Background: Necrotizing fasciitis is a soft tissue infection that occurs predominantly in adults. Although rare, only 70 cases have been reported in neonates. This entity, most commonly caused by multiple organisms is often fatal, with 50% mortality. The combination of a low incidence and high mortality in this subgroup strengthens the need for early diagnosis, prompt recognition and immediate surgical treatment in order to improve survival. Aim: The aim of this case report is to bring awareness of a clinical condition that relies mostly on physical examination and where early diagnosis and immediate surgical treatment are needed in order to improve survival. Case presentation: We report the case of an 8-day-old boy presenting neonatal necrotizing fasciitis after circumcision. Patient presented with lower back erythema and areas of fluctuation. He was started on antibiotic therapy and 24 hours after admission, he was taken to the operating room for multiple fasciotomies, debridement and cleansing of affected areas. Findings were consistent with necrotizing fasciitis. After surgical intervention, local care was given until complete healing was achieved, approximately one month after admission. Conclusion: The surgeon must be attentive for the possible occurrence of this lethal infection that may develop post operatively after clean or clean-contaminated procedures. Preparation for treating these patients immediately with adequate fluid resuscitation, appropriate antibiotics and aggressive surgical debridement of non-viable tissue will provide the maximal potential for recovery. These prompt measures will offer the best chance for survival and eventually decrease the 50% mortality rate associated to the neonatal population.

圆齿轮的基圆与节圆同心并与啮合线相切。但非圆齿轮的基线却事先未知并不易确定。本文作为渐开线齿廓上特异点的几何轨迹来求得非圆齿轮的基线。由特异点—点该第二渐开线支线开始形成齿廓估算限制的许可齿高和要求的许可最小齿数。我们讨论了节线曲率半径对许可齿高的影响,并举例说明所推荐的方法。

Evaluation of Native Strains of Isaria fumosorosea （Wize） Against Anastrepha ludens （Loew）（Diptera： Tephritidae）

引用

Journal of Life Sciences 2012年第8期6卷 957-960页

We evaluated the pathogenicity of six strains 1. fumosorosea to determine their potential as biological control agents of A. ludens by performing bioassays under laboratory conditions （25 ± 2 ℃, 60± 5% R.H and 12：12 h L： D） exposing larvae and pupae to a concentration of 1 × 10^8 conidia per milliliter using three different methods： direct spraying, spray of soil and submerged for both instars. The results showed that direct spraying method Pfr-612 strain showed the highest mortality （47%） in pupae while for larvae was strain HIB-27 to 46%. Regarding spray of soil Pfr-612 strain showed the highest percentage of mortality for pupae and larvae with 45 and 57% mortality, respectively. Finally, for the submerged method in pupae HIB-27 strain showed 62% mortality whereas in larvae HIB-32 strain showed 46%. These results indicate that A. ludens is susceptible in at least two instars to L fumosorosea and make this fungus a promising agent for control of the Mexican fruit fly.
