Objective: To investigate the causes of 30-day unplanned revision surgery following one-stage posterior vertebral column resection (PVCR) for severe spinal deformity and the methods of prevention and management. Methods: A total of 112 severe deformity patients underwent one-stage PVCR for surgical treatment in the 306(th) Hospital of People's Liberation Army from May 2010 to December 2015 were retrospectively reviewed. Six patients required reoperation within 30 days after PVCR, including 2 males and 4 females with average age of 21 years (ranging from 12 to 38 years)...

We demonstrate a camera which can image methane gas at video rates, using only a single-pixel detector and structured illumination. The light source is an infrared laser diode operating at 1.651μm tuned to an absorption line of methane gas. The light is structured using an addressable micromirror array to pattern the laser output with a sequence of Hadamard masks. The resulting backscattered light is recorded using a single-pixel InGaAs detector which provides a measure of the correlation between the projected patterns and the gas distribution in the scene...

Tree masting is one of the most intensively studied ecological processes. It affects nutrient fluxes of trees, regeneration dynamics in forests, animal population densities, and ultimately influences ecosystem services. Despite a large volume of research focused on masting, its evolutionary ecology, spatial and temporal variability and environmental drivers are still matter of debate. Understanding the proximate and ultimate causes of masting at broad spatial and temporal scales will enable us to predict tree reproductive strategies and their response to changing environment...

Outbreaks of cutaneous leishmaniasis are relatively common among soldiers involved in nocturnal activities in tropical forests. We investigated the population dynamics of sand flies in a military training camp located in a remnant of Atlantic rainforest in northeastern Brazil, where outbreaks of cutaneous leishmaniasis have sporadically been described. From July 2012 to July 2014, light traps were monthly placed in 10 collection sites, being nine sites located near the forest edge and one near a horse stable...

OBJECTIVE: Cancer causes death to millions of people worldwide. Early detection of cancer in primary care may enhance patients' chances of survival. However, physicians often miss early cancers, which tend to present with undifferentiated symptoms. Within a theoretical framework of the hypothesis generation (HyGene) model, together with psychological literature, we studied how 2 factors-cancer prevalence and an alternative explanation for the patient's symptoms-impede early cancer detection, as well as prompt patient management...

Angiotropism is a marker of extravascular migration of melanoma cells along vascular and other structures and a prognostic factor in cutaneous melanoma. Because of this biological and prognostic importance in cutaneous melanoma, angiotropism was studied in uveal melanoma (UM). This retrospective study performed at a single ocular oncology referral center included 89 patients from the study period 2006-2008. All patients were diagnosed with UM from the choroid and/or ciliary body. All patients underwent enucleation for prognostic purposes and definitive therapy...

: Pediatric patients undergoing surgery for spinal deformity may benefit from central venous access to provide intraoperative monitoring and fluid resuscitation. For pediatric surgical patients requiring central access, we hypothesized that placing a peripherally inserted central catheter (PICC) line preoperatively should decrease time from induction of anesthesia to incision and result in improved patient safety and decreased operating room charges. This was a retrospective, nonrandomized, and case comparison study...

OBJECTIVES: Anatomical acetabular plates were recently introduced to fix acetabular fractures via the intra-pelvic approach. Therefore we asked: I.) Does the preshaped three dimensional suprapectineal plate interfere with or even impair the fracture reduction quality? II.) How often does the anterior intra-pelvic approach need to be extended by the first (lateral) window of the ilioinguinal approach? DESIGN: Observational case series SETTING:: Two Level one Trauma centresPatients / Participants: Patients with unstable acetabular fractures in 2014 INTERVENTION:: Fracture fixation with anatomical-preshaped, three-dimensional suprapectineal plates via the anterior intra-pelvic approach ± the first window of the ilioinguinal approach...

Introduction: Hospitalization of patients with cancer has a significant economic impact and avoidance where unnecessary has great potential for significant cost savings for patients, individual hospitals and the health system in general. Methods: Demographic, clinical and economical data were collected from medical records in our hospital retrospectively. Oncology clinicians reviewed medical records to categorize each hospitalization as “potentially avoidable” or “not avoidable.” Patient demographic and clinical data were abstracted and quantitative and qualitative analyses were performed to identify patient characteristics and outcomes associated with potentially avoidable hospitalizations...

BACKGROUND: South Africa's crude death rate was recorded as the highest in the world in 2014. In 2013, 47 murders occurred daily nationwide, and it was confirmed that sharp force fatalities were frequent events. The aim of our study was to review the fatalities of persons admitted to the Pretoria Medico-Legal Laboratory over a two-year period. Understanding the magnitude of the problem, identifying the most commonly injured area and the mechanism of death in cases where the patient died in hospital could aid in the clinical management of some of these cases in order to reduce mortality...

: Finding a Meckel's diverticulum during a laparotomy is rare, operating on a patient for a complication of diverticulum is rare, but if this complication is the result of a perforation of the diverticulum by a foreign body, then we are in the presence of a medical curiosity. OBJECTIVE: To present the following case because despite being known, the etiological agent that caused the perforation is very unusual. METHOD: male 53 years old with a history of emergency surgically underwent surgery for acute appendicitis 10 years where he underwent an appendectomy and a non-complicated Meckel's diverticulum was identified...

Neck trauma is a very important surgical emergency faced by ENT surgeons in day to day practice. They are potentially life threatening conditions due to the presence of many vital structures in this area. Timely presentation to the referral centre and proper multidisciplinary approach towards management plays a pivotal role in the healing pattern of the wound and prevention of serious complication like shock, sepsis, laryngeal stenosis or fistula formation. A retrospective study was done in ENT Department, NSCB Medical College, Jabalpur, Madhya Pradesh, India during the period of 2014-2016...

BACKGROUND: Sexual selection has been hypothesised as favouring mate choice resulting in production of viable offspring with genotypes providing high pathogen resistance. Specific pathogen recognition is mediated by genes of the major histocompatibility complex (MHC) encoding proteins fundamental for adaptive immune response in jawed vertebrates. MHC genes may also play a role in odour-based individual recognition and mate choice, aimed at avoiding inbreeding. MHC genes are known to be involved in mate choice in a number of species, with 'good genes' (absolute criteria) and 'complementary genes' (self-referential criteria) being used to explain MHC-based mating...

BACKGROUND/AIMS: Our physicians work to expand the possibilities to treat female patients with inflammatory bowel disease (IBD) who wish to become pregnant. Although many drugs, including 5-aminosalicylate (5-ASA), corticosteroids, immunomodulators, and biologics, are used safely during pregnancy, few reports have described the therapeutic regimen throughout pregnancy and the management of patients who relapse during pregnancy precisely. The aim of this study was to assess the management of patients with IBD during pregnancy...

Background/Aims: Spontaneous bacterial peritonitis (SBP) is one of critical complications in liver cirrhosis patients with ascites. We aimed to review clinical course of SBP patients in a 10-year period from single center. Methods: This study enrolled SBP patients between 2005 and 2015. Their medical records were reviewed. The laboratory findings of serum and ascites were examined, and characteristics of isolated microorganisms in ascites were analyzed. Results: Total 51 patients were enrolled...
