Epidemiology of breast cancer in women based on diagnosis data from oncologists and senologists in Algeria.

BACKGROUND: Breast cancer (BC) is a major health issue threatening women's life. No reliable epidemiological data on BC diagnosed by oncologists/senologists are available in Algeria. METHODS: The BreCaReAl study, a non-interventional prospective cohort study, included adult women with confirmed BC in Algeria. Disease incidence, patients and disease characteristics, treatment patterns, and mortality rate were recorded up to 12 months of follow-up. RESULTS: Overall, 1,437 patients were analysed: median age was 48 [41;57] years and 337 (23.5%) women had a family history of BC. BC incidence was 22.3 (95% CI: 21.5; 23.2) cases per 100,000 inhabitants over 8 months. Delayed diagnosis was reported in 400 (29.2%) patients. First line of treatments were mainly chemotherapy and surgery. Twenty-eight serious adverse events were reported including 10 (37.0%) events which led to death. Mortality rate reached 3.2% at 12 months CONCLUSION: A delayed diagnosis highlights the importance of implementing more effective screening strategies.

Using RT-PCR and glutathione level to study the effect of follicular fluid on in vitro maturation and gene expression of sheep oocytes.

The aim of this study is to evaluate the effect of sheep follicular fluid (SFF) supplementation of the in vitro maturation (IVM) media of sheep oocytes on the resumption of meiosis, glutathione (GSH) level, and expression of apoptosis (Bax, Bcl-2) as well as heat shock protein beta-1 (HSPB1) genes. Sheep ovaries were collected from the central slaughterhouse of Riyadh city, KSA. Oocytes were aspirated from 3 to 8 mm follicles. Sheep oocytes were cultured in maturation medium with different concentrations of sheep follicular fluid: 0% (control), 10%, 20% and 40% for 24 h. The results indicated that the maturation rate of oocytes was significantly (p ≤ .05) decreased in 40% SFF (36.87%) versus the control (61.3%), 10% SFF (63.95%) and 20% SFF (64.08%). The supplementation of the IVM medium with 10% SFF induced an intra-oocyte GSH concentration that was significantly higher than in sheep oocytes cultured with 20% and 40% SFF and similar to the GSH content in oocytes cultured without SFF. Real-time polymerase chain reaction analysis of gene expression revealed no significant differences in the Bax and HSPB1 genes between the control and 10% SFF, whereas they were significantly higher in 40% FF (p ≤ .05) compared to the control. The expression of Bax:Bcl-2 was significantly higher in 20% and 40% SFF compared to the control group. In conclusion, the addition of SFF to the IVM culture of sheep oocytes is recommended to support nuclear maturation and increase oocyte competence.

The effectiveness of misoprostol or dinoprostone in neonatal outcome after labour induction in post-term nulliparas.

OBJECTIVE: The object of this study was to investigate the efficacy of vaginal administration of misoprostol versus dinoprostone in neonatal outcome. MATERIALS AND METHODS: The first Group A included 77 pregnant women, who requested pregnancy termination one week after labour term and received vaginally misoprostol 50 µg, while the other 69 pregnant women in Group B were vaginally administrated three mg dinoprostone. According to the authors' protocol this procedure was repeated after six hours for a maximum of two times. RESULTS: The labour duration was longer in Group B (p = 0.000), while the APGAR score was better in Group A (p = 0.015). In Group A the labour modus was as follows: 86.9% normal vaginal labour, 3.8% vacuum extraction, and 9.3% cesarean section, while in Group B it was 82.83% normal vaginal labour, 3.07% vacuum extraction, and 14.1% cesarean section. CONCLUSION: Misoprostol has advantages according to neonatal outcome compared to administration of dinoprostone.

The contribution of laparoscopy to the diagnosis of adnexal masses in young and premenopausal women.

The purpose of this retrospective study was to investigate the contribution of laparoscopy to the diagnosis of adnexal masses in young and premenopausal women, in whom surgery was deemed necessary, between the years 2002-2008. A total of 130 young and premenopausal women scheduled for surgery for an adnexal mass with a diameter of 5-10 cm underwent transvaginal ultrasound (US) examination prior to surgery. Laparoscopic management was successfully completed for 118 of the 130 patients in this study; however, 12 required conversion of laparoscopy to laparotomy due to endometriosis with extensive bowel adhesions, or suspected ovarian malignancy and peritoneal implants. One hundred and twenty-four patients (95.38%) had benign lesions, four (3.07%) had borderline tumors and two patients had malignant lesions (1.53%). We found a statistically significant association between laparoscopic and histological findings. Laparoscopic diagnosis of adnexal masses suspicious at US may help avoid many laparotomies for the treatment of benign ovarian disorders.

The contribution of anaesthesia modus on reducing blood loss during caesarean section.

The purpose of this study was to compare the effects of general anaesthesia (GA) and regional anaesthesia (RA) on the blood loss during caesarean section. We report on 161 patients undergoing both elective and emergency caesarean section at the Obstetrical Department of Democritus University of Thrace. In the majority (113 women, 70.2%) GA was used, while in 48 women (29.8%) RA was used. No significant differences were found in the demographic characteristics of the study women in the two groups. Although the preoperative Hgb and Hct levels did not differ significantly in the two groups RA vs GA, the postoperative Hgb and Hct levels were significantly lower in women who were subjected to GA compared to those who were subjected to RA (p < 0.05). The study showed that there is greater reduction in blood loss with RA compared to GA during caesarean section.

Case report: Denys- Drash syndrome.

BACKGROUND: Denys-Drash Syndrome (DDS) is an uncommon disorder that appears sporadically and in rare cases may be inherited as an autosomal dominant trait It manifests either at birth or within the first year of life and typically consists of the triad of congenital nephropathy, Wilms tumour and intersex disorder. CASE REPORT: A 10 year-old Caucasian girl was referred to the Dental Department, at Glasgow Royal Hospital for Sick Children by her Paediatric Nephrologist Consultant. The patient was being teased by her peers over her markedly discoloured teeth. The dental history revealed that the patient was a regular dental attendee from an early age. She was dentally anxious having only experienced dental treatment under general anaesthesia (GA) when she was 4 years old. Apparently her primary dentition also showed a generalised discolouration. TREATMENT: This consisted of multiple visits for diet analysis and tooth brushing instruction with the use of disclosing tablets. Plaque control significantly improved when using a battery operated toothbrush because of its larger handle which the patient found easier to use and a 0.05% sodium fluoride mouthwash was given for daily use. Dyract(AP) veneers directly bonded onto maxillary permanent incisors and mandibular permanent anterior teeth was carried out. This was an interim measure to improve the patient's appearance while assessing the patient co-operation. The compomer facings were replaced with BelleGlass NG veneers which were cemented onto the maxillary incisors and mandibular anterior teeth using Adhesive By Choice (ABC) system under rubber dam on two separate visits. FOLLOW-UP: At her last visit, 27 months after treatment, the patient was still satisfied with the restorative treatment. However, further teeth had erupted including all the premolars. BelleGlass NG crowns were indicated. It was also decided to replace the preformed chrome cobalt crowns with full coverage BelleGlass NG crowns.

Systematic review of studies comparing the anti-caries efficacy of children's toothpaste containing 600 ppm of fluoride or less with high fluoride toothpastes of 1,000 ppm or above.

OBJECTIVE: To determine the clinical effectiveness of low fluoride (F) toothpastes, containing 600 ppm or less, with toothpaste containing 1,000 ppm or more fluoride in preventing dental caries. DESIGN: Systematic review of randomised controlled trials comparing low fluoride toothpastes containing 600 ppm F or less with toothpastes containing 1,000 ppm or more in children or adults. RESULTS: Seven randomised controlled trials were included. These were categorised into two groups depending on the fluoride concentration in the low fluoride group (250 and 500 ppm) and analysed separately. 250 PPM: Results of the meta-analysis were statistically significant (p = 0.002 and 0.0005) and in favour of the control group (1,000 ppm). DFS increments in the 250-ppm group were 0.6-0.7 greater than the 1,000-ppm group. 500 PPM: Only two studies were in this category, and one of them failed to present the baseline caries levels, so a meta-analysis was not carried out. CONCLUSION: 250 ppm fluoride dentifrice was not as effective in caries prevention in permanent dentition as dentifrice containing 1,000 ppm F or more. More studies have to be carried out to test the anticaries efficacy of 500 against 1,000 ppm and above.

Post-extubation atelectasis in ventilated newborn infants.

Post-extubation atelectasis (PEA) constitutes the commonest cause of lung collapse in ventilated neonates. The clinical and radiological features of 47 ventilated infants who developed PEA within 24 h of extubation are reported. Three main radiographic patterns of atelectasis were identified: (1) transient unilobar collapse resolving within 12 h of extubation (19 cases), (2) multilobar atelectasis developing over a 48-h period (18 cases), and (3) progressive atelectasis resulting in complete collapse of a whole lung. A similar number of ventilated infants without PEA served as controls. We found a significant association between the incidence of PEA and multiple intubation (P < 0.02), presence of patent ductus arteriosus (P < 0.001) and neonatal sepsis (P < 0.05). Prophylactic physiotherapy is recommended for ventilated infants, particularly those with the above risk factors.

Neonatal phrenic nerve paralysis resulting from intercostal drainage of pneumothorax.

Four cases of phrenic nerve paralysis complicating chest tube placement in the newborn for pneumothorax are presented. This complication is related to abnormal location of the medial end of the chest tube. It is suggested that on the frontal chest radiograph, the medial end of the chest tube should be no less than 1 cm from the spine.
