Abstract
INTRODUCTION Congenital esophageal stenosis (CES) is an extremely rare pathology in children, with an incidence of 1/25,000-50,000 live births. According to its histopathological classification, there are three types of CES: fibromuscular hyperplasia, membranous diaphragm, and tracheobronchial remnants. CLINICAL CASE We present the clinical case of a 39-month-old male patient diagnosed with CES secondary to tracheobronchial remnants, with multiple vomit and reflux episodes since he was 4 months old. He was admitted at the emergency department with respiratory distress. An upper GI endoscopy and an esophagogram were initially carried out. Stenosis resection and thoracoscopic esophageal anastomosis were performed. CONCLUSIONS Tracheobronchial remnants are the second most common presentation of congenital esophageal stenosis. They can be managed through dilatations or surgery according to etiology.

Abstract
AIM To describe the factors that are associated with gadolinium enhancement on MRI in patients with multiple sclerosis (MS) and symptoms of relapse. PATIENTS AND METHODS A retrospective cross-sectional study of patients over 18 years diagnosed with relapsing-remitting MS, secondary progressive and primary progressive from 2009 to 2014, who had a clinical relapse and underwent brain and spinal resonance with gadolinium during the acute phase of the symptoms. RESULTS Of the 93 patients enrolled, 70% were women, the average age was 37 ± 9.6 years. 90% had relapsing-remitting MS and 50% had at least 5 years since the diagnosis. The 56% had medullar involvement, being the most frequent sensory disturbances (44%). The median duration of symptoms was 6 days (range: 1-89 days). The 93% required treatment with intravenous methylprednisolone 3-5 days, which was administered after performing MRI studies. No evidence statistical difference in the presence of lesions that gadolinium enhancement on MRI during relapse with any of the clinical variables analyzed and only a tendency was observed with associated symptoms (p = 0.07). CONCLUSIONS The definition of relapse MS is clinic. However, the enhancement of the MRI in the phase of relapse could be useful to confirm the disease's activity. With this information, could be a useful point on the treatment of these patients with immunomodulatory drugs.

Abstract
AIM To identify impairment in functional capacity associated with complicated and non-complicated diabetes using the 6-min walk distance test. METHODS We enrolled 111 adults, aged ≥40 years, with Type 2 diabetes from a hospital facility and 150 healthy control subjects of similar age and sex from a community site in Lima, Peru. All participants completed a 6-min walk test. RESULTS The mean age of the 261 participants was 58.3 years, and 43.3% were male. Among those with diabetes, 67 (60%) had non-complicated diabetes and 44 (40%) had complications such as peripheral neuropathy, retinopathy or nephropathy. The mean unadjusted 6-min walk distances were 376 m and 394 m in adults with and without diabetes complications, respectively, vs 469 m in control subjects (P<0.001). In multivariable regression, the subjects with diabetes complications walked 84 m less far (95% CI -104 to -63 m) and those without complications walked 60 m less far (-77 to -42 m) than did control subjects. When using HbA1c level as a covariate in multivariable regression, participants walked 13 m less far (-16.9 to -9.9 m) for each % increase in HbA1c . CONCLUSIONS The subjects with diabetes had lower functional capacity compared with healthy control subjects with similar characteristics. Differences in 6-min walk distance were even apparent in the subjects without diabetes complications. Potential mechanisms that could explain this finding are early cardiovascular disease or deconditioning.

Abstract
The development of speech perception relies upon early auditory capacities (i.e. discrimination, segmentation and representation). Infants are able to discriminate most of the phonetic contrasts occurring in natural languages, and at the end of the first year, this universal ability starts to narrow down to the contrasts used in the environmental language. During the second year, this specialization is characterized by the development of comprehension, lexical organization and word production. That process appears now as the result of multiple interactions between perceptual, cognitive and social developing abilities. Distinct factors like word acquisition, sensitivity to the statistical properties of the input, or even the nature of the social interactions, might play a role at one time or another during the acquisition of phonological patterns. Experience with the native language is necessary for phonetic segments to be functional units of perception and for speech sound representations (words, syllables) to be more specified and phonetically organized. This evolution goes on beyond 24 months of age in a learning context characterized from the early stages by the interaction with other developing (linguistic and non-linguistic) capacities.

Abstract
INTRODUCTION AND OBJECTIVES Minimising false positives rates is an important goal of universal newborn hearing screening programmes. An adequate way for reaching that goal could be differentiating between transient conductive hearing losses (false positives) and permanent sensorineural hearing impairments (true positives) by means of a methodology that studies electrophysiological responses obtained using both air- and bone-conduction stimuli. Our objective was to evaluate the efficiency of an automated hearing screening test based on auditory steady state responses obtained using simultaneous air- and bone-conduction stimuli. METHODS A sample of 80 high risk babies lees than 2 months of born were screened using the automatic screening test. A confirmatory clinical and electrophysiological evaluation was used as the gold standard. RESULTS The estimated diagnostic efficiency of this screening test was equivalent (100% sensitivity and 97.7% specificity) to the efficiency reported for otoacoustic emissions and automated auditory brainstem responses. The introduction of bone conduction in the screening reduced the false positive rate from 13.3% to 2.2%. The test duration was 5.3 (± 1.9)min. In 34% of babies only one repetition of the test was needed to raising the result. CONCLUSIONS The screening test performed quite well in this initial clinical trial, differentiating transient conductive hearing losses from permanent neurosensory impairments and improving the diagnostic efficiency of auditory steady state responses.

Abstract
Admixture occurs when individuals from parental populations that have been isolated for hundreds of generations form a new hybrid population. Currently, interest in measuring biogeographic ancestry has spread from anthropology to forensic sciences, direct-to-consumers personal genomics, and civil rights issues of minorities, and it is critical for genetic epidemiology studies of admixed populations. Markers with highly differentiated frequencies among human populations are informative of ancestry and are called ancestry informative markers (AIMs). For tri-hybrid Latin American populations, ancestry information is required for Africans, Europeans and Native Americans. We developed two multiplex panels of AIMs (for 14 SNPs) to be genotyped by two mini-sequencing reactions, suitable for investigators of medium-small laboratories to estimate admixture of Latin American populations. We tested the performance of these AIMs by comparing results obtained with our 14 AIMs with those obtained using 108 AIMs genotyped in the same individuals, for which DNA samples is available for other investigators. We emphasize that this type of comparison should be made when new admixture/population structure panels are developed. At the population level, our 14 AIMs were useful to estimate European admixture, though they overestimated African admixture and underestimated Native American admixture. Combined with more AIMs, our panel could be used to infer individual admixture. We used our panel to infer the pattern of admixture in two urban populations (Montes Claros and Manhuaçu) of the State of Minas Gerais (southeastern Brazil), obtaining a snapshot of their genetic structure in the context of their demographic history.

Abstract
A cave (102 m long) under the structure of the Sun pyramid of the prehispanic Teotihuacan City indicates the importance of the pyramid. Studies of the cave mortar samples using energy dispersive X-ray (EDX) fluorescence, scanning electron microscopy (SEM) and X-ray diffraction (XRD) showed no difference in the chemical elemental composition. The elements can be distributed in three groups: major, minor and trace elements. The minerals identified were compatible with the origins of the cave and with the magnetic pattern.

Abstract
The stability studies of tablets containing 5 mg of policosanol, a new cholesterol lowering drug, were conducted to predict an expiration date and to search the appearance of putative degradation products. All quality parameters such as colour, moisture content, hardness, disintegration, policosanol content and microbiological limits of the tablets were assessed. The effect of extreme treatments such as acid and basic hydrolysis, oxidative and photolytic degradation as well as thermal degradation, on the policosanol content was studied. In addition, studies under extreme conditions of storage [(40 +/- 2) degree C and (75 +/- 5)% R.H.] as well as 37, 45, 55 and 60 degrees C combined with 50, 75 and 92% R.H.) and under ambient conditions of storage for climatic zones II and IV were performed. These studies demonstrate that these tablets are a stable pharmaceutical formulation, without significant changes in their quality criteria at the stressed conditions used, so that policosanol content remains unchanged during the entire studies. The chromatographic profile of the samples after 9 months of thermal degradation shows chromatographic peaks that corresponds to the palmitate and stearate esters of octacosanoyl, triacontanoyl and hexacosanoyl, being the only degradation products observed on these studies.

Abstract
An epidemiological study was conducted in a highland, rural community in Peru, to determine the seroprevalences of human and porcine infection with Taenia solium and the risk factors associated with human infection. The seroprevalences, determined using an assay based on enzyme-linked-immuno-electrotransfer blots (EITB), were 21% (66/316) in the humans and 65% (32/49) in the pigs. The human subjects aged <30 years were more likely to be positive for anti-T. solium antibodies than the older subjects (P < 0.001). The risk factors associated with human seropositivity were lack of education beyond the elementary level [odds ratio (OR)=2.69; 95% confidence interval (CI)=1.09-6.65] and pig-raising (OR=1.68; CI=0.96-2.92). Curiously, sheep-raising was inversely associated with human T. solium infection (OR=0.50; CI=0.28-0.90). The study site appears to be a new endemic focus for T. solium in the central Peruvian Andes. Although, in earlier studies, the seroprevalence of T. solium infection has generally been found to increase with age, the opposite trend was observed in the present study. The results of follow-up studies should help determine if the relatively high seroprevalence in the young subjects of the present study is the result of a transient antibody response.

Abstract
Policosanol is an active principle, composed by 8 fatty alcohols: 1tetracosanol, 1-hexacosanol, 1-heptacosanol, 1-octacosanol, 1-nonacosanol, 1-triacontanol, 1-dotriacontanol and 1-tetratriacontanol that shows a very stable, well defined and reproducible composition from batch to batch that is analysed using gas chromatography. Continuing the studies of the compatibility among policosanol and different tablet excipients, it was studied if the mixtures of those excipients with policosanol produce chemical interactions between them, the samples were analysed using gas chromatography and was determined if it was affected the content of policosanol in them. When all the samples were analysed, no changes in the policosanol content of the samples were observed, and it was considered that no interactions are produced in any of the mixtures policosanol/excipients under study.

Abstract
BACKGROUND Cohort and case-crossover studies were conducted to evaluate whether new Helicobacter pylori infections are followed by increased diarrhea. METHODS Participants were 6-month-old to 12-year-old shantytown residents living near Lima, Peru. Baseline data were collected from community households. Health interviews were completed daily, and sera, drawn every 4 months, were tested for H pylori immunoglobulin G. Diarrhea rates among newly H pylori-infected (seroconverting) children were compared with rates among persistently uninfected and infected children using cohort and case-crossover analyses. RESULTS Sera were obtained from 345 children from January 1, 1995, through September 1, 1997. H pylori incidence was 12% per year (36 H pylori infections in 109 866 seronegative days). In adjusted cohort analyses, seroconverters had more diarrhea days (rate ratio: 2.0; 95% confidence interval: 1.6-2.4), episodes, and sick days in the year after infection than did uninfected children; and more diarrhea days and sick days than did persistently infected children. This effect was strongest in the first 2 months. Case-crossover analyses supported these findings. CONCLUSION Preventing H pylori infection may help reduce pediatric diarrheal disease.

Abstract
BACKGROUND Non-steroidal antiinflammatory drugs (NSAIDs) produce severe gastrointestinal (G-I) complications in 1-4% of cases which need to be treated into the hospital. The aim of this study has been to assess the hospital cost secondary to treat these complications in our National Health Service (NHS). MATERIAL AND METHODS In the first phase a cross-sectional study was performed in order to know the number of patients who were hospitalized due to a severe G-I complication during 1998 in two tertiary hospital in our country. It was reviewed their clinical charts to know whether they had taken any NSAIDs. In those positive cases all resources used during the hospitalization were collected. RESULTS In both hospitals studied 38.1% of hospitalized patients for a severe G-I complication had taken any NSAIDs during the same day or previous days. The cost/patient was of 389,831 pesetas. During 1998 in the whole NHS there were 54,623 hospitalizations owing to the same reason. Assuming that 38.1% of them had also taken any NSAIDs, 20,811 patients would have suffered a severe G-I complication potentially due to the intake of NSAIDs. Extrapolating the cost/patient obtained in both hospitals to the global number of patients hospitalized into the NHS, the cost of treating all severe G-I complications related to the consumption of NSAIDs during 1998 was of 8,112 millions pesetas. CONCLUSIONS Bearing in mind the elevated prevalence of osteo-articular pathology in our country and the high consumption of NSAIDs for its treatment, the coming of new therapeutic options with a better safety profile would mean an important resources' saving for our NHS.

Abstract
The Helicobacter pylori stool antigen enzyme immunoassay (HpSA) was evaluated during posttreatment follow-up of patients in a country with a very high prevalence of H. pylori infection. From among 273 dyspeptic individuals (18 to 55 years) initially recruited from a shantytown in Lima, Peru, 238 participants who met the inclusion criteria and were suspected to be H. pylori positive based on (14)C urea breath test (UBT) results underwent endoscopy. Participants with endoscopy-proven infections received standard eradication therapy and were monitored by UBT and HpSA at 1 month following treatment and at 3-month intervals for 9 months posttreatment. A second endoscopy was performed if UBT results showed evidence of treatment failure or H. pylori recurrence. Biopsy results were considered the "gold standard" in all analyses. Among patients who underwent endoscopy, HpSA had a pretreatment sensitivity of 93%. Two-hundred thirty patients completed the treatment regimen, of whom 201 (93%) were considered to have had successful treatment outcomes based on a negative follow-up UBT. Thirty-two patients with UBT-defined treatment failures or H. pylori recurrences at any point during the 9-month follow-up underwent a second endoscopy. In the posttreatment setting, HpSA had an overall sensitivity of 73% and a specificity of 67%. Agreement between UBT and HpSA diminished throughout the follow-up. Among 14 participants in whom HpSA remained positive at 1 month following treatment despite UBT evidence of treatment success, 12 (86%) became HpSA negative within 3 months posttreatment. Although this study confirmed the validity of the HpSA in the initial assessment of dyspeptic patients, the test demonstrated a reduced overall accuracy in the detection of treatment failures and H. pylori recurrences during 9 months of posttreatment follow-up. Furthermore, in some patients it may take up to 3 months after successful eradication for antigen shedding to diminish to levels within the negative HpSA range.

Abstract
BACKGROUND Non-steroid anti-inflammatory drugs (NSAIDs) can produce haemorrhages of the digestive tract, whose treatment result in significant hospital costs. OBJECTIVE The aim of this analysis has been to estimate hospital costs related to the treatment of digestive haemorrhages potentially caused by the intake of NSAIDs. MATERIAL AND METHODS The study was conducted by reviewing the clinical history of all patients admitted in two tertiary Spanish hospitals during 1998 due to digestive haemorrhage following NSAID treatment. After the identification of cases, all resources consumed during their hospitalisation (concomitant medication, complementary examinations and tests, surgery, blood products consumption, inpatient consultations and length of stay in the hospital) until the complete resolution of each case, were recorded. RESULTS Thirty-six percent of patients admitted due to digestive haemorrhage had taken some NSAID the same day of their hospitalisation (85.4%) or in previous days. The cost related to the treatment of these patients amounted to some 71 million pesetas for both hospitals, with a cost/patient of 434,407 pesetas. CONCLUSIONS Given the high consumption of NSAIDs in our normal clinical setting, costs related to the diagnosis and treatment of digestive haemorrhages in hospitals are a highly significant burden for the National Health System.

Abstract
Cryptosporidium parvum is usually considered to be the pathogen responsible for human cryptosporidiosis. We genotyped Cryptosporidium in 132 stool specimens from 80 Peruvian children, representing 85 infection episodes, using techniques that differentiate Cryptosporidium species and C. parvum genotypes. Five types of Cryptosporidium were identified: C. parvum human (67), bovine (8), and dog (2) genotypes, C. meleagridis (7), and C. felis (1). Twenty-five (29%) of the 85 infection episodes were associated with diarrhea. There was no significant difference in age, antecedent stunting, percentage with diarrhea, or duration of diarrhea for episodes with human genotype, compared with those of zoonotic Cryptosporidium. Duration of oocyst shedding was longer for human genotype than for zoonotic Cryptosporidium (mean, 13.9 days and 6.4 days, respectively; P=.004). Serum samples from 8 children with C. meleagridis, C. felis, or C. parvum dog genotype were tested for anti-human immunodeficiency virus (HIV) type 1 antibodies; all were found to be negative. Contrary to common belief, novel Cryptosporidium species and C. parvum genotypes can infect HIV-negative children.

Abstract
In this work, we report on a relationship between urinary selenium and the development of cervical uterine cancer. A simple chemical method was developed to concentrate trace amounts of selenium from relatively large urine samples by use of small activated carbon filters. When these filters are irradiated with thermal neutrons, selenium can be determined either by 77mSe (t1/2 = 17.5 s) or 75Se (t1/2 = 120 d). In this article, we report the results for 82 urine samples from women with cervical uterine cancer in several stages of development and from healthy controls. These results show a statistically significant increase of selenium excretion in cancer patients as compared to controls. Urinary selenium excretion is highest for patients in the intermediate stages of the disease.

Abstract
OBJECTIVE To describe the case of a patient with familial adenomatous polyposis (FAP) who developed organic hyperinsulinemia and hypoglycemia due to pancreatic nesidioblastosis. BACKGROUND FAP can be considered as one of the familial cancer syndromes. The development of endocrine tumors in these patients is an infrequent event, and most of these tumors have been well-differentiated thyroid neoplasms. To our knowledge, the occurrence of organic hyperinsulinemia in the context of FAP has not been reported. METHODS Organic hyperinsulinemia was demonstrated during a 72-h fast, measuring insulin and C-peptide by RIA at the time of hypoglycemia. Immunohistochemistry for insulin and other pancreatic hormones was performed on the surgical pancreatic specimen. RESULTS The patient underwent a distal pancreatectomy with resolution of hypoglycemia. Histopathologically, the excised pancreas showed beta cell hyperplasia arising from the ductal epithelium. Such beta cells strongly immunostained for insulin, pancreatic polypeptide, and neuron-specific enolase. CONCLUSIONS The development of endocrine tumors in an inherited cancer syndromes such as FAP is rare. Such an association may suggest shared mechanisms of tumorigenesis. The case herein reported should prompt us to consider organic hyperinsulinism as an extracolonic manifestation of FAP.

Abstract
An investigation was performed after an outbreak of bartonellosis in a region of Peru nonendemic for this disorder. Symptoms of acute and chronic bartonellosis were recorded. Serological analysis was performed on 55% of the affected population (554 individuals), 77.5% of whom demonstrated previous infection with Bartonella bacilliformis. The attack rate of Oroya fever was 13.8% (123 cases); the case-fatality rate was 0.7%. The attack rate of verruga peruana was 17.6%. A new specific immunostain was developed and used to confirm the presence of B. bacilliformis in the biopsied skin lesions. Most seropositive individuals (56%) were asymptomatic. The symptoms that were associated with prior infection, as determined by Western blot, included fever (37.2% of the seropositive vs. 17.2% of the seronegative population; P<.001), bone and joint pain (27% vs. 9%; P<.001), headache (27% vs. 12.3%; P <.001), and skin lesions described as verruga peruana (26.8% vs. 4.9%; P<.001). Our findings suggest that infection with B. bacilliformis causes a broad spectrum of disease that is significantly milder in severity than that frequently reported.

Abstract
BACKGROUND Acquisition of Helicobacter pylori infection occurs mainly during childhood. To study the events associated with H. pylori colonization in children it is important to have reliable diagnostic methods. Our objective was to validate invasive and noninvasive tests for diagnosis of H. pylori infection in children before and after antimicrobial treatment. METHODS Before treatment, invasive rapid urease test (RUT) culture and histology, as well as the noninvasive carbon-13 urea breath test (13C-UBT) and serology were validated in 59 children. The gold standard for H. pylori infection was any of three positives of the five tests. After antimicrobial treatment culture, histology, and 13C-UBT were validated in 43 children to determine eradication. The gold standard for eradication was negative in all three tests. RESULTS For primary diagnosis, RUT was the most sensitive and specific test, followed by 13C-UBT, which performed better than serology, culture, and histology. Concordance tests also showed that RUT and 13C-UBT performed better. For determination of eradication, 13C-UBT and histology were better than culture, which showed poor sensitivity. CONCLUSIONS RUT performed better for primary diagnosis. However, as endoscopy might not be indicated in most children, 13C-UBT could be the test of choice for diagnosis of H. pylori infection both before and after eradication treatment.

Abstract
BACKGROUND In a previous study, we found that gallstones were a common occurrence in the high altitude villages of the Peruvian Andes. AIMS To determine if high altitude (> or = 1500 m) is a contributing risk factor for gallstone disease. METHODS We conducted a cross sectional study in a periurban community in Lima, Peru, and compared the prevalence of gallstone disease between coastal natives, highland (Sierra) natives and Sierra natives who had migrated to the coast. We also compared the prevalence rates from this study with those from a previous study conducted at high altitude. We examined 1534 subjects >15 years of age for gallstone disease. Subjects were interviewed for the presence or absence of risk factors. RESULTS Gallstone disease was more common in females (16.1 cases per 100, 95% CI 13.8-18.2) than in males (10.7 per 100, 95% CI 8.0-13.4). Females had a greater risk of gallstone disease, especially if they had used oral contraception and/or had four or more children. The age adjusted prevalence was not significantly different between coastal natives, Sierra migrants, and Andean villagers. The prevalence of gallstone disease was not associated with time since migration or with having native Sierra parents. After adjusting for other risk factors, Sierra natives who migrated to the coast had a lower prevalence of gallstone disease than coastal natives (odds ratio 0.74, 95% CI 0.58-0.94). CONCLUSIONS This study indicates that high altitude is not a positive risk factor for gallstone disease and confirms that this disease is common in Peruvians, which may be attributable to Peruvian-Indian ethnicity.

Abstract
Human, canine and ovine echinococcosis prevalence was determined in a highland community located in the central Peruvian Andes during 1997 and 1998. Human echinococcosis was determined using portable ultrasonography, chest X-ray examination, and an enzyme-linked immunoelectrotransfer blot (EITB) assay. Canine echinococcosis was determined using microscopy stool examinations and a coproantigen detection enzyme-immunoassay (EIA) for Echinococcus granulosus. Ovine echinococcosis was determined by an EITB assay for sheep echinococcosis and necropsy examination of viscera from domestic slaughtered animals. An abdominal ultrasound, a chest X-ray examination and an EITB for echinococcosis were performed on 214 subjects (45% of the village population). The frequency of presumptive liver/abdominal, lung and liver-lung hydatid cysts was 5.1% (11/214), 3.7% (8/214) and 0.5% (1/214), respectively. The overall prevalence of human cystic echinococcosis was 9.3% (20/214). The frequency of canine echinococcosis was 46% (23/50) and 32% (16/50) by the coproantigen EIA test and arecoline purging, respectively. The frequency of sheep echinococcosis was 65% (22/34) by the EITB and 38% (13/34) by necropsy. We demonstrated a high prevalence of human and animal echinococcosis in this Peruvian village. In remote areas where echinococcosis is endemic, both the coproantigen EIA and arecoline purging may be used for the study of canine echinococcosis; the EITB is useful in establishing the diagnosis of echinococcosis in sheep prior to necropsy.

Abstract
OBJECTIVE Lactobacillus GG (L-GG), an acid- and bile-resistant strain that colonizes the intestinal mucosa, has been used to manage diarrhea in children. Our objective was to evaluate the prophylactic use of L-GG to prevent diarrhea in children at high risk from a developing country in a randomized, placebo-controlled trial. STUDY DESIGN Two hundred four undernourished children 6 to 24 months old from an indigent peri-urban Peruvian town received either L-GG or placebo in flavored gelatin once daily, 6 days a week, for 15 months. Episodes of diarrhea were documented by daily home visits, and diagnostic studies were done in a subset of cases. Recovery of L-GG in stool from subjects and from family contacts was examined. RESULTS Subjects in the L-GG group had significantly fewer episodes of diarrhea (5.21 episodes diarrhea/child/year ['ecy'] L-GG group, 6. 02 ecy placebo group; P =.028). The decreased incidence of diarrhea in the L-GG group was greatest in the 18- to 29-month age group (P =. 004) and was largely limited to nonbreastfed children (Breastfed: 6. 59 ecy L-GG, 6.32 ecy placebo, P =.7; Nonbreastfed: 4.69 ecy L-GG, 5. 86 ecy placebo, P =.005). The duration of diarrhea episodes and the causes of diarrhea were similar in both groups, except adenovirus was more common in the placebo group. CONCLUSION L-GG supplementation may be useful as a prophylactic measure to control diarrhea in undernourished children at increased risk, especially nonbreastfed children in the toddler age group.
