Toxic shock syndrome (TSS) is a condition caused by bacterial toxins. Symptoms may include fever, rash, skin peeling, and low blood pressure. There may also be symptoms related to the specific underlying infection such as mastitis, osteomyelitis, necrotising fasciitis, or pneumonia.TSS is typically caused by bacteria of the Streptococcus pyogenes or Staphylococcus aureus type, though others may also be involved. Streptococcal toxic shock syndrome is sometimes referred to as toxic-shock-like syndrome (TSLS). The underlying mechanism involves the production of superantigens during an invasive streptococcus infection or a localized staphylococcus infection. Risk factors for the staphylococcal type include the use of very absorbent tampons, and skin lesions in young children characterized by fever, low blood pressure, rash, vomiting and/or diarrhea, and multiorgan failure. Diagnosis is typically based on symptoms.Treatment includes intravenous fluids, antibiotics, incision and drainage of any abscesses, and possibly intravenous immunoglobulin. The need for rapid removal of infected tissue via surgery in those with a streptococcal cause, while commonly recommended, is poorly supported by the evidence. Some recommend delaying surgical debridement. The overall risk of death is about 50% in streptococcal disease, and 5% in staphylococcal disease. Death may occur within 2 days.In the United States, streptococcal TSS occurs in about 3 per 100,000 per year, and staphylococcal TSS in about 0.5 per 100,000 per year. The condition is more common in the developing world. It was first described in 1927. Due to the association with very absorbent tampons, these products were removed from sale.
Current treatment standards include the starting of a bisphosphonate to reduce future fracture risk by up to 50%. Epidemiology
Hip fractures are seen globally and are a serious concern at the individual and population level. By 2050, it is estimated that there will be six million cases of hip fractures worldwide. One study published in 2001 found that in the US alone, 310,000 individuals were hospitalized due to hip fractures, which can account for 30% of Americans who were hospitalized that year. Another study found that in 2011, femur neck fractures were among the most expensive conditions seen in US hospitals, with an aggregated cost of nearly $4.9 billion for 316,000 inpatient hospitalizations. Rates of hip fractures are declining in the United States, possibly due to increased use of bisphosphonates and risk management. Falling, poor vision, weight, and height are all seen as risk factors. Falling is one of the most common risk factors for hip fractures. Approximately 90% of hip fractures are attributed to falls from standing height.Given the high morbidity and mortality associated with hip fractures and the cost to the health system, in England and Wales, the National Hip Fracture Database is a mandatory nationwide audit of care and treatment of all hip fractures. Population
All populations experience hip fractures but numbers vary with race, gender, and age. Women have three times as many hip fractures as men. In a lifetime, men have an estimated 6% risk whereas postmenopausal women have an estimated 14% risk of having a hip fracture.
