Cliff and Lorimer (1) have proposed a simple approach to thin foil x-ray analy sis based on the ratio of x-ray peak intensities. However, there are several experimental pitfalls which must be recognized in obtaining the desired x-ray intensities. Undesirable x-ray induced fluorescence of the specimen can result from various mechanisms and leads to x-ray intensities not characteristic of electron excitation and further results in incorrect intensity ratios.In measuring the x-ray intensity ratio for NiAl as a function of foil thickness, Zaluzec and Fraser (2) found the ratio was not constant for thicknesses where absorption could be neglected. They demonstrated that this effect originated from x-ray induced fluorescence by blocking the beam with lead foil. The primary x-rays arise in the illumination system and result in varying intensity ratios and a finite x-ray spectrum even when the specimen is not intercepting the electron beam, an ‘in-hole’ spectrum. We have developed a second technique for detecting x-ray induced fluorescence based on the magnitude of the ‘in-hole’ spectrum with different filament emission currents and condenser apertures.

Background: Scabies is one of the most common skin diseases in our country. It is caused by the mite Sarcoptes scabiei var hominis, which is an ecto-parasite infesting the epidermis. Scabies is highly contagious. Prevalence is high in congested or densely populated areas. Individuals with close contact with an affected person should be treated with scabicidal which is available in both oral and topical formulations. The only oral but highly effective scabicidal known to date is Ivermectin. Amongst topical preparations, Permethrin 5 % cream is the treatment of choice. Objective: To evaluate the efficacy & safety of oral Ivermectin compared to topical Permethrin in the treatment of scabies. Methodology: This prospective, non-randomized study was conducted at the out-patient department of Dermatology and Venereology of Shaheed Suhrawardy Medical College & Hospital over a period of 6 months, from August 2016 to January 2017. The study population consisted of one hundred patients having scabies, enrolled according to inclusion criteria. They were divided into two groups. group A was subjected to oral Ivermectin and the group B to Permethrin 5% cream. Patients were followed up on day 7 and 14 for assessment of efficacy and safety. Result: The mean scoring with SD in group A (Ivermectin) and group B (Permethrin) were 8.26 ± 2.22 and 7.59 ± 2.01 respectively at the time of observation. The difference between the mean score of the two group is not significant (p=0.117) the mean scoring with SD in group A and group B were 4.54 ± 2.05 and 1.64 ± 1.84 respectively at 7thdays. The difference between the mean score of the two group is significant (p<0.001). The mean scoring with SD in group A and group B were 2.68± 2.35 and .36± 1.10 respectively at 14th day difference between the mean score of the group is significant (p<0.001). Conclusion: Topical application of permethrin 5% cream is more effective and safer than oral Ivermectin in the treatment of scabies. TAJ 2020; 33(1): 41-47

Abnormal uterine bleeding (AUB) is one of the most common indications for hysteroscopy. Most of the AUB cases occur due to endometrial or myometrium pathology. Among it, endometrial polyps (EP) and chronic endometritis (CE) prevalent in reproductive age, while endometrial hyperplasia (EH) and EP dominate in perimenopause. It was determined that EP and CE are characterized with menorrhagia and metrorrhagia approximately equally, whereas EH reveals AUB with oligomenorrhoea. Verification of exact endometrial pathology by ultrasound examination is hindered, that results in deviations of ultrasound and histological diagnosis. The usage of ultrasound data and AUB’s characteristics may improve the diagnostic accuracy on preadmission period.

BackgroundA considerable proportion of GPs’ workload is dermatological. It is important to investigate what common skin conditions encountered in primary care can be self-managed, in an effort to alleviate the burden on primary care.AimThe purpose of the audit was to identify the proportion of consultations that are dermatological in nature and analyse potential for self-management by patients.MethodData was collected using the patient electronic record system (EMIS) in general practice. A search was made for all consultations from the 17 April to 15 May 2019, which included all new presenting complaints that were dermatological in nature. The criteria for self-management included advising over the counter (OTC) medication or reassurance. On the other hand, a case was deemed not self-manageable if prescription only medication (POM) was prescribed or if a referral to dermatology was made.ResultsThere were a total of 2175 consultations, where 246 (11.31%) cases were dermatological. Of the 246, 80 cases (32.5%) could be self-managed. There were 46 different dermatological presenting complaints of which the 5 most common included: rash (51 cases), dermatitis (44 cases), acne vulgaris (13 cases), moles (12 cases), dry skin (11 cases). None of the acne or moles cases could be self-managed, whereas 23%, 68.2%, 72.7% of rashes, dermatitis, and dry skin cases, respectively, could be self-managed.ConclusionCertain dermatological conditions have more potential for self-management than others. Research into teledermatology as a means of addressing patient concern and providing clinical information is important in order to reduce unnecessary consultations.
