1/101. Aortic dissection in young patients with chronic hypertension.We describe four patients aged 14 to 21 years who developed acute aortic dissection. In three of the four patients, the course was fatal, despite aggressive medical and surgical intervention. All four patients had sustained systemic hypertension related to chronic renal insufficiency. The patients had no other identifiable risk factors for aortic dissection, including congenital cardiovascular disease, advanced atherosclerosis, vasculitis, trauma, pregnancy, or family history of aortic dissection. Although aortic dissection is rare in individuals younger than 40 years of age, young patients with sustained systemic hypertension are at increased risk for this serious and often fatal condition. physicians must be aware of this rare complication of hypertension and consider aortic dissection in the differential diagnosis of unusual chest, abdominal, and back pain in hypertensive children, adolescents, and young adults.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
2/101. Internuclear ophthalmoplegia following minor head injury: a case report.Internuclear ophthalmoplegia (INO) is a common sign of multiple sclerosis in young patients and of vascular diseases in older people. Traumatic bilateral internuclear ophthalmoplegia following severe head injuries may occur. We present the unusual case of a young patient suffered from bilateral INO as an isolated finding after a minor head injury, without other signs of brain stem or cortical injury. The ophthalmoplegia has persisted for 22 months.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
3/101. Use of topical recombinant human platelet-derived growth factor-BB (becaplermin) in healing of chronic mixed arteriovenous lower extremity diabetic ulcers.lower extremity ulcers cause significant morbidity and mortality in patients with diabetes. The primary factors that contribute to the development of this type of ulcer are peripheral neuropathy and peripheral vascular disease, which are often accompanied by infection. lower extremity diabetic ulcers are chronic and difficult to treat, in part due to underlying pathologic conditions in individuals with diabetes that can contribute to impaired wound healing. This article reports the author's experience with treatment of chronic lower extremity ulcers of mixed etiologies with recombinant human platelet-derived growth factor--BB [rhPDGF-BB, REGRANEX (becaplermin) Gel 0.01%] in a patient with multiple risk factors including long-standing insulin-dependent type 2 diabetes.- - - - - - - - - - ranking = 28.647020535097keywords = diabetic, vascular disease (Clic here for more details about this article) |
4/101. Healing of chronic leg ulcers in diabetic necrobiosis lipoidica with local granulocyte-macrophage colony stimulating factor treatment.Two young insulin-dependent diabetic patients suffering from chronic nonhealing leg ulcers of necrobiosis lipoidica diabeticorum were treated by applying topically recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) on the ulcer repetitively during 10 weeks. Evaluation of ulcer size was assessed with clinical examinations at 1-week or 2-week intervals. Topical GM-CSF healed the ulcers of both patients in 10 weeks. Decrease in the size of the ulcers was already evident after the first topical applications. During follow-up, the ulcers have remained healed for more than 3 years. This excellent treatment result suggests that topically applied GM-CSF may be a valuable drug for chronic, nonhealing ulcers in patients with diabetes.- - - - - - - - - - ranking = 33.176424642117keywords = diabetic (Clic here for more details about this article) |
5/101. The efficacy of octreotide therapy in chronic bleeding due to vascular abnormalities of the gastrointestinal tract.BACKGROUND: The treatment of angiodysplasia and watermelon stomach, vascular abnormalities implicated in gastrointestinal bleeding of obscure origin, is a major clinical problem. AIM: To determine the efficacy of octreotide in patients with long-standing gastrointestinal bleeding due to acquired angiodysplasia and watermelon stomach, resistant to previous treatments and not suitable for surgery because of old age and/or concomitant disorders. patients AND methods: We treated 17 patients (seven had isolated angiodysplasia, seven had multiple upper and lower gastrointestinal angiodysplasia, and three had watermelon stomach) with octreotide (0. 1 mg subcutaneous t.d.s. for 6 months). Six of the patients had liver cirrhosis, one had Glanzmann-type platelet derangement, two had cardiovascular diseases and one had chronic uraemia. RESULTS: octreotide treatment stopped bleeding in 10 patients. A transient improvement was observed in four, who needed subsequent cyclical retreatment to correct low haemoglobin levels. No effect was observed in three, probably due to the severity of the concomitant disorders. CONCLUSIONS: octreotide is a safe drug that may be useful to control the recurrent gastrointestinal bleeding due to acquired angiodysplasia and watermelon stomach, especially in patients who are not candidates for surgery due to old age and/or concomitant disorders.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
6/101. Reversal of hypoglycemia unawareness in a long-term type 1 diabetic patient by improvement of beta-adrenergic sensitivity after prevention of hypoglycemia.The purpose of this study was to assess the effect of strict avoidance of hypoglycemia on beta-adrenergic sensitivity in a type 1 diabetic patient with hypoglycemia unawareness and a diabetes duration of 55 yr. beta-Adrenergic sensitivity was determined by an isoproterenol test and was expressed as the lowest dose of isoproterenol that increases the heart rate by 25 beats/min (IC25). plasma epinephrine and symptom responses to hypoglycemia were determined during a 3-h hypoglycemic (3 mmol/L) clamp. Initially, the patient had a near-normal counterregulatory plasma epinephrine response to hypoglycemia but reduced beta-adrenergic sensitivity (IC25, 2 microg) compared to 10 hypoglycemia aware, type 1 diabetic patients (0.65 /- 0.14 microg) and 10 normal control subjects (1.13 /- 0.21 microg). After 1 yr of strict avoidance of blood glucose levels below 4 mmol/L, the IC25 decreased to 0.25 microg, reflecting improved beta-adrenergic sensitivity. In conclusion, the reduced beta-adrenergic sensitivity in this patient was probably the reason for hypoglycemia unawareness and was reversed by strict avoidance of hypoglycemia.- - - - - - - - - - ranking = 33.176424642117keywords = diabetic (Clic here for more details about this article) |
7/101. Filleted toe flap for chronic forefoot ulcer reconstruction.Chronic plantar and dorsal forefoot ulcer may result from injury, structural deformity, and abnormal sensation or circulation. It is not uncommon that the distal portion of the affected toes is deficient functionally in these patients. A filleted toe flap from the expendable functionless toe can provide a durable, stable, and sensate skin flap of 4 to 5.5 cm for coverage of the forefoot defect. In this report, five cases of dorsal forefoot defects and four cases of plantar forefoot defects due to ischemia (N = 3), trophic change (N = 2), and diabetes (N = 4) were treated with filleted toe flaps. One flap failed due to postoperative deep infection. The other eight filleted toe flaps survived but 2 patients underwent secondary amputations 7 months and 2 two years later because of secondary diabetic foot infections.- - - - - - - - - - ranking = 5.5294041070194keywords = diabetic (Clic here for more details about this article) |
8/101. Identification of bacteria from a non-healing diabetic foot wound by 16 S rDNA sequencing.Approximately 10-20% of diabetic foot wounds fail initial antibiotic treatment. It is generally believed that several bacterial species may be present in these types of wounds. Because some of these organisms cannot be easily cultured, proper identification is problematic and thus, appropriate treatment modalities cannot be applied. This report examined the bacterial flora present in a chronic diabetic foot wound that failed antibiotic treatment. A tissue sample was collected from the base of the wound and used for standard microbiological culturing. dna from the sample was used to amplify bacterial 16 S rDNA gene sequences and a library of these sequences was made. The clones were placed into two major groups on the basis of their melting temperatures. Representatives of these groups were sequenced, and information was used to identify the bacteria present in the wound. The culture-based method identified a single anaerobic species, bacteroides fragilis. The method employing rDNA sequencing identified B. fragilis as a dominant organism and pseudomonas (Janthinobacterium) mephitica as a minor component. The results indicate that rDNA sequencing approach can be an important tool in the identification of bacteria from wounds.- - - - - - - - - - ranking = 33.176424642117keywords = diabetic (Clic here for more details about this article) |
9/101. Sudden cortical hearing loss for speech: a case report.A 35-yr-old male patient experienced a sudden loss of speech understanding due to a bilateral cerebrovascular disease. A detailed summary of audiological and neurological findings was presented. Findings indicated that the presence of Pa waves of the Middle Latency Response (MLR) may be a positive prognosis for improvement in hearing thresholds and speech understanding.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
