Short-term Follow-up Of Patients Research Articles

Malignant Transformation of Benign Meningiomas with or without Radiotherapy

Most meningiomas are benign, slow growing tumors, which rarely progress to a higher grade. The incidence rate of malignant progression is estimated to be 2.98/1000 patient-year. However, non-skull base location is a significant risk factor for progression. The median time to malignant progression is 4.3 years; however, the cumulative rate of progression approaches a plateau after 10 years. Although radiosurgery does not appear to increase the incidence rate(0.5/1000 patient-year), exact comparisons have been difficult because of differences in study populations. The median time to progression is 7.0 years from initial diagnosis and 5.0 years from radiosurgery. The cumulative rate appears to increase even after 10 years. The risk of malignant transformation after radiotherapy may increase in patients with tumor-prone syndromes, with some controversies regarding patients with neurofibromatosis type 2. Although short term follow-up in patients with meningioma suggests that radiosurgery is safe, there is uncertainty regarding its use in pediatric patients, and those with tumor-prone syndromes.

Determining minimal clinically important difference and patient-acceptable symptom state after arthroscopic isolated subscapularis repair

BackgroundMinimal Clinically Important Difference (MCID) and Patient Acceptable Symptomatic State (PASS) have emerged as patient-based treatment assessments. However, these have not been investigated in patients undergoing arthroscopic isolated subscapularis repair (AISR). The primary purpose of this study was to determine the MCID and PASS for commonly used patient-reported outcomes in individuals who underwent AISR. The secondary purpose was to assess potential associations between preoperative and intraoperative patient characteristics and the MCID and PASS. MethodsA retrospective analysis was conducted on prospectively collected data for patients who underwent primary AISR between 2011 and 2021 at a single institution, with minimum 2-year postoperative follow-up. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), and Visual Analog Scale (VAS) pain scale. The MCID was determined using the distribution-based method, while PASS was evaluated using AUC (Area Under the Curve) analysis. To investigate the relationship between preoperative variables and the achievement of MCID and PASS thresholds, Pearson and Spearman coefficient analyses were employed for continuous and non-continuous variables, respectively. ResultsA total of 77 patients with a mean follow-up of 58.1 months were included in the study. The calculated MCID values for VAS pain, ASES, and SSV were 1.2, 10.2, and 13.2, respectively. The PASS values for VAS pain, ASES, and SSV were 2.1, 68.8, and 68, respectively. There was no significant correlation between tear characteristics and the likelihood of achieving a MCID or PASS. Female sex, worker’s compensation status, baseline VAS pain score, and baseline ASES score, exhibited weak negative correlations for achieving PASS for VAS pain and ASES. ConclusionThis study defined the MCID and PASS values for commonly used outcome measures at short-term follow-up in patients undergoing AISR. Tear characteristics do not appear to impact the ability to achieve a MCID or PASS after AISR. Female sex, worker’s compensation claim, and low baseline functional scores have weak negative correlations with the achievement of PASS for VAS pain and ASES scores.

Intra-articular corticosteroid injections provide a clinically relevant benefit compared to placebo only at short-term follow-up in patients with knee osteoarthritis: A systematic review and meta-analysis.

To quantify the clinical relevance of intra-articular corticosteroid effects compared to placebo for the injective treatment of knee osteoarthritis (OA). The PubMed, Cochrane Libraryand Web of Science databases were searched on May3, 2023. This study was conducted in accordance with the PRISMA guidelines. The inclusion criteria were randomized controlled trials (RCTs), published in English, with no time limitation regarding publication date, comparing intra-articular corticosteroids and placebo injections for knee OA. The effects were quantified at short- (≤6 weeks), mid- (>6 weeks and ≤3 months), and long-term (≥6 months) follow-ups. The minimal clinically important difference (MCID) for the outcomes (visual analogue scale for pain - VAS: 1.4, Western Ontario and McMaster University Osteoarthritis Index - WOMAC: 9) was used to interpret the clinical improvement provided by intra-articular corticosteroid injections compared to placebo. The quality of each article was assessed using the Cochrane RoB 2 tool and the GRADE guidelines. Among the 1030 articles retrieved, 11 RCTs (842 patients) were included. A comparison of the two groups revealed statistically significant differences in the improvement of VAS and WOMAC scores in terms of the mean difference (MD); this difference was in favour of corticosteroids at short-term (p < 0.001, MD = -1.6 and p < 0.001, MD = -9.9, respectively) and mid-term follow-ups (p = 0.001, mean MD = -1.3 and p = 0.005, MD = -4.9, respectively). No difference was observed at the long-term follow-up. The MDs between the improvements in the two groups reached the MCID values for the VAS and WOMAC only at the short-term follow-up. The RoB 2 tool and the GRADE evaluations showed the presence of risk of bias and limited quality of evidence. This systematic review and meta-analysis demonstrated that intra-articular corticosteroid injections offer clinically perceivable pain relief and functional improvement higher than the placebo effect only at short-term follow-up in patients affected by knee OA, with benefits losing clinical relevance already after 6 weeks. These results, together with the low number and the limited quality of the RCTscomparing this treatment with placebo, question the indication for the use of corticosteroid injections in clinical practice for the treatment of knee OA.

Direct Exposure to Outdoor Air Pollution Worsens the Functional Status of Stroke Patients Treated with Mechanical Thrombectomy

Background The effect of air pollutants on the functional status of stroke patients in short-term follow-up is unknown. The aim of this study was to evaluate the effect of air pollution occurring in the stroke period and during hospitalization on the functional status of patients undergoing mechanical thrombectomy (MT). Methods Our study included stroke patients for which the individual-level exposure to ambient levels of O3, CO, SO2, NO2, PM2.5, and PM10 during the acute stroke period was assessed. The correlations between the air pollutants’ concentration and the patients’ functional state were analyzed. A total of 499 stroke patients (mean age: 70) were qualified. Results The CO concentration at day of stroke onset was found to be significant regarding the functional state of patients on the 10th day (OR 0.014 95% CI 0–0.908, p = 0.048). The parameters which increased the risk of death in the first 10 days were as follows: NIHSS (OR 1.27; 95% CI 1.15–1.42; p &lt; 0.001), intracranial bleeding (OR 4.08; 95% CI 1.75–9.76; p = 0.001), and SO2 concentration on day 2 (OR 1.21; 95% CI 1.02–1.47; p = 0.03). The parameters which increased the mortality rate within 90 days include age (OR 1.07; 95% CI 1.02–1.13; p = 0.005) and NIHSS (OR 1.37; 95% CI 1.19–1.63; p &lt; 0.001). Conclusions Exposure to air pollution with CO and SO2 during the acute stroke phase has adverse effects on the patients’ functional status. A combination of parameters, such as neurological state, hemorrhagic transformation, and SO2 exposure, is unfavorable in terms of the risk of death during a hospitalization due to stroke. The risk of a worsened functional status of patients in the first month of stroke rises along with the increase in particulate matter concentrations within the first days of stroke.

Role of Endoscopic Endonasal Approach for GH-Secreting Tumors.

Endoscopic endonasal approach (EEA) plays a central role in the treatment of GH-secreting pituitary adenomas (PAs)/pituitary neuroendocrine tumors (PitNETs), allowing to treat not only micro- or regular macro- PAs/PitNEts, but also more complex cases, otherwise requiring a transcranial or other open approaches. All consecutive cases of GH-secreting PAs/PitNETs treated by EEA from May 1998 to June 2023 at our Institution were included. Patients clinical, bio-chemical, and neuroradiological features were considered, as well the surgical approach adopted for each case and its related complications. Surgical and endocrinological was determined at 3 months follow-up. Our series is composed of 356 patients (57.6% females, mean age: 47 ± 12.7 years old): 118 (33.1%) micro-, 180 (50.6%) regular macro- and 58 (16.3%) irregular/invasive PAs/PitNEts. Radical removal was achieved in 296 (83.1%) patients and biochemical control in 270 (75.8%) at 3 months follow-up. Better surgical results and higher hypersecretion remission rate were demonstrated for micro- and regular endo-/endosuprasellar PAs/PitNETs than for irregular ones (respectively p < 0.001 and p < 0.001). Higher complication and endocrinological function permanent worsening rates were observed in the group of tumors with a supradiaphragmatic extension. Our study confirmed the efficacy and safety of EEA in the short-term follow-up in patients with GH-secreting PAs/PitNETs. This approach has demonstrated to be highly versatile, allowing to tailor the surgery to each specific case, with the aim of obtaining the radical removal and consequently the biochemical remission with minimal complications, patients discomfort, or endocrinological sequelae in a large number of cases.

Paper 68: Outcomes following Extracorporeal Shockwave Therapy for chronic Achilles tendinopathy at short to mid-term follow-up

Objectives: The purpose of this retrospective clinical study was to evaluate outcomes following extracorporeal shockwave therapy (ESWT) for the treatment of Achilles tendinopathy. Subgroup analysis was conducted to identify predictors of poor outcomes. Methods: This retrospective cohort study included existing clinical data from 74 patients from a single academic institution. Patients greater than 16 years of old who underwent ESWT for Achilles tendinopathy in the office setting between 3/3/2017 to 8/2/2022 were included. Data collected included: patient demographics, co-morbidities, treatment characteristics, Victorian institute of sports assessment – Achilles (VISA-A) scoring tool, visual analog scale (VAS), magnetic resonance imaging data, return to play (RTP) data and failures were recorded. Failure was defined as no improvement in VISA-A nor VAS scores or surgical intervention. For these data, mean and standard deviation were calculated, and paired samples T-tests and Welch’s T-tests were performed on clinical outcome scores. Results: In total, 74 patients (91 heels) with a mean age of 54.1 ± 14.0 years and BMI of 27.3 ± 4.5 kg/m2 underwent ESWT for Achilles tendinopathy at a mean follow-up of 25.7 ± 15.0 months. Eighteen patients were in the non-insertional Achilles tendinopathy (NAT) cohort and 56 patients were in the insertional Achilles tendinopathy (IAT) cohort. Both NAT and IAT cohorts had a similar improvement in VISA-A score (p=0.365) and VAS scores (p=0.65). A shorter return to play time was found in the NAT cohort (1.1 ± 0.9 months) compared to the IAT cohort (2.6 ± 5.7 months) but this was not statistically significant (p=0.34). There was a higher failure rate in the the IAT cohort (50.0%) than the NAT cohort (38.9%). Patients who received platelet-rich plasma (PRP) had a higher failure rate (61.2%) than those who did not receive PRP (39.6%). In the NAT cohort, the failure rate in females was 0.0%. In the IAT cohort, the failure rate in females was 61.9%. Linear regression analysis found that elevated BMI and MRI severity were associated with worse post-ESWT outcomes. Conclusions: This retrospective study demonstrated a high failure rate at short-term follow-up in patients who underwent ESWT for Achilles tendinopathy. Higher failure rates were found in patients with IAT and those who received intratendinous PRP. Predictors of poor outcomes included elevated BMI and MRI severity. Further studies with larger patient cohorts and a longer follow-up are necessary to determine the role of ESWT in the treatment of Achilles tendinopathy.

ANMCO position paper on the management of hypercholesterolaemia in patients with acute coronary syndrome.

Patients suffering from acute coronary syndrome (ACS) present a high risk of recurrence and new adverse cardiovascular events after hospital discharge. Elevated plasma LDL-cholesterol (LDL-C) levels have been shown to be a causal factor for the development of coronary heart disease, and robust clinical evidence has documented that LDL-C levels decrease linearly correlates with a reduction in cardiovascular events. Recent studies have also demonstrated the safety and efficacy of an early and significant reduction in LDL-C levels in patients with ACS. In this position paper, Italian Association of Hospital Cardiologists proposes a decision algorithm on early adoption of lipid-lowering strategies at hospital discharge and short-term follow-up of patients with ACS, in the light of the multiple evidence generated in recent years on the treatment of hypercholesterolaemia and the available therapeutic options, considering current reimbursement criteria.

Evaluation of swallowing in transverse maxillary deficiency patients before and after rapid maxillary expansion.

To evaluate swallowing function in relation to oropharyngeal dysphagia (OD) in adolescents who had transverse maxillary deficiency with posterior crossbite and high-arched palate, before, and after rapid maxillary expansion (RME). Twenty patients (mean age: 13.0 ± 3.1) with bilateral posterior crossbite and high-arched palate (RME group: RMEG) and 20 volunteers (mean age: 13.4 ± 2.6) with Class I crowding without posterior crossbite or high-arched palate (control group: CG) were recruited. OD signs and symptoms were evaluated using the Eating Assessment Tool-10 (EAT-10) questionnaire, patient complaints, and physical examination of swallowing function before (T1) and 7 months after (T2) RME. Additionally, fiberoptic endoscopic evaluation of swallowing (FEES) with water, yogurt, and cracker was performed. In CG, evaluation of swallowing was performed only once, corresponding to T1 of RMEG. Prevalence of OD signs and symptoms based on patient complaints and physical examination of swallowing was low (5%-15%), and nonsignificant differences were observed between CG and RMEG at T1 for these parameters as well as for EAT-10 scores. Total post-swallow pharyngeal residue with yogurt was significantly different between CG and RMEG at T1, with a prevalence of 60% in RMEG (P < .05). There was no significant difference regarding residue with yogurt between T1 and T2 in RMEG (P > .05). Patients with a maxillary transverse deficiency were affected by pharyngeal residue as indicated by FEES, but it did not appear to improve in short-term follow-up in patients treated with RME.

Pancreatic Cancer in Chronic Pancreatitis: Pathogenesis and Diagnostic Approach.

Chronic pancreatitis is one of the main risk factors for pancreatic cancer, but it is a rare event. Inflammation and oncogenes work hand in hand as key promoters of this disease. Tobacco is another co-factor. During alcoholic chronic pancreatitis, the cumulative risk of cancer is estimated at 4% after 15 to 20 years. This cumulative risk is higher in hereditary pancreatitis: 19 and 12% in the case of PRSS1 and SPINK1 mutations, respectively, at an age of 60 years. The diagnosis is difficult due to: (i) clinical symptoms of cancer shared with those of chronic pancreatitis; (ii) the parenchymal and ductal remodeling of chronic pancreatitis rendering imaging analysis difficult; and (iii) differential diagnoses, such as pseudo-tumorous chronic pancreatitis and paraduodenal pancreatitis. Nevertheless, the occurrence of cancer during chronic pancreatitis must be suspected in the case of back pain, weight loss, unbalanced diabetes, and jaundice, despite alcohol withdrawal. Imaging must be systematically reviewed. Endoscopic ultrasound-guided fine-needle biopsy can contribute by targeting suspicious tissue areas with the help of molecular biology (search for KRAS, TP53, CDKN2A, DPC4 mutations). Short-term follow-up of patients is necessary at the clinical and paraclinical levels to try to diagnose cancer at a surgically curable stage. Pancreatic surgery is sometimes necessary if there is any doubt.

The impact of the COVID-19 pandemic on the urology practice in a large tertiary hospital

Objectives: We aimed to reveal how four different areas that are important in the functioning of the urology clinic (outpatient clinic, inpatient clinic, operating room, and consultations) were affected during the COVID-19 pandemic. Methods: Patients admitted to the surgical branches between March 11, 2018 and March 10, 2021 were retrospectively evaluated in terms of their demographic data. The data between these dates were analyzed by dividing the patients into three groups as Groups A, B, and C for the pandemic period, the year before the pandemic, and two years before the pandemic, respectively. Results: A total of 1,222,967 patients were included in the study. During the pandemic period, the number of urology outpatient clinic admissions decreased by more than half compared to the previous years (37,471, 93,582, and 89,031 for Groups A, B, and C, respectively). Admissions to the urology inpatient clinic decreased both numerically and proportionally when compared to the other surgical branches (1,301 [5.1%] for Group A, 3,884 [7.7%] for Group B, and 3,761 [7.7%] for Group C]). While the mortality rate did not change proportionally in the urology clinic in all groups (0.3%), it increased both numerically and proportionally in all surgical branches (339 [1.3%], 304 [0.6%], and 256 [0.5%]). Conclusions: Admissions to the urology clinic were determined to have decreased during the pandemic compared to the pre-pandemic period, especially due to restriction measures taken by countries and concerns about the unknowns of the disease. As a result of this decrease, the number of operations and the number of hospitalized patients were also reduced. Although the mortality rate was not affected in the short-term follow-up of patients, long-term outcomes remain uncertain.

Frozen shoulder after COVID-19 vaccination.

BackgroundThe data on frozen shoulder and shoulder injury related to vaccine administration (SIRVA) after coronavirus disease 2019 (COVID-19) vaccination are absent from the literature. Hence, the purpose of this case series was to describe the clinical presentation and short-term follow-up of patients who developed frozen shoulder after COVID-19 vaccination.MethodsIn the present study, 10 patients (9 women and 1 man) with a mean age of 53 ± 8 years (range, 43-68 years) who presented to the shoulder surgeon’s practice center with painful stiffness of the shoulder after COVID-19 vaccination between June 1 and September 30, 2021, were retrospectively evaluated.ResultsAll 10 patients had normal radiographs and were diagnosed as frozen shoulder. Eight patients (80%) had a comorbidity during presentation (4 patients with hypothyroidism, 3 patients with diabetes mellitus, and 1 patient with prediabetes/hyperglycemia). Symptoms developed immediately after the vaccination in 6 patients (60%), at 48 hours in 1 patient (10%), and at 10 days in 3 patients (30%). The mean pain visual analog scale score was 6.5 ± 1.9 (range, 2.5-8), and both active and passive range of motion were limited in all the patients at the time of presentation.ConclusionThe musculoskeletal specialists who will see such patients with painful shoulder stiffness should be aware of the frozen shoulder diagnosis, which can occur after COVID-19 vaccination, so that such patients can be identified and treated early.

The Relationship between the Connexin 32 and Connexin 43 Genes and the Pretreatment Stage and Short-term Follow-up of Patients with Acute Myeloid Leukemia.

Background: Connexins (Cxs) are gap junction proteins involved in the communication between acute myeloid leukemia (AML) and stromal cells. They consist of intercellular channels termed “connexions”, which can cause uncontrolled cell proliferation if dysregulated. This study aimed to evaluate the expression levels of the Cx32 and Cx43 genes and their correlations with other prognostic markers in patients with AML.Methods: This cross sectional study was performed on peripheral blood samples from 60 newly diagnosed patients with AML and 40 healthy control subjects at Kasr Alainy School of Medicine, Cairo University, from June 2016 to December 2017. The quantitative real-time polymerase chain reaction (qRT-PCR) test was used to examine the relative expression level of Cx43 and Cx32 genes in the patients and the control subjects. The Chi square test or the Fisher exact test was employed to examine the relationship between qualitative variables, while the independent t test or the Mann–Whitney test was employed for quantitative data. All the tests were two-tailed, and a P value of less than 0.05 was considered significant.Results: Among the patients with AML, 65% had a high Cx32 expression level, whereas 63.3% had a low Cx43 expression level. There was a statistically significant difference in the fold change values of Cx32 and Cx43 expression between the patient group and the control group (P=0.009 vs P=0.013, respectively). There was a remarkable association between both Cxs and CD34 and HLA-DR cells.Conclusion: Cx expression in samples may add to the diagnostic workup of AML. Although we found a negative correlation between Cx43 expression and the peripheral blood blast percentage, the response after the first induction of chemotherapy showed no significant relationship with Cx43 and Cx32.

Autoimmune pancreatitis with pancreatic calculi and pseudocyst: a case report

Autoimmune pancreatitis (AIP) is a unique form of pancreatitis often associated with infiltration of immunoglobulin G4-positive cells, a swollen pancreas, and diffuse narrowing of the pancreatic ducts. Unlike acute pancreatitis, AIP is rarely complicated with pseudocysts. Pancreatic calculi, a feature of ordinary chronic pancreatitis, are unusual during short-term follow-up in patients with AIP. We herein describe a 46-year-old man who initially presented with a submucosal tumor of the stomach. The patient was finally diagnosed with AIP accompanied by a pancreatic tail pseudocyst located in the gastric wall and pancreatic calculi by endoscopic ultrasonography-guided fine-needle aspiration. He underwent endoscopic retrograde cholangiopancreatography, pancreatic duct stent placement, and steroid treatment and achieved good clinical and laboratory responses. Although AIP is a common autoimmune disease that responds well to steroids, pseudocysts and pancreatic calculi are rare manifestations of AIP and should be given special attention, especially in patients with disease relapse.

Temperate approach to ASD closure in pulmonary arterial hypertension: the fenestrated patch technique.

The most common CHD in the adult patient population is an atrial septal defect due to its asymptomatic nature in early life. However, when diagnosis and treatment are delayed, pulmonary arterial hypertension may develop as a long-term complication, sometimes before adulthood. The presence of PAH adversely affects the results of surgical treatment and may even eliminate the feasibility of surgery in some patients. In such patients who have high pulmonary artery pressure and pulmonary vascular resistance at the margin of inoperability, the response to the acute vasoreactivity test determines the treatment modality.In our retrospective study, a total of 906 patients who underwent ASD closure between January, 2011 and November, 2020, seven of which had undergone the fenestrated patch procedure after they were identified to have high PAP, but positive AVT test response were included. Short-term follow-up of patients with fenestrated ASD patches revealed decreased pulmonary pressure, regression in NYHA classification, and improvement in symptoms.The fenestrated patch technique should be kept in mind as an option to expand the surgical spectrum in the treatment of patients with high pulmonary pressures, where complete closure is risky. It appears that the fenestrated patch technique is a safe approach in the management of pulmonary hypertension in patients with ASD who have pulmonary hypertension, according to short- and midterm follow-up findings.

Effectiveness of placebo interventions for patients with nonspecific low back pain: a systematic review and meta-analysis.

Little is known about the effectiveness of placebo interventions in patients with nonspecific low back pain (LBP). This systematic review assessed the magnitude of the effects of placebo interventions as compared to no intervention in randomized controlled trials (RCTs) including patients with LBP. Embase, MEDLINE (Ovid), and Cochrane CENTRAL databases were searched from inception to December 5, 2019. Randomized controlled trials comparing placebo intervention vs no intervention in adult patients with nonspecific LBP were included. Pain intensity, physical functioning, and health-related quality of life measured at short-term, medium-term, and long-term follow-up were the outcomes of this review. Twenty-one randomized controlled trials were included; one concerning acute LBP and one subacute LBP, whereas 19 studies reported on chronic LBP. In chronic LBP, placebo interventions were more effective than no intervention at short-term follow-up for pain intensity (standardized mean difference = -0.37, 95% confidence interval [CI] = -0.55 to -0.18, moderate-quality evidence), physical functioning (standardized mean difference -0.19, 95% CI = -0.39-0.01, moderate-quality evidence), and physical quality of life (mean difference = -2.71, 95% CI = -4.71-0.71, high-quality evidence), respectively. These effects were not significant at medium-term follow-up, and no data were available at long-term follow-up. These results show placebo interventions are more effective than no intervention at short-term follow-up in patients with chronic LBP. However, the magnitude of the effects is probably not clinically relevant (approximately 8 points on a 0-100 pain scale). Future research should identify effect modifiers and causal mechanisms explaining the short-term effects of placebo interventions in patients with chronic LBP.

Three-year effects of bariatric surgery on obstructive sleep apnea in patients with obesity grade 1 and 2: a sub-analysis of the GATEWAY trial.

Most of the evidence on bariatric surgery on obstructive sleep apnea (OSA) is based on observational studies and/or short-term follow-up in patients with obesity grade 3. This randomized study compared the effects of roux-en-Y gastric bypass (RYGB) or usual care (UC) on OSA severity in patients with obesity grade 1-2. Mild, moderate, and severe OSA was defined by the apnea-hypopnoea index (AHI): 5-14.9; 15-29.9, and ≥30 events/h, respectively. OSA remission was defined by converting any form of OSA into normal AHI (<5 events/h). After 3-year of follow-up, the body-mass index increased in the UC while decreased in the RYGB group: +1.7 (-1.9; 2.7) versus -10.6 (-12.7; -9.2) kg/m2, respectively. The AHI increased by 5 (-4.2; 12.7) in the UC group while reduced in the RYGB group to -13.2 (-22.7; -7) events/h. UC significantly increase the frequency of moderate OSA (from 15.4 to 46.2%). In contrast, RYGB had a huge impact on reaching no OSA status (from 4.2 to 70.8%) in parallel to a decrease of moderate (from 41.7 to 8.3%) and severe OSA (from 20.8 to 0%). RYGB is an attractive strategy for mid-term OSA remission or decrease moderate-to-severe forms of OSA in patients with obesity grade 1-2.

All-Arthroscopic Hydrogel-Based Autologous Chondrocyte Transplantation in the Knee Joint: Good Clinical and Magnetic Resonance Imaging Outcome After 24 Months

To evaluate subjective and objective clinical and magnetic resonance imaging-based radiologic outcomes after short-term follow-up in patients with focal full-size cartilage lesions of the knee joint treated with all-arthroscopic hydrogel-based autologous chondrocyte transplantation. A retrospective study on patients with isolated focal cartilage defects of the knee joint who were treated with arthroscopically conducted matrix-induced autologous chondrocyte transplantation was performed. Clinical scores were assessed at baseline and final follow-up using the Tegner Score, visual analog scale, the International Knee Documentation Committee, and the 5 subscales of the Knee Injury and Osteoarthritis Outcome Score. Magnetic resonance imaging scans of the treated knee joints were evaluated with the updated MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) 2.0 scoring system at follow-up. Twenty-nine consecutive patients were included in the study. Mean time to follow-up was 24.9 ± 1.1 months. Average visual analog scale decreased significantly from 6.5 ± 3.1 preoperatively to 2.3 ± 1.6 at follow-up (P < .0001). Tegner score increased from 3.1 ± 1.3 to 4.3 ± 1.2 (P < .0001) and the International Knee Documentation Committee from 43.8 ± 21.9 to 64.9 ± 18.9 (P < .0001). Also, all Knee Injury and Osteoarthritis Outcome Score subscales displayed significant improvements. Patients showed similar improvements of nearly all clinical scores independent of the defect size. Average MOCART2.0 score was 70.0 ± 13.6 and 20 patients scored ≥70 points. All 8 patients with large defects (>5 cm2) scored ≥75 points. In this small study, injectable matrix-induced autologous chondrocyte transplantation therapy in the knee joint led to favourable clinical and radiologic short-term results with significant improvements in all clinical scores and MOCART2.0 scores, confirming morphologic integrity of the transplanted chondrocytes. Therefore, this minimally invasive procedure represents a promising operative technique for cartilage regeneration, even for large-diameter lesions. IV, therapeutic case series.

Evolution of Diastolic Dysfunction in Patients with Coronary Slow Flow Phenomenon and Acute Non-ST Segment Elevation Myocardial Infarction.

BACKGROUNDDiastolic function has been reported to be impaired in many patients with coronary slow flow phenomenon (CSFP). CSFP has broad spectrum of clinical presentations, including non-ST elevation myocardial infarction (NSTEMI). We sought to study the short-term evolution of diastolic function in CSFP patients presenting with NSTEMI.METHODSThis study included 92 patients with CSFP and acute NSTEMI. Conventional echocardiography Doppler imaging and tissue Doppler echocardiography imaging were used to evaluate diastolic function during index NSTEMI and after 3 months.RESULTSMean age of study patients was 45.7 ± 6.8 years. The prevalence of diastolic dysfunction (DD) at baseline was 69 patients (75%) and 28 patients (30.4%) at 3 months, p < 0.001. Various diastolic function indices showed significant improvement from baseline to 3 months follow-up. E/Em was 17.32 ± 3.41 at baseline compared to 12.41 ± 5.58 at 3 months, p = 0.039. Septal e′ velocity was 5.67 ± 4.56 cm/s at baseline compared to 7.78 ± 3.22 cm/s at 3 months, p = 0.023. Medications used were not significantly different between those with improved versus unimproved DD.CONCLUSIONSDiastolic function seems to improve over short-term follow-up in patients with CSFP presenting with NSTEMI. This could reflect a transient worsening during acute NSTEMI.

Patient Expectation and Satisfaction After Arthroscopic Debridement for Hip Osteoarthritis

Objective: The purpose of the present study was to evaluate the expectation and satisfaction of patients treated with hip arthroscopy for moderate to advanced hip osteoarthritis. Method: Eighteen patients with Tönnis grade 2 or 3 hip osteoarthritis who were treated with hip arthroscopy and followed up for at least one year, were included in the study. All patients received partial labrum debridement with limited rim excision (3-5mm), chondroplasty and excision of osteophytes/cam lesion. Demographic data, education level, VAS scores, time to the last follow-up, expectation and satisfaction levels were evaluated. Results: There was not any correlation between any parameters tested except a negative correlation between time to follow up and satisfaction level, time to follow-up and satisfaction point. When short-term follow-up patients were compared with longer term follow-up groups, patient satisfaction levels, and scores were higher. Conclusion: Satisfaction levels of patients, treated with arthroscopic debridement for advanced hip osteoarthritis, is dependent on the follow-up time. Patients are satisfied up to 2 years postoperatively.
