Immunohistochemical Expression of Synaptophysin in the Adult and Developing Cervical and Lumbar Enlargements of the Spinal Cord of Rabbit

Background: The principle findings of synaptophysin immunoreactivity (SynpIR) during the ontogeny of rabbit spinal cord are: At E14, SynpIR precedes in the entire marginal layer especially at the entrance zone of dorsal root and motor neurite outgrowth emerged from the basal plate. At E21, SynpIR is expressed in the motoneurons of ventral and lateral horns of mantle layer growing into the ventrolateral columns of marginal layer. Methods: We found intensely stained thick tracts and diffuse axons among proliferating neuroblasts of mantle layer. The peripheral parts of ventral horns were occupied with closely packed multipolar neurons from which long dendrites departed toward the surface of marginal layer. Results: At E28, pronounced SynpIR presented in the ventral grey horn while the white matter was faintly stained., meanwhile the dorsal horn was more cellular than ventral and lateral horns. Few intensively SynpIR fibers cross the dorsal and ventral commissures. In adult, profuse SynpIR appeared in the entire grey matter, and stained dendrites departed from neurons in the lateral laminae into the adjacent funiculi as finger-like projections. These projections did not reach the surface, so that the outer one-third to onefourth of the funiculi contained little or no SynpIR. In the periphery of ventral horns, we found large multipolar neurons with faintly stained cytoplasm. The white matter and the neuroepithelial cells surrounding the central canal were almost unstained. Conclusion: Synaptophysinis a reliable marker for fiber outgrowth and synapse formation in therabbit spinal cord, and its differential expression levels is specific and almost completed before birth.

Etiology of pleural effusion among adults in the State of Qatar: a 1-year hospital-based study

There have been no systematic studies of diseases causing pleural effusion in Qatar. This prospective, hospital-based study involved all adult patients [> 15 years] with pleural effusions who were admitted to referral hospitals over a 1-year period. A total of 200 cases of pleural effusion were identified [152 males and 48 females]; mean age 45.1 [SD 18.5] years. A majority of patients [73.5%] were non-Qataris, mostly from the Asian subcontinent. The most frequent cause of pleural effusions was tuberculosis [32.5%], followed by pneumonia [19%], cancer [15.5%] and cardiac failure [13%]. The most frequent cause of malignant effusion was bronchogenic carcinoma [38.7%], whereas Gram-positive organisms were the most frequent isolates from empyema fluid [62.5%]. Histological examination and culture of pleural biopsy were the most useful diagnostic workup for tuberculosis effusions, whereas repeated cytological examination of pleural fluid and pleural biopsy were most useful for malignant effusions

Eosinophilic pleural effusion due to cloxacillin and piperacillin/tazobactum

A young male was treated for right-sided pneumonia with cloxacillin and piperacillin/tazobactam. As he was recovering from the pneumonia he developed left-sided pleuritic pain and pleural effusion. At thoracocentesis an exudative pleural effusion contained 16 percent eosinophils with a simultaneous 28 percent peripheral eosinophilia. An allergic reaction to penicllins was thought to be the cause. After withdrawal of those medications and institution of prednisolone a rapid resolution was seen of symptoms, signs, peripheral eosinophilia and radiological abnormalities

Impact of ostomy on the quality of life of Egyptian cancer patient

The present study aimed at investigate the concept of QOL among Egyptian ostomates, as well as assess nursing intervention that may affect this concept. The study sample consisted of 50 ostomate patients with a different type of diversions. They drawn from Outpatients Clinic of the National Cancer Institute, Cairo University. Four instruments were used for data collection: Demographic data sheet, questionnaire sheet to assess type of information, an open ended six questions covering the concept of QOL and a modified QOL model for colostomy patient. Results of the study revealed that high percentage of patients perceived QOL as "being healthy" and productive. The highest mean score was fear of odor also a significant differences were put into evidence between adjustment to stoma and other variables of QOL index. The study recommended that psychosocial needs of ostomates should be provided upon, also visiting services by a qualified member should be provided
