Abstract Abstract 4124 We reported our experience on the antifungal prophylaxis by posaconazole in patients with acute myeloblastic leukaemia (AML) who were exposed to induction chemotherapy. To validate the benefit of an antifungal prophylaxis in this kind of population, we conducted a prospective study giving posaconazole (200mg per os x 3/24h) to all AML patients hospitalized for induction in the period 2007-2008 (group I) and to compare the observed results (incidence of severe invasive aspergillosis and overall survival) with a control group (group II) which was represented by all AML patients hospitalized for induction during the period 2006-2007 and who did not received any antifungal prophylaxis. There was in total 143 AML patients and after matching on age, gender, FAB classification and molecular markers, we got 121 patients (59 males and 62 females with a median age of 55 years): 55 patients in group I and 66 patients in group II. There were 91 AML de novo and 30 secondary AML, 18 patients had good cytogenetic markers, 43 intermediate and 58 poor (2 non evaluated). According to cytogenetics plus molecular markers, we distinguished 2 groups: a good prognostic group (n=29) associating favourable cytogenetics and intermediate 1 (normal cytogenetics+ Flt3 ITD, CEBPA,NMP1) and a poor prognosis group (n=75) with unfavourable cytogenetics and intermediate 2 (17 patients were not determined). As induction chemotherapy, patients received different combinations according to protocols, age and AML characteristics. The median interval between AML diagnosis and hospitalization was 0 day (-41 – +7), 92 patients (76%) were placed in laminar air flow rooms. After induction, 100 patients achieved a CR and 2 patients died during induction period. The median duration of aplasia and of hospitalization were 28 days (7 – 91) and 37 days (22 – 101) respectively. There was no significant difference for all the above characteristics between group I and group II. Concerning posaconazole prophylaxis, the treatment was started the 1st day of chemotherapy with a median duration of 27 days (8-94): 35 patients (64%) received their prophylaxis until their discharge, 7 (13%) discontinued due to toxicity [hepatic (n=3), renal (n=1), transfer to intensive care unit (n=3)] and 13 (23%) switched to another fungal treatment because of IA suspicion (n=5), probable IA (n=2) and invasive candidosis (n=5). Results At Day32 post induction, we observed 2 probable IA (3.6%) in group I and 8 IA [possible (n=4) + probable IA (n=4)] (12%) in group II (p = 0.085). The cumulative incidence of IA in group I and II was: at day 100, 7.27% vs 15.5%, at 1 year 12.72% vs 22.72% and at 18 months 14.54% vs 24.24% respectively. The Kaplan-Myer analysis on time to death from any cause at Day 100, showed a significant survival benefit in favour of the Pozaconazole group (group I) over the control group (group II) (p=0.0023) (figure1), this difference was also significant when we adjusted the analysis only on deaths caused by IA (figure2). After a median follow-up of 8.6 months, the probability of overall survival was 92.3% at day 100, 83.5% at 6 months, 70% at 1 year, 58% at 18 months and 36% at 2 years with a significant difference between groups I and II(p=0.02). At the last follow-up, 39 patients died in the group II and 10 in the group I. Concerning the other risk factors, the multivariate analysis showed a significant impact on long term OS of age [HR= 0.103 (0.02 – 0.5) (p= 0.00029) ], cytogenetics [HR=2.524 (1.172-5.44) (p=0.0018)] and response to induction [HR=7.73 (3.579-16.7) (p=1.9e-7)]. Conclusion We showed a very important impact of anti-fungal prophylaxis in patients undergoing chemotherapy for AML especially for invasive aspergillosis, which is a risk factor to take into account in addition to age, cytogenetics and response to treatment.

Abstract Objective: To evaluate effectiveness and safety of a 5mg tadalafil daily treatment for men with erectile dysfunction (ED) and premature ejaculation (PE) and assessment of long-term follow up by persistence of improvement 2 years after stoppage of tadalafil.Materials and Methods: The study included 160 patients diagnosed with erectile dysfunction from April 2018 to June 2020. All were evaluated using the international index of erectile function questionnaire-5 (IIEF-5) to evaluate ED and intravaginal ejaculatory latency time (IELT) for PE. Patients subdivided into two equal groups. I included 80 patients treated with tadalafil 5 mg daily for 3 months, and group II included 80 patients treated with a placebo for same period. After 3 months treatment and 2 years later after stoppage of tadalafil, all patients were assessed for ED and PE using the same questionnaires. Results: The mean IELT and IIEF pretreatment were 37±11.24 s and 13.2±4.2 respectively for group I, while in group II was 35.98±10.8 s and 13.12±4.11, respectively. After 3 months of treatment, the mean value of IELT in group I showed a highly significant improvement from 37±11.24 sec to 120.5±47.37 sec (p-value < 0.001), but for group II, the mean values of IELT showed no significant improvement from baseline 35.98±10.8 to endpoint 39.43±13.6 ( p-value > 0.05). As regarding the IIEF, there was a highly significant improvement from baseline 13.2±4.2 to endpoint 20.45±4.5 in group I (p-value < 0.001) while there was no significant difference in group II from baseline 13.12±4.11 to endpoint 15±4.84 (p-value > 0.05) . 2 years later after stoppage of tadalafil , 75 patients from group I complete follow up and there was significant improvement in IELT and IIEF form base line (37±11.24) (13.2±4.2) to endpoint (98±18.3) (19.1±2.3) respectively but less than the results after 3 months treatment.ConclusionDaily Tadalafil 5 mg was effective, tolerable, and safe treatment for patients suffering from ED and PE. Long-term follow up after 2 years declared persistence of significant improvement.

Renal dysfunction is now a prevalent complication of diabetes mellitus. Therefore, this study was carried out to evaluate the remedial effects of virgin coconut oil (VCO) on renal dysfunction in diabetic rats. Fifteen albino Wistar rats were divided into 3 groups that comprise normal control group (Group I) and diabetic control group (Group II) fed with normal rat chows and a diabetic test group (Group III) fed with 10% VCO diet. Group II and Group III were made diabetic by single intraperitoneal injection of 150 mg/kg of freshly prepared alloxan monohydrate. After 72 hours of alloxan injection, fasting blood glucose was tested to confirm diabetes mellitus. After 3 weeks, the animals were anaesthetized and sacrificed to collect blood samples for renal function analysis. The creatinine, urea, and blood urea nitrogen values of Group II were significantly different from those of Group I and Group III at P<0.001. Also, there was significant difference (P<0.05) in total protein value between Group II (4.42  ±  0.47 mg/dL) and Group I (5.78  ±  0.12 mg/dL) as well as Group III (5.86  ±  0.19 mg/dL), but there was no significant difference between that of Group I and Group III (5.78  ±  0.12 mg/dL and 5.86  ±  0.19 mg/dL, resp.). Thus, VCO is effective in preventing renal damage in diabetic patients.

OBJECTIVE: The purpose of this study was to examine the changes in nitric oxide (NO) level in the nasal and paranasal sinus mucosa after exposure radiofrequency electromagnetic fields (EMF). STUDY DESIGN AND SETTING: Thirty male Spraque-Dawley rats were randomly grouped as follows: EMF group (group I; n, 10), EMF group in which melatonin received (group II; n, 10) and the control (sham operated) group (group III; n, 10). Groups I and II were exposed to a 900 MHz. Oral melatonin was given in group II. Control rats (group III) were also placed in the tube as the exposure groups, but without exposure to EMF. At the end of 2 weeks, the rats were sacrificed, and the nasal and paranasal sinus mucosa dissected. NO was measured in nasal and paranasal mucosa. RESULTS: The nasal and paranasal sinus mucosa NO levels of group I were significantly higher than those of the control group (group III) ( P < 0.05). However, there was no statistically significant difference between group II and the control group (group III) regarding NO output ( P > 0.05). CONCLUSION: Exposure to EMF released by mobile phones (900 MHz) increase NO levels in the sinus and nasal mucosa. SIGNIFICANCE: Increased NO levels may act as a defense mechanism and presumably related to tissue damage. In addition, melatonin may have beneficial effect to prevent these changes in the mucosa.

The study involved 130 patients aged 18-35 years: 70 patients with endometrial polyps (group I), 30 patients with micropolyps (group II) and 30 patients of the control group (group III). Results. According to the anamnesis of women in the I group were significantly more frequent diseases of the cervix, which corrected physical surgery methods, in particular cryodestruction. In group II, the representatives of these indicators were similar to healthy. Normal colposcopic picture met significantly less frequently in patients and I, and II group. The differences in the incidence of HPV high oncogenic risk in all groups were not statistically significant. Conclusion. Destructive methods used in the detection of any changes in the cervix are often overly aggressive, form scars and contributing to inflamaciones process. In the chain of events leading to the formation of PE, cervical pathology and its correction can take the basic place.

Abstract Background We hypothesized that 1st generation everolimus-eluting bioresorbable vascular scaffold (BVS) stent associated with less complication and less restenosis rate than everolimus-eluting stent (EES) in chronic total occlusion (CTO) recanalization guided by intracoronary imaging. Therefore, we aimed to assess the safety and performance of BVS stent in CTO revascularization in comparison to EES guided by intracoronary imaging. Our prospective comparative cross-sectional study was conducted on 60 CTO patients divided into two groups according to type of stent revascularization: group I (EES group): 40 (66.7%) patients and group II (BVS group): 20 (33.3%) patients. All patients were subjected to history taking, electrocardiogram (ECG), echocardiography, laboratory investigation, stress thallium study to assess viability before revascularization. Revascularization of viable CTO lesion guided by intracoronary imaging using optical coherence tomography (OCT). Then, long-term follow-up over 1 year clinically and by multi-slice CT coronary angiography (MSCT). Our clinical and angiographic endpoints were to detect any clinical or angiographic complications during the follow-up period. Results At 6 months angiographic follow-up, BVS group had not inferior angiographic parameters but without statistically significant difference (p = 0.566). At 12 months follow-up, there was no difference at end points between the two groups (p = 0.476). No differences were found at angiographic or clinical follow-up between BVS and EES. Conclusion This study shows that 1st generation everolimus-eluting BVS is non-inferior to EES for CTO revascularization. Further studies are needed to clearly state which new smaller footprint BVS, faster reabsorption, magnesium-based less thrombogenicity, and advanced mechanical properties is under development. We cannot dismiss the efficacy and safety of new BVS technology. Trial registration ZU-IRB#2498/3-12-2016 Registered 3 December 2016, email: [email protected]

Abstract: Papaya leaves contain several antioxidants (flavonoid, tanin, and vitamin C) which have antiatherogenic effects that may inhibit the progression of an atherosclerotic lesion. One of the risk factors causing atherosclerosis is the consumption of food containing highly saturated fatty acids e.g. lard. Low density lipoproteins (LDL) accumulate within the intima and then are oxidized (LDL-ox). This LDL-ox is ingested by macrophages, resulting in foam-cell formation (early lesion of atherosclerosis). This study aimed to find out the histological features of the aorta of wistar rats having lard diets without the addition of the papaya leaf extract; having lard diets along with the papaya leaf extract; and having lard diets followed by papaya leaf extract. This was an experimental study on 16 wistar rats divided into 4 groups: group I without treatment (negative control group), group II lard diet for 14 days (positive control group), group III lard diet with papaya leaf extract for 14 days (treatment group I), and group IV lard diet for 14 days, and then followed by papaya leaf extract for 14 days (treatment group II). It was found that the aorta of group I showed adipose cells in the intima and media layers; group II and III showed foam cells in both layers; and group IV showed foam cells in fewer numbers than group II. Conclusion: The aorta histological features of wistar rats given lard diets for 14 days, with or without papaya leaf extract, showed foam cells in the intima and media layers. Papaya leaf extraxt added to lard diets had no effect on decreasing foam cells (no protective effect), meanwhile papaya leaf extract following lard diets showed a reduction of foam cells (therapeutic effect). Keywords: papaya leaf, lard dietary, foam cells, wistar rat.   Abstrak: Daun pepaya mengandung antioksidan (flavonoid, vitamin C) yang berefek anti-aterogenik, sehingga diharapkan dapat menghambat perkembangan lesi aterosklerosis. Salah satu faktor risiko penyebab aterosklerosis yaitu makanan yang berkandungan tinggi asam lemak jenuh, antara lain lemak babi. Konsumsi lemak jenuh berlebihan dapat mengganggu fungsi sel endotel, sehingga lipoprotein berdensitas rendah (LDL) dapat masuk dan menjadi LDL teroksidasi (LDL-oks). Makrofag menangkap LDL-oks dan menjadi sel busa (lesi dini aterosklerosis). Penelitian ini bertujuan untuk mengetahui gambaran histologik aorta tikus wistar dengan diet lemak babi tanpa pemberian ekstrak daun pepaya, diet lemak babi bersamaan pemberian ekstrak daun pepaya, dan setelah diet lemak babi dilanjutkan pemberian ekstrak daun pepaya. Penelitian ini bersifat eksperimental. Subyek penelitian terdiri dari 16 ekor tikus wistar yang dibagi menjadi empat kelompok: kelompok I tanpa perlakuan (kelompok kontrol negatif); kelompok II dengan diet lemak babi selama 14 hari (kelompok kontrol positif); kelompok III dengan diet lemak babi serta pemberian ekstrak daun pepaya selama 14 hari (kelompok perlakuan I); dan kelompok IV dengan diet lemak babi selama 14 hari, dilanjutkan pemberian ekstrak daun pepaya selama 14 hari (kelompok perlakuan II). Hasil penelitian memperlihatkan gambaran histologi aorta kelompok I tampak perlemakan; pada kelompok II terdapat sel-sel busa; pada kelompok III masih terdapat sel-sel busa; dan pada kelompok IV terdapat sel-sel busa, namun dalam jumlah yang lebih sedikit dibandingkan pada gambaran kelompok II. Simpulan: Tikus wistar dengan diet lemak babi selama 14 hari, baik dengan maupun tanpa ekstrak daun pepaya, memperlihatkan gambaran histologik adanya sel-sel busa pada tunika intima dan tunika media aorta. Pemberian ekstrak daun pepaya bersamaan dengan diet lemak babi tidak berefek menurunkan jumlah sel busa (tidak ada efek protektif) sedangkan pemberian ekstrak daun pepaya setelah diet lemak babi berefek mengurangi jumlah sel-sel busa yang terbentuk (efek terapi). Kata kunci: daun pepaya, diet lemak babi, sel-sel busa, tikus wistar.

PURPOSE: This study aimed to compare patients’ satisfaction with mandibular overdentures retained by three-splinted implants versus conventional complete denture wearers during a 7-year follow-up study period. MATERIALS AND METHODS: Thirty edentulous male patients (mean age: 60 years) were carefully selected and divided into two equal groups. All patients received a new set of complete dentures. Group I patients received three implants in the anterior mandible and were connected after 3 months with bars, clips, and loaded. Group II patients received conventional complete dentures. Patients’ satisfaction was recorded for both groups at 3 weeks (baseline) and after 1, 3, 5, and 7 years. Patients were then asked to grade their overdentures/dentures on a visual analog scale and written questionnaire to evaluate their overall satisfaction. RESULTS: Satisfaction scores of Group I patients were found to be statistically significantly higher than that of Group II patients (p < 0.05) at 3, 5, and 7 years follow-up, meanwhile, no statistically significant difference was found at baseline or after 12 months. CONCLUSION: The long-term results suggest that three-implant-retained mandibular overdenture with a clip-bar attachment appears to be a successful rehabilitation strategy which is superior to conventional dentures for patients with advanced ridge resorption.

It has been shown that guineapigs can be effectively protected against re-infection by the subcutaneous inoculation of embryonated Ascaris eggs (Soulsby, 1957). The purpose of this communication is to report a successful attempt to immunize guineapigs against a lethal oral challenge dose of eggs by the intravenous inoculation of third stage larvae of A. suum.Three groups, each containing nine guineapigs, were infected with Ascaris as follows: Group I was given 10,000 eggs by mouth. Group II Was inoculated intravenously with 2,000 third stage Ascaris larvae which had been obtained from the lungs of other guineapigs on the sixth day of infection. Both groups were challenged at the same time with 250,000 eggs by mouth, along with a control group (Group III) which had no previous infection. The guineapigs in Group I were re-infected after 18 days and those in Group II after 12 days.

Objective To evaluate the utility of entheseal ultrasonography and serum COMP in the preclinical diagnosis of psoriatic arthritis. Methods 60 psoriatic patients were divided into: 30 patients with psoriasis (group I) and 30 patients with psoriatic arthritis as control (group II). They underwent independent clinical and ultrasonographic examination of both lower limbs at the calcaneal insertions of Achilles tendons. Psoriatic arthritis disease activity and severity was assessed by modified DAS28 and Steinbrockers scores. Serum levels of COMP were measured for all patients by ELISA. Results On clinical examination, no entheseal abnormalities were detected in group I while they were present in 23.3% of group II with statistically significant difference between them ( P < 0.001). Ultrasonographic entheseal abnormalities were detected in 33.3% of group I and in 46.7% of group II with no significant difference between them ( P > 0.05). Serum COMP were significantly elevated in group I and II with no statistically significant difference between them (mean ± SD 5.9 ± 3 and 6.8 ± 12 respectively, P > 0.05). Entheseal ultrasound was more specific (67%) while serum COMP was more sensitive (87%) in the preclinical diagnosis of psoriatic arthritis. Serum COMP levels were significantly correlated with CRP in both groups and with DAS28 and Steinbrockers scores in group II ( P < 0.01). Conclusion Entheseal ultrasonography and serum COMP levels may be used complementary to each other for preclinical diagnosis of psoriatic arthritis. Serum COMP seems to be promising prognostic marker for psoriatic arthritis patients.

This work assess serum levels of soluble Fas form (sFas) in patients with different stages of laryngeal squamous cell carcinoma(LSCC) to investigate its prognostic significance. We correlate its levels with the morphological changes of peripheral blood cells via buffy coat examinatin. The study population included 70 patients clinically diagnosed and pathohistologically confirmed LSCC in addition to 20 healthy controls. According to TNM classification 33(47.1%) patients were in stage I (group I) and 24(34.3%) in stage II (group II), 13(18.5%) in stage III (group III). The results revealed that the mean serum level of sFas (pg/ml) in the control group was 51.2, in group I was 66.33, in group II was 81.33 and in group III was 112.45. Statistical analysis of the mean of sFas by ELISA test in the patients' groups in comparison to the control revealed a significant increase of both group II and III in comparison to the control group (P < 0.01) but there was no significant difference (P > 0.05) between group I in comparison to either the control or group II. There was a significant difference (P < 0.05) between group I in comparison to group III. LM examination revealed massive extent of the apoptotic cells in group III when compared to both group I and group II. EM examination of the buffy coat revealed apoptotic changes, mainly in the peripheral blood mononuclear cells (PBMNCs), represented by surface membrane ruffles and blebs with clumped nuclear chromatin and vacuolated cytoplasm. In conclusion, this study may help us to better understand one of the escape mechanisms in cancer larynx. This mechanism is represented by the significant increase in both the serum level of sFas and the morphological apoptotic changes that detected in PBMNCs. Soluble Fas may contribute to the progression of laryngeal cancer. It can be used as an attractive target for anticancer therapy and may be considered as a marker of disease progression and poor prognosis in laryngeal cancer.
