Role of ultrasound in the diagnosis of abdominal hydatid disease

Experience with the use of ultrasound for investigating hydatid disease of the abdomen is reported. The presence of daughter cysts within the parent cyst gives a pathognomonic sonographic picture, whether the cyst is single or multiple. The presence of single cysts without daughter cysts is still a diagnostic problem, unless calcification is seen. Associated secondary infection changes the picture to one of a nonspecific abscess, and only the presence of additional cysts can give a clue about the etiology.     

Mental health officers' causal explanations of combat stress reaction

This study examined causal attributions for combat stress reaction (CSR) among 117 Israel Defense Forces (IDF) mental health officers. The impact of case characteristics (the level of objective stress in the situation, reaction of others in the same situation, soldier's previous functioning, and type of symptomatology) and respondent characteristics (professional affiliation, therapeutic orientation) on these attributions was also examined. Results show that mental health officers view CSR primarily as a response to external circumstances; it is not generally seen as resulting from personality traits or intrapsychic processes. Findings also indicate that causal attributions were influenced at least to some degree by the clinicians' professional affiliation, their therapeutic orientation, and their knowledge of the casualty's prior functioning.     

Sebaceous Adenomas,Squamous Cell Carcinoma and Skin Infections in a Patient with Carcinoma of the Colon,Rectum and Bladder

Sebaceous adenomas and squamous cell carcinoma developed in a male patient in addition to viral, mycotic and bacterial infections, several years after the removal of three malignant tumors from his lower gastrointestinal and urinary tract. Skin tests with trichophytin, candidin, and mixed bacteria were negative. Various aspects regarding cutaneous changes associated with colorectal and bladder carcinomas are discussed.     

The right bronchial artery: Anatomical considerations and surgical approach

The precise course and relations of the right bronchial artery are presented with an emphasis on the characteristic parallelism between the arches of this artery and the azygos vein. The technique for an easy surgical approach to the bronchial artery is described. Various pathological conditions involving this artery are discussed in relation to possible surgical applications.     

Oscillating between denial and recognition of PTSD: Why are lessons learned and forgotten?

Consistent observations suggest that denial of PTSD and blaming of its victims are not isolated omissions or distortions but a pattern that spans over time, crosses national and cultural boundaries, and defies accumulated knowledge. This article traces the origins of these attitudes and offers three explanations: (a) mental health professionals are unable to transcend prevailing cultural and social norms; (b) they are blinded by professional theories; and (c) denial may stem from a fundamental human difficulty in comprehending and acknowledging our own vulnerability.     

Beliefs, risk perceptions, and gaps in knowledge as barriers to colorectal cancer screening in older adults

OBJECTIVES: To assess beliefs and perceptions of risk about colorectal cancer (CRC) and gaps in knowledge about screening in adults aged 65 to 89.
DESIGN: A population-based survey.
SETTING: United States.
PARTICIPANTS: A total of 1,148 respondents with no history of CRC, representing an estimated population of 31.6 million persons, who were stratified according to screening behavior (up to date (n=457) vs not up to date (n=691)) and age (65–74 vs 75–89).
MEASUREMENTS: The Health Information National Trends Survey (2003) questionnaire.
RESULTS: An estimated 25% of adults aged 65 to 89 had not heard of the fecal occult blood test, 17% had not heard of sigmoidoscopy or colonoscopy, and 42% were not up to date with either screening modality. Not visiting a healthcare provider in the previous year, not knowing about tests available for colon cancer, perceiving the arrangements to be checked for detecting colon cancer to be difficult, and not having an opinion about it and its cost, were significantly associated with not being up to date (each P <.03). Persons who were not up to date were frequently unaware of the importance of CRC screening, and often reported lack of a provider's recommendation to be screened (>75%). Lack of knowledge and awareness were more prevalent in those aged 75 to 89 than those aged 65 to 74.
CONCLUSION: Lack of knowledge and awareness and the absence of a physician's recommendation to be tested might explain not being up to date with CRC screening in adults in these age groups. These findings suggest a potential value for better communication between older adults and their providers regarding screening for CRC, when appropriate.     

Is terror gender-blind? Gender differences in reaction to terror events

Objective This study examines gender differences in posttraumatic vulnerability in the face of the terror attacks that occurred during the Al-Aqsa Intifada. In addition, the contribution of level of exposure, sense of safety, self-efficacy, and coping strategies is assessed. Method Participants were 250 men and 262 women, who constitute a representative sample of Israel's adult population. Data were collected via a structured questionnaire consisting of 51 items that were drawn from several questionnaires widely used in the study of trauma. Results The findings indicate that women endorsed posttraumatic and depressive symptoms more than men and that, generally, their odds of developing posttraumatic stress symptoms are six times higher than those of men. Results also revealed that women's sense of safety and self-efficacy are lower than men's and that there are gender differences in coping strategies in the face of terror. Conclusions Gender differences in vulnerability to terror may be attributable to a number of factors, among these are women's higher sense of threat and lower self-efficacy, as well as their tendency to use less effective coping strategies than men. Level of exposure to terror was ruled out as a possible explanation for the gender differences in vulnerability.
