Immediate and Follow‐Up Results of Repeat Percutaneous Mitral Balloon Commissurotomy for Restenosis After a Succesful First Procedure

Background: The widespread use of percutaneous mitral commissurotomy (PMC) has led to an increase in restenosis cases. The data regarding follow‐up results of repeat PMC are quite limited. The aim of this retrospective analysis is to evaluate the immediate and midterm results of the second PMC, in patients with symptomatic mitral restenosis after a succesful first procedure. Methods: Twenty patients (95% female, mean age 37 ± 4 years) who have undergone a second PMC, 6.3 ± 2.5 years after a first successful intervention built the study group. All were in sinus rhythm, with a mean Wilkins score of 8.5 ± 1.2. Results: The valve area increased from 1.2 ± 0.2 to 1.9 ± 0.2 cm² and mean gradient decreased from 10.5 ± 3.4 to 6.1 ± 1.1 mmHg. There were no complications except for a transient embolic event without sequela (5%) and two cases (10%) of severe mitral regurgitation. The immediate success rate was 90%. The mean follow‐up was 70 ± 29 months (36–156 months). The 5‐year restenosis and intervention (repeat PMC or valve replacement) rates were 9.1 ± 5.2% and 3.6 ± 3.3%, respectively. The intervention free 5‐year survival in good functional capacity (New York Heart Association [NYHA] I–II) was 95.1 ± 5.5% and restenosis and intervention free 5‐year survival with good functional capacity was 89.7 ± 6.8%. Conclusions: Although from a limited number of selected patients, these findings indicate that repeat PMC is a safe and effective method, with follow‐up results similar to a first intervention and should be considered as the first therapeutic option in suitable patients.

A case of nodular posterior scleritis mimicking choroidal mass

The aim of this study is to report clinical and imaging findings, and treatment outcomes of a patient with nodular posterior scleritis. A 41-year-old woman was diagnosed as nodular posterior scleritis in the light of clinical and imaging findings. At first admission best corrected visual acuity was 20/50 in her right eye. Fundus examination revealed an amelanotic subretinal mass under the superior temporal arcade associated with subretinal fluid surrounding it. B-scan ultrasonography, optical coherence tomography, fluorescein angiography, and indocyanine green angiography findings confirmed the diagnosis. As treatment, nepafenac eye drops 3 times a day, and flurbiprofen tablet 100 mg twice a day were prescribed. After 4 weeks of treatment, the ocular pain was relieved, BCVA improved to 20/20, and subretinal mass totally regressed. Although the diagnosis of nodular posterior scleritis may be confusing, it has to be kept in mind in patients with a subretinal/choroidal mass. Multimodal fundus imaging may be helpful in differential diagnosis. The condition is usually curable with non-steroidal anti-inflammatory drugs and/or systemic steroids.     

The cognitive aspect of formal thought disorder and its relationship with global social functioning and the quality of life in schizophrenia

Purpose

It was expected that using a comprehensive scale like the Thought and Language Disorder Scale (TALD) for measurement of FTD would enable assessing its heterogeneity and its associations with cognitive impairment and functionality. This study has aimed to analyze the relationship between formal thought disorder (FTD) and cognitive functions, functionality, and quality of life in schizophrenia.

Methods

This cross-sectional exploratory study included 46 clinical participants meeting the DSM-5 diagnostic criteria for schizophrenia and 35 healthy individuals as the control groups. Data were acquired by means of the Turkish language version of the TALD, the Positive and Negative Syndrome Scale, the Clinical Global Impression Scale, the Functioning Assessment Short Test, the Social Functioning Scale, the World Health Organization Quality of Life Instrument-Short Form, and a neuropsychological test battery on executive functions, working memory, verbal fluency, abstract thinking, and response inhibition. Correlation analyses were conducted to detect significant relationships.

Results

The clinical group scored failures in all cognitive tests. The objective positive FTD was associated with deficits in executive functions and social functioning. The objective negative FTD was associated with poor performance in all cognitive domains, physical quality of life, and social and global functioning. The subjective negative FTD was negatively correlated with psychological quality of life.

Conclusion

This study demonstrated that objective FTD factors reflect different underlying cognitive deficits and correlate with different functioning domains. Significant correlation was determined between subjective negative FTD and psychological quality of life. Given the close relationship of FTD with functioning and quality of life, the FTD-related cognitive deficits should be the key treatment goal in schizophrenia.

     

Lamotrigine augmentation in patients with schizophrenia who show partial response to clozapine treatment

BackgroundSeveral placebo controlled studies investigating lamotrigine augmentation of clozapine in schizophrenia patients with partial response have shown varying results. The aim of this study was to further investigate the efficacy and safety of this augmentation strategy, and its effect on the glutamatergic system through utilizing mismatch negativity (MMN) component of auditory event related potentials.MethodsThe study was designed to evaluate the efficacy and safety of lamotrigine augmentation of clozapine in a 12-week, double-blind, placebo-controlled, prospective, randomized design. Thirty-four patients diagnosed according to DSM-IV schizophrenia criteria and with partial response to clozapine were included. Patients were randomized to 25 mg/day of lamotrigine or placebo, gradually increasing up to 200 mg/day on the 6th week. The change in psychopathology was assessed with Positive and Negative Syndrome (PANSS), Calgary Depression (CDS) and Clinical Global Impression-Severity (CGI-S) scales. A neuropsychological test battery was administered and MMN measurements were also obtained at baseline and endpoint. Safety evaluation included physical examination, UKU Side Effect Rating Scale (UKU) assessment and serum drug level measurements.ResultsNo significant differences were found between the two treatment groups in PANSS Positive and General Psychopathology, CDS, neurocognitive test and UKU scores, as well as MMN measurements. PANSS Total, Negative and CGI-S scores showed significant improvement compared to lamotrigine in the placebo group.ConclusionThis study did not show any benefit of augmentation of clozapine with lamotrigine in schizophrenia patients with partial response. The need for further investigation of other augmentation strategies of clozapine in partially responsive schizophrenia patients is evident.     

Right atrial ‘thrombus in transit’ and atrial septal defect in a 70-year-old man: cardioembolic source of pulmonary and paradoxical cerebral embolization

A 70-year-old man was admitted with sudden onset of dyspnea, near syncope and left hemiparesis. Clinical examination, blood gas analysis, ECG and the chest X-ray were consistent with pulmonary embolism. Transthoracic echocardiography (TTE) revealed right atrial free-floating thrombus, large atrial septal defect (ASD), right heart enlargement and pulmonary artery hypertension. Anticoagulation therapy was initiated immediately, soon after thrombolytic therapy was started but the patient died due to possible pulmonary or cerebral embolization. We underscore rapid diagnosis by TTE that revealed right heart thrombus in transit and large ASD.     

Cardiac metastasis of great saphenous vein leiomyosarcoma

We present a case with cardiac metastasis of the great saphenous vein leiomyosarcoma (LMS) that presented to the emergency department with dyspnea and palpitations 2 months ago. In this patient, hemodynamic instability was caused by an extensive right ventricular cavity and outflow tract invasion of the LMS. Treatment of the patient included incomplete mass resection, adjuvant chemotherapy, and permanent pacemaker implantation (due to postoperative complete atrio-ventricular block).     

The investigation of non‐invasive techniques for treating early approximal carious lesions: an in vivo study

Objectives: The aim of this study was to examine non‐cavitated approximal caries using non‐invasive treatment methods. Materials and methods : Molar and premolar teeth with approximal caries were used in this in vivo study. Approximal caries lesions were evaluated with visual and radiographic inspection and with the DIAGNOdent device. Five groups were formed to study non‐invasive treatment, and each had at least 25 early approximal carious lesions. Patients in the control group were not treated. After the separation, either ozone application, acidulated phosphate fluoride gel, CPP‐ACP‐containing material (Tooth Mousse), or an antibacterial bonding agent (Clearfil Protect Bond) was used. For 18 months after the non‐invasive treatment, radiological controls were used to observe the progress of the initial and approximal caries in the 1st, 3rd, 6th and 12th months of follow‐up. A Mann–Whitney U‐test was used to perform the statistical analysis; in‐group comparisons were made with the Wilcoxon signed‐rank test, and a quantitative assessment was performed using a chi‐squared test. Results: At the end of 18 months, the caries lesions in the control group were observed to progress (P < 0.01). The lesions that were scored as 1a during a visual inspection recovered by using non‐invasive treatments. Conclusion: Approximal caries lesions that were detected at the early stages remained stationary when using antibacterial agents and materials that promoted remineralisation. Clinical relevance: Antibacterial agents and remineralisation materials can be used in treatment of early approximal caries lesions.
