Massive mixed epithelial-stromal tumour of seminal vesicle requiring challenging abdominoperineal resection: a case report and review of literature

Mixed epithelial-stromal tumours (MESTs) are a rare biphasic tumour that frequently arise in women from the renal and urogenital tract. They are also seen in men but are exceptionally uncommon with only few cases reported to originate from the seminal vesicles. Malignant transformation of its epithelial or stromal components is possible; however, by in large, these tumours are benign in nature. We report the case of a 48-year-old man with no remarkable medical or surgical history who presented with a huge expanding pelvic and intra-abdominal mass that required extensive surgical management including a pelvic exenteration. Histopathological analysis concluded the diagnosis of benign MEST originating from the seminal vesicles with no malignant features. No further systemic therapy was recommended for our patient. Given the technical intricacy in the operative resection of this tumour, we aim to present our findings and surgical management of this complex MEST.

Massive and Irreparable Rotator Cuff Tears: A Review of Current Definitions and Concepts

Background

While massive and irreparable rotator cuff tears (MIRCTs) have been abundantly studied, inconsistent definitions in the literature and theories about pain and dysfunction related to them can be difficult to navigate when considering an individual patient.

Purpose

To review the current literature for definitions and critical concepts that drive decision-making for MIRCTs.

Study Design

Narrative review.

Methods

A search of the PubMed database was performed to conduct a comprehensive literature review on MIRCTs. A total of 97 studies were included.

Results

Recent literature reflects added attention to clarifying the definitions of "massive, "irreparable," and "pseudoparalysis." In addition, numerous recent studies have added to the understanding of what generates pain and dysfunction from this condition and have reported on new techniques for addressing them.

Conclusion

The current literature provides a nuanced set of definitions and conceptual foundations on MIRCTs. These can be used to better define these complex conditions in patients when comparing current surgical techniques to address MIRCTs, as well as when interpreting the results of new techniques. While the number of effective treatment options has increased, high-quality and comparative evidence on treatments for MIRCTs is lacking.

Extensive Keloid and Hypertrophic Mixed Scarring Pattern in Ear Lobes of a 14-Year-Old African Female: A Case Report

Background Massive earlobe scarring/keloid formation can occur after ear piercing in individuals of African descent. Case report: A 14-year-old African girl with pierced ears in childhood presented with two progressively growing and disfiguring tumors on both earlobes. The maximum diameter of each lesion was 5.5 centimeters, and the weight of each lesion was approximately 20 grams. Histologically, there was a mixed pattern of keloid and hypertrophic scarring. Discussion: Massive keloids can occur after ear piercing in childhood. It is unclear why some individuals develop these massive keloids.

Massive Irreparable Rotator Cuff Tears: Which Patients Will Benefit from Physiotherapy Exercise Programs? A Narrative Review

Massive irreparable rotator cuff tears can cause significant shoulder pain, disability and reduction in quality of life. Treatment approaches can be operative or non-operative. Operative approaches include reverse total shoulder arthroplasty, arthroscopic debridement, partial rotator cuff repair, subacromial balloon spacers, superior capsule reconstruction, and tendon transfer procedures. Non-operative approaches include physiotherapy exercise programs and corticosteroid injections. There are no randomized controlled trials comparing the different treatment approaches. It is therefore challenging for clinicians to advise patients on what is their best treatment pathway. Physiotherapy exercise programs are less expensive and have lower risks for patients than surgical approaches. However, the success of physiotherapy in patients with massive irreparable rotator cuff tears is highly variable with published success rates of 32-96%. Several cohort studies have sought to identify if certain factors are predictive of success with physiotherapy. Several biomechanical factors were identified as possibly being related to a successful or unsuccessful outcome following physiotherapy, with complete tear of subscapularis demonstrating the strongest evidence. However, there were no appropriately designed prognostic studies. There has been a strong emphasis on biomechanical factors. Other domains such as psychosocial factors, which are important in similar patient populations, have not been explored. We recommend that further research is needed in this area and should include randomized controlled trials comparing treatment approaches and longitudinal prospective prognostic studies to identify predictors of treatment success.

Blood component ratios in children with non-traumatic life-threatening bleeding

BACKGROUND AND OBJECTIVES

In paediatric trauma patients, there are limited prospective data regarding blood components and mortality, with some literature suggesting decreased mortality with high ratios of plasma and platelets to red blood cells (RBCs) in massive transfusions; however, most paediatric massive transfusions occur for non-traumatic aetiologies and few studies assess blood product ratios in these children. This study's objective was to evaluate whether high blood product ratios or low deficits conferred a survival benefit in children with non-traumatic life-threatening bleeding.

MATERIALS AND METHODS

This is a secondary analysis of the five-year, multicentre, prospective, observational massive transfusion epidemiology and outcomes in children study of children with life-threatening bleeding from US, Canadian and Italian medical centres. Primary interventions were plasma:RBC and platelets:RBC (high ratio ≥1:2 ml/kg) and plasma and platelet deficits. The primary outcome was mortality at 6 h, 24 h and 28 days. Multivariate logistic regression models were used to determine independent associations with mortality.

RESULTS

A total of 222 children were included from 24 medical centres: 145 children (median [interquartile range] age 2.1 years [0.3-11.8]) with operative bleeding and 77 (8.0 years [1.2-14.7]) with medical bleeding. In adjusted analyses, neither blood product ratios nor deficits were associated with mortality at 6 h, 24 h or 28 days.

CONCLUSION

This paper addresses a lack of prospective data in children regarding optimal empiric massive transfusion strategies in non-traumatic massive haemorrhage and in finding no decrease in mortality with high plasma or platelet to RBC ratios or lower deficits supports an exploratory analysis for mortality.

Evaluation of spin in systematic reviews and meta-analyses of superior capsular reconstruction

BACKGROUND

Small, preliminary studies and the systematic reviews on superior capsular reconstruction (SCR) that collate data are at increased risk spin. This study's primary objective was to identify, describe, and account for the incidence of spin in systematic reviews of SCR. This study's secondary objective was to characterize the studies in which spin was identified to determine whether identifiable patterns of characteristics exist among studies with spin.

METHODS

This study was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using a predetermined protocol. A search was conducted on the PubMed and Embase databases for systematic reviews and meta-analyses on SCR. Screening and data extraction were conducted independently by 2 authors. Each included study's abstract was assessed for the presence of the 15 most common types of spin, with full texts reviewed during cases of disagreement or for clarification. General data that were extracted included study title, authors, publication year, journal, level of evidence, study design, funding source, reported adherence to PRISMA guidelines, preregistration of the study protocol, and primary and secondary outcome measures. Full texts were used in the assessment of study quality per AMSTAR 2.

RESULTS

We identified 53 studies during our search, of which 17 met the inclusion criteria. At least 1 form of spin was observed in all 17 studies. The most common types of spin were type 5 ("The conclusion claims the beneficial effect of the experimental treatment despite a high risk of bias in primary studies") and type 9 ("Conclusion claims the beneficial effect of the experimental treatment despite reporting bias"), both of which were observed in 11 studies (11 of 17, 65%). A statistically significant association between lower level of evidence and type 5 ("The conclusion claims the beneficial effect of the experimental treatment despite a high risk of bias in primary studies") was observed (P = .0175). A statistically significant association was also found between more recent year of publication and the spin category misleading interpretation (P = .0398), and between lower AMSTAR 2 score and type 13 ("Failure to specify the direction of the effect when it favors the control intervention") (P = .0260). No other statistical associations between other study characteristics were observed.

CONCLUSION

Spin is highly prevalent in abstracts of SCR systematic reviews and meta-analyses. An association was found between the presence of spin and lower level of evidence, year of publication, and AMSTAR 2 ratings.

Novel marker for predicting the severity and prognosis of acute pulmonary embolism: platelet-to-hemoglobin ratio

Background: We investigated the ability of the platelet-to-hemoglobin ratio (PHR) to predict mortality and disease severity in patients with acute pulmonary embolism (APE). Materials & methods: The severity of APE was classified as massive (high risk), submassive (intermediate risk) or nonmassive (low risk). PHR is defined as platelet count/hemoglobin count. Results: PHR was significantly higher in patients with massive APE, and this elevation showed a gradual increase from the nonmassive group to the massive group (p < 0.001). In-hospital and 1-month mortality were higher in patients with high PHR values. PHR was an independent risk factor for the development of massive APE (odds ratio: 1.014; 95% CI: 1.011-1.017; p = 0.009). Conclusion: PHR values predicted massive APE and were an independent predictor of mortality in APE.

Advantages of 3-dimensional Measurements for Supraspinatus Intramuscular Fatty Evaluation in Patients With Medium to Massive Rotator Cuff Tears: Comparison With a Single Sagittal Slice

BACKGROUND

Fatty infiltration of the rotator cuff muscles is highly related to poor outcomes after rotator cuff tears. Fat fraction (FF) based on traditional 2-dimensional measurements (2D-FF) from a single sagittal Y-view slice cannot determine intramuscular FF in the rotator cuff muscles; the newly developed 3-dimensional method (3D-FF) is supposed to precede 2D measurements for intramuscular FF evaluation in accuracy and reliability.

PURPOSE

(1) To measure 3D-FF and (2) to compare 3D-FF and 2D-FF in terms of quantitative values and intra- and interobserver agreement.

STUDY DESIGN

Cohort study (diagnosis); Level of evidence, 2.

METHODS

Six-point Dixon magnetic resonance imaging was performed in patients with full-thickness supraspinatus tears. 2D-FF was calculated on a single sagittal Y-view. Semiautomatic segmentation software (ITK-SNAP) was used to reconstruct 3D volumes of the supraspinatus muscle and fat. 3D-FF was obtained by dividing the fat volume by the total volume of the supraspinatus muscle. A paired t test was used to compare the individual differences between 2D-FF and 3D-FF results. Linear regression and Bland-Altman analyses were performed to determine the agreement between 2D-FF and 3D-FF. Intraclass correlation coefficients (ICCs) were calculated to determine intra- and interobserver agreement.

RESULTS

The 3D muscular and fatty models presented an inhomogeneous distribution of intramuscular fat in the supraspinatus, indicating the superiority of 3D-FF over 2D-FF in capturing all muscle morphologic information. 2D-FF was significantly higher than 3D-FF in the supraspinatus with large (19.5% ± 5.9% vs 16.2% ± 3.7%; P = .002) and massive (34.8% ± 13.3% vs 26.2% ± 9.4%; P < .001) rotator cuff tears. 2D-FF overestimated the FF compared with 3D-FF by >50% in 14.7% of all patients and by >15% in 67.6% of patients with large or massive RCTs. The discrepancy between 2D-FF and 3D-FF increased with increasing mean FF. The intra- and interobserver agreement of 3D-FF (ICCs, 0.89-0.99 and 0.89-0.95) was superior to that of 2D-FF (ICCs, 0.71-0.95 and 0.64-0.79).

CONCLUSION

3D-FF indicated an inhomogeneous distribution of intramuscular fat by capturing all muscle and fat morphologic information. In patients with large and massive rotator cuff tears, 2D-FF of the supraspinatus was significantly higher than 3D-FF. 3D-FF was more reliable than 2D-FF for estimating fatty infiltration in the supraspinatus, with better intra- and interobserver agreement.

Transfusion practice in the bleeding critically ill: An international online survey-The TRACE-2 survey

BACKGROUND

Transfusion is very common in the intensive care unit (ICU), but practice is highly variable, as has recently been shown in non-bleeding critically ill patients practices survey. Bleeding patients in ICU require different blood products across a range of specific patient categories. We hypothesize that a large variety in transfusion practice exists in bleeding patients.

STUDY DESIGN AND METHODS

An international online survey was performed among physicians working in the ICU. Transfusion practice in massively and non-massively bleeding patients was examined, including transfusion ratios, thresholds, and the presence of transfusion guidelines.

RESULTS

Six hundred eleven respondents filled in the survey of which 401 could be analyzed, representing 64 countries. Among the respondents, 52% had a massive transfusion protocol (MTP) available at their ICU. In massively bleeding patients, 46% of the respondents used fixed transfusion component ratios. Of those who used fixed blood ratios, the 1:1:1 ratio (red blood cell [RBC] concentrates: plasma: platelet concentrates) was most commonly used (33%). The presence of an MTP was associated with a more frequent use of fixed ratios (p < .001). For RBC transfusion in the general non-massively bleeding ICU population, a hemoglobin (Hb) threshold of 7.0[7.0-7.3] g/dl was reported. In the general ICU population, a platelet count threshold of 50[26-50] × 10⁹ /L was applied.

DISCUSSION

Half of the centers had no massive transfusion protocol available. Transfusion practice in massively bleeding critically ill patients is highly variable and driven by the presence of an MTP. In the general non-massively bleeding ICU population restrictive transfusion triggers were chosen.

Factors associated with the development of early- to mid-term cuff-tear arthropathy following arthroscopic rotator cuff repair

BACKGROUND

Few studies have specifically evaluated the development of cuff-tear arthropathy (CTA) after a rotator cuff repair in the postoperative early to mid-term. This study aimed to identify the factors associated with the development of CTA, to evaluate the effect of arthropathy on functional outcomes, and to evaluate the incidence of CTA 3-10 years after an arthroscopic rotator cuff repair.

METHODS

A total of 312 patients who underwent an arthroscopic repair of a large or massive full-thickness rotator cuff tear with a minimum follow-up of 3 years were retrospectively divided into 2 groups for analysis: those with postrepair CTA (arthritic glenohumeral changes due to rotator cuff insufficiency) and those without. CTA was assessed using the Seebauer and modified Hamada-Fukuda classification systems. Pre-, intra-, and postoperative patient characteristics; characteristics of the rotator cuff tear; clinical and radiological parameters; and pre- and postoperative functional scores were compared.

RESULTS

The rate of development of CTA was 11.5% (36 of 312 patients, 13 centric and 23 eccentric arthropathy). CTA was more frequently associated with the poor integrity of the supraspinatus tendon after repair (P < .001) and massive tears (P = .006). Postoperative pseudoparalysis (P < .001), symptomatic retear (P < .001), tear size (P = .026), critical shoulder angle (P = .001), preoperative acromiohumeral interval (P = .046), and the humeral head superior migration (P = .001) were found to be associated with the development of CTA. However, only postoperative pseudoparalysis was found to be an independent risk factor (P < .001, odds ratio: 2.965). Patients with postrepair CTA had significantly worse functional outcome scores.

CONCLUSION

The postoperative development of pseudoparalysis may be a marker of CTA in the future and that closer follow-up may be necessary.

Outcomes of Arthroscopic Nerve Release in Patients Treated for Large or Massive Rotator Cuff Tears and Associated Suprascapular Neuropathy: A Prospective, Randomized, Double-Blinded Clinical Trial

BACKGROUND

Suprascapular neuropathy has been observed in the setting of rotator cuff tears (RCTs), but its association with these tears and their treatment are unclear.

HYPOTHESIS

Arthroscopic suprascapular nerve release during rotator cuff repair will not alter the outcomes of neuropathy.

STUDY DESIGN

Randomized controlled trial; Level of evidence, 1.

METHODS

A total of 42 patients with large/massive reparable RCTs and suprascapular neuropathy were recruited and followed up at 6 and 12 months. Electrophysiological results as well as Disabilities of the Arm, Shoulder and Hand (DASH), American Shoulder and Elbow Surgeons (ASES), and Constant scores were evaluated at selected time periods. Patients were randomly assigned to 2 groups. Patients in the control group underwent arthroscopic repair of the rotator cuff without combined arthroscopic release of the superior transverse scapular ligament; in the second group, the superior transverse ligament was released. The primary outcome was to examine full suprascapular nerve recovery through electrophysiological changes between groups. The secondary/tertiary outcomes were analysis of clinical outcomes and assessment of the relation between RCT size and the degree of suprascapular nerve recovery. Patients, clinical staff members, and the neurologist were blinded to the type of surgical procedure.

RESULTS

Of 42 patients, 37 completed the follow-up at 12 months (median age, 64 years [range, 50-75 years]). Overall, 17 of 19 (89.5%) patients in the control group and 15 of 18 (83.3%) patients in the nerve release group had full nerve recovery, with no significant difference between the 2 groups. Clinically, all patients in both groups showed a significant improvement (P < .001), but no significant difference was observed between the 2 groups in terms of 12-month postoperative scores (control group: DASH: median, 5 [range, 0-21]; ASES: median, 88 [range, 83-98]; Constant: median, 86 [range, 70-98]) (nerve release group: DASH: median, 6 [range, 0-25]; ASES: median, 90 [range, 83-98]; Constant: median, 88 [range, 75-98]). Also, no significant difference was found between the 2 groups regarding other secondary and tertiary outcomes.

CONCLUSION

Combined arthroscopic release of the superior transverse scapular ligament and rotator cuff repair in patients with large/massive RCTs and suprascapular neuropathy did not produce statistically significant improved outcomes compared with repair of the rotator cuff alone.

"Peanut saves the day": an innovative solution to massive, cryptogenic haemoptysis-a case study

Massive (or life-threatening) haemoptysis is a time-sensitive emergency encountered by a physician that requires an interdisciplinary, collaborative effort to arrest the bleeding in a prompt and timely manner. Placement of an endobronchial Watanabe spigot (EWS) to halt haemoptysis is a relatively recent technique finding its wide application in airway pathology, with the current extension of its use to bronchial bleeding. However, the lack of immediate access to EWS gives rise to the need to innovate with day-to-day materials used in routine surgical practice and available in resource-limited settings, which may serve the purpose of a spigot. In this report, we bring to light a case of life-threatening, cryptogenic haemoptysis that was managed by a novel technique of using peanut gauze as a spigot resulting in a successful endobronchial tamponade.

Idiopathic bilateral massive perirenal subcapsular effusion: The first case in the literature

INTRODUCTION

Bilateral perirenal subcapsular effusion is a rare clinical condition and is associated with several underlying etiologies. We present a 33 years old male patient with idiopathic bilateral massive subcapsular effusion.

CASE PRESENTATION

A 33-year-old male patient presented to our outpatient clinic with bilateral flank pain and fever for 2 weeks. Bilateral perirenal subcapsular effusion was detected in intravenous contrast-enhanced CT and dynamic MRI.

TREATMENT

Bilateral ultrasound-guided percutaneous drainage was performed by an expert uroradiologist to reduce the parenchymal pressure, Control CT imaging after 6 weeks demonstrate that bilateral normal kidneys.

DISCUSSION

It has been reported that subcapsular and perirenal effusion is a rare clinical condition that may develop secondary to causes such as Nephrotic syndrome, Eisenmenger Syndrome, Lymphangiomatosis, and Page Kidney Disease. In our case, the clinical symptoms of the patient regressed after the whole effusion fluid was drained. No underlying pathology was found in further examinations. Therefore, we present the first case of Idiopathic Bilateral Massive Perirenal Subcapsular Effusion in the literature.

Clinical outcome of massive acetaminophen overdose treated with standard-dose N-acetylcysteine

BACKGROUND

Recent recognition of "massive" acetaminophen (APAP) overdoses has led to the question of whether standard dosing of N-acetylcysteine (NAC) is adequate to prevent hepatoxicity in these patients. The primary aim of this study was to evaluate the clinical outcome for patients with massive APAP overdose who received standard intravenous NAC dosing of 300 mg/kg over 21 h.

METHODS

This was a single-center retrospective cohort study conducted by chart review of APAP overdoses reported to a regional poison center from 1 January 2010 to 31 December 2019. Massive APAP overdose was defined by single, acute overdose resulting in an APAP concentration exceeding 300 mcg/mL at 4 h post-ingestion. Standard univariate statistical analysis was conducted to describe the cohort, and a multivariate logistic model was utilized to calculate adjusted odds ratios for risk of hepatoxicity.

RESULTS

1425 cases of APAP overdose were reviewed. 104 cases met the inclusion criteria of massive APAP overdose. Overall, 79 cases (76%) had no acute liver injury or hepatotoxicity, and 25 (24%) developed hepatoxicity. Nine percent (n = 4) of cases receiving NAC within 8 h developed hepatotoxicity. Crude odds for hepatoxicity was 5.5-fold higher for cases who received NAC after 8 h.

CONCLUSIONS

Standard NAC dosing received within 8 h prevented hepatoxicity in 91% (n = 40) of cases in our series of massive APAP overdoses. Additional data is needed to determine the clinical outcomes of massive APAP overdose using current intravenous NAC dosing.

Congenital Hepatic Arteriovenous Malformation Presenting as Isolated Massive Hepatomegaly in an Otherwise Healthy Neonate: A Case Report

Congenital hepatic arteriovenous malformations (HAVMs), though rare, carry high morbidity and mortality rates if left undiagnosed. The usual clinical presentation is in infancy with congestive heart failure, anaemia and hepatomegaly. There are reports of presentation as persistent pulmonary hypertension in newborns and reports of their spontaneous regression as well. We describe a healthy full-term neonate with HAVM who was presented with isolated massive hepatomegaly and underwent surgical ligation.

[Massive rotator cuff injury: arthroscopic treatment with upper capsular reconstruction]

Massive rotator cuff injuries (LMMRs) are those breaks of more than 5 cm either the anteroposterior plane, or lateromedial plane. Some authors consider them to be complete ruptures of at least two rotator cuff tendons. The clinical case of a 63-year-old man with this type of injury that was resolved by the superior capsule reconstruction technique is presented, technical details and some of the literature review to carry out the procedure are shown.

Interventional Algorithm in Gastrointestinal Bleeding-An Expert Consensus Multimodal Approach Based on a Multidisciplinary Team

The approach to the patient with gastrointestinal bleeding (GIB) can be very complex. A multidisciplinary panel of physicians with expertise in Gastroenterology, Anesthesiology, and Transfusion Medicine worked together to provide the best knowledge and guide clinical practitioners in the real setting of health institutions, characterized by disparate availability of human and technical resources. The authors propose a global and personalized approach according to different clinical scenarios to improve the outcomes of patients with GIB, for whom the reduction of inappropriate transfusions is crucial. The goal of this document is to provide clear and objective guidance through interventional algorithms toward a goal-directed approach according to the clinical situation and supported by the latest available scientific data on GIB management in different settings.

Massive transfusion in The Netherlands

OBJECTIVES

Massive transfusion protocols (MTPs) may improve survival in patients with uncontrolled haemorrhage. An MTP was introduced into the Dutch transfusion guidelines in 2011, the ninth edition of the advanced trauma life support course in 2012 and the third version of the European guideline in 2013. This is the first survey of MTPs in Dutch trauma centres.

METHODS

The aim of the study was to compare MTP strategies in level 1 trauma centres in The Netherlands, and with (inter)national guidelines. A contact in each government assigned level 1 trauma centre in The Netherlands and the Dutch Ministry of Defence was approached to share their MTPs and elucidate their protocol in a survey and oral follow-up interview.

RESULTS

All 11 level 1 trauma centres responded. The content of the packages and transfusion ratios (red blood cells/plasma/platelets) were 3:3:1, 5:5:1, 5:3:1, 2:3:1, 4:4:1, 5:2:1, 2:2:1 and 4:3:1. Tranexamic acid was used in all centres and an additional dose was administered in eight centres. Fibrinogen was given directly (n=4), with persistent bleeding (n=3), based on Clauss fibrinogen (n=3) or rotational thromboelastometry (n=1). All centres used additional medication in patients in the form of anticoagulants, but their use was ambiguous.

CONCLUSION

MTPs differed between institutes and guidelines. The discrepancies in transfusion ratios can be explained by (inter)national differences in preparation and volume of blood components and/or interpretation of the '1:1:1' guideline. We recommend updating MTPs every year using the latest guidelines and evaluating the level of evidence for treatment during massive transfusion.

Surgical treatment of spontaneous brainstem hemorrhage: A case report

RATIONALE

The improvement of microneurosurgery and neuroimaging, as well as neuronavigation and neurophysiological monitoring, enables neurosurgeons to safely and accurately resect lesions on the brainstem.

PATIENT CONCERNS

A 54-year-old man, with 2-year history of hypertension, presented with sudden loss of consciousness for 1.5 hours.

DIAGNOSES

Spontaneous brainstem hemorrhage.

INTERVENTIONS

We performed posterior fossa decompression together with hematoma evacuation in the super early stage for the patient.

OUTCOMES

The patient regained normal spontaneous breathing function after surgery. And he needed help for daily activities with hemiplegia of right limb at three-month follow-up.

LESSONS

The hematoma evacuation together with posterior fossa decompression in the super early stage maybe a good treatment for patients in a deep coma with a large hematoma at the dorsal side.

Sub-acromial balloon spacer for irreparable rotator cuff tears: Is it an appropriate salvage procedure?

INTRODUCTION

Irreparable rotator cuff tear (RCT) presents a difficult treatment challenge for the orthopaedic surgeon. Many treatment strategies with varying degrees of success have been performed over the years. One of the suggested surgical treatment options is the use of a biodegradable sub-acromial balloon spacer.

METHODS

A retrospective study of patients treated with sub-acromial balloon spacer between the years 2011 and 2016 was conducted. Mean follow-up time was 14.4 months. Patient charts were reviewed to evaluate the early clinical results and complications of sub-acromial spacer for irreparable RCTs.

RESULTS

The study cohort included 24 shoulders in 22 patients. The average postoperative Disability of the Arm, Shoulder and Hand score was 62.4. The average preoperative University of California at Los-Angeles Shoulder score was 10.9 and improved to 15.9 ( p = 0.001). Forty-six per cent of patients were satisfied with their clinical postoperative outcome. We found moderate-strong positive correlation ( r = 0.64) between preoperative range of motion (ROM) and general satisfaction. None of the postoperative radiographs showed an improvement regarding the proximal migration of the humeral head. In total, four (16.7%) patients experienced postoperative complications, and two (8.3%) patients required an additional surgery as a consequence of a postoperative complication.

CONCLUSION

Our results show unsatisfactory improvement in patients with irreparable RCT treated with the sub-acromial balloon spacer. Careful patient selection with attention to preoperative ROM should be considered.

LEVEL OF EVIDENCE

Therapeutic level IV.

Massive subcutaneous emphysema after traumatic pneumothorax

A simple case/asymptomatic pneumothorax not deemed to necessitate drainage can quickly change, and patient safety can be compromised. Chest tube insertion with increased suction is considered a safe and efficient strategy in patients with extensive subcutaneous emphysema following traumatic pneumothorax.

Long-term results of reverse total shoulder arthroplasty for rotator cuff dysfunction: a systematic review of longitudinal outcomes

BACKGROUND

The aim of this systematic review was to evaluate the longitudinal evolution of midterm to long-term results of reverse total shoulder arthroplasty (RTSA) for patients with massive irreparable rotator cuff tears (miRCT).

METHODS

Databases were scanned for studies of RTSA for miRCT. Studies with a minimum Level IV of evidence were considered eligible. Studies were included if they reported a minimum of 5 years of follow-up and excluded if they reported RTSA combined with tendon transfers or as revision arthroplasty. Data were grouped based on results after 5 to 7 years, 7 to 10 years, and 10 to 20 years of follow-up.

RESULTS

Eight studies with a total of 365 shoulders were included. After a mean follow-up of 9.5 years (range, 5-20 years), the preoperative absolute and relative Constant scores were significantly improved from 24 to 59 points (P = .004) and from 33% to 74% (P = .009). The preoperative Subjective Shoulder Value improved from 23% to 72% (P = .049). Active anterior elevation and abduction also improved significantly (P = .004 and P = .014, respectively), but active external rotation remained unchanged (P = .855). None of the clinical scores or active ranges of motion significantly deteriorated up to 20 years after the operation (P > .05). After 10 years, 42% of the RTSAs showed grade III or IV inferior scapular notching.

CONCLUSION

Pooled long-term results of RTSA for miRCT show significant improvement of overhead function and of objective and subjective outcome scores up to 20 years after surgery. Shoulder function and outcome scores also showed no significant deterioration between 5 and 20 years of follow-up. Longer follow-up will be needed to determine ultimate longevity.

Three-dimensional shoulder motion after teres major or latissimus dorsi tendon transfer for posterosuperior rotator cuff tears

BACKGROUND

Teres major (TM) transfer and latissimus dorsi (LD) transfer are essential treatment options in patients with posterosuperior rotator cuff (RC) tears. The purpose of this study was to quantify shoulder kinematics before and after TM transfer and LD transfer in posterosuperior RC tear patients.

METHODS

In this prospective cohort study, we quantitatively measured shoulder movements using an electromagnetic tracking device (Flock of Birds) preoperatively and 1 year after either TM (n = 13) or LD (n = 9) tendon transfer. Additional outcome measures included the Constant score (CS), patient-reported pain, and quantitative range of motion. Scapular kinematics were evaluated during arm abduction.

RESULTS

By use of a quantitative assessment, forward flexion (from 87° to 106°, P = .007), abduction (from 86° to 106°, P = .010), and external rotation in abduction (from 52° to 70°, P = .019) improved. Both transfers reduced pain (from 50 to 10 mm, P < .001), and the CS improved (from 37 to 62 points, P < .001). No significant differences in postoperative improvement in pain and function were found between TM and LD tendon transfers. The TM transfer group showed increased scapular lateral rotation compared with the LD transfer group (13°; 95% confidence interval [CI], 4.8° to 21.7°; P = .003). We were unable to detect differences between TM transfer and LD transfer in the change in protraction (3.2°; 95% CI, -6.3° to 12.8°; P = .489) and posterior tilt (3.5°; 95% CI, -3.5° to 10.5°; P = .313).

CONCLUSION

Tendon transfer surgery resulted in an overall improvement in CS, pain relief, and quantitative range of motion in the treatment of an irreparable posterosuperior RC tear. Scapular lateral rotation gradually increased after TM transfer, reminiscent of RC function, whereas such an increase was not observed after LD transfer.

Solitary massive lipoma in the planter aspect of great toe presenting as two masses

Lipoma is rare in the planter aspect of the toes, and only few cases of massive lipoma have been reported in this site. The differential diagnosis of masses in the foot and toes is wide, and clinical diagnosis may be challenging. Access to magnetic resonance imaging, a standard diagnostic investigation for such soft tissue masses of the foot and toes, may be limited in some practice, requiring a reliance on clinical signs. We report a solitary massive lipoma in the planter aspect of the right great toe that appeared as two masses and with modification of typical clinical signs of lipoma.

Cement Casting to Optimize Reconstruction of Chronic Osteochondral Lesions of the Talus

Few surgical techniques have been described for reconstruction in massive osteochondral lesions of the talus, and there is limited evidence of techniques for accurately reproducing native talar anatomy with bone auto/allograft techniques. In this article, we present a novel technique, which is highly reproducible, using bone cement to restore the congruence and anatomy of the ankle joint.

Long-term outcome of tuberoplasty for irreparable massive rotator cuff tears: is tuberoplasty really applicable?

BACKGROUND

Tuberoplasty is a therapeutic option for irreparable massive rotator cuff tear (RCT). However, no study has reported long-term outcomes after arthroscopic tuberoplasty.

METHODS

We evaluated 16 patients who underwent arthroscopic tuberoplasty for symptomatic irreparable massive RCT without pseudoparalysis. Patients were a mean age of 64 years (range, 43-80 years) at the time of the operation, and the mean duration of follow-up was 98 months (range, 84-126 months).

RESULTS

At the last follow-up, the visual analog scale score for pain during motion had decreased to 2.3 from a preoperative mean of 6.9 (P < .001). The mean University of California at Los Angeles and Constant scores improved from 10.3 and 37.9 preoperatively to 27.2 and 59.2, respectively, at the last follow-up (P < .001 for both). The best University of California at Los Angeles (UCLA) and Constant scores during the follow-up duration were 28.3 and 60.3, respectively, at 5 years. The mean acromiohumeral interval changed from 5 mm preoperatively to 4 mm at the last follow-up. The rate of continuity in the inferior scapulohumeral line decreased significantly from 69% (11 shoulders) preoperatively to 19% (3 shoulders) at the last follow-up (P = .011). Only 1 patient underwent revision surgery.

CONCLUSIONS

Arthroscopic tuberoplasty yielded satisfactory outcomes during a mean 8-year follow-up period. Although superior migration of the humeral head progressed with time, the clinical outcomes were not affected. Arthroscopic tuberoplasty is a good option for relieving pain and improving functionality in nonpseudoparalytic patients with painful irreparable massive RCT.

Human immunodeficiency virus infection in a child revealed by a massive purulent pericarditis mistaken for a liver abscess due to Staphylococcus aureus

Massive purulent andacute pericarditis in children is a life-threatening disease associated with high mortality. It has been described tocomplicate usuallya bronchopulmonary infectionbut is currently uncommon in the era of antibiotics. Acute and massive purulent pericarditis has been rarely reported in children in association with human immunodeficiency virus (HIV) infection. This is a case of a10-year-old boy who presented with signs of sepsis and cardiac tamponade due to a massive staphylococcal purulent pericarditis complicating an unknown HIV infection.The child underwent pericardiectomy, intensive treatment, and survived this life-threatening disease.

Perioperative neonatal and paediatric blood transfusion

Paediatric patients undergoing surgical procedures commonly require some volume of blood or blood component replacement in the perioperative period. Paediatric patients undergoing major surgery associated with substantial blood loss should be evaluated pre-operatively. Pre-operative correction of anaemia may be done considering the age, plasma volume status, clinical status and comorbidities. Maximum allowable blood loss (MABL) for surgery must be calculated, and appropriate quantity of blood and blood components should be arranged. Intraoperative monitoring of blood loss should be done, and volume of transfusion should be calculated in a protocol based manner considering the volemia and the trigger threshold for transfusion for the patient and the MABL. Early haemostasis should be achieved by judicious administration of red blood cells, blood components and pharmacological agents.

Sinus histiocytosis with massive lymphadenopathy: a "massive" misnomer

Sinus histiocytosis with massive lymphadenopathy also known as Rosai-Dorfman disease is a rare, benign, histiocytic disorder of unknown origin characterized by lymphadenopathy. Since its original description by Rosai and Dorfman in 1969, small number of cases has been reported; hence no specific diagnostic criteria and treatment guidelines have been suggested. The purpose of this article is to present and discuss a case of Rosai Dorfman Syndrome in 4-year-old child diagnosed with the help of Fine Needle Aspiration Cytology. The swelling resolved over a period of 18 months without any recurrence in 2-year follow-up period. This case report highlights the role of Fine Needle Aspiration Cytology in the diagnosis of Rosai-Dorfman disease and the importance of regular follow ups using a careful wait and watch approach in its management. The report also briefly discusses the various dilemmas associated with its diagnosis and treatment.

No prosthetic management of massive and irreparable rotator cuff tears

A massive rotator cuff tear is not necessarily irreparable. Number of tendons involved, muscle-tendon unit quality, and decreased acromionhumeral distance (AHD) are as important as tear size in determining reparability of lesion. Massive and irreparable rotator cuff tears cannot be anatomically repaired to the bone and are a common source of pain and disability even in middle-aged patients. In these patients when conservative management has failed, it is possible to perform different surgical techniques. A functional repair can help to restore the horizontal force couple of the cuff on the humeral head and to increase the AHD. Debridement of irreparable tears and biceps tenotomy or tenodesis can have a role in low functional demand patients but results deteriorate over time. Recently, several commercially available tissue-engineered biological and synthetic scaffolds have been developed to augment rotator cuff repairs. The aim is to provide a mechanical improvement in case of poor quality tissue at time zero and give a support to have a better cuff healing. In selected cases, the scaffold can be used also to bridge tendon defect. Patients who not have pseudoparalysis, cuff tear arthropathy and with intact deltoid function can benefit from tendon transfers with satisfactory outcomes. These different procedures should be chosen for each patient with selected criteria and after a satisfactory explanation about the really possible expectation after surgery.

Delayed Presentation of a Congenital Cholesteatoma in a 64-year-old Man: Case Report and Review of the Literature

Introduction Congenital cholesteatomas of the temporal bone are epidermoid cysts of embryologic origin that result in progressive desquamation and trapping of squamous epithelium behind an intact tympanic membrane. They are benign, slowly progressive lesions that can be found in various areas of the temporal bone. We report a case of a patient with a massive cholesteatoma first detected at the age of 64 years, causing significant destruction of the mastoid and petrous temporal bones, and adjacent occipital bone.

Methods We reviewed the literature and a case report of a patient seen in our institution recently. The Medline database was used to search multiple terms including “congenital” and “cholesteatoma.”

Results The patient's congenital cholesteatoma was detected incidentally on a computed tomography scan when the patient's only symptoms were unilateral conductive hearing loss with a family history of hearing loss. It was subsequently successfully operated on with minimal postoperative complications.

Conclusions Congenital cholesteatomas of mastoid origin can often exist for many years in a subclinical state and develop into a massive size before causing symptoms. A high index of suspicion is necessary to detect congenital cholesteatomas in patients with unilateral conductive hearing loss who are otherwise asymptomatic and have a normal tympanic membrane.

Yellow nail syndrome presenting with postpartum massive pleural effusion

Yellow nail syndrome (YNS) is an uncommon clinical syndrome characterized by yellow-green discoloration of nails and recurrent respiratory tract lesions, pleural effusions and lymphedema. A 38-year-old woman was referred to the emergency complaining of chronic cough and increasing dyspnea within last 2 weeks. She had given birth 1 month ago. On examination, the patient exhibited dystrophic yellowish nails and mild peripheral lymphedema. A chest roentgenogram revealed a large right pleural effusion and a small left pleural effusion. YNS is a rare clinical entity but should be taken into consideration in patients with massive pleural effusions and persistent lymphedemas on the postpartum period.
