Quality of life determinants and hearing function in an elderly population: Osservatorio Geriatrico Campano Study Group.

Abstract: Background: Hearing impairment (HI) is a very common condition in elderly people and the epidemiology together with hearing-related problems is still poorly investigated. Moreover,

Effectiveness of auto‐cross‐linked hyaluronic acid gel in the prevention of intrauterine adhesions after hysteroscopic adhesiolysis: a prospective, randomized, controlled study

Abstract: BACKGROUND: A prospective, randomized, controlled study was performed to assess the efficacy of auto-crosslinked hyaluronic acid (ACP) gel to prevent the development of de-novo intrauterine adhesions following hysteroscopic surgery. METHODS: One hundred and thirty-two patients with a single surgically remediable intrauterine lesion (myomas, polyps and uterine septa, subgroups I-III) completed the study. Patients were randomized to two different groups: group A underwent hysteroscopic surgery plus intrauterine application of ACP gel (10 ml) while group B underwent hysteroscopic surgery alone (control group). The rate of adhesion formation and the adhesion score was calculated for each group and subgroup 3 months after surgery. RESULTS: Group A showed a significant reduction in the development of de-novo intrauterine adhesions at 3 months follow-up in comparison with the control group. Furthermore, the staging of adhesions showed a significant decrease in adhesion severity in patients treated with ACP gel. CONCLUSIONS: ACP gel significantly reduces the incidence and severity of de-novo formation of intrauterine adhesions after hysteroscopic surgery.

Diarrheal disease during Operation Desert Shield.

Abstract: Background. Under combat conditions infectious disease can become a major threat to military forces. During Operation Desert Shield, there were numerous outbreaks of diarrhea among the U.S. forces. To evaluate the causes of and risk factors for diarrheal disease, we collected clinical and epidemiologic data from U.S. troops stationed in northeastern Saudi Arabia. Methods. 432 military personnel who presented with diarrhea, cramps, vomiting, or hematochezia. In addition, a questionnaire was administered to 2022 soldiers in U.S. military units located in various regions of Saudi Arabia. Results. A bacterial enteric pathogen was identified in 49.5 percent of the troops with gastroenteritis. Enterotoxigenic Escherichia coli and Shigella sonnei were the most common bacterial pathogens. Of 125 E. coli infections, 39 percent were resistant to trimethoprim–sulfamethoxazole, 63 percent to tetracycline, and 48 percent to ampicillin. Of 113 shigella infections, 85 percent were resistant to trimethoprim–sulf...

Dopamine receptor expression and function in corticotroph pituitary tumors

Abstract: The role of dopamine agonist treatment in corticotroph pituitary tumors is controversial. The aim of this study was to evaluate D(2) receptor expression in 20 corticotroph pituitary tumors and to correlate it to the in vitro effect of dopamine agonists on ACTH secretion and the in vivo effect of short-term cabergoline treatment on cortisol secretion. D(2) expression was evaluated by receptor-ligand binding, immunohistochemistry, and RT-PCR. A 50% or more decrease in daily urinary cortisol levels was considered a significant clinical response. At receptor-ligand binding, specific binding of [(125)I]epidepride was found in 80% of cases. At immunohistochemistry, specific D(2) immunostaining was found in 75% of cases. D(2) expression was found in 83.3% of cases (D(2long) in 40%, D(2short) in 20%, and both in 40%) by RT-PCR. Significant in vitro inhibition of ACTH secretion was found in 100% of D(2)-positive cases, but not in 100% of D(2)-negative cases by either bromocriptine or cabergoline. A significant in vivo inhibition of cortisol secretion after 3-month cabergoline treatment was found in 60%, although a normalization of cortisol secretion was found in 40% of cases. All cabergoline-responsive cases were associated with D(2) expression, whereas all noncabergoline-responsive cases but one were not associated with D(2) expression. In conclusion, functional D(2) receptors were expressed in approximately 80% of corticotroph pituitary tumors. The effectiveness of cabergoline in normalizing cortisol secretion in 40% of cases supports its therapeutic use in the management of Cushing's disease.
