Mycobacterium mageritense infection following mastectomy and breast reconstruction requiring triple antibiotic therapy and surgical debridement.

A 40-year-old woman was referred to infectious disease specialists for a Mycobacterium mageritense skin infection following mastectomy and bilateral reconstruction with deep inferior epigastric perforator flap. Her case demonstrates the difficulty in treating non-tuberculosis mycobacterial infections, especially the rarely seen species. She failed to respond to dual antibiotic therapy containing imipenem-cilastin despite reported sensitivity. Additionally, her course was complicated by intolerance to various regimens, including gastrointestinal distress, a drug rash with eosinophilia and systemic symptoms, and tendinopathy. With few published data, no treatment guidelines, and limited medications from which to choose for M. mageritense, her treatment posed a challenge. She ultimately required aggressive surgical intervention and a triple therapy antibiotic regimen. The duration of our patient's treatment and the extent of her complications suggest a potential need for early surgical intervention in postsurgical wounds infected with M. mageritense that do not respond to conventional treatment.

Treatment for Severe Coronavirus Disease 2019 With the Seraph-100 Microbind Affinity Blood Filter.

To determine whether Seraph-100 (Exthera Medical Corporation, Martinez, CA) treatment provides clinical benefit for severe coronavirus disease 2019 cases that require mechanical ventilation and vasopressor support. DATA SOURCES: The first two patients in the United States treated with the novel Seraph-100 device. These cases were reviewed by the Food and Drug Administration prior to granting an emergency use authorization for treatment of coronavirus disease 2019. STUDY SELECTION: Case series. DATA EXTRACTION: Vasopressor dose, mean arterial pressure, temperature, interleukin-6, C-reactive protein, and other biomarker levels were documented both before and after Seraph-100 treatments. DATA SYNTHESIS: Vasopressor dose, temperature, interleukin-6, and C-reactive protein levels declined after Seraph-100 treatments. Severe acute respiratory syndrome coronavirus 2 viremia was confirmed in the one patient tested and cleared by the completion of treatments. CONCLUSIONS: Seraph-100 use may improve hemodynamic stability in coronavirus disease 2019 cases requiring mechanical ventilation and vasopressor support. These findings warrant future study of a larger cohort with the addition of mortality and total hospital day outcomes.

Providing care to military personnel and their families: how we can all contribute.

Providing medical care to members of the military and their families remains a societal duty carried out not only by military physicians but also, and in large part, by civilian providers. As many military families are geographically dispersed, it is probable that all physicians at some point in their training or careers will care for this unique patient population. Understanding the military culture can help physicians provide the best care possible to our military families, and inclusion of military cultural competency curricula in all medical schools is a first step in advancing this understanding. The authors review the knowledge, skills, and attitudes that all health professionals should acquire to be able to care for those who serve and offer recommendations for developing these among all students and trainees.

Airway management of tetanus after the Haitian earthquake: new aspects of old observations.

Two men developed severe tetanus after the 2010 Haitian earthquake. They were admitted to the United States Naval Ship Comfort, a hospital ship sent to provide humanitarian relief. Severe masseter and intercostal muscle spasm impaired airway access and ventilation. Propofol and sevoflurane relieved the tetany, allowing airway control and ventilation without intubation or neuromuscular blocking drugs during wound debridement. Presynaptic impairment of inhibitory neurotransmitter release by tetanospasmin toxin is countered by enhancement of spinal cord postsynaptic inhibitory receptor activity by general anesthetics. Avoidance of tracheal intubation and mechanical ventilation during anesthesia may be desirable in the settings of limited resources in which tetanus usually presents.

The 2010 Haiti earthquake: a pathology perspective aboard the USNS Comfort.

The US Navy hospital ship USNS Comfort played an integral role in the initial phases of Operation Unified Response-Haiti following the devastating earthquake that struck near Port-Au-Prince, Haiti, on January 12, 2010. Deployed to Haiti from its home in Baltimore, Maryland, just 4 days after the earthquake, the USNS Comfort would become the region's primary tertiary casualty receiving center for 6 weeks. The pathology and laboratory department staff onboard the ship helped support the mission and experienced unique mass casualty/disaster relief scenarios while underway. This article reviews the accounts of the core laboratory, microbiology, anatomic pathology, and blood bank divisions on the USNS Comfort from the chaotic first few weeks to the final patient discharge 40 days after Operation Unified Response-Haiti began.

Difficulties in the diagnosis and management of a US servicemember presenting with possible chronic Q fever.

A 34 year old corpsman developed acute Q fever upon return from Iraq. Subsequent testing demonstrated trace mitral regurgitation and widely discrepant serologic testing results between commercial and reference laboratories. We discuss the dilemma of isolated minor echocardiographic abnormalities and propose caution in the interpretation of Q fever serologic tests.

Vaccination in patients with HIV infection.

Although vaccine-preventable diseases are common in HIV, concerns about vaccine safety and lack of efficacy in this patient population often lead to missed opportunities for vaccination. In this article, we review the literature regarding vaccine risks and benefits and offer recommendations regarding their use and timing in patients with HIV infection.
