Abstract
Two elderly patients with sarcoidosis complicated with Sjögren's syndrome are described. Case 1: A 70-year-old woman was admitted due to dry eyes. Histological examination of a minor salivary gland specimen revealed lymphocytic infiltration, which was compatible with Sjögren's syndrome. Because uveitis was demonstrated, transbronchial lung biopsy (TBLB) was performed, to confirm a diagnosis of lung sarcoidosis. Histological examination of TBLB showed non-caseating granulomas compatible with sarcoidosis. Case 2: A 70-year-old woman was admitted due to dyspnea on exercise and blurred vision. Two years previously, Sjögren's syndrome was diagnosed because of a positive Shirmer test and positive SS-A antibody. Result of ophthalmic examination were compatible with uveitis. Histological examination of TBLB showed non-caseating granulomas compatible with sarcoidosis. Certain similarities between sarcoidosis and Sjögren's syndrome in terms of immunological aspects have attracted attention. In the present manuscript, a possible relationship between the two diseases as well as the characteristics of elderly sarcoidosis are discussed.

Abstract
Mouse astroglial cells, which were cultured on an electrode, were found responsive to an electric stimulation of sine wave potential in enhancing hsp70 mRNA resulting from an activation of hsp70 gene expression. On the basis of this finding, electrically responsive cells were established by transfecting mouse 3T3-L1 cells with a constructed plasmid encoding hsp70 promoter and the firefly luciferase gene. A stable cell line has been established through selection of heat-stimulated luciferase expression. A 1-h electric stimulation of the cells resulted in activation of luciferase expression, which was confirmed to produce an increase in light emission. The sequential pattern of the electrically stimulated expression of luciferase was found different from that of the heat stimulation. Furthermore, the promoter was activated depending on the potential and duration of the stimulation applied. Consequently, the electric stimulation has proven effective on activating hspP70 promoter. This cell line is feasible in expressing the gene of interest by electrical stimulation, which lead us to construct environment responsive cells in general.

Abstract
Sweet's syndrome occurring during the course of interstitial pneumonitis in a 70-year-old woman was encountered. She was admitted because of dyspnea on exercise, dry cough and interstitial shadow on chest x-ray. Lung biopsy, together with other findings confirmed interstitial pneumonitis. Five days after admission, genital ulcer and aphtha on the oral mucosa were detected and exudative erythema appeared on her right shoulder, chest and back. Histological examination of the skin lesions demonstrated numerous nutrophilic infiltration in the upper dermis, indicating Sweet's syndrome. The skin eruption rapidly disappeared on treatment with colchicine. Although six months after admission interstitial pneumonitis caused respiratory failure, treatment with prednisolone and cyclophosphamide was effective. Serological and immunological tests demonstrated hyper-gammaglobulinemia and positive reaction for anti SS-A antibody. Pathological examination of the lip revealed numerous lymphocyte infiltrates around the duct of the minor salivary gland, suggesting Sjögren's syndrome as the background disease of Sweet's syndrome and interstitial pneumonitis. This evidence indicating that even in elderly patients, skin lesions of Sweet's syndrome may reveal the background disease.

Abstract
Chronic obstructive pulmonary disease (COPD) is more important as a cause of morbidity than as a cause of mortality but estimates of its frequency and distribution are inadequate and incomplete. According to annual report of World Health Organization, in 1998 there were estimated to be 52.2 millions deaths in the world, among them 2.9 millions were due to respiratory diseases and almost of them were COPD. Estimates of prevalence COPD vary depending on the diagnostic criteria used, the age and sex composition of the population, their exposure to cigarette smoke and possibly to other harmful environmental influences. In the present review, we discuss the problems arising in the data of morbidity and mortality of COPD in Japan.

Abstract
We tested the hypothesis that serum IgE concentrations may be influenced by the severity of respiratory symptoms, impairment of pulmonary functions, and smoking history in elderly patients with bronchial asthma and/or chronic obstructive pulmonary disease (COPD). A total of 325 elderly outpatients aged over 65 years were enrolled in the study: 112 (22 men, 90 women) with bronchial asthma (BA), 135 (118 men, 17 women) with COPD, and 78 (56 men, 22 women) with both COPD and asthma (COPD/BA). The mean ages for the 3 groups were 74.3,76.0 and 76.6 years, respectively; the age differential was not significant. As a group, the male subjects displayed higher serum IgE concentrations than the female subjects. Also, ex-smokers and current smokers showed higher serum IgE concentrations than patients who had never smoked, and patients in the BA group had higher serum IgE concentrations than those in the COPD or COPD/BA groups. Although serum IgE concentrations were increased in BA patients with decreased FEV1.0 levels, the reverse was observed in the COPD patients. Peripheral blood eosinophil counts for men and women were higher in the BA group than in the COPD group. A positive correlation between serum IgE concentration and eosinophil count was observed in the BA group. Although bronchial asthma and COPD in the elderly have been considered to be pathologically similar, the findings of our study suggested they are probably different in terms of serum IgE concentration, pulmonary function, and smoking history.

Abstract
To elucidate the involvement of NO in pain transmission in humans, we measured NO metabolites (nitrite/nitrate) in the CSF of patients with painful diseases using an NO analyzer based on the Griess method. The nitrite/nitrate levels in patients with degenerative lumbar disease (DLD), but not those with fracture or appendicitis, were significantly higher than those in an age-matched control group. The duration of pain in the DLD group was much longer than that in the fracture or appendicitis group. The nitrite/nitrate levels in the middle-aged and elderly DLD patients depended on the duration of pain. These data probably suggest that the duration of pain is critical for the elevation in nitrite/nitrate levels.

Abstract
A 62-year-old Japanese male developed acute bacterial meningitis. Administration of ABPC, CDZM, INH, and RFP was started. The causative bacteria was identified as penicillin-resistant Streptococcus pneumoniae (PRSP) 3 days later. We changed ABPC to PAPM/BP and the bacterial meningitis improved dramatically. Measurement of minimum inhibitory concentration (MIC) of the bacterial strain from CSF and blood showed that it is susceptible to PAPM/BP and RFP. Mechanism of drug resistance is considered to be gene mutations of penicillin binding protein (PBP) that decreases drug affinity to PBP. Recently penicillin resistance of Streptococcus pneumoniae has been found to be associated with mutations of pbp-2b, 1a genes and the cefem resistance of that is with those of pbp-2x, and 1a genes. By PCR (polymerase chain reaction) analysis we identified the mutations of pbp-1a, 2x, and 2b genes of the isolated strain of Streptococcus pneumoniae. We emphasize the importance of detection of pbp gene mutations for the diagnosis of PRSP infections.

Abstract
A patient in a blastic phase of chronic myelocytic leukemia developed multiple arterial emboli that originated from mitral valve vegetation. The diagnosis of infective endocarditis was not confirmed because blood cultures, serological assays and other examinations detected no pathogens. He died of intracranial hemorrhage after thrombolytic manipulation for embolization of the abdominal aorta and an autopsy was performed. Polymerase chain reaction analysis and Southern blot analysis of tissues from the mitral valve revealed Aspergillus species as the cause of the endocarditis, although none of the tissue specimens were culture-positive. These molecular analyses will be useful in the diagnosis of various types of Aspergillus infections.

Abstract
A case of an adrenal incidentaloma in a 57-year-old man with silent 21-hydroxylase deficiency is reported. Abdominal computed tomography revealed a right adrenal tumour of 6cm in diameter. There was no evidence of adrenal hormone excess. However, after surgical removal of the adrenal tumour, the patient developed acute adrenal insufficiency. Adrenocortical function has remained low ever since surgery. Pathological examination of the tumour revealed a cortical adenoma. On the basis of increased plasma renin activity and serum 17 alpha-hydroxyprogesterone concentration and decreased 21-hydroxylase activity of the adenoma tissue, the patient was diagnosed as having systemic 21-hydroxylase deficiency. There are two possible mechanisms for the persistent adrenal insufficiency; first the residual left adrenal gland may have been originally hypo-functioning for some reason and, second, the left gland may have lost the ability to regenerate following prolonged suppression by the adenoma. In cases of adrenal incidentalomas with 21-hydroxylase deficiency, the indications for surgical removal should be carefully considered.

Abstract
Acute autonomic and sensory neuropathy (AASN), one subtype of acute pandysautonomia, in which dorsal root ganglia and autonomic ganglia are involved is uncommon. Little is so far known on central nervous system involvement in AASN. In the present paper we described a rare case of AASN associated with the central nervous system manifestations such as galactorrhea-amenorrhea syndrome and intractable anorexia. A 30-year-old woman rapidly developed burning pain and numbness in her arms and legs as well as orthostatic syncope. She had severe anorexia and no no menstruation from onset. On physical examination, she was emaciated. There was marked orthostatic hypotension with tachycardia. Skin was dry. Moderate galactorrhea was detected. Neurological examination showed prominent paresthesia and dullness of superficial sensation, predominantly to pinprick and thermal stimuli, segmentally over the neck, occipital scalp, and extremities. Deep sensation was intact. She had no weakness or ataxia. Deep tendon reflexes were almost normal. NCV and SEP were normal, while EEG was abnormal. Sural nerve biopsy demonstrated axonal degeneration with the loss of myelinated, predominantly in small-caliber fibers, and unmyelinated fibers. The levels of HVA and MHPG in CSF were decreased. The autonomic nervous function tests revealed postganglionic dysfunction. alpha-adrenergic system was predominantly impaired, while beta-adrenergic system was relatively preserved. The endocrinological studies demonstrated mild or moderate elevation of PRL basal value and hyper-response of PRL and LH for TRH and LH-RH loading test, which suggested disorder of the hypothalamo-hypophysial system. Cranial MRI showed moderate dilatation of the 3rd ventricle.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Only a few cases of carcinomatous neuropathy with tonic pupils have been reported. In the present paper we described a 53-year-old woman with subacute sensory neuropathy who had presented with bilateral tonic pupils. She noticed numbness over the medial aspect of the left thigh in March, 1988, and then developed dysesthesia over the left forearm and hand, mild weakness of left upper and lower extremities and urinary disturbance. Neurological symptoms were subacutely progressive and she was bed-ridden in May. She was admitted to our hospital in June, 1988. On examination, she had body-weight loss of 6 kg during the last six months and general status was otherwise unremarkable. She had anisocoria; the left pupil was larger in daylight than the right, while smaller in dim light. The left pupil scarcely reacted to light, but promptly constricted to near vision. The right pupil constricted normally to light and near vision. An instillation of 0.0625% pilocarpine solution showed supersensitive response of both pupils. An instillation of 1.25% epinephrine solution demonstrated mild dilation of both pupils. Thus, it was conceivable that she had postganglionic ciliary nerve damage characteristic of tonic pupil as well as the lesion of sympathetic nerve innervating pupillary dilator. She had severe sensory ataxia and pseudoathetosis of the hands. Weakness was mild to moderate in extremities. Almost all deep tendon reflexes were absent. All modalities of sensation, particularly on deep sense, were severely involved with sea-level-type distribution below Th7, and over C2 to C3 regions on the left side.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A retrospective study on the role of pancreatic B-cell insulin secretory capacity in the development of proliferative diabetic retinopathy was performed in 160 diabetic patients with a duration of diabetes of more than 10 years (mean 19.5 +/- 7.9 years). Pancreatic B-cell insulin secretory capacity was assessed in terms of the quantity of C-peptide excreted into urine per day (24-h urinary C-peptide). When the patients were divided into three groups according to the quantity of 24-h urinary C-peptide (group I, C-peptide less than 30 micrograms, n = 49; group II, 30 micrograms less than or equal to C-peptide less than 80 micrograms, n = 76; and group III, C-peptide greater than or equal to 80 micrograms, n = 35), the prevalence of proliferative diabetic retinopathy was much higher in group I (26.5%) than in group II (5.3%) or group III (2.9%). The incidence of proliferative diabetic retinopathy during the follow-up period (mean 9.8 +/- 4.8 years) was also highest in group I (20.0%, 2.7%, and 2.9% in groups I, II, and III, respectively). Other factors which might affect the development of proliferative diabetic retinopathy, including duration of diabetes and past glycemic control, were comparable in these three groups. In contrast, a division of the patients according to glycemic control revealed a strong correlation between glycemic control and background diabetic retinopathy whereas no such correlation was apparent with proliferative diabetic retinopathy. These data are consistent with the view that low pancreatic B-cell insulin secretory capacity may be a risk factor for the development of proliferative diabetic retinopathy.

Abstract
We report a malformed girl with a single chromosome band deletion of 4q26 in peripheral lymphocytes. This patient is the fourth case reported with an interstitial deletion involving 4q26 and has the smallest deletion of those reported. Deletion mapping indicates that psychomotor retardation, coloboma, prominent forehead, epicanthus, broad based nose, and broad, thin upper lip are associated with monosomy 4q26, and that gene(s) associated with Rieger syndrome can be excluded from the 4q26 segment.

Abstract
It has been unclear until now as to whether human astrocytes proliferate through mitosis or through amitosis, and little attention has been paid to the biological meaning of glial cell division. We examined an autopsy case of a 53-year-old man who died of brain abscesses and have found GFAP-positive mitotic cells in the zone between the abscess cavity and the reactive gliosis. The results suggest that human normal astrocytes which act in response to the brain abscess proliferate the process of mitosis, and become reactive to repair the lesions.

Abstract
An 8-year-old girl with chronic idiopathic intestinal pseudo-obstruction (CIIP), who is the first case of CIIP in Japan, has been receiving total parenteral nutrition (TPN) for more than 6 years. During this time, she experienced deficiencies of copper, zinc, vitamin A, vitamin B12, folic acid, and biotin, and an excess of vitamin A; she exhibited a series of signs and symptoms due to these deficiencies and vitamin A overdosage. Nevertheless, careful monitoring of serum levels of trace elements and vitamins and appropriate therapy have almost solved these problems. She has achieved normal physical and mental development and goes to school, while receiving home parenteral nutrition with an ambulatory infusion system.

Abstract
A significant decrease in the proportion of 13q14-deleted cells over a 9-month period was observed in a boy with retinoblastoma and 13q14 deletion mosaicism. To evaluate whether this phenomenon is generally the case, the bloods of three retinoblastoma patients with 13q14 deletion mosaicism reported in 1981 and 1982 were reexamined. A significant decrease in the proportion of abnormal cells was observed in three of four patients including the present case, suggesting that a 13q14 deletion mosaicism might disappear with age in some individuals.

Abstract
In our study, we found a recognizable pattern of the midface in three retinoblastoma patients with interstitial deletion of chromosome 13 in lymphocytes. Further photographs of patients reported by other authors confirmed our conclusion that the midface in children with interstitial deletion of 13q from q12 to q22, always involving q14, is characterized by prominent eyebrows, broad nasal bridge, bulbous tip of the nose, a large mouth with a thin upper lip, and a long philtrum. This midface pattern could not be recognized in patients with normal karyotypes, suggesting that the critical segment for the midface phenotype as well as for retinoblastoma may exist in band 13q14.

Abstract
In serial cytogenetic examinations of peripheral lymphocytes from retinoblastoma patients, we found a patient with sporadic bilateral retinoblastoma with a de novo mutation of a 13/18 translocation, with their respective breakpoints at 13q141 and 18q122. The simultaneous de novo occurrence of retinoblastoma and the chromosomal rearrangement involving 13q14 in the proband suggests that the gene locus for retinoblastoma is at 13q141, particularly at the distal portion of it. Deletion mapping data are compatible with this suggestion.

Abstract
The results of a lymphocyte chromosome survey of retinoblastoma (Rb) patients using a method able to detect a relatively low proportion mosaicism of 13q14 deletion are presented. Three out of 42 Rb patients had abnormal karyotypes; two mosaic cases with the karyotype 46,XY,del(13) (q14.1q14.3)/46,XY and 46,XX,del(13)(q14.1q14.3)/46,XX (the proportions of 13q14-cells, 51% and 9%, respectively), and the other with the karyotype 46,XY,del(13)(q14.1q21.2). All of these three cases had bilateral sporadic Rb. Two mosaic cases had an apparently normal phenotype except for Rb. These data suggest that the frequency of Rb cases with a 13q- cell line in lymphocytes may be greater than that which has been reported.

Abstract
Two male siblings with a short rib-polydactyly syndrome, Majewski type (Majewski syndrome), are reported. To our knowledge, the present report is the first one of siblings each confirmed to be affected by Majewski syndrome, and it may therefore contribute to establishing the mode of inheritance.

Abstract
The case of a 5-month-old male infant with 18p- mosaic, who has intractable seizures and severe ophthalmological abnormalities in addition to many clinical manifestations usually described in the 18p- syndrome, is reported. The proportions of abnormal cells are 7-8% in blood and 55% in skin. About 35% of the short arm of chromosome 18 is deleted. to our knowledge the present report is the fifth one of 18p-mosaic. The main interest of this case resides in the fact that it shows a serious clinical picture despite the low proportion of abnormal cells in blood and the small degree of deletion of the short arm of chromosome 18.

Abstract
Two children had prepubertal XY gonadal dysgenesis. A 7-year-old girl with clitoral enlargement had a left ovarian tumor that contained a dysgerminoma; the right gonad proved to be a gonadoblastoma. The second child (a 2-year-old girl) showed poor physical development and slight virilization of the genitalia. Her bilateral dysgenetic gonads were removed at exploratory laparotomy. The occurrence of gonadal tumors in XY gonadal dysgenesis is increased. It is probably related to the hypergonadotropinism existing from childhood as well as to genetic predisposition of the cryptorchid testis in the presence of a Y chromosome. Our first patient is one of the youngest who had XY gonadal dysgenesis iwth gonadoblastoma reported. The indication of prophylactic gonadectomy in XY gonadal dysgenesis is emphasized.
