Protective Effect of Mormodica balsamina Leaf Extract on the Gastric Morphology of Experimental Rats Against Ethanol Induced Gastric Ulcers / Efecto Protector de los Extractos de Hojas de Mormodica balsamina en la Morfología Gástrica de Ratas Experimentales Contra Úlceras Gástricas Inducidas por Etanol

SUMMARY: Mormodica balsamina is a valuable medicinal plant that is used to treat wounds and inflammation; its leaves are also used as an antibiotic and in the treatment of stomach pain. This study was conducted to determine the anti-ulcer activity of methanolic leaf extract of Mormodica balsamina on ethanol-induced ulcer in albino rats. A total of 32 rats were used for the study. Groups I and II served as the baseline and negative controls respectively, while groups III-VII served as the test groups. Group I was untreated, while group II received 1ml/kg body weight of the vehicle (2 % DMSO). Three test groups (III - V) received methanol extracts (75 mg, 150 mg, 300 mg/kg body weight respectively) while the other three test groups (VI - VIII) received aqueous extracts (75 mg, 150mg, 300 mg/kg body weight respectively) via oral gavage for seven days prior to ulcer induction. The rats were sacrificed, stomachs excised and ulcers scored. Histological sections were produced and examined. Findings revealed that M. balsamina extracts protected the rats' gastric epithelia from ethanol induced ulceration to varying degree with the high dose (150 and 300 mg/kg) of both extracts offering the best preservation (42 % and 50 % ulcer protective index respectively) when compared to untreated animals. Histological findings correlated with calculated ulcer indices, with treated animals having less severe gastric mucosal lesions. In conclusion, extracts of M. balsamina may possess reasonable antiulcer activities in rats against ethanol induced gastric ulcer.

Mormodica balsamina es una valiosa planta medicinal que se utiliza para tratar heridas e inflamaciones; sus hojas también se utilizan como antibiótico y en el tratamiento del dolor de estómago. Este estudio se realizó para determinar la actividad antiulcerosa del extracto metanólico de hojas de Mormodica balsamina sobre la úlcera inducida por etanol en ratas albinas. Se utilizaron un total de 32 ratas para el estudio. Los grupos I y II sirvieron como referencia y controles negativos respectivamente, mientras que los grupos III-VII sirvieron como grupos de prueba. El grupo I no se trató, mientras que el grupo II recibió 1 ml/kg de peso corporal del vehículo (2% de DMSO). Tres grupos de prueba (III - V) recibieron extractos de metanol (75 mg, 150 mg, 300 mg/ kg de peso corporal respectivamente) mientras que los otros tres grupos de prueba (VI - VIII) recibieron extractos acuosos (75 mg, 150 mg, 300 mg/kg de peso corporal respectivamente) por sonda oral durante siete días antes de la inducción de la úlcera. Se sacrificaron las ratas, se extirparon los estómagos y se puntuaron las úlceras. Se realizaron y examinaron secciones histológicas. Los resultados revelaron que los extractos de M. balsamina protegieron el epitelio gástrico de las ratas de la ulceración inducida por etanol en diversos grados, y la dosis alta (150 y 300 mg/kg) de ambos extractos ofreció la mejor conservación (42 % y 50 % de índice de protección contra úlceras, respectivamente) en comparación con los animales no tratados. Los hallazgos histológicos se correlacionaron con los índices de úlcera calculados, y los animales tratados tenían lesiones de la mucosa gástrica menos graves. En extractos de M. balsamina puede poseer actividades antiulcerosas razonables en ratas contra la úlcera gástrica inducida por etanol.

Effectiveness of 6 weeks of vestibular exercises as adjunctive therapy in the management of depression, anxiety, and stress in gastric ulcer patients

Background: Vestibular stimulation was reported to inhibit the stress axis and brings individual stress to lower levels. This is very beneficial as the management of psychological factors is equivalently important in the management of peptic ulcers. Aims and Objectives: The present study was undertaken to observe the effectiveness of vestibular exercises in the management of depression, anxiety, and stress in gastric ulcer patients. Materials and Methods: A total of 20 gastric ulcer patients without severe complications were part of the study after obtaining written informed consent. After recruiting, the participants were randomly assigned into two groups with ten participants in each group. Standard vestibular exercises mentioned in the literature were adopted. Each session of exercises comprises 45 min. Two sessions per week were administered to the participants for a period of 1 month. Results: Depression, anxiety, and stress scores were not significantly different between the control and intervention groups before the intervention. There was a significant decrease in depression, anxiety, and stress in the intervention group followed by the intervention. Conclusion: The present study results showed the beneficial effects of vestibular exercises in the management of negative psychological emotions such as depression, anxiety, and stress in patients with gastric ulcers. There is a need for large-scale studies in this area to recommend the adoption of vestibular stimulation in the management of gastric ulcers.

The effect of social determinants of health on severity of microbial keratitis presentation at a tertiary eye care hospital in Southern India

Purpose: Understanding the association between social determinants of health (SDoHs) and microbial keratitis (MK) can inform underlying risk for patients and identify risk factors associated with worse disease, such as presenting visual acuity (VA) and time to initial presentation. Methods: This was a cross?sectional study was conducted with patients presenting with MK to the cornea clinic at a tertiary care hospital in Madurai, India. Patient demographics, SDoH survey responses, geographic pollution, and clinical features at presentation were collected. Descriptive statistics, univariate analysis, multi?variable linear regression models, and Poisson regression models were utilized. Results: There were 51 patients evaluated. The mean age was 51.2 years (SD = 13.3); 33.3% were female and 55% did not visit a vision center (VC) prior to presenting to the clinic. The median presenting logarithm of the minimum angle of resolution (logMAR) VA was 1.1 [Snellen 20/240, inter?quartile range (IQR) = 20/80 to 20/4000]. The median time to presentation was 7 days (IQR = 4.5 to 10). The average particulate matter 2.5 (PM2.5) concentration, a measure of air pollution, for the districts from which the patients traveled was 24.3 ?g/m3 (SD = 1.6). Age? and sex?adjusted linear regression and Poisson regression results showed that higher levels of PM2.5 were associated with 0.28 worse presenting logMAR VA (Snellen 2.8 lines, P = 0.002). Patients who did not visit a VC had a 100% longer time to presentation compared to those who did (incidence rate ratio = 2.0, 95% confidence interval = 1.3–3.0, P = 0.001). Conclusion: Patient SDoH and environmental exposures can impact MK presentation. Understanding SDoH is important for public health and policy implications to mitigate eye health disparities in India.

Efecto de la inmunidad celular en el tratamiento de las úlceras del pie diabético con Heberprot-P® / Effect of cellular immunity in the treatment of diabetic foot ulcers with Heberprot-P®

Introducción: Los diabéticos muestran una disminuida función del sistema inmune. Su complicación más temida es la aparición de las úlceras del pie. El Heberprot-P® tiene efectos beneficiosos en la curación de estas úlceras. Objetivo: Evaluar el efecto de la inmunidad celular en el tratamiento de las úlceras del pie diabético con Heberprot-P®. Métodos: Se realizó un estudio observacional, prospectivo, de serie de casos, en 30 pacientes con úlcera de pie diabético, ingresados en el Instituto Nacional de Angiología y Cirugía Vascular. Se administraron 75 µg de Heberprot-P®, tres veces por semana, a través de vías peri- e intralesional, durante ocho semanas. Se evaluaron las variables edad, sexo, glucemia en ayunas, creatinina, urea, ácido úrico, prueba de hipersensibilidad retardada, porcentaje de granulación, tiempo de cierre de la lesión y localización de la úlcera, antes de comenzar el tratamiento, a las 4 y 8 semanas. Resultados: Se precisó un predominio del 60 por ciento en el sexo femenino y del color de piel blanca. Los niveles de glucemia y creatinina se comportaron más elevados en los anérgicos; la urea fue similar tanto en anérgicos como en reactivos; y el ácido úrico resultó mayor en hombres reactivos y en mujeres anérgicas. Hubo mayor proporción de reactivos (63,6 por ciento), que en la cuarta semana presentaron un tejido de granulación igual o mayor al 50 por ciento; y a la octava, igual o mayor al 70 por ciento. Conclusiones: La condición en los pacientes diabéticos de ser reactivo a las pruebas de hipersensibilidad retardada con úlcera de pie diabético de tipo neuropática, tratados con Heberprot-P®, está asociada directamente con una mejor respuesta en la cicatrización de sus lesiones, mediante la formación del tejido de granulación, que favorece el cierre total o parcial de la lesión. Esto no ocurrió con los pacientes anérgicos a dicha prueba(AU)

Introduction: Diabetics show decreased immune system function. Its most feared complication is the appearance of foot ulcers. Heberprot-P® has beneficial effects in healing these ulcers. Objective: To assess the effect of cellular immunity in the treatment of diabetic foot ulcers with Heberprot-P®. Methods: An observational, prospective, case series study was conducted in 30 patients with diabetic foot ulcer admitted to the National Institute of Angiology and Vascular Surgery. 75 µg of Heberprot-P®, three times a week, were administered through peri- and intralesional routes, during eight weeks. The variables age, sex, fasting blood glucose, creatinine, urea, uric acid, delayed hypersensitivity test, percentage of granulation, time of closure of the lesion and location of the ulcer, before starting treatment, at 4 and 8 weeks were evaluated. Results: A predominance of 60 % in females and white skin color were specified. Blood glucose and creatinine levels behaved higher in the anergics; urea was similar in both anergics and reagents; and uric acid was higher in reactive men and anergic women. There was a higher proportion of reagents (63.6 por ciento), which in the fourth week presented a granulation tissue equal to or greater than 50 por ciento; and at the eighth week, it was equal to or greater than 70 por ciento. Conclusions: The condition of being reactive to delayed hypersensitivity tests in diabetic patients with diabetic foot ulcer of neuropathic type, treated with Heberprot-P® is directly associated with a better response in the healing of their lesions, through the formation of granulation tissue, which favors the total or partial closure of the lesion. This did not occur with patients who were anergic to this test(AU)

Resultados de los pacientes operados de queratoplastia terapéutica en la provincia de Matanzas

Introducción: la queratoplastia terapéutica se define como un procedimiento cuyo propósito es contribuir a erradicar o reducir la infección cuando la terapia médica máxima no es eficaz para lograr este fin. Objetivo: evaluar la evolución y resultados de los pacientes operados de queratoplastia terapéutica. Materiales y métodos: se realizó un estudio descriptivo transversal en un universo de 15 pacientes con diagnóstico de úlcera grave corneal. Dichos pacientes fueron operados de queratoplastia terapéutica en el Servicio de Córnea del Hospital Universitario Comandante Faustino Pérez Hernández, de la provincia de Matanzas, entre abril de 2017 y febrero de 2020, y dieron su consentimiento informado para participar en la investigación. Resultados: predominó el sexo masculino, con un 53,3 % y una media de edad de 58,8 años. Como factores predisponentes, prevaleció el antecedente de trauma en el 33,3 %, seguido del uso de lentes de contacto y la diabetes mellitus como enfermedad sistémica asociada. Las úlceras de etiología micótica predominaron en el 26,6 % de los casos; la perforación corneal y el descemetocele se presentaron en el 40 % y 26,6 % de los pacientes respectivamente. Durante el primer mes, las complicaciones postoperatorias más frecuentes fueron la recidiva de la sepsis y la necrosis del injerto. Por su parte, la opacidad y vascularización corneal fueron las secuelas más frecuentes. Conclusiones: la demora en iniciar el protocolo de tratamiento adecuado provoca cuadros severos de la enfermedad, realizando queratoplastia "en caliente" en córneas perforadas o con necrosis, que devienen complicaciones postoperatorias y secuelas no alentadoras para los pacientes.

Introduction: therapeutic keratoplasty is defined as a procedure whose purpose is to help eradicate or reduce the infection when maximum medical therapy is not efficacious to achieve this end. Objective: to evaluate the evolution and results of the patients operated on therapeutic keratoplasty. Materials and methods: a cross-sectional, descriptive study was carried out in a universe of 15 patients with a diagnosis of severe corneal ulcer. The patients underwent therapeutic keratoplasty surgeries in the Cornea Service of the Clinical Surgical University Hospital Comandante Faustino Perez Hernandez, in the province of Matanzas, between April 2017 and May 2020, and gave their informed consent to participate in the research. Results: male gender predominated, with 53.3% and a mean age of 58.8 years. As predisposing factors, trauma antecedent predominated in 33.3%, followed by the use of contact lenses and diabetes mellitus as associated systemic disease. Ulcers of mycotic etiology predominated in 26.6% of the cases; corneal perforation and descemetoceles occurred in 40% and 26.6% of the cases respectively. During the first month, the most frequent postsurgery complications were recidival sepsis and graft necrosis. On the other hand, corneal opacity and vascularization were the most frequent sequels. Conclusions: the delay in initiating the adequated protocol treatment causes severe symptoms of the disease that lead to "in hot" keratoplasty in perforated or necrosed corneas, causing postsurgery complications and non-encouraging sequels for patients.

Nuestro objetivo fue describir las características clínicas y evolución de los pacientes con COVID-19 grave que requirieron este procedimiento. Evaluar la relación entre factores de riesgo y mortalidad. Material y métodos: Estudio descriptivo retrospectivo observacional. Se incluyeron los pacientes mayores de 18 años con COVID-19 bajo asistencia respiratoria mecánica que requirieron decúbito prono. Se efectuó seguimiento durante 28 días. Se registraron las complicaciones asociadas al decúbito prono. Se analizaron factores asociados a la mortalidad utilizando regresión de Cox. Resultados: Se realizó decúbito prono en 28 pacientes. La edad promedio fue de 52,43 años y una mediana de índice de Charlson de 1 [0,00, 2,00]. La mediana de días de asistencia respiratoria mecánica fue de 17,00 [RIQ 13,00, 23,00] y un 28,6% logró ser extubado. La mediana de días en UTI fue de 19,50 [RIQ 14.00, 23.50] con una mortalidad del 53,6%. El 35,7% necesitó dos ciclos de decúbito prono con una duración predominante de 24-36 h. El 89,4% tuvo lesiones de úlceras por presión. Los que fallecieron tuvieron menos días de UTI (16 vs. 28; p = 0,006) y solo uno de ellos había logrado ser extubado (1 vs. 7, p = 0,011). No se encontraron factores asociados a la mortalidad en la regresión de Cox. Conclusión: La población estudiada resultó predominantemente masculina y de edad promedio cercana a la quinta década de vida, con una mortalidad aproximada al 50%. No se encontró relación estadísticamente significativa entre factores de riesgo y mortalidad.

Introduction: Prone positioning (PP) was the most used strategy in patients with CO VID-19 and refractory hypoxemia. Our objective was to describe the clinical character istics and evolution of patients with severe Covid-19 who required this procedure. Also to evaluate the relationship between risk factors and mortality. Materials and method: Observational retrospective descriptive study. Patients older than 18 years old with COVID-19 under mechanical ventilation (AVM) who required PP were included. Follow-up was carried out for 28 days. Complications associated with PP were recorded. Factors associated with mortality were analyzed using Cox regression. Results: Prone position was performed in 28 patients. The average age was 52.43 years and a median Charlson Score of 1 [0.00, 2.00]. The median number of days of AVM was 17.00 [IQR 13.00, 23.00] and 28.6% managed to be extubated. The median number of days in the ICU was 19.50 [IQR 14.00, 23.50] with a mortality of 53.6%. 35.7% needed 2 PD cycles with a predominant duration of 24-36 hours. 89.4% had pressure ulcers. Those who died spent fewer days in ICU (16 vs 28; p=0.006) and only one of them had managed to be extubated (1 vs 7, p = 0.011). No factors associated with mortality were found in the Cox regression. Conclusion: The study population consisted predominantly of males in an average age close to the fifth decade, with an approximate mortality of 50%. No statistically significant relationship was found between risk factors and mortality.

NECROTIZING SIALOMETAPLASIA OF PALATE A RARE CASE REPORT

Necrotizing sialometaplasia (NS) is a rare benign reactive necrotizing in?ammatory process that affects the minor salivary gland and frequently mimics cancer on both a clinical and histopathological level. Case Study : We report the case of a 21-year-old healthy man who had throat pain and non-healing ulcer over soft palate for the past one month, with pain during swallowing.Histopathological analysis and an incisional biopsy were performed on the patient. Necrotizing sialometaplasia was the histologically determined diagnosis. Necrotizing sialometaplasia is a self-limiting disorder of salivary glands mostly affecting the hard palate.The duration of the healing process is usually related to the size of the lesion.The recurrence rate of Necrotizing Sialometaplasia is low.Even a full thickness palatal lesion heals completely within 6 months.

Photodynamic therapy for infected foot ulcers in people with diabetes mellitus: a systematic review

ABSTRACT BACKGROUND: Ulceration of the feet in patients with diabetes is a frequent complication that increases morbidity, mortality, hospitalization, treatment costs, and non-traumatic amputations. OBJECTIVE: To present a systematic review of the treatment of patients with diabetes mellitus and infected foot ulcers using photodynamic therapy. DESIGN AND SETTING: A systematic review was performed in the postgraduate program in nursing at the Universidade da Integração Internacional da Lusofonia Afro-Brasileira, Ceará, Brazil. METHODS: PubMed, CINAHL, Web of Science, EMBASE, Cochrane Library, Scopus, and LILACS databases were screened. The methodological quality, risk of bias, and quality of evidence of each study were assessed. Review Manager was used for the meta-analysis. RESULTS: Four studies were included. They highlighted significantly better outcomes in patient groups treated with photodynamic therapy than those in the control groups that were treated with topical collagenase and chloramphenicol (P = 0.036), absorbent (P < 0.001), or dry covers (P = 0.002). Significant improvements were noted in terms of the microbial load in the ulcers and tissue repair, with a reported reduction in the need for amputation by up to 35 times. Photodynamic therapy resulted in significantly better outcomes between the experimental and control groups (P = 0.04). CONCLUSION: Photodynamic therapy is significantly more effective in treating infected foot ulcers than standard therapies.

La Diabetes Mellitus es una enfermedad crónica que afecta a millones de personas en todo el mundo causando problemas socioeconómicos y emocionales; una de las complicaciones más temidas de la enfermedad son las úlceras crónicas por pie diabético (UCPD), ya que constituyen una de las principales causas de amputación de miembros inferiores, la prevalencia más alta se halló en Norteamérica (13%), en Bolivia la diabetes tipo 2 tuvo una prevalencia nacional para adultos de 6,5% y de ellos aproximadamente el 20% desarrollaron las UCPD. Por ello, fue indispensable contar con un tratamiento efectivo que evite la cronicidad, infección y amputación del miembro afectado por las úlceras. El Plasma rico en plaquetas es un producto derivado de la sangre con varios elementos que intervienen en la regeneración de tejidos y con efectos antiinflamatorios en varias lesiones; por tal motivo, surge como una opción promisoria para el tratamiento de las UCPD sin importar el grado de lesión (grados de Wagner).Para exponer sus beneficios y considerarlo como tratamiento de primera línea, se efectuó una revisión sistemática, con objetivos de carácter descriptivo-exploratorio; la recolección de la literatura se realizó de fuentes primarias (últimos 5 años), secundarias y terciarias. Finalmente, tras el análisis de los resultados se concluye indicando que el PRP como tratamiento disminuye el tiempo de curación de las úlceras del pie diabético, riesgo de infección, etc.

Diabetes Mellitus is a chronic disease that affects millions of people around the world, causing socioeconomic and emotional problems; one of the most feared complications of the disease are chronic diabetic foot ulcers (UCPD), since they constitute one of the main causes of lower limb amputation, the highest prevalence was found in North America (13%), in Bolivia the Type 2 diabetes had a national adult prevalence of 6.5%, and approximately 20% of them developed UCPD. Therefore, it was essential to have an effective treatment that prevents chronicity, infection and amputation of the limb affected by ulcers. Platelet-rich plasma (PRP) is a blood-derived product with several elements involved in tissue regeneration and with anti-inflammatory effects on various lesions; For this reason, it emerges as a promising option for the treatment of UCPD regardless of the degree of injury (Wagner grades). To expose its benefits and consider it as first-line treatment, a systematic review was carried out, with descriptive-exploratory objectives; the literature was collected from primary (last 5 years), secondary and tertiary sources. Finally, after analyzing the results, it is concluded that PRP as a treatment decreases the healing time of diabetic foot ulcers, the risk of infection, etc.

Advances in the treatment of diabetic ulcers by Chinese herbal extracts / 药学实践杂志

Skin ulcers are the most prevalent consequence of diabetes mellitus, and people with diabetic ulcers have a substantially greater death risk than those who do not have ulcers. Herbal medications have gained wide concern in recent years due to their multi-component, multi-target, and multi-pathway synergistic therapeutic effects. Clinical trials have demonstrated the safety and efficacy of herbal treatments in diabetic refractory ulcers. To systematically evaluate the healing effect of herbs on diabetic wounds, a literature search was conducted, the mechanism of action of 15 herbal extracts in promoting diabetic wound healing were reviewed, and the classification based on traditional Chinese medicine theory was discussed, which could provide a reference for the precise treatment and exploitation of herbal medicines for diabetic ulcers.

Advances of chronic enteropathy associated with SLCO2A1 gene / 国际儿科学杂志

Chronic enteropathy associated with solute carrier organic anion transporter family member 2A1 gene(CEAS)is an autosomal recessive disease caused by SLCO2A1 gene mutation.Characterized by Persistent, intractable, nonspecific intestinal ulcers that lead to chronic loss of blood and protein.At present, pathogenesis of CEAS is still unclear.Endoscopic examination shows specific intestinal ulcers and intestinal stenosis, which mainly involves ileum.Due to its rare occurrence and similar clinical manifestations with Crohn′s disease and non-steroidal anti-inflammatory drug related bowel disease, it is easy to be confused clinically.No effective treatment has been established, and iron supplementation, blood transfusion and parenteral or enteral nutrition can be given symptomatic treatment.Surgical treatment is feasible in serious condition, however, all of them can only get a temporary effect.Usually, after the end of treatment, the disease relapses, and the life prognosis is not clear.

Bone marrow-derived mesenchymal stem cell-conditioned medium ameliorates diabetic foot ulcers in rats

Abstract Objectives: This study aimed to explore the effects of bone marrow-derived Mesenchymal Stem Cell-Conditioned Medium (MSC-CM) treating diabetic foot ulcers in rats. Methods: Models of T2DM rats were induced by a high-fat diet and intraperitoneal injection of STZ in SD rats. Models of Diabetic Foot Ulcers (DFUs) were made by operation on hind limbs in diabetic rats. Rats were divided into four groups (n = 6 for each group), i.e., Normal Control group (NC), Diabetes Control group (DM-C), MSC-CM group and Mesenchymal Stem Cells group (MSCs). MSC-CM group was treated with an injection of conditioned medium derived from preconditioned rats' bone marrow MSCs around ulcers. MSCs group were treated with an injection of rats' bone marrow MSCs. The other two groups were treated with an injection of PBS. After the treatment, wound closure, re-epithelialization (thickness of the stratum granulosums of the skin, by H&E staining), cell proliferation (Ki67, by IHC), angiogenesis (CD31, by IFC), autophagy (LC3B, by IFC and WB; autoly-sosome, by EM) and pyroptosis (IL-1β, NLRP3, Caspase-1, GSDMD and GSDMD-N, by WB) in ulcers were evaluated. Results: After the treatment wound area rate, IL-1β by ELISA, and IL-1β, Caspase-1, GSDMD and GSDMD-N by WB of MSC-CM group were less than those of DM group. The thickness of the stratum granulosums of the skin, proliferation index of Ki67, mean optic density of CD31 and LC3B by IFC, and LC3B by WB of MSC-CM group were more than those of DM group. The present analysis demonstrated that the injection of MSC-CM into rats with DFUs enhanced the wound-healing process by accelerating wound closure, promoting cell proliferation and angiogenesis, enhancing cell autophagy, and reducing cell pyroptosis in ulcers. Conclusions: Studies conducted indicate that MSC-CM administration could be a novel cell-free therapeutic approach to treat DFUs accelerating the wound healing process and avoiding the risk of living cells therapy.

BehÒ«et's disease: A diagnostic challenge

BehÒ«et's disease is a low prevalence disorder that is difficult to diagnose. Its forms of presentation are often confused with infectious processes that involve multiple treatments and prolonged hospital stays. This article presents the case of a 30-year-old man who consulted with non-specific symptoms that represented a diagnostic challenge for the medical team.

Vasculitis cutánea paraneoplásica asociada a linfomadifuso de célulasB grandes / Paraneoplastic cutaneous vasculitis associated with diffuse large B-cell non-Hodgkin's lymphoma

Resumen Los fenómenos cutáneosparaneoplásicos son heterogéneos, infrecuentes y adquiridos, caracterizados por la presencia subyacente de una neoplasia. La manifestacióncutánea más frecuentemente descripta de la vasculitis paraneoplásica es la púrpura palpable. También puede manifestarse como urticaria, eritema y úlceras de miembros inferiores. Se presenta el caso de un paciente de 38 años con diagnóstico de linfoma difuso de células B grandes y úlceras atípicas de aparición concomitantepor vasculitis leucocitoclástica como fenómeno paraneoplásico. Estas lesiones suelentener un curso paralelo a la neoplasia por lo que al realizar tratamiento de la misma pueden remitir, no así cuando se realiza únicamente tratamiento para las lesiones cutáneas. Remarcamos la importancia de conservar un lecho vital y en estado de granulaciónque acompañeal tratamiento general, para así favorecer una rápida epitelización y prevención de infecciones intercurrentes.

Abstract Paraneoplastic cutaneous phenomena are heterogeneous, infrequent and acquired, characterized by the underlying presence of a neoplasm. The most frequently described cutaneous manifestation of paraneoplastic vasculitis is palpable purpura. It can also manifest as urticaria, erythema and ulcers of the lower limbs. We present the case of a 38-year-old patient with a diagnosis of diffuse large B-cell lymphoma and atypical ulcers of intercurrent onset due to leukocytoclastic vasculitis as a paraneoplastic phenomenon. These lesions usually have a parallel course to the neoplasm, so when the neoplasm is treated they may remit, but not when only the cutaneous lesions are treated. We emphasize the importance of preserving a vital tissue in a state of granulation that accompanies the general treatment, in order to favor a rapid epithelialization and prevention of intercurrent infections.

Objective: To describe the anesthetic management of a patient with Behçet's disease. Case presentation: The case is reported of a 52-year-old male patient with an individual history of Behçet's disease, who receives general anesthesia for removal of left cervical metastatic adenopathy from a hidden primary carcinoma. Conclusions: Keeping the steroid therapy, using calcium nadroparin, together with other measures for preventing deep vein thrombosis; careful airway management, eye and joint protection, as well as attention to pressure points and pathergy prevention are fundamental elements for the management of these patients.

A safer alternative approach to penetrating keratoplasty in opaque corneas

Background: This video demonstrates a useful technique of keratoplasty which can be routinely undertaken by all surgeons when imaging modalities such as anterior segment optical coherence tomography are not available and prior patient history is not forthcoming. Purpose: To demonstrate a technique of lamellar separation and layer by layer removal of host cornea when dealing with keratoplasty in perforated corneal ulcers, adherent leucomas, dense corneal opacities, which obscure visualization of the iris and anterior chamber details. Synopsis: In this video, we demonstrate penetrating keratoplasty in a failed opacified graft with iridocorneal adhesions, with no visualization of anterior chamber details. Lamellar dissection of the host cornea is done starting at its periphery and moving centrally, with gentle peeling of the superficial layers, the epithelium and bulk of stroma, following which, the deeper portion of the cornea is dissected and separated from underlying adherent iris tissue. Layer by layer separation allows better visualization through the remaining thin layers of the cornea. This permits fine dissection and layered removal of the cornea, thereby avoiding injury to iris and lens. Debulking of the host cornea decreases the force that is needed to be applied to separate adherent iris tissue from the host cornea, and reduces the chances of sudden entry into the anterior chamber and subsequent damage to the iris or lens. This also reduces the chance of iris tears, iridodialysis and bleeding from the iris and helps maintain iris integrity, which is essential intraoperatively for protection of lens and anterior chamber formation, and to avoid glare and photophobia postoperatively. Preventing iris damage also reduces the chances of formation of peripheral anterior synechiae (PAS), which can predispose to graft rejection, graft failure and secondary glaucoma. Highlights: Layer by layer corneal separation beginning inside the graft host junction, careful separation of iridocorneal adhesions and PAS is a helpful technique to optimally preserve the anterior segment anatomy during difficult cases of penetrating keratoplasty.
