Yttrium-90 distribution following radiosynoviorthesis of the knee joint in rheumatoid arthritis patients : a SPECT/CT study
Objective
To examine yttrium-90 distribution 1 and 72 h following its injection into a knee joint in patients with rheumatoid arthritis (RA).
Methods
In 14 RA patients we injected yttrium-90 into the affected knee joint using lateral approach. To assess the radioisotope distribution in the joint, the superimposed sequential SPECT and CT imaging was performed 1 and 72 h after the injection. We analyzed the percentage of radioisotope distribution in three predefined compartments of the knee joint (lower, upper medial, upper lateral).
Results
After 1 and 72 h, the mean percentage distributions were, respectively, 7.14 and 23.07 % in lower; 21.42 and 15.38 % in upper medial, and 71.42 and 61.53 % in upper lateral compartment. The percentage of isotope deposition did not change significantly with time in any of the compartments (all p > 0.26). The deposition of isotope, both at 1 and 72 h, was significantly greater in upper lateral compartment, where the injection was performed, than in all other compartments (all p < 0.05).
Conclusions
Using the SPECT/CT hybrid method, we proved that the majority of isotope is located at the compartment adjacent to the injection. Two injections targeting different compartments might improve the clinical efficacy of the procedure
Post臋powanie w chorobach tarczycy u kobiet w ci膮偶y
The management of thyroid disorders during pregnancy is one of the most frequently disputed problems in modern endocrinology. It is
widely known that thyroid dysfunction may result in subfertility, and, if inadequately treated during pregnancy, may cause obstetrical
complications and influence fetal development.
The 2007 Endocrine Society Practice Guideline endorsed with the participation of the Latino America Thyroid Association, the American
Thyroid Association, the Asia and Oceania Thyroid Association and the European Thyroid Association, greatly contributed towards uniformity
of the management of thyroid disorders during pregnancy and postpartum. Despite the tremendous progress in knowledge on
the mutual influence of pregnancy and thyroid in health and disease, there are still important areas of uncertainty. There have been at
least a few important studies published in the last 3 years, which influenced the thyroidal care of the expecting mother. It should also be
remembered that guidelines may not always be universally applied in all populations with different ethnical, socio-economical, nutritional
(including iodine intake) background or exposed to different iodine prophylaxis models.
The Task Force for development of guidelines for thyroid dysfunction management in pregnant women was established in 2008. The expert
group has recognized the following tasks: development of the coherent model of the management of thyroid dysfunction in pregnant
women, identification of the group of women at risk of thyroid dysfunction, who may require endocrine care in the preconception period,
during pregnancy and postpartum – that is in other words, the development of Polish recommendations for targeted thyroid disorder case
finding during pregnancy, and the development of Polish trimester-specific reference values of thyroid hormones.
Comprehensive Polish guidelines developed by the Task Force are to systematize the management of the thyroid disorders in pregnant
women in Poland.

Powszechnie wiadomo, 偶e dysfunkcja tarczycy mo偶e by膰 przyczyn膮 zaburze艅 p艂odno艣ci, a nieleczona prawid艂owo w czasie ci膮偶y zwi臋ksza
ryzyko powik艂a艅 po艂o偶niczych oraz ma wp艂yw na rozw贸j p艂odu.
Opublikowane w 2007 roku wytyczne Towarzystwa Endokrynologicznego (Endocrine Society), opracowane przy wsp贸艂udziale Towarzystwa
Tyreologicznego Ameryki 艁aci艅skiej (LATS), Towarzystwa Tyreologicznego Azji i Oceanii (AOTA), Ameryka艅skiego Towarzystwa
Tyreologicznego (ATA) oraz Europejskiego Towarzystwa Tyreologicznego (ETA), w du偶ym stopniu usystematyzowa艂y zasady post臋powania
w chorobach tarczycy w czasie ci膮偶y i w okresie poporodowym. Pomimo ogromnego post臋pu wiedzy na temat wzajemnego wp艂ywu
ci膮偶y i funkcji gruczo艂u tarczowego w zdrowiu i chorobie, jaki osi膮gni臋to w ci膮gu ostatnich kilkunastu lat, nadal pewne obszary wymagaj膮
dalszych bada艅. W ci膮gu 3 lat, kt贸re min臋艂y od publikacji wytycznych, przyby艂o danych, kt贸re wp艂yn臋艂y na niekt贸re zasady prowadzenia
ci臋偶arnej z chorob膮 tarczycy. Wytyczne nie zawsze maj膮 charakter uniwersalny i nie mog膮 by膰 w prosty spos贸b transponowane na spo艂ecze艅stwa
zr贸偶nicowane etnicznie i ekonomicznie, o odmiennych zwyczajach dietetycznych, w tym w spo偶yciu no艣nik贸w jodu, oraz
stosuj膮ce odmienne modele profilaktyki jodowej.
W 2008 roku powo艂ano Zesp贸艂 Ekspert贸w do spraw Opieki Tyreologicznej w Ci膮偶y. Za cele prac Zespo艂u przyj臋to: opracowanie modelu
opieki nad ci臋偶arn膮 z zaburzeniami funkcji tarczycy, okre艣lenie grupy kobiet z ryzykiem zaburze艅 funkcji tarczycy wymagaj膮cych oceny
tyreologicznej podczas planowania ci膮偶y, w trakcie jej trwania oraz w okresie poporodowym — czyli przygotowanie polskich wskaza艅
do bada艅 przesiewowych oraz ustalenie warto艣ci referencyjnych st臋偶e艅 hormon贸w tarczycy w poszczeg贸lnych trymestrach ci膮偶y.
Opracowane przez Zesp贸艂 wytyczne systematyzuj膮 zasady opieki tyreologicznej nad kobiet膮 ci臋偶arn膮 w Polsce.
