Efficacy and limitations of additional steroid pulse therapy in IgA nephropathy patients whose hematuria did not remit on tonsillectomy and protocol steroid pulse therapy.

BACKGROUND: Hematuria is the essential symptom of IgA nephropathy that has been suggested to be associated with long-term renal prognosis, Tonsillectomy and steroid pulse therapy (TSP), which is widely practiced in Japan, is effective for achieving hematuria remission. However, some cases are refractory to TSP, and additional steroid pulse therapy (SP) administered to these cases to achieve remission of hematuria. Nonetheless, the clinical significance of additional SP is unknown. METHODS: In this retrospective study, we enrolled 99 patients from Okubo Hospital whose hematuria persisted following TSP. Patients were divided into the hematuria remission and non-remission groups. A multivariate regression analysis was performed on the factors that contributed to hematuria remission. RESULTS: Following TSP, 103 of 403 patients (32.3%) did not achieve hematuria remission. Additional SP were performed in 99 of these patients, and remission of hematuria was achieved in 57 (57.6%). Patients with a greater degree of improvement in hematuria with TSP were significantly more likely to have remission of hematuria with additional SP (p = 0.0084*). Even in the hematuria non-remission group, both hematuria and proteinuria improved after additional SP. CONCLUSION: In IgA nephropathy, additional SP could induce hematuria remission and reduce proteinuria.

Effect of Nutrition Education on the Vegetable Intake of Residents in Okinawa.

Background: Increasing vegetable intake is recommended for promoting health in communities. This study investigated the effects of nutrition education on vegetable intake and the factors associated with changes in vegetable intake among residents of Okinawa. Methods and Results: Subjects (n=1,345; mean [±SD] age 56.8±14.6 years; 40.5% male) were recruited from among local residents participating in the Yui Kenko Project. Subjects completed the brief-type self-administered diet history questionnaire (BDHQ) and questionnaires on socioeconomic demographics and social capital. Subjects were divided into 2 groups according to residential area, namely south Okinawa (n=679), where local health promotion activities have been undertaken since the early 2000s, and central Okinawa (n=666). Survey results were fed back to each subject, and health lectures were then conducted at local community centers. After 1 year, the BDHQ was repeated to investigate changes in vegetable and nutritional parameters. After the intervention, residents of south Okinawa increased their crude and energy-adjusted vegetable intake (P<0.05), whereas residents of central Okinawa showed decreased vegetable intake (P<0.05). Univariable and multivariable regression models indicated that, in south Okinawa, participation in local health promotion activities and agreement with general trust were positively correlated with changes in energy-adjusted vegetable intake, whereas in central Okinawa no correlations were observed. Conclusions: The status of social capital should be taken into account when implementing initiatives to increase vegetable intake in communities.

Skin lesion of extranodal natural killer/T-cell lymphoma nasal type.

We report herein the case of an 81-year-old female patient who presented with poor feeding, various skin lesions, and pancytopenia. She finally received the diagnosis of extranodal natural killer/T-cell lymphoma nasal type (ENKTL-NT) without nasal lesions after four skin biopsies. Skin lesions of ENKTL-NT are usually nonspecific, making diagnosis based on cutaneous findings alone difficult. Hence, repeated biopsies, not only of the lesion, but also of the surrounding, normal tissue, are needed especially when the skin lesions are of uncertain etiology or intractable and accompanied by systematic symptoms or pancytopenia.

Pneumococcal perihepatitis due to hematogeneous dissemination.

Perihepatitis is mainly caused by a direct extension of pelvic inflammatory disease, in which the causative pathogen is typically Neisseria gonorrhoeae or Chlamydia trachomatis. We herein discuss the case of a 61-year-old female patient who presented with a fever and right upper quadrant pain. Perihepatitis was diagnosed by contrast-enhanced computed tomography. She had no previous history of sexual activity, genital symptoms, remarkable physical findings or examination results indicative of pelvic inflammatory disease or other diseases. A blood culture detected Streptococcus pneumoniae, leading to the suspicion of hematogeneous dissemination. The patient was therefore treated with the appropriate antimicrobials. While invasive pneumococcal disease mainly results in bacteremic pneumonia, meningitis or endocarditis, the present case showed that it can also lead to perihepatitis; a blood culture is therefore useful for clarifying the infection route and pathogens in perihepatitis if the patient has no past history of sexual activity, genital symptoms or physical or other findings indicative of pelvic inflammatory disease.

Trends in the incidence of stroke and cardiovascular risk factors on the isolated island of Okinawa: the Miyakojima study.

BACKGROUND: Rapid deterioration of cardiovascular risk control, especially obesity, has occurred in Okinawa; this may affect cardiovascular disease incidence, including stroke. METHODS: Cross-sectional field studies were conducted in 2 periods, 1988-1991 as the first period, and 2002-2005 as the second period, in the isolated island of Okinawa, Miyakojima. To evaluate population backgrounds related to cardiovascular risk factors, data from the health checkup programs conducted in 1987 and 2001 were surveyed. RESULTS: Total of 257 patients in the first period and 370 in the second were diagnosed with first-time stroke. The age-adjusted annual incidence rate of first-time stroke of the first and second periods was 124 and 144 per 100,000 standard population of Japan. The age-adjusted annual incidence rate showed an upward trend for brain infarction (50 to 73) and downward trend for brain hemorrhage (61 to 54); however, those trends were not significant. The health checkup surveys illustrated that blood pressure decreased in all age groups during the second survey period. However, the body mass index increased in patients aged 50 years or more. Fasting blood glucose levels of patients aged 30-79 years and non-HDL cholesterol levels of patients aged 50-79 years significantly increased. CONCLUSIONS: In Miyakojima, the incidence of first-time stroke and all of its subtypes did not change significantly between two periods, even though blood pressure decreased significantly in the second period. Metabolic deterioration may be associated with the upward trend in incidence of brain infarction.

Penicillin G-induced hemorrhagic cystitis with hydronephrosis.

Irritable urological symptoms with gross hematuria and bilateral lumbar pain developed when the patient received penicillin G for endocarditis. These symptoms were followed by renal insufficiency. A contrast-enhanced abdominal computed tomography (CT) scan revealed a thickened bladder wall, bilateral hydroureter and hydronephrosis, suggesting hemorrhagic cystitis complicated with urinary tract obstruction. Urine culture was negative. After discontinuation of penicillin G, all symptoms subsided and renal function recovered; hence, penicillin G seems to have been associated with hemorrhagic cystitis and acute kidney injury. Positive findings in the drug lymphocyte stimulation test (DLST) for penicillin G were consistent with this diagnosis.

Improvement of cardiac function after granulocyte-colony stimulating factor-mobilized peripheral blood mononuclear cell implantation in a patient with non-ischemic dilated cardiomyopathy associated with thromboangiitis obliterans.

Cardiac involvement is a rare complication with thromboangiitis obliterans (TAO). We report a 29-year-old man with TAO accompanied with non-ischemic dilated cardiomyopathy. He had no history of heart disease, but echocardiogram demonstrated diffuse hypokinesis and dilated left ventricle. Coronary angiography revealed no organic stenotic lesion. For limb salvage, he was treated with granulocyte-colony stimulating factor (G-CSF)-mobilized peripheral blood mononuclear cell (PBMNC) implantation on his right leg. Not only ischemic leg symptoms, but also plasma level of BNP and (123)I-metaiodobenzylguanidine scintigraphic parameters improved after 24 weeks. G-CSF-mobilized PBMNC implantation could be an effective approach to treating non-ischemic cardiomyopathy.

Effects of blood pressure levels on case fatality after acute stroke.

OBJECTIVE: We evaluated the relationship between admission blood pressure (BP) and early prognosis in patients with acute stroke in a single cohort. DESIGN: The subjects comprised 1004 cases of brain infarction and 1097 cases of brain hemorrhage, who were admitted to hospitals on the day of stroke onset. Death within 30 days after onset was evaluated in relation to admission BP levels. RESULTS: In brain infarction, a U-shaped relationship was found between BP levels and mortality rate, with a nadir at systolic blood pressure (SBP) of 150-169 mmHg and at diastolic blood pressure (DBP) of 100-110 mmHg. After adjustments for age and sex, the highest relative risks (RR) was observed in the lowest BP levels compared with nadir groups, and were 2.69 [95% confidence interval (CI), 1.43-5.07] in SBP and 3.49 (95% CI, 1.58-7.74) in DBP. In subjects with previous hypertension, the relationship between prognosis and SBP level shifted significantly toward higher pressure by about 10 mmHg compared with those without previous hypertension. In subjects with brain hemorrhage, the relationship between BP levels and mortality rate showed a J-shape in SBP and a U-shape in DBP. Highest BP levels had the poorest prognoses (>/= 230 mmHg in SBP, RR = 4.13, 95% CI = 2.45-6.94; >/= 120 mmHg in DBP, RR = 1.83, 95% CI = 1.11-3.04). CONCLUSION: Lower and higher BP after brain infarction and higher BP after brain hemorrhage were predictors for poor early prognosis. In subjects with brain infarction, patients with previous hypertension had better outcomes at higher admission BP level than did normotensive patients.
