Benign osteoblastoma of the occipital bone: Case report and literature review

We present a case of benign osteoblastoma of the occipital bone. Benign osteoblastoma is an uncommon primary bone tumor, which usually involves the vertebrae and the long bones. This tumor rarely develops in the calvaria, showing a preference for the temporal and frontal bones when it does. To the best of our knowledge, this case is only the eighth reported case of benign osteoblastoma confined to the occipital bone. A 20‐year‐old male presented with a mild tender mass lesion of the occipital area, just below the lambda. Plain X‐ray films and CT scans demonstrated an osteolytic mass surrounded by the sclerotic rim within the diploic space. MRI proved to be effective for the evaluation of the intracranial and intraosseous extensions of the tumor. However, it was very difficult to formulate a differential diagnosis against other osteoblastic tumors, or osteoid osteoma, in view of its radiological appearance. The final diagnosis was obtained by careful consideration of the histopathological characteristics of the tumor combined with its clinical and radiological features. Although generally regarded as benign, a complete resection is preferred over conventional curettage as this can guard against possible recurrence and malignant transformation.     

Self‐reflection and self‐practice in training of Cognitive Behaviour Therapy: an overview

The present paper deals with a developing training element in cognitive behaviour therapy (CBT), the self‐practice of therapeutic techniques and the self‐exploration of the person of the therapist. Initially, the current status of this training element in CBT is discussed, and a short note on its terminology is presented. Then an overview of the most important objectives of self‐practice and self‐reflection in CBT, and the concepts and methods of practice of this element is given. The concepts focus on two major aims, the self‐exploration of the person of the therapist within and beyond his or her therapeutic practice, and the self‐application of therapeutic techniques (= self‐practice). In the second part of the paper empirical studies related to the outcome of self‐reflection and self‐practice on the development of the therapist and her or his therapeutic practice are reviewed. The few empirical studies show that trainees experience in their own view substantial professional and personal gains from this training tool, with the professional impact being more important than the personal one. The most important outcomes evaluated by subjective data from the trainees are improvements in self‐insight and self‐awareness and a better understanding of the therapist's role and the therapeutic change process. Additionally, a better understanding of CBT methods and of general therapeutic skills, such as empathy and role‐taking‐competencies, are reported by the trainees. The paper comes to the conclusion that self‐exploration and self‐practice are important components of CBT training. Consequences and recommendations for its integration into training courses for CBT are discussed as well as the necessity for more research in this area.

INVASIVE MUCORMYCOSIS WITH GASTRIC INVOLVEMENT IN A PATIENT WITH SEVERE ATHEROMATOUS VASCULAR DISEASE

Gastric mucormycosis involvement is a rare condition that usually occurs in inmunocompromised patients and frequently has a fatal outcome. We report the case of a 73‐year‐old woman admitted to the intensive care unit with severe bleeding after an acute pulmonary disease. Upper endoscopy disclosed wide and deep necrotic ulcers in the body and fundus of the stomach and greenish exudates with the antrum and the duodenum undamaged. Autopsy revealed an invasive mucormycosis and a severe atheromatosis. Several predisposing factors for mucormycosis infection have been reported until now. We postulate that ischemic gastritis could be a predisposing factor for colonization of zygomycete.     

Hippocampal nerve growth factor levels are related to spatial learning ability in aged rats.

Brain nerve growth factor (NGF) was determined in two groups of aged rats: 'good' and 'poor' performers. The animals were selected out of a population of 40 aged rats (26-28 months old) trained in a spatial learning task. Animals performing well in the test had significantly higher NGF in the hippocampus when compared to 'poor' performers. No differences in the levels of NGF were found in the cortex, septum and cerebellum. The results implicate hippocampal NGF in cognitive functioning of aged rats, and suggests that the forebrain cholinergic neuronal atrophy which has been observed in cognitively impaired aged rats may be due to reduced availability of target-derived NGF.     

Non-Hodgkin's lymphoma with protein S deficiency]

Venous thrombosis is rare in children. It can be either acquired or of constitutional origin. Thrombosis during non-Hodgkin lymphoma remains exceptional and is usually locally associated to the tumoral process, raising the issue of its tumoral or cruoric nature. The treatment is based on anticoagulation concomitantly to chemotherapy. We report on a 4-year-old boy admitted for mediastinal non-Hodgkin lymphoma, who developed a thrombosis of the superior vena cava associated to protein S-deficiency. The mechanism of thrombosis may have been multifactorial: associated protein S-deficiency, vascular compression, tumoral process and chemotherapy.     

Mediating effects of social support on firefighters' sense of community and perceptions of care

This study examined the relationship between psychological sense of community, social‐support networks, and care‐giver stress and satisfaction among firefighters. No significant gender differences were obtained, but zero‐order correlates demonstrated significant relationships among all four variables. In examining the mediating effects of social‐support satisfaction, partial mediation for psychological sense of community on care‐giver satisfaction was determined, as well as full mediation for psychological sense of community on care‐giver stress. Therefore, firefighters who are satisfied with the support they receive may experience less stress with their care giving than those who experience low levels of support satisfaction. Future studies should assess these relationships more extensively in other areas of civic responsibility among public‐service employees to delineate effective support avenues. © 2004 Wiley Periodicals, Inc.
