Adenomyosis, the heterotopic presence of endometrial glands and stroma within the myometrium, has traditionally been diagnosed by the pathologist in hysterectomy specimens. However, the recent development of high-quality non-invasive techniques such as transvaginal sonography (TVS), magnetic resonance imaging (MRI) and hysteroscopy has renewed interest in diagnosing adenomyosis in the office prior to any treatment. Hysteroscopy offers the advantage of direct visualization of the uterine cavity, and since nowadays it is performed in the office, it can be offered as a first-line diagnostic tool for evaluation of uterine abnormalities in patients with abnormal uterine bleeding and/or infertility. The available data clearly indicate that high-quality mini-hysteroscopes, saline as a distension medium, and atraumatic insertion technique are essential for the success of office hysteroscopy. The procedure is indicated in any situation in which an intrauterine anomaly is suspected; it is immediately preceded by a physical exam and a TVS to evaluate uterine characteristics, and it is followed by a second TVS to take advantage of the intracavitary fluid for a contrast image of the uterus. Although diagnostic hysteroscopy does not provide pathognomonic signs for adenomyosis, some evidence suggests that irregular endometrium with endometrial defects, altered vascularization, and cystic haemorrhagic lesion are possibly associated with the entity. In addition to the direct visualization of the uterine cavity, the hysteroscopic approach offers the possibility of obtaining endometrial/myometrial biopsies under visual control. Since they can be performed in the office, the combination of TVS, fluid hysteroscopy and contrast sonography is therefore a powerful screening tool for detecting endometrial and myometrial abnormalities in association with adenomyosis.
The acquisition of the mec gene complex by methicillin-susceptible Staphylococcus aureus in the community and the increased spread of methicillin-resistant Staphylococcus aureus (MRSA) from the health care setting to the community underscore a need to monitor the resistance phenotypes likely to be encountered among outpatient MRSA. Data from the LEADER 2004 surveillance program were analyzed to evaluate current resistance profiles among outpatient MRSA. Outpatient MRSA exhibited 26 different resistance phenotypes; the 4 most common were resistance to erythromycin only (40.8%), multidrug resistance to erythromycin, clindamycin, and levofloxacin (21.5%), double drug resistance to erythromycin and levofloxacin (11.3%), and double drug resistance to clindamycin and erythromycin (5.1%). These phenotypes were also the most common among inpatient MRSA (n = 946), but multidrug resistance to erythromycin, clindamycin, and levofloxacin (43.7%) was most common. Fifty percent (256) of the outpatient MRSA were resistant to 2 or more agents, whereas resistance to either vancomycin or linezolid was not encountered. The extensive similarities in resistance profiles between inpatient and outpatient MRSA have important implications for establishing outpatient management and treatment guidelines for staphylococcal infections.
