Abstract
OBJECTIVE Increased mortality from respiratory diseases was observed in epidemiological studies of patients with ulcerative colitis [UC] as a potentially underestimated extraintestinal manifestation. We therefore investigated the presence of pulmonary manifestations of inflammatory bowel disease [IBD] and the potential effect of tumour necrosis factor alpha [TNF-α] inhibitors on pulmonary function tests [PFT] in a prospective, longitudinal study. METHODS In all, 92 consecutive patients with IBD (49 Crohn´s disease [CD], 43 UC) and 20 healthy controls were recruited. Fifty patients with IBD were in remission, and 42 had active disease with 22 of these being examined before and 6 weeks after initiating anti-TNF therapy. Pulmonary function tests [PFT] were evaluated using the Medical Research Council [MRC] dyspnoea index and a standardized body plethysmography. IBD activity was assessed using Harvey-Bradshaw index for CD and partial Mayo score for UC. Data are presented as mean ± standard error of the mean [SEM]. RESULTS Patients with active IBD showed significant reduction of PFT. Forced expiration [Tiffeneau index] values [FEV1%] were significantly reduced in IBD patients with active disease [78.8 ± 1.1] compared with remission [86.1 ± 0.9; p = 0.0002] and with controls [87.3 ± 1.3; p = 0.001]. Treatment with anti-TNF induced a significant relief in obstruction [p = 0.003 for FEV1% in comparison with baseline levels]. The level of pulmonary obstruction significantly correlated with clinical inflammation scores [HBI or Mayo]. CONCLUSIONS: PATIENTS with active IBD present with significant obstructive abnormalities in their PFTs. Obstruction is related to inflammatory activity, with anti-TNF improving PFTs. Pulmonary obstruction and possibly chronic bronchopulmonary inflammation is an overlooked problem in active IBD that is probably obscured by intestinal symptoms.

Abstract
BACKGROUND Prior studies have provided data indicating the existence of close interaction between pancreatic endocrine and exocrine function, but few clinical studies have explored this relationship in depth. We compared pancreatic exocrine function non-endoscopically in individuals with type 1 diabetes mellitus, type 2 diabetes mellitus, and normal glucose tolerant controls, to assess the importance of local insulin production to pancreatic exocrine function. METHODS The plasma amylase response to intravenous secretin challenge was measured in men with type 1 diabetes mellitus (n = 5), type 2 diabetes mellitus (n = 5), and normal controls (n = 3). Patients were characterized by their urinary excretion of c-peptide and albumin over 24 hours. Autonomic neuropathy was non-invasively assessed by measuring RR variation (with deep respiration on EKG). RESULTS Post-secretin amylase responses were generally absent with low baseline levels in the patients with type 1 diabetes mellitus. Patients with type 2 diabetes mellitus and controls showed similar twofold increases over baseline after secretin administration. When normal glucose tolerant and type 2 diabetic patients were pooled and compared against type 1 diabetes mellitus, the differences were statistically significant (p < 0.03). Total amylase response correlated positively, but weakly, with 24 h urinary C-peptide excretion (r = 0.507; p < 0.112), but not with glycemic control, duration of diabetes, or indices of autonomic neuropathy. CONCLUSIONS Patients with type 1 diabetes mellitus, but not type 2 diabetes mellitus, have reduced pancreatic exocrine function, supporting the concept of a local paracrine effect of insulin on pancreatic acinar cells. Further studies are needed to determine the clinical impact of this deficiency, and whether such patients with type 1 diabetes mellitus would benefit from therapy with pancreatic enzyme supplementation.

Abstract
PURPOSE A prospective study to evaluate the diagnostic potential and limitations of three fast MRI sequences in patients with bronchial carcinoma based on the comparison with spiral CT. MATERIAL AND METHODS Three fast chest MRI sequences from 20 patients with central or peripheral bronchial carcinoma were evaluated by two observers for relation of tumour to adjacent structures, lymph node enlargement, additional pulmonary lesions and artefacts. The information from MR-imaging was compared with the results from spiral CT. MRI comprised a T1-3D-GRE breath-hold examination ("VIBE", TR/TE 4.5/1.9 ms, flip-angle 12 degrees , matrix 502 x 512, 2.5 mm coronal slices), a breath-hold, T2-HASTE sequence (TR/TE 2000/43 ms, matrix 192 x 256, 10 mm coronal slices) and a respiration-triggered T2-TSE sequence (TR/TE 3000-6000/120 ms, matrix 270 x 512, 6 mm transverse slices). The FOV was adapted individually (380-480 mm). RESULTS The presence of the primary bronchial carcinoma and infiltration of thoracic structures by tumour tissue could be demonstrated by all sequences. VIBE sequence was more suitable for detecting small pulmonary nodules than the other MRI examinations, but compared to CT still 20% of these lesions were missed. Contrary to VIBE and T2-weighted TSE scans, HASTE sequence was limited in imaging mediastinal lymph nodes due to missing relevant findings in 2/20 patients. HASTE images significantly provided the lowest rate of artefacts in imaging lung parenchyma (P < 0.001 in peripheral parenchyma), but spatial resolution was limited in this sequence. Concerning the differentiation between tumour and adjacent atelectasis (n = 8), T2-weighted TSE imaging was superior to CT and VIBE in all cases and to HASTE sequence in 4/8 patients. CONCLUSION The combination of VIBE and HASTE sequence allows for an adaequate imaging of thoracic processes in patients with bronchial carcinoma, limited only in visualizing small pulmonary nodules. To obtain more detail resolution and to differentiate tumour tissue from adjacent atelectasis, T2-TSE examination may be added in selected cases.

Abstract
Thirty-five insulin-treated diabetics without overt proteinuria or hypertension, and taking no antihypertensive medications were screened at three clinical centers for the presence of microalbuminuria. In addition to the presence of albuminuria, patients were evaluated for duration and type of diabetes, retinopathy, blood pressure, and degree of diabetic control. In these patients, it was possible to examine the degree of microalbuminuria as a function of systolic and diastolic blood pressures, age and sex of the patient, site of recruitment, duration of diabetes, and glycemic control. On multivariate statistical analysis, systolic blood pressure was the only factor that contributed to microalbuminuria. An additional 37 patients had urinary albumin excretion measured, although biochemical and clinical characteristics were incompletely determined. Blood pressures were documented to be normal in 23 of these individuals, while the other fourteen were normal by history. The range of urinary albumin excretion was comparable in the patients with complete data bases and those without. Overall, 22.2% of the normotensive insulin-treated patients screened had microalbuminuria, 5.5% had gross albuminuria, while 72.2% had normal urinary albumin excretion. We agree with previous reports that microalbuminuria is relatively uncommon in the normotensive diabetic population, but further conclude that even in the context of "normal" blood pressure, systolic blood pressure should be carefully observed in diabetic patients. It is possible that these individuals should be considered for more aggressive monitoring programs, e.g., ambulatory blood pressure recording.

Abstract
Abstract
We describe a patient whose serum gave consistently low results for thyroxin as measured with the Abbott TDx but normal results by radioimmunoassay. Further clinical and laboratory studies did not support the low TDx results. Anti-thyroxin antibodies did not explain the discordant results, and we found no evidence of heterophilic antibodies in the patient's serum. We were unable to identify the cause of the problem.

Abstract
Human plasma aldosterone can be rapidly, directly, and reliably measured by radioimmunoassay with use of a commercially available anti-aldosterone antibody. With this method, we show that values tend to decrease with advancing age, especially after the sixth decade.
