A case of herpetic rash in an immunocompetent patient is described, which was present in multiple dermatomes at the same time. First, patient was thought to have immunodeficiency, but further workup turned out to be negative for it. ⋯ Later, the patient responded well to the acyclovir therapy and was discharged home without any sequel. This case illustrates the need for emergency physicians to be extra vigilant for involvement of other dermatomes in case a patient presents with herpetic rash in 1 dermatome because patients with multidermatomal/disseminated herpetic rash need to be started on airborne isolation in addition to contact precautions to prevent the transmission of disease in health care settings.

Traditionally, intracranial pressure is measured by direct ventriculostomy, which is invasive. Noninvasive measures such as bedside ultrasound and magnetic resonance imaging have been advocated and utilized recently to assess the intracranial pressure. The role of this study is to determine the degree of agreement between measurements of the optic nerve sheath diameter by computed tomography (CT) and magnetic resonance imaging (MRI). ⋯ Comparable results without significant discrepancy as predetermined by the study groups were obtained from CT scan. Measurement of ONSD by CT scan can be used to indirectly asses the intracranial pressure in addition to clinical assessment and other signs of increased intracranial pressure on CT scan.

Case Reports
A unique presentation of renal cell carcinoma: both upper and lower gastrointestinal bleeding.
Renal cell carcinoma (RCC) constitutes 3% of all adult malignancies and may present with various symptoms due to local growth, metastasis, and paraneoplastic syndrome. Gastrointestinal hemorrhage because of RCC is a very rare event and more commonly seen as a recurrence of RCC many years after nephrectomy. Both upper and lower gastrointestinal bleeding due to direct invasion of RCC has not been reported yet in the literature. Herein, we report a case of 78-year-old man with both massive upper and lower gastrointestinal bleeding as a presenting symptom of RCC.

Case Reports
Anaphylaxis followed by unilateral lung opacity and hypocomplementemia in a young female.
A 36-year-old woman was stung in the right wrist by a bee, suffered typical anaphylaxis, and was transferred to a local hospital. After a few hours, which corresponded to late-onset reaction, she developed shortness of breath and weakness and was transferred to the emergency department, where the diagnosis of anaphylaxis was confirmed. Serum complement levels, components C3 and C4, were undetectable. ⋯ The most likely explanation is a very rare case of airway obstruction. To our knowledge, this is the only reported case of anaphylaxis associated with undetectable serum complement levels. The potential role and diagnostic significance of hypocomplementemia in cases of anaphylaxis should be further investigated.
