Effect of Arnica montana 6 cH on edema, mouth opening and pain in patients submitted to extraction of impacted third molars

This study had the objective to evaluate the homeopathic action of Arnica montana 6 cH and placebo on edema, mouth opening (trismus) and pain in patients submitted to extraction of bilaterally impacted lower third molars. The experiment was carried out as a crossover and double-blind study. The data showed that edema was significantly reduced by the treatment with Arnica montana 6 cH (p<0.05) and did not demonstrate significant effect on trismus and pain as compared to control group.

Edema agudo pulmonar associado à obstrução das vias aéreas. Relato de caso

BAKGROUND AND OBJECTIVES: Negative pressure pulmonary edema has been defined as non-cardiogenic edema, with transudation of fluid to the interstitial space of the lungs due to an increase in negative intrathoracic pressure secondary to obstruction of the upper airways. This is the case of a healthy patient who underwent general anesthesia and developed acute pulmonary edema after extubation. CASE REPORT: A 23-year old female patient, physical status ASA II, underwent gynecologic videolaparoscopy under general anesthesia. The procedure lasted 3 hours without intercurrence. After extubation the patient developed laryngeal spasm and reduction in oxygen saturation. The patient improved after placement of an oral cannula and administration of oxygen under positive pressure with a face mask. Once the patient was stable she was transferred to the recovery room where, shortly after her arrival, she developed acute pulmonary edema with elimination of bloody serous secretion. Treatment consisted of elevation of the head, administration of oxygen via a face mask, furosemide and fluid restriction. Chest X-ray was compatible with acute pulmonary edema and normal cardiac area. Electrocardiogram (ECG), echocardiogram and cardiac enzymes were normal. The condition of the patient improved and she was discharged from the hospital the following day, asymptomatic. CONCLUSIONS: Acute pulmonary edema associated with obstruction of the upper airways can aggravate surgical procedures with low morbidity, affecting mainly young patients. Early treatment should be instituted because it has a fast evolution and, in most cases, resolves without lasting damages. © Sociedade Brasileira de Anestesiologia, 2008.

Edema agudo de pulmão de pressão negativa como complicação grave de síndrome de apneia obstrutiva do sono em crianças. Relatos de casos

Introduction: Obstructive sleep apnea syndrome is related to cardiopulmonary complications in children. It is important to know its patophysiology and possible complications to help reduce risks in this group. Aims: To report three cases of severe cardiorespiratory complications of obstructive sleep apnea managed in the intensive care unit (ICU). Case report: Two children with no previous diagnosis of obstructive sleep apnea syndrome suffered acute congestive heart failure and acute lung oedema with need of ICU and improved after adenotonsillectomy. In a third case, the patient had acute lung oedema as a complication after adenotonsillectomy. Conclusions: Paediatricians and otolaryngologists must be aware of the clinical manifestations of severe sleep apnea. Early referring to treatment and special attention at pre and post surgical periods are essentials to avoid serious complications.

Sulfated polysaccharide extracted of the green algae Caulerpa racemosa increase the enzymatic activity and paw edema induced by sPLA2 from Crotalus durissus terrificus venom

Sulfated polysaccharides derived from seaweed have shown great potential for use in the development of new drugs. In this study, we observed that a low-molecular-weight sulfated polysaccharide from Caulerpa racemosa, termed CrSP, could interact with secretory phospholipase A2 (sPLA2) isolated from Crotalus durissus terrificus venom. When native sPLA2 (14 kDa) was incubated with CrSP, they formed a molecular complex (sPLA2:CrSP) with a molecular mass of 32 kDa, approximately. Size exclusion chromatography experiments suggested that CrSP formed a stable complex with sPLA2. We belived that sPLA2 and SPCr are involved an ionic interaction between negatively charged CrSP and the positively charged basic amino acid residues of sPLA2, because this interaction induced significant changes in sPLA2 enzymatic and pharmacological activities. CrSP caused a significant increase in sPLA2 enzymatic and bactericidal activity and increased its edematogenic effect. A pharmacological assay showed that the myotoxic activity of sPLA2:CrSP is unrelated to its enzymatic activity and that sPLA2:CrSP may have a practical application as a natural antibacterial agent for use in humans and commercially raised animals.

Limbal autograft transplantation in a dog with alkali-induced ulceration

Descreve-se um caso de um animal da espécie canina, fêmea, sem raça definida, de três meses de idade, com histórico de apatia, contato prévio com produto alcalino (hidróxido de sódio) e relutância em abrir o olho direito. Ao exame oftálmico, foram observados blefarospasmo, fotofobia, epífora, quemose discreta, hiperemia conjuntival, e edema corneal difuso com comprometimento do limbo. Foram realizados o teste da fluoresceína positivo e o Teste Lacrimal de Schirmer 32mm min-1. Com base nos achados, firmou-se o diagnóstico de úlcera por álcali e realizou-se transplante autógeno do limbo. No pós-operatório, observou-se vascularização corneal a partir do terceiro dia e sua intensificação, em número e calibre, nos dias subseqüentes. Também foram observadas mínimas áreas de transparência corneal. Os resultados obtidos permitem admitir que o transplante autógeno de limbo é procedimento factível para o manejo da terapia de úlceras de córnea por álcali.

Hemangiosarcoma of the nictitant membrane in a Brazilian Fila dog: case report

Relata-se o caso de um cão, macho, da raça Fila Brasileiro, com nove anos de idade, acometido por neoformação tecidual na membrana nictitante do olho direito, com cerca de quatro meses de evolução. Realizou-se exame oftálmico rotineiro, a partir do qual se notaram hiperemia e edema conjuntivais, secreção ocular serossangüinolenta e neoformação saliente na conjuntiva da membrana nictitante. Realizou-se a exérese cirúrgica da neoformação. À histopatologia, encontraram-se células endoteliais pouco diferenciadas e pleomórficas que originavam intensa neoformação vascular, compatíveis com hemangiossarcoma da membrana nictitante.

Eletroacupuntura aplicada nas fases precoce e tardia da cicatrização do tendão calcanear comum de coelhos após reparo tardio com peritônio bovino conservado em solução supersaturada de sal: aspectos clínicos

Para avaliar o uso da eletroacupuntura (EA) sobre os aspectos clínicos e deambulatórios, 36 coelhos tiveram o tendão calcanear comum seccionado e, após 30 dias, receberam enxerto de peritônio bovino conservado em solução supersaturada de sal. em seguida, os animais foram distribuídos aleatoriamente em três grupos de igual número: no primeiro grupo, os coelhos foram estimulados pela EA do segundo ao 11° dia de pós-operatório (PO) (E10); no segundo grupo do 11o ao 31o dia de PO (E20) e, no terceiro grupo, os animais não foram estimulados (C). Verificou-se, nos animais do E10, durante o PO, ausência de edema e hiperemia no membro tratado pela EA. Não se observou diferença significativa (P>0,05) entre os grupos quanto ao grau de deambulação dos animais. Todos os coelhos tiveram completa recuperação da deambulação até os 51 dias de PO. A utilização da eletroacupuntura na fase precoce da cicatrização do tendão calcanear comum de coelhos impediu a formação de edema e hiperemia. O tratamento com eletroacupuntura no PO não melhorou o desempenho da deambulação.
