Input: Consider Input: Abstract: From December 1981 through August 1984, 24 patients with spinal cord compression syndrome due to epidural neoplasms were evaluated for radiotherapy with clinical examination, radiographs of the spine, and myelography. All plain films were reviewed, and mock radiotherapy fields designed using specific criteria for margins. The same patients were reviewed a second time considering the additional information provided by myelography. The initial treatment fields were found to be inadequate in 69% of the patients. Even in patients with discrete bony lesions, the results of myelography affected the treatment 45% of the time. A history of previous spinal irradiation significantly influenced port design in only 1 of the 7 patients who had received previous radiotherapy. Although invasive, myelography is essential in planning the treatment of spinal cord compression.

Output: Impact of myelography on the radiotherapeutic management of malignant spinal cord compression.

Input: Consider Input: Abstract: Failure of the muscle to regenerate successfully is an important feature of the pathology of Duchenne muscular dystrophy (DMD). It is known that this is not due to a numerical reduction in the population of satellite cells. We have therefore examined the ultrastructural composition of the satellite cells in 25 DMD cases and compared them with satellite cells from normal subjects and from polymyositis patients to try to identify morphological features that might be associated with an impaired developmental competence. Profiles of randomly and serially sectioned satellite cells were analyzed stereologically to obtain nuclear and cytoplasmic areas. Within the cytoplasm, the areas occupied by mitochondria, rough endoplasmic reticulum (RER), and Golgi apparatus were measured. Micropinocytotic vesicles (MPVs) at the periphery of the cells were counted. The nucleus to cytoplasm ratios and mitochondrial, RER, and Golgi volume fractions were not significantly different in the three satellite cell samples. The cells in the DMD sample contained more MPVs than those in the normal subjects. This is attributed to a generalized cell response to a physiologically altered environment in the diseased muscle.

Output: A quantitative comparison of satellite cell ultrastructure in Duchenne muscular dystrophy, polymyositis, and normal controls.

Input: Consider Input: Abstract: A prospective study of six unselected couples diagnosed as having unexplained infertility was done. In three of six patients, subtle abnormalities in follicular development were detected. In the first case poor follicular growth was observed. There was a premature small rise of luteinizing hormone (LH) with subsequent low levels of estradiol (E2) in the late follicular phase and unusual wide LH peak. This was followed by low progesterone levels in the luteal phase. In the second case follicular growth was abrupted by premature LH surge. This surge was triggered by early rise of E2 level while the follicle was still small in size. In the third case luteinized unruptured follicle syndrome was diagnosed, on ultrasound examination. All of the abnormalities were repetitive.
Output: Subtle abnormalities in follicular development and hormonal profile in women with unexplained infertility.
