An Interesting Presentation of Pneumomediastinum Secondary to Hyperemesis Gravidarum in the Second Trimester.

We present a rare case of pneumomediastinum in the setting of hyperemesis gravidarum. Pneumomediastinum is a condition characterized by the presence of air leaking into the mediastinum. Often secondary to trauma, there remains the potential for it to develop spontaneously. This is a time-sensitive diagnosis that requires vigilance for effective treatment. A 21-year-old gravida 1 para 0 female at 15 weeks of gestation with no significant past medical history presented to the emergency department complaining of four weeks of daily nausea and vomiting and two weeks of chest pain, cough, and difficulty breathing. Computed tomography angiography of the chest revealed the presence of subcutaneous air in the mediastinum, and esophageal rupture was ruled out by a gastrografin esophagram. Due to extensive pneumomediastinum and severe metabolic derangements, the patient was admitted to the intensive care unit. A gastrografin esophagram was obtained, which showed no esophageal tear.No surgical intervention was performed, and she was managed with conservative treatment. This case illustrates some of the severe complications of pregnancy. Although pneumomediastinum secondary to hyperemesis gravidarum seen in this patient is rare (the incidence of pregnancy-related pneumomediastinum has been noted to be 1:100,000), it is an important adverse complication that the clinician should keep in mind in pregnant patients with hyperemesis gravidarum. Providing education to patients during the prenatal process can help identify the signs and symptoms of this condition to prevent potentially fatal consequences.

Acute Lower Lip Swelling: A Mere Anaphylactic Reaction or a Rare Abscess Location?

An abscess is a collection of pus secondary to an immune response to a pathogen. It can occur anywhere in the body, with the skin as the most common organ involved. A lip abscess is a rare condition. Generally, it may be due to an infective agent such as a virus or bacteria entering through a skin wound, or through hematogenous spread when there is a severe underlying condition such as a general condition disorder or immunodeficiency. It requires hypervigilance during the examination and throughout the treatment course with intravenous antibiotic therapy and urgent surgical drainage, as it may cause significant complications regarding localization, lymphovascular drainage, and ultimate spread. Persistent abscess, necrotic tissue, or cavitated lesions are worrisome and it is important to rule out immunosuppression or a methicillin-resistant staphylococcus. In this case, a 22-year-old male patient with a unilateral lip abscess, misdiagnosed as an allergic food reaction, responded well to external drainage and antibiotic therapy.
