Gaucher Disease: Identification and Novel Variants in Mexican and Spanish Patients.

Background: Gaucher disease (GD) is the most prevalent lysosomal storage disorder, affecting all ethnic groups, although its prevalence is higher in Ashkenazi Jewish populations. Three clinical forms of GD have been described: Type 1 non-neuronopathic, type 2 acute neuronopathic, and type 3 subacute neuronopathic. An autosomal recessive disorder is caused by variants in the human glucocerebrosidase gene (GBA; MIM*606463) located on chromosome 1q21, resulting from deficit or lack of activity of the β-glucocerebrosidase enzyme, leading to the accumulation of glucocerebroside substrate in the cells of the macrophage-monocyte system.

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).

Comparison of combined spinal and general anesthesia block and combined epidural and general anesthesia block in laparoscopic cholecystectomy.

Objective: Combined spinal and general anesthesia block (CSGAB) and combined epidural and general anesthesia block (CEGAB) in laparoscopic cholecystectomy were compared.

Material And Methods: Forty patients were randomly selected (ASA physical status I-II) to receive sevoflurane plus 10 to 15 mg of bupivacaine weighed at 0.5% and 20 microg of fentanyl (CSGAB) or sevoflurane plus 150 mg of ropivacaine and 1 microg/kg of fentanyl (CEGAB).

[Frequency of intestinal helminthiasis and its association with iron deficiency and malnutrition in children from western Mexico].

Objective: To determine intestinal helminthiasis frequency and its association with malnutrition and iron deficiency.

Material And Methods: An analytical cross-over study was carried out on children in the municipality of Comala, Colima, Mexico. Coproparasitoscopic exams in series of three using the Kato-Katz technique were performed in all children.

[Comparative effectiveness of 0.1% metilprednisolone aceponate and 0.05% betamethasone dipropionate among children with nonretractable prepuce].

Objective: To compare clinical improvement between treatment with metilprednisolone aceponate vs. betamethasone dipropionate among children with nonretractable prepuce.

Material And Methods: Between August 2001 and November 2002, we carried out a double blind and controlled clinical trial in 34 children with a diagnosis of nonretracable prepuce.

F-wave and H-reflex alterations in recently diagnosed diabetic patients.

Objective: To explore the frequency of F-wave and H-reflex alterations in recently diagnosed type 2 diabetes mellitus patients and to determine if the alterations are dependent on the levels of glycemia.

Methods: A cross-sectional study was carried out on 50 asymptomatic patients, with a mean age of 45.4 +/- 9.

Modified mattress suture technique to correct anterior septal deviation.

The purpose of this study was to evaluate the efficacy of a modified mattress suture technique in septal anterior deviation correction and to compare it with the Hinderer technique. This was a randomized, controlled, single-blind clinical trial. Fifty patients with anterior septal deviation were assigned to one of two surgery treatment groups: in group A, 25 patients underwent anterior septoplasty with modified mattress suture technique; and in group B, 25 patients underwent anterior septoplasty with the Hinderer technique.

Blink reflex alterations in recently diagnosed diabetic patients.

Objective: The aim of the present study was to determine the frequency of blink reflex alterations and to examine the influence of hyperglycemia in inducing the alterations in recently diagnosed Type 2 diabetes mellitus patients.

Methods: A cross-sectional study was carried out on patients having asymptomatic diabetes with a period of evolution under 10 years. In all 47 patients (26 women and 21 men), serum glycemia levels were determined and the latency onset of the blink reflex components were measured.

Frequency of, indications for and clinical epidemiological characteristics of first time cesarean section, compared with repeated cesarean section.

Unlabelled: The aim of this study was to determine the frequency of, indications for and clinical epidemiological characteristics in patients having their first cesarean section (FCS) and then to compare the data with that found in patients with repeated cesarean section (RCS).

Patients And Methods: A cross-sectional study was carried out. 493 pregnant patients who gave birth by cesarean section or vaginal delivery were seen.

[White-coat hypertension and risk factors in recently diagnosed hypertensive patients].

Objective: To determine the frequency of white-coat hypertension (WCH) and associated risk factors in recently diagnosed hypertensive patients.

Material And Methods: A cross-sectional study was carried out from January 1997 to December 1998. The reference population consisted of 195 patients presenting with systemic arterial hypertension (SAH) of less than 1-month evolution and receiving no medical treatment.

UVB photoprotection with antioxidants: effects of oral therapy with d-alpha-tocopherol and ascorbic acid on the minimal erythema dose.

Ultraviolet radiation absorption is responsible for the production of free radicals in damaged cells. This side effect may be neutralized using antioxidant substances. It has been reported that ascorbic acid and d-alpha-tocopherol scavenge reactive oxygen species.

[Risk factors for cesarean section: epidemiologic approach].

The increase in frequency of cesareans that has been noted through 70's, not diminished--like it was expected--perinatal morbidity and mortality. The most important indications to cesarean are distocias, previous cesarean and fetal stress. In 1998 frequency of cesarean deliveries in our hospital was 35% of the pregnancy attended.

[Perinatal mortality 1 in Colima, Col. Case-control study].

Unlabelled: Perinatal mortality 1 (PM1) includes deads occurred from 28th week of gestation to 1st week of extrauterine life. The aim of this study was to describe, from medical records, clinical-epidemiological characteristics of 19 perinatal mortality 19 cases and 36 controls occurred in 1998 at a General Hospital.

Results: Interruption of the fetal-placental circulation, cardiopathy and ventricular hemorrhages were the main causes of PM1.

[Neoplasms and dysplasias of the gallbladder and their relationship with lithiasis. A case-control clinicopathological study].

Background: A strong association has been reported between gallbladder carcinoma, premalignant epithelial or metaplasic inflammatory lesions and cholelithiasis, varying the incidence among different ethnic groups.

Purpose: To determine the frequency of association between such lesions and gallbladder lithiasis.

Material And Methods: We examined histopathologic changes in 1,367 cholecystectomy specimens with (1,096) or without (271) lithiasis and established its frequency of association, correlating with main clinical data.
