Isolated Staphylococcal Infection of the Sternoclavicular Joint

In the present study, twenty atopic dogs were investigated for secondary skin infections using different diagnostic techniques. The majority of dogs were suffering from bacterial infections, especially Staphylococcal infection (90 %). Different commensals on skin like Staphylococcus spp., Aspergillus spp. (50 %), Malassezia spp. (45 %), Demodex spp. (25 %) etc. caused secondary or concurrent infections in many atopic dogs indicating the importance of atopy in recurrent or non-responding dermatitis with those commensal organisms.

BACKGROUND: Subacromial pain (SAP) is a common complaint of young athletes, independently of the sport engaged. The prevalence of SAP in some sports is up to 50%. OBJECTIVE: The study was aimed to investigate some new factors possibly associated to subacromial pain in young athletes. The factors considered were the grade of tightness of the clavicular portion of the pectoralis major, dysfunction of the sternoclavicular joint, and serratus anterior and lower trapezius strength. METHODS: This case-control study included 82 young athletes 9–15 years, 41 with the symptoms of SAP and 41 controls. All participants self-reported whether they had subacromial pain. In addition, Hawkins–Kennedy Test was performed to all the participants to evaluate the subacromial pressure. Main outcome measures were the grade of tightness of the clavicular portion of the pectoralis major, dysfunction of the sternoclavicular joint, and serratus anterior and lower trapezius strength. The grade of tightness of the clavicular portion of the pectoralis major and the dysfunction of the sternoclavicular joint were measured with an inclinometer. Serratus anterior and lower trapezius strength were measured by a handheld dynamometer with external belt-fixation. The data were analyzed using t-test for independent samples, Mann-Whitney U test, contingency coefficients and a stepwise binary logistic regression. RESULTS: Significant statistical difference was observed in the grade of tightness of the clavicular portion of the pectoralis major and in the variable representing the physiological functioning of the sternoclavicular joint, between the cases and the controls. There was no significant difference in serratus anterior and lower trapezius strength between the cases and the controls. Logistic regression analysis showed that the variable representing the physiological functioning of the sternoclavicular joint and the grade of shortening of the clavicular portion of the pectoralis major were good predictors for presence of SAP. CONCLUSIONS: A strong association was determined between subacromial pain in young athletes, clavicular portion of pectoralis major tightness and the dysfunction of the sternoclavicular joint.

Per Se

Staphylococcus-associated glomerulonephritis (SAGN) occurs as a complication of staphylococcal infection elsewhere in the body. Dermatomyositis (DM) can be associated with glomerulonephritis due to the disease per se. We report a case of a 40-year-old male patient with DM who presented with acute kidney injury, and was initially pulsed with methylprednisolone for 3 days, followed by dexamethasone equivalent to 1 mg/kg/day prednisolone. He was subsequently found to have SAGN on kidney biopsy along with staphylococcus bacteraemia and left knee septic arthritis. With proof of definitive infection, intravenous immunoglobulin 2 g/kg over 2 days was given and steroids were reduced. He was treated with intravenous vancomycin. With treatment, the general condition of the patient improved. On day 38, he developed infective endocarditis and died of congestive heart failure subsequently. Undiagnosed staphylococcal sepsis complicating a rheumatological disease course can lead to complications like SAGN, infective endocarditis and contribute to increased morbidity and mortality, as is exemplified by our case.
