RESUMO
BACKGROUND: This study explored the effects of hyperbaric oxygen therapy (HBOT) on hemogram, serum biochemistry and hemostatic variables in female dogs undergoing laparoscopic-assisted ovariohysterectomy (OVH). MATERIALS: Thirty adult, mixed-breed, healthy female dogs were randomly divided into the following three groups: HBOT + SURG (exposed to two absolute atmospheres (ATAs) for 45 min followed by laparoscopic-assisted OVH), HBOT (exposed to two ATAs for 45 min) and SURG (laparoscopic-assisted OVH). Blood samples were collected at T0 (at the admission), at T1, 24 h after T0 (immediately after HBOT in the HBOT + SURG and HBOT groups, and immediately before anesthetic premedication in the SURG group), and at T2, 48 h after T0 (24 h after HBOT and anesthetic premedication). METHODS: Assessments included erythrogram, leukogram, thrombogram, renal and hepatic serum biochemistry, prothrombin time (PT), activated partial thromboplastin time (APTT), buccal mucosal bleeding time (BMBT) and bloodstain area (BA) on hygroscopic paper collected at the BMBT. RESULTS: Both the HBOT + SURG and SURG groups presented neutrophilia (p ≤ 0.0039) at T2 and an increase of ALP at T2 (p ≤ 0.0493), the SURG group presented an increase in leukocyte count at T2 (p = 0.0238) and the HBOT + SURG group presented a reduction in lymphocyte count at T2 (p = 0.0115). In the HBOT + SURG group, there was a reduction in PT and APTT in relation to the baseline value (p ≤ 0.0412). CONCLUSIONS: A session of HBOT at two ATAs for 45 min did not cause changes in the BMBT or BA in healthy female dogs. Some blood parameters investigated (neutrophil and lymphocyte count, ALP, PT and APTT) were affected by the use of HBOT.
RESUMO
Resumen En la terapia con oxígeno hiperbárico (HBO) se utiliza oxígeno al 100% de concentración en una cámara presurizada con presiones supraatmosféricas, que corresponden de 2 a 3 atmósferas. Los mecanismos por los cuales funciona esta terapia se relacionan con propiedades físicas de los gases y su comportamiento fisiológico en el organismo, lo que lleva finalmente a la hiperoxia, evento fisiológico que permite la obtención de diversos efectos beneficiosos. La evidencia en medicina ha demostrado su utilidad mayormente en la enfermedad por descompresión, infecciones cutáneas graves e intoxicación por monóxido de carbono. En el ámbito de la otorrinolaringología ha probado ser útil en algunas enfermedades como la hipoacusia súbita idiopática, tanto como terapia única como asociada al uso de corticosteroides, como en la osteomielitis refractaria del oído externo, la que en conjunto con antibioticoterapia y manejo quirúrgico presenta un evidente aumento en la tasa de mejoría. Cabe mencionar que la terapia con HBO ha demostrado también beneficios en los tratamientos y complicaciones posteriores a la radiación en pacientes con cáncer de cabeza y cuello. Es importante mencionar que la terapia con HBO no está exenta de riesgos y requiere que los pacientes cumplan con características específicas para su utilización, por lo que su indicación debe ser juiciosa y en casos seleccionados.
Abstract In hyperbaric oxygen therapy, 100% pure oxygen is used in a pressurized chamber with super atmospheric pressures which correspond to 2-3 atmospheres. The mechanism by which this treatment works is related to the physical properties of gases and their physiological behavior in the body, which leads to hyperoxia, the physiological event which allows for diverse beneficial health effects. The evidence in medicine has proven its utility mainly in decompression sickness, severe skin infections and carbon monoxide poisoning. In the otolaryngology field it has been proven useful in diseases like idiopathic sudden sensorineural hearing loss, both as the only treatment and as a concurrent treatment along with corticosteroids, in malignant otitis externa which in conjunction with antibiotic treatment and a surgical approach presents a clear increase in improvement rates. It must be mentioned that hyperbaric chamber treatment has also shown benefits in radiation treatment and post radiation complications in head and neck cancer patients. It is important to note that hyperbaric oxygen therapy is not without risks and patients must meet specific criteria for it to be applied, therefore it must be indicated using careful judgement and only in necessary cases.

OBJECTIVE: To assess whether hyperbaric oxygen sessions elevate serum levels of anti-Müllerian hormone (AMH) in patients diagnosed with infertility with serum levels of less than or equal to 1 ng/dl AMH. METHODS: A study was performed on 4 patients diagnosed with infertility. Serum AMH level was measured at the beginning and end of hyperbaric oxygen sessions, and endometrial thickness was measured on endometrial cycle day 14 before and during the hyperbaric oxygen sessions. RESULTS: In two of the four patients, the serum AMH level increased by 40% and 116%. In one patient the serum AMH level was not elevated, with a serum AMH level before and after treatment of 0.1 ng/dl. The fourth patient became pregnant during the hyperbaric oxygen sessions. Endometrial thickness was not improved in any of our patients. CONCLUSIONS: This study showed that hyperbaric oxygen sessions can increase serum AMH levels, with a significant increase of 116% in one case. Therefore, this therapy can be used as an alternative treatment for patients with serum AMH levels of less than or equal to 1 ng/dl and a limited number of eggs for IVF cycles but not for patients with serum AMH levels of less than or equal to 0.1 ng/dl, as we did not observe an increase in serum AMH level in patients with an initial AMH level of 0.1 ng/dl. This study did not demonstrate improvement in endometrial growth following hyperbaric oxygen sessions.
RESUMO
Os nervos periféricos são extensões do sistema nervoso central e responsável pela interação das atividades entre as extremidades, em suas funções sensitivas e motoras. São vulneráveis aos mesmos tipos de traumas que afetam outros tecidos: contusão, compressão, esmagamento, estiramento, avulsão e laceração. As lesões de nervos periféricos situam-se entre as mais incapacitantes que acometem indivíduos em idade produtiva, em face dos múltiplos aspectos concernentes às sequelas deste tipo de afecção. Desta forma, a interrupção de continuidade da estrutura do nervo, como no caso da neurotmese, por algum tipo de trauma, resulta na interrupção de transmissão dos impulsos nervosos e na desorganização de suas atividades funcionais. Por meio da utilização da microcirurgia foi possível desenvolver técnicas reparadoras que vão desde simples neurorrafia término-terminal até sofisticados procedimentos cirúrgicos com a utilização de enxertos de nervos, veias e artérias invertidas, tubos sintéticos de materiais variados, tais como silicone e polietileno. Outro aspecto que intriga pesquisadores de todo mundo é a utilização de fatores neurogênicos capazes de acelerar ou melhorar a regeneração de nervos periféricos. A gordura autóloga tem sido continuamente referenciada pela sua abundante oferta, no próprio sitio cirúrgico, apresentando resultados promissores, visto que a adventícia dos vasos é constituída por tecido conjuntivo frouxo, rico em adipócitos. Assim, em um trauma, os neuritos oriundos do coto proximal do nervo lesado, ficam diretamente em contato com esses adipócitos. Seguindo este raciocínio, e com base em trabalhos anteriores onde foi usada veia preenchida com músculo esquelético a fresco como enxerto, decidiu-se testar a possibilidade de crescimento axonal por meio de enxerto com tubo de polietileno preenchido por tecido adiposo autólogo associado a protocolo de imersão em câmara hiperbárica, por meio de um estudo Randomizado Controlado...
The peripheral nerves are extensions of the central nervous system and are responsible for the sensory and motor functions of the limbs. These nerves are vulnerable to the same types of traumas that affect other tissues: contusion, compression, crushing, stretching, avulsion, and laceration. Amongst the most disabling kinds of injuries that affect working-age individuals are those of the peripheral nerves; due to the multifaceted characteristics of the aftereffects of the injury. The break in continuity of the nerve structure due to trauma, as in the case of neurotmesis, results in the disruption of the transmission of nerve impulses and the disorganization of their functions. Through the use of microsurgery, it was possible to develop reconstructive techniques that range from a simple end-to-end neurorrhaphy to sophisticated surgical procedures that utilize nerve grafts, inverted veins and arteries, and synthetic rods of varied materials such as silicone or porous polyethylene. Another aspect that intrigues researchers around the world is the utilization of neurogenic factors capable of accelerating or improving the regeneration of peripheral nerves. Autologous fat has been a constant reference in this field of surgery due to its abundant supply at the surgical site itself. The results are promising, as the adventitia of vessels consists of loose connective tissue rich in adipocytes. Thus in a trauma, the neurites derived from the proximal stump of the damaged nerve are in direct contact with these adipocytes. Following this reasoning, and based on previous studies where veins grafted with fresh skeletal muscle were used, we decided to conduct a randomized controlled study to test the possibility of axonal growth by means of grating with a polyethylene rod filled with autologous adipocytes associated with immersion in a hyperbaric chamber. In an attempt to recover the sciatic nerve, a rod 12 mm in length, with a diameter of 0.25 mm, and with pores...

El objetivo de este trabajo es presentar la incidencia, frecuencia, características clínicas y evolución de los pacientes con mucormicosis atendidos en el Hospital de Clínicas José de San Martín, Universidad de Buenos Aires, entre los años 1982 y 2010. Durante ese período se diagnosticaron 10 casos de mucormicosis. Los tres primeros entre 1982 y 2004 y los últimos 7 entre 2005 y 2010. La incidencia y frecuencia de esta enfermedad, para el período 1980-2004 fue 0.13 pacientes/año y 0.1 casos/10 000 egresos (IC 95%: 0.00 a 0.3) respectivamente. En el período 2005-2010 la incidencia fue 0.86 pacientes/año y la frecuencia de 1.1 casos/10 000 egresos (IC 95%: 0.5 a 2.4). Hubo nueve casos de mucormicosis rinosinuso-orbitaria, siete en pacientes con diabetes mellitus, uno en una paciente con una hemopatía maligna y neutropenia, y el restante en un paciente con HIV/sida que además estaba neutropénico y con un síndrome hemofagocítico. En una paciente se realizó el diagnóstico post mortem de mucormicosis pulmonar. El diagnóstico se efectuó por la observación de filamentos cenocíticos en los diez casos. Hubo desarrollo de mucorales en los cultivos de 8/9 pacientes; cinco Rhizopus spp y tres Mucor spp. Todos los pacientes recibieron un tratamiento inicial con anfotericina B deoxicolato, que en tres de ellos fue continuado con anfotericina B liposomal, y cirugía. Tres enfermos recibieron además un tratamiento adyuvante con oxigeno hiperbárico. La mortalidad fue 30%.(AU)
Mucormycosis is an opportunistic infection caused by fungi of the order Mucorales. It is characterized by rapid progression and high morbidity and mortality in the absence of early diagnosis and prompt treatment. It was an infrequent disease, but in recent years, its incidence appears to have increased. The aim of this paper is to report the cases of mucormycosis diagnosed from 1982 to 2010 at the Hospital de Clinicas José de San Martín, University of Buenos Aires. We diagnosed 10 cases of mucormycosis; the first three between 1982 and 2004 and the last 7 between 2005 and 2010. The incidence from 1980 to 2004 was 0.13 patient-years and the frequency 0.1/10 000 discharges (95% CI 0.00- 0.3). In the period 2005 to 2010, the incidence was 0.86 patients per year with 1.1/10 000 discharges (95% CI 0.5-2.4). There was a pulmonary mucormycosis case (in a patient treated with corticosteroids) and nine rhinocerebral cases, two in neutropenic and seven in diabetic patients. The diagnosis was made by observation of cenocytic hyphae in 10/10 patients. Mucorales were recovered in 8/9 cultures (5 Rhizopus spp and 3 Mucor spp.). In one case diagnosis of pulmonary mucormycosis was made post-mortem. Nine patients were treated with amphotericin B deoxycholate (in 3 patients supplemented with liposomal amphotericin B) and surgery. Three patients underwent hyperbaric chamber. Seven patients had favorable outcome. In conclusion, mucormycosis is a rare disease, but its incidence has increased over the past five years. A good evolution of the patients is linked to early diagnosis and treatment.(AU)

Hubo nueve casos de mucormicosis rinosinuso-orbitaria, siete en pacientes con diabetes mellitus, uno en una paciente con una hemopatía maligna y neutropenia, y el restante en un paciente con HIV/sida que además estaba neutropénico y con un síndrome hemofagocítico. En una paciente se realizó el diagnóstico post mortem de mucormicosis pulmonar. El diagnóstico se efectuó por la observación de filamentos cenocíticos en los diez casos. Hubo desarrollo de mucorales en los cultivos de 8/9 pacientes; cinco Rhizopus spp y tres Mucor spp. Todos los pacientes recibieron un tratamiento inicial con anfotericina B deoxicolato, que en tres de ellos fue continuado con anfotericina B liposomal, y cirugía. Tres enfermos recibieron además un tratamiento adyuvante con oxigeno hiperbárico. La mortalidad fue 30%.
Mucormycosis is an opportunistic infection caused by fungi of the order Mucorales. It is characterized by rapid progression and high morbidity and mortality in the absence of early diagnosis and prompt treatment. It was an infrequent disease, but in recent years, its incidence appears to have increased. The aim of this paper is to report the cases of mucormycosis diagnosed from 1982 to 2010 at the Hospital de Clinicas José de San Martín, University of Buenos Aires. We diagnosed 10 cases of mucormycosis; the first three between 1982 and 2004 and the last 7 between 2005 and 2010. The incidence from 1980 to 2004 was 0.13 patient-years and the frequency 0.1/10 000 discharges (95% CI 0.00- 0.3). In the period 2005 to 2010, the incidence was 0.86 patients per year with 1.1/10 000 discharges (95% CI 0.5-2.4). There was a pulmonary mucormycosis case (in a patient treated with corticosteroids) and nine rhinocerebral cases, two in neutropenic and seven in diabetic patients. The diagnosis was made by observation of cenocytic hyphae in 10/10 patients. Mucorales were recovered in 8/9 cultures (5 Rhizopus spp and 3 Mucor spp.). In one case diagnosis of pulmonary mucormycosis was made post-mortem. Nine patients were treated with amphotericin B deoxycholate (in 3 patients supplemented with liposomal amphotericin B) and surgery. Three patients underwent hyperbaric chamber. Seven patients had favorable outcome. In conclusion, mucormycosis is a rare disease, but its incidence has increased over the past five years. A good evolution of the patients is linked to early diagnosis and treatment.

El diagnóstico de los casos de cáncer en la región bucal son de particular interés para el odontólogo, la radioterapia se considera un instrumento para el tratamiento de estos tumores cuyo objetivo es erradicar a los mismos con la m¡nima cantidad de efectos adversos. Una consecuencia de la radioterapia es la osteorradionecrosis que es una lesión que se asienta en tejidos postirradiados en los que existe un serio compromiso hipóxico. Los protocolos de radioterapia de los tumores que se asientan en el piso de la boca, lengua y cuello, son muy agresivos, lo que aumenta la posibilidad de que provoquen la necrosis del hueso ( huesos maxilares) y tejidos adyacentes. En pacientes que presentan osteorradionecrosis existe un tratamiento que acelera el proceso de cicatrización y mejora la biodisponibilidad de los antibióticos a nivel local denominada oxigenación hiperbárica que actúa aumentando la oxigenación de los tejidos hipóxicos. El tratamiento con oxígeno hiperbárico consiste en administrar oxígeno al 100 por ciento a un individuo al que ha sometido a una presión ambiental superior a las 1,3 atmósferas absolutas, lo que se consigue en un recinto cerrado denominado cámara hiperbárica. Mediante este procedimiento terapéutico y en asociación con otras técnicas medico quirúrgicas, puedan tratarse diversas afecciones agudas y crónicas. El oxígeno hiperbárico u oxígeno administrado en ambiente presurizado, actúa como un auténtico fármaco, produciendo diferentes respuestas en función de las dosis y tiempo de administración
In the cases of cancer diagnosis in oral cavity, radiotherapy has a particular interest for the dentist as an instrument for tumor treatment therapy which main objective is to eradicate these tumors with the minimum of adverse effects. On of the consecuences of the radiotherapy is osteoradionecrosis which is an injure laying in post-irradiated tissues where there is a serious hypoxic engagement. The tumors radiotherapy protocols laying on floor of the mouth, tongue and neck are highly aggressive, this increases the possibilities of causing bone necrosis ( maxillary bones) and surround tissues. There is, for patients presenting osteoradionecrosis, a treatment which accelerates the healing process and improves the antibiotics bio-availability at a local level named hyperbaric oxygenation which acts raising oxygenation in hypoxic tissues. The hyperbaric oxygen treatment consist in administrating a 100 percent oxygen to an individual who has previously been exposed to a environmental pressure over 1,3 absolute atmospheres, this can be achieved in sealed room named hyperbaric chamber. Through this method and alongside with other medical surgical techniques several severe affections can be treated. The hyperbaric oxygen or oxygen administrated under a pressure environment work as an actual medicine (drug) producing different answers according to the dose and time administration
