RESUMO
Foot-and-mouth disease (FMD) is a highly contagious and economically important viral disease of cloven-hoofed animals. Routine vaccination is one of the preferred methods of protection against this disease in endemic countries. For protective immunity against FMD, repeated immunizations with frequent administration are required. Intradermal immunization has many advantages over intramuscular administration of vaccines. In this study, a commercial tetravalent FMD vaccine adjuvanted with Montanide ISA 206 was administered to cattle via the intramuscular (2 mL [n = 10] and 0.5 mL [n = 9]) and intradermal (0.5 mL [n = 11]) routes. Booster doses were administered 28 days later using the same vaccine and routes. Serum samples were collected on days 0, 7, 14, and 28 post-vaccination (pv) and at 30 and 60 days post-booster. Homologous and heterologous virus neutralization tests and liquid-phase blocking and isotype ELISAs were used to measure the antibody response. The results showed that intradermal administration of quarter doses of the vaccine provides an equal or better virus neutralization antibody response than intramuscular administration of the same dose of vaccine after booster administration in cattle. This means that four times more cattle can be immunized with the same amount of vaccine using the intradermal route without compromising immunity.

OBJECTIVES: Carbon monoxide (CO) poisoning remains the foremost cause of poisoning worldwide. This study aimed to investigate the effects of hyperbaric oxygen therapy (HBOT) and normobaric oxygen therapy (NBOT) on thiol/disulfide homeostasis in children with CO intoxication. METHODS: Eighty-one children aged 0 to 18 years with CO intoxication were included in this cross-sectional study. No changes were made in the routine clinical evaluation and treatment practices of the patients. Thirty-two children who received HBOT and 49 children who received NBOT were compared for serum native thiol, disulfide, and total thiol levels, as well as for the changes in disulfide/native thiol, disulfide/total thiol, and native thiol/total thiol ratios before and after treatment. RESULTS: Antioxidant levels, such as native thiol and total thiol, were significantly decreased in patients who received HBOT and increased in those who received NBOT (P = 0.02 and P = 0.01, respectively). There was no statistically significant difference between the 2 groups concerning the change of native thiol/total thiol ratios (P = 0.07). In addition, there was no significant difference regarding changes in disulfide, disulfide/native thiol, and disulfide/total thiol levels before and after treatment (P = 0.39, P = 0.07, and P = 0.07, respectively). CONCLUSIONS: Although thiol-disulfide balance is maintained in patients treated with HBOT, antioxidant levels decrease significantly compared with NBOT. Despite efficiency of HBOT in CO intoxication, oxidative stress and reperfusion injury due to hyperoxygenation should be considered in the treatment of HBOT.

Overactive bladder (OAB) is a disease with symptoms such as feelings of urgency, nocturia, and frequent urination which is usually accompanied by urinary incontinence. We aimed to assess the effect of hyperbaric oxygen (HBO2) therapy on the symptoms of female patients with overactive bladder (OAB). This study is a prospective observational cohort study. The patients were analyzed into two groups. The patients who received HBO2 therapy were in Group 1, and the patients who received mirabegron treatment were in Group 2. The symptom scores and quality of life scores of the patients before and after treatment were recorded and compared. Significant improvement in symptom scores were seen in both groups after treatment compared to baseline. The study included 31 patients in Group 1 and 44 patients in Group 2. The mean changes in the ICIQ-SF, OAB-V8, and IIQ-7 scores in the third month of treatment in Group 1 were 4.12 ± 3.51, -10.70 ± 6.92, and -4.51 ± 2.68, respectively. The corresponding mean score changes in Group 2 were -4.31 ± 3.16, -11.22 ± 5.93, and -3.68 ± 2.67, respectively. The mean changes in all three scores were not significantly different between Groups 1 and 2 (p = 0.81, 0.73, and 0.19, respectively). We observed that HBO2 treatment improved quality of life by reducing the symptom score in patients with OAB. Moreover, this effect continued in the third month after the treatment. Considering the efficacy and side effect profiles of the available treatments, HBO2 therapy may be a new treatment alternative in OAB.

OBJECTIVE: Closer monitoring and treatment is vital for pregnant carbon monoxide (CO) poisoning cases due to fetal poisoning component. Permanent damage can occur in both the mother and the baby. It may cause stillbirth even though no serious clinical symptoms occur in the mother. Hyperbaric oxygen (HBO) treatment is advised for all pregnant patients regardless of their clinical symptoms. Pregnant CO poisoning patients that received HBO treatment and their fetal status were evaluated in this study. METHODS: Pregnant patients poisoned with CO treated in the same hyperbaric clinic were evaluated. Pregnant patients that received HBO treatment in a multiplace chamber were evaluated in terms of clinical status, demographic structure, laboratory tests, fetal effects and progress of the fetus until birth and 6 months postpartum. RESULTS: A total number of 32 pregnant cases were treated. COHb values were over 20% (min 6.9- max 40.2) in 23 patients, 11 patients had a history of syncope. All patients took HBO treatment under 2.4 ATA pressure for 120 min. 3 patients received more than 1 session of HBO treatments due to fetal stress; all other cases took 1 session of HBO treatment. No spontaneous abortus occurred in early follow-ups; only 4 babies were born prematurely. 2 of the babies were lost in the early phases after birth, due to causes non-related to CO poisoning complications (cyanotic heart disease, necrotising enterocolitis). No significant difference were observed in the comparison of laboratory results of patients with syncope and of those who did not have syncope and comparison of patients with COHb value higher than 20% and patients with COHb value lower than 20% (p > 0.05). CONCLUSION: HBO is not advisable for pregnant patients except for CO poisoning. In this study it is observed that HBO treatment under 2.4 ATA pressure for 120 min has no harmful effects on the mother and the fetus. It is observed that continuation of HBO treatment in the cases with fetal distress findings has beneficial effects. COHb levels and syncope were shown to have no significant effect on clinical symptoms and on blood tests.

Hypertrophic scar is a disease with complicated treatment methods. Although there are numerous studies in the literature definitive therapy has not been reported yet. In this study, we aimed to evaluate the short and long-term effects of HBOT on hypertrophic scar formation in a rabbit ear model. A total of 20 male New Zealand rabbits weighing 2.1 to 2.4 kg were used in this study. The rabbits in group 2 were exposed to hyperbaric oxygen treatment for 7 days starting from the first day following biopsy punch, while no extra treatment was applied to the rabbits in group 1. Macroscopic scar thickness, histopathological parameters and HI were assessed in both of the 30th day and 60th day scars. Scar thickness was found significantly less in the scars of the rabbits exposed to HBOT (P < .05). And less dermal hypertrophy was also found in HI results of group 2.(P ≈ .022) There were differences between groups in terms of inflammation, vascularization and density of collagen fibrils. HBOT applied for 7 days from the first day of wound formation has both short and long-term effects on the triggering factors of hypertrophic scar, especially on inflammation.

The Eurasian Tunnel is a 5.64-km crossroad tunnel that connects Europe and Asia. Located under the seabed for the first time, 3.34 km of the tunnel that crosses the Bosphorus was built by advanced tunneling techniques. An exclusively designed tunnel boring machine (TBM), which has an operating pressure of 11 bars and a diameter of 13.7 meters was used for boring the seabed tunnel. The deepest point was 106 meters below sea level. One bounce diving period and seven saturation diving periods were needed for the repair and maintenance of the TBM during the project. Total time spent under pressure was 5,763 hours. A saturation decompression chamber for four divers was used for the saturation interventions, and divers breathed trimix at storage and excursion depths. The longest saturation run was the second, with storage at 10 bars and excursions to 10.4 bars. Twenty-three professional divers who were all experienced in compressed-air work were assigned to work on the project. Four dive physicians provided medical support, which included screening of divers before and during the hyperbaric interventions as well as on-site supervision. There were no diving-related accidents. A minor hand trauma, an external otitis and occasional insomnia were non-diving-related health issues that occurred during saturation and bounce diving. To our knowledge, the Eurasian Tunnel was the first project to perform TBM repair operations at such depths under the seabed and the first saturation diving in Turkey. In this report, we aimed to share our experiences of hyperbaric medical consulting in support of this type of tunneling project.

BACKGROUND: The aim of the study was to determine the effect of different application timings of hyperbaric oxygen treatment (HBO) on nerve regeneration in rats. MATERIALS AND METHODS: A total of forty 12-week-old female Wistar albino rats were used. The sciatic nerve was transected. The nerve ends were then realigned and repaired using standard microsurgical techniques. Animals were randomly assigned to four groups: 1) No hyperbaric oxygen, sectioned and repaired; 2) HBO started at postoperative first hour, sectioned and repaired; 3) HBO started at postoperative first week, sectioned, and repaired; and 4) HBO started at postoperative second week, sectioned, and repaired. All rats in all groups were evaluated with gait analysis at 8 and 16 weeks postoperatively. Sciatic function index was calculated. Sciatic nerve samples were taken after gait analysis at 16th week. Foreign body reaction, the intensity of the inflammatory cells and types, repair-associated vascular proliferation in the field, axonal vacuolar degeneration of the fibers from the cut line transition density and switching layout, and myelinization density with perineural sheath were evaluated histopathologically. RESULTS: At the 16th week, group 2 demonstrated the best gait analysis results. Gait analysis was better for group 3 than groups 1 and 4 (P < 0.05). No significant differences were observed among the groups in inflammation (P > 0.05). Fibrosis was statistically less in group 2 than that in other groups (P < 0.05); however, no significant differences were observed among groups 1, 3, and 4 (P > 0.05). CONCLUSIONS: Our results suggest that initiating HBO early after nerve repair will make a positive impact on recovery. © 2016 Wiley Periodicals, Inc. Microsurgery 36:586-592, 2016.

BACKGROUND AND OBJECTIVE: Hand ulcers are seen in a small percentage of patients with diabetes. The predisposing factors of diabetic hand varies between different countries. However, the effects of predisposing factors on prognosis are not clear in diabetic hand infections. In this study, our aim was to determine the effects of predisposing factors on poor prognostic outcomes in patients with diabetes mellitus. METHODS: Thirty-four patients with diabetes mellitus who were treated and followed up for a hand infection in between 2008 and 2014 were investigated retrospectively. Patients were evaluated according to predisposing factors defined in the literature that included disease period, age, gender, admission time, presence of neuropathy, smoking habits, HbA1c levels at admission time, peripheral vascular disease, end-stage renal disease (ESRD), and trauma. Death and minor/major amputation cases during treatment were defined as poor prognosis. RESULTS: Patients who had ESRD, peripheral neuropathy, or an HbA1c level greater than 10% had significantly higher amputation rates. CONCLUSIONS: Peripheral neuropathy, ESRD, and HbA1c levels greater than 10% at the time of admission were determined as poor prognosis criteria for diabetic hand treatment.
RESUMO
We aimed to evaluate nasal mucosal changes and efficiency of nasal steroids and diclofenac on nasal mucosa during hyperbaric oxygen (HBO) treatment. Forty adult Albino-Wistar rats were randomized into four groups. Group 1 (control group) (n = 10) not exposed to hyperbaric or enhanced oxygen concentrations; group 2 (HBO group) (n = 10) underwent only HBO treatment; group 3 (n = 10) received HBO and intranasal mometasone furoate (10 µl/day); group 4 (n = 10) treated with HBO and diclofenac sodium (10 mg/kg/day ip). Specimens of nasal mucosa were collected after sacrificing and dissection of animals. The specimens were processed for light microscopic evaluation, and then evaluated histopathologically for fibroblastic proliferation and inflammation. Regarding the scores of inflammation, the level of inflammation in the control group was significantly less severe than the other groups (p < 0.05). Evaluation of the fibrosis scores showed that the scores of both groups 2 and 4 were significantly increased (p < 0.05). There were no statistically significant differences between groups 2, 3, and 4 as for fibrosis and inflammation (p > 0.05). Chronic HBO treatment induced mild inflammation of the nasal mucosa. These effects cannot be prevented adequately by administration of nasal steroids and diclofenac.

BACKGROUND: Necessity of new and alternative treatments in traumatic facial nerve injury. AIMS/OBJECTIVE: In this experimental study, we aimed to evaluate the histopathologic and functional effects of methylprednisolone, hyperbaric oxygen and hesperidin + diosmin treatments on traumatic facial nerve regeneration in rats. METHODS: After facial nerve injury, five groups were formed with eight rats in each group: Group 1 (negative control), 2 (operation), 3 (corticosteroid), 4 (hyperbaric oxygen), 5 (hesperidin + diosmin). Blink reflex of rats evaluated a day after the operation and at the first, second and third weeks. Facial nerve samples from sacrificed animals were examined under a light microscope. RESULTS: According to our results, in group 4; axonal degeneration and vascular congestion were significantly lower than group 2 and 3, and myelin sheath thickness was significantly higher than group 3. In group 5; axonal degeneration was significantly lower than group 2 and vascular congestion was significantly lower than group 2 and 3. In terms of functional recovery; there was no statistically significant difference between the groups. CONCLUSIONS AND SIGNIFICANCE: It has been shown that both hyperbaric oxygen and hesperidin + diosmin treatments have positive effects on facial nerve regeneration. Both treatments may be good alternatives for ameliorating traumatic nerve injury, but these treatment modalities need to be further explored.

Foot and mouth disease (FMD) and Lumpy skin disease (LSD) are contagious viral diseases that cause significant economic damage in the livestock industry of countries. Cattle are vaccinated two times a year with FMD and sheep pox and goat pox vaccines (SGP) within 30-day intervals to combat both diseases in Türkiye. However, vaccinations in different periods increase vaccination costs, labor, and distress on animals. Therefore, it was aimed to determine the effects of simultaneous vaccination of FMD and SGP vaccines on the immunity against LSD and FMD in cattle. For this purpose, animals were divided into 4 groups; SGP vaccinated group (Group 1, n = 10), FMD vaccinated group (Group 2, n = 10), FMD and SGP simultaneously vaccinated group (Group 3, n = 10), and the unvaccinated control group (Group 4, n = 6). Blood samples were collected and analyzed to detect the antibody response against the LSD via Capripoxvirus (CaPV) ELISA and FMD by Virus Neutralisation test (VNT) and Liquid Phase Blocking ELISA (LPBE). A live virus challenge study was performed to determine the immune response against LSD. The mean antibody titers were determined protective levels on 28 days post vaccination (DPV) against FMDV serotypes O and A, respectively. The logarithmic difference of skin lesions was calculated log10 titer > 2.5. LSD genome could not be detected in the blood, eyes, and nose swap samples of the challenged animals on the 15th day via PCR. In conclusion, adequate protective immune response was provided against LSD when the SGP and FMD vaccines were used simultaneously in cattle.

BACKGROUND: In this study, we investigated the effect of hyperbaric oxygen therapy (HBOT) on the morphology of estradiol valerate (EV) induced polycystic ovary (PCO) to find a new treatment modality for improvement of PCO. METHODS: The rats were divided into four groups. Group1, control; group 2, PCO group; group 3, PCO with HBOT group and group 4, normal ovary with HBOT. PCO was induced by a single intramuscular injection of 4 mg EV in adult cycling rats. Other rats with normal ovaries had oil injection as placebo. HBOT was applied to third and fourth groups for six weeks. Histopathologic evaluation of ovaries of all groups were performed & compared. RESULTS: Six weeks of HBOT was resulted in increase in follicular atresia, decrease in the number of primary, secondary, tertiary follicles and decrease in the number of fresh corpus luteum in normal rat ovary. HBOT on polycystic rat ovary, resulted in significant increase in atretic follicles which were already present. CONCLUSIONS: HBOT of six weeks itself, changed ovarian morphology in favor of atresia both in PCO group and control group. This result of aggravated follicular atresia after HBOT on EV induced PCO may be due to long-term exposure in our protocol which with this state seems to be inapplicable in the improvement of PCO morphology.

PURPOSE: Several experimental studies have investigated the effects of hyperbaric oxygen therapy (HBOT) on peripheral nerve regeneration. However, to the best of our knowledge, clinical studies to evaluate the effects of HBOT on peripheral nerve recovery are seldom performed. The aim of our study was to investigate the efficacy of HBOT following primary nerve repair in patients with upper extremity nerve injuries. METHODS: Patients admitted to our hospital between 2015 and 2019 with ulnar and median nerve injuries were included in the study. Patients were randomized based on their application dates and divided into two different groups. Patients who received HBOT following standard epineural nerve repair were included in group 1, while patients who only underwent epineural nerve repair were included in group 2. All patients were followed up at 3, 6, and 12 months post-treatment and evaluated through electroneuromyography analysis of the traumatized nerve, injured nerve-related muscle strength, and two-point discrimination test. RESULTS: Impulse transmission of injured nerves to the end organ was faster in group 1. Further, ENMG parameters demonstrated that injured nerves of patients in group 1 recovered faster. Patients in group 1 also reached higher power score and had significantly more rapid motor recovery than patients in group 2. CONCLUSION: This prospective study of upper extremity injuries demonstrated the favorable effects of HBOT on nerve recovery both clinically and electrophysiologically following nerve repair. One HBOT session each day for 5 days after surgical treatment can decrease morbidity and facilitate recovery.

Fighting against infectious diseases with almost 18 million cattle spread over a wide geographical area is troublesome economically and physically. The administration of different vaccines simultaneously during the foot-and-mouth disease (FMD) vaccination campaign will help reduce both the vaccine stress of animals and the field veterinarians' workload. Diarrhea due to Escherichia coli (E. coli) is a significant problem and a major cause of mortality in calves, and thus, simultaneous application of FMD and E. coli vaccines to dams would prove efficient in field conditions. This study aimed to investigate the effect of simultaneous administration of four different locally produced gel and oil adjuvant inactivated E. coli vaccines with locally produced oil adjuvant inactivated FMD vaccine on neutralizing antibody levels and the properties of the antibodies in late-term pregnant dams and their calves. For this purpose, seven to eight-month-old pregnant dams (n = 146) were divided into two main groups to receive two doses (single and booster), or only single dose (no booster). FMD neutralizing antibody titers were evaluated by a virus neutralization test against serotype A, O, and Asia1. In addition, the properties of antibodies against serotype A were assessed by isotype and avidity ELISAs. E. coli antibodies were measured by the hemagglutination inhibition test. Results of the study revealed no safety problems in any dams after the vaccinations. On day 42, calves of the dams vaccinated simultaneously had higher neutralizing antibody titers against three serotypes than the calves of only FMD vaccinated dams. IgG1/IgG2 ratio was higher in single-dose groups than booster-dose groups against serotype A in calves. The avidity index was detected over the threshold value (24.5%). A positive correlation was found in the transmission of maternal antibodies from mothers to calves in simultaneous administration groups. In conclusion, during the FMD vaccine campaigns, FMD and E. coli vaccines can be simultaneously applied to dams in the 7th and 8th months of gestation. Results of this study has led to the inclusion of simultaneous application of FMD and E. coli vaccines in the 'Animal Disease and Animal Movement Control Program-2018' and these two vaccines have been applied in the field ever since as a solution for field veterinarians to save time and labor during vaccination.

OBJECTIVE: To compare the values of neutrophil:lymphocyte ratio (NLR), platelet:lymphocyte ratio (PLR), and mean platelet volume (MPV) with carboxyhemoglobin (COHb) and lactate levels in children with acute CO intoxication. METHODS: In this retrospective study, the patients were divided into two groups: mild-to-moderate carbon monoxide poisoning (COP) (COHb 10%-20%) and severe COP (COHb > 20%) according to the COHb levels in the application. All patients were compared in terms of NLR, PLR, and MPV parameters according to the severity of poisoning and the high lactate levels (≥ 2.2 mmol/L). RESULTS: A total of 261 children with COP were included in the study. The number of patients with mild-to-moderate COP was 183 (70.1%), and the number of patients with severe COP was 78 (29.9%). NLR [2.57 (3.27), 1.65 (1.93), (p = 0.001)] and PLR [123.0 (88.24), 92.8 (54.1), (p = 0.001)] values of mild-to-moderate COP were statistically significantly lower than the severe COP group. In the group with high lactate level, PLR values were significantly lower [120.1 (71.9), 100.2 (85.4), (p = 0.017)]. NLR and PLR values were found to be predictive of severe COP. CONCLUSION: NLR and PLR can be used for detection of clinical severity in patients with COP. PLR can be used in conjunction with lactate levels to detect tissue-level exposure in patients with COP.

Verification and validation (V&V) of systems, and system of systems, in an industrial context has never been as important as today. The recent developments in automated cyber-physical systems, digital twin environments, and Industry 4.0 applications require effective and comprehensive V&V mechanisms. Verification and Validation of Automated Systems' Safety and Security (VALU3S), a Horizon 2020 Electronic Components and Systems for European Leadership Joint Undertaking (ECSEL-JU) project started in May 2020, aims to create and evaluate a multi-domain V&V framework that facilitates evaluation of automated systems from component level to system level, with the aim of reducing the time and effort needed to evaluate these systems. VALU3S focuses on V&V for the requirements of safety, cybersecurity, and privacy (SCP). This paper mainly focuses on the elaboration of one of the 13 use cases of VALU3S to identify the SCP issues in an automated robot inspection cell that is being actively used for the quality control assessment of automotive body-in-white. The joint study here embarks on a collaborative approach that puts the V&V methods and workflows for the robotic arms safety trajectory planning and execution, fault injection techniques, cyber-physical security vulnerability assessment, anomaly detection, and SCP countermeasures required for remote control and inspection. The paper also presents cross-links with ECSEL-JU goals and the current advancements in the market and scientific and technological state-of-play.
RESUMO
Purpose: In vivo confocal microscopy (IVCM) is a noninvasive, reproducible, and inexpensive diagnostic tool for corneal diseases. However, widespread and effortless image acquisition in IVCM creates serious image analysis workloads on ophthalmologists, and neural networks could solve this problem quickly. We have produced a novel deep learning algorithm based on generative adversarial networks (GANs), and we compare its accuracy for automatic segmentation of subbasal nerves in IVCM images with a fully convolutional neural network (U-Net) based method. Methods: We have collected IVCM images from 85 subjects. U-Net and GAN-based image segmentation methods were trained and tested under the supervision of three clinicians for the segmentation of corneal subbasal nerves. Nerve segmentation results for GAN and U-Net-based methods were compared with the clinicians by using Pearson's R correlation, Bland-Altman analysis, and receiver operating characteristics (ROC) statistics. Additionally, different noises were applied on IVCM images to evaluate the performances of the algorithms with noises of biomedical imaging. Results: The GAN-based algorithm demonstrated similar correlation and Bland-Altman analysis results with U-Net. The GAN-based method showed significantly higher accuracy compared to U-Net in ROC curves. Additionally, the performance of the U-Net deteriorated significantly with different noises, especially in speckle noise, compared to GAN. Conclusions: This study is the first application of GAN-based algorithms on IVCM images. The GAN-based algorithms demonstrated higher accuracy than U-Net for automatic corneal nerve segmentation in IVCM images, in patient-acquired images and noise applied images. This GAN-based segmentation method can be used as a facilitating diagnostic tool in ophthalmology clinics. Translational Relevance: Generative adversarial networks are emerging deep learning models for medical image processing, which could be important clinical tools for rapid segmentation and analysis of corneal subbasal nerves in IVCM images.

National programs for foot-and-mouth disease (FMD) eradication includes the use of vaccination; Turkey which is endemic to FMD virus (FMDV) (except for the Thrace region) and there is a risk of incursion of exotic strains from eastern borders. In 2015, a devastating outbreak was caused by the A/ASIA/G-VII (G-VII) lineage, which led to the inclusion of a new vaccine strain (A/TUR/15) derived from this lineage in 3 months. Although most of the cattle population in Turkey was then immunized with A/TUR/15 (vaccine coverage: 92.8%), the G-VII lineage continued to cause outbreaks in the field despite the evidence of protection observed with A/TUR/15 in in vivo and in vitro tests. When G-VII field strains were examined, changes in their genomes were detected. As the lineage appeared to be evolving, an unconventional vaccination strategy was adapted which changed the vaccine strain with new variants of G-VII according to antigenic evolution. To assess the suitability of candidate vaccine strains derived from the variants of the G-VII lineage, three viral candidates were assessed (A/TUR/15, A/TUR/16 and A/TUR/17) by in vitro virus neutralization tests for r1 vaccine matching and in vivo heterologous challenge tests. Although all three vaccine strains were antigenically well matched with each other and other G-VII field viruses, due to continues outbreaks the vaccine strain was changed three times in 20 months from A/TUR/15 (Dec 2015) to A/TUR/16 (Dec 2016) and then to A/TUR/17 (Aug 2017). With this strategy serotype A has not been observed in the field since January 2018. This study highlights the importance of adapting the vaccine strains according to antigenic evolution as this could be a valuable combat strategy in endemic countries, rather than using well-known vaccine strain and relying only on the relationship coefficient (r1 ) value.

BACKGROUND: In general, capsular contracture is the underlying cause of complications such as pain, stiffening, breast asymmetry, and animation deformity that are seen in the late postoperative period due to the use of silicone breast prostheses. Considering the positive effects of HBO therapy on wound healing, the objective of this study was to investigate the effect of HBO therapy on capsule reaction occurring due to silicone implants. MATERIAL AND METHODS: Rats were divided into four groups. 1 cm × 1 cm silicone implants with rough surface were inserted in subcutaneous plane on the m spinotrapezius muscle fascia at just right of the dorsal region midline in rats in Group 1, while implants with same properties were inserted beneath m spinotrapezius muscle in rats in Group 2.Implants with the same properties were inserted in the subcutaneous area on the m spinotrapezius muscle in rats in Group 3 and into the area under the muscle in rats in Group 4. Beginning from the first postoperative day, rats in Groups 3 and 4 received HBO therapy for 90 min under 2.5 ATM pressure as one session a day over 15 days. RESULTS: The mean capsule thickness was statistically significantly lower in the groups treated with HBO compared to the control groups. Fibroblast, neutrophil and macrophage counts were statistically significantly lower in the groups treated with HBO compared to the control groups. CONCLUSION: We believe that HBO therapy can be used as an adjuvant treatment options to decrease capsule contraction occurring after silicone implant application.
