ABSTRACT
Objetivo El cáncer papilar de tiroides (CPT) tiene diferentes variantes y la mayoría de ellas presentan diferencias sutiles. La variante oncocítica (VO) es un subtipo poco frecuente de CPT, sobre el pronóstico de la cual existen resultados controvertidos en la literatura. Investigamos su agresividad y curso clínico comparándolos con la variante clásica (VC) y la variante de células altas (CA) de CPT en diferentes estadios. Material y métodos En este estudio de cohortes retrospectivo se incluyeron: 100 muestras simples de VO, 71 de CA y 1.219 de VC. Las muestras VO se compararon con las VC y las de CA sobre la base de parámetros de pronóstico independientes. La recurrencia de la VO también se comparó estadio por estadio con la VC y CA. Resultados La edad media fue de 46,8 años y la relación hombres/mujeres de 25/75 para la VO. Las tasas de recurrencia en nuestro estudio fueron del 16% en VO; del 13,5% en VC y del 56% en CA. Existe una diferencia estadísticamente significativa con respecto a la recurrencia entre el estadio 1 y el estadio 4 comparando la VO y la VC (p=0,023; p=0,03, respectivamente). También hay una diferencia estadísticamente significativa con respecto a la recurrencia entre el estadio 1 y el estadio 4 comparando la VO y la CA (p=0,001; p=0,024, respectivamente). Se puede suponer que la VO tiene un comportamiento entre la VC y la CA, pero muy cercana a la CA. Conclusión La VO parece ser un poco más agresiva que la VC. A pesar de un tamaño de muestra inadecuado para los estadios 2 y 3, nuestros hallazgos implican un mayor riesgo de recurrencia para la VO que para la VC en los estadios avanzados (estadios 3 y 4) y la VC tiene un pronóstico más desfavorable que VO en estadios precoces (estadios 1 y 2), según el modelo de estadio pareado (AU)
Objective Papillary thyroid cancer (PTC) has many variants and most of them are mild tumors. Oncocytic variant (OV) is a rare subtype of PTC. There are controversial results about its prognosis in the literature. We investigated its aggressivity and clinical course by comparing it with classical variant (CV) and tall cell variant (TV) of PTC over a stage-matched design. Material and methods Pure 100 OV, 71 TV and 1,219 CV were included in this retrospective cohort study. OV was compared with CV and TV according to independent prognostic parameters. OV was also compared stage by stage with CV and TV for recurrence. Results Mean age was 46,8 years and male/female ratio 25/75 for OV. The recurrence rates in our study were 16% in OV, 13,5% in CV and 56% in TV. There is a statistically significant difference according to recurrence between stage 1 and stage 4 OV and CV (P = 0.023, P = 0.03, respectively). There is also a statistically significant difference between stage 1 and stage 4 OV and TV according to recurrence (P = 0.001, P = 0.024, respectively). OV can be supposed to behave between CV and TV, but very closer to CV. Conclusions OV seems to be slightly more aggressive than CV. Despite an inadequate sample size for stage 2 and 3, our findings imply an increased recurrence risk for OV than CV at the advanced stages (stage 3 and 4) and CV has an unfavorable prognosis than OV at early stages (stage 1 and 2) according to stage-matched model (AU)

There is a statistically significant difference according to recurrence between stage I and stage IV OV and CV (p=0.023, p=0.03, respectively).

OV can be supposed to behave between CV and TV, but very closer to CV. CONCLUSIONS: OV seems to be slightly more aggressive than CV. Despite an inadequate sample size for stage II and III, our findings imply an increased recurrence risk for OV than CV at the advanced stages (stage III and IV) and CV has an unfavorable prognosis than OV at early stages (stage I and II) according to stage-matched model.

This study was performed to evaluate whether the use of drugs in the treatment of osteoporosis in women is associated with COVID-19 outcomes. The results showed that the risk of hospitalization, intensive care unit admission, and mortality was not altered in individuals taking anti-osteoporosis drugs, suggesting no safety issues during a COVID-19 infection. INTRODUCTION: Whether patients with COVID-19 receiving anti-osteoporosis drugs have lower risk of worse outcomes has not been reported yet. The aim of this study was to evaluate the association of anti-osteoporosis drug use with COVID-19 outcomes in women. METHODS: Data obtained from a nationwide, multicenter, retrospective cohort of patients diagnosed with COVID-19 from March 11th to May 30th, 2020 was retrieved from the Turkish Ministry of Health Database. Women 50 years or older with confirmed COVID-19 who were receiving anti-osteoporosis drugs were compared with a 1:1 propensity score-matched COVID-19 positive women who were not receiving these drugs. The primary outcomes were hospitalization, ICU (intensive care unit) admission, and mortality. RESULTS: A total of 1997 women on anti-osteoporosis drugs and 1997 control patients were analyzed. In the treatment group, 1787 (89.5%) women were receiving bisphosphonates, 197 (9.9%) denosumab, and 17 (0.9%) teriparatide for the last 12 months. Hospitalization and mortality rates were similar between the treatment and control groups. ICU admission rate was lower in the treatment group (23.0% vs 27.0%, p = 0.013). However, multivariate analysis showed that anti-osteoporosis drug use was not an independent associate of any outcome. Hospitalization, ICU admission, and mortality rates were similar among bisphosphonate, denosumab, or teriparatide users. CONCLUSION: Results of this nationwide study showed that preexisting use of anti-osteoporosis drugs in women did not alter the COVID-19-related risk of hospitalization, ICU admission, and mortality. These results do not suggest discontinuation of these drugs during a COVID-19 infection.

Vertebral Eosinophilic Granuloma (EG) is a frequently reported disease, but further dissemination rarely occurs when the initial lesion is in the lumbar region. We present a case of EG, initially located in L5 vertebra, which disseminated to the skeletal bones and pulmonary system months after total excision in an adult.

A case of isolated brucella disk infection mimicking fragmented disk herniation is presented. MRI studies were performed two times in 6 months, both of which did not show any signs of spondylitis. Since brucella infections are seen along with spondylitis, this case has attracted our attention. We focused on radiological findings in this pure brucella disk infection.
