Hospitalizations and in-hospital mortality for inflammatory bowel disease in Brazil.

BACKGROUND: Inflammatory bowel disease (IBD) is associated with complications, frequent hospitalizations, surgery and death. The introduction of biologic drugs into the therapeutic arsenal in the last two decades, combined with an expansion of immunosuppressant therapy, has changed IBD management and may have altered the profile of hospitalizations and in-hospital mortality (IHM) due to IBD. AIM: To describe hospitalizations from 2008 to 2018 and to analyze IHM from 1998 to 2017 for IBD in Brazil. METHODS: This observational, retrospective, ecological study used secondary data on hospitalizations for IBD in Brazil for 2008-2018 to describe hospitalizations and for 1998-2017 to analyze IHM. Hospitalization data were obtained from the Hospital Information System of the Brazilian Unified Health System and population data from demographic censuses. The following variables were analyzed: Number of deaths and hospitalizations, length of hospital stay, financial costs of hospitalization, sex, age, ethnicity and type of hospital admission. RESULTS: There was a reduction in the number of IBD hospitalizations, from 6975 admissions in 1998 to 4113 in 2017 (trend: y = -0.1682x + 342.8; R2 = 0.8197; P < 0.0001). The hospitalization rate also decreased, from 3.60/100000 in 2000 to 2.17 in 2010. IHM rates varied during the 20-year period, between 2.06 in 2017 and 3.64 in 2007, and did not follow a linear trend (y = -0.0005049x + 2.617; R2 = 0,00006; P = 0.9741). IHM rates also varied between regions, increasing in all but the southeast, which showed a decreasing trend (y = -0.1122x + 4.427; R2 = 0,728; P < 0.0001). The Southeast region accounted for 44.29% of all hospitalizations. The Northeast region had the highest IHM rate (2.86 deaths/100 admissions), with an increasing trend (y = 0.1105x + 1.110; R2 = 0.6265; P < 0.0001), but the lowest hospitalization rate (1.15). The Midwest and South regions had the highest hospitalization rates (3.27 and 3.17, respectively). A higher IHM rate was observed for nonelective admissions (2.88), which accounted for 81% of IBD hospitalizations. The total cost of IBD hospitalizations in 2017 exhibited an increase of 37.5% compared to 2008. CONCLUSION: There has been a notable reduction in the number of hospitalizations for IBD in Brazil over 20 years. IHM rates varied and did not follow a linear trend.

Mandibular Reconstruction in a Patient With Rosai-Dorfman Disease.

OBJECTIVE: The Rosai-Dorfman disease (RDD) is a rare disorder known as sinus histiocytosis with massive lymphadenopathy which affects other organs besides the lymphatic nodes. The most frequent clinical presentation is the skin involvement, but the most serious one is when the central nervous system is compromised. There are not clinical cases in the literature reporting the mandibular involvement and its management. The aim of this study is to report the case of a patient with this disease, her treatment, and her follow-up. STUDY: A 32-year-old woman with RDD, who underwent a right mandibulectomy to treat osteomyelitis, and who suffered hemolytic anemia, lymphoproliferative syndrome, and bacterial meningitis by meningococcus treated successfully, is presented. She also had osteosynthesis plate exposure in 3 occasions. The authors performed a mandibular reconstruction with a fibula free flap. Vertical osteogenic distraction was done to improve the vertical height of the bone for osteointegrated implants and later oral rehabilitation. METHODS: The senior authors performed mandibular reconstruction with a fibula free flap. Vertical osteogenic distraction was performed to improve the vertical height of the bone for osteointegrated implants and later oral rehabilitation. The patient achieved adequate function with a good mandibular height and occlusion. RESULTS: The patient had a follow-up of 6 months. She is highly satisfied with her result. Preoperative and postoperative photos are shown. DISCUSSION: In this rare case, the authors show the difficulties when treating this disease. The follow-up of the patient showed a successful reconstruction with good functional results.

Los colgajos de perforantes se han constituido en el escalón reconstructivo de mayor refinamiento quirúrgico por sus beneficios al dejar mínima morbilidad en las áreas donantes y permitir el tallado de los tejidos más precisos a los defectos a reconstruir, permitiendo al mismo tiempo la transferencia de varios tipos de tejidos, constituyéndose así en una herramienta versátil para casos complejos, con defectos tridimensionales y necesidades tisulares específicas. El presente artículo realiza una revisión de los aspectos clínicos, así como la presentación de pacientes manejados con esta opción que dentro del campo de la microcirugía reconstructiva se posiciona como la primera elección al contemplar las diferentes posibilidades de tratamiento.

Perforator flaps have turned into the reconstructive step with the highest surgical refinement because of its benefits by limiting the donor site morbidity and allowing more accurate tissue graving in the defects to be reconstructed while allowing the transference of several types of tissues, thus becoming a versatile tool for complex cases with tridimensional defects and specific tissue needs. This article reviews the clinical features as well as the presentation of patients managed through this option, which, in the field of reconstructive microsurgery, has been positioned as the leading election when the different possibilities of treatment are considered.

Os retalhos de perfurantes constituemse no degrau reconstrutivo de maior refinamento cirúrgico por seus benefícios ao deixar mínima morbilidade nas áreas doadoras e permitir esculpir os tecidos de forma mais precisa no momento de corrigir defeitos e reconstruir, permitindo ao mesmo tempo a transferência de vários tipos de tecidos, constituindose assim em uma ferramenta versátil para casos complexos, com defeitos tridimensionais e necessidades tissulares específicas. O presente artigo faz uma revisão dos aspectos clínicos, bem como a apresentação de pacientes tratados com esta opção que dentro do campo da microcirurgia reconstrutiva se posiciona como a primeira escolha ao considerar as diferentes possibilidades de tratamento.
