RESUMEN
@#Background and Objective. Choledochal cysts (CC) are rare congenital, cystic dilations of the biliary tree occurring predominantly in Asian populations and in females. Patients are usually children presenting with any of the following: abdominal pain, palpable abdominal mass, and jaundice. Its congenital nature hints at a potential genetic cause. A possible causal gene is TP53, a tumor suppressor with a germline variant called rs201753350 (c.91G>A) that changed from a G allele to an A allele, decreasing the cell proliferation suppressing activity of its functional protein. Currently, there is no information on the TP53 rs201753350 germline variant available for the Filipino population. This study determined the prevalence of rs201753350 and the association between the functional G allele, the rs201753350 germline variant A allele, and the occurrence of CCs in Filipino pediatric patients in a tertiary government hospital. Methods. Genomic DNA was extracted from blood samples of pediatric patients clinically diagnosed with CC. Controls were DNA samples collected from a previous study. The samples underwent PCR, electrophoresis, and sequencing. Results. A total of 109 participants (22 cases and 87 controls) were included in the study. The A allele (22.94%) occurs at a lower frequency than the G allele (77.06%) among both cases and controls. More individuals have a homozygous G/G genotype (54.13%) than a heterozygous A/G genotype (45.87%) while the homozygous A/A genotype was not observed. The estimated risk of choledochal cyst occurrence is significantly lower in individuals with the A allele (PR: 0.08, 95% CI: 0.01 – 0.55) and the A/G genotype (PR: 0.06, 95% CI: 0.01 – 0.40). Conclusion. There is no significant evidence to suggest an association between the TP53 rs201753350 germline variant and the occurrence of choledochal cysts in Filipinos. It is recommended that other mutations within and beyond the TP53 gene be investigated for possible associations with choledochal cyst occurrence.

Objetivo: Atualizar a estatística do serviço, reconhecendo a prevalência de amnior- rexe prematura no pré-termo e seus principais desfechos materno-fetais. Méto- dos: Estudo transversal realizado pela análise de prontuários médicos de pacien- tes internadas devido a amniorrexe prematura no pré-termo e de seus respectivos conceptos no Hospital Universitário da Faculdade de Medicina de Jundiaí durante o período de janeiro de 2020 a dezembro de 2021. Resultados: Participaram da pesquisa 161 pacientes e 166 conceptos, resultando em uma prevalência de 2,12% no período estudado, com intervalo de confiança de 95% (1,80-2,47). Entre os des- fechos maternos, 2,5% das gestantes compunham critérios para near miss mater- no; enquanto entre os desfechos fetais, o resultado foi de 54,8% dos conceptos apresentando complicações, sendo as mais prevalentes a síndrome do desconfor- to respiratório (36,3%), icterícia (39,5%), baixo peso (27,5%) e hipoglicemia (24,2%). Além disso, 40,4% necessitaram de internação na unidade de terapia intensiva, 22,9% foram classificados como near miss neonatal e 4,4% foram a óbito. Conclu- são: Os resultados seguiram os padrões nacionais e internacionais esperados para prevalência de amniorrexe prematura no pré-termo e seus desfechos materno-fe- tais, com alta porcentagem de internações e complicações neonatais e baixa taxa de complicações maternas.
Objective: To update service statistics, recognizing the preva- lence of the pathology and its main outcomes. Methods: Cros- s-sectional study carried out through the analysis of medical records of patients hospitalized due to preterm premature rup- ture of membranes and their respective fetuses at the Univer- sity Hospital of Jundiaí's Medical School during the period from January 2020 to December 2021. Results: A total of 161 patients and 166 fetuses participated in the research, resulting in a pre- valence of 2.12% in the period studied with 95% confidence in- terval (1.80-2.47). About the outcomes, 2.5% of the pregnant wo- men composed the criteria for maternal near miss; as for the fetus, complications evolved in 54.8% of the fetuses, the most prevalent being respiratory distress syndrome (36.3%), jaundice (39.5%), low birth weight (27.5%) and hypoglycemia (24.2%). In addition, 40.4% required admission to the intensive care unit, 22.9% were neonatal near miss and 4.4% died. Conclusion: The results followed the expected national and international standards for the prevalence of preterm premature rupture of membranes and its maternal and fetal outcomes, with a high percentage of hospitalizations and neonatal complications, and a low rate of maternal complications.

The growth environment of medicinal plants plays an important role in the formation of their medicinal quality. However, there is a lack of combined analysis studying the close relationship between the growth environment, chemical components, and related biological activities of medicinal plants. Therefore, this study investigated the effect of different soil moisture treatments on the efficacy to eliminate dampness and relieve jaundice and the flavonoid content of Sedum sarmentosum, and explored their correlation. The flavonoid content in the decoction of S. sarmentosum growing under field conditions with soil moisture levels of 35%-40%(T1), 55%-60%(T2), 75%-80%(T3), and 95%-100%(T4) was compared. The effects of these treatments on liver function parameters, liver inflammation, and oxidative damage in mice with dampness-heat jaundice were evaluated, and the correlation between pharmacological indicators and flavonoid content was analyzed. The results showed that the total flavonoid and total phenolic acid content in the decoction of S. sarmentosum were highest in the T1 treatment, followed by the T3 treatment. The content of quercetin, kaempferol, and isorhamnetin was highest in the T2, T1, and T3 treatments, respectively. Among the different moisture treatments, the T3 group of S. sarmentosum effectively reduced the levels of serum ALT, AKP, TBIL, DBIL, TBA, as well as hepatic TNF-α and IL-6 in mice with jaundice, followed by T2 treatment, especially in reducing AST level. The T4 treatment had the poorest effect. Correlation analysis showed a significant negative correlation between AST, ALT, AKP levels in mice and the total content of quercetin and the three flavonoids. MDA showed a significant negative correlation with the total flavonoid content and kaempferol. TNF-α exhibited a significant negative correlation with the content of isorhamnetin. In conclusion, S. sarmentosum growing under field conditions with a soil moisture level of 75%-80% exhibited the best efficacy to eliminate dampness and relieve jaundice. This study provides insights for optimizing the cultivation mode of medicinal plants guided by pharmacological experiments.

Introducción. Aproximadamente el 5 % de los divertículos duodenales pueden causar síntomas y el 1 % presentar complicaciones, siendo la colangitis la más frecuente. El síndrome de Lemmel corresponde a un tipo de ictericia obstructiva intermitente, asociado a la presencia de divertículos periampulares y disfunción del esfínter de Oddi, sin presencia de coledocolitiasis. Método. Se realizó una revisión sistemática de la literatura en Pubmed, Google Académico y ProQuest, con los términos: síndrome de Lemmel, divertículo duodenal sintomático e ictericia obstructiva intermitente. Resultados. Se encontraron 38 casos, siendo España el país con mayor número, seguido de México, Japón y Colombia. No hay diferencias de distribución con respecto al género. El tratamiento más frecuentemente empleado fue la colangio pancreatografia retrógrada endoscópica. Conclusión. El síndrome de Lemmel es poco frecuente, sin un cuadro clínico especifico, con un incremento en los casos informados en los últimos años, posiblemente debido a la mejor disponibilidad de métodos diagnósticos. Es más frecuente en pacientes en la octava década de la vida y su tratamiento generalmente es endoscópico
Introduction. Approximately 5% of duodenal diverticula can cause symptoms and 1% have complications, cholangitis being the most common. Lemmel syndrome corresponds to a type of intermittent obstructive jaundice, associated with the presence of peri-ampullary diverticula and sphincter of Oddi dysfunction, without choledocholithiasis. Method. A systematic review of the literature was carried out in Pubmed, Google Scholar, ProQuest, with the terms: Lemmel syndrome, symptomatic duodenal diverticulum, and intermittent obstructive jaundice.Results. 38 cases were found, Spain being the country with the highest number, followed by Mexico, Japan and Colombia. There are no differences in distribution with respect to gender. The most frequently used treatment was endoscopic retrograde cholangiopancreatography.Conclusion. Lemmel syndrome is a rare disease, without a specific clinical presentation, with an increase in reported cases in recent years possibly due to the better availability of diagnostic methods. It is more frequent in patients in the eighth decade of life and its treatment is generally endoscopic

Abstract Introduction: We describe the case of a patient with appendiceal metastasis as the first manifestation of a cholangiocarcinoma. Main symptoms: Abdominal pain, jaundice, hyporexia, and choluria. Methods and results: We documented an appendiceal plastron histologically compatible with metastatic appendiceal adenocarcinoma, common hepatic duct stricture, and a suspected cholangiocarcinoma, later corroborated by endoscopic retrograde cholangiopancreatography. Conclusions: Metastatic appendiceal tumors are an infrequent and poorly studied manifestation, whereas those secondary to bile duct neoplasia have rarely been reported in the literature.

La historia natural de la enfermedad hepática crónica (EHC) se caracteriza por una fase de cirrosis compensada asintomática seguida de una fase descompensada, que se acompaña de signos clínicos evidentes, de los cuales los más frecuentes son la ascitis, las hemorragias, la encefalopatía y la ictericia. Esta guía actualizada sobre el manejo de pacientes con EHC en la edad pediátrica fue confeccionada con el propósito de mejorar la práctica clínica de estos pacientes complejos y darle herramientas al pediatra de cabecera para un seguimiento adecuado. Para ello, un grupo de expertos subrayó la importancia del inicio temprano del tratamiento etiológico en cualquier grado de enfermedad hepática y ampliaron su labor jerarquizando las complicaciones de la cirrosis: ascitis, hemorragia digestiva, infecciones, malnutrición; aspectos endocrinológicos, neurológicos, oftalmológicos y gastrointestinales; y complicaciones vasculares pulmonares y renales. Se incluyeron, además, aspectos psicosociales, así como el cuidado del adolescente en su transición a la vida adulta.
The natural history of chronic liver disease (CLD) is characterized by a phase of asymptomatic compensated cirrhosis followed by a decompensated phase, accompanied by the development of evident clinical signs, the most frequent being ascites, hemorrhages, encephalopathy and jaundice. This updated guideline on the management of pediatric patients with CLD was developed with the purpose of improving the clinical practice of these complex patients and to provide the pediatrician with tools for an adequate follow-up. To this end, a group of experts, after stressing the importance of early initiation of etiologic treatment in any degree of liver disease, expanded their work to include a hierarchy of complications of cirrhosis: ascites, gastrointestinal bleeding, infections, malnutrition, endocrinological, neurological, ophthalmological, gastrointestinal, pulmonary vascular and renal complications. Psychosocial aspects including the care of the adolescent in their transition to adult life were also included.

Background: Hepatitis B virus infection is one of the leading causes of liver diseases which occurs worldwide particularly in developing countries. It is often caused by prenatal transmission from mother to child or household transmission from a close contact during early childhood. It causes different complications like; jaundice, induces premature labor, and prematurity. Objective: The aim of this study was to estimate the sero-prevalence of hepatitis B virus surface antigen and associated factors among women of reproductive age in Bench Maji Zone, South West Ethiopia. Methods: A community-based cross-sectional study was conducted from December 15th, 2016 to February 15th, 2017. Multistage sampling technique was applied to select study participants. Logistic regression analysis was applied and p-values < 0.05 was used to see the significant association between dependent and independent variables. Results: A total of 330 participants were included in this study yielding 98.8% response rate. The sero-prevalence of HBsAg among women of reproductive age was 28(8.5%). Having multiple sexual partners (AOR = 18.73, 95% CI =3.65, 96.21) history of unprotected sex (AOR = 9.39, 95% CI =1.64, 53.77) were found to be significantly associated with sero-prevalence of HBV. Conclusions: The sero-prevalence of HBV infection among women of reproductive age was highly endemic. Hence, behavioral education and communication programs focusing on reduction of risky sexual behaviors should be designed to reduce HBV infection.

@#Congenital cytomegalovirus (CMV) infection (cCMV) is challenging to differentiate from congenital rubella syndrome (CRS) clinically. Virus detection and serological tests are needed. However, they are often not readily available or are expensive. This is a case of a five-month-old male with bilateral cataracts. He was jaundiced at birth and started having seizure episodes at one month of age. He was also diagnosed with right inguinal hernia and had abnormal bilateral hearing tests. Both eyes were noted to have leukocoria at two months of age. There was dazzle on both eyes and sclerae were anicteric. Examination revealed dense cataracts on both eyes, but their ocular ultrasound results were essentially normal. Due to the bilateral hearing loss and bilateral cataracts, CRS was initially considered despite the absence of heart abnormality since there were reported CRS cases without the complete triad. However, possible coinfection or another disease was considered due to the presence of jaundice, seizures, and hernia, which were never seen in our previous CRS patients nor were reported in the literature. The patient underwent cataract extraction on both eyes without intraocular lens implantation (IOL) as recommended for CRS cataracts to prevent severe inflammation. TORCH (TOxoplasmosis, Rubella, Cytomegalovirus, Herpes simplex) test was negative for rubella but positive for CMV. As such, the patient would have benefitted from early IOL implantation. The patient was then referred to a national medical center for possible treatment. However, since the patient already tested negative for CMV polymerase chain reaction (PCR) there, systemic antiviral therapy was no longer initiated. This case presented the challenge of clinically differentiating cCMV and CRS.

Los niveles de bilirrubina sérica normal en el adulto varían entre 0,3 mg/dL y 1,2 mg/dL, y su valor está determinado por la tasa de captación hepática, conjugación y excreción. La ictericia se hace evidente cuando los niveles de bilirrubina sérica se elevan por encima de 2,5 mg/dL a 3 mg/dL, siendo un indicador de enfermedad subyacente. La bilis es producida por los hepatocitos y fluye desde los canalículos, canales de Hering, conductos biliares intrahepáticos, conductos hepáticos derechos e izquierdos hasta llegar al duodeno. A nivel histopatológico, cualquier entidad que lleve a la acumulación intrahepática de bilis por disfunción hepatocelular u obstrucción biliar genera colestasis, que se observa en la biopsia hepática como la acumulación de tapones de color marrón verdoso de pigmento biliar en los hepatocitos, y secundariamente se observan los canalículos dilatados. Las causas de colestasis intrahepática son diversas e incluyen enfermedades como colangitis biliar primaria, colangitis esclerosante primaria, hepatitis autoinmune, hepatitis virales y toxicidad medicamentosa. Esta revisión tiene como objetivo analizar algunos tipos de hiperbilirrubinemia, resaltando sus características histopatológicas.
Normal serum bilirubin levels in adults range from 0.3 mg/dL to 1.2 mg/dL, and its value is determined by the rate of hepatic uptake, conjugation, and excretion. Jaundice becomes apparent when serum bilirubin levels rise above 2.5 mg/dL to 3.5 mg/dL and is an indicator of underlying disease. Bile is produced by hepatocytes and flows from the canaliculi, Hering's canals, intrahepatic bile ducts, and right and left hepatic ducts to the duodenum. Pathologically, any condition that leadsto intrahepatic accumulation of bile due to hepatocellular dysfunction or biliary obstruction, generates cholestasis, which is observed in liver biopsy as the accumulation of greenish-brown deposits of bile pigment in hepatocytes, with dilated canaliculi. The causes of intrahepatic cholestasis are diverse and include diseases such as primary biliary cholangitis and primary sclerosing cholangitis, autoimmune hepatitis, viral hepatitis, and drug toxicity. This review aims to analyze some types of hyperbilirubinemia, highlighting their histopathological characteristics.

La talidomida fue desarrollada e introducida al mercado por los laboratorios Grünenthal en 1953, siendo usada principalmente como sedante y también para el tratamiento de las náuseas durante el embarazo. Los informes dan cuenta de aproximadamente 10.000 niños que nacieron con focomelia, dando lugar a la denominada "tragedia de la talidomida", que obligó a su retiro del mercado en 1962. Luego de casi 60 años, es nuevamente utilizada en otros campos de la medicina, entre ellos, para el tratamiento de la lepra y del mieloma múltiple, debido a sus propiedades antinflamatorias, inmunomoduladoras y antiangiogénicas, con expresas advertencias sobre su utilización durante el embarazo; no obstante, con su nuevo uso han sido reportados múltiples efectos adversos, entre los que se encuentra la hepatitis aguda o crónica inducida por este fármaco. Se presenta el caso de una paciente de 34 años con lepra, que estaba en tratamiento con talidomida desde hacía 4 años para combatir las lesiones de piel asociadas a esta enfermedad. Presentó malestar general, vómito, pérdida de peso, artralgias, ictericia, edemas de miembros inferiores, ascitis, coluria y acolia. Se sospechó toxicidad por talidomida, por lo que se suspendió su uso, y se trató con ácido ursodesoxicólico y N-acetilcisteína con mejoría sintomática y de laboratorio, desde la primera semana hasta los 41 días de seguimiento. Las entidades clínicas para las cuales se aprobó talidomida en 1998, pueden traer nuevos problemas y desafíos clínicos. Este caso muestra hepatotoxicidad crónica por talidomida, situación que hasta el momento no se había reportado en la literatura.
Thalidomide was developed and introduced to the market by Grünenthal laboratories in 1953, being used mainly as a sedative and also for the treatment of nausea during pregnancy. Reports give account of approximately 10,000 children who were born with phocomelia, giving rise to the so-called "thalidomide tragedy", which forced its withdrawal from the market in 1962. After almost 60 years, it is usedagain in other fields of medicine, including the treatment of leprosy and multiple myeloma, due to its anti-inflammatory, immunomodulatory and anti-angiogenic properties, with clear warnings about its use during pregnancy; however, multiple adverse effects have been reported in patients with leprosy and multiple myeloma, including acute or chronic hepatitis. We present the case of a 34-year-old patient with leprosy, who had been on thalidomide therapy for 4 years to treat skin lesions associated with this disease. She presented general malaise, vomiting, weight loss, arthralgia, jaundice, lower limb edema, ascites, choluria and acholia. Thalidomide toxicity was suspected, so its use was suspended, and treatment with ursodeoxycholic acid and N-acetylcysteine was initiated, with symptomatic and laboratory improvement from the first week up until 41 days of follow-up. The new range of medical conditions for which thalidomide was approved for in 1998 may bring clinical challenges. This case shows chronic hepatotoxicity due to thalidomide, a situation that had not been reported previously in the literature.

Los antibióticos y analgésicos han sido descritos frecuentemente como las principales causas de toxicidad hepática. Los esteroides anabólicos se han relacionado también con alteraciones en sistemas como el cardiovascular o el hepático; en este último causan colestasis, carcinoma hepatocelular, hiperplasia regenerativa nodular y sangrado de varices, secundario a hipertensión portal. Es importante entonces considerar los esteroides anabólicos como factores de riesgo para hepatotoxicidad. Se presenta el primer caso en Colombia y uno de los pocos en Latinoamérica, de colestasis asociada únicamente al uso de estanozolol. Se trata de un paciente de 21 años, en tratamiento con el medicamento para incrementar la masa muscular, que presentó compromiso hepático de tipo colestásico. Se descartaron otras posibles causas de ictericia, mediante la escala CIOMS/RUCAM se llegó a establecer causalidad entre el consumo de estanozolol y la colestasis. El objetivo de este reporte es hacer una descripción no reportada en la literatura colombiana y poco común en la literatura mundial.
Antibiotics and pain relievers have been frequently described as the main causes of liver toxicity. Anabolic steroids have also been linked to alterations in systems such as cardio-vascular or liver. In the latter, they seem to cause cholestasis, hepatocellular carcinoma, nodular regenerative hyperplasia and variceal bleeding secondary to portal hypertension. It is important to consider them as factors associated with hepatotoxicity. The first case in Colombia and one of the few in Latin America of cholestasis associated only to the use of Stanozolol is presented in a 21-year-old patient under treatment with the drug to increase muscle mass. The patient presented with cholestatic liver involvement. Other possible causes of jaundice were ruled out. From the CIOMS / RUCAM scale, causality was established between the consumption of Stanozolol and cholestasis. The objective of this case is to report a case not found in Colombian literature and little reported in world literature.

Hematúria é uma grave manifestação clínica de doença do sistema urinário, ocorrendo sob as formas micro ou macroscópica. Neste artigo relatam-se dois casos de hematúria macroscópica associada à infecção por Leptospira interrogans sorogrupo Canicola. O exame clínico inicial revelou hematúria macroscópica, taquicardia, taquipneia, febre, elevação do tempo de perfusão capilar, hipomotilidade intestinal, além de icterícia da mucosa oral. Leucocitose, proteinúria, glicosúria, piúria e azotemia foram achados comuns aos dois casos. Teste de Soroaglutinação Microscópica foi realizado para titulação de anticorpos contra Leptospira interrogans. Tratamento incluiu medidas terapêuticas de suporte (fluidoterapia), controle da hematúria e antibioticoterapia. Sete dias após manifestação dos sinais clínicos iniciais, ambos animais receberam alta hospitalar após remissão dos sinais clínicos.
Haematuria is a serious clinical manifestation of urinary system disease, occurring in micro or macroscopic forms. In this article two cases of macroscopic haematuria associated with Leptospira interrogans serogroup Canicolainfection are related. The initial clinical examination revealed macroscopic haematuria, tachycardia, tachypnea, fever, increased capillary perfusion time, intestinal hypomotility, in addition to jaundice of the oral mucosa. Leukocytosis, proteinuria, glycosuria, pyuria and azotemia were common findings in both cases. Microscopic serum agglutination test was performed for titration of antibodies against Leptospira interrogans. Treatment included supportive therapeutic measures (fluid therapy), hematuria control and antibiotic therapy. Seven days after the manifestation of the initial clinical signs, both animals were discharged from the hospital without complications.

Resumen La hemobilia es una causa poco frecuente de hemorragia del tracto gastrointestinal superior. La principal etiología es de origen iatrogénico y la posibilidad de hemobilia debe considerarse en cualquier paciente con hemorragia gastrointestinal y un historial reciente de procedimientos hepatobiliares. Otras causas menos frecuentes incluyen el trauma de abdomen, la enfermedad oncológica de la vía biliar o las enfermedades inflamatorias del páncreas o la vía biliar. La presentación clínica varía según la gravedad del sangrado; generalmente se presenta con dolor abdominal, ictericia y melenas, aunque puede cursar al ingreso con rectorragia e hipotensión. Un alto porcentaje de estas presenta resolución espontánea, sin requerir procedimientos adicionales. La angiografía es el estándar de oro para el diagnóstico de la hemobilia, pero los avances en la angiotomografía permiten que esta sea una opción menos invasiva y con mayor disponibilidad. La angioembolización es el tratamiento principal para estos pacientes, pero existen otras alternativas como la colocación de stent vascular o de stent en el conducto biliar.
Abstract Hemobilia is a rare cause of upper gastrointestinal (GI) tract bleeding. Its main etiology is iatrogenic, and the possibility of hemobilia should be considered in any patient with GI bleeding and a recent history of hepatobiliary surgery. Other less frequent causes include abdominal trauma, oncologic disease of the biliary tract, or inflammatory diseases of the pancreas or bile duct. Its clinical presentation varies depending on the severity of the bleeding. It usually presents with abdominal pain, jaundice, and tarry stools, although patients may also present with rectorrhagia and hypotension on admission. A high percentage of these symptoms have a spontaneous resolution, without requiring additional procedures. Angiography is the gold standard for the diagnosis of hemobilia, but advances in computed tomography angiography make it a less invasive and more widely available option. Endovascular embolization is the main treatment for these patients, but there are other alternatives such as vascular or bile duct stent placement.

Resumen La atresia biliar asociada con inmunoglobulina M (IgM) positiva para citomegalovirus (CMV) es una entidad infrecuente que se caracteriza por la obliteración inflamatoria progresiva de los conductos intra- o extrahepáticos producida por una reacción autoinmune perinatal contra el CMV. El diagnóstico se realiza con IgM positiva para CMV y biopsia hepática con evidencia de atresia de las vías biliares. El conocimiento y la identificación temprana de esta patología conduce a un manejo quirúrgico temprano, mejorando considerablemente el pronóstico de estos pacientes. Se presenta un caso clínico de una paciente de 82 días de edad con un cuadro de acolia, coluria e ictericia de inicio tardío, asociado con hiperbilirrubinemia a expensas de la directa, elevación de perfil hepático e IgM positiva para CMV. La colangiorresonancia intraoperatoria confirmó el cuadro de atresia de las vías biliares. Se realizó una derivación biliodigestiva tipo Kasai y la toma de biopsia hepática que confirmó el cuadro clínico.
Abstract Biliary atresia associated with positive cytomegalovirus IgM results is a rare condition characterized by progressive inflammatory obliteration of the intra- or extrahepatic ducts. It is caused by a perinatal autoimmune reaction against cytomegalovirus (CMV). Diagnosis is made based on positive IgM for CMV and liver biopsy with evidence of bile duct atresia. Knowledge and timely identification of this disease leads to early surgical management, considerably improving the prognosis of these patients. This is the clinical case of an 82-day-old female patient with late-onset acholia, choluria, and jaundice, associated with conjugated hyperbilirubinemia, elevated liver function tests and positive CMV IgM results. Intraoperative cholangioresonance confirmed bile duct atresia. The Kasai procedure was performed, and a liver biopsy was taken, confirming the diagnosis.

The uniformity of blue LED array in jaundice treatment box is improved. The mathematical model of illumination uniformity algorithm for inner and outer LED arrays layout is established. Taking the actual size of blue light board in jaundice treatment box as an example, the optimal illumination uniformity with best LED arrays layout are obtained through programming iteration and simulation verification. The uniformity of blue light LED improved 42.9 % comparing with tradition LED arrays.

La colangitis esclerosante primaria (CEP) se define por la inflamación, fibrosis y estenosis de los conductos biliares intra o extrahepáticos que no pueden ser explicadas por otras causas. La prevalencia de CEP está estimada entre 0 a 16,2 por 100.000 habitantes, mientras que la incidencia está entre 0 y 1,3 casos por cada 100.000 personas por año. Las causas siguen siendo difíciles de dilucidar y en muchos casos se establece como de origen idiopático. Sin embargo, se han propuesto factores genéticos, ambientales e isquémicos asociados, además de un componente autoinmune. Existe además una fuerte asociación entre la enfermedad inflamatoria intestinal y la CEP. Los síntomas suelen ser inespecíficos, 50% de los pacientes son asintomáticos, presentando únicamente alteración en el perfil hepático de patrón colestásico, con predominio de elevación de la fosfatasa alcalina. La ictericia es un signo de mal pronóstico que con frecuencia se asocia a colangiocarcinoma. La confirmación diagnóstica se hace por colangiopancreatografía retrógrada endoscópica (CPRE) e imágenes por resonancia magnética. Aún no existe un tratamiento establecido, y en la mayoría de los casos coexiste con otras patologías. El tratamiento es multimodal con fármacos, terapia endoscópica y trasplante hepático.
Primary sclerosing cholangitis (PSC) is defined by inflammation, fibrosis, and stenosis of the intra or extrahepatic bile ducts that cannot be explained by other causes. The prevalence of PSC is estimated between 0 to 16.2 per 100,000 inhabitants, while the incidence is between 0 and 1.3 cases per 100,000 persons-year. The causes remain elusive and, in many cases, it is established as idiopathic in origin. However, genetic, environmental and ischemic factors have been proposed in addition to an autoimmune component. There is also a strong association between inflammatory bowel disease and PSC. Symptoms are usually nonspecific, 50% of the patients are asymptomatic, presenting only an alteration in the liver profile with a cholestatic pattern, and predominance of elevated alkaline phosphatase. Jaundice is a poor prognostic sign and is frequently associated with cholangiocarcinoma. Diagnostic confirmation is made by endoscopic retrograde cholangiopancreatography and magnetic resonance imaging. There is still no established treatment, and in most cases, the disease coexists with other pathologies. Treatment is multimodal with drugs, endoscopic therapy and liver transplantation.

La manifestación paraneoplásica conocida como síndrome de Stauffer tiene una presentación atípica, caracterizada por ictericia y colestasis intrahepática. Presentamos el caso de un paciente de 53 años de edad, con antecedente de una masa renal derecha en plan de resección quirúrgica programada, con cuadro de evolución de dolor abdominal en hipocondrio derecho e ictericia. A su ingreso se documentó hepatoesplenomegalia, elevación de bilirrubinas a expensas de la directa, y de fosfatasa alcalina junto con elevación de transaminasas. Se descartaron causas obstructivas a nivel de vía biliar intra y extrahepática. No se documentaron metástasis o lesiones focales a nivel de parénquima, ni lesiones de etiología vascular que explicaran el cuadro. También se descartó hepatitis B, C e infección por VIH, por lo cual se consideró un probable síndrome de Stauffer. Fue llevado a nefrectomía intrahospitalaria, con posterior diagnóstico patológico compatible con carcinoma de células claras. Luego del procedimiento se normalizó la bioquímica hepática y se corrigió la ictericia. Es importante reconocer que la afectación hepática en el contexto de neoplasias, no es solo atribuida a metástasis a distancia, sino también a la existencia de síndromes paraneoplásicos como condicionantes.
The paraneoplastic manifestation known as Stauffer syndrome has an atypical presentation, characterized by jaundice and intrahepatic cholestasis. We present the case of a 53-year-old patient, with a history of a right renal mass with a planned surgical resection, who developed abdominal pain in the right upper quadrant and jaundice. Upon admission, hepatosplenomegaly, elevated bilirubin, at the expense of direct bilirubin, alkaline phosphatase and elevated transaminases were documented. Intra- and extrahepatic bile ducts obstruction were ruled out. There were no documented metastases or focal lesions at the level of the parenchyma, or lesions of vascular etiology that could explain the condition. Hepatitis B, C and HIV infection were also ruled out, and a probable Stauffer syndrome was considered. In-hospital nephrectomy was performed, with subsequent pathology compatible with clear cell carcinoma. After the procedure, liver biochemistry was normalized and jaundice was corrected. It is important to recognize that liver involvement in the context of neoplasms is not only attributed to distant metastases but to the existence of paraneoplastic syndromes as determining factors.
