Abstract
BACKGROUND Antidepressant drug consumption has increased, mainly in the elderly. This trend could be explained by the use for indications other than depression. We aimed to describe the indications related to antidepressant drug new users in two primary care settings. METHODS A longitudinal study of new antidepressant users aged ≥65 was conducted, with data from the Nivel-PCD (The Netherlands) and SIDIAP (Catalonia) databases (2010-2015). As a proxy for indication, diagnoses registered around the 3 months of antidepressant prescribing were collected. Indications were classified in seven categories and an additional one of non-selected indications. The percentage and incidence calculated over the total population registered was described. RESULTS A total of 16,537 and 199,168 new antidepressant users were identified in the Nivel-PCD and SIDIAP databases, respectively (women aged 65-69 were the most prevalent). Depression was the most frequent indication (24.0% and 31.3%), followed by anxiety (12.5% and 19.5%) and sleep disorders (10.2% and 26.4%). Tricyclic antidepressants were the most commonly prescribed in Nivel-PCD (48.7%), mainly associated with neuropathic pain, and selective serotonin reuptake inhibitor antidepressants in SIDIAP (63.1%), associated with depression. The non-selected indications category showed an upward trend in the Nivel-PCD database while in the SIDIAP database it decreased. LIMITATIONS It is not mandatory for physicians to register a diagnosis with each prescription. CONCLUSIONS Depression was the most common prescribing indication in The Netherlands and Spain, followed by anxiety and sleep disorders. The most commonly prescribed antidepressant differed between the countries and is likely explained by differences in local guidelines.

Abstract
Agranulocytosis is a rare yet severe idiosyncratic adverse drug reaction to metamizole, an analgesic widely used in countries such as Switzerland and Germany. Notably, an underlying mechanism has not yet been fully elucidated and no predictive factors are known to identify at-risk patients. With the aim to identify genetic susceptibility variants to metamizole-induced agranulocytosis (MIA) and neutropenia (MIN), we conducted a retrospective multi-center collaboration including cases and controls from three European populations. Association analyses were performed using genome-wide genotyping data from a Swiss cohort (45 cases, 191 controls) followed by replication in two independent European cohorts (41 cases, 273 controls) and a joint discovery meta-analysis. No genome-wide significant associations (p < 1 × 10−7) were observed in the Swiss cohort or in the joint meta-analysis, and no candidate genes suggesting an immune-mediated mechanism were identified. In the joint meta-analysis of MIA cases across all cohorts, two candidate loci on chromosome 9 were identified, rs55898176 (OR = 4.01, 95%CI: 2.41–6.68, p = 1.01 × 10−7) and rs4427239 (OR = 5.47, 95%CI: 2.81–10.65, p = 5.75 × 10−7), of which the latter is located in the SVEP1 gene previously implicated in hematopoiesis. This first genome-wide association study for MIA identified suggestive associations with biological plausibility that may be used as a stepping-stone for post-GWAS analyses to gain further insight into the mechanism underlying MIA.

Abstract
Background and Objective: Agranulocytosis is a rare and potentially life-threatening complication of metamizole (dipyrone) intake that is characterized by a loss of circulating neutrophil granulocytes. While the mechanism underlying this adverse drug reaction is not well understood, involvement of the immune system has been suggested. In addition, associations between genetic variants in the Human Leukocyte Antigen (HLA) region and agranulocytosis induced by other drugs have been reported. The aim of the present study was to assess whether genetic variants in classical HLA genes are associated with the susceptibility to metamizole-induced agranulocytosis (MIA) in a European population by targeted resequencing of eight HLA genes. Design: A case-control cohort of Swiss patients with a history of neutropenia or agranulocytosis associated with metamizole exposure (n = 53), metamizole-tolerant (n = 39) and unexposed controls (n = 161) was recruited for this study. A high-throughput resequencing (HTS) and high-resolution typing method was used to sequence and analyze eight HLA loci in a discovery subset of this cohort (n = 31 cases, n = 38 controls). Identified candidate alleles were investigated in the full Swiss cohort as well as in two independent cohorts from Germany and Spain using HLA imputation from genome-wide SNP array data. In addition, variant calling based on HTS data was performed in the discovery subset for the class I genes HLA-A, -B, and -C using the HLA-specific mapper hla-mapper. Results: Eight candidate alleles (p < 0.05) were identified in the discovery subset, of which HLA-C∗04:01 was associated with MIA in the full Swiss cohort (p < 0.01) restricted to agranulocytosis (ANC < 0.5 × 109/L) cases. However, no candidate allele showed a consistent association in the Swiss, German and Spanish cohorts. Analysis of individual sequence variants in class I genes produced consistent results with HLA typing but did not reveal additional small nucleotide variants associated with MIA. Conclusion: Our results do not support an HLA-restricted T cell-mediated immune mechanism for MIA. However, we established an efficient high-resolution (three-field) eight-locus HTS HLA resequencing method to interrogate the HLA region and demonstrated the feasibility of its application to pharmacogenetic studies.

Abstract
Agranulocytosis is a serious, although rare, adverse reaction to sulfasalazine, which is used to treat inflammatory joint and bowel disease. We performed a genome-wide association study comprising 9,380,034 polymorphisms and 180 HLA alleles in 36 cases of sulfasalazine-induced agranulocytosis and 5,170 population controls. Sulfasalazine-induced agranulocytosis was significantly associated with the HLA region on chromosome 6. The top hit (rs9266634) was located close to HLA-B, odds ratio (OR) 5.36 (95% confidence interval (CI) (2.97, 9.69) P = 2.55 × 10-8 ). We HLA-sequenced a second cohort consisting of 40 cases and 142 treated controls, and confirmed significant associations with HLA-B*08:01, OR = 2.25 (95% CI (1.02, 4.97) P = 0.0439), in particular the HLA-B*08:01 haplotype HLA-DQB1*02:01-DRB1*03:01-B*08:01-C*07:01, OR = 3.79 (95% CI (1.63, 8.80) P = 0.0019), and with HLA-A*31:01, OR = 4.81 (95% CI (1.52, 15.26) P = 0.0077). The number needed to test for HLA-B*08:01 and HLA-A*31:01 to avoid one case was estimated to be 1,500. We suggest that intensified monitoring or alternative treatment should be considered for known carriers of HLA-B*08:01 or HLA-A*31:01.

Abstract
OBJECTIVE Macrophages are known to be involved in low-grade inflammatory processes such as obesity. soluble cluster of differentiation 163 (sCD163) is shed from the cell surface as specific macrophage activation marker. In prepubertal children, we studied if circulating sCD163 is associated with metabolic and cardiovascular risk markers. METHODS A population of 236 school-aged Caucasian children (111 girls and 125 boys) aged 8 ± 1 year [81 normal weight (body mass index [BMI]-SDS < 1); 74 overweight (1 ≤ BMI-standard deviation score [SDS] < 2) and 81 with obesity (BMI-SDS ≥ 2)] were studied. BMI, waist circumference, fat mass and visceral fat were measured. Fasting serum sCD163, homeostatic model assessment of insulin resistance, high sensitivity C-reactive protein, gamma-glutamyl transpeptidase and lipids were quantified. RESULTS Circulating sCD163 concentrations were higher in children with obesity (p < 0.0001). Associations were observed between circulating sCD163 and a less favourable metabolic profile as judged by higher waist circumference, fat mass, visceral fat, epicardial fat, homeostatic model assessment of insulin resistance, high sensitivity C-reactive protein, gamma-glutamyl transpeptidase and triglycerides (all between r = 0.173 and r = 0.363; p < 0.05 to p < 0.0001) and lower high-density lipoprotein-cholesterol (r = -0.285, p < 0.0001). In multiple regression analyses, circulating sCD163 was independently associated with HOMA-IR (β = 0.162, p = 0.016; model R2 = 0.179) and high density lipoprotein-cholesterol/triglycerides ratio (β = -0.167, p = 0.012; model R2 = 0.209). CONCLUSIONS Childhood obesity may increase the risk of developing metabolic diseases later in life through chronic macrophage activation having deleterious effects on metabolism.

Abstract
BACKGROUND Drug-induced agranulocytosis is a potentially life-threatening adverse reaction. Genome-wide association studies (GWASs) in ethnic Chinese people in Taiwan and Hong Kong have shown an association between agranulocytosis induced by antithyroid drugs and the HLA alleles HLA-B*38:02 and HLA-DRB1*08:03. We aimed to identify genetic variants associated with antithyroid drug-induced agranulocytosis in a white European population. METHODS We did a GWAS in 234 European adults with any non-chemotherapy drug-induced agranulocytosis (absolute neutrophil count ≤0·5 × 10(9)/L [≤500/μL]) and 5170 population controls. 39 of the 234 patients had agranulocytosis that was induced by antithyroid drugs (thiamazole [methimazole], carbimazole, or propylthiouracil). After imputation and HLA allele prediction, 9 380 034 single nucleotide polymorphisms (SNPs) and 180 HLA alleles were tested for association. The genome-wide significance threshold was p<5 × 10(-8). FINDINGS Agranulocytosis induced by non-chemotherapy drugs in general was significantly associated with the HLA region on chromosome 6, with odds ratios (ORs) of 3·24 (95% CI 2·31-4·55, p=1·20 × 10(-11)) for HLA-B*27:05 and 3·57 (2·61-4·90, p=2·32 × 10(-15)) for the top SNP (rs114291795). Drug-specific analysis showed that the association with HLA-B*27:05 was largely driven by cases induced by antithyroid drugs. In a multiple logistic regression model, the OR for HLA-B*27:05 was 7·30 (3·81-13·96) when antithyroid drug-induced agranulocytosis was compared with population controls (p=1·91 × 10(-9)) and 16·91 (3·44-83·17) when compared with a small group of hyperthyroid controls (p=5·04 × 10(-4)). Three SNPs were strongly associated with antithyroid drug-induced agranulocytosis: rs652888 (OR 4·73, 95% CI 3·00-7·44, p=1·92 × 10(-11)) and rs199564443 (17·42, 7·38-41·12, p=7·04 × 10(-11)), which were independent of HLA-B*27:05, and rs1071816 (5·27, 3·06-9·10, p=2·35 × 10(-9)) which was in moderate linkage disequilibrium with HLA-B*27:05. In heterozygous carriers of all three SNPs, the predicted probability of antithyroid drug-induced agranulocytosis was about 30% (OR 753, 95% CI 105-6812). To avoid one case of agranulocytosis, based on the possible risk reduction if all three SNPs are genotyped and carriers are treated or monitored differently from non-carriers, roughly 238 patients would need to be genotyped. INTERPRETATION In white European people, antithyroid drug-induced agranulocytosis was associated with HLA-B*27:05 and with other SNPs on chromosome 6. In the future, carriers of these variants could be placed under intensified monitoring or offered alternative treatment for hyperthyroidism.

Abstract
OBJECTIVE To determine the frequency of mutant alleles in the CYP21 gene in Spanish girls presenting with precocious pubarche (PP) and to assess the relationships between genotype and endocrine-metabolic variables. DESIGN Fifty-three unrelated girls with a history of PP (14 prepubertal, 8 pubertal and 31 postmenarcheal) and 35 controls were studied. METHODS Genomic DNA was extracted from peripheral blood leukocytes. After selection against the pseudogen, an allele-specific PCR was used to identify 14 known mutations in the CYP21 gene. The mutations studied were Pro30Leu, splice intron 2, Ilel72Asn, Cluster E(6), Glyl92Ser, Ins T, GT-CT, Gln318-stop, Arg357Trp, Trp406-stop, Pro453Ser, Arg483Pro, Arg483 frameshift and Val281Leu. A standard 2-h oral glucose tolerance test was performed in all PP girls. Ovarian 17-hydroxyprogesterone (17-OHP) responses to gonadotrophin-releasing hormone-agonist stimulation was assessed in postmenarcheal PP girls. RESULTS Thirteen PP girls and eight control girls were heterozygous for one of the mutations studied. The frequency of the carrier status was 25% and 23% in the PP and control groups respectively. Severe mutations were found in 33% of the carrier girls. Serum 17-OHP responses to ACTH stimulation were similar in carriers and non-carriers (351+/-65 vs 334+/-22 ng/dl). The presence of ovarian hyperandrogenism and/or hyperinsulinism was also not related to the carrier status. CONCLUSION The incidence of molecular defects in the CYP21 gene in the present study was comparable in the PP and control groups. We found no relationship between the presence of carrier status and endocrine-metabolic abnormalities. Prospective studies of larger cohorts of PP girls are needed to ascertain the long-term clinical relevance of CYP21 heterozygosity.

Abstract
Orthotopic liver transplantation (OLT) offers the only chance to eliminate both tumor and liver disease in patients with hepatocellular carcinoma (HCC) and cirrhosis. However, tumor progression while on the waiting list and recurrence after OLT are frequent. We undertook a large multicenter study to assess survival and related factors of recurrence after OLT. This retrospective study analyses data from 307 consecutive patients with HCC and cirrhosis treated with OLT between 1990 and 1997 in eight centers in Spain. OLT was indicated only for small (<5 cm) localized tumors. Five-year rates after OLT were 63% for survival, 58% for disease-free survival, and 21% for recurrence. Tumor diameter larger than 5 cm was associated with other tumor characteristics that were significant indicators of poor outcome (absence of capsule, three or more nodules, bilobularity, satellite nodules, and vascular invasion). However, in multivariate analysis, alpha fetoprotein (AFP) levels greater than 300 ng/mL (P = .04; P = .02) and macroscopic vascular invasion (P = .01; P = .0001) were the only factors independently associated with mortality and recurrence, respectively. OLT is indicated in patients with small HCCs who have low AFP levels and no macroscopic vascular invasion or extrahepatic disease. By increasing our ability for preoperative tumor imaging, we will achieve better selection of patients with HCC before OLT.

Abstract
BACKGROUND The urgent need to increase the organ donor pool has led to the expansion of criteria for donor selection. The aim of this study was to analyze the influence of donor age on early graft function, subsequent graft loss, and mortality after liver transplantation (LT). METHODS Data on LT were evaluated retrospectively in a population-based cohort of 400 LTs in 348 patients. Of these, 21 (5%) were from donors >70 years old. Pretransplantation donor and recipient characteristics and the evolution of recipients were analyzed. The influence of donor age as a risk factor was assessed using univariate and multivariate analyses. RESULTS Actuarial graft survival was 89% at 1 month after LT, 81% after 6 months, and 59% after 60 months. Multivariate analysis demonstrated that only donor age (>70 years old) was associated with a higher risk of long-term graft loss (relative risk [RR]=1.4, 95% confidence interval [CI]=1-1.9; P=0.03) and mortality (RR=1.7, 95% CI=1.2-2.3; P=0.01). Graft survival of septuagenarian livers was 80% at 1 month after LT, 56% after 6 months, and 25% after 54 months. Actuarial survival analysis (Kaplan-Meier curves) also demonstrated worse evolution in recipients of livers from old donors (log-rank test, P<0.001). CONCLUSIONS Advanced donor age is associated with lower graft and recipient survival.

Abstract
OBJECTIVE Our aim was to determine whether the clinical features of 21-hydroxylase-deficient nonclassic adrenal hyperplasia are correlated with either age at symptom onset or age at presentation, or both, and with the degree of adrenocortical abnormality. STUDY DESIGN In a multicenter cohort design 220 women with nonclassic adrenal hyperplasia, with a basal or adrenocorticotropic hormone-stimulated 17-hydroxyprogesterone level >30.3 nmol/L, were studied, either prospectively (n = 39) or retrospectively (n = 181). Patients were stratified by age of presentation into 5 groups: (1) <10 years (n = 25), (2) 10 to 19 years (n = 64), (3) 20 to 29 years (n = 83), (4) 30 to 39 years (n = 30), and (5) 40 to 49 years (n = 16). Two patients >50 years old were excluded from the analysis because of age. RESULTS Ninety-two percent of patients <10 years old had premature pubarche at presentation, whereas clitoromegaly and acne were each present in only 20% of these younger subjects. With only patients > or =10 years old considered, presenting clinical features included hirsutism (59%), oligomenorrhea (54%), acne (33%), infertility (13%), clitoromegaly (10%), alopecia (8%), primary amenorrhea (4%), and premature pubarche (4%). Among the patients >/=10 years old, the prevalence but not the degree of hirsutism increased significantly with age. Basal levels of 17-hydroxyprogesterone in adolescents were significantly higher than the levels found either in children (<10 years old) or women 40 to 49 years old (P <.01 and P <.03, respectively), although no difference was noted in the stimulated 17-hydroxyprogesterone levels between age groups. The adrenocorticotropic hormone-stimulated levels but not the basal levels of 17-hydroxyprogesterone were significantly higher in patients with clitoromegaly than in women without clitoromegaly. Alternatively, there were no differences in either basal or stimulated 17-hydroxyprogesterone levels between patients with and those without hirsutism, acne, or alopecia. CONCLUSION In children <10 years old the most common presenting complaint was premature pubarche, whereas hirsutism and oligomenorrhea were more common in older patients. The prevalence of hirsutism increased with age, suggesting the progressive nature of nonclassic adrenal hyperplasia. Furthermore, the adrenocorticotropic hormone-stimulated levels of 17-hydroxyprogesterone were higher in patients with clitoromegaly, which suggests that the degree of adrenocortical dysfunction in nonclassic adrenal hyperplasia determines, at least in part, the clinical presentation.

Abstract
BACKGROUND/AIM The extent of gastric resection and the role of lymphadenectomy in the treatment of gastric cancer are controversial. METHODS This study evaluates the results of radical gastric resection (D2 lymphadenectomy) in 375 patients with a gastric carcinoma operated according to a prospective protocol. RESULTS Total gastrectomy was performed in 196 and a subtotal gastrectomy in 179 patients, with an operative mortality of 3.5 and 2.8%. The presence of lymph node metastasis was related to the depth of the tumor in the gastric wall. The cumulative 5-year survival was dependent on the depth of tumoral invasion in the gastric wall and also on the presence of lymphatic metastasis. Curative resection had a significantly better 5-year survival (72%) than noncurative resection (26%). CONCLUSION Although it is difficult to prove the benefits of extended lymphadenectomy in the surgical treatment of gastric carcinoma, the results of these series seem to support its usefulness.

Abstract
Using a simple and standardized method we estimated both insulin secretion and insulin sensitivity in peripheral tissues in relation to Tanner pubertal stages. Early insulin response, mean blood glucose (MBG), mean serum insulin (MSI), glucose uptake rate in peripheral tissues and insulin sensitivity index (SI) in response to the standard oral glucose tolerance test were evaluated in 73 normal girls. Study subjects were divided into 4 groups: group 1 (Tanner stage I, n = 20); group 2 (Tanner stage II, n = 14); group 3 (Tanner stages III and IV, n = 15), and group 4 (Tanner stage V, n = 24). Steroid levels and insulin-like growth factors were determined to characterize clinical pubertal development. MBG was similar in all groups but MSI increased at stage II and retained similar values throughout puberty, with those of group I being statistically lower than in the other groups (p < 0.001). When MSI values were adjusted per kilogram of body weight, a significant increase was observed in group II (p < 0.05). The MSI adjusted values were: group 1, 1.0 +/- 0.4; group 2, 1.4 +/- 0.4; group 3, 1.0 +/- 0.3, and group 4, 1.0 +/- 0.4 mU/l/kg. SI values were similar in groups 1 and 2 and significantly lower than in groups 3 and 4 (p < 0.001). Our results confirm both that insulin secretion is related to age and that an insulin-resistant state occurs during puberty. Thus, the insulin-resistant state coincides with Tanner stage II. In conclusion, this mathematical approach is considered to be a simple and reliable method for analyzing the possible alterations in insulin secretion and action in children and adolescents in whom more sophisticated procedures must be limited in this early period of life for ethical reasons.

Abstract
Cumulative recurrence after surgical resection for hepatocellular carcinoma (HCC) is very high. Several retrospective analyses have shown that liver transplantation was more effective than resection for patients with HCC at early tumor stages. Consequently, in January 1990, we decided to prospectively indicate orthotopic liver transplantation (OLT) as the first surgical treatment for small, localized HCC in cirrhotic patients without nodal involvement independently of the degree of liver function. The aim of this prospective cohort study was to analyze prognosis, recurrence rate, and survival after liver transplantation in patients in whom the main indication was HCC with cirrhosis. Thirty-eight patients in whom the main indication for liver transplantation was HCC and hepatic cirrhosis were compared with 136 transplantations because of cirrhosis without tumor, performed in our unit from January 1990 to December 1995. HCC arising in noncirrhotic livers and those incidently discovered after OLT were excluded from the study. Chemoembolization using doxorubicin, lipiodol, and Gelfoam was performed before OLT in 31 patients with good liver function. There were no differences in gender, but HCC patients were older (57 +/- 7 vs. 50 +/- 10 years [P < .001]). Liver function was better in HCC (Child-Pugh score: 6.9 +/- 2 vs. 8.6 +/- 1.8; P < .001), and hepatitis C virus antibody was positive in 31 (82%) vs. 51 (37%) (P < .007). Seven tumors had bilobar involvement (18%). Capsule was present in 22 (58%). The mean size of the tumor was 3.4 +/- 2 cm. Seventeen tumors (45%) were larger than 3 cm, and 4 (11%) were larger than 5 cm. The average number of nodules was 2 +/- 1. The tumor-node-metastasis stage of the tumors was pT1 in 6 patients (16%), 11 were pT2 (29%), 12 were pT3 (31%), and 9 were pT4 (24%). Seven patients were retransplanted in the HCC group (18%) and 19 (14%) in the nontumor group (not significant). Tumor recurrence was detected in three patients (8%). One, 3-, and 5-year survival rates were 82% vs. 79%, 75% vs. 71%, and 63% vs. 68%, respectively, for patients with and without HCC, and no differences were found between the two groups (P = .84). Survival was significantly reduced in patients with a macroscopic vascular invasion and tumors greater than 5 cm in diameter. Recurrence and mortality after liver transplantation in cirrhotic patients with carefully selected HCC are similar to the results in cirrhotic patients without tumor.

Abstract
Women with polycystic ovary syndrome (PCOS: hyperandrogenism and oligomenorrhea) have been shown to have exaggerated ovarian 17-hydroxyprogesterone (17-OHP) responses after GnRH agonist stimulation, suggestive of disordered ovarian cytochrome P450c17 alpha activity. However, most hyperandrogenic women also have an exaggerated LH response to both native GnRH and GnRH agonists. To assess whether the known LH hyperresponsiveness in PCOS patients mediates their exaggerated 17-OHP response to GnRH agonist challenge or whether the 17-OHP response can be duplicated by direct stimulation of the ovary with a fixed amount of hCG, 25 PCOS women [age, 20.6 +/- 1.1 yr; body mass index (BMI), 24.9 +/- 1.3 kg/m2] and 5 controls (age, 29.4 +/- 2.3 yr; BMI, 29.2 +/- 3.0) underwent both GnRH agonist (leuprolide acetate) and hCG testing. In addition, 23 normal women (age, 26.5 +/- 1.5 yr; BMI, 27.2 +/- 1.7 kg/m2) underwent hCG testing, and 21 other normal women (age, 19.3 +/- 0.5 yr; BMI, 23.0 +/- 0.8 kg/m2) underwent leuprolide acetate challenge. Blood was sampled before and 24 h after (the previously determined time of the peak response) leuprolide acetate (500 micrograms, sc) and hCG (5000 IU, im) stimulation tests. The tests were administered during the early follicular phase in women who were ovulatory and in randomized order in the subjects receiving both stimuli. Peak serum 17-OHP levels did not differ between leuprolide acetate or hCG stimulation in PCOS patients or controls when measured at 24 h (324.9 +/- 41.9 vs. 360.4 +/- 54.0 in PCOS; 183.2 +/- 19.6 vs. 141.2 +/- 11 ng/dL in controls). Peak 17-OHP levels after hCG challenge and GnRH agonist stimulation were highly correlated (r = 0.82; P < 0.001) in the subjects receiving both stimuli. Although leuprolide acetate elicited a higher estradiol (E2) response than hCG in all subjects, serum E2 levels increased significantly after hCG treatment in both patients and controls (P < 0.001 and P < 0.0001). The small, but significant, increase in serum E2 after hCG stimulation suggests that a rigid two-cell model of ovarian steroidogenesis may be an oversimplification of in vivo physiology. Our results suggest that exaggerated 17-OHP responses to GnRH agonist stimulation in hyperandrogenic women are not mediated by the known hyperresponsiveness of LH in these patients, but are due to increased ovarian androgen sensitivity to LH stimulation.

Abstract
To assess whether patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency exhibit a steroidogenic response to GnRH agonist consistent with functional ovarian hyperandrogenism (FOH) and elucidate the relationship between adrenal and ovarian hyperandrogenism, the LH, FSH, estradiol, 17-hydroxyprogesterone (17-OHP), androstenedione, total testosterone, dehydroepiandrosterone, and 17-hydroxypregnenolone responses to a sc dose of leuprolide acetate (500 micrograms) were evaluated in 10 patients with classic CAH (mean age, 18.4 +/- 0.95 yr), 7 of whom had oligomenorrhea, pretreated with dexamethasone (2 mg/day for 5 days, including the day of the test). The results were compared with those obtained in 11 patients with FOH (mean age, 18.7 +/- 0.46 yr) and 17 normal women (mean age, 19.68 +/- 0.59 yr) not pretreated with dexamethasone. Leuprolide acetate stimulation caused a significant augmentation of plasma E2, 17-OHP, androstenedione, testosterone, and 17-hydroxypregnenolone concentrations in all CAH patients. However, in only 6 (60%) of them, all with oligomenorrhea, was the 17-OHP response (posttest minus pretest value) similar to that of FOH patients and significantly higher than that in controls. In this subset of CAH patients, LH plasma levels after stimulation were significantly higher than those of CAH subjects with 17-OHP responses in the normal range, controls, and FOH patients, whereas FSH levels were similar to those of controls. In this latter group, plasma FSH concentrations after stimulation were significantly higher than those in FOH. In conclusion, the results of the present study indicate that LH-dependent functional ovarian hyperandrogenism is frequent in patients with classic CAH. As ovarian hyperandrogenism might be partially responsible for the menstrual irregularities that are common complications in such patients, all classic CAH patients with oligomenorrhea should undergo short term stimulation with GnRH agonists to ascertain the presence of ovarian hyperandrogenism and receive appropriate treatment.

Abstract
The postpubertal outcome of a group of girls diagnosed of premature pubarche during childhood was assessed 1) to determine the incidence of functional ovarian hyperandrogenism (FOH) through the ovarian-steroidogenic response to the GnRH agonist leuprolide acetate, 2) to validate leuprolide acetate stimulation in FOH diagnosis, and 3) to ascertain whether FOH-predictive biochemical markers exist at the diagnosis of premature pubarche. Of 35 patients (age, 15.4 +/- 1.5 yr), 16 showed hirsutism, oligomenorrhea, and elevated baseline testosterone and/or androstenedione (delta 4-A) levels. Subcutaneous administration of leuprolide acetate (500 micrograms) produced similar increases in gonadotropin levels in oligomenorrheic patients, regularly menstruating patients (n = 19), and controls (n = 12; age, 15.3 +/- 1.3 yr) when tested at 6 h. Of all of the steroids measured, 17-hydroxyprogesterone (17-OHP) and delta 4-A levels 24 h postleuprolide acetate stimulation were significantly higher in oligomenorrheic patients than in the other two groups (P < 0.0001). No overlapping in 17-OHP responses occurred between oligomenorrheic patients and the other groups. Baseline dehydroepiandrosterone sulfate and delta 4-A levels at the diagnosis of premature pubarche correlated with 17-OHP values postleuprolide acetate challenge (r = 0.47; P < 0.005 and r = 0.67; P < 0.0001, respectively). These results show a distinct leuprolide acetate challenge response in 45% of the postpubertal premature pubarche girls studied, suggestive of an increased incidence of FOH, and support the need for continued routine postmenarcheal evaluation of this group of patients. Responses of 17-OHP to leuprolide acetate challenge facilitate the identification of FOH patients, establish this test as a reliable diagnostic tool in FOH diagnosis, and confirm the ovaries as the source of hyperandrogenemia in most patients with androgen excess. Although increased 17-OHP responses after leuprolide acetate stimulation seem to occur more frequently in girls with elevated dehydroepiandrosterone sulfate and/or delta 4-A levels at the diagnosis of premature pubarche, specific biochemical markers predictive of FOH in this group of patients are still lacking.

Abstract
The natural history of girls with premature pubarche is reported to be normal, but the effects on puberty and on final height are not well documented. We assessed the outcome of a group of girls with premature pubarche from two Latin populations in whom 21-hydroxylase deficiency had been ruled out by an ACTH test. Patients comprised 127 girls (70 Northern-Italian and 57 Northern-Spanish), of whom 69 had entered puberty and 38 had attained adult height. Height, bone age, onset and progression of puberty, height prognosis, adult height, and baseline plasma androgen levels were evaluated. Advanced skeletal maturation and tall stature were constant features during the first years of follow-up and subsequently declined. Puberty began at 9.7 +/- 0.9 yr, and age at menarche (12.0 +/- 1.0 yr) was comparable to maternal and population menarcheal ages. The appearance and chronology of pubertal milestones in both populations were very similar. Adult heights correlated with the height prognosis at diagnosis and at onset of puberty, and were above midparental heights. Premature pubarche produces a transient acceleration in growth and bone maturation with no negative effects on the onset and progression of puberty and final height.

Abstract
Over a year period, 60 of 172 patients presenting with upper gastrointestinal bleeding were treated by endoscopic thermocoagulation. Entry criteria included active bleeding (pulsatile or oozing), a visible vessel, sentinel clot or the presence of a pigmented protuberance at the ulcer crater. Hemostatic therapy was performed using the heat probe. The physical status and risk of the patients was estimated according to the ASA classification. Hemostasis was obtained in 17 of 21 patients with pulsatile bleeding (81%), 30 of 30 patients with oozing (100%) and 18 of 18 patients with a visible vessel or a pigmented protuberance in the lesion (100%). Three patients, older than 70 years of age, died. All had pulsatile bleeding from a deep ulcer located at the posterior-inferior wall of the duodenal bulb. They were classified as ASA III (n = 1) or IV (n = 2) with significant concomitant illness. These results suggest that endoscopic thermocoagulation is an effective treatment of active upper gastrointestinal bleeding, especially useful in a group of high risk patients.

Abstract
Overexpression of the Multiple Drug Resistance gene (MDR1) has been proposed as a major mechanism related to both intrinsic and acquired resistance to chemotherapeutic agents. The gene product is a membrane protein (P-glycoprotein), that acts as an energy-dependent drug efflux pump decreasing drug accumulation in resistant tumor cells. We have characterized MDR1 and P-Glycoprotein expression in human gastric adenocarcinoma and in precursor lesions. MDR1 mRNAs, analyzed by dot-blot technique, were detected in 9 of 10 non-tumoral gastric mucosae and in 8 of 10 gastric adenocarcinomas. Immunohistochemical analysis, using the MRK16 monoclonal antibody, revealed heterogeneous expression of P-Glycoprotein in individual cells. The P-Glycoprotein was found on the surface of cells of gastric areas with intestinal metaplasia subtype III. This type of intestinal metaplasia, also called "colonic metaplasia", has been strongly associated with a high risk for the development of gastric cancer. The fact that the P-Glycoprotein was detected in this precursor lesion is consistent with the intestinal metaplasia-dysplasia and carcinoma sequence proposed in the histogenesis of this tumour. The finding that P-Glycoprotein was heterogeneously expressed in malignant cells of some gastric adenocarcinomas also suggests that this transporter system probably contributes to primary and secondary multidrug resistance in this neoplasm.

Abstract
As a result of the lack of an adequate regulation, the supply and the use of medicines is irrational in Spain. In order to know the characteristics of the prescription and use of drugs among the elderly, two drug utilization studies were carried out. The first study was an analysis of 981 prescriptions from an outpatient clinic of the Spanish Social Security. The results show that a high proportion of fixed-dose combinations were prescribed and that drugs without any demonstrated therapeutic value are often prescribed for the elderly. The second study was a survey of 389 individuals randomly chosen among people affiliated with a pensioners' club. The results show that drug use is highly prevalent among the elderly, that many medicines without any demonstrated benefit are being taken, and that potentially harmful drugs were being used by a high proportion of patients without medical follow-up. The prevalence of the use of some particular groups of drugs is also presented.
