Regression of metastatic malignant melanoma with dupilumab: A case report.

Excoriated pruritus can be an intolerable symptom in patients with cancer where Type 2 inflammation and its associated cytokines IL-4 and IL-13 play major roles in the pruritus. Dupilumab, an antibody blocking IL-4 and IL-13, is approved for treating moderate to severe atopic dermatitis (AD) where itching is a significant symptom. We present a case report of intractable malignancy-associated AD and pruritus with eosinophilia in a patient with stage IV malignant melanoma who was treated with dupilumab.

Comparative analysis of sleeve conversions of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2020 Database.

Background: Although the sleeve gastrectomy (SG) is the dominant bariatric procedure, studies have shown conversion rates of up to 30%. These conversions are generally for weight regain (WR), insufficient weight loss (IWL) or gastroesophageal reflux disease (GERD). Before 2020, details on why conversions were being performed were not collected in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Participant Use Data File (PUF).

Does the use of bioabsorbable mesh for hiatal hernia repair at the time of bariatric surgery reduce recurrence rates? A meta-analysis.

Background: Anywhere from 16% to 37% of patients undergoing bariatric and metabolic surgery are estimated to have a hiatal hernia. To address the lack of long-term data showing the efficacy of bioabsorbable mesh in reducing the recurrence of hiatal hernia in patients who undergo bariatric surgery, we evaluated the world literature and performed a meta-analysis.

Objective: To evaluate hiatal hernia recurrence rates after placement of bioabsorbable mesh in bariatric patients.

Does bioabsorbable mesh reduce hiatal hernia recurrence rates? A meta-analysis.

Introduction: The use of bioabsorbable mesh at the hiatus is controversial. Long-term data are scant. We evaluated the world literature and performed a meta-analysis to determine if these meshes were effective in reducing recurrence.

The Yellow Fever Vaccine Misadventure of 1942.

In 1942, a hepatitis B outbreak occurred in the US Army after vaccination with contaminated lots of 17D yellow fever vaccine; long-term sequelae were surprisingly limited, and retrospective studies of carrier rates, cirrhosis, and hepatocellular carcinoma were found to be minimal. Later studies identified the contaminant as hepatitis B virus (HBV) in the human serum component of the vaccine. Other than 2 follow-up studies of long-term sequelae and reports within US Military archives, the event has never been fully elucidated in its proper historical context in the medical literature available through MEDLINE (PubMed).

A Century in the Life of the Control of Communicable Diseases Manual: 1917 to 2017.

The Control of Communicable Diseases Manual, a premier publication of the American Public Health Association, celebrates its centennial in 2017. The Control of Communicable Diseases Manual has evolved in format and content through 20 separate editions. This article is a follow-up to an earlier article, titled "Evolution of the Control of Communicable Disease Manual: 1917 to 2000," that appeared in the Journal of Public Health Management & Practice in 2001.

Yellow fever, Asia and the East African slave trade.

Yellow fever is endemic in parts of sub-Saharan Africa and South America, yet its principal vectors--species of mosquito of the genus Aedes--are found throughout tropical and subtropical latitudes. Phylogenetic analyses indicate that yellow fever originated in Africa and that its spread to the New World coincided with the slave trade, but why yellow fever has never appeared in Asia remains a mystery. None of several previously proposed explanations for its absence there is considered satisfactory.

Antibody-mediated rejection as a contributor to previously unexplained early liver allograft loss.

We analyzed 60 patients with idiopathic early allograft loss (defined as death or retransplantation at <90 days) to determine the relative contribution of preformed donor-specific human leukocyte antigen alloantibodies (DSAs) to this endpoint, and we defined strict criteria for the diagnosis of antibody-mediated rejection (AMR) in liver allografts. The inclusion criteria encompassed the availability of a pretransplant serum sample and both postreperfusion and follow-up tissue specimens for a blinded, retrospective re-review of histology and complement component 4d (C4d) staining. AMR was diagnosed on the basis of the presence of all 4 of the following strict criteria: (1) DSAs in serum, (2) histopathological evidence of diffuse microvascular injury/microvasculitis consistent with antibody-mediated injury, (3) diffuse C4d staining in the portal microvasculature with or without staining in the sinusoids or central veins in at least 1 sample, and (4) the exclusion of other causes of a similar type of injury.

The 1802 Saint-Domingue yellow fever epidemic and the Louisiana Purchase.

Epidemics have been pivotal in the history of the world as exemplified by a yellow fever epidemic in the Caribbean that clearly altered New World geopolitics. By the end of the 18th century, yellow fever--then an "emerging disease"--was widespread throughout the Caribbean and particularly lethal in Saint-Domingue (present day Haiti). From 1793 to 1798, case fatality rates among British troops in the West Indies (including Saint-Domingue) were as high as 70%.

New hypothesis for cause of epidemic among native Americans, New England, 1616-1619.

In the years before English settlers established the Plymouth colony (1616-1619), most Native Americans living on the southeastern coast of present-day Massachusetts died from a mysterious disease. Classic explanations have included yellow fever, smallpox, and plague. Chickenpox and trichinosis are among more recent proposals.

Influence of flow-through and renewal exposures on the toxicity of copper to rainbow trout.

We examined changes in water chemistry and copper (Cu) toxicity in three paired renewal and flow-through acute bioassays with rainbow trout (Oncorhynchus mykiss). Test exposure methodology influenced both exposure water chemistry and measured Cu toxicity. Ammonia and organic carbon concentrations were higher and the fraction of dissolved Cu lower in renewal tests than in paired flow-through tests.

Alexander the Great and West Nile virus encephalitis.

Alexander the Great died in Babylon in 323 BC. His death at age 32 followed a 2-week febrile illness. Speculated causes of death have included poisoning; assassination, and a number of infectious diseases.

'Real-life burden of depression' surveys--GP and patient perspectives on treatment and management of recurrent depression.

Depression is a chronic, recurrent illness carrying a heavy burden for the health service and the community. Current evidence suggests that the majority of patients with depression will experience recurrent episodes of illness, although there is extensive evidence that continuation therapy with antidepressant drugs will prevent relapse. Two surveys were designed and distributed in the UK in 2002 to compare the expectations of patients and GPs in the management of relapse in depression.
