Rare and challenging extra-axial brain lesions: CT and MRI findings with clinico-radiological differential diagnosis and pathological correlation
There are many kinds of extra-axial brain tumors and tumor-like lesions, and definitive diagnosis is complicated in some cases. In this pictorial essay, we present rare and challenging extra-axial brain lesions including neuroenteric cyst, primary leptomeningeal melanomatosis, isolated dural neurosarcoidosis, intradiploic epidermoid cyst, ruptured dermoid cyst, intraventricular cavernoma, and cavernous hemangioma of the skull with imaging findings and clinico-radiological differential diagnosis, including the pathologic correlation. Familiarity with these entities may improve diagnostic accuracy and patient management
Mapping of microbial activities in the widespread soil series of Amik Plain
Bu çalışma ile Amik Ovasında yaygın olarak yer alan toprakların mikrobiyal aktivitelerini belirlemek ve haritalandırmak amaçlanmıştır. Bu amaçla ovada yaygın olarak yer alan 11 toprak serisinden sonbahar döneminde her bir seriyi temsil edecek şekilde 5 örnekleme noktasından 0-30 cm derinlikten 3 paralelli olarak toprak örnekleri alınmıştır. Örnekleme noktalarının koordinatları el GPS’i yardımı ile kaydedilmiştir. Alınan toprak örneklerinin mikrobiyal aktivitelerini belirleme amacıyla toprak solunumu (CO2 ), dehidrogenaz enzim aktivitesi (DHA) ve mikrobiyel biyomas (MBC) analizleri gerçekleştirilmiştir. Yapılan analizler sonucu elde edilen değerler ilgili serinin temel toprak haritasındaki haritalama birimi içerisine yerleştirilerek konulu haritalar üretilmiştir. Araştırma sonuçlarına göre mikrobiyal açıdan en yüksek CO2, DHA ve MBC değerleri sırası ile 29.0 mg CO2 100gkt/24sa. Acarköy serisi, 1119 ?g TPF 10 gkt/24sa. Reyhanlı serisi ve 256 mg C/kg kt. olarak Asi serisine ait topraklarda belirlenmiştir. Aynı parametrelere ait en düşük değerler ise sırası ile 11.4 mg CO2 100gkt/24sa. Aşağıoba serisi, 392 ?g TPF 10 gkt/24sa. Acarköy serisi ve 121 mg C/kg kt. olarak Reyhanlı serisine ait topraklarda bulunmuştur.In this study, it was aimed to determine and mapping of soil microbial activities in widespread soil series of Amik Plain. For this purpose, soil samples were taken from 11 soil series (Aşağıoba, Karasu, Topboğazı, Acarköy, Comba, Reyhanlı, Sazyurdu, Asi, Keçebek, Arpahan, Akkerpiç) in the autumn period. Each will represent a series of five sampling points and 0-30 cm depth of soil samples taken from the three paralleled without waiting is subjected to analysis. Coordinates of sampling points were recorded with the help of handheld GPS. Soil respiration (CO2), dehydrogenase enzyme activity (DHA) and microbial biomass carbon (MBC) analyzes were done for the purpose of determined of microbial activity. Thematic maps were produced as a result of the analysis of the values placed basis of soil mapping units of related series. According to research results, the microbial point of the highest CO2, DHA and MBC values were determined as 29.0 mg CO2 100g.ds/24 h. in Acarköy Series, 1119 μg TPF 10 g.ds/24h. in Reyhanlı Series and 256 mg C/kg.ds. in Asi Series’ soils respectively. Belong to the same parameters of the lowest values were determined as 11.4 mg CO2 100 g.ds/24sa. in Aşağıoba Series, 392 μg TPF 10 g.ds/24h. in Acarköy Series and 121 mg C/kg.ds. in Reyhanlı Series’ soils respectively
Training interprofessional teams in geriatric emergency medicine: A modified team-based learning approach
Background: Older adults deserve special healthcare provision in every branch of medicine. Turkey currently does not have geriatric emergency medicine (GEM) subspecialty training. Thus, interprofessional training for healthcare professionals involved in GEM services is required. Team-based learning (TBL) seems suitable to implement such training. We aimed to develop and implement a training program for healthcare professionals engaged with GEM services, and evaluate the program considering teacher and learner satisfaction and knowledge retention. Methods: This was a design-based study in which a one-day GEM training program was developed based on the literature and expert opinions. The program was applied to 54 physicians, 98 nurses, 70 health officers, and 102 paramedics using a modified version of TBL. Teams included at least one representative from each profession. TBL was modified by adding a 1-h lecture and eliminating peer evaluation. Feedback forms, individual and group tests of TBL, and a retention test conducted six months later were used for program evaluation. Results: The mean group test score was higher than that of individual tests in all professions. Physicians’ individual test scores were higher than those of other professions, but this difference disappeared in the group test. The retention test mean score was higher than the individual test mean score but lower than that of the group test. Teacher and learner satisfaction was high. Conclusion: We implemented a training program using a modified TBL approach to teach GEM to relevant healthcare professionals; it yielded promising results regarding knowledge gain and retention, as well as teacher and learner satisfaction. The instruction design and method used in this study can be applied to multidisciplinary team training

Ectopic Pituitary Neuroendocrine Tumors/Adenomas Around the Sella Turcica
Functional or non-secretory ectopic pituitary neuroendocrine tumors (PitNET) can form around the sella turcica during the development of the adenohypophysis by differentiating and detaching from the pharyngeal roof. These tumors usually appear in the sphenoid sinus, clivus, cavernous sinus, infundibulum, and suprasellar cistern. Ectopic PitNETs typically display the characteristic magnetic resonance imaging findings of pituitary adenomas. However, preoperative diagnosis of PitNETs is usually challenging because of the variety of clinical and imaging presentations, locations, and sizes. Ectopic suprasellar PitNETs resemble mass lesions in the pituitary stalk. Ectopic cavernous sinus of PitNETs are typically microadenomas in the medial wall. Ectopic sphenoclival tumors are characterized by more aggressive tumor activity than the other ectopic PitNETs. Although ectopic PitNETs are exceedingly rare, they should be considered as a differential diagnosis for masses around the sella turcica. Treatment of the disease should be individualized and may include medical care, surgical resection, gamma-knife radiosurgery, and radiotherapy
Masked hypertension is associated with end organ damage in geriatric age: Geriatric MASked Hypertension and End organ damage (G-MASH-End organ Study)
Purpose: It is a question whether masked hypertension (MH) leads to end-organ damage in the geriatric age group. The aim of this study is to evaluate the associations between MH and end-organ damage such as left ventricular hypertrophy (LVH) and proteinuria in geriatric population. Materials and methods: One hundred and two patients who were admitted to the outpatient clinic were included in the study. These patients were also included in the GMASH-Cog study in 2016, which examined the relationship between MH and cognitive function. All patients underwent ambulatory blood pressure measurement procedures. Cardiac functions of all patients were determined by echocardiography. Spot urine albumin/creatinine ratio (ACR) was measured in all patients. Results: Forty four of 102 patients (43%) were diagnosed with MH. ACR was 9.61 mg/gr in the MH group and 7.12 mg/gr in the normal group (p = .021). In addition, left ventricular mass index (LVMI) was found to be higher in the MH group than in the normal group. Mean LVMI scores were 107.76 ± 16.37 in patients with MH and 100.39 ± 19.32 in the normotensive group (p = .046). Conclusion: MH is associated with end-organ damage in geriatric patients. Urinary albumin excretion and LVH which are the parameters of end-organ damage were significantly higher in MH patients. MH may cause end-organ damage and should not be overlooked in geriatric patients
