Herein, we report on a paediatric patient with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) who was hospitalized for acute on chronic renal insufficiency, seizures and deterioration of the level of consciousness. She also had hypertension, hypothyroidism and nephrotic range proteinuria. Kidney biopsy revealed many sclerotic glomeruli and focal segmental glomerulosclerosis (FSGS). Glomerulopathy is rare in patients with MELAS, and FSGS has been reported only in a few patients. The histopathological features of the renal biopsy suggested that the aetiology of the FSGS may have been secondary to chronic renal injury rather than from a primary immunologic cause. Moreover, our case is unique in that, the coexistence of MELAS, hypothalamic hypothyroidism and FSGS has not been reported in the past. The purpose of this report is to increase the awareness of health-care professionals, especially in the fields of paediatrics, neurology, endocrinology and nephrology, regarding the manifestations and complications of MELAS.

Over 27 cases of liver transplant, kidney transplant and combined liver-kidney transplant have been reported for the treatment of methylmalonic aciduria. We describe a case of a 5-year-old boy who underwent combined liver-kidney transplant (CLKT) for phenotypic mut0 disease. His history was notable for more than 30 hospitalizations for severe acidosis, metabolic strokes, liver disease, pancreatic disease, chronic renal insufficiency with interstitial nephritis, and decreased quality of life. Post-CLKT, there was a marked reduction in serum (80%) and urine MMA levels (90%) as well as a cessation of metabolic decompensations. Neurologic deterioration continued post-CKLT manifested as a cerebellar stroke. The clinical details and therapeutic implications of solid organ transplant for methylmalonic aciduria are discussed.

Hypertension in a nursing home patient is a systolic blood pressure of 140 mm Hg or higher and 130 mm Hg or higher in a patient with diabetes mellitus or chronic renal insufficiency, or a diastolic blood pressure of 90 mm Hg or higher and 80 mm Hg or higher in a patient with diabetes mellitus or chronic renal insufficiency. Numerous prospective, double-blind, randomized, placebo-controlled studies have demonstrated that antihypertensive drug therapy reduces the development of new coronary events, stroke, and congestive heart failure in older persons. The goal of treatment of hypertension in elderly persons is to lower the blood pressure to less than 140/90 mm Hg and to less than 130/80 mm Hg in older persons with diabetes mellitus or chronic renal insufficiency. Elderly persons with diastolic hypertension should have their diastolic blood pressure reduced to 80 to 85 mm Hg. Diuretics should be used as initial drugs in the treatment of older persons with hypertension and no associated medical conditions. The selection of antihypertensive drug therapy in persons with associated medical conditions depends on their associated medical conditions. If the blood pressure is more than 20/10 mm Hg above the goal blood pressure, drug therapy should be initiated with 2 antihypertensive drugs, one of which should be a thiazide-type diuretic. Other coronary risk factors must be treated in patients with hypertension.

Most hospitals have reduced medical staff on weekends. Furthermore, a recent study on acute myocardial infarction suggested that weekend admissions were associated with higher mortality compared with weekday admissions. We sought to determine if compliance with guideline recommendations for acute coronary syndrome performance measures would be worse on weekends/holidays compared with weekdays. We utilized the American Heart Association's Get with the Guidelines (GWTG)--Coronary Artery Disease database. This study included 154,910 patients admitted to 515 various hospitals from January 14, 2000 to April 30, 2007 with acute coronary syndrome (ACS). Patients discharged on weekdays were older and were more likely to be women, have a history of atrial fibrillation, cerebral vascular accident/transient ischemic attack and chronic renal insufficiency, and present with unstable angina. Although patients discharged on the weekends/holidays were slightly less likely to receive angiotensin-converting enzyme inhibitors than those discharged on weekdays (68.3% vs 69.5%, p <0.0001), all other measures were similar, and a composite performance measure for 100% compliance was equal in both groups (81.5% vs 81.4%, p = 0.77). In conclusion, within GWTG participating hospitals, weekend/holiday staffing provides the same quality of care in ACS for discharge medications and counseling compared with full weekday staffing. However, there remain further opportunities to improve utilization of guideline-recommended therapies irrespective of discharge day.

Numerous double-blind, randomized, placebo-controlled studies have shown that antihypertensive drug therapy reduces cardiovascular events in elderly persons. In the Hypertension in the Very Elderly Trial, patients aged 80 years and older treated with antihypertensive drug therapy had, at 1.8-year follow-up, a 30 percent reduction in fatal or nonfatal stroke, a 39 percent reduction in fatal stroke, a 21 percent reduction in all-cause mortality, a 23 percent reduction in death from cardiovascular causes, and a 64 percent reduction in heart failure. The goal of treatment of hypertension in elderly persons is to lower the blood pressure to less than 140/90 mmHg and to less than 130/80 mmHg in older persons with diabetes or chronic renal insufficiency. All antihypertensive drugs may predispose the elderly person to develop symptomatic orthostatic hypotension and postprandial hypotension and syncope or falls. Adverse effects depend upon the antihypertensive drugs used, the doses of these drugs, the comorbidities in the elderly patients taking these drugs, and drug-drug interactions.

Our purpose was to identify preoperative and intraoperative predictors of early mortality, spinal cord injury, or acute intestinal ischemia after repair of type IV thoracoabdominal aneurysm (TAA IV) as a basis for optimizing surgical indications and techniques. From January 1991 to June 2006 we operated on 171 patients for TAA IV. There were 149 men (87.1%) and 22 women (12.9%), with a mean age of 65.0 +/- 10.9 years (range 23-82). The underlying etiology was degenerative aneurysmal disease in 143 patients (83.6%). Twenty-two patients (12.8%) underwent emergent operation. Comorbidity included coronary disease in 72 patients (45.6%) including 39 who had undergone a revascularization procedure, arterial hypertension in 121 (70.1%), chronic obstructive pulmonary disease in 81 (47.4%), and chronic kidney insufficiency in 58 (33.9%). Seventy-six patients (44.4%) presented concurrent lesions involving at least one visceral artery. Spinal cord arteriography was performed in 91 patients (53.2%). In 25 cases (27.5%) arteriographic findings demonstrated the need for revascularization of the Adamkiewicz artery due to location of the ostium at or below the T12 level. Repair was carried out with cross-clamping only in 160 cases (93.6%). Partial cardiopulmonary bypass was used in 11 patients (6.4%). A total of 23 patients (13.4%) died postoperatively. The cause of death was acute intestinal ischemia in nine cases, multiple organ failure in seven, coagulation disorder in three, cardiac complications in two, and stroke in two. Spinal cord injury occurred in eight patients (4.7%) including two who died. According to univariate analysis, the significant predictors of early death were age over 70 years, degenerative aneurysmal disease, coronary artery disease, chronic renal insufficiency or visceral artery lesions, operator, duration of intestinal ischemia and use of a "complex" surgical technique. Although the only significant predictor of spinal cord injury was duration of digestive ischemia, an almost significant trend (p < 0.1) was observed for coronary artery disease, coronary bypass, and renal insufficiency. The significant predictors of acute intestinal ischemia were kidney insufficiency and visceral artery lesions, but coronary artery disease and previous coronary bypass were almost significant (p = 0.06). Frequent association of TAA IV with arteriosclerotic disease in elderly patients presenting coronary artery disease and chronic kidney insufficiency partly explains why early postoperative mortality remains high. The incidence of spinal cord injury suggests that preoperative spinal cord arteriography is mandatory for prevention. The frequency of intestinal ischemia is more problematic, but a better understanding of the underlying mechanism should enable development of preventive strategies.

There is considerable debate regarding whether anemia qualifies as a prognostic factor for stroke. The purpose of this study was twofold: first, to assess the influence of anemia on vascular risk factors and clinical presentations in patients with first-ever atherosclerosis-related ischemic stroke and, second, to evaluate whether anemia may be of prognostic importance. A total of 774 consecutive patients with first-ever atherosclerosis-related ischemic stroke were prospectively investigated. Vascular risk factors, clinical presentations and outcomes were recorded and compared between those patients with and without anemia. Stroke recurrence and mortality were recorded at the 3-year follow-up. Of the study population, 168 (21.7%) were anemic. Multivariate analysis revealed that patients with anemia were more likely to be older than 70 years (p<0.001) and have chronic renal insufficiency (p<0.001). After a mean follow-up period of 958 days, 21 (12.5%) and 24 (4.0%) of the patients in the anemic and control groups, respectively, died. Within 3 years of initial onset, the mortality rate was significantly higher in patients with anemia (p=0.021). The Kaplan-Meier analysis for patients with and without anemia showed different survival curves (Log-rank test p<0.001). Within 3 years of the onset of first-ever atherosclerosis-related ischemic stroke, patients who had anemia at the time of the initial admission had an associated higher mortality rate. The stroke risk factors of being older than 70 years and having chronic renal insufficiency were more frequently observed in those patients with anemia.

In a retrospective study, acute renal failure (ARF) was found in 10 (3.3%) among 304 hospitalized adults with dengue hemorrhagic fever (DHF), and 6 (60%) of the 10 patients with ARF died, whereas all 294 patients without ARF (controls) survived (P < 0.001). Compared with the controls, DHF patients with ARF were found to be significantly older (P = 0.002) and male predominant (P < 0.001) and to have higher frequency of previous stroke (P = 0.005), chronic renal insufficiency (P = 0.046), dengue shock syndrome (DSS; P < 0.001), gastrointestinal bleeding (P < 0.001), and concurrent bacteremia (P = 0.009), lower hemoglobin (P = 0.003) and serum albumin levels (P = 0.003), and higher incidences of prolonged prothrombin time (P < 0.001), elevated aspartate aminotransferase (P < 0.001), and alanine aminotransferase levels (P < 0.001). Multivariate analysis showed DSS (odd ratio = 220.0; P < 0.001) was an independent risk factor for development of ARF in DHF patients. The high fatality rate in DHF patients complicated with ARF in our series underscore the importance of clinicians' alertness to this potentially fatal complication so that initiation of timely appropriate treatment is possible.

Ochrobactrum anthropi is a non-glucose fermentative, aerobic gram-negative bacillus, formerly known as Achromobacter sp or CDC group Vd. It has been isolated from the environment and from infections in usually immunocompromised human beings. The documented infections frequently involved catheter related bacteremia whereas endophthalmitis, urinary infections, meningitis, endocarditis, hepatic abscess, osteochondritis, pelvic abscess and pancreatic abscess were rarely involved. Here it is presented the case of a male patient aged 69 years with sustained hypotension, four day febrile syndrome, chill, lavish perspiration and sensorium deterioration. He had type 2 diabetes and antecedent of cerebrovascular accident. A double-lumen dialysis catheter was present due to chronic renal insufficiency. An episode of catheter-related bloodstream infection was documented by using Bact-Alert Blood Culture System and Differential-Time-to-Positivity Method for central venous catheter versus peripheral blood cultures (>120 min). Once removed, it was confirmed through Maki semi quantitative technique (>15 FCU). The microorganism was identified by API 20NE and Vitek 1 as Ochrobactrum anthropi.

Angiotensin-converting enzyme (ACE) inhibitors are a relatively homogenous drug class widely used today. They have been shown to reduce morbidity or mortality in congestive heart failure, myocardial infarction, chronic renal insufficiency, diabetes mellitus, and atherosclerotic cardiovascular disease. Pathologies underlying these conditions are partially attributable to the renin-angiotensin-aldosterone system. Angiotensin II contributes to endothelial dysfunction, altered renal hemodynamics, and vascular and cardiac hypertrophy. ACE inhibitors attenuate these effects. Clinical outcomes of ACE inhibition include lower incidence of fatal and nonfatal myocardial infarction, reinfarction, angina, stroke, end-stage renal disease, and morbidity and mortality associated with heart failure. ACE inhibitors are generally well tolerated and have few contraindications.
