Key Clinical Message: Negative myoclonus may present in the early stages of cefepime neurotoxicity. Cefepime neurotoxicity typically presents as reduced consciousness, myoclonus, and seizures; however, negative myoclonus is uncommon. This video shows an older woman with cefepime neurotoxicity that presented as a negative myoclonus of the upper limbs. [ABSTRACT FROM AUTHOR]

Elevation of ALP is an abnormal feature in TAFRO syndrome, but the cause is unknown. This article is the first report that histologically showed intrahepatic cholangitis may be the cause of ALP elevation in TAFRO syndrome. [ABSTRACT FROM AUTHOR]

Penicillium marneffei (Talaromyces marneffei) infection sometimes occurs in HIV‐infected patients in South‐East Asia. However, reports on asymptomatic cases are rare. Herein, we report a case of a 27‐year‐old Burmese HIV‐positive woman with pulmonary penicilliosis. Chest radiography showed a lung mass; however, the patient did not have any respiratory symptoms. Cultures of bronchoalveolar lavage and lung tissue grew P marneffei. The patient was diagnosed with penicilliosis and successfully treated with amphotericin B and itraconazole. Our findings suggest that P marneffei infection should be considered in the differential diagnosis of a lung mass in HIV‐infected patients, even when asymptomatic for respiratory symptoms.

Wernicke encephalopathy is caused by vitamin B1 deficiency. It presents as a triad consisting of altered mental status, oculomotor dysfunction, and gait ataxia. Early vitamin B1 administration alleviates symptoms. We present a video of gaze‐evoked nystagmus in an elderly patient with Wernicke encephalopathy. It is often difficult to evaluate the mental and ambulatory states of frail elderly patients with dementia. In such cases, nystagmus is the only useful physical finding in the diagnosis of Wernicke encephalopathy. [ABSTRACT FROM AUTHOR]

Rapidly destructive coxarthrosis is a rare entity of unknown etiology that is characterized by rapid hip joint destruction. Blood tests are thought to be non‐specific. However, we herein show a patient with rapidly destructive coxarthrosis, which was accompanied by fluctuating C‐reactive protein level. [ABSTRACT FROM AUTHOR]

Antihistamines are known risk factors for restless legs syndrome (RLS). However, reports on RLS associated with fexofenadine or its combinations are rare. Here, we report a 30‐year‐old woman with RLS that was induced by fexofenadine/pseudoephedrine. She had been taking fexofenadine/pseudoephedrine for three months and felt a strong urge to move her legs at night, which was relieved by movement. Her condition improved by taking pramipexole, which she discontinued subsequently because of dizziness. One month later, she quitted taking fexofenadine/pseudoephedrine, after which her symptoms disappeared a week later. This case study demonstrates that RLS can be induced by fexofenadine/pseudoephedrine and we should always consider the possibility of drug‐induced RLS. [ABSTRACT FROM AUTHOR]
