Iodine status and thyroid function among Spanish schoolchildren aged 6-7 years: the Tirokid study.

I deficiency is still a worldwide public health problem, with children being especially vulnerable. No nationwide study had been conducted to assess the I status of Spanish children, and thus an observational, multicentre and cross-sectional study was conducted in Spain to assess the I status and thyroid function in schoolchildren aged 6-7 years. The median urinary I (UI) and thyroid-stimulating hormone (TSH) levels in whole blood were used to assess the I status and thyroid function, respectively. A FFQ was used to determine the consumption of I-rich foods. A total of 1981 schoolchildren (52 % male) were included. The median UI was 173 µg/l, and 17·9 % of children showed UI<100 µg/l. The median UI was higher in males (180·8 v. 153·6 µg/l; P<0·001). Iodised salt (IS) intake at home was 69·8 %. IS consumption and intakes of ≥2 glasses of milk or 1 cup of yogurt/d were associated with significantly higher median UI. Median TSH was 0·90 mU/l and was higher in females (0·98 v. 0·83; P<0·001). In total, 0·5 % of children had known hypothyroidism (derived from the questionnaire) and 7·6 % had TSH levels above reference values. Median TSH was higher in schoolchildren with family history of hypothyroidism. I intake was adequate in Spanish schoolchildren. However, no correlation was found between TSH and median UI in any geographical area. The prevalence of TSH above reference values was high and its association with thyroid autoimmunity should be determined. Further assessment of thyroid autoimmunity in Spanish schoolchildren is desirable.

New methodology for assessing the environmental burden of cement mortars with partial replacement of coal bottom ash and fly ash.

This paper assess the mechanical an environmental behaviour of cement mortars manufactured with addition of fly ash (FA) and bottom ash (BA), as partial cement replacement (10%, 25% and 35%). The environmental behaviour was studied by leaching tests, which were performed under several temperature (23 °C and 60 °C) and pH (5 and 10) conditions, and ages (1, 2, 4 and 7 days). Then, the accumulated amount of the different constituents leached was analysed. In order to obtain an environmental burden (EB) value of each cement mixture, a new methodology was developed. The EB value obtained is related to the amount leached and the hazardous level of each constituent. Finally, the integral study of compressive strength and EB values of cement mixtures allowed their classification. The results showed that mortars manufactured with ordinary Portland cement (OPC) and with coal BA had similar or even better environmental and mechanical behaviour than mortars with FA. Therefore, the partial replacement of cement by BA might be as suitable or even better as the replacement by FA.

Mediterranean diet adherence in individuals with prediabetes and unknown diabetes: the Di@bet.es Study.

BACKGROUND AND AIMS: Mediterranean diet (MedDiet) is causally related to diabetes and is a dietary pattern recommended to individuals with diabetes. We investigated MedDiet adherence in individuals with prediabetes and unknown (PREDM/UKDM) or known diabetes (KDM) compared to those with normal glucose metabolism (NORMAL). METHODS: This was a national, population-based, cross-sectional, cluster-sampling study. MedDiet adherence was scored (MedScore, mean ± SD 24 ± 5) using a qualitative food frequency questionnaire. Logistic regression was used to examine the association between MedScore and PREDM/UKDM or KDM versus control subjects. RESULTS: We evaluated 5,076 individuals. Mean age was 50 years, 57% were female, 826 (582/244) were PREDM/UKDM, 478 were KDM and 3,772 were NORMAL. Mean age increased across MedScore tertiles (46, 51 and 56 years, p < 0.0001). Higher age-adjusted adherence to MedDiet (5-unit increment in the MedScore) was associated with lower and nondifferent odds (OR, 95% CI) of prevalent PREDM/UKDM (0.88, 0.81-0.96, p = 0.001) and KDM (0.97, 0.87-1.07, p = 0.279), respectively, compared to individuals in the NORMAL group. CONCLUSIONS: In a representative sample of the whole Spanish population, MedDiet adherence is independently associated with PREDM/UKDM. Therapeutic intervention may be, in part, responsible for the lack of differences in adherence observed between the KDM and NORMAL groups. However, reverse causation bias cannot be ruled out in cross-sectional studies.

Physical activity patterns in type 1 diabetes in Spain: The SED1 study.

AIMS: To describe the physical activity (PA) frequency and intensity in the Spanish type 1 diabetes mellitus (T1D) population and its association with their glycemic control. METHODS: A cross-sectional observational study was carried out in 75 Spanish public hospitals (the SED1 study). T1D patients over 14years of age self-completed the International Physical Activity Questionnaire (IPAQ) to determine their level of exercise. The relationship between PA frequency and intensity in T1D patients and glycemic control and the diabetes therapeutic education received were analyzed. RESULTS: A total of 592 patients were evaluable. A 6.8% of the sample performed light PA, 20.9% moderate and 72.3% vigorous. Estimated PA presented a high inter-individual variability. Men consumed more energy (METS) than women, these differences being more noticeable in vigorous METS (2865.80 in men vs 1352.12 in women). Women invested more min/week in the domestic and garden area (639.03 vs 344.39, p = 0,022). A correlation between glycemic control and the METs was not observed. CONCLUSIONS: The Spanish T1D population performed PA in a higher frequency and intensity than the general population. A relationship between PA and glycemic control couldn´t be shown. However, limitations of the study should be kept in mind to discard a long-term positive influence.

Evaluating remote facilitation intensity for multi-national translation of nurse-initiated stroke protocols (QASC Australasia): a protocol for a cluster randomised controlled trial.

BACKGROUND: Facilitated implementation of nurse-initiated protocols to manage fever, hyperglycaemia (sugar) and swallowing difficulties (FeSS Protocols) in 19 Australian stroke units resulted in reduced death and dependency for stroke patients. However, a significant gap remains in translating this evidence-based care bundle protocol into standard practice in Australia and New Zealand. Facilitation is a key component for increasing implementation. However, its contribution to evidence translation initiatives requires further investigation. We aim to evaluate two levels of intensity of external remote facilitation as part of a multifaceted intervention to improve FeSS Protocol uptake and quality of care for patients with stroke in Australian and New Zealand acute care hospitals. METHODS: A three-arm cluster randomised controlled trial with a process evaluation and economic evaluation. Australian and New Zealand hospitals with a stroke unit or service will be recruited and randomised in blocks of five to one of the three study arms-high- or low-intensity external remote facilitation or a no facilitation control group-in a 2:2:1 ratio. The multicomponent implementation strategy will incorporate implementation science frameworks (Theoretical Domains Framework, Capability, Opportunity, Motivation - Behaviour Model and the Consolidated Framework for Implementation Research) and include an online education package, audit and feedback reports, local clinical champions, barrier and enabler assessments, action plans, reminders and external remote facilitation. The primary outcome is implementation effectiveness using a composite measure comprising six monitoring and treatment elements of the FeSS Protocols. Secondary outcome measures are as follows: composite outcome of adherence to each of the combined monitoring and treatment elements for (i) fever (n=5); (ii) hyperglycaemia (n=6); and (iii) swallowing protocols (n=7); adherence to the individual elements that make up each of these protocols; comparison for composite outcomes between (i) metropolitan and rural/remote hospitals; and (ii) stroke units and stroke services. A process evaluation will examine contextual factors influencing intervention uptake. An economic evaluation will describe cost differences relative to each intervention and study outcomes. DISCUSSION: We will generate new evidence on the most effective facilitation intensity to support implementation of nurse-initiated stroke protocols nationwide, reducing geographical barriers for those in rural and remote areas.

Prevalence of diabetes mellitus and impaired glucose regulation in Spain: the Di@bet.es Study.

AIMS/HYPOTHESIS: The Di@bet.es Study is the first national study in Spain to examine the prevalence of diabetes and impaired glucose regulation. METHODS: A population-based, cross-sectional, cluster sampling study was carried out, with target population being the entire Spanish population. Five thousand and seventy-two participants in 100 clusters (health centres or the equivalent in each region) were randomly selected with a probability proportional to population size. Participation rate was 55.8%. Study variables were a clinical and demographic structured survey, lifestyle survey, physical examination (weight, height, BMI, waist and hip circumference, blood pressure) and OGTT (75 g). RESULTS: Almost 30% of the study population had some carbohydrate disturbance. The overall prevalence of diabetes mellitus adjusted for age and sex was 13.8% (95% CI 12.8, 14.7%), of which about half had unknown diabetes: 6.0% (95% CI 5.4, 6.7%). The age- and sex-adjusted prevalence rates of isolated impaired fasting glucose (IFG), isolated impaired glucose tolerance (IGT) and combined IFG-IGT were 3.4% (95% CI 2.9, 4.0%), 9.2% (95% CI 8.2, 10.2%) and 2.2% (95% CI 1.7, 2.7%), respectively. The prevalence of diabetes and impaired glucose regulation increased significantly with age (p < 0.0001), and was higher in men than in women (p < 0.001). CONCLUSIONS/INTERPRETATION: The Di@bet.es Study shows, for the first time, the prevalence rates of diabetes and impaired glucose regulation in a representative sample of the Spanish population.

Rhabdomyolysis in a patient with McArdle's disease. / Rabdomiólisis en un paciente con enfermedad de McArdle.

INTRODUCTION: McArdle's disease or glycogenosis type V is a rare disease due to deficiency of muscle myophosphorylase leading to inability to degrade glycogen at this level. Patients have fatigue, pain, and cramps on a regular basis. In addition, after intense exercise or stressful situation, they are exposed to cellular lysis. This can occur in the form of rhabdomyolysis and myoglobinuria, a potentially serious clinical syndrome if not treated quickly. CASE EVALUATION: We present the care plan of a 38-year-old man with McArdle's disease and secondary rhabdomyolysis on physical exercise, which required attention in the Emergency Department for 24 hours, as well as his subsequent admission to the ward. A nursing evaluation was performed following the care model of Virginia Henderson. DIAGNOSIS: Priority was given to nurse diagnoses: (00016) deterioration of urinary elimination, (00092) activity intolerance, (00093) fatigue and (00132) acute pain; and potential complication: risk of acute renal failure. PLANNING: The Care Plan is developed following the NANDA-NIC-NOC methodology, with special attention to alterations in the elimination and musculoskeletal system. The diuresis is monitored. Fluid replenishment is performed, and analgesic medication is given. DISCUSSION: There is little literature on the nursing care of patients with McArdle's disease, which has limited the comparison of our results with those of other authors. However, given the good response of the subject through fluid replacement, optimal pain control and rest, they made a rapid recovery.

Fatty liver index as a predictor for type 2 diabetes in subjects with normoglycemia in a nationwide cohort study.

Our aim was to evaluate whether fatty liver index (FLI) is associated with the risk of type 2 diabetes (T2DM) development within the Spanish adult population and according to their prediabetes status; additionally, to examine its incremental predictive value regarding traditional risk factors. A total of 2260 subjects (Prediabetes: 641 subjects, normoglycemia: 1619 subjects) from the Di@bet.es cohort study were studied. Socio-demographic, anthropometric, clinical data and survey on habits were recorded. An oral glucose tolerance test was performed and fasting determinations of glucose, lipids and insulin were made. FLI was calculated and classified into three categories: Low (< 30), intermediate (30-60) and high (> 60). In total, 143 people developed diabetes at follow-up. The presence of a high FLI category was in all cases a significant independent risk factor for the development of diabetes. The inclusion of FLI categories in prediction models based on different conventional T2DM risk factors significantly increase the prediction power of the models when all the population was considered. According to our results, FLI might be considered an early indicator of T2DM development even under normoglycemic condition. The data also suggest that FLI could provide additional information for the prediction of T2DM in models based on conventional risk factors.

Incidence of diabetes mellitus in Spain as results of the nation-wide cohort di@bet.es study.

Our aim was to determine the incidence of type 2 diabetes mellitus in a nation-wide population based cohort from Spain (di@bet.es study). The target was the Spanish population. In total 5072 people older than 18 years,were randomly selected from all over Spain). Socio-demographic and clinical data, survey on habits (physical activity and food consumption) and weight, height, waist, hip and blood pressure were recorder. A fasting blood draw and an oral glucose tolerance test were performed. Determinations of serum glucose were made. In the follow-up the same variables were collected and HbA1c was determined. A total of 2408 subjects participated in the follow-up. In total, 154 people developed diabetes (6.4% cumulative incidence in 7.5 years of follow-up). The incidence of diabetes adjusted for the structure of age and sex of the Spanish population was 11.6 cases/1000 person-years (IC95% = 11.1-12.1). The incidence of known diabetes was 3.7 cases/1000 person-years (IC95% = 2.8-4.6). The main risk factors for developing diabetes were the presence of prediabetes in cross-sectional study, age, male sex, obesity, central obesity, increase in weight, and family history of diabetes. This work provides data about population-based incidence rates of diabetes and associated risk factors in a nation-wide cohort of Spanish population.

[The epidemiology of congenital heart disease in Asturias (Spain) during the period 1990-2004]. / Epidemiología de las cardiopatías congénitas en Asturias durante el período 1990-2004.

INTRODUCTION: Congenital heart diseases (CHDs) are the most common type of birth defect. OBJECTIVE: The purpose of this investigation was to assess the prevalence and trends of CHDs, and to describe the associated malformations and syndromes or sequences in a geographically defined population. MATERIAL AND METHODS: Data were collected from the Asturias Registry of Congenital Defects. The period studied was from 1990 to 2004, and the study population was the 103,452 births of mothers living in the region. Total prevalence and birth prevalence were calculated. RESULTS: A total of 3035 cases with congenital defects were recorded, of these 778 had CHDs. The total prevalence was 75.2 per 10,000 births, with an upward trend during this period. The most common CHDs were: ventricular septal defects (28.8 per 10,000 births), atrial septal defects (10.3 per 10,000 births) and patent ductus arteriosus (6.0 per 10,000 births). A total of 73.6% of CHDs occurred as isolated defects, 12.5% with other congenital defects and 14% were syndromes or sequences. Prenatal diagnosis was effective in only 7.3% (3.8% in isolated cases). CONCLUSIONS: The prevalence of CHDs in Asturias over this period falls within the range reported for other European registries. The apparent increase in prevalence of CHD results mainly from improved diagnosis of minor defects, but there has been no change over time in birth prevalence of more serious defects.

Legumes display common and host-specific responses to the rhizobial cellulase CelC2 during primary symbiotic infection.

Primary infection of legumes by rhizobia involves the controlled localized enzymatic breakdown of cell walls at root hair tips. Previous studies determined the role of rhizobial CelC2 cellulase in different steps of the symbiotic interaction Rhizobium leguminosarum-Trifolium repens. Recent findings also showed that CelC2 influences early signalling events in the Ensifer meliloti-Medicago truncatula interaction. Here, we have monitored the root hair phenotypes of two legume plants, T. repens and M. sativa, upon inoculation with strains of their cognate and non-cognate rhizobial species, R. leguminosarum bv trifolii and E. meliloti, (over)expressing the CelC2 coding gene, celC. Regardless of the host, CelC2 specifically elicited 'hole-on-the-tip' events (Hot phenotype) in the root hair apex, consistent with the role of this endoglucanase in eroding the noncrystalline cellulose found in polarly growing cell walls. Overproduction of CelC2 also increased root hair tip redirections (RaT phenotype) events in both cognate and non-cognate hosts. Interestingly, heterologous celC expression also induced non-canonical alterations in ROS (Reactive Oxygen Species) homeostasis at root hair tips of Trifolium and Medicago. These results suggest the concurrence of shared unspecific and host-related plant responses to CelC2 during early steps of symbiotic rhizobial infection. Our data thus identify CelC2 cellulase as an important determinant of events underlying early infection of the legume host by rhizobia.

[Effectiveness of a school-based program to prevent obesity]. / Efectividad de una intervención escolar contra la obesidad.

INTRODUCTION: Intervention for childhood obesity is a public health priority. The purpose of this study was to evaluate the effectiveness of an elementary school-based intervention against obesity in children. MATERIAL AND METHODS: Non-randomised controlled trial was conducted on children from first to fifth grade from two public schools of Avilés (Spain). The intervention lasted for 2 school years comprising healthy diet workshops, educational chats, educational meetings, informative written material, and promotion of physical activities. Primary outcome measure was body mass index z-score. Secondary outcomes included: obesity and overweight prevalence, waist circumference, dietary habits, and physical activity. RESULTS: A total of 382 (177 girls, 205 boys) out of 526 pupils of both schools were included in the study. Complete anthropometric data were obtained in 340 of the 382 individuals. Compared to children in control group, those in intervention group decreased body mass index z-score from 1.14 to 1.02 (P=.017), and improved KIDMED score from 7.33 to 7.71 points (P=.045). The percentage of students who carried on an optimal diet increased from 42.6% to 52.3% (P=.021). There were no statistical differences in the prevalence of obesity and overweight, or in waist circumference between the intervention and control groups. CONCLUSIONS: This school-based program resulted in modest beneficial changes in body mass index and diet quality.

Effect of directly observed preventive therapy for latent tuberculosis infection in San Francisco.

SETTING: San Francisco TB Clinic instituted a directly observed preventive therapy (DOPT) program for treatment of persons with latent TB infection in 1996. OBJECTIVE: To examine therapy completion for latent tuberculosis infection before and after implementation of the DOPT program. DESIGN: Medical records were analyzed for patients at the San Francisco TB Clinic referred from high-risk sites for the periods 1993-1994 (n = 619) and 1997-June 1998 (n = 460). Treatment completion and time of therapy were analyzed comparing DOPT to self-administered therapy (SAT). RESULTS: More DOPT patients completed treatment (70.3%) than SAT patients (47.9%) (P < 0.001). Controlling for sex, age, race/ethnic group and cohort, patients on DOPT were nearly twice as likely to complete therapy (OR 1.93, 95% CI 1.25-3.00). CONCLUSION: DOPT is a successful strategy. Combined with targeted testing, DOPT can have an important impact in areas with traditionally low rates of treatment adherence.

Tuberculosis prevalence in an urban jail: 1994 and 1998.

SETTING: Despite a continuing decline in tuberculosis (TB) in the US, jails remain a high-risk setting for the identification of active and latent TB infection (LTBI). OBJECTIVE: The purpose of this study was to document the change in TB prevalence in the San Francisco City and County Jail. DESIGN: Two period prevalence analyses were done, for 1994 and 1998. The sample included all persons booked into jail during the two years. The rates of inmates screened and the prevalence of active TB and LTBI by sex and ethnicity were compared using computerized records. RESULTS: Prevalence of active TB was 72.1 per 100000 jail population for 1998, and did not change significantly from 1994. In 1998 one third of active TB cases were found through jail screening. Latinos represented respectively 20.1% and 17.7% of those booked in 1994 and 1998, but 43.0% and 41.7% of inmates with LTBI. In 1998, being Latino (odds ratio 2.9) and male (odds ratio 1.6) were most strongly associated with LTBI. CONCLUSION: Screening for TB among jail inmates is an increasingly valuable clinical and epidemiological tool for case-finding and for identifying persons who would benefit from preventive therapy.

Circadian rhythms of plasma corticosterone at different times after induction of diabetes. Responses to corticoadrenal stimulation in light and dark phases.

In this study we have tried to determine the effects of streptozotocin-induced (50 mg/kg) diabetes (15 and 30 day duration) on circadian rhythms of plasma corticosterone concentrations and on the responsiveness of the adrenal glands to exogenously administered ACTH at the time of maximum and minimum levels of plasma corticosterone. Rats were kept under controlled lighting 12h light/12h dark (12L/12D) and fed ad libitum. The corticosteroid circadian pattern in control (C) rats is characterized as one in which peak corticosterone concentrations occur at the beginning of the dark phase (activity period), with a decrease over the remainder of the 24h period. Circadian rhythmicity of plasma corticosterone concentration was absent in the diabetic rats 15 days after induction (D15 rats), with higher mean levels than the C. However, in the diabetic rats 30 days after induction (D30 rats) there is a recovery of this rhythm with similar acrophase and amplitude to the C rats. One hour after stimulation by ACTH (5 IU/kg) at the time of maximum and minimum levels of plasma corticosterone, the C rats showed similar plasma corticosterone levels. In the D15 rats, levels of corticosterone in the light phase one hour after ACTH administration were higher than in the dark phase; being lower than C in this phase. The loss of capacity to respond during the dark phase may be due to adrenal blunting in this phase with high levels of plasma corticosterone. In D30 rats, there is a more noticeable loss of capacity for adrenal response in the light than in the dark phase, with values lower than C and D15 rats in both phases. These findings suggest that the duration of diabetes has a significant role in both plasma corticosterone rhythms and adrenal sensitivity to ACTH administration.

Jail inmates and HIV care: provision of antiretroviral therapy and Pneumocystis carinii pneumonia prophylaxis.

The objective of this study was to examine prescription and acceptance of antiretroviral therapy (ART) and Pneumocystis carinii pneumonia (PCP) prophylaxis in jail and at release. A retrospective cross sectional design was used, by record review, of 77 inmates receiving HIV-related care in the San Francisco City and County Jail and released to the community in 1997. Average CD4 cell count was 335/microl. Fifteen had undectable HIV RNA, and average viral load was 19,826 copies/ml. Fifty-eight per cent were put on ART in jail. Lower CD4 cell count was associated with ART (P=0.017). All inmates with CD4 cell counts less than 200/microl received PCP prophylaxis. According to 1996 guidelines, 72% of those eligible for ART were on therapy. Of 24 inmates released on ART, 71% followed medical advice and picked up medication at release. HIV care in the San Francisco Jail met high standards and exceeded levels reported in other populations.

[Trans-Kehr postoperative cholangiography in upright and horizontal positions: the morphofunctional aspects of the biliary tract]. / La colangiografía postoperatoria trans Kehr en posiciones orto y horizontal: aspectos morfológico-funcionales de las vías biliares.

To change from the lying position to the upright position, in patients without their gallbladder, causes: a) a rapid and partial emptying of the biliary ducts towards the duodenum by the amplification of the opening phasic waves activity of the sphincter of Oddi (S. O.); b) an important reduction caliber of the main biliary duct (M. B. D) and c) stability of the intraductal pressure with slight raising in upright position. These physiological concepts allow a better cholangiographic exploration by means of a drip of 60 to 70 drops per minute of diluted tri-iodic in: 1) Upright position, which gives a good image regarding the terminal choledochus; of the biliary duodenal flow, and of the reduction of the caliber of the MBD. 2) In lying down position which allows: the filling up of the complete biliary-tree with possible scarcity of information about the distal choledochus-duct; the appreciation of the degree of the expansion of the MBD, and the measuring of the delay of the emptying out of the X-ray-opaque substance in relation to what was found in the upright position. The elasticity of the walls of the biliary ducts acts efficiently in the compliance of the container and contained. In normal choledochal ducts, the top level images in the upright position do not go beyond the hepatic duct. When there are problems with the flow through the S. O., there is a filling up of the intrahepatic biliary ducts with the contrast substance introduced in the upright position.

[Prevalence of Down's syndrome in Asturias, 1987-1993. Members of the Work Group of the RCDA]. / Prevalencia del síndrome de Down en Asturias, 1987-1993. Miembros del grupo de Trabajo del RDCA.

OBJECTIVE: To determine the frequency of Down Syndrome (DS) in Asturias and the prenatal diagnosis impact on the birth prevalence of this chromosomal anomaly. METHODS: The analysed data came from the Registry of Congenital Defects of Asturias (1990-1993) and from a retrospective study conducted by the same working group (1987-1989). The total prevalence rates and the prevalence at birth were calculated. RESULTS: Out of 55,601 births, DS was recorded in 83 cases: 69 livebirths, two fetal deaths and 12 induced abortions following prenatal diagnosis, giving a total prevalence rate of 14.9 per 10,000 and a birth prevalence of 12.8. The proportion of induced abortions was 15 per cent in this period; the proportion of cases in the high risk maternal age group (35 years and over) was around 50% of the total. The proportion of induced abortions was 15 per cent in this period. CONCLUSIONS: The frequency of DS in Asturias is comparable to the other populations. Prenatal diagnosis had little impact on the birth prevalence figures. These results may help us draw up prevention and prenatal diagnosis policies for these defects in Asturias when giving the frequency of this health problem.

[Primary suprarenal insufficiency and multiglandular atrophy in a patient affected by myotonic dystrophy]. / Insuficiencia suprarrenal primaria y atrofia pluriglandular en un paciente afecto de distrofia miotónica.

We present the case of a 27 year old man diagnosed as having myotonic dystrophy (MD) who showed two novelties with respect to those endocrinopathies hitherto described as being associated with MD: primary suprarenal failure and pluriglandular atrophy (thyroid and suprarenal, in addition to the already known testicular type). We describe here the results of a clonic, hormonal and genetic study of the proband and his family (a carrier father and an affected brother). We discuss the possible etiopathogenesis of the picture which, in our opinion, could consist of an abnormality of the AMPc dependent protein-kinase, related to the MD gene (PKMD). Consequently intracellular signaling was altered after the union of peptide hormones (in our case ACTH, LH and TSH) to their receptor leading, through the lack of trophic stimulus, to glandular atrophy. We conclude that before diagnosing MD, it is convenient to add suprarenal study to the traditional evaluations of possible associated endocrinopathies.
