    ABSTRACT: Chronic histiocytic intervillositis of the placenta (CHI) shows monocytic/histiocytic infiltration of the intervillous space. Placental malaria has a CHI-like histopathology and induces an aberrant expression of Toll-like receptors (TLR) 3, 7-9. We hypothesized that, similar to placental malaria, CHI could be associated with increased TLR expression. TLR1-10 and other inflammation-associated factors were analyzed by real-time PCR and immunohistochemistry. A total of 31 formalin-fixed and paraffin-embedded placenta samples were evaluated: CHI (n = 9), and for control purposes, villitis of unknown etiology (VUE, n = 8) and placentas without inflammation (n = 14). CHI shows increased expression of monocytic TLR1, a receptor which is involved in bacterial lipopolysaccharide (LPS)-induced inflammation. This could indicate a TLR1-mediated immune mechanism in the placenta (e.g. triggered by transient, clinically inapparent maternal bacteraemia) which leads to massive monocytic/histiocytic accumulation in the intervillous space. The increased expression of TLR1 with no increased expression of TLR3 and TLR7-9 is different from that in malaria.

    ABSTRACT: Purpose: To evaluate the pathological features of the primary lesion in patients with relapse of unilateral favorable histology nephroblastoma. Material and methods: Fifty-eight patients with unilateral favorable histology nephroblastoma who underwent initial nephrectomy before chemotherapy were categorized into one of two groups: the nonrelapsed group (n = 52) and the relapsed group (n = 6). The histological subtypes of both groups and pathological features of the relapsed group were re-evaluated retrospectively. Results: The histological subtypes of all relapsed cases were classified as blastemal predominant. In three of six cases with relapse, sheets of spindle-shaped blastemal cells that were histologically reminiscent of synovial sarcoma were predominant (massive sarcomatoid pattern). Conclusions: The histological blastemal predominant subtype of nephroblastoma is a strong indicator of relapse. In particular, the blastemal predominant subtype with massive sarcomatoid pattern may have a higher risk of relapse.

    ABSTRACT: Noonan syndrome is a multisystem genetic disorder caused by genes encoding proteins involved in the RAS-MAPK pathway. Affected fetuses have variable presentations ranging from the absence of prenatal findings to increased nuchal fold, cystic hygromas, pleural effusions, cardiac malformations, or skin edema. We describe a male fetus who had features consistent with Noonan syndrome at the time of fetal anatomic survey, including hydrops and a possible cardiac defect. Subsequent scan revealed persistent bilateral pleural effusions (with predominance of lymphocytes). After bilateral thoracoamniotic shunt placement, the fetus did well and delivered at term. Prenatal testing revealed an S650F missense mutation in the RAF1 gene, which had not previously been associated with Noonan syndrome.

    ABSTRACT: The study aim is to evaluate the placental histopathological characteristics and maternal risk factors in preterm and term births according to their weeks of gestation. We designed a prospective study involving a patient population (n = 355) composed of pregnant women who delivered preterm (n = 216) and term neonates (n = 139). The preterm births were divided into three groups as extremely (n = 22), moderate (n = 96) and late preterm (n = 98) births. The statistical analyses were performed using SPSS version 15 software. There was significant difference regarding maternal vascular underperfusion and inflamation in the extremely preterm group compared with the other groups (P = 0.001), but fetal vascular obstruction and villitis of unknown etiology were not found significantly different. According to our study results, the careful examination of the placenta of premature babies, particularly those of extremely preterm births, should be part of routine obstetrical management to determine the causes of preterm birth.

    ABSTRACT: To investigate pancreaticobiliary ductal anatomy during developmental stages, gallbladders, common bile ducts, pancreatic ducts and their interface with theduodenum were studied in 36 human fetuses between 4-6 weeks postconceptual age were studied. For histological examination, sections were cut continuously from the paraffin-embedded tissue block and stained with hematoxylin and eosin. The expression of proliferating cell nuclear antigen in the gallbladder was examined with immunohistochemistry. Among 36 cases, three shapes of the greater duodenal papilla were found: hemispheroid (58.1%), circular cylinder (25%), and flat shape (16.9%). For the location of the greater duodenal papillas, more than half (69.4%) of the cases were in the middle descendant duodenum. Seven cases (19.4%) were in the lower descendant duodenum. Three cases (8.3%) were in the upper descendant duodenum, and one (2.9%) was in the distal descending part of duodenum. There were four types of the pancreaticobiliary ductal union: "Y" in 24 cases(66.7%), "U" in 4 cases (11.1%),"V" in 7 cases (19.4%), and pancreaticobiliary maljunction in 1 case (2.8%). For patients with congenital bile duct dilation and Biliary cancer, the positive cells of proliferating cell nuclear antigen were increased significantly (P < 0.05). Different types in pancreaticobiliary ductal union investigated in this study may provide clues for pathogenesis and clinical treatment of pancreaticobiliary maljunction.

    ABSTRACT: We herein present a case of a 14-year-old boy with the histological features of coexisting membranous nephropathy (MN) and IgA nephropathy (IgAN). Asymptomatic hematuria/proteinuria was initially detected in school urinary screening, with treatments including oral corticosteroids leading to complete remission. Cases of coexisting MN and IgAN are very rare among the pediatric population; however, the overlap of these two nephropathies does not always imply a deleterious clinical outcome in pediatric cases.

    ABSTRACT: Methods: Trials on the relationship between maternal IgG anti-A/B titers and the risk of ABO-HDN were collected by searching Embase, PubMed, and Cochrane Central Register of Controlled Trials (CENTRAL) electronic databases. The inclusion criteria were maternal IgG anti-A/B titers screening and the evaluation of clinical outcomes in relation to ABO-HDN. Stata 12.0 was used to analyze the data. Results: A total of 23 trials were eligible for inclusion, of which four trials with 5,246 participants were suitable for this meta-analysis. Meta-analysis results suggested that maternal IgG anti-A/B titers were significantly associated with the risk of ABO-HDN [OR = 2.86, 95% CI = 2.50-3.28; OR = 4.67, 95% CI = 3.92-5.55; OR = 1.61, 95% CI = 1.36-1.91 in titers (128 to 256) vs. titers (64 or lower), titers (512 or higher) vs. titers (64 or lower), and titers (512 or higher) vs. titers (128-256), respectively]. Conclusions: Our meta-analysis suggests that maternal IgG anti-A/B titers are significantly associated with the risk of ABO-HDN. They contribute to the prediction of risk of ABO-HDN, in addition to the need for invasive treatment for antibody titers ≥512.

    ABSTRACT: Pseudomonoamniotic gestations are increasingly recognized through sonographic surveillance of monochorionic twins, though etiologic factors remain undefined. We present a case of spontaneous pseudomonoamniotic twins and propose umbilical cord insertion proximity as a sonographic marker. Systematic review of the literature was performed and additional cases with similar findings were noted. Approximately 75% of reported cases (28/37) were deemed spontaneous and several included short inter-cord distances. Shunting of blood away from the membranes in the region between the cord insertions may be responsible for membrane rupture. Further investigation is needed into short inter-cord distance as a marker for monochorionic twins at risk to become a pseudomonoamniotic gestation.

    ABSTRACT: The aim of this study was to analyze abnormalities of umbilical coiling index (UCI) in twin gestation to test whether the coiling is genetically influenced by zygosity. Data retrieved comprised gestational age (GA), chorionicity, fetal gender, and UCI. The mean UCI of hypercoiled cords in monochorionic placentas was 0.55 coils/cm and 0.49 coils/cm in dichorionic placentas with discordant fetal gender (P = 0.2629). In conclusion, no significant statistical difference between UCI in monochorionic and dichorionic twin placentas with discordant fetal gender was identified, suggesting that zygosity does not play a role in umbilical coiling induction.

    ABSTRACT: Thoracoschisis is an extremely rare congenital birth defect in which intra-abdominal organs eviscerate through a defect in the thoracic wall(1). There are only seven previously reported pediatric cases and in each case, there is some diaphragmatic anomaly, suggesting that the defect took place before complete formation of the diaphragm. Our patient was referred to us from a local hospital immediately after delivery. The patient was born with a thoracoschisis of the left side below the 8(th) intercostal space. The thoracoschisis was repaired. Although there is a high prevalence of cardiac defects among thoracoschisis patients, this patient shows only small atrial septal defects.

    ABSTRACT: Confined placental mosaicism (CPM) of trisomy 16 is related to intrauterine growth restriction; however, its association with increased nuchal translucency (NT) has not been sufficiently studied. We report the first case involving a diagnosis of CPM for trisomy 16 in a dichorionic twin. Increased NT (3.7 mm) and 1 week of growth retardation at 12 weeks of gestational age were detected in the affected fetus compared with the normal fetus. Given that the biochemical analytes in maternal serum aneuploidy screening of the abnormal fetus were diluted by the presence of the normal fetus, this method was unreliable as a screening tool. Therefore, in dichorionic twins, ultrasonographic findings such as increased NT and early growth retardation can serve as important indicators for the diagnosis of CPM of trisomy 16.

    ABSTRACT: The authors present a case of 3-year-old female with Stage 4 neuroblastoma originating from the left adrenal gland. Biopsy of the left adrenal tumor showed neuroblastoma. After three courses of chemotherapy, the left adrenal gland including the left adrenal tumor was surgically removed. Pathological findings of the resected tumor revealed that most of the neuroblastoma tissues changed to pheochromocytoma-like cells. The tumor cells were arranged in well-defined nests surrounded by a delicate fibrovascular stroma and had granular eosinophilic cytoplasm, and round to oval nuclei. Immunohistological analysis of the biopsy samples showed strongly positive Ganglioside GD2-staining cells, whereas almost all of the tumor cells in the resected specimen were Ganglioside GD2-negative; cells were very weakly stained. The authors suggest that a part of the neuroblastoma in the left adrenal gland exhibited unusual differentiation toward pheochromocytic lineage Ganglioside GD2-negative neuroblastoma in a patient who had been treated with intensive chemotherapy.

    ABSTRACT: Primary cutaneous Ewing's sarcoma is a rare entity. Although the diagnosis may be very difficult, it can be confirmed through molecular biology. We present the case of a 13-years old male with a lesion in the sole of the right foot, characterized by a monomorphous proliferation of small, round and blue cells. The histology and molecular biology allowed us to perform the diagnosis of cutaneous Ewing's sarcoma. This neoplasm must be distinguished from other round cell tumors with cutaneous involvement. The prognosis and treatment of this rare disease will also be discussed.

    ABSTRACT: Livedo reticularis is a red cutaneous netlike pattern that is caused by abnormalities of the microvascularization and can be associated with many other potential systemic etiologies. We describe a case of a newborn that presented with livedo reticularis on his first day of life without any obvious systemic signs. The livedo reticularis was associated with Escherichia Coli K1 meningitis as revealed by laboratory tests. Clinical infectious signs developed a few hours later. Despite appropriate antibiotics therapy, he died on his second day because of sepsis and disseminated intravascular coagulation. Cerebrospinal fluid culture, blood culture, and culture of samples from trachea showed the presence of Escherichia Coli serotype K1 with many virulence determinants. In newborn, livedo reticularis must not be considered as physiological, but as a potential sign of unknown severe bacterial infection. Thus, the presence of livedo reticularis must require urgent laboratory tests.

    ABSTRACT: Rhabdomyosarcomas (RMS) may resemble other non-myogenic sarcomas and malignant rhabdoid tumor (MRT). Alveolar rhabdomyosarcoma (ARMS) often harbors a typical translocation, but embryonal rhabdomyosarcoma (ERMS) lacks any specific rearrangement. Histopathology is not always sufficient for an unequivocal diagnosis, necessitating ancillary studies, including immunohistochemistry (IHC). Sixteen genetically tested RMS and two MRT were xenografted and followed in successive passages. Tissue microarrays were constructed including samples from original and xenograft tumors. Desmin, myogenin, CK, EMA, INI1, LSD1, AP2β, fibrillin-2, HMGA2, nestin, and SIRT1 were tested using immunohistochemical staining. Desmin and myogenin were positive in all RMS, and the epithelial markers were negative in almost all RMS. New markers (LSD1, AP2β, HMGA2, Nestin, and SIRT1) were positive in all RMS and MRT. There were no differences in IHC expression between the three RMS subtypes tested except fibrillin-2, which was negative in ARMS. Applying new IHC markers can contribute to RMS diagnosis. Nevertheless, most markers are also expressed in MRT, and further studies are needed to confirm their value against this and other small round cell tumors.

    ABSTRACT: Limb body wall complex (LBWC) is characterized by multiple severe congenital malformations including an abdominal and/or thoracic wall defect covered by amnion, a short or absent umbilical cord with the placenta almost attached to the anterior fetal wall, intestinal malrotation, scoliosis, and lower extremity anomalies. There is no consensus about the etiology of LBWC and many cases with abnormal facial cleft do not meet the requirements for the true complex. We describe a series of four patients with LBWC and other malformations in an attempt to explain their etiology. There are several reports of fetuses with LBWC and absent gallbladder and one of our patients also had polysplenia. Absent gallbladder and polysplenia are associated with laterality genes including HOX, bFGF, transforming growth factor beta/activins/BMP4, WNT 1-8, and SHH. We postulate that this severe malformation may be due to abnormal genes involved in laterality and caudal development.
