Mitomycin-C, first found its way into ophthalmic use in 1969, in Japan, where recurrent pterygia were successfully treated with the drug which is an antineoplastic / antibiotic agent isolated from the soil bacterium Streptomyces caespitosus [1]. It is an anti-metabolite with anti-proliferative effect on cells showing the highest rate of mitosis by inhibiting DNA synthesis and interferes with RNA transcription and protein synthesis [2].CLINICAL USES

The linear no-threshold hypothesis (LNT)-the basis of radiation regulatory policy-extrapolates from observed high-dose harm to assumed low-dose harm, entailing that all ionizing radiation is harmful, by denying any biological response to damage and asserting cumulative lifetime harm, regardless of dose or dose rate. All aspects of LNT are demonstrably false. There are evolved biological responses that repair or remove radiogenic damage from low doses and dose rates, thereby averting acute harm and precluding the alleged cumulative damage. LNT and its offspring, the “as low as reasonably achievable” principle, do not err on the side of caution; neither is truly conservative. The public needs protection from radiophobia, rather than from low-dose radiation exposure. Neither radiation regulations nor medical practice should be based on LNT, but rather, at least as a first step, on a linear (down to a) threshold (LT) model.

According to recent guidelines, endovascular angioplasty is the standard treatment for TASC A and B primary aorto-iliac occlusive (AIOD) disease, and the first-line approach for TASC C lesions [1,2]. Extended TASC D occlusive disease is usually treated by open surgery yielding excellent patency rates at a cost of a higher mortality (2%-4%) and a severe morbidity (up to 10%) [3]. However, several studies have reported promising results after endovascular treatment of extensive AIOD and full reconstruction of the aortic bifurcation [4,5]. In a recent meta-analysis, Jongkind et al., concluded that endovascular treatment of extensive AIOD can be performed successfully by experienced interventionists in selected patients [6]. Although primary patency rates seem to be lower than those reported for surgical revascularization, reinterventions can often be performed percutaneously yielding a secondary patency comparable to surgical repair.

Acute carbon monoxide (CO) poisoning is caused by the inhalation of large quantity of CO within short time leading to morbidity and mortality. In this study, a total of eighteen (18) rabbits were divided into three (3) groups of six (6) animals each. The first group first group was poisoned with CO and labelled carbon monoxide death (CD). The second group of animals was killed prior to exposure to CO and labelled disguised death (DD), while the third was the control group (CG). The vitreous humour samples were collected from all the animals using standard methodologies. The vitreous humour total protein and albumin were estimated while its globulin content and albumin/globulin ratio were derived mathematically. Pearson correlation analyses were used to establish relationships between vitreous protein profile components and the acute graded carbon monoxide concentrations. Results indicated a significant increase (P<0.05) in vitreous total protein and globulin of the studied groups. This observation was more pronounced in the CD group of animals. Therefore the marked elevation of vitreous total protein and globulin may serve as a useful tool in the confirmation of death due to carbon monoxide poisoning.

We know that until today no experiment observation has shown the existence of Supersymmetric particles [1] or additional dimensions.

Introduction: Fractures of both the anterior and posterior pelvic ring are common injuries in polytrauma and the elderly that extend beyond those of simple low-impact trauma. While conventional X-rays predominantly show the ventral aspect of the injury, computed tomography often detect additional fractures of the sacrum. A large number of these fractures are B-injuries by AO, mainly compression fractures at an advanced age. In addition, the prevalence of pelvic insufficiency fractures caused by osteoporosis rather than subsequent to an obvious trauma is increasing, with such an injury often associated with pain that impairs mobilization. The standard sacroiliac screw fixation is often characterized by loosening and thus failure of the osteosynthesis especially in osteoporotic bone of elderly patients. Method: A new alternative surgical minimal invasive technique, the “iliosacral bridging”, stabilizes the fractures of the sacrum with an internal fixation from S1 pedicle of the uninjured side to the ilium on the affected side. The combination of this internal fixation with the standard single sacroiliac screw on the injured side allows an immediate full weight bearing and pain free mobilization. We present a case series of 8 patients. Results: The clinical and radiological analysis analogous to the pelvic-outcome-score brought forward that 2 patients showed an excellent and 2 patient a good result. The other 4 patients achieved sufficient results. Conclusions: The “iliosacral bridging” we have introduced in the present study provides evidence of an expected increased stability of the pelvis after B-injuries

The study aimed to identify possible environmental risk factors for breast cancer among women in Gaza Strip and conducted in 2010. A case- control study design was used with face to face interviews by structured questionnaire with breast cancer patient women as well as healthy women. Statistical Package of Social Science (SPSS) was used to analyze the collected data. The study population was 288 women, 144 were women with breast cancer (cases) and 144 were healthy women (controls) with response rate 100% for cases as well as controls. The study was carried out in the two main hospitals in Gaza Strip (El-Shifa and European Gaza) and on cases who had a regular follow up in each hospital, while controls have been chosen from women who had no history of breast cancer by mammogram or by self-examination. In this study the main statistically significant risk factors were; marital status, educational status, physical trauma on breast, medication for infertility treatment, eating red meat 500g or more weekly, eating canned food, eating chicken skin, eating raw and cooked vegetables, using oils with saturated fats in cooking, living in or beside a farm, dealing with crops with naked hands, working in a farm during pesticides application or during 24 hours of pesticides application, cleaning pesticides’ equipment, living with people working in a farm or a agricultural field, and application of pesticides personally. In contrary, no statistically significant differences were found between cases and controls in relation to area of residency, exposure to X-ray in the past, having radiation therapy, getting contraceptive pills, using hair dyes, using anti-deodorant underarm, using facial cosmetics, using hair removal ointment, washing vegetables and fruits, buying and transporting pesticides, and wearing protective tools during pesticides mixing and application.

Purpose: To evaluate the efficacy of ranibizumab in hastening the recovery of acute CSCR when given immediately at time of diagnosis. Methods: In This retrospective case series, a total of 72 patients diagnosed with acute CSCR where reviewed, of which 63 received Ranibizumab at presentation. The patients were evaluated using Best corrected visual acuity, Ophthalmic examination, Optical coherence tomography (OCT) and fluorescein angiography, in addition to indocyanine green angiography and OCT angiography in some cases, at presentation, one week, one month and two months’ post injection. Results: From the total 72 patients diagnosed with acute CSCR, 63 of them received intravitreal ranibizumab and the remaining 9 patients preferred to go for observation. The mean age of patients was 41.2 year old. The ratio of male to female was 8:1. The mean BCVA at presentation was 6/15 on Snellen chart. All patients who received ranibizumab injection showed an improvement after 1 week, with a mean improvement in BCVA of two lines. Of them, 43 patients were back to BCVA of 6/6 after 2 months and showed complete resolution of sub retinal fluid. The remaining 20 patients showed an additional mean of improvement of one line (over the previous two lines) after the 2 months. Conclusion: Intravitreal ranibizumab hasten the recovery of both the BCVA and central macular thickness on OCT in acute CSCR when given immediately at presentation.

Potter syndrome (PS) is a term used to describe a typical physical appearance, which is the result of dramatically decreased amniotic fluid volume secondary to renal diseases such as bilateral renal agenesis (BRA). Other causes are abstraction of the urinary tract, autosomal recessive polycystic kidney disease (ARPKD), autosomal dominant polycystic kidney disease (ADPKD) and renal hypoplasia. In 1946, Dr Edith Potter characterized this prenatal renal failure/renal agenesis and the resulting physical characteristics of the fetus/infant that result from oligohydramnios as well as the complete absence of amniotic fluid (anhydramnios). Oligohydramnios and anhydramnios can also be due to the result of leakage of amniotic fluid from rupturing of the amniotic membranes. The case reported below, concerns of stillborn boy with potter syndrome.

During the last three decades, there has been an interesting debate on the intake of A1 ‘like” milk and incidence of type 1 diabetes (T1D) in genetically predisposed individuals. The epidemiological, ecological and case-control studies have concrete pieces of evidences in favor of the hypothesis that is further supported by animal trials in mice and rat and in vitro trials on cell lines. But on the other hand, European Food Safety Authority reported that there isn’t sufficient data to draw a final recommendation at this stage in terms of contradictory results, lack of cause-effect relationship and being a mere suggestive evidence [1]. However, the report itself states that these studies are strong enough to formulate a concrete hypothesis and further research is needed to confirm the same. Keeping in view the published data in favor of the hypothesis and the counter-arguments, it is suggested that further research with well-designed animal and in vitro trials with intact proteins and peptides is needed to fully confirm the hypothesis. Until the issue is fully resolved, it’s the personal choice of the individuals at risk to T1D (genetically predisposed) to either remove A1 “like” or increase the A2 “like” milk from their diet.
