Drug-induced fever is easy to overlook in respiratory departments. High fever is a rare side effect of trihexyphenidyl, which can be used clinically to treat Parkinson's disease. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a group of clinical syndromes caused by various diseases, resulting in water retention and refractory hyponatremia. However, pneumonia combined with malignant hyperthermia and SIADH has rarely been reported. We describe an unusual case of malignant hyperthermia and refractory hyponatremia due to trihexyphenidyl adverse reaction. ⋯ High fever and SIADH can be a rare adverse reaction to trihexyphenidyl. Therefore, possible drug factors should be considered in the case. Consideration of other possible causes can improve early diagnosis and treatment of patients with fever of unknown origins.

One of the Nigerian vision 2020 National Malaria strategic plans is control and subsequent eradication of malaria. The present report looks at outpatient malaria clinic visits for a 3-year period with a view of ascertaining whether control measures put in place over decades are being reflected in the decline of the disease. ⋯ The incidence of malaria in the region of this study is still high despite the effects made at reducing the scourge of the disease and would need timely intervention.

Systemic lupus erythematosus (SLE) is a chronic, rare autoimmune disease. In recent years, multiple monogenic diseases with early onset autoimmunity and lymphoproliferation have been identified, such as autoimmune lymphoproliferative syndrome, rat sarcoma (RAS)-associated autoimmune leukoproliferative disease, signal transducer and activator of transcription 3 gain-of-function syndrome and interleukin-2 receptor α deficiency. Therefore, we performed whole-exome sequencing in children with SLE with lymphoproliferation to identify genes associated with these conditions. ⋯ The SLE is a novel phenotype of somatic mutations in the NRAS gene and germline mutations in the PI3CKD gene. These genes, NRAS, TNFAIP3, and PIK3CD, should be considered candidates for children with SLE with lymphoproliferation. If patients with SLE and lymphoproliferation present with renal and hematologic involvement and recurrent fever, they need gene testing, especially male patients.

Case Reports
Refractory adult Coats disease treated with dexamethasone intravitreal implant: A case report.
Coats disease is a sporadic, retinal vascular abnormality, causing blindness. Several interventional methods, including laser photocoagulation, have been proposed; however, the use of intravitreal dexamethasone in refractory Coats disease is not well described. ⋯ Dexamethasone intravitreal implantation was effective in treating refractory Coats disease.

Comparative Study
Essential tremor vs idiopathic Parkinson disease: Utility of transcranial sonography.
Substantia nigra (SN) hyperechogenicity measured by transcranial sonography (TCS) is a promising biomarker for Parkinson disease (PD). The aim of this study was to explore the diagnostic accuracy of SN hyperechogenicity (SN) for differentiating PD from essential tremor (ET). A total of 119 patients with PD, 106 ET patients and 112 healthy controls that underwent TCS from November 2016 to February 2019 were included in this single-center retrospective case-control study. ⋯ In addition, measurement of the SN allowed to differentiate between patients with PD and healthy subjects with a sensitivity (91.6% and 90.8%) and specificity (88.4% and 89.3%) for readers 1 and 2, respectively. Interobserver agreement was excellent (к = 0.91). Measurement of SN on TCS images could be a useful tool to distinguishing patients with PD from those with ET.
