A retrospective study was performed to determine the etiology of failed primary anterior cruciate ligament (ACL) reconstruction and evaluate the clinical results of revision ACL surgery. From January 1989 to January 1996, 90 patients with failed ACL reconstructions underwent revision ACL surgery. The etiology of failed ACL reconstruction included 47 surgical technical errors, 22 traumatic reinjuries, 7 lack of graft incorporation, 3 loss of motion, 3 related to synthetic grafts, and 8 alignment or combined ligamentous instability patterns not addressed. Of 52 revision ACL patients with minimum 2-year follow-up, 43responded to a questionnaire and underwent a comprehensive physical examination. The Hospital for Special Surgery knee ligament evaluation revealed 63% good/excellent results. Objective laxity test revealed 77% of all patients had 0/ϩ ϩ1 grade on Lachman and a mean 2.86-mm KT 1000. The overall results of revision ACL surgery are encouraging in providing symptomatic relief and restoring stability; however, they are significantly lower than primary ACL surgery.
In patients with bacterial peritonitis, administration of prophylactic oral fluconazole throughout the time they received antibiotics significantly prevented the appearance of secondary fungal peritonitis.
Abstract. Coinfection with tuberculosis in some countries occurs in 8-15% of human immunodeficiency virus (HIV) -infected patients who have histoplasmosis. This coinfection interferes with prompt diagnosis, and treatment is difficult because of drug interactions. We retrospectively reviewed the cases of 14 HIV-infected patients who had concomitant tuberculosis and histoplasmosis. The most frequent clinical manifestations were weight loss (85.7%), asthenia (78.5%), and fever (64.2%). The diagnosis of histoplasmosis was made primarily by histopathology (71.4%), and the diagnosis of tuberculosis was made by means of direct microscopic examination (71.4%). Death occurred in two patients, and relapse of both infections occurred in one patient. Moxifloxacin was substituted for rifampicin in six patients, with good outcomes noted for both infections. The clinical presentation does not readily identify acquired immunodeficiency syndrome (AIDS) patients who have tuberculosis and histoplasmosis. The use of a fluoroquinolone as an alternative agent in place of rifampicin for tuberculosis allows effective therapy with itraconazole for histoplasmosis.
BackgroundAntiretroviral therapy (ART) has modified the natural history of HIV-infection: the incidence of opportunistic infections (OIs) has decreased and mortality associated to HIV has improved dramatically. The reasons for hospitalization have changed; OIs are no longer the most common reason for admission. This study describes the patient population, admission diagnosis and hospital course of HIV patients in Colombia in the ART era.MethodsPatients admitted with HIV/AIDS at six hospitals in Medellin, Colombia between August 1, 2014 and July 31, 2015 were included. Demographic, laboratory, and clinical data were prospectively collected.Results551 HIV-infected patients were admitted: 76.0% were male, the median age was 37 (30–49). A new diagnosis of HIV was made in 22.0% of patients during the index admission. 56.0% of patients of the entire cohort had been diagnosed with HIV for more than 1 year and 68.9% were diagnosed in an advanced stage of the disease. More than 50.0% of patients had CD4 counts less than 200 CD4 cells/μL and viral loads greater than 100,000 copies. The main reasons for hospital admissions were OIs, tuberculosis, esophageal candidiasis and Toxoplasma encephalitis. The median hospital stay was 14 days (IQR 8–23). Admission to the intensive care unit (ICU) was required in 10.3% of patients and 14.3% were readmitted to the hospital; mortality was 5.4%.ConclusionsSimilar to other countries in the developing world, in Colombia, the leading cause of hospitalization among HIV-infected patients remain opportunistic infections. However, in-hospital mortality was low, similar to those described for high-income countries. Strategies to monitor and optimize the adherence and retention in HIV programs are fundamental to maximize the benefit of ART.
This study generated a susceptibility baseline in response to therapy with Coartem (artemether-lumefantrine) with numerical reference values, which will allow data comparison with future studies to systematically monitor changes in the parasite and to provide an early alert to the health authorities.
Twenty-five children with serious Gram-negative infections were treated in a prospective study with amikacin 20 mg/kg administered in a single daily dose as a 30 min iv infusion for 4 to 12 days. In nine cases the amikacin was combined with beta-lactam antibiotics. Escherichia coli were the most frequent bacteria isolated followed by K. pneumoniae, Providencia and Enterobacter spp. and Pseudomonas aeruginosa with MICs ranging from 1 to 16 mg/l. Mean (+/- S.D.) peak and trough concentrations of days 1 and 4 of therapy ranged from 49 +/- 13.5 to 53.6 +/- 13.4 mg/l and 6 + 1.4 to 7.7 +/- 4.1 mg/l respectively. All patients were clinically and bacteriologically cured. No significant adverse reactions were observed. The results suggest that administration of a single daily dose of 20 mg/kg amikacin should be considered practical and safe in children. Further studies are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
