The impact of misplaced percutaneous iliac dynamic reference frame pins used during navigated spine surgery: incidence and outcomes
Authors: Holste Katherine G. , Zaki Mark M. , Wieland Clare M. , Saadeh Yamaan S. , Park Paul 
Published: March 2022

OBJECTIVE
Image guidance requires placement of a dynamic reference frame (DRF), often either onto local spinous process or by freehand intraosseous DRF placement into the ilium via the posterior superior iliac spine (PSIS). There is a paucity of studies in the literature that describe the complications of intraosseous DRF placement. The aim of this study was to describe the radiographic location, prevalence and nature of complications, and long-term clinical outcomes of attempted DRF placement into the PSIS.

METHODS
All lumbosacral spine surgical procedures performed between August 2019 and February 2021 at a single institution were queried, and operations in which a DRF was targeted to the PSIS were included. Patient demographic characteristics, indications for surgery, surgical outcomes, and complications were extracted. Intraoperative CT scans were reviewed by 2 independent researchers to determine the accuracy of DRF placement into the PSIS and to assess for DRF malposition.

RESULTS
Of 497 lumbar spine operations performed between August 2019 and February 2021 by 4 surgeons, 85 utilized intraoperative navigation with a PSIS pin. Thirteen operations were excluded due to an inability to visualize the entirety of the pin on intraoperative CT. Of 72 DRFs evaluated, 77.8% had been correctly placed in the PSIS. Of the 22.2% of DRFs not placed into the PSIS, 11 entered the sacrum, 6 crossed the sacroiliac joint, and 2 were deep enough to enter the pelvis. Pain at the pin site was present in 4 patients, of whom 3 had resolution of pain at the last follow-up evaluation. There were no significant complications due to DRF placement: no sacral fractures, significant navigation errors, retroperitoneal hematomas, or neurological deficits. Over a mean ± SD follow-up period of 9 ± 5.2 months, there were no incidences of pin site infection. Interrater reliability between the reviewers was 95.8%.

CONCLUSIONS
This was the first study to examine radiological and clinical outcomes after DRF placement in the PSIS. In this study, a majority of pins were correctly placed within the PSIS, although 22.2% of pins were malpositioned. There were no serious complications, and a majority of those patients with persistent pin site pain had resolution at last follow-up.

OBJECTIVE
Real-time, MRI-guided laser interstitial thermal therapy (MRgLITT) has been reported as a safe and effective technique for the treatment of epileptogenic foci in children and adults. After the recent approval of MRgLITT by the European Medicines Agency in April 2018, the authors began to use it for the treatment of hypothalamic hamartomas (HHs) in pediatric patients with the assistance of a robotic arm. In this study, the authors report their initial experience describing the surgical technique, accuracy of the robotic arm, safety, and efficacy.

METHODS
The laser fiber was placed with the assistance of the stereotactic robotic arm. The accuracy of the robotic arm for this procedure was calculated by comparing the intraoperative MRI to the preoperative plan. Common demographic and seizure characteristics of the patients, laser ablation details, complications, and short-term seizure outcomes were prospectively collected.

RESULTS
Sixteen procedures (11 first ablations and 5 reablations) were performed in 11 patients between 15 months and 17 years of age (mean age 6.4 years) with drug-resistant epilepsy related to HHs. The mean target point localization error was 1.69 mm. No laser fiber needed to be repositioned. The mean laser power used per procedure was 4.29 W. The trajectory of the laser fiber was accidentally ablated in 2 patients, provoking transient hemiparesis in one of these patients. One patient experienced postoperative somnolence and syndrome of inappropriate antidiuretic hormone secretion, and 2 patients had transient oculomotor (cranial nerve III) palsy. Fifty-four percent of the patients were seizure free after the first ablation (mean follow-up 22 months, range 15–33 months). All 5 patients who experienced an epilepsy relapse underwent a second treatment, and 4 remain seizure free at least 5 months after reablation.

CONCLUSIONS
In the authors’ experience, the robotic arm was sufficiently accurate for laser fiber insertion, even in very young patients. MRgLITT appears to be an effective treatment for selected cases of HH. MRgLITT for HH is a minimally invasive procedure with appealing safety features, as it allows delivery of energy precisely under real-time MRI control. Nonetheless, complications may occur, especially in voluminous HHs. The amount of delivered energy and the catheter cooling system must be closely monitored during the procedure. A larger sample size and longer follow-up duration are needed to judge the efficacy and safety of MRgLITT for HH more rigorously. This initial experience was very promising.

Authors: Abo AlShiekh Samira , Tawfeeq Zinah Abdul-Rahman , Jabre Kamal 
Published: March 2022

Background: Breast cancer is considered a major health problem and the most common cancer among females in both developed and non-developed countries. Early diagnosis of breast cancer decreases morbidities and mortalities. This study attempts to explore the accuracy measures of a digital mammography unit in the diagnosis of breast cancer and compare the mammography results with the final histopathology results.
Methods: The study was designed as a cross-sectional prospective hospital base in which mammography examination was used for patients. Then, U/S was performed as a complementary study. All the mammography and U/S reports were reviewed and compared with the histopathology results. Six indicators were used to measure the accuracy of the mammography system using their formulas. SPSS program was used to examine the correlation between imaging results and histopathological findings and to draw the area under the receiver operating characteristic curve (AUC). Confidence interval was considered at 95% and margin of error at 5%.
Results: Sensitivity, Specificity, PPV, NPV, accuracy and the area under the ROC curve of mammography alone were 94.9%, 66.7%, 90%, 66.7%, 0.771 and increased to 100%, 76.9%, 90.3%, 100%, 92.7%, 0.917, respectively when Ultrasound was used as a complementary to mammography. A statistically significant moderate correlation was shown between the results of mammography alone and histopathology results (Spearman correlation= 0.527, P-value<0.01), and a statistically significant strong correlation between mammography combined with ultrasound, and histopathology results (Spearman correlation=0.882, P-value<0.01).
Conclusion: Mammography is an important tool to detect breast cancer. Mammography when combined with Ultrasound yields a very significant improvement in sensitivity and specificity for diagnosing different breast lesions.
Aktivismi ja itsekasvatus
Authors: Saari Antti , Varpanen Jan , Kallio Johanna 
Published: March 2022

Kuvaamme artikkelissa erään aktivistiryhmän toimintaa itsekasvatuksena. Ryhmän toiminta edustaa kaupungeissa kasvavaa neljättä sektoria. Ymmärrämme ’itsekasvatuksen’ filosofi Michel Foucault’n ajattelua hyödyntäen itsestä huolehtimisena, jossa ihminen muokkaa ja harjoittaa itseään uudenlaisten tietämisen ja olemisen muotojen tavoittamiseksi. Itsekasvatus ymmärretään samalla niin sanottuna prefiguratiivisena politiikkana, jossa aktivismin keinot eivät aina erotu sen tavoitteista. Tarkastelemamme aktivistiryhmän toiminnassa itsekasvatus saa piirteitä niin liberaalista hallinnasta kuin henkisyyden eri muodoista. Nostamme analyysissä esiin, kuinka aktivistiryhmä kietoo nämä keskenään jännitteiset teemat yhteen Massachusetts Institute of Technology (MIT) -yliopistossa kehitettyä U-teoriaa hyödyntämällä.

Saksalaissosiologi Niklas Luhmann toteaa, että yhteiskunnalla ei ole yhtä keskusta. Siitä voi tehdä havaintoja vasta, kun on valinnut oman käsitteellisen erottelujärjestelmän, eikä kellään havainnoijalla ole etuoikeutettua asemaa. Luhmann muistuttaa meitä asioiden monimutkaisuudesta ja siitä, että maailmaa ei voi hallita tukeutumalla suoraviivaisiin syy–seuraus-suhteisiin.

Seismic performance assessment of high-rise steel moment frame building with Reinforced Concrete (RC) core wall based on nonlinear time history analysis
Authors: Azodi Maryam , Banazadeh Mehdi , Mahmoudi Amir 
Published: March 2022

This paper focuses on seismic responses of a 30-story high-rise building with a dual lateral system of Reinforced Concrete (RC) core shear wall and steel moment frame. To assess the seismic performance of the building, a nonlinear finite element model is built by using the OpenSees software. This three-dimensional model is created by using the fiber-beams for members and multi-layer shell elements for RC core walls. The numerical simulation has been examined under the thirteen sets of strong ground motion records which are scaled with the design and maximum seismic levels, Design-Basis Earthquake (DBE) and Maximum Considered Earthquake (MCE) level hazards respectively. In consequence, the desirable performance of high-rise steel moment frame building with RC shear core consisting of coupling beams and rectangular shear walls is shown. The outcome of nonlinear time history analyses reports the acceptable seismic performance of tall buildings designed. Results showed that maximum inter-story drift is significantly lower than allowable drift. Also, the RC core wall absorbed almost two-third of the total shear forces from the base level to one-third of height. However, the shear values of the core wall were significantly reduced by increasing the height while the shear values of the steel moment frame stayed constant.

Background: Meteorological variables play a major role in the transmission of infectious diseases such as coronavirus disease 2019 (COVID-19). Objective: To analyze the correlation between climatic variables and COVID-19 deaths/cases. Methods: An exploratory-descriptive study based on secondary data on deaths, cases of COVID-19 and climatic variables from March 2020-May 2021 in Fortaleza, Brazil. Data from the COVID-19 surveillance system of the Ministry of Health were used. The climatic indicators were extracted from the National Institute of Meteorology. The variables under study were temperature (minimum, mean and maximum in °C), relative air humidity (%), total precipitation (mm) and total daily insolation (h). Pearson's correlation and the linear regression model were used for statistical analysis. Correlations were considered significant when P ≤ 0.05 and a 95% confidence interval was adopted. Results: All meteorologic variables were correlated with deaths from COVID-19, temperature minimum (r = -0,126; P < 0,01), mean temperature (r = -0,146; P < 0,05), maximum temperature (r = -0,190; P < 0,001), insolation (r = -0,214; P < 0,001), precipitation (r = 0,216; P < 0,001) and relative humidity (r = 0,348; P < 0,001). In relation to the new cases of COVID-19, only maximum temperature (r = -0,116; P < 0,05), insolation (r = -0,141; P < 0,01) and relative humidity (r = 0,231; P < 0,001) were correlated are significantly. Conclusion: There were significant correlations between meteorological variables and COVID-19 deaths/cases. It was found that meteorologic variables had the most influence on COVID-19 deaths.
