Randomized placebo controlled trial of phytoterpenes in DMSO for the treatment of plantar fasciitis.

Plantar fasciitis is the most common cause of heel pain in adults with an overall prevalence of 0.85% in the adult population of the US, affecting over 2 million adults annually. Most current treatment modalities are not supported by sufficient evidence to recommend one particular strategy over another. Topical application of analgesics for soft tissue pain is well established, however the plantar fascia presents challenges in this regard due to thick skin, fibrotic tissue, and an often thickened fat pad. Sixty-two patients with plantar fasciitis were randomized to a placebo controlled trial testing the efficacy of a topical solution of plant terpenes containing camphor, menthol, eugenol, eucalyptol, and vanillin. Skin permeation of the mixture was enhanced with 15% dimethylsulfoxide (DMSO), 1% limonene, and rosemary oil. One ml of solution was applied topically twice daily, and pain scores evaluated on Day 0, Day 1, Day 3, and Day 10. Using the validated foot function index 78.1% of patients reported an 85% or greater decrease in their total pain score by day 10 while placebo treatment was without effect (One Way ANOVA, P < 0.01). This study adapts the treatment modality of topical analgesia for soft tissue pain to a problematic area of the body and shows therapeutic promise.ClinicalTrials.gov Identifier: NCT05467631.

In situ forming PLA and PLGA implants for the parenteral administration of Cannabidiol.

Cannabidiol (CBD) is the main non-psychotropic cannabinoid. It has attracted a great deal of interest in the treatment of several diseases such as inflammatory disorders and cancer. Despite its promising clinical interest, its administration is very challenging. In situ forming implants (ISFIs) could be a simple and cheap strategy to administer CBD while obtaining a prolonged effect with a single administration. This work aims to design, develop, and characterize for the first time ISFIs for the parenteral administration of CBD with potential application in cancer disease. Formulations made of PLGA-502, PLGA-502H, and PLA-202 in NMP or DMSO and PLA-203 in DMSO at a polymer concentration of 0.25 mg/µL and loaded with CBD at a drug: polymer ratio of 2.5:100 and 5:100 (w/w) were developed. The formulations prepared with NMP exhibited a faster drug release. CBD implants elaborated with PLGA-502 and DMSO with the highest CBD: polymer ratio showed the most suitable drug release for one month. This formulation was successfully formed in ovo onto the chorioallantoic chick membrane without exhibiting signs of toxicity and exhibited a superior antiangiogenic activity than CBD in solution administered at the same doses. Consequently, implants made of PLGA-502 and DMSO represent a promising strategy to effectively administer CBD subcutaneously as combination therapy in cancer disease.

Morphological and Neurological Impairments Induced by Chronic Administration of Dimethyl Sulfoxide in Mice.

We studied the influence of DMSO administered ad libitum with drinking water in concentrations of 0.01, 0.1, and 1% for 4 and 6 weeks on pain sensitivity, motor coordination, and myelin content in the corpus callosum of C57BL/6 mice. After 6-week administration, DMSO in all studied concentrations decreased myelin content in the corpus callosum. Moreover, 4-week administration of 0.1% DMSO and 6-week administration of 1% DMSO increased the latency to fall in the rotarod test by 3.1 (p<0.05) and 5.1 (p<0.001) times, respectively. After 4-week administration of DMSO in concentrations of 0.01 and 0.1%, the latency of the tail flick response increased by 2.1 (p<0.05) and 1.8 times (p<0.001), respectively. Administration of DMSO in concentrations of 0.01 and 1% for 6 weeks led to a decrease of this parameter by 2.7 (p<0.05) and 3.8 times (p<0.01), respectively. Thus, DMSO in all studied concentrations decreased myelin content in the corpus callosum of C57BL/6 mice and modified motor coordination and pain sensitivity of animals.

Two-Step Effective Onyx Embolization from the Occipital Artery for the Treatment of Intracranial Dural Arteriovenous Fistula: A Technical Note.

AIM: To report our experience and the technique of two-step effective Onyx embolization from occipital artery (OA) for the obliteration of dural arteriovenous fistulas (DAVFs) with OA feeders. MATERIAL AND METHODS: The medical records of patients with intracranial DAVFs treated with trans-arterial embolization (TAE) using Onyx from the OA were retrospectively reviewed. RESULTS: Seven patients were included. The methods of Onyx injection from the OA were categorized as simple Onyx injection into the shunt, and two-step embolization. Two-step embolization involved the Onyx or coil embolization of the OA distal to the branching site of the feeders in the first step, and Onyx was injected toward the target shunt in the second step. Simple Onyx injection was performed in two cases; in both cases, the residual shunt remained. By contrast, the two-step embolization technique was performed in five cases, and in all those cases, sufficient embolization of the DAVFs was achieved. CONCLUSION: Prior embolization using Onyx or coil of the distal OA helped prevent Onyx from unexpected embolization through the subcutaneous branches that were not associated with the shunt, thereby leading to effective embolization. This new two-step embolization technique from the OA may improve the obliteration rate of DAVFs with OA feeders using TAE with Onyx.

The effect of MSM in the treatment of ankle arthrosis: Is MSM as effective as methylprednisolone or hyaluronic acid?

Posttraumatic ankle osteoarthritis (PTAO) causes severe ankle and adjacent joint morbidity. We aimed to compare the treatment efficacy of previously tried and still applied intra-articular injections and oral methylsulfonylmethane (MSM) at functional and histopathological level in PTAO animal model. Thirty-two adult female Sprague-Dawley rats were divided into four groups (Group 1: Control, Group 2: 0.06 g/kg/day MSM, Group 3: 0.04 mg/µL methylprednisolone [MP], Group 4: 0.04 mg/µL hyaluronic acid [HA]). MSM was started orally between Day 0 to the end of 8 weeks. Intra-articular injections were applied to the right ankles of the subjects after surgery. All subjects were killed after radiological evaluation at the 8th week. Subsequently, functional (range of motion) and histopathological evaluation was performed. Radiological evaluation showed better results of the MP (p < 0.001) and MSM (p < 0.001) groups than the control group. Severity of osteoarthritis (OA) in the MP group was significantly less than in the HA group (p = 0.032). When the total Osteoarthritis Research Society International score was compared, the severity of OA was higher in the KS and HA groups than in the control group (p < 0.001). No significant statistical difference was found in the histopathological comparison of MSM and control group (p = 0.466). There was no difference between the groups in range of motion measurement according to the contralateral ankle joint. The radiological progression of OA was slowed in the MSM and MP groups, but significant histopathological worsening was found in the MP and HA applied groups. We suggest that the treatment methods used in daily practice need to be reviewed.

[Comparative efficacy of a combination of undenatured type II collagen, Boswellic acids, methylsulfonylmethane, vitamins C and D3 and a combination of chondroitin sulfate and glucosamine hydrochloride in the treatment of primary osteoarthritis of the knee joint].

AIM: To evaluate the efficacy of Artneo (AN) in comparison with a combination of glucosamine hydrochloride and chondroitin sulfate (GC) in patients with osteoarthritis (OA) of the knee joint (KJ). MATERIALS AND METHODS: 70 patients with stages I-III of primary knee OA were randomized into 2 groups. Participants in the 1st (n=35) took AN 1 caps/day, in the 2nd (n=35) GC according to the standard regimen. After 7, 30, 90, 180 days, the Lequesne index (severity of OA), pain when moving according to VAS, WOMAC score were assessed, after 1, 3, 6 months - quality of life SF-36 and morning stiffness, after 6 months - MRI with T2 mapping, laboratory safety indicators. RESULTS: Over the course of 6 months of use, an improvement in the WOMAC index and a decrease in pain were observed without intergroup differences, and a greater decrease in stiffness in the AN group. After 3 months, the severity of OA decreased from moderate to mild in the AN group and was significantly lower compared to the GC group; quality of life (physical component of SF-36) was higher in the AN group. After 6 months, there was an improvement in cartilage ultrastructure (T2 relaxation time) in both groups and a more pronounced reduction of the synovitis area (MRI) in the AN group (2.95 and 1.37 times in the AN and GC group, respectively). There were no clinically significant adverse reactions observed in both groups. CONCLUSION: The use of AN in patients with stage I-III primary knee OA was not inferior in efficacy to the combination of GC. Further studies with greater statistical power (sample size) and follow-up period are warranted including in real clinical practice.

A prospective randomized controlled multicentre trial comparing intravesical DMSO and chondroïtin sulphate 2% for painful bladder syndrome/interstitial cystitis

ABSTRACT Objective To compare effectiveness of intravesical chondroïtin sulphate (CS) 2% and dimethyl sulphoxide (DMSO) 50% in patients with painful bladder syndrome/interstitial cystitis (PBS/IC). Materials and methods Patients were randomized to receive either 6 weekly instillations of CS 2% or 50% DMSO. Primary endpoint was difference in proportion of patients achieving score 6 (moderately improved) or 7 (markedly improved) in both groups using the Global Response Assessment (GRA) scale. Secondary parameters were mean 24-hours frequency and nocturia on a 3-day micturition dairy, changes from baseline in O’Leary-Sant questionnaire score and visual analog scale (VAS) for suprapubic pain. Results Thirty-six patients were the intention to treat population (22 in CS and 14 in DMSO group). In DMSO group, 57% withdrew consent and only 6 concluded the trial. Major reasons were pain during and after instillation, intolerable garlic odor and lack of efficacy. In CS group, 27% withdrew consent. Compared with DMSO group, more patients in CS group (72.7% vs. 14%) reported moderate or marked improvement (P=0.002, 95% CI 0.05-0.72) and achieved a reduction in VAS scores (20% vs. 8.3%). CS group performed significantly better in pain reduction (-1.2 vs. -0.6) and nocturia (-2.4 vs. -0.7) and better in total O’Leary reduction (-9.8 vs. -7.2). CS was better tolerated. The trial was stopped due to high number of drop-outs with DMSO. Conclusions Intravesical CS 2% is viable treatment for PBS/IC with minimal side effects. DMSO should be used with caution and with active monitoring of side effects. More randomized controlled studies on intravesical treatments are needed.

Glaucoma secundário a fístula carótido-cavernosa / Secondary glaucoma following carotid cavernous fistula

RESUMO As fístulas carótido-cavernosas são uma causa rara, porém grave, de glaucoma secundário por aumento da pressão venosa episcleral. Apresenta-se um caso de uma mulher de 72 anos, negra, atendida no Hospital de Clínicas da Universidade Federal do Triângulo Mineiro (HC-UFTM) com dor, sensação de pulsação, proptose, engurgitamento episcleral e quemose em olho direito, com aumento da pressão intraocular (PIO) apesar do uso de mediação anti-glaucomatosa. Na arteriografia foi evidenciada fístula dural para o seio cavernoso à direita, com refluxo para as veias orbitárias ipsilaterais. Realizou-se tratamento com agente líquido de embolização e, após o tratamento cirúrgico, apresentou melhora completa da proptose e congestão dos vasos episclerais, porém manteve PIO aumentada e desenvolvimento de glaucoma de ângulo fechado pela presença de goniossinéquias em 270º, com controle satisfatório com medicação.

ABSTRACT Carotid-cavernous fistulas are a major cause of secondary glaucoma due to increased episcleral venous pressure. We present the case of a 72-year-old female patient, treated at the Hospital de Clínicas at the Universidade Federal do Triângulo Mineiro (HC-UFTM), with pain, proptosis, episcleral engorgement, chemosis and pulsation in the right eye, with increased intraocular pressure (IOP) on anti-glaucomatous medication.Arteriography showed dural fistula to the right cavernous sinus, with reflux to orbital veins.Treatment with liquid embolization agent was performed, following full recovery of proptosis and congestion of the episcleral vessels. However, the patient maintained increased IOP because of narrow-angle glaucoma development due to the presence of goniosynechiae in 270º, which was controlled satisfactorily with medication.

O estudo tem o objetivo de identificar efeitos indesejáveis da ribavirina, prednisona e DMSO em cães naturalmente infectados com o vírus da cinomose. Foram utilizados 60 cães apresentando quadro neurológico da cinomose com evolução de 10 dias. Os animais foram internados e receberam tratamento de suporte; foram avaliados diariamente e realizados hemograma, dosagem bioquímica e exame de urina tipo I. Os grupos 1 e 2 foram tratados com ribavirina e sua associação com DMSO; os grupos 3 e 4 com DMSO e prednisona e o grupos 5 com ribavirina e prednisona e o grupo 6 com ribavirina, prednisona e DMSO. Os animais foram anestesiados para a colheita de líquor, medula óssea e sangue, antes do tratamento para diagnóstico através da RT-PCR. As amostras negativas foram analisadas pela técnica de hn-PCR. Todos os animais apresentaram resultado positivo em pelo menos uma das duas reações. O efeito adverso da ribavirina e a sua associação com a prednisona foi a anemia hemolítica, que foi confirmada pela observação de bilirrubina na urina apenas dos cães tratados com ribavirina.

The present study aims at the identification of undesirable effects of ribavirin, predinisone and DMSO in dogs naturally infected by canine distemper virus. The research analyzed 60 dogs with clinical neurological signs and 10 days of evolution. The animals were hospitalized for the appropriate support treatment; were daily observed, and complete blood cells count, biochemical analysis, and urine exam type I were conducted. Groups 1 and 2 were treated with ribavirin and its combination with DMSO; Groups 3 and 4 treated with prednisone and DMSO, Group 5 treated with ribavirin and prednisone, while Group 6 with ribavirin, prednisone and DMSO. Before the treatment, animals were anesthetized for the cerebrospinal fluid, bone marrow and blood samples collection for the diagnosis based on RT-PCR. The negative samples were analyzed using the hn-PCR technique. All the animals presented positive results in at least one of the 2 tests. The adverse result of ribavirin and its association with prednisone was characterized by haemolytic anemia, confirmed by the evaluation of bilirrubin occurrence only in the urine of dogs treated with ribavirin.

Objective: Evaluate the efficacy of a topical treatment protocol with DMSO 50% to alleviate inflammatory processes in type 1 complex regional pain syndrome (CRPS) with a course of less than 1 year. Method: Retrospective study performed in a traumatology hospital on patients with type1 CRPS for whom a standard treatment algorithm was prescribed with stepwise administration of oral drugs and interventional techniques. Patients also received topical DMSO 50% cream as a magistral formula. The follow-up period, lasting until patient discharge, or during 1 year for persistent cases, included 6 visits: baseline, 15 days, 1 month, 3 months, 6 months, and 1 year. The evaluation was performed using a visual analogue scale (VAS) as the main efficacy variable. Secondary variables were the Likert scale for quality of life and the limb capacity variable(range of motion, strength, overall limb function). A questionnaire designed for the study wasalso given. Results: Overall decrease in VAS score in the 29 patients was 3.09 points. The Likert scale score increased by 1.36 points. The scores measuring limb capacity increased to 12.03 for range of motion and to 3 in strength with overall function rated «moderate». Conclusions: Topical application of DMSO 50% associated with a treatment algorithm decreased pain intensity according to the VAS score with results approaching absence of pain, and led to higher scores on the quality of life questionnaire. Topical DMSO 50% is an additional tool for use in treating CRPS I. Its side effects are scarce and it provides an overall sense of relief and lessens rigidity (AU)

O amitraz possui efeitos sistêmicos resultantes da atividade intrínseca com receptores adrenérgicos do tipo a-2. Nesse estudo, avaliou-se os efeitos das injeções epidurais de amitraz (0,1 e 0,4 mg.kg-1) ou DMSO 10% (5,0 mL) sobre a freqüência cardíaca (FC), pressão arterial sistólica (PAS) , freqüência respiratória (FR) , motilidade ruminal (MR), temperatura retal (TR), altura de cabeça (AC) e as latências da resposta a estímulos nociceptivos nas regiões da coxa (LECC) e coroa do casco (LRRM) de vacas. Houve uma diminuição das variáveis FC e MR nos animais que receberam amitraz. Não houve diferenças significativas na FR, PAS e AC entre os grupos estudados. A LECC e a LRRM foram maiores no grupo amitraz (0,4 mg.kg-1) entre 25 e 120 minutos. Concluiu-se que o amitraz aumenta a latência de resposta a estímulo nociceptivo, sem induzir efeitos colaterais sistêmicos severos nas doses utilizadas, por via epidural em vacas.

Ação do dimetil-sulfóxido na isquemia de retalhos randômicos de pele em ratos / The role of subcutaneous methyl-sulfoxide in a morphological study of random skin flaps in rats

Objetivo: Avaliar a ação do dimetil-sulfóxido (DMSO) na necrose distal de retalhos randômicos isquêmicos em ratos. Métodos: Foram utilizados 30 ratos machos, linhagem Wistar, peso entre 220 e 363g e idade média de 3 meses. O retalho cutâneo dorsal (8x2cm) com pedículo cranial foi descolado, reposto em seu leito e suturado com poliamida 4.0. O grupo controle-CT (n=10) não recebeu nenhuma medicação, o grupo simulado-SM (n=10) recebeu o volume de 1mL de solução salina subcutânea, dividida em dez aplicações ao longo do retalho, o grupo experimento-EX (n=10) recebeu a injeção de 1ml de DMSO 5 por cento. Após sete dias foram avaliadas as áreas de necrose distal e colhido material para o estudo histológico. Resultados: As medidas das áreas de necrose (CT=47,99, SM=58,78, EX=41,57) e as porcentagens das áreas de necrose (CT=29,98, SM=36,73, EX=23,99) mostraram-se menores no grupo Ex (p< 0,05). O estudo histológico qualitativo mostrou, no grupo Ex, maior presença de neovascularização, menor desestruturação dos anexos e do estroma conjuntivo e presença de fibroblastos em período mais precoce que nos dois outros grupos. Conclusão: O DMSO teve ação benéfica sobre os retalhos cutâneos randômicos em ratos, expressos pela menor área de necrose distal e pelo aspecto histológico de reparação tecidual mais precoce.

Efeitos da administração epidural de amitraz, xilazina ou dimetil sulfóxido em vacas / Effects of epidural injection of amitraz, xylazine or dimethyl sulfoxide in cows

Avaliaram-se os efeitos da injeção epidural de amitraz (0,4mg/kg), xilazina (0,05mg/kg) ou dimetil sulfóxido 10 por cento (5,0ml) sobre a freqüência cardíaca (FC), pressão arterial sistólica (PAS), freqüência respiratória (FR), motilidade ruminal (MR), temperatura retal (TR), altura de cabeça (AC) e latência das respostas a estímulos nociceptivos nas regiões da coxa (LECC) e coroa do casco (LRRM) de vacas. Houve diminuição da FC e da MR nos grupos xilazina e amitraz. O tratamento com xilazina resultou em alterações na FR, PAS e AC. LECC e LRRM foram maiores nos tratamentos com agonistas alfa-2. Nas doses utilizadas, o amitraz aumentou a latência de resposta a estímulo nociceptivo em menor grau que a xilazina, sem induzir efeitos colaterais sistêmicos severos, em vacas.

The impact of heterogeneity on the diagnosis and treatment of interstitial cystitis / O impacto da heterogeneidade no diagnóstico e tratamento da cistite intersticial

A cistite intersticial (CI) é uma doença cuja etiologia permanece desconhecida. A CI é um dos estados mais incômodos na prática urológica. Geralmente afeta mulheres, que apresenta sintomas de dor ao encherem a bexiga e freqüência urinária. A CI é uma síndrome heterogênea e é, freqüentemente, dividida em dois subtipos. Comparada à CI clássica, a do tipo näo-ulcerativa difere por apresentar aspectos sintomáticos, endoscópicos e histológicos diferentes, além da resposta aos vários tipos de tratamento. Esta revisäo é uma introduçäo à síndrome da CI, no que diz respeito a características clínicas e critérios de diagnóstico. Uma variedade de modalidades de tratamento têm sido sugeridas ao longo dos anos, e säo aqui revisadas e avaliadas, entre as quais estäo a hidrodistençäo da bexiga, a terapia de instilaçäo intravesical, a medicaçäo oral e a estimulaçäo elétrica transcutânea do nervo, a ressecçäo transuretral do tecido doente da bexiga, a cistectomia supratrigonal seguida de enterocistoplastia e derivaçäo urinário.
