Background: Effective anticoagulation routinely precludes patients from receiving intravenous thrombolysis with recombinant tissue plasminogen activator to reverse severe symptoms of ischemic stroke. We report what we believe to be the first case of ischemic stroke successfully treated with recombinant tissue plasminogen activator after antagonizing dabigatran with the monoclonal antibody idarucizumab, recently approved worldwide.
Case Presentation: A 75-year-old Caucasian man presented to our hospital with severe aphasia and mild hemiparesis.
Unlabelled: The evolution and persistence of ocular pathology was assessed in a cohort of Onchocerca volvulus infected patients treated annually with ivermectin for 23 years. Patients were resident in rural Central and Kara Region of Togo and ocular examinations included testing of visual acuity, slit lamp examination of the anterior eye segment and the eye fundus by ophthalmoscopy. Before ivermectin treatment, vivid O.

To investigate the effect of residual adult filaria on the immune response profile, chemokines and cytokines were quantified 1) in onchocerciasis patients who developed an occult O.

The Institute for Tropical Medicine at University of Tübingen has established 30 years ago in Togo a Research Centre and Onchocerciasis Reference Laboratory (ORL). Onchocerca volvulus infection control and of other neglected tropical diseases has been the focus of activities, and those were performed together with the National Institute of Hygiene in Togo, the Medical Faculty at University of Lomé, national disease control programs and district and regional hospitals. The ORL contributed significantly to the assessment of ivermectin as the prime choice for onchocerciasis treatment, and 24 years of repeated annual treatment with ivermectin has progressively reduced disease prevalence and notably the level of ocular and dermal manifestations of onchocerciasis in the endemic population.

O. volvulus-specific antibody reactivity and cellular cytokine production were investigated in onchocerciasis patients receiving ivermectin (150 microg/kg) annually for 16 years.

Ivermectin treatment will effectively diminish microfilariae (Mf) of Onchocerca volvulus in the skin of patients, but therapy is associated with adverse host inflammatory responses. To investigate the association of proinflammatory chemokines with the intensity of infection and clinical adverse reactions, chemokine serum levels were measured in patients following ivermectin treatment (100 microg/kg, 150 microg/kg or 200 microg/kg) or placebo. The density of O.

Evidence is mounting that point mutations on the Pfcrt and possibly the Pfmdr1 genes are conferring plasmodial resistance to chloroquine. In 1998, atypically strong rainfalls led to an increased activity of falciparum malaria in Mauritania that affected non-endemic regions bordering the Saharan desert.

This is one of the first studies for the Sahel, where atypically strong rainfalls in 1998 and 1999 led to a severe outbreak of falciparum malaria in south-east Mauritania. During a study on in vivo-drug resistance against chloroquine we collected blood samples of patients with fever in two medical centres located in non-endemic and hypoendemic areas.

In this study, the prevalence of these mutations was examined in samples from south-east Mauritania, where atypically strong rainfalls in 1998 and 1999 led to a severe outbreak of falciparum malaria. We analysed 386 samples by polymerase chain reaction (PCR) for infection with P.

The densities of Onchocerca volvulus microfilariae (mf) in treated patients remained significantly reduced, whereas the number of permanently amicrofilaridermic patients (subclinical infection) increased with repeated treatments. In vitro cellular responses to O.

As expected, Onchocerca volvulus microfilariae in the skin were greatly reduced in number soon after drug treatment, but microfilariae of Mansonella perstans reacted differently. Microfilarial densities of M.

Untreated patients tested for delayed cutaneous hypersensitivity (DCH) to seven recall antigens showed lower responses than infection-free control individuals (P less than 0.01), but 6 and 14 months after treatment DCH reactions increased to similar levels to those seen in the controls.

The people who were affected with the disease and were to be treated have accepted the treatment. The secondary reactions that the patients had experienced had the highest effects on the second and third day after receiving treatment.
