The eyelid sign: a clue to bed bug bites.

In pediatric patients, determining the culprit insect in arthropod assaults can be challenging. The patient's history may be vague, the causative insect may not be readily associated with the bites, and the clinical appearance of bites can be variable. Six pediatric patients from the Penn State Milton S.

Bedbug complaints among public housing residents-New York City, 2010-2011.

Few studies have evaluated population-level risk factors for having a bedbug infestation. We describe characteristics associated with bedbug complaints among New York City Housing Authority (NYCHA) residents. Unique households receiving bedbug extermination services in response to a complaint during January 1, 2010 to December 31, 2011 were identified from NYCHA's central facilities work order database.

Repellency of selected chemicals against the bed bug (Hemiptera: Cimicidae).

In recent years, the common bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), became a major public health concern in urban communities. Bed bugs are notoriously difficult to control, and their bites are not tolerated by most people.

National estimates of noncanine bite and sting injuries treated in US Hospital Emergency Departments, 2001-2010.

Objective: Injuries resulting from contact with animals and insects are a significant public health concern. This study quantifies nonfatal bite and sting injuries by noncanine sources using data from the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP).

Methods: The NEISS-AIP is an ongoing nationally representative surveillance system used to monitor all types and causes of injuries treated in US hospital emergency departments (EDs).

Arthropod bites.

The phylum Arthropoda includes arachnids and insects. Although their bites typically cause only local reactions, some species are venomous or transmit disease. The two medically important spiders in the United States are widow spiders (Latrodectus), the bite of which causes intense muscle spasms, and the brown recluse (Loxosceles), which may cause skin necrosis.

Ivermectin causes Cimex lectularius (bedbug) morbidity and mortality.

Background: Bedbug infestations are increasing across North America and Europe, with more people presenting to Emergency Departments for treatment. Physicians cannot provide substantive treatment for people affected by bedbugs.

Study Objective: To determine if ivermectin, a relatively inexpensive and safe, long-acting oral anti-parasitic drug is able to cause bedbug morbidity and mortality.

Bed bugs reproductive life cycle in the clothes of a patient suffering from Alzheimer's disease results in iron deficiency anemia.

We report the case of an 82-year-old patient, hospitalized for malaise. Her clothes were infested by numerous insects and the entomological analysis identified them as being Cimex lectularius (bed bugs). The history of the patient highlighted severe cognitive impairment.

[Bedbugs: know them better. Deal with them better].

Bedbugs are hematophagic arthropods spread in the entire world and in all socio cultural environment. An augmentation of isolated or grouped cases (hotels, hostels, retirement homes) is observed in Geneva since 2012. Clinical manifestations can be various, however a psychological impact exists.

[Dermatitis and arthropods (Anobium punctatum and Cimex lectularius) in summer: three case reports].

We report three cases of pruritic dermatitis with erythematous maculopapules, having a similar clinical presentation, in summer, and caused by two different arthropods. In wandering diagnosis since sometimes several months, patients have made entomologic investigations in their home. Two of three samples, have shown an infestation by Anobium punctatum, the common furniture beetle, a xylophagous beetle (usually harmless for human).

Bed bug detection: current technologies and future directions.

Technologies to detect bed bugs have not kept pace with their global resurgence. Early detection is critical to prevent infestations from spreading. Detection based exclusively on bites is inadequate, because reactions to insect bites are non-specific and often misdiagnosed.

Human travel and traveling bedbugs.

Background: A dramatic increase of reported bedbug (Cimex lectularius and Cimex hemipterus) infestations has been observed worldwide over the past decade. Bedbug infestations have also been detected across a wide range of travel accommodations, regardless of their comfort and hygiene levels. Travelers are increasingly exposed to the risks of bedbug bites, infestation of personal belongings, and subsequent contamination of newly visited accommodations and their homes.

Bed bug saliva causes release of monocytic inflammatory mediators: plausible cause of cutaneous bite reactions.

Bed bugs may cause mild to severe cutaneous reactions. We studied the ability of bed bug salivary extract (SGE) to induce inflammatory reactions responsible for cutaneous manifestations and found that SGE stimulated the production of several potent chemokines and cytokines from macrophages. Chemokines induced by SGE included those known to recruit eosinophils (eotaxin), attract neutrophils [interleukin (IL)-8] or induce their survival and proliferation (granulocyte colony-stimulating factor).

Bedbugs: a primer for the health-system pharmacist.

Purpose: The history and life cycle of bedbugs, the identification and supportive treatment of bedbug bites, and the eradication and prevention of bedbug infestations are reviewed.

Summary: Cimex lectularius, known commonly as the bedbug, is a growing problem in the United States. While the bedbug population declined between the 1950s and the late 20th century, recent increases in international travel and immigration, the banning of dichlorodiphenyltrichloroethane, and insecticide resistance have caused a resurgence of bedbug infestations.

[Unclear pruritic and urticarial skin inflammation. Bed bug attack].

A 27-year-old woman presented with severe pruritus for a few weeks and diffuse urticarial erythema with pinhead-sized papules over the entire body. The skin lesions occurred directly after a stay in her secondary residence in London. The medical history, clinical picture and histological feature of an arthropod reaction in the skin biopsy, coupled with patient offering a bed bug specimen as evidence, secured the diagnosis of a cimicosis.

Infestation by pyrethroids resistant bed bugs in the suburb of Paris, France.

Bed bugs are hematophagous insects responsible for a re-emerging and challenging indoor pest in many countries. Bed bugs infestations may have health consequences including nuisance biting, cutaneous and systemic reactions. This resurgence can probably be attributed to factors such as increased international travel and development of resistance against insecticides.

Bedbug infestation.

The significant resurgence of bedbugs in the past decade has been attributed to pesticide resistance, more frequent travel, lack of public awareness, and inadequate pest control programs. Bedbugs are obligate blood parasites (insect family Cimicidae). They can withstand a large range of temperatures but are attracted to warmth and carbon dioxide.

Bed bugs in healthcare settings.

Infestations caused by bed bugs have resurfaced during the past decade across all continents. Even though bed bugs primarily cause skin manifestations in humans, a major stigma is placed upon people or institutions found to carry them. It is important for healthcare facilities to be prepared for this pest by implementing policies, carefully selecting materials used for hospital furniture, and educating providers on early identification and control.
