Abstract
A two-year-old male chihuahua suffered attacks of muscle weakness and immobility, although it had no family history of paroxysmal attacks. No neurological or blood biochemical abnormalities were recorded when it was first examined. The attacks were typically elicited by stimulation, such as feeding, and a case of sporadic narcolepsy-cataplexy was therefore suspected. Treatment orally three times a day with 1 mg/kg imipramine, was effective in reducing the attacks. The concentration of hypocretin-1/orexin A in the dog's cerebrospinal fluid was less than 80 pg/ml (22.5 pmol/litre), compared with normal canine levels of 250 to 350 pg/ml (70.0 to 98.3 pmol/litre), supporting a diagnosis of hypocretin-deficient narcolepsy.

Abstract
We report on two prepubertal narcoleptic boys with undetectable levels of hypocretin-1 (orexin-A) in their cerebrospinal fluid (CSF). The disease onset times were 6 and 8 years, and CSF was collected 8 and 20 months after the onset, respectively. The initial symptoms were excessive daytime sleepiness, cataplexy and disrupted nocturnal sleep. Both subjects are DRB1*1501 and DQB1*0602 positive. The measurement of CSF hypocretin-1 is valuable for the decisive diagnosis of narcolepsy and for selecting the type of treatment in prepubertal children. Our results suggest that a significant degree of hypocretin deficiency is already present at the disease onset.

Abstract
A 5-year-old girl suffering from hypersomnia due to acute disseminated encephalomyelitis (ADEM) is reported. Brain CT revealed a large low-density lesion involving the lentiform nucleus, posterior limb of the internal capsule, thalamus, posterior hypothalamus and midbrain in the left side. She was treated with intravenous dexamethazone. After the initial dose of dexamethazone, hypersomnia was dramatically and rapidly improved. A later brain CT study disclosed that the lesion in the brain disappeared. The brain lesion in this case involved the waking center in the brain, which was described by Von Economo. We concluded that hypersomnia in this case was due to ADEM involving the neural mechanism for maintaing wakefulness, probably in the thalamus and posterior hypothalamus. Repeat all night polysomnograpy in this case disclosed prolonged total sleep time and increased amount of stage 3-4 sleep in the hypersomniac state.

Abstract
We investigated the influence of melatonin on the human autonomic functions by measuring muscle sympathetic nerve activity (MSNA). Five healthy male volunteers took 3 mg of melatonin, and their plasma melatonin concentration, blood pressure, heart rate, and burst rate of MSNA were then recorded. The peak level of melatonin concentration showed a marked interindividual variation. Blood pressure was reduced significantly, while heart rate and burst rate of MSNA did not change significantly. These results indicate that melatonin has a hypotensive effect on blood pressure, and the central cardiovascular regulatory mechanism such as lowering of the baroreflex setpoint would be involved in the effect.

Abstract
Using a canine model of narcolepsy and selective DA and NE uptake inhibitors, we have recently shown that DA uptake inhibition promotes wakefulness, while NE uptake inhibition inhibits rapid eye movement sleep and cataplexy. In order to further delineate the respective roles of the dopaminergic and noradrenergic systems in the pharmacological control of symptoms of narcolepsy, we compared the potency of amphetamine isomers (D- and L-amphetamines) and a derivative (L-methamphetamine) on wakefulness and cataplexy. Their respective effects on these narcolepsy symptoms were then compared with their in vivo effects on extracellular DA levels in the caudate and NE levels in the frontal cortex during local drug perfusion in narcoleptic dogs. Polygraphic recordings demonstrated that D-amphetamine was about twice as potent as L-amphetamine, and was six times more potent than L-methamphetamine in increasing wakefulness and reducing slow-wave sleep. D-Amphetamine and L-amphetamine were equipotent in reducing rapid eye movement sleep and cataplexy, and L-methamphetamine was about half as potent as L- and D-amphetamines. D-Amphetamine was found to be more potent in increasing DA efflux than L-amphetamine, and L-methamphetamine was found to have little effect on DA efflux; there was no significant difference in the potencies of the three derivatives on NE efflux. The potencies of these amphetamines on wakefulness correlated well with DA, but not NE, efflux in the brain of narcoleptic dogs during local drug perfusion. Our current results further exemplify the importance of the DA system for the pharmacological control of electroencephalogram arousal and suggest that increased DA transmission mediates the wake-promoting effects of amphetamine-like stimulants.

Abstract
Polysomnography was used to assess the effect of thalidomide on human sleep. This compound significantly increased the time spent in REM and stage 3-4 sleep as compared with placebo. On the other hand, thalidomide significantly decreased the time spent in stage 1, while the time spent in stage 2 was unchanged. The effect of thalidomide on REM and stage 3-4 sleep is unique as compared with other hypnotics. Although the mode of action of this compound is unknown, further studies on thalidomide should help in our understanding of the mechanisms of sleep regulation.

Abstract
A case of adult onset myopathy who showed a peculiar sleep-related respiratory disorder (SRRD) is reported. She recovered from respiratory failure after tracheostomy and/or with the aid of the respirator used only during the night. Sleep study without the use of respirator revealed that her sleep was highly fragmented by frequent arousal responses due to inspiratory effort but not by apnea or hypopnea. To our knowledge this type of SRRD has not been described.

Abstract
We report two cases of self-induced water intoxication with rhabdomyolysis. They had been diagnosed as chronic schizophrenia, and admitted to mental hospitals. The patients were transferred to our emergency room because of sudden loss of consciousness and generalized convulsions. Laboratory findings revealed marked hyponatremia (case 1; 109 mEq/L and case 2; 104 mEq/L). CT scans showed the effacement of interhemispheric and bilateral sylvian fissures and sulci of the cerebral hemisphere due to diffuse brain edema. 10% glycerol and saline were intravenously injected to the patients. They recovered from hyponatremia after excreting a large amount of urine. Their disturbed consciousness recovered to the normal level in parallel with the normalization of their serum sodium concentration. Soon after the normalization of their consciousness level, their serum creatine kinase (CK) was markedly elevated (case 1; 13086 IU/L and case 2; 41832 IU/L), and their serum myoglobin level was also significantly elevated (case 1; 2670 ng/ml and case 2; 1420 ng/ml). A sufficient amount of transfusion was performed for avoiding the acute renal failure. The two patients recovered from rhabdomyolysis without any severe complication. We conclude that brain CT is useful for the diagnosis of brain edema, and monitoring of CK is also important to anticipate renal damage secondary to rhabdomyolysis.

Abstract
The therapeutic potential of thyrotropin-releasing hormone (TRH) and TRH analogs in narcolepsy, a sleep disorder characterized by abnormal rapid eye movement (REM) sleep and daytime sleepiness, was examined using the canine model. The effects of TRH and the biologically stable TRH analogs CG3703, CG3509, and TA0910 on daytime sleep and cataplexy, a symptom of abnormal REM sleep, were assessed using polysomnographic recordings and the food elicited cataplexy test (FECT), respectively. CG3703 (100 and 400 microg/kg, i.v.) and TA0910 (100 and 400 microg/kg, i.v.) significantly increased wakefulness and decreased sleep in narcoleptic canines, whereas TRH (400 and 1600 microg/kg, i.v.) had no significant effect. TRH (25-1600 microg/kg, i.v.) and all three TRH analogs, CG3703 (6. 25-400 microg/kg, i.v., and 0.25-16 mg/kg, p.o.), CG3509 (25-1600 microg/kg, i.v.), and TA0910 (25-1600 microg/kg, i.v.), significantly reduced cataplexy in canine narcolepsy. These compounds did not produce any significant side effects during behavioral assays, nor did they alter free T3 and T4 levels in serum even when used at doses that completely suppressed cataplexy. Although more work is needed to establish the mode of action of TRH analogs on alertness and REM sleep-related symptoms, our results suggest a possible therapeutic application for TRH analogs in human sleep disorders.

Abstract
BACKGROUND We performed a multivariate analysis of clinical variables in 320 patients with renal cell carcinoma to identify important prognostic factors for long-term survival. METHODS We retrospectively reviewed the medical records of 320 patients who presented with renal cell carcinoma. Survival curves were calculated by the Kaplan-Meier method and statistical differences were determined by the log-rank test. Significant prognostic factors were evaluated by Cox's multivariate proportional hazard model. RESULTS The median follow-up period was 29 months. The overall survival rates at 1, 5, and 10 years were 90.0%, 77.6%, and 69.9%, respectively. Seventeen of the 19 prognostic factors evaluated were shown to be significant by the log-rank test: patient age, sex, performance status, body temperature, erythrocyte sedimentation rate (ESR), levels of hemoglobin, alpha 2-globulin, C-reactive protein, fibrinogen, immunosuppressive acidic protein (IAP), size or involvement of tumor (T classification), regional lymph node involvement (N classification), extent of metastasis (M classification), pathologic grade, tumor cell type, mode of tumor infiltration, and the modality of treatment (curative surgery). Among them, the body temperature, ESR, alpha 2-globulin, fibrinogen, IAP, and mode of tumor infiltration were excluded from multivariate analysis because of missing data. Curative surgery was also excluded because it is a treatment modality and different from the other variables which are clinical or pathologic characteristics. From the remaining 10 variables, multivariate analysis showed that age (P = 0.0389), N classification (P = 0.0289), and M classification (P < 0.0001) were important and independent prognostic factors for long survival. CONCLUSION This analysis showed that age, N classification, and M classification were the most important factors predicting long-term survival of patients with renal cell carcinoma.

Abstract
BACKGROUND The clinical significance of pretreatment serum prostate-specific antigen (PSA) values was studied to determine the ability to predict clinical stage and prognosis using a relatively large number of patients with prostate cancer. METHODS Serum PSA values at diagnosis were analyzed from 749 patients with newly-diagnosed prostate cancer and registered in the Tokai Urological Cancer Registry. Correlations between the PSA value, the clinical stage and prognosis of the patients were evaluated. RESULTS Serum PSA values at each stage of diagnosis showed positivity (> or = 3.6 ng/mL) in 23% (stage A1) to 91.2% (stage D2) of patients, and it was possible to obtain statistical differences between the stages, even between A1 and A2. Based on a cumulative study of PSA distribution, stages greater than A2 could be diagnosed using a cut-off of 7.2 ng/mL, with a 99.2% positive predictive value (PPV), and a 16.2% negative predictive value (NPV). At a PSA level of 10.8 ng/mL, stages greater than B2 could be predicted with a PPV of 95.3% but an NPV of 40.3%. Pretreatment PSA values were a significant prognostic indicator in stage D2 patients using 100 to 150 ng/mL as the cut-off values. These differences were primarily found in the poorly differentiated group, which showed a statistical difference using cut-off PSA values from 75 to 150 ng/mL. CONCLUSIONS Serum PSA levels from a large number of patients can be used to predict the stage and prognosis of prostate cancer patients.

Abstract
Thalidomide is a sedative hypnotic that was widely used in the 1950s but was withdrawn due to its teratogenic properties. The compound has recently been reintroduced as an immune modulating agent. Thalidomide significantly aggravates canine cataplexy, a pathological manifestation of rapid eye movement (RFM) sleep atonia seen in narcolepsy. This compound also increases REM sleep and slow wave sleep in these animals. In vitro receptor binding and enzyme assays demonstrate that thalidomide does not bind to or enzymatically modulate the neurotransmitter systems reported to be involved in the regulation of cataplexy. Thalidomide may therefore affect cataplexy through its immune modulation properties. Further studies on the mechanisms of action of thalidomide should increase our understanding of the pathophysiology of this disabling disorder.

Abstract
A 50-year-old Japanese female with a long history of Raynaud's phenomenon presented with progressive dyspnea due to pulmonary hypertension. The diagnosis of systemic lupus erythematosus was confirmed by proteinuria, lymphocytopenia, bilateral pleurisy, and a seizure of convulsion which was consistent with neurological manifestations of systemic lupus erythematosus, whereas the antinuclear antibody showed a low titer. Despite improvement in the activity of systemic lupus erythematosus, steroid treatment did not alter the progression of pulmonary hypertension, which increased in severity, eventually resulting in her death. We believe pulmonary hypertension to be an unusual but critical complication of systemic lupus erythematosus.

Abstract
Muscle sympathetic nerve activity (MSNA) was recorded from peroneal nerve in 4 OSAS patients during sleep. During apneic episode, MSNA was enhanced, but it did not increase progressively toward the end of the apneic episode. MSNA remained at a stable level in the later part of an apneic episode. A surge of MSNA took place just preceding or just at the end of an apneic episode and it was followed by a transient marked blood pressure elevation.

Abstract
The distribution of the arterial supply and innervation of skeletal muscle in the whole human body has been being researched in our laboratory. The results obtained on the biceps brachii from 25 bodies (50 sides) are reported here. Generally, in this muscle, A. coracobrachialis (Cb, SATO, 1980), a branch of A. axillaris (Ax), is distributed at the upper muscle bundles of the short head after running parallel to N. musculocutaneus (Nmc) and supplying M. coracobrachialis. The main artery (Ma), which is a branch of A. brachialis (Br), is distributed at the upper and middle parts of both heads, and the point where Ma enters the muscle bundles almost coincides with the point where R. brachialis (Rb) branches from Nmc. R. biceps brachii (Rbi), which is distributed only at this muscle and Om, the common trunk to other muscles, is distributed at the lower part of the muscle bundles. The arterial supply of this muscle was classified as follows according to the conditions of origin and its distribution. Type I: Ax(Cb) was distributed to the upper part of the muscle bundle. Type II: The absence of Ax(Cb) in the upper part of the muscle bundle. Type A, a and 1: Ma.Br(Om) supplying the long, short and both heads of the biceps brachii. Type B, b and 2: Ma.Br(Rbi) supplying the long, short and both heads of the biceps brachii. In the long head, Type II-A accounted for 62.0%, Type II-B for 30.0%. In the short head, Type I-a was 62.0%, Type I-b 28.0%. In both heads, Type I-1 was 62.0%, Type I-2 28.0%. There were significant differences in the distribution of the nutrient arteries between the long and short heads. A. brachialis superficialis (Bs) was recognized in 3 of these cases (2 cases of Type III and 1 case of Type VII by Adachi's classifications), which were rare cases. In these cases, arterial branches other than Cb branching from A. brachialis profunda are branches of Bs. This means, judging from ontogeny, that Bs, the blood vessels in the superficial layer, supplies this muscle, which belongs to the superficial layer of the brachium.

Abstract
Ganglioneuroblastoma is an extremely rare neoplasm of adults. We present a case of adrenal ganglioneuroblastoma in a 47-year-old female with disseminated bone marrow involvement. Bone marrow involvement was the major manifestation which determined the mortality of this patient. This case suggests that the diagnosis of bone marrow involvement should be carefully considered even in adult-onset ganglioneuroblastoma.

Abstract
We examined 94 axillary regions of 47 Japanese adults and found the muscular arch of the axilla (Maa) in five sides of three cadavers as well as the tendinous arch of the axilla (Taa) in two sides of two cadavers. The results are summarized as follows: 1) The frequency of Maa was 6.4% of the total bodies and 5.3% of the sides in this series. 2) In the left side of a 57-year-old male (No. 427), Maa was attached to the surface of the coracobrachialis muscle after fusing with the dorsal surface of the inserting tendon of the pectoralis quartus muscle. Both muscles were supplied by the caudal pectoral nerve (Npc) from the medial pectoral nerve. Moreover, in this same specimen, the sternalis muscle was recognized on the ventral surface of the pectoralis major muscle. In the left side of a 93-year-old female (No. 386), the cranial part of the muscular arch of the axilla (Cpa) was extended to the coracoid process by a tendon and attached to the abdominal part of the pectoralis major by two muscle bundles supplied by independent branches from Npc. One muscle bundle was attached to the lower margin of the abdominal part of the pectoralis major on the same plane, and the other bundle was located on the dorsal surface of the abdominal part. In a 74-year-old female (No. 411), the well-developed lateral part of the muscular arch of the axilla (Lpa) was attached to the inferior side of the tendinous arch. According to Ruge (1914) and Kasai et al. (1977), this arch was in the transition of the muscle bundle of Cpa to the arch. In the right side of the same specimen, only the thoracodorsal nerve (Ntd) was distributed into Lpa, whereas in the left side, only Npc supplied branches to Lpa. 3) The axillary arch was classified into 8 types based on the form and the supplying nerve of Cpa and Lpa. Cpa consisting of the muscle bundle is Type I, and Cpa consisting of the tendinous arch is Type II. We proposed that only Type II-A, with Cpa as tendinous arch and no Lpa, be designated as Taa (found in two cases), and the others as Maa. The following types were found in this study: Type I-A, consisting of only Cpa supplied by Npc (two cases); Type I-D, consisting of Cpa supplied by Npc and Lpa supplied by Ntd (one case); Type II-B, consisting of the tendinous arch and Lpa supplied by Npc (one case); Type II-D, consisting of the tendinous arch and Lpa supplied by Ntd (one case). 4) From the above findings, it can be suggested that Maa of varying shapes have been formed by a portion of the latissimus dorsi muscle supplied by Ntd, together with the pectoralis subcutaneous muscle, consisting of the pectoralis abdominalis, humeroabdominalis, humerodorsalis and ventrolateralis muscles supplied by Npc. The latter three muscles were proposed by Ura (1937) as the panniculus carnosus muscle, which was well developed in some lower mammalian orders. However, early investigators suggested that Maa was derived from the panniculus. Maa might have occurred as a rudimentary phylogenetic remainder in an early human embryonic stage.

Abstract
A 34-year-old male was admitted to our hospital because of anorexia and nausea in September, 1987. On admission, anemia, thrombocytopenia and hypercalcemia were observed, and the peripheral blood showed leukocytosis with atypical plasma cells (50%). Bone marrow aspiration showed hypercellularity, with a presence of atypical plasma cells (82%). The M-type protein in the serum and urine was identified as lambda Bence Jones protein by immunoelectrophoresis. On systemic skeletal X-rays, osteolytic lesions were not detected. Thus, a diagnosis of plasma cell leukemia associated with hypercalcemia was made. Hypercalcemia was treated successfully with overhydration. However the disease was refractory to combination chemotherapy, and at 10 months after diagnosis, he died of septic candidiasis. Hypercalcemia associated with plasma cell leukemia in its initial stage is rare.

Abstract
The amount of polyamines in urine from patients with various neoplasms is larger than in normal subjects. We have determined the concentration of 5'-methylthioadenosine (MTA), a by-product of the polyamine biosynthesis, in patients with malignancies as well as normal subjects. Our studies indicate that the amount of MTA in urine from patients with leukemias and malignant lymphomas was higher than in normal subjects (p less than 0.005). Urine samples from patients with other malignancies contained normal amounts of MTA. The levels of blood MTA in patients with leukemias before treatment or in relapse was higher than in control subjects (p less than 0.005), while in patients with other malignancies and leukemia in remission, the levels were not different from control subjects. Peripheral blood MTA levels clearly decreased after effective chemotherapy. The measurement of MTA levels in urine and blood may not be as useful as polyamine assays for the detection of malignancies, but blood levels of MTA may be useful as an indicator of the efficacy of chemotherapy in leukemic patients.

Abstract
During about 10 years from November, 1977 to March, 1987, two hundreds and fifty-five patients with bladder tumors were treated at the Department of Urology, Hamamatsu University School of Medicine and the affiliated hospitals. There were 198 males and 57 females with the highest age incidence in the seventies. Histologically, 242, 11 and 2 tumors were of transitional cell, squamous cell and adenocarcinoma, respectively. Of the 242 transitional cell carcinomas, 7 were Tis; 43 Ta, 111 T1, 33 T2, 19 T3, 5 T4, 14 M+ (with metastatic lesion), and 10 TX. As to grading, 6 was G0; 66 G1, 100 G2, 64 G3, and 6 GX. Staging was correlated with grading. The 5-year survival rates (Kaplan-Meier's method) were 64% in patients with transitional cell carcinoma; 58% in those with squamous cell carcinoma. In patients with transitional cell carcinoma, the 5-year survival rates were 100% for G0, 73% for G1, 73% for G2 and 40% for G3. As to staging, the 5-year survival rates were 67%, 81%, 81%, 35%, 41%, 40% and 12% in patients with stage of Tis, Ta, T1, T2, T3, T4 and M+, respectively. As to the initial treatment, the 5-year survival rates after TUR (137 cases), partial cystectomy (4 cases) and total cystectomy (56 cases) were 81%, 36% and 61%, respectively. The rate of intravesical recurrence after TUR was evaluated with the cumulative non-recurrence rate calculated by Kaplan-Meier's method.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
During about 10 years from November, 1977 to March, 1987, 46 patients with renal pelvic and ureteral tumors were treated at the Department of Urology, Hamamatsu University School of Medicine and the affiliated hospitals. There were 34 males and 12 females with the highest age incidence in the seventies. Histologically, 44 transitional cell carcinomas and 2 squamous cell carcinomas were found. Of the 44 transitional cell carcinomas, 1 was Tis; 13 T1, 2 T2, 8 T3, 15 M+ (with metastatic lesion), and 5 TX. As to grading, 1 was G1; 24 G2, 15 G3, and 4 GX. Staging was correlated with grading. The 5-year survival rates (Kaplan-Meier's method) were 37% in patients with transitional cell carcinoma. Among patients with transitional cell carcinoma, the 5-year survival rate was 43% for G2 and 42% for G3. As to staging, the 5-year survival rates were 71% and 46% in patients with stage of T1 and T3, respectively. No patient with M+ survived longer than 4 years. The 5-year survival rates were 38% and 34% in renal pelvic tumors (24 cases) and ureteral tumors (20 cases), respectively. As to the treatments, the 5-year survival rates after curable treatment (24 cases) and non-curable treatment (20 cases) were 63% and 7%, respectively.
