RESUMO

PURPOSE: To compare the intraoperative and surgical outcomes of normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs), hypertensive PPGLs and non-PPGL adrenal lesions. METHODS: This a retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. A control group of histologically confirmed adrenocortical adenomas (non-PPGL group) was selected to compare intraoperative and surgical outcomes with of the normotensive PPGLs. RESULTS: Two hundred and ninety-six surgeries performed in 289 patients with PPGLs were included. Before surgery, 209 patients were classified as hypertensive PPGLs (70.6%) and 87 as normotensive PPGLs. A higher proportion of normotensive PPGLs than hypertensive PPGLs did not receive alpha presurgical blockade (P = 0.009). When we only considered those patients who received presurgical alpha blockers (200 hypertensive PPGLs and 76 normotensive PPGLs), hypertensive PPGLs had a threefold higher risk of intraoperative hypertensive crisis (OR 3.0 [95% 1.3-7.0]) and of hypotensive episodes (OR 2.9 [95% CI 1.2-6.7]) than normotensive PPGLs. When we compared normotensive PPGLs (n = 76) and non-PPGLs (n = 58), normotensive PPGLs had a fivefold higher risk of intraoperative complications (OR 5.3 [95% CI 1.9-14.9]) and a six times higher risk of postoperative complications (OR 6.1 [95% CI 1.7-21.6]) than non-PPGLs. CONCLUSION: Although the risk of intraoperative hypertensive and hypotensive episodes in normotensive PPGLs is significantly lower than in hypertensive PPGLs, normotensive PPGLs have a greater risk of intraoperative and postoperative complications than non-PPGL adrenal lesions. Therefore, it is recommended to follow the standard of care for presurgical and anesthetic management of PPGLs also in normotensive PPGLs.

RESUMO

INTRODUCTION: Bartter syndrome (BS) is a rare inherited tubulopathy that has two presentation forms, the first one is a severe form of antenatal onset (neonatal Bartter) and the second one is a later on set form during the first years of life (classic Bartter). In the antenatal form, it manifests with fetal polyuria, polyhydramnios of early and severe onset, premature delivery, and intrauterine growth restriction. In the postnatal stage, it presents recurrent episodes of dehydration and electrolyte im balance that can compromise the survival of the patient. OBJECTIVE: To report a clinical case of neo natal BS and a review of the literature. CLINICAL CASE: Premature newborn of 35 weeks of gestation with history of severe polyhydramnios diagnosed at 27 weeks of gestation, without apparent cause. From birth, the patient presented polyuria and hypokalemic metabolic alkalosis making a diagnosis of Neonatal Bartter Syndrome in the first week of life. Laboratory tests confirmed urinary electrolyte losses. The patient was treated with strict water balance and sodium and potassium supplementa tion, achieving weight and electrolyte imbalance stabilization. The patient remains in control in the nephrology unit, with potassium gluconate and sodium chloride supplementation. At the fourth month, ibuprofen was added as part of treatment. At the seventh month of life, renal ultrasound showed nephrocalcinosis. At one year of life, profound sensorineural hearing loss was observed re quiring a cochlear implant. CONCLUSION: The presence of severe polyhydramnios of early onset with no identified cause should lead to suspicion of neonatal BS which even when infrequent determines severe hydroelectrolytic alterations and should be treated early.

RESUMO

INTRODUCCIÓN: Síndrome de Bartter (SB) es una tubulopatía hereditaria, poco frecuente que tiene dos formas de presentación, forma grave de inicio antenatal (Bartter neonatal) y forma de aparición más tardía (Bartter clásico). En su forma antenatal se manifiesta con poliuria fetal, polihidroamnios de inicio precoz y severo, parto prematuro secundario y restricción de crecimiento intrauterino. La etapa postnatal presenta episodios recurrentes de deshidratación y desbalance electrolítico que pue den comprometer la sobrevida del paciente. OBJETIVO: Comunicar un caso de SB neonatal y presentar una revisión de la literatura en esta patología. CASO CLÍNICO: Prematuro 35 semanas, con antecedente de severo polihidroamnios diagnosticado a las 27 semanas de gestación, sin causa aparente. Desde su nacimiento evolucionó con poliuria y alcalosis metabólica hipokalémica haciendo plantear, en primera semana de vida, diagnóstico de Síndrome de Bartter neonatal. El laboratorio confirmó per didas urinarias de electrólitos. Fue manejado con balance hídrico estricto y suplementación de sodio y potasio, logrando estabilizar peso y desbalance electrolítico. Se mantiene en control nefrológico, con suplementación de gluconato de potasio y cloruro de sodio. Se agregó ibuprofeno al cuarto mes como parte del tratamiento. Al séptimo mes de vida, ecografía renal demostró nefrocalcinosis. Al año de vida se evidenció hipoacusia sensorioneural profunda requiriendo implante coclear. CONCLUSIÓN: Presencia de polihidroamnios severo de aparición temprana sin causa identificada debe hacer sospechar SB, que aun siendo infrecuente determina graves alteraciones hidroelectrolíticas y debe ser iniciado su tratamiento precozmente.

RESUMO

OBJECTIVES: To examine the relative length of the patient and primary care intervals in symptomatic oral cancer. DESIGN: Quantitative systematic review. SEARCH STRATEGY: Oral cancer OR oral squamous cell carcinoma OR oropharyngeal cancer AND time interval OR diagnostic delay. SETTING: Primary and secondary care. PARTICIPANTS: Oral and oropharyngeal cancer patients. MAIN OUTCOME MEASURES: We computed five measures (patient, primary care, diagnosis, total diagnosis and total treatment intervals). Most studies did not provide any dispersion measure. We then used the sample size of each study to compute a weighted average of the mean intervals. When the median was provided, we assumed normality of the distribution of the means and used the median as a proxy of the mean. RESULTS: A total of 1089 articles were identified, and 22 met the inclusion criteria, reporting on 2710 patients from Europe, USA, India, Australia, Japan, Argentina and Iran. The weighted average of patient interval was 80.3 days. Primary care interval was five times shorter: 15.8 days. The diagnostic interval was appreciably shorter (47.9 days) when compared with the patient interval during symptomatic period. CONCLUSIONS: Patient interval represents the major component of waiting times since the detection of the first signs/symptoms to the definitive diagnosis of oral cancer. Thus, strategies focused on high-risk patients should be prioritised. Interventions aimed at optimising the health systems should be implemented by monitoring and facilitating diagnostic and treatment pathways of patients with oral cancer.

RESUMO

BACKGROUND: Despite continuous advances in diagnosis and therapy, oral cancers are mostly diagnosed at advanced stages with minor survival improvements in the last two decades. Both phenomena have been attributed to delays in the diagnosis. This study aims at quantifying the time elapsed until definitive diagnosis in these patients and the patient interval's contribution. MATERIAL AND METHODS: A hospital-based, ambispective, observational study was undertaken on incident cases with a pathological diagnosis of oral squamous cell carcinoma recruited during 2015 at the Oral and Maxillofacial Surgery services of CHUAC (A Coruña) and POVISA (Vigo) hospitals. RESULTS: 74 consecutive oral cancer patients (59.5% males; median age: 65.0 years (IQ:57-74)) were studied. Most cases (52.7%; n=39) were at advanced stages (TNM III-IV) at diagnosis. The period since first sign/symptom until the patient seeks health care was the longest interval in the pathway to diagnosis and treatment (median: 31.5 days; IQR= 7.0 - 61.0) and represents >60% of the interval since symptom onset until referral to specialised care (pre-referral interval). The average interval assigned to the patient resulted to be relatively larger than the time elapsed since the patient is seen at primary care until a definitive diagnosis is reached (diagnostic interval). Median of the referral interval for primary care professionals: 6.5 days (IQR= 0.0 - 49.2) and accounts for 35% (19% - 51%) of the diagnostic interval. CONCLUSIONS: The patient interval is the main component of the pathway to treatment since the detection of a bodily change until the definitive diagnosis. Therefore, strategies focused on risk groups to shorten this interval should be implemented in order to ease an early diagnosis of symptomatic oral cancer.

RESUMO

Objetivo: Determinar si una política local, establecida en la Maternidad del Hospital Padre Hurtado (HPH), para bajar la incidencia de Encefalopatía Hipóxico Isquémica es efectiva, sin incrementar en forma relevante la tasa de cesáreas. Diseño: Estudio de cohorte. Escenario: Unidad de Gestión Clínica de la Mujer y el Recién Nacido del Hospital Padre Hurtado. Población: Neonatos mayores de 33 semanas de edad gestacional, nacidos en el Hospital Padre Hurtado durante los años 1999 y 2015. Método: Se revisaron los resultados de una política de intervención para prevención de asfixia neonatal establecida en la Maternidad del Hospital Padre Hurtado durante un periodo de 14 años. Resultados: Al analizar los datos de un total de 102.612 nacidos vivos, se constató una disminución en la incidencia de EHI en sus 3 grados de una tasa de 4.75/1.000 nacidos vivos previo a la intervención (grupo control) a una tasa de 1.46 por 1.000 nacidos vivos post intervenciones, con alta significancia estadística (p=0,008), llegando en los últimos 6 años a tasa promedio de 0.87/1.000 nacidos vivos. La tasa de EHI moderada y severa bajó de 1.15 por mil nacidos vivos a 0.62, también con alta significancia estadística (p=0.02). La tasa de cesáreas oscilo entre 26-29 % en estos años. Conclusión: La introducción de intervenciones protocolizadas y sistematizadas por medio de la implementación de guías de manejo del trabajo de parto, la capacitación del equipo de profesionales y la auditoría continua de los casos de EHI en el Servicio de Maternidad del Hospital Padre Hurtado se asoció a una disminución significativa de EHI, manteniendo la tasa de cesáreas bajo 30%.


Objectives: Determine whether a local policy to reduce the incidence of neonatal hypoxic-ischemic encephalopathy (HIE), established at the Maternity Unit of Hospital Padre Hurtado (HPH), is effective without significantly increasing the cesarean rate. Design: Cohort study. Setting: Maternity unit of Hospital Padre Hurtado. Population: Newborns older than 33 weeks born at Hospital Padre Hurtado between 1999 and 2015. Methods: The results of a training policy to prevent HIE and perinatal asphyxia established at the Maternity unit of Hospital Padre Hurtado were reviewed during a period of 14 years. Results: From a total of 102.612 newborns analyzed, results showed a decrease in all grades of HIE incidence, from a rate of 4.75 / 1,000 live births prior to intervention (control group) to a rate of 1.46 per 1,000 live births after interventions, with high statistically significance (p=0.008), it reached an average rate of 0.87/1000 for the last 6 years. The moderate and severe HIE rate decreased from 1.15/1000 to 0.62/1000, also with high statistically significance (p=0.02). During the same period of time, the cesarean rate varied between 26-29%. Conclusion: The introduction of protocolized and systematized interventions trough the implantation of Management guides, obstetrics emergency trainings to the professional team and continues audit of the HIE cases at the Maternity unit Hospital Padre Hurtado was associated to a significant decrease of HIE, maintaining the rate of cesareans below 30%.

RESUMO

The aim of this study was to identify key points and time intervals in the patient pathway to the diagnosis of oral cancer, from the detection of a bodily change to the start of treatment. A systematic search of three databases was performed by two researchers independently. Articles reporting original data on patients with symptomatic primary oral or oropharyngeal squamous cell carcinoma that was pathologically confirmed were included. These articles had to include an outcome variable of 'diagnostic delay', 'time interval', or 'waiting time to diagnosis', or report time intervals from first symptom to treatment. Furthermore, the outcome variable had to have a clearly defined start point and end point, with the time measurement presented as a continuous or categorical variable. A total of 1175 reports were identified; 28 articles on oral cancer studies and 13 on oral and oropharyngeal cancer studies were finally included. These papers showed poor quality in terms of questionnaire validation, acknowledgement of biases influencing time-point measurements, and strategies for verification of patient self-reported data. They also showed great heterogeneity. The review findings allowed the definition of key points and time intervals within the Aarhus framework that may better suit the features of the diagnostic process of this neoplasm, particularly when assessing the impact of waiting time to diagnosis.

RESUMO

BACKGROUND: Transplant glomerulopathy (TG) may occur early after transplantation, and electron microscopy may contribute to diagnose it. METHODS: We analyzed kidney transplant biopsies from September 2009 to September 2012 to identify the presence of histologic changes associated with TG. RESULTS: Forty-eight biopsies from 65 patients, met the study criteria and were evaluated. The average evolution time of transplantation was 13.6 months. Sixty percent of patients received deceased-donor renal transplants, and biopsies were performed per protocol in most cases. Electron microscopy diagnosed the presence of changes associated with TG in 23% of patients. Light microscopy was not useful in the diagnosis of such graft pathology. The average transplantation time was significantly higher in patients with TG compared to patients without TG (20.6 mo vs 11.5 mo; P = .03). Light microscopy diagnosed mild interstitial fibrosis/tubular atrophy in 27 patients, of which 6 had early changes of TG according to the analysis by electron microscopy. CONCLUSIONS: Electron microscopy improves accurate diagnosis of TG, in patients both with and without graft dysfunction. It also allows diagnosis of early TG and thereby identification of patients who may have lower graft survival.

RESUMO

Introducción: El contacto piel a piel postparto es importante pues favorece la lactancia, la adaptación del recién nacido y la relación entre la madre y el hijo. La observación clínica de este período de transición es fundamental. Caso clínico: Se presentan dos casos de eventos adversos serios producidos en el período piel a piel postparto, sin que se identifiquen patologías que expliquen el evento. Uno de los casos presenta secuelas neurológicas. En ambos casos estaban con observación de los padres. Discusión: La literatura ha reportado estos casos durante período neonatal, generalmente precoces, en madres primíparas, frecuentemente en posición prono. Proveer contacto precoz debe considerar un ambiente terapéutico y adecuada observación clínica, sin delegar esta responsabilidad en los padres.


Introduction: The postpartum skin to skin contact (SSC) facilitates breastfeeding, newborn adaptation and the relationship between mother and child. Clinical observation of this transition period is essential. Case study: Two cases of serious adverse events produced in the postpartum SSC period are presented without identified pathology to explain the event. One case presented neurologic sequelae. Both cases were under the parents' watch. Discussion: The literature has reported these cases during neonatal period, usually in early stage, in primiparous mothers, and often in prone position. Providing early contact between the two of them should consider a therapeutic environment and adequate clinical observation, without delegating this responsibility to the parents.

RESUMO

BACKGROUND: The purpose of two similarly designed multicenter, prospective, parallel-group, open-label studies was to evaluate early cyclosporine (CsA) elimination versus minimization from an everolimus-CsA-steroid regimen in de novo renal transplant patients. METHODS: Within 24 hours after transplantation, 170 renal transplant patients received everolimus (trough levels 3-8 ng/mL), CsA, and steroids. Those eligible (n = 114) were randomized (1:1) at 3 months to have CsA elimination by month 4 to 6 (±1 week) with everolimus trough levels maintained at 6 to 12 ng/mL or CsA minimization, until 12 months. The randomized population excluded those who discontinued the study prior to randomization due to adverse events, acute rejection episodes of Banff grade IIb/III, or worsening renal function during the month prior to randomization. RESULTS: At 12 months, the estimated glomerular filtration rate (Nankivell) with CsA elimination was noninferior versus CsA minimization (P < .0001, α-level 0.05; 90% confidence interval 0.6-8.5) by 7 mL/min/1.73 m(2) (noninferiority margin). Composite efficacy failure was comparable with CsA elimination and CsA minimization (18.9% and 17.5%, respectively, P = 1.000) and no graft loss or death was reported after randomization. Cytomegalovirus infections were rare under everolimus treatment, and no pneumonitis episode was reported. CONCLUSION: In our selected randomized study population, immediate initiation of everolimus allowed CsA elimination. Renal function was stable on everolimus-based, CsA-free maintenance regimen without compromising efficacy.

RESUMO

INTRODUCTION: End-stage renal disease (ESRD) is a prevalent, important cause of death. Transplantation increases survival and improves the quality of life of patients with ESRD while long-term dialysis is related to poor outcomes even among patients who undergo subsequent transplantations. OBJECTIVES: To compare the advantages of preemptive procedures with kidney transplants among patients on renal replacement therapy. METHODS: This retrospective study was performed in two Córdoba city transplantation centers. Patients were divided into three groups: preemptive kidney transplant (PKT), patients on hemodialysis who received living donor kidney transplants (LDT), and subjects who received grafts from deceased donors (DDT). Serum creatinine, delayed graft function (DGF), subclinical rejection, and interstitial fibrosis/tubular atrophy (IF/TA) were evaluated at 6 months. RESULTS: Eighty patients were included: PKT (n = 28), LDT (n = 27), DDT (n = 25) mean age 29, 30, and 35 years, respectively. Women predominated among PKT and men in the other groups. In all groups, cyclosporine was the calcineurin inhibitor mostly used. Creatinine at 6 months was lower in the living donor groups (1.26 mg/dL PKT and 1.32 mg/dL LDT; P = NS) in relation to the deceased donor group (1.96 mg/dL; P < .05). DDT had the highest rate of DGF: 44% DDT versus 11.5% LDT vs 0% PKT (P < .05). Subclinical rejection was significantly lower among preemptive transplantations: PKT 7.6% versus LDT 18.5% versus DDT 24% (P < .05). IF/TA was higher in transplants from deceased donors: PKT 11.1%; LDT 11.5%; DDT 32%. CONCLUSIONS: Preemptive kidney transplantation offered the advantages of a lower creatinine, no DGF, as well as a reduced incidence of subclinical rejection and chronic allograft nephropathy at 6 months posttransplantation.

RESUMO

Management of posttransplantation malignancies should include control of the neoplasia and preservation of renal function. Conversion to everolimus (EVL) would potentially have both effects. Twenty-one patients were converted to EVL due to posttransplantation neoplasms. We have presented herein descriptive data and postconversion (PC) outcomes among subjects of mean age 53.6 +/- 10.1 years (range, 36-69), 57.1% were males, undergoing conversion at 108.2 +/- 74.7 (range, 5-316) months after transplantation. All patients received standard immunosuppressive therapy and 9.5% had been induced with thymoglobulin. Malignant neoplasms were as follows: skin (n = 7), gynecological (n = 3), gastrointestinal (n = 3), PTLD (n = 2), renal (n = 2), CNS (n = 1), seminoma (n = 1), Kaposi's sarcoma (n = 1), and prostate cancer (n = 1). PC to EVL, calcineurin inhibitors (CNIs) were discontinued in 18 of 19 patients, mycophenolate in 9/12, and azathioprine in 5/7; all patients continued to receive steroids. In 16 patients (79%) tumors were removed. Chemotherapy was performed in 2 patients with PTLD and radiotherapy was performed in 1 patient with prostate cancer. Mean follow-up was 505 days (range, 59-1151); baseline glomerular filtration rate (GFR) was 53.5 +/- 21.6 mL/min versus 48.5 +/- 25.7 mL/min (P = not significant [NS]) at the last control. One patient experienced graft loss at day 744 after conversion due to chronic rejection. Adverse events were observed in 57% of patients and 28% displayed infections; no patient discontinued EVL. There were 2 deaths: 1 due to an infection and the other due to postsurgical complication. No deaths due to cancer progression were observed. The results observed in this series suggested that conversion to EVL for a posttransplantation neoplasm is a valid therapeutic alternative to preserve graft function and control disease progression.

RESUMO

ANTECEDENTES: Citomegalovirus (CMV) es la infección congénita más frecuente, demostrado en el 1% de recién nacidos en países desarrollados. Es la primera causa de sordera y alteraciones del desarrollo neuro-lógico infantil. Recientes estudios han demostrado que la seropositividad no evita una reinfección materna ni la enfermedad congénita, por lo que la caracterización de la seroprevalencia permite saber si la infección congénita proviene mayoritariamente de primoinfección o de reinfección. OBJETIVOS: Conocer la seroprevalencia al parto en 583 mujeres beneficiarías del Hospital Padre Hurtado durante mayo y junio del 2006. MÉTODOS: Estudio prospectivo, observacional, en que se estudio la presencia de IgG anti CMV en sangre materna al parto. RESULTADOS: Se obtuvo una seroprevalencia de 95%, sin casos de infección sintomática al nacer. CONCLUSIÓN: La seroprevalencia es elevada, lo que sugiere que la reinfección sería la forma principal de infección congénita. Un estudio en recién nacidos con cultivos virales o PCR permitiría conocer la tasa de infección congénita real, y no un estudio basado en seroconversión pues omitiría todos los casos que reinfección, que serían mayoritarios.


BACKGROUND: Cytomegalovirus is the most frequent congenital infection, affecting 1% of the population in developed countries, and the leading cause of deafness and brain development abnormalities in children. Recent studies have demonstrated that seropositivity do not avoid reinfection and congenital disease. OBJECTIVE: To study the seroprevalence in 583 pregnant women at delivery at Padre Hurtado Hospital, during 2006. METHODS: Prospective, observational study, in which maternal blood at delivery was studied for the presence of anti CMV IgG. RESULTS: There was 95% seroprevalence, without any case of symptomatic infection. CONCLUSION: The high prevalence supports that most of the cases of congenital disease would occur in seropositive women, supporting that reinfection is the main way of neonatal compromise. This supports that a study with direct detection in liveborns would be suitable to reveal the impact of cytomegalovirus in our population and not that of seroconversión.

RESUMO

The introduction of mycophenolate as an adjuvant in immunosuppressive regimes has improved clinical outcomes of transplant patients due to a reduced incidence of acute rejection episodes. Nevertheless, the need for dose adjustments or therapy discontinuations (up to 45% in some series), have downgraded the efficacy of mycophenolate mofetil (MMF). From October 2003 to April 2005, 36 kidney transplantations were performed at our site. The immunosuppressive protocol included induction with basiliximab, administered on days 0 and 4 posttransplantation, cyclosporine microemulsion (CsA-ME) monitored by concentrations at 2 hours (C2), enteric-coated sodium mycophenolate (EC-MPS; 720 +/- 180 mg bid), and steroids. Mean follow-up time was 7.3 +/- 4.4 months. Fourteen patients (38.9%) experienced delayed graft function (DGF). Seven (19%) episodes of acute rejection included 5 graded as I-A, 1 as grade I-B, and 1 as grade II-A. There were discontinuations of EC-MPS. Regarding gastrointestinal (GI) adverse events, there were 2 episodes of noninfectious diarrhea, 1 gastritis, and 1 upper GI hemorrhage. There were 11 infections: 4 in the urinary tract; 3 in the lung; 3 in the GI tract; and 1 CMV infection. There were no discontinuations of EC-MPS reported [corrected] Two (6%) graft losses were reported to be due to sepsis. In this group of patients who experienced a high incidence of DGF, the combination of basiliximab, CsA-ME (monitored by C2), and EC-MPS resulted in low Banff grade acute rejection episodes which were all responsive to steroids. The incidence of GI adverse events was only 11%.

RESUMO

Patients with delayed graft function (DGF) are at risk of increased incidence for acute rejection episodes (ARE). Mycophenolate mofetil or induction therapy has produced a reduction in ARE incidence. An open, prospective, 3-month trial was performed in a group of Argentinian renal transplant recipients. We recruited 46 patients, 71.7% men, aged 41.7 +/- 13.8 years; including 36 (78.3%) recipients of cadaveric donors (CD) who were aged 43.4 +/- 15.5 years with a cold ischemia time of 19.4 hours +/- 5.4 minutes, and 10 (27.7%) recipients of living donors (LD) aged 37.8 +/- 12.9 years. HLA mismatches >or= 3 were observed in 58.4% of CD and in 7% of LD. All patients received two doses of basiliximab (20 mg each, days 0 and 4), cyclosporine microemulsion (CsA-ME) monitored by the second-hour concentrations (C2), enteric-coated mycophenolate sodium (EC-MPS; 720 mg twice a day, and steroids. A 58% incidence of DGF was observed. At the end of the third month the incidence of biopsy-proven ARE was 15%, with a median serum creatinine of was 1.54 +/- 0.42 mg/dL, including three grafts lost. Two patients died. No patient required EC-MPS dose discontinuation but 20% of patients required dose adjustments. The absence of discontinuations and the low incidence of dose adjustments of EC-MPS in this high-risk de novo population provided support of a suitable tolerability profile for this EC-MPS, and the possibility to impact efficacy results.
