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)

Bullosis diabeticorum ­ una lesión poco común / Bullosis diabeticorum ­ an uncommon lesion

IINTRODUCCIÓN: el bullosis diabeticorum forma parte del espectro de manifestaciones cutáneas de la diabetes mellitus, descrito por Kramer en 1930 y nombrado como bullosis diabeticorum por Cantwell y Martz. Es una enfermedad conocida, pero bastante rara (0.5 a 2% de la población diabética) siendo dos veces más común en hombres. Es una lesión espontánea y no está relacionada con trauma o causa fisiológica evidente, como infección, 3 que no causa dolor o se asocia a signos flogísticos. Se asocia principalmente a las extremidades, pudiendo ser una lesión única o múltiples lesiones. Puede ocurrir en la diabetes mellitus tipo 1 (DM1) y en el tipo 2. Las lesiones típicamente se curan espontáneamente de 2 a 6 semanas, pero pueden ocurrir en el mismo lugar nuevamente. El pronóstico es bueno, sin tratamiento específico necesario o seguimiento diagnóstico con biopsia. Se relata un caso de esta rara patología con documentación por resonancia magnética.

Bullosis diabeticorum is part of the spectrum of cutaneous manifestations of diabetes mellitus, described by Kramer in 1930 and named bullosis diabeticorum by Cantwell and Martz. It is a known disease, but quite rare (0.5 to 2% of the diabetic population) and is two times more common in men. Bullosis diabeticorum is a spontaneous lesion and not related to trauma or obvious physiological cause, such as infection that does not cause pain or is associated with inflammatory signs. Occurs at the limbs and may be single or multiple. It can occur in diabetes mellitus type 1 (DM1) and type 2, usually in the advanced stages. The lesions heal spontaneously typically in 2 to 6 weeks, but they may happen again on the same site. The prognosis is good with no need of special treatment or further diagnosis with biopsy. We report a case of this rare complication with magnetic resonance imaging.

Púrpura de Schönlein-Henoch Buloso. Caso clínico / Bullous Henoch-Schönlein purpura. Case report

Resumen: Introducción: El púrpura de Schonlein-Henoch (PSH) O Vasculitis IgA es la vasculitis sistémica más frecuente de la edad pediátrica. Se manifiesta clínicamente como púrpura palpable, artralgias, dolor abdominal y compromiso renal. El púrpura palpable buloso a diferencia de lo que ocurre en la edad adulta, es muy infrecuente en la infancia. Objetivo: Reportar una forma infrecuente de presentación cutánea del PSH en niños. Caso clínico: Niña de 14 años con historia de 2 semanas con ampollas dolorosas múltiples y confluentes en ambas extremidades inferiores asociado a artralgias. A la histo-patología destacan vesículas intracórneas, epidermis con acantosis y espongiosis e infiltrado dérmico perivascular. Inmunofluorescencia directa (+) para IgA. Se plantea el diagnóstico de PSH ampollar y se realiza tratamiento inicial con corticoides intravenosos. A los tres días del traslape a corticoides orales aparecen nuevas lesiones equimóticas en ambas piernas. Se decide asociar azatriopina e iniciar descenso de corticoides, obteniéndose buena respuesta. Conclusión: Si bien la formación de bulas en el PSH no agrega morbilidad, suele ser un fenómeno alarmante que requiere realizar diagnóstico di ferencial con otras patologías. El uso de corticoides estaría indicado en estos casos ya que disminuiría la producción de las metaloproteinsas responsables de la formación de las bulas.

Abstract: Henoch-Schönlein purpura (HSP) or IgA Vasculitis is the most common childhood vasculitis. The classic tetrad of signs and symptoms include palpable purpura, arthralgia, abdominal pain and renal disease. The occurrence of hemorrhagic bullae in children with HSP is rarely encountered. Objec tive: To report an unusual cutaneous manifestation of HSP in children. Case report: A 14-year-old girl complained about a 2-week painful bullous rash in both lower extremities and multiple arthral gias. There was no history of abdominal pain or urinary symptoms. In both lower extremities, there were numerous palpable purpura and hemmorrhagic bullae. In light of clinical findings, laboratory tests and skin biopsy are requested. The histopathology described intraepidermal blisters, acanthosis, spongiosis and perivascular dermal infiltrate. Direct immunofluorescence (IFD) (+) for IgA. The diagnosis of bullous HSP was made and treatment with endovenous corticosteroids was initiated. Three days after overlapping to oral corticosteroids, new ecchymotic lesions appeared in both legs. Due to the persistence of cutaneous involvement and negative control tests, azathioprine was associa ted obtaining a good response. Conclusion: Although bullous lesions in HSP does not add morbidity, it is often an alarming phenomenon with multiple differential diagnoses. The anti-inflamatory effect of corticoids is likely to be beneficial in the treatment of patients with severe cutaneous involvement through inhibition of proinflammatory transcription factors and decreasing the production of the metalloproteinases.

Algorithm approach for revision surgery following late-onset bleb complications after trabeculectomy: long-term follow-up / Algoritmo de abordagem para cirurgia de revisão nas complicações da bolha de início tardio após trabeculectomia: acompanhamento de longo prazo

ABSTRACT Purpose: The aim of this study was to introduce a reproducible algorithm for the surgical management of late-onset (>2 months) bleb complications after trabeculectomy with mitomycin C. Methods: We performed a retrospective review of eyes treated using a reproducible algorithm approach by a single surgeon for the surgical management of late-onset bleb complications from July 2006 to April 2014. Exclusion criteria were bleb revision with less than 3 months of follow-up or bleb revision combined with other glaucoma procedures at the time of surgery. Success was evaluated using the Kaplan-Meier survival method and defined as achieving all of the following criteria: primary surgery indication resolved, no additional surgery required for decreasing the intraocular pressure (IOP), and IOP of ≥6 mmHg and ≤18 mmHg. Results: Twenty-three eyes from 20 patients were evaluated. Indications for bleb revision were hypotonic maculopathy (47.8%), bleb leak (30.4%), and dysesthetic bleb (21.7%). The overall primary outcome success rate calculated using the Kaplan-Meier survival method was 65.2% at 48 months. When the IOP target was changed to ≤15 mmHg, the bleb survival rate was 47.8% at 48 months. At the most recent postoperative visit, 95.7% of eyes had an IOP of ≤15 mmHg and 56.5% were being treated with an average of one medication per eye. One eye (4.3%) required a second bleb revision for persistent hypotony and two eyes required glaucoma surgery to reduce IOP during follow-up. Conclusions: An algorithm approach for the surgical management of late-onset bleb complications with a success rate similar to those reported in specialized literature is proposed. Randomized trials are needed to confirm the best surgical approach.

RESUMO Objetivo: Descrever um algoritmo reprodutível para o tratamento cirúrgico das complicações da bolha de início tardio (>2 meses) após trabeculectomia com mitomicina-C. Métodos: Revisão retrospectiva de olhos que foram submetidos a um algoritmo reprodutível para o tratamento cirúrgico das complicações da bolha de início tardio por um único cirurgião, de julho de 2006 a abril de 2014. Os critérios de exclusão foram revisão de bolha com menos de 3 meses de seguimento ou revisão de bolha combinado com outro procedimento antiglaucomatoso no momento da cirurgia. O sucesso foi avaliado pelo método de sobrevida de Kaplan-Meier e definidos como ter atingido todos os seguintes critérios: indicação de cirurgia primária resolvido, nenhuma cirurgia adicional necessária para diminuir a pressão intraocular (IOP), IOP ≥6 mmHg e ≤18 mmHg. Resultados: Vinte e três olhos de 20 pacientes foram incluídos. Indicações para revisão bolha foram maculopatia hipotônica (47,8%), extravasamento da bolha (30,4%) e bolha elevada (21,7%). A taxa de sucesso do resultado primário global calculada pelo método de sobrevivência de Kaplan-Meier foi de 65,2% aos 48 meses. Quando a IOP foi diminuída para ≤15mmHg, a taxa de sobrevivência bolha foi de 47,8% em 48 meses. Na visita pós-operatória mais recente, 95,7% dos olhos apresentavam PIO ≤15mmHg e 56,5% estavam sob tratamento com uma média de um medicamento por olho. Um olho (4,3%) necessitou de uma segunda revisão da bolha para hipotonia persistente e dois olhos necessitaram cirurgia de antiglaucomatosa para reduzir a IOP durante o seguimento. Conclusões: Um algoritmo de abordagem para o tratamento cirúrgico das complicações tardias da bolha com uma taxa de sucesso semelhante aos relatados na literatura especializada é proposto. Ensaios clínicos randomizados são necessários para confirmar a melhor abordagem cirúrgica.

Early transconjunctival needling revision with 5-fluorouracil versus medical treatment in encapsulated blebs: a 12-month prospective study

OBJECTIVE: To compare the efficacy of transconjunctival needling revision with 5-fluorouracil versus medical treatment in glaucomatous eyes with uncontrolled intraocular pressure due to encapsulated bleb after trabeculectomy. METHODS: Prospective, randomized, interventional study. A total of 40 eyes in 39 patients with elevated intraocular pressure and encapsulated blebs diagnosed at a maximum five months after primary trabeculectomy with mitomycin C were included. The eyes were randomized to either transconjunctival needling revision with 5- fluorouracil or medical treatment (hypotensive eyedrops). A maximum of two transconjunctival needling revisions per patient was allowed in the needling arm. All patients underwent follow-up for 12 months. Successful treatment was defined as an intraocular pressure ≤ 18 mmHg and a 20% reduction from baseline at the final follow-up. Clinicaltrial.gov: NCT01887223. RESULTS: Mean intraocular pressure at the final 12-month follow-up was lower in the transconjunctival needling revision group compared to the medical treatment group. Similar numbers of eyes reached the criteria for treatment success in both the transconjunctival needling revision group and the medical treatment group. CONCLUSIONS: Despite similar success rates in eyes randomized to transconjunctival needling revision with 5-fluorouracil compared to eyes receiving medical treatment, there was a significantly lower mean intraocular pressure at 12 months after transconjunctival needling revision. .

Extensive Bullous Complication Associated with Intermittent Pneumatic Compression

Intermittent pneumatic compression (IPC) device is an effective method to prevent deep vein thrombosis. This method has been known to be safe with very low rate of complications compared to medical thromboprophylaxis. Therefore, this modality has been used widely in patients who underwent a hip fracture surgery. We report a patient who developed extensive bullae, a potentially serious skin complication, beneath the leg sleeves during the use of IPC device after hip fracture surgery.

Etiology and epidemiological analysis of glaucoma-filtering bleb infections in a tertiary eye care hospital in south India.

Purpose: To evaluate the microbial etiology and associated risk factors among patients with blebitis following trabeculectomy. Materials and Methods: A retrospective analysis of all culture-proven blebitis was performed in patients who underwent trabeculectomy between January 2004 and December 2008. A standardized form was filled out for each patient, documenting sociodemographic features and information pertaining to risk factors. Swabbing of the infected bleb surface was performed for all suspected cases and further subjected to microbiological analysis. Results: A total of 23 patients with culture-proven blebitis were treated during the study period, with a mean age of 59.2 years (59.2 ± SD: 12.8; range, 30-81 years). Duration of onset was early (≤36 months) in six (26%) cases and late (> 36 months) in 17 (74%) cases with a range between 15 and 144 months (mean, 82.91 months; SD: 41.89). All 23 blebs were located superiorly and of which, 21 (91%) were microcystic avascular, 1 (4%) diffuse avascular, and 1 (4%) vascular flattened. The predominant risk factor identified was bleb leak (35%; 8 of 23) followed by thin bleb (22%; 5 of 23) and blepharitis (17%; 4 of 23). Bleb leaks (100%) were recorded only in patients with late onset (≥ 9 years) of infection (P< 0.001), while the incidence of ocular surface disease (100%) occurred early (≤3 years) (P< 0.001). Use of topical steroids was associated frequently with cases of thin blebs (80%; 4 of 5) (P< 0.001), while topical antibiotics showed bleb leaks (88%; 7 of 8) (P< 0.001). Coagulase-positive staphylococci were frequently recovered from blebitis with thin blebs (71%; 5 of 7) (P = 0.001), Coagulase-negative staphylococci (CoNS) with bleb leak (100%; 8 of 8) (P< 0.001), Corynebacterium with blepharitis (100%; 3 of 3) (P = 0.001), and Streptococci with releasable sutures (75%; 3 of 4) (P = 0.001). Conclusion Bleb leak is the principal risk factor responsible for late-onset blebitis, while early-onset blebitis could be ascribed to ocular surface diseases. Streptococci were mainly responsible for early onset of infection, while the late onset was due to CoNS.

Diagnosis and treatment of hyperfiltering blebs / Diagnóstico e tratamento de bolsas fistulantes hiperfuncionantes

PURPOSE: To report on a new treatment for hyperfiltering bleb as well as its diagnostic criteria. METHODS: Twenty eyes with hypotony due to hyperfiltering bleb caused by trabeculectomy with mitomicin C were treated with bleb resection. The diagnosis of hyperfiltering bleb followed these criteria: intraocular pressure lower than six mmHg (Goldmann tonometer); no inflammation in the anterior segment; presence of an elevated and/or diffuse and avascular bleb with or without microcysts; negative Seidel test; no ciliochoroidal detachment found with ultrasound biomicroscopy. We registered the following data pre and post operatively: type of glaucoma, visual acuity, bleb aspect and fundoscopic findings. A successful resolution of hypotony was achieved when intraocular pressure ranged from six to 14 mmHg with or without antiglaucomatous medication. RESULTS: At a minimum follow-up of 19 months ocular hypotony had been reversed in all eyes. At the last exam, intraocular pressure varied from eight to 14 mmHg in 18 (90 percent) eyes; 12 (66.7 percent) eyes had no medication and six (33.3 percent) used antiglaucomatous medication. In two (10 percent) eyes, another trabeculectomy was necessary to control intraocular pressure. Hypotonic maculopathy developed preoperatively in seven eyes and was reversed after bleb resection. Visual acuity improved in 15 (75 percent) eyes but did not change in five (25 percent). CONCLUSION: Bleb resection is a safe and adequate treatment for ocular hypotony due to hyperfiltering bleb. It also restores vision in a considerable number of patients. The diagnosis of hyperfiltering bleb must follow rigorous criteria.

OBJETIVO: Relatar os resultados de uma nova técnica para o tratamento de bolsa hiperfuncionante, assim como seus critérios diagnósticos. MÉTODOS: Vinte olhos (20 pacientes) com hipotonia ocular causada por bolsa hiperfuncionante após trabeculectomia com mitomicina C foram tratados com ressecção da bolsa. O diagnóstico de bolsa hiperfuncionante obedeceu aos seguintes critérios: pressão intraocular inferior a seis mmHg (tonometria de Goldmann); ausência de inflamação do segmento anterior ocular; presença de bolsa fistulante elevada e/ou difusa e avascular com ou sem microcistos; teste de Seidel negativo; ausência de descolamento ciliocoroidiano ao exame de UBM. Foram registrados no pré e pós-operatório: o tipo de glaucoma, a acuidade visual, o aspecto da bolsa e os achados oftalmoscópicos. A resolução da hipotonia foi alcançada quando a pressão intraocular variou de seis a 14 mmHg sem ou sob medicação tópica antiglaucomatosa. RESULTADOS: No seguimento mínimo de 19 meses, a hipotonia ocular foi revertida nos 20 olhos. No último exame, a pressão intraocular variou de oito a 14 mmHg em 18 (90 por cento) olhos; 12 (66,7 por cento) olhos sem medicação e seis (33,3 por cento) olhos sob medicação tópica. Em dois (20 por cento) olhos foi necessário nova trabeculetomia para controle da pressão intraocular. Maculopatia hipotônica foi diagnosticada no pré-operatório em sete olhos e foi revertida em todos eles após a ressecção da bolsa. A acuidade visual melhorou em 15 (75 por cento) olhos e não se alterou em cinco (25 por cento). CONCLUSÃO: A ressecção da bolsa é eficaz no tratamento da hipotonia ocular consequente a sua hiperfunção. Esse procedimento também recupera a visão num considerável número de pacientes. O diagnóstico de bolsa hiperfuncionante deve obedecer a critérios rigorosos.

Simultaneous bilensectomy and endothelial keratoplasty for angle-supported phakic intraocular lens-induced corneal decompensation.

A 40-year-old lady presented with severe endothelial cell loss in both eyes 14 years after angle-supported phakic intraocular lens (AS PIOL) implantation. The left eye had severe corneal edema with bullous keratopathy. The right eye had markedly reduced endothelial cell count (655 cells/mm2) although the cornea was clear. She underwent simultaneous bilensectomy (AS PIOL explantation and phacoemulsification) and Descemet's stripping and endothelial keratoplasty (DSEK) in the left eye. Explanted AS PIOL was identified as ZSAL-4 (Morcher, Stuttgart, Germany) model. Corneal edema cleared completely in 2 months with a best corrected visual acuity (-2.25 D sph) of 20/60. No intervention was done in the right eye. The present case illustrates that AS PIOL-induced endothelial decompensation can be effectively managed by simultaneous bilensectomy and endothelial keratoplasty.

Tungiasis inusual: forma clínica ampollar / Unusual tungiasis: bullous lesions

La tungiasis es una ectoparasitosis cutánea producida por la hembra fecundada de la pulga de arena Tunga penetrans, cuya mayor prevalencia ocurre en África Sub-sahariana, Sudamérica y el Caribe. Comunicamos dos casos de pacientes que presentaron lesiones ampollares sugestivas de tungiasis al retornar de Ferrugem (Brasil) y Misiones (Argentina) respectivamente. El diagnóstico de tungiasis fue confirmado en ambos casos. Se revisa la historia, epidemiología y biología de la tungiasis. Se plantean hipótesis sobre la patogenia de la forma clínica ampollar.

Tungiasis is a cutaneous ectoparasitosis caused by the gravid femalesand flea Tunga penetrans,whose higher prevalence occurs in Sub-Saha-ran Africa, South America and the Caribbean. We report two males whopresented bullous lesions suggestive of tungiasis on their return fromFerrugem (Brazil) and Misiones (Argentina). The diagnosis of tungiasiswas confi rmed in both cases.The history, epidemiology and biology are reviewed. Some hypothesis about the pathogenesis of bullous tungiasis are suggested.

[Bullosis diabeticorum: ten cases report]

Bullosis diabeticorum is a rare characteristic complication of diabetes mellitus; it affects 0.5%of diabetics. Bullosis diabeticorum is a manifestation of complicate and longstanding diabetes mellitus. Of our study was to describe particularities of diabetes in patients suffering of this disease. We have led a retrospective study covering a 5 year-period [January 2001-December 2007] in the dermatology department of the Charles Nicolle's hospital in Tunisia. We selected for this study all cases of bullosis diabeticorum. During the studied period, 10 cases have been collected. They were in all cases about complicate and long-standing diabetes. Bullosis diabeticorum has a favourable outcome in all cases with symptomatic treatment. The different cases of bullosis diabeticorum reported in our series were associated to complicate diabetes mellitus what lets suggest that vascular deteriorations led to cutaneous fragility responsible for the skin cleavage

Effect of Excision of Avascular Bleb and Advancement of Adjacent Conjunctiva for Treatment of Hypotony

PURPOSE: To evaluate the efficacy of excision of avascular bleb and advancement of adjacent conjunctiva (EBAC) for treatment of hypotony after trabeculectomy with mitomycin C (MMC). METHODS: Fifteen patients (17 eyes) who received EBAC for correction of hypotony between September 1996 and October 2008 were reviewed retrospectively. The main outcomes were intraocular pressure (IOP) and postoperative complications. RESULTS: Hypotony (IOP <6 mmHg) of eight eyes (47.1%, seven patients) was caused by bleb perforation. Of these, two eyes (two patients) had a history of trauma. Hypotony appeared at 33.9+/-30.8 months, and EBAC was performed at 48.2+/-35.3 months after trabeculectomy with MMC. The mean follow-up period was 38.3+/-29.8 months. The qualified success rate of EBAC was 100% at 51 months after EBAC, and the complete success rate of EBAC was 76.5% at six months and 70.6% at 51 months, as determined by Kaplan-Meier analysis. Post-EBAC complications included blepharoptosis in four eyes (23.5%) and bleb perforation in one (5.9%). The blepharoptosis resolved within one month after EBAC in two patients. However, in the other patients, mild blepharoptosis remained at 17 and 22 months postoperatively. CONCLUSIONS: EBAC was found to be an effective method for treatment of hypotony after trabeculectomy with MMC, and postoperative blepharoptosis was a major complication.

Ceratopatia bolhosa: etiopatogênese e tratamento: [revisão] / Bullous keratopathy: etiopathogenesis and treatment: [review]

A ceratopatia bolhosa caracteriza-se pelo edema corneano estromal acompanhado de bolhas epiteliais e subepiteliais devido à perda de células e/ou alterações da junção endotelial. Nos casos mais avançados, ocorre espessamento do estroma e presença de fibrose subepitelial e vascularização corneana. Apresenta baixa de acuidade visual devido à diminuição da transparência da córnea e pode estar acompanhada de sensação de corpo estranho, lacrimejamento e dor devido as alterações epiteliais como a presença de bolhas íntegras ou rotas. Ceratite bolhosa é uma das principais causas de transplante de córnea em diferentes regiões e países. A principal etiologia é a perda de células endoteliais, principalmente após cirurgia de catarata e na distrofia endotelial de Fuchs. Sabe-se que atualmente há cerca de 20 milhões de pessoas com catarata no mundo, e esta complicação pode afetar 1 a 2 por cento das cirurgias de catarata. Este texto faz uma revisão sobre a etiopatogênese da ceratopatia bolhosa e sobre os tratamentos clínicos e cirúrgicos disponíveis para a doença.

Bullous keratopathy is characterized by corneal stromal edema with epithelial or subepithelial bullae due to cell loss and endothelial decompensation. In more advanced cases, subepithelial fibrosis, formation of a posterior collagenous layer or retrocorneal fibrous membrane, and corneal vascularization can occur. Decreased vision is present because the loss of corneal transparency with symptoms like tearing and pain caused by epithelial bullae that can rupture. Currently, bullous keratopathy is the most common indication for penetrating keratoplasty and regraft. The main etiology is the endothelial cell loss after ophthalmic surgeries as cataract surgery. Cataract affects approximately 20 million people worldwide, and this complication can occur in 1 to 2 percent of cataract surgeries. This study revised bullous keratopathy etiopathogenesis, clinical and surgical treatment available for this corneal disease.
