Abstract
Background Congenital disorders of glycosylation (CDG) are a growing group of rare genetic disorders. The most common CDG is phosphomannomutase 2 (PMM2)-CDG which often has a severe clinical presentation and life-limiting consequences. There are no approved therapies for this condition. Also, there are no validated disease-specific quality of life (QoL) scales to assess the heterogeneous clinical burden of PMM2-CDG which presents a challenge for the assessment of the disease severity and the impact of a certain treatment on the course of the disease. Aim and methods This study aimed to identify the most impactful clinical signs and symptoms of PMM2-CDG, and specific patient and observer reported outcome measures (PROMs and ObsROMs, respectively) that can adequately measure such impact on patients’ QoL. The most burdensome signs and symptoms were identified through input from the CDG community using a survey targeting PMM2-CDG families and experts, followed by family interviews to understand the real burden of these symptoms in daily life. The list of signs and symptoms was then verified and refined by patient representatives and medical experts in the field. Finally, a literature search for PROMs and ObsROMs used in other rare or common diseases with similar signs and symptoms to those of PMM2-CDG was performed. Results Twenty-four signs/symptoms were identified as the most impactful throughout PMM2-CDG patients’ lifetime. We found 239 articles that included tools to measure those community-selected PMM2-CDG symptoms. Among them, we identified 80 QoL scales that address those signs and symptoms and, subsequently, their psychometric quality was analysed. These scales could be applied directly to the PMM2-CDG population or adapted to create the first PMM2-CDG-specific QoL questionnaire. Conclusion Identifying the impactful clinical manifestations of PMM2-CDG, along with the collection of PROMs/ObsROMs assessing QoL using a creative and community-centric methodology are the first step towards the development of a new, tailored, and specific PMM2-CDG QoL questionnaire. These findings can be used to fill a gap in PMM2-CDG clinical development. Importantly, this methodology is transferable to other CDG and rare diseases with multiple signs and symptoms.

Abstract
Dehydration of the edible seaweed Chondrus crispus was performed by freeze-drying, conventional oven-drying and emerging microwave hydrodiffusion and gravity (MHG). In this work, the drying kinetics and modelling, estimating specific energy consumption and environmental impact of distinct processes were tested. Color and microstructural features of the dried macroalgae were also evaluated, as well as their nutritive characterization, chemical profile and bioactive potential (antioxidant and antimicrobial activities). Moreover, collected liquid phases from both the defrosted and MHG treated samples were also characterized. All methodologies provided solid phases with an adequate final moisture content. MHG significantly reduced the needed time, specific energy consumption and environmental impact, providing C. crispus with intermediate color and histological structure characteristics. Overall, this trend was also defined to tested chemical parameters and bioactivities. MHG provided aqueous extracts with potential bioactive compounds from this red alga, increasing the efficiency of this drying method.

Abstract
Background The aim of this in vitro study was to evaluate the influence of the cortical thickness on the primary stability of short and conventional-sized implants with two types of prosthetic connection.
Material and Methods Seventy-two implants were used. These implants were placed in polyurethane blocks that simulated low-density bone tissue (type IV bone), with two bone cortical heights (type I bone): 1mm and 3mm. The implants were divided into 6 groups with 12 implants each according to the type of prosthetic connections (external-hexagon -EH and morse taper- MT) and implant sizes (conventional- 4x10mm and short 5x5mm; 5.5x5mm; 5x6mm; 5.5x6mm). Insertion torque (IT) and resonance frequency analyzes (RFA) were performed to evaluate the primary stability of the implants.
Results All implants installed in blocks with 3mm of cortical thickness showed greater IT than those installed in 1mm. The short-sized MT implants had a higher IT than conventional implants of the same connection. Short-sized EH implants showed less IT than short-sized MT implants in blocks with 3mm of cortical. In blocks with 1mm of cortical, conventional EH implants had a higher IT compared to short-sized EH implants. The conventional sized implants presented higher RFA values despite the thickness of the cortical in the blocks.
Conclusions The greater bone cortical thickness and implants size provides greater primary stability of the implants regardless the prosthetic connection. Key words:Implants connection, implants macrostructure, primary stability.

Abstract
Prostate cancer (PCa) is one of the most common cancers in men, with a huge impact on their health. The use of Castanea sativa Mill. flowers (CFs) in beverages has been reported, through ancestral claims, as having health benefits. In vitro research has evidenced the properties of CFs, such as antitumor and antioxidant activities. This study aimed to evaluate the effects of CF extract in an animal model of PCa. Forty male Wistar Unilever rats were randomly assigned to four groups: control, induced, control + CF, and induced + CF groups. Animals from the induced groups were exposed to a multistep protocol for PCa induction. The CF extract, rich in trigalloyl-HHDP-glucoside and obtained via decoction, was administered to the CF groups in drinking water (3 mg per animal per day) for 49 weeks. Animals were sacrificed at 61 weeks of age. Regarding the effects of CFs on dorsolateral prostate tumorigenesis, no significant differences were observed between the induced and induced + CF groups. However, animals exposed to the CF extract showed fewer inflammation areas on the dorsolateral prostate lobe than those not exposed to CF. Moreover, the CF extract alleviated the hepatic oxidative stress associated with the multistep protocol, resulting in lower levels of lipid peroxidation. These results suggest that CF extract has antioxidant and anti-inflammatory properties.

Abstract
Arbutus unedo L. (strawberry tree) has showed considerable content in phenolic compounds, especially flavan-3-ols (catechin, gallocatechin, among others). The interest of flavan-3-ols has increased due their bioactive actions, namely antioxidant and antimicrobial activities, and by association of their consumption to diverse health benefits including the prevention of obesity, cardiovascular diseases or cancer. These compounds, mainly catechin, have been showed potential for use as natural preservative in foodstuffs; however, their degradation is increased by pH and temperature of processing and storage, which can limit their use by food industry. To model the degradation kinetics of these compounds under different conditions of storage, three kinds of machine learning models were developed: i) random forest, ii) support vector machine and iii) artificial neural network. The selected models can be used to track the kinetics of the different compounds and properties under study without the prior knowledge requirement of the reaction system.

Abstract
Melissa officinalis is a plant from the family Lamiaceae, native in Europe particularly in the Mediterranean region. Given our interest in identifying extracts and compounds capable of inhibiting tumor cell growth, and given the antioxidant content and the high consumption of Melissa officinalis in Portugal, this study aimed to test the tumor cell growth inhibitory activity of five different extracts of this plant (aqueous, methanolic, ethanolic, hydromethanolic and hydroethanolic) in three human tumor cell lines: MCF-7, AGS and NCI-H460. All extracts decreased cell growth in all cell lines in a concentration-dependent manner. The ethanolic extract was the most potent one, presenting a GI50 concentration of approximately 100.9 μg mL-1 in the NCI-H460 lung cancer cells. This extract was characterized by LC-DAD-ESI/MS regarding its phenolic composition, revealing rosmarinic acid as the most abundant compound. The GI75 concentration of this extract affected the cell cycle profile of these cells. In addition, both the GI50 and the GI75 concentrations of the extract induced cellular apoptosis. Moreover, treatment of NCI-H460 cells with this extract caused a decrease in pro-caspase 3 and an increase in p53 levels. This study emphasizes the relevance of the study of natural products as inhibitors of tumor cell growth.

Abstract
BACKGROUND AND AIMS Anaemia is an important complication of inflammatory bowel disease [IBD]. The aim of this study was to determine the prevalence of anaemia and the practice of anaemia screening during the first year following diagnosis, in a European prospective population-based inception cohort. METHODS Newly diagnosed IBD patients were included and followed prospectively for 1 year in 29 European and one Australian centre. Clinical data including demographics, medical therapy, surgery and blood samples were collected. Anaemia was defined according to the World Health Organization criteria. RESULTS A total of 1871 patients (Crohn's disease [CD]: 686, 88%; ulcerative colitis [UC]: 1,021, 87%; IBD unclassified [IBDU] 164. 81%) were included in the study. The prevalence of anaemia was higher in CD than in UC patients and, overall, 49% of CD and 39% of UC patients experienced at least one instance of anaemia during the first 12 months after diagnosis. UC patients with more extensive disease and those from Eastern European countries, and CD patients with penetrating disease or colonic disease location, had higher risks of anaemia. CD and UC patients in need of none or only mild anti-inflammatory treatment had a lower risk of anaemia. In a significant proportion of patients, anaemia was not assessed until several months after diagnosis, and in almost half of all cases of anaemia a thorough work-up was not performed. CONCLUSIONS Overall, 42% of patients had at least one instance of anaemia during the first year following diagnosis. Most patients were assessed for anaemia regularly; however, a full anaemia work-up was frequently neglected in this community setting.

Se estudió la calidad de la canal y la carne de lechales ovinos comerciales de raza Churra Tensina (n= 26) según la época de cría y sacrificio (primavera vs. otoño). Estos corderos se compararon con otros tipos comerciales amparados bajo marcas de calidad reconocidas en el mercado con denominación de Indicación Geográfica Protegida (IGP): Lechazo de Castilla-León (n= 13) y Ternasco de Aragón (n= 13). Todos los corderos fueron criados, seleccionados y sacrificados en condiciones comerciales. Tras el sacrificio, se valoró la calidad de la canal y de la carne en el músculo Longissimus thoracis y lumborum (LTL). Los lechales de Churra Tensina presentaron diferencias según la época de producción, fundamentalmente en las variables relacionadas con la composición tisular de la canal, presentando, los lechales de primavera, un mayor porcentaje de músculo y hueso, y menor de grasa que los de otoño (p≤0,001), así como una mayor proporción de los ácidos grasos C 12:0, CLA, C 20:2 n-3 o C 22:0 (p≤0,001) en la grasa intramuscular. Estas diferencias de composición no se reflejaron en el análisis sensorial, ya sea mediante panel entrenado o consumidores. La carne de los lechales de la raza Churra Tensina presentó una terneza superior (p≤0,001) a la de los productos IGP con los que se comparó, tanto instrumentalmente como sensorialmente (panel entrenado) y una mayor aceptabilidad tanto general, como del sabor y de la terneza (consumidores) (p≤0,001). Los resultados obtenidos reflejarían el potencial de dicha raza para la producción de lechales de calidad, en ambas estaciones del año.

Abstract
BACKGROUND & AIMS Health-related quality of life (HRQoL) is impaired in patients with Inflammatory Bowel Disease (IBD). The aim was prospectively to assess and validate the pattern of HRQoL in an unselected, population-based inception cohort of IBD patients from Eastern and Western Europe. METHODS The EpiCom inception cohort consists of 1560 IBD patients from 31 European centres covering a background population of approximately 10.1 million. Patients answered the disease specific Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and generic Short Form 12 (SF-12) questionnaire at diagnosis and after one year of follow-up. RESULTS In total, 1079 patients were included in this study. Crohn's disease (CD) patients mean SIBDQ scores improved from 45.3 to 55.3 in Eastern Europe and from 44.9 to 53.6 in Western Europe. SIBDQ scores for ulcerative colitis (UC) patients improved from 44.9 to 57.4 and from 48.8 to 55.7, respectively. UC patients needing surgery or biologicals had lower SIBDQ scores before and after compared to the rest, while biological therapy improved SIBDQ scores in CD. CD and UC patients in both regions improved all SF-12 scores. Only Eastern European UC patients achieved SF-12 summary scores equal to or above the normal population. CONCLUSION Medical and surgical treatment improved HRQoL during the first year of disease. The majority of IBD patients in both Eastern and Western Europe reported a positive perception of disease-specific but not generic HRQoL. Biological therapy improved HRQoL in CD patients, while UC patients in need of surgery or biological therapy experienced lower perceptions of HRQoL than the rest.

Abstract
BACKGROUND AND AIMS The EpiCom study and inception cohort was initiated in 2010 in 31 centers from 14 Western and 8 Eastern European countries, covering a 10.1million person background population. Our aim was to investigate whether there is a difference between Eastern and Western Europe in health care and education of patients with inflammatory bowel disease (IBD). METHODS A quality of care (QoC) questionnaire was developed in the EpiCom group consisting of 16 questions covering 5 items: time interval between the onset of symptoms and diagnosis, information, education, empathy and access to health care providers. RESULTS Of 1,515 patients, 947 (217 east/730 west) answered the QoC questionnaire. Only 23% of all patients had knowledge about IBD before diagnosis. In Eastern Europe, significantly more patients searched out information about IBD themselves (77% vs. 68%, p<0.05), the main source was the Internet (92% vs. 88% p=0.23). In Western Europe, significantly more patients were educated by nurses (19% vs. 1%, p<0.05), while in Eastern Europe, gastroenterologists were easier to contact (80% vs. 68%, p<0.05). CONCLUSION Health care differed significantly between Eastern and Western Europe in all items, but satisfaction rates were high in both geographic regions. Because of the low awareness and the rising incidence of IBD, general information should be the focus of patient organizations and medical societies. In Western Europe IBD nurses play a very important role in reducing the burden of patient management.

Abstract
BACKGROUND AND AIMS The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe possibly due to changes in environmental factors towards a more "westernised" standard of living. The aim of this study was to investigate differences in exposure to environmental factors prior to diagnosis in Eastern and Western European IBD patients. METHODS The EpiCom cohort is a population-based, prospective inception cohort of 1560 unselected IBD patients from 31 European countries covering a background population of 10.1 million. At the time of diagnosis patients were asked to complete an 87-item questionnaire concerning environmental factors. RESULTS A total of 1182 patients (76%) answered the questionnaire, 444 (38%) had Crohn's disease (CD), 627 (53%) ulcerative colitis (UC), and 111 (9%) IBD unclassified. No geographic differences regarding smoking status, caffeine intake, use of oral contraceptives, or number of first-degree relatives with IBD were found. Sugar intake was higher in CD and UC patients from Eastern Europe than in Western Europe while fibre intake was lower (p<0.01). Daily consumption of fast food as well as appendectomy before the age of 20 was more frequent in Eastern European than in Western European UC patients (p<0.01). Eastern European CD and UC patients had received more vaccinations and experienced fewer childhood infections than Western European patients (p<0.01). CONCLUSIONS In this European population-based inception cohort of unselected IBD patients, Eastern and Western European patients differed in environmental factors prior to diagnosis. Eastern European patients exhibited higher occurrences of suspected risk factors for IBD included in the Western lifestyle.

Abstract
AIM The aim of this paper was to compare the predictive value of glycated hemoglobin (A1c) and glucose variability (GV) in the risk of hypoglycemia in patients with type 1 diabetes (T1D). METHODS Analysis of continuous glucose monitoring performed in 130 T1D patients with a diabetes background of 17.1±8.6 years, in intensive insulin therapy (49.8±17.9 UI per day). Mean interstitial glucose (in mg/dL), GV (standard deviation of mean glucose, in mg/dL), time per day spent in hypoglycemia (interstitial glucose ≤70 mg/dL, in %), and episodes of asymptomatic or nocturnal hypoglycemia, (hypoglycemia between midnight and 8 a.m., in %), were assessed. Patients were divided into two groups: group I (N.=84) with A1C≤7.5% and group II (N.=46) with A1C>7.5%. A statistical analysis was performed using SPSS, version 21.0®. RESULTS Group I presented a significantly lower mean glucose (139.2±25.9 vs. 173.1±33.2 mg/dL, P<0.05) and GV (58.4±18.8 vs. 70.3±18.6 mg/dL, P<0.05) and more hypoglycemia time (7.65±7.04 vs. 5.35±5.64%, P<0.05). The number of patients with nocturnal hypoglycemia was not significantly different in both groups (8.7 vs. 5.8%, P>0.05). Hypoglycemia time was positively correlated with GV (r=0.23, P=0.01) and negatively with A1C and mean glucose (r=-0.23 and r=-0.36; P=0.01). In multivariate analysis, GV and mean glucose were associated with hypoglycemia time (β=0.22 and β=-0.15, P<0.01, respectively), independent of A1c, diabetes duration and insulin dose; nocturnal hypoglycemia was only associated with mean glucose (OR=0.9, P<0.05) and was associated with a 16-fold increased risk of asymptomatic hypoglycemia (OR: 16.9, P<0.01). CONCLUSION Patients with high HbA1c still remain at risk of hypoglycemia. Glucose variability independently predicts daily time spent in hypoglycemia. At night, hypoglycemia only correlates with mean glucose, suggesting that daily fluctuations are probably due to inadequate meals insulin coverage. The potential of GV for predicting hypoglycemia time supports the inclusion of measures of GV into a global diabetes strategy.

Abstract
OBJECTIVES To identify occupational stressors and coping resources in a group of physiotherapists, and to analyse interactions between subjective levels of stress, efficacy in stress resolution and coping resources used by these professionals. DESIGN A sample of 55 physiotherapists working in three general hospitals in Portugal completed the Coping Resources Inventory for Stress, the Occupational Stressors Inventory and two subjective scales for stress and stress resolution. MAIN RESULTS Most physiotherapists perceived that they were moderately stressed (19/55, 35%) or stressed (20/55, 36%) due to work, and reported that their efficacy in stress resolution was moderate (25/54, 46%) or efficient (23/54, 42%). Issues related to lack of professional autonomy, lack of organisation in the hierarchical command chain, lack of professional and social recognition, disorganisation in task distribution and interpersonal conflicts with superiors were identified as the main sources of stress. The most frequently used coping resources were social support, stress monitoring, physical health and structuring. Perceived efficacy in stress resolution was inversely related to perceived level of occupational stress (r=-0.61, P<0.01). Significant correlations were found between several coping resources and the perceived level of stress and efficacy in stress resolution. Associations between problem solving, cognitive restructuring and stress monitoring and both low levels of perceived stress and high levels of perceived efficacy were particularly strong. IMPLICATIONS FOR PRACTICE The importance of identifying stressors and coping resources related to physiotherapists' occupational stress, and the need for the development of specific training programmes to cope with stress are supported.

Abstract
This work investigated the cytotoxic and genotoxic potential of water from the River Paraíba do Sul (Brazil) using Allium cepa roots. An anatomo-morphological parameter (root length), mitotic indices, and frequency of micronuclei were analysed. Eight bulbs were chosen at random for treatment for 24 to 120 hours with the River water collected in the years of 2005 and 2006 from sites in the cities of Tremembé and Aparecida (São Paulo state, Brazil). Daily measurements of the length of the roots grown from each bulb were carried out throughout the experiment. Mitotic index (MI) and frequency of micronuclei (MN) were determined for 2000 cells per root, using 3-5 root tips from other bulbs (7-10). Only in the roots treated with samples of the River water collected in 2005 in Tremembé city was there a decrease in the root length growth compared to the respective control. However, a reduction in MI values was verified for both sites analysed for that year. Considering the data involving root length growth and especially MI values, a cytotoxic potential is suggested for the water of the River Paraíba do Sul at Tremembé and Aparecida, in the year of 2005. On the other hand, since in this year the MN frequency was not affected with the river water treatments, genotoxicity is not assumed for the river water sampled at the aforementioned places.

Abstract
The purpose of this study was to conduct a survey examining the impact of inflammatory bowel disease (IBD) on patients' and their caregivers' daily activities. Questionnaires were distributed to patients registered in the APDI (Portuguese Association for IBD) database and their respective caregivers in 2007. Of 422 patient respondents, 251 had Crohn's disease (CD) and 171 had ulcerative colitis (UC), with the majority of patients being women (58.1%) and aged over 40 years (37.4%). The number of disease flares experienced by IBD patients was slightly higher for patients with CD than for patients with UC (2.64 vs. 2.34), and surgery was more often required in CD patients as compared to UC patients (42.4 vs. 7%). Sixty percent (60%) of patients reported having no problems with mobility, daily activities, or personal hygiene; however, over half of all patients experienced some pain and anxiety. Adult patients and children and adolescents respectively experienced time off work or school due to their disease but caregivers were not affected in this regard. The caregivers life (N=324) was affected by anxiety, with the major concern reported as the risk of the patient developing cancer. Both IBD patients and caregivers thought that the provision of information on new drugs and contact time with a doctor would have the biggest impact on improving care. The symptoms and complications of IBD have a considerable impact on the lives of patients and their caregivers, and several actions could be taken to improve their care.

Abstract
This article reports the first approach to the antioxidant potential evaluation of the edible mushroom Leucopaxillus giganteus mycelium obtained in the presence of four different carbon sources: glucose, sucrose, fructose and mannitol. Despite the use of Leucopaxillus mushroom species in chemical industry for extraction of clitocybin antibiotic, the production of its mycelium for pharmacological applications has not been explored. The concentration of antioxidant compounds increased along the growth time as a response to the oxidative stress and therefore free radicals production. The aldohexose glucose proved to be the most appropriate carbon source to increase antioxidant activity, leading to the highest phenols content and lowest EC50 values. Significant negative linear regressions were established between phenols and flavonoids contents, and antioxidant activity, which support that the extracts mechanism of action for the different antioxidant activity assays may be identical, being related with the content in those compounds and their free radical scavenging activity.

Abstract
OBJECTIVE To determine the spectrum of MEN1 mutations in Portuguese kindreds, and identify mutation-carriers. PATIENTS, DESIGN AND RESULTS Six unrelated MEN1 families were studied for MEN1 gene mutations by single-strand conformational polymorphism (SSCP) and DNA sequence analysis of the coding region and exon-intron boundaries of the MEN1 gene. These methods identified 4 different heterozygous mutations in four families: two mutations are novel (mt 1539 delG and mt 655 ims 11 bp) and two have been previously observed (mt 735 del 46p and mt 1656 del C) all resulting in a premature stop codon. In the remaining two families, in whom no mutations or abnormal MEN1 transcripts were detected, segregation studies of the 5' intragenic marker D11S4946 and codon 418 polymorphism in exon 9 revealed two large germline deletions of the MEN1 gene. Southern blot and tumour loss of heterozygosity analysis confirmed and refined the limits of these deletions, which spanned the MEN1 gene at least from: exon 7 to the 3' untranslated region, in one family, and the 5' polymorphic site D11S4946 to exon 9 (obliterating the initiation codon), in the other family. Twenty-six mutant-gene carriers were identified, 6 of which were asymptomatic. CONCLUSIONS These results emphasize the importance of the detection of MEN1 germline deletions in patients who do not have mutations of the coding region. Important clues indicating the presence of such deletions may be obtained by segregation studies using the intragenic polymorphisms D11S4946 and at codon 418. The detection of these mutations will help in the genetic counselling of clinical management of the MEN1 families in Portugal.

Abstract
The aim of this study was to describe the clinical course of Crohn's disease (CD) in a well-defined, homogeneous groups of patients. A total of 480 patients with CD were followed up from diagnosis up to 20 years. Definitions of patient subgroups were made according to the Vienna Classification. Markov chain analysis was used to estimate the probabilities of remissions and relapses during the disease course. Both age at diagnosis and behavior were associated with different disease locations. Patients with ileal disease had a greater need for surgical and a lesser need for immunosuppressive treatment; patients with ileocolonic disease were diagnosed at an earlier age and showed a lower probability of remaining in remission during the disease course; patients with colonic disease needed less surgical or steroid treatments; patients with intestinal penetrating disease were frequently submitted to abdominal surgery, whereas those with anal-penetrating disease often needed immunosuppressive treatment. Approximately 40% of the patients were in clinical remission at any time, but only about 10% maintained a long-term remission free of steroids after their initial presentation. A more benign clinical course could be predicted in patients who stay in remission in the year after diagnosis. The grouping of patients with CD according to the Vienna Classification and/or the clinical activity in the year after diagnosis is useful in predicting the subsequent course of disease.

Abstract
The hyperparathyroidism-jaw tumour (HPT-JT) syndrome is an autosomal dominant disease characterized by the occurrence of parathyroid tumours and fibro-osseous tumours of the jaw bones. Some HPT-JT patients may also develop renal abnormalities, which include Wilms' tumours, hamartomas and polycystic disease. The HPT-JT gene has been mapped to chromosome 1q25-q31, and we report the clinical and genetic findings in a kindred from central Portugal. HPT-JT was observed in six members from three generations; all had primary hyperparathyroidism (five had parathyroid adenomas, one a parathyroid carcinoma). Ossifying jaw fibromas affecting the maxilla and/or mandible were observed in 5/6. Renal cysts (<2.5 cm) were observed in four. Genetic studies using 18 polymorphic loci from chromosome 1q25-q31, together with leukocyte DNA from 11 family members and tumour DNA from three parathyroids (two adenomas and one carcinoma), revealed loss of tumour heterozygosity in the parathyroid carcinoma only, and the retained haplotype was found to cosegregate with the disease in the six affected members. A new Portuguese kindred with the HPT-JT syndrome that maps to chromosome 1q25-q31 has been identified, and these findings will help in the further characterization of this inherited disorder.

Abstract
OBJECTIVE To assess GH secretion in young adults treated with GH replacement therapy in childhood. PATIENTS AND METHODS From the 38 patients who concluded treatment with GH, we studied 20 (52.6%), 9 girls and 11 boys. Thirteen had Growth Hormone Deficiency (GHD)-65%, while 7 had Multiple Pituitary Hormone Deficiency (MPHD)-35%. The patients were retested within 6 months to 6 years after completing GH therapy. The mean age (+/- SD) at retesting was 18.1 +/- 2.6 years for those with GHD and 20.8 +/- 2.8 for those with MPHD. At reassessment we performed two provocative tests: insulin tolerance test (ITT) and clonidine test. RESULTS Seven of the 20 patients retested, retained GH deficiency. Of the 13 patients with GHD, only one maintained the deficiency, while of the 7 patients with MPHD, 6 maintained the deficiency. CONCLUSION Young adults with GH deficiency treated with this hormone should be retested in order to identify those who are truly GH insufficient adults and may benefit from replacement therapy.

Abstract
A total of 618 patients with end-stage renal disease received kidney transplants between 1980 and September 1996. Twenty eight of them were diabetics. Better results were achieved for type 1 diabetic patients than for type 2 (mortality: 5.9% vs 27.3%; functioning graft: 88.2% vs 72.7%). The morbility was also higher in those patients (infections: 81.8% vs 29.4%; vascular complications: 45.5% vs 17.6%). Actuarial patient and graft survival were lower for type 2 than for non diabetic patients. For type 1 diabetics the results are similar to those for non diabetics. Better results can probably be achieved by restricting the selection criteria. The decision to transplant or maintain on dialysis should be made on a case by case basis.

Abstract
Pituitary apoplexy is rare and endocrine remission in patients with apopletic secreting pituitary adenomas is even rarer. This study reports on two patients with pituitary macroadenomas (one with Cushing's disease and the other with acromegaly) in whom endocrine remission occurred after apoplexy. The first patient had Cushing's disease and had an ictus of headache and vomiting after which she started a progressive remission of hypercortisolism. A post-apoplexy MRI disclosed persistence of a sellar and supra-sellar mass. She was submitted to transesphenoidal surgery. An hypertensive hemorrhagic cyst was found with no tumor. The second patient had acromegaly. While performing a LHRH-stimulation test he had an ictus of headache, vomiting, no visual loss and appearance of diabetes insipidus. A CT scan disclosed an intrasellar hematoma. Despite the size of the tumor and since there was no visual impairment, this patient was followed up without surgery. Imaging follow-up showed a progressive shrinkage and disappearance of the mass, which was corroborated by endocrine remission. A high rate of recurrence is reported in such patients in the literature. Both patients are being currently followed-up on a long-term basis.

Abstract
OBJECTIVE To determine the prevalence of hypertension (HT) in patients with Cushing's syndrome. PATIENTS AND METHODS We studied 23 patients with Cushing's syndrome, 17 women (mean +/- SD age = 42.8 +/- 15.6 years) and 6 men (mean +/- SD age = 34.8 +/- 10.2 years). The etiologies were: 16-Cushing's disease, 3-suprarenal adenoma, 2-suprarenal carcinoma and 2-iatrogenic. Blood pressure (BP) was measured at least three times and we consider hypertension when systolic BP > or = 140 mmHg and/or diastolic BP > or = 90 mmHg. RESULTS The prevalence of HT, at diagnosis, was 73.9% (64.7% in women and 100% in men) and the mean BP was 163 +/- 25/100 +/- 16 mmHg (158 +/- 26/97 +/- 15 mmHg in women and 182 +/- 5/114 +/- 10 mmHg in men). From the 16 patients with Cushing's disease, 13 (81%) had HT; all the patients (n = 3) with suprarenal adenoma had HT; none with suprarenal carcinoma (n = 2) had HT and only 1 of the 2 patients with iatrogenic Cushing's syndrome had HT. After treatment, 14 patients entered remission, 6 persisted with active disease and 1 was missed during the follow-up. In the group of patients that entered remission, the prevalence of HT at diagnosis was 78.5% (n = 11), 57.1% (n = 8) being after treatment. CONCLUSIONS In this study, we found a high prevalence of HT at diagnosis (73.9%). After treatment and in the patients that entered remission, the prevalence of HT remained high (78.5% vs 57.1%). The high prevalence of HT in Cushing's syndrome, suggests its importance as a morbidity factor and also as an important diagnostic indicator, when present.

Abstract
The expression of Brazil nut storage albumin genes is highly regulated during seed development. Several sequences in the promoter of one of these genes show homologies with the target sites of the maize O2 bZIP regulatory protein. We therefore asked whether the O2 protein would recognize these promoter sequences. We show that the O2 protein binds to three different sequences (F1, F2 and F3). F1 and F3 are hybrid C/G and A/G boxes, respectively, that are homologous to the O2-binding site of a maize alpha-zein gene. F2 is a new O2-binding sequence related to the O2 target sites of the Coix alpha-coxin, the maize b-32 genes and the AP-1 pseudopalindrome. Molecular modelling showed that an Asn and a Ser in the 02 DNA binding domain make different base-specific contacts with each operator. 5' Promoter deletions of the be2S1 gene showed that the domain containing the O2 target sites F1 and F2 is required for detectable reporter gene expression in transgenic tobacco seeds. Moreover, the homologous coix O2 protein was shown to in situ transactivate the promoter region encompassing the three O2-binding sites F1, F2 and F3. Thus, these sites may be in vivo regulatory sequences mediating activation by bZIP regulatory proteins.

Abstract
OBJECTIVE To analyse the type and frequency of cranial CT and NMR imaging anomalies in children of short stature. PATIENTS AND INTERVENTIONS We studied 57 children of short stature with a mean age (+/-SD) of 10.1 +/- 3.8 years, 34 boys and 23 girls, all of them with auxometric criteria of GH deficiency. After studying the pituitary function and determination of karyotype in the girls, the children were classified in to five groups:-Isolated GHD (IGHD) (n = 32), multiple pituitary hormone deficiency (MPHD) (n = 6), neurosecretory dysfunction (NSD) (n = 8), Turner syndrome (n = 7) and idiopathic short stature (ISS) (n = 4). The imaging methods used were cranial CT or NMR. RESULTS Of the 57 children studied the CT/NMR was abnormal in 37(64.9%) children. We found anomalies in 65.6% of IGHD patients, 62.5% of NSD patients, 100% of MPHD patients and 57.1% and 25% in the Turner s. patients and ISS patients respectively. The most frequent anomaly was hypoplastic pituitary found in 50% of IGHD patients, 37.5% of NSD patients and 33.3% of MPHD patients. None of the cases of Turner s. or ISS had hypoplastic pituitary. An empty sella was the second most frequent anomaly found in 7 patients (IGHD-3, MPHD-3, DNS-1). Of the 25 children in which NMR was performed, 8 had hypoplastic pituitary and stalk and 2 had interruption of the pituitary stalk and ectopic neurohypophysis. CONCLUSION These results strengthen the necessity for CT/NMR imaging in children of short stature which, besides allowing identification of tumors, also permits the diagnosis of idiopathic GHD because of its frequent association with cranial imaging anomalies, mainly hypoplastic pituitary.

Abstract
AIM To estimate the prevalence of hypertension (HT) in a group of patients with acromegaly at the moment of diagnosis and after treatment. PATIENTS AND METHODS Fifty-seven patients, 43 females and 14 males with a mean age of 45.19 +/- 11.9 years were studied retrospectively. In the last visit 9 patients (15.7%) were in remission and 47 (84.2%) had active acromegaly. We considered hypertensive the patients with systolic BP > or = 140 and/or diastolic BP > or = 90 mmHg. Hypertension was classified in four stages:- mild, moderate, severe and very severe. RESULTS The prevalence of hypertension at the moment of diagnosis was 35%. The hypertensive patients had a mean age of 51.75 +/- 9.3 years and normotensive patients 41.65 +/- 11.6 years (p < 0.001). In females the prevalence of HT was 27.9% and in males it was 57% (p = NS). In hypertensive patients (n = 20), the mean BP was 159 +/- 15 (syst.)/97.2 +/- 9.8 (diast.), 16 patients (80%) had mild to moderate HT and the remainder had severe (n = 2) and very severe (n=1) HT. In the last visit, 22.2% of patients were cured and 46.8% of those with active acromegaly were hypertensive. None of the patients cured and initially normotensive developed HT; among those that were hypertensive (n = 3), 2 remained hypertensive and 1 became normotensive. Among patients with active acromegaly and initially normotensive, 7 developed HT 4.85 +/- 2.03 years later; of those hypertensive at diagnosis (n = 16), only one became normotensive. The last case was 27 years old. The patients that remained hypertensive had a mean age of 53.8 +/- 6.85 years (41-62 years). CONCLUSIONS The prevalence of hypertension at the moment of diagnosis was 35%, similar to the majority of studies published and higher than the general population. The hypertensive patients were significantly older the normotensive patients and most of them had mild to moderate HT. We observed an increase in the prevalence of HT over the years in the cases that maintained active acromegaly. In our series only one of the three patients cured became normotensive, therefore, we concluded that HT in acromegaly is frequently irreversible. The chances of normalization seems higher in younger patients and probably with a shorter duration of acromegaly.

Abstract
AIMS To study the circadian variation of BP in diabetics with chronic late complications (autonomic neuropathy, peripheral neuropathy and macroangiopathy of the lower limbs). PATIENTS AND METHODS We studied 35 NIDDM patients, 22 male and 13 female, with a mean age of 62.17 +/- 8.66 years, all with hypertension (HBP) or with BP levels close to normal, many of them under anti-hypertensive therapy (mean BP in clinical measurements: 164 +/- 23.16 mmHg systolic and 92.14 +/- 11.06 mmHg diastolic). Twenty-four suffer from autonomic neuropathy, 23 from peripheral neuropathy and 11 from macroangiopathy of the lower limbs. The control group is composed of 10 patients with essential HBP without other observable pathology, with a mean age of 68.5 +/- 3.63 years and BP in clinical measurements: systolic 192 +/- 15.49 mmHg and diastolic 88 +/- 4.21 mmHg (without any previous therapy). The record of the BP circadian profile was made, with the use of a Spacelab monitor, model 90207, 5 days after anti-hypertensive therapy was suspended. RESULTS The mean BPs in 24 hours were: control group-systolic BP 152.6 +/- 13 mmHg and diastolic 79.8 +/- 13 mmHg; diabetics-systolic BP 136.82 +/- 15 mmHg and diastolic 77.4 +/- 8 mmHg. The daily and nocturnal mean BPs were 158.5 +/- 8.5 and 146 +/- 8.4 mmHg (systolic) and 82.8 +/- 5.7 and 70.9 +/- 5.1 mmHg (diastolic) in the control group, while they were, in diabetics, 141.3 +/- 15.7 and 135.6 +/- 16.6 mmHg (systolic) and 79.6 +/- 7.1 and 72 +/- 8.2 mmHg (diastolic). In diabetic patients, considering the groups with and without autonomic neuropathy, the difference between daily and nocturnal mean BP was 1.6 vs 9.4 mmHg systolic and 4.9 vs 9.4 mmHg, diastolic. CONCLUSIONS In both groups, the mean BP levels in 24 hours were notoriously lower than those obtained from the clinical measurements: the differences were 40 mmHg (control group) and 27.2 mmHg (diabetics) for systolic BP and 8.2 mmHg (control group) and 14.7 mmHg (diabetics) for diastolic. The BP circadian profiles show a lower variability, with absence of the nocturnal reduction, specially evident in diabetic patients with autonomic neuropathy versus other groups.

Abstract
UNLABELLED Posttransplant Diabetes Mellitus (PTDM) has traditionally been attributed to therapy with steroids, however with the introduction of Cyclosporine (cya) into clinical practice, an increase in the incidence of PTDM was noted. We studied the prevalence of PTDM in Renal transplant recipients and its clinical characteristics. MATERIALS AND METHODS 355 patients were submitted to a renal transplant between 30/06/80 and 31/12/92. After stabilization of the doses of the immunosuppressive therapy we considered diabetic patients those with fasting glycemic values > or = 140 mg/dl and those with glycemic values between 100-140 mg/dl were given to an oral glucose tolerance test (WHO criteria 1985). RESULTS Posttransplant diabetes mellitus occurred in 28 patients (7.9%), 11 females with a mean age of 53.36 +/- 12.75 years and 17 males with a mean age of 51.05 +/- 10.60 years. DISCUSSION Due to the great prevalence of alterations in glucose tolerance and their adverse effects on the cardio-vascular system, we think that all renal transplant recipients should be screened.

Abstract
1. Zinc is a metal important for several biological functions including neuromodulation and neurotransmission in the central nervous system. 2. In the present paper we studied the acute effects of third ventricle injections (2 microliters) of minute amounts of zinc acetate on the water intake of male, adult, Wistar rats (N = 7-14) under three conditions: water deprivation (14 h, overnight) and after third ventricle injections of carbachol (11 nmoles/rat in 2 microliters) or angiotensin II (AII, 9.6 pmoles/rat in 2 microliters). 3. Central injections of zinc acetate in different doses (0.3 and 3.0 nmoles/rat) induced a partial blockade of water intake of rats under all three conditions studied. Water intake after 120 min in control dehydrated rats (those receiving NaAc instead of Zn(Ac)2) was 7.89 +/- 0.47 ml while dehydrated animals receiving Zn(Ac)2 in the highest dose employed (3.0 nmoles/rat) was 2.90 +/- 0.75 ml. Carbachol-induced water intake after 45 min was 5.49 +/- 0.83 ml. This value was significantly reduced in zinc-treated (3.0 nmoles/rat) animals receiving carbachol (2.41 +/- 0.84 ml). Angiotensin-treated animals exhibit a water intake of 3.85 +/- 0.48 ml after 45 min, a value reduced to 1.13 +/- 0.6 ml in those animals receiving angiotensin II plus zinc (3.0 nmoles/rat). 4. It is suggested that zinc alters the functional integrity of cholinergic and angiotensinergic systems in the central nervous system mediating water-intake behavior in rats.
