RESUMO

Congenital rubella syndrome (CRS), caused by rubella virus infection during pregnancy, remains a public health concern in developing countries. Three to five per cent of all suspected CRS cases in India have been proven to be a rubella infection. Only about 45%-60% of pregnant women and infants in India receive the rubella vaccination. We present a case of a preterm female infant who tested positive for the rubella virus. The baby was born with low birth weight and, on examination, showed pallor and hepatosplenomegaly. She was detected to have an ostium secundum atrial septal defect (ASD) and a large patent ductus arteriosus (PDA) on echocardiography. On ophthalmic examination, she was diagnosed with bilateral cataract. She was treated with diuretics, and she underwent surgical correction for PDA. With this case we intend to present the literature, clinical manifestations and management of CRS. We will also focus on prevention, vaccination and disease burden in India..

RESUMO

Autoinflammatory diseases are caused by pathologic activation of the innate immune system. Primary hemophagocytic lymphohistiocytosis (HLH) is an aggressive syndrome of excessive immune activation caused by monogenic mutations resulting in cytotoxic cell defects and subsequent failure to eliminate activated macrophages. Secondary HLH is often diagnosed in cases without a known Mendelian inheritance. However, some cases of "secondary" HLH have been shown to harbor mutations with partial dysfunction of the cytotoxic system. Recently, macrophage intrinsic abnormalities caused by NLRC4 inflammasome mutations have been linked to autoinflammation and recurrent macrophage activation syndromes resembling a primary HLH. We report a case of a former 28-week preterm infant with congenital anemia, ascites, and a heavy edematous placenta with fetal thrombotic vasculopathy, who developed hepatosplenomegaly and unexplained systemic inflammation with laboratory features of HLH in the early postnatal course and died at 2 months of age. Postmortem examination confirmed the hepatosplenomegaly with marked sinusoidal hemophagocytosis, along with striking hemophagocytosis in the bone marrow and lymph nodes. There was extensive acute and chronic ischemic bowel disease with matted bowel loops, fibrous adhesions, and patchy necrotizing enterocolitis features. Whole exome sequencing analysis demonstrated a novel mosaic heterozygous NLRC4 512 C> T (p.Ser171Phe) de novo mutation predicated to cause a dominant, gain-of-function mutation resulting in a constitutively active protein. The assembly of NLRC4-containing inflammasomes via an induced self-propagation mechanism likely enables a perpetuating process of systemic macrophage activation, presumed to be initiated in utero in this patient.

RESUMO

OBJECTIVE: To determine the prevalence of cytomegalovirus in pregnant women and types of overt congenital infection in neonates. METHODS: This cross-sectional study was conducted at the Pakistan Institute of Medical Sciences and Federal Government Services Hospital in Islamabad, Pakistan, from March 2010 to June 2011, and comprised blood samples of pregnant women. Seroprevalence of human cytomegalovirus, immunoglobulin G and immunoglobulin M was determined by enzyme-linked immunosorbent assay while its deoxyribonucleic acid was detected by nested polymerase chain reaction.The congenital human cytomegalovirus infection was also identified in newborn babies from actively infected pregnant women. SPSS 18 was used for data analysis. RESULTS: Of the 409 pregnant women enrolled, 399(97.55%) were seropositive for cytomegalovirus immunoglobulinG and 52(12.71%) for immunoglobulinM, while cytomegalovirus deoxyribonucleic acid was detected in 82(20%). Of the cytomegalovirus immunoglobulinM-positive women, sera of 40(80%) had immunoglobulinG avidity >50%. The remaining 12(23%) sera had avidity assay value <50%. Among the 82(20%) infected pregnant women, 70(85.4%) were successfully followed up. Among them, the virus was isolated from 41(58.5%) newborns babies, of which 15(21%) were symptomatic while 26(47.2%) were asymptomatic. Of the former, 4(26.6%) had hepatosplenomegaly. CONCLUSIONS: Human cytomegalovirus infection in pregnant women was the main reason of congenital defects among neonates.

RESUMO

BACKGROUND: With increasing laparoscopic surgery experience and improved new vessel-sealing equipment, single-incision laparoscopic surgery (SILS) for splenectomy has emerged as an alternative to multiport laparoscopy, but the application of SILS for splenomegaly is still challenging due to technical difficulties. The aim of this study was to describe the suture suspension technique contributing to SILS for hereditary spherocytosis (HS). MATERIALS AND METHODS: A retrospective review was conducted to evaluate all SILS for splenomegaly performed by a single surgeon. On preoperative ultrasonography, the spleen size index ranged from 0.67 to 0.82. An umbilical incision was used for the placement of a multichannel single port. To provide excellent exposure of the splenic hilum, a needle with a 1-0 suture was percutaneously introduced from the left hypochondriac region and then penetrated out the anterior chest wall for suspending the enlarged spleen. Dissection was facilitated by the use of a 5-mm curved reusable grasper and a 5-mm Harmonic(®) scalpel (Ethicon Endo-Surgery, Cincinnati, OH), and the splenic vessels were ligated with 5-mm Weck(®) Hem-o-lok(®) clips (Teleflex(®), Morrisville, NC). The resected spleen was placed in an endosurgical bag, morcellated, and removed from the abdomen via the umbilical incision. RESULTS: Nine children underwent SILS during the study period without conversion to open procedures or requiring additional ports. The suture suspension technique was successfully used and markedly improved the exposure of the splenic hilum. The operative time was 122.6 ± 31.2 minutes, and the extracted spleen weight was 562 ± 74.5 g (range, 420-1260 g). No intraoperative or postoperative complications were recorded. The umbilical incision healed well with a satisfactory cosmetic effect. CONCLUSIONS: Our outcome shows the suture suspension enables safe and feasible usage of SILS for the management of splenomegaly in children with HS. More experience is needed to assess advantages and disadvantages compared with the standard laparoscopic approach.

RESUMO

Southern Belgium faces an unusual recent increase of icteric bovine aborted foetuses. In the necropsy room, the majority of foetuses presented jaundice and splenomegaly. Despite a wide range of analyses, no definitive cause of abortion has yet been established but some analysis results support the leptospirosis hypothesis. This first description of cases will help veterinary practitioners to recognize more cases and to conduct those to the laboratory for future investigations.

RESUMO

We describe 2 cases of autoimmune lymphoproliferative syndrome (ALPS), which is a rare disorder of auto-immunity, chronic persistent or recurrent lymphadenopathy, splenomegaly, hepatomegaly and hyper gamma globulinemia (1gG, 1gA). Both cases presented in neonatal period which is a rare age of presentation in this disease. A 20 days old female neonate presented with respiratory symptoms which rapidly progressed needing ventilatory support. There was hepatomegaly and no auscultatory findings in the chest. Serial CBCs (complete blood counts) showed persistent leucocytosis with predominant lymphocytosis. Her chest X-ray showed left sided consolidation which responded poorly to antibiotics. Her prompt clinical response to steroids raised the suspicion of autoimmunity and the diagnosis was established after a negative bone marrow examination for leukemia and a positive result for ALPS on flow cytometry. The second case presented with anemia, thrombocytopenia starting in neonatal period followed by persistent lymphadenopathy, hepatosplenomegaly and recurrent infections which responded poorly to antibiotics. Diagnosis was delayed due to low index of suspicion, and finally achieved with multiple radiological studies, histopathology and flow cytometry.

RESUMO

Transient abnormal myelopoiesis (TAM) is a relatively common finding in children with Down syndrome but has also been diagnosed prenatally, most often presenting with fetal hepatosplenomegaly. We report a case of TAM with hepatosplenomegaly found on ultrasound and associated with an increased amniotic fluid Δ OD 450 value. TAM is most commonly transient but can be associated with fatality and therefore should be considered in the differential diagnosis when fetal hepatosplenomegaly is found on ultrasound. Amniocentesis with chromosomal analysis and a Δ OD 450 may aid in diagnosing TAM and predicting the severity of the liver involvement.

RESUMO

We describe a case of autoimmune lymphoproliferative syndrome (ALPS), which is very unusual with regard to a clinical onset soon after birth, and a clinical picture dominated by splenomegaly, jaundice, and consumptive peripheral blood cytopenias, with minimal lymphadenopathy. Our documented close follow up demonstrated initial involvement of the spleen, followed by involvement of the bone marrow and the peripheral blood. The patient underwent bone marrow transplant and is alive and well 20 months after diagnosis.

RESUMO

Congenital thyrotoxicosis is a rare and potentially fatal illness. We report a case in a preterm infant delivered to a mother known to have autoimmune endocrine disease. Diagnosis was difficult because the infant's presenting symptoms and signs closely resembled congenital viral infection with co-existent hepatic dysfunction and coagulopathy. The associated hepatic dysfunction was so severe that liver biopsy was scheduled before the diagnosis emerged. A high degree of clinical suspicion coupled with prenatal identification of pregnancies at risk of complication by congenital thyrotoxicosis is imperative to facilitate prompt diagnosis and treatment.

RESUMO

Hereditary elliptocytosis (HE) is a common disorder of erythrocyte shape, occurring especially in individuals of African and Mediterranean ancestry, presumably because elliptocytes confer some resistance to malaria. The principle lesion in HE is mechanical weakness or fragility of the erythrocyte membrane skeleton due to defects in alpha-spectrin, beta-spectrin, or protein 4.1. Numerous mutations have been described in the genes encoding these proteins, including point mutations, gene deletions and insertions, and mRNA processing defects. Several mutations have been identified in a number of individuals on the same genetic background, suggesting a "founder effect." The majority of HE patients are asymptomatic, but some may experience hemolytic anemia, splenomegaly, and intermittent jaundice.

RESUMO

Congenital absence of portal vein (CAPV) with a systemic shunt of enteric blood is a rare malformation. Twenty-seven cases have been reported to date; with the exception of 4 patients all cases had either liver anomalies or cardiac anomalies. CAPV is usually diagnosed before the age of 18 (25/27 cases). Here we present the case of a 33-year-old woman with CAPV without further anomalies. Beside suffering from circumscript scleroderma, splenomegaly and hypersplenism, the patient was otherwise healthy. Diagnosis was based on histological findings, angiography and CT scan. The liver biopsy showed portal tracts with inconspicuous arteries and bile ducts, but with severe loss of portal vein branches and minimal proliferation of bile ductules. In addition, the perivenular sinusoids were slightly dilated with focal parenchymal atrophy. Angiography showed a missing portal vein system and a missing splenic vein with drainage of the enteric blood through dilated perisplenic and perigastric collaterals to the azygos vein system. A CT scan revealed an empty liver hilus without portal vein. Here we discuss clinical aspects of this patient, show radiologic and histopathologic findings, and compare them to other cases in the literature.
