Cervical necrotizing fasciitis (CNF) is a rapidly spreading deep neck infection with a high mortality rate if left untreated. The occurrence of necrotizing infections in the head and neck region is uncommon; therefore, it is a rare cause of chest pain presenting to the emergency department. Here, we present an interesting case of fungal cervical skin abscess complicated by necrotizing fasciitis that progressed to involve the mediastinum, causing necrotizing mediastinitis with pneumomediastinum in an elderly female. The patient presented to the emergency department with chest pain, shortness of breath, and fever. She had a 10-day history of a mass in the anterior midline of her neck with odynophagia. After radiologic confirmation, she was taken to the operating room where she underwent incision and drainage with debridement and washout. Postoperatively, she was given broad-spectrum antibiotics empirically, which were later replaced with intravenous (I/V) fluconazole after culture reports. Prompt diagnosis and treatment lead to the early recovery of the patient and subsequent discharge without any complications. We report this case to draw the attention of emergency medicine physicians and clinicians to this rare and life-threatening but treatable condition. Expeditious diagnosis and treatment lead to early recovery and fewer postoperative complications.

Metformin-associated lactic acidosis (MALA) is a potentially lethal condition that can result from the use of metformin in the setting of the risk factors such as renal insufficiency or hypoperfusion. We present a case of metformin-associated lactic acidosis incited by pyelonephritis-induced septic shock where use of continuous renal replacement therapy (CRRT) led to good recovery. A 51-year-old female with confusion and abdominal pain was brought to the emergency department (ED). She had a significant past medical history of type ll diabetes mellitus and recurrent urinary tract infections. Prior to the arrival to the hospital, she was conscious but confused and noted to have a low blood glucose level, which was managed with glucose per orally by emergency medical services. While in ED patient was dehydrated and hemodynamically unstable. She failed to respond to intravenous fluids hence vasopressors along with ceftriaxone were initiated. Intubation for mechanical ventilation was performed for respiratory failure and evolving septic shock, sodium bicarbonate for severe metabolic acidosis was started and antibiotics were stepped up to vancomycin and cefepime. The patient was transferred to the medical intensive care unit. Her kidney function continued to worsen, and she remained profoundly acidotic despite aggressive measures. A diagnosis of concomitant MALA was made since vasopressor requirement was less than expected considering the severity of acidosis. Emergent CRRT was initiated, resulting in improvement of acidosis in 24 hours. After she was stabilized vasopressors were stopped, she was extubated, and antibiotics were de-escalated to the oral regimen. MALA is rare but life-threatening complication of metformin use, especially in critically ill patients. CRRT should be considered as the first line in the treatment of metformin-related lactic acidosis, especially in the setting of hemodynamic instability.

We report a case of numb chin syndrome (NCS) that preceded the diagnosis of Burkitt's lymphoma (BL) and discuss our findings with emphasis on metastatic malignancies in general and BL in particular causing NCS. A 73-year-old woman presented with worsening right-sided back pain for a week along with right-sided leg weakness and a progressive thigh and perianal numbness. She reported numbness of the chin which started two weeks prior. MRI showed compression of the cauda equina which was highly suggestive of neoplastic process. After debulking mass surgery, biopsy of the tissue from spine revealed BL. The patient received a round of radiotherapy of spine and multiple rounds of chemotherapy. Six months later she had reoccurrence of lymphoma with metastasis and eventually passed away. Presence of NCS in the setting of an underlying malignancy indicates very poor prognosis. In appropriate clinical setting, NCS should trigger work up for an underlying malignancy.

Transient spinal shock is a previously unreported complication of intrathecal contrast. A 63-year-old man presented with the chief complaint of worsening back pain. Computed topography of lumbar spine without contrast showed a lytic lesion. After international normalized ratio (INR) correction, patient was sent for CT myelogram. After intrathecal contrast injection, the patient dropped his blood pressure profoundly and developed clinical manifestations of spinal shock. Emergent intravenous bolus fluids were initiated resulting in improvement in blood pressure. Patient’s spinal shock resolved within hours. CT myelogram was normal except previously known lytic lesion. It was concluded that the transient shock was most likely due to contrast injection. We believe that this is the first reported case of transient spinal shock following CT myelogram using water-soluble iodinated non-ionic contrast agent administered intrathecally.
