Evaluation of albendazole efficiency and complications in patients with pulmonary hydatid cyst

 Open in a separate windowOBJECTIVESThis study investigated the efficacy and complications of albendazole use after surgery in patients with pulmonary hydatid cysts.METHODSOne hundred fifty-three consecutive patients who met the study criteria out of 215 patients who received prophylaxis with albendazole after surgery for isolated pulmonary hydatid cysts in our clinic between January 2011 and December 2020 were analysed retrospectively.RESULTSEighty-six out of 153 (56.2%) of cases were male and 67 (43.8%) were female. The average age was 24.6 ± 17.4 (between 3 and 71 years), 76 of them (49.7%) were 18 years old and younger, while 77 (50.3%) were adults. All cases were approached transthoracically and a total of 170 operations were performed on the 153 cases. Fever, weakness and dizziness were reported in only one patient who was given albendazole treatment. A partial increase in liver enzymes was observed in 16 cases (10.5%) after albendazole treatment. Mild leukopoenia and neutropenia were observed in only one of the cases. In 1 case, a second operation was performed 30 months later due to recurrence. Albendazole treatment was not required to be discontinued in any of the cases. Mortality was not observed in any of the cases. Factors such as mean age, cyst size and hospitalization period did not have a statistically significant effect on any changes in liver enzymes tests following albendazole therapy (P > 0.05).CONCLUSIONSAlbendazole treatment can safely be used for postoperative prophylaxis in patients with pulmonary hydatid cysts in a controlled manner without causing serious complications.Subj collection152.     

Inpatient rehabilitation outcomes in neoplastic spinal cord compression vs. traumatic spinal cord injury

Objective: To compare neurological and functional outcomes, and complications of patients with neoplastic vs traumatic spinal cord injury (SCI) after in-patient rehabilitation.Design: This study is a retrospective analysis.Setting: In-patient rehabilitation unit of a tertiary research hospital.Participants: A total of 252 patients with a SCI were included; 43 with neoplastic SCI (mean age: 60.9 ± 15.7 years, 60.5% were males) and 209 with traumatic SCI (mean age: 43.1 ± 16.8 years, 71.3% were males).Outcome measures: Comparisons were made of demographic characteristics, etiology, American Spinal Injury Association (ASIA) impairment scale, functional independence measurement (FIM) and Functional Ambulation Categories (FAC) scores, length of stay (LOS), bladder independence, medical comorbidities and complications in both groups.Results: Patients with neoplastic SCI were significantly older than those with traumatic SCI (P < 0.01). No difference was present between the groups in terms of sex and lesion level (P > 0.05). Incomplete SCI was significantly higher in the neoplastic group when compared with the traumatic group (P < 0.01). The LOS was significantly shorter in the neoplastic group than traumatic group (34.8 ± 41.03 vs. 60.02 ± 53.1, P < 0.01). There were no differences in the admission FIM scores (69.3 ± 24.7 vs. 58.7 ± 18.9, P > 0.05), discharge FIM scores (82.1 ± 25.1 vs. 74.02 ± 23.3, P > 0.05) and FIM efficiencies (0.43 ± 0.72 vs. 0.36 ± 0.51, P > 0.05) for the neoplastic and traumatic groups, respectively. However, neoplastic SCI patients demonstrated lower FIM gains compared to traumatic patients (12.9 ± 11.9 vs. 15.4 ± 15.2, P < 0.05). During rehabilitation, urinary tract infection (48.4% vs. 69.4%) and decubitus ulcer (11.6% vs. 35.9%) were significantly more common in the traumatic group than the neoplastic group (P < 0.05).Conclusion: Neoplastic SCI patients who commonly present at rehabilitation units exhibit different characteristics from traumatic SCI patients but the rehabilitation results are similar. Similar functional development can be achieved in a shorter period of time with inpatient rehabilitation in the neoplastic SCI group.     

Loss of DPP4 activity is related to a prothrombogenic status of endothelial cells: implications for the coronary microvasculature of myocardial infarction patients

Pro-coagulant and pro-inflammatory intramyocardial (micro)vasculature plays an important role in acute myocardial infarction (AMI). Currently, inhibition of serine protease dipeptidyl peptidase 4 (DPP4) receives a lot of interest as an anti-hyperglycemic therapy in type 2 diabetes patients. However, DPP4 also possesses anti-thrombotic properties and may behave as an immobilized anti-coagulant on endothelial cells. Here, we studied the expression and activity of endothelial DPP4 in human myocardial infarction in relation to a prothrombogenic endothelial phenotype. Using (immuno)histochemistry, DPP4 expression and activity were found on the endothelium of intramyocardial blood vessels in autopsied control hearts (n?=?9). Within the infarction area of AMI patients (n?=?73), this DPP4 expression and activity were significantly decreased, coinciding with an increase in Tissue Factor expression. In primary human umbilical vein endothelial cells (HUVECs), Western blot analysis and digital imaging fluorescence microscopy revealed that DPP4 expression was strongly decreased after metabolic inhibition, also coinciding with Tissue Factor upregulation. Interestingly, inhibition of DPP4 activity with diprotin A also enhanced the amount of Tissue Factor encountered and induced the adherence of platelets under flow conditions. Ischemia induces loss of coronary microvascular endothelial DPP4 expression and increased Tissue Factor expression in AMI as well as in vitro in HUVECs. Our data suggest that the loss of DPP4 activity affects the anti-thrombogenic nature of the endothelium.     

The beneficial effects of 18β-glycyrrhetinic acid following oxidative and neuronal damage in brain tissue caused by global cerebral ischemia/reperfusion in a C57BL/J6 mouse model

This study investigated the effects of 18β-glycyrrhetinic acid (GA) on neuronal damage in brain tissue caused by global cerebral ischemia/reperfusion (I/R) in C57BL/J6 mice. All subjects (n = 40) were equally divided into four groups: (1) sham-operated (SH), (2) I/R, (3) GA, and (4) GA+I/R. The SH group was used as a control. In the I/R group, the bilateral carotid arteries were clipped for 15 min, and the mice were treated with the vehicle for 10 days. In the GA group, mice were given GA (100 mg/kg) for 10 days following a median incision without carotid occlusion. In the GA+I/R group, the I/R model was applied to the mice exactly as in the I/R group, and they were then treated with the same dose of GA for 10 days. Cerebral I/R significantly induced oxidative stress via an increase in lipid peroxidaitons and a decrease in elements of the antioxidant defense systems. However, GA treatment was protective against the oxidative effects of I/R by inducing significant increases in antioxidant defense systems and a significant decrease of lipid peroxidations. Additionally, cerebral I/R increased the incidence of histopathological damage and apoptosis in brain tissue, but these neurodegenerative effects were eliminated by GA treatment. Therefore, the current study demonstrated that GA treatment effectively prevents oxidative and histological damage in the brain caused by global I/R. In this context, GA may be useful for the attenuation of the negative effects of global cerebral I/R and, in the future, it may be a viable and safe alternative treatment for ischemic stroke in humans.     

A comparison of suprascapular nerve block and procedural sedation analgesia in shoulder dislocation reduction

Objectives

Dislocation of the shoulder joint is one of the most common dislocations. The reduction procedure is a painful procedure. In this study, 2 different treatment groups were compared for pain control during shoulder dislocation reduction. It was aimed to evaluate the differences between the groups in reduction, success, length of hospital stay, complications, side effects, patient-physician satisfaction, and ease of application.

Methods

The study was planned to be prospective and randomized. As procedural sedation analgesia (SA), titration of ketamine 1 to 2 mg/kg was administered intravenously to group 1. Suprascapular nerve block (SNB) was applied under ultrasound guidance (USG) to group 2. Conformity to normal distribution of variables was examined with the Kolmogorov-Smirnov test. The χ² test and Fisher test were used to evaluate differences between the groups in categorical variables and the Mann-Whitney U test, and a value of P < .05 was accepted as statistically significant.

Results

The study comprised a total of 41 patients; 20 in the group 1 and 21 in the group 2. No statistically significant difference was determined between the groups in terms of age (P = .916), sex (P = .972), reduction success (P = .540), and patient-physician satisfaction (P = .198). The time spent in the emergency department (ED) by patients in the SA group was signficantly longer compared with the SNB group. No side effects were observed in the SNB group.

Conclusions

Suprascapular nerve block, which can be easily applied under USG in the ED, can be evaluated as a good alternative to SA in the reduction of shoulder dislocations.     

A case of rhabdomyolysis associated with thyrotoxicosis

Rhabdomyolysis is found to be associated with trauma; alcohol; drugs; viral infections, such as HIV, Epstein-Barr virus, cytomegalovirus and influenza; metabolic disorders; dermatomyositis; polymyositis; and hypothyroidism. Few cases of rhabdomyolysis associated with thyrotoxicosis have been reported. A patient who presented with delirium to the emergency department and was diagnosed with thyrotoxicosis and rhabdomyolysis is hereby presented.     

Trabecular Shear Stresses Predict <Emphasis Type="Italic">In Vivo</Emphasis> Linear Microcrack Density but not Diffuse Damage in Human Vertebral Cancellous Bone

Linear microcracks and diffuse damage (staining over a broad region) are two types of microscopic damage known to occur in vivo in human vertebral trabecular bone. These damage types might be associated with vertebral failure. Using microcomputed tomography and finite element analysis for specimens of cancellous bone, we estimated the stresses in the trabeculae of human vertebral tissue for inferosuperior loading. Microdamage was quantified histologically. The density of in vivo linear microcracks was, but the diffuse damage area was not, related to the estimates of von Mises stress distribution in the tissue. In vivo linear microcrack density increased with increasing coefficient of variation of the trabecular von Mises stress and with increasing average trabecular von Mises stress generated per superoinferior apparent axial stress. Nonlinear increase in linear crack density, similar to the increase of the coefficient of variation of trabecular shear stresses, with decreasing bone stiffness and bone volume fraction suggests that damage may accumulate rather rapidly in diseases associated with low bone density due to the dramatic increase of shear stresses in the tissue. © 2003 Biomedical Engineering Society.
