Abstract Background We report a case of isolated metastasis on the anterior clinoid process (ACP) mimicking meningioma. Clinical Presentation A 58-year-old male presented with headaches, right-sided visual disturbances, and blurred and double vision. The cause of double vision was partial weakness of the right III nerve, resulting from compression of the nerve by “hypertrophied” tumor-involved right anterior clinoid. Medical history revealed two primary malignant tumors—male breast cancer and prostate cancer (diagnosed 6 and 18 months prior, respectively). The patient was treated with chemotherapy and showed no signs of active disease, recurrence, or metastasis. Postcontrast head magnetic resonance imaging (MRI) showed extra-axial well-bordered enhancing mass measuring 1.6 × 1.1 × 1 × 1 cm (anteroposterior, transverse, and craniocaudal dimensions) on the ACP, resembling a clinoidal meningioma. Extradural clinoidectomy with tumor resection was performed via right orbitozygomatic pretemporal skull base approach. Visual symptoms improved. Follow-up MRI showed no signs of tumor residual or recurrence. Conclusion This is the first case report of a metastasis of any kind on ACP. Metastasis should be included as a part of the differential diagnosis of lesions of the anterior clinoid. Extradural clinoidectomy is a safe and effective method in the treatment of these tumors.

Background: There is insufficient knowledge regarding the influence of concomitant injuries on the recovery of short-term subjective knee function after anterior cruciate ligament (ACL) reconstruction. Purpose: To determine whether patient characteristics, concomitant injuries, and graft choice during ACL reconstruction can predict which patients achieve acceptable knee function 1 year after reconstruction. Study Design: Case-control study; Level of evidence, 3. Methods: Data from 1 physical therapist–specific and 1 surgeon-specific register were used. Patients who had completed the Knee injury and Osteoarthritis Outcome Score (KOOS) at 1-year follow-up were included. Additional intraoperative information was extracted from a database. The primary outcome was achieving a patient-acceptable symptom state (PASS) for each subscale of the KOOS. Univariable and multivariable logistic regression models were used, with patient sex, age, and preinjury level of physical activity as covariates. Results: A total of 343 patients (51% females) were included. The proportion of patients achieving PASS 1 year after ACL reconstruction varied between 40% and 85% among the KOOS subscales. Younger age at reconstruction and male sex provided favorable odds of achieving acceptable knee function across the KOOS subscales. Patients without cartilage injury had increased odds of achieving PASS in the KOOS sport and recreation subscale; the increase was 1.63-fold (95% CI, 1.01-2.64; P = .045). Patients receiving patellar tendon autograft had a 0.41-fold (95% CI, 0.19-0.85; P = .017) decrease in odds of achieving PASS on the KOOS quality of life (QoL) subscale. In the multivariable analysis, increased odds of achieving PASS on the KOOS QoL subscale were associated with the absence of meniscal injury (odds ratio, 1.62; 95% CI, 1.04-2.54; P = .035), and increased odds were found for hamstring tendon autograft (OR, 2.63; 95% CI, 1.25-5.56; P = .011). Conclusion: More than half of the patients reported an acceptable symptom state on 4 of the 5 KOOS subscales 1 year after ACL reconstruction. A lack of consistency was noted related to the effect of concomitant knee injuries and graft choice on acceptable knee function. However, younger age and male sex were favorable, nonmodifiable characteristics that increased the odds of early acceptable function.

Background The purpose of this study is to establish whether the lymph node metastases of the papillary thyroid carcinoma are a significant factor in recurrence of the disease by analyzing the time until recurrence of the disease and frequency of recurrence of the disease. Methods From 1 January 1995 until 30 June 2017, 102 patients were treated at the Public Health Institute Hospital “Sveti Vracevi” in Bijeljina for PTC. In all patients, surgery of the thyroid gland and/or lymph nodes of the neck was performed. Total thyroidectomy (TT) was performed in 20 patients and near-total thyroidectomy leaving <1 g thyroid tissue adjacent to the recurrent laryngeal nerve in 7 patients. TT and lymph nodes dissection were performed in 71 patients. Palliative surgery and biopsy due to locally advanced disease were performed in 3 patients. Results In our study, 102 patients with PTC were analyzed. 82 patients experienced pure PTC (80.4%), the other 20 patients (19.6%) experienced other variants of PTC. 24 patients (23.5%) experienced multi centric or bilateral tumors. 71 patients (69.6%) experienced histologically verified metastases in the lymph nodes of the neck. 7 patients (6.8%) experienced distant metastases. 20 patients underwent total thyroidectomy (TT), and 7 near-total thyroidectomy. Total thyroidectomy + dissection of central and lower jugular lymph nodes with frozen section histopathology verification was performed in 71 patients (69.6%). Out of these 71 patients, in 50 patients (70.4%) metastases were verified in the lower jugular lymph nodes. A modified lymph node dissection (MRND) was also performed in these patients. Conclusion Lymph node metastases of the papillary thyroid carcinoma are a plausible prognostic factor. They are important for recurrence of the disease, but not for survival.

Introduction Duplicated ureter or Duplex Collecting System is a congenital condition in which the ureteric bud, the embryological origin of the ureter, arises twice, resulting in two ureters draining a single kidney. This congenital anomaly is rare, and even rarer when the duplex system with ectopic ureter is present. This type of congenital anomaly is even more rarely diagnosed and surgically treated in adulthood. Case report This case report presents a case of a 32-year-old male, who had a duplex collecting system with two ureters on the left side. Ectopic ureter, draining the upper pole of the left kidney, opened into the posterior urethra. In our patient, taking into account the clinical perspective, the renal tissue damaging of the upper pole which was not functional, partial nephrectomy and ureterectomy was successfully performed.

It is known that oxidoreductase is responsible for the regulation of oxidative stress in organisms, and pathological changes occur within the cell in the form of accumulation or lack of superoxide and peroxide radicals if the oxidoreductase activity is disturbed. Currently, the development of drugs that target the affected cells while leaving healthy cells unaffected is of great interest. The action of potential drugs is based on the inhibition / activation of oxidoreductase. In this work, we studied the electrochemical parameters of superoxide dismutase as well as the action of the potential drug of boroxine - dipotassium trioxohydroxytetrafluorotriborate (K2[B3O3F4OH]) as a target therapeutic for enzyme activity. Electrochemical tests were carried out in a classical three-electrode system using cyclic voltammetry and chronoamperometry techniques, and the obtained results were presented in the form of the kinetic parameters with the maximum value of the current obtained when the solution was saturated with the substrate (Imax) and the Michaelis-Menten constant (Km). K2[B3O3F4OH] was proven to be a reversible inhibitor, and the obtained Imax without inhibitor value of 0.014 mM and Km = 12.09 mM. The results from the Lineweaver - Burk diagram show that the inhibition is a partial noncompetitive inhibition type.

Summary Background: There is still no reliable, specific biomarker for precision diagnosis and clinical monitoring of systemic lupus erythematosus. The aim of this study was to investigate the importance of the determination of immunofenotypic profiles (T, B lymphocytes and NK cells) and serum cytokine concentrations (IL-17 and IFN-alpha) as potential biomarkers for this disease. Methods: The study included 55 patients with SLE and 25 healthy controls. The proportion of T, B, NK cells were assessed in peripheral blood using flow cytometric assays while the serum cytokine concentration (IL-17 and IFNalpha) was determined by ELISA test. Results: ROC curve analysis showed good accuracy to distinguish between patients and healthy individuals for activated T cells (AUC=0.798; p<0.001), Treg (AUC= 0.651; p=0.036), and memory B cells (AUC=0.285; p=0.002). We found statistically significant difference (p=0.036) in the levels of serum IL-17 between patients with SLE (IL-17=49.27 pg/mL) and controls (IL-17= 28.64 pg/mL). Conclusions: Significant increase in the relative number of Treg lymphocytes, and decrease in memory B cells, as well as decrease level of IL-17, in SLE patients may be implicated in the pathogenesis of the disease. These parameters, as biomarkers, could distinguish SLE patients and no-SLE patients. Monitoring subpopulations of immune cells in peripheral blood using flow cytometry provides insight into abnormal T and B cell function in SLE. Progress in understanding the immunity at SLE, results in concrete benefits for the SLE patients, which include new clinical management and therapeutic strategies.

Cardiovascular diseases (CVDs) are the major cause of disability and premature death all over the world. Annually, 17.5 million people die from CVDs, representing 30% of the total number of deaths. Despite established guidelines for the treatment of acute coronary syndrome, cardiac weakness, atrial fibrillation and CVD prevention, many patients remain inadequately treated, particularly in less developed nations. A brief overview of the development of CVDs, description of the current practice guidelines, and a cross sectional analyses of the status of CVD prevention and control in the Federation of Bosnia and Herzegovina is given. In the past 7 years, there has been a steady increase in deaths, where half of all deaths in the Federation of Bosnia and Herzegovina are attributed to CVDs. Deaths from the acute myocardial infarction had a rate of 91.0/100,000 inhabitants, a significant increase compared to 2010, when this rate was 69.2. The second leading cause of death, a stroke, with a rate of 87.1 showed a slight decrease compared to 2010, when it was 89.9. The third leading cause of death, heart failure, with a rate of 68.4, has a slight decrease compared to 2010, when the rate was 75.7. CVDs are the leading cause of mortality in Federation of Bosnia and Herzegovina, which, in addition to the large number of premature deaths, also causes major costs for the health sector and economy.
