weak staining for TGF-beta1. Our results suggest that TGF-beta1 has an important role in the formation of central fibrosis in pulmonary adenocarcinoma, and decorin may play a role as a negative feedback regulator in the production of TGF-beta1 in pulmonary adenocarcinoma.

Abstract
A 68-year-old man suffering from chronic heart failure due to coronary artery disease (CAD) underwent rest technetium-99m (99mTc)-tetrofosmin and thallium-201 (201Tl) with reinjection studies, but died thereafter. The heart was removed and sectioned into short-axis slices and examined by gross and microscopic pathologic methods. A close correlation between the amount of residual cardiomyocytes and the level of regional tracer activity in the left ventricular wall was obtained for redistribution 201Tl, reinjection 201Tl and rest 99mTc tetrofosmin images. The correlation coefficients were r=0.901 for the 201Tl redistribution images, r=0.913 for the 201Tl reinjection images and r=0.917 for the rest 99mTc-tetrofosmin images. This case report provides further evidence of the validity of SPECT tetrofosmin imaging for the determination of myocardial viability in CAD.
