BACKGROUND: Varicella is a very common childhood infectious disease. It is generally benign, but it can lead to fatal complications. Our study aimed to describe the clinical and therapeutic profile of varicella based on consultations in the pediatric emergency department, to determine the incidence of hospitalized varicella cases in the pediatric department for complementary management, and to specify the incidence of varicella complications in hospitalized patients.
METHODS: We conducted a retrospective descriptive cohort study over 12 months. It took place in the pediatrics and pediatric emergency departments of the Mother-Child Hospital of the Mohammed VI University Hospital, Mohammed I University, in Oujda, Morocco.
RESULTS: We collected 120 cases of varicella. The mean age of patients was 4.5 years. The most common age range was 4-6 years (69%). Males predominated. The reason for consulting the pediatric emergency department was a febrile rash in 65% of cases. Treatment in pediatric emergencies was mostly symptomatic. Antibiotic treatment for superinfection of lesions was used in 11% of cases. The number of hospitalizations due to complicated and/or severe varicella was 17 cases. The median age was 6.3 years. Most of the children (82%) were immunodeficient and 18% were immunocompetent. Sixteen patients had underlying risk factors. Infectious skin and soft tissue complications were noted in most hospitalized patients (47%). They were mainly presented by cutaneous reinfections with alteration of general health (41%). Neurological complications ranked second (23%). The majority were febrile convulsions (17%). One case of bronchopulmonary complication was noted. No hematological, digestive, renal, or cardiac complications were noted. Intravenous antiviral treatment was used in 88% of hospitalized cases. The drug of choice was acyclovir. Antibiotic therapy was used in 53% of cases. No patient received corticosteroid therapy. The median length of hospitalization for our patients was 14 days. The evolution was favorable in 100% of cases.
CONCLUSIONS: Varicella remains a benign disease in children, rarely leading to hospitalization. However, complications may develop in cases of comorbidity or children with risk factors. The introduction of the varicella vaccine into the national immunization program could considerably reduce the number of children hospitalized in the near future.

A polymorphous recurrent eruption mostly composed of macules, bullae, papules, and target lesions, which are often distributed symmetrically and can spread to distant extremities, and oral mucosae are the features associated with erythema multiforme (EM). Herpes simplex virus (HSV) is a common condition that is associated with EM and manifests in late adulthood. It shows recurrence and is usually diagnosed clinically. Following is a case of HSV-associated EM. A 45-year-old patient visited the outpatient department with complaints of oral ulceration and associated pain and burning sensation. The patient also reported that similar ulcers were seen two months prior to her visit, which resolved on their own and the recurrence was seen two days prior to the visit. The recurrence occurred with more severity of pain and inflammation as compared to previous ulcers. The patient was kept on a combination therapy of antivirals, steroids, silymarin, and multivitamins for four visits with a tapering dose of steroids. Post-treatment, there was no recurrence till date and the patient is able to perform mastication as well as deglutition without any pain or burning sensation.

Epstein-Barr virus (EBV) is a widely infectious pathogen affecting most of the global population at some point in their life. While, typically, primary infections are subclinical, chronic persistence of the virus due to T-cell proliferation can cause severe complications. Acute hepatitis due to chronic active EBV (CAEBV) has rarely been documented. This case details a previously healthy 81-year-old woman who presented with complaints of diffuse abdominal pain, nausea, and vomiting. Her diagnostic workup demonstrated an EBV infection with worsening thrombocytopenia, transaminitis, and hepatocellular liver injury with acute ascites. Her hospitalization was resistant to the traditional supportive treatment of EBV, requiring intensive care management and unorthodox therapy. Although antivirals have demonstrated limited utility in the treatment of CAEBV, the severity of her illness and refractory hospital course necessitated the use of acyclovir. She made a complete recovery with no deficits. The case demonstrates the presentation of acute hepatitis and ascites as a result of CAEBV, the clinical sequelae, and acyclovir as a potential new treatment option.

Trigeminal neuralgia (TN) is characterized by episodic electric, shock-like facial pain. Though often idiopathic, herpes simplex virus type 1 (HSV-1) reactivation can rarely cause symptomatic TN. We report the case of a 30-year-old woman who developed oral HSV-1 lesions followed by right-sided TN pain. MRI of the brain did not reveal neurovascular compression. TN pain completely resolved with oral acyclovir treatment alone, without anticonvulsants. This highlights the importance of considering atypical etiologies such as HSV-1 reactivation in TN evaluation. Early antiviral therapy may treat underlying inflammation and provide sustained symptom relief in HSV-associated TN.
