We report a case of a patient who presented for ACTH‐dependent Cushing after a confirmed hypercortisolism and an inadequate normal ACTH. A transsphenoidal surgery of a pituitary picoadenoma has been done. After surgery, the patient showed the persistence of hypercortisolism. CT scan revealed adrenal adenomas removed surgically and improved the patient. 相似文献
We estimate the prevalence and type of urinary incontinence (UI), possible associated risk factors, and the impact of UI on women's social and psychological well-being. The sample consisted of women attending a family medicine clinic at Jordan University Hospital (JUH) who answered a self-administered questionnaire. More than one-third of the sample reported the presence of UI. Stress type was the most frequently reported risk factor, followed by mixed incontinence, then urge. Age, diabetes, chronic cough, parity, and hysterectomy were positively associated with the presence of UI. Incontinence caused low self-esteem in more than half of the women who experienced it. 相似文献
Perineuriomas are rare benign soft tissue tumors having an immunophenotype paralleling the normal perineurial cell [S-100 protein negative and epithelial membrane antigen (EMA) positive]. Because EMA expression in perineuriomas may be focal and/or faint, there is continued interest in the development of new markers of perineurial differentiation. Perineurial cells differ from almost all other mesenchymal cell types by virtue of their formation of tight junctions. In the course of evaluating a group of novel tight junction-associated proteins, we noted high levels of expression of claudin-1 by normal perineurial cells and have systematically extended these observations to perineuriomas. Twelve EMA-positive/S-100-negative perineuriomas were retrieved from our consultation archives and compared with 39 tumors in the differential diagnosis of perineurioma (seven dermatofibrosarcoma protuberans, eight low-grade fibromyxoid sarcomas, three desmoplastic fibroblastomas, seven fibromatoses, nine neurofibromas, and five schwannomas). All cases were immunostained for claudin-1 using standard avidin-biotin technique. Cases were scored as 3+ (>50% positive cells), 2+ (25-50% positive cells), and 1+ (5-24% positive cells). In all cases positive internal controls in the form of epithelium, normal perineurium, or endothelial cells were present. Positive staining for claudin-1 was visualized in a distinctly particulate pattern along the cell membrane. Cytoplasmic staining was infrequent and was not scored as positive. Claudin-1 expression was present in 11 of 12 (92%) perineuriomas studied (seven at 3+, three at 2+, and one at 1+). In all but two cases, the degree of claudin expression was equal to or greater than the corresponding EMA immunostain. Claudin-1 expression was not noted in any cases of dermatofibrosarcoma protuberans, low-grade fibromyxoid sarcoma, desmoplastic fibroblastoma, or fibromatosis. Six of nine cases of neurofibroma contained a significant number of claudin-1-positive cells that were thought to be perineurial in origin, based on the staining of long, delicate cytoplasmic processes. One of four schwannomas contained a subpopulation of perivascular, dendritic, claudin-1-positive cells of presumed perineurial lineage. This is the first study to document expression of claudin-1 in perineurial cells and suggests a role for claudin-1 immunohistochemistry in the diagnosis of perineuriomas. Although claudin-1 should not replace EMA in the diagnosis of perineurioma, we think that it may play a valuable adjunctive role in difficult cases. In particular, claudin-1 is often a more robust marker than EMA in a given perineurioma. Claudin-1 is not expressed within the lesional cells of the mesenchymal tumors that enter into the differential diagnosis of perineurioma. 相似文献
The American Cancer Society provides estimates on the number of new cancer cases and deaths, and compiles health statistics on African Americans in a biennial publication, Cancer Facts and Figures for African Americans. The compiled statistics include cancer incidence, mortality, survival, and lifestyle behaviors using the most recent data on incidence and survival from the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) program, mortality data from the National Center for Health Statistics (NCHS), and behavioral information from the Behavior Risk Factor Surveillance System (BRFSS), Youth Risk Behavior Surveillance System (YRBSS), and National Health Interview Survey (NHIS). It is estimated that 132,700 new cases of cancer and 63,100 deaths will occur among African Americans in the year 2003. Although African Americans have experienced higher incidence and mortality rates of cancer than whites for many years, incidence rates have declined by 2.7 percent per year in African-American males since 1992, while stabilizing in African-American females. During the same period, death rates declined by 2.1 percent and 0.4 percent per year among African-American males and females, respectively. The decrease in both incidence and death rates from cancer among African-American males was the largest of any racial or ethnic group. Nonetheless, African Americans still carry the highest cancer burden among US racial and ethnic groups. Most cancers detectable by screening are diagnosed at a later stage and survival rates are lower within each stage of disease in African Americans than in whites. The extent to which these disparities reflect unequal access to health care versus other factors is an active area of research. 相似文献
Objective: Small for gestational age (SGA) fetuses are at increased risk of admission to the neonatal unit, even at term. We aimed to develop and validate a predictive model for the risk of prolonged neonatal unit admission in suspected SGA fetuses at term.Methods: A single-center cohort study of singleton pregnancies with SGA fetus, defined as estimated fetal weight (EFW) less than the 10th centile, at term. The variables included known risk factors for neonatal unit admissions: maternal characteristics, EFW, abdominal circumference (AC), fetal Dopplers, gestational age (GA) at delivery, and intrapartum risk factors (meconium, pyrexia). Logistic regression analysis was used for model building and the prediction models were validated internally using bootstrapping.Results: Seven hundred and one SGA pregnancies at term were included; 5.9% had prolonged neonatal unit admission (>48?h). The multivariable model (AUC 0.71; 95% CI: 0.63–0.79) included GA at delivery <39 weeks (OR 2.76; 95% CI 1.23–6.04, p?=?.011), cerebroplacental ratio (CPR) multiples of median (MoM) (OR 0.21; 95% CI 0.05–0.79, p?=?.023), and EFW below the third centile (OR 2.43; 95% CI 1.26–4.68, p?.007). The combined model showed a sensitivity 30.9% (95% CI: 16.6–45.2%) for a fixed 10% false positive rate.Conclusion: The prediction model shows good accuracy and good calibration for assessing the risk of neonatal unit admission in suspected SGA fetuses. It has the potential to be used for patient counseling, determining the timing of delivery and the individual risk.
Brief rationale
Objective: The objective of this study is to determine the factors associated with prolonged neonatal unit admissions in small for gestational age fetuses at term.
What is already known: Fetal weight and Doppler parameters are associated with adverse outcome in small for gestational age fetuses. However, most studies use composite outcome criteria by combining neonatal unit admission with adverse delivery outcomes. A comprehensive model combining antenatal and intrapartum variables is also lacking.
What this study adds: Our model describes the association of antenatal and intrapartum variables with prolonged neonatal unit admission without using a composite adverse outcome measure. Estimated fetal weight, gestational age at delivery, and the cerebroplacental ratio can be used to estimate the risk of prolonged neonatal unit admission. The risk estimation can be useful for patient counseling and to determine the time of delivery.
Each year, the American Cancer Society estimates the number of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival based on incidence data from the National Cancer Institute and mortality data from the National Center for Health Statistics. Incidence and death rates are age-standardized to the 2000 US standard million population. A total of 1,372,910 new cancer cases and 570,280 deaths are expected in the United States in 2005. When deaths are aggregated by age, cancer has surpassed heart disease as the leading cause of death for persons younger than 85 since 1999. When adjusted to delayed reporting, cancer incidence rates stabilized in men from 1995 through 2001 but continued to increase by 0.3% per year from 1987 through 2001 in women. The death rate from all cancers combined has decreased by 1.5% per year since 1993 among men and by 0.8% per year since 1992 among women. The mortality rate has also continued to decrease from the three most common cancer sites in men (lung and bronchus, colon and rectum, and prostate) and from breast and colorectal cancers in women. Lung cancer mortality among women has leveled off after increasing for many decades. In analyses by race and ethnicity, African American men and women have 40% and 20% higher death rates from all cancers combined than White men and women, respectively. Cancer incidence and death rates are lower in other racial and ethnic groups than in Whites and African Americans for all sites combined and for the four major cancer sites. However, these groups generally have higher rates for stomach, liver, and cervical cancers than Whites. Furthermore, minority populations are more likely to be diagnosed with advanced stage disease than are Whites. Progress in reducing the burden of suffering and death from cancer can be accelerated by applying existing cancer control knowledge across all segments of the population. 相似文献
