The aim of this work was to comprehensively evaluate the cephalometric features in Japanese patients with obstructive sleep apnoea (OAS) and to elucidate the relationship between cephalometric variables and severity of apnoea.Forty-eight cephalometric variables were measured in 37 healthy males and 114 male OSA patients, who were classed into 54 non-obese (body mass index (BMI) <27 kg . m -2 , apnoea±hypopnoea index (AHI)=25.316.1 events . h -1) and 60 obese (BMI $27 kg . m -2 , AHI=45.628.0 events . h -1
Blood pressure (BP) variability is calculated as the standard deviation of ambulatory BP. Blood pressure variability is associated with the cardiovascular morbidity; however whether it is related to target organ damage is controversial. In this study we examined a possible relationship between the BP variability and left ventricular hypertrophy (LVH), and between BP variability and brachial-ankle pulse wave velocity (baPWV). The present study was conducted on 111 consecutive Japanese hypertensive patients who were hospitalized for the educational program in our hospital under stable sodium chloride intake (6 g/day). Blood pressure measurements were at 30-minute intervals all day. In a multivariable analysis adjusted with confounding factor, LVH was associated with 24-hour systolic BP (SBP), 24 hour diastolic BP (DBP), daytime SBP, daytime DBP, nighttime SBP, and nighttime DBP. Additionally, nighttime DBP variability was related to LVH. By the same method, baPWV as a dependent variable was related to 24-hour SBP and nighttime SBP. Furthermore, nighttime SBP variability was concerned with baPWV. The LVH was associated with not only BP level but also with nighttime DBP variability. The baPWV was also related not only to BP level but also to nighttime SBP variability.
The purpose of this study was to examine the possible difference in the 24-hr BP profile--including short-term BP variability, assessed as the standard deviation--between diabetic and non-diabetic hypertensives. We measured 24-hr ambulatory BP in 11 diabetic hypertensives (diabetic HT) and 10 non-diabetic hypertensives (non-diabetic HT) who were hospitalized for the educational program in our hospital and were under stable salt intake. Renal function and sleep apnea were also estimated. There were no significant differences in 24-hr systolic BP (141 mmHg vs. 135 mmHg, ns), daytime systolic BP (143 mmHg vs. 138 mmHg, ns), and nighttime systolic BP (135 mmHg vs. 130 mmHg, ns) between diabetic HT and non-diabetic HT. The values of 24-hr HR (69.7 beats/min vs. 65.2 beats/min, ns) and 24-hr HR variability (9.9 beats/min vs. 10.1 beats/min, ns) were also similar between the groups. Interestingly, diabetic HT had a significantly greater 24-hr systolic and diastolic BP variability than non-diabetic HT (18.2 mmHg vs. 14.5 mmHg, p < 0.05; 11.5 mmHg vs. 9.6 mmHg, p < 0.05, respectively). The values for creatinine clearance, urinary protein excretion, and apnea-hypopnea index were similar between the groups. Bivariate linear regression analysis demonstrated that fasting blood glucose was the primary determinant of 24-hr diastolic BP variability (r = 0.661, p < 0.01). Multiple stepwise regression analysis revealed that fasting blood glucose was a significant and independent contributor to 24-hr systolic BP variability (r = 0.501, p < 0.05). Taken together, these results demonstrate that BP variability is increased in diabetic hypertensives. Furthermore, it is possible that an elevation of fasting blood glucose may contribute to the enhanced BP variability in hypertensives.
We examined risk factors for coronary heart disease (CHD) by ambulatory blood pressure (BP) monitoring in 72 diabetic hypertensives who were hospitalized for the educational program. The patients were divided into two groups (CHD group, 19 subjects; and non-CHD group, 53 subjects) along with or without co-existing CHD. On ambulatory BP monitoring, no significant differences were found between the groups regarding BP values through the day. However, the CHD group had a significantly greater BP variability than non-CHD group. The result of logistic regression analysis demonstrated that nighttime systolic BP variability was an independent risk factor for CHD.
Continence following low anterior resection may be influenced by maximum resting pressure function of the internal anal sphincter; if it is injured during surgery, incontinence will occur. We may be able to foretell incontinence by using the predicted postoperative resting pressure formula, which is calculated by using preoperative resting pressure measurements and then determining the length of the remaining rectum.
ABSTRACT. An 11-month-old Japanese Black steer with chronic bloat underwent clinical and histological analyses. During the observation period, it showed normal appetite and fecal volume but persistent chronic bloat symptoms. Compared to controls, the steer's feces contained undigested large straws. Necropsy revealed normal rumen, reticulum, and abomasum but a small omasum. The rumen, reticulum, and abomasum mucosa was normal, with well-developed ruminal papillae. However, severe hypoplasia of the omasal laminae was observed along with hypoplasia reticular groove and ruminoreticular fold. The contents of the reticulum, omasum, and abomasums comprised undigested large sized hay particles. The omasum papillae showed no pathological abnormalities. This is a rare case of a steer with chronic bloat probably caused by severe hypoplasia of the omasal laminae. KEY WORDS: hypoplasia, Japanese Black steer, omasal laminae.
We report herein the case of a 65-year-old man with cirrhosis of the liver in whom a portal vein thrombus was found to be the cause of a marked elevation in serum alpha-fetoprotein (AFP). The patient presented with fever and abdominal pain, and a diagnostic work-up revealed a liver mass and an increased serum AFP concentration of 91,000 ng/ml. The mass gradually regressed, and the AFP concentration simultaneously decreased to 163 ng/ml. However, because hepatocellular carcinoma (HCC) could not be ruled out, a partial hepatectomy was performed. Histological examination of the resected specimen revealed a thrombus of the portal vein surrounded by the fibrosis associated with liver cirrhosis, but no neoplastic lesion was found. Thus, portal thrombus associated with liver cirrhosis might induce an extremely high level of AFP production.
