RESUMEN
BACKGROUND: Laser therapy is a treatment for infantile haemangiomas. The efficacy of laser therapy for red lesions is determined by visual evaluation; however, this assessment is inaccurate and lacks objectivity. OBJECTIVE: To scientifically validate the consistency between pre- and post-treatment visual assessment grades for infantile haemangioma treated with pulsed dye laser (PDL) and the values calculated from images obtained with Antera 3D™. METHODS: This study involved 81 cases of infantile haemangiomas treated with PDL alone from 2012 to 2015 and with Antera 3D™ images of the lesions. Using images obtained before treatment and 4-6 weeks after the last treatment, the lesions were rated using a visual four-step scale. Ratings were categorised as Poor/Fair/Good/Excellent by the degree of improvement in the red colour tone. The red colour ratio was calculated using the haemoglobin distribution in the lesion and surrounding skin, and the improvement difference and improvement rate were then obtained. The correlation between the improvement difference and improvement rate, and visual evaluation was statistically analysed. RESULTS: No serious adverse effects were observed, with an average of 4.3 treatments per patient; 60.1% of the patients achieved Good/Excellent results. There were statistically significant differences in the post-treatment red colour ratio and improvement ratio in each category after visual evaluation classification. The improvement rate and the four visual grades were statistically correlated. CONCLUSION: This study confirmed the scientific validity of visual evaluation and the evaluation criteria calculated from Antera 3D™. This method could objectively determine treatment effectiveness.

AIM: This study aims to explore the potential of Osmundacetone (OSC) as a new treatment for infantile hemangiomas (IH), the most common benign tumors in infancy. Currently, propranolol serves as the primary treatment for IH, but its effectiveness is limited, and it poses challenges of drug resistance and side effects. Therefore, there is a pressing need to identify alternative therapies for IH. METHODS: The effects of OSC on the proliferation and apoptosis of HemECs (endothelial cells from hemangiomas) were assessed using CCK-8 assay, colony formation assay, HOCHEST 33342 staining, and flow cytometry. Western blot analysis was performed to investigate OSC's influence on Caspases and angiogenesis-related proteins. Animal models were established using HemECs and BALB/c mice, and histological and immunohistochemical staining were conducted to evaluate the impact of OSC on mouse hemangiomas, VEGFR2, and MMP9 expression. RESULTS: OSC treatment significantly reduced HemECs' viability and colony-forming ability, while promoting apoptosis, as indicated by increased HOCHEST 33342 staining. OSC upregulated the protein expression of Bax, PARP, Caspase9, Caspase3, AIF, Cyto C, FADD, and Caspase8 in HemECs. In animal models, OSC treatment effectively reduced hemangioma size and improved histopathological changes. OSC also suppressed VEGFR2 and MMP9 expression while elevating Caspase3 levels in mouse hemangiomas. CONCLUSION: OSC demonstrated promising results in inhibiting HemECs' proliferation, inducing apoptosis, and ameliorating pathological changes in hemangiomas in mice. Moreover, it influenced the expression of crucial caspases and angiogenesis-related proteins. These findings suggest that OSC holds potential as a novel drug for clinical treatment of IH.

Circumscribed choroidal hemangioma is a rare vascular hamartoma of the choroid, presenting as a red-orange mass at the posterior pole on fundoscopic examination. Despite its benign origin, associated complications such as subretinal fluid, serous retinal detachment, retinoschisis and neovascular glaucoma may lead to serious visual impairment in more than half patients. Because of its similarity to amelanotic choroidal melanoma and choroidal metastasis, differential diagnosis is still challenging for specialists. Multimodal imaging such as ultrasonography, fluorescein angiography, indocyanine green angiography, optical coherence tomography, and optical coherence tomography angiography guides the clinician to the correct diagnosis and the proper follow-up. Treatment is indicated in symptomatic cases in order to resolve exudation and improve visual acuity. Treatment options include photocoagulation, transpupillary thermotherapy, radiation therapy, photodynamic therapy and anti-vascular endothelial growth factor therapy. Currently, photodynamic therapy is the treatment of choice due to its effectiveness and safety. The purpose of this review is to describe the latest knowledge in the etiopathogenesis of the circumscribed choroidal hemangioma, the most recent multimodal imaging findings, and the available treatment options.

Giant hepatic hemangiomas present a significant clinical challenge, and effective treatment options are warranted. This study aimed to assess the safety and feasibility of transarterial bleomycin-lipiodol embolization in patients with giant hepatic hemangiomas. A retrospective analysis was conducted on patients with giant hepatic hemangiomas (>5 cm). Transarterial chemoembolization (TACE) was performed using 7-20 cc of lipiodol mixed with 1500 IU of bleomycin. Safety outcomes, including post-embolization syndrome (PES), hepatic artery dissection, systemic complications, and access site complications, were evaluated. Radiation doses were also measured. Feasibility was assessed based on the achieved hemangioma coverage. Seventy-three patients (49 female, 24 male) with a mean age of 55.52 years were treated between December 2014 and April 2023. The average hospitalization duration was 3.82 days, and 97.3% of lesions were limited to one liver lobe. The average bleomycin dose per procedure was 1301.5625 IU, while the average lipiodol dose was 11.04 cc. The average radiation dose was 0.56 Gy. PES occurred after 45.7% of TACE procedures, with varying severity. Complications such as hepatic artery dissection (three cases), access site complications (two cases), and other complications (one case) were observed. No treatment-related mortality occurred. Hemangioma coverage exceeding 75% was achieved in 77.5% of cases. The study results suggest that transarterial bleomycin-lipiodol embolization is a safe and feasible treatment option for a heterogeneous group of patients with giant hepatic hemangiomas. This approach may hold promise in improving outcomes for patients with this challenging condition.

BACKGROUND: Facial Hemangiomas are often recommended to be removed exclusively in the operating room under general anesthesia, especially for children under the age of 4. Assumed parental and patient anxiety and possible blood loss pushes surgeons away from attempting excision under local anesthesia. METHODS: A review was conducted to assess the outcomes of children who underwent excision of facial hemangiomas under local anesthesia alone by 1 plastic surgeon with a minimum of 3 months follow-up. Complications and hemangioma recurrence were recorded. A survey was given 3 to 6 months after treatment to assess parental satisfaction, anxiety, and thought process about anesthesia. RESULTS: Eighteen children (9 males and 9 females) underwent in-office excision between 2020 and 2021. The mean age of this cohort was 12 months ( ranging 2-52 m). The average facial hemangioma size was 2.088 cm (ranging 1.0-3.2 cm). Ten patients experienced complete resolution (56%) at 12-month follow-up. There were no hospitalizations or cases of significant (>10 mL) blood loss, infection, dehiscence, hematoma, or scar hypertrophy. The average level of parental anxiety before the procedure was 3.3/10, and 1.6/10 after the procedure. Total 13/14 parents gave 4/4 ratings for satisfaction with the quality of care, team responsiveness, pain management, and management of expectations. CONCLUSIONS: Facial hemangioma removal under local anesthesia alone is a safe and feasible alternative treatment method for patients younger than 4 years of age.

BACKGROUND Patients commonly visit chiropractic clinics for treatment for low back pain, which is often due to injury or degenerative spinal conditions. Rarely, serious underlying pathology may be identified. This report describes a 68-year-old woman with a remote history of breast cancer presenting with low back pain to a chiropractic clinic in Hong Kong with imaging findings consistent with vertebral hemangioma and vertebral metastatic lesions. CASE REPORT A 68-year-old woman with a history of breast cancer status after chemotherapy and mastectomy 20 years prior presented to a chiropractor with an acute exacerbation of chronic low back pain with lower extremity paresthesia. She previously visited her general practitioner and underwent radiography, which supported diagnoses of degenerative lumbar spondylosis and hemangioma of the fifth lumbar vertebra. Given the patient's worsening status and previous cancer, the chiropractor ordered lumbar magnetic resonance imaging at the initial visit, consistent with multilevel spinal metastasis. The chiropractor referred the patient to an oncologist who performed positron emission tomography/computed tomography, which suggested breast cancer recurrence and metastasis. The greatest hypermetabolic activity was evident within the level of the suspected vertebral hemangioma, suggesting this finding which initially appeared innocuous on plain radiography contained underlying metastasis. CONCLUSIONS This case illustrates that when patients fail to respond to treatment for low back pain, clinical referral should be undertaken for investigations to identify possible serious underlying pathology.

INTRODUCTION: The lack of objectivity options for a specific individualized therapy might cause challenges in laser treatment. In other words, we need optimally determined laser parameters for less side effects. Generally, laser treatment procedures seem to be subjective. Then, the final evaluation of the patient needs for optimized better response with less laser sections and less side effects. Therefore, employing a reliable objective technique seems to be essential for better response with less laser treatment sessions and also less side effects. METHOD: In this research, UV-visible diffused reflection spectra from normal skin and a lesion were taken. We obtained the differences in absorption intensity at 575 nm, the wavelength corresponds to the absorption peak of blood oxyhemoglobin for normal skin and hemangioma. To calibrate the measurements, after using pulsed dye laser (PDL at 585 nm), the PDL treatment response of the patients were graded as "good (>50%), moderate(25%-50%), and poor (0%-25%)," by a specialist. Finally, patients were categorized based on the energy of the laser for the best treatment response to propose the recommended laser parameters. RESULTS: Based on the differences in the absorption peak hemangioma compare with normal skin, the energy density of PDL for a good treatment response of hemangioma was obtained at peak wavelength 575 nm. CONCLUSION: The analysis of optical reflection spectroscopy can assess the correlation of absorption peak differences of vascular lesions and normal skin. According to this data, it seems to be effective in optimizing lasers parameters for the hemangioma treatment.

PURPOSE: To determine the safety and efficacy of computed tomography (CT) fluoroscopy-guided percutaneous transhepatic sclerotherapy with a bleomycin/ethiodized oil emulsion for symptomatic giant hepatic hemangiomas. MATERIALS AND METHODS: The procedure was performed on 22 patients with symptomatic giant hepatic hemangiomas in an outpatient setting between 2018 and 2020. All patients were followed clinically and underwent contrast-enhanced magnetic resonance imaging after 1 month and again at a mean time of 15 months ± 2. Adverse events were classified according to the Common Terminology Criteria for Adverse Events (CTCAE, v5.0), in which a severe adverse event was defined as an adverse event with a grade of ≥3. The desired radiologic response (volume and index size) and improvement of pain intensity (visual analog scale [VAS]) and other symptoms were recorded as outcomes. RESULTS: Overall, patients showed a 36.4% ± 8.6 reduction in volume and a 14% ± 1.6 reduction in index size after 1 month, with P values of .002 and .001, respectively. The final follow-up volume and index size were 194.7 cm3 ± 25.8 and 77 mm ± 36, respectively. Moreover, a 53.0% ± 7 reduction in volume and 22% ± 3.7 reduction in index size during the final imaging were reported, with the P values of .001 and .001, respectively. Significant reductions in the mean pain intensity (90% of patients with lower VAS scores after intervention) and symptoms were reported. Four patients were classified as clinically unsuccessful, and were recommended further procedures for residual pain. CONCLUSIONS: CT fluoroscopy-guided transhepatic sclerotherapy is an effective, safe, and minimally invasive method to manage giant hepatic hemangiomas in an outpatient setting.

BACKGROUND Aggressive sacral hemangiomas are extremely rare benign tumors that can extend into the spinal canal, causing neurologic symptoms. Research on these tumors is limited given their rarity, and they have no agreed-upon treatment strategy. We report the first case of an aggressive sacral hemangioma responding well to conservative care, including manual therapies. CASE REPORT A 56-year-old Asian woman presented upon referral to a chiropractic office in Hong Kong with a 6-month exacerbation of chronic low back and lower extremity pain and weakness, requiring the use of a cane to walk. She had a known history of an aggressive sacral hemangioma with neural compromise and had been deemed ineligible for surgery and tumor ablation due to the large hemangioma size and risk of complications. Examination and imaging findings were consistent with compensatory myofascial pain, postural changes, sacral plexopathy, and lower cauda equina involvement. After coordinating with the neurosurgical team, the chiropractor carefully treated the patient with manual therapies, including thoracic spinal manipulation and instrument-assisted soft tissue manipulation, and mobility and strengthening exercises. She responded well, with symptom reduction lasting through 1-year follow-up, and no longer required the use of a cane. CONCLUSIONS This case illustrates the success of conservative chiropractic care for a patient with an aggressive sacral hemangioma not amenable to other treatments. As further research is needed on this topic, providers considering using manual therapies on patients with an aggressive sacral hemangioma should do so with caution and in collaboration with the patient's medical or surgical team.

Infantile hemangioma (IH) is the most common benign vascular tumor that occurs in infants and young children. Studies have shown laser therapy to reduce the proliferation of superficial IH and promote its regression, but the optimal timing for treatment has not been determined. Our study explores the timing and safety of 595-nm pulsed dye laser (PDL) treatment for early superficial IH. We retrospectively analyzed 180 cases of superficial IH treated with 595-nm PDL. Data was organized according to patient age at the first visit. Six months after the initial treatment, patients were evaluated using a grade IV classification method, and the clinical curative effect of each group was calculated. The number of laser treatments and the occurrence of adverse reactions were recorded simultaneously. The overall effective and cure rates were 98.3% and 84.4%, respectively, with no significant difference in rates between groups (p > 0.05). There was a statistically significant difference in the number of laser treatments among the age groups (p < 0.05). The average laser frequency: "0-2 months group" < "2-4 months group" < "4-6 months group." The overall incidence of adverse reactions was 11.1%, and 12 (6.7%) cases had short-term adverse reactions, with no statistically significant differences between groups (p > 0.05). Eight cases had long-term adverse reactions. This difference between groups was statistically significant (p < 0.05). Younger children (≤2 months of age) receiving 595-nm PDL treatment for IH require relatively fewer treatment times than other children (>2 months of age), have a shorter course of disease, experience better curative effect, and have fewer sequelae reactions.

The vertebral hemangioma (VH) and vertebrogenic pain syndromes of other etiologies are currently not a problem in terms of the choice of treatment method. However, the combination of these conditions makes the situation much more challenging. The question of the safety of physical treatment methods in these patients remains open, since there is no scientific evidence in this area. OBJECTIVE: To study the long-term results of electrotherapy, magnet therapy, lazer therapy, therapeutic exercises (TE), and therapeutic massage (in different combinations) in patients with degenerative-dystrophic processes of the spine and nonaggressive VH. MATERIAL AND METHODS: The study included 104 patients (75 females, 29 males) with degenerative-dystrophic processes of the spine and non-aggressive VH. The time between the treatment course and follow-up examination was 12 months. RESULTS: VHs remained unchanged in 86.5% of patients. An increase in size was noted in 13.5%. In no case did the VH become aggressive. After the TE course, the rate of VH size increase was 10.8%. The combination of TE with massage and electrotherapy (including a combination of all methods) resulted in an increase in VH size in 17.9, 20.0, 23.8% of cases, respectively. When magnet therapy was used, an increase in VH size was recorded significantly less frequently (p=0.021). No differences in the rate of VH size increase depending on sex, age (40-70 years), localization, and size were observed. In case of multiple VHs, the rate of growth was 23.1. CONCLUSION: A limitation of the study was the relatively small number of patients, which could, in some cases, affect the correctness of statistical data. Nevertheless, there is a general trend of the effect of physical treatments on the course of non-aggressive VH in patients with vertebrogenic pain syndromes. Such patients may be recommended low-frequency low-intensity electro- and magnet therapy, therapeutic back massage, and TE.

AIM: The article analyzes the results of treatment of children affected with lesions of blood vessels of the head and neck. The research is aimed at developing and implementing minimally invasive techniques to treat such children. MATERIAL AND METHODS: The study group comprised 4416 patients with hyperplasia of blood vessels (the so-called infantile and congenital hemangiomas) and 397 patients with blood vessel malformations, examined and treated from 1991 to 2020. RESULTS: The paper summarizes developed indications and the results of implementation of effective minimally invasive methods for the treatment of children with vascular lesions: radiofrequency thermal ablation and pulsed dye laser treatment of children with severe forms of arterio-venous malformation in their maxillofacial area and. The treatment is currently the golden standard that provides stable aesthetic results. CONCLUSION: The most optimal and preferred methods of vascular lesions treatment proved to be minimally invasive techniques that include: radiofrequency thermal ablation, interstitial laser coagulation, pulse phototherapy, sclerotherapy and systemic treatment of beta-blockers.

PURPOSE: To compare the efficacy of transpupillary thermotherapy (TTT), indocyanine green-enhanced TTT (ICG-TTT), and photodynamic therapy (PDT) in the management of circumscribed choroidal hemangioma (CCH) and to investigate the baseline clinical features effecting treatment outcomes METHODS: Retrospective review of clinical records of 60 eyes with CCH which underwent TTT (25), ICG-TTT (22), or PDT (13). Main study outcomes were 1) final visual acuity (VA) ≤20/200, 2) <2 Snellen lines VA increase, 3) persistent subretinal fluid (SRF), and 4) <20% decrease in tumor thickness. RESULTS: Multivariable factors associated with final VA ≤20/200 included longer duration of symptoms (p = 0.015), lower initial VA (p = 0.030), and presence of retinoschisis overlying the tumor (p = 0.047). Multivariable factors for <2 Snellen lines VA increase were longer duration of symptoms (p = 0.018) and previous failed treatment (p = 0.003). By multivariable analysis, the only significant factor for persistent SRF was the presence of retinoschisis (p = 0.001). Multivariable factors associated with a decrease in tumor thickness by <20% were smaller initial tumor thickness (p = 0.045) and presence of retinoschisis (p = 0.014). By Pearson Chi-Square/Fisher Exact Test, final VA ≤20/200 rates (48.0%, 13.6%, 30.8% respectively, p = 0.041) and VA improvement by <2 lines rates (64.0%, 27.3%, 38.5% respectively, p = 0.036) were significantly different between TTT, ICG-TTT, and PDT groups. However, by post hoc analysis, ICG-TTT yielded statistically better outcomes compared to TTT with respect to final visual acuity (VA) ≤20/200 (p = 0.012) and <2 Snellen lines VA increase (p = 0.012). CONCLUSIONS: Longer symptom duration, previous failed treatment, lower initial VA, and presence of retinoschisis were risk factors for worse visual outcomes. Eyes with retinoschisis displayed more SRF persistence after treatment. Smaller initial tumor thickness and presence of retinoschisis were risk factors for <20% decrease in tumor thickness.

Background Percutaneous sclerotherapy with bleomycin has been proven to have a potential benefit in the management of low-flow venous malformations. Liver hemangiomas are considered low-flow venous malformations. Thus, percutaneous sclerotherapy could potentially have a promising result in their management. Purpose To investigate the feasibility, efficacy, and safety of percutaneous sclerotherapy with bleomycin in the management of symptomatic giant liver hemangioma (GLH). Materials and Methods This single-institute prospective study was conducted between September 2018 and July 2020. Percutaneous sclerotherapy was performed using a mixture of bleomycin and ethiodized oil under guidance of US and fluoroscopy in participants with GLH who were experiencing related abdominal pain or fullness. Technical success was recorded. Change in symptom severity, according to visual analog scale (VAS), was considered the primary outcome of the study. Volume change, based on the lesion volume at CT, and complications, based on the classification of the Society of Interventional Radiology, were regarded as secondary outcomes. The primary and secondary outcomes were recorded 6 and 12 months after the procedure. Comparison was performed by using the Wilcoxon signed-rank test or paired t test. Results Twenty-eight participants (mean age, 45 years ± 9; 25 women) were evaluated. Technical success was 100%. The mean VAS score was 8.3 before the procedure, which decreased to 1.4 (84.7% reduction) and 1.5 (83.5% reduction) at 6- and 12-month follow-ups, respectively (P < .001 for both). All participants reported relief of symptoms (17 of 28 participants [61%] with complete relief; 11 [39%] with partial relief) at 12-month follow-up. Mean GLH volumes dropped from 856.3 cm3 to 309.8 cm3 (65.7% reduction) and 206.0 cm3 (76% reduction) at 6- and 12-month follow-ups, respectively (P < .001 for both). No major complications were detected. Conclusion Percutaneous sclerotherapy is a safe and feasible method with promising results in the treatment of patients with symptomatic giant liver hemangioma.

Infantile hemangioma (IH) is the most common benign vascular tumor resulting from the hyper-proliferation of vascular endothelial cells. In treatment of various tumors including IH, ß-elemene, a compound extracted from Rhizoma zedoariae, has been reported to have anti-tumor effect. However, the underlying mechanisms of ß-elemene in hemangioma have remained uninvestigated. In this presented study, functional analysis showed that low concentrations of ß-elemene promoted the proliferation, migration and tube formation of human hemangioma endothelial cells (HemECs), while high concentrations of ß-elemene produced inhibitory effects. Further, we also found that angiotensin-converting enzyme 2 (ACE2) expression was down-regulated at both mRNA and protein levels, while hypoxia-inducible factor-1 alpha (HIF-1-α) was up-regulated in infantile hemangiomas tissues and HemECs at both mRNA and protein levels. This result suggested that ACE2 and HIF-1-α play roles in IH. ACE2 expression was down-regulated with the treatment of ß-elemene at different dosage point. Interestingly, the expression of Vascular endothelial growth factor-A (VEGFA) increased with treatment of low concentrations of ß-elemene in HemECs, in contrary, the expression of VEGFA expression decreased with treatment of high concentrations of ß-elemene. Moreover, if the concentration of ß-elemene reached 40 µg/ml or higher, the expression of HIF-1-α decreased. Taken together, our data indicated that the different effects of ß-elemene on the proliferation, migration and angiogenesis of hemangioma at different concentrations: The ACE2 signaling pathway dominates with treatment of low concentrations of ß-elemene, stimulating the expression of downstream VEGFA to promote the angiogenesis of hemangioma; under the condition of high concentrations of ß-elemene, the HIF-1-α signaling pathway inhibits the expression of VEGFA and further inhibits the angiogenesis of hemangioma.

ABSTRACT CONTEXT: Various skin manifestations have been reported in coronavirus disease. It may be difficult to determine the etiology of these lesions in view of the increased frequency of handwashing during the pandemic, along with occurrences of irritant contact dermatitis and allergic contact dermatitis due to disinfectant use; usage of herbal medicine and supplements to strengthen the immune system; and urticarial or maculopapular drug eruptions due to COVID-19 treatment. The variety of associated skin manifestations seen with COVID-19 makes it challenging to identify virus-specific skin manifestations. Petechiae, purpura, acrocyanosis and necrotic and non-necrotic purpura, which can be considered as manifestations of vascular involvement on the skin, have been reported. CASE REPORT: Here, we report a case of eruptive cherry angiomas, which was thought to have developed due to COVID-19, with a papulovesicular rash on distal extremities that progressed over time to reticular purpura. CONCLUSION: The case presented had a papulovesicular rash at the onset, which evolved to retiform purpura, and eruptive cherry angiomas were observed. It should be kept in mind that dermatological signs may vary in patients with COVID-19.
