ABSTRACT
One of the standard treatments in laryngeal cancer is radiotherapy (RT). Many short- and long-term complications can occur in the region that has received radiotherapy. Definitive treatment of the emerging complications is still debatable, and treatment is challenging for radiation oncologists and ear nose throat specialists. Recently, hyperbaric oxygen treatment (HBOT) has become a promising alternative for the treatment of these complications. The aim of this report is to discuss the effectiveness of HBOT in the treatment of late-term RT-related potential complications in a patient with laryngeal cancer. We applied HBOT for a 58-year-old male patient with laryngeal cancer for the treatment of laryngeal oedema, and dyspnoea that developed one year after RT. In a decompression chamber at 2.4 atm pressure, the patient was made to breath 100% oxygen with a mask for 90 minutes. At the beginning, HBOT was planned for 30 days; however, it was terminated upon improvement of the symptoms at the 19th session. The symptoms, which developed one year after RT, were relieved completely with HBOT, and the patient is maintaining his life without any complaint under our control. The HBOT can be an alternative treatment for late-term complications developed after radiotherapy. It can be especially used for laryngeal oedema, and dyspnoea related to the field of radiotherapy.
ABSTRACT
INTRODUCTION: Wounds refractory to standard treatment in patients with thromboangiitis obliterans (TAO, Buerger's disease) are associated with amputation, other morbidity and mortality. The purpose of this study was to investigate the effect of hyperbaric oxygen treatment (HBOT) in patients with TAO. MATERIALS AND METHODS: Ninety-seven patients with TAO with ischaemic wounds treated between January 2007 and July 2016 were included in this dual-centre, non-randomised, retrospective study. Patients receiving HBOT in addition to conventional treatment were enrolled in an HBOT group (n = 47) and those receiving conventional treatment alone in a non-HBOT group (n = 50). All patients were Rutherford grade III at the time of enrolment. RESULTS: Significant improvement in the major amputation rate was observed in the HBOT group 10 months after starting treatment (2/47 vs. 13/50, P = 0.007). Numbers of patients progressing to Rutherford grade I (27/47 vs. 17/50, P = 0.035), numbers of patients healing completely (21 vs. 11, P = 0.031 and pain scores (visual analogue scale; 1, range 0-8 vs. 6, range 0-9, P < 0.001) were also significantly improved in the HBOT group. CONCLUSION: The addition of HBOT to conventional treatment in TAO patients with non-healing ischaemic wounds and severe extremity pain, conferred significant benefits in terms of wound healing and rest pain control. Multi-centre, prospective, randomized studies with blinded outcome analysis are now needed to elicit more reliable results.

Myoglobinuric acute renal failure (MARF) may develop after severe muscle injury. Heme oxygenase-1 (HO-1), a stress-response protein, has been implicated as a protective agent against MARF. We hypothesized that hyperbaric oxygen therapy (HBOT) may alleviate MARF by inducing renal HO-1 expression. Wistar-Albino rats were randomly assigned into three groups: Control (n = 4), MARF (n = 8), MARF + HBO (n = 8). MARF was induced by intramuscular glycerol (50%, 8 mL/kg) injection. Saline (8 mL/kg) was injected into the hind limb of the animals in the control group. Animals in the MARF + HBO group received two sessions of HBO therapy (90 min at 2.5 atm) 2 and 18 h after glycerol injection. Serum and tissue samples were taken at 24 h. Serum urea and creatinine levels increased in the MARF and MARF + HBO groups confirming the development of MARF. But, serum urea and creatinine levels were similar in MARF and MARF + HBO groups. Oxidative stress parameters were similar among all groups. Histological renal injury score was similar in MARF and MARF + HBO groups. HO-1 level, determined by immunohistochemistry, was significantly higher in MARF and MARF + HBO groups, compared to the control group. Although HO-1 level in MARF + HBO group was higher than MARF group, it was not statistically significant. We found that HBOT did not reduce renal injury in experimental MARF model. HBOT is used to reduce the muscle damage after crush injury, which may be accompanied by MARF. Therefore, more studies are needed to understand the effects of HBO treatment on renal functions after MARF.

Torsion of the testis is a urological emergency most commonly occurring in adolescent boys. Hyperbaric oxygen treatment (HBOT) has been shown to alleviate reperfusion injury in experimental ischaemia of the testis. We report a 13-year-old boy who had prolonged right testicular ischaemia. Despite surgery, the colour of the testis remained poor. He underwent a post-operative course of 10 HBOT over 8 days, with restoration of blood flow on colour Doppler and reduction of oedema. At four-month followup, the testis appeared normal on ultrasonography. To the best of our knowledge, this is the first published case of torsion of the testis treated with HBOT.
