RESUMO

Congenital microphthalmia (CM) is a rare anomaly of the fetal orbit, results from developmental defects of the primary optic vesicle, and is characterized by a reduced eyeball volume and axial diameter. Fetal CM cases have rarely been reported. Herein, we present a case of two fetuses with bilateral CM from the same parents, diagnosed using ultrasonography (US) and magnetic resonance imaging (MRI). We found that the antepartum US and MRI measurements were smaller than the postpartum ones. Genetic testing of the parents and fetuses revealed that GL12 gene mutation may be associated with CM.

RESUMO

Ovarian cancer is one of the most common malignancies in women. Semaphorin 4D (sema 4D) is involved in the progress of multiple cancers. In the presence of estrogen-like ligands, estrogen receptors (ERα and ERβ) participate in the progress of breast and ovarian cancers by transcriptional regulation. The aim of the study was to investigate the role of sema 4D and elucidate the regulatory pattern of ERα and ERβ on sema 4D expression in ovarian cancers. Sema 4D levels were up-regulated in ovarian cancer SKOV-3 cells. Patients with malignant ovarian cancers had significantly higher sema 4D levels than controls, suggesting an oncogene role of sema 4D in ovarian cancer. ERα expressions were up-regulated in SKOV-3 cells compared with normal ovarian IOSE80 epithelial cells. Conversely, down-regulation of ERβ was observed in SKOV-3 cells. Forced over-expression of ERα and ERβ in SKOV-3 cells was manipulated to establish ERα+ and ERβ+ SKOV-3 cell lines. Incubation of ERα+ SKOV-3 cells with ERs agonist 17β-estradiol (E2) significantly enhanced sema 4D expression and rate of cell proliferation. Incubated with E2, ERβ+ SKOV-3 cells showed lower sema 4D expression and cell proliferation. Blocking ERα and ERβ activities with ICI182-780 inhibitor, sema 4D expressions and cell proliferation of ERα+ and ERβ+ SKOV-3 cells were recovered to control levels. Taken together, the data showed that sema 4D expression was positively correlated with the progress of ovarian cancer. ERα positively regulated sema 4D expression and accelerated cell proliferation. ERβ negatively regulated sema 4D expression and inhibited cell multiplication.

RESUMO

BACKGROUND: Endovascular embolization has been used to control gastrointestinal tumor bleeding. Lots of embolic agents have been applied in embolization, but liquid embolic materials such as Onyx have been rarely used because of concerns about severe ischemic complications. AIM: To evaluate the clinical efficacy and safety of transcatheter arterial embolization (TAE) with Onyx for acute gastrointestinal tumor hemorrhage. MATERIALS AND METHODS: Between September 2011 and July 2013, nine patients were diagnosed as acute gastrointestinal tumor hemorrhage by clinical feature and imaging examination. The angiographic findings were extravasation of contrast media in the five patients. The site of hemorrhage included upper gastrointestinal bleeding in seven cases and lower gastrointestinal bleeding in two cases. TAE was performed using Onyx in all the patients, and the blood pressure and heart rate were monitored, the angiographic and clinical success rate, recurrent bleeding rate, procedure related complications and clinical outcomes were evaluated after therapy. The clinical parameters and embolization data were studied retrospectively. RESULTS: All the patients (100%) who underwent TAE with Onyx achieved complete hemostasis without rebleeding and the patients were discharged after clinical improvement without a second surgery. No one of the patients expired during the hospital course. All the patients were discharged after clinical improvement without a second surgery. Postembolization bowel ischemia or necrosis was not observed in any of the patients who received TAE with Onyx. CONCLUSIONS: TAE with Onyx is a highly effective and safe treatment modality for acute gastrointestinal tumor hemorrhage, even with pre‑existing coagulopathy.

RESUMO

BACKGROUND: Transarterial chemoembolization (TACE) has been used to treat unresectable massive hepatocellular carcinoma (HCC). Lots of embolic agents have been applied in embolization because of it can decrease patient discomfort and side‑effects. AIM: The aim was to evaluate the clinical efficacy and safety of TACE with lipiodol and gelatin sponge. MATERIALS AND METHODS: A total of 109 patients with massive HCC (the size of tumor >10 cm and unresectable) from January 2011 to August 2014 in our institution was divided into group A and group B based on the different embolitic agents. Before and about 1‑month after each case of TACE, clinical and biological data such as tumor size, child‑pugh stage, serum Alpha‑fetoprotein (AFP), complications, were recorded at the same time. RESULTS: In group A, the diameter of the tumor reduced from 12.57 ± 1.26 cm to 9.04 ± 0.89 cm. No patient was complete response (CR), partial response (PR) 36, stable disease (SD) 7 and PD 6; in group B, the diameter of tumor decreased from 12.08 ± 1.42 cm to 8.43 ± 1.05 cm, CR 0, but PR 27, SD 18 and PD 15. RR in group A was significantly higher than in group B (P < 0.05).The change of child‑pugh stage and AFP pre‑ and post‑operative in group A can be found significantly better than in group B. CONCLUSIONS: TACE with lipiodol and gelatin sponge is a highly effective for massive HCC.

RESUMO

This study explores what constructs are associated with parent-adolescent communication about AIDS/sexually transmitted infections (STIs) and sexual relationships in Nigeria. The analyses use data from the 2007 National HIV/AIDS and Reproductive Health Survey on 2593 men and women who had at least one child over the age of 12 years. The respondents were classified as low; medium; or high communicators. Low communicators were parents who did not talk to their child about either AIDS/STIs or sexual relationships. Medium communicators were parents who discussed only one topic with at least one child. High communicators were parents who discussed both topics with at least one child. Logistic regression was used to compare high communicators with low/medium communicators. There are commonalities and differences among men andwomen in the factors associated with parent-adolescent communication. Age; religion; and knowing where to obtain information about HIV/AIDS were associated with the extent of communication; regardless of the parent's gender. Perceived social support was an important correlate for fathers; while knowledge of female STI symptoms showed a significant association only for mothers. Programmatic and communication implications of the findings include addressing men and women differently; developing strategies to specifically reach younger parents and Muslims; and increasing general awareness of HIV/AIDS information resources. Further research is needed to understand the context; content; and timing of parent-adolescent conversations about AIDS/STIs and sexual relationships and how these factors affect the sexual behaviors of adolescents

RESUMO

The objectives of this study were to determine the effect of tumor necrosis factor alpha (TNF-á) on intestinal epithelial cell permeability and the expression of tight junction proteins. Caco-2 cells were plated onto Transwell® microporous filters and treated with TNF-á (10 or 100 ng/mL) for 0, 4, 8, 16, or 24 h. The transepithelial electrical resistance and the mucosal-to-serosal flux rates of the established paracellular marker Lucifer yellow were measured in filter-grown monolayers of Caco-2 intestinal cells. The localization and expression of the tight junction protein occludin were detected by immunofluorescence and Western blot analysis, respectively. SYBR-Green-based real-time PCR was used to measure the expression of occludin mRNA. TNF-á treatment produced concentration- and time-dependent decreases in Caco-2 transepithelial resistance and increases in transepithelial permeability to the paracellular marker Lucifer yellow. Western blot results indicated that TNF-á decreased the expression of phosphorylated occludin in detergent-insoluble fractions but did not affect the expression of non-phosphorylated occludin protein. Real-time RT-PCR data showed that TNF-á did not affect the expression of occludin mRNA. Taken together, our data demonstrate that TNF-á increases Caco-2 monolayer permeability, decreases occludin protein expression and disturbs intercellular junctions.
