Effect of limestone as a substituent on the physicochemical characteristics of Portland cement and mortars

Hardened cement pastes were made with and without limestone as a partial substituent of ordinary Portland cement and using the standard water of consistency suitable for each blend. The effect of the limestone as a partial substituent of Portland cement on the physicochemical and mechanical properties of the various blended cement pastes was reported. The results obtained were discussed on the basis of the chemical composition and physical state of the hydration products of the various pastes investigated as well as their initial porosities as controlled by the initial water/cement ratios

Factors affecting Premenstrual Tension Syndrome [PMS] and the value of pyridoxine in its management

This study included 230 females with premenstrual tension syndrome [PMS] compared to 250 females forming the non-PMS group. The results show that educational level, working condition, marital status, parity and contraceptive methods are all involved in the development of PMS. The diagnosed symptoms of premenstrual tension were more common among singles, students, secondary and highly educated females and married women with one or two pregnancies, who use the IUD as a contraceptive method and have breast fed. These factors provide the patient criteria to allow for early intervention to control further complications and to carry out early measures for prevention. The double blind placebo-controlled part evaluated pyridoxine as a treatment for PMS. Pyridoxine did not relieve the symptoms to a statistically significant level, nor did it significantly affect the level of patient's serum prolactin

Risk factors of cancer cervix among Kasr El-Eini and Ein Shams Hospital patients

The various risk factors for cancer cervix were evaluated in the hospital based case-control study which comprised 576 Egyptian cancer cervix patients and 1025 matched controls. The mean age at presentation was 48.2 years. The relative risk increased with the number of pregnancies, being highest in women who had 6 or more pregnancies. The age at first marriage was found to be inversely related to the risk, and the age of 17 or less at first marriage was associated the highest risk. Herpes Simplex virus, Human Papilloma virus, and Chlamydia Trachomatis were also associated with the highest relative risk. The group using tubal ligation for contraception was found to be at the highest risk. The risk of developing cervical cancer was also highest for women with irregular menses

Outpatient treatment of haemorrhoids with bipolar diathermy coagulation

A prospective study to assess the results following the bipolar diathermy coagulation for treatment of haemorrhoids was carried out in Kasr El Aini Hospital as an outpatient procedure. 52 patients complaining of 1st, 2nd and 3rd degree [19, 22 and 11 cases respectively] were subjected to one or two sittings of the bipolar diathermy coagulation All 4th degree cases, external hacmorrhoids or patients associated with any other pathology were excluded. 31 cases were males and 21 were females [ratio 1.5: 1]. Age of the patients ranged from 17 to 78 years with a mean 42 years. Follow up for the cases was done up to one year. Bleeding was the commonest presentation [46 cases, 88%] followed by discharge [22 cases, 42%]. 44 patients were relieved from their symptoms, 32 patients after one sitting and 12 after two sittings. The remaining 8 cases failed to achieve relief after 2 sittings of treatment and required formal haemorrhoidectomy. All the failed cases were of the third degree. Bipolar diathermy is a painless method to treat early- haemorrhoids [1st and 2nd degrees], easy to do, safe and with no need for hospital stay. Also it is likely to be less expensive and so it is to be recommended
