Abstract
BACKGROUND Higher leptin and lower adiponectin levels have been linked to progressing systemic inflammation and diseases of aging. Among older adults with obesity and an inflammatory conditions, we quantified effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) supplementation on leptin, adiponectin, and the leptin-to-adiponectin ratio (LAR). We also examined associations among adipokine and cytokine levels. METHODS Using a randomized, double-blind, placebo-controlled design, participants (mean age 61.3 ± 2.1) received 1.5 g EPA + 1.0 g DHA (n = 14) or mineral oil (n = 18) daily. Plasma adipokine and cytokine levels were quantified by electrochemiluminescence at all study intervals. RESULTS While no between-group differences were detected, there was a reduction in the LAR (by 23%, p=.065) between weeks 4 and 8 among the EPA+DHA group. Adiponectin levels were negatively associated with IL-1β levels at week 4 (p=.02) and TNF-α levels at week 8 (p=.03). CONCLUSION Potential benefits of EPA+DHA supplementation among aging populations warrant further study.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
BACKGROUND Crohn's disease (CD) places a substantial burden on healthcare systems, with the majority of costs arising from hospitalisation and surgery. AIM To evaluate the 'real-world' clinical effectiveness, impact on healthcare utilisation and cost of infliximab for the treatment of CD in UK practice. METHODS A non-interventional, retrospective analysis of medical records from patients with CD treated with infliximab at 18 hospital centres across the UK. The primary objective was to compare cumulative clinical outcomes and healthcare resource utilisation for the 0- to 24-month post-infliximab period with the 12 months preceding infliximab treatment. Predefined outcomes included the number of elective surgical procedures, hospitalisations and healthcare provider consultations. Costs associated with healthcare utilisation were collected from the perspective of the UK National Health Service (NHS). RESULTS The study involved 380 patients. Infliximab significantly reduced the mean number of elective (from 0.18 to 0.11; P = 0.0035) and non-elective (from 0.46 to 0.29; P < 0.0001) hospitalisations, and the number of consultations with gastroenterologists, gastrointestinal surgeons and radiologists (from 4.0 to 3.5, from 0.7 to 0.5 and from 0.5 to 0.2, respectively; all P < 0.001); all decreases were associated with significant cost reductions. The mean number of elective surgical procedures (including correction of severe anal fistulae and abscess drainage) was significantly reduced. CONCLUSIONS The observed reductions in numbers of hospitalisations, surgical procedures and consultations with healthcare professionals are key indicators of the clinical effectiveness of infliximab for the treatment of CD. These benefits result in overall decreases in healthcare resource utilisation, which translate into cost savings for the NHS.

Abstract
BACKGROUND There is no international agreement on scoring systems used to measure disease activity in ulcerative colitis, nor is there a validated definition for disease remission. AIM To review the principles and components for defining remission in ulcerative colitis and propose a definition that will help improve patient outcomes. METHODS A review of current standards of remission from the perspective of clinical trials, guidelines, clinical practice and patients was conducted by the authors. Selected literature focused on the components of a definition of remission, the utility of a definition and treatment strategies, based on current definitions. RESULTS Different definitions of remission affect the assessment of outcome and make it difficult to compare trials. In the clinic, endoscopy is rarely used to confirm remission, because mucosal healing has only recently begun to be related to the duration of subsequent remission in a way that will affect clinical practice. Histopathology may be the ultimate arbiter of mucosal healing. There is no agreement on the definition of remission in current guidelines. Patient-defined remission may predict endoscopic remission, but has yet to be shown to predict duration of remission. CONCLUSIONS A standard based on clinical symptoms and endoscopy is proposed. Histopathology is a third dimension of remission that may have prognostic value. The definition of remission should help predict long-term outcome. The expectations of patients and their physicians need to be raised, as the goal of treatment of active ulcerative colitis should be to induce remission.

Abstract
AIMS/HYPOTHESIS The teratogenic consequences of angiotensin-converting enzyme inhibitors angiotensin receptor blockers (ARBs) during the second and third trimesters of pregnancy are well described. However, the consequences of exposure during the first trimester are unclear, especially in diabetes. We report the experience from DIRECT (DIabetic REtinopathy and Candesartan Trials), three placebo-controlled studies designed to examine the effects of an ARB, candesartan, on diabetic retinopathy. METHODS Over 4 years or longer, 178 normotensive women with type 1 diabetes (86 randomised to candesartan, 32 mg once daily, and 92 assigned to placebo) became pregnant (total of 208 pregnancies). RESULTS More than half of patients were exposed to candesartan or placebo prior to or in early pregnancy, but all discontinued it at an estimated 8 weeks from the last menstrual period. Full-term pregnancies (51 vs 50), premature deliveries (21 vs 27), spontaneous miscarriages (12 vs 15), elective terminations (15 vs 14) and other outcomes (1 vs 2) were similar in the candesartan and placebo groups. There were two stillbirths and two 'sick babies' in the candesartan group, and one stillbirth, eight 'sick babies' and one cardiac malformation in the placebo group. CONCLUSIONS/INTERPRETATION The risk for fetal consequences of ARBs in type 1 diabetes may not be high if exposure is clearly limited to the first trimester. Long-term studies in fertile women can be conducted with ARBs during pregnancy, provided investigators diligently stop their administration upon planning or detection of pregnancy. TRIAL REGISTRATION ClinicalTrials.gov DIRECT-Prevent 1 NCT00252733; DIRECT-Protect 1 NCT00252720; DIRECT-Protect 2 NCT00252694. FUNDING The study was funded jointly by AstraZeneca and Takeda.

Abstract
OBJECTIVE To study the association between baseline retinal microaneurysm score and progression and regression of diabetic retinopathy, and response to treatment with candesartan in people with diabetes. METHODS This was a multicenter randomized clinical trial. The progression analysis included 893 patients with Type 1 diabetes and 526 patients with Type 2 diabetes with retinal microaneurysms only at baseline. For regression, 438 with Type 1 and 216 with Type 2 diabetes qualified. Microaneurysms were scored from yearly retinal photographs according to the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol. Retinopathy progression and regression was defined as two or more step change on the ETDRS scale from baseline. Patients were normoalbuminuric, and normotensive with Type 1 and Type 2 diabetes or treated hypertensive with Type 2 diabetes. They were randomized to treatment with candesartan 32 mg daily or placebo and followed for 4.6 years. RESULTS A higher microaneurysm score at baseline predicted an increased risk of retinopathy progression (HR per microaneurysm score 1.08, P < 0.0001 in Type 1 diabetes; HR 1.07, P = 0.0174 in Type 2 diabetes) and reduced the likelihood of regression (HR 0.79, P < 0.0001 in Type 1 diabetes; HR 0.85, P = 0.0009 in Type 2 diabetes), all adjusted for baseline variables and treatment. Candesartan reduced the risk of microaneurysm score progression. CONCLUSIONS Microaneurysm counts are important prognostic indicators for worsening of retinopathy, thus microaneurysms are not benign. Treatment with renin-angiotensin system inhibitors is effective in the early stages and may improve mild diabetic retinopathy. Microaneurysm scores may be useful surrogate endpoints in clinical trials.

Abstract
OBJECTIVE To examine the mortality of type 1 diabetes (T1D) in two countries with very different health care systems using two population-based registries of childhood-onset T1D one in Havana (HA), Cuba, and the other in Allegheny County (AC), USA. RESEARCH DESIGN AND METHODS Cases diagnosed with T1D between 1965 and 1980 in HA and between 1965 and 1979 in AC were included. Follow-up started with diagnosis in each individual and ended as of 1 January 1991, or with death. Life-table analyses were used to examine the mortality rates in both populations by duration of diabetes. RESULTS Cumulative mortality by January 1991 in HA (14% in males and females, respectively) was higher than in AC (7% in males and 9% in females) for both genders (males, p=0.0005; females, p=0.0491). Mortality rates were considerably higher in HA for both men and women than in AC however, among females confidence intervals overlapped. Overall mortality rate for Caucasians (AC) was significantly lower than that for African-Americans (AC) or Hispanics (HR). An analysis of causes of death showed a greater proportion of deaths attributed to nephropathy (48.6%) in HA while acute complications (36%) and infections (27%) were more frequent in AC. CONCLUSIONS This study shows a two-fold greater mortality among people with childhood-onset T1D in Havana, Cuba, than in Allegheny, USA. Different strategies may be needed to increase survival among those with type 1 diabetes in the USA and Cuba.

Abstract
British Society of Gastroenterology guidelines recommend that all patients with ulcerative colitis should receive long-term therapy with a 5-aminosalicylic acid compound to maintain remission. Recent studies have shown that time spent in remission is longer when the maintenance dose is increased from 1.2 to 2.4 g/day, with patients with extensive disease benefiting most from an increase with dosage. A retrospective analysis also found that the frequency of relapse was lower in patients taking more than the median dose of 5-aminosalicylic acid (1.6 g/day) compared with those taking less than the median dose. Similarly, when 5-aminosalicylic acids are used to induce remission, continuing the induction dosage for an extra 4 weeks prolongs remission and reduces the frequency of relapse. However, patients rarely comply fully with the prescribed dose regimen, which can lead to effective under-dosing. The recent discovery that 5-aminosalicylic acids may act in ulcerative colitis by activating peroxisome proliferator-activated receptor-gamma, a nuclear receptor that plays a role in the control of cell proliferation and apoptosis, has given new impetus to the idea that long-term therapy with 5-aminosalicylic acid may reduce the risk of colorectal cancer. Epidemiological studies are beginning to provide evidence to support this view. Accumulating evidence suggests that the next revision of the clinical guidelines should suggest life-long doses of 5-aminosalicylic acid of > or =2 g/day for maintenance of remission in patients with ulcerative colitis.

Abstract
We prospectively assessed the implementation of venous thromboembolism (VTE) prophylaxis guidelines and the impact of grand round presentation of the data in changing clinical practice. Two NHS teaching hospitals were studied for 24 months from January 2003. Patients were risk stratified according to the THRIFT (thromboembolic risk factor) consensus group guidelines and compared with the recommendations of the THRIFT and ACCP (American College of Chest Physicians) consensus groups. Six months following presentation of the initial results, a further analysis was made to assess changes in clinical practice. 1128 patients were assessed of whom 1062 satisfied the inclusion criteria for thromboprophylaxis. 89% of all patients were stratified as having high or moderate risk of developing VTE. Of these only 28% were prescribed some form of thromboprophylaxis-4% received the THRIFT-recommended and 22% received the ACCP-recommended thromboprophylaxis. The vast majority (72%) received no thromboprophylaxis at all. Reassessment, following data presentation at grand rounds, showed a significant increase to 31% inpatients receiving THRIFT (P<0.0001) and ACCP (P=0.002) recommended thromboprophylaxis. However,the proportion of patients receiving no form of prophylaxis barely changed (72% to 69%: P=0.59). We found a gross underutilization of thromboprophylaxis in hospitalized medical patients. A simple grand-round presentation of the data and recommended guidelines to clinicians significantly increased the proportion of patients receiving recommended thromboprophylaxis but did not increase the overall proportion of patients receiving it. We therefore conclude that a single presentation of guidelines is not enough to achieve the desired levels. Such presentations may only serve to make DVT (deep venous thromboembolism) aware clinicians prescribe prophylaxis more accurately.

Abstract
The highly polymorphic nonclassical MHC class I chain-related (MIC) genes MICA and MICB encode stress inducible glycoproteins expressed on a variety of epithelial cells including intestinal cells. Interaction with the receptor NKG2D is likely to provide an important costimulatory signal for activation and proliferation of NK cells, activated macrophages and CD8 alphabeta and gammadelta T cells. Fifty-four MICA and 17 MICB alleles have been described to date. Although the functional significance of this polymorphism is not known, the high degree of nonconservative substitution, concentration to the putative ligand-binding site and recent observation that different MICA alleles bind to NKG2D with varying affinity has generated much interest. The MIC genes are attractive functional and positional candidate genes for inflammatory bowel disease susceptibility as a consequence of their position in the HLA region and expression on the gastrointestinal epithelium. We developed a robust, high-resolution PCR-SSP genotyping method that can be incorporated into the standard 'Phototyping' system and which effectively identifies 46 of 54 MICA alleles, and all 17 MICB alleles. We applied this system in combination with microsatellite genotyping of the exon 5 variable number of tandem repeats (VNTR) to the investigation of genetic susceptibility to the inflammatory bowel diseases, ulcerative colitis and Crohn's disease. We studied 248 patients with Crohn's disease, 329 with ulcerative colitis and 354 ethnically matched controls. Linkage disequilibrium patterns between HLA-B, MICA and MICB are presented. Analysis by individual allele or by multilocus haplotype failed to identify any significant disease associations.

Abstract
OBJECTIVE The Oral Health Science Institute at the University of Pittsburgh has completed a cross-sectional epidemiologic study of 406 subjects with type 1 diabetes and 268 control subjects without diabetes that assessed the associations between oral health and diabetes. This report describes the prevalence of dry-mouth symptoms (xerostomia), the prevalence of hyposalivation in this population, and the possible interrelationships between salivary dysfunction and diabetic complications. STUDY DESIGN The subjects with diabetes were participants in the Pittsburgh Epidemiology of Diabetes Complications study who were enrolled in an oral health substudy. Control subjects were spouses or best friends of participants or persons recruited from the community through advertisements in local newspapers. Assessments of salivary function included self-reported xerostomia measures and quantification of resting and stimulated whole saliva flow rates. RESULTS Subjects with diabetes reported symptoms of dry mouth more frequently than did control subjects. Salivary flow rates were also impaired in the subjects with diabetes. Regression models of potential predictor variables were created for the 3 self-reported xerostomia measures and 4 salivary flow rate variables. Of the medical diabetic complications studied (ie, retinopathy, peripheral and autonomic neuropathy, nephropathy, and peripheral vascular disease), only neuropathy was found to be associated with xerostomia and decreased salivary flow measures. A report of dry-mouth symptoms was associated with current use of cigarettes, dysgeusia (report of a bad taste), and more frequent snacking behavior. Xerogenic medications and elevated fasting blood glucose concentrations were significantly associated with decreased salivary flow. Resting salivary flow rates less than 0.01 mL/min were associated with a slightly higher prevalence of dental caries. Subjects who reported higher levels of alcohol consumption were less likely to have lower rates of stimulated salivary flow. CONCLUSIONS Subjects with type 1 diabetes who had developed neuropathy more often reported symptoms of dry mouth as well as symptoms of decreased salivary flow rates. Because of the importance of saliva in the maintenance and the preservation of oral health, management of oral diseases in diabetic patients should include a comprehensive evaluation of salivary function.

Abstract
OBJECTIVES The oral health of a large cohort of adult insulin-dependent diabetic patients (Type 1), diagnosed 24 years previously with juvenile onset, was comprehensively assessed. This paper describes the prevalence of coronal and root caries in this adult Type 1 diabetic population and evaluates demographic, dietary, behavioral, physiologic, salivary and medical variables associated with decayed and filled surfaces in the crown (DFS) or root (RDFS). METHODS Type 1 diabetes mellitus subjects participating in this oral health evaluation had been monitored for 6-8 years as participants in the University of Pittsburgh, Department of Epidemiology, longitudinal study of medical complications associated with diabetes. Four hundred and six diabetic subjects received a comprehensive oral health examination during one of their regularly scheduled medical visits. Oral assessments included coronal and root caries, missing teeth, edentulism, periodontal status, soft tissue pathologies, salivary function and health behaviors. Sixteen diabetic subjects and one control subject were edentulous. Coronal and root caries data from the remaining 390 dentate diabetic subjects were compared with 202 dentate nondiabetic control subjects. RESULTS The adult Type 1 diabetic subjects were not found to have significantly higher DFS rates as compared with our control subjects or published age-adjusted NHANES III findings. Both control and diabetic subjects had low decayed to filled tooth surface ratios. A linear regression model evaluated possible associations with coronal decayed and filled tooth surfaces (DFS) within the diabetic population. Significant factors included older age, women, fewer missing teeth, more frequent use of dental floss, more frequent visits to the dentist during the last 12 months, and diabetic nephropathy. The prevalence of RDFS was higher in the diabetic subjects as compared to recruited control subjects. Neither dietary behaviors nor glycemic control were found to contribute to coronal or root caries. CONCLUSIONS Factors associated with presence of coronal and root caries and fillings are discussed. Possible causes and implications for the association between DFS and diabetic nephropathy are provided.

Abstract
BACKGROUND Diabetes is a chronic metabolic disease known to affect oral disease progression. The authors surveyed health behaviors essential for preventing dental and periodontal diseases and maintaining oral health is a population of adult patients with type 1 (insulin-dependent) diabetes. The goals of this study were to assess these patients' oral health behaviors, access to dental care and need for improved health education. METHODS As part of a dental and periodontal examination, 406 subjects with type 1 diabetes completed a questionnaire regarding their oral health attitudes, behaviors and knowledge. The authors also evaluated 203 age-matched nondiabetic control subjects. RESULTS The authors found that diabetic subjects' tobacco use and oral hygiene behaviors were similar to those of the nondiabetic control subjects. Diabetic subjects, however, more frequently reported the cost of dental care as a reason for avoiding routine visits. Most of these subjects were unaware of the oral health complications of their disease and the need for proper preventive care. CONCLUSIONS Patients with diabetes appear to lack important knowledge about the oral health complications of their disease. The results of this survey did not indicate improved prevention behaviors among the subjects with diabetes compared with nondiabetic control subjects. CLINICAL IMPLICATIONS Dentists have an opportunity and the responsibility to promote good oral health behaviors such as regular dental examinations, proper oral hygiene and smoking cessation that may significantly affect the oral health of their diabetic patients.

Abstract
OBJECTIVE A large epidemiologic study on oral health has found that several oral soft tissue lesions were more prevalent in subjects with insulin-dependent diabetes mellitus than in control subjects without diabetes. Our objective in part I of this article is to characterize those lesions not associated with Candida. STUDY DESIGN This cross-sectional study determined the prevalence and characteristics of oral soft tissue diseases identified during a comprehensive oral evaluation of 405 adult subjects with diabetes and 268 control subjects without diabetes. RESULTS Twenty specific oral soft tissue lesions were identified. Nearly twice as many subjects with diabetes as subjects without diabetes were found to have one or more oral soft tissue lesions (44.7% vs 25.0%; P <.0001). Subjects with diabetes also had significantly higher prevalence rates for 7 lesions, 3 of which were non-candidal: fissured tongue, irritation fibroma, and traumatic ulcers. (Four lesions generally associated with Candida infection-median rhomboid glossitis, denture stomatitis, generalized atrophy of the tongue papillae, and angular cheilitis-will be described in part II of this article.) There were no differences found between the subjects with diabetes and the control subjects for lichen planus, gingival hyperplasia, or salivary gland disease. CONCLUSIONS Oral soft tissue lesions were seen more frequently in subjects with insulin-dependent diabetes than in the control subjects. Characterization of 3 non-candidal lesions suggests that they are associated with trauma, delayed healing, or both.

Abstract
OBJECTIVE To assess the prevalence of Candida albicans and oral infection with Candida in patients with insulin-dependent diabetes mellitus (IDDM). STUDY DESIGN This cross-sectional study compared the prevalence of candidiasis in 405 subjects with IDDM and 268 nondiabetic control subjects. Assessments included evidence of clinical manifestations of candidiasis and a quantitative measure of Candida pseudohyphae in a cytologic smear from the midline posterior dorsal tongue. RESULTS More subjects with IDDM than control subjects without IDDM (15.1% vs 3.0%) were found to have clinical manifestations of candidiasis, including median rhomboid glossitis, denture stomatitis, and angular cheilitis. IDDM subjects were also more likely to have any Candida pseudohyphae in their cytologic smears (23.0% vs 5.7%; P <.0001), as well as pseudohyphae counts of >10/cm(2) (7.1% vs 0.8%; P <.0001). Diabetic subjects with median rhomboid glossitis were more likely to have a longer duration of IDDM and complications of nephropathy and retinopathy. Denture stomatitis was associated with smoking, retinopathy, higher Candida counts, poor glycemic control, and longer duration of IDDM. A multivariate regression analysis found 3 factors to be significantly associated with the presence of Candida pseudohyphae in the subjects with IDDM: current use of cigarettes (odds ratio, 2:4), use of dentures (odds ratio, 2:3), and elevated levels of glycosylated hemoglobin (odds ratio, 1:9). The use of antimicrobials, immunosuppressants, or drugs with xerostomic side effects was not related to the presence of Candida. CONCLUSIONS Candida pseudohyphae and oral soft tissue manifestations of candidiasis were more prevalent in subjects with IDDM than in control subjects without diabetes. The presence of Candida pseudohyphae was significantly associated with cigarette smoking, use of dentures, and poor glycemic control.

Abstract
BACKGROUND The periodontal disease status of 320 dentate adults, diagnosed 23.7 years previously with Type 1 insulin dependent diabetes mellitus, was evaluated. These patients had been monitored at 2-year intervals as part of a large University of Pittsburgh longitudinal study assessing the medical complications associated with insulin dependent diabetes. METHODS During one of their regularly scheduled medical examinations, a group of 320 adult dentate subjects (mean age of 32.1 years) received a periodontal examination as part of a comprehensive oral health assessment. The oral health assessment collected data regarding demographics, oral health behaviors, tooth loss, coronal and root caries, salivary functions, and soft tissue pathologies. For the periodontal assessments, 3 facial sites (mesial, midcervical, distal) of the teeth in the right maxillary/left mandibular or left maxillary/right mandibular quadrants were evaluated for calculus, bleeding on probing (BOP) and loss of gingival attachment (LOA). RESULTS Attachment loss was significantly greater for older patients whereas BOP and calculus levels were relatively constant across age categories. Univariate analyses of factors possibly related to extensive periodontal disease (LOA > or =4 mm for at least 10% of sites examined) indicated an association with older age; lower income and education; past and current cigarette smoking; infrequent visits to the dentist; tooth brushing less than once per day; older age of onset; longer duration of diabetes; and the diabetic complication of neuropathy. A multivariate regression model of all possibly significant factors found current cigarette use (odds ratio [OR] = 9.73), insulin dependent diabetes onset after 8.4 years of age (OR = 3.36), and age greater than 32 years (OR = 3.00) explained the majority of the extensive periodontal disease in this group of diabetic patients. CONCLUSIONS Management and prevention of extensive periodontal disease for Type 1 diabetic patients should include strong recommendations to discontinue cigarette smoking.

Abstract
OBJECTIVE The oral health of an adult population previously diagnosed with juvenile onset insulin dependent-diabetes was comprehensively assessed. The goal of this exploratory cross-sectional evaluation was to described the characteristics related to partial tooth loss edentulism in subjects with Type 1 diabetes mellitus. METHODS An adult population of 406 Type 1 diabetes mellitus subjects, who had been monitored for 6-8 years as part of a University of Pittsburgh longitudinal study of medical complications associated with diabetes, received an oral health examination for missing teeth, edentulism, coronal and root caries, periodontal status, and oral health behaviors. RESULTS Of the 406 subjects evaluated, 204 had no missing teeth, 186 had partial tooth loss (1-27 missing teeth), and 16 were edentulous. Patients who had partial tooth loss or who were edentulous were generally older; had lower incomes and levels of education; and had higher rates of nephropathy, neuropathy, retinopathy, and peripheral vascular disease. A logistic regression model found partial tooth loss to be significantly associated with extensive periodontal disease in remaining teeth (OR = 7.35), a duration of diabetes longer than 24 years (OR = 5.32), not using dental floss (OR = 2.37), diabetic neuropathy (OR = 2.29), household income less than $20,000 (OR = 2.21), multiple coronal caries and fillings (OR = 1.98), and bleeding on probing (OR = 1.82). CONCLUSIONS Although the majority of these adult Type 1 diabetes patients had serious medical complications associated with their diabetes, the possible impact of diabetes mellitus on oral health should be included in their overall management.

Abstract
Although apparently dissimilar in both structure and function, the gut and locomotor system are linked by a number of clinical syndromes in which both are involved. In inflammatory bowel disease, intestinal mucosal inflammation is the primary problem, but may be associated with both axial and peripheral arthropathies. In the seronegative spondyloarthropathies the primary problem is in the locomotor system, but intestinal abnormalities may also be present. In addition, non-steroidal anti-inflammatory drugs used in their treatment, may cause a distinct enteropathy which may be confused with the disease-related intestinal abnormalities. The clinical, histological and genetic features of these conditions are examined in order to assess their relationship and the central role of the intestinal mucosa in their pathogenesis.

Abstract
The effect of HMG-CoA reductase inhibitors on Lp(a) concentrations is controversial, with some studies showing an increase and others showing no effect on Lp(a) concentrations. Many of these studies have been limited by small sample size and the lack of a prospective design. We evaluated the effect of four treatments: (1) placebo, (2) simvastatin 10 mg PO QPM, (3) simvastatin 20 mg PO QAM, and (4) simvastatin 20 mg PO QPM on Lp(a) concentrations in a prospective, randomized, controlled clinical trial of 24 weeks in 343 subjects in 28 clinical sites in the United States. Simvastatin was not associated with a change in Lp(a) concentrations relative to placebo. These results were not affected by controlling for race, initial Lp(a) level, or urinary albumin excretion. Simvastatin significantly reduced low-density lipoprotein (LDL) cholesterol levels (10 mg PO QPM: -27.6%; 20 mg PO QAM: -28.1%; and 20 mg PO QPM: -34.3%, all p < 0.001). It was concluded that in a large, randomized, controlled trial, simvastatin does not affect Lp(a) levels but markedly lowers LDL cholesterol levels.

Abstract
Deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE) is a major source of mortality and morbidity in stroke patients. This study was designed to determine the effectiveness of different prophylactic treatments in the prevention of DVT after a stroke in patients undergoing rehabilitation. An additional objective was the identification of risk factors for DVT in stroke in patients during rehabilitation. Three hundred and sixty patients, over a 3-year period, were randomly assigned to one of four groups: adjusted dose heparin, intermittent pneumatic compression (IPC), functional electrical stimulation (FES), or control. There was no significant difference in the development of DVT by treatment group. Patients with DVT on admission (prevalent, n = 61) were compared with the study patients (n = 360). Time interval (from stroke to admission) and lactic dehydrogenase (LDH) concentration were significant risk factors, as well as predictors, for development of DVT (p < .000). These results suggest that the longer a patient remains without DVT prophylaxis after a stroke, the greater the risk of developing DVT and this supports early prophylaxis before rehabilitation.

Abstract
BACKGROUND The management of pheochromocytoma has evolved through refinements in diagnosis, localization, and pharmacologic therapy for hemodynamic control both before and during operation. To provide a benchmark for comparison and to assess the feasibility of surgical resection using a posterior or laparoscopic approach, we reviewed the overall management and outcome of 110 patients who underwent primary resection of pheochromocytoma or paraganglioma between 1980 and January 1992 at the Mayo Clinic. METHODS Patient records were reviewed for demographic information, associated conditions, symptoms, laboratory evaluation, localizing techniques, preoperative adrenergic blockade, intraoperative hemodynamics, tumor location, pathologic conditions, and outcome. RESULTS The most prominent symptoms included headaches, sweating, and palpitations. Forty-seven percent of patients had sustained hypertension, and classic paroxysmal attacks were present in 72%. The combination of urinary metanephrines and vanillylmandelic acid had a sensitivity of 98% in detecting the disease. The positive and negative predictive values for localization of tumors by computed tomography scan were 95% and 100%, respectively. With routine alpha- and beta-blockade, there were no complications associated with intraoperative hypertension. Perioperative mortality was less than 1% and morbidity was 16%. More than 90% of patients were restored to a condition of normotension; only 20% of these required medication. CONCLUSIONS Surgical resection of these tumors, via a transabdominal approach, can be accomplished safely and hospitalization usually extends a week. Today the diagnosis, localization, preoperative blockade, intraoperative hemodynamic control, and postoperative management have reached a level sufficient to permit either a posterior or laparoscopic approach, but only if they can be mastered technically.

Abstract
Family history data were collected in 1203 consecutive admissions of insulin-dependent diabetes mellitus cases to the Children's Hospital of Pittsburgh between Dec. 31, 1964 and Jan. 1, 1981. This report deals with two issues: the closeness in time of dates of onset of diabetes in multiple sibling case families and the similarity of ages of onset within these families. The age-specific incidence rates among siblings were 6-18 times higher than in the general population. Contrary to other reports, this study does not find an increased risk to siblings during the first year or two after the onset of the index diabetic case. The mean duration between cases is 6.1 years. Fitting a log-normal distribution to the periods between cases verified the long median incubation period (4.35 years) with a high degree of variability (dispersion factor = 3.38). However, the log-normal was not a good fit to the data (p less than 0.005). There is a significant correlation for age of onset for pairs of affected siblings within families (0.25). However, it is shown that the similarity in age of onset within families may be a function of the greater similarity to ages of siblings within a family. It is noted that secondary cases are more often younger children in the family, particularly so if the index child is of school age at the time of onset.

Abstract
Rowachol, a proprietary choleretic containing 6 pure monoterpenes markedly elevates serum HDL cholesterol (SHDL-C) concentrations in man. The concentration of SHDL-C showed a progressive increase in 16 patients treated with 6-9 capsules of Rowachol daily for periods of 2-28 weeks. There was no accompanying significant change in the concentrations of serum total cholesterol or triglyceride. In view of the significant inverse relationship between SHDL-C concentration and the risk of developing ischaemic heart disease, it is suggested that Rowachol and possibly other terpenes merit further investigation as possible therapeutic agents in the prevention and treatment of atheroma.

Abstract
The immune status of 35 patients with renal failure was studied shortly after they had commenced treatment by chronic haemodialysis to see if a group with poor immunological responses could be identified. Of 27 patients who were unimmunised to start with, only two developed lymphocytoxic antibodies after a year of treatment. The routine immunological tests that were carried out on these patients failed to predict which of them would develop antibodies, and the values that were obtained for the group of cytotoxic negative patients were no different from those obtained for the two patients who became immunised and six others who had previously rejected a kidney transplant. By using a new test that measured cellular immunity to rat antigens, eight patients could be identified as "poor responders." These individuals had in addition failed to develop cytotoxic antibodies during dialysis, had serum IgG levels that were significantly lower than normal, and were uniformly unresponsive to purified protein derivative. This group of patients might be a favoruable one to transplant.
