In order to determine the prevalence of overt and subclinical hypothyroidism, and isolated hypothyroxinemia during pregnancy, thyroid hormone reference values established by UMAE HGO4, IMSS in Mexico City and those suggested by the American Thyroid Association (ATA) were used. All pregnant patients, whose thyroid function was measured and whose pregnancy was monitored and resolved in UMAE HGO4, IMSS from 1 January to 31 December 2013, were included. Significant differences (p = .00419) were observed in the frequency of subclinical hypothyroidism, being higher when using ATA criteria (18...

INTRODUCTION: Multiple Sclerosis (MS) is one of the most common autoimmune diseases affecting the central nervous system. The prevalence of it is increasing in our country too. The pain from disorders can affect quality of life. Several studies have pointed to the improvement of patients through educational intervention. This study attempted to evaluate the effectiveness of an educational intervention based on raising the awareness and self-efficacy for pain control among patients with multiple sclerosis during 2015 under the coverage of Isfahan MS Society (IMSS)...

INTRODUCTION: Obesity is a chronic, complex, and multifactorial disease, characterized by excess body fat. Diverse studies of the human genome have led to the identification of susceptibility genes that contribute to obesity. However, relatively few studies have addressed specifically the association between the level of expression of these genes and obesity. MATERIAL AND METHODS: We studied 160 healthy and obese unrelated Mexican children aged 6 to 14 years. We measured the transcriptional expression of 20 genes associated with obesity, in addition to the biochemical parameters, in peripheral white blood cells...

We here compared pathogenic (p) and non-pathogenic (np) isolates of Entamoeba histolytica to identify molecules involved in the ability of this parasite to induce amoebic liver abscess (ALA)-like lesions in two rodent models for the disease. We performed a comprehensive analysis of 12 clones (A1-A12) derived from a non-pathogenic isolate HM-1:IMSS-A and 12 clones (B1-B12) derived from a pathogenic isolate HM-1:IMSS-B. "Non-pathogenicity" included the induction of small and quickly resolved lesions while "pathogenicity" comprised larger abscess development that overstayed day 7 post infection...

OBJECTIVE: To estimate the disease burden of cancer in the affiliate population of the Mexican Social Security Institute (Instituto Mexicano del Seguro Social, IMSS) in 2010 by delegation. MATERIALS AND METHODS: The Disability-Adjusted Life Years (DALYs), Years of Life Lost (YLL) due to premature mortality and Years Lived with Disability/Disease (YLD) for 21 specific cancers and a subgroup of other malignant neoplasms were calculated based on the methodology of the Global Burden of Disease Study (GBD) for each of the 35 delegations of the IMSS...

INTRODUCTION: The increasing burden of dengue fever (DF) in the Americas, and the current epidemic in previously unaffected countries, generate major costs for national healthcare systems. There is a need to quantify the average cost per DF case. In Mexico, few data are available on costs, despite DF being endemic in some areas. Extrapolations from studies in other countries may prove unreliable and are complicated by the two main Mexican healthcare systems (the Secretariat of Health [SS] and the Mexican Social Security Institute [IMSS])...

Tuberculous meningitis (TBM) is the most severe form of tuberculosis. It is caused by Mycobacterium tuberculosis (M. tuberculosis; MT) and it is very difficult to diagnose. The symptoms are similar to other infectious neurological diseases, such as neurocysticercosis, neuroborreliosis, or herpes viral infection. The aim of this study was to identify tuberculosis (TB) in cases of meningitis with clinical and laboratory evidence suggestive of TBM, and to confirm our findings with molecular tests for TB infection...

OBJECTIVE: To estimate the direct costs related to hospitalizations for diabetes mellitus and its complications in the Mexican Institute of Social Security METHODS: The hospital care costs of patients with diabetes mellitus using diagnosis-related groups in the IMSS (Mexican Institute of Social Security) and the hospital discharges from the corresponding E10-E14 codes for diabetes mellitus were estimated between 2008-2013. Costs were grouped according to demographic characteristics and main condition, and were estimated in US dollars in 2013...

BACKGROUND: The prevalence of diabetes among adults in Mexico has increased markedly from 6.7 % in 1994 to 14.7 % in 2015. Although the main diabetic complications can be prevented or delayed with timely and effective primary care, a high percentage of diabetic patients have developed them imposing an important preventable burden on Mexican society and on the health system. This paper estimates the financial and health burden caused by potentially preventable hospitalisations due to diabetic complications in hospitals operated by the largest social security institution in Latin America, the Mexican Institute of Social Security (IMSS), in the period 2007-2014...

BACKGROUND: The IMSS performs systematically the data updating of patients with renal replacement therapy (RRT) by an electronic record management referred as: Census patients with Chronical Renal Failure (CIRC) which aims to meet the prevalence of patients with chronic renal failure and the behavior of RRTat the IMSS. METHODS: A retrospective study includes 212 secondary hospitals with dialysis programs, with both pediatric and adult patients. CIRC data obtained from January to December 2014, number and nominal bonds of peritoneal dialysis (PD) and hemodialysis (HD)...

BACKGROUND: Recent studies considered hyperbilirubinemia as a marker to identify the presence of perforated appendix. The aim of the study is to verify that the presence of hyperbilirubinemia is a useful marker to identify the presence of perforated appendix before surgery, and thereby, provide early treatment to avoid progression of the disease and its complications. METHODS: This is a retrospective study, which identified 225 patients, who met the inclusion and exclusion criteria, from January 2012 to October 2014 at the IMSS General Hospital 29, taking into account laboratory results and postoperative, performing a univariate, bivariate and multivariate analysis...

AIM: To investigate whether a diagnostic delay is associated with a poor outcome in Crohn's disease (CD). METHODS: Medical and socioeconomic characteristics as well as medications and need for surgery of consecutive CD adults patients followed in three referral centers were prospectively recorded using an electronic database (Focus_MICI(®)). A long diagnostic delay was defined by the upper quartile. We compared patients with long diagnostic delay to those with earlier diagnosis regarding the time to: (1) first intestinal surgery, (2) first use of immunosuppressants (IMSs), and (3) first use of anti-tumor necrosis factor (anti-TNF) therapy using the Kaplan-Meier test and the log-rank test...

INTRODUCTION: For the treatment of obstructive hydronephrosis that compromises renal function, procedures are required to decrease pressure such as intrarenal ultrasound-guided percutaneous nephrostomy, which leads to complications like any procedure. General objective: To determine the complications of patients undergoing ultrasound-guided percutaneous nephrostomy and factors associated with their development. MATERIAL AND METHODS: Cross-analytical, observational, retrospective study that included patients undergoing ultrasound-guided percutaneous nephrostomy in UMAE 25 IMSS, from 1 March, 2013 to 1 March, 2014...
