Extrinsic mechanism obstructing the opening of a prosthetic mitral valve: an unusual case of suture entrapment

Obstruction to a prosthetic cardiac valve is a well-recognized complication of cardiac valve replacement. Malfunction of the mobile component of a prosthetic valve to open or close correctly may occur in consequence of intrinsic or extrinsic causes (thrombus, vegetation, entrapment of left ventricular myocardium, suture entanglement, and pannus formation) that may result prosthetic valve stenosis and/or insufficiency. In the case we report a 48-year-old female with valve dysfunction occurred early after surgery, as one valve leaflet was only able to partially open due to suture entrapment.     

The Prevalence and Course of Pulmonary Hypertension and Right Ventricular Dysfunction in Patients Undergoing Orthotopic Heart Transplantation

BackgroundPulmonary hypertension (PHT) and right ventricular (RV) dysfunction are among the commonly observed and potentially serious complications following heart transplantation. RV dysfunction is reported to occur in as much as half of these patients. In this study, the authors sought to examine the prevalence and the course of these prognostically important complications.MethodsThe records of 30 patients who had undergone orthotopic heart transplantation at our center were examined. Demographic and clinical variables were noted; RV dysfunction, pulmonary artery pressure on Doppler echocardiographic examination, and catheter findings were recorded.ResultsThe mean age of the study population was 31.3 years. On preoperative assessment, PHT was present in 21 (70%) patients. The average value of systolic pulmonary artery pressure was 44.5 ± 5.9 mm Hg. The mean value of pulmonary vascular resistance was 3.3 ± 1.8 hybrid reference unit (HRU). RV dysfunction was detected on postoperative assessment in 17 (56.7%) patients. The mean ischemia time was 216 ± 77 minutes; in 3 cases it exceeded 5 hours but in none of the cases did it reach 6 hours. Rejection was detected in 14 (46.7%) patients. Most of the patients received inotropic agents in the early postoperative period. When compared with preoperative values, on follow up at the end of the first year, a significant decrease in pulmonary artery pressure was observed (47.4 ± 4.8 vs 38.5 ± 7.5 mm Hg; P = .03), and the ratio of patients experiencing RV dysfunction decreased to 16.6% (n = 5).ConclusionThe findings of this study indicate that RV dysfunction and PHT are common complications following heart transplantation and improve with appropriate management over time with monitoring.     

The incremental value of magnetic resonance imaging for breast surgery planning

Purpose

The aim of this study was to evaluate the effect of breast magnetic resonance imaging (MRI) on preoperative or intraoperative surgical planning.

Methods

One hundred and sixty females with breast cancer were enrolled in the study. The contribution of MRI compared to MMG and USG, their histopathological concordance, and their impact on surgical treatment were evaluated prospectively.

Results

In 48 (30.0%) of the patients, MRI identified suspicious lesions that were not detected by MMG and USG. The diagnosis by MRI was accurate in 17 (10.6%) of them, while in remaining 31 patients (19.4%) the additional lesions found by MRI and interpreted as malignant were found not to be malignant. The pathological accordance of MRI and MMG compared with USG were 69.3 and 70.0%, respectively, whereas individually, MMG and USG were in accordance with the pathological examination in 52.9 and 67.9% of the cases, respectively.

Conclusions

Assessment of the tumor size, multifocality, multicentricity, and presence of ductal carcinoma in situ by MRI may lead to misinterpretations in the majority of patients. The surgical approach should not be changed based solely on MRI findings. An accurately interpreted MMG combined with USG may be sufficient in most cases.     

An unresolved discussion: presence of premature ejaculation and erectile dysfunction in lumbar disc hernia

Purpose

Premature ejaculation (PE) and erectile dysfunction (ED) are both frequent diseases with several questions about the aetiological factors for these disorders. Lumbar disc herniation (LDH), which can cause both neurological and physiological impairments, may be a causative reason. We prospectively tried to evaluate the presence of PE and ED in patients with LDH and identify the effect of both surgical and physical therapy treatments for LDH on PE and ED.

Methods

A total of 50 patients with LDH and a corresponding control group without LDH at an age of 18–50 years were included in the study. Both PE and ED were evaluated with premature ejaculation diagnostic tool (PEDT) and International Index of Erectile Function. Mean intravaginal ejaculatory latency time (IELT) was calculated at their 5 consecutive intercourse. Physical therapy or microdiscectomy was performed according to indication. After 6 months of follow-up, patients in treatment group were re-evaluated for PE and ED.

Results

Mean age of study and control group was 34.1 ± 3.3 and 34.2 ± 4.0 years, respectively (p = 0.979). In LDH group, IELT was <1 min in 12 (24 %), 1–2 (16 %) min in 8, 2–3 min in 7 (14 %), 3–4 min in 7 (14 %) and 4 or more minutes in 16 (32 %) patients. These numbers were 11 (22 %), 8 (16 %), 5 (10 %), 9 (18 %) and 17 (34 %) in control group, respectively. Mean PEDT score of patients who had IELT < 1 min was 11.9 ± 2.1 and 10.7 ± 2.1 in study and control group, whereas it decreased to 1.0 ± 2.8 and 0.5 ± 1.8 as IELT increased over 4 min, respectively. There were 11 (22 %) patients with ED in LDH group, whereas there were only 2 (4 %) in control group (p = 0.017). Twenty patients with LDH underwent surgery while 30 had been taken into physical therapy. After 6 months, patients with PE significantly decreased in both surgery and physical therapy group (p = 0.025 and p = 0.046). Patients with ED also decreased after treatment, but the numbers were so limited for statistical evaluation.

Conclusion

Although ED was more frequent in patients with LDH, PE was similar in both study and control groups, but the treatment of LDH had positive effects on PE and ED.     

Avaliação de entesopatia em pacientes com fibromialgia por meio do novo índice ultrassonográfico de entesite

ObjectiveThe aim of the present study is to determine the frequency of enthesopathy in fibromyalgia (FM) by using a newly developed ultrasonography (US) method, the Madrid Sonography Enthesitis Index (MASEI).MethodsThis study was conducted on 38 consecutive patients with FM and 48 healthy sex- and age-matched controls. Six entheseal sites (olecranon tuberosity, superior and inferior poles of patella, tibial tuberosity, superior and inferior poles of calcaneus) on both lower limbs were evaluated. All US findings were identified according to MASEI. Scores of patients and controls were compared by Student's t-test and Mann-Whitney U-test. Validity was analysed by receiver operating characteristic curve. Values of P < 0.05 were considered significant.ResultsTotal enthesitis score was 7.39 ± 4.99 (mean ± SD) among FM patients and 3.7 ± 3.22 among healthy controls (P < 0.001). The receiver operating characteristic curve established an ultrasound score of > 3.5 in the FM group as the best cut-off point to differentiate between cases and controls. No statistically significant correlation was found between the MASEI score and the FM disease duration, and the location of the tender points.ConclusionsMisdiagnoses of FM are harmful to patients and the community, and the presence of enthesopathy among FM patients increases. Its detection with the MASEI score may help to discriminate FM patients presenting with ill-defined symptoms and signs, in order to prevent mistreatment.     

Is there a relationship between attention deficit/hyperactivity disorder and Osgood–Schlatter disease?

Purpose

The purpose of this prospective study is to investigate the relationship between Osgood–Schlatter disease (OSD) and attention deficit/hyperactivity disorder (ADHD).

Methods

Seventy-four children with a diagnosis of OSD were referred to child and adolescent psychiatry department for the evaluation of ADHD. Diagnostic and Statistical Manual of Mental Disorders was used for diagnostic criteria.

Results

Diagnosis of ADHD was made in 56 (75.6 %) out of 74 children.

Conclusions

Results of this study suggest that ADHD is a significant risk factor for OSD. During the evaluation of a patient with OSD, a thorough history should be obtained about the behavioral symptoms that indicate underlying ADHD. In case of suspicion, these patients should be referred for an additional evaluation by a child psychiatrist.
