The great mimicker: A case report of an extensive pyoderma gangrenosum in a 39-year-old Filipino female treated with systemic corticosteroids and antibiotics

Introduction@#Pyoderma gangrenosum (PG) is a rare inflammatory disease with unknown etiology. Ulcerative PG presents with a rapidly enlarging painful ulcer with erythematous and undermined border often misdiagnosed as infection, vascular disorder, malignancy, and other inflammatory disease. Hence, this poses a diagnostic challenge for clinicians leading to a delay in the management and significant morbidity. The treatment of PG is equally challenging due to the rarity of the disease and the scarcity of clinical trials. Currently, there are no clinical practice guidelines for the management of PG. @*Case Report@#Our patient presented with multiple large ulcers with erythematous and undermined borders over the chest, abdomen, and the lower back. Cribriform scars and contractures were noted as well. She underwent several sessions of surgical debridement and was given different broad-spectrum antibiotics with noted worsening of the lesions. Due to extensive involvement of the disease, her quality of life has been significantly affected. A diagnosis of PG was made after the biopsy showed predominantly neutrophilic infiltrate. Prednisone 1mg/kg/day and clobetasol propionate ointment were initiated with significant decrease in pain and size of the ulcers after one month of therapy. Doxycycline was used as an adjunct therapy with excellent response.@*Conclusion@#Pyoderma gangrenosum is a rare, debilitating disease that remains a diagnostic dilemma. The worsening of ulcers despite surgical debridement and antibiotics is a clue that should prompt clinicians to consider PG. This case highlights the important role of dermatology in individuals who present with non-healing chronic ulcers because as seen in this case, not all ulcers are just ulcers.

Design and application of a kind of anti-bedsore turning pad / 中华危重病急救医学

Patients who are bedridden are for a long-time prone to develop bedsores, especially in the hip and sacral areas and limbs, which causes eczema, ulcers, infection and other complications, resulting in pain and more medical costs. Therefore, the medical staff of the Second Affiliated Hospital of Zunyi Medical University designed and developed a kind of anti-bedsore turning pad, and has obtained the national utility model patent (ZL 2021 2 3004923.9), which is suitable for various long-term bedridden patients. The anti-bedsore turning pad includes the center axis of the turning pad, and ventilation pad 1 and ventilation pad 2 designed on the left and right of turning pad center axis. Under the ventilation pad 1 and the ventilation pad 2, the air pad 1 and the air pad 2 are respectively designed. There is a bedspread connected with ventilation pad 1 and ventilation pad 2 on the inflatable pad 1 and the inflatable pad 2. Through the design of inflatable pad 1 and inflatable pad 2, the left and right of the anti-bedsore turning pad can be lowered or raised independently, which is convenient for the patient's body to tilt and turn over, and can significantly reduce the number of nursing staff and the burden of nursing staff when turning over. In addition, it is convenient to replace the force site at any time and reduce the occurrence of pressure ulcers caused by long-term pressure on the force site. Through the design of ventilation cushion 1 and ventilation cushion 2, the internal gas flow of the turning pad can be made, and the ventilation between the patient and the turning pad can be kept dry, so as to reduce the occurrence of eczema, ulcers or infection and other complications, and ultimately reduce the occurrence of bedsores. In addition, through the design of the most superficial limb pad, the patient's limb can be appropriately elevated or massaged, which increases the comfort of the patient. The anti-bedsore turning pad is simple and effective, and can be widely used in long-term bedridden patients.

Study on quantitative analysis of bracket-induced nonlinear response of labio-cheek soft tissue during the orthodontic process / 生物医学工程学杂志

In the orthodontics process, intervention and sliding of an orthodontic bracket during the orthodontic process can arise large response of the labio-cheek soft tissue. Soft tissue damage and ulcers frequently happen at the early stage of orthodontic treatment. In the field of orthodontic medicine, qualitative analysis is always carried out through statistics of clinical cases, while quantitative explanation of bio-mechanical mechanism is lacking. For this purpose, finite element analysis of a three-dimensional labio-cheek-bracket-tooth model is conducted to quantify the bracket-induced mechanical response of the labio-cheek soft tissue, which involves complex coupling of contact nonlinearity, material nonlinearity and geometric nonlinearity. Firstly, based on the biological composition characteristics of labio-cheek, a second-order Ogden model is optimally selected to describe the adipose-like material of the labio-cheek soft tissue. Secondly, according to the characteristics of oral activity, a two-stage simulation model of bracket intervention and orthogonal sliding is established, and the key contact parameters are optimally set. Finally, the two-level analysis method of overall model and submodel is used to achieve efficient solution of high-precision strains in submodels based on the displacement boundary obtained from the overall model calculation. Calculation results with four typical tooth morphologies during orthodontic treatment show that: ① the maximum strain of soft tissue is distributed along the sharp edges of the bracket, consistent with the clinically observed profile of soft tissue deformation; ② the maximum strain of soft tissue is reduced as the teeth align, consistent with the clinical manifestation of common damage and ulcers at the beginning of orthodontic treatment and reduced patient discomfort at the end of treatment. The method in this paper can provide reference for relevant quantitative analysis studies in the field of orthodontic medical treatment at home and abroad, and further benefit to the product development analysis of new orthodontic devices.

Research advances in role of angiogenesis in diabetic ulcer and traditional Chinese medicine intervention / 中国中药杂志

Diabetic ulcer(DU) is one of the common complications of diabetes often occurring in the peripheral blood vessels of lower limbs or feet with a certain degree of damage. It has high morbidity and mortality, a long treatment cycle, and high cost. DU is often clinically manifested as skin ulcers or infections in the lower limbs or feet. In severe cases, it can ulcerate to the surface of tendons, bones or joint capsules, and even bone marrow. Without timely and correct treatment, most of the patients will have ulceration and blackening of the extremities. These patients will not be able to preserve the affected limbs through conservative treatment, and amputation must be performed. The etiology and pathogenesis of DU patients with the above condition are complex, which involves blood circulation interruption of DU wound, poor nutrition supply, and failure in discharge of metabolic waste. Relevant studies have also confirmed that promoting DU wound angiogenesis and restoring blood supply can effectively delay the occurrence and development of wound ulcers and provide nutritional support for wound healing, which is of great significance in the treatment of DU. There are many factors related to angiogenesis, including pro-angiogenic factors and anti-angiogenic factors. The dynamic balance between them plays a key role in angiogenesis. Meanwhile, previous studies have also confirmed that traditional Chinese medicine can enhance pro-angiogenic factors and down-regulate anti-angiogenic factors to promote angiogenesis. In addition, many experts and scholars have proposed that traditional Chinese medicine regulation of DU wound angiogenesis in the treatment of DU has broad prospects. Therefore, by consulting a large number of studies available, this paper expounded on the role of angiogenesis in DU wound and summarized the research advance in traditional Chinese medicine intervention in promoting the expression of angiogenic factors [vascular endothelial growth factor(VEGF), fibroblast growth factor(FGF), and angiopoietin(Ang)] which played a major role in promoting wound angiogenesis in the treatment of DU to provide ideas for further research and new methods for clinical treatment of DU.

Research progress in role of autophagy in diabetic wound healing and traditional Chinese medicine intervention / 中国中药杂志

Diabetic ulcer(DU) is a chronic and refractory ulcer which often occurs in the foot or lower limbs. It is a diabetic complication with high morbidity and mortality. The pathogenesis of DU is complex, and the therapies(such as debridement, flap transplantation, and application of antibiotics) are also complex and have long cycles. DU patients suffer from great economic and psychological pressure while enduring pain. Therefore, it is particularly important to promote rapid wound healing, reduce disability and mortality, protect limb function, and improve the quality of life of DU patients. By reviewing the relevant literatures, we have found that autophagy can remove DU wound pathogens, reduce wound inflammation, and accelerate ulcer wound healing and tissue repair. The main autophagy-related factors microtubule-binding light chain protein 3(LC3), autophagy-specific gene Beclin-1, and ubiquitin-binding protein p62 mediate autophagy. The traditional Chinese medicine(TCM) treatment of DU mitigates clinical symptoms, accelerates ulcer wound healing, reduces ulcer recurrence, and delays further deterioration of DU. Furthermore, under the guidance of syndrome differentiation and treatment and the overall concept, TCM treatment harmonizes yin and yang, ameliorates TCM syndrome, and treats underlying diseases, thereby curing DU from the root. Therefore, this article reviews the role of autophagy and major related factors LC3, Beclin-1, and p62 in the healing of DU wounds and the intervention of TCM, aiming to provide reference for the clinical treatment of DU wounds and subsequent in-depth studies.

Gastroprotective potential and mechanisms of action of Hedera nepalensis

Abstract Hedera nepalensis (H. nepalensis) , belonging to the family Araliaceae, is a medicinal plant traditionally used to treat stomach problems. The current study investigated the gastroprotective potential and the mechanism of action of H. nepalensis in diclofenac-and ethanol-induced ulcer models. Anti-oxidant and lipid peroxidation inhibitory prospects of H. nepalensis were checked out by free radical scavenging assay and UV spectrophotometer respectively. Effect of H. nepalensis on the pH, gastric total acidity of gastric juice and protective effects of H. nepalensis against ulcer models have been examined. Histopathological studies have been carried out. The aqueous methanol extract of H. nepalensis (100 µg/mL) showed anti-oxidant (83.55%) and lipid peroxidation inhibitory (70.88%) potential at 1000 µg/mL; the extract had no buffer potential. The extract (400 mg/kg) significantly (81.12% and 63.46%) showed gastroprotective effect in diclofenac and ethanol-induced rat ulcer models respectively. Histopathological studies confirmed the biochemical findings. FTIR analysis showed the presence of carboxylic acid, alkanes, conjugated alkanes, aldehydes and alkyl-aryl ethers. Gallic acid, M-coumaric acid and quercetin were found by HPLC analysis. H. nepalensis exhibited significant protection against diclofenac and ethanol induced gastric damage by anti-oxidant and lipid peroxidation suppression effects suggesting potential broad utility in treatment of diseases characterized with gastric damage.

Presencia de dientes natales o neonatales en pacientes pediátricos con y sin labio y paladar hendido / Presence of natal or neonatal teeth in pediatric patients with and without cleft lip and palate

Objetivo: determinar la presencia de dientes natales y neonatales en pacientes pediátricos con/sin labio y paladar hendido, que han sido atendidos en un hospital de tercer nivel de 2019-2020, mediante la revisión de expedientes clínicos. Métodos: estudio retrospectivo, observacional descriptivo y revisión de expedientes de pacientes atendidos de 2019-2020. Resultados: en el hospital de tercer nivel se reportan 15 nacimientos por día, 5475 al año. De estos, se identificaron 110 bebés con dientes natales revisados en cuneros, 84 pacientes con labio y paladar hendido en consulta, con una relación de 1:50, mayor prevalencia en dientes inferiores centrales. Su manejo fue resuelto con extracciones en todos los casos, debido a la movilidad dental y el riesgo potencial en la alimentación por bronco aspiración del paciente. Conclusiones: los dientes neonatales y natales se encontraron con mayor frecuencia en pacientes de unidades de tercer nivel consultadas, posiblemente por ser centros de referencia. Se identificó confusión en el personal de salud respecto a la nomenclatura de los dientes que presentan los pacientes al nacer (dientes neonatales), además, se encontró una alta frecuencia de dientes natales en los pacientes estudiados en este caso. La relevancia se encuentra en que no hay estudios que definan la razón del porqué los pacientes nacen con dientes. La respuesta puede estar relacionada con un factor hormonal de la madre, aunque no se ha encontrado evidencia sobre esto. Mientras que los dientes neonatales

Objective: To determine the presence of natal and neonatal teeth in pediatric patients with/without cleft lip and palate who have been seen in a tertiary hospital from 2019-2020, by reviewing clinical records. Methods: Retrospective, descriptive observational study and review of patient records from 2019-2020. Results: In the third level hospital 15 births are reported per day, 5475 per year. Of these, 110 babies with natal teeth were identified in the nursery, 84 patients with cleft lip and palate were identified in consultation, with a ratio of 1:50, with a higher prevalence in lower central teeth. Their management was solved with extractions in all cases, due to tooth mobility and the potential risk in feeding by bronchial aspiration of the patient. Conclusions: Neonatal and natal teeth were found more frequently in patients in the tertiary level units consulted, possibly because they were referral centers. Confusion was identified among health personnel regarding the nomenclature of the teeth that patients present at birth (neonatal teeth), and a high frequency of natal teeth was found in the patients studied in this case. The relevance lies in the fact that there are no studies that define the reason why patients are born with teeth. The answer may be related to a hormonal factor of the mother, although no evidence on this has been found. While neonatal teeth occurred less frequently, there are no conclusive studies either.

Manejo de hemangioma ulcerado segmentario: combinación de tratamiento sistémico y tópico en dos casos pediátricos / Management of ulcers on a segmental hemangioma: A combination of systemic and topical therapies in two pediatric cases

Los hemangiomas infantiles (HI) son los tumores benignos más frecuentes de la infancia; la variante segmentaria es rara y se asocia con un mal pronóstico. Una de sus principales complicaciones es la ulceración durante la fase de crecimiento del tumor, a pesar de no presentar características macroscópicas compatibles con una lesión agresiva. El manejo en estos casos es dificultoso e impone la necesidad de asociar múltiples estrategias, algunas orientadas específicamente a impedir la proliferación del hemangioma y otras orientadas a la curación de la herida, el manejo del dolor y la prevención de la infección agregada. Presentamos dos casos a fin de comunicar nuestra experiencia respecto del manejo de dicha patología y su evolución final.

Infantile hemangiomas (IHs) are the most common benign tumors of childhood, and segmental ones are rare and associated with a poor prognosis. While these tumors look harmless, one of their main related complications is ulceration during tumor growth. The management in these cases is extremely challenging, requiring a combination of multiple approaches, some specifically aimed at preventing the proliferation of the hemangioma and others aimed at wound care, pain management, and prevention of further infection. Here we discuss two cases to narrate our experience on the management of this condition and its outcome.

Determinación de Helicobacter spp. en mucosa gástrica glandular de muías a través de la prueba de la actividad de la ureasa e histopatología / Determination of Helicobacter spp. in glandular gastric mucosa of mules through the test of urease activity and histopathology

RESUMEN La información sobre la presentación y los factores predisponentes del síndrome de úlcera gástrica en mulas (SUGM) es escasa en comparación con el síndrome de úlcera gástrica en equinos (SUGE) y asnales. Debido a la naturaleza multifactorial de este síndrome, la helicobacteriosis ha sido estudiada en otras especies. El objetivo de este trabajo fue establecer la presencia de Helicobacter spp. en mucosa gástrica de mulas a través de la prueba rápida de la ureasa (PRU) y de análisis histopatológico. Menos del 27% de las muestras reaccionaron a la PRU, con tiempos prolongados de reacción, y al Agar Urea (prueba de oro), con menor porcentaje de positividad. La histopatología reveló procesos inflamatorios crónicos, sin presencia de bacterias curvoespiraladas. Las PRU no fueron conclusivas en la determinación de Helicobacter spp., comportamiento similar reportado en equinos. Se requieren exámenes diagnósticos más específicos y procedimientos complementarios orientados a explorar por regiones del estómago en la consideración del número de muestras representativas.

ABSTRACT Information on the presentation and predisposing factors of Mule Gastric Ulcer Syndrome (MGUS) is scarce, compared to Equine Gastric Ulcer Syndrome (EGUS) and donkeys. Within the multifactorial nature of this syndrome, helicobacteriosis has been studied in other species. The objective of this work was to establish the presence of Helicobacter spp. in gastric mucosa of mules, through the rapid urease test (RUT) and histopathological analysis. Less than 27% of the samples reacted to RUTs, with prolonged reaction times, and Urea Agar (gold test), with a lower percentage of positivity. Histopathology revealed chronic inflammatory processes, without the presence of curved-spiral bacteria. The RUTs were not conclusive in the determination of Helicobacter spp., a similar behavior reported in horses. More specific diagnostic tests and complementary procedures are required to explore the regions of the stomach in consideration of the number of representative samples.

Introduction: Venous ulcers are lesions developed mainly on the lower limbs. They cause continuous and disabling pain, impair mobility, alter self-image, and interfere with daily life activities. Venous ulcers are serious. They are caused by chronic venous insufficiency and permanent venous hypertension. People suffering from venous ulcers should receive comprehensive nursing care that contributes to self-care. Objective: To describe the strategies nursing professionals should consider for promoting self-care in people with venous ulcers. Method: Integrative review of the literature. Databases and electronic resources were searched: Medline using PubMed, Health, Epistemonikos, and SciELO. Research and review articles related to the study problem, published in English, Portuguese, or Spanish between 2010 and 2020, were included. This is a risk-free study, and copyrights were respected. Results: A sample of 41 publications was analyzed. The main themes derived from the analysis were the nursing care process and self-care, getting familiar with venous ulcers and therapeutic options, knowledge of compression therapy, and practice of healthy lifestyles. Conclusions: Nursing care for patients with venous ulcers should begin by recognizing a person from a holistic perspective and reciprocally with their environment. This approach implies a comprehensive care process that goes beyond the ulcer and values patients as active subjects of care so that they become familiar with their wounds and detect signs of improvement or warning. They can also know about compression therapy and therapeutic options and take the practice of healthy lifestyles into their daily lives.

The value of terminal lleum intubation during colonoscopy

Abstract It is uncertain whether terminal ileum intubation should be performed routinely during colonoscopy, as there is uncertainty regarding its diagnostic value. The aim of the present study is to assess the diagnostic yield of terminal ileum intubation during colonoscopy according to indications for colonoscopy. This is a cross-sectional study in which the results of 294 total colonoscopy procedures were reviewed; ileal intubation was performed in 269 (91.49%) patients. The indications for colonoscopy, the results of ileoscopy, and the histopathological results of ileal biopsies were evaluated. A total of 54 (20%) out of 269 patients who had successful intubation into the terminal ileumshowed macroscopic abnormalities on the terminal ileum. Biopsies were positive in 4 out of 54 (7.4%); all were of Crohn disease. Two were erosions (9.5%.) and 2 were ulcers (18.8%). The two erosions were presented as abdominal pain, abdominal pain and alternating bowel motion. Those with ulcers were presented with diarrhea and perianal disease. Conclusions Considering the low diagnostic yield of ileal intubation during colonoscopy, the decision to performileoscopy or not during colonoscopy needs to bemade on a case-by-case basis. However, routine ileal intubation, brief attempts should be considered despite low diagnostic yield. (AU)

Intestinal Perforation and Perianal Ulcer Due to Parasitic Infection / Perforación intestinal y úlcera perianal por infección parasitaria

Abstract Balantidium coli is the largest protozoan and the only ciliated parasite that infects humans. It causes balantidiasis, a disease humans acquire by fecal-oral transmission from its usual host: the pig. We report the case of an immunocompetent schoolgirl who presented with peritonitis due to intestinal perforation, with perianal ulceration secondary to polyparasitism caused by Balantidium coli, Enterobius vermicularis, and Trichuris trichiura. It is a rare, potentially preventable complication with extremely high mortality rates. The patient required eight surgical interventions.

Resumen Balantidium coli es el protozoario más grande y el único parásito ciliado que infecta a los seres humanos. Es el causante de la balantidiasis, enfermedad adquirida por los humanos por transmisión fecal-oral desde su hospedero habitual: el cerdo. Reportamos el caso de una escolar inmunocompetente, que presentó peritonitis por perforación intestinal, con ulceración perianal secundaria a poliparasitismo por Balantidium coli, Enterobius vermicularis y Trichuris trichiura. Esta es una complicación poco frecuente, potencialmente prevenible y con tasas de mortalidad extremadamente altas. La paciente requirió 8 intervenciones quirúrgicas.

Factores quirúrgicos, emocionales y cuidado integral tras la cirugía del pie diabético / Surgical, emotional factors and comprehensive care after diabetic foot surgery

El abordaje de un problema de salud tan importante, frecuente y de no fácil solución como es el pie diabético, mejora cuando se constituye un equipo multidisciplinar, ya que en general son varios los profesionales sanitarios implicados en el diagnóstico y tratamiento de este síndrome, cirujanos, endocrinólogos, infecciosos, ortopedas, podólogos y enfermeros; del entendimiento y colaboración de todos ellos debe surgir la mejor manera de encauzarlo correctamente. Objetivo: Analizar los factores quirúrgicos, emocionales y cuidado integral tras la cirugía del pie diabético. Material y método: Revisión bibliográfica con características de estudio de abordaje cualitativo, descriptivo, transversal. Se revisaron serie de revistas con artículos cuyas variables se situaran en pacientes diagnosticados con diabetes mellitus. Resultados: Mujeres 55 y en hombres 45 años, edad media fue 54 años. Sin embrago, la asociación de la edad con el cumplimiento de las conductas de autocuidado en la muestra de pacientes con DM tipo 2 amputados no fue estadísticamente significativa. Así mismo, estos factores influyen en la adherencia al autocuidado de la diabetes, específicamente con las prácticas relacionadas con el cuidado de los pies, correspondiente con una mayor dificultad en la comprensión de las indicaciones. Conclusiones: Se observa en forma general un cumplimiento inadecuado a las conductas de autocuidado para la prevención del pie diabético en la muestra de pacientes diabéticos amputados a pesar de que, la mayoría de las conductas son de bajo costo y requieren poco esfuerzo, evidenciándose escaso acompañamiento por parte del personal sanitario a esta población(AU)

The approach to a health problem as important, frequent and difficult to solve as the diabetic foot, improves when a multidisciplinary team is constituted, since in general there are several health professionals involved in the diagnosis and treatment of this syndrome. surgeons, endocrinologists, infectious, orthopedists, podiatrists and nurses; from the understanding and collaboration of all of them, the best way to channel it correctly must emerge. Objective: To analyze the surgical, emotional and comprehensive care factors after diabetic foot surgery. Material and Method: Bibliographical review with study characteristics of a quantitative, descriptive, cross-sectional approach. A series of journals with articles whose variables were located in patients diagnosed with diabetes mellitus were reviewed. Results: Women 55 and men 45 years, mean age was 54 years. However, the association of age with compliance with self-care behaviors in the sample of amputated patients with type 2 DM was not statistically significant. Likewise, these factors influence adherence to diabetes self- care, specifically with practices related to foot care, related to greater difficulty in understanding the indications. Conclusions: Inadequate compliance with self-care behaviors for the prevention of diabetic foot is generally observed in the sample of amputated diabetic patients, despite the fact that most of the behaviors are low-cost and require little effort, showing little follow-up. by health personnel to this population(AU)

Chlamydia infection resembling ulcerative colitis: case report / Infecção por clamídia lembrando retocolite ulcerativa: relato de caso

Introduction: The diagnosis of ulcerative colitis is relatively complex because the symptoms are similar to those seen in several other diseases. Objective: To report a case of rectal chlamydial infection whose initial symptoms resembled ulcerative colitis. Case report: A 50-year-old male patient presented with diarrhea, blood and mucus in the stools, and an ulcer in the rectum. The histopathological exam pointed to chronic, unspecified inflammation. After a broad serological screening, with Immunoglobulin M positive for Chlamydia and a high titer of immunoglobulin G, the patient was treated with antibiotics and is clinically cured. Later, he remained Immunoglobulin M positive, but the titers of immunoglobulin G lowered considerably. Chlamydia has been shown to live in the gut microbiota, which could explain the case. Conclusion: It is important to search for chlamydial infection as a differential diagnosis of ulcerative colitis.

Introdução: A retocolite ulcerativa é uma condição clínica de diagnóstico relativamente complexo, uma vez que apresenta sinais e sintomas comuns a muitas outras doenças. Objetivo: Relatar um caso de infecção anorretal por clamídia, cujos sintomas iniciais se pareciam com os de retocolite ulcerativa. Relato de caso: Paciente de 50 anos, do sexo masculino, apresentou-se com diarreia, muco e sangue nas fezes, e úlcera no canal anorretal. O exame histopatológico mostrou um processo inflamatório crônico e inespecífico, então procedeu-se a amplo rastreamento sorológico, que revelou Imunoglobulina M positivo para clamídia e altos títulos de Imunoglobulina G. O paciente foi tratado com antibióticos e encontra-se clinicamente curado. No seguimento, permanece com Imunoglobulina M positivo, mas os títulos de Imunoglobulina G decresceram consideravelmente. Bactérias do gênero Chlamydia têm sido reportadas como parte da microbiota intestinal, o que poderia explicar tal comportamento sorológico. Conclusão: É importante rastrear por clamídia como diagnóstico diferencial das suspeitas de retocolite ulcerativa
