Lumbar spinal stenosis: methods of treatment with emphasis on epidural steroid injections

Background and Purpose: The aim of the study was to compare two techniques of steroid application into epidural space to patients with lumbar spinal stenosis (LSS), a chronic degenerative spine disorder. Patients and Methods: Sixty LSS patients have been distributed into 2 groups: “BLIND” (n=30, interlaminar epidural steroid injection without RTG control) and “RTG” (n=30, transforaminal epidural injection with RTG control). All patients have received 80 mg of triamcinolon (Kenalog) into epidural space on L4/L5 level, together with 0,5% lidocain (patients in RTG group 3 ml and those in BLIND group 10 ml) in 3 week intervals. They were asked to describe the pain using visual analogue scales (VAS) at the beginning of treatment (VAS-0), after the first (VAS-1), the second (VAS-2) and the third epidural injection (VAS-3). The differences between groups were shown using t-test (age) and c2-test (gender). Medians of VAS scores were statistically described using non parametrial methods. P<0.05 was considered as a statistically significant. Results: There is no statistical difference among patients regarding to age (P=0.93), gender (P=0.12) and VAS-0 score before the first injection (P=0.27). There is a statistically significant reduction of pain in relation to VAS-0 in both groups (P<0.001). Both groups do not statistically differ when it comes to their effectiveness in regards to VAS scores. Conclusions: We did not find any statistical difference in postinterventional VAS scores among two groups of patients. Choice of technique depends on the experience of the anesthesiologist, as well as on the local technical possibilities (availibility of RTG devices)

Laboratory medicine in pandemic of COVID-19

After the outbreak in China in the year 2019, severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) quickly spread around the world causing a protracted pandemic. Approximately one-third of infections appear to be asymptomatic. Symptomatic disease is characterized primarily by symptoms of respiratory tract infection of varying severity. But Coronavirus Disease 2019 (COVID-19) is much more than an acute respiratory disease because SARS-CoV-2 affects many organs inducing a vast number of symptoms such as cardiovascular, neurological, gastrointestinal, dermatological, with numerous complications. Short and long-term effects of infection, severe ones, and especially mild forms of the disease which affect a huge number of patients need to be further investigated. Laboratory medicine has a crucial role in early diagnosis of the disease, recognition of the patients who need hospital care, and close monitoring of hospitalized patients to timely identify associated clinical complications as well as follow-up of patients with long-term COVID-19

Intravenous anaesthesia for adenoidectomy in a 3-year-old child with Kartagener syndrome and sleep disordered breathing

Kartagener syndrome (KGS) is a rare inherited disorder characterized by situs inversus viscerum (including dextrocardia) and primary ciliary dyskinesia resulting in chronic respiratory tract infections, bronchiectasis and sinusitis. Possible anesthesiologic challenges are related to the respiratory system and increased susceptibility to infectious complications. There are several case reports of general anesthesia in these patients, but mainly in the adult population . Here, we report on a 3-year old female child with KGS, who underwent adenoidectomy because of sleep disordered breathing (SDB). Preoperative preparation consisted of intravenous antibiotics, steroids, as well as postural drainage and inhalations of bromhexine and salbutamol. Anesthesia was induced with propofol, fentanyl and vecuronium and maintained with a continuous infusion of propofol (150-200 gkg-1min-1) and supplemental doses of fentanyl. The child was ventilated with oxygen/air mixture (50%:50%) in the pressure-controlled mode of ventilation to keep end-tidal CO2 between 30 and 35 mmHg. During anesthesia the child’s hemodynamic and respiratory parameters were stable. Extubation, after thorough endotracheal and oral suction, was uneventful. After two hours in the post-anaesthesia care unit (PACU), the child was transferred to the ward. To the best of our knowledge, this is the youngest reported child with KGS and SDB that underwent intravenous general anesthesia. We also stress here the importance of comprehensive pre-anesthetic preparation, i.e. postural drainage, inhalations, bronchodilators, i.v. antibiotics and steroids. Furthermore, the condition of the respiratory system in the patient with KGS is seldom appropriate at the time of surgery, so the decision to anesthetize or not, should be made on an individual basis

Dynamic of Serum TWEAK Levels in Critically Ill COVID-19 Male Patients

Although the number of cases and mortality of COVID-19 are seemingly declining, clinicians endeavor to establish indicators and predictors of such responses in order to optimize treatment regimens for future outbreaks of SARS-CoV-2 or similar viruses. Considering the importance of aberrant immune response in severe COVID-19, in the present study, we aimed to explore the dynamic of serum TNF-like weak inducer of apoptosis (TWEAK) levels in critically-ill COVID-19 patients and establish whether these levels may predict in-hospital mortality and if TWEAK is associated with impairment of testosterone levels observed in this population. The present single-center cohort study involved 66 men between the ages of 18 and 65 who were suffering from a severe type of COVID-19. Serum TWEAK was rising during the first week after admission to intensive care unit (ICU), whereas decline to baseline values was observed in the second week post-ICU admission (p = 0.032) but not in patients who died in hospital. Receiver-operator characteristics analysis demonstrated that serum TWEAK at admission to ICU is a significant predictor of in-hospital mortality (AUC = 0.689, p = 0.019). Finally, a negative correlation was found between serum TWEAK at admission and testosterone levels (r = −0.310, p = 0.036). In summary, serum TWEAK predicts in-hospital mortality in severe COVID-19. In addition, inflammatory pathways including TWEAK seem to be implicated in pathophysiology of reproductive hormone axis disturbance in severe form of COVID-19

Association between Brain Injury Markers and Testosterone in Critically-Ill COVID-19 Male Patients

Accumulating data suggest that various neurologic manifestations are reported in critically-ill COVID-19 patients. Although low testosterone levels were associated with poor outcomes, the relationship between testosterone levels and indices of brain injury are still poorly understood. Therefore, we aimed to explore whether testosterone levels are associated with glial fibrillary acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase L1 (UCH-L1), biomarkers of brain injury, in patients with a severe form of COVID-19. The present study was conducted on 65 male patients aged 18&ndash;65 with severe COVID-19. Blood samples were collected at three time points: upon admission to ICU, 7 days after, and 14 days after. In patients with neurological sequels (n = 20), UCH-L1 serum concentrations at admission were markedly higher than in patients without them (240.0 (155.4&ndash;366.4) vs. 146.4 (92.5&ndash;243.9) pg/mL, p = 0.022). GFAP concentrations on admission did not differ between the groups (32.2 (24.2&ndash;40.1) vs. 29.8 (21.8&ndash;39.4) pg/mL, p = 0.372). Unlike GFAP, UCH-L1 serum concentrations exhibited a negative correlation with serum testosterone in all three time points (r = &minus;0.452, p &lt; 0.001; r = &minus;0.430, p &lt; 0.001 and r = &minus;0.476, p = 0.001, respectively). The present study suggests that the traumatic brain injury biomarker UCH-L1 may be associated with neurological impairments seen in severe COVID-19. Moreover, a negative correlation between UCH-L1 and serum testosterone concentrations implies that testosterone may have a role in the development of neurological sequels in critically-ill COVID-19 patients
