COVID-19 Rekindling Herpes Zoster in an Immunocompetent Patient.

During the coronavirus 2019 (COVID-19) pandemic, sundry dermatological conditions related to COVID-19 pneumonia have been published. COVID-19 primarily affects the respiratory system, but secondarily it also affects the heart, kidney, brain, skin, spinal cord, etc. Herpes Zoster (HZ) is considerably important morbidity associated with COVID-19 pneumonia. Recrudescence of HZ occurs because of the latent varicella-zoster virus (VZV) predominantly because of the decline in cell-mediated immunity (CMI). Abating CMI is due to the increasing age, but could also occur if the patient is suffering from an immunosuppressive disease or is using immunosuppressive drugs. In our case, the patient had no lymphopenia unlike the other cases, yet still, he developed HZ. HZ is associated with post-herpetic neuralgia (PHN), HZ ophthalmicus (HZO), and cerebral arteritis increasing morbidity and mortality, especially in elderly people and those who are immunocompromised.

Delayed Diagnosis of Neck Pain: Eagle Syndrome.

Eagle syndrome is a rare condition characterized by an abnormally elongated styloid process with or without abnormal direction and/or ossification of the styloid ligament. Clinically, it consists of throat and neck pain radiating to the ear. Here, we present the case of a 34-year-old female with the complaint of left-sided neck pain below the ear for the past year. The patient had tried different analgesics after seeing different doctors, but the pain did not resolve. After conducting radiological investigations at the hospital, a diagnosis of Eagle syndrome was made. The patient was treated with surgical styloidectomy, followed by subsequent remission of the symptoms.

Antibiomania: A Rare Case of Metronidazole-Induced Mania.

Metronidazole is a very commonly used drug for the treatment of ailments caused by bacteria and parasites. It can treat a vast array of conditions like rosacea, sexually transmitted diseases (STDs), liver abscess, bedsores, etc. Metronidazole comes with generic side-effects like nausea, vomiting, dizziness, metallic taste, and also rare side-effects like paresthesia, syncope, cerebellar symptoms, psychosis but mania is a rare side-effect. Here, we present a case of metronidazole induced mania in a 50-year-old male with no past medical history who initially presented with a complaint of mild fever, loss of appetite, and fatigue from the past 10-12 days. On further examination and investigations, diagnosis of the amebic liver abscess was made on the basis of USG, serum serology for amebiasis IgG, and a CT scan. Consequently, the patient was started on the drug of choice for amebic liver abscess; IV metronidazole 1.5g/day divided over the day into three doses. Other drugs that were administered were pantoprazole, paracetamol, and ondansetron. On the ninth day of admission, the patient's wife as well as the physician-daughter of the patient reported a change in the behavior of the patient which became a major concern for the family. The patient was restless, energetic, unable to sleep, had racing thoughts, elated mood, petulant, and kept singing loudly in the private patient room. There was no history of any psychiatric illness in the family. Mr. K´s manic symptoms were managed using haloperidol and lorazepam. Upon discontinuing metronidazole, there was a gradual improvement in the manic symptoms, and symptoms improved, haloperidol and lorazepam were able to be tapered down and eventually stopped. Mr. K did not require any use of any selective serotonin reuptake inhibitor (SSRIs), monoamine oxidase inhibitors (MAOIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), or any other atypical psychotropic drug. Manic-psychosis side-effect is a rare entity caused by antibiotics and the symptoms of which would disappear in a few days after stopping the antibiotic. It is also notable that this patient recovered without the use of any psychotropic drugs. Physicians should be aware of the possible neuropsychiatric side-effects of antibiotics which can lead to unnecessary workup. This side-effect did not require the use of any psychotropic drugs in this patient.
