Vertebral osteomyelitis is an infection of the vertebrae that can lead to spinal degeneration, most commonly caused by Staphylococcus aureus Here, we report an unusual case of pyogenic osteomyelitis caused by Gardnerella vaginalis and Streptococcus parasanguinis in a 61-year-old postmenopausal woman. The patient presented with a 2-week history of worsening lower back pain and fever and a recent episode of cystitis following re-engagement of sexual activity. Imaging revealed a deterioration of vertebrae discs and spinal canal stenosis at the L3-L4 levels with a formation of abscess in the right psoas muscle. Needle aspiration of the abscess identified G. vaginalis and S. parasanguinis and the patient was successfully treated with a 6-week course of ceftriaxone and metronidazole. This case describes an unusual coinfection of two pathogens that normally reside in the urogenital tract and oral cavity, respectively, and highlights the risk posed when these organisms breach the body's normal barriers., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

A Morel-Lavallée lesion (MLL) is a rare injury caused by blunt force trauma causing separation of subcutaneous tissue from the deep fascia. It is frequently seen in orthopaedic cases involving fractures of the hip or pelvis but is rare in the lower leg. The rarity of this condition often leads to misdiagnosis. A 66-year-old man presented to the emergency department after a 300-pound safe sheered across his left anterolateral leg causing skin avulsion, tenderness, swelling, ecchymosis, and erythema. The patient was treated for suspected cellulitis with oral antibiotics, but the lesion evolved into a necrotic eschar necessitating surgical intervention. In hindsight, MLL is a more appropriate diagnosis based on injury mechanism, disease progression and intraoperative findings. A history of shearing trauma with diffuse ecchymosis and erythema should prompt consideration of MLL. Due to rampant misdiagnosis, this case aims to increase awareness, as early diagnosis of MLL will improve patient outcomes., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

A 21-year-old young man with no history of diabetes or thyroid disease presented to the emergency department with simultaneous thyroid storm and diabetic ketoacidosis. Notable findings on admission were a ventricular rate of 235 beats/min, tachypnoea, tremors, polydipsia and a lack of fever. Due to the unusual constellation of symptoms, diagnosis was only possible after initial laboratory results came back. While the lack of fever is unusual in thyroid storm, diabetic ketoacidosis has previously been reported to suppress fever, and this case supports the occurrence of this phenomenon. This case was highly unusual because the patient had not previously been diagnosed with either type 1 diabetes or Graves' disease., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.
