Cervical trauma in children: Be aware of the risk of infection.

Neck abscesses after a cervical trauma rarely occur, especially in children. Cervical abscesses are more generally complications of otolaryngological infections. Progression to severe complication or death may be rapid. We describe a case of a sternocleidomastoid muscle and retropharyngeal abscess that developed after a minor cervical trauma from being struck in the neck. The patient was surgically treated and received antibiotics, but returned with a recurrence of the cervical infection. We discuss the superinfection of the hematoma, cervical abscess management, and its treatment in children.

Pneumococcal Pyomyositis of the Neck Muscles.

High fever, severe neck pain and neck stiffness can result from meningitis. We report a case of pneumococcal pyomyositis of the neck muscles. A 72-year-old man developed high fever and severe neck pain. His chief complaint mimicked bacterial meningitis. Although his condition was initially suspected to be bacterial meningitis, his cerebrospinal fluid did not show pleocytosis. MRI showed areas of high intensity in the posterior deep neck muscles on short tau inversion recovery (STIR) sequences and gadolinium-enhanced T1-weighted images. Pneumococcal myositis should therefore be included in the differential diagnosis of severe neck pain with fever.

Metastatic muscle abscesses complicating infected total hip arthroplasty.

A 73-year-old woman with rheumatoid arthritis presented to our institution with infection of her right total hip arthroplasty. On admission, a draining sinus tract over the hip and a palpable mass in the left lower posterior region of the neck were detected. The contrast CT scan showed a large abscess in the trapezius muscle and multiple abscesses involving muscle of the neck and right shoulder. Intraoperative specimens from the muscle abscess were positive for presumably the same methicillin-resistant Staphylococcus aureus that sustained the prosthetic joint infection. Prolonged intravenous daptomycin led to remission of the muscle abscess and control of the prosthetic joint infection. The patient refused revision total hip arthroplasty and oral cotrimoxazole was prescribed for chronic suppression of the infection. Three years after the primary surgery there was stable remission of the prosthetic joint infection. This rare case demonstrates the severity of prosthetic joint infections sustained by multiresistant bacteria in immunocompromised hosts, which may result in their bacteraemic spread.

Sternocleidomastoid pyomyositis.

INTRODUCTION: Pyogenic myositis (pyomyositis) represents a bacterial infection of striated muscle. Predominantly associated with tropical regions and commonly caused by Staphylococcus aureus, the incidence of cervical pyomyositis is rare. To our knowledge, we report the first case of group A streptococcal cervical pyomyositis in an immunocompetent British Caucasian patient. CASE PRESENTATION: A previously well 48-year-old Caucasian male presented with sore throat, left sided neck pain and swelling. He was a lifelong non-smoker with no recent travel or animal exposure. On admission, he was febrile with unilateral neck swelling. Random blood glucose was normal and an HIV test negative. CT imaging confirmed a large heterogeneous mass extending throughout the entirety of the left sternocleidomastoid muscle. The patient underwent exploration and drainage of a large intra-sternocleidomastoid neck abscess. Microbiology identified group A - streptococcus. Histology confirmed abscess formation in muscle with no acid-fast bacilli. The patient recovered well postoperatively and continues to do well. DISCUSSION: Cervical pyomyositis is a rare condition that if not treated appropriately may cause internal jugular vein thrombosis, sepsis and death. Pyomyositis requires a high index of suspicion and should be considered a differential diagnosis in any painful swelling in the head and neck region.

Sudden myositis of the posterior cervical muscular compartment. Case report.

An atypical case of deep neck infection is presented with muscular involvement as the main feature. Streptococcus pyogenes was the causal agent and abrupt haemodynamic impairment and severe systemic failure characterized its clinical course, requiring emergency surgical examination and subsequent admission to the critical care unit. After the diagnosis of streptococcal myositis was obtained and the antibiotic treatment adjusted, the patient progressively recovered completely.

[Therapeutic management of necrotizing neck infections]. / Therapeutisches Management nekrotisierender Weichteilinfektionen des Halses.

BACKGROUND: Necrotizing neck infections are uncommon soft-tissue infections, usually caused by virulent, toxin producing bacteria. Necrotizing fasciitis represents a special form of necrotizing soft tissue infection with a mortality rate of up to 76% even though aggressive therapy is recommended. PATIENTS AND METHODS: In the last 2 years we treated four patients with severe necrotizing neck infections and five suffering from necrotizing fasciitis. RESULTS: Microbiological analysis revealed mixed infections with Candida albicans, Streptococcus pyogenes, Fusobacterium, Proprioni bacteria and Staphylococcus. The surgical management was not only restricted to drainage, but also included functional neck dissection in order minimize the spread of the disease. Eight of our patients recovered completely, but one died due to toxic shock as consequence of a delayed in therapy. CONCLUSION: Complete recovery of patients suffering from necrotizing fasciitis depends on early and aggressive surgical therapy including neck dissection and drainage as well as an interdisciplinary strategy of conservative therapy. Hyperbaric oxygen should be considered as a treatment adjunct in patients with necrotizing fasciitis if surgery and antibiotic treatment fail.

Postanginal septicaemia with external jugular venous thrombosis: case report.

Postanginal septicaemia is a syndrome of anaerobic septicaemia, septic thrombophlebitis of the internal jugular vein, and metastatic infections, that follows a localized infection in the area drained by the large cervical veins. The syndrome was well-known and often fatal in the preantibiotic era. It is now rather rare, presumably as a result of the almost routine use of prophylactic antibiotics. The symptoms are classic, and it should be suspected in any case where septicaemia and metastatic lesions are preceded by a head and neck infection. We report a case that is typical, except that branches of the external jugular vein were thrombosed. To our knowledge this has not been reported previously.

Cervical necrotizing fasciitis.

Necrotizing fasciitis is a severe soft tissue infection that results in necrosis of the fasciae and subcutaneous tissues; the infection can quickly prove fatal. Although involvement of the head and neck is rare, causes are usually odontogenic or pharyngeal but can also be insect bites, local trauma, burns or surgery. We present a clinical case of a 31-year-old Italian woman with cervical necrotizing fasciitis having an uncommon presentation. While under treatment, the patient's husband was admitted for necrotizing fasciitis of the medial fasciae of his left leg subsequent to an insect sting. The causes, diagnosis and treatment of necrotizing fasciitis are reviewed.
