Background: Previously reported outcomes after tendon transfers to reconstruct the subscapularis are unpredictable and often unsatisfactory, especially in the presence of anterior humeral head subluxation. We studied the anatomic feasibility of the lower trapezius and the rhomboid minor transfer to reconstruct irreparable tendon tears of the subscapularis. The aim of this study was to determine the feasibility of lower trapezius and rhomboid minor transfer to reconstruct irreparable subscapularis tendon tears.

Yeasts, commonly present on the surface of fruits, are of industrial interest for the production of enzymes, flavorings, and bioactive compounds, and have many other scientific uses. The Amazonian rainforest may be a good source of new species or strains of yeasts, but their presence on Amazonian fruits is unknown. The aim of this study was to identify and characterize yeasts isolated from Amazonian native fruits using molecular and phenotypic methods.

The frequency of celiac disease (CD) has increased along time, with relevant changes reported in geographical variations, clinical presentation and nutritional repercussions. In recent years, some celiac patients are presenting overweight/obesity, but it is unclear how frequent this is and to what extent undernutrition remains a concern. This is relevant because CD tends to be overlooked in overweight patients.

Background: The objective of the present histologic animal study was to analyze whether roughness of the titanium surface can influence and/or stimulate the bone growth in defects filled with the blood using a rabbit tibia model.

Materials And Methods: Forty sets (implant and abutment), dental implant (3.5 mm in diameter and 7 mm in length) plus healing abutment (2.

Mueller-Weiss disease is an alteration of the tarsal navicular that is primarily due to anomalous ossification of the bone and lateral deviation of the talar head associated with screw-like movement through the axis of the subtalar joint. This syndrome tends to be associated with various degrees of flatfoot and hindfoot valgus combined with subtalar joint varus. Ancient cases of Mueller-Weiss disease have not been described in specialized literature.

Deltoid palsy is a classical contraindication for reverse shoulder arthroplasty (RSA). However, in cases associating axillary nerve palsy and rotator cuff tear or glenohumeral arthritis, few options remain. We present a case in which combining RSA with transfer of the pectoralis major and upper and middle trapezius transfer provided satisfactory results in a patient suffering of both an irreparable rotator cuff tear and a deltoid palsy.

Background: Current reports applying ESPGHAN exception criteria (EEC) to diagnose celiac disease (CD) without duodenal biopsies indicate that a high percentage of patients with CD may be identified when applied correctly in specialized settings. Application of the EEC, however, in "daily life conditions" at the different levels of medical services is not clear.

Methods: EEC was applied to 130 pediatric patients evaluated for CD at 5 public hospitals in Santiago, Chile, during 2010 to 2015.

This work investigates whether a submarine volcanic eruption off El Hierro (Canary Islands) in October 2011 influenced the metal contents of two deep water cephalopod species: Abraliopsis morisii and Pyroteuthis margaritifera. This was assessed by comparing metal contents in specimens collected off the island of El Hierro and in the neighbouring islands of La Palma and Tenerife during an experimental deep water fishing trip. The concentration of 20 heavy metals was analyzed in 180 specimens of A.

Capsular polysaccharides (CPSs) play multiple roles in protecting bacteria from host and environmental factors, and many commensal bacteria can produce multiple capsule types. To better understand the roles of different CPSs in competitive intestinal colonization, we individually expressed the eight different capsules of the human gut symbiont Bacteroides thetaiotaomicron. Certain CPSs were most advantageous in vivo, and increased anti-CPS immunoglobulin A correlated with increased fitness of a strain expressing one particular capsule, CPS5, suggesting that it promotes avoidance of adaptive immunity.

Setting: In 2012, Peru's National TB Program (NTP) reported approximately 2400 incident cases of tuberculosis (TB) disease in children aged <15 years. Peru's TB burden is concentrated in the Lima metropolitan area, particularly in poor districts such as El Agustino and La Victoria, where this study was conducted.

Objective: To identify barriers to the treatment of childhood tuberculous infection and TB disease in Lima from the perspective of front-line providers and patients' families.

Neuromyelitis optica (NMO) is a severe demyelinating disease of the central nervous system, which preferentially attacks the optic nerve and spinal cord. It is associated with antibodies against aquaporin 4. Morbidity and mortality are higher than in multiple sclerosis and its treatment focuses on immunosuppressive drugs.

Objective: The extent of the digestive/absorptive involvement in atypical presentation of celiac disease (CD) is not always clear. The aim of the study was to assess nutritional status of iron (Fe), copper (Cu), and zinc (Zn) in patients with typical CD (TCD) and atypical CD (ACD).

Patients And Methods: A cross-sectional study was done in patients with TCD, ACD, and healthy controls (HC).

Background And Objective: Risk haplotypes have been described in celiac disease (CD), but the influence of native genes on CD in Hispanic Americans is unknown. The aim of the study was to measure the frequency of Amerindian mitochondrial DNA (mtDNA) haplogroups (inherited by the maternal line) in mixed-blood patients with CD from Chile, Argentina, and Uruguay, and to assess the relation between these and human leukocyte antigen (HLA) alleles and haplotypes and clinical presentations.

Patients And Methods: Clinical history, histological data, and genetic studies were conducted following 2 protocols: a case-control study of 72 Chilean patients with CD and controls, and an assessment of 43 (additional) samples of celiac patients from Chile, 96 from Argentina, and 57 from Uruguay, compared with the mtDNA frequency in the corresponding country.

Leuconostoc is a gram-positive cocci, quite ubiquitous in nature. It is used in wine industry, and for aroma and texture of dairy products. Occasionally it has been isolated from humans in cases of bacteremia, catheter associated infections, sepsis, meningitis, pneumonia, UTI, osteomyelitis and hepatic dysfunction.

Background: There is a well-documented relationship between epilepsy and celiac disease, including a syndrome characterized by epilepsy, occipital calcifications, and celiac disease.

Review Summary: We report the case of a 23-year-old woman with an 11-year history of refractory epileptic seizures and newly diagnosed biopsy-proven celiac disease with increased antiendomysium immunoglobulin A antibodies. The patient showed a dramatic improvement after starting a gluten-free diet.

The effects of psychiatric pharmacy services on clinical outcomes of acute care psychiatric inpatients were studied. Patients recruited at a state psychiatric facility during phase 1 (October 1996-March 1997) served as the control group and received only traditional centralized pharmaceutical services and physician-requested psychiatric pharmacotherapy consultations. Patients recruited during phase 2 (May-December 1997) received intensive psychiatric pharmacy services and served as the experimental group.

A scoring instrument to detect unwanted newborns was applied to 556 living-in women at a Santiago urban hospital in december 1987. Based upon previous research a scoring instrument including 10 items was designed and applied within 24 hours following delivery. According to the total score each newborn was classified as wanted (W), unwanted (U) or doubtful situation: 37.

The antioxidant capacity of desferrioxamine (DF) was investigated in three biological systems. The addition of DF to rat brain homogenates undergoing autoxidation elicited a concentration dependent inhibition of both oxygen uptake and chemiluminescence, with a median inhibitory concentration (IC50) of 0.52 microM.
