Muscle tenderness or stiffness is generally attributed to local muscle spasm or aggravated tonus however electro-myographic studies have indicated no spontaneous discharge as usual and any kind of change of N M U weve patterns, certainly. There is a great deal of uncertainty about the fundamental chracter, identified factor of these conditions.
To analize (_??_-S curves) -the mean inteerval (_??_) of the single unit NMU discharges and the standard deviation (S) of the same it was learned that these phenomena could be classified into two types of muscle activities, the one is kinetic activity (K-curve) and the other is tonic one (T-curve) so to speak. We conducted examinations concerning about the character of the notor unit activity of the trigger point in low back pain patient with _??_-S relation. In comparison with the distribution of (_??_-S) of the low back pain patient group (14 patients, 295 units) and that of the control group most (_??_) was up to about 120 msec. with (S) relatively stable, an almost horizontal distribution along the x-axis with an increase when (_??_) was any larger.
As compared to this, in most examples in the lumbago group (_??_) was horizontally up to 120 msec. after which a gradual rise xas indicated. The various distributions showed that that of the lumbago group was moved to the right of the awis of co-ordination as was the recovery line. Consequently, we observed that the NMU discharges of the trigger point in low back pain patients showed more tonic activity than that of normal subjects. And this finding strongly indicates that voluntary muscular activity in trigger points is under the predominant influence of spinal motoneuron than homonymous neuron segmentally.

Cardiac surgery associated with idiopathic thrombocytopenic purpura (ITP) is rare, and only 10 cases have been reported in the literature. In this report, we described the successful surgical management of a patient with ITP, diabetes mellitus and malfunction of mitral bioprosthetic valve. A 62-year-old male, who underwent mitral valve replacement (MVR) by means of a Carpentier-Edwards valve prosthesis and CABG ten years ago, developed malfunction of mitral prosthetic valve. The preoperative platelet count was 52, 000/mm3 and PA-IgG elevated markedly. The diagnosis of ITP was based on findings of bone marrow examinations. Thrombocytopenia was treated by steroids for 4 weeks and large dose γ-globulin (20g/day) for 5 days preoperatively, but platelet count did not increase. Platelet rich plasma (PRP) was transfused prior to cardiopulmonary bypass (CPB) and fresh blood was added to the priming material of CPB. Re-MVR was performed by means of mechanical valve prosthesis. After operation, large doses of γ-globulin and transfusion of PRP were performed for 3 days, and the postoperative course was uneventful. Other reports in addition to this study reveal that cases of cardiac surgery associated with ITP should be initially controlled preoperatively with steroids or high-dose γ-globulin, and if these treatments are harmful or ineffective, splenectomy should be considered.

A 60-year-old man, who had undergone mitral valve repair with quadrangular resection of the posterior mitral leaflet and ring annuloplasty with a Cosgrove-Edwards ring, developed severe mechanical hemolytic anemia. Doppler echocardiography showed only mild residual mitral regurgitation, but turbulent jet was directed toward the annuloplasty ring. Because of unremitting hemolysis requiring multiple transfusions and the occurrence of renal dysfunction, he underwent replacement of the mitral valve with a St. Jude Medical valve. Inspection of the annuloplasty ring at operation showed no evidence of dehiscence, but the area of the annuloplasty ring adjacent to the posteromedial commissure showed no endothelization. After the reoperation, the hemolysis and general condition immediately improved. This experience made us realize the possibility that a high-velocity regurgitant jet toward the cloth-covered annuloplasty ring, even if it mild, can cause severe hemolysis.

Pancreatic neuroendocrine tumors, relatively rare cancers, mostly arise in the pancreatic parenchyma with infrequent involvement of the main pancreatic duct. Now and then, however, case reports have been published on pancreatic neuroendocrine carcinoma in which the main pancreatic duct is obstructed by tumor cells with severely fibrous stromal cells. Here, in this paper, we report a case of pancreatic neuroendocrine carcinoma with obstruction of the main pancreatic duct. A 59-year-old man complained of right upper abdominal pain. Magnetic resonance cholangiopancreatography and fat-suppressed T1-weighted magnetic resonance imaging showed gallbladder stones, a low-intensity-area measuring 8 mm in diameter in the pancreatic body, and club-shaped dilatation at the distal end of the pancreatic duct. The patient was thus diagnosed with a tumor in the pancreatic body and cholecystolithiasis, and underwent distal pancreatectomy and cholecystectomy. HE-staining showed tumor cells with eosinophilic cytoplasm and nuclear atypia. The infiltrative growth of the cells with severe fibrosis caused stenosis of the pancreatic duct. Based on the positive results of immunohistochemical staining for chromogranin A and synaptophysin and the Ki-67 index, the tumor was finally identified as pancreatic neuroendocrine carcinoma. The patient has been under follow-up with no additional treatment for >3 years since the surgery, without evidence of tumor recurrence.

OBJECTIVE: Gynecologists occasionally encounter synchronous endometrial and ovarian endometrioid carcinoma (SEO-EC) patients who show favorable prognosis than locally advanced or metastatic disease patients. This study aimed to elucidate prognostic factors of SEO-EC and identify patients who have a sufficiently low risk of recurrence without receiving adjuvant chemotherapy. METHODS: We retrospectively reviewed 46 patients with pathologically confirmed SEO-EC who underwent surgery at the National Cancer Center Hospital between 1997 and 2016. Immunohistochemical evaluation of DNA mismatch repair (MMR) protein expression were performed for both endometrial and ovarian tumors. Patient outcomes were analyzed according to clinicopathologic factors. RESULTS: From the multivariate analysis, cervical stromal invasion indicated a worse prognosis for progression-free survival (hazard ratio [HR]=6.85; 95% confidence interval [CI]=1.50–31.1) and overall survival (HR=6.95; 95% CI=1.15–41.8). Lymph node metastasis and peritoneal dissemination did not significantly affect survival. MMR deficiency was observed in 13 patients (28.3%), with both endometrial and ovarian tumors showing the same MMR expression status. MMR deficiency was not significantly associated with survival. Of 23 patients with lesions confined to only the uterine body and adnexa, only 2 had recurrence in the group receiving adjuvant therapy, while none of the 10 patients who did not receive adjuvant therapy had recurrence. CONCLUSION: SEO-EC patients with tumors localized to the uterine body and adnexa lesions had a low risk for recurrence and may not require adjuvant therapy. SEO-EC may have prognostic factors different from those of endometrial and ovarian cancer.

Background:
In Japan, neonates have typically been bathed in a bathtub immediately after birth because bathing is a custom for cleansing impurities. However, dry technique has been introduced into many institutions since 2000. There is little scientific evidence on the benefit or harmfulness of either method to neonatal skin, and consequently, opinion remains split on which method is superior.
Objective:
The purpose of the present study was to determine whether bathing or the dry technique of cleaning is better in maintaining skin health in the early neonatal period.
Methods:
Transepidermal water loss (TEWL) and skin pH, considered an index of skin barrier function, were measured in each group. Tumor necrosis factor (TNF)-alpha and interleukin (IL)-6, which are inflammatory cytokines released by keratinocytes, were measured by skin blotting.
Results:
TEWL and skin pH of neonates were lower with the dry technique than with bathing. The expression level of IL-6 and TNF-α in chest skin of neonates was higher with bathing than with the dry technique.
Conclusion
These results suggest that the dry technique may maintain skin health better than bathing in the early neonatal period.

OBJECTIVESTo investigate the association of smoking habits with blood pressure (BP) and intraocular pressure (IOP), and to examine whether the smoking-BP association is related to the IOP level.
METHODSThis study was conducted on the basis of a cross-sectional design using annual health check-up data during one-year between August, 1999 and August, 2000 for 611 middle and old-aged Japanese residents living in Ibaraki prefecture, Japan.
RESULTSAfter adjustment for age, gender, body mass index and alcohol intake score, the proportion of hypertensives, and the mean systolic and diastolic blood pressure (SBP and DBP) of the subjects without antihypertensive medications were the highest (50.4%, 129.6 mmHg and 75.9 mmHg, respectively) in the "smokers of 25 or more cigarettes per day with intraocular pressure (IOP)≥15 mmHg" of six subgroups crossed by three smoking categories (non-smokers, 1 to 24 cigarettes per day, and 25 or more cigarettes per day) and two IOP categories (less than 15 mmHg, and 15mmHg or greater). On the other hand, the adjusted proportion of hypertensives, and the adjusted mean SBP and DBP decreased with increasing smoking category in the individuals with less than 15 mmHg of the IOP (p for trend=0.028 for proportion of hypertensives 0.008 for the SBP, and 0.001 for the DBP, respectively).
CONCLUSIONSHeavy smoking may be specifically related to 'high BP accompanied by high IOP', although the BP may be inversely associated with smoking under the condition without high IOP.

OBJECTIVESThe aim of this study was to investigate the determinants of serum total homocysteine level (tHcy) in patients with type 2 diabetes mellitus (DM) according to sex.
METHODSA total of 1,276 Japanese, diabetics (n = 280) with a control group of non-diabetics (n = 996), were enrolled into the study from 2003 to 2005. This cross-sectional study was conducted for all the subjects, using personal data regarding clinical characteristics and lifestyle. Multiple regression analysis was performed to analyze the association of tHcy with selected factors.
RESULTSIn diabetic subjects, estimated glomerular filtration rate (eGFR) and serum creatinine levels (Cre), even those within the normal range, were strongly associated with tHcy after adjustment in both sexes; the standardized partial regression coefficient of eGFR for tHcy was -0.251, (p = 0.001) in diabetic men and -0.523, (p < 0.001) in diabetic women. Furthermore, the eGFR of the diabetics, except patients with nephropathy, also had significant association with tHcy in both sexes. Fasting plasma glucose levels and serum triglyceride levels were strongly associated with tHcy in diabetic men only. HbA1c was also associated with tHcy in diabetic men only, though not as significantly. Age and presence of hypertension were significantly associated with tHcy in women.
CONCLUSIONSThis study suggests that there are some differences in the factors associated with tHcy between diabetics and non-diabetics, and between the sexes. There is, therefore, circumstantial evidence that elevated tHcy should be evaluated clinically. Because tHcy was strongly associated with eGFR and Cre, even within the normal ranges, tHcy may have important implications regarding the microangiopathy of the kidney and atherosclerosis.
