Treatment of Congenital Afibrinogenemia in a Neonate With Critical Pulmonary Stenosis.

Fibrinogen deficiencies in neonates can lead to bleeding complications. In this report, we describe a case of congenital afibrinogenemia in a newborn with critical pulmonary stenosis who presented with bilateral cephalohematomas after an uncomplicated delivery. The initial use of cryoprecipitate was followed by administration of fibrinogen concentrate. We estimated a half-life of 24 to 48 hours with the concentrate product. This patient received fibrinogen replacement and had a subsequent successful cardiac repair. The drug's shorter half-life in this neonate contrasts with prior reports of longer half-life in older patients and is important to note in treating future neonatal patients with this diagnosis.

Mitigation strategies among cutaneous T-cell lymphoma patients with positive Staphylococcus aureus skin and soft tissue cultures have unclear impacts on the risk of subsequent bacteremia.

Infections originating in the skin/soft tissue are a major cause of mortality in cutaneous T-cell lymphoma (CTCL). We performed a retrospective analysis to characterize cutaneous cultures and assess risk factors for bacteremia among 69 patients with CTCL. Cutaneous infections and antimicrobial resistance were common. Black race and lymph node involvement were associated with bacteremia. Mitigating strategies for invasive infections in CTCL remain unclear. HighlightsSkin/soft tissue infections are common in cutaneous T-cell lymphoma (CTCL).Black race, lymph node involvement, and positive cultures for S. aureus, Gram-negative bacteria, or multiple organisms were associated with an increased rate of bacteremia.The role of antimicrobial prophylaxis and staphylococcus decolonization is unclear.

A modular microscopic smartphone attachment for imaging and quantification of multiple fluorescent probes using machine learning.

Portable smartphone-based fluorescent microscopes are becoming popular owing to their ability to provide major functionalities offered by regular benchtop microscopes at a fraction of the cost. However, smartphone-based microscopes are still limited to a single fluorophore, fixed magnification, the inability to work with a different smartphones, and limited usability to either glass slides or cover slips. To overcome these challenges, here we present a modular smartphone-based microscopic attachment. The modular design allows the user to easily swap between different sets of filters and lenses, thereby enabling utility of multiple fluorophores and magnification levels. Our microscopic smartphone attachment can also be used with different smartphones and was tested with Nokia Lumia 1020, Samsung Galaxy S9+, and an iPhone XS. Further, we showed imaging results of samples on glass slides, cover slips, and microfluidic devices. A 1951 USAF resolution test target was used to quantify the maximum resolution of the microscope which was found to be 3.9 µm. The performance of the smartphone-based microscope was compared with a benchtop microscope and we found an R2 value of 0.99 using polystyrene beads and blood cells isolated from human blood samples collected from Robert Wood Johnson Medical Hospital. Additionally, to count the particles (cells and beads) imaged from the smartphone-based fluorescent microscope, we developed artificial neural networks (ANNs) using multiple training algorithms, and evaluated their performances compared to the control (ImageJ). Finally, we did ANOVA and Tukey's post-hoc analysis and found a p-value of 0.97 which shows that no statistical significant difference exists between the performance of the trained ANN and control (ImageJ).

An Unusual Sticky Situation of New-Onset Right Sided Heart Failure.

This case highlights the importance of having constrictive pericarditis (CP) as a differential diagnosis in unexplained sign and symptoms of right-sided heart failure. This case portrays challenges in diagnosing CP caused by certain rheumatologic diseases despite advances in diagnostic modalities, clinical suspicion remains the most important tool for this diagnosis.

Community Perspectives on Zika Virus Disease Prevention in Guatemala: A Qualitative Study.

Zika virus, which is transmitted by Aedes aegypti mosquitoes and through sexual transmission, disproportionally affects the human fetus. Guatemala experienced a surge of Zika cases beginning in 2016. We conducted a qualitative study of community perceptions of the seriousness of Zika, as well as the effectiveness, feasibility, and collective efficacy of Zika prevention actions. Free listing elicited the preventive actions salient for 68 participants comprising pregnant women, men with a pregnant partner, and women likely to become pregnant; 12 focus group discussions in a highland and a lowland town explored other concepts through rank orderings of prevention practices depicted on cards. Participants' initial concern about Zika, based on recent experience with chikungunya and high media coverage, diminished because of its mild symptoms and reduced media coverage. Participants identified more than 32 salient preventive actions, many of which are considered effective by programs. Participants ranked water storage container cleaning and regular unspecified cleaning of the house and its surroundings as highly effective, feasible, and of high collective efficacy; however, the actions lacked the specificity needed to effectively destroy mosquito eggs. Community-level removal of tires and discarded containers had lower collective efficacy than household-level implementation because of the municipal and community cooperation needed. Condom use, although salient for Zika prevention, was hindered by gender roles. The findings indicate space for increasing self-efficacy for condom use among fathers-to-be, abandoning nonspecific terms such as "cleaning" and "standing water," increasing people's skills in using bleach as an ovicide, and promoting antenatal care and family planning counseling.

Evidence-Based Process for Prioritizing Positive Behaviors for Promotion: Zika Prevention in Latin America and the Caribbean and Applicability to Future Health Emergency Responses.

Since the 2015 Zika outbreak in Latin America and the Caribbean, a plethora of behavior change messages have been promoted to reduce Zika transmission. One year after the United States Agency for International Development (USAID) initiated its Zika response, more than 30 variants of preventive behaviors were being promoted. This situation challenged social and behavior change (SBC) programming efforts that require a coordinated response and agreed upon set of focus behaviors to be effective. To support USAID implementing partners in harmonizing prevention efforts to reduce Zika infection, we developed an evidence-based process to identify behaviors with the highest potential to reduce Zika infection and transmission. We compiled a full list of behaviors and selected the most promising for a full evidence review. The review included systematic keyword searches on Google Scholar, extraction of all relevant published articles on Aedes-borne diseases between 2012 and 2018, review of seminal papers, and review of gray literature. We examined articles to determine each behavior's potential effectiveness in preventing Zika transmission or reducing the Aedes aegypti population. We also developed assessment criteria to delineate the ease with which the target population could adopt each behavior, including: (1) required frequency; (2) feasibility of the behavior; and (3) accessibility and cost of the necessary materials in the setting. These behaviors were refined through a consensus-building process with USAID's Zika implementing partners, considering contextual factors. The resulting 7 evidence-based preventive behaviors have high potential to strengthen SBC programming's impact in USAID's Zika response: (1) apply mosquito repellent, (2) use condoms during pregnancy, (3) remove standing water, (4) cover water storage containers, (5) clean/remove mosquito eggs from water containers, (6) seek antenatal care, and (7) seek family planning counseling. This case study documents a flexible process that can be adapted to inform the prioritization of behaviors when there is limited evidence available, as during many emergency responses.

Herpetic whitlow of the toe presenting with severe viral cellulitis.

Herpetic whitlow of the toe is a common infection in an uncommon location, leading it to be frequently misdiagnosed; however, as the virus responds well to conservative management or antivirals alone, proper identification is necessary to prevent unnecessary interventions. We present a case of herpetic whitlow of the toe with an unusually ominous appearance in a previously healthy and otherwise well-appearing child. This case illustrates the spectrum of herpetic whitlow's clinical presentations and enourages consideration of the disease even for atypical location and severity.

Multidisciplinary Shared Decision Making in the Management of Ductal Carcinoma In Situ of the Breast.

BACKGROUND: Controversy continues regarding the use of adjuvant radiation therapy (RT) and hormonal therapy (HT) for patients undergoing breast-conserving therapy (BCT) for ductal carcinoma in situ (DCIS). METHODS: A prospective database was queried to identify women 18 years of age or older treated for DCIS from 2002 to 2013. RESULTS: BCT was completed for 300 patients with a median age of 66 years. The median DCIS size was 0.7 cm (range 0.1-6.0 cm). The DCIS grades were high (44 %), intermediate (37 %), and low (19 %). The closest margin was wider than 3 mm in 80 % and wider than 5 mm in 63 % of the cases. Adjuvant RT was administered to 183 patients (61 %), and the RT status of 9 patients (3 %) was unknown. RT was associated with age, DCIS size, comedo necrosis, grade, and treatment in 2002-2007 versus 2008-2013. Adjuvant HT was administered to 86 estrogen receptor-positive patients (39 %), and the HT status of 4 patients (2 %) was unknown. The median follow-up period was 63 months (range 4-151 months). The 5-year overall local recurrence (LR) rate was 4 % (95 % confidence interval [CI] 2.1-7.4 %). The 5-year LR rate was 3.9 % (95 % CI 1.8-8.6 %) for the RT patients and 4.1 % (95 % CI 1.6-10.7 %) for the patients not receiving RT. Of 13 LRs, 10 (77 %) were DCIS, and 3 (23 %) were invasive including one node-positive recurrence. CONCLUSIONS: Multidisciplinary and joint decision making in the treatment of DCIS results in a substantial and increasing number of patients forgoing adjuvant RT, adjuvant HT, or both. Reasonable 5-year LR rates suggest that such decision making can appropriately allocate patients to adjuvant therapies.
