Novel mutations in NOTCH2 gene in infants with neonatal cholestasis.

Abstract: One cause of neonatal cholestasis (NC) is paucity of intrahepatic bile ducts which can be associated with Alagille syndrome or non- syndromic. Alagille syndrome is caused by autosomal dominant mutations in the Notch signaling pathway ligand Jagged1 in 94% of patients and mutations in the NOTCH2 receptor in <1% of patients. This is a retrospective case series studying infants with neonatal cholestasis found to have variants of unknown significance (VOUS) in NOTCH2. Sorting intolerant from tolerant (SIFT) and polymorphism phenotyping (PolyPhen) were utilized to predict a damaging effect. Five infants with NC without other features of Alagille syndrome were found to have one copy of a VOUS in NOTCH2, predicted to be damaging by SIFT and PolyPhen. Our cases support the notion that NOTCH2 mutations may result in hypoplastic biliary system. Further characterization of these variants is important to assist with our clinical approach to NC.

Uma visão evidente da prática baseada em evidências na medicina perinatal: ausência de evidência não é evidência de ausência

Abstract: OBJECTIVE: To provide valuable elements and some humor in this so-called era of "evidence-based practice" with the aim of helping clinicians make better choices in the care they deliver based on evidence, not simply or exclusively based on a randomized clinical trial (RCT) or meta-analysis (which may not be evidence). SOURCES: Books and peer-reviewed articles are quoted and listed in the bibliography. Evidence of life, learning from our own mistakes and many other evident facts that support this review are not quoted. SUMMARY OF THE FINDINGS: 1) "Absence of evidence is not evidence of absence" and "lack of evidence of effect does not mean evidence of no effect". 2) RCTs with "negative" results and those with "positive" results, but without outcomes that matter, often cannot conclude what they conclude. 3) Non-randomized clinical trials and practical trials may be important. 4) Research to prove is different than research to improve. 5) Clinical choice must assess effects on outcomes that matter to patients and their parents. 6) Quantifying adverse outcomes, number needed to damage and to treat is not that simple. CONCLUSIONS: Significant challenges inherent to health service research must be correlated to possible clinical applications using tools to have a more "evident view of evidence-based practice" in perinatal medicine, recalling that absence of evidence is not evidence of absence.

Impact of a Rapid Diagnostic Meningitis/Encephalitis Panel on Antimicrobial Use and Clinical Outcomes in Children.

Abstract: Rapid molecular diagnostic assays are increasingly used to guide effective antimicrobial therapy. Data on their effectiveness to decrease antimicrobial use in children have been limited and varied. We aimed to assess the impact of the implementation of the FilmArray Meningitis Encephalitis Panel (MEP) on antimicrobial use and outcomes in children. In an observational retrospective study performed at Atlantic Health System (NJ), we sought to evaluate the duration of intravenous antibiotic treatment (days of therapy (DoT)) for patients <21 years of age hospitalized and evaluated for presumptive meningitis or encephalitis before and after the introduction of the MEP. A secondary analysis was performed to determine if recovery of a respiratory pathogen influenced DoT. The median duration of antibiotic therapy prior to the implementation of the MEP was 5 DoT (interquartile range (IQR): 3–6) versus 3 DoT (IQR: 1–5) (p < 0.001) when MEP was performed. The impact was greatest on intravenous third-generation cephalosporin and ampicillin use. We found a reduction in the number of inpatient days associated with the MEP. In the regression analysis, a positive respiratory pathogen panel (RPP) was not a significant predictor of DoT (p = 0.08). Furthermore, we found no significant difference between DoT among patients with negative and positive RPP (p = 0.12). Our study supports the implementation of rapid diagnostics to decrease the utilization of antibiotic therapy among pediatric patients admitted with concerns related to meningitis or encephalitis.

Invasion is not an independent prognostic factor in high-grade glioma

Abstract: Purpose: The role of invasion as a prognostic factor in high-grade gliomas (HGG) remains controversial. An apparent increase in invasiveness following anti-angiogenic therapy makes this question clinically relevant. The goal of this study is to assess survival differences in patients with newly diagnosed HGG who present with diffuse invasive disease compared to those who did not, but went on to develop diffuse invasive disease following bevacizumab therapy. Materials and Methods: Twenty-three patients presented as newly diagnosed diffuse invasive HGG. All patients underwent surgical resection with radiation therapy and temozolomide for one year. Progression-free survival (PFS) and overall survival (OS) were compared to a control of 58 patients with focal high-grade glioma who received similar therapy, but that included bevacizumab at 10 mg/kg given every two weeks. Results: The patient characteristics were similar in each group. The median PFS and OS for invasive HGG patients were 6 and 13 months and for the focal HGG patients, 11 and 24 months, respectively (P=0.092 and P=0.071). In the subgroup of invasive HGG that showed significant angiogenesis, the median PFS and OS were 3 and 9 months, respectively. 56% of the focal HGG patients recurred as diffuse invasive relapse. For patients with focal HGG who recurred as invasive disease, the median PFS and OS were 9 and 21 months respectively. Conclusions: Presence of diffuse invasive disease not accompanied by angiogenesis either prior to therapy or subsequent to anti-angiogenic therapy does not seem to have prognostic significance. However, invasion accompanied by angiogenesis in newly diagnosed HGG may confer a poor prognosis.

Pelvic Tuberculosis Diagnosed during Operative Laparoscopy for Suspected Ovarian Cancer.

Abstract: Background. While the combination of a pelvic mass, very high serum level of CA-125, chest adenopathy, and ascites is concerning for advanced-stage ovarian cancer, the etiology of such a presentation can be due to disseminated pelvic tuberculosis. Case. A 67-year-old para 2 African-American woman presented with abdominal pain and shortness of breath. Subsequent CT and MR imaging demonstrated chest adenopathy, a pelvic mass, omental caking, and ascites. The patient underwent diagnostic laparoscopy with biopsy revealing noncaseating granulomas and subsequent tissue culture revealed Mycobacterium tuberculosis. The patient was diagnosed with disseminated pelvic tuberculosis and multidrug therapy was initiated. Conclusion. Pelvic tuberculosis can mimic advanced-stage ovarian cancer; thus obtaining a tissue sample may be beneficial to more appropriately direct treatment and planning for neoadjuvant therapies given the ineffectiveness of extensive surgical procedures in treating pelvic tuberculosis commonly employed in the treatment of advanced-stage ovarian cancer.
