RESUMEN
BACKGROUND: Placenta previa and placenta accreta carry significant maternal and fetal morbidity and mortality. Several techniques have been described in the literature for controlling massive bleeding associated with placenta previa cesarean sections. The objective of this study was to evaluate the efficacy and safety of the use of the cervix as a natural tamponade in controlling postpartum hemorrhage caused by placenta previa and placenta previa accreta. METHODS: This prospective study was conducted on 40 pregnant women admitted to our hospital between June 2012 and November 2014. All participating women had one or more previous cesarean deliveries and were diagnosed with placenta previa and/or placenta previa accreta. Significant bleeding from the placental bed during cesarean section was managed by inverting the cervix into the uterine cavity and suturing the anterior and/or the posterior cervical lips into the anterior and/or posterior walls of the lower uterine segment. RESULTS: The technique of cervical inversion described above was successful in stopping the bleeding in 38 out of 40 patients; yielding a success rate of 95%. We resorted to hysterectomy in only two cases (5%). The mean intra-operative blood loss was 1572.5 mL, and the mean number of blood units transfused was 3.1. The mean time needed to perform the technique was 5.4 ± 0.6 min. The complications encountered were as follows: bladder injury in the two patients who underwent hysterectomy and wound infection in one patient. Postoperative fever that responded to antibiotics occurred in 1 patient. The mean duration of the postoperative hospital stay was 3.5 days CONCLUSIONS: This technique of using the cervix as a natural tamponade appears to be safe, simple, time-saving and potentially effective method for controlling the severe postpartum hemorrhage (PPH) caused by placenta previa/placenta previa accreta. This technique deserves to be one of the tools in the hands of obstetricians who face the life-threatening hemorrhage of placenta accreta. TRIAL REGISTRATION: ClinicalTrials.gov NCT02590484 .

BACKGROUND: YKL-40 may be involved in angiogenesis in psoriasis and psoriatic arthritis (PsA). High-resolution power Doppler ultrasound (PDUS) can detect angiogenesis of synovium in PsA. AIM: To assess serum YKL-40 in psoriasis patients with or without PsA, and to correlate its levels with disease activity and high-resolution PDUS findings. METHODS: In this case-control study, 48 patients with psoriasis (26 of them also had PsA) and 30 controls were assessed by high-resolution PDUS, and assayed for serum levels of YKL-40 by ELISA. Patients were clinically assessed using Composite Psoriatic Disease Activity Index (CPDAI). Total joint score (TJS) was used to assess joint involvement in PsA. RESULTS: A statistically significant elevation was found in YKL-40 levels in psoriatics with or without PsA compared with controls (P < 0.001), as well as in PsA (group II) compared to patients without arthritis (group I) (P = 0.002). CPDAI, synovial thickness score and colour Doppler ultrasound (CDUS) score were highly significantly higher in group II vs. group I (P < 0.001). In all patients, CPDAI, synovial thickness and CDUS score were positively correlated to each other, and each of them was positively correlated to serum YKL-40 levels (P < 0.05). In either group I or II, serum YKL-40 levels correlated positively with CPDAI (P < 0.05). In group II, TJS, synovial thickness and CDUS score were positively correlated to each other (P < 0.05). CONCLUSIONS: Serum YKL-40 can be used as a new biological marker for angiogenesis and disease activity in psoriasis with or without PsA. High-resolution PDUS is a non-invasive tool for the evaluation of angiogenesis in PsA patients as well as for the detection of early synovial changes in psoriasis patients without arthritis.

BACKGROUND: Pathomechanisms of both psoriasis and atherosclerosis may involve platelet activation. Activated platelets show increased P-selectin; CD62 expression, and mean platelet volume (MPV). Impaired brachial artery flow-mediated dilatation (FMD) is related to atherosclerosis. OBJECTIVES: To determine the presence of subclinical atherosclerosis in patients with psoriasis (without overt cardiovascular complications or traditional cardiovascular disease risk factors), compared with controls. METHODS: In this case-control study, 25 patients with psoriasis and 25 age- and gender-matched healthy individuals were subjected to assessment of MPV, CD62 expression using flow cytometry, and brachial artery FMD and transthoracic echocardiography by cardiac ultrasound scanner. RESULTS: A statistically highly significant increased CD62 expression, but not MPV, was found in cases compared with controls, and in patients with moderate/severe psoriasis compared with either mild cases or controls (P < 0.001). CD62 expression was statistically significantly positively correlated with the Psoriasis Area and Severity Index (PASI) score (P < 0.001), baseline brachial artery diameter (P = 0.03) but not FMD and aortic root diameter (ARD; P = 0.03). ARD was statistically significantly higher in patients with moderate/severe psoriasis compared with controls (P = 0.017). Stepwise simple linear regression analysis revealed that PASI score was the most important factor affecting CD62 expression (P < 0.001). CONCLUSIONS: Our study showed increased atherosclerosis risk in patients with psoriasis, particularly those with moderate/severe disease, as evidenced by increased expression of platelet CD62 compared with healthy controls. Moreover, we found a positive correlation between CD62 expression and ARD (another possible marker of atherosclerosis), with positive correlation to the PASI score; the most important factor influencing CD62 expression. However, our data on MPV and FMD do not support the use of either value for diagnosing subclinical atherosclerosis in patients with psoriasis in further studies.

PURPOSE: To study the association between cyclin D1 (CCND1) polymorphic variants and acute lymphoblastic leukemia (ALL) and breast cancer cases and the possibility of having different (CCND1) polymorphic variants in the development of ALL and breast cancer. In addition, to study the association between the different CCND1 polymorphic variants and the response to induction chemotherapy in ALL cases and clinicobiological parameters in breast cancer. METHODS: We evaluated the association of CCND1 G870A polymorphism with ALL risk in 25 ALL patients and 15 healthy controls and with breast cancer risk in 30 newly diagnosed breast cancer female patients and in 25 healthy controls. Restriction Fragment Length Polymorphism (RFLP) polymerase chain reaction (PCR) was used for analysis of G870A polymorphism of CCND1 on anticoagulated whole blood of both the ALL and breast cancer cases and control groups. RESULTS: The frequency of the AA genotype was significantly increased in the ALL cases while GG genotype was significantly increased in the control group. Furthermore, there was a highly statistically significant association between the A allele in the homozygous state AA and the ALL cases. Furthermore, there was a positive risk of developing ALL when having the AA genotype and the results were highly significant for AA genotype compared to GG genotype. For breast cancer, the results revealed that there was a positive risk association for those carrying the CCND1 A allele in the development of breast cancer. CONCLUSION: Homozygosity for CCND1 A allele was associated with ALL patients and was a risk factor for ALL development, while the presence of the A allele, whether in homozygous or heterozygous state was associated with breast cancer cases and was a risk for breast cancer .Homozygosity for CCND1 G allele was associated with the control group.

BACKGROUND: Skin tags are common cutaneous lesions with an indefinite aetiology. OBJECTIVES: To assess serum leptin, insulin resistance and metabolic syndrome in different body mass index (BMI) patients with skin tags. METHODS: Three equally distributed groups of patients with multiple skin tags: 30 normal BMI, 30 overweight and 30 obese were included. Controls were age-, gender- and BMI-matched healthy subjects. Serum leptin, insulin resistance based on homeostasis model assessment of insulin resistance (HOMA-IR) and metabolic syndrome were assessed in all groups. RESULTS: Number and extent of skin tags increase with the increase in BMI. Highest leptin levels were found in obese patients, with significant differences when compared to normal BMI and overweight patients. Similar findings existed in controls. Significantly higher leptin levels were found in obese patients compared to obese controls. HOMA-IR was significantly higher in all groups of patients compared to BMI-counterpart controls. Seventy-one per cent of patients fulfilled criteria of metabolic syndrome. Number of skin tags, leptin and HOMA-IR were significantly higher in patients with metabolic syndrome compared to patients without the syndrome. Positive correlations were found between serum leptin and HOMA-IR in obese patients and obese controls. Positive correlations were also found between number of skin tags and waist circumference in all groups of patients. CONCLUSIONS: Serum leptin displays an association with obesity and insulin resistance. Assessment of HOMA-IR in patients with skin tags may serve as a useful approach for diagnosis of insulin resistance. Waist circumference is the only criteria of metabolic syndrome that correlates with number of skin tags.

We estimated pollution in Lake Edku and the Mediterranean Sea, El-Maadiya Region, with 3 aromatic amines (1-naphthylamine, 2-naphthylamine and benzidine) in the muscle tissue of fish. There were marked seasonal variations in the aromatic amine levels. We also determined oxidative stress (blood glutathione, and catalase activity) and genotoxic effects (chromosomal aberrations and urinary metabolites) in fishermen from each area. The fishermen suffered from oxidative stress and had high levels of the urinary metabolite sulfanilamide [mean (microg/mg creatinine): Lake Edku 20.7, Mediterranean 14.5, controls 5.3]. Frequencies for total chromosomal aberrations were significantly raised in the peripheral blood lymphocytes of fishermen in both areas [frequency (per 100 metaphases): Mediterranean 67, Lake Edku 45, controls 14].

Previous studies suggest that bladder cancer risk may vary with GST genotype but these results are inconsistent. The aim of this study was to explore whether GSTM1, GSTT1 and GSTP polymorphisms were associated with increased bladder cancer risk in an Egyptian population. GSTM1, GSTT1 and GSTP1 genotype frequencies were determined in bladder cancer cases (n=72) and healthy controls with no history of malignancies (n=82) using PCR-based techniques. The GSTT1*2 genotype was particularly associated with increased risk (OR 2.71, 95%CI 1.27-5.73) and the GSTM1*2 genotype to a lesser extent (OR 1.63, 95%CI 0.85-3.10). 18.1% of cases but only 7.3% of controls were GSTP1*B*B homozygotes (OR 2.38, 95%CI 0.83-6.87). The presence of two or more a priori at-risk genotypes was associated with increased bladder cancer risk (OR 2.42; 95%CI 1.47-3.97). These results suggest that polymorphisms in the GST genes are associated with increased risk of bladder cancer among Egyptians.

In patients with multiple myeloma (MM) undergoing autologous hematopoietic cell transplantation (auto-HCT), peripheral blood progenitor cells may be collected following mobilization with growth factor alone (GF) or cytotoxic chemotherapy plus GF (CC+GF). It is uncertain whether the method of mobilization affects post-transplant outcomes. We compared these mobilization strategies in a retrospective analysis of 968 patients with MM from the Center for International Blood and Marrow Transplant Research database who received an auto-HCT in the US and Canada between 2007 and 2012. The kinetics of neutrophil engraftment (⩾0.5 × 10(9)/L) was similar between groups (13 vs 13 days, P=0.69) while platelet engraftment (⩾20 × 10(9)/L) was slightly faster with CC+GF (19 vs 18 days, P=0.006). Adjusted 3-year PFS was 43% (95% confidence interval (CI) 38-48) in GF and 40% (95% CI 35-45) in CC+GF, P=0.33. Adjusted 3-year OS was 82% (95% CI 78-86) vs 80% (95% CI 75-84), P=0.43 and adjusted 5-year OS was 62% (95% CI 54-68) vs 60% (95% CI 52-67), P=0.76, for GF and CC+GF, respectively. We conclude that MM patients undergoing auto-HCT have similar outcomes irrespective of the method of mobilization and found no evidence that the addition of chemotherapy to mobilization contributes to disease control.

We investigated the effects of vinyl chloride monomer exposure on the liver of 86 workers by measuring beta-glucuronidase, arylsulfatase A, adenosine deaminase, 5'-nucleotidase and routine liver function enzymes in the sera of the workers. In 21 of them, three or more of these parameters were raised, with a significant decrease in the level of blood glutathione and a significant increase in the enzyme activity level of glutathione S-transferase. Of these 21 workers, 14 had fatty liver infiltration, 8 of whom were also suffering from liver enlargement. Also, 4 workers had liver enlargement without fatty infiltration and 3 had enlarged spleens. The study highlights the need for vigilance in environmental monitoring and medical surveillance of workers exposed to this chemical.

The activities of renal phenolsulfotransferase and arylsulfatases A and B were estimated in 400 male Swiss albino mice classified into four groups: Normal controls, Schistosoma mansoni infected group, Dimethylnitrosamine (DMN) treated group and infected treated group. The activity levels of the studied enzymes were significantly increased in all groups when compared with the control group, also the statistical analyses showed a high significant increase of the three enzymes levels in the infected treated group; when compared separately with treated or infected groups. It was concluded, therefore, that schistosomal infection is implicated in the development of kidney cancer which may arise from the pattern of hepatic mixed-function oxidase induction characterized for schistosomiasis and its temporal relationship with the procarcinogenic initiating events. Furthermore, the striking significant increase in the enzymatic activity levels of the acid hydrolases arylsulfatases due to the lesion of both cytotoxic effects of dimethylnitrosamine as well as pathological change of schistosomiasis which may play an active role in the initiation of the malignant process by detoxifying endogenous sulfated aromatic metabolites.

Leprosy is not only a bacteriological disease but also an immunological disease, in which T helper17 and CD4(+) CD25(high)FoxP3(+) regulatory T cells (T-regs), among others, may play a role. We aimed to evaluate serum levels of interleukin (IL)-17, IL-22 (Th17 cytokines), IL-10 and transforming growth factor (TGF)-ß (down regulatory cytokines) in 43 untreated leprosy patients and 40 controls by enzyme-linked immunosorbent assay, and to assess circulating CD4(+) CD25(high)FoxP3(+)T-regs in patients using flow cytometry. Patients were grouped into tuberculoid, pure neural, borderline, lepromatous, type 1 reactional leprosy, and erythema nodosum leprosum. IL-10 and TGF-ß were significantly higher in patients as compared to controls (p < 0.001), while IL-17, but not IL-22, was significantly lower (p < 0.001), with no significant difference comparing patients' subgroups. Significantly higher CD4(+) CD25(high)FoxP3(+)T-regs levels was detected in tuberculoid, type 1 reaction and pure neural leprosy, while the lowest levels in erythema nodosum leprosum (p < 0.001). TregsFoxP3 expression% was significantly lower in pure neural leprosy than other patients' subgroups (p < 0.05). T-regs/T-effs was lowest in erythema nodosum leprosum (p < 0.05). TGF-ß correlated negatively with TregsFoxP3 expression% and T-effs% (p = 0.009 and 0.018 respectively). Leprosy is associated with defective IL-17 and overproduction of IL-10 and TGF-ß. Tuberculoid, type 1 reaction and pure neural leprosy express significantly higher circulating T-regs, consistent with effector immune mechanisms activation, but with lower TregsFoxP3 expression (in pure neural leprosy). Erythema nodosum leprosum is characterized by deficient T-regs and increased TregsFoxP3 expression%. The present study pinpointed a potential role of Th17, CD4(+) CD25(high)FoxP3(+)T-regs, and probably CD4(+) CD25(+)IL-10(+) T regulatory cells 1 (Tr1), and Th3 in leprosy.

INTRODUCTION: This study evaluated the use of both gel test (GT) and flow cytometry (FC) techniques in the detection of red blood cell-bound immunoglobulin G (IgG) and, hence, the diagnosis of autoimmune haemolytic anaemia (AIHA) in cases that were negative by the conventional tube technique (CTT) direct antiglobulin test (DAT). METHODS: The study enrolled 50 clinically diagnosed AIHA patients with CTT Coombs' negative test and 55 control subjects. GT and FC were performed on both groups. RESULTS: Ninety-two percent (46/50) of patients were positive by GT. As for FC assay, the Receiver Operating Characteristic curve determined that a cut-off of 17.5% fluorescence was the best value for interpreting FC-DAT positively in the group of patients with haemolytic anaemia (100% sensitivity and specificity), while the best cut-off for mean fluorescence intensity (MFI) was 1.74, with 76% specificity and 96% sensitivity. Both mean percent fluorescence and MFI were significantly higher among patients when compared to controls (P < 0.001). FC assay results showed no statistically significant correlations with patients' laboratory data or GT grades (P > 0.05). CONCLUSION: Flow cytometry is more sensitive than GT for assessing CTT-DAT-negative AIHA. We propose that FC percent fluorescence cut-off values should be employed to determine the Coombs' negative AIHA cases.

Cisplatin is one of the most potent chemotherapeutic antitumor drugs. Oxidative stress has been proven to be involved in cisplatin-induced toxicity. Therefore, the present study was undertaken to examine the antioxidant potential of grape seed proanthocyanidin extract (GSPE) against the toxicity of cisplatin in male rats. Cisplatin treated animals revealed a significant elevation in plasma, heart, kidney and liver thiobarbituric acid reactive substances (TBARS), while the activities of antioxidant enzymes (GST, SOD, CAT and GSH-Px, and the levels of glutathione (GSH) were decreased. Aspartate and alanine transaminases (AST and ALT), creatine kinase and lactate dehydrogenase were significantly increased in plasma, while liver AST and ALT were significantly decreased. Cisplatin significantly increased the levels of plasma total lipid, cholesterol, urea and creatinine, and the relative weight of kidney. On the other hand, plasma total protein and albumin, and body weight were significantly decreased. GSPE reduced cisplatin-induced the levels of TBARS in plasma, heart, kidney and liver, TL, cholesterol, urea and creatinine, and liver AST and ALT. Moreover, it ameliorated cisplatin-induced decrease in the activities of antioxidant enzymes, and GSH, total protein and albumin. Therefore, the present results revealed that GSPE exerts a protective effect by antagonizing cisplatin toxicity.
