Steroid-Induced Hiccups in a Patient Managed for Pseudo Foster-Kennedy Syndrome: A Case Report of Good Outcome With the use of Gabapentin

Efficacy of Switching From Oral to Intravenous Administration for Dexamethasone-Induced Hiccups in CyberKnife Radiotherapy: A Case Report

Steroids are commonly used for medical purposes. While hiccups are a recognized side effect of steroid therapy, we have not found any reports of hiccups interfering with the progress of radiotherapy. A case of dexamethasone (DEX)-induced hiccups (DIH) during CyberKnife radiotherapy (CKR) is presented. A 42-year-old man with neurofibromatosis type I had a history of malignant peripheral schwannomas originating in the right femur. We started to perform CKR with oral DEX at an increased dose of 4 mg/day for the recurrence of cranial metastasis and primary lesions. Severe hiccups developed four days after the increased DEX dose. DEX was stopped six days after CKR initiation, and the hiccups subsided over the next four days. However, the CKR procedure was not possible due to the patient's worsening swelling of the head and thigh lesions, which prevented the proper fit of the mesh face mask and body fixation device. Intravenous (IV) DEX 6.6 mg/day was initiated, which allowed the resumption of CKR due to reduced swelling of the lesions. The CKR was completed due to the absence of hiccups following the transition to IV DEX. DIH could occur even at a dosage of 4 mg/day when taken orally. Our case suggests the significance of recognizing DIH during radiotherapy. Switching the administration from oral to IV DEX may be an option for dealing with DIH.

Persistent hiccups after treatment of COVID-19 with dexamethasone: A case report

Hiccups are involuntary and spasmodic contractions of the diaphragm, and multiple etiological factors have been suggested to be involved. Medications, such as dexamethasone, as well as some diseases, such as pneumonia, can cause persistent (>48 h) hiccups. Here, we report a 58-years-old male who had a fever, myalgia, cough, and ground-glass view in the chest computed tomography, and his PCR test for Covid-19 was positive. During the treatment course, persistent hiccups were developed after taking dexamethasone and lasted for six days. All cardiac and neurologic examinations were performed, and all of them were normal. After evaluating all of the possible underlying causes, dexamethasone was replaced by prednisolone. Upon a change in his treatment regimen, hiccups began to stop, and his symptoms also disappeared. Hiccups may occur in patients who have pneumonia and other infectious diseases. Dexamethasone can also stimulate hiccups along with infections.
