Binocular versus standard occlusion or blurring treatment for unilateral amblyopia in children aged three to eight years.

BACKGROUND: Current treatments for amblyopia, typically patching or pharmacological blurring, have limited success. Less than two-thirds of children achieve good acuity of 0.20 logMAR in the amblyopic eye, with limited improvement of stereopsis, and poor adherence to treatment. A new approach, based on presentation of movies or computer games separately to each eye, may yield better results and improve adherence. These treatments aim to balance the input of visual information from each eye to the brain.  OBJECTIVES: To determine whether binocular treatments in children, aged three to eight years, with unilateral amblyopia result in better visual outcomes than conventional patching or pharmacological blurring treatment. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register), MEDLINE, Embase, ISRCTN, ClinicalTrials.gov, and the WHO ICTRP to 19 November 2020, with no language restrictions. SELECTION CRITERIA: Two review authors independently screened the results of the search for relevant studies. We included randomised controlled trials (RCTs) that enrolled children between the ages of three and eight years old with unilateral amblyopia. Amblyopia was classed as present when the best-corrected visual acuity (BCVA) was worse than 0.200 logMAR in the amblyopic eye, with BCVA 0.200 logMAR or better in the fellow eye, in the presence of an amblyogenic risk factor, such as anisometropia, strabismus, or both. To be eligible, children needed to have undergone cycloplegic refraction and  ophthalmic examination, including fundal examination and optical treatment, if indicated, with stable BCVA in the amblyopic eye despite good adherence with wearing glasses. We included any type of binocular viewing intervention, on any device (e.g. computer monitors viewed with liquid-crystal display shutter glasses; hand-held screens, including mobile phones with lenticular prism overlay; or virtual reality displays). Control groups received standard amblyopia treatment, which could include patching or pharmacological blurring of the better-seeing eye. We included full-time (all waking hours) and part-time (between 1 and 12 hours a day) patching regimens. We excluded children who had received any treatment other than optical treatment; and studies with less than 8-week follow-up. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. The primary outcome of the review was the change from baseline of distance BCVA in the amblyopic eye after 16 (± 2) weeks of treatment, measured in logMAR units on an age-appropriate acuity test. MAIN RESULTS: We identified one eligible RCT of conventional patching treatment versus novel binocular treatment, and analysed a subset of 68 children who fulfilled the age criterion of this review. We obtained data for the mean change in amblyopic eye visual acuity, adverse events (diplopia), and adherence to prescribed treatment at 8- and 16-week follow-up intervals, though no data were available for change in BCVA after 52 weeks. Risk of bias for the included study was considered to be low. The certainty of evidence for the visual acuity outcomes at 8 and 16 weeks of treatment and adherence to the study intervention was rated moderate using the GRADE criteria, downgrading by one level due to imprecision. The certainty of evidence was downgraded by two levels and rated low for the proportion of participants reporting adverse events due to the sample size.  Acuity improved in the amblyopic eye in both the binocular and patching groups following 16 weeks of treatment (improvement of -0.21 logMAR in the binocular group and -0.24 logMAR in the patching group, mean difference (MD) 0.03 logMAR (95% confidence interval (CI) -0.10 to 0.04; 63 children). This difference was non-significant and the improvements in both the binocular and patching groups are also considered clinically similar. Following 8 weeks of treatment, acuity improved in both the binocular and patching groups (improvement of -0.18 logMAR in the patching group compared to -0.16 logMAR improvement in the binocular-treatment group) (MD 0.02, 95% CI -0.04 to 0.08). Again this difference was statistically non-significant, and the differences observed between the patching and binocular groups are also clinically non-significant. No adverse event of permanent diplopia was reported. Adherence was higher in the patching group (47% of participants in the iPad group achieved over 75% compliance compared with 90% of the patching group).  Data were not available for changes in stereopsis nor for contrast sensitivity following treatment. AUTHORS' CONCLUSIONS: Currently, there is only one RCT that offers evidence of the safety and effectiveness of binocular treatment. The authors are moderately confident that after 16 weeks of treatment, the gain in amblyopic eye acuity with binocular treatment is likely comparable to that of conventional patching treatment. However, due to the limited sample size and lack of long term (52 week) follow-up data, it is not yet possible to draw robust conclusions regarding the overall safety and sustained effectiveness of binocular treatment. Further research, using acknowledged methods of visual acuity and stereoacuity assessment with known reproducibility, is required to inform decisions about the implementation of binocular treatments for amblyopia in clinical practice, and should incorporate longer term follow-up to establish the effectiveness of binocular treatment. Randomised controlled trials should also include outcomes reported by users, adherence to prescribed treatment, and recurrence of amblyopia after cessation of treatment.

Prognostic and diagnostic potential of local and circulating levels of pentraxin 3 in lung cancer patients.

There is a well-established link between inflammation and cancer of various organs, but little data are available on inflammation-associated markers of diagnostic and prognostic clinical utility in pulmonary malignancy. Blood samples were prospectively collected from 75 resectable lung cancer patients before surgery and in a cohort of 1,358 high-risk subjects. Serum levels of long pentraxin 3 (PTX3) were determined by high-sensitivity ELISA. PTX3 immunostaining was evaluated by immunohistochemistry in cancer tissue. Serum PTX3 levels in the high-risk population were not predictive of developing subsequent lung cancer or any other malignancy; however, serum PTX3 values in patients with lung cancer were significantly higher compared with cancer-free heavy smokers. With a cutoff of 4.5 ng/ml, specificity was 0.80, sensitivity 0.69, positive predictive value 0.15 and negative predictive value 0.98. The receiver operating curve (ROC) for serum PTX3 had an area under the curve (AUC) of 83.52%. Preoperative serum PTX3 levels in lung cancer patients did not correlate with patient outcome, but high interstitial expression of PTX3 in resected tumor specimens was a significant independent prognostic factor associated with shorter survival (p < 0.001). These results support the potential of serum PTX3 as a lung cancer biomarker in high-risk subjects. Furthermore, PTX3 immunohistochemistry findings support the role of local inflammatory mechanisms in determining clinical outcome and suggest that local expression of PTX3 may be of prognostic utility in lung cancer patients.

Childhood amblyopia: current management and new trends.

INTRODUCTION OR BACKGROUND: With a prevalence of 2-5%, amblyopia is the most common vision deficit in children in the UK and the second most common cause of functional low vision in children in low-income countries. SOURCES OF DATA: Pubmed, Cochrane library and clinical trial registries (clinicaltrials.gov, ISRCTN, UKCRN portfolio database). AREAS OF AGREEMENT: Screening and treatment at the age of 4-5 years are cost efficient and clinically effective. Optical treatment (glasses) alone can improve visual acuity, with residual amblyopia treated by part-time occlusion or pharmacological blurring of the better-seeing eye. Treatment after the end of the conventional 'critical period' can improve vision, but in strabismic amblyopia carries a low risk of double vision. AREAS OF CONTROVERSY: It is not clear whether earlier vision screening would be cost efficient and associated with better outcomes. Optimization of treatment by individualized patching regimes or early start of occlusion, and novel binocular treatment approaches may enhance adherence to treatment, provide better outcomes and shorten treatment duration. GROWING POINTS: Binocular treatments for amblyopia. AREAS TIMELY FOR DEVELOPING RESEARCH: Impact of amblyopia on education and quality of life; optimal screening timing and tests; optimal administration of conventional treatments; development of child-friendly, effective and safe binocular treatments.

Binocular versus standard occlusion or blurring treatment for unilateral amblyopia in children aged three to eight years.

BACKGROUND: Current treatments for amblyopia in children, occlusion and pharmacological blurring, have had limited success, with less than two-thirds of children achieving good visual acuity of at least 0.20 logMAR in the amblyopic eye, limited improvement of stereopsis, and poor compliance. A new treatment approach, based on the dichoptic presentation of movies or computer games (images presented separately to each eye), may yield better results, as it aims to balance the input of visual information from each eye to the brain. Compliance may also improve with these more child-friendly treatment procedures. OBJECTIVES: To determine whether binocular treatments in children aged three to eight years with unilateral amblyopia result in better visual outcomes than conventional occlusion or pharmacological blurring treatment. SEARCH METHODS: We searched the Cochrane Eyes and Vision Group Trials Register (last date of searches: 14 April 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to April 2015), EMBASE (January 1980 to April 2015), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. SELECTION CRITERIA: Two review authors independently screened the results of the search in order to identify studies that met the inclusion criteria of the review: randomised controlled trials (RCTs) that enrolled participants between the ages of three and eight years old with unilateral amblyopia, defined as best-corrected visual acuity (BCVA) worse than 0.200 logMAR in the amblyopic eye, and BCVA 0.200 logMAR or better in the fellow eye, in the presence of an amblyogenic risk factor such as anisometropia, strabismus, or both. Prior to enrolment, participants were to have undergone a cycloplegic refraction and comprehensive ophthalmic examination including fundal examination. In addition, participants had to have completed a period of optical treatment, if indicated, and BCVA in the amblyopic eye had to remain unchanged on two consecutive assessments despite reportedly good compliance with glasses wearing. Participants were not to have received any treatment other than optical treatment prior to enrolment. We planned to include any type of binocular viewing intervention; these could be delivered on different devices including computer monitors viewed with LCD shutter glasses or hand-held screens including mobile phone screens with lenticular prism overlay. Control groups were to have received standard amblyopia treatment; this could include occlusion or pharmacological blurring of the better-seeing eye. We planned to include full-time (all waking hours) and part-time (between 1 and 12 hours a day) occlusion regimens. DATA COLLECTION AND ANALYSIS: We planned to use standard methodological procedures expected by The Cochrane Collaboration. We had planned to meta-analyse the primary outcome, that is mean distance BCVA in the amblyopic eye at 12 months after the cessation of treatment. MAIN RESULTS: We could identify no RCTs in this subject area. AUTHORS' CONCLUSIONS: Further research is required to allow decisions about implementation of binocular treatments for amblyopia in clinical practice. Currently there are no clinical trials offering standardised evidence of the safety and effectiveness of binocular treatments, but results from non-controlled cohort studies are encouraging. Future research should be conducted in the form of RCTs, using acknowledged methods of visual acuity and stereoacuity assessment with known reproducibility. Other important outcome measures include outcomes reported by users, compliance with treatment, and recurrence of amblyopia after cessation of treatment.

Suppressive effects on motion discrimination induced by transient flankers are reduced by perceptual learning.

We investigated spatial suppression of a drifting Gabor target of 0.5 c/° induced by adjacent and iso-oriented stationary Gabors (flankers) whose spatial frequency differed by ±1 and ±2 octaves to that of the drifting target. Stimuli (target and flankers) were presented for 33 ms. Results showed greater spatial suppression when the spatial frequency of the stationary but transient flanking Gabors was either equal or 1-2 octaves lower than when it was 1-2 octaves higher than the target's spatial frequency. This asymmetry was evident only for the drifting target, but not for the stationary target. In addition, we investigated whether perceptual learning (PL) reduced the spatial suppression induced by the flankers. We found that PL increased contrast sensitivity for the target, but only when it was reduced by the lateral masking flankers, and its effect did not transfer to an isolated drifting target of equal or higher spatial frequency. These results suggest that PL selectively affects suppressive interactions rather than contrast gain. We suggest that the suppressive effect of low spatial frequency flankers and the lack of suppression with high spatial frequency flankers may reflect two complementary phenomena: camouflage by the transient flankers (i.e., context) and breaking of camouflage by form-motion segmentation. Camouflage may result because both target and flankers activate the motion (magnocellular) system. Breaking of camouflage instead may occur when target and flankers' spatial frequency are more suitable for quasi-independent activation of the form system (by the flankers) and the motion system (by the target).

A comparison of tests for quantifying sensory eye dominance.

Clinicians rely heavily on stereoacuity to measure binocular visual function, but stereo-vision represents only one aspect of binocularity. Lab-based tests of sensory eye dominance (SED) are commonplace, but have not been translated to wider clinical practice. Here we compare several methods of quantifying SED in a format suitable for clinical use. We tested 30 participants with ostensibly normal vision on eight tests. Seven tests (#1-7) were designed to quantify SED in the form of an interocular balance-point (BP). In tests #1-6, we estimated a contrast-BP, the interocular difference in contrast required for observers to be equally likely to base their judgement on either eye, whereas in test #7 we measured binocular rivalry (interocular ratio of sensory dominance duration). We compare test-retest reliability (intra-observer consistency) and test-validity (inter-observer discriminatory power) and compare BP to stereoacuity (test #8). The test that best preserved inter-observer differences in contrast balance while maintaining good test-retest reliability was a polarity judgement using superimposed opposite-contrast polarity same-identity optotypes. A reliable and valid measure of SED can be obtained rapidly (20 trials) using a simple contrast-polarity judgement. Tests that use polarity-rivalrous stimuli elicit more reliable judgments than those that do not. SIGNIFICANCE STATEMENT: Although sensory eye dominance is central to understanding normal and disordered binocular vision, there is currently no consensus as to the best way to measure it. Here we compare several candidate measures of sensory eye dominance and conclude that a reliable measure of SED can be achieved rapidly using a judgement of stimulus contrast-polarity.

Collision of adenocarcinoma and gastrointestinal stromal tumour (GIST) in the stomach: report of a case.

A 78-year-old woman was diagnosed with a proximal gastric adenocarcinoma and underwent an elective D2 total gastrectomy with splenectomy. Subsequent histopathology revealed the presence of another tumour at the gastric antrum. This was a small benign gastrointestinal stromal tumour (GIST) mixed with gastric adenocarcinoma cells similar to those of the main gastric tumour i.e. a collision tumour. The literature has only few previous reports of this very rare association. It is not known whether this synchronicity is incidental or there is a causative factor inducing the development of tumours of different histotypes in the same organ. Pathologists, oncologists and surgeons should be aware of this interesting condition.

Laparoscopic sleeve gastrectomy after failed gastric banding: is it really effective? Six years of follow-up.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become a valuable surgical option to rescue laparoscopic adjustable gastric banding (LAGB) failures. OBJECTIVES: The aim of this study was to determine whether conversion to LSG after failed LAGB (CLSG) is a well-tolerated and effective rescue procedure compared with primary LSG (PLSG) in the long term. SETTING: University hospital, France. METHODS: A retrospective review of data concerning consecutive patients receiving a LSG between February 2008 and December 2014 was conducted. Mortality, postoperative complications, and weight loss outcomes were analyzed. RESULTS: Of 701 LSG, 601 (85.7%) were PLSG and 100 (14.3%) were CLSG. The mortality rate was 0%. Overall morbidity was comparable between the primary and conversion group (10% versus 6%, P = .27). The mean percentage of excess weight loss at 3, 36, and 72 months was 34.9%, 72.1%, and 57.2% after PLSG and 22.6%, 51.2% and 29.8% after CLSG (P<.05). The failure rate (mean percentage of excess weight loss<50%) was higher in the CLSG group during the first 5 postoperative years (P < .001) with more than two thirds of the CLSG considered as having failed at 60 months. Patients who underwent band ablation as a result of insufficient weight loss or weight regain presented the worst results after conversion to LSG. CONCLUSION: In this study, the conversion of failed LAGB to LSG in 2 steps indicated a safety profile comparable to that of primary LSG but was significantly less effective from the early postoperative course (3 mo) up to 6 years postoperatively. CLSG may not be the best option because a third operation may be needed as a result of insufficient weight loss.

Laparoscopic Sleeve Gastrectomy in Kidney Transplant Candidates: a Case Series.

BACKGROUND: Patients with a body mass index (BMI) >35 kg/m2 who need kidney transplant present with increased postoperative mortality and reduced kidney graft survival compared to patients with a lower BMI. For this reason, obese patients are often excluded from the transplantation waiting list. The aim of this study was to evaluate the feasibility and the results of laparoscopic sleeve gastrectomy (LSG) for obese patients awaiting a kidney transplant. METHODS: This was a retrospective study on patients with dialysis-dependent renal failure (DDRF) operated on at two first-level bariatric centers in Paris (France). All the patients were contraindicated for kidney transplantation due to the presence of morbid obesity. RESULTS: Nine DDFR patients with a mean BMI of 45.9 kg/m2 underwent LSG for the treatment of obesity. Furthermore, all patients presented with hypertension and sleep apnea and six out nine were diabetics. In the immediate postoperative period, all patients were transferred to the intensive care unit (mean stay of 2.1 days). The only major adverse event was a delayed weaning from mechanical ventilation in one patient. The mean hospital stay was 5.5 days (3-12). The total weight loss (TWL) was 27.1, 33.6, and 39.5 kg at 6, 12, and 18 months, respectively. One patient underwent renal transplantation 18 months after LSG, and the other five patients were actively listed for kidney transplantation. CONCLUSIONS: According to the results of this small sample series, LSG seems to be an effective and safe procedure in DDRF patients with concomitant obesity and can increase access to transplantation.

Binocular Therapy for Childhood Amblyopia Improves Vision Without Breaking Interocular Suppression.

Purpose: Amblyopia is a common developmental visual impairment characterized by a substantial difference in acuity between the two eyes. Current monocular treatments, which promote use of the affected eye by occluding or blurring the fellow eye, improve acuity, but are hindered by poor compliance. Recently developed binocular treatments can produce rapid gains in visual function, thought to be as a result of reduced interocular suppression. We set out to develop an effective home-based binocular treatment system for amblyopia that would engage high levels of compliance but that would also allow us to assess the role of suppression in children's response to binocular treatment. Methods: Balanced binocular viewing therapy (BBV) involves daily viewing of dichoptic movies (with "visibility" matched across the two eyes) and gameplay (to monitor compliance and suppression). Twenty-two children (3-11 years) with anisometropic (n = 7; group 1) and strabismic or combined mechanism amblyopia (group 2; n = 6 and 9, respectively) completed the study. Groups 1 and 2 were treated for a maximum of 8 or 24 weeks, respectively. Results: The treatment elicited high levels of compliance (on average, 89.4% ± 24.2% of daily dose in 68.23% ± 12.2% of days on treatment) and led to a mean improvement in acuity of 0.27 logMAR (SD 0.22) for the amblyopic eye. Importantly, acuity gains were not correlated with a reduction in suppression. Conclusions: BBV is a binocular treatment for amblyopia that can be self-administered at home (with remote monitoring), producing rapid and substantial benefits that cannot be solely mediated by a reduction in interocular suppression.

Rare Neurological Complications After Sleeve Gastrectomy.

BACKGROUND: Bariatric surgery is considered to be the most effective treatment of morbid obesity and improvement of obesity-related comorbidities, such as type II diabetes. However, both peripheral and central neurological complications can occur after bariatric surgery. Such complications tend to occur more frequently after bypass surgery than after sleeve gastrectomy (SG). The objective of this study was to identify the patients that presented post-operative neurological complications after undergoing SG and describe the incidence, presentation, and management of these complications. METHODS: This was a retrospective study of 592 cases of SG performed between 2009 and 2014 with a special focus on patients who presented neurological complications. RESULTS: Of the 592 SG cases, only seven (1.18 %) patients presented neurological complications. All patients had uneventful post-operative course, but all reported feeding difficulties, accompanied by severe dysphagia, and rapid weight loss, with a mean weight loss of 35 kg (30-40 kg) 3 months after SG. All patients were readmitted owing to neurological symptoms that included paresthesia, abolition of deep tendon reflexes of the lower limbs, muscle pain, and motor and sensitive deficits in some cases. There were two cases of Wernicke's encephalopathy. All patients were treated for neuropathy secondary to vitamin B1 deficiency and had a significant improvement and/or resolution of their symptoms. CONCLUSIONS: Neurological complications after SG are rare and are often preceded by gastrointestinal symptoms, rapid weight loss, and lack of post-operative vitamin supplementation. Re-hospitalization and multidisciplinary team management are crucial to establish the diagnosis and initiate treatment.

Inguinal Hernia Repair Using Self-adhering Sutureless Mesh: Adhesix™: A 3-Year Follow-up with Low Chronic Pain and Recurrence Rate.

To review our experience and outcomes after inguinal hernia repair using the lightweight self-adhering sutureless mesh "Adhesix™" and demonstrate the safety and efficacy of this mesh. This is a 3-year retrospective study that included 143 consecutive patients who underwent 149 inguinal hernia repairs at our department of surgery. All hernias were repaired using a modified Lichtenstein technique. Preoperative, perioperative, and postoperative data were prospectively collected. Incidence of chronic pain, postoperative complications, recurrence, and patient satisfaction were assessed three years postoperatively by conducting a telephone survey. We had 143 patients with a mean age of 58 years (17-84), who underwent 149 hernia repairs using the Adhesix™ mesh. Ninety-two per cent (131 patients) were males. Only 10 patients (7%) had a postoperative pain for more than three years. In our series, neither age nor gender was predictive of postoperative pain. Only one patient had a hematoma lasting for more than one month and only four patients (2.8%) had a recurrence of their hernia within three years of their initial surgery. Ninety per cent of the patient expressed their satisfaction when surveyed three years after their surgery. In conclusion, the use of the self-adhering sutureless mesh for inguinal hernia repair has been proving itself as effective as the traditional mesh. Adhesix™ is associated with low chronic pain rate, recurrence rate, and postoperative complications rate, and can be safely adopted as the sole technique for inguinal hernia repair.

Two stages conversion of failed laparoscopic adjustable gastric banding to laparoscopic roux-en-y gastric bypass. A study of one hundred patients.

INTRODUCTION: Conversion to laparoscopic gastric bypass (LRYGB) appears to be the treatment of choice after failed LAGB. To reduce the risk of postoperative complications, some surgeons routinely adopt a two-stage strategy. The purpose of this study was to analyze our institution's experience with the two-stage procedure for LAGB conversion to LRYGB MATERIALS AND METHODS: The bariatric database of our institution was reviewed to identify patients who had undergone conversion of LAGB to LRYGB from November 2007 to June 2012. RESULTS: One hundred patients were included. Of these, 62 (62%) required conversion to LRYGB for inadequate weight loss or weight regain and 38 for band-related complications. All the procedures were performed in two stages and laparoscopically. The average time between band removal and LRYGB was 17.3 months. The mean follow-up after LRYGB was 31 ± 18.7 months. The mean BMI prior to LRYGB conversion was 45.3 ± 5.2. Early complications occurred in 15 patients (15%), while late complications occurred in only 3 patients (3%). The average %EWL at 24 months and 48 months after conversion was 70.1 and 69.4%, respectively. CONCLUSION: Although a two-stage conversion strategy increases the number of operations and hospital stay without decreasing the rate of early complications compared to one-stage conversion; it has shown to be associated with low rates of GJA stenosis and excellent %EWL.

Valence-specific modulation in the accumulation of perceptual evidence prior to visual scene recognition.

Visual scene recognition is a dynamic process through which incoming sensory information is iteratively compared with predictions regarding the most likely identity of the input stimulus. In this study, we used a novel progressive unfolding task to characterize the accumulation of perceptual evidence prior to scene recognition, and its potential modulation by the emotional valence of these scenes. Our results show that emotional (pleasant and unpleasant) scenes led to slower accumulation of evidence compared to neutral scenes. In addition, when controlling for the potential contribution of non-emotional factors (i.e., familiarity and complexity of the pictures), our results confirm a reliable shift in the accumulation of evidence for pleasant relative to neutral and unpleasant scenes, suggesting a valence-specific effect. These findings indicate that proactive iterations between sensory processing and top-down predictions during scene recognition are reliably influenced by the rapidly extracted (positive) emotional valence of the visual stimuli. We interpret these findings in accordance with the notion of a genuine positivity offset during emotional scene recognition.

High-grade poorly differentiated retroperitoneal sarcoma. Report of a case and review of the literature.

Retroperitoneal sarcomas (RPS) are uncommon tumors associated with a poor prognosis. This is particularly true in case of high-grade sarcomas of specific histological subtypes, as demonstrated by the largest surveys of the last decade. Up to the present day, unfortunately there are no powerful tools available except for surgery. On the other hand, the resection rate of RPS is significantly increased over the last decades allowing to deliver the best treatment available. This paper reports on the case of a young patient who was incidentally diagnosed with a retroperitoneal mass. The patient underwent surgery in our department and the histological report showed a spindle cell sarcoma of high grade of malignancy with an incomplete muscular phenotype. The patient was discharged on the seventh postoperative day and he is still free of local and distant recurrence.

Visceral artery aneurysms in liver transplant candidates and in patients after liver transplantation.

There are only few reviews concerning visceral aneurysms in cirrhotics, and a small number of papers on visceral aneurysms in liver transplant patients. The present paper investigates this condition in both groups of patients in a 10-year-retrospective study.

Arthritis of the sternoclavicular joint masquerading as rupture of the cervical oesophagus: a case report.

INTRODUCTION: Sternoclavicular septic arthritis is a rare condition and accounts only for 1% of cases of septic arthritis in the general population. The most common risk factors are intravenous drug use, central-line infection, distant-site infection, immunosuppression, trauma and diabetes mellitus. This is a report of an unusual case where this type of arthritis was masquerading as rupture of the cervical oesophagus. CASE PRESENTATION: A 63-year-old man presented complaining of right neck pain and dysphagia following a bout of violent coughing. Physical examination revealed cellulitis extending from the right sternoclidomastoid region to the anterior upper chest. Computed tomography showed inflammatory changes behind the right sternoclavicular joint with mediastinitis and ipsilateral pleural effusion. These findings raised the suspicion of spontaneous rupture of the cervical oesophagus. Management involved jejunal feeding along with broad-spectrum antibiotics. The inflammation, however, relapsed after discontinuation of the antibiotics and this time, computed tomography pointed to a diagnosis of arthritis of the sternoclavicular joint. The patient responded completely to a 6-week course of oral penicillin, flucloxacillin and metronidazole. CONCLUSION: Sternoclavicular arthritis is a rare condition that has been associated with a variety of predisposing factors. It may, however, occur in otherwise completely healthy individuals and should be included in the differential diagnosis of other inflammatory conditions of the neck and upper chest.
