Histological Structure and Immunohistochemical Properties of the Ligamentum Teres in Patients With Developmental Dysplasia of the Hip.

Introduction This study aims to evaluate the histology of the ligamentum teres and its relationship with matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS), which are involved in the destruction of extracellular matrix proteins in patients with developmental dysplasia of the hip (DDH). Methodology The patients who underwent open reduction and pelvic osteotomy due to DDH were included in the study. Patient groups were formed according to Tönnis stages, positive family history, consanguineous marriage, age, and bilateral involvement. The histology and immunohistochemical properties (MMP-2, MMP-9, and ADAMTS-7) of ligamentum teres tissue obtained from the patients were evaluated according to these groups. Results Thirty-five patients (female 30, 85.7%; male 5, 14.3%) with DDH between the ages of 14 and 99 months were included in the study. Preoperative and postoperative Tönnis stages, positive family history, consanguineous marriage, age, and bilaterality did not cause a significant difference between histological parameters. A significant correlation was found between MMP-2, MMP-9, and ADAMTS-7 and all histological parameters. Conclusions The histological structure of ligamentum teres in patients with DDH shows moderate inflammation, fibrosis, neovascularization, hyalinization, and fatty infiltration regardless of age and radiological stage. ADAMTS-7, MMP-2, and MMP-9 correlate positively with the histological parameters of the ligamentum teres in patients with DDH.

Comparison of local massage, steroid injection, and extracorporeal shock wave therapy efficacy in the treatment of lateral epicondylitis.

OBJECTIVES: This study aimed to compare the clinical outcomes of patients with lateral epicondylitis (LE) treated with local massage, corticosteroid (CS) injection, and extracorporeal shock wave therapy (ESWT). PATIENTS AND METHODS: This randomized prospective study included 52 patients. Patients treated with local massage in Group 1 (n=17; 9 males, 8 females; mean age: 46.1±10.9 years; range, 27 to 64 years), CS injection in Group 2 (n=17; 7 males, 10 females; mean age: 46.0±8.8 years; range, 28 to 63 years), and ESWT in Group 3 (n=18; 12 males, 6 females; mean age: 46.7±11.3 years; range, 28 to 68 years) for LE were evaluated between March 2021 and June 2022. Clinical outcomes were assessed using the Visual Analog Scale (VAS), Disabilities of the Arm, Shoulder, and Hand (DASH), and DASH-Work Model (DASH-WM) scoring systems at the initial examination at the beginning of the study and at two-week, three-month, and six-month follow-up controls. RESULTS: Similar results were observed between VAS, DASH, and DASH-WM scores measured during LE diagnosis. In the first two weeks of follow-up, statistically significant decreases were observed in VAS, DASH, and DASH-WM scores in all three groups. Compared to baseline values, Group 1 and 2 had significant difference in VAS and DASH scores at three months. Group 3 had a significant difference in all clinical evaluation scores. At six months, no significant difference was observed in Groups 1 and 2 in any of the scoring systems, while Group 3 showed significant improvements in all scoring systems. CONCLUSION: Treatment with ESWT was superior to other treatments throughout the study and at the final follow-up. In patients receiving CS injections, the clinical outcomes worsened with time, evidenced by the six-month follow-up. Further studies on combined treatment modalities are needed on this subject.

Predictive effect of thiol/disulfide homeostasis dynamics on early pregnancy viability: A case-control study.

Objective: The main aim of this study was to investigate the differences in maternal serum thiol/disulfide homeostasis among women with abortion imminens (AI), missed abortion (MA), and healthy pregnancies during the first trimester. Materials and Methods: This was a prospective case-control study. This study was conducted on pregnant women who visited the Obstetrics Clinic at University of Health Sciences Turkey, Etlik Zübeyde Hanim Gynecology Training and Research Hospital and were diagnosed with either AI or MA during the 6th to 14th weeks of pregnancy. The participants had a normal pregnancy follow-up, no chronic illnesses, and did not take any multivitamin or antioxidant supplements except for folic acid. The study incorporated 33 pregnant women with AI, 36 with MA, and 40 with normal pregnancies. Age, and body mass index were matched across the three groups. This study used a recently developed automated spectrophotometric technique to quantify thiol/disulfide concentrations. Results: The AI group had considerably elevated levels of total thiol and native thiol (SH) compared with the MA group. Nevertheless, there was no notable disparity observed between the group of healthy pregnancies and the other two groups. Serum disulfide (SS) levels did not exhibit any significant variations among the three groups. Similarly, the ratios of SS/SH, SS/total thiol, and SH/total thiol did not show any significant differences between the groups (p>0.05). Conclusion: Patients with MA had decreased levels of total thiol and SH, which possess antioxidant capabilities, compared to the AI group. A decrease in antioxidant levels in the body may contribute to the etiology of MA. When considering our findings alongside existing literature, it remains inconclusive whether the serum thiol-disulfide ratio can predict a healthy pregnancy or MA following AI. Therefore, it is not yet seen as a promising diagnostic tool for assessing pregnancy viability. Additional investigation is required to establish the influence of dynamic thiol/disulfide homeostasis on early pregnancy loss.

Comparison of stress distribution around all-on-four implants of different angulations and zygoma implants: a 7-model finite element analysis.

BACKGROUND: In recent years, zygomatic implants and the all-on-four treatment concept have been increasingly preferred for rehabilitation of atrophic maxillae. However, debate continues regarding the optimal configuration and angulation of the implants. The aim of this study was to analyze the biomechanical stress in implants and peri-implant bone in an edentulous maxilla with zygomatic implants and the all-on-four concept, using multiple implant configurations. METHODS: A total of 7 models consisting different combinations of 4-tilted dental implants and zygomatic implants were included in the study. In each model, a total of 200 N perpendicular to the posterior teeth and 50 N with 45° to the lateral tooth were applied. A finite element analysis was performed for determination of stress distribution on implants and peri-implant bone for each model. RESULTS: Higher stress values were observed in both cortical and trabecular bone around the 45°-tilted posterior implants in all-on-four models when compared to zygomatic implants. In cortical bone, the highest stress was established in an all-on-four model including 45°-tilted posterior implant with 4,346 megapascal (MPa), while the lowest stress was determined in the model including anterior dental implant combined with zygomatic implants with 0.817 MPa. In trabecular bone, the highest stress was determined in an all-on-four model including 30°-tilted posterior implant with 0.872 MPa while the lowest stress was observed in quad-zygoma model with 0.119 MPa. Regarding von Mises values, the highest stress among anterior implants was observed in an all-on-four model including 17° buccally tilted anterior implant with 38.141 MPa, while the lowest was in the including anterior dental implant combined with zygomatic implants with 20,446 MPa. Among posterior implants, the highest von Mises value was observed in the all-on-four model including 30°-tilted posterior implant with 97.002 MPa and the lowest stress was in quad zygoma model with 35.802 MPa. CONCLUSIONS: Within the limits of the present study, the use of zygoma implants may provide benefit in decreasing biomechanical stress around both dental and zygoma implants. Regarding the all-on-four concept, a 17° buccal angulation of anterior implants may not cause a significant stress increase while tilting the posterior implant from 30° to 45° may cause an increase in the stress around these implants.

Outcomes of ultraminipercutaneous nephrolithotomy in infants: our experiences at a single center in an endemic region.

OBJECTIVE: In this study, we aimed to contribute to the literature by sharing the perioperative and postoperative outcomes of infants (0-24 months) who underwent ultra-mini percutaneous nephrolithotomy (PNL) for kidney stones in our clinic. METHODS: Infants under 24 months old with kidney stones of 2 cm and larger, who applied to our clinic between January 2018 and May 2023, were included in the study. The patients' demographic and clinical characteristics were obtained from the medical records. The collected data were analyzed retrospectively. RESULTS: A total of 26 patients were included in the study. The mean age of the patients was 17.3 ± 3.90 (12-24) months. The mean operation time was 50.7 ± 6.43 min. The mean stone size was 2.66 ± 0.59 cm. Stone-free was achieved in 23 patients (88.5%). In one patient (3.8%) with residual fragments, SWL was performed, and in two patients (7.7%), RIRS was performed to achieve stone-free. Postoperatively, fever was observed in 3 patients (11.5%). There were no patients requiring blood transfusion. CONCLUSIONS: In experienced centers, ultra-mini-PNL performed by experienced surgeons is an effective and reliable treatment option for infants under 24 months of age with kidney stones larger than 2 cm. It provides high-stone clearance rates and low complication rates.

Don't miss it: Extremity-located cyst hydatid may mimic soft tissue tumors.

OBJECTIVES: In this study, we present our experience in patients with hydatid cysts located intramuscularly. PATIENTS AND METHODS: Between May 2018 and May 2023, a total of 11 patients (3 males, 8 females; mean age: 29.1±13.6 years; range, 8 to 56 years) with intramuscular hydatid cysts were retrospectively analyzed. Demographic data, laboratory values, serological test results, location and size of the cyst, radiological imaging findings, and complications were recorded. RESULTS: The mean follow-up was 44.3±17.3 (range, 5 to 60) months. The mean mass size at the time of admission was 5.4±3.3 (range, 2 to 14) cm. Serologic tests were positive in the majority of cases (72.7%). Eosinophilia was negative in 72.7% patients. The rate of isolated muscle involvement was 81.8%. The rate of lower extremity involvement was 72.7%. The most common involvement was leg (36.4%), thigh (18.2%), and shoulder (18.2%). One patient developed compartment syndrome after cyst rupture during neoadjuvant antihelmintic therapy. There was no recurrence in any of the patients. CONCLUSION: Hydatid cysts should be considered in the differential diagnosis of slowly growing, deeply located, painless soft tissue masses, particularly in endemic areas. Although it is a rare complication, compartment syndrome may develop after spontaneous cyst rupture. Neoadjuvant antihelmintic chemotherapy can reduce complications. The combination of total surgical excision and chemotherapy yields successful results in the treatment of hydatid cysts located in the muscle.

Comparison of the effectiveness of the WALANT method in soft tissue and bone tissue surgeries in lower extremities.

OBJECTIVES: This study aims to investigate the effectiveness of wide-awake local anesthesia with no tourniquet (WALANT) technique in both bony and soft tissue procedures in lower extremities. PATIENTS AND METHODS: Between January 2021 and December 2022, a total of 29 patients (20 males, 9 females; mean age: 34.6±20.2 years; range, 14 to 82 years) who were operated for lower extremity pathologies with the WALANT technique in our clinic were included. The patients were divided into two groups: lower extremity soft tissue surgeries in Group A (n=10) and bone tissue surgeries in Group B (n=19). Postoperative pain onset time, pain score, the amount of intraoperative bleeding, need for additional solution, use of cautery, and the amount of bleeding in the surgical field were compared within groups. The Visual Analog Scale (VAS) was used to evaluate pain. RESULTS: There was no significant difference between the two groups in terms of age (p=0.265), sex (p=0.107), and surgical side (p=0.700). There was no significant difference between the two groups in terms of intraoperative bleeding at the discretion of the surgeon (p=0.701). There was no significant difference in the use of additional solution (p=0.105), cautery usage (p=0.522), pain onset time (p=0.636), and VAS scores (p=0.735) between the two groups. CONCLUSION: Our study results suggest that the WALANT technique is an effective and safe method in selected lower extremity surgeries. It is of utmost importance to apply the technique correctly to prevent complications that may occur.

Comparison of unilateral and bilateral microdissection testicular sperm extraction (MD-TESE) in patients with non-obstructive azoospermia: a prospective study.

OBJECTIVE: To compare sperm retrieval rates between unilateral and bilateral microdissection testicular sperm extraction (MD-TESE) procedures in patients with non-obstructive azoospermia and to contribute to the literature by comparing them with literature data. METHODS: This prospective study included 84 males with primary infertility who had azoospermic NOA, who had been married for at least one year, and whose female partners did not have a history of infertility. The study was conducted between January 2019 and January 2020. MD-TESE was applied bilaterally to 48% (n:41) (Group 1) and unilaterally to 52% (n:43) (Group 2) of the patients, and sperm retrieval rates were compared. RESULTS: There was no statistically significant difference between Group 1 patients and Group 2 patients in terms of sperm availability (61%, 56.5%, p=0.495, respectively). In addition, while no complications were observed in unilateral MD-TESEs, 3 complications were observed in bilateral MD-TESEs. CONCLUSIONS: In our study, it was determined that there was no significant difference between the groups in terms of sperm availability in patients with NOA. Considering the operative time and complication rates of bilateral MD-TESE in patients diagnosed with NOA and the possible MD-TESE procedures that may be performed later, we believe that unilateral MD TESE is a more preferable procedure for the patient and surgeon in this patient group.

Pain relief and functional improvement provided by extracorporeal shock wave therapy in plantar fasciitis is better than corticosteroid injection and kinesio taping: A randomized trial.

Objectives: This study aimed to evaluate the results of extracorporeal shock wave therapy (ESWT), corticosteroid injection (CI), and kinesio taping (KT) in terms of pain and function in plantar fasciitis (PF). Patients and methods: In this prospective study, 90 feet of 64 patients (11 males, 53 females; mean age: 38.3±10.4 years; range, 22 to 70 years) who presented with chronic PF between November 2021 and March 2022 were evaluated. The patients were randomized to three groups, with 30 feet in each group: the CI group, the ESWT group, and the KT group. Each group received only the respective treatment modalities assigned to their group. Pain assessment of the patients before the treatment and at six weeks, three months, and six months was evaluated with the Visual Analog Scale (VAS), and their functions were evaluated with the American Orthopedic Foot and Ankle Society (AOFAS) score. Results: There was no statistical difference in the demographic data (age, body mass index, and VAS; all p>0.05). At six weeks, VAS was statistically significantly lower in the CI group compared to the other groups (p<0.001), but there was no difference in AOFAS between the groups (p=0.666). At three months, there was no statistical difference between the groups regarding VAS (p=0.311), while the AOFAS was higher in the ESWT group (p=0.006). At six months, VAS was lower (p<0.001) and AOFAS was higher (p=0.003) in the ESWT group. Conclusion: All three commonly used treatment modalities, ESWT, CI, and KT, are effective in reducing pain and increasing function in chronic PF. However, while CIs can be more effective in relieving pain in the early period, the most significant improvement at the end of the sixth month was achieved by ESWT.

Evaluation of oxidative stress in degenerative rotator cuff tears.

BACKGROUND: Oxidative stress occurs as a result of the disruption of the balance between the formations of reactive oxygen species and antioxidant defense mechanisms during the conversion of nutrients into energy. Increased body oxidative stress has been reported to be involved in the etiology of several degenerative and chronic diseases. We hypothesized that the body oxidative stress level is higher in patients with atraumatic degenerative rotator cuff tear than that in healthy individuals. METHODS: The patients who underwent arthroscopic repair for atraumatic, degenerative rotator cuff tear were prospectively evaluated. A total of 30 patients (group 1, 19 females and 11 males; mean age: 57.33 ± 6.96 years; range: 50-77 years) and 30 healthy individuals (group 2, 18 females and 12 males; mean age: 56.77 ± 6 years; range: 51-72 years) were included in the study. The Constant and American Shoulder and Elbow Surgeons scoring systems were used to evaluate the clinical outcomes. Serum oxidative stress parameters of the patients and the control group were biochemically evaluated. Accordingly, thiol/disulfide (DS) balance (DS/native thiol [NT], DS/total thiol [TT]), Total Oxidant Status (TOS), oxidative stress index, and nuclear factor erythroid-2-associated factor-2 values were used as the biochemical parameters indicating an increase in the serum oxidative stress level. Total antioxidant status and NT/TT values served as the biochemical parameters indicating a decrease in the serum oxidative stress level. RESULTS: The study follow-up duration was 12 months. A statistically significant increase was observed in American Shoulder and Elbow Surgeons and Constant scores of patients who underwent arthroscopic rotator cuff repair relative to that during the preoperative period (P = .01). The values of biochemical parameters (DS/NT, DS/TT, TOS, oxidative stress index, and nuclear factor erythroid-2-associated factor-2), which indicated an increase in the serum oxidative stress, were significantly higher in preoperative patients than those in postoperative patients, albeit the control group values were significantly lower than those of the postoperative patients. The biochemical parameters (NT/TT and total antioxidant status) indicating a decrease in the serum oxidative stress levels were significantly higher in the postoperative patients than those in the preoperative patients and significantly lower than those in the control group. CONCLUSION: High levels of markers indicating an increase in the serum oxidative stress in patients with degenerative rotator cuff rupture suggested that TOS may be involved in the etiopathogenesis of rotator cuff degeneration. Although the oxidative load decreases during the postoperative period, the fact that it is still higher than that in healthy individuals supports this claim.

Comparative evaluation of the efficacy of ozone therapy and low level laser therapy on oral mucosal wound healing in rat experimental model.

OBJECTIVE: The aim of the present study was to evaluate and compare the effectiveness of ozone therapy and low-level laser therapy (LLLT) on healing of oral mucosal wounds in rats through histological assessment. METHODS: Thirty male Wistar rats were employed in this study. Following a 5-mm surgical wound created on the buccal mucosa, the rats were randomly distributed into 3 groups of 10: (1) ozone group (treated with topical gaseous ozone), (2) laser group (treated with LLLT), and (3) control group (received no treatment). Following the sacrifice of rats on day 21, samples were taken from rats' buccal mucosa for histological assay and scoring. The data were analyzed using Mann-Whitney test. RESULTS: Ozone and laser groups demonstrated reduced acute inflammation scores compared to control group (p=.01), while no significant differences were observed between the ozone and laser groups (p = 1.00). Similarly, ozone and laser groups showed higher histological tissue repair scores than the control group (p=.00), and no difference was found between ozone and laser groups (p=.76). On the other hand, no significant difference in expression of TNF-α (p=.33) and TGF-ß1 (p=.13) was identified between ozone, laser and control samples. CONCLUSION: The present study demonstrated that both adjunctive ozone therapy and LLLT with a 940 nm diode laser provided significant improvement in parameters of acute inflammation and tissue repair in surgical oral mucosal wounds in rats.

Comparing the Effects of 2D and 3D Imaging Systems on Laparoscopic Pyeloplasty Outcomes in the Treatment of Adult Ureteropelvic Junction Obstruction.

Background: The aim of this study was to compare the efficacy, safety, and the clinical and perioperative outcomes of two-dimensional (2D) and three-dimensional (3D) laparoscopic imaging systems in adult patients undergoing laparoscopic pyeloplasty in our clinics due to ureteropelvic junction (UPJ) obstruction. Methods: A total of 46 adult patients who had undergone laparoscopic pyeloplasty due to UPJ obstruction were included in the study. Cases that had undergone the operation before January 2019 were retrospectively evaluated with the 2D imaging systems. Cases after that date were evaluated by using the 3D imaging systems, and the operative, perioperative, and postoperative findings of these patients were recorded prospectively. Patients who had undergone laparoscopic pyeloplasty were classified into two groups as the "2D group" and the "3D group." To standardize the preoperative findings, the cases that were operated by a single surgeon experienced in both 2D and 3D imaging systems were included in the study. The demographic characteristics and the clinical findings of the patients were compared between the groups. Results: A total of 41 patients were included in the study. The mean age was 27.7 ± 9.17 years. Among the patients, 23 (56.1%) were in the 2D group and 18 (43.9%) were in the 3D group. No statistically significant difference was observed between groups with regard to the demographic characteristics of the patients. According to the perioperative and postoperative findings of the patients, the duration of the operation was significantly shorter in the 3D group. Conclusion: The duration of the operation was significantly reduced in the 3D image-guided laparoscopic pyeloplasty in the treatment of UPJ obstruction of the adult, compared with 2D image-guided operations. The 3D imaging systems provide a better image quality, an important convenience in intraoperative saturation, and low rates of complication in laparoscopic pyeloplasty, and they may be used safely and effectively.

Comparison of Prostate Biopsy Using Multiparametric Magnetic Resonance Imaging in Patients with Prostate Biopsy Indications.

OBJECTIVE: This article aims to evaluate the efficacy of multiparametric magnetic resonance imaging before standard tru-cut biopsy in making prostate cancer diagnosis. MATERIALS AND METHODS: A total of 160 patients with prostate biopsy indications were prospectively evaluated between May 2017 and October 2018. Multiparametric magnetic resonance imaging was taken after obtaining a written informed consent from all patients. Cognitive transrectal ultrasound-guided biopsy was performed based on multiparametric magnetic resonance imaging results. Standard tru-cut biopsy was included to reduce false-negative rate. Statistical analysis was performed using the Statistical Package for Social Sciences version 20.0 software. RESULTS: The mean age of the patients was 65.94 ± 7.90 (48-84) years. Around 19.37% of the patients had a specificity in the digital rectal exam. The mean prostate-specific antigen value of the patients with adenocarcinoma was 42.1 ng/mL and it was 10.2 ng/mL in patients with benign prostate hyperplasia. It was observed that the prostate-specific antigen values in prostatic adenocarcinomas were significantly higher than those in benign prostate hyperplasia (P < .001). The results of multiparametric magnetic resonance imaging and the biopsy were 100% similar in terms of zones in patients with adenocarcinoma. All of the biopsy results of the patients who were evaluated to have normal prostate tissue in multiparametric magnetic resonance imaging were evaluated as benign prostate hyperplasia; on the other hand, 13.6% of PI-RADS 2 lesions, 14% of PI-RADS 3 lesions, 31.8% of PI-RADS 4 lesions, and 85.7% of PI-RADS 5 lesions were determined to be adenocarcinoma. It was observed that the prevalence of adenocarcinoma increased as the risk elevated in multiparametric magnetic resonance imaging (P < .001). CONCLUSION: Multiparametric magnetic resonance imaging evaluated by experienced radiologists may be instructive of urologists and reduce the need for unnecessary biopsies.

Desires and attitudes of outpatients and physicians regarding the use of teleurology during the pandemic: a prospective survey study.

OBJECTIVE: It is not known to date how many patients admitted to urology outpatient clinics are willing to use telemedicine. We aimed to investigate knowledge levels and attitudes concerning the utilization of teleurology by patients applying to urology outpatient clinics. METHODS: This prospective multicentre survey study included 334 patients aged 18-65 years who applied to an urology outpatient clinics. The patients were asked questions about their attitudes and expectations regarding teleurology. Diseases were divided into seven subgroups due to the broad spectrum of diagnoses. Physicians' and patients' opinions on whether it was possible to manage the current medical condition via teleurology were recorded. RESULTS: 69.5% of patients stated that they had sufficient technical skills to use teleurology by themselves for medical examination. 55.4% of patients and 78.4% of physicians responded that the existing complaints were suitable for teleurology. Both patients and physicians deemed genital system diseases and urinary tract infections suitable for teleurology (p<0.001, p<0.001 for physicians, and p<0.001, p<0.001 for patients), whereas urine transport, storage and emptying disorders (p=0.003) and benign prostatic hyperplasia (p=0.029) were deemed to be suitable for teleurology only by the physicians. CONCLUSION: Our study shows that (i) the majority of our patient population has a telecommunications infrastructure suitable for teleurology, (ii) teleurology has aroused interest among patients, particularly during the pandemic period, and (iii) physicians and patients have high expectations that the problem can be solved with teleurology in suitable patients.

Evaluation of avascular necrosis risk factors after closed reduction for developmental dysplasia of the hip before walking age.

Avascular necrosis (AVN) of the femoral head is one of the most important complications after closed reduction and spica cast application in developmental dysplasia of the hip (DDH) treatment. This study aims to put forth the impact of closed reduction age and other factors which can cause AVN. Inclusion criteria of the study were: closed reduction and spica cast application before walking age (12 months) and minimum 2 years duration of follow-up. The presence of femoral head ossific nucleus, International Hip Dysplasia Institute (IHDI) score, acetabular indices and AVN were evaluated from radiographies. Hip abduction angles were evaluated on CT images. The absence of the ossific nucleus at the closed reduction time and preoperative IHDI grade were not significant risk factors for AVN (respectively OR = 2.83; 95% CI, 0.99-8.07; P = 0.052; OR = 2.5; 95% CI, 0.85-7.32; P = 0.094). For the patients older than 10 months, (1) the absence of the ossific nucleus was a significant risk factor for grade 2 or higher AVN according to the Bucholz Ogden criteria (P = 0.020) and (2) the higher preoperative IHDI grade (IHDI 3-4) was a significant risk factor for AVN (P = 0.032). AVN of the femoral head was a significant risk factor for fair or poor clinical outcome (P = 0.001). It is not reasonable to wait for radiological visibility of the ossific nucleus to prevent femoral head AVN before applying closed reduction and spica cast, irrespective of the age interval.

Variation of Serum PSA Levels in COVID-19 Infected Male Patients with Benign Prostatic Hyperplasia (BPH): A Prospective Cohort Studys.

OBJECTIVE: To investigate the effect of SARS CoV-2 on serum total PSA levels in men with BPH diagnosed with COVID-19. METHODS: The PSA (Kit: Immunoassay Program- Cycle 18, Siemens Atellica IM Analyzer) levels in patients who had had a PSA check at least 3 months, but no more than 6 months, prior to diagnosis of acute COVID-19 infection, were examined retrospectively. PSA levels were measured and recorded from these patients on the first day of diagnosis of COVID-19. These patients were called back for urology outpatient follow-up at the third month after the end of the COVID-19 treatment. PSA levels measured in the pre-COVID-19 period, during the period of active infection with COVID-19, and in the post-COVID-19 period were compared. RESULTS: In total, 91 patients had a serum PSA level of 1.58 ± 1.09 ng/mL in the pre-COVID-19 period, a serum PSA level of 4.34 ± 3.78 ng/mL measured in the COVID-19 period and 2.09 ± 2.70 ng/mL in the post-COVID-19 period. It was determined that the serum PSA level measured during active COVID-19 infection was statistically significantly higher than the PSA levels measured according to the pre-COVID-19 period and the post-COVID-19 period (P < .001, P < .001; respectively). CONCLUSION: SARS-CoV-2 infection in men diagnosed with BPH causes significant increases in PSA levels during the active period of the disease. Measurement of PSA values used in the diagnosis, differential diagnosis, and follow-up of prostate diseases in the acute period of infection and in the early period after infection treatment may cause false evaluations that may affect the diagnosis and treatment steps of prostate diseases in these patients.

The relationship of serum testosterone levels with the clinical course and prognosis of COVID-19 disease in male patients: A prospective study.

BACKGROUND: A potential role of testosterone among sex hormones has been hypothesized in identifying sex-related differences in the clinical consequences of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Due to the high global prevalence of hypogonadism, the relationship between hypogonadism and SARS-CoV-2 infection outcomes deserves an in-depth study. OBJECTIVE: The present study aimed to investigate the relationship of serum testosterone with other laboratory parameters on the prognosis of coronavirus disease-19 (COVID-19) in male patients with COVID-19 diagnosis. MATERIALS AND METHODS: This prospective cohort study included 358 male patients diagnosed with COVID-19 and 92 COVID-19 negative patients admitted to the urology outpatient clinics as a control group. The COVID-19 patients were divided into groups according to prognosis (mild-moderate and severe group), lung involvement in chest computed tomography (<50% and >50%), intensive care unit needs, and survival. RESULTS: The measured serum total testosterone level of the COVID-19 patients group was found to be significantly lower than that of the control group (median, 140 ng/dl; range, 0.21-328, 322 ng/dl; range, median, 125-674, p < 0.001, respectively). The serum TT levels were statistically significantly lower in severe COVID-19 patients compared to mild-moderate COVID-19 patients (median, 85.1 ng/dl; range, 0.21-532, median, 315 ng/dl; range, 0.88-486, p < 0.001, respectively), in COVID-19 patients in need of intensive care compared to COVID-19 patients who did not need intensive care (median, 64.0 ng/dl; range, 0.21-337, median, 286 ng/dl; range, 0.88-532 p < 0.001, respectively), and in COVID-19 patients who died compared to survivors (median, 82.9 ng/dl; range, 2.63-165, median, 166 ng/dl; range, 0.21-532, p < 0.001, respectively). DISCUSSION AND CONCLUSION: Our data are compatible with low TT levels playing a role on the pathogenesis of the disease in Covid-19 patients with poor prognosis and a mortal course and may guide clinicians in determining the clinical course of the disease.

Concurrent Inguinal Hernia Repair During Robot-Assisted Transperitoneal Radical Prostatectomy: Single Center Experience.

OBJECTIVE: To evaluate outcomes of concurrent inguinal hernia (IH) repair with mesh during transperitoneal robot-assisted radical prostatectomy (RARP). MATERIAL AND METHODS: Data of 26 patients (31 procedures) undergoing IH repair concurrently with RARP between January 2017 and January 2020 were evaluated retrospectively. Patients' demographics, intraoperative and postoperative variables were recorded. Patients were assessed based on prostate-specific antigen recurrence, IH recurrence, mesh infection, seroma formation and groin pain quarterly in the first year, and every six month thereafter. RESULTS: The median age was 64.5 years in our population. IH was detected preoperatively in 46.2% of patients (n = 12) and intraoperatively in 53.8% (n = 14). Twenty-one (80.8%) patients (11 of them had right IH and 10 of them had left IH) had unilateral hernias and 5 patients (19.2%) had bilateral hernias. Twenty-three (88.4%) IHs were direct, three (11.6%) were indirect. The median operative time and estimated blood loss were 192.5 (range: 140-250) min and 100 (range: 10-170) mL, respectively. The median duration of IH repair, time of drainage, length of hospitalization, and catheterization were 32.5 (range: 14-40) min. 2 (range: 2-6) days, 6 (range: 5-8) days and 7 (range: 5-7) days, respectively. No perioperative complication due to RARP or IH repair was observed. During a median follow-up time was 18 months, no scrotal hematoma, seroma formation or mesh infection was identified. CONCLUSION: IH repair performed during the same session at RARP is a safe and applicable procedure.

Promising results of surgical management of advanced medication related osteonecrosis of the jaws using adjunctive leukocyte and platelet rich fibrin.

BACKGROUND: Leukocyte- and platelet-rich fibrin (L-PRF) is an autologous matrix scaffold which regulates inflammation by stimulating cytokines and growth factors that are involved in the immune response. L-PRF is suggested as a viable adjunctive method to surgical interventions due to its advantages on tissue healing. This study aims to retrospectively evaluate the adjunctive role of L-PRF in surgically treated medication-related osteonecrosis of the jaws (MRONJ) patients. METHODS: Between January 2012 and December 2020, patients with AAOMS stage II and III MRONJ lesions, who were treated surgically with adjunctive use of L-PRF in the authors' institution were enrolled. Surgical interventions consisted of either marginal resection or sequestrectomy with peripheral ostectomy (SPO) or curettage and L-PRF application. Medical records of these patients were retrospectively reviewed and healing was assessed according to certain parameters including mucosal closure and presence of infection, exposed bone, fistula or radiologic markers of disease progression for a minimum of 12 months. RESULTS: Thirteen patients (7 women and 6 men) with an average age of 72.4 years (± 10.61, range 54-84) were included in the study, nine of whom had AAOMS stage III and four stage II MRONJ. Three patients had a marginal resection, nine patients had sequestrectomy with peripheral ostectomy (SPO) and one patient underwent a curettage procedure. All marginal resection and six SPO patients showed complete healing while four patients, who had SPO or curettage experienced incomplete healing. Mean follow up was 20.1 ± 18.29 months. CONCLUSION: The use of L-PRF may be a favorable adjunctive option in the treatment of MRONJ owing to its favorable effects on tissue repair, ease of application, minimally invasive and cost-effective character and autogenous nature. Trial registration Retrospectively registered.

Effects of developmental dysplasia of the hip screening program on the treatment strategies: A retrospective study from a tertiary care hospital in the southeast region of Turkey.

OBJECTIVE: The aim of this study was to investigate the effects of the developmental dysplasia of the hip screening program on the treatment procedures in a tertiary health care center. METHODS: We retrospectively reviewed all the DDH patients between 2012 and 2019 from the operating theatre records. The patients were separated based on the year of treatment. The rates of each treatment modality were determined respectively from 2012 to 2019, and Pavlik harness usage of the patients were queried. The changes in the rates of several surgical interventions after the start of screening program were identified. RESULTS: Between 2012 and 2019, 831 interventions were applied to 711 DDH patients. Closed Reduction (CR) is the least invasive treatment method, and it increased significantly from 20% to 46%. The rate of Open Reductions (OR) also increased from 3% to 9% at this time period, but it was statistically insignificant. Conversely, Pemberton-Salter Osteotomy (PSO) and Dega-Chiari Osteotomy (DCO) rates decreased significantly (41% to 28% and 9% to 0%, respectively). The rate of Pemberton- Salter osteotomy with femoral shortening (PSO-FS) rate decreased insignificantly from 27% to 20%. In patients that used Pavlik harness, the most common intervention was CR (83%). In CR group, the screened newborn rate increased more than two times from 2012 to 2019. CONCLUSION: The results of this study have shown that after the initiation of the screening program for DDH, less invasive treatment modalities such as CR and OR interventions increased, and major bony procedures such as PSO, PSO-FS and DCO interventions decreased. Furthermore, as the screening program advanced, CR rate and the use of Pavlik harness rate in CR interventions increased. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.
