Linfedema escrotal gigante / Giant scrotal lymphedema

RESUMEN La elefantiasis escrotal es una condición que ha sido históricamente descripta en áreas endémicas de filariasis, pero es menos frecuente su presentación idiopática o asociada a otras entidades. Presentamos un caso de elefantiasis escrotal gigante de causa adquirida idiopática, al que se le practicó la exéresis de la estructura linfedematosa y la reconstrucción del defecto con colgajos locales y autoinjerto cutáneo. El motivo de su divulgación radica en que se trata de un caso muy poco frecuente, ya sea por la baja incidencia y etiología, así como por la importante magnitud del problema para el individuo. El objetivo principal en el tratamiento del linfedema, en el caso presentado, fue devolverle al paciente funciones primarias y elementales de vida, además de disminuir la morbilidad y otorgarle una mejor calidad de vida.

ABSTRACT Scrotal elephantiasis is a condition that has been historically described in areas where filariasis is endemic, but idiopathic cases or those associated with other entities are rare. We report a case of a patient with idiopathic acquired giant scrotal elephantiasis who underwent excision of the lymphedematous structure and reconstruction of the defect with local flaps and skin autograft. The reason for this presentation is the uncommon nature of the case due to its low incidence, rare etiology and the magnitude of the problem experienced by the patient. The main goal in the treatment of lymphedema in this case was to restore primary and elementary functions of life to the patient, reduce morbidity and provide him with a better quality of life.

TWO INTERESTING CASES OF FILARIASIS AT UNCOMMON SITES

Filariasis is a condition resulting from filarial parasites that affects both humans and animals.There are several hundreds of filarial parasites which have been mentioned in medical literature, out of which only eight species are known to cause natural infections in humans. Repeated episodes of inflammation and lymphedema cause lymphatic damage, persistent edema, and elephantiasis of the legs, arms, scrotum, vulva, and breasts. We have reported two cases of filariasis at unusual sites

Coverage evaluation of Mass Drug Administration (MDA) for lymphatic filariasis in a district of Bundelkhand Region of Uttar Pradesh

Introduction: Lymphatic filariasis results in severe disability that leading to severe social and economic burden at each level from individual to family, and community. This study was carried out to assess the coverage and compliance of MDA. Methods: From 300 households (1837 individuals) in both rural & urban area were covered in coverage evaluation survey by systematic selection of subunits using probability proportionate to size (PPS). Each household was visited by WHO designated team and data were collected using predesigned questionnaire. Data was compiled on MS-excel spreadsheet, frequency and percentage were calculated. Results: The overall effective coverage for all drugs was low (19.1%). The coverage was low, compliance was higher in urban as compared to rural area. Females had better coverage and compliance than males. The primary reasons for drug not offered was nobody came to offer drug, drug not swallowed was not sick, drug swallowed was useful information from drug administrator (DA). Only one female reported adverse effect. Conclusion: Increase in coverage along with decrease in coverage-compliance gap is needed to achieve filariasis elimination that warrants intense IEC activities using different platforms, development of better drug delivery strategies and strengthening monitoring system.

Avaliação do kit Filaria Deteção; IgG4 produzido com o antígeno recombinante Wb123 para diagnóstico da filariose linfática no Brasil / Evaluation of the Filaria Detection; IgG4 kit employing recombinant Wb123 antigen for diagnosis of lymphatic filariasis in Brazil / Evaluación de pruebas de anticuerpos antifiláricos IgG4, fabricado con el antígeno recombinante Wb123, para el diagnóstico de la filariasis linfática en Brasil

RESUMO O Plano Global de Eliminação da Filariose Linfática, lançado pela Organização Mundial da Saúde em 2000, propõe o uso de testes de detecção de antígeno circulante filarial como ferramenta diagnóstica para avaliação e monitoramento das ações de controle da parasitose. Entretanto, esses testes, apesar de apresentarem alta sensibilidade, não conseguem detectar com eficiência a infecção em seu estágio inicial, quando ainda não existe a presença de helmintos adultos. Considerando essa limitação, a pesquisa de anticorpos antifilariais tem sido apontada como uma alternativa, uma vez que os anticorpos produzidos contra as larvas infectantes do parasito são detectados antes da presença de antígeno circulante filarial. O objetivo deste estudo foi definir o ponto de corte e avaliar a acurácia do kit Filaria Detect™ IgG4 produzido com o antígeno recombinante Wb123 para diagnóstico da filariose linfática no Brasil. Para isso, foi realizado um estudo de avaliação de teste diagnóstico, no qual foram utilizadas 256 amostras de soro: 79 (30,9%) obtidas de indivíduos microfilarêmicos e 177 (60,1%), de indivíduos amicrofilarêmicos e que testaram negativo para os testes imunológicos Bm14 CELISA e Og4C3 ELISA. A definição do ponto de corte ideal, bem como da acurácia do kit Filaria Detect™ IgG4, foi obtida através da construção de curvas ROC, sendo a densidade óptica de 0,239 aquela na qual o teste obteve melhor desempenho, com sensibilidade de 81,0% e especificidade de 96,6%. Os resultados obtidos demonstraram que o kit Filaria Detect™ IgG4 é uma ferramenta promissora para investigação e monitoramento de áreas submetidas ao tratamento em massa para filariose linfática.

ABSTRACT The Global Programme to Eliminate Lymphatic Filariasis, launched by the World Health Organization in the year 2000, proposes the use of circulating filarial antigen tests as a diagnostic tool to assess and monitor initiatives to control filarial infection. However, despite a high sensitivity, these tests are not efficient to detect infection at early stages, before worms have reached the adult stage. Considering this limitation, anti-filarial antibody testing has been suggested as an alternative, given that the antibodies produced against the larvae are detectable before the presence of circulating filarial antigen. The objective of the present study was to determine the diagnostic cut-off and the accuracy of the Filaria Detect™ IgG4 kit employing recombinant Wb123 antigen for diagnosis of lymphatic filariasis in Brazil. For that, we performed a diagnostic evaluation study in which 256 serum samples were analyzed: 79 (30.9%) obtained from microfilaremic individuals and 177 (60.1%) from amicrofilaremic individuals who tested negative with the Bm14 CELISA and Og4C3 ELISA immunologic tests. The ideal cutoff as well as the Filaria Detect™ IgG4 kit accuracy were determined based on ROC curve analyses, with an optical density of 0.239 identified as the cutoff with the best performance, with 81.0% sensitivity and 96.6% specificity. The results show that the Filaria Detect™ IgG4 kit is a promising tool for investigation and monitoring of areas undergoing mass drug administration for lymphatic filariasis.

RESUMEN En el programa mundial de eliminación de la filariasis linfática, puesto en marcha por la Organización Mundial de la Salud en el año 2000, se propone el uso de pruebas de detección del antígeno filárico circulante como instrumento de diagnóstico para la evaluación y el seguimiento de las medidas de control de la parasitosis. Sin embargo, esas pruebas, a pesar de tener un alto grado de sensibilidad, no permiten detectar con eficiencia la infección en su fase inicial, cuando todavía no existen helmintos adultos. En vista de esa limitación, se ha señalado como una opción el estudio de anticuerpos antifiláricos, puesto que los anticuerpos producidos contra las larvas infectantes del parásito se detectan antes de la existencia de antígeno filárico circulante. El objetivo de este estudio fue definir el punto de corte y evaluar la exactitud del estuche Detect™ para pruebas de anticuerpos antifiláricos IgG4, fabricado con el antígeno recombinante Wb123, para el diagnóstico de la filariasis linfática en Brasil. Para ello, se realizó un estudio de evaluación de la prueba diagnóstica, en el cual se utilizaron 256 muestras de suero, a saber, 79 (30,9%) obtenidas de personas microfilarémicas y 177 (60,1%) de personas amicrofilarémicas, que arrojaron resultados seronegativos en las pruebas inmunológicas CELISA Bm14 y ELISA Og4C3. La definición del punto de corte ideal y de la exactitud del estuche Detect™ se obtuvo con la construcción de curvas de la característica operativa del receptor (ROC); una densidad óptica de 0,239 marcó el mejor nivel de desempeño de la prueba, con una sensibilidad de 81,0% y una especificidad de 96,6%. Los resultados obtenidos demostraron que el estuche Detect™ es un instrumento prometedor para la investigación y el seguimiento de las regiones donde se realiza un tratamiento masivo de la filariasis linfática.

Interruption of lymphatic filariasis transmission in Manaus, a former focus of Wuchereria bancrofti in the Western Brazilian Amazon / Interrupción de la transmisión de la filariasis linfática en Manaos, anteriormente un foco de Wuchereria bancrofti en la Amazonia occidental de Brasil / Interrupção da transmissão da filariose linfática em Manaus, anteriormente um foco de Wuchereria bancrofti na parte leste da Amazônia brasileira

ABSTRACT Objective. To confirm the absence of Wuchereria bancrofti autochthonous cases in Manaus, a former focus of lymphatic filariasis in the Western Brazilian Amazon. Methods. A field survey was carried out in 2016 using immunochromatographic rapid tests (ICT card) for the detection of circulating filarial antigens in blood. The sample included a group of 3 000 schoolchildren aged 6 to 10 years enrolled in schools from different urban areas of Manaus (including the former lymphatic filariasis focus in the city) and a group of 709 adolescents and adults, between the ages of 11 and 85 years, born and raised in different areas of Manaus. Results. All of the individuals tested negative for W. bancrofti antigen. Conclusions. Although Manaus was once considered endemic, this focus no longer seems to be active for lymphatic filariasis transmission. The results of this study could support the certification by the World Health Organization of the lymphatic filariasis transmission elimination exercise in Brazil.

RESUMEN Objetivo. Confirmar la ausencia de casos autóctonos de Wuchereria bancrofti en Manaos, anteriormente un foco de filariasis linfática en la Amazonia occidental de Brasil. Métodos. En el 2016 se llevó a cabo una encuesta en el terreno con pruebas rápidas inmunocromatográficas (tiras inmunocromatográficas) para detectar antígenos filáricos circulantes en sangre. La muestra constó de un grupo de 3 000 escolares de 6 a 10 años matriculados en escuelas de diferentes zonas urbanas de Manaos (incluida la zona que anteriormente era el foco de filariasis linfática en la ciudad) y de un grupo de 709 adolescentes y adultos, de edades comprendidas entre 11 y 85 años, nacidos y criados en diferentes áreas de Manaos. Resultados. Todas las personas dieron negativo en la prueba de antígeno de Wuchereria bancrofti. Conclusiones. Aunque hubo un tiempo en que Manaos se consideraba zona endémica, parece que este foco de transmisión de la filariasis linfática ya no está activo. Los resultados de este estudio podrían brindar apoyo a la certificación de la Organización Mundial de la Salud respecto de los esfuerzos realizados en Brasil para eliminar la transmisión de la filariasis linfática.

Elefantiasis verrugosa nostra asociada a linfedema crónico y acroangiodermatitis de mali (pseudo sarcoma de Kaposi). Reporte de caso / Elephantiasis nostra verrucosa associated with chronic lymphedema and acroangiodermatitis of mali (pseudo sarcoma of Kaposi). Case report

La elefantiasis verrugosa nostra es una patología poco frecuente secundaria a linfedema crónico no filariásico, con la consecuente deformación y aumento de volumen del miembro afecto acompañado de un engrosamiento excesivo de la piel. Presentamos el caso de un paciente de sexo masculino con hiperplasia verrugosa en miembros inferiores secundaria a linfedema crónico por trastornos de la circulación venolinfática.

The elephantiasis nostra verrucosa is a rare pathology secondary to chronic non-filarial lymphedema, with the consequent deformation and volume increase of the affected limb accompanied by excessive thickening of the skin. We present the case of a male patient with verrucous hyperplasia in the lower limbs secondary to chronic lymphedema due to disorders of the venolymphatic circulation.

COVID-19: The Ivermectin African Enigma / COVID-19: El enigma de la Ivermectina en Africa

Abstract Introduction: The low frequency of cases and deaths from the SARS-CoV-2 COVID-19 virus in some countries of Africa has called our attention about the unusual behavior of this disease. The ivermectin is considered a drug of choice for various parasitic and viral diseases and shown to have in vitro effects against SARS-CoV-2. Aims: Our study aimed to describe SARS-CoV2 infection and death rates in African countries that participated in an intensive Ivermectin mass campaign carried out to control onchocerciasis and compare them with those of countries that did not participate. Methods: Data from 19 countries that participated in the World Health Organization (WHO) sponsored African Programme for Onchocerciasis Control (APOC), from 1995 until 2015, were compared with thirty-five (Non-APOC), countries that were not included. Information was obtained from https://www.worldometers.info/coronavirus/ database. Generalized Poisson regression models were used to obtain estimates of the effect of APOC status on cumulative SARS-CoV-2 infection and mortality rates. Results: After controlling for different factors, including the Human Development Index (HDI), APOC countries (vs. non-APOC), show 28% lower mortality (0.72; 95% CI: 0.67-0.78) and 8% lower rate of infection (0.92; 95% CI: 0.91-0.93) due to COVID-19. Conclusions: The incidence in mortality rates and number of cases is significantly lower among the APOC countries compared to non-APOC countries. That a mass public health preventive campaign against COVID-19 may have taken place, inadvertently, in some African countries with massive community ivermectin use is an attractive hypothesis. Additional studies are needed to confirm it.

Resumen Introducción: La baja frecuencia de casos y muertes por el virus SARS-CoV-2 COVID-19 en algunos países de África llamó nuestra atención sobre el comportamiento inusual de esta enfermedad. La ivermectina se considera un fármaco de elección para diversas enfermedades parasitarias y virales, y se ha demostrado que tiene efectos in vitro contra el SARS-CoV-2. Objetivos: Nuestro estudio tiene el objetivo describir las tasas de infección y mortalidad del SARS-CoV-2 en los países africanos que participaron en una campaña intensiva masiva de ivermectina para el control de la oncocercosis y compararlas con las de los países que no participaron. Métodos: Los datos de 19 países que participaron en el Programa Africano para el Control de la Oncocercosis (APOC) patrocinado por la Organización Mundial de la Salud (OMS), desde 1995 hasta 2015, se compararon con 35 países que no fueron incluidos (NO APOC). La información sobre casos y muertes por COVID-19 se obtuvo de la base de datos https://www.worldometers.info/coronavirus/. Se utilizaron modelos de regresión de Poisson para obtener estimaciones del efecto del estado APOC sobre las tasas acumuladas de infección y mortalidad por SARS-CoV-2. Resultados: Después de controlar diferentes factores, incluido el Índice de Desarrollo Humano (IDH), los países APOC (frente a los no APOC) mostraron una mortalidad 28% menor (razón de tasas ajustada: RR= 0.72, IC 95%: 0.67-0.78) y una tasa de infección 8% menor (RR= 0.92, IC 95%: 0.91-0.93) por COVID-19. Conclusiones: Las tasas de mortalidad e infección son significativamente más bajas en países APOC en comparación con los países no APOC. Una campaña preventiva masiva de salud pública contra el COVID-19 pudo haber tenido lugar inadvertidamente en algunos países africanos con un uso masivo de ivermectina en la comunidad es una hipótesis atractiva. Se necesitan estudios adicionales para confirmarlo.

A rare case report of large bilateral vulval elephantiasis

Elephantiasis, the result of chronic lymphedema, is characterized by gross enlargement of the limbs or genitalia. It occurs because of obstructive diseases of the lymphatic system. Genital elephantiasis is a common result of filariasis. Other causes are lymphogranuloma venereum. granuloma inguinale, carcinomas, lymph node dissection, irradiation and tuberculosis. Filarial elephantiasis of the female genitalia is extremely uncommon, about 1-2% of the total cases of filarial elephantiasis. Mrs. X, 25 years old female, P1L1, resident of a village in Bihar presented to gynaecology OPD of ABVIMS and Dr. RML Hospital on 06th January 2020 with complaint of huge progressively increasing vulval swelling since 3 years. Patient had come from Bihar for treatment. She had been showing in her native place for 2 years but now the lump had made her walking difficult. She did not give history of any drug given for treatment for filariasis. She gave history of being treated for pulmonary Koch 10 years back. On examination, there was a non- ulcerative, polypoidal growth of around 20×14×11 cm arising from bilateral labia majora and minora obstructing the vulval cleft. There was no associated lymphadenopathy or limb oedema. All the investigations were within normal limits. Microfilaria antigen testing done at night was negative. Patient was given diethylcarbamazine and excision of the lump was done on 14th February 2020. Histopathological report showed dilated lymphatics with non-caseating granulomas, consistent with filariasis. In endemic countries like India, filariasis is the commonest cause of elephantiasis; however genital filariasis in woman is very rare. Other cause could be tuberculosis which is still rarer. Early diagnosis and treatment of filariasis can eradicate this neglected tropical disease which causes disfigurement and severe morbidity as its sequelae.

Elefantiasis vulvar por filarias / Vulvar Elephantiasis by Filarias

En el año 2000, había más de 120 millones de personas infectadas por filarias en el mundo; unos 40 millones están desfiguradas e incapacitadas por la enfermedad. La infestación de los ganglios linfáticos por el parásito Wuchereira bancrofti, es la causa más frecuente del linfedema secundario. Se presenta un caso inusual de elefantiasis vulvar por filariasis. Se analizan las alternativas terapéuticas que incluyen el tratamiento farmacológico y quirúrgico, con el fin de considerar esta última como un tratamiento paliativo más que curativo tanto para el linfedema como para la cirugía reconstructiva(AU)

In 2000, there were more than 120 million people infected by filarias in the world; some 40 million are disfigured and disabled by the disease. Infestation of the lymph nodes by Wuchereira bancrofti parasite is the most frequent cause of secondary lymphoedema. An unusual case of vulvar elephantiasis due to filariasis is reprted in this paper. The therapeutic alternatives that include pharmacological and surgical treatment are analyzed, in order to consider the latter as a palliative rather than a curative treatment both for lymphedema and for reconstructive surgery(AU)

A Case of Elephantiasis Nostras Verrucosa Treated with Oral Acitretin / 대한피부과학회지

Elephantiasis nostras verrucosa (ENV) is an uncommon condition caused by repeated inflammation and lymphatic obstruction. It occurs mainly in the lower extremities and is characterized by skin changes, including hyperkeratotic mossy papules and plaques, non-pitting edema, and cobblestone-like appearances. ENV can be diagnosed based on its typical clinical manifestations (pseudoepitheliomatous hyperplasia with enlarged lymphatic spaces, fibrous tissue proliferation, and chronic inflammation) and by skin biopsy. Although ENV is difficult to treat, reduction of lymphedema and use of keratolytic agents may be helpful. To our knowledge, only three cases of ENV have been reported. However, the case of ENV treated with oral acitretin has not been reported in domestic literatures. Therefore, we report the case of a 45-year-old woman who developed ENV. She had a past history of cellulitis and was successfully treated with oral acitretin.

Clinical observation of elephantiasis myogenic cream for treatment of chronic refractory skin ulcer / 国际中医中药杂志

Objective To explore clinical efficacy of elephantiasis myogenic cream for treatment of chronic refractory skin ulcer. Methods A total of 91 chronic refractory skin ulcer patients were randomized into the treatment group (n=46) and the control group (n=45) by random number table method. Patients of control group were treated with conventional debridement, while the treatment group were treated with elephantiasis myogenic cream. The two groups were treated for 4 weeks. Clinical curative effect was evaluated after treatment. The pain score at the times of debridement and ulcer wound healing time of the two groups were compared. The FGF-2, VEGF and fiber connection (Fn) of wound secretion of the two groups before and after treatment were compared. Results Total effective rate of treatment group was 87.0％ (40/46), which was significantly higher than the control group 66.7％ (30/45), and the difference was statistically significant (χ2=5.275, P=0.022). The pain score at the time of 2 w and 4 w after treatment in the treatment group were significantly lower than those in the control group (t value were 10.456, 12.266, all Ps<0.01). After treatment, ulcer wound healing time in the treatment group were significantly lower than those in the control group (t=2.911, P=0.002). After treatment, the FGF-2 (7.72 ± 0.58 ng/ml vs. 6.37 ± 0.50 ng/ml, t=11.881), VEGF (24.85 ± 5.63 ng/ml vs. 18.75 ± 4.51 ng/ml, t=5.697) and Fn (4.15 ± 0.42 ng/ml vs. 3.47 ± 0.38 ng/ml, t=8.093) of wound secretion in the treatment group were significantly higher than those in the control group (P<0.05).There were no serious adverse reaction of the two groups during treatment. Conclusions The elephantiasis myogenic cream for treatment of chronic refractory skin ulcer has a good efficacy and low adverse reactions, can relieve patients' pain, improve the wound heal, reduce heal times.

Evaluation of Mass Drug Administration for the Elimination of Lymphatic Filariasis in Dakshina Kannada District, Karnataka

Backgroundand Aims: Lymphatic filariasis (LF) is the most debilitating and disfiguring among all diseases. The National HealthPolicy (2002) had set the goal of elimination of LF in India by 2015. The concept of mass drug administration (MDA) is to approachevery individual in the target community and administer an annual single dose of antifilarial drugs (diethylcarbamazine andalbendazole).Objectives: The objectives of this study were (1) to find the coverage and compliance of MDA at Dakshina Kannada district and (2) toassess the knowledge of responsible adult respondent regarding elephantiasis/filariasis and MDA program.Materials and Methods: The present study was conducted to evaluate the coverage and compliance of MDA in Dakshina KannadaDistrict which was held on January 23, 2012. The evaluation was conducted for 1 week by a team of investigators. A total of 232 houseswere visited randomly in four clusters (1 in urban + 3 in rural area) covering of 982 beneficiaries between the age group of 2 and 60 yearsof age in pre-designed and semi-structured pro forma.Results: The coverage of MDA was 84%, and compliance among those who received the tablets was 80.24%. There was marginallybetter coverage in urban areas (89.27%) compared to rural area (82.41%), and compliance was better in rural areas (87.94%) comparedto urban area (63.18%). The coverage compliance gap which shows why people do not consume the tablet was 3.74%, and the effectivecoverage rate was 67.41%. The coverage was maximum, i.e., 91.3% in Kalladka (cluster 3) and minimum, i.e., 76.21% in Koila (cluster 2),whereas compliance was maximum, i.e., 90.73% in Koila (cluster 2) and minimum, i.e., 63.18% in Attavara (cluster 1).Conclusion: The coverage and compliance rate in Dakshina Kannada district were 84.01% and 80.24%, respectively, with effectivecoverage rate of 67.41%. Awareness regarding MDA program was poor

Use of complex decongestive therapy with low cost material in a patient with lymphedema living in an endemic area for filariasis

Lymphatic filariasis affects millions of people around the world and may have disabling consequences. Lymphedema stands out as a chronic manifestation in patients with this disease, affecting the lower limbs and limiting motor function. This study aimed to propose a treatment protocol to decrease lower limb lymphedema of treated patients and to show the efficacy of Complex Decongestive Therapy (CDT) as an auxiliary resource for this condition. This is a case study of a patient treated with CDT, making use of compression methods with alternative materials and instructions for asepsis during 10 weeks. The results demonstrated that this treatment reduced lymphedema in the right lower limb of the patient from grade V to grade III, with areas of measurement reduction of up to 41%. In addition, acute dermatolymphangioadenitis (ADLA) manifestations stopped in the treated patient. CDT associated with low-cost compression material, has been shown to be effective in reducing lower limb lymphedema and ADLA crises, as well as in promoting improved locomotion and performance of daily activities by the patient

Pretibial Myxedema Presenting as Severe Elephantiasis

Elephantiasis is a symptom characterized by the thickening of the skin and underlying tissues in the legs. Pretibial myxedema (PTM) is a non-frequent manifestation of autoimmune thyroiditis, particularly Graves' disease. Lesions of myxedema occur most commonly on the pretibial surfaces, also develop at sites of previous injury or scars and other areas. A 49-year-old male presented with severe elephantiasis on the both pretibial areas, dorsum of the feet, ankles and toes. Twenty years previously, he had received radioactive iodine treatment for thyrotoxicosis. Laboratory tests showed that the patient's thyroid function was normal, but the level of thyroid stimulating hormone (TSH) receptor antibodies was very high (>40 IU/L). The biopsy confirmed PTM. Interestingly, the connective tissue was stained with the TSH receptor antibodies in the deep dermis. Elephantiasic PTM is a severe form of the myxedema and there is few reported case. We report a rare case of PTM with appearance of severe elephantiasis.

Intervención quirúrgica de linfedema escrotal gigante, bolivia / Surgical intervention of giant escrotal lymphedema in bolivia

Linfedema escrotal es una patología de escasa frecuencia como presentación idiopática. Se conoce también como elefantiasis por las modificaciones que produce en tejido dérmico, se clasifica de acuerdo a la edad de aparición en congénito o adquirido. El diagnóstico es clínico y la etiología se confirma con exámenes complementarios. El tratamiento recomendado es quirúrgico aunque se puede recurrir a tratamientos paliativos en casos de menor gravedad. Se presenta paciente procedente de Cochabamba-Bolivia, masculino de 33 años con cuadro de 3 años de evolución, se realizó la extirpación de 3,7 Kg de tejido escrotal linfedematoso que tras la intervención quirúrgica presentó una evolución favorable sin complicaciones, mejorando la calidad de vida del paciente y el cuadro clinico.

Scrotal Lymphedema is an infrequent pathology as an idiopathic presentation. Also, it is known as elephantiasis because of the modifications of dermic tissue, it is classified, in order to the age off apparition, in congenital or acquired. The diagnosis is clinic and the etiology could be confirmed by complementary tests. In general, the recommended treatment is surgical although with less serious cases it should appeal to palliative treatment. It is presented a case of a 33 year-old male, from Parotani, in Cochabamba-Bolivia with a clinical presentation of three years of evolution. It was made an extraction of 3,7 kg lump of lymphoedematical scrotal tissue after that he did not present complications and patient's quality of life improved.

Acitretin an Additional Treatment Option for Elephantiasis Nostras Verrucosa: A Case Report

Elephantiasis nostras verrucosa occurs due to chronic lymphedema, characterized by cutaneous changes consisting of papillomatous, verrucous, and hyperkerototic lesions. Treatment of elephantiasis nostras verrucosa is challenging and results are often disappointing. We report our experience with a patient who was successfully treated with oral acitretin.

Antifilarial actions of green tea extract and a synthetic heterocyclic thiazolidine derivative, Im8 compound in experimental mouse model.

In spite of the advances in drug development and research against human lymphatic filariasis following the WHO mandate to address the disease-associated socioeconomic burden, diethylcarbamazine (DEC, N, N-diethyl-4-methyl-1-piperazine carboxamide) is the only available antifilarial drug to date. The major obstacle for further development of antifilarial drugs is the lack of validation of candidate drugs in the experimental animal models. Both, green tea extract and a synthetic heterocyclic thiazolidine derivative (Im8; 2-chloro-N-(4-phenylthiazol-2-yl), showed efficacy of antifilarial action in our earlier in vitro study and hence, they were screened in the present study for their antifilarial potential in the BALB/c mouse filariasis model. Mice were treated with 25 mg/kg dose of either Im8 or green tea extract or DEC or only with their respective vehicles. The untreated mice served as controls. Following insertion of the micropore chamber laden with microfilariae (Mf) of Brugia malayi, the drug or vehicle was administered s.c. in mice at 12 h intervals as 4 doses. After 12 h of administration of the last dose, the micropore chambers were removed to determine the action of the treatments as the loss of Mf motility. The green tea extract showed a significant antifilarial action and Im8 showed relatively less but significant antifilarial action as compared to the respective vehicle controls. Both the green tea extract and Im8 showed higher activity than that was exerted by DEC. These results revealed a greater efficacy of green tea and thiazolidine derivative, Im8 as the novelantifilarial agents in the experimental mouse model of filariasis.

Manejo quirúrgico del linfedema escrotal severo / Surgical management of severe scrotal lymphedema

Resumen:El linfedema consiste en la retención de líquido linfático en los tejidos, causada por una obstrucción del sistema linfático. El sistema linfático devuelve el líquido intersticial al conducto torácico y este luego al torrente sanguíneo, y de allí se recircula a los tejidos. Puede ser un fenómeno aislado o no, tal como manifestación de una displasia linfática congénita (primaria), desarrollada durante la etapa tardía de linfangiogénesis; o puede ser secundario, es decir, causado por una lesión u obstrucción en los vasos linfáticos, ya sea por disección quirúrgica radical, irradiación, malignidad, linfangitis con linfagioesclerosis, trauma o causa idiopática. Los síntomas pueden incluir fatiga grave, edema focal o generalizado en algunas regiones del cuerpo, así como descoloración de la piel que recubre el linfedema y, finalmente, la deformidad, que en el caso de las extremidades inferiores se llama elefantiasis. El linfedema no solo puede causar desfiguración, sino también limitación del estilo de vida, e incluso trastornos psicológicos. Se presenta el caso de un paciente de 45 años, portador de linfedema severo (elefantiasis) de miembros inferiores crónico y del saco escrotal, valorado y manejado quirúrgicamente en el Servicio de Cirugía Plástica y Reconstructiva del Hospital México.

Abstract:Lymphedema is a localized retention of lymphatic fluid in the tissues, usually caused by a blockage of the vessels that carry lymph. The lymphatic system returns the interstitial fluid to the thoracic duct and this in turn, brings it to the bloodstream, where it is recirculated to the tissues. It may be an isolated phenomenon or not, as a manifestation of a congenital lymphatic dysplasia (primary) developed during the late stage of lymphangiogenesis; or it may be secondary, caused by an injury or blockage to the lymphatic vessels, either by radical surgical dissection, irradiation, malignancy, lymphangitis with lymphangiosclerosis, trauma or of an idiopathic cause. Symptoms may include severe fatigue, focal or generalized edema of some regions of the body, as well as discoloration of the skin overlying the affected area, and eventually deformity, which is called elephantiasis when it refers to the lower limbs. Lymphedema not only may cause disfiguration, but also can limit lifestyle, and even cause psychological disorders. We present the case of a 45-year old patient with severe chronic lower limb (elephantiasis), and scrotal sac lymphedema, who was evaluated and successfully treated by the Department of Plastic and Reconstructive Surgery at the Hospital Mexico.

Gigantic Suprapubic Lymphedema: A Case Study

We present the first case study of idiopathic gigantic suprapubic lymphedema and buried penis treated with puboscrotal reconstruction in a patient with initial extreme obesity after an extensive weight reduction (120 kg). Massive localized lymphedema of the suprapubic region should be differentiated from the scrotal type. Severe lymphedema could not resolve on its own and weight reduction does not seem to be helpful in such cases.

Targeting folate metabolism for therapeutic option: A bioinformatics approach.

Lymphatic filariasis, commonly called elephantiasis, poses a burden of estimated level of 5.09 million disability adjusted life year. Limitations of its sole drug, diethylcarbamazine (DEC) drive exploration of effective filarial target. A few plant extracts having polyphenolic ingredients and some synthetic compounds possess potential dihydrofolate reductase (DHFR) inhibitory effect. Here, we postulated a plausible link between folates and polyphenolics based on their common precursor in shikimate metabolism. Considering its implication in structural resemblance based antagonism, we have attempted to validate parasitic DHFR protein as a target. The bioinformatics approach, in the absence of crystal structure of the proposed target, used to authenticate and for virtual docking with suitable tested compounds, showed remarkably lower thermodynamic parameters as opposed to the positive control. A comparative docking analysis between human and Brugia malayi DHFR also showed effective binding parameters with lower inhibition constants of these ligands with parasitic target, but not with human counterpart highlighting safety and efficacy. This study suggests that DHFR could be a valid drug target for lymphatic filariasis, and further reveal that bioinformatics may be an effective tool in reverse pharmacological approach for drug design.
