RESUMEN
Objectives: Clostridioides difficile (CD) is an anaerobic spore-forming Gram-positive rod that is a major cause of antibiotic-associated diarrhea. Hyperbaric oxygen therapy (HBO) is a well-established treatment for Clostridium perfringens, but there are no reports that have examined the efficacy of HBO against CD, which is also an anaerobic bacterium. Methods: In this study, we retrospectively examined whether HBO therapy affects the prognosis following CD infections (CDI). This study included 92 inpatients diagnosed with CDI at our hospital between January 2013 and December 2022. Of these, 16 patients received HBO therapy. The indications for HBO therapy were stroke in five patients, ileus in four patients, cancer in two patients, acute peripheral circulatory disturbance in two patients, and others in three patients. The mean observation period was 5.4 years. Results: In the univariate analysis, there was no significant difference in severity, mortality, hospitalization, or overall survival between patients who did and did not receive HBO therapy. However, the HBO group had a significantly lower recurrence rate (0% vs. 22.4%, p=0.0363) and a shorter symptomatic period (6.2 vs. 13.6 days, p=0.0217). Conclusions: HBO may have beneficial effect on CDI by shortening the symptomatic period and preventing recurrence.
RESUMEN
The most suitable management of recurrent abdominal desmoid tumor is still unclear. A case of recurrent huge abdominal desmoid tumor successfully treated by hyperthermia therapy is described. A 63-year-old man was operated upon for desmoid tumor in the retroperitoneum involving pancreas, posterior wall of the stomach and transverse mesocolon in 2007. In 2008, the tumor recurred and could not be resected because of the patient refused the operation. Several therapies using tamoxifen, anastrozole, imatinib mesylate and radiotherapy were all ineffective. The tumor grew bigger and bigger during a treatment period. Finally, hyperthermia treatment was applied to the tumor. The size of the recurrent desmoid tumor reduced 75% by hyperthermia treatment for 46-month. Base on this experience, we recommend hyperthermia as the treatment for patients with recurrent abdominal desmoid tumor that several therapeutic strategies did not achieve a remarkable response.
