What Causes Spontaneous Pneumothorax?
Discussion “A pneumothorax is a collection of air in the pleural space, and it can be categorized into spontaneous, traumatic or iatrogenic. Spontaneous pneumothorax can be further classified into primary with no clinical evidence of underlying lung disease or secondary due to pre-existing lung disease.” Spontaneous pneumothorax is a condition that is relatively rare in pediatrics. There is a bimodal age distribution – neonates and late adolescence. It is caused by tearing of the visceral pleural. Clinical signs include chest pain, dyspnea, tachycardia, tracheal deviation towards contralateral side, hypot...

Development and function of group 2 innate lymphoid cells.
Abstract The innate lymphoid cell (ILC) family has recently expanded with the discovery of type-2 innate lymphoid cells (ILC2). These cells arise from lymphoid progenitors in the bone marrow and, under the control of the transcriptional regulators RORα and Gata3, they mature to give rise to IL-5, IL-9 and IL-13 producing ILC2. These cells are critical components of the innate immune response to parasitic worm infections and have also been implicated in the pathogenesis of asthma and allergy. Recent advances in our understanding of the molecular regulation of ILC2 development and function now present the opportuni...

Acute abdomen caused by eosinophilic enteritis: six observations.
Conclusions: Eosinophilic enteritis can originate acute abdomen processes where an urgent surgical treatment is necessary. The intraoperative aspect can be from a segment of small bowel with inflammatory signs up to a completely irrecoverable loop, where removing of the affected segment is the correct treatment, which can be done laparoscopically.

Myiasis (fly disease) and insectal disease generally are causing mental illness
Abstract: Mental illness by which psychosis is meant here is known to be caused mainly by imbalances of certain neurotransmitters in the brain. But, what is causing these imbalances? There has been a recent flurry of interest focusing on the possibility of parasitical disease. The appropriateness of this is based on the fact that organisms of the animal kingdom produce the same neurotransmitters. In fact stinging insects release them in their venoms.The proposal here is that insect larval parasites acting on the human brain and body may release such neurotransmitters and cause imbalances and altered mental states and is su...

New malaria vaccine could save millions of lives
Conclusion This is a promising step in the long struggle by scientists to develop a safe and effective vaccine against P. falciparum malaria. However, this was a tiny, early stage study and more research is required to replicate the results and to look further at the potential effectiveness of different doses. It is not certain how long such a vaccine may offer protection for and also, whether it would protect against other strains than the one tested here.  Travellers to malarial areas are strongly advised to avoid mosquito bites by using insect repellent and mosquito nets, and by covering up at all times. Medication ma...

Anisakis simplex: A new etiological agent of Kounis syndrome
Kounis syndrome (KS) is a rarely diagnosed condition which should always be kept in mind when an acute myocardial infarction (AMI) happens in the context of anaphylactic reactions, with or without clinical history of atopy or allergy . Anisakis simplex (AS), a common parasite of fish, is able to sensitize humans via the alimentary tract. An acute IgE-mediated generalized reaction (urticaria–angioedema–anaphylaxis) could be induced in a sensitized subject after consuming fish infested with the live larvae .

Anisakis - A food-borne parasite that triggers allergic host defences.
Abstract Anisakis is a parasitic nematode which infects fish and marine invertebrates, including crustaceans and molluscs. Ingestion of contaminated seafood can cause acute gastrointestinal diseases. Infection can be accompanied by severe allergic reactions such as urticaria, angioedema and anaphylaxis. Diagnosis of allergy due to Anisakis currently relies on the detection of serum IgE antibodies to allergenic proteins and a history of reactions upon exposure to fish. Anisakis proteins demonstrate considerable immunological cross-reactivity to proteins of related nematodes and other invertebrates such as crustacea...

NIH scientists develop new tests to detect drug-resistant malaria
Researchers have developed two tests that can discern within three days whether the malaria parasites in a given patient will be resistant or susceptible to artemisinin, the key drug used to treat malaria. The tests were developed by researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, working with French and Cambodian colleagues in Cambodia...

Tripped up by an unusual diagnosis?
Discussion West African trypanosomiasis ("African sleeping sickness") is caused by the protozoa Trypanosoma brucei gambiense. Neurological symptoms, characterised by increasing somnolence and cognitive disturbance, manifest during stage II of the disease when the parasite invades the central nervous system. Stage II disease is generally fatal if left untreated. We believe that this case demonstrates the longest reported latent period between trypanosome infection and clinical presentation with important implications for the understanding of trypanosome immunology. Trypansomiasis can cause hypergammaglobulinaemia which coul...

Neurocognitive sequelae following hippocampal and callosal lesions associated with cerebral malaria in an immune-naive adult
We report a case of a 36-year-old immune-naive Caucasian female who sustained a brain injury with neurocognitive sequelae, after a severe bout of falciparum malaria. On admission, she was unconscious, febrile, hypoglycaemic and passing black urine. She had returned from Ghana 2 days earlier. Her initial parasite count was 22%,...

Malaria vaccines: past, present and future
The currently available malaria control tools have allowed malaria elimination in many regions but there remain many regions where malaria control has made little progress. A safe and protective malaria vaccine would be a huge asset for malaria control. Despite the many challenges, efforts continue to design and evaluate malaria vaccine candidates. These candidates target different stages in the life cycle of Plasmodia. The most advanced vaccine candidates target the pre-erythrocytic stages in the life cycle of the parasite and include RTS,S/AS01, which has progressed through clinical development to the stage that it may b...
