INTRODUCTION: Rocky Mountain spotted fever is a highly lethal infectious disease, particularly if specific treatment with doxycycline is given belatedly. OBJECTIVE: To describe the clinical profile of fatal Rocky Mountain spotted fever cases in hospitalized patients in the state of Sonora, México. MATERIALS AND METHODS: We conducted a cross-sectional study on a series of 47 deaths caused by Rickettsia rickettsii from 2013 to 2016. The diagnosis of Rocky Mountain spotted fever was confirmed in a single blood sample by polymerase chain reaction (PCR) or by a four-fold increase in immunoglobulin G measured in paired samples analyzed by indirect immunofluorescence...

PURPOSE: Pyogenic spondylodiscitis (PS) is a potentially life-threatening infection burdened by high morbidity rates. Despite the rising incidence, the proper management of PS is still controversial. Aim of this study was to describe the clinical features of PS and to evaluate the prognostic factors and the long-term outcomes of a large population of patients. METHODS: 207 cases of PS treated from 2008 to 2016 with a 2-year follow-up were enrolled. Clinical data from each patient were recorded...

Schinzel-Giedion syndrome (SGS) is a rare autosomal dominant inheritance disorder. Heterozygous de novo mutations in the SETBP1 gene have been identified as the genetic cause of SGS. Here, we report a novel case with the syndrome with a novel insertion mutation in SETBP1. We also present a review of SGS cases, and first revise diagnostic criteria of SGS based on clinicalfindings and/or SETBP1 mutation worldwide. A revised diagnostic criteria and typing of SGS can be determined. Type I (complex and classic type) SGS patients present a development delay and typical facial features (prominent forehead, midface retraction, and short and upturned nose) associated with hydronephrosis or two of the characteristic skeletal anomalies (a sclerotic skull base, wideoccipital synchondrosis, increased cortical density or thickness, and broad ribs)...

It has long been recognized that female sex is associated with a lower risk of and improved survival in melanoma (Joosse et al., 2012). However, the mechanism underlying this disparity in outcomes is not understood. One potential explanation is behavioral- i.e. differences by sex in UV exposure, screening and detection, and healthcare utilization. Observed differences between men and women in prognostic factors in primary melanomas would support this. For example, men are more likely to have thicker, ulcerated tumors, which could reflect diagnostic delays...

BACKGROUND: Restorative proctocolectomy with IPAA improves quality of life in patients with medically refractory ulcerative colitis. Although bowel obstruction is common, pouch volvulus is rare and described only in case reports. Diagnosis can be challenging, resulting in delayed care and heightened morbidity. OBJECTIVE: The purpose of this study was to delineate the symptoms and successful management strategies used in patients with IPAA volvulus that result in pouch salvage...

Recent advances in materials chemistry establish the foundations for unusual classes of electronic systems, characterized by their ability to fully or partially dissolve, disintegrate, or otherwise physically or chemically decompose in a controlled fashion after some defined period of stable operation. Such types of "transient" technologies may enable consumer gadgets that minimize waste streams associated with disposal, implantable sensors that disappear harmlessly in the body, and hardware-secure platforms that prevent unwanted recovery of sensitive data...

Objectives: to assess the diagnostic accuracy of quantitative parameters of DCE-MRI in multi-parametric MRI (mpMRI) in comparison to the histopathology (including Gleason grade) of prostate cancer. Patients and methods: 150 men with suspected prostate cancer (abnormal digital rectum examination and or elevated prostate-specific antigen) received pre-biopsy 3T mpMRI and were recruited into peer-reviewed, protocol-based prospective study. The DCE-MRI quantitative parameters ( Ktrans (influx transfer constant) and kep (efflux rate constant)) of the cancerous and normal areas were recorded using four different kinetic models employing Olea Sphere (Olea Medical, La Ciotat, France)...

Obesity is linked with more aggressive prostate cancer and higher rates of disease recurrence post treatment. It is unclear if this is due to specific tumor-promoting effects of obesity or diagnostic bias. Patients undergoing prostatectomy were categorized according to their body mass index (BMI). Expected prostate-specific antigen (PSA) levels were calculated for each patient based on tumor characteristics. The effect of obesity on the accuracy of pre-treatment risk categorization was determined, and mediation analysis was used to identify the contribution of biologic vs non-biologic mechanisms to the observed increased risk of biochemical recurrence...

OBJECTIVE: Delayed cerebral ischemia (DCI) is a common, disabling complication of subarachnoid hemorrhage (SAH). Preventing DCI is a key focus of neurocritical care, but interventions carry risk and cannot be applied indiscriminately. While retrospective studies have identified continuous EEG (cEEG) measures associated with DCI, no study has characterized the accuracy of cEEG with sufficient rigor to justify using it to triage patients to interventions or clinical trials. We therefore prospectively assessed the accuracy of cEEG for predicting DCI, following the Standards for Reporting Diagnostic Accuracy Studies...

Flexible endoscopy has developed from a diagnostic tool for tissue biopsy sampling to a treatment tool for endoscopic resection of neoplasms in the digestive tract. In the near future, one of the advanced endoscopic techniques, endoscopic full-thickness resection (EFTR), is expected to be a feasible endoscopic procedure. In the present review, systematic review of conventional exposed EFTR was carried out. Search queries were (endoscopic full-thickness resection or EFTR) (over-the-scope clip or OTSC) (Overstitch System) from 2015 to 2017...

Background: Acute Type A aortic dissection (ATAAD) without end-organ or generalized ischemia is Penn class Aa and considered low-risk. Nevertheless, surgical mortality can be considerable in this subgroup and may be related to modifiable factors. The objective of this study was to analyze 30-day mortality among ATAAD Penn class Aa patients with special reference to modifiable perioperative factors. Methods: Among all patients operated for ATAAD from 1990 to 2010, all Penn class Aa patients dying within 30 days were included in a retrospective descriptive study...

Inflammatory damage to the bowel, as occurs in inflammatory bowel disease (IBD), is debilitating to patients. In both patients and animal experimental models, histological analyses of biopsies and endoscopic examinations are used to evaluate the disease state. However, such measurements often have delays and are invasive, while endoscopy is not quantitatively objective. Therefore, a real-time quantitative method to assess compromised mucosal barrier function is advantageous. We investigated the correlation of in vivo changes in electrical transmural impedance with histological measures of inflammation...

Introduction: Diagnosis of hepatocellular carcinoma (HCC) is considerably delayed, being frequently done in the non-curative stage of disease. The reason for delayed diagnosis is indolent course in early stages and/or unspecific symptoms indistinguishable from underlying cirrhosis. Hitherto methods used for screening of HCC have important limitations. TRIMprob is a non-invasive method, which showed utility in detection of cancers located in prostate, breast, or urinary bladder. Aim: To determine the diagnostic accuracy of TRIMprob in detecting HCC in cirrhotic liver...

BACKGROUND Appendicitis is the most common cause of abdominal pain requiring emergent surgical intervention. Although typically presenting as right lower-quadrant pain, in rare cases it may present as left upper-quadrant pain secondary to abnormal position due to intestinal malrotation. Since atypical presentations may result in diagnostic and management delay, increasing morbidity and mortality, accurate and prompt diagnosis is important. Therefore, acute appendicitis should be considered in the differential diagnosis of left upper-quadrant abdominal pain...

UK guidelines for the sustainable control of parasites in sheep (SCOPS) were formulated with the primary aim of delaying development of anthelmintic resistance (AR) on UK sheep farms. Promoting their use requires the engagement and commitment of stakeholders. An important driver for behavioural change in sheep farmers is evidence of economic benefits. A recent evaluation of SCOPS guidance in practice demonstrated a significant reduction in anthelmintic use, suggesting economic benefits through a direct reduction in product and labour costs...

Pontocerebellar hypoplasia type 1 (PCH1) is a major cause of non-5q spinal muscular atrophy (SMA). We screened 128 SMN1-negative SMA patients from Bulgaria for a frequent mutation -p.G31A in EXOSC3, and performed a literature review of all genetically verified PCH1 cases. Homozygous p.G31A/EXOSC3 mutation was identified in 14 Roma patients, representing three fourths of all our SMN1-negative Roma SMA cases. The phenotype of the p.G31A/EXOSC3 homozygotes was compared to the clinical presentation of all reported to date genetically verified PCH1 cases...

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare autoinflammatory bone disorder of children and adolescents characterized by mono- or multi-focal inflammatory bone lesions that are culture-negative on biopsy, associated with periods of exacerbation and resolution that can last over several months to years. Although it is predominantly a disease of long bones and the spine, craniofacial involvement is not uncommon, affecting the mandible in up to a fifth of cases. Similarities with other etiologies of osteitis in clinical presentation and imaging, as well as the lack of specific symptoms or laboratory tests, make CRMO mainly a diagnosis of exclusion...
