The monthly incidence of abusive head trauma, inflicted skeletal trauma, and unexplained skin lesion in children in six French university hospitals during the COVID-19 pandemic

INTRODUCTION

The COVID-19 pandemic was a stressful period. Lockdowns may have added to parental difficulty leading to an increase in violence. This study aimed to compare the monthly incidence of high suspicion of child physical abuse before and during the COVID-19 pandemic.

MATERIAL

We have retrospectively reviewed imaging examinations of children having a skeletal X-ray examination in six university hospitals with high suspicion of abusive head traumatism (AHT), inflicted skeletal trauma (IST) and unexplained skin lesions (USL) between March 2020 and June 2021 and compared with the similar period from 2018 to 2019. The monthly incidence of the different physical maltreatment was analyzed using a QuasiPoisson regression model.

RESULTS

We included 178 children (n = 127 boys, 71.3 %), 110 during the pandemic period, median age 5 months. AHT was diagnosed in 91 children, 55 had inflicted skeletal trauma (IST) and 46 had unexplained skin lesions (USL). Among the 91 patients with AHT, 86 had a subdural hematoma (95.6 %) and 40 had bridging veins thrombosis (44 %). The ophthalmological examination performed on 89 children (97.9 %) revealed retinal hemorrhages in 57 children (89.8 %). The incidence of AHT doubled during the months of COVID-19 lockdowns (rate ratio = 2; 95 % CI [1.1; 3.6], p = 0.03). No difference in monthly incidence was observed for IST and USL groups.

CONCLUSION

A significant increase in AHT was observed during the months with lockdowns and curfews during the COVID-19 pandemic. This highlights the need for developing a national strategy to prevent physical abuse in children in this context.

Early blood pressure management in hemorrhagic stroke: a meta-analysis

The aim of the present meta-analysis was to evaluate the outcomes and effects of different systolic blood pressure (SBP) lowering in patients with hemorrhagic stroke using data from randomized controlled trials. A total of 2592 records were identified for this meta-analysis. We finally included 8 studies (6119 patients; mean age 62.8 ± 13.0, 62.7% men). No evidence of heterogeneity between estimates (I² = 0% < 50%, P = 0.26), or publication bias in the funnel plots (P = 0.065, Egger statistical test) was detected. Death or major disability rates were similar between patients with intensive BP-lowering treatment (SBP < 140 mmHg) and those receiving guideline BP-lowering treatment (SBP < 180 mmHg). Intensive BP-lowering treatment may have a better functional outcome, but the results were not significantly different (log RR = - 0.03, 95% CI: - 0.09 to 0.02; P = 0.55). Intensive BP-lowering treatment tended to be associated with lower early hematoma growth compared with guideline treatment (log RR = - 0.24, 95% CI - 0.38, - 0.11; P < 0.001). Intensive BP-lowering helps reduce hematoma enlargement in the early stage of acute hemorrhagic stroke. However, this observation did not translate into functional outcomes. Further research is needed to clarify the specific scope and time of blood pressure reduction.

Should microbiological samples be taken routinely when performing revision surgery for post-surgical hematoma after hip or knee replacement? Retrospective study of 78 cases of surgically drained hematoma with a minimum follow-up of 2 years

INTRODUCTION

The relationship between the occurrence of a periprosthetic hip or knee joint infection, a post-surgical hematoma and the time to surgical revision, along with the need to take samples for microbiology analysis has not been clearly defined. This led us to perform a retrospective study to 1) define the rate of infected hematoma and subsequent infection after surgical revision for hematoma and 2) analyze in which time frame the hematoma was likely to be infected.

HYPOTHESIS

The more time elapsed before the postoperative hematoma is drained surgically after hip or knee replacement, the higher the hematoma infection rate and the late infection rate.

PATIENTS AND METHODS

Between 2013 and 2021, 78 patients (48 hip and 30 knee replacements) who had a postoperative hematoma without signs of infection upon draining were included in the study. Surgeons decided whether samples for microbiology were collected (33/78 patients (42%)). The data compiled consisted of the patient's demographics, the risk factors for infection, number of infected hematomas, number of subsequent infections at a minimum follow-up of 2 years, and the time to revision surgery (lavage).

RESULTS

Of the 27 samples collected from the hematoma during the first lavage, 12/27 (44%) were infected. Of the 51 that did not have samples collected initially, 6/51 (12%) had them collected during the second lavage; 5 were infected and 1 was sterile. Overall, 17/78 (22%) of the hematomas were infected. Conversely, there were no late infections at a mean follow-up of 3.8 years (min 2, max 8) after the hematoma was drained in any of the 78 patients. The median time to revision was 4 days (Q1 = 2, Q3 = 14) for non-infected hematomas that were drained surgically versus 15 days (Q1 = 9, Q3 = 20) for hematomas that were found to be infected (p = 0.005). No hematoma was infected when it was drained surgically within 72 hours post-arthroplasty (0/19 (0%)). The infection rate went up to 2/16 (12.5%) when it was drained 3 to 5 days later and 15/43 (35%) when it was drained after more than 5 days (p = 0.005). We believe this justifies collecting microbiology samples immediately when the hematoma is drained more than 72 hours after the joint replacement procedure. Diabetes was more prevalent in patients who had an infected hematoma (8/17 [47%] versus 7/61 [11.5%], p=0.005). The infection was due to a single bacterium in 65% of cases (11/17); S. epidermidis was found in 59% (10/17) of infections.

CONCLUSION

The occurrence of a hematoma after hip or knee replacement that requires surgical revision is associated with increased risk of infection, since the hematoma infection rate was 22%. Since hematomas drained within 72 hours are less likely to be infected, samples do not need to be collected for microbiology at that time. Conversely, any hematomas being drained surgically beyond this time point should be considered as infected, thus microbiology samples should be collected, and empirical postoperative antibiotic therapy initiated. Early revision may prevent the occurrence of late infections. The standard treatment of infected hematomas appears to resolve the infection at a minimum follow-up of 2 years.

Increased reliability of CT-imaging signs of bleeding into soft tissue in patients with COVID-19 for planning transarterial embolization

INTRODUCTION

Spontaneous bleeding into the soft tissues of the abdominal and thoracic wall is described as complication of anticoagulant therapy. Computed tomography (CT) allows to detect the presence of extravasation of the contrast agent into a hematoma, which is indicated as a sign of ongoing bleeding. Other specific CT signs of such coagulopathic bleeding have been described earlier.

AIM OF THE STUDY

To evaluate the significance of specific coagulopathic CT signs for predicting the dynamics of spontaneous bleeding into soft tissues in patients with COVID-19.

MATERIALS AND METHODS

A retrospective study included 60 patients with COVID-19 with spontaneous bleeding into soft tissues and extravasation of a contrast agent on CT. In addition to extravasation, a "hematocrit effect" was detected in 43 patients on CT. Of these, 39 had extravasation in the form of a "signal flare." All patients underwent transarterial catheter angiography (TCA). To assess the prognostic value of CT signs, the results of CT and TCA compared. The absence of extravasation on the TCA more often corresponded to stopped bleeding.

RESULTS

Extravasation on TCA found in 27 (45%) patients. The presence of the "hematocrit effect" or the combination of this sign with the phenomenon of a "signal flare" on CT (n = 43) led to more frequent confirmation of extravasation on TCA than in their absence (n = 17): 23.5% vs. 53.4% (p = 0.028).

CONCLUSION

The presence of a fluid level and the phenomenon of a "signal flare" on CT in the structure of spontaneous hematomas of the soft tissues of the abdominal and thoracic wall in COVID-19 patients more often corresponded to ongoing bleeding on the TCA. The absence of coagulopathic CT signs more often corresponded to stopped bleeding.

Relationship between hematoma-like tissue on the footprint and structural outcome of arthroscopic rotator cuff repair with a transosseous technique

Background

We have tried to create hematoma over the footprint site at the end of arthroscopic rotator cuff repair (ARCR) surgery, expecting to apply biochemical effects of the platelet-related factors. The purpose of this study was to investigate the presence of hematoma-like tissue (HLT) on postoperative magnetic resonance imaging, and to evaluate the relationship between the HLT and the structural outcomes of ARCR.

Materials and methods

Twenty-five patients were reviewed with a mean age at surgery of 69.8 years (range, 52-85 years). Postoperative magnetic resonance imaging was performed at 1 week, 6-8 weeks, and >6 months postoperatively. Structural outcomes for the repaired cuff and thickness of HLT were evaluated on coronal T2-weighted images. Signal intensity of HLT was evaluated on coronal T2-weighted fat-suppressed images as the ratio compared to supraspinatus tendon intensity (HLT/SSP ratio).

Results

Structural outcomes showed Sugaya type 1 in 12 shoulders, type 2 in 4, and type 3 in 9. HLT thickness was significantly thicker at 1 week and 6-8 weeks postoperatively in Sugaya type 1 patients than in type 3 patients (1 week; P = .014, 6-8 weeks; P < .001). HLT/SSP ratio gradually decreased (at 1 week; 1.9 ± 0.7, 6-8 weeks; 1.6 ± 0.6, >6 months; 1.2 ± 0.5), and differed significantly between >6 months and both 1 week and 6-8 weeks (P < .001 each).

Stroke-like manifestation of a spontaneous spinal epidural hematoma with spontaneous resolution: a case report

BACKGROUND

This case report presents the case of a man with no known coagulopathy or preceding trauma, who spontaneously developed a spinal epidural hematoma (SEH). This is an uncommon condition which can have variable presentations including hemiparesis mimicking stroke, resulting in the potential for misdiagnosis and inappropriate treatment.

CASE PRESENTATION

A 28-year-old Chinese male with no past medical history presented with sudden onset neck pain associated with bilateral upper limbs and right lower limb subjective numbness but intact motor function. He was discharged after adequate pain relief but re-attended the emergency department with right hemiparesis. A magnetic resonance imaging of his spine revealed an acute cervical spinal epidural hematoma at C5 and C6. While admitted, he had spontaneous improvement of his neurological function and was eventually managed conservatively.

CONCLUSIONS

SEH, although uncommon, can be a mimic of stroke and it is important to avoid misdiagnosis as it is a time critical diagnosis, and administration of thrombolysis or antiplatelets can lead to unfavourable outcomes. Having a high clinical suspicion can help to guide us in the choice of imaging and interpretation of subtle signs to reach the correct diagnosis in a timely manner. Further research is required to better understand the factors that would favour a conservative approach as opposed to surgical treatment.

The "SALPARE study" of spontaneous intracerebral hemorrhage: part 1

BACKGROUND

Spontaneous intracerebral hemorrhage (ICH) is a devastating type of stroke with a huge impact on patients and families. Expanded use of oral anticoagulants and ageing population might contribute to an epidemiological change. In view of these trends, we planned a study to obtain a contemporary picture and identify early prognostic factors to improve secondary prevention.

METHODS

This multicenter prospective cohort study included consecutive adult patients with non-traumatic ICH admitted to three academic Italian hospitals (Salerno, Padova, Reggio Emilia) over a 2-year period. Demographic characteristics, vascular risk profile, clinical data and main radiological characteristics were correlated to 90-day clinical outcome.

RESULTS

Out of 682 patients [mean age: 73 ± 14 years; 316 (46.3%) females] enrolled in this study, 40% died [86/180 (47.8%) in Salerno, 120/320 (37.5%) in Padova, 67/182 (36.8%) in Reggio Emilia; p < 0.05)] and 36% were severely disabled at 90 days. Several factors were associated with a higher risk of poor functional outcome such as antithrombotic drug use, hyperglycemia, previous cerebrovascular accident, low platelet count, and pontine/massive/intraventricular hemorrhage. However, at multivariate analysis only pre-ICH mRS score (OR 30.84), GCS score at presentation (OR 11.88), initial hematoma volume (OR 29.71), and NIHSS score at presentation (OR 25.89) were independent predictors of death and poor functional outcome.

CONCLUSION

Despite the heterogeneity among centers, this study on ICH has identified four simple prognostic factors that can independently predict patients outcome, stratify their risk, and guide their management.

The epidemiology and management of iliopsoas hematoma with femoral nerve palsy: A descriptive systematic review of 174 cases

INTRODUCTION

Iliopsoas hematoma with femoral nerve palsy is a rare phenomenon with no consensus treatment algorithm. The objective of this study was to perform a systematic review of all reported cases of femoral nerve palsy secondary to iliopsoas hematoma to better elucidate it's optimal treatment.

MATERIALS AND METHODS

Queries of the PubMed, Embase, and Cochrane databases were performed for reports available in English of femoral nerve palsy secondary to iliopsoas, psoas, or iliacus hematoma. 1491 articles were identified. After removal of duplicated publications and review of abstract titles via a majority reviewer consensus, 217 articles remained for consideration. Dedicated review of the remaining articles (including their reference sections) yielded 122 articles representing 174 distinct cases. Clinical data including patient age, sex, medical history, use of pharmacologic anticoagulation, sensory and motor examination at presentation and follow-up, hematoma etiology and location, time to intervention, and type of intervention were collected. Descriptive statistics were generated for each variable.

RESULTS

Femoral nerve palsy secondary to iliopsoas hematoma occurred at a mean age of 44.5 years old. A majority of patients (60%) were male, and a majority of hematomas (54%) occurred due to pharmacologic anticoagulation. Most hematomas (57%) were treated conservatively, and almost half (49%) - regardless of treatment modality - resulted in persistent motor deficits at final follow-up. A minority of patients treated surgically (34%) had residual motor deficit at final follow-up, while 66% of those treated medically had resultant motor deficits, although no direct statistical comparison was able to be performed.

DISCUSSION AND CONCLUSIONS

The disparate available data on iliopsoas hematoma with femoral nerve palsy precludes the completion of a true metanalysis, and therefore any conclusions on an optimal treatment algorithm. Based on review of the literature, small to moderate hematomas are often treated conservatively, while larger hematomas with progressive neurological symptoms are usually managed with a percutaneous decompression or surgery.

[Acquired inhibitory body hemophilia : A life-threatening reason for the tendency of hematoma-genesis.]

Here, we report a rare case of acquired hemophilia which was diagnosed months after development of spontaneous hematoma. Clinical symptoms, diagnosis, and treatment are briefly summarized. Acquired hemophilia is a rare potentially life-threatening acquired bleeding disorders which should be considered in patients with acquired spontaneous hematoma.

Traumatic hematoma-based pseudoaneurysm of the superficial temporal artery in a 7-year-old boy: a case report

The superficial temporal artery (STA), the terminal branch of the external carotid artery, is divided into the frontal (anterior) and parietal (posterior) branches. The frontal branch of the STA is located superficially on the anterior region of the scalp, making it especially susceptible to trauma. Here, we report a traumatic pseudoaneurysm of the STA in a 7-year-old boy who was injured in a minor car accident. A physical examination showed only a small bruise on the patient's forehead, and all vital signs were stable at the emergency room of our medical center. A facial computed tomography scan showed no significant findings. However, the boy later re-visited the hospital with slight swelling on the right forehead, and an ultrasonography scan revealed a hematoma near the right temporal artery. The resected hematoma (approximately 2 cm) was diagnosed as a traumatic pseudoaneurysm. Awareness of the possibility of a traumatic pseudoaneurysm in the STA may prevent a circumspect diagnosis in the future.

Dual-energy CT imaging of chronic subdural hematoma membranes: technical note

This technical note describes a novel dual-energy CT (DECT) protocol with iodine map reconstruction that will enable visualization of chronic subdural hematoma (CSDH) membranes. We describe the technique and discuss the potential implications for surgical management. The cohort included 36 patients with 50 hematomas. Enhancing external membrane was demonstrated in all the 50 hematomas, incomplete internal membrane in 13, and complete internal membrane in 23 hematomas. A spandrel sign at the transition zone that indicates partial or complete formation of internal membrane was demonstrated in 36 hematomas. KEY POINTS: • Iodine maps from 5-min delayed post-contrast DECT provide spectral contrast difference and facilitate segregation of chronic subdural hematoma membranes. • The ability to image the membranes helps in assessing the degree of organization of the hematoma by providing the information about the membrane thickness, volume, complexity of the membranes, and the proportion of the liquefied component within the hematoma before surgical procedures are undertaken. • Membrane visualization helps in the localization of the transition zone and extension of the membranes over the cerebral lobes helping in the determination of craniotomy location and size, during membranectomy.

Delayed-onset swelling around the implant after cochlear implantation: a series of 26 patients

PURPOSE

We aimed to clarify the clinical features of delayed-onset swelling around cochlear implants (CI), and to present our experience on how to avoid and address this problem.

METHODS

We performed a retrospective review of all CI cases at our institution between June 2001 and June 2020. Information on postoperative complications of swelling in the receiver area > 3 months after implantation were analyzed, and clinical data sheets were drawn.

RESULTS

Twenty-six of 1425 patients (1.82%) with an age at implantation ranging from 1 to 9 years experienced delayed-onset swelling around the implant. Swelling episodes occurred as early as 4 months, and as late as 178 months after implantation (median, 79.7 months). The predisposing factor in 12 cases was unclear, 7 cases were caused by trauma at the implantation site, 5 cases were without predisposing factors, and 2 cases were related to infection. We found the frequency of delayed-onset swelling after cochlear implantation with different incision was statistically insignificant (P = 0.423). Nineteen patients (73.1%) were cured after one treatment, and five patients (19.2%) relapsed. Follow-up examinations at least 18 months after surgery revealed that all patients experienced a complete recovery.

CONCLUSIONS

Delayed-onset swelling at the receiver site is a long term but not exactly uncommon complication after cochlear surgery and long-term follow-up is eagerly required. It can recur more than once, causing more complex treatment strategies in clinical practice. Conservative treatment first recommended, while needle aspiration should initially be considered in recurrent cases also when the effusion swelling is > 3 ml.

Endovascular management of rectus abdominis hematoma: A report of two cases

Nontraumatic spontaneous hematoma of the rectus abdominis is frequently related to anticoagulation therapy. In most cases, this condition is spontaneously self-limited or can be controlled with conservative therapy. Nevertheless, in some patients, despite early and adequate medical therapy, continuous development of the condition requires rapid and complete hemostasis. Currently, endovascular management by selective transarterial embolization of the bleeding vessel is the most common treatment option. We report 2 cases of endovascular management of rectus abdominis hematoma using a mixture of n-butylcyanoacrylate and lipiodol to embolize the bleeding point of the superior epigastric artery. Clinical symptoms improved without noticeable complications.

Effect of Drain Duration and Output on Perioperative Outcomes and Readmissions after Lumbar Spine Surgery

Study Design

Single-center retrospective cohort.

Purpose

To compare surgical outcomes of patients based on lumbar drain variables relating to output and duration.

Overview of Literature

The use of drains following lumbar spine surgery, specifically with respect to hospital readmission, postoperative hematoma, postoperative anemia, and surgical site infections, has been controversial.

Methods

Patients aged ≥18 years who underwent lumbar fusion with a postoperative drain between 2017 and 2020 were included and grouped based on hospital readmission status, last 8-hour drain output (<40 mL cutoff), or drain duration (2 days cutoff). Total output of all drains, total output of the primary drain, drain duration in days, drain output per day, last 8-hour output, penultimate 8-hour output, and last 8-hour delta (last 8-hour output subtracted by penultimate 8-hour output) were collected. Continuous and categorical data were compared between groups. Multivariate logistic regression analysis and receiver operating characteristic (ROC) analysis were performed to determine whether drain variables can predict hospital readmission, postoperative blood transfusions, and postoperative anemia. Alpha was 0.05.

Results

Our cohort consisted of 1,166 patients with 111 (9.5%) hospital readmissions. Results of regression analysis did not identify any of the drain variables as independent predictors of hospital readmission, postoperative blood transfusion, or postoperative anemia. ROC analysis demonstrated the drain variables to be poor predictors of hospital readmission, with the highest area under curve of 0.524 (drain duration), corresponding to a sensitivity of 61.3% and specificity of 49.9%.

Conclusions

Drain output or duration did not affect readmission rates following lumbar spine surgery.

Clinical outcomes after microsurgical resection of giant lateral ventricular meningiomas

Giant lateral ventricular meningiomas (LVMs), with the largest diameter of at least 5 cm, form a distinct subset. The incidence of giant LVMs is considered to be relatively low. Here, we evaluated clinical characteristics, and clinical outcomes after microsurgical resection, especially functional outcomes and morbidity of giant LVMs. We retrospectively reviewed 49 patients with LVMs, including 18 giant LVMs from 2012 to 2020. And we analyzed clinical, histopathological, surgical, and outcome data at our institution. Giant LVMs were most commonly present in the fourth decade of patients with the male-to-female ratio of 1:2. The most common subtypes were transitional and fibrous. Most lesions were resected via the temporal or parieto-occipital approach in our series. The median volume of blood loss was higher in the giant group (900 vs. 600 ml, p = 0.02). Meanwhile, the median length of hospital stay was prolonged for giant LVMs (20.5 vs. 16.0 days, p < 0.01). The proportion of discharged functional deterioration was higher in giant LVMs (38.9% vs. 6.5%, p = 0.02). However, there was no statistical significance between functional deterioration and tumor size at long-term follow-up (p = 0.28). Giant LVMs patients suffered from neurological and regional complications more commonly, particularly from a postoperative hematoma (4/18 vs. 1/31), and hydrocephalus (2/18 vs. 0/31). Patients with giant LVMs had a high incidence of immediate functional deterioration after microsurgery, and there was no difference in functional deterioration between the giant and non-giant LVMS during long-term follow-up. Microsurgery entails a higher complication rate in giant LVMs. We need to pay special attention to preventing postoperative hematoma and hydrocephalus.

Spontaneous spinal epidural hematoma in a pediatric hemophiliac

Background

Spontaneous spinal epidural hematomas (SSEH), unrelated to trauma, epidural anesthesia, or surgery, are rare in the pediatric population. Here, a 1-year-old male with hemophilia presented with a magnetic resonance (MR)-documented SSEH and was successfully treated with a C5-T10 right hemilaminectomy.

Case Description

A 1-year-old male with hemophilia presented with quadriparesis. The holo-spine magnetic resonance imaging with contrast showed a posterior cervicothoracic compressive epidural lesion extending from C3 to L1 consistent with an epidural hematoma. He underwent a C5 to T10 right-sided hemilaminectomy for clot removal, following which his motor deficits fully resolved. A literature review of SSEH attributed to hemophilia revealed that 28 of 38 cases were effectively treated conservatively, while only 10 cases warranted surgical decompression.

Conclusion

Select patients with SSEH attributed to hemophilia with severe MR-documented cord/cauda equina compromise and significant accompanying neurological deficits may require emergent surgical decompression.

Association between spontaneous intracranial epidural hematoma and craniofacial infections: A systematic literature review

Background

Spontaneous and nontraumatic epidural hematoma (SEDH) is a rare entity. Etiology is various, including vascular malformations of the dura mater, hemorrhagic tumors, and coagulation defects. The association between SEDH and craniofacial infections is rather unusual.

Methods

We performed a systematic review of the available literature using the PubMed, Cochrane Library, and Scopus research databases. Literature research was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We exclusively included studies reporting demographic and clinical data, published until October 31, 2022. We also report one case from our experience.

Results

A total of 18 scientific publications, corresponding to 19 patients, met the inclusion criteria for the qualitative and quantitative analysis. Patients were mostly adolescents, with a clear male predominance. SEDHs frequently occurred in the frontal area, usually near the site of the infection. Surgical evacuation was the treatment of choice with good postoperative outcomes. Endoscopy of the involved paranasal sinus should be achieved as soon as possible to remove the cause of the SEDH.

Conclusion

SEDH may occur as a rare and life-threatening complication of craniofacial infections; therefore, prompt recognition and treatment are mandatory.

Posterior fossa epidural hematoma: A 6-year management experience

Objective

Through this study, we sought to evaluate the management of posterior fossa extradural hematoma (PFEDH).

Methods

An observational study was conducted at the Neurosurgery Department of Lady Reading Hospital in Peshawar from January 2015 to December 2020. All patients who had a traumatic acute extradural hematoma (EDH) of the posterior fossa were included, irrespective of age and gender. The clinical predictors and outcomes were assessed, including the CT-scan findings and Glasgow Coma Scale (GCS) score.

Results

A total of 104 cases with posterior fossa extradural hematoma were identified from 1252 extradural hematoma patients admitted during the study period. The mean age of the enrolled patients was 18.17 ± 14.31 years. Most of the patients were male (65.39%) and belonged to the pediatric age group, i.e., < 15 years (60.6%). CT scan brain was done in all the cases for diagnosis. In 68.3% of cases, an associated occipital bone fracture was observed. Surgery was done in almost 71.2% of cases, and most of the patients experienced good recovery after surgery, as indicated by the GOS score. Linear regression model revealed that treatment (β=-0.20, p=0.038), time duration between surgery and trauma (β=0.43, p=0.000) and GCS category (β=-0.47, p=0.000) were significantly associated with PFEDH outcomes.

Conclusion

In conclusion, PFEDH was frequent among males and the pediatric age group. Serial CT brain is highly recommended in all suspected cases for early diagnosis.

Hematoma-Filled Pneumatocele after CT-Guided Percutaneous Transthoracic Needle Lung Biopsy: Two Case Reports

CT-guided percutaneous transthoracic needle biopsy (PTNB) plays a key role in the diagnosis of pulmonary abnormalities. Although the procedure is considered safe and effective, there exists a potential for complications, such as pneumothorax, hemorrhage, hemoptysis, air embolism, and tumor seeding. However, pneumatoceles after CT-guided PTNB have been rarely reported. Herein, we report two cases of pneumatoceles that developed immediately after PTNB for primary lung cancer. A pneumatocele filled with hematoma should be considered in cases with a newly developed nodule along the needle tract during short-term follow-up CT after PTNB.

Hematoma Following Shoulder Arthroplasty: Incidence, Management, and Outcomes

Background

A paucity of data regarding the implications of postoperative hematoma formation on outcomes after shoulder arthroplasty exists. Previous studies on major joint arthroplasty have associated postoperative hematoma formation with high rates of prosthetic joint infection (PJI) and reoperation.

Methods

A total of 6,421 shoulder arthroplasty cases were retrospectively reviewed from an institutional database (5,941 primary cases, 480 revision) between December 2008 and July 2017. Patients who developed a postoperative hematoma were identified through direct chart review. Cases with a history of shoulder infection treated with explant and antibiotic spacer placement were excluded. Demographics, surgical characteristics, treatment course, and outcomes were collected.

Results

Hematoma occurred in 105 (1.6%; 105/6421) cases within the first three postoperative weeks and was more common following revision (3.3%; 16/480) compared to primary cases (1.5 %; 89/5941; P=0.002). Overall, postoperative shoulder hematoma was successfully managed with nonoperative treatment in 87% of cases via observation (62%, 62/105) and aspiration (25%, 26/105). A total of 14 patients (0.22%, 14/6421) underwent reoperation for hematoma. Eight patients (7.6%, 8/105) that required reoperation for hematoma were diagnosed with PJI.

Conclusion

Postoperative hematoma is a complication of shoulder arthroplasty. While many postoperative hematomas can be managed without operative intervention, this analysis reiterates the association between hematoma formation and the development of PJI.

Retroperitoneal Hematoma as an Atypical Presentation of Choriocarcinoma: A Case Report

A 38-year-old female with an etonogestrel implant in place and history of previous ectopic pregnancy presented with acute abdominal pain and vaginal bleeding. She was found to have a beta-hCG of >12,000 mIU/mL and free fluid noted on a focused assessment with sonography in trauma exam. She underwent an emergent diagnostic laparoscopy due to the suspicion of a ruptured ectopic pregnancy. Findings at the time of surgery included a normal-appearing uterus and left fallopian tube, a surgically absent right fallopian tube and large volume hemoperitoneum with a rapidly expanding left retroperitoneal hematoma. A postoperative computerized tomography (CT) angiogram suggested active bleeding from a pseudoaneurysm of the left renal artery which was successfully embolized by interventional radiology. Biopsy confirmed gestational trophoblastic neoplasia (GTN) after metastases to the brain. In this report, we describe the details of this case of GTN with an atypical presentation.

Accelerated tibia fracture healing in traumatic brain injury in accordance with increased hematoma formation

BACKGROUND

Traumatic brain injury (TBI) has been known to accelerate bone healing. Many cells and molecules have been investigated but the exact mechanism is still unknown. The neuroinflammatory state of TBI has been reported recently. We aimed to investigate the effect of TBI on fracture healing in patients with tibia fractures and assess whether the factors associated with hematoma formation changed more significantly in the laboratory tests in the fractures accompanied with TBI.

METHODS

We retrospectively investigated patients who were surgically treated for tibia fractures and who showed secondary bone healing. Patients with and without TBI were divided for comparative analyses. Radiological parameters were time to callus formation and the largest callus ratio during follow-up. Preoperative levels of complete blood count and chemical battery on admission were measured in all patients. Subgroup division regarding age, gender, open fracture, concomitant fracture and severity of TBI were compared.

RESULTS

We included 48 patients with a mean age of 44.9 (range, 17-78), of whom 35 patients (72.9%) were male. There were 12 patients with TBI (Group 1) and 36 patients without TBI (Group 2). Group 1 showed shorter time to callus formation (P <  0.001), thicker callus ratio (P = 0.015), leukocytosis and lymphocytosis (P ≤ 0.028), and lower red blood cell counts (RBCs), hemoglobin, and hematocrit (P <  0.001). Aging and severity of TBI were correlated with time to callus formation and callus ratio (P ≤ 0.003) while gender, open fracture, and concomitant fracture were unremarkable.

CONCLUSION

Tibia fractures with TBI showed accelerated bone healing and superior measurements associated with hematoma formation (lymphocytes, RBCs, hemoglobin, hematocrit). Promoted fracture healing in TBI was correlated with the enhanced proinflammatory state.

A Single-Center 10-Year Experience of 180 Transmasculine Patients Undergoing Gender-Affirming Mastectomy While Continuing Masculinizing Hormone Replacement Therapy

BACKGROUND

Gender-affirming mastectomy is a fundamental step in the transition process of transmasculine patients following the initiation of hormone replacement therapy. Its perioperative management, however, remains underreported and controversial. In this study, a large series of mastectomies in transmen maintaining hormonal therapy is presented.

METHODS

Over a 10-year study period, a consecutive series of 180 transmasculine patients undergoing chest masculinizing surgery was evaluated. Demographical and surgical data were collected and analyzed for potential factors influencing outcome.

RESULTS

The overall rate of complications was 15.5%. Patients who underwent periareolar incision mastectomy were significantly more likely to develop any type of complication than patients with a sub-mammary incision (28.6% vs. 13.2%, p = 0.045). Hematoma was the most common reason for surgical revision. It occurred significantly more often among the periareolar group (21.4% vs. 7.9%, p = 0.041). Duration and type of hormonal therapy did not differ between patients with or without complications. In a multivariate regression analysis, smoking and type of incision were identified as significant predictors of the all-cause complication rate, whereas the influence of BMI and resection weight diminished after adjusting for confounding factors.

CONCLUSION

There is scarcity of information concerning the influence of perioperative hormonal therapy in patients undergoing chest wall masculinization. The observed complication rates-with special regard to hematoma-were comparable to current reports; yet further research is needed to profoundly evaluate this topic and provide evidence-based recommendations for the perioperative management of HRT of transmasculine patients.

SFE-AFCE-SFMN 2022 consensus on the management of thyroid nodules: Surgical treatment

The SFE-AFCE-SFMN 2022 consensus deals with the management of thyroid nodules, a condition that is a frequent reason for consultation in endocrinology. In more than 90% of cases, patients are euthyroid, with benign non-progressive nodules that do not warrant specific treatment. The clinician's objective is to detect malignant thyroid nodules at risk of recurrence and death, toxic nodules responsible for hyperthyroidism or compressive nodules warranting treatment. The diagnosis and treatment of thyroid nodules requires close collaboration between endocrinologists, nuclear medicine physicians and surgeons, but also involves other specialists. Therefore, this consensus statement was established jointly by 3 societies: the French Society of Endocrinology (SFE), French-speaking Association of Endocrine Surgery (AFCE) and French Society of Nuclear Medicine (SFMN); the various working groups included experts from other specialties (pathologists, radiologists, pediatricians, biologists, etc.). This section deals with the surgical management of thyroid nodules.

Does anticoagulation improve outcomes of microvascular free flap reconstruction following head and neck surgery: a systematic review and meta-analysis

The commonest cause of microvascular free flap failure is thrombosis at the anastomosis. Pharmacological antithrombotic therapies have been used to mitigate this risk, but they carry the risk of bleeding and haematoma formation. To justify any intervention, it is necessary to evaluate the benefits and balance of risks. This meta-analysis aims to quantify the value of systemic anticoagulation during head and neck free tissue reconstruction. We performed a systematic review on the impact of additional prophylactic antithrombotic therapy on head and neck (H&N) free tissue transfer (on top and above the use of low molecular weight heparin to prevent deep vein thrombosis). We carried a PRISMA-guided literature review, following registration with PROSPERO. All studies analysing the possible impact of prophylactic anticoagulants on free flap surgery in the head and neck were eligible. The primary outcome was perioperative free flap complications (perioperative thrombosis, partial or total free flap failure, thrombo-embolic events, or re-exploration of anastomosis). Secondary outcomes included haematoma formation or bleeding complications requiring further intervention. We identified eight eligible studies out of 454. These included 3531 free flaps for H&N reconstruction. None of the assessed interventions demonstrated a statistically significant improvement in free flap outcomes. Accumulative analysis of all anti-coagulated groups demonstrated an increased relative risk of free flap complications [RR 1.54 (0.73-3.23)] compared to control albeit not statistically significant (p = 0.25). Pooled analysis from the included studies showed that the prophylactic use of therapeutic doses of anticoagulants significantly (p = 0.003) increased the risk of haematoma and bleeding requiring intervention [RR 2.98 (1.47-6.07)], without reducing the risk of free flap failure. Additional anticoagulation does not reduce the incidence of free flap thrombosis and failure. Unfractionated heparin (UFH) consistently increased the risk of free flap complications. The use of additional anticoagulation as 'prophylaxis' in the perioperative setting, increases the risk of haematoma and bleeding.
