Metformin kullanımının tiroid volüm ve fonksiyonlarına etkisi

İnsülin direnci ve ilişkili metabolik bozuklukların tiroid bezinde ortaya çıkardığı fonksiyonel ve morfolojik değişiklikler son dönemin sıcak gündemini oluşturmaktadır. Önceki çalışmalarda insülin direnci (ID) olan hastalarda tiroid hacmi ve nodül prevelansının artmış olduğu gösterilmiştir. Bu çalışmada metforminin tiroid hacmi ve nodül boyutu üzerine etkilerini araştırdık. ID olan yeni tanı almış obez hastalar (n: 100; 68 kadın, 32 erkek) Ağustos 2008 ile Mayıs 2010 arasında prospektif olarak takip edildi. Tüm katılımcılara metformin tedavisinden önce ve 6 ay sonra serum TSH, serbest T3, serbest T4 ve tiroid ultrasonografisi yapıldı. Metformin tedavisinden sonra ortalama vücut kitle indeksi (VKİ) ve bel çevresi (BÇ) anlamlı ölçüde azalmıştır (34.5 ± 5.1 kg/m2 iken 32.7 ± 4.8 kg/m2 ve 106.3 ± 11.8 cm iken 101.8 ± 19.0 cm, sırası ile) (BMI için P 0.5). Ortalama tiroid hacmi (22.5 ± 11.2 mL iken 20.3 ± 10.4 mL, P 0,05) . Yaşın ise sadece volüm değişimi üzerinde anlamlı etkisi olup 50 yaş üstü grubunda volüm daha fazla azalmıştı (22,4 ±11,1 mL iken 20,2±10,4 mL, p=0,006). Sonuçlar, ID olan hastalarda metformin tedavisinin tiroid hacmini ve nodül boyutunu anlamlı olarak azalttığını göstermektedir

A Case of Superwarfarin Poisoning Due to Repetitive Occupational Dermal Rodenticide Exposure in a Worker

Superwarfarin poisoning is usually due to chronic occult small-dose exposures and can easily be misdiagnosed and may lead to serious complications. The diagnosis can be confirmed by a concordant history and analyses of blood and urine specimens with the liquid chromatography with tandem mass spectrometry (LC-MS/MS) technique. Several months of continuous treatment with high doses of daily oral vitamin K, as well as other supportive measures, are warranted, especially when repeated laboratory measurements to help predict the treatment period are not available. In this paper, a case of superwarfarin poisoning due to chronic repetitive occupational dermal exposure to commercial rodenticides is presented

Evaluation Of The Achievement Of Hematologists To Transfusion Medicine Education With Self-Assessment Questionnaire In Turkey

Background: Proper clinical use of blood andblood products requires competent theoreticaland practical knowledge of transfusion medicine.The Curriculum Development and StandardDetermination System Medical SpecializationBoard is prepared Hematology SpecialistEducation Core Curriculum in Turkey. In thisstudy, we aimed to determine the access ofhematologists to the learning objectives definedby curriculum for the transfusion medicine andthe factors affecting it.Methods: Hematologists who have beenmembers of Turkish Hematology Society since2013 have been included in the study, Thesurvey questions were prepared based on thecurriculum for transfusion medicine. The studywas applied to hematologists with “surveymonkey” application. The questionnaireconsisted of a competence self-assessment withLikert scale and theoretical multiple-choiceknowledge questions.Results: Of the 213 hematologists, 54 (25%)were included in the study. Hematologists ratedtheir competences in the clinical competenceareas as 3,65 ± 0,73 (median 3,60) as “I knowbut not t a sufficient level”. The participants‘perception of competence was “I know, butnot at a sufficient level’” with an average of3.31 ± 0.84 (median3.5) in the blood bankingfield, while the average in hemapheresis andtransfusion medicine was 4.04 ± 0.63 (median4) as “enough”. In interventional procedures,hematologists stated that their vocationalcompetences were 2,79± 0,92 (median 2,93)on average as “I have an idea- I know, but notenough”. The correct answer to 13 theoreticalquestions was an average of 6,96 ± 1,89(median 7). Hematologists performing bloodrotation felt significantly more competent thanthe physicians who could not do the rotation inthe blood bank, blood banking t(52) = -3.9, p .001 , transfusion medicine and interventionalcompetence t(52) = -2.2, p = .04 . Physicianswho believed that they are sufficient in theblood banking area, were more confident intransfusion medicine r(54) = .67, p .001 andmanaging interventional procedures r(54) =.85, p .001.Conclusion: In this study, hematologistsgenerally felt more competent in subjects suchas transfusion and therapeutic apheresis,which they often think of as not having enoughknowledge in the area of blood banking.Hematologists have been more confident inthe field of transfusion medicine as their yearsof expertise increased, but they did not feelbetter equipped in the fields of blood bankingand interventional competence. The currentresults suggested that hematologists who areexpected to be the blood bank supervisors do notinternalize the area of blood banking, are notstrong in their competence, and do not want towork in this area unless they are required.In hematology education curriculum, positiverevisions in education can be achieved byrevising blood banking curriculum and learningobjectives, standardizing blood center rotationswith content and duration, and support fromonline distance education programs

Türkiye’de Müfredat Geliştirme ve Standart Belirleme Sistemi Tıbbi Uzmanlık Kurulu tarafından, Hematoloji Uzmanlık Eğitimi Temel Müfredatı hazırlanmıştır. Bu çalışmada hematologların transfüzyon tıbbı müfredatı ile belirlenen öğrenme hedeflerine ulaşımını ve bu durumu etkileyen faktörleri belirlemeyi amaçladık. Metot: 2013 yılından bu yana Türk Hematoloji Derneği üyesi olan hematologlara transfüzyon tıbbı için müfredatı esas alınarak hazırlanan anket “Survey Monkey” uygulaması ile uygulandı. Anket, Likert ölçeği ve teorik çoktan seçmeli bilgi soruları ile öz yeterlilik değerlendirmelerinden oluşuyordu. Sonuçlar: 213 hematologdan 54’ü (%25) çalışmaya katılmıştır. Hematologların yeterlilik algıları klinik yetkinlik alanlarında ortalama 3,65 ± 0,73 (ortanca 3,60) olarak “Biliyorum ama yeterli düzeyde değil”; kan bankacılığı alanında ortalama 3.31 ± 0.84 (ortanca 3.5) puan ile “biliyorum ama yeterli düzeyde değil”; hemaferez ve transfüzyon tıbbı alanında ise ortalama 4.04 ± 0.63 (ortanca 4) “yeterli” olarak ölçüldü. Girişimsel işlemlerde hematologlar mesleki yeterliliklerinin ortalama 2,79± 0,92 (ortanca 2,93) “Bir fikrim var, biliyorum ama yeterli değil” olarak ifade ettiler. 13 teorik sorunun doğru cevabı ortalama 6,96 ± 1,89 idi (ortanca 7). Kan bankası rotasyonu yapan hematologlar yapamayanlara göre kan bankacılığı t(52) = -3.9, p < .001, transfüzyon tıbbı ve girişimsel alanlarda t(52) = -2.2, p = .04 kendilerini çok daha yetkin hissediyordu. Kan bankacılığı alanında yeterli olduğuna inanan hekimler, transfüzyon tıbbında r(54) = .67, p <.001 ve girişimsel işlemlerin r(54) = .85, p <.001yönetiminde de kendilerinden daha eminlerdi. Tartışma: Bu çalışmada, hematologlar genellikle kan bankacılığı alanında yeterli bilgiye sahip olmadığını düşünürken transfüzyon tıbbı ve terapötik aferez gibi konularda kendilerini daha yetkin hissetmistirler. Hematologlar, uzmanlık yılları arttıkça transfüzyon tıbbı alanında kendilerine daha fazla güvenmeye başlarken, kan bankacılığı ve girişimsel yeterlilik alanlarında kendilerini hala yeterli donanımda hissetmiyorlardı. Mevcut sonuçlar, hematologların kan bankacılığı alanını içselleştirmediklerini, yetkinliklerinde güçlü olmadıklarını ve gerekli olmadıkça bu alanda çalışmak istemediklerini göstermiştir. Transfüzyon tıbbı müfredatının ve öğrenme hedeflerinin gözden geçirilmesi, kan merkezi rotasyonlarının içerik ve süresinin standartlaştırılması ve çevrimiçi uzaktan eğitim programları ile desteklenmesi hematoloji eğitimine olumlu katkılar sağlayabilir
