Nontuberculous mycobacterial lung infections in patients with eating disorders: plausible mechanistic links in a case series.

Nontuberculous mycobacteria (NTM) are widely distributed in the environment and are almost always acquired into the lungs by bioaerosol inhalation or aspiration of NTM-contaminated water, biofilms, and soil. NTM are increasingly recognized as causes of lung diseases in immunocompetent hosts, a not insignificant number of whom have a life-long or nearly life-long slender body habitus as well as thoracic cage abnormalities such as scoliosis and pectus excavatum. While several hypotheses have been offered to explain the purported increase in susceptibility to NTM lung disease in such individuals, the precise explanation remains unknown.

Notalgia Paresthetica Relieved by Cervical Traction.

Notalgia paresthetica is a syndrome of unilateral, chronic pruritis that is associated with burning pain, paresthesia, numbness, and hyperesthesia localized to the medial and inferior scapula. The condition does not respond to anti-inflammatory drugs or traditional antipruritic agents and has variable responses to numerous other reported pharmacologic and nonpharmacologic therapies. Although the etiology is thought to be nerve impingement, neurologic and musculoskeletal causes are often not considered in the differential diagnosis.

Oxidative in vitro metabolism of liquiritigenin, a bioactive compound isolated from the Chinese herbal selective estrogen beta-receptor agonist MF101.

Liquiritigenin [2,3-dihydro-7-hydroxy-2-(4-hydroxyphenyl)-(S)-4H-1-benzopyran-4-one] is one of the major active compounds of MF101, an herbal extract currently in clinical trials for the treatment of hot flashes and night sweats in postmenopausal women. MF101 is a selective estrogen receptor beta agonist but does not activate the estrogen receptor alpha. Incubation with pooled human liver microsomes yielded a single metabolite.

Increase in normal placental weights related to increase in maternal body mass index.

Objective: Reference values of normal placental weights are many decades old. Recently, a trend of increasing weights of normal placentas has been noted. We aimed to confirm this observation and to find any associated fetal and maternal factors.

Barriers to osteoporosis identification and treatment among primary care physicians and orthopedic surgeons.

Objective: To understand better the barriers among orthopedic surgeons and primary care physicians in identifying and treating possible osteoporosis in patients hospitalized with a fragility fracture sustained spontaneously or from a fall no greater than standing height.

Methods: A 1-page, 7-question survey was sent to 35 admitting orthopedic surgeons and 75 primary care physicians at a midwestern managed care organization in March 2001. Returned surveys were collected until 30 days had passed since the mailing.
