Objectives: The role of perioperative hemofiltration (HF) in adult patients with impaired renal function undergoing cardiac surgery is controversial. There are suggestions that it may be beneficial for high risk patients undergoing prolonged cardiopulmonary bypass (CPB) surgery. However, long term outcomes in coronary artery bypass graft (CABG) surgery patients have not been investigated. Methods: To address this we retrospectively followed 7620 patients who underwent CABG between April 2001 and March 2006. Logistic regression was used to risk adjust in-hospital outcomes. Cox proportional hazards analysis was used to risk adjust Kaplan-Meier freedom from death curves. Outcomes were adjusted for American Heart Association and American College of College of Cardiology recommended variables. Results: 113 patients had intraoperative HF, 38 had postoperative HF and control group of 7006 that had no HF. After adjusting for differences in case-mix, patients with preoperative kidney disease who received postoperative HF proportionately had significantly higher rates of hospital deaths as compared with intraoperative HF patients. In addition, 5-year follow-up risk-adjusted freedom from death indicated significant differences between intraoperative HF group and postoperative HF patients. Conclusions: These findings support the hypothesis that after adjusting for differences in case mixes, the use of intraoperative hemofiltration may offer superior short term clinical outcomes and longer-term survival benefits for patients with preoperative kidney disease.

Background: Breast cancer (BC) is one of the most prevalent malignancies. BC survivors have higher risk of second primary cancers than the general population. There is an increased interest in BC survivor management, including the prevention of these second cancers. The aim of this study was to assess the risk of gynaecological malignancy (GM) as second neoplasm among BC patients in our population. Methods: Patients with invasive BC diagnosed from 1980 to 2014 included in the Girona Cancer Registry were included. The incidence of second GM in these patients was compared to those in the general population. Second primary cancer was stated as a tumour diagnosed after 2 months from the BC diagnosis. Standardized incidence ratios (SIR) and absolute excess of risk (AER) were calculated. Results: 9,717 patients were diagnosed with invasive BC during this period, with a median age at diagnosis of 61 years, and a median follow-up of 7.9 years. 117 of them developed a second GM. By tumour type, the only statistically significant higher SIR was observed for corpus uteri cancer (SIR:2.28 95% CI 1.82-2.83; AER:6.43 95% CI 4.13-9.14). After reviewing the histology of the corpus uteri cancer cases, we found that 71.4% were type I (endometrioid adenocarcinoma), 15.5% type II (serous adenocarcinomas and clear cell carcinomas), 10.7% carcinosarcomas, 2.4% sarcomas and there were no unspecified malignant neoplasms. Conclusion: BC survivors have an increased risk of corpus uteri cancer, with an increase in unfavourable histologies compared to the general population. Lifelong primary and secondary prevention interventions should be recommended for these patients.

Background: The effect of salpingectomy on ovarian response is a matter of debate. Due to conflicting data, alternative techniques were developed to perform salpingectomy for treatment of hydrosalpinges in infertile patients. This study aims to evaluate the effect of salpingectomy on ovarian response after stimulation with gonadotropins. Methods: In a retrospective analysis, one hundred fifty-seven patients with tubal infertility were divided into three groups according to their surgical histories: bilateral salpingectomy (BS group); unilateral salpingectomy (US group); and no history of salpingectomy (NS group). Ovarian response and IVF outcomes were compared between groups by analysis of variance. Prognostic factors for ovarian response were estimated by linear regression models. Results: In the BS group, the total numbers of oocytes retrieved, and embryos obtained were significantly lower than those in the NS group (p = 0.02). Poor ovarian response was also more frequent in the BS group (p = 0.02). In the US group, follicle development was reduced on the operated side. This effect was more pronounced when salpingectomies were performed for hydrosalpinges than when performed for ectopic pregnancies, and significant decreases were observed in follicle recruitment (p = 0.005) and oocyte retrieval (p = 0.02) on the operated side. Conclusion: Salpingectomy could have a minor negative effect on ovarian response. This is particularly true with bilateral salpingectomies, in which the ovarian blood supply could be disrupted, with no possible compensation by the contralateral side.

Oral cavity is the gateway of the human body, and also provides vital clues of our systemic health. Here in this COVID-19 pandemic, oral manifestations such as dysgeusia, ulcers, xerostomia are noticed and are an an important predictors of this viral disease. This short review describes the oral manifestations of this new disease.

A clinical case of treatment of two severe intrabony defects on the aesthetic zone is reported and followed for one year. The biomaterial of choice was enamel matrix derivative (Emdogain®; Straumann™) alone with a preservation papilla flap and a minimally invasive surgical technique. After surgical treatment, the patient was kept in a supportive periodontal therapy programme with 6-month interval between appointments. In the one year after surgery appointment, clinical and radiographic changes were observed, showing periodontal health and stability. 

Study design: A consecutive case series study Purpose: To investigate whether Low Back Pain (LBP) in women with primary singleton pregnancy induces disability. Background: LBP is reported to be increased in pregnants than in non-pregnant women. Different outcome measures have been used to search for correlations between pain and disability. Methods: 167 pregnant women aged 30 ± 3.5 years participated. Two equal categorial age groups were constructed: Group A included women aged 23 - 29 years, and Group B women aged 30-39 years. Their weight was 76 ± 13 kg prepartum and the Body Mass index (BMI) was 28 ± 4 prepartum. Visual Analogue Scale (VAS) was used for LBP pain intensity and Oswestry Disability Scale (ODI) for disability estimation in the last three months prepartum and in the first three months postpartum. Results: The women weight was 67 ± 13 kg postpartum. The BMI was 24 ± 4 postpartum. There was no difference in VAS and ODI scores versus BMI, weight and height between the two age groups in both periods of observation: prepartum and postpartum. Prepartum, 81.4% of women claimed LBP that dropped to 55.5% postpartum. ODI score dropped from 19.5 ± 13.6% prepartum to 11 ± 12% postpartum. The ODI subscales that showed significant reduction postpartum were: Pain intensity (P = 0.002); working (P = 0.009); sitting (P = 0.004); standing (P = 0.003); sleeping (P = 0.008); and traveling (P = 0.006). VAS prepartum was increasing as the weight was increasing in both periods of observation (P = 0.015 and P=0.051) respectively. VAS prepartum was significantly correlated with BMI prepartum (P = 0.019) and postpartum (P = 0.028). Discussion: Physical disability in pregnant women was low and reduced following delivery. Disability was linked with LBP intensity, weight, BMI and height, but not with age or educational level. 

Purpose: To evaluate changes in children with bilateral cleft lip and palate (BCLP) who premaxillary osteotomy and secondary alveolar bone grafting as compared to children with BCLP who are not indicated for surgery, and to determine variables that differentiate patients who do or do not require osteotomy. Material and methods: Twenty-four children with BCLP were included in the study: 12 who underwent osteotomy (intervention group) and 12 who had no surgery (control group). Radiographic and model values of the intervention group were compared before (T1) and after (T2) premaxillary osteotomy, and measurements were compared with those from the control group at T1. Results: Convexity, ANB (point A-nasion-point B), and maxillary depth was more diminished at T2 in children in the intervention group. Point A, anterior nasal spine, and pogonion were retroposed after surgery, and the anterior spine was higher. At T2, the upper incisors were proinclinated and intruded, and overbite was improved. Models revealed increased intermolar intercanine width as well as intrusion of upper incisor after surgery. Premaxilla and upper molars were more extruded, had a higher total maxillary height and increased extrusion of upper incisor in children who underwent osteotomy. Conclusion: After surgery, children who undergo surgery have a premaxilla that is more normalized and more level with the occlusal plane, as well as improved dental inclination. Variables that differentiate children who require osteotomy from those who do not include more extrusion and protrusion of the premaxilla, and a greater extrusion of the upper incisors.

Background: Previous studies highlighted the negative effect of premature progesterone elevation (PE) during IVF cycles on the cycle outcomes. The aim of this study was to assess the validity of progesterone level on hCG day (P4) in the prediction of IVF/ICSI cycles’ outcome. Methods: In a retrospective cohort study, all fresh cycles of 256 patients who underwent IVF or ICSI cycles in 2017 at reproductive endocrinology & infertility unit/ Obg/Gyn department at King Abdulaziz Medical city, Riyadh, Saudi Arabia, were followed up. They were started on gonadotropin medications for ovarian hyperstimulation, followed by serial transvaginal U/S and serum estrogen levels each visit. Patients having 2 or more 18mm follicles were triggered by hCG 10,000 IU and ovum pickup was done 34-36 hrs after. Data were collected on patients’ characteristics [age, BMI infertility type], cycles’ characteristics [number of follicles and endometrium thickness on hCG day, P4 and estrogen levels], rates of pregnancy and pregnancy outcomes. Receiver operating characteristic curve was applied to determine the cut-off of P4 that corresponds with a negative pregnancy test. Logistic regression analysis was used and significance was considered at p - value of ≤0.05. Results: Pregnancy rate in the study sample was 36.7%. The mean P4 level in cycles with negative pregnancy tests was significantly higher than the mean in cycles with positive tests (p = 0.018). After adjusting for confounders, significant negative association between P4 and pregnancy rate was evident (p < 0.03). The optimum trade-off of P4 for prediction of a negative pregnancy test was 1.5nmol/L. This cut-off level had a 59% sensitivity, 51% specificity and 68% positive predictive value and 10% & 15% absolute and relative risk reductions respectively. Cycles with mean P4 of ≥1.5nmol/L were significantly associated with primary infertility (p = 0.011), lower mean BMI (p = 0.009) higher mean estrogen level (p < 0.001), lower live birth rate (p = 0.048), higher abortion rate (p = 0.039), and higher ovarian hyperstimulation rate (p = 0.027). Conclusion: Premature elevation of progesterone level on the hCG day in IVF/ICSI cycles may have adversely impacted the pregnancy rate and pregnancy outcome. The cutoff point of 1.5nmol/L for this P4 was not valid in predicting pregnancy outcomes. 

Morbidly adherent placenta (MAP) includes the spectrum of placenta accreta, increta, and percreta. It is a major cause of obstetric hemorrhage. Caesarean section is main risk factor for MAP. Ultrasound scan is highly sensitive method for MAP diagnosis and sometime Magnetic resonance image is of choice. Early diagnosis timed elective planned intervention after preparation under skillful multidisciplinary team improve the outcome and minimize the morbidity. Caesarean hysterectomy, major arteries ligation, arteries embolization and leave the placenta in-situ all are choices of management. Use of Methotrexate for the placenta in-situ in MAP is still debatable. We present a case of MAP in which placenta left in- situ followed by multiple Methotrexate injection during postpartum with good outcome and acceptability.

Functional and aesthetic rehabilitation of an extremely worn dentition is one of the most challenging aspects of Prosthodontics. A thorough examination and diagnosis & selection of appropriate occlusal scheme are key factors to achieve optimal clinical outcome. Among the variety of techniques suggested in the literature, the twin-stage technique given by Hobo & Takayama has emerged as a popular choice for clinicians in recent times. Instead of the condylar path, it utilizes standard cuspal angle as the main determinant of articulation to produce predictable disocclusion in eccentric movements. It is relatively simple, does not require special armamentarium and can be incorporated easily with commonly used clinical techniques such as face bow transfer. The present case report describes the full mouth rehabilitation of a severely mutilated dentition using Hobo’s twin-stage technique to achieve a functionally and aesthetically favourable outcome.
