Clinical Experience of Use of Kampo Medicine Shakuyakukanzoto for Muscle Spasms Caused by Tetanus.

Background Tetanus is an infectious disease caused by Clostridium tetani, which produces tetanospasmin. Intensive care using sedatives and muscle relaxants is required for the management of severe tetanus, however, long-term use of those medicines is associated with the occurrence of post-intensive care syndrome (PICS). Shakuyakukanzoto (SKT), which is clinically used for the treatment of pain associated with sudden myospasm widely, is one of Kampo medicines, and some studies showed that they are effective in treating muscle spasms caused by tetanus. The purpose of this study is to evaluate the usefulness of SKT in the management of tetanus patients from the viewpoint of the reduction of sedatives. Methods Patients who were diagnosed with tetanus and were treated in our hospital between January 2006 and December 2022 were included. Patients were divided into two groups, patients treated with SKT and those without SKT, and the background information and clinical courses, especially the reduction of sedatives, were compared between the two groups. Results There were five tetanus patients who were treated with SKT (SKT(+) group) and two tetanus patients without SKT (SKT(-) group), respectively. Intubation and mechanical ventilation were required for the management of generalized seizures in all seven patients, who were admitted to the intensive care unit (ICU). The administration of propofol could be discontinued after an average of 8.6 days (range: 3-22 days) from the initiation of SKT administration. The dosage of propofol was lower in patients who received SKT versus those who did not; midazolam and fentanyl exhibited a similar tendency. The mean durations of ICU and hospital stays for patients treated with or without SKT were almost equal (the mean durations of ICU stay in SKT(+) and SKT(-) groups were 22.6 and 24.0 days, and those of hospital stay in SKT(+) and SKT(-) groups were 35.2 and 36.0 days, respectively). All seven patients were discharged and transferred to another hospital for rehabilitation. Conclusions SKT may be useful in the management of myospasms in patients with tetanus. It may also prevent the occurrence of PICU in patients with tetanus who require intensive care by reducing the use of sedatives and analgesics.

Cystoperitoneal shunt for a giant intrathoracic meningocele under local anesthesia.

Giant intrathoracic meningoceles are extremely rare, and the standard treatment for giant intrathoracic meningoceles remains controversial. We present the case of a patient with giant intrathoracic meningoceles associated with neurofibromatosis type I. Our patient had poor respiratory function because of the giant intrathoracic meningocele, so we performed a cystoperitoneal shunt under local anesthesia. We describe our cystoperitoneal shunt technique using an adjustable-pressure valve. This simple, minimally invasive treatment is a valuable alternative treatment option in patients at high operative risk, especially those with low respiratory function.

Long-term preservation using a new apparatus combined with suppression of pro-inflammatory cytokines improves donor heart function after transplantation in a canine model.

OBJECTIVE: We developed a new apparatus for long-term heart preservation that combines simple immersion with coronary perfusion. In a previous study, we reported that suppression of pro-inflammatory cytokines, such as tumor necrosis factor alpha (TNF-alpha) and interleukin-1beta (IL-1beta), improved results after transplantation. In this study, we evaluated whether long-term preservation using our apparatus for continuous coronary perfusion, combined with suppression of pro-inflammatory cytokines, improves donor heart function after transplantation in a canine model. METHODS: We used adult mongrel dogs in this study. Coronary vascular beds were washed with University of Wisconsin (UW) solution after arresting hearts with glucose-insulin-potassium solution. The heart was then excised and preserved for 12 hours with a combination of immersion and coronary perfusion using a preservation apparatus. Adult mongrel dogs were divided into 2 groups: the coronary perfusion (CP) group (n = 7) and the FR167653 (FR-CP) group (n = 6). In the CP group, we used a 4 degrees C UW solution for immersion and coronary perfusion. In the FR-CP group, we used a 4 degrees C UW solution supplemented with 20 mg/liter of the anti-inflammatory agent FR167653 for immersion and coronary perfusion. At 2 and at 3 hours after orthotopic transplantation, we compared hemodynamic parameters with pre-operative values in donor animals, with right atrial pressure at 10 mm Hg and with 5 microg/kg/min dopamine infusion. We compared serum concentrations of TNF-alpha from the coronary sinus and compared electron microscopic studies between the 2 groups. RESULTS: Three hours after transplantation, cardiac output (CO), left ventricular pressure (LVP), and -LVdp/dt were significantly greater (p < 0.05) in the FR-CP group than in the CP group (CO, 178% +/- 65% vs 93% +/- 40%; LVP, 115% +/- 22% vs 73% +/-26%; -LVdp/dt, 168% +/- 13% vs 61% +/- 17%, respectively). Electron microscopic studies showed that glycogen was well preserved in the FR-CP group compared with the CP group. Serum concentrations of TNF-alpha were decreased significantly in the FR-CP group compared with the CP group at 3 hours after reperfusion (161 +/- 54 pg/dl vs 642 +/- 636 pg/dl, respectively). CONCLUSION: Hemodynamics after transplantation were significantly better in the FR-CP group than in the CP group. The combined preservation method of continuous perfusion and immersion using our apparatus in conjunction with suppression of pro-inflammatory cytokines improves donor heart function after transplantation.
