Solution phase high repetition rate laser pump x-ray probe picosecond hard x-ray spectroscopy at the Stanford Synchrotron Radiation Lightsource.

We present a dedicated end-station for solution phase high repetition rate (MHz) picosecond hard x-ray spectroscopy at beamline 15-2 of the Stanford Synchrotron Radiation Lightsource. A high-power ultrafast ytterbium-doped fiber laser is used to photoexcite the samples at a repetition rate of 640 kHz, while the data acquisition operates at the 1.28 MHz repetition rate of the storage ring recording data in an alternating on-off mode.

Sternotomy in thyroid surgery.

Introduction: A bulky retrosternal goiter means for the surgeon to consider an extracervical approach, usually from a partial sternotomy. Methods: Retrospective evaluation of a group of thyroid operations requiring sternotomy in a ten-year period (year 2012–2021), in an attempt to predict the need for sternotomy. Results: We performed a total of 1254 thyroid operations, with partial sternotomy required in 11 cases (0.

[Descending Necrotising Mediastinitis: the Choice of Drainage].

Introduction: Descending necrotising mediastinitis (DNM) is a rare, but very severe, septic condition, caused by the spread of infection from the neck to the mediastinum. Delay in diagnosis and inadequate surgical procedures may lead to a life-threatening situation.

Material: We retrospectively evaluated a group of patients who suffered from DNM and were treated in our department by mediastinal drainage in the last 10 years (2010 - 2019).

Differentiated thyroid microcarcinoma current perspective.

Introduction: Differentiated thyroid cancer (DTC) has a good prognosis and low mortality despite its growing incidence, which is particularly the case of microcarcinomas (T1a - up to 10 mm).

Methods: Retrospective analysis of overall survival of patients in the group of thyroid gland surgeries for differentiated forms of microcarcinoma in the period of 2006-2015 up to the present. An overview of contemporary therapeutic methods is included.

Morgagni hernia - case reports.

Morgagni hernia is a rare form of diaphragmatic hernia. It is a congenital defect of the diaphragm, often asymptomatic in adulthood and thus usually found only incidentally. Its treatment is predominantly surgical.
