1/19. pregnancy outcome in aboriginal women with NIDDM in the Sioux Lookout Zone.PURPOSE: To review the pregnancy outcomes of Aboriginal women with non-insulin-dependent diabetes mellitus (NIDDM) in the Sioux Lookout Zone of Northwestern ontario, canada. METHOD: Retrospective chart review of deliveries of all women with a confirmed diagnosis of NIDDM was carried out between 1989 and 1992. RESULTS: During this period, 26 infants were born to 19 women with the diagnosis of NIDDM. Mean birth weight was 4,075 grams, with an average gestational age at delivery of 38 weeks. Three newborns required cesarean delivery, one required forceps, and one a vacuum extraction. There were four cases of shoulder dystocia. There were one stillbirth, one maternal death, and two cases of congenital heart disease. Ten newborns had neonatal jaundice and only two had neonatal hypoglycemia. These results suggest there is significant risk associated with NIDDM in pregnancy.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/19. Hb Ube-2 in a diabetic case with an abnormally low HbA1C value.A 69-year-old male diabetic patient had an abnormally low HbA1C value of 2.8%, which was inconsistent with his elevated fasting plasma glucose of 8.2 mmol/l. Hb analysis disclosed that the abnormal Hb was Hb Ube-2 [alpha68 (E17) Asn --> Asp] and it accounted for 21.5% of the total Hb. Since the glycated abnormal Hb emerged at the same position as did HbF on high performance liquid chromatography, the HbA1C value was falsely low. The present case demonstrates that Hb Ube-2 is one of the abnormal Hbs in which caution should be exercised when monitoring diabetic control.- - - - - - - - - - ranking = 298.75073636957keywords = chromatography (Clic here for more details about this article) |
3/19. A novel mutation in the hepatocyte nuclear factor-1alpha/MODY3 gene in Chinese subjects with early-onset Type 2 diabetes mellitus in taiwan.AIMS: The goal of this study was to determine the frequency of mutation in hepatic nuclear factor (HNF)-1alpha, a gene recently implicated as causing maturity-onset diabetes of the young (MODY) and to analyse the respective clinical presentations in an ethnically Chinese population. methods: Fifteen unrelated subjects (nine females and six males) aged less than 35 years who had early-onset diabetes were analysed to test the possibility that mutation of the HNF-1alpha gene was responsible for this disorder. Genomic dna extraction, polymerase chain reaction and dna sequence analysis were performed accordingly. RESULTS: One patient with MODY had a novel missense mutation in exon 3 of the HNF-1alpha gene (Y218C) in a region of the protein that corresponds to a predicted dna binding domain. CONCLUSIONS: A Y218C mutation in HNF-1alpha gene was identified in one family in taiwan.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/19. Vitreous cytology in asteroid hyalosis and observations on interpretation of cytologic findings in specimens of the posterior (vitreous) compartment of the eye.Cytologic methods have been used in the pathologic investigation of the posterior (vitreous) compartment of the eye in specimens obtained by fine-needle aspiration, as well as by surgical procedures. The vitreous body, which is in a semiliquid gel state, lends itself to pathologic investigation by cytologic methods. We report on a case of reparative eye surgery for complications of previous cataract extraction; vitrectomy was performed for vitreous opacities, which, by cytologic examination, were diagnostic of asteroid hyalosis, a relatively uncommon condition affecting the elderly. The cytologic findings diagnostic of this disease are described. Observations are made on the cytologic findings commonly encountered in specimens obtained from the posterior (vitreous) compartment of the eye.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/19. Hb Q-india: an uncommon variant diagnosed in three Punjabi patients with diabetes is identified by a novel dna analysis test.AIMS: An abnormality in the glycated haemoglobin peak (Hb A1c) on Diastat (Bio-Rad) cation exchange low pressure liquid chromatography (LPLC) was found in three Punjabi patients with diabetes. The aims of this study were to identify the variant by chromatography and electrophoresis and to determine whether a dna analysis test could be designed for confirmation that could be generally applied for the identification of any unusual abnormal haemoglobin. methods: The presence of an Hb variant was confirmed by cellulose acetate electrophoresis at pH 8.6. The variant was characterised further by high performance liquid chromatography (HPLC; Bio-Rad Variant) and isolelectric focusing (IEF) electrophoresis. A novel dna analysis test based on the amplification refractory mutation system (ARMS) and the polymerase chain reaction (PCR) was developed to confirm the presence of the mutation for the uncommon variant. RESULTS: Comparison of the HPLC retention time and IEF band position determined the presence of the variant Hb Q-india in all three cases. Hb Q-india is caused by the mutation GAC --> CAC at codon 64 of the alpha-1 globin gene and is clinically silent. ARMS-PCR specific primers were designed and used successfully to confirm the presence of the mutation for Hb Q-india. CONCLUSIONS: The results show that the ARMS-PCR technique, developed previously for the diagnosis of beta thalassaemia mutations, can also be adapted to provide a simple, rapid, and inexpensive approach for the identification of abnormal haemoglobins.- - - - - - - - - - ranking = 896.2522091087keywords = chromatography (Clic here for more details about this article) |
6/19. Artifactually low glycated haemoglobin in a patient with severe hypertriglyceridaemia.This report describes a case of artifactually low glycated haemoglobin (Hb) in a patient with type II diabetes and severe hypertriglyceridaemia. The effect of hypertriglyceridaemia on glycated Hb determination using the Abbott Vision method was investigated in a series of patients with diabetes. The interference of triglycerides in glycated Hb assays was also investigated by two other methods, the Beckman Synchron CX4 delta immunoturbidimetric method, and the Primus affinity chromatography high performance liquid chromatography assay.- - - - - - - - - - ranking = 597.50147273914keywords = chromatography (Clic here for more details about this article) |
7/19. Haemoglobin Etobicoke, an incidental finding in an Irish diabetic.It is well recognized that haemoglobin variants can be detected during the measurement of HbA1c by high-performance liquid chromatography (HPLC). A number of variants have been reported as compromising the quantification of HbA1c, a marker used in the assessment of glycaemic control in diabetes. We describe a case of haemoglobin Etobicoke, a rare alpha chain variant detected in an Irish diabetic during HbA1c analysis. Its identity was confirmed using a series of investigations. These included haemoglobin electrophoresis at alkaline and acid pH, isoelectric focusing and globin chain electrophoresis. Ultimately mass spectrometry isolated the mutation at position alpha 84 (F5). Haemoglobin Etobicoke, first described in canada in 1969 has not previously been detected on HbA1c analysis. In the presence of this rare variant, HbA1c, a standard method using HPLC to assess glycaemic control in diabetes is unreliable and alternatives such as fructosamine need to be considered. HbA1c measured by automated HPLC will effectively screen populations where haemoglobin variants were not previously known. Precise identity of these variants when they are detected is crucial to the reliable interpretation of HbA1c analyses.- - - - - - - - - - ranking = 298.75073636957keywords = chromatography (Clic here for more details about this article) |
8/19. Sudden bilateral visual loss in a diabetic man.This is a report of a case of the development of acute bilateral cataracts in a diabetic patient. A 28-year-old man presented to the emergency room with a 4-day history of acutely diminished vision. The patient had a recent history of hyperglycemia. On examination, vision was noted to be count-fingers bilaterally; both lenses were intumescent with dense cortical opacities. After 4 weeks, the cataracts had not resolved and cataract extraction surgery was performed, with improvement of the patient's vision. A review of the mechanism of this infrequent presentation of cataract is presented.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/19. felodipine-influenced gingival enlargement in an uncontrolled type 2 diabetic patient.BACKGROUND: The potential of calcium channel blockers (CCBs) to induce gingival enlargement (GE) as well as the influence of diabetes mellitus on periodontal tissues has been well documented. This case report documents a conservative clinical approach to the management of felodipine-influenced gingival enlargement and displays a clinical and histologic case of felodipine-influenced GE in an undiagnosed type 2 diabetic patient. methods: At the initial examination, a medical consultation was requested and two incisional biopsies were taken for pathological evaluation. The patient was diagnosed with uncontrolled type 2 diabetes. felodipine was withdrawn and the diabetes was controlled before dental treatment was initiated. The patient then underwent selective extractions and full-mouth scaling and root planing as well as oral hygiene instructions. No surgical therapy was indicated. RESULTS: The histological results demonstrated the presence of elongated rete pegs; fibrous hyperplasia; a low-grade chronic inflammatory infiltrate, predominantly consisting of lymphocytes; and collagen bundle groups randomly distributed. These features were similar to those present in other drug-influenced GE. Clinical results have demonstrated almost complete resolution of GE after the withdrawal of felodipine and the control of diabetes. Further improvements were seen after scaling and root planing and oral hygiene instructions. No recurrences were noted 12 months after initial therapy. CONCLUSIONS: This report demonstrated that the control of systemic factors seemed to have the most influence on success for this particular case. Since the control of diabetes was managed at the same time as the felodipine withdrawal, it remains difficult to speculate how these two factors impacted both the severity of the GE and the therapeutic results. More importantly, the conservative treatment rendered demonstrated the stability of periodontal status during maintenance phase and the avoidance of surgical interventions.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/19. association of osteonecrosis of the jaws and bisphosphonate pharmacotherapy: dental implications.Bisphosphonates are drugs of choice in the management of a variety of bone disorders including osteoporosis, Paget's disease and bone cancer. Recently there have been increasing reports of a possible relationship between bisphosphonate therapy and osteonecrosis of the jaws. osteonecrosis may occur following extractions or dental surgery and, in some cases, may appear spontaneously. Because of the potentially serious nature of these complications and the failure of exposed bone to heal, dentists must be aware of recommended precautions for the management of patients taking bisphosphonate medication.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
