1/301. cyclosporine disposition and long-term renal function in a 500-pound kidney transplant recipient.Patient size has been suggested as a risk factor in kidney transplantation. We have followed a recipient of a cadaver kidney who became massively obese (232 kg, 511 lbs) 5 years posttransplantation. He has maintained stable renal function with no rejection episodes and at 5 years has a measured serum creatinine of 2.2 mg/dL, creatinine clearance 42 mL/min, and urinary protein excretion of 320 mg/24h. Both oral and intravenous cyclosporine (Sandimmune) pharmacokinetic studies were done on a steady-state dose of 150 mg, which represents 0.65 mg/kg per dose. The patient exhibited very high bioavailability, F = 95%, and an oral elimination T1/2 of over 21 hours. These data confirm that stable cyclosporine delivery in very obese recipients can be sustained by dosing normalized to the ideal body weight and trough level monitoring.- - - - - - - - - - ranking = 1keywords = episode (Clic here for more details about this article) |
2/301. Acute unilateral visual loss due to a single intranasal methamphetamine abuse.An otherwise healthy 35 year old male with insulin-dependent diabetes mellitus (IDDM) presented himself three days after a single intranasal methamphetamine abusus. Directly upon awakening the day after the recreational use of this drug, he discovered an acute and severe visual loss of his right eye. This unilateral loss of vision was permanent and eventually lead to a pale and atrophic optic nerve head. The characteristics of this visual loss, together with the aspect of the optic nerve head was very similar to the classical non-arteritic ischemic optic neuropathy (NAION). We suggest a direct ischemic episode to the short posterior ciliary arteries due to this single intranasal abuse of methamphetamine as the underlying pathogenesis of this acute and permanent visual loss.- - - - - - - - - - ranking = 1keywords = episode (Clic here for more details about this article) |
3/301. Novel surgical treatment and gastric pathology in diabetic gastroparesis.AIMS: Observations are made on four Type 1 diabetic patients with the rare syndrome of intractable vomiting from confirmed gastroparesis, to determine whether radical surgery would alleviate their symptoms and subsequently to examine in detail the gastric histopathology. methods: The surgical approach consisted of an approximate 70% resection of the stomach, including the antrum and pylorus, with closure of the duodenum and restoration of gastrointestinal continuity with a 60-cm Roux-en-Y jejunal loop. Four longstanding Type 1 diabetic patients were examined and treated as described. They were all women in the age range 2741 years with grossly abnormal autonomic function tests in whom other causes for gastric paresis had been excluded. RESULTS: vomiting episodes leading to multiple hospital admissions (6-8) in the year preceding surgery were eliminated in three of the four patients, while in the fourth initial success was followed by the need for dialysis for renal failure. Gastric histopathology showed evidence of smooth muscle degeneration and fibrosis, with eosinophilic inclusion bodies (M-bodies) which appear to be unique to this condition. The findings suggest the presence of a gastromyopathy. CONCLUSIONS: Satisfactory relief of intractable vomiting from diabetic gastroparesis was achieved by a novel radical surgical procedure. Histopathological findings suggest that gastromyopathy may contribute to the production of this syndrome.- - - - - - - - - - ranking = 1.4251574255936keywords = episode, myopathy (Clic here for more details about this article) |
4/301. Evaluation of serum markers of neuronal damage following severe hypoglycaemia in adults with insulin-treated diabetes mellitus.BACKGROUND: Neurone-specific enolase (NSE) and protein s-100 (S-100) may be used as markers of acute neuronal damage in humans with neurological disorders. METHOD: To evaluate their use following a single episode of severe hypoglycaemia (defined as an episode requiring external assistance to aid recovery), serum concentrations of NSE and S-100 were measured following hypoglycaemia which had not caused persistent neurological impairment in 16 patients with insulin-treated diabetes (the 'hypo' subjects), and in three diabetic patients who died following severe hypoglycaemia. The serum proteins were also measured in 10 subjects with insulin-treated diabetes who had not experienced an episode of severe hypoglycaemia within the preceding year (the 'control' subjects). RESULTS: No differences in serum concentrations of NSE and S-100 were observed between the 'control' and the 'hypo' subjects at either 36 hours or seven days after the episode of severe hypoglycaemia (p>0.05). However, in two of the three subjects who died following hypoglycaemia, serum concentrations of the markers were markedly elevated. CONCLUSIONS: Any neuronal injury occurring during severe hypoglycaemia that is not associated with persistent neurological deficit is insufficient to provoke elevation of these serum markers. However, the measurement of serum concentrations of NSE and S-100 may have a prognostic role in evaluating clinical outcome following severe hypoglycaemia which is associated with neurological damage.- - - - - - - - - - ranking = 4keywords = episode (Clic here for more details about this article) |
5/301. Rhinocerebral mucormycosis in patients with burns: case report and review of the literature.mucormycosis is an opportunistic infection most commonly occurring in patients with impaired host defenses or diabetes mellitus. In patients with burns the rhinocerebral form is rare, and mucormycotic infections more commonly involve the cutaneous burn wound. Both forms are associated with a high mortality rate that increases with delays in treatment. The initial management of these types of infections includes vigorous glucose control, correction of acidosis, and the administration of systemic antifungal agents such as amphotericin b. The rhinocerebral form of mucormycosis is extremely virulent and may warrant the use of interstitial and intraventricular antifungal therapy. Despite these measures, the mainstay of treatment for both forms of mucormycosis is the extensive surgical debridement of all infected and necrotic tissue.- - - - - - - - - - ranking = 2.4229618695825keywords = acidosis (Clic here for more details about this article) |
6/301. Rhinocerebral mucormycosis: a case of a rare, but deadly disease.Rhinocerebral mucormycosis is a rare fungal infection of the nasal cavity and sinuses that can spread to the orbits and cranium within days. Its presentation can be confused with those of sinusitis, viral infections, diabetic ketoacidosis, or carotid sinus thrombosis, and it is often missed at early presentation. survival is directly linked to early detection and treatment. We present a case of rhinocerebral mucormycosis and discuss the literature on its early signs and symptoms, pathophysiology, and treatment options.- - - - - - - - - - ranking = 2.4229618695825keywords = acidosis (Clic here for more details about this article) |
7/301. A dentoalveolar abscess in a pediatric patient with ketoacidosis caused by occult diabetes mellitus: a case report.oral health professionals are frequently asked to evaluate patients with routine odontogenic infections. These patients can sometimes present with systemic signs and symptoms, including fever, malaise, tachycardia, and dehydration. It is important for the astute clinician to understand the possible associated systemic diseases that may be contributing to odontogenic infections. We present here an interesting case of a pediatric patient with a routine canine space infection who exhibited classic clinical signs and symptoms of diabetic ketoacidosis.- - - - - - - - - - ranking = 12.114809347913keywords = acidosis (Clic here for more details about this article) |
8/301. Painful swelling of the thigh in a diabetic patient: diabetic muscle infarction.A 44-year-old woman with a 5-year history of poorly controlled Type 1 diabetes mellitus presented with a painful, firm and warm swelling in her right thigh. pain was severe but the patient was not febrile, and had no history of trauma or abnormal exercise. Laboratory tests showed ketoacidosis, major inflammation (erythrocyte sedimentation rate (ESR) = 83 mm/h), normal white blood cell count and normal creatine kinase level. Plain radiographs were normal, and there were no signs of thrombophlebitis at Doppler ultrasound. magnetic resonance imaging (MRI) showed diffuse enlargement and an oedematous pattern of the adductors, vastus medialis, vastus intermedius and sartorius of the right thigh. The patient's symptoms improved dramatically, making biopsy unnecessary, and a diagnosis of diabetic muscular infarction was reached. Idiopathic muscular infarction is a rare and specific complication of diabetes mellitus, typically presenting as a severely painful mass in a lower limb, with high ESR. The diabetes involved is generally poorly controlled longstanding Type 1 diabetes with established microangiopathy. Differential diagnoses include deep vein thrombosis, acute exertional compartment syndrome, muscle rupture, soft tissue abscess, haematoma, sarcoma, inflammatory or calcifying myositis and pyomyositis. In fact, physician awareness should allow early diagnosis on the basis of clinical presentation, routine laboratory tests and MRI, thereby avoiding biopsy and its potential complications as well as unnecessary investigations. rest, symptomatic pain relief and adequate control of diabetes usually ensure progressive total recovery within a few weeks. Recurrences may occur in the same or contralateral limb.- - - - - - - - - - ranking = 2.4229618695825keywords = acidosis (Clic here for more details about this article) |
9/301. Preservation of vision through Weiss ring after dense vitreous hemorrhage.PURPOSE: To report an unusual case of retained vision through a Weiss ring in the setting of dense vitreous hemorrhage. METHOD: Case report of a 55-year-old woman with a 23-year history of type 1 diabetes mellitus who presented with new onset of blurred vision in the left eye as a result of a dense vitreous hemorrhage. RESULTS: The patient had received full scatter laser photocoagulation for proliferative diabetic retinopathy in the right eye several years earlier and reported previous resolving episodes of vitreous hemorrhage in the left eye. Best-corrected visual acuity in the left eye was hand motions at 3 feet. However, with careful head positioning visual acuity improved to 20/40 through a small clear central island. Examination of the left fundus showed a dense vitreous hemorrhage with a clear, mobile opening in the posterior hyaloid corresponding to the Weiss ring. The retina could be partially visualized only through the area of the Weiss ring. CONCLUSIONS: This unusual case demonstrates the anatomical relationship between the posterior hyaloid and Weiss ring.- - - - - - - - - - ranking = 1keywords = episode (Clic here for more details about this article) |
10/301. Riding out a diabetic emergency.Acute complications of diabetes are like a runaway roller coaster. Diabetes or its treatment can rocket your patient's blood glucose level to dizzying heights or plunge it to life-threatening lows. hypoglycemia, the most common endocrine emergency, typically occurs in a known diabetic patient whose therapy with insulin or oral diabetes agents goes awry. At the opposite extreme, soaring blood glucose levels mark the acute conditions diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic nonketotic state (HHNS). These complications may send the patient to the emergency department (ED) before he even knows he has diabetes. In this article, I'll explain how these problems develop and spell out nursing measures to get your patient back on track.- - - - - - - - - - ranking = 2.4229618695825keywords = acidosis (Clic here for more details about this article) |
