PURPOSE: The characteristics of hypoparathyroidism in patients with Hashimoto thyroiditis (HT) after total thyroidectomy are not well established. The aim of this study was to investigate the relationship between hypoparathyroidism and loss of parathyroid glands in patients with or without HT who underwent total thyroidectomy. METHODS: Patients who underwent total thyroidectomy were divided into two groups; with HT (n=166) and without HT (n=526). Clinicopathologic characteristics were compared between the two groups. RESULTS: The mean numbers of parathyroid glands in specimens were significantly smaller in the with HT group than in the without HT group (0.34+/-0.51 vs. 0.42+/-0.58, P=0.003). The rate of transient hypoparathyroidism was significantly higher in the with HT group than in the without HT group (51.8% vs. 34.6%, P=0.000). Serum total calcium levels in patients who experienced transient hypoparathyroidism did not differ significantly between groups (P=0.335). The incidence of transient hypoparathyroidism of patients who preserved all four parathyroid glands or sacrificed one parathyroid gland was higher in the with HT group than in the without HT group, although that of patients who sacrificed two or more parathyroid glands was similar between groups. The incidence of permanent hypoparathyroidism in the two groups did not differ (P=0.546). CONCLUSION: Patients with HT had a higher rate of transient hypoparathyroidism after total thyroidectomy, particularly patients who preserved all four or three parathyroid glands. It is likely that the blood supply to the parathyroid gland might be vulnerable in patients with HT. Therefore, even though all parathyroid glands were preserved, careful monitoring of hypoparathyroidism is necessary after total thyroidectomy in patients with HT.

PURPOSE: Inhibitory effect of paclitaxel on neointimal hyperplasia after open cutdown has not been elucidated. METHODS: For the control group (n = 16), silicone 2.7-Fr catheters were placed via the right external jugular vein with the cutdown method. For the treatment group (n = 16), a mixture of 0.65 mg of paclitaxel and 1 mL of fibrin glue was infiltrated around the exposed vein after cutdown. After scheduled intervals (1, 2, 4, and 8 weeks), the vein segment was harvested and morphometric analysis was performed on cross-sections. RESULTS: Proliferation of smooth muscle cell (SMC) was strongly suppressed in the treatment group, and the ratio of neointima to vein wall was significantly reduced in the treatment group (8 weeks; 0.63 ± 0.08 vs. 0.2 ± 0.08, P < 0.05). Luminal patency was significantly more preserved in the treatment group, and the luminal area was significantly wider in the paclitaxel-treated group compared to the control group (8 weeks; 1.91 ± 0.43 mm² vs. 5.1 ± 0.43 mm², P < 0.05). Mean SMC counts measured at 1 and 2 weeks after cutdown were significantly lower in the treatment group (2 weeks; 115 ± 22 vs. 62 ± 22). Paclitaxel was undetectable in systemic circulation (<10 ng/mL). CONCLUSION: Sustained perivascular delivery of paclitaxel with fibrin glue was effective in inhibiting neointimal hyperplasia in rat jugular vein after open cutdown.

Background: : This study aims to report the development process of a communication training program targeting residents and nurses in a university hospital and discuss the results of the analysis of questionnaire responses received from the participants. Methods : A training program comprising a lecture on prescription principles, team communication, role-playing using cases based on medical errors related to prescriptions was developed. This two-hour program was conducted four times from September to December in 2022, with 31 residents and 37 nurses. After the program, the participants completed a questionnaire about program satisfaction. Results : An analysis of the questionnaire responses received from 28 residents and 37 nurses revealed that participants had an average satisfaction score ranging from 4.18 to 4.44 for each item. No difference was found between the residents’ and nurses’ responses. The participants shared positive opinions regarding the efficiency of the role-playing experience. The areas highlighted as those requiring improvement were the inclusion of various cases, improvement of teamwork, and a reduction in lecture volume. Conclusion : The participants reported being satisfied with the two-hour program to improve prescribing-related communication for residents and nurses. Future research should improve the program contents by reflecting on the opinions of the participants, and grasp the efficacy of the program by using a tool to measure communication skills or attitudes toward interprofessional collaboration before and after the program.

The mortality of patients with hemodynamic instability due to severe pelvic fracture is high despite multidisciplinary management. Current management algorithms for these patients emphasize pelvic angioembolization (AE) for hemorrhage control. However, a surgical procedure is often needed because AE is time-consuming and approximately only 15% of patients have arterial bleeding. Most hemorrhages from severe pelvic fracture originate from venous or bone injury. Current research demonstrates the effectiveness of preperitoneal pelvic packing (PPP) in hemorrhage control. However, there are no reports of its use in Korea. Accordingly, we present our early experiences of PPP for control of hemorrhage due to severe pelvic fracture in a trauma center in Korea.

Intradialytic blood pressure abnormalities are associated with adverse outcomes in patients with end-stage renal disease on dialysis. Vascular calcification is a common complicating feature, but whether this complication results in intradialytic blood pressure abnormalities remains uncertain. Therefore, this study investigated the relationship between coronary artery calcium score and intradialytic blood pressure abnormalities in patients with end-stage renal disease on maintenance hemodialysis. Thirty-six patients who received nongated chest computed tomography scans were included. Intradialytic hypotension was defined as a minimum intradialytic systolic blood pressure of <100 mmHg or a pre-dialysis blood pressure – minimum intradialytic systolic blood pressure >30 mmHg. Intradialytic hypertension was defined as >10 mmHg increase in systolic blood pressure (pre- to post-dialysis). Patients were classified as 22 (61.1%) with coronary artery calcium score <400 and 14 (38.9%) with coronary artery calcium score ≥400. Median systolic and diastolic blood pressures were equivalent, but median pulse pressure was higher in patients with coronary artery calcium score ≥400 than in those with scores <400. Coronary artery calcium score was comparable according to both intradialytic hypotension and hypertension, and had no correlation with systolic blood pressure fall and nadir systolic blood pressure. Coronary artery calcium score predicted the occurrence of cardiovascular events and all-cause mortality (hazard ratio 1.001 and 1.001; p=0.058 and 0.010). Coronary vascular calcification could be irrelevant to intradialytic blood pressure abnormalities in patients with end-stage renal disease on dialysis.
