Gender-related differences in octogenarians with congenital coronary artery fistula: a report of two cases and a review

Aim

To highlight gender-related differences in octogenarians with a congenital coronary artery fistula (CAF).

Materials and methods

We present two elderly female patients with a congenital fistula, a septuagenarian and a nonagenarian, and review the world literature between 1954–2010.

Results

The septuagenarian patient presented with easy fatigability and the nonagenarian patient with acute myocardial infarction contralaterally to the fistula. Coronary angiography (CAG) demonstrated a coronary-pulmonary artery fistula (CPF). The nonagenarian patient underwent percutaneous coronary intervention of the right coronary artery. CAG revealed a CPF associated with a huge multiple aneurysmal formation. Data from 57 mainly symptomatic patients with a mean age of 75.3 years (range 70–87 years) were collected. The cohort was subdivided into female (mean age 84.3 years) and male (mean age 75.2 years) subgroups and compared with each other. Multi-origin (bilateral and multilateral) was prevalent in females, 40% versus 12% in males. Aneurysmal formation was found in females and males in 40% and 18%, respectively. Ethnicity was 65% Caucasian and 35% Asian. Multi-origin fistulas were prevalent in the Asian (45%) compared with the Caucasian (11%) subset.

Conclusions

A septuagenarian and a nonagenarian female patient with congenital CAF are presented. On reviewing the literature, important differences were found between elderly females and males with congenital CAF.     

A huge intraductal papillary mucinous carcinoma of the bile duct treated by right trisectionectomy with caudate lobectomy

Background

Leiomyomas of esophagus, although rare, are the most frequent benign tumors of esophagus. Aim of this study is the presentation of 7 patients with esophageal leiomyomas who underwent surgical treatment during a 9-year period.

Methods

Epidemiological data (sex, age), the presenting symptoms, diagnostic examinations, tumor location, histopathological findings and the safety and efficacy of surgical resection are analyzed and assessed.

Results

5 men and 2 women with mean age of 56.9 years were operated. In 3 cases the tumor was located at the lower esophagus, while in the other 4 cases, the leiomyoma was found at the median third of esophagus. 4 patients had severe symptoms related to the leiomyoma, such as dysphagia and epigastric pain. All patients underwent a right postolateral thoracotomy with enucleation of the lesion. None of them received resection of part of the esophagus. The mean diameter of the resected tumors was 4.3 cm. The dimensions of leiomyomas were immediately associated with the symptoms. In no case was detected malignancy or recurrence. All patients were relieved from their symptoms, while postoperative morbidity and mortality did not occur.

Conclusions

Esophageal leiomyoma is a benign tumor, which causes symptoms only if its size becomes large. Surgical enucleation is considered to be safe and effective, without complications.     

Les fistules péniennes urétrocutanées postcirconcision: à propos de 85 cas

Purpose

To assess clinical and therapeutic aspects of penile urethral fistula following circumcision in our daily urological practice.

Patients and methods

We carried out a retrospective study of cases of penile fistula between 1990 and 2007.

Results

A series of 85 cases is reported. The mean age was 10.7 years (15 months-38 months). The circumcision was performed by paramedical persons in the majority of cases. The mean period elapsing before consultation was 4.1 ± 5.3 years (range: 1 week-28 years). The fistula was associated with partial amputation of the glans penis in one case, and with urethral meatus stenosis in three cases. The surgical treatment was layered repair in the majority of cases. The average follow-up was 3.35 years (range: 2 months-8 years). Overall results were satisfactory in 81.2% of cases.

Conclusions

Penile fistula due to circumcision is common in our region. Its management is codified but there is a significant risk of failure, making prevention even more important.     

Monophasic synovial sarcoma presenting as a primary ileal mass: a case report and review of the literature

Introduction

Iliocaval fistulas can complicate an iliac artery aneurysm. The clinical presentation is classically a triad of hypotension, a pulsatile mass and heart failure. In this instance, following presentation with multiorgan failure, management included the immediate use of an endovascular stent graft on discovery of the fistula.

Case presentation

A 62-year-old Caucasian man presented to our tertiary hospital for management of iatrogenic trauma due to the insertion of a central venous line into his right common carotid artery, causing transient ischemic attack. Our patient presented to a peripheral hospital with fever, nausea, vomiting, acute renal failure, acute hepatic dysfunction and congestive heart failure. A provisional diagnosis of sepsis of unknown origin was made. There was a 6.5 cm×6.5 cm right iliac artery aneurysm present on a non-contrast computed tomography scan. An unexpected intra-operative diagnosis of an iliocaval fistula was made following the successful angiographic removal of the central line to his right common carotid artery. Closure of the iliocaval fistula and repair of the iliac aneurysm using a three-piece endovascular aortic stent graft was then undertaken as part of the same procedure. This was an unexpected presentation of an iliocaval fistula.

Conclusion

Our case demonstrates that endovascular repair of a large iliac artery aneurysm associated with a caval fistula is safe and effective and can be performed at the time of the diagnostic angiography. The presentation of an iliocaval fistula in this case was unusual which made the diagnosis difficult and unexpected at the time of surgery. The benefit of immediate repair, despite hemodynamic instability during anesthesia, is clear. Our patient had two coronary angiograms through his right femoral artery decades ago. Unusual iatrogenic causes of iliocaval fistulas secondary to previous coronary angiograms with wire and/or catheter manipulation should be considered in patients such as ours.     

Diagnostic and therapeutic approach of congenital solitary coronary artery fistulas in adults: Dutch case series and review of literature

Background

Coronary artery fistulas (CAFs) are infrequent anomalies, coincidentally detected during coronary angiography (CAG).

Aim

To elucidate the currently used diagnostic imaging modalities and applied therapeutic approaches.

Materials and Methods

Five Dutch patients were found to have CAFs. A total of 170 reviewed subjects were subdivided into two comparable groups of 85 each, treated with either percutaneous ‘therapeutic’ embolisation (PTE group) or surgical ligation (SL group).

Results

In our series, the fistulas were visualised with several diagnostic imaging tests using echocardiography, multidetector computed tomography, and CAG. Four fistulas were unilateral and one was bilateral; five originated from the left and one originated from the right coronary artery. Among the reviewed subjects, high success rates were found in both treatment groups (SL: 97% and PTE: 93%). Associated congenital or acquired cardiovascular disorders were frequently present in the SL group (23%). Bilateral fistulas were present in 11% of the SL group versus 1% of the PTE group. The fistula was ligated surgically in one and abolished percutaneously in another. Medical treatment including metoprolol was conducted in two, and watchful waiting follow-up was performed in one.

Conclusions

Several diagnostic imaging techniques are available for assessment of the anatomical and functional characteristics of CAFs.     

Fibroma with minor sex cord elements – an incidental finding in a normal sized ovary A case report with literature review

Background

Glomerulocystic kidney disease is an uncommon type of cystic renal disease. It is characterized by cortical microsysts, which are represented by cystic dilatation of Bowman's spaces.

Case presentation

We describe a case of glomerulocystic disease in a neonate and another in an abortus associated with tracheo-oesophageal fistula and megacystic-megaureter syndrome. The kidney on autopsy was sponge-like and revealed presence of cysts corresponding to dilatations of Bowman's space microscopically. In these two cases, the Glomerulocystic Kidney Disease in one case corresponded to a sporadic form and, in the other, to a syndromic, non-heritable form of glomerulocystic kidney disease.

Conclusion

The associated anomalies in Glomerulocystic Kidney disease are well described in the literature. Two more new unrelated associations are described in this article.     

Airway sizes and proportions in children quantified by a video-bronchoscopic technique

Background

Detecting serum antibody against inhaled antigens is an important diagnostic adjunct for hypersensitivity pneumonitis (HP). We sought to validate a quantitative fluorimetric assay testing serum from bird fanciers.

Methods

Antibody activity was assessed in bird fanciers and control subjects using various avian antigens and serological methods, and the titer was compared with symptoms of HP.

Results

IgG antibody against pigeon serum antigens, quantified by fluorimetry, provided a good discriminator of disease. Levels below 10 mg/L were insignificant, and increasing titers were associated with disease. The assay was unaffected by total IgG, autoantibodies and antibody to dietary hen's egg antigens. Antigens from pigeon serum seem sufficient to recognize immune sensitivity to most common pet avian species. Decreasing antibody titers confirmed antigen avoidance.

Conclusion

Increasing antibody titer reflected the likelihood of HP, and decreasing titers confirmed antigen avoidance. Quantifying antibody was rapid and the increased sensitivity will improve the rate of false-negative reporting and obviate the need for invasive diagnostic procedures. Automated fluorimetry provides a method for the international standardization of HP serology thereby improving quality control and improving its suitability as a diagnostic adjunct.     

Three-dimensional computed tomography overlay for pulmonary vein antrum isolation: Follow-up and clinical outcomes

Background

To facilitate the creation of circumferential lines in pulmonary vein (PV) antrum isolation, three-dimensional (3D) navigation systems are used widely. Alternatively, 3D reconstructions of the left atrium (LA) can be superimposed directly on fluoroscopy to guide ablation catheters and to mark ablation sites.

Methods

In 71 atrial fibrillation patients circumferential PV ablation was performed. 3D reconstructions of the LA were derived from contrast cardiac-computed tomography and circumferential PV isolation was performed. In subsequent ablation procedures, veins were re-isolated, and defragmentation or linear lesions were performed if necessary.

Results

Adequate 3D reconstructions were formed and registered to fluoroscopy in all patients. All veins, except 2 in one single patient, could be isolated, resulting in freedom of AF in 45 patients (63?%). In 19 patients a second procedure was performed, in which 2.7?±?1.1 PV per patient were re-isolated; in 3 patients a third procedure was performed. After follow-up of 15?±?8?months, 51 (91?%) of patients with paroxysmal and 10 (67?%) with persistent AF were free of AF.

Conclusions

The results of 3D overlay for circumferential PV isolation are good, although the reconduction rate and need for subsequent ablations remains high, and the outcomes of this technique appear to be equivalent to other mapping techniques.     

Painful rib hump: a new clinical sign for detecting intraspinal rib displacement in scoliosis due to neurofibromatosis

Background

Spinal cord compression and associate neurological impairment is rare in patients with scoliosis and neurofibromatosis. Common reasons are vertebral subluxation, dislocation, angulation and tumorous lesions around the spinal canal. Only twelve cases of intraspinal rib dislocation have been reported in the literature. The aim of this report is to present a case of rib penetration through neural foramen at the apex of a scoliotic curve in neurofibromatosis and to introduce a new clinical sign for its detection.

Methods

A 13-year-old girl was evaluated for progressive left thoracic kyphoscoliotic curve due to a type I neurofibromatosis. Clinical examination revealed multiple large thoracic and abdominal "cafe-au-lait" spots, neurological impairment of the lower limbs and the presence of a thoracic gibbous that was painful to pressure at the level of the left eighth rib (Painful Rib Hump). CT-scan showed detachment and translocation of the cephalic end of the left eighth rib into the adjacent enlarged neural foramen. The M.R.I. examination of the spine showed neither cord abnormality nor neurogenic tumor.

Results

The patient underwent resection of the intraspinal mobile eighth rib head and posterior spinal instrumentation and was neurologically fully recovered six months postoperatively.

Conclusion

Spine surgeons should be aware of intraspinal rib displacement in scoliotic curves in neurofibromatosis. Painful rib hump is a valuable diagnostic tool for this rare clinical entity.     

Usability evaluation of a clinical decision support tool for osteoporosis disease management

Background

There is an extensive body of literature on health system quality reporting that has yet to be characterized. Scoping is a novel methodology for systematically assessing the breadth of a body of literature in a particular research area. Our objectives were to showcase the scoping review methodology in the review of health system quality reporting, and to report on the extent of the literature in this area.

Methods

A scoping review was performed based on the York methodology outlined by Arksey and O'Malley from the University of York, United Kingdom. We searched 14 peer reviewed and grey literature databases limiting the search to English language and non-English language articles with English abstracts published between 1980 and June 2006 with an update to November 2008. We also searched specific websites, reference lists, and key journals for relevant material and solicited input from key stakeholders. Inclusion/exclusion criteria were applied to select relevant material and qualitative information was charted from the selected literature.

Results

A total of 10,102 articles were identified from searching the literature databases, 821 were deemed relevant to our scoping review. An additional 401 were identified from updates, website searching, references lists, key journals, and stakeholder suggestions for a total of 1,222 included articles. These were categorized and catalogued according to the inclusion criteria, and further subcategories were identified through the charting process. Topic areas represented by this review included the effectiveness of health system report cards (n = 194 articles), methodological issues in their development (n = 815 articles), stakeholder views on report cards (n = 144 articles), and ethical considerations around their development (n = 69 articles).

Conclusions

The scoping review methodology has permitted us to characterize and catalogue the extensive body of literature pertaining to health system report cards. The resulting literature repository that our review has created can be of use to researchers and health system stakeholders interested in the topic of health system quality measurement and reporting.     

Aspects diagnostiques et thérapeutiques de la torsion du cordon spermatique au CHU Aristide-Le-Dantec de Dakar

Objective

To study the diagnostic and therapeutic features of testicular torsion in our daily practice, and to compare our results with that of the existing literature.

Patients and methods

A retrospective study was conducted from January 2002 to December 2009 on all patients who presented in emergency with suspicion of testicular torsion.

Results

Testicular torsion was confirmed in 58 patients after scrotal exploration. The average age was 20 years (range, 1–44 years), and 48 patients (83%) were more than 15 years old. The average duration from time of onset of pain to arrival at the emergency department was 102 hours; 47 patients (81%) were received after the sixth hour and 19 (33%) were referred from peripheral health facilities. Torsion was supravaginal in 5 patients, all more than 15 years old; orchidectomy was performed in 30 patients (52%).

Conclusion

In our study, we have a high proportion of orchidectomy. To reduce this, it will be important to sensibilize population to go to the hospital when they have cases of testicular pain and edema.     

Priapisme aigu drépanocytaire: analyse de 20 cas traités au CHU de Brazzaville

Objective

To evaluate the results of medical and surgical treatment of sickle cell priapism.

Patients and methods

Between 01 January, 1995 and 31 December, 2005, 20 patients were treated for priapism in the services of Urology-Andrology and Haematology of the University Hospital, Brazzaville. Treatment included intracavernous injection of etilefrine and cavernospongious fistula.

Results

1) Five patients initially treated with transfusion and oral etilefrine without success were successfully cured after using the technique of Winter. 2) In 5 patients treated with intracavernous injection of etilefrine as first-line, 3 were cured and two failed, who were later cured using the technique of Winter. 3) Of 10 patients treated by Winter cavernospongious fistulas as first-line, 3 had recurrences and secondarily were successfully treated by the method of Al-Ghorab. Functional results in the long term include 25% lack of erection, 25% of erection failure and 50% of normal erection.

Conclusion

Treatment with intracavernous injection of etilefrine is effective before the 24th hour. Beyond this time, cavernospongious fistula yield better results.     

Model-based optimal PEEP in mechanically ventilated ARDS patients in the Intensive Care Unit

Background

Swallowing accelerometry has been suggested as a potential non-invasive tool for bedside dysphagia screening. Various vibratory signal features and complementary measurement modalities have been put forth in the literature for the potential discrimination between safe and unsafe swallowing. To date, automatic classification of swallowing accelerometry has exclusively involved a single-axis of vibration although a second axis is known to contain additional information about the nature of the swallow. Furthermore, the only published attempt at automatic classification in adult patients has been based on a small sample of swallowing vibrations.

Methods

In this paper, a large corpus of dual-axis accelerometric signals were collected from 30 older adults (aged 65.47 ± 13.4 years, 15 male) referred to videofluoroscopic examination on the suspicion of dysphagia. We invoked a reputation-based classifier combination to automatically categorize the dual-axis accelerometric signals into safe and unsafe swallows, as labeled via videofluoroscopic review. From these participants, a total of 224 swallowing samples were obtained, 164 of which were labeled as unsafe swallows (swallows where the bolus entered the airway) and 60 as safe swallows. Three separate support vector machine (SVM) classifiers and eight different features were selected for classification.

Results

With selected time, frequency and information theoretic features, the reputation-based algorithm distinguished between safe and unsafe swallowing with promising accuracy (80.48 ± 5.0%), high sensitivity (97.1 ± 2%) and modest specificity (64 ± 8.8%). Interpretation of the most discriminatory features revealed that in general, unsafe swallows had lower mean vibration amplitude and faster autocorrelation decay, suggestive of decreased hyoid excursion and compromised coordination, respectively. Further, owing to its performance-based weighting of component classifiers, the static reputation-based algorithm outperformed the democratic majority voting algorithm on this clinical data set.

Conclusion

Given its computational efficiency and high sensitivity, reputation-based classification of dual-axis accelerometry ought to be considered in future developments of a point-of-care swallow assessment where clinical informatics are desired.     

Localized early mesenteric Castleman's disease presenting as recurrent intestinal obstruction: a case report

Introduction

Pleomorphic adenoma is the most common benign neoplasm of the salivary glands. Extensive lipomatous involvement of the tumor is, however, a very rare finding.

Case report

Herein, a rare case of lipomatous pleomorphic adenoma arising in the parotid gland of a 14-year-old Japanese woman is presented.

Conclusion

This is the sixth case of lipomatous pleomorphic adenoma in the English literature. Recognition of this rare subtype of pleomorphic adenoma is important for clinical diagnosis and management. On CT scan, it may not be detected possibly due to the extensive fatty component.     

Les prothèses gonflables dans le traitement de l'impuissance: résultats de 80 implantations

Objective

The goal of this study is the evaluation of the functionnal results and the complications of this type of surgery. Such questions have been poorly discussed in the literature.

Methods

We report our experience on 80 inflatable prostheses that were implanted between october 1987 and october 1994. The mean follow-up is 3 years and the assessment of the objective (mechanical functioning of the prosthesis and complications) and sujective results (sexuality of the patients) is carried out on 68 patients.

Results

The results are the following:

? 54.5% of functioning disturbances,

? 7% of infections,

? 27.5% of prosthesis removals.

Most of the patients considered they were satisfied although only 65% returned to a regular sexual activity.     

"Pseudosarcoma" in a pregnant woman

Background

As a result of improvements in diagnostic accuracy, the primary source of the tumour is identified in more than 99% of cases presenting with a malignancy. Whilst the axial skeleton is a common site of metastases, the sternum is rarely affected, especially by isolated metastases.

Case presentation

We report a case of a 68 year old male who was referred to the surgical outpatient clinic with a six month history of sternal pain. The patient was known to have essential thrombocythaemia, which had recently transformed into acute myeloid leukaemia but a sternal biospy showed mucinous adenocarcinoma. He had not localising symptoms and full evaluation failed to localise the primary tumour.

Conclusion

Solitary sternal metastases are rare and when found an underlying neoplasm is usually identified allowing targeted treatment. If however, there is no symptomatic tumour, the metastasis should simply be treated symptomatically.     

Managing potato wart: a review of present research status and future perspective

Key message

Identification of resistance genes to potato wart disease caused by Synchytrium endobioticum is the key for developing diagnostic markers for breeding resistant cultivars. We present an overview on the current knowledge of this host-pathogen system and molecular advances while highlighting future research focus.

Abstract

Potato wart is a quarantined disease of cultivated potato (Solanum tuberosum L.) caused by the obligate biotrophic, soil-borne fungus Synchytrium endobioticum (Schilb.) Perc. Since its discovery by Schilberszky in 1896, the management of wart disease was enabled by research efforts focusing on understanding and classifying the causative agent, its mode of infection, pathogenesis, geographical distribution, detection and chemical control, on developing screening methods for host resistance and on genetic analyses, which led to the development of resistant cultivars. These early successes are currently challenged by new S. endobioticum pathotypes evolving and the increased risk of dissemination by potato tuber trade. New research efforts are therefore required to ensure continuation of effective and sustainable management of the potato wart disease. Advances in molecular biology and genomic tools offer potential for innovations. This review presents an overview on what we know about this complex host-pathogen interaction, highlights recent molecular work and embarks on an outlook towards future research directions.     

Low back pain during pregnancy caused by a sacral stress fracture: a case report

Introduction

Sublingual hematoma secondary to excessive anticoagulation is a rare but potentially fatal condition, and few cases have been documented in the literature.

Case presentation

We report the case of a 73-year-old Caucasian woman who attended our Accident and Emergency department with massive sublingual hematoma causing superior displacement of the tongue. The condition was found to be the result of an elevated international normalized ratio, further complicated by a traumatic mandibular denture.

Conclusions

In summary, we recommend the immediate reversal of anticoagulation therapy on admission of patients with severe sublingual hematoma. We further advise surgical decompression/drainage if required and to continue meticulous monitoring. In all cases of early recognition of sublingual hematoma, prompt medical treatment and continuous clinical monitoring is essential, and may prevent the need for a surgical airway procedure.     

Fibromatoses desmoïdes: étude immunohistochimique de 14 cas sur tissue microarray (TMA)

Background/aim

Desmoid fibromatosis are rare, benign but locally aggressive tumors, characterized by an infiltrative growth and a tendency towards local recurrence, but an inability to metastasise. The morphological diagnosis may be difficult, requiring immunohistochemistry. The aim of our study is to determine the im munohistochemical phenotypes of these tumours to evaluate if they are helpful and to define a diagnostic strategy.

Methods

Immunohistochemistry was used to examine the expression of β-catenin, APC protein, in archival material derived from fourteen cases of extraabdominal desmoid tumors. Desmoids specimens were assembled into a clinical data-linked tissue micro — array. Nuclear β-catenin expression was observed in 100% of the specimens. Positive cytoplasmic staining for APC protein was found in 11 of 14 (78,6%). But all samples were negative for oestrogen and progesterone receptors, c-KIT and WT1.

Results

Our results regarding β-catenin and APC confirm the previous findings that those proteins play a crucial role in the pathogenesis of sporadic aggressive fibromatosis.     

Algorithms for the diagnosis and treatment of restless legs syndrome in primary care

Background

Restless legs syndrome (RLS) is a neurological disorder with a lifetime prevalence of 3-10%. in European studies. However, the diagnosis of RLS in primary care remains low and mistreatment is common.

Methods

The current article reports on the considerations of RLS diagnosis and management that were made during a European Restless Legs Syndrome Study Group (EURLSSG)-sponsored task force consisting of experts and primary care practioners. The task force sought to develop a better understanding of barriers to diagnosis in primary care practice and overcome these barriers with diagnostic and treatment algorithms.

Results

The barriers to diagnosis identified by the task force include the presentation of symptoms, the language used to describe them, the actual term "restless legs syndrome" and difficulties in the differential diagnosis of RLS.

Conclusion

The EURLSSG task force reached a consensus and agreed on the diagnostic and treatment algorithms published here.
