RESUMO Introdução: a substituição esofágica em crianças está indicada quando não é possível manter o esôfago nativo, o que inclui principalmente pacientes com atresia esofágica e estenose cáustica esofágica. O objetivo deste trabalho é relatar a experiência de um serviço universitário com duas técnicas de substituição esofágica, a transposição gástrica e a esofagocoloplastia. Métodos: Estudo retrospectivo baseado na revisão de arquivos hospitalares. A população do estudo foi de 30 pacientes com idade entre 6 meses e quatorze anos, submetidos à substituição esofágica, no período de 1995 a 2022, no Hospital de Clínicas da Universidade Estadual de Campinas. Os dados analisados foram idade, sexo, doença de base, aspectos técnicos, complicações e resultados a longo prazo. Resultados: As doenças de base mais comuns foram atresia de esôfago (73,33%) e estenose cáustica (26,67%). Vinte e um pacientes foram submetidos à transposição gástrica (70%) e nove à esofagocoloplastia (30%). A complicação pós-operatória mais frequente foi fístula da anastomose proximal, que ocorreu em 14 pacientes. A maioria dos pacientes com fístula teve recuperação espontânea. Houve três mortes no total. Dos 27 sobreviventes, 24 conseguem se alimentar exclusivamente por via oral. Conclusão: A substituição esofágica em crianças é um procedimento com alta morbimortalidade. Esofagocoloplastia e transposição gástrica têm resultados e complicações semelhantes, com exceção de fístulas da anastomose proximal, que são em geral auto-resolutivas e mais comuns na esofagocoloplastia. A escolha da melhor técnica cirúrgica deve ser individualizada, sendo que ambas as técnicas oferecem a capacidade de alimentação via oral a curto ou médio prazo.

ABSTRACT Introduction: esophageal replacement in children is indicated when it is impossible to maintain the native esophagus, which in the pediatric population includes patients with esophageal atresia and esophageal caustic stenosis. The objective of this communication is to report the experience of a university service with two techniques of esophageal replacement. Methods: this is a retrospective study based on the revision of hospital files. The study population consisted of patients who underwent esophageal replacement from 1995 to 2022, at the Hospital de Clínicas of the State University of Campinas. The analyzed data were age, sex, underlying disease, technical aspects, complications, and long-term results. Results: during the study period, 30 patients underwent esophageal replacement. The most common underlying diseases were esophageal atresia (73.33%) and caustic stenosis (26.67%). Twenty-one patients underwent gastric transposition (70%), and nine underwent esophagocoloplasty (30%). The most frequent postoperative complication was fistula of the proximal anastomosis, which occurred in 14 patients. Most of the patients with fistulas had a spontaneous recovery. There were three deaths. Of the 27 survivors, 24 can feed exclusively by mouth. Conclusion: esophageal replacement in children is a procedure with high morbidity and mortality. Esophagocoloplasty and gastric transposition have similar results and complications, with the exception of proximal anastomotic fistulas, which are generally self-resolving and are more common in esophagocoloplasty. The choice of the best surgical technique must be individualized according to the patients characteristics and the surgeons experience, as both techniques offer the ability to feed orally in the short or medium term.

ABSTRACT BACKGROUND: Bishop-Koop ileostomy has been widely used in pediatric patients with the intention of including as much bowel as possible in the intestinal transit early in the management of children with meconium ileus and intestinal atresia. In recent years, we have been using it as an alternative to test the distal bowel function before closure of a previously constructed ostomy in selected children with questionable distal bowel motility. AIMS: The aim of this study was to present our experience with this alternative use of the Bishop-Koop ostomy. METHODS: This is a cross-sectional retrospective review of hospital records, combined with a comprehensive literature review. RESULTS: Seven children were included: five had suspected aganglionosis, one had gastroschisis complicated with ileal atresia, and one had a colonic stricture secondary to necrotizing enterocolitis. In this short series of patients, motility of the distal bowel was correctly assessed in six patients and partially correctly assessed in one patient. One patient did not pass stools per anus after the Bishop-Koop, and he was later confirmed to have Hirschsprung disease. Four patients resumed normal evacuation pattern after closure of the Bishop-Koop. One patient had a Bishop-Koop colostomy because of recurrent enterocolitis after a transanal pull-through. Although he evacuated normally while having the colostomy, the diarrhea recurred after the ostomy was closed. An additional patient, with a severe behavioral problem, did not evacuate per anus after her colostomy was transformed in a Bishop-Koop-type ostomy, despite the apparent presence of normal ganglia in the bowel wall. CONCLUSIONS: Data from the present series allow us to affirm that Bishop-Koop-type ostomy is a safe and efficient procedure that can be used to assess distal bowel function before a definitive transit reconstruction, in children with uncertain motility issues.

RESUMO RACIONAL: A ileostomia Bishop-Koop foi amplamente utilizada em pacientes pediátricos com a intenção de incluir o máximo de intestino possível no trânsito intestinal no manejo inicial de recém-nascidos com íleo meconial e atresia intestinal. Nos últimos anos, temos usado-a como alternativa para testar a função intestinal distal antes do fechamento de uma ostomia, em algumas crianças com motilidade intestinal distal questionável. OBJETIVOS: Apresentar nossa experiência com este uso alternativo da ostomia Bishop-Koop. MÉTODOS: Revisão retrospectiva dos registros hospitalares, combinada com uma revisão abrangente da literatura. RESULTADOS: Sete crianças foram incluídas: cinco tinham suspeita de aganglionose, uma tinha gastrosquise complicada com atresia ileal e uma tinha estenose de colon secundária à NEC. Nesta pequena série de pacientes, a motilidade do intestino distal foi corretamente avaliada em 6 pacientes e parcialmente avaliada em um. Um paciente não evacuou por ânus após o Bishop-Koop e mais tarde foi confirmado que ele tinha doença de Hirschsprung. Seis pacientes retomaram o padrão normal de evacuação após o fechamento do Bishop-Koop. Um paciente que fez uma colostomia Bishop-Koop por causa de enterocolite recorrente após um abaixamento transanal, recidivou a enterocolite após o fechamento definitivo. CONCLUSÕES: A ostomia tipo Bishop-Koop é um procedimento seguro e eficaz que pode ser utilizado para avaliar a função intestinal distal antes de uma reconstrução definitiva do trânsito em crianças com problemas de motilidade intestinal.

ABSTRACT Introduction: in Brazil, trauma is responsible for 40% of deaths in the age group between 5 and 9 years old, and 18% between 1 and 4 years, and bleeding is the leading cause of preventable death in the traumatized child. Conservative management of blunt abdominal trauma with solid organs injury - started in the 60s - is the current world trend, with studies showing survival rates above 90%. The objective was to assess the efficacy and safety of conservative treatment in children with blunt abdominal trauma treated at the Clinical Hospital of the University of Campinas, in the last five years. Methods: retrospective analysis of medical records of patients classified by levels of injury severity, in 27 children. Results: only one child underwent surgery for initial failure of conservative treatment (persistent hemodynamic instability), resulting in a 96% overall success rate of the conservative treatment. Five other children (22%) developed late complications that required elective surgery: a bladder injury, two cases of infected perirenal collections (secondary to injury of renal collecting system), a pancreatic pseudocyst and a splenic cyst. Resolution of the complications was attained in all children, with anatomical and functional preservation of the affected organ. There were no deaths in this series. Conclusion: the conservative initial approach in the treatment of blunt abdominal trauma was effective and safe with high resolution and low rate of complications leading to a high preservation rate of the affected organs. Level of evidence III - prognostic and therapeutic study.

RESUMO Introdução: no Brasil, o trauma é responsável por 40% dos óbitos na faixa etária entre 5 e 9 anos, e 18% entre 1 e 4 anos, e o sangramento é a principal causa de prevenção morte na criança traumatizada. O manejo conservador de trauma abdominal contuso com lesão de órgãos sólidos - iniciado na década de 60 - é a tendência mundial atual, com estudos mostrando taxas de sobrevivência acima de 90%. O objetivo do presente trabalho foi avaliar a eficácia e segurança do tratamento conservador em crianças com trauma abdominal contuso tratado no Hospital das Clínicas da Universidade de Campinas, nos últimos cinco anos. Métodos: análise retrospectiva de prontuários de pacientes classificados por níveis de gravidade da lesão, em 27 crianças. Resultados: apenas uma criança foi submetida a cirurgia por falha inicial do tratamento conservador (instabilidade hemodinâmica persistente), resultando em uma taxa de sucesso global de 96% do tratamento conservador inicial. Outras cinco crianças (22%) desenvolveram complicações tardias que exigiram cirurgias eletivas: lesão na bexiga, dois casos de coleção perirenal infectada (secundária à lesão de sistema de coleta renal), um pseudocisto pancreático e um cisto esplênico. Resolução da complicação foi atingida em todas as crianças, com preservação anatômica e funcional do órgão afetado. Não houve mortes nesta série. Conclusão: a abordagem inicial conservadora no tratamento de trauma abdominal contundente foi eficaz e segura com alta resolução e baixa taxa de complicações levando a uma alta taxa de preservação dos órgãos afetados.

Resumo Objetivo Comparar a evolução clínica em crianças com constipação intestinal funcional refratária sob diferentes regimes terapêuticos: laxativos orais e enemas anterógrados via apendicostomia ou tratamento clínico com laxativos orais e enemas via retal. Métodos Análise de uma série de 28 pacientes, 7,9 anos (2,4-11), acompanhados em ambulatório terciário. Constipação intestinal funcional refratária foi definida como manutenção da incontinência fecal retentiva, em terapia consensual, por pelo menos 12 meses. Após diagnóstico de refratariedade, era proposta apendicostomia. Dezessete pacientes realizaram o procedimento cirúrgico. Desfechos: 1. Manutenção de incontinência fecal retentiva em uso de enemas; 2. Controle da incontinência fecal retentiva em uso de enemas; e 3. Controle da incontinência fecal retentiva, evacuações espontâneas, sem necessidade de enemas. Resultados Seis e 12 meses após opção terapêutica, controle da incontinência fecal retentiva foi observado apenas nos pacientes operados, 11/17 e 14/17, p = 0,001 e p = 0,001. Aos 24 meses, controle da incontinência fecal retentiva também mais frequente nos operados 13/17 versus 3/11 tratamento clínico, p = 0,005. Na avaliação final, medianas de tempo de seguimento: 2,6 e 3 anos (operados versus tratamento clínico, p = 0,40), um paciente em cada grupo abandonou o seguimento e 9/16 operados apresentavam evacuações espontâneas versus 3/10 no tratamento clínico, p = 0,043. Complicações cirúrgicas, 42 episódios, acometeram 14/17 pacientes. Conclusão A apendicostomia, embora associada a elevada frequência de complicações, controlou a incontinência fecal retentiva de maneira mais precoce e frequente do que o tratamento clínico. A escolha de um dos métodos deverá caber à família, após adequada informação sobre riscos e benefícios de cada alternativa.

Abstract Objective: To compare the clinical evolution in patients with refractory functional constipation undergoing different therapeutic regimens: oral laxatives and antegrade enemas via appendicostomy or clinical treatment with oral laxatives and rectal enemas. Methods: Analysis of a series of 28 patients with a mean age of 7.9 years (2.4-11), followed-up in a tertiary outpatient clinic. Refractory functional constipation was defined as continuous retentive fecal incontinence after at least a 12-month period of consensus therapy. After the diagnosis of refractory condition, appendicostomy was proposed and performed in 17 patients. Outcomes: (1) persistence of retentive fecal incontinence despite the use of enemas, (2) control of retentive fecal incontinence with enemas, and (3) control of retentive fecal incontinence, spontaneous evacuations, with no need for enemas. Results: Six and 12 months after the therapeutic option, control of retentive fecal incontinence was observed only in patients who underwent surgery, 11/17 and 14/17, p = 0.001 and p = 0.001, respectively. At 24 months, control of retentive fecal incontinence was also more frequent in operated patients: 13/17 versus 3/11 with clinical treatment, p = 0.005. In the final evaluation, the median follow-up times were 2.6 and 3 years (operated vs. clinical treatment, p = 0.40); one patient in each group was lost to follow-up and 9/16 operated patients had spontaneous bowel movements vs. 3/10 in the clinical treatment group, p = 0.043. Surgical complications, totaling 42 episodes, were observed 14/17 patients. Conclusion: Appendicostomy, although associated with a high frequency of complications, controlled retentive fecal incontinence earlier and more frequently than clinical treatment. The choice of one of the methods should be made by the family, after adequate information about the risks and benefits of each alternative.

SUMMARY A gonadal tumor was diagnosed in the first months of life in a patient with genital ambiguity, a 45,X/46,XY karyotype, and mixed gonadal dysgenesis. Gonadal biopsies at the age of 3 months revealed dysgenetic testes and a gonadoblastoma on the right testis. Even though gonadal tumors are rare in childhood, this case indicates that prophylactic removal of dysgenetic gonads should be performed as early as possible, especially when the female sex is assigned to a patient with a Y-chromosome sequence.

Resumo Objetivo: Descrever o caso de um lactente portador de doença de Hirschsprung na forma aganglionose colônica total que, após a ressecção cirúrgica do segmento agangliônico, manteve quadro irreversível de obstrução intestinal funcional; discutir as dificuldades no manejo dessa forma da aganglionose congênita e apontar um mecanismo patogenético plausível para o caso. Descrição do caso: O diagnóstico de doença de Hirschsprung na forma aganglionose colônica total foi definido em lactente aos dois meses de vida, após episódio de enterocolite, choque hipovolêmico e desnutrição grave. Após ressecção colônica, o paciente não recuperou a função motora intestinal que possibilitasse a alimentação via enteral. O exame do íleo remanescente pós-operatório mostrou presença de plexos ganglionares e redução numérica das células intersticiais de Cajal em segmentos proximais do intestino. Aos 12 meses de vida, o paciente mantém-se dependente de nutrição parenteral total. Comentários: A doença de Hirschsprung na forma aganglionose colônica total tem particularidades clínico-cirúrgicas que a diferenciam das formas clássicas e dificultam o diagnóstico e o manejo clínico-cirúrgico. A evolução pós-operatória pode associar-se à morbidade permanente decorrente de dismotilidade intestinal. A redução numérica ou as alterações das conexões neurais das células intersticiais de Cajal podem representar uma possível base fisiopatológica para a condição.

Abstract Objective: To describe the case of an infant with Hirschsprung's disease presenting as total colonic aganglionosis, which, after surgical resection of the aganglionic segment persisted with irreversible functional intestinal obstruction; discuss the difficulties in managing this form of congenital aganglionosis and discuss a plausible pathogenetic mechanism for this case. Case description: The diagnosis of Hirschsprung's disease presenting as total colonic aganglionosis was established in a two-month-old infant, after an episode of enterocolitis, hypovolemic shock and severe malnutrition. After colonic resection, the patient did not recover intestinal motor function that would allow enteral feeding. Postoperative examination of remnant ileum showed the presence of ganglionic plexus and a reduced number of interstitial cells of Cajal in the proximal bowel segments. At 12 months, the patient remains dependent on total parenteral nutrition. Comments: Hirschsprung's disease presenting as total colonic aganglionosis has clinical and surgical characteristics that differentiate it from the classic forms, complicating the diagnosis and the clinical and surgical management. The postoperative course may be associated with permanent morbidity due to intestinal dysmotility. The numerical reduction or alteration of neural connections in the interstitial cells of Cajal may represent a possible physiopathological basis for the condition.

PURPOSE: To assess the efficacy of an adjustable inspiratory occlusion valve in experimental bronchopleural fistula during mechanical ventilation.METHODS:We studied six mechanically ventilated pigs in a surgically created, reproducible model of bronchopleural fistula managed with mechanical ventilation and water-sealed thoracic drainage. An adjustable inspiratory occlusion valve was placed between the thoracic drain and the endotracheal tube. Hemodynamic data, capnography and blood gases were recorded before and after the creation of the bronchopleural fistula as well as after every adjustment of the inspiratory occlusion valve.RESULTS:When compared with the standard water-sealed drainage treatment, the use of an adjustable inspiratory occlusion valve improved the alveolar tidal volume and reduced bronchopleural air leak (p<0.001), without hemodynamic compromise when compared with conventional water sealed drainage.CONCLUSION: The use of an adjustable inspiratory occlusion valve improved the alveolar tidal volume, reduced alveolar leak, in an experimental reproducible model of bronchopleural fistula, without causing any hemodynamic derangements when compared with conventional water sealed drainage.

OBJETIVO: Avaliar as características clínicas e os padrões de trânsito intestinal em crianças brasileiras com constipação refratária.MÉTODOS: De 2010 a 2013, 79 pacientes constipados receberam acompanhamento em um hospital terciário. Desses pacientes, 28 (entre 8-14 anos) foram identificados como terapia refratária a convencional e passaram por um método visual simplificado de estudo nuclear do trânsito intestinal, com ingestão de uma refeição líquida contendo 9,25 MBq/Kg de fitato-99mTc. Imagens estáticas abdominais foram tiradas imediatamente e em duas, seis, 24, 30 e 48 horas após a ingestão para uma análise qualitativa da progressão do marcador radioativo pelo cólon.RESULTADOS: Foram encontrados dois padrões de trânsito intestinal: trânsito intestinal lento (STC, n = 14), quando as imagens de 48 horas mostraram que grande parte do marcador permaneceu no cólon proximal e transversal; e retenção distal (DR, n = 14), quando, após 30 horas, o radioisótopo havia passado o cólon transverso e estava retido no retossigmoide até 48 horas. O grupo STC e o grupo DR incluíram, respectivamente, nove e 10 meninos; idade média no momento do NTS: 11 e 10 anos, p = 0,207; duração média de constipação: sete e seis anos, p = 0,599. Sintomas de constipação durante o primeiro ano de idade (p = 0,04) e relatos de fezes moles (p = 0,02) foram mais comuns em pacientes com STC. Observou-se impactação fecal abdominal palpável apenas no grupo DR. A apendicostomia para enema anterógrado para continência foi bem-sucedida em 4/12 (305) pacientes com STC (acompanhamento médio: 2,4 anos).CONCLUSÃO: O estudo nuclear do trânsito diferenciou dois padrões de dismotilidade intestinal e foi útil para orientar pacientes refratários a terapias específicas.

OBJECTIVE: The aim of this study was to assess clinical features and colonic transit patterns in Brazilian children with refractory constipation.METHODS: From 2010 to 2013, 79 constipated patients received follow-up care in a tertiary hospital. Of these patients, 28 (aged 8-14 years) were refractory to conventional therapy and underwent a simplified visual method of nuclear colonic transit study, by ingestion of a liquid meal containing 9.25 MBq/kg of 99mTc-phytate. Abdominal static images were taken immediately and at two, six, 24, 30, and 48 h after ingestion for qualitative analysis of the radio marker progression through the colon.RESULTS: Two patterns of colonic transit were found: slow colonic transit (SCT,n = 14), when images at 48 h showed a larger part of the tracer remained in proximal and transverse colon, and distal retention (DR, n = 14), when after 30 h, the radio isotope passed the transverse colon and was retained in the rectosigmoid up to 48 h. The SCT and DR group included, respectively, nine and ten males; median ages in the nuclear study of 11 and 10 years, p = 0.207; median duration of constipation of seven and six years, p = 0.599. Constipation appearing during first year age (p = 0.04) and report of soft stools (p = 0.02) were more common in SCT patients. Palpable abdominal fecal impaction was found only in DR group. Appendicostomy for antegrade continence enema was successful in 4/12 (30%) of SCT patients (median follow-up: 2.4 years).CONCLUSION: Nuclear transit study distinguished two colonic dysmotility patterns and was useful for guiding refractory patients to specific therapies.

PURPOSE:To investigate the hemodynamic and ventilatory changes associated with the creation of an experimental bronchopleural fistula (BPF) treated by mechanical ventilation and thoracic drainage with or without a water seal.METHODS :Six large white pigs weighing 25 kg each which, after general anesthesia, underwent endotracheal intubation (6mm), and mechanically ventilation. Through a left thoracotomy, a resection of the lingula was performed in order to create a BPF with an output exceeding 50% of the inspired volume. The chest cavity was closed and drained into the water sealed system for initial observation of the high output BPF.RESULTS:Significant reduction in BPF output and PaCO2 was related after insertion of a water-sealed thoracic drain, p< 0.05.CONCLUSION: Insertion of a water-sealed thoracic drain resulted in reduction in bronchopleural fistula output and better CO2 clearance without any drop in cardiac output or significant changes in mean arterial pressure.

Flexible endoscopes are fundamental in various medical specialities; in general they are heat-sensitive, semi-critical, and subject to high level disinfection. Glutaraldehyde is largely used for this purpose, due to its high compatibility and low-cost. However, its tolerance of mycobacteria and occupational toxicity lead to pressure being applied for the adoption of alternative germicides. A systematic review was undertaken aiming to seek evidence regarding the effectiveness, toxicity and potential harm caused to the endoscopes by those germicides which are alternative to glutaraldehyde and which are available on the market in Brazil. A total of 822 publications was identified in 13 electronic databases, between 2008 and 2013. Of these, 23 studies were selected, considering the best quality of evidence available. The publications point to the superiority of peracetic acid and of orthophthaldehyde regarding efficacy in high level disinfection. Only orthophthaldehyde presented an adverse event clearly related to its use. There is insufficient evidence to assert that any of these germicides has greater potential for harm to the equipment.

Fundamentales en diversas especialidades médicas, los endoscopios flexibles son, normalmente, termosensibles, semicríticos y sometidos a la desinfección de alto nivel. El glutaraldehído es muy utilizado para esa finalidad, en razón de la gran compatibilidad y bajo custo, pero la tolerancia de microbacterias y el hecho de ser o no tóxico de modo ocupacional presionan por la adopción de germicidas alternativos. Fue realizada revisión sistemática con el objetivo de buscar evidencias sobre la efectividad, toxicidad y potenciales daños causados a los endoscopios por los germicidas alternativos al glutaraldehído, disponibles en el mercado brasileño. Fueron identificadas, en 13 bases electrónicas, 822 publicaciones, entre 2008 y 2013. De estas, fueron seleccionados 23 estudios, considerando la mejor cualidad de evidencia disponible. Las publicaciones apuntaron para la superioridad del ácido peracético y del ortoftalaldehído cuanto a la eficacia en la desinfección de alto nivel. Solamente el ortoftalaldehído presentó evento adverso claramente relacionado a su utilización. No hay evidencias suficientes para afirmar que algun de estes germicidas presenta mayor potencial de daños a los equipos.

OBJECTIVE: Here, we describe our experience with different therapeutic modalities used to treat cystic lymphangiomas in children in our hospital, including single therapy with OK-432, bleomycin and surgery, and a combination of the three modalities. METHODS: We performed a retrospective, cross-sectional study including patients treated from 1998 to 2011. The effects on macrocystic lymphangiomas and adverse reactions were evaluated. Twenty-nine children with cystic lymphangiomas without any previous treatment were included. Under general anesthesia, patients given sclerosing agents underwent puncture of the lesion (guided by ultrasound when necessary) and complete aspiration of the intralesional liquid. The patients were evaluated with ultrasound and clinical examinations for a maximum follow-up time of 4 years. RESULTS: The proportions of patients considered cured after the first therapeutic approach were 44% in the surgery group, 29% in the bleomycin group and 31% in the OK-432 group. These proportions were not significantly different. Sequential treatment increased the rates of curative results to 71%, 74% and 44%, respectively, after the final treatment, which in our case was approximately 1.5 applications per patient. CONCLUSION: The results of this study indicate that most patients with cystic lymphangiomas do not show complete resolution after the initial therapy, regardless of whether the therapy is surgical or involves the use of sclerosing agents. To achieve complete resolution of the lesions, either multiple operations or a combination of surgery and sclerotherapy must be used and should be tailored to the characteristics of each patient.

OBJECTIVES AND INTRODUCTION: Gastroschisis is a congenital abdominal wall defect with increasing occurrence worldwide over the past 20-30 years. Our aim was to analyze the morbidity of newborns after gastroschisis closure, with emphasis on metabolic and hydroelectrolyte disturbances in patients at three tertiary university centers. METHODS: From January 2003 to June 2009, the following patient data were collected retrospectively: (A) Background maternal and neonatal data: maternal age, prenatal diagnosis, type of delivery, Apgar scores, birth weight, gestational age and sex; (B) Surgical modalities: primary or staged closure; and (C) Hospital course: levels of serum sodium and levels of serum albumin in the two first postoperative days, number of ventilation days, other postoperative variables and survival. Statistical analyses were used to examine the associations between some variables. RESULTS: 163 newborns were included in the study. Primary closure of the abdominal defect was performed in 111 cases (68.1%). The mean serum sodium level was 127.4¡6.7 mEq/L, and the mean serum albumin level was 2.35¡0.5 g/dL. Among the correlations between variables, it was verified that hyponatremia and hypoalbuminemia correlated with the number of days on the ventilator but not with the number of days on total parenteral nutrition (TPN); mortality rate correlated with infection. The final survival rate was 85.9%. CONCLUSION: In newborns with gastroschisis, more aggressive attention to hyponatremia and hypoalbuminemia would improve the outcome.

INTRODUCTION: Correction of gastroschisis can be accomplished by primary or staged closure. There is, however, no consensus regarding the best approach or criteria to favor one method over the other has been established. OBJECTIVE: To compare the outcome of primary and staged closure in newborns with gastroschisis using intravesical pressure (IVP) as the decision criterion. PATIENTS & METHODS: We prospectively analyzed 45 newborns with gastroschisis. An IVP with a threshold of 20 cm H2O was used to indicate primary or staged closure, and the outcomes between the two methods were compared. RESULTS AND DISCUSSION: Newborns in whom primary closure was feasible were born at a lower gestational age. There was no significant difference in the frequency of complications, time to begin oral feeding, length of parenteral nutrition or length of hospital stay. Compared with previous reports, our data showed higher rates of prenatal diagnosis and cesarean delivery, a lower average birth weight, a higher rate of small gestational age babies and a more frequent association with intestinal atresia. Conversely, our data showed a lower rate of postoperative necrotizing enterocolitis and a lower average length of hospital stay. CONCLUSION: No significant difference was observed in the outcome of newborns who underwent primary closure or staged closure of gastroschisis when using an IVP below 20 cm H2O as the criterion for primary closure.

OBJETIVO: Avaliar a evolução clínica e comparar a eficácia do tratamento fisioterapêutico intensivo ou mínimo, em neonatos e lactentes com torcicolo congênito. MÉTODOS: Foram atendidas no Ambulatório de Fisioterapia e Cirurgia Pediátrica do Hospital de Clínicas da Universidade Estadual de Campinas 47 crianças com torcicolo congênito. Analisaram-se, retrospectivamente, antecedentes maternos, neonatais, apresentação clínica e tratamento fisioterapêutico, classificado de acordo com a freqüência das sessões. O tratamento intensivo foi definido como sessões de fisioterapia realizadas pelo fisioterapeuta no ambulatório, acrescidas de exercícios diários realizados pelos pais em domicílio. O tratamento mínimo foi considerado quando apenas o fisioterapeuta realizava as sessões semanalmente no ambulatório, sem a participação dos pais. RESULTADOS: Quanto às características demográficas da população, observou-se: idade média materna=26 anos; parto normal=40 (85%); mães primigestas=35 (75%); idade média ao diagnóstico=50 dias. A presença de nódulo intramuscular foi notada em 46 (98%) pacientes. As seguintes doenças estiveram associadas: luxação congênita de quadril igual=4 (8%); fratura de clavícula=2 (4%); pé torto congênito=1 (2%). O tratamento intensivo foi realizado em 34 (72%) pacientes e a cura observada em 100%, após 74 dias, em média. O tratamento mínimo foi aplicado em 13 (28%) pacientes e a cura observada em dez (77%), tratados em média por 130 dias. CONCLUSÕES: O torcicolo congênito apresentou evolução clínica favorável em ambos os grupos. O tratamento intensivo propiciou maior índice de cura em menor tempo de tratamento.

OBJECTIVE: To evaluate the clinical course and to compare the effectiveness of physiotherapeutic treatment performed daily or once a week in newborns and infants with congenital torticollis. METHODS: 47 patients with congenital torticollis were assisted at the Physiotherapy and Pediatric Surgery Services of the Clinical Hospital of Campinas University. The following data were retrospectively collected: maternal and neonatal history, clinical presentation and physiotherapeutic treatment classified according to the frequency of the exercises. Intensive treatment was defined as sessions performed at the daycare clinic by the physiotherapist plus daily sessions performed by parents at home. Minimal treatment was defined as weekly sessions performed only by the physiotherapist at the daycare clinic, without participation of the parents. RESULTS: The demographic characteristics of the studied patients were: mean maternal age=26 years; first gestation=35 (75%); vaginal delivery=40 (85%); mean age at diagnosis =50 days. A sternomastoid nodule was felt seen in 46 (98%) patients. Diseases associated with congenital torticollis were: congenital hip dislocation=4 (8%); fracture of clavicles=2 (4%); and club feet=1 (2%). Intensive treatment was performed in 34 (72%) patients for an average of 74 days and the cure was achieved in 100%. Minimal treatment was performed in 13 (28%) for an average of 130 days and ten (77%) patients achieved cure. CONCLUSIONS: Congenital torticollis had favorable outcome in both groups. The intensive treatment was followed by higher rates of cure in smaller period of time.
