A nosocomial Pseudomonas aeruginosa ST3495 isolated from a wild Burmese python (Python bivittatus) with suppurative pneumonia and bacteremia in Hainan, China.

Pseudomonas aeruginosa is a common infectious agent associated with respiratory diseases in boas and pythons, however, the histopathology, resistance and virulence are yet described for this species. In this study, we investigated a dying Burmese python rescued from tropical rainforest in Hainan. Clinical signs were open-mouthed breathing, abnormal shedding and anorexia. Abundant yellow mucopurulent secretions were observed in highly ectatic segmental bronchi by postmortem. Histopathological lesions included systemic pneumonia, enteritis, nephritis and carditis. P. aeruginosa was the only species isolated from heart blood, kidney, trachea and lung. The phenotype analysis demonstrated that the isolates had strong biofilm, and were sensitive to amikacin, spectinomycin, ciprofloxacin, norfloxacin and polymyxin B, moreover, the LD50 of the most virulent isolate was 2.22×105 cfu/mL in a zebrafish model. Molecular epidemiological analysis revealed that the isolates belonged to sequence type 3495, the common gene patterns were toxA + exoSYT + phzIM + plcHN in virulence and catB + blaTEM + ant (3'')-I+ tetA in resistance. This study highlights that P. aeruginosa should be worth more attention in wildlife conservation and raise the public awareness for the cross infection and cross spread between animals and human.

Morphological changes of frankel functional regulator III in mixed dentition with class III malocclusion / Cambios morfológicos del regulador funcional frankel III en dentición mixta con maloclusión clase III

The aim of this study was to evaluate the hard and soft tissue profile changes following treatment of functional and mild skeletal class III malocclusion in mixed dentition by means of the Frankel functional regulator (FR-3) appliance, and to reveal the mechanism and effectiveness of treatment with FR-3 appliance. Twenty-six patients (chronological mean age, 8.7±1.4 years; mean treatment duration, 10.3±1.3 months) with functional and mild skeletal class III malocclusion were selected and treated with FR-3 appliances. Lateral cephalogram was taken pre- and post-treatment, and the data was analyzed by paired-samples t test with SPSS22.0 software package. Differences were considered statistically significant at P < 0.05. The results demonstrated that the FR-3 appliance produced a statistically significant decrease in L1-NB, L1-MP, U1-L1 (P<0.01) and an increase greatly in ANB, MP-FH, Y axis, ANSMe, ANS-Me/N-Me and overjet (P<0.01). SNA, SNB were increased significantly (P<0.05). Meanwhile, N'-Sn-Pog', ULSn-SN, LLSiSN increased, S-N'-Si, LL-EP decreased with significant difference (P<0.01). S-N'-Sn, Cm-Sn-UL, UL-EP, Sn-Mes and Ns-Mes increased with significant difference (P<0.05). Therefore it was concluded that after FR-3 treatment, the position of mandible may rotate clockwise backwards and downwards, with the labioversion of upper incisors and linguoversion of lower incisors. Although point A moved mesially, the length and position of the maxilla did not change significantly. With the protrusion of upper lip and the retrusion of lower lip, the relationship among nose, upper lip, lower lip and chin become harmonious, the profile of soft tissue is more coordinated and attractive.

El objetivo de este estudio fue evaluar los cambios en el perfil de los tejidos duros y blandos después del tratamiento de la maloclusión funcional y leve de la clase III esquelética en la dentición mixta mediante el aparato regulador funcional Frankel (FR-3), y revelar el mecanismo y efectividad del tratamiento con el aparato FR-3. Veintiseis pacientes (edad media 8,7 ± 1,4 años; duración media del tratamiento, 10,3 ± 1,3 meses) con maloclusión funcional y leve de clase esquelética III fueron seleccionados y tratados con aparatos FR-3. El cefalograma lateral se tomó antes y después del tratamiento, y los datos se analizaron mediante la prueba t de muestras con el software SPSS22.0. Las diferencias se consideraron estadísticamente significativas a P <0,05. Los resultados demostraron que el dispositivo FR-3 produjo una disminución estadísticamente significativa en L1-NB, L1MP, U1-L1 (P <0,01) y un gran aumento en ANB, MP-FH, eje Y, ANS-Me, ANS -Me / N-Me y overjet (P <0,01). SNA, SNB se incrementaron significativamente (P <0,05). Mientras tanto, N'Sn-Pog', ULSn-SN, LLSi-SN aumentaron, S-N'-Si, LL-EP disminuyeron con una diferencia significativa (P <0,01). S-N'-Sn, Cm-Sn-UL, UL-EP, Sn-Mes y Ns-Mes aumentaron con una diferencia significativa (P <0,05). Por lo tanto, se concluyó que después del tratamiento con FR-3, la posición de la mandíbula puede girar en sentido reloj hacia atrás y hacia abajo, con labioversión de los incisivos superiores y linguoversión de los incisivos inferiores. Aunque el punto A se movió mesialmente, la longitud y la posición del maxilar no cambiaron significativamente. Con la protuberancia del labio superior y la retrusión del labio inferior, la relación entre la nariz, el labio superior, el labio inferior y el mentón se armoniza, el perfil del tejido blando es más coordinado y atractivo.

Comparison of the effect of mesh-plug, Lichtenstein, transabdominal preperitoneal, and totally extraperitoneal hernia repair: A network meta-analysis.

OBJECTIVE To compare Mesh-plug, Lichtenstein, transabdominal preperitoneal (TAPP), and totally extraperitoneal (TEP) repairs in regards to operation time, seroma, infection, and recurrence of inguinal hernia repair. METHODS Relevant literature was searched in the Cochrane Library, Pubmed, and Embase. Furthermore, the analysis of randomized controlled studies (RCTs) was performed using methods recommended by the Cochrane Collaboration. The main outcomes including operation time, seroma, infection, and recurrence were evaluated. RESULTS A total of 38 RCTs with 3255 patients were included in the meta-analysis. In addition, the comparison between Mesh-plug, Lichtenstein, TAPP, and TEP showed the differences were not significant regarding operation time, seroma, infection, and recurrence. CONCLUSIONS Meta-analysis suggests that Mesh-plug, Lichtenstein, TAPP, and TEP are comparable in the outcomes of hernia repair, such as operation time, seroma, infection, and recurrence.
