Bula gigante secundaria a neumonía adquirida en la comunidad en niños / Giant Bulla Secondary to Community-Acquired Pneumonia in Children

Introducción: Los neumatoceles y las bulas pulmonares son lesiones que se observan en los niños casi siempre asociadas a neumonías infecciosas, aunque sus causas pueden ser diversas. La importancia clínica de estos procesos radica en el peligro de crecimiento progresivo, que puede comprometer las funciones respiratoria y cardiovascular. Objetivo: Describir las experiencias derivadas del proceso de diagnóstico por imágenes y del tratamiento invasivo de casos atendidos. Presentación de los casos: Desde finales de 2021 y durante un período de un año, se atendieron, en la unidad de cuidados intensivos pediátricos del Hospital Pediátrico Universitario de Cienfuegos, cinco niños con neumonías extensas, que desarrollaron bulas de gran tamaño varios días después del tratamiento antimicrobiano adecuado. Estas necesitaron drenaje y aspiración percutáneos debido a su magnitud y a la presencia de síntomas cardiovasculares. Conclusiones: Las bulas que aparecieron como complicación de la neumonía en el niño pueden presentarse con una frecuencia no despreciable, y hay que mantenerse atentos a su evolución, porque, a diferencia de los neumatoceles, pueden crecer progresivamente y comprometer las funciones respiratoria y cardiovascular. El drenaje percutáneo y aspiración continua por cinco días resultó un método seguro y eficaz para tratar estos procesos(AU)

Introduction: Pneumoatoceles and pulmonary bullae are lesions that are observed in children almost always associated with infectious pneumonia, although their causes may be diverse. The clinical importance of these processes lies in the danger of progressive growth, which can compromise respiratory and cardiovascular functions. Objective: To describe the experiences derived from the imaging process and the invasive treatment of treated cases. Presentation of the cases: Since the end of 2021 and for a period of one year, five children with extensive pneumonia were treated in the pediatric intensive care unit of the University Pediatric Hospital of Cienfuegos, who developed large bullae several days after appropriate antimicrobial treatment. The bullae required percutaneous drainage and aspiration due to their magnitude and the presence of cardiovascular symptoms. Conclusions: The bulla that appeared as a complication of pneumonia in the child can occur with a not negligible frequency, and it is necessary to be attentive to their evolution, because, unlike pneumoatoceles, can grow progressively and compromise respiratory and cardiovascular functions. Percutaneous drainage and continuous aspiration for five days was a safe and effective method to treat these processes(AU)

A case of occupational allyl alcohol inhalation poisoning / 中华劳动卫生职业病杂志

Allyl alcohol is an intermediate widely used in industrial production activities, which has caused many occupational damage in China. In this paper, the data of a case of skin damage and clinical cure of inhalation pneumonia caused by occupational allyl alcohol exposure were analyzed and summarized. The patient accidentally inhaled large amounts of allyl alcohol at work and had skin exposure, which was mainly manifested as aspiration pneumonia, respiratory failure, eye damage and skin bullae. After short-term hormone shock therapy, mechanical ventilation, infection prevention, local treatment and other comprehensive treatment, the patient was clinically cured. This case suggests that chemical pneumonia and respiratory failure may be caused by inhalation of allyl alcohol, and skin bullae may be caused by skin contact. Early treatment and hormone use should be emphasized.

The data of gene mutation and specific clinical manifestations were available in 151 and 94 patients,respectively. The main clinical manifestations of KS included poikiloderma,occurrence of blister in childhood,and photosensitivity,and the secondary clinical manifestations included oral inflammation,palmoplantar keratoderma,webbing/pseudoainhum,dysphagia,urethral stricture and so on.Oral inflammation(r=0.234,P=0.023),palmoplantar keratoderma(r=0.325,P=0.001),webbing/pseudoainhum(r=0.247,P=0.016),dysphagia(r=0.333,P=0.001),urethral stricture(r=0.280,P=0.006)were significantly correlated with age,showing significantly higher incidence in the patients over 32 years old.Urethral stricture(χ2=11.292,P=0.001)and anal stenosis(χ2=4.014,P=0.045)were significantly correlated with sex,with higher incidence in males.Eighty different mutations were found in 151 patients,and the most common gene mutation was c.676C>T.Forty-one tumors occurred in 27 patients,among which squamous cell carcinoma accounted for 92.7%. The gene mutation site had no significant correlation with squamous cell carcinoma or patient country. Conclusions The c.676C>T in FERMT1 gene is the most common mutation in KS.The patients are prone to squamous cell carcinoma and mainly attacked at the exposure sites(hand and mouth).

A cross-sectional investigation and analysis of early treatment of partial-thickness burn wounds by professional burn medical staff in China / 中华烧伤杂志

Objective: To assess the current situation of early treatment of partial-thickness burn wounds by professional burn medical staff in China, and to further promote the standardized early clinical treatment of partial-thickness burn wounds. Methods: A cross-sectional investigation was conducted. From November 2020 to February 2021, the self-designed questionnaire for the early treatment of partial-thickness burn wounds was published through the "questionnaire star" website and shared through WeChat to conduct a convenient sampling survey of domestic medical staff engaged in burn specialty who met the inclusion criteria. The number, region, and grade of the affiliated hospital, the age, gender, occupation, and seniority of the respondents were recorded. The respondents were divided into physician group and nurse group, senior group and junior group, eastern region group and non-eastern region group, primary and secondary hospital group and tertiary hospital group. Then the seniority, grade of the affiliated hospital, region of the affiliated hospital of the respondents in physician group and nurse group, conventional treatment of partial-thickness burn blisters, reasons for retaining vesicular skin, reasons for removing vesicular skin, and the conventional selection and optimal solution recommendation of topical drugs or dressings for partial-thickness burn wounds in the early stage of respondents in each of all the groups were recorded. Data were statistically analyzed with chi-square test. Results: The survey covered 31 provinces, municipalities, and autonomous regions in China (except for Hong Kong, Macau, and Taiwan regions). A total of 979 questionnaires were recovered, which were all valid. The 979 respondents came from 449 hospitals across the country, including 203 hospitals in the eastern region, 116 hospitals in the western region, 99 hospitals in the central region, and 31 hospitals in the northeast region, 348 tertiary hospitals, 79 secondary hospitals, and 22 primary hospitals. The age of the respondents was (39±10) years. There were 543 males and 436 females, 656 physicians and 323 nurses, 473 juniors and 506 seniors, 460 in the eastern regions and 519 in the non-eastern regions, 818 in tertiary hospitals and 161 in primary and secondary hospitals. There were statistically significant differences in the composition of different seniority in the respondents between physician group and nurse group (χ2=44.32, P<0.01), while there were no statistically significant differences in grade or region of the affiliated hospital of the respondents between physician group and nurse group (P>0.05). There were no statistically significant differences in the conventional treatment of partial-thickness burn blisters among respondents between different occupational groups, seniority groups, and region of the affiliated hospital groups (P>0.05).The respondents in different grade of the affiliated hospital groups differed significantly in the conventional treatment of partial-thickness burn blisters (χ2=6.24, P<0.05). Compared with respondents in nurse group, larger percentage of respondents in physician group chose to retain vesicular skin for protecting the wounds and providing a moist environment, and alleviating the pain of dressing change (with χ2 values of 21.22 and 19.96, respectively, P values below 0.01), and smaller percentage of respondents in physician group chose to retain vesicular skin for prevention of wound infection (χ2=23.55, P<0.01). The reasons for retaining vesicular skin of respondents between physician group and nurse group were similar in accelerating wound healing, alleviating pigmentation and scar hyperplasia post wound healing (P>0.05). Compared with respondents in junior group, larger percentage of respondents in senior group chose to retain vesicular skin for protecting the wounds and providing a moist environment and alleviating the pain of dressing change (with χ2 values of 10.36 and 4.60, respectively, P<0.05 or P<0.01), and smaller percentage of respondents in senior group chose to retain vesicular skin for prevention of wound infection (χ2=8.20, P<0.01). The reasons for retaining vesicular skin of respondents in senior group and junior group were similar in accelerating wound healing, alleviating pigmentation and scar hyperplasia post wound healing (P>0.05). The 5 reasons for the respondents between eastern region group and non-eastern region group, primary and secondary hospital group and tertiary hospital group chose to retain vesicular skin were all similar (P>0.05). Compared with those in physician group, significantly higher percentage of respondents in nurse group were in favor of the following 6 reasons for removing the vesicular skin, including convenience for using more ideal dressings to protect the wounds, prevention of wound infection, facilitating the effect of topical drugs on the wounds, the likely rupture of blisters and wound contamination, accelerating wound healing, and alleviating pigmentation and scar hyperplasia post wound healing (with χ2 values of 4.35, 25.59, 11.83, 16.76, 46.31, and 17.54, respectively, P<0.05 or P<0.01). Compared with respondents in senior group, larger percentage of respondents in junior group chose to remove vesicular skin for the reasons such as the likely blister rupture and wound contamination, preventing wound infection, accelerating wound healing, and alleviating pigmentation and scar hyperplasia post wound healing (with χ2 values of 17.25, 18.63, 14.83, and 10.23, respectively, P values below 0.01). Compared with respondents in non-eastern region group, larger percentage of respondents in eastern region group chose to remove vesicular skin for preventing wound infection and the likely rupture of blisters and wound contamination (with χ2 values of 9.30 and 8.65, respectively, P values below 0.01). The 6 reasons for the respondents between tertiary hospital group and primary and secondary hospital group choose to remove vesicular skin were similar (P>0.05). Compared with respondents in physician group, larger percentage of respondents in nurse group chose to use moisturizing materials for partial-thickness burn wounds in the early stage (χ2=6.18, P<0.05), and smaller percentage of respondents in nurse group chose other topical drugs or dressings (χ2=5.20, P<0.05). Compared with respondents in junior group, larger percentage of respondents in senior group chose to use moisturizing materials and other topical drugs or dressings for partial-thickness burn wounds in the early stage (with χ2 values of 4.97 and 21.80, respectively, P<0.05 or P<0.01). Compared with respondents in non-eastern region group, larger percentage of respondents in eastern region group chose to use topical antimicrobial drugs for partial-thickness burn wounds in the early stage (χ2=4.09, P<0.05), and smaller percentage of respondents in eastern region group chose to use other topical drugs or dressings for the partial-thickness burn wounds in the early stage (χ2=5.63, P<0.05). Compared with respondents in primary and secondary hospital group, larger percentage of respondents in tertiary hospital group chose to use biological dressings for partial-thickness burn wounds in the early stage (χ2=9.38, P<0.01). The optimal solution recommendation of topical drugs or dressings for partial-thickness burn wounds in the early stage varied significantly among the respondents between different occupational groups and seniority groups (with χ2 values of 39.58 and 19.93, respectively, P values below 0.01). There were no statistically significant differences between eastern and non-eastern region groups, tertiary hospital group and primary and secondary hospital groups in optimal solution recommendation of topical drugs or dressings for partial-thickness burn wounds in the early stage (P>0.05). Conclusions: The conventional treatment measures of partial-thickness burn blisters and reasons for preserving blister skin by professional burn medical staff in China are relatively consistent, but there are great differences in the selection of reasons for removing blister skin, the conventional selection and optimal solution recommendation of topical drugs or dressings for partial-thickness burn wounds in the early stage. Therefore, it is urgent to establish a clinical treatment standard for partial-thickness burn wounds.

Eritema nodoso hansênico com apresentação vesiculosa simulando infecção herpética: um relato de caso / Erythema nodosum leprosum with vesicular presentation simulating herpetic infection: a case report

Contexto: As reações hansênicas são episódios inflamatórios agudos imunomediados que podem ocorrer em indivíduos com hanseníase. Lesões atípicas de eritema nodoso hansênico (ENH) são raras e podem se apresentar como pústulas, bolhas, necrose, úlceras e, eventualmente, podem simular outras doenças como a síndrome de Sweet e eritema multiforme. Descrição do caso: Paciente do sexo masculino, 24 anos de idade, com diagnóstico prévio de hanseníase virchowiana e realização de tratamento adequado, com término da poliquimioterapia quatro anos antes de comparecer ao nosso serviço quando foi avaliado, apresentando pequenas vesículas translúcidas agrupadas sobre uma base eritematosa e áreas com crostas necróticas, simulando lesões herpéticas, na porção superior das costas, parte inferior do pescoço e haste do pênis. O exame histopatológico da biópsia cutânea foi sugestivo de reação tipo 2 e o tratamento com talidomida foi satisfatório. Discussão: As reações na hanseníase representam episódios de hipersensibilidade aguda a antígenos de Mycobacterium leprae e podem se desenvolver antes, durante ou após o término do tratamento. Acredita-se que o ENH, ou reações do tipo 2, ocorram devido à deposição de imunocomplexos em múltiplos órgãos em pacientes que apresentam a forma multibacilar. Conclusões: As reações hansênicas são desafios no manejo da hanseníase, especialmente pelo fato de a maioria das sequelas permanentes ser secundária a esses episódios inflamatórios agudos. O conhecimento das possíveis apresentações atípicas das reações hansênicas é fundamental para o diagnóstico precoce e o tratamento adequado, a fim de prevenir morbidade grave relacionada à hanseníase.

Adenocarcinoma mucinoso de vesícula biliar originado en neoplasia papilar intracolecística / Mucinous adenocarcinoma of the gallbladder originated from intracholecystic papillary neoplasm

RESUMEN La neoplasia papilar intracolecística con carcinoma mucinoso invasor y células en anillo de sello es una variedad de cáncer de vesícula, una patología agresiva y con mal pronóstico, la cual puede presentarse en forma similar a una colecistitis y, a pesar del tratamiento operatorio y quimioterapia posterior, la supervivencia y pronóstico son peores en relación con los otros cánceres de vesícula.

ABSTRACT Intracholecystic papillary neoplasm with invasive mucinous adenocarcinoma and signet ring cells is a rare, aggressive variety of gallbladder cancer, with symptoms mimicking cholecystitis. Survival and prognosis are worse that other types of gallbladder cancer despite surgery and chemotherapy. The aim of this article is to describe a case of a rare gallbladder cancer with specific histology and the treatment performed

Gene panel for the diagnosis of epidermolysis bullosa: proposal for a viable and efficient approach

Abstract Background: Epidermolysis bullosa is characterized by cutaneous fragility and blistering. Historically, diagnosis is achieved by immunofluorescence mapping or transmission electron microscopy, both involving biopsy procedures. Genetic analysis, especially through next-generation sequencing, is an important tool for the diagnosis of this disease. In Brazil, access to diagnostic methods is limited, and consequently, most patients do not have an accurate diagnosis. Diagnosis allows the indication of prognosis and genetic counselling of the patient. Objectives: To evaluate the cost-effectiveness of a gene panel compared to immunofluorescence mapping and transmission electron microscopy by analyzing its benefits, limitations, and economic aspects. Methods: The gene panel included the 11 main genes associated with epidermolysis bullosa. The techniques were compared, assessing the average cost, advantages, and limitations, through a price survey and literature review. Results: Both immunofluorescence mapping and transmission electron microscopy require skin biopsy, are dependent on the investigator's expertise, and are subject to frequent inconclusive results. The gene panel is effective for the conclusive diagnosis of epidermolysis bullosa, presents high efficiency and accuracy, is economically feasible, and excludes the need for biopsy. The gene panel allows for prognosis, prenatal genetic diagnosis, and genetic counseling. Study limitations: It was not possible to find laboratories that perform transmission electron microscopy for epidermolysis bullosa diagnosis in Brazil. Conclusion: This study supports the gene panel as the first-choice method for epidermolysis bullosa diagnosis.

Tercer caso de vasculitis leucocitoclástica cutánea secundaria al uso de oxacilina: reporte de caso / Third case in the literature of cutaneous leukocytoclastic vasculitis secondary to oxacilin use

Resumen La vasculitis leucocitoclastica es una patologìa que compromete los vasos pequeños y cuya causa predominantemente se ha descrito como idiopatica. Se presenta el caso de una mujer de 78 años hipertensa, diabética y con enfermedad renal crónica en estadio 5, que presentó lesiones limitadas a la piel posterior a la administración de oxacilina para manejo de bacteremia por SAMS. La presentación clínica se basó en purpuras palpables predominantemente en miembros inferiores y lesiones dolorosas coalescentes que formaban ampollas de contenido hemorrágico. Estas lesiones resolvieron gradualmente después del cambio de la terapia mencionada anteriormente. La biopsia fue compatible con vasculitis leucocitoclástica, con paraclínicos que descartaron causas infecciosas y autoinmunes.

Abstract Leukocytoclastic vasculitis is a pathology that involves small vessels and whose cause has been predominantly described as idiopathic. The clinical case of a 78-year-old woman with hypertension, diabetic and chronic stage 5 kidney disease, who presented limited skin lesions after administration of oxacillin for management of bacteremia by MSSA. The clinical presentation consisted on palpable purpura predominantly in the lower limbs and painful coalescent lesions that formed blisters of hemorrhagic content. Lesions gradually resolved after the change of the therapy mentioned above. The biopsy was compatible with leukocytocastic vasculitis, with paraclinics who ruled out infectious and autoimmune causes.

Agenesia de la vesícula biliar / Agenesia of the gallbladder

La agenesia de la vesícula biliar (AVB) es una entidad congénita rara. La mayoría de los pacientes, permanecen asintomáticos, mientras que los que presentan síntomas informan síntomas que imitan el cólico biliar. La evaluación inicial para la sospecha de patología de la vesícula biliar, como la ecografía del cuadrante superior derecho, Puede ser engañosa o no concluyente. En consecuencia, algunos pacientes son finalmente diagnosticados intra-operatoriamente. Por lo tanto, deben mantener la AVB como un diagnóstico diferencial y deben realizarse como la colangiopancreatografía por resonancia magnética (CPRMN) cuando otras pruebas no sean concluyentes. Presentamos una mujer de 39 años que presento síntomas crónicos compatibles con cólico biliar y una ecografía equívoca informada como escleroatrófica con colelitiasis. Se le realizó laparoscopia durante la cual se constató la ausencia de vesícula biliar. La CPRM posoperatoria confirmó el diagnóstico de AG.

Gallbladder agenesis (GA) is a rare congenital entity. Most patients remain asymptomatic, while those with symptoms report symptoms that mimic bile colic. Initial evaluation for suspected gallbladder pathology, such as ultrasound of the right upper quadrant, May be misleading or inconclusive. As a result, some patients are eventually diagnosed intra-operatively. Therefore, GA should be maintained as a differential diagnosis and should be performed as magnetic resonance cholangiopancreatography (MRI) when other tests are inconclusive. We present a 39-year-old woman who has chronic symptoms compatible with biliary colic and an equivocal ultrasound reported as scleroatrofic with cholelithiasis. Laparoscopy was performed during which the absence of gallbladder was found. Postoperative CPRM confirmed the diagnosis of GA.

Vesícula multiseptada, causa de dolor abdominal crónico / Septal gallbladder as a cause of chronic abdominal pain

Las malformaciones congénitas de la vesícula son variadas y algunas de ellas muy raras, como es el caso de la vesícula tabicada. Esta no es una patología frecuente, generalmente es un hallazgo imagenológico incidental en pacientes con dolor abdominal crónico, la mayoría de ellos adultos mayores, por lo que es importante conocerla y reconocerla. Se puede diagnosticar con todos los métodos de imagen, desde la ecografía hasta la resonancia magnética, por lo cual cobra importancia para los profesionales de esta rama tener conocimiento claro de sus manifestaciones.

Congenital malformations of the gallbladder are varied and some of them are very rare, as is the case of the septal gallbladder. This is not a frequent pathology, it is usually an incidental imaging finding in patients with chronic abdominal pain, most of them older adults, so it is important to know and recognize it. It can be diagnosed with all imaging methods from ultrasound to magnetic resonance, which is why it is important for professionals in this branch to know and recognize it.

Inherited epidermolysis bullosa: update on the clinical and genetic aspects

Abstract Inherited epidermolysis bullosa is a group of genetic diseases characterized by skin fragility and blistering on the skin and mucous membranes in response to minimal trauma. Epidermolysis bullosa is clinically and genetically very heterogeneous, being classified into four main types according to the layer of skin in which blistering occurs: epidermolysis bullosa simplex (intraepidermal), junctional epidermolysis bullosa (within the lamina lucida of the basement membrane), dystrophic epidermolysis bullosa (below the basement membrane), and Kindler epidermolysis bullosa (mixed skin cleavage pattern). Furthermore, epidermolysis bullosa is stratified into several subtypes, which consider the clinical characteristics, the distribution of the blisters, and the severity of cutaneous and extracutaneous signs. Pathogenic variants in at least 16 genes that encode proteins essential for the integrity and adhesion of skin layers have already been associated with different subtypes of epidermolysis bullosa. The marked heterogeneity of the disease, which includes phenotypes with a broad spectrum of severity and many causal genes, hinders its classification and diagnosis. For this reason, dermatologists and geneticists regularly review and update the classification criteria. This review aimed to update the state of the art on inherited epidermolysis bullosa, with a special focus on the associated clinical and genetic aspects, presenting data from the most recent reclassification consensus, published in 2020.

Trichoscopic stages of dissecting cellulitis: a potential complementary tool to clinical assessment

Abstract Dissecting cellulitis is a chronic, progressive, and relapsing inflammatory disease that predominantly affects the vertex and occiput of young Afro-descendent men. It starts with papules and pustules that evolve to nodules, abscesses, and cicatricial alopecia. This article illustrates the evolutive trichoscopy of dissecting cellulitis, from its early phase, through the abscess phase, to the fibrotic cicatricial phase. Trichoscopy complements clinical-pathological classification, representing a complementary tool useful in early diagnosis and monitoring of the patient during treatment.

Acute fever with rash, necrosis, and bullae in both lower extremities in a 12-year-old girl / 中国当代儿科杂志

A girl, aged 12 years, was admitted due to fever and rash for 3 days. The child developed recurrent high fever and rash on both lower extremities 3 days before, and the rash on left lower extremity quickly merged into a patch within 24 hours, with hemorrhage and necrosis in black and purple, large vesicles, and blisters in the center. Laboratory examination showed a reduction in platelet count and significant increases in fibrinogen and D-dimer during the course of the disease. The child was diagnosed with purpura flulminans. She was given meropenem combined with linezolid for anti-infection, injection of gamma globulin for immunoregulation, and low-molecular-weight heparin for anticoagulation. The fluid in the rash blisters was drawn and the wound was treated to prevent infection. The child's temperature returned to normal, with improvement in gangrene. She was discharged after platelet count, fibrinogen, and D-dimer had returned to normal. Purpura fulminans is a rare thrombotic hemorrhagic disease with rapid progression and is commonly seen in children. Without timely treatment, it may cause severe sequelae with high disability and mortality rates. Anti-infection, correction of coagulation function, and local management of gangrene skin are of great importance during treatment.

A case of toxic epidermal necrolysis induced by cytomegalovirus infection followed by DRESS (drug reaction with eosinophilia and systemic symptoms)

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and toxic epidermal necrolysis (TEN) are severe cutaneous adverse reactions. Although viral reactivation is associated with DRESS syndrome, its role in TEN remains unclear. An 80-year-old woman visited our hospital because of fever and skin eruption. DRESS syndrome was diagnosed and was thought to caused by the use of the drug allopurinol. She was treated by discontinuation of the drug and administration of systemic steroids. She recovered from DRESS syndrome and was discharged from the hospital with tapering doses of steroids prescribed. One week after discharge, she visited our hospital again as the skin rash recurred and oral pain as well as oral and ocular mucosal lesions developed. In addition to the skin rash, blisters and Nikolsky's sign that were different from the skin lesions present in the previous DRESS syndrome were observed. Unlike those in DRESS syndrome, the viral serological test results were positive for anti-cytomegalovirus (CMV) IgM and CMV polymerase chain reaction. Therefore, it was thought that TEN was due to reactivation of CMV and she was treated this with ganciclovir and intravenous immunoglobulin. Here, we report a case of TEN caused by viral reactivation after DRESS syndrome developed after use of allopurinol which recovered after steroid treatment.
