ABSTRACT

La intoxicación por mordedura de serpiente es un problema de salud pública global. En la población pediátrica, la intoxicación por mordedura de serpiente presenta características diferentes que en los pacientes adultos. La Bungarus multicinctus es una especie de elápido sumamente venenoso. Las presentaciones clínicas documentadas después de la intoxicación por mordedura de Bungarus multicinctus son reacciones locales mínimas, insuficiencia respiratoria, dolor generalizado e hiponatremia potencialmente mortal. Presentamos el caso de una intoxicación por mordedura de Bungarus multicinctus en una niña con manifestaciones clínicas atípicas, incluidas necrosis tisular grave y trombocitopenia con coagulopatía.


Snakebite envenoming is a global public health problem. The pediatric population poisoned by snakebite envenoming has different features than adult patients. Bungarus multicinctus is a highly venomous species of the elapid snake. The documented clinical presentations following Bungarus multicinctus envenoming are minimal local reactions, respiratory failure, general pain, and life-threatening hyponatremia. We present an uncommon case of Bungarus multicinctus envenomation in a girl with unusual clinical findings, including severe tissue necrosis and thrombocytopenia with coagulopathy.

ABSTRACT

Objetivos. El objetivo de este estudio fue evaluar el riesgo clínico de la apendicitis con apendicolito y su importancia al elegir las estrategias terapéuticas.Métodos. Se analizó retrospectivamente a niños con diagnóstico de apendicitis aguda entre junio de 2011 y enero de 2017. Se dividió en un grupo con apendicolito(GA) y un grupo sin apendicolito (GSA) según la presencia o no de apendicolito durante la cirugía abierta. Se revisaron y compararon la presentación clínica, de laboratorios, los resultados de la tomografía computada y los cambios patológicos.Resultados. De 163 pacientes, se incluyó a 23 (media de edad: 6,1 años) en el GA y a 140 (media de edad: 8,1 años) en el GSA. Los pacientes en el GA tuvieron una hospitalización más extensa, mayor temperatura corporal, mayor frecuencia de diarrea, signo de Blumberg, aumento del porcentaje de neutrófilos, proteína C-reactiva y mayor riesgo de perforación. La puntuación en las escalas de Alvarado (8,3 ± 1,2 frente a 7,0 ± 1,3; P < 0,05) y de respuesta inflamatoria a apendicitis (10,7 ± 1,6 frente a 7,7 ± 1,9; P < 0,05) fue mayor en el GA que en el GSA; la presencia de fiebre y apendicolito se asoció con una mayor tasa de apendicitis perforada.Conclusiones. La apendicitis pediátrica con apendicolito representa un mayor riesgo clínico y tiende a causar apendicitis complicada


Objectives. This study aims to assess the clinical risk of pediatric appendicitis with appendicolith and its guiding significance in therapeutic strategies' selection.Methods. Children diagnosed with acute appendicitis from June 2011-January 2017 were analyzed retrospectively. Patient cohort was divided to appendicolith group (AG) and non- appendicolith group (NAG) based on whether the appendicolith presents or not in the open surgery. Clinical presentations, laboratory parameters, computed tomography findings, and pathological changes were reviewed and compared between two groups. Results. Among 163 patients, 23 (meanage,6.1yearsold)weredefinedin AG and 140; mean age, 8.1 years old) in NAG. The patients in AG demonstrated prolonged length of stay (12.4 ± 5.6d vs. 8.7 ± 5.0d, P <0.05), higher body temperature (38.2 ± 0.8 °C vs. 37.3 ± 0.8 °C, P <0.05), higher frequency of diarrhea (17 % vs. 3%, P <0.05), rebound tenderness (100 % vs. 87 %, P <0.05), increased neutrophil percentage (81.4 ± 8.0 % vs. 65.3 ± 22.8 %, P <0.05), C-reactive protein (33.13 ± 10.3 mg/L vs. 23.7 ± 13.7 mg/L, P <0.05), and great risk of perforation (78 % vs. 29 %, P <0.05). Alvarado score (8.3 ± 1.2 vs. 7.0 ± 1.3, P <0.05) and AIR score (10.7 ± 1.6 vs. 7.7 ± 1.9, P <0.05) of AG, were higher than NAG he presence of fever and appendicolith was associated with a high rate of perforated appendicitis.Conclusions. Pediatric appendicitis with appendicolith has greater clinical risk and tends to causing complicated appendicitis

ABSTRACT

Abstract Introduction The temporal behavior of atrial electrograms (AEGs) collected during persistent atrial fibrillation (persAF) directly affects ablative treatment outcomes. We investigated different durations of AEGs collected during persAF using recurrence quantification analysis (RQA). Methods 797 bipolar AEGs with different durations (from 0.5 s to 8 s) from 18 patients were investigated. Four RQA-based attributes were evaluated based on AEG durations: determinism (DET); recurrence rate (RR); laminarity (LAM); and diagonal lines' entropy (ENTR). The Spearman correlation (ρ) between each duration versus 8 s was calculated. AEG classification was performed following the CARTO criteria (Biosense Webster) and receiving operating characteristic (ROC) curves were created for the RQA variables. Results The RQA variables successfully discriminated the AEGs: the area under the ROC curves were as high as 0.70 for AEGs with 3.5 s or greater. Three types of AEGs were found using these variables: normal, fractionated and temporally unstable. The number of unstable AEGs decreased with longer AEG segments. Different AEG durations significantly affected the RQA variables (P<0.0001), with no statistical difference between the durations 6 s, 7 s and 8 s for DET, LAM and ENTR, and no difference between 7 s and 8 s for RR (P<0.0001). AEGs with 3 s or longer have shown ρ ≥ 80% for all variables. Conclusion The RQA variables have been shown effective in the characterization of AEGs collected during persAF with a shorter duration than current recommendations, which motivates their use for the characterization of atrial substrate during persAF ablation.

ABSTRACT

Pneumonia is primarily a disease that is usually managedmedically with antibiotics. However, in rare cases it mayprogress to necrotising pneumonia, which is an uncommonbut severe complication of bacterial pneumonia. This caseillustrates a typical case of necrotising pneumoniacomplicated with parenchymal and pleural complicationsuch as empyema, pneumothorax with possiblebronchopleural fistula. Early consultation with thoracicsurgeon can be life-saving.

ABSTRACT

This study was aimed to explore the correlation of mean platelet volume (MPV), fibrinogen (FIB) and blood rheology with the youth patients with cerebral infarction, so as to provide the basis for the clinical early diagnosis and treatment. The 109 patients with cerebral infarction aged between 18 - 45 were divided into three group: the large (> 10 cm(3)), middle (4 - 10 cm(3)) and small (< 4 cm(3)) area infarction; 30 healthy persons were served as control group. All the four groups were subjected to 16 examinations, such as MPV, FIB, and rheology (Lηb, Mηb, Hηb, ηp, Lηr, Mηr, Hηr, KVE, EAI, ERI, EDI, EEI, HCT, ESR). The results showed that all the MPV, FIB and rheology indexes of the different infarction groups were higher than those of healthy control group (P < 0.05). The MPV, FIB and rheology indexes in the large area infarction group were all higher than those in the small area infarction group (P < 0.05). The indexes of MPV, FIB and rheology in the various cerebral infarction area groups obviously decreased, but those did not reach to the level in the healthy control group (P < 0.05). The MPV, FIB content and rheology level correlated with infarction areas (r = 0.36, 0.29 and 0.48, respectively). It is concluded that the serious intensity of youth patients with cerebral infarction positively correlated with the levels of MPV, FIB and rheology indexes. Regular examination of above mentioned index may be useful to prevent youth patients from cerebral infraction.

ABSTRACT

Um interesse cada vez maior na reconstrução dupla banda do LCA tem estimulado um grande avanço nesta área de pesquisa e levado a um aumento no nosso conhecimento de anatomia, cinemática e função do joelho. Estudos recentes têm melhor definido o tamanho e orientação das inserções femorais e tibiais das bandas ântero-medial e póstero-lateral do LCA. O objetivo da reconstrução anatômica do LCA é utilizar esses novos conceitos para melhorar a técnica cirúrgica e mimetizar a anatomia original do LCA. Acreditamos que a reconstrução anatômica do LCA irá resultar em uma melhora na biomecânica e, consequentemente, uma melhora no quadro funcional de cada paciente.

ABSTRACT

<p><b>BACKGROUND</b>Men who have sex with men (MSM) have become one of the most risky populations for HIV infection in China. Though several cross-sectional sero-prevalence studies have been conducted, the annual HIV incidence remains unknown in this population.</p><p><b>METHODS</b>We applied IgG-capture BED-enzyme immunoassay (BED-CEIA) to define the recent HIV-1 infections among MSM in Beijing in the years 2005 and 2006 and the annual HIV incidence was estimated.</p><p><b>RESULTS</b>Overall, 1067 MSM samples were collected, including 526 samples in the year 2005 and 541 in 2006. In 2005, of 17 HIV seropositive samples, 7 were identified as recent HIV-1 infections and the estimated HIV infection incidence was 2.9% per year (95% CI, 0.8% - 5.0%). In 2006, of 26 HIV seropositive samples, 9 were identified as recent HIV-1 infections and the estimated annual incidence was 3.6% (95% CI, 1.3% - 5.9%), which was 0.7% higher than that in 2005. Individuals engaging in male group sexual intercourse (5.17% vs 0.87%, P = 0.019) and having receptive anal sexual intercourse more than five times (2.79% vs 0.33%, P = 0.047) in the past 6 months significantly increase the risk of being infected by HIV-1.</p><p><b>CONCLUSIONS</b>A high level of annual HIV-1 infection incidence was observed among MSM in Beijing for the consecutive years 2005 and 2006 with a continuous increasing trend. The rising incidence and related high risk behavior among MSM alarmed the health authorities and calls for more effective intervention strategies among this population.</p>

ABSTRACT

<p><b>BACKGROUND</b>Man who has sex with man (MSM) is one of the high risk groups for spreading HIV/AIDS. It was reported that the most prevalent human immunodeficiency virus type 1 (HIV-1) strain among MSM is subtype B; however, T cell immunity remains unknown across the HIV-1 B genome in this population.</p><p><b>METHODS</b>Using Elispot assay with synthetic peptides spanning the sequence of HIV-1 consensus B, HIV-1-specific cytotoxic T-cell lymphocyte responses were quantified among 3 treated and 19 untreated HIV-1 infected MSM from Beijing, China. Cross-sectional association between viral loads and cellular immune responses were analyzed.</p><p><b>RESULTS</b>Peptide pools corresponding to each HIV-1 protein were used for Env, Gag, Pol, Nef, Tat/Rev, Vpr/Vpu and Vif. The results showed that the magnitude of T cell responses in the 3 treated HIV(+) MSM group [median, 770 spot forming cells (SFCs) per 10(6) peripheral blood mononuclear cells (PBMCs)] might be significantly lower than that in the 19 untreated HIV(+) MSM group (median, 6175 SFCs per 10(6) PBMCs). Nef, Gag and Pol are the most frequently targeted HIV-1 antigens; and 16 subjects (73%) were identified with vigorous T cell immunity against each of these three proteins. The overall magnitude of T cell immunity closely related to its breadth (r = 0.72, P < 0.05) and was inversely but weakly associated with viral loads (r = -0.15). Further analysis showed that both Gag (r = -0.24) and Pol specific T cells (r = -0.12) contributed to this inverse association whereas Nef specific T cells showed no association with viral loads.</p><p><b>CONCLUSIONS</b>The magnitude of HIV-1 specific T cells is inversely but weakly associated with viral loads among MSM; HIV-specific T cell responses against conservative sequences (Gag and Pol) are the main contributors to this association among Chinese HIV(+) MSM. These findings have important implications for vaccine design.</p>
