Orbital metastasis diagnosed by ultrasound-guided fine-needle aspiration biopsy: Case report of unknown primary site.

Twenty five percent of orbital metastasis is usually of unknown primary origin and it requires histopathological and immunohistochemical confirmation. The fine-needle aspiration biopsy of the orbit is an alternative procedure to conventional orbitotomy. The case is presented of a 60 year-old woman with a right orbit tumour mass and neoplastic lesions in her brain and cranium.

High frequency of the exoU+/exoS+ genotype associated with multidrug-resistant "high-risk clones" of Pseudomonas aeruginosa clinical isolates from Peruvian hospitals.

The type III secretion system of Pseudomonas aeruginosa is an important virulence factor contributing to the cytotoxicity and the invasion process of this microorganism. The current study aimed to determine the presence of the exoU+/exoS+ genotype in P. aeruginosa clinical isolates.

Health need assessment in an indigenous high-altitude population living on an island in Lake Titicaca, Perú.

Background: Health needs and access to health care is a huge challenge in developing countries, especially in some isolated indigenous communities. Amantani is an island located at 3854 m above sea level in Lake Titicaca, Peru. There is no official date on key local health needs and determinants, which precludes the prioritization and efficient implementation of health interventions.

[Jejunal phlebectasia as a cause of massive gastrointestinal haemorrhage].

Vascular abnormalities of the gastrointestinal tract are a common cause of gastrointestinal bleeding. Most of them are located within the reach of the upper endoscopy or colonoscopy, although once discarded, it forces to consider small bowel as the source of bleeding. The successful management of a gastrointestinal bleeding depends mainly on the timely location of the source of bleeding.

[Prevalence of histological types of gastric polyps in adult patients from a public hospital in Lima-Peru (2007 - 2016)].

Objectives: Establish the prevalence of gastric polyps detected by upper gastrointestinal endoscopy in patients older than 18 years old during the period from 2007 - 2016 in Cayetano Heredia Hospital.

Materials And Methods: Retrospective cross-sectional study, performed with data from the gastric biopsies reports of patients that have undergone upper gastrointestinal endoscopy between January 2007 and July 2016. Demographic data, endoscopic characteristics of the polyps and associated histological changes of the surrounding gastric mucosa were evaluated, which were subjected to statistical analysis using STATA v14.

[Severe asymptomatic iron deficiency anemia as an unusual presentation of a Meckel diverticulum].

Meckel's diverticulum is a rare clinical entity in clinical practice. However, it should be considered as an important differential diagnosis in patients with both obscure overt and occult gastrointestinal bleeding. Years ago, the evaluation of the small bowel was impossible without surgery, nowadays the development of new diagnostic methods has changed this horizon.

Identfication of viral and bacterial etiologic agents of the pertussis-like syndrome in children under 5 years old hospitalized.

Background: Acute respiratory infections (ARIs) represent an important cause of morbidity and mortality in children, remaining a major public health concern, especially affecting children under 5 years old from low-income countries. Unfortunately, information regarding their epidemiology is still limited in Peru.

Methods: A secondary data analysis was performed from a previous cross-sectional study conducted in children with a probable diagnosis of Pertussis from January 2010 to July 2012.

Increased Relative Abundance of Klebsiella pneumoniae Carbapenemase-producing Klebsiella pneumoniae Within the Gut Microbiota Is Associated With Risk of Bloodstream Infection in Long-term Acute Care Hospital Patients.

Background: An association between increased relative abundance of specific bacterial taxa in the intestinal microbiota and bacteremia has been reported in some high-risk patient populations.

[Self-Knowledge, Adherence to Treatment, and Control of Arterial Hypertension in Peru: a Narrative Review].

This non-systematic bibliographic review examines the published Peruvian medical literature on arterial hypertension (HTN) as of December 2016. The results were divided into three thematic areas: self-knowledge, adherence to treatment, and control. We identified 197 articles, although only 15 were used for the analysis.

Molecular etiological profile of atypical bacterial pathogens, viruses and coinfections among infants and children with community acquired pneumonia admitted to a national hospital in Lima, Peru.

Objective: The main objective of this study was to detect the presence of 14 respiratory viruses and atypical bacteria (Mycoplasma pneumoniae, Chlamydia pneumoniae), via polymerase chain reaction in patients under 18 years old hospitalized due to community-acquired pneumonia (CAP) from Lima, Peru.

Results: Atypical pathogens were detected in 40% (58/146); viral etiologies in 36% (52/146) and coinfections in 19% (27/146). The most common etiological agent was M.

[Duodenal Linphoma asociated to Strongyloides stercoralis infection. Two types of HTLV-1 infection].

Infection by the Human T- Lymphotropic virus I (HTLV-1) causes Adult T cell Leukemia-lymphoma (ATLL), being the duodenal involvement rare. Commonly, patients co-infected with HTLV-1 and Strongyloides stercoralis are seen due to the lack of TH2 response found on these patients. We describe a 48-year- old woman, from the jungle of Peru, with a family history of HTLV-1 infection, who presented with a History of chronic diarrhea and weight loss.

A decade of HAART in Latin America: Long term outcomes among the first wave of HIV patients to receive combination therapy.
