Clinical and microbiological characteristics of community-acquired pneumonia associated with Streptococcus pneumoniae in adult patients in Mexico.

The aim of this study was to assess the risk factors and clinical and microbiological characteristics of community-acquired pneumonia (CAP) in adult patients in Mexico. Streptococcus pneumoniae classified as the causative agent of CAP in adult patients and patients with invasive S. pneumoniae isolates presented to three tertiary teaching hospitals during the 15-year study period were selected.

[MGIT and other methods for diagnosing tuberculosis in a private hospital system with low incidence].

Background: Tuberculosis (TB) is still a threat to public health; in 2014 caused 1.5 million deaths worldwide; in hospitals where the prevalence of TB is low, it is appropriate to evaluate the effectiveness of tests to diagnose it.

Methods: We reviewed reports of airway clinical specimens sent for studies of tuberculosis to the microbiology laboratory from Tec Salud System private hospitals (400 beds) in the metropolitan area of ​​Monterrey, NL, from May 2012 to December 2015.

[Case series of Clostridium difficile NAP1/027/BI with novels treatments].

Background: Clostridium difficile is a spore-forming bacterium, producing exotoxins, causing potentially fatal nosocomial diarrhea. They have recently reported outbreaks of C. difficile ribotype 027, which is characterized by a hypervirulent strain and high resistance to standard therapy.

[Role of anaerobic blood culture in the simultaneous blood culture taking for the diagnosis of bacteremia].

Background: Harboring a high mortality, the incidence of sepsis is increasing; thus detection, identification and susceptibility tests of the involved microorganisms become urgent.

Methods: We reviewed the records from January 2013 until July 2014 of a total of 4110 blood culture bottles taken from adult patients in a private tertiary hospital.

Results: Growth of microorganisms was observed in 559 bottles (12.

Surgical site infection rates in four Mexican cities: findings of the International Nosocomial Infection Control Consortium (INICC).

From January 2005 to December 2010, we conducted a prospective cohort surveillance study on surgical site infections (SSIs) in five hospitals, all of which were members of the International Nosocomial Infection Control Consortium (INICC) in four cities in Mexico. Data were recorded from hospitalized patients using the methods and definitions of the Centers for Disease Control and Prevention's National Healthcare Safety Network (CDC-NHSN) for SSIs. Surgical procedures (SPs) were classified into 11 types according to the ICD-9 criteria.

[Necrotizing fasciitis, myositis, arthritis, and streptococcal toxic shock syndrome caused by group G Streptococcus. Report of one case].

Background: Necrotizing fasciitis (NF), myositis, and streptococcal toxic shock syndrome (STSS) associated with group G ß-hemolytic streptococcus (GGS) occasionally coincide.

Clinical Case: We describe a case of GGS simultaneously occurring with NF, myositis, arthritis, and STSS in an 83-year-old woman with sequelae of cerebrovascular disease, hospitalized after two days of fever and with a painful swollen left foot. She was hypotensive, her foot had purplish discoloration, which showed blisters spreading to the lower third of the leg, and no crepitus was present.

[Necrotizing fasciitis and group A streptococcal toxic shock syndrome in two patients without risk factors].

Necrotizing fasciitis associated to group A streptococcus (S. pyogenes) infection is a deep-seated infection of the subcutaneous tissue that results in progressive destruction of fascia and fat, with a high mortality rate due to a rapid progression of the illness to shock and multiple organ dysfunction. The challenge is to perform a prompt diagnosis because it is often confused with a minor soft-tissue infection.

[Catheter-associated bloodstream infections. Review of five-year surveillance among hospitalized patients].

Background: Catheter related infections (CRI) and bloodstream infection (BSI) associated to central venous catheter (CVC) is cause of frequent hospital-acquired infection (HAI) and a major reason of morbidity and mortality among patients and it is itself an indicator of quality health care.

Objective: To determine the incidence of CRI and BSI and to identify the hospital areas where they occurred over a five-year period.

Methods: A prospective study from 2004 to 2008 in a population of hospitalized patients who required the use of CVC was made.

Cutaneous zygomycosis in immunocompetent patients in Mexico.

We report three cases of traumatic cutaneous zygomycosis related to soil-contaminated skin lesions occurring after automobile accidents in individuals with no underlying disorders, which showed delayed development and diagnosis in comparison with typical zygomycosis cutaneous lesions.

[Antibiotic resistance of Escherichia coli from community-acquired urinary tract infections. What antimicrobial to use?].

Objective: Determine antibiotic resistance of community-acquired uropathogen Escherichia coli and infer therapeutic options.

Material And Methods: E. coli strains isolated from urine during a one-year period were studied.

[Cyclosporidiosis: clinical and diagnostic characteristics of an epidemic outbreak].

Background: Cyclospora cayetanensis, a coccidian parasite, has increasingly been recognized as a cause of gastrointestinal tract illness. We describe a group of patients with this infection.

Objectives: Our aim was to describe the observed clinical course and spectrum of the disease.
