Long-term effects of heart transplantation: the gap between physical performance and emotional well-being

The purpose of our study was to assess physical and emotional factors in heart transplant patients. A prospective design was used to compare patients' physical symptoms, emotional complaints, and restrictions at admission to the waiting list, immediately after, and 1 and 5 years after heart transplantation. Thirty-three patients were included (30 male, 3 female) in the study. Their mean age at admission was 48 +/- 10.2 years. Of these, 23 suffered from cardiomyopathy, 8 from coronary heart disease, and 2 from valvular insufficiency. At admission, the patients suffered from symptoms of cardiac insufficiency, and were restricted in sports, gardening, hobbies, sexual life, job, food-intake, and mobility. More than three-fourths rated their physical and emotional status as moderate to poor. Emotionally, they suffered from irritability, restlessness, depression, psychic lability, lowered drive, lack of social contact, low self-esteem, and anxiety. At the end of rehabilitation (4-8 weeks after the operation), all physical and emotional complaints, as well as restrictions had significantly decreased (p < 0.0001 to p < 0.001), except for trembling, numbness of hands/feet, and food-intake. One year postoperatively, patients reported even fewer physical complaints (p < 0.01). Three-fourths rated their physical and emotional status good or excellent. Five years postoperatively--in contrast to physical status, restrictions, and physical complaints--the emotional complaints had increased significantly (p < 0.0001). Patients reported excellent physical performance up to 5 years postoperatively. On the other hand, the study revealed that their emotional well-being had significantly deteriorated from 1 to 5 years postoperatively. Attention should, therefore, not only be paid to the good physical health of the survivors, but also to the worsening of their emotional status.

[Chronic anterior tibial syndrome]

In two young athletic men we made the diagnosis of chronic tibialis anterior syndrome. Pain during strenuous exercise was localized in the anterolateral aspect of both calves. After stopping exercise the complaints disappeared within 15-20 minutes and not in 2-3 minutes as it would be typical for patients with atherosclerotic peripheral arterial occlusive disease. Diagnosis is based on patient history, normal clinical examination (systolic ankle pressure determined by Doppler-Sonography, electronic segmental oscillography) and increased intramuscular pressure at rest (> 10 mmHg) and after exercise (42 and 35 mmHg). Bilateral fasciotomy was performed in both patients. They are free of pain after 3 respectively 6 months postoperatively.

Childhood extraordinary daytime urinary frequency-a case series and a systematic literature review

Childhood extraordinary daytime urinary frequency is likely a common but underreported condition characterized by daytime frequent voiding and typically not linked with complaints of burning, urinary incontinence, altered urinary stream, changes in the nighttime voiding pattern, excessive fluid intake and excessive urinary volume. To determine the features and outcome of extraordinary daytime urinary frequency, we report our experience with 14 children and the results of a formal systematic analysis of peer-reviewed English-language literature on this topic. Nineteen case series were found (together with 16 mostly pertinent comments), with each case series providing details on from one to 119 children. On the basis of our experience and the findings of our systematic analysis, we conclude that, in general practice, extraordinary daytime urinary frequency is a common cause of urinary frequency, that the age of such patients is, on average, 6 years and that the micturation abnormalities persist for an average of 6 months. The results of this review must be viewed with an understanding of the limitations of the analysis process, which incorporated data exclusively from case series.

Clinical presentation of celiac disease and the diagnostic accuracy of serologic markers in children

There has been growing recognition of a changing clinical presentation of celiac disease (CD), with the manifestation of milder symptoms. Serologic testing is widely used to screen patients with suspected CD and populations at risk. The aim of this retrospective analysis was to evaluate the clinical presentation of CD in childhood, assess the diagnostic value of serologic tests, and investigate the impact of IgA deficiency on diagnostic accuracy. We evaluated 206 consecutive children with suspected CD on the basis of clinical symptoms and positive serology results. Ninety-four (46%) had biopsy-proven CD. The median age at diagnosis of CD was 6.8 years; 15% of the children were <2 years of age. There was a higher incidence of CD in girls (p = 0.003). Iron deficiency and intestinal complaints were more frequent in children with CD than those without CD (61% vs. 33%, p = 0.0001 and 71% vs. 55%, p = 0.02, respectively), while failure to thrive was less common (35% vs. 53%, p = 0.02). The sensitivity of IgA tissue transglutaminase (IgA-tTG) was 0.98 when including all children and 1.00 after excluding children with selective IgA deficiency. The specificity of IgA-tTG was 0.73 using the recommended cut-off value of 20 IU, and this improved to 0.94 when using a higher cut-off value of 100 IU. All children with CD and relative IgA deficiency (IgA levels that are measurable but below the age reference [n = 8]) had elevated IgA-tTG. In conclusion, CD is frequently diagnosed in school-age children with relatively mild symptoms. The absence of intestinal symptoms does not preclude the diagnosis of CD; many children with CD do not report intestinal symptoms. While the sensitivity of IgA-tTG is excellent, its specificity is insufficient for the diagnostic confirmation of a disease requiring life-long dietary restrictions. Children with negative IgA-tTG and decreased but measurable IgA values are unlikely to have CD.

Astroblastoma in a child

BACKGROUND: Astroblastoma, an uncommon neuroepithelial tumor, typically presents in young adults as a well-circumscribed cortical or subcortical spherical mass. Astroblastoma may cause a diagnostic problem to anyone unfamiliar with its architectural and histological features. CASE HISTORY: We report the case of a 4-year-old boy who was referred for complaints of progressive deficits of balance and difficulty with walking during the previous 3 months. A large fronto-parietal cystic mass with solid mural nodule was discovered. Total removal of the tumor mass was performed, and a diagnosis of high grade (malignant) variant of astroblastoma was made. Postoperatively, the patient received radiation therapy, for a period of 11 weeks, followed by chemotherapy. He is in a good neurological recovery without any evidence of recurrence for 8 months. PROGNOSIS: The best treatment modality for astroblastoma is surgical resection if possible, whereas adjuvant therapy (radiotherapy and/or chemotherapy) can be considered in high-grade astroblastomas, with a close follow-up for all cases.

Neuromuscular issues in cavovarus foot

Differential muscle weakness can cause a cavus foot deformity. Presenting complaints in the hindfoot may include ankle instability, secondary arthritis, or peroneal tendonitis. Presenting complaints in the forefoot may include stress fractures, callus formation over the lateral border of the foot, claw toes, first ray overload, and metatarsalgia. More general presenting complaints can include a drop-foot gait, decreased walking tolerance, and difficulty with shoe or orthotic fitting. To surgically correct the foot shape, soft tissue contractures need to be released, bone deformity corrected, and muscles balanced to optimize their strength and prevent recurrence of the deformity. This article reviews the diagnosis and management of the cavovarus foot secondary to longstanding muscle imbalance.

The retina in Parkinson's disease

As a more complete picture of the clinical phenotype of Parkinson's disease emerges, non-motor symptoms have become increasingly studied. Prominent among these non-motor phenomena are mood disturbance, cognitive decline and dementia, sleep disorders, hyposmia and autonomic failure. In addition, visual symptoms are common, ranging from complaints of dry eyes and reading difficulties, through to perceptual disturbances (feelings of presence and passage) and complex visual hallucinations. Such visual symptoms are a considerable cause of morbidity in Parkinson's disease and, with respect to visual hallucinations, are an important predictor of cognitive decline as well as institutional care and mortality. Evidence exists of visual dysfunction at several levels of the visual pathway in Parkinson's disease. This includes psychophysical, electrophysiological and morphological evidence of disruption of retinal structure and function, in addition to disorders of ‘higher’ (cortical) visual processing. In this review, we will draw together work from animal and human studies in an attempt to provide an insight into how Parkinson's disease affects the retina and how these changes might contribute to the visual symptoms experienced by patients.

Effect of urinary tract infection on reservoir function in patients with ileal bladder substitute

PURPOSE: We determined the functional consequences of urinary tract infection in patients with an ileal bladder substitute in terms of urinary continence, post-void residual and urinary retention. MATERIALS AND METHODS: A total of 48 patients with culture documented urinary tract infection (single organism, 10(5) or greater cfu) were retrospectively evaluated before, during and after the infection for changes in continence, post-void residual and urinary retention as well as for resolution of symptomatology after appropriate antibiotic therapy. RESULTS: Of the 48 patients 40 had a single infection while the remaining 8 had multiple urinary tract infection episodes. During daytime 27 of the 44 patients with previously good daytime continence experienced deterioration in their baseline voiding status while infected. Of the 40 patients who were previously continent at night 20 had incontinence while infected. There were 15 patients with documented post-void residual and urinary retention developed in 4 during the urinary tract infection. All patients returned to baseline continence status and reservoir function after appropriate antibiotic treatment based on objective and subjective assessments. CONCLUSIONS: Urinary tract infection may cause urinary incontinence in patients with ileal bladder substitutes. Therefore, when there are complaints of de novo urinary incontinence, a finding of post-void residual or an acute presentation of urinary retention, a urinary tract infection should be excluded. When the urinary tract infection is appropriately treated urinary continence and reservoir function return to their baseline status.

Sleepiness and vigilance tests

Objective assessments of subjective complaints such as sleepiness, tiredness or fatigue using sleepiness and vigilance tests aim to identify its causes and to judge the fitness to drive or to work of the affected person. "Vigilance" comprises wakefulness, alertness and attention and is therefore not merely reciprocal to sleepiness. Since it is a complex phenomenon with several dimensions it is unlikely to be appropriately assessed by one single "vigilance test". One important dimension of vigilance discussed here is wakefulness with its counterpart of overt sleep and the whole spectrum of various levels in between. The transit zone between full wakefulness and overt sleep is mainly characterised by the subjective complaint of sleepiness, which cannot be measured directly. Only the consequences of reduced wakefulness such as a shortened sleep latency, slowed cognitive function and prolonged reaction time can be measured objectively. It is, therefore, more promising to combine a battery of subjective and objective tests to answer a specific question in order to achieve the most appropriate description for a given clinical or medicolegal situation. However even then we must keep in mind that many other important aspects of fitness to drive / fitness to work such as neurological, psychiatric and neuropsychological functions including risk taking behaviour are not covered by vigilance tests. A comprehensive, multidisciplinary approach is essential in such situations.

Cement-augmented anterior screw fixation of Type II odontoid fractures in elderly patients with osteoporosis

BACKGROUND CONTEXT: Closed reduction and internal fixation by an anterior approach is an established option for operative treatment of displaced Type II odontoid fractures. In elderly patients, however, inadequate screw purchase in osteoporotic bone can result in severe procedure-related complications. PURPOSE: To improve the stability of odontoid fracture screw fixation in the elderly using a new technique that includes injection of polymethylmethacrylat (PMMA) cement into the C2 body. STUDY DESIGN: Retrospective review of hospital and outpatient records as well as radiographs of elderly patients treated in a university hospital department of orthopedic surgery. PATIENT SAMPLE: Twenty-four elderly patients (8 males and 16 females; mean age, 81 years; range, 62-98 years) with Type II fractures of the dens. OUTCOME MEASURES: Complications, cement leakage (symptomatic/asymptomatic), operation time, loss of reduction, pseudarthrosis and revision surgery, patient complaints, return to normal activities, and signs of neurologic complications were all documented. METHODS: After closed reduction and anterior approach to the inferior border of C2, a guide wire is advanced to the tip of the odontoid under biplanar fluoroscopic control. Before the insertion of one cannulated, self-drilling, short thread screws, a 12 gauge Yamshidi cannula is inserted from anterior and 1 to 3 mL of high-viscosity PMMA cement is injected into the anteroinferior portion of the C2 body. During polymerization of the cement, the screws are further inserted using a lag-screw compression technique. The cervical spine then is immobilized with a soft collar for 8 weeks postoperatively. RESULTS: Anatomical reduction of the dens was achieved in all 24 patients. Mean operative time was 64 minutes (40-90 minutes). Early loss of reduction occurred in three patients, but revision surgery was indicated in only one patient 2 days after primary surgery. One patient died within the first eight postoperative weeks, one within 3 months after surgery. In five patients, asymptomatic cement leakage was observed (into the C1-C2 joint in three patients, into the fracture in two). Conventional radiologic follow-up at 2 and 6 months confirmed anatomical healing in 16 of the19 patients with complete follow-up. In two patients, the fractures healed in slight dorsal angulation; one patient developed a asymptomatic pseudarthrosis. All patients were able to resume their pretrauma level of activity. CONCLUSIONS: Cement augmentation of the screw in Type II odontoid fractures in elderly patients is technically feasible in a clinical setting with a low complication rate. This technique may improve screw purchase, especially in the osteoporotic C2 body.

Annexin A1 is a biomarker of T-tubular repair in skeletal muscle of nonmyopathic patients undergoing statin therapy

Skeletal muscle complaints are a common consequence of cholesterol-lowering therapy. Transverse tubular (T-tubular) vacuolations occur in patients having statin-associated myopathy and, to a lesser extent, in statin-treated patients without myopathy. We have investigated quantitative changes in T-tubular morphology and looked for early indicators of T-tubular membrane repair in skeletal muscle biopsy samples from patients receiving cholesterol-lowering therapy who do not have myopathic side effects. Gene expression and protein levels of incipient membrane repair proteins were monitored in patients who tolerated statin treatment without myopathy and in statin-naive subjects. In addition, morphometry of the T-tubular system was performed. Only the gene expression for annexin A1 was up-regulated, whereas the expression of other repair genes remained unchanged. However, annexin A1 and dysferlin protein levels were significantly increased. In statin-treated patients, the volume fraction of the T-tubular system was significantly increased, but the volume fraction of the sarcoplasmic reticulum remained unchanged. A complex surface structure in combination with high mechanical loads makes skeletal muscle plasma membranes susceptible to injury. Ca(2+)-dependent membrane repair proteins such as dysferlin and annexin A1 are deployed at T-tubular sites. The up-regulation of annexin A1 gene expression and protein points to this protein as a biomarker for T-tubular repair.

Perception of atrial fibrillation before and after radiofrequency catheter ablation: relevance of asymptomatic arrhythmia recurrence.

BACKGROUND The objective of this study was to assess the incidence and impact of asymptomatic arrhythmia in patients with highly symptomatic atrial fibrillation (AF) who qualified for radiofrequency (RF) catheter ablation. METHODS AND RESULTS In this prospective study, 114 patients with at least 3 documented AF episodes together with corresponding symptoms and an ineffective trial of at least 1 antiarrhythmic drug were selected for RF ablation. With the use of CARTO, circumferential lesions around the pulmonary veins and linear lesions at the roof of the left atrium and along the left atrial isthmus were placed. A continuous, 7-day, Holter session was recorded before ablation, right after ablation, and after 3, 6, and 12 months of follow-up. During each 7-day Holter monitoring, the patients recorded quality and duration of any complaints by using a detailed symptom log. More than 70,000 hours of ECG recording were analyzed. In the 7-day Holter records before ablation, 92 of 114 patients (81%) had documented AF episodes. All episodes were symptomatic in 35 patients (38%). In 52 patients (57%), both symptomatic and asymptomatic episodes were recorded, whereas in 5 patients (5%), all documented AF episodes were asymptomatic. After ablation, the percentage of patients with only asymptomatic AF recurrences increased to 37% (P<0.05) at the 6-month follow-up. An analysis of patient characteristics and arrhythmia patterns failed to identify a specific subset who were at high risk for the development of asymptomatic AF. CONCLUSIONS Even in patients presenting with highly symptomatic AF, asymptomatic episodes may occur and significantly increase after catheter ablation. A symptom-only-based follow-up would substantially overestimate the success rate. Objective measures such as long-term Holter monitoring are needed to identify asymptomatic AF recurrences after ablation.

Actions speak louder than words

Ethical scandals in business have led to calls for more ethical or moral leadership. Yet, we still know very little about what characterizes ethical leadership and what its positive consequences actually are. We argue that the major question is not about what leaders value, but rather whether their ethical values are regularly reflected in behavioral patterns across situations and situational challenges. To address this, we have begun to build the Ethical Leadership Behavior Scale, which is based on behaviors reflecting concrete manifestations of ethical values (e.g., fairness, respect) across occasions and situational barriers. A study with 592 employees of 110 work units in two departments provided a first test of this scale and demonstrated that the level of ethical leadership behavior predicts important work-related attitudes (job satisfaction, work engagement, affective organizational commitment) and outcomes (health complaints, emotional exhaustion, absenteeism).

Ultrasound of the axillary arch muscle in children

Purpose: Unilateral or bilateral axillary masses in children are often of clinical concern for malignancies. Our review illustrates a normal variant of the axilla mimicking clinically an axillary mass. Methods and Materials: Systematic review of our PACS and RIS with the keyword “axilla” and the modality “ultrasound” in children under 16 years of age from 1.12.2009 until 30.11.2012. 19 axillary ultrasound examinations in 16 patients (7m/9f, age 3 months to 15 years) were included. One patient was examined 2 and one patient 3 times. In 6 patients a prominent muscle was noted overlying the humeral head in an abducted position. The muscle diameter was measured in cm and compared with the contralateral side. In one patient photographs of the axilla were available. Results: In 16 examinations a lymphadenopathy (n=5), abscess formation (n=5), seroma or hematoma (n=1) or lymphangioma (n=1) and no diagnosis (n=1) was found. In 4 patients (25%) a unilateral muscle variant and in 2 patients a bilateral muscle variant (axillary arch muscle) was noted. In one patient a duplication of the muscle was found. In 4 patients the muscle was larger than the contralateral side. Conclusion: An axillary mass in children without other clinical complaints may be related to a normal variant, the axillary arch muscle. Ultrasound is the first modality of choice if imaging is required. Radiologists should be aware of this normal variant since no other workup is necessary in asymptomatic children.

High frequency repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral cortex: EEG topography during waking and subsequent sleep.

Repetitive transcranial magnetic stimulation (rTMS) is a novel research tool in neurology and psychiatry. It is currently being evaluated as a conceivable alternative to electroconvulsive therapy for the treatment of mood disorders. Eight healthy young (age range 21-25 years) right-handed men without sleep complaints participated in the study. Two sessions at a 1-week interval, each consisting of an adaptation night (sham stimulation) and an experimental night (rTMS in the left dorsolateral prefrontal cortex or sham stimulation; crossover design), were scheduled. In each subject, 40 trains of 2-s duration of rTMS (inter-train interval 28 s) were applied at a frequency of 20 Hz (i.e. 1600 pulses per session) and at an intensity of 90% of the motor threshold. Stimulations were scheduled 80 min before lights off. The waking EEG was recorded for 10-min intervals approximately 30 min prior to and after the 20-min stimulations, and polysomnographic recordings were obtained during the subsequent sleep episode (23.00-07.00 h). The power spectra of two referential derivations, as well as of bipolar derivations along the antero-posterior axis over the left and right hemispheres, were analyzed. rTMS induced a small reduction of sleep stage 1 (in min and percentage of total sleep time) over the whole night and a small enhancement of sleep stage 4 during the first non-REM sleep episode. Other sleep variables were not affected. rTMS of the left dorsolateral cortex did not alter the topography of EEG power spectra in waking following stimulation, in the all-night sleep EEG, or during the first non-REM sleep episode. Our results indicate that a single session of rTMS using parameters like those used in depression treatment protocols has no detectable side effects with respect to sleep in young healthy males.
