Abstract
We present the case of a 41-year-old man with Rapp-Hodgkin syndrome who underwent nasal septum deviation surgery under general anaesthesia. This syndrome is rare, with approximately 70 cases reported worldwide. It is one of a group of ectodermal dysplasia syndromes and results from the aberrant development of ectoderm during fetal development. Some of the clinical features may affect anaesthetic management. The most important considerations are potentially difficult airway management, the need for meticulous temperature control, and the importance of skin protection. This case was uneventful, but as there are few case reports on the management of patients with ectodermal dysplasia syndromes undergoing anaesthesia this report contributes useful knowledge. The pathogenesis and clinical features of Rapp-Hodgkin syndrome and the anaesthetic management for this patient are described.

Abstract
We report a case of a previously healthy patient who developed a vertebral canal haematoma in the subarachnoid and subdural spaces after a spinal puncture for elective caesarean section. Vertebral canal haematomas are rare. There are different mechanisms for haematoma formation, but coagulation disturbances and trauma, most often due to needle punctures, are the most important. Vertebral canal haematoma may warrant emergent surgical decompression. In this case report we discuss vertebral canal haematomas, including possible mechanisms, clinical diagnosis, imaging modalities, methods for management and advice for patients. We consider the possible association between a vertebral canal haematoma and non-steroidal anti-inflammatory drugs, and draw attention to an existing black box warning for ketorolac. In this case, we explain why a conservative approach was chosen with a good outcome. We also report the effect of this complication on the patient experience.

Abstract
BACKGROUND Colon capsule endoscopy (CCE) is a minimally invasive alternative for patients unwilling to undergo conventional colonoscopy, or for whom the latter exam is contraindicated. This is particularly important in the setting of colorectal cancer screening. Nevertheless, these exams produce large numbers of images, and reading them is a monotonous and time-consuming task, with the risk of overlooking important lesions. The development of automated tools based on artificial intelligence (AI) technology may improve some of the drawbacks of this diagnostic instrument. METHODS A database of CCE images was used for development of a Convolutional Neural Network (CNN) model. This database included anonymized images of patients with protruding lesions in the colon or patients with normal colonic mucosa or with other pathologic findings. A total of 3,387,259 frames from 24 CCE exams were retrospectively reviewed. For CNN development, 3640 images (860 protruding lesions and 2780 with normal mucosa or other findings) were ultimately extracted. Training and validation datasets were constructed for the development and testing of the CNN. RESULTS The CNN detected protruding lesions with a sensitivity, specificity, positive and negative predictive values of 90.7, 92.6, 79.2 and 96.9%, respectively. The area under the receiver operating characteristic curve for detection of protruding lesions was 0.97. CONCLUSIONS The deep learning algorithm we developed is capable of accurately detecting protruding lesions. The application of AI technology to CCE may increase its diagnostic accuracy and acceptance for screening of colorectal neoplasia.

Abstract
Background: Anal squamous intraepithelial lesions (ASIL) are precancerous lesions of anal squamous cell carcinoma, with a higher prevalence in immunosuppressed patients. There are some studies in kidney transplant recipients, but there is no information regarding prevalence in liver transplantation. Our aim was to evaluate the prevalence of ASIL in this setting. Methods: Prospective case–control study involving liver transplant recipients without any other known risk factor for ASIL (n=59), which were compared with a healthy control group (n=57). All were submitted to anal cytology and high-resolution anoscopy was performed in those with abnormal results. Results: Ten (17%) of liver transplant recipients had abnormal cytological results, seven patients had atypical squamous cells of undetermined significance (ASC-US), one patient had atypical squamous cells that cannot exclude high-grade (ASC-H) and two patients had high-grade squamous intraepithelial lesions (HSIL). In the control group, one patient (2%) had an ASC-US result (P=0.005). Anal squamous intraepithelial lesions were confirmed in 7 out of 10 of liver transplant patients and 0 out of 1 in the controls (P=0.013) by high-resolution anoscopy with biopsies. Current smoking was the only risk factor for abnormal cytology (odds ratio=5.87, 95% confidence intervals=1.22–28.12, P=0.027). Conclusions: Liver transplant patients have a higher risk of ASIL. Screening should be considered, especially in smokers.

Abstract
Congenital generalised lipodystrophy is a rare autosomal recessive disorder characterised by a marked deficiency of adipose tissue and usually recognised at birth. This disorder is associated with early development of metabolic complications such as hypertriglyceridemia, hepatic steatosis, and insulin resistance. These complications ultimately lead to fatal events as a consequence of early atherosclerosis, lipoatrophic diabetes and hepatic cirrhosis. The authors report the case of a patient diagnosed, based on clinical and laboratory findings, in the first year of life. The established diagnosis was then confirmed by identifying a mutation in the BSCL2 gene. Because the hypertriglyceridemia and diabetes were refractory to treatment, the authors present this case in order to reflect on the best therapeutic management of this pathology.

Abstract
Vitamin D has important immuno-modulatory properties and it influences insulin secretion. It acts through a vitamin D receptor (VDR), for which several gene polymorphisms have been described. The Uruguayan population presents several epidemiological characteristics that make it different from that of other counties, including other Latin-American countries. It went through miscegenation processes, with a tri-hybrid European, Amerindian and African origin, with no contribution from isolated Amerindian communities. Such differences have important consequences for the relationship between frequencies of several genes in the general population and their association with the diabetes mellitus. We examined the prevalence of VDR gene polymorphisms in the general population and their relation to type 1 diabetes in a parent-case design. One hundred unrelated individuals from the general population and 45 parent-patient triads with a child affected with type 1 diabetes were genotyped for FokI, BsmI and TaqI VDR gene polymorphisms by RFLP-PCR. We used a transmission disequilibrium test to assess preferential transmission of parents to affected offspring. The prevalence of the three VDR polymorphisms was: allele F = 48%, B = 35%, T = 64%. The f, b, T alleles and heterozygous genotypes were found at a high frequency in this population. Among 36 informative heterozygous parental genotypes, 30 transmitted the F allele (probability of transmission = 83%). The other two polymorphisms did not show significant transmission. We suggest that FokI polymorphism indicates susceptibility to type 1 diabetes mellitus in the Uruguayan population.

Abstract
20030 Background: The relation between apoptosis-related molecules and chemosensitivity has been extensively studied. In recent years, attention has shifted to a new family of inhibitor of apoptosis proteins (IAPs). XIAP (X- linked inhibitor of apoptosis) is the most versatile and potent member of the IAP family. To date, the overexpression of XIAP has been detected in various cancers. XAF1 (X-linked inhibitor of apoptosis associated factor 1) is a new protein identified for its ability to interact with XIAP. Neither XIAP nor XAF1 or XIAP/XAF1 mRNA expression have been studied in bladder cancer patients. Methods: The expression of XIAP and XAF1 mRNA was analyzed by a real time quantitative fluorogenic PCR method in a group of 17 patients with locally advanced bladder cancer treated with a combination of neoadjuvant Gemcitabine and Cisplatin. The prognostic significance of XIAP and XAF1 mRNA expression and the correlation with several clinicopathological variables was evaluated. Results: XIAP and XAF1 mRNA expression was detected in all 17 (100%) case samples. The levels of XIAP mRNA expression showed a moderate variation among samples. In contrast, XAF1 and XIAP/XAF1 mRNA levels showed significant variation among samples. Bivariate correlation analyses revealed a significant positive Spearman direct correlation coefficient between the XIAP expression and the pathological response. No significant correlation was found for XAF1 expression as well as for the XIAP/XAF1 ratio and clinical and pathological response. Conclusions: This is first study to address the role of XIAP, its negative regulator XAF1, and the XIAP/XAF1 ratio in bladder cancer patients. The positive correlation between the XIAP mRNA expression and the pathological response is in line with a previous study from our group in which a correlation was found between XIAP expression and survival. All these observations point to a complex role of XIAP in tumor biology. XAF1 mRNA expression in bladder carcinomas did not achieve significance as an independent predictive and prognostic factor in a bivariate analysis. Further studies are necessary in order to better assess a possible clinical value for XIAP and XAF1 as predictive and prognostic markers in cancer patients. No significant financial relationships to disclose.

Abstract
14590 Background: Gemcitabine and cisplatin (GC) is an active and well tolerated combination in the treatment of metastatic bladder cancer (BC). Studies of neoadjuvant chemotherapy in BC suggest improved survival, especially for patients with complete pathologic response. We have prospectively analyzed the tolerability and efficacy of GC as neoadjuvant treatment of invasive BC. Methods: in this single-institution, one-stage phase II trial, patients (pts) with histologically verified muscle-invasive transitional cell carcinoma received 3 cycles of gemcitabine 1200 mg/m2 on days 1 and 8 with cisplatin 75 mg/m2 on day 1 prior to surgery. Radiologic response was evaluated with computed tomography and magnetic resonance imaging. Planned accrual was 35 pts. Primary endpoint was clinical and pathological response rate. Results: between Jun 2002 and Mar 2005, 22 pts (19 males) were enrolled. Accrual was poor due to a higher percentage of superficial tumors than expected. Median age was 61 years. All pts had Performance Status 0 or 1. Initial stage was II (T2) in 11 and III (T3–4) in 11 pts. Chemotherapy was well tolerated with infrequent grade III/ IV toxicity (nausea/ vomiting in 27%, neutropenia in 23% and neutropenic fever in 1 patient). Median follow-up is 26 months (6–40). Partial radiologic response rate was documented in 15 out of 19 assessable pts (79%). One patient was excluded due to renal toxicity in the first chemotherapy cycle and other had sarcomatoid carcinoma at definitive pathologic examination. By Dec 2005, 14 pts underwent radical cystectomy, 4 pts pelvic radiotherapy, 1 is waiting surgery and 1 had systemic progression before surgery. Nine out of 20 pts (45%) relapsed (8 systemic and 1 local) and 4 (20%) are dead (3 with confirmed disease progression). Complete pathologic response was observed in 3 pts (21.5% of 14) and local progression during chemotherapy in another 3 pts. Median estimated progression-free survival by Kaplan-Meier is 27 months (CI 95% 20.5–33.5) with median overall survival not reached. Conclusions: the combination of gemcitabine and cisplatin is effective and tolerable when used as neoadjuvant therapy in muscle-invasive bladder cancer. Longer follow-up is necessary to evaluate its impact in the overall survival of these pts. [Table: see text]

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
In the present work the sensitivity of yeast strains of Kluyveromyces marxianus, Pichia anomala, Candida utilis, Schizosaccharomyces pombe and Saccharomyces cerevisiae, to the fungicides cymoxanil, penconazol, and dichlofluanid, was evaluated. Dichlofluanid induced the most negative effects, whereas penconazol in general was not very toxic. Overall, our results show that the parameters IC50 for specific respiration rates of C. utilis and S. cerevisiae and C(D) for cell viability of S. cerevisiae can be applied to quantify the toxicity level of the above compounds in yeast. Hence, could be explored as an alternative or at least as a complementary test in toxicity studies and, therefore, its potential for inclusion in a tier testing toxicity test battery merits further research.

Abstract
BACKGROUND The goal of surgery for morbid obesity is to achieve a good and durable loss of weight and improve health. Previous studies have demonstrated a significant weight loss for the Swedish adjustable gastric band (SAGB). PATIENTS AND METHODS Between November 1996 and April 1998, 18 morbidly obese patients underwent SAGB laparoscopically. Their mean age at surgery was 35 years. The mean preoperative weight was 128 kg (range 89-163), and the mean body mass index was 50.4+/-9. Comorbidity was present in 13 patients. RESULTS One gastric perforation occurred, and in one patient it was not possible to create the pneumoperitoneum. Regarding late morbidity, one intragastric migration and one slippage of the band occurred. There was no mortality. CONCLUSION The low morbidity, the good results with weight loss, and the improvement in comorbidity lead the authors to believe that Swedish adjustable gastric banding for the treatment of morbidly obese patients is a successful means of losing weight and improving general health.

Abstract
In glucose-grown cells of Saccharomyces cerevisiae IGC 4072, acetic acid enters only by simple diffusion of the undissociated acid. In these cells, ethanol and other alkanols enhanced the passive influx of labelled acetic acid. The influx of the acid followed first-order kinetics with a rate constant that increased exponentially with the alcohol concentration, and an exponential enhancement constant for each alkanol was estimated. The intracellular concentration of labelled acetic acid was also enhanced by alkanols, and the effect increased exponentially with alcohol concentration. Acetic acid is transported across the plasma membrane of acetic acid-, lactic acid-, and ethanol-grown cells by acetate-proton symports. We found that in these cells ethanol and butanol inhibited the transport of labelled acetic acid in a noncompetitive way; the maximum transport velocity decreased with alcohol concentration, while the affinity of the system for acetate was not significantly affected by the alcohol. Semilog plots of Vmax versus alcohol concentration yielded straight lines with negative slopes from which estimates of the inhibition constant for each alkanol could be obtained. The intracellular concentration of labelled acid was significantly reduced in the presence of ethanol or butanol, and the effect increased with the alcohol concentration. We postulate that the absence of an operational carrier for acetate in glucose-grown cells of S. cerevisiae, combined with the relatively high permeability of the plasma membrane for the undissociated acid and the inability of the organism to metabolize acetic acid, could be one of the reasons why this species exhibits low tolerance to acidic environments containing ethanol.

Abstract
We here report a male patient with an additional t(3;21)(q26;q22) in Philadelphia positive chronic myelogenous leukemia (Ph + CML). In spite of the presence of this progression of disease marker and probably related to alpha-interferon therapy, this case entered into remission as a second chronic phase. At that time, he underwent allogeneic bone marrow transplantation. One year after BMT he showed a disappearance of leukemic clones at the cytogenetic and molecular levels. At present the patient has 21 months of clinical and hematologic remission. It is of interest to note that the association of alpha-interferon-hydroxyurea and bone marrow transplantation might produce a negative selection pressure against the leukemic clone in this patient.

Abstract
Ethanol at concentrations above 12% (v/v) in mineral medium with glucose and with ammonium as the only nitrogen source induced rapid inactivation of the ammonium transport system in the strain IGC 3507 of Saccharomyces cerevisiae terminating protein synthesis. Subsequently, when glucose was present, the glucose transport system was irreversibly inactivated. This two-step mechanism may play a decisive role when ethanol stops fermentation by S. cerevisiae, before all the fermentable sugar has been consumed.

Abstract
Hypothalamic tissue levels of nine regulatory peptides (bombesin, calcitonin gene-related peptide [CGRP], galanin, neuromedin B, neuropeptide Y [NPY], neurotensin, somatostatin, substance P, and vasoactive intestinal peptide [VIP]) were compared in Aston obese diabetic (ob/ob) and lean (+/?) mice aged 4, 16, and 28 weeks. Neurotensin concentrations were significantly lower in ob/ob mice than in lean mice, with a 20% reduction (P = .03) in the whole hypothalamus at 4 weeks of age, a 24% reduction (P = .009) in the lateral hypothalamus at 16 weeks, and a 50% reduction (P = .0007) in the central hypothalamus at 28 weeks of age. Apart from a 42% increase in vasoactive intestinal peptide concentrations in the central hypothalamus of ob/ob mice at 28 weeks (P = .02), levels of the other eight peptides examined did not differ significantly between obese and lean groups. Neurotensin is known to cause anorexia and increased energy expenditure when injected into the central hypothalamus. Reduced hypothalamic neurotensin concentrations may reflect reduced neurotensinergic activity, which might contribute to hyperphagia and decreased energy expenditure, two major defects that contribute to obesity and diabetes in the ob/ob syndrome.

Abstract
1. Vasoactivity of human A- and B-calcitonin-gene-related peptides was studied in normal subjects, using reflectance plethysmography to measure relative changes in blood flow produced by superficial subcutaneous injections of the peptides. 2. Injection of 10(-11) mol of either peptide caused an immediate 200% increase in local blood flow and prolonged hyperaemia lasting up to 3 h. The hyperaemic response to 10(-13) mol of each peptide was significantly (P less than 0.01) smaller and shorter in duration than that elicited by 10(-11) mol of the same peptide, and 10(-15) mol of both peptides produced no hyperaemia other than that attributable to needle insertion alone. 3. At all three dosages examined, there were no significant differences between A- and B-calcitonin-gene-related peptides in magnitude or time course of the hyperaemic response. 4. Human A- and B-calcitonin-gene-related peptides are therefore potent vasodilators in man, causing comparable dose-related vasodilatation in the superficial tissues.

Abstract
Central and lateral hypothalamic concentrations of 10 regulatory peptides were measured by radioimmunoassay in streptozocin-induced diabetic (STZ-D) and matched control rats between 1 day and 14 wk after diabetes induction. After 2 wk, both central and lateral hypothalamic neuropeptide Y (NPY) concentrations in STZ-D rats were consistently higher than those found in control rats, with significant 30-50% increases at 4 wk in the central hypothalamus, and at 6 and 14 wk in both central and lateral hypothalamus. Immunocytochemical studies in 4- and 6-wk STZ-D animals showed the appearance of intensely NPY-positive swollen cell bodies in the supraoptic nucleus and a subjective increase in NPY staining of medial hypothalamic nerve fibers. Central hypothalamic concentrations of three other peptides were significantly greater in STZ-D animals than those in control animals at single points (neurotensin, 1 day; calcitonin gene-related peptide, 2 wk; neurokinin, 4 wk). Hypothalamic concentrations of the other six peptides examined (bombesin, galanin, neuromedin B, substance P, somatostatin, and vasoactive intestinal peptide) did not differ significantly between STZ-D and control groups at any time. However, galanin immunostaining in the supraoptic and magnocellular paraventricular nuclei was strikingly concentrated in a reduced number of distended cell bodies. Hypothalamic peptide changes in STZ-D could be related to metabolic disturbance, changes in energy and water balance, altered pituitary function, or other factors. Persistently elevated concentrations of NPY, a very potent central stimulant of eating and drinking, may mediate the hyperphagia and polydipsia characteristic of STZ-D.

Abstract
In the present paper we report a technique which permits the simultaneous observation of C-banded material and the active NORs or nucleoli in both mitotic and meiotic chromosomes of mammals and insects. The use of the present technique permits to establish a complete correlation between the C-banded positive regions and the presence of nucleoli associated to them. Some aspects related with this correspondence are discussed.

Abstract
The method described here has the advantage of presenting a clear image of both chromosomes and silver grains. Chromosomes are stained through the emulsion with Hoechst 33258. As two different sources of light are employed-epi-ultraviolet illumination and transmitted visible light-a separate photographic record of each optical plane can be obtained of chromosomes, silver grains, and chromosomes and grains together.

Abstract
Bilateral optic nerve hypoplasia affected five individuals corresponding to four generations of a family. Two decreased men were also apparently affected. The three patients studied, two women and a girl, presented the same clinical picture: poor visual acuity; small, pale and malformed papilla; two concentric peripapillary halos; and wandering movements of the eyes. Fluorescein angiography performed in the propositus mother showed a faint papillary fluorescence. At variance with the two familial cases reported, the pedigree clearly suggest an autosomal dominant type of inheritance. Similar clinical features found in other patients suggest a stationary nature of the defect.
