Pseudotumor cerebri with status epilepticus in a child: A rare presentation of vitamin D deficiency.

Pseudotumor cerebri (PTC) encompasses a constellation of symptoms caused by elevated intracranial pressure of unclear etiology. Various associations have been described, rarely hypovitaminosis D. Vitamin D deficiency should be considered as a potential etiology of neurological manifestations like PTC and seizures in children. Early diagnosis and correction of vitamin D deficiency is key to preventing morbidity and achieving good outcomes.

Spontaneous splenic hematoma secondary to dengue infection: a rare case report.

Dengue infection may have various surgical complications. Splenic hematoma is a rare complication of dengue hemorrhagic fever and may be life-threatening. Case Presentation: A 54-year-old male, diagnosed with dengue infection detected at another hospital, presented on the 10th day of fever with left upper abdominal pain for 7 days without history of trauma. Urgent ultrasonography of the abdomen revealed findings suggestive of a splenic subcapsular hematoma, which was confirmed by computed tomography scan. The grade II splenic hematoma was being managed conservatively. Unfortunately, the patient developed hospital acquired pneumonia and died from septic shock. Clinical Discussion: Hemorrhagic manifestations are seen in the febrile and critical phase of dengue, but the spleen is infrequently involved. Splenic hematoma can lead to splenic rupture, which can be rapidly fatal. Specific treatment guidelines of such hematomas are needed in the context of dengue infection, as the treatment modality is controversial. Conclusion: Patients must be carefully evaluated for the complications and surgical manifestations of dengue as abdominal pain and hypotension from splenic hematoma may be misinterpreted as components of dengue hemorrhagic fever and dengue shock syndrome.

The QSPR-THESAURUS: the online platform of the CADASTER project.

The aim of the CADASTER project (CAse Studies on the Development and Application of in Silico Techniques for Environmental Hazard and Risk Assessment) was to exemplify REACH-related hazard assessments for four classes of chemical compound, namely, polybrominated diphenylethers, per and polyfluorinated compounds, (benzo)triazoles, and musks and fragrances. The QSPR-THESAURUS website (http: / /qspr-thesaurus.eu) was established as the project's online platform to upload, store, apply, and also create, models within the project. We overview the main features of the website, such as model upload, experimental design and hazard assessment to support risk assessment, and integration with other web tools, all of which are essential parts of the QSPR-THESAURUS.

Prioritisation of polybrominated diphenyl ethers (PBDEs) by using the QSPR-THESAURUS web tool.

The prioritisation of chemical compounds is important for the identification of those chemicals that represent the highest threat to the environment. As part of the CADASTER project (http: / /www.cadaster.eu), we developed an online web tool that allows the calculation of the environmental risk of chemical compounds from a web interface. The environmental fate of compounds in the aquatic compartment is assessed by using the SimpleBox model, while adverse effects on the aquatic compartment are assessed by the Species Sensitivity Distribution approach. The main purpose of this web tool is to exemplify the use of quantitative structure-activity relationships (QSARs) to support risk assessment. A case study of QSAR integrated risk assessment of 209 polybrominated diphenyl ethers (PBDEs) demonstrates the treatment and influence of uncertainty in the predicted physicochemical and toxicity parameters in probabilistic risk assessment.
