Nitrotyrosine localization to dermal nerves in borderline leprosy.

BACKGROUND: Nerve damage is a common and disabling feature of leprosy, with unclear aetiology. It has been reported that the peroxidizing agents of myelin lipids-nitric oxide (NO) and peroxynitrite-are produced in leprosy skin lesions. OBJECTIVES: To investigate the localization of nitrotyrosine (NT)-a local end-product of peroxynitrite-in leprosy lesions where dermal nerves are affected by a granulomatous reaction. METHODS: We investigated by immunohistochemistry and immunoelectron microscopy the localization of the inducible NO synthase (iNOS) and NT in biopsies exhibiting dermal nerves from patients with untreated leprosy. RESULTS: There were abundant NT-positive and iNOS-positive macrophages in the borderline leprosy granulomas infiltrating peripheral nerves identified by light microscopy, S-100 and neurofilament immunostaining. Immunoelectron microscopy showed NT reactivity in neurofilament aggregates and in the cell wall of Mycobacterium leprae. CONCLUSIONS: Our results suggest that NO and peroxynitrite could be involved in the nerve damage following borderline leprosy.

Goitrogenesis during pregnancy and neonatal hypothyroxinaemia in a borderline iodine sufficient area.

OBJECTIVE: Severe iodine deficiency disorders (IDDs) may have been eradicated in many parts of the world, but milder forms still exist and may escape detection. We evaluated the impact of pregnancy on the maternal and fetal thyroid axis in Hong Kong, a coastal city in southern China with borderline iodine intake. DESIGN: A prospective study performed in a maternity hospital. PATIENTS: Two hundred and thirty pregnant women were prospectively studied and their neonates assessed at birth. MEASUREMENTS: Urine iodine concentration, thyroid function tests and thyroid volume (TV) by ultrasound were determined in the mothers during pregnancy and up to 3 months postpartum and in the neonates. RESULTS: Increased urinary iodine concentration was seen from first trimester onwards and the proportion of women having urine iodine concentration of < 0.4 micromol/l decreased from 11.3% in the first trimester to 4.7% in the third trimester. There was progressive reduction in circulating fT4 and fT3 concentrations and free thyroxine index (FTI) with increasing gestation and the percentage of women having subnormal levels at term were 53.2%, 61.1% and 4.8%, respectively. The serum TSH concentration during pregnancy doubled towards term. In the first trimester, multiparous women had significantly larger TV than the nulliparous women (P < 0.001). By the third trimester, TV had increased by 30% (range 3-230%) so that the goitre incidence was 14.1%, 21.8%, 25.9% during the three trimesters of pregnancy, and 24.3% and 21.9% at 6 weeks and 3 months postpartum (ANOVA, P < 0.05). The change in thyroid volume during pregnancy correlated positively with the change in thyroglobulin (r = 0.225, P < 0.002) and negatively with urinary iodine concentration (r = - 0.149, P < 0.02). Fourteen women with excessive thyroidal stimulation in the second trimester (defined as those with thyroglobulin (Tg) concentrations in the highest tertile and FTI in the lowest tertile) were found to have lower urine iodine concentrations and larger TV (both P < 0.005) throughout pregnancy, and their neonates had higher cord TSH (P < 0.05), Tg (P < 0.05) and slightly larger TV (P = 0.06) as compared to the findings in 216 pregnant women without evidence of thyroid stimulation. Seven neonates (50%) born to these women had subnormal fT4 levels at birth. CONCLUSION: In a borderline iodine sufficient area, pregnancy posed an important stress resulting in higher rates of maternal goitrogenesis as well as neonatal hypothyroxinaemia and hyperthyro- trophinaemia. An adequate iodization program is necessary to eliminate iodine deficiency disorders during pregnancy.

Regular audit of colposcopic biopsies from women with a mildly dyskaryotic or borderline cervical smear results in fewer cases of CINIII.

Two years after introducing mandatory review of cases in which the cervical smear was discrepant with subsequent colposcopic or histological finding, the predictive accuracy of a first abnormal smear and the need for treatment were analysed. The results were compared with performance figures prior to this form of audit policy. Over 12 months 415 women referred for colposcopy were studied. Three per cent of patients with a single borderline smear and 6% with mild dyskaryosis had cervical intraepithelial neoplasia grade III (CINIII) revealed in histopathological examinations after colposcopy. Only 25% with a borderline smear and 33% with mild dyskaryosis required treatment. Of women with moderate dyskaryosis, 18% had a biopsy showing CINIII and 46% were treated. Of women with severe dyskaryosis in their cervical smear, 61% were shown to have CINIII or invasive cancer on biopsy and 90% were treated. Regular audit improved cytological prediction of grade of epithelial abnormality found on biopsy, allowing accurate, safe surveillance for minor smear abnormalities.

Communicating mild and borderline abnormal cervical smear results: how and what are women told?

The way in which women are informed about borderline or mild smear results can have a significant psychological impact. By means of a questionnaire survey of general practices in Nottingham, England, this study audited the means by which abnormal smear results were normally communicated to subjects and analysed the content of these communications. Transmitting abnormal smear results, either by letter or by telephone call, was typically the responsibility of the practice nurse, and communications varied widely in informational content. We conclude that the method and content of communications imparting mild or borderline smear results differs between general practices, even within a small geographical area.

Antibodies to platelet-activating factor are associated with borderline hypertension, early atherosclerosis and the metabolic syndrome.

OBJECTIVE: Platelet-activating factor (PAF) is a phospholipid inflammatory mediator which is synthesized by a variety of cells, including monocytes and endothelial cells, and PAF can be retained in activated endothelial cell membranes. Furthermore, PAF-like lipids are produced in other phospholipid membranes as in oxidized LDL. Atherosclerosis is a chronic inflammation in the artery wall, but little is known about the role of immune reactions in the early stages of development of cardiovascular disease. In the present study we investigated if there are antibodies to PAF (aPAF) that may play a role in borderline hypertension and early atherosclerosis. DESIGN: Seventy-three men with borderline hypertension (BHT) and 73 age-matched normotensive (NT) men (diastolic blood pressure 85-94 and <80 mmHg, respectively) were recruited from a population screening programme. Antibody levels were determined by use of ELISA. Carotid intima-media (IM)-thickness and atherosclerosis was determined by B-mode ultrasonography. RESULTS: BHT men had 49.3% higher aPAF levels of IgG class than NT controls (P = 0.0007). Antibodies to the biologically inactive lysoPAF did not differ between BHT and NT group. aPAF levels were associated with IM-thickness in the left (P = 0.02) and right (P = 0.009) carotid artery. Furthermore, aPAF levels were enhanced in individuals with the metabolic syndrome (n = 44) as compared to those without (n = 102; P = 0.009), and also significantly associated with insulin levels (P = 0.02) and insulin resistance (P = 0.02). CONCLUSIONS: aPAF antibodies may reflect early vascular changes and thus serve as novel markers for disease, and they may also be pathogenic, by eliciting an inflammatory reaction in the vascular wall.

The role of pentoxifylline in the treatment of erectile dysfunction due to borderline arterial insufficiency.

OBJECTIVE: To investigate the effects of pentoxifylline on penile blood flow and potency in patients with erectile dysfunction due to borderline arterial insufficiency. PATIENTS AND METHODS: Following a routine diagnostic evaluation, 36 patients with borderline arterial disease diagnosed using penile duplex ultrasonography were included in the study. Of these patients, 20 (mean age 54 years, range 40-66) received 1.2 g of pentoxifylline daily, divided into three doses orally, for 2 months and 16 (mean age 54 years, range 34-65) received a placebo. Peak systolic velocities (PSVs) before and after the treatment were compared with those in patients receiving a placebo. The clinical improvement in erectile function was also evaluated. RESULTS: Twelve of 20 patients receiving pentoxifylline had an increase in PSV at the end of the treatment period. The mean change in PSV achieved by pentoxifylline treatment (6.25 cm/s) was significantly higher than that achieved by the placebo (0.38 cm/s). Seven patients had a positive response (successful coitus achieved after treatment with pentoxifylline). No serious side-effects occurred. CONCLUSION: Pentoxifylline was well tolerated and could increase penile arterial inflow, shown objectively as an increase in PSV on penile duplex ultrasonography. These findings should encourage further studies of the efficacy of pentoxifylline in the treatment of impotence.

Outcome of fetuses with isolated borderline unilateral ventriculomegaly diagnosed at mid-gestation.

OBJECTIVE: To evaluate the outcome of fetuses with isolated borderline, unilateral ventriculomegaly. DESIGN: A retrospective survey was conducted at four perinatal centers in Israel. SUBJECTS AND METHODS: Only fetuses with one ventricular width of > or = 11 mm and the other < 10 mm were included in the study. In all cases, the difference of the ventricular width between the two ventricles was > 2.4 mm (two standard deviations). Fetuses with other malformations, chromosomal abnormalities, or those with evidence of in utero infection, were not included in the study. RESULTS: Unilateral ventriculomegaly was found in 27 subjects (after excluding one case with unilateral ventriculomegaly and Down's syndrome). The mean width of the enlarged ventricle was 11.7 +/- 0.9 mm, while the other normal ventricle was 7.2 +/- 0.9 mm. The mean gestational age at diagnosis of the unilateral ventriculomegaly was 23.6 +/- 2.7 weeks. In one case, pregnancy was terminated, and pathological examination of the fetal brain failed to detect any structural abnormality. Twenty-five patients delivered at term and only one at 34 weeks' gestation. The neurological development in all 25 fetuses was normal, and one fetus had petit mal seizures. CONCLUSION: Fetuses with isolated, borderline unilateral ventriculomegaly, but without other abnormalities, have a good neurological outcome.

The management of borderline epithelial tumors of the ovary.

The histopathological diagnosis and treatment of borderline epithelial tumors of the ovary (BTO) still pose problems to both pathologists and gynecologists. BTO is a disease of younger, fertile females and generally has an excellent prognosis. A minority of patients, however, succumb to this disease. A review of the literature is given addressing aspects of epidemiology, histology, treatment and prognosis, resulting in a proposal for the management of serous and mucinous borderline tumors of the ovary.

A randomized, double-blind, placebo-controlled study of oral vitamin B12 supplementation in older patients with subnormal or borderline serum vitamin B12 concentrations.

OBJECTIVES: To determine the effect of small doses of oral cyanocobalamin supplements in older patients with low or borderline serum vitamin B12 concentrations but no other evidence of pernicious anemia (PA). DESIGN: Randomized, double-blind, placebo-controlled study assessing the efficacy of oral cyanocobalamin 10 microg and 50 microg daily for 1 month. SETTING: Two geriatric hospitals in the North Western Health Care Network, Melbourne, Australia. PARTICIPANTS: Thirty-one inpatients with serum vitamin B12 levels between 100 and 150 pmol/L, without PA, other malabsorption disorders, or progressive neurological or terminal illness. The mean age was 81.4 years. INTERVENTION: After informed consent, a medical and drug history was taken and the Mini-Mental State Examination (MMSE) completed. A dietitian made assessment of oral cobalamin intake. Blood was taken for serum vitamin B12, serum and red cell folate assay, full blood examination, fasting serum gastrin, parietal and intrinsic factor antibodies, fasting serum homocysteine, and creatinine. Patients were then randomized to receive 10 microg oral cyanocobalamin, 50 microg oral cyanocobalamin, or placebo treatment for 1 month, after which the investigations and clinical examinations were repeated. MEASUREMENTS: Percentage change in the level of vitamin B12, homocysteine, folate, and red cell parameters and absolute changes in MMSE were calculated and compared between groups. The groups were compared on the number of responders who improved their level of B12 by 20%. Chi-square calculations on changes in serum vitamin B12 concentration were also performed. RESULTS: Mean serum vitamin B12 +/- standard deviation improved by 51.7 +/- 47.1% in the 50-microg group, 40.2 +/- 34.4% in the 10-microg group, and 11.7 +/- 24.5% in the placebo group. The change in the 50-microg cyanocobalamin group was significantly greater than that in the placebo group (P=.044). The change in the 10-microg cyanocobalamin group was not significantly different from that in the placebo group (P=.186). Eight of 10 subjects in each treatment group were classified as responders, compared with two of 11 in the placebo group (P=.004). Homocysteine levels fell in patients receiving cyanocobalamin, but this fall failed to reach statistical significance. There were no significant changes in the other parameters measured. CONCLUSION: Cyanocobalamin supplementation of 50 microg but not 10 microg daily produced a significant increase in serum vitamin B12. This result has implications for the management of patients with subnormal or borderline serum vitamin B12 concentrations and for food fortification with vitamin B12.

Glucose disposal rates calculated from 60- to 90-minute isoglycemic hyperinsulinemic glucose clamp correlate with cardiovascular risk factors in borderline hypertensive young men.

The hyperinsulinemic glucose clamp is generally performed for at least 120 minutes, due to assumptions of steady-state. We were interested in relationships between glucose disposal rate (GDR) and cardiovascular risk factors, rather than a standard measure of insulin sensitivity per se. Therefore, we analyzed 120-minute clamps performed on borderline hypertensive, but otherwise healthy young men (n = 19). GDR was calculated at different time points and related to baseline cardiovascular risk factors and responses to a mental stress test (MST). The 60-, 90-, and 120-minute GDR correlated significantly with serum high-density lipoprotein (HDL) cholesterol (r=.59, r=.50, and r=.53, respectively), heart rate (HR) during MST (r = -.65, r = -.64, and r = -.58, respectively) and plasma epinephrine (Epi) (r = -.55, r= -.58, and r = -.56, respectively) and norepinephrine (NE) (r = -.52, r = -.49, and r = -.48, respectively) 1 minute after announcement of the MST (all P <.05). Although not statistically significant at all time points, similar relationships were observed between GDR and resting HR, systolic blood pressure (BP) at rest and during mental stress, body mass index (BMI), serum total cholesterol (Chol), serum triglycerides (TG), and blood hemoglobin (HgB), with remarkable consistency from about 40 to 50 minutes onwards. HDL cholesterol and Epi remained independent in stepwise multiple regression analyses with the 60-, 90-, and 120-minute GDR as dependent variables (all P <.05). We suggest that 60- to 90-minute glucose clamps may provide information about the relationship between insulin sensitivity and various cardiovascular risk factors in borderline hypertensive young caucasian men.

[Borderline tumors of the ovary. New aspects on morphologic prognosis determination].

Epithelial tumours of the ovary with a tumour status between benign and malignant are classified as borderline tumours (BOT). They are particularly frequent in women between 30 and 40 years of age, emphasising the need for effecting a therapy directed at preserving fertility. To keep the risk of this therapy at a minimum it is imperative to effect accurate determination of the prognosis on the basis of an examination of the histological preparation. Conventional histology is insufficient for this purpose, thus requiring the use of additional morphological methods. In the present study the DNA of the cell nucleus was determined via quantitative cytophotometry and also via several tumour or differentiating markers by immunohistology, in healthy ovaries, 10 benign and 20 malignant ovarian tumours and in 20 borderline tumours (BOT). The DNA histograms of the tumours classified histologically as BOT, yielded distribution patterns pointing towards a benign, proliferative or malignant potency of the tumours without a correlation to conventional histology being present in each case. Immunohistological identification of the carcinoembryonal antigen (CEA) and of the blood group substances (A, B, Lewis, Lewis) produced characteristic distribution patterns which correlated with the tendency to proliferation in DNA cytophotometry. To achieve relevant determination of prognosis of BOT in individual cases, conventional histology should be complemented by additional examinations using DNA cytophotometry and immunhistology as diagnostic tools.

Decreased large artery distensibility in borderline hypertension is related to increased in vivo low-density lipoprotein oxidation.

The present study tested the hypothesis that reduced arterial elasticity seen in hypertension is related to increased oxidation of LDL. Fifteen men with borderline hypertension (BHT), with blood pressure values classified as high normal (systolic blood pressure 130-140 mmHg or diastolic blood pressure 85-89 mmHg) were included. The control group comprised 22 men with normal blood pressure values (<135/80 mmHg) matched for age, body size and LDL-cholesterol level. Distensibility of aorta was measured using magnetic resonance imaging, and distensibility of the common carotid artery using ultrasound. Baseline LDL diene conjugation was used as a marker for ox-LDL. Aortic and carotid distensibilities were lower in the BHT men than in controls (1.4 +/- 0.6 vs. 1.9 +/- 0.6%/10 mmHg, p<0.05 for aortic distensibility; 2.9 +/- 0.9 vs. 3.6 +/- 0.6%/10 mmHg, p<0.05 for carotid distensibility). Ox-LDL was significantly higher in the BHT men than in controls (44 +/-15 vs. 28 +/- 8 micromol/L, p<0.01). In univariate analysis, ox-LDL associated with aortic distensibility (r=-0.43, p<0.05). In multivariate analysis, the differences in distensibilities between the groups disappeared when the values were adjusted for ox-LDL. These data show decreased arterial elasticity and increased LDL oxidation in young men with borderline hypertension, and suggest that oxidative modification of LDL particles may play a pathophysiological role in the development of reduced arterial distensibility in hypertension.

Ouabain-binding and 86rubidium-uptake in lymphocytes of normal and borderline hypertensive subjects.

In borderline hypertensives cellular sodium concentration seems to be increased, indicating that cellular abnormalities are present in the early course of essential hypertension. In order to study the mechanisms underlying this finding the number of sodium/potassium pump sites and the cation pump activity were studied in lymphocytes of nine borderline hypertensives (27 (20-36) years) and nine controls (28 (20-36) years). Maximum 3H-ouabain binding and 86Rb-uptake were taken as measures of the number of pump sites and cation pump activity, respectively. The median number of sodium/potassium pump sites was 49.6 X 10(3) molecules/cell in the BH group compared to 32.4 X 10(3) in the control group (P less than 0.01). Median 90 min 86Rb-uptakes were 54.0 pmol/10(6) cells in BH subjects and 39.4 in controls (P less than 0.10). The increased number of sodium/potassium pump sites and the tendency to increased cation pump activity in lymphocytes of BH subjects in vitro may be interpreted as an adaptive change possibly induced by a circulating natriuretic substance.

Endoluminal gastroplication for treatment of patients with classic gastroesophageal reflux symptoms and borderline 24-h pH studies.

BACKGROUND: Patients with classic gastroesophageal reflux disease (GERD) symptoms and borderline 24-h pH studies are not considered to be good candidates for surgical fundoplication. Endoluminal gastroplication (ELGP) is a new endoscopic treatment for patients with GERD. The aim of this study was to evaluate the efficacy of ELGP in these patients. METHODS: Patients with heartburn, regurgitation symptoms and a DeMeester score of less than 30 were studied. ELGP involved placement of two or three plications within 2 cm of the gastroesophageal junction. Clinical outcomes measured were heartburn symptom score (HSS), regurgitation frequency score (RFS) and medication use. RESULTS: Twenty-five patients (11 M, 14 F, mean age of 51 years) had a medication use of 11.5 doses of proton-pump inhibitors per week prior to ELGP. Average lower esophageal sphincter pressure measured 15 +/- 8 mmHg, and average DeMeester score was 18 +/- 8. Nine patients had hiatal hernias and 11 had esophagitis. Twenty-four patients were available for a mean follow-up of 12 months. HSS significantly decreased from 48 to 17 (P < 0.01) and RFS was reduced from 1.8 to 0.7 (P < 0.01). Proton-pump inhibitor use was 5.3 doses per week (P < 0.01) post-ELGP; 12 patients (50%) were off medications, 3 (13%) had a 50% reduction in medication use, and in 9 (37%) there was no change. Complications were bleeding in one patient and aspiration pneumonia in another patient. CONCLUSIONS: Endoluminal gastroplication provides symptomatic relief for patients with classic GERD symptoms despite medical therapy and borderline 24-h pH studies.

Increased forearm blood flow during glucose clamp is related neither to insulin sensitivity nor to hyperinsulinemia in borderline hypertensive young men.

It is controversial whether raised insulin within the physiological concentration range increases forearm blood flow (FBF). The aim of the present study was therefore to examine the effect of the isoglycemic hyperinsulinemic glucose clamp procedure on FBF and to relate the increase to the glucose disposal rate (GDR), i.e. insulin sensitivity. Borderline hypertensive young men were examined with the clamp technique or received saline infusion, and FBF was measured using plethysmography. It is of particular interest to study this group of subjects because their GDR correlates to a number of metabolic and hemodynamic variables, and these subjects hyperreact to stressful stimuli. There was no correlation between deltaFBF during clamp and GDR (r = -0.002, p = 0.99, n = 28). While serum insulin increased from 107 +/- 5 to 628 +/- 31 pmol/l in the hyperinsulinemic group and remained unchanged (135 +/- 11 vs 116 +/- 11 pmol/l) in the saline group, FBF increased from 3.5 +/- 0.3 to a maximum of 5.1 +/- 0.4 ml/min/100 ml (p < 0.001, n = 28) and from 2.8 +/- 0.5 to a maximum of 4.5 +/- 0.5 ml/min/100 ml (p = 0.01, n = 8), respectively. The increase in FBF (delta%) was similar in the two groups (p = 0.9). Thus, we could not demonstrate any relationship between insulin sensitivity and increments in FBF during hyperinsulinemic glucose clamp in borderline hypertensive young men. The moderate increases in FBF during insulin infusion with serum concentrations within the physiological range seem to be time-dependent and not caused by hyperinsulinemia.

Medically supervised water-only fasting in the treatment of borderline hypertension.

BACKGROUND: Hypertension-related diseases are the leading causes of morbidity and mortality in industrially developed societies. Surprisingly, 68% of all mortality attributed to high blood pressure (BP) occurs with systolic BP between 120 and 140 mm Hg and diastolic BP below 90 mm Hg. Dietary and lifestyle modifications are effective in the treatment of borderline hypertension. One such lifestyle intervention is the use of medically supervised water-only fasting as a safe and effective means of normalizing BP and initiating health-promoting behavioral changes. METHODS: Sixty-eight (68) consecutive patients with borderline hypertension with systolic BP in excess of 119 mm Hg and diastolic BP less than 91 mm Hg were treated in an inpatient setting under medical supervision. The treatment program consisted of a short prefasting period (approximately 1-2 days on average) during which food consumption was limited to fruits and vegetables followed by medically supervised water-only fasting (approximately 13.6 days on average). Fasting was followed by a refeeding period (approximately 6.0 days on average). The refeeding program consisted of a low-fat, low-sodium, plant-based, vegan diet. RESULTS: Approximately 82% of the subjects achieved BP at or below 120/80 mm Hg by the end of the treatment program. The mean BP reduction was 20/7 mm Hg, with the greatest decrease being observed for subjects with the highest baseline BP. A linear regression of BP decrease against baseline BP showed that the estimated BP below which no further decrease would be expected was 96.0/67.0 mm Hg at the end of the fast and 99.2/67.3 mm Hg at the end of refeeding. These levels are in agreement with other estimates of the BP below which stroke events are eliminated, thus suggesting that these levels could be regarded as the "ideal" BP values. CONCLUSION: Medically supervised water-only fasting appears to be a safe and effective means of normalizing BP and may assist in motivating health-promoting diet and lifestyle changes.

Laparoscopically-assisted hysterectomy for the management of a borderline ovarian tumor: a case report.

Borderline ovarian tumors account for 4% of ovarian neoplasms, an incidence which remains constant despite advancing age. Management for younger women can be unilateral oophorectomy, although simple hysterectomy with bilateral salpingo-oophorectomy is more appropriate for women beyond childbearing age. The authors report a laparoscopic approach to a case of borderline ovarian tumor.

Ovarian micropapillary serous borderline tumors. Clinicopathologic features and outcome of seven surgically staged patients.

We report the clinicopathologic findings for 7 patients with completely staged ovarian micropapillary serous borderline tumors (MSBTs) to further clarify tumor behavior. None of the MSBTs had microinvasion in the ovarian neoplasm. The MSBT pattern constituted 25% to almost all of the neoplasm. Four were bilateral, and 6 involved the ovarian surface. Five patients had peritoneal implants; 2 were invasive, and 3 were noninvasive MSBTs. Distribution of stages among patients was as follows: IA, 1; IC, 1; IIC, 2; IIIB, 2; and IIIC, 1. Median follow-up was 8.5 years. Four patients were alive and well at the last follow-up visit, including 1 patient with stage IIIC (lymph node metastases) disease who had noninvasive implants (12 years after surgery). One patient who was free of disease died of complications of chemotherapy and abdominal surgery. Two patients died of intra-abdominal neoplastic growth (stages IIC and IIIB) 5 and 9 years after surgery, respectively; both had invasive implants. Without invasive peritoneal implants, MSBTs seem to behave as similar staged nonmicropapillary serous borderline tumors without invasive peritoneal implants. With invasive peritoneal implants, they seem to behave as low-grade carcinomas. Pathologists should recognize MSBT as a neoplasm that can have adverse prognostic features, including invasive peritoneal implants.
