[Scorpionism causing severe acute flaccid paralysis. Case report].

Background: Scorpionism is a public health problem in various regions of the world, being Mexico the country with the highest number of cases. Clinical manifestations range from local symptoms to severe disease with an impact on cardiovascular, respiratory and neurological level, and even death. There are no reports of acute flaccid paralysis as a manifestation of the clinical picture of the scorpion sting of the Centruroides gender, Family Buthidae, highly toxic, causes high rates of morbidity and mortality in our region.

[Trend of antimicrobial susceptibility in a neonatal and pediatric intensive care unit].

Background: Nosocomial infections in intensive care units are a health problem worldwide due to their incidence, prevalence and clinical impact. The objective of this article was to describe the trend of antimicrobial susceptibility during a 10-years period in both a pediatric and a neonatal intensive care unit.

Methods: This is a follow-up cohort study.

Effectiveness of botulinum toxin (type-A) administered by the fixed-site dosing approach versus the muscle area identification.

Introduction: Botulinum toxin is widely used in glabellar musculature. The authors express the need to individualize the approach by means of muscular identification to improve effectiveness. Despite these guidelines, the fixed-point technique is still used.

[Circadian rhythm of blood pressure in patients with chronic hypertension and pregnancy].

Background: Ambulatory blood pressure monitoring during 24 hours shows a blood pressure variability. The prevalence of chronic hypertension in pregnant women is 1-5%, so it is important to know the changes in blood pressure and cardiovascular risk and prevent complications to the mother and fetus.

Objective: To know the circadian rhythm of the blood pressure in the chronic hypertensive pregnant patients, through the ambulatory blood pressure monitoring.

Procollagen Type I and III Aminoterminal Propeptide Levels and Severity of Interstitial Lung Disease in Mexican Women With Progressive Systemic Sclerosis.

Background: Interstitial lung disease (ILD) is a frequent complication in progressive systemic sclerosis (SSc), being present in 25% to 90% of cases.

Objectives: To evaluate whether serum levels of procollagen typei and iii aminoterminal propeptide (PINP and PIIINP) correlate with severity and patterns of ILD in Mexican women with SSc.

Methods: Thirty three SSc patients were assessed for disease characteristics and anti-topoisomerase antibodies (topoi), and also underwent pulmonary function tests and high-resolution computed tomography (HRCT).

[Prognosis in pediatric traumatic brain injury. A dynamic cohort study].

Background: traumatic brain injury is a main cause of hospital admission and death in children. Our objective was to identify prognostic factors of pediatric traumatic brain injury.

Methods: this was a dynamic cohort study of traumatic brain injury with 6 months follow-up.

[Motives of requirement for health care consultations and factors associated to mortality due to poisoning].

Background: The poisoning is a public health problem. This problem requires continuous evaluation to decrease it. Our objective was to identify causes of requirement for health care consults and factors associated to mortality due to poisoning.

[Assessment of serum IgG activity correlation against cyclic citrullinated peptide antibodies, topoisomerase I and centromere proteins in Mexican patients with progressive systemic sclerosis].

Objective: To evaluate sera titers for antibodies anti-cyclic citrullinated peptide and their correlation against sera levels of anti-topoisomerase I and anti-centromere antibodies in Mexican patients with systemic sclerosis.

Patients And Methods: Consecutive outpatients with systemic sclerosis who attending to rheumatology clinic at a second level hospital facility. The antibodies anti-cyclic citrullinated peptide, anti-topoisomerase I and anti-centromere were determined by enzymatic immunoassay (ELISA).

Clinical competence for autoimmune and non-autoimmune rheumatic disorders in primary care.

Objective: To evaluate the competence of the primary care physicians for the evaluation of rheumatic disorders.

Participants And Methods: In a cross-sectional survey we included primary care physicians working at the official Mexican Social Security Institute that provides nation-wide health-care for salaried workers. Four hospitals from 23 potentially eligible primary-care hospitals in Guadalajara, Jalisco, Mexico, were randomly selected.

Hyperhomocysteinemia in ankylosing spondylitis: prevalence and association with clinical variables.

We evaluated the prevalence and characteristics associated with hyperhomocysteinemia in ankylosing spondylitis (AS). Ninety-seven patients with AS were compared with 97 controls. The assessment included clinical characteristics, disease activity (BASDAI), functioning (BASFI), history of drugs, and erythrocyte sedimentation rate (ESR).
