1/1224. Latent coeliac disease. Personal experience.Latent coeliac disease (L.C.D.) is an extremely rare condition to describe. In this study we analyzed three cases of patients affected by L.C.D.: two of them suffered from insulin-dependent diabetes mellitus (IDDM) and the other one from infantile cerebral palsy and eosinophilic gastroenteritis. We confirm the existence of this form of coeliac disease (C.D.), by means of duodenal biopsy, and stress the importance of an early diagnosis in order to prevent the serious consequences caused by untreated C.D.- - - - - - - - - - ranking = 1keywords = diabetes (Clic here for more details about this article) |
2/1224. insulin dependent diabetes mellitus (IDDM) and autoimmune thyroiditis in a boy with a ring chromosome 18: additional evidence of autoimmunity or IDDM gene(s) on chromosome 18.A 4 year 3 month old boy with insulin dependent diabetes mellitus (IDDM), autoimmune thyroiditis, slight mental retardation, facial dysmorphism, and a de novo ring chromosome 18 (deletion 18q22.3-18qter) is described. This unique association of defects could represent a chance association. Alternatively, the clinical features could be the result of the chromosomal aberration. If so, one could speculate that a gene or genes on chromosome 18 might act as a suppressor or activator of the autoimmune process by itself or in concert with other IDDM loci.- - - - - - - - - - ranking = 5keywords = diabetes (Clic here for more details about this article) |
3/1224. travel-related morbidity in travelers with insulin-dependent diabetes mellitus.BACKGROUND: To assess whether there are clinically significant problems in patients with insulin-dependent diabetes mellitus (IDDM) traveling to tropical countries regarding metabolic dysregulations, infectious complications and general health problems. methods: A retrospective, descriptive cohort study by telephone interview of all IDDM patients who had received pretravel health advice at our travel clinic during a 12 month period. Data were collected on IDDM related problems: hypo-/hyperglycemic dysregulation, infectious complications, practical difficulties, exploring risk factors, as well as on general health problems. RESULTS: Of the 19 respondents, 13 (68%) reported any metabolic dysregulation, including all but one respondents with Type 1 diabetes. Fifty-five percent of Type 1 diabetics reported to have dysregulated more often than in the preceding period at home. Critical dysregulations occurred in 2 of the 19 study patients. Only 4 out of 11 (36%) type 1 IDDM patients increased frequency of blood glucose monitoring while traveling. Three travelers reported a febrile illness which resulted in hyperglycemic dysregulation. Five study patients experienced difficulties in the adjustment of their insulin dosage to the unfamiliar circumstances of traveling in the tropics. CONCLUSIONS: Metabolic dysregulation was a clinically significant problem, thus IDDM travelers to tropical destinations probably run extra health risks. fever, easily acquired in the tropics, appeared to be an additional, serious health problem for this study population. As the number of diabetic travelers will increase, more research on the importance of risk factors possibly leading to dysregulation is necessary.- - - - - - - - - - ranking = 6keywords = diabetes (Clic here for more details about this article) |
4/1224. Use of computed tomography and plantar pressure measurement for management of neuropathic ulcers in patients with diabetes.BACKGROUND AND PURPOSE: Total contact casting is effective at healing neuropathic ulcers, but patients have a high rate (30%-57%) of ulcer recurrence when they resume walking without the cast. The purposes of this case report are to describe how data from plantar pressure measurement and spiral x-ray computed tomography (SXCT) were used to help manage a patient with recurrent plantar ulcers and to discuss potential future benefits of this technology. CASE DESCRIPTION: The patient was a 62-year-old man with type 1 diabetes mellitus (DM) of 34 years' duration, peripheral neuropathy, and a recurrent plantar ulcer. Although total contact casting or relieving weight bearing with crutches apparently allowed the ulcer to heal, the ulcer recurred 3 times in an 18-month period. Spiral x-ray computed tomography and simultaneous pressure measurement were conducted to better understand the mechanism of his ulceration. OUTCOMES: The patient had a severe bony deformity that coincided with the location of highest plantar pressures (886 kPa). The results of the SXCT and pressure measurement convinced the patient to wear his prescribed footwear always, even when getting up in the middle of the night. The ulcer healed in 6 weeks, and the patient resumed his work, which required standing and walking for 8 to 10 hours a day. DISCUSSION: Following intervention, the patient's recurrent ulcer healed and remained healed for several months. Future benefits of these methods may include the ability to define how structural changes of the foot relate to increased plantar pressures and to help design and fabricate optimal orthoses.- - - - - - - - - - ranking = 5keywords = diabetes (Clic here for more details about this article) |
5/1224. Thrombotic risk in thalassemic patients.Hemostatic parameters of 495 beta-thalassemic patients (421 with thalassemia major and 74 with thalassemia intermedia) were analyzed, to assess their association with the described thrombophilic condition and to verify the role of additional risk factors (e.g. persistent postsplenectomy thrombocytosis, insulin dependent diabetes mellitus, estrogen-progestin treatment and atrial fibrillation). The prevalence of thromboembolic accidents was 5.2% and in four patients (15.3%) inherited or acquired predisposing defects were recognized. The incidence of thromboembolic events and the associated relative risk due to hemocoagulative abnormalities in these patients are discussed.- - - - - - - - - - ranking = 1keywords = diabetes (Clic here for more details about this article) |
6/1224. T-cell insulitis found in anti-GAD65 diabetes with residual beta-cell function. A case report.CASE history: We recently encountered a 65-year-old anti-GAD diabetic woman with residual beta-cell function who was proved to have T-cell insulitis. The proportion of CD4 and CD8 cells varied among individual islets, although CD4 cells tended to be the predominant T-cell type in the islets examined. All of the islets examined still contained insulin, suggesting that beta-cell mass may have been preserved. DISCUSSION: It is well known that lymphocytic infiltration of pancreatic islets, a condition referred to as "insulitis," is seen in acute-onset type 1 diabetes at autopsy and in biopsy specimens. However, there have been no proven cases of insulitis in type 1 diabetes with residual beta-cell function. We believe that this is the first type 1 diabetic patient with residual beta-cell function who was proven to have T-cell insulitis. This novel evidence will contribute to the proper classification and treatment of diabetes and to a better understanding of the pathophysiology of type 1 diabetes.- - - - - - - - - - ranking = 8keywords = diabetes (Clic here for more details about this article) |
7/1224. vitrectomy for cystoid macular oedema with attached posterior hyaloid membrane in patients with diabetes.AIM: To report the success of vitrectomy in eliminating cystoid macular oedema and improving vision in three eyes of two patients with diabetic cystoid macular oedema. In all of the eyes there was no ophthalmoscopic evidence of traction from a posterior hyaloid membrane or from proliferative tissue. methods: Pars plana vitrectomy was performed on three eyes of two patients with diabetic cystoid macular oedema who did not show traction upon examination with a slit lamp biomicroscope and a scanning laser ophthalmoscope. RESULTS: Cystoid changes disappeared 1, 3, and 5 days, postoperatively, and diffuse macular oedema resolved within 2 weeks. The visual acuity was improved and maintained. CONCLUSION: vitrectomy can be effective in some patients with diabetic cystoid macular oedema even in patients who lack evidence of traction by ophthalmoscopy.- - - - - - - - - - ranking = 4keywords = diabetes (Clic here for more details about this article) |
8/1224. Spontaneous tibial compartment syndrome in Type 1 diabetes mellitus.We present a case of a patient with Type 1 diabetes mellitus (DM) who spontaneously developed severe bilateral anterior tibial compartment syndromes which required extensive surgical treatment. While infarction of skeletal muscle in Type 1 DM remains rare and usually affects the larger compartments of the thigh, this diagnosis must be entertained in any patient presenting with acute leg pain. If a patient displays any features of acute compartment syndrome, prompt fasciotomy must be undertaken.- - - - - - - - - - ranking = 5keywords = diabetes (Clic here for more details about this article) |
9/1224. Successful obstetric outcome after simultaneous pancreas and kidney transplantation.A 34-year-old woman became pregnant two years after having a simultaneous pancreas and kidney (SPK) transplantation, necessitated by type 1 diabetes and end-stage renal disease. The pregnancy was uneventful until 30 weeks' gestation, when she developed pancreatitis and a worsening of mild hypertension. A healthy 1700 g boy was delivered by caesarean section at 34 weeks' gestation. This is the first report of a successful pregnancy after SPK transplantation in australia.- - - - - - - - - - ranking = 1keywords = diabetes (Clic here for more details about this article) |
10/1224. Three new mutations in the hepatocyte nuclear factor-1alpha gene in Japanese subjects with diabetes mellitus: clinical features and functional characterization.AIMS/HYPOTHESIS: Mutations in the hepatocyte nuclear factor-1alpha gene are a common cause of the type 3 form of maturity-onset diabetes of the young. We examined the clinical features and molecular basis of hepatocyte nuclear factor-1alpha (HNF-1alpha) diabetes. methods: Thirty-seven Japanese subjects with early onset Type II (non-insulin-dependent) diabetes mellitus and 45 with Type I (insulin-dependent) diabetes mellitus were screened for mutations in this gene. Functional properties of mutant HNF-1alpha were also investigated. RESULTS: Three new mutations [G415R, R272C and A site of the promoter ( 102G-to-C)] were found. insulin secretion was impaired in the three subjects. insulin and glucagon secretory responses to arginine in the subject with the R272C mutation were also diminished. Molecular biological studies indicated that the G415R mutation generated a protein with about 50% of the activity of wild-type HNF-1alpha. The R272C mutation had no transactivating or dna binding activity and acted in a dominant negative manner. The 102 G-to-C mutation in the A site of the promoter activity was associated with an increase in promoter activity and it had 42-75% more activity than the wild-type sequence. CONCLUSION/INTERPRETATION: Mutations in the HNF-1alpha gene may affect the normal islet function by different molecular mechanisms.- - - - - - - - - - ranking = 8keywords = diabetes (Clic here for more details about this article) |
