Urinary tract infections (UTIs) are common. The diagnosis is confirmed by urine culture which is costly and takes at least 24 hours before results are known. The aim of this study was to determine the diagnostic accuracy of dipstick test for the diagnosis of UTI in symptomatic adult patients. We conducted a cross-sectional study in the department of Infectious Diseases, Sousse-Tunisia during a two-year period. We included all patients with clinical signs of UTI. Urine samples were tested for the presence of leukocyte esterase (LE) and nitrites. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of LE and nitrites were calculated against urine culture as gold standard. Four hundred thirty one patients, 139 men (32%) and 292 women (68%) were included. One hundred sixty six patients (39%) had UTI. The most frequently isolated microorganism was Escherichia coli (75%). LE had a high sensitivity (87%) but a low specificity (64%), while nitrites had a high specificity (95%) but a low sensitivity (48%). Combined positive LE and nitrites had a high PPV (85%) and combined negative LE and nitrites had a high NPV (92%), while positive LE combined with negative nitrites had a low PPV (47%) and a low NPV (53%). In conclusion, in adult patients with UTI symptoms, an alternate diagnosis should be considered if the LE is negative, while an early empirical antibiotic therapy against Enterobacteriaceae should be started if the nitrites are positive.
Introduction: Cerebral malaria which occurs during the active infection is the most common neurological complication of malaria. Other complications including post-malaria neurological syndrome (PMNS) can rarely occur following complete recovery from the disease. We report a case of post-malaria neurological syndrome in a Tunisian patient.
Case presentation: A 26-year-old Tunisian man with no past medical history was admitted in 2016 for a muscle weakness of the 4 limbs, seizures, tetraparesis and myoclonus which appeared after he returned from Côte d’Ivoire where he had been treated three weeks ago for Plasmodium falciparum malaria with favorable outcome. Blood smears for malaria were negative. Brain MRI showed multiple hypersignal cerebral lesions. Investigations didn’t show any infectious, metabolic, toxic, vascular or tumoral etiology. Thus, the diagnosis of PMNS was considered. The patient was treated with methylprednisolone with favorable outcome. Two years later, he was completely asymptomatic.
Conclusion: PMNS should be considered in patients with neurological symptoms occurring within two months of cured acute disease in which blood smears for malaria are negative and other etiologies have been ruled out. In most cases, the disease is self-limited while in severe cases corticosteroid therapy should be prescribed with favorable outcome.

Invasive fungal rhinosinusitis is a rare infection that occurs primarily in immunocompromised patients. The fungal pathogen Alternaria alternata is rarely associated with rhinosinusitis. We report a case of A. alternata rhinosinusitis in an immunocompetent patient.
We report an observation of facial and upper limb demodicosis, revealing a human immunodeficiency virus infection. After an initial improvement with metronidazole, worsening of skin lesions related to immune reconstitution inflammatory syndrome was observed, requiring the use of steroids.
We report a case of a 21-year-old shepherd who presented with fever, left hypochondrium pain and splenomegaly. Blood tests showed thrombocytopenia and high liver enzymes. Computed tomography scan revealed the presence of hypodense lesions suggestive of splenic infarction. Echocardiography was without abnormalities. Laboratory evaluation for thrombophilia was negative. A bone marrow aspiration and a bone marrow biopsy were normal. Brucella serology was positive. The patient was treated with doxycycline, rifampicin and streptomycin for 12 weeks. Fever, abdominal pain and thrombocytopenia resolved promptly. At one year of follow-up, he remained well and no splenic infarction could be detected on ultrasonography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
