The trigemino-cardiac reflex (TCR) is a well-known reflexive response in which bradycardia, hypotension, and gastric hypermotility are induced by stimulation of a peripheral or central portion of the trigeminal nerve. This reflex occurs during craniofacial surgery and other operations on or near the cerebellopontine angle, petrosal sinus, orbit and trigeminal ganglion. TCR is a well-known, although not well documented, phenomenon commonly observed during trans-sphenoidal surgery for resection of pituitary adenomas. We report a case in which asystole occurred during trans-sphenoidal surgery on a pituitary adenoma that was infiltrating the right cavernous sinus. When the anesthesiologist reported asystole, the team stopped manipulation and administered intravenous atropine. Intra-operative MRI showed a small tumour remnant in the right cavernous sinus. The operation was terminated but subsequent radiosurgery was planned for the residual tumor. Although TCR is rare and usually self-limiting, this case led us to change our treatment strategy. Surgeons who perform trans-sphenoidal surgery should be aware of this potential problem. Invasive pituitary adenomas should be removed gently and the risk of triggering TCR should be kept in mind. 相似文献

Thymic hyperplasia is a common phenomenon in both children and young adults after chemotherapy and may explain the finding of a mediastinal mass in patients with malignant lymphoma after complete remission. In the present study, we report 5 cases with malignant lymphoma presenting with a mediastinal mass on CT scan after completion of chemotherapy diagnosed as thymic hyperplasia by PET-CT imaging. We retrospectively analyzed 5 patients who presented with anterior mediastinal masses a median of 4 months (range 3–6) after achieving complete remission following successful treatment for malignant lymphoma. Three patients were diagnosed with Hodgkin’s lymphoma (HL) and the others with non-Hodgkin’s lymphoma (NHL). The median age of the patients was 23 (range of 18–47). PET-CT was performed on these patients to determine the characteristics of a mass which had been detected on CT. PET-CT was performed for all patients, and the thymic masses demonstrated only mild FDG uptake considered to be consistent with thymic hyperplasia. During a median of 24 months of follow-up, all patients were recurrence-free with a median survival of 15 months (range 10–26 months). It is important to be aware of the possibility of thymic hyperplasia after chemotherapy to avoid misdiagnosis or over-staging of disease, as well as unnecessary biopsies, especially when the presenting anterior mediastinal mass was originally located near the thymus on CT scan. Mild FDG PET uptake was sufficient for the diagnosis of benign disease in the cases in this study. 相似文献

Incisional hernias and abdominal-wall defects consume large amounts of healthcare resources. Use of mesh is effective in treatment
of these disorders and can decrease the rate of recurrence. This experimental study focused on the safety of mesh use in the
setting of malnutrition, a condition that impairs wound healing. Rats were divided into two groups: normally fed and food-restricted.
An abdominal-wall defect, 2 by 2 cm, was covered with polypropylene mesh, 2.5 by 2.5 cm. After sacrifice of the rats at the
21st and 60th days, tissue samples were sent for tensiometric and histopathological studies. No significant difference in
infectious complications was observed between the two groups. Tensiometry revealed no significant differences between the
groups. On histopathological examination, the only difference noted was in the vascularization scores of normally fed rats.
For malnourished subjects that survived after surgery, the use of polypropylene mesh appeared safe in the closure of abdominal-wall
defects, with no increase in infection rate and satisfactory wound healing. 相似文献

BACKGROUND: The aim of this study is to analyze the problems related to the ergonomic conditions faced by video endoscopic surgical teams during video endoscopic surgery by means of a questionnaire. METHODS: A questionnaire was distributed to 100 medical personnel, from 8 different disciplines, who performed video endoscopic surgeries. Participants were asked to answer 13 questions related to physical, perceptive, and cognitive problems. RESULTS: Eighty-two questionnaires were returned. Although there were differences among the disciplines, participants assessment of various problems ranged from 32% to 72% owing to poor ergonomic conditions. CONCLUSIONS: As the problems encountered by the staff during video endoscopic surgery and the poor ergonomic conditions of the operating room affect the productivity of the surgical team and the safety and efficiency of the surgery, redesigning of the instruments and the operating room is required. 相似文献

The spinal cord fills the length of the vertebral canal at the early period of intrauterine term. It is reported to extend to the level of the third lumbar vertebra at birth, because the vertebral column is growing more rapidly in the longitudinal direction than the spinal cord. The present investigation aimed to determine the changes in the termination level of conus medullaris (TLCM) from fetus to adulthood in a total of 285 individuals who had no defects in the central or peripheral nervous system, and were obtained from our Faculties of Medicine and Konya Maternity Hospital between 1992-1995. The age distribution was as follows: 36 fetuses, 20 prematures and 50 neonates, 51 children aged 1 to 7 years and 128 adults aged 15 to 68 years. In this study, for fetuses, prematures, neonates and children the TLCM was determined using ultrasonography. In addition, microdissection was used in fetuses to confirm the results obtained from the above technique. Also, magnetic resonance imaging was used in adults. During fetal life the end of the conus altered its levels from S5 to L3 vertebrae. The tip of the conus medullaris of the prematures and neonates ranged from L1 to L3 vertebrae. The tip of the conus medullaris in the children lay between the Th12 and L3 vertebrae, and in the adults it was between the Th12 and L2 vertebrae. There were slight differences between the prematures and neonates in terms of the TLCM. We concluded that there are differences in the TLCM between the age groups and therefore, especially in prematures and infants the determination of the tip of conus medullaris might be important for preventing postoperative neurological complications. 相似文献

A geographic information system was used in an epidemiological study of measles in Istanbul, Turkey. The aim was to obtain more reliable results and to increase the facilities for spatial monitoring in epidemiological studies. The Gaziosmanpasa district of Istanbul was selected as it experiences the highest level of migration, and currently has the highest population growth rate of the city's districts. The epidemic distribution of measles was investigated on the basis of examination of 320 children. The number, geographical distribution, complications and time of measles outbreaks were analysed and represented in thematic maps (a small selection is shown in this paper). The results were evaluated and, in view of these results, new vaccination plans were arranged. 相似文献
