The empty sella syndrome is characterized by obesity, frequent pregnancy, headache and high blood pressure, but its exact cause remains unknown. Usually the incomplete diaphragmatic sella has been considered as the cause of the empty sella syndrome, but some authors recently have suggested that the antipituitary antibody way be related to development of pituitary atrophy and the pituitary empty sella syndrome, and thus it may be clinically useful as screening test for the empty sella syndrome. We experienced two empty sella syndromes associated Graves disease and applied the antipituitary antibody as the diagnostic tool of the empty sella syndrome. But none of this two patients had antipituitary antibody and we report these cases with reviews of literatures.

Purpose: This qualitative study was to understand the awareness of epidemiological investigation tasks for nurses who were in charge of coronavirus disease 2019 (COVID-19) epidemiological investigations. Methods: Before data collection, written consent was obtained from 13 participants, and the data were then collected from September 1 to December 31, 2021. Individual interviews were conducted and recorded by video interview using Zoom, and data were transcribed verbatim. Four themes were derived by using the qualitative thematic analysis method. Results: The participants perceived that epidemiological investigations were burdensome but that the field work was important, and that expertise and collaboration were required. The participants started work without preparation due to the explosive increase in the number of confirmed COVID-19 cases, and they recognized work conflicts, unstable employment, and exhaustion as obstacles to their work performance. On the other hand, the participants took pride in contributing to the national epidemiological investigation and control and felt a sense of responsibility as nursing professionals. Finally, participants mentioned that the training of infectious disease practitioner was important for work improvement. Conclusion Further research is needed on the development of standardized manuals for the training of nursing personnel as infectious disease specialists through the job analysis of epidemiological investigators.

Although lymphoma may involve any part of gastrointestinal tract either primary or secondary, esophageal involvement is rare. Secondary esopahgeal involvement of lymphoma is showing an incidence between 0% and 6% with autopsy series and lesser then 1% in living patients. The occurrence of a tracheoesophageal fistula(TEF) in patient with lymphoma is even more rare. We describe one case of TEF due to secondary esophageal invasion of T-cell lympboma and review the literature, with particular attention to chest CT and esophagoscopic finding, and endoscopic biopsy result.

Blueberry muffin rashes occur in various diseases including TORCH syndrome, transfusion reactions, leukemia, hereditary spherocytosis and neonatal sepsis. We report a case of congenital CMV(cytomegalovirus) infection showing blueberry muffin skin lesions which revealed dermal erythropoiesis. Even though these cutaneous findings were nonspecific, they could provide a valuable clue in approach the congenital viral infection in the perinatal period.

Hemiballism describes involuntary severe, violent, arrhythmic, rotatory and large amplitude movements of limb from proximal joint. We experienced an elderly stroke patient with hemiballism accompanied dysphagia that persisted for several months severity was evaluated by the Universidade Federal de Minas Gerais Sydenham's chorea rating scale (USCRS) and video fluoroscopic swallowing study (VFSS). In this case, we observed the improvement of hemiballism by conventional rehabilitation therapy and low dose quetiapine. Therefore, we recommend geriatrists considers vthese therapies in elderly patients with hemiballism.

PURPOSE: The primary objective of this study was to examine the changes of basal cortisol and DHEA levels present in saliva and serum with age, and to determine the correlation coefficients of steroid concentrations between saliva and serum. The secondary objective was to obtain a standard diurnal rhythm of salivary cortisol and DHEA in the Korean population. MATERIALS AND METHODS: For the first objective, saliva and blood samples were collected between 10 and 11 AM from 359 volunteers ranging from 21 to 69 years old (167 men and 192 women). For the second objective, four saliva samples (post-awakening, 11AM, 4PM, and bedtime) were collected throughout a day from 78 volunteers (42 women and 36 men) ranging from 20 to 40 years old. Cortisol and DHEA levels were measured using a radioimmunoassay (RIA). RESULTS: The morning cortisol and DHEA levels, and the age-related steroid decline patterns were similar in both genders. Serum cortisol levels significantly decreased around forty years of age (p < 0.001, when compared with people in their 20s), and linear regression analysis with age showed a significant declining pattern (slope= -2.29, t= -4.297, p < 0.001). However, salivary cortisol levels did not change significantly with age, but showed a tendency towards decline (slope= -0.0078, t= -0.389, p=0.697). The relative cortisol ratio of serum to saliva was 3.4 - 4.5% and the ratio increased with age (slope=0.051, t=3.61, p < 0.001). DHEA levels also declined with age in saliva (slope= -0.007, t= -3.76, p < 0.001) and serum (slope= -0.197 t= -4.88, p < 0.001). In particular, DHEA levels in saliva and serum did not start to significantly decrease until ages in the 40s, but then decreased significantly further at ages in the 50s (p < 0.001, when compared with the 40s age group) and 60s (p < 0.001, when compared with the 50 age group). The relative DHEA ratio of serum to saliva was similar throughout the ages examined (slop = 0.0016, t = 0.344, p = 0.73). On the other hand, cortisol and DHEA levels in saliva reflected well those in serum (r = 0.59 and 0.86, respectively, p < 0.001). The highest salivary cortisol levels appeared just after awakening (about two fold higher than the 11 AM level), decreased throughout the day, and reached the lowest levels at bedtime (p < 0.001, when compared with PM cortisol levels). The highest salivary DHEA levels also appeared after awakening (about 1.5 fold higher than the 11 AM level) and decreased by 11AM (p < 0.001). DHEA levels did not decrease further until bedtime (p=0.11, when compared with PM DHEA levels). CONCLUSION: This study showed that cortisol and DHEA levels change with age and that the negative slope of DHEA was steeper than that of cortisol in saliva and serum. As the cortisol and DHEA levels in saliva reflected those in serum, the measurement of steroid levels in saliva provide a useful and practical tool to evaluate adrenal functions, which are essential for clinical diagnosis.

Proangiogenic cells (PACs) display surface markers and secrete angiogenic factors similar to those used by myelomonocytic cells, but, unlike myelomonocytic cells, PACs enhance neovascularization activity in experimental ischemic diseases. This study was performed to reveal the differential neovascularization activities of PACs compared with those of myelomonocytic cells. We cultured PACs and CD14+-derived macrophages (Macs) for 7 days. Most of the surface markers and cytokines in the two cell types were alike; the exceptions were KDR, beta8 integrin, interleukin-8 and monocyte chemotactic protein-1. Unlike Macs, PACs significantly enhanced mesenchymal stem cell (MSC) transmigration. PACs and Macs increased neovascularization activity in an in vitro co-culture of human umbilical vein endothelial cells and MSCs and in an in vivo cotransplantation in Matrigel. However, the use of Macs resulted in inappropriately dilated and leaky vessels, whereas the use of PACs did not. We induced critical hindlimb ischemia in nude mice, and then transplanted PACs, Macs or vehicle into the mice. We obtained laser Doppler perfusion images weekly. At 2 weeks, mice treated with PACs showed significantly enhanced perfusion recovery in contrast to those treated with Macs. After day 7, when cells were depleted using a suicidal gene, viral thymidine kinase, to induce apoptosis of the cells in vivo by ganciclovir administration, we found that the improved perfusion was significantly abrogated in the PAC-treated group, whereas perfusion was not changed in the Mac-treated group. PACs caused an increase in healthy new vessels in in vitro and in vivo models of angiogenesis and enhanced long-term functional neovascularization activity in the hindlimb ischemia model, whereas Macs did not. Nevertheless, the angiogenic potential and long-term functional results for a specific cell type should be validated to confirm effectiveness and safety of the cell type for use in therapeutic angiogenesis procedures.

Objective: To evaluate the baseline colon transit time and rectoanal manometry and the effects of the electrical stimulation to the sacral dermatomes for the neurogenic bowel according to the level of spinal cord injury. METHOD: To determine the baseline differences, thirty three patients were classified into two groups: cord injured level above T9 and from T9 to L2. And thirteen patients were included in follow-up study to evaluate the effects of 4 weeks electrical stimulation. RESULTS: There was no significant difference in the baseline colon transit time on two groups. After electrical stimulation, the left and rectosigmoid transit time was more improved in lower level injured group comparing with upper level injured group. In the rectoanal manometry the mean resting anal pressure, mean squeezing pressure, high pressure zone, and threshold of rectoanal inhibitory reflex were increased after the electrical stimulation on two groups. And the mean squeezing pressure on T9-L2 injured patients was significantly increased (p<0.05). CONCLUSION: The elecrical stimulation to the sacral dermatomes increased the mean squeezing pressure of rectoanal manometry more significantly on the T9-L2 injured patients than the group of spinal cord injured level above T9. However, there was no statistically significant difference in the colon transit time before and after the electrical stimulation between two groups
