COVID-19 related acute genital ulcer: a case report

ABSTRACT Acute vulvar ulcer (Lipschütz's ulcer) is a rare lesion with local hyperimmunoreactivity triggered by infection, which is characterized by acute, painful, and necrotic ulcerations. This condition is usually found in non-sexually active adolescents, and it resolves spontaneously. We report a case of a 35-year-old woman who was diagnosed with COVID-19 who did not have severe symptoms, but had high levels of D-dimer for 9 days. The COVID-19 diagnosis was followed by the appearance of an acute, necrotic, extremely painful vulvar ulcer, although symptoms caused by COVID-19 had improved. We emphasize the importance of the differential diagnosis to exclude diseases such as Behçet's syndrome, Sexually Transmitted Infections, as well as the presence of viruses that generally trigger Lipschütz's ulcer, such as Epstein-Barr virus and cytomegalovirus. No treatment is usually necessary, however, in the present report due to the pain experienced by the patient, we successfully used oral prednisone.

Ulceración esofágica por ingestión de doxiciclina / Doxycycline induced esophageal ulceration

La ulceración esofágica por ingestión de doxiciclina es una de las causas más frecuentes de lesión esofágica. Ha sido subdiagnosticada y escasamente reconocida en dermatología. El dolor retroesternal, la odinofagia de aparición brusca y el antecedente de ingesta de doxiciclina u otros fármacos son características que facilitan su diagnóstico. Puede presentar complicaciones serias, como hemorragias, estenosis y mediastinitis.

Esophageal ulceration due to ingestion of doxycycline is one of the most frequent causes of esophageal injury. It has been underdiagnosed and scarcely recognized in dermatology. Retrosternal pain, sudden odynophagia and a history of doxycycline or other drugs intake are some of the characteristics that lead to diagnosis. It may cause severe complications such as bleeding, stenosis and mediastinitis.

Lipschütz Ulcer: An Unusual Diagnosis that Should Not be Neglected

Abstract The diagnosis of genital ulcers remains a challenge in clinical practice. Lipschütz ulcer is a non-sexually transmitted rare and, probably, underdiagnosed condition, characterized by the sudden onset of vulvar edema along with painful necrotic ulcerations. Despite its unknown incidence, this seems to be an uncommon entity, with sparse cases reported in the literature. We report the case of an 11-year-old girl who presented at the emergency department with vulvar ulcers. She denied any sexual intercourse. The investigation excluded sexually transmitted infections, so, knowledge of different etiologies of non-venereal ulcers became essential. The differential diagnoses are extensive and include inflammatory processes, drug reactions, trauma, and malignant tumors. Lipschütz ulcer is a diagnosis of exclusion. With the presentation of this case report, the authors aim to describe the etiology, clinical course, and outcomes of this rare disease, to allow differential diagnosis of genital ulceration.

Úlcera vulvar aguda de Lipschütz / Acute vulvar ulcer of Lipschütz

RESUMEN La úlcera de Lipschütz es una entidad poco frecuente e infradiagnosticada. Se presenta el caso de una paciente de 24 años sin antecedente de contacto sexual que consultó por aparición súbita de úlceras vulvares dolorosas, en el contexto de un cuadro pseudogripal. Se discuten los principales diagnósticos diferenciales, dado que es una enfermedad no relacionada con enfermedades de transmisión sexual y poco reconocida por los profesionales de la salud, que precisa de manejo conservador.

ABSTRACT Lipschütz ulcer is a rare underdiagnosed entity. We present the case of a 24-year-old patient without history of sexual contact who consulted for sudden occurrence of painful vulvar ulcers, in the context of flu-like symptoms. The main differential diagnoses are discussed, as it is a disease unrelated to sexually transmitted diseases and little recognized by health professionals, which requires conservative management.

Indicação de oxigenioterapia hiperbárica como auxiliar na cicatrização de úlceras de membro inferiores / Indication of hyperbaric oxygen therapy as an aid in healing lower limb wounds

Esse artigo refere-se a um caso de perícia médica solicitada por motivo de ação judicial movida por paciente do sexo masculino de 49 anos de idade contra o município de Ipatinga, MG. O periciando é sabidamente portador de Doença Mista do Tecido Conjuntivo e Síndrome de Anticorpo Antifosfolípide, tendo desenvolvido, como consequência dessa última patologia, úlcera venosa crônica em membro inferior, não cicatrizada mesmo após duas cirurgias de enxertia. O paciente requer perante o juízo, por indicação de sua médica reumatologista, que o município arque com o procedimento de oxigenioterapia hiperbárica, considerando-se sua eficácia potencial na cicatrização de feridas. Deixando as considerações jurídicas do caso à parte, como médica perita do banco de peritos do Tribunal de Justiça de Minas Gerais, depois de avaliar clinicamente o paciente, realizei revisão da literatura médicocientífica no que diz respeito aos benefícios e indicações dessa forma de terapia para o mesmo. O objetivo desse artigo é descrever acerca desse procedimento médico, bem como esclarecer suas indicações e limitações, especialmente no que tange ao caso concreto apresentado. (AU)

This paper refers to a medical inquiry related to a lawsuit against Ipatinga County (MG), in which a male patient aged 49 years old requests the right to receive 60 sessions of hyberbaric oxygen therapy (HBOT), as an aid to healing wounds. The patient has been previously diagnosed with Mixed Disease of the Connective Tissue and Antiphospholipid Syndrome, having developed, as result of the latter disease, a chronic venous ulcer in the lower limb, not healed even after two grafting surgeries. Towards the Court, the patient requires the delivery of HBOT, considering its potential effectiveness in wound healing. Leaving apart the legal considerations of the case, as a medical expert of the Justice Court of Minas Gerais (TJMG), after a detailed clinical evaluation of the patient, I reviewed the medical literature regarding the benefits and indications of this form of therapy, correlating them to this concrete case. The aim of this article is to describe this relatively new medical procedure, and to clarify its indications and limitations, particularly with regard to the present case. (AU)

Avaliação para o manejo da úlcera neuropática associada à hanseníase: produção e validação de vídeo educativo / Evaluation for the management of leprosy-associated neuropathic ulcer: production and validation of educational video

A hanseníase é uma das maiores causas de complicações neuropáticas no mundo. Dentre estas, estão as úlceras neuropáticas, consideradas uma das causas mais comuns de amputações, morbidade e mortalidade, consequência de uma assistência à saúde embasada em procedimentos fragmentados com baixa resolutividade. Estudo de delineamento metodológico, com abordagem quali-quantitativa dos dados, que objetivou desenvolver um vídeo para intervenção educativa sobre avaliação para manejo da úlcera neuropática associada à hanseníase, a ser disponibilizado a enfermeiros. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa e foi realizada em 4 etapas: 1: Produção do roteiro e storyboard; 2:Validação do roteiro e storyboard; 3: Edição do vídeo e 4: Estudo piloto. A produção do conteúdo do roteiro e storyboard seguiu as recomendações do Ministério da Saúde e da Wound, Ostomy and Continence Nurses. A validação de conteúdo e aparência foi realizada por um comitê de especialistas. O instrumento apresentou os seguintes quesitos: objetivo; conteúdo; relevância; ambiente; funcionalidade, usabilidade e eficiência, os quais foram considerados validados a partir da concordância de 78% entre os avaliadores, calculada por meio do Índice de Validade de Conteúdo. Entre os especialistas na temática, houve maior prevalência do sexo feminino (88,9%), com idade entre 29 e 62 anos (média de 42,3 anos e desvio padrão de 11,0 anos), sendo a maior titulação acadêmica o doutorado (55,6%), e tempo de atuação profissional entre seis e 30 anos (média de 14,9 anos e desvio padrão de 8,2 anos). Dos especialistas em vídeo, a maioria era do sexo feminino (62,5%), com idade entre 30 e 46 anos (média de 37,5 anos e desvio padrão de 6,4 anos), com maior número de mestres (50%) e tempo de atuação profissional entre 2 e 24 anos (média de 10,8 anos e desvio padrão de 7,3 anos). Para todos os quesitos avaliados, obteve-se um Índice de Validade de Conteúdo superior ao mínimo preconizado. Após a adequação do roteiro e storyboard em face da validação, o vídeo foi gravado e, a partir de uma préedição, um estudo piloto (validação semântica) foi realizado por meio da técnica de grupo focal, com a participação de nove enfermeiros que atuavam na assistência à pessoa com hanseníase. Houve prevalência do sexo feminino (88,9%), com idade entre 29 e 50 anos e maior titulação acadêmica em nível de mestrado (55,6%), sendo que a maioria (55,6%) atuava na Estratégia Saúde da Família. A partir da análise de conteúdo do grupo focal, emergiram as categorias: dialogar sobre os objetivos propostos; identificar a aplicabilidade do vídeo na prática clínica do enfermeiro e valorizar a consulta de enfermagem na avaliação de pessoas com úlcera neuropática associada à hanseníase. Acredita-se que o vídeo educativo validado poderá auxiliar na realização de uma avaliação de enfermagem eficaz, segura e com qualidade à pessoa com úlcera neuropática decorrente da hanseníase

Leprosy is one of the major causes of neuropathic complications in the world. Among the complications most commonly found are neuropathic ulcers, considered one of the most common causes of amputations, morbidity and mortality in the world, as a consequence of health care based on fragmented procedures with low resolution. This is a methodological design study with qualitative and quantitative data, aiming to develop a video for educational intervention on evaluation for the management of neuropathic ulcer associated with leprosy, to be made available to nurses. The research was approved by the Research Ethics Committee and was carried out in 4 stages: 1: Production of the script and storyboard; 2: Script and storyboard validation; 3: Video editing and 4: Pilot study. The production of script content and storyboard followed the recommendations of the Ministry of Health and Wound, Ostomy and Continence Nurses. Validation of content and appearance was performed by a committee of experts. The instrument presented the following requirements: objective; content; relevance; environment; functionality, usability and efficiency, which were considered validated from the agreement of 78% between the evaluators, calculated through the Content Validity Index Among the specialists in the subject, there was a higher prevalence of female (88.9%), aged between 29 and 62 years (mean of 42.3 years and standard deviation of 11.0 years), the highest academic qualification being the doctoral degree (55.6%), and professional performance time between six and 30 years (mean of 14.9 years and standard deviation of 8.2 years). Of the video specialists, the majority were female (62.5%), aged between 30 and 46 years (mean of 37.5 years and standard deviation of 6.4 years), with a greater number of masters (50%) and time of professional activity between 2 and 24 years (mean of 10.8 years and standard deviation of 7.3 years). For all evaluated items, a Content Validity Index higher than the recommended minimum was obtained. After the adaptation of the script and storyboard in the face of validation, the video was recorded and, from a pre-edition, a pilot study (semantic validation) was performed through the focal group technique, with the participation of nine nurses who assisted the person with leprosy. There was a prevalence of females (88.9%), aged between 29 and 50 years, and a higher academic degree at the master's level (55.6%), with the majority (55.6%) working in the Family Health Strategy. From the content analysis of the focus group, the following categories emerged: dialogue about the proposed objectives; to identify the applicability of the video in the clinical practice of the nurse and to value the nursing consultation in the evaluation of people with neuropathic ulcer associated with leprosy. It is believed that the validated educational video can help in the performance of an effective, safe and quality nursing assessment to the person with neuropathic ulcer due to leprosy

Tratamiento quirúrgico curativo combinado con Heberprot-P® en las úlceras neuropáticas del antepié / Combination of the curative surgical treatment and Heberprot-P® in the neuropathic ulceration of the forefoot

Introducción: la cirugía curativa se realiza en un pie diabético con lesiones y pérdida de la sensación protectora para lograr su cicatrización. En la literatura disponible no se encontraron estudios prospectivos que avalen sus resultados cuando se aplica combinada con el Heberprot-P®. Objetivos: examinar los resultados de la cirugía curativa combinada con el Heberprot-P® en las úlceras neuropáticas del antepié. Métodos: se realizó un estudio de serie de casos en el Servicio Provincial de Angiología de Matanzas, en un período de tres años y cuatro meses. Se incluyeron pacientes diabéticos de ambos sexos que aportaron 123 extremidades con úlceras neuropáticas del antepié y que recibieron como tratamiento para las lesiones cirugía curativa y terapia adyuvante con Heberprot-P®. Resultados: las lesiones tratadas eran de gradación Wagner 2 (56,1 por ciento) y 3 (43,9 por ciento). La evaluación de la infección aportó el grado 1 (52,8 por ciento) y el grado 2 (47,2 por ciento). El tiempo de epitelización fue menor en los pacientes tratados con cirugía curativa combinada con Heberprot-P® en relación con los que no utilizaron este último. El comportamiento de las recidivas fue similar. Conclusiones: la combinación de la cirugía curativa y el Heberprot-P® en pacientes diabéticos con úlceras neuropáticas del antepié, reduce el tiempo de epitelización y de recidivas(AU)

Introduction: curative surgery is performed to reach healing of a diabetic foot with injures and loss of protective sensations. The available literature did not show prospective studies that supported the results attained with this surgery when applied with Heberprot-P®. Objectives: to analyze the results of the combination of curative surgery and Heberprot-P® to treat neuropathic ulcers of the forefront. Methods: a case series study was conducted in the provincial service of angiology in Matanzas for three years and four months, with the inclusion of 123 lower limbs with neuropathic wounds in the forefoot, which were treated with curative surgery and adjuvant Heberprot-P® therapy. Results: the treated wounds were classified as Wagner 2 (56.1 percent) and 3 (43.9 percent). The infection evaluation yielded grade 1 (52.8 percent) and grade 2 (47.2 percent). Time of epithelization exhibits a significant reduction in the patients treated with curative surgery and adjuvant therapy with Heberprot-P®, in comparison with those untreated cases. The behavior of relapses was similar in both cases. Conclusions: the association of curative surgery and Heberprot-P® used in diabetic patients with neuropathic wounds of the forefoot, reduces the time of epithelization and of relapses(AU)

Uso del factor de crecimiento epidérmico recombinante humano (EGF), en úlceras de pie diabético / Use of Epidermal Growth Factor Recombinant Human (EGF), in diabetic foot ulcers

El pie diabético es una de las complicaciones frecuentes de la Diabetes Mellitus 2 mal controlada, se reporta una incidencia entre el 15 y el 30 % de ulceras en el paciente diabético durante su enfermedad, con un alto costo económico y social, debido a la prolongada estadía hospitalaria y a la alta tasa de amputaciones, que dificultan la reincorporación del paciente a la sociedad. Teniendo en cuenta la capacidad reparadora del factor de crecimiento epidérmico (EGF) el cual favorece el proceso de cicatrización al acelerar la regeneración epidérmica, se realiza un estudio observacional, retrospectivo en 300 pacientes tratados con EFG intradérmico, perilesional , dos veces a la semana hasta la granulación y/o completa cicatrización. Se logró cicatrización en un promedio de ocho semanas de tratamiento en un 40% de la población, un 30% no cicatrizo, 20% abandonaron el tratamiento debido a reacciones adversas tales como fiebre, escalofríos, dolor, y un 10% ameritó amputación. Se concluye, que el tratamiento de elección del pie diabético es la prevención, pero el EGF intradérmico perilesional es una opción terapéutica efectiva para los pacientes con ulcera de pie diabético grado 1 al 4 de Wagner(AU)

The diabetic foot is one of the common complications of poorly controlled diabetes mellitus 2, an incidence between 15 and 30% of ulcers in diabetic patients during their illness is reported, with high economic and social costs due to prolonged hospital stay and the high rate of amputations, which hinder the reintegration of the patient into society. Considering the repair capacity of epidermal growth factor (EGF) which promotes the healing process to accelerate epidermal regeneration, an observational retrospective study was performed on 300 patients treated with intradermal perilesional EFG, twice a week until granulation and / or complete healing. Healing was achieved in an average of eight weeks of treatment in 40% of the population, 30% not healed, 20% discontinued treatment due to adverse reactions such as fever, chills, pain, and 10% required amputation. It is concluded that the treatment of choice for diabetic foot is prevention, but the perilesional intradermal EGF is an effective therapeutic option for patients with diabetic foot ulcer grade 1 to 4 of Wagner(AU)

Genital ulcer development in patients with acute promyelocytic leukaemia treated with all-trans retinoic acid: a case series

We report here four cases of genital ulcers that developed after the administration of all-trans retinoic acid [ATRA] for the treatment of acute promyelocytic leukemia [APL]. Between October 2007 and March 2010, three males and one female [age range 19-35 years] were identified to have genital ulcers after being prescribed all-trans retinoic acid [ATRA] as a part of chemotherapy for APL. This is the first series of cases describing genital ulcers, as a unique and rare complication of ATRA used for treatment of APL in these patients, with no other cause identified. Following temporary cessation of ATRA for a few days in these three cases, improvement of the ulcers was noted

Unilateral conjunctival ulcer due to Stenotrophomonas maltophilia infection.

We report a case of unilateral conjunctival ulcer due to Stenotrophomonas maltophilia infection in an immunocompetent individual. A 44-year-old male presented with complaints of pain and yellowish discharge in the right eye for one week. Patient underwent complete ophthalmic evaluation and relevant laboratory investigations. Anterior segment examination revealed localized conjunctival and episcleral congestion with conjunctival ulceration on the bulbar conjunctiva in the right eye. Gram's stain revealed gram-negative bacilli. Culture and sensitivity revealed S. maltophilia and responded well to topical moxifloxacin with systemic co-trimoxazole therapy.

Úlcera solitaria de recto / Solitary rectal ulcer

Introducción: La úlcera solitaria de recto es una entidad patológica crónica, benigna e infrecuente, que en general no se la considera entre los diagnósticos diferenciales de las patologías crónicas del recto. A menudo es subdiagnosticada. Las principales manifestaciones clinicas son: proctorragia, mucorrea, esfuerzo defecatorio y tenesmo. Objetivo: Evaluar las características clinicas de una patología infrecuente del recto, a partir de 3 casos clínicos. Lugar de aplicación: Institución privada. Pacientes y método: Se presentan 3 pacientes con diagnóstico anatomopatológico de úlcera solitaria de recto, entre 2003-2010, dos hombres y una mujer, con un promedio de edad de 53 años (rango 41-70 años). Resultados: La presentación clínica fue proctorragia, mucorrea, tenesmo, proctalgía y esfuerzo defecatorio. En los 3 pacientes la úlcera fue solitaria, dos en pared posterior y una en pared anterior del recto. El diagnostico se realizó por medio de la endoscopía, y biopsia de la lesión. Los 3 casos respondieron favorablemente al tratamiento médico. Conclusiones: La etiología es desconocida. Se la relaciona con trastornos de la defecación. La lesión no siempre es ulcerada ni solitaria. El diagnóstico se realiza por medio de colonoscopía y biopsia, debido a que presenta histología patognomónica. El tratamiento puede ser conservador o quirúrgico.

Introduction: Solitary rectal ulcer is a chronic, benign and infrequent entity, generally not considered in the differential diagnosis of chronic diseases of the rectum. It is often under­diagnosed. The main clinical manifestations include bloody stool, mucorrhea, straining and tenesmus. Objective: To asses the current behavior of a rare disease of the rectum, from 3 clinical cases. Point of application: Private institution. Patients and method: Three patients are presented with pathological diagnosis of solitary rectal ulcer, between 2003 - ­2010, two men and a woman, with an average age of 53 years (range 41-70 years). Results: The clinical presentation was bloody stool, mucorrhea. tenesmus, anal pain and straining. In all cases the ulcer was solitary; two in posterior wall and one in anterior wall of the rectum. The diagnosis was made by endoscopy and biopsy of the lesion. The 3 cases responded well to medical treatment. Conclusions: The etiology is unknown. It is related to defecation disorders. The lesion is not always ulcerated of solitary. Diagnosis is made by colonoscopy and biopsy, because it shows pathognomonic histology. Treatment can be conservative or surgical.

Enteritis ulcerativa estenosante multifocal criptogénica (CMUSE) diagnosticada por enteroscopia doble balón: ¿una forma de vasculitis intestinal? / Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) diagnosed by double balloon enteroscopy: a type of intestinal vasculitis?

Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare pathology with no more than 30 reported cases worldwide. The diagnosis requires a combination of clinical elements, imagenological and histological, and to rule out other pathologies. This is the case of a 36 year-old patient presenting anemia, abdominal pain and diarrhea related to immune manifestations with a CMUSE diagnosis. Double balloon enteroscopy was a critical tool for the diagnosis. The patient showed a good response to steroidal treatment with symptomatic remission.

La enteritis estenosante y ulcerativa multifocal idiopática (CMUSE) es una entidad poco frecuente con no más de 30 casos reportados a nivel mundial. El diagnóstico requiere una combinación de elementos clínicos, imagenológicos e histológicos, y descartar otras patologías. Presentamos el caso de una paciente de 36 años que se presenta con anemia, dolor abdominal y diarrea asociado a manifestaciones inmunológicas con diagnóstico de CMUSE. La enteroscopia Doble Balón fue una herramienta fundamental para el diagnóstico. Evolucionó con buena respuesta a tratamiento esteroidal con remisión sintomática mantenida.

Stress modulating antioxidant effect of Nardostachys jatamansi.

The rhizomes of Nardostachysjatamansi, the plant commonly known as Jatamansi have been described in Ayurveda for their soothing and sedative action on the central nervous system. In the present study, the anti-stress effect of hydroethanolic extract (70%) of N. jatamansi (NJE) was evaluated in reference to its antioxidant property. Wistar rats were divided into four groups: naive, stressed, and T-200 and T-500 stressed with oral pre-treatment of NJE 200 and 500 mg/kg, respectively. Restraint of rats in metallic chambers for 4 h at 4 degreesC was followed by sacrifice and assessment of stress-induced alterations in biochemical parameters, incidence and severity of ulcers. Lipid peroxidation (LPO) and NO levels in stomach and LPO, NO levels and catalase activity in brain, plasma corticosterone level and adrenal ascorbic acid were measured. In vitro antioxidant activity of NJE was studied by measuring the free radical scavenging activity. NJE showed potent antioxidant activity and significantly reversed the stress-induced elevation of LPO and NO levels and decrease in catalase activity in the brain. It inhibited the incidence of gastric ulcerations and reversed the alterations in biochemical parameters/markers of stress-induced gastric ulceration. NJE also significantly altered stress-induced increase in adrenal and spleen weights and decrease in level of ascorbic acid in adrenal gland. Elevation of plasma corticosterone level was negated dose- dependently. The findings suggest that the NJE possesses significant anti-stress activity, which may be due to its antioxidant activity.

The Effect of Proton Pump Inhibitor on Healing of Post-esophageal Variceal Ligation Ulcers / 대한소화기학회지

BACKGROUNE/AIMS: Esophageal variceal ligation (EVL) is the most preferable method for controling variceal bleeding. However, EVL is associated with complications such as hemorrhage, chest pain, dysphagia, and odynophagia due to post-EVL ulcers in the esophageal mucosa. The aim of this study was to assess the effect of proton pump inhibitor (PPI), pantoprazole on the healing of post-EVL ulcers. METHODS: Forty seven patients were randomly allocated into PPI group and control group. Patients in PPI group received 40 mg of pantoprazole intravenously for 3 days after EVL, then 40 mg of oral pantoprazole for 11 days consecutively. Control patients received intravenous and oral placebo. Endoscopic examinations were performed twice at 7+/-2 days and 14+/-2 days after EVL respectively. Clinical outcomes include the size of ulcers, symptoms reported by patients; chest pain, dysphagia, and odynophagia. RESULTS: Forty seven patients completed the 7 days protocol (PPI/control; 25/22), and twenty six patients completed the 14 days protocol (PPI/control; 16/10). Post-EVL ulcers in PPI group were significantly smaller than those in control group (7 days; 98.7 mm2/119.4 mm2, 14 days; 32.3 mm2/43.8 mm2, p0.05). Nineteen patients (PPI/control; 9/10) did not complete the 14 days protocol due to patients' refusal and adverse outcomes, such as hepatic failure and sepsis with bleeding from post-EVL ulcer occurred in two patients of control group. CONCLUSIONS: PPI treatment following EVL may be effective in healing post-EVL ulcer.

A Case of Terminal Ileal Ulcer of Henoch-Sch?nlein Purpura Treated with High Dose Steroid / 대한소화기학회지

Henoch-Schonlein purpura (H-S purpura) is a systemic small-vessel vasculitis involving skin, joint, gastrointestinal tract, and kidney. It is characterized by the classic tetrad of abdominal pain, arthralgia, typical rash, and renal involvement. All of these clinical findings can occur in any order and at any time over several days to weeks. Gastrointestinal manifestations such as abdominal pain, melena, or hematochezia occur in 45-85% and preceed skin lesions upto 40% in H-S purpura. However, endoscopically proven gastrointestinal lesion is rare because majority of involved sites are small intestine. We report a case of Henoch-Schonlein purpura with terminal ileal ulcer, healed after treatment with high dose steroid, proven by colonoscopy.

Amoebiasis cutis in HIV positive patient.

Protozoan infections of the skin, particularly cutaneous amoebiasis, are rare in HIV-positive patients. We report a case of amoebiasis cutis in an HIV-positive truck driver with a history of frequent unprotected sexual exposures. He presented with multiple painful ulcers and sinuses with purulent discharge, necrotic slough and scarring in the perianal and gluteal region for the last 2 years. He was positive for HIV-1 and -2. Cutaneous biopsy revealed numerous Entamoeba histolytica in the trophozoite form, in addition to an inflammatory infiltrate and necrotic debris. He responded well to oral metronidazole and chloroquine. Amoebiasis cutis should be considered in the differential diagnosis of perianal ulcers, particularly in HIV-positive patients.

Liquen plano: reporte de un caso / Lichen planus: report a case

El liquen plano es una enfermedad de la piel, sus anexos y mucosas de carácter inflamatoria, y aunque por lo general se presta como pápulas pruriginosas puede estar conformada por otras lesiones primarias ya sean placas, vesículas o ampollas. Tiene una amplia variedad clínica. Su etiología es desconocida aunque existen varias teorías. Se presenta a continuación el caso de un paciente de 54 años, conocido sano, quien consultó por un cuadro de aproximadamente 3 años de evolución de lesiones en piel localizadas en piernas y brazos caracterizado por placas de color púrpura violácea de superficie plana, con escamas gruesas hiperqueratósicas puriginosas a quién se realiza biopsia de piel que evidenció hallazgos típicos de liquen plano. En este artículo se hace una revisión del liquen plano y sus variaciones clínicas.

Effect of standardized extract of Ocimum sanctum Linn. on gastric mucosal offensive and defensive factors.

The standardized methanolic extract of leaves of O. sanctum (OSE; eugenol content 5%) given in doses of 50-200 mg/kg, orally, twice daily for five days showed dose-dependent ulcer protective effect against cold restraint stress induced gastric ulcers. Optimal effective dose (100 mg/kg) of OSE showed significant ulcer protection against ethanol and pyloric ligation-induced gastric ulcers, but was ineffective against aspirin-induced ulcers. OSE significantly healed ulcers induced by 50% acetic acid after 5 and 10 days treatment OSE (100 mg/kg) significantly inhibited the offensive acid-pepsin secretion and lipid peroxidation and increased the gastric defensive factors like mucin secretion, cellular mucus, and life span of mucosal cells and had antioxidant effect, but did not induce mucosal cell proliferation. The results indicate that the ulcer protective and healing effects of OSE may be due to its effects both on offensive and defensive mucosal factors.
