Physical examination a boon-racoon eyes in a child with neuroblastoma

Metastatic neuroblastoma often presents with prolonged fever, cytopenias and significant constitutional symptoms, before the abdominal mass is evident clinically. Clues like subcutaneous nodules and racoon eyes can help a clinician to suspect and evaluate appropriately to arrive at a timely diagnosis. We report a 3-year-old girl who had prolonged fever and constitutional symptoms for more than 2 weeks. On evaluation in outpatient visits, child was found to have cytopenia, hence was referred to our center for further management. Clinical examination revealed raccoon eyes with scalp nodules, hepatomegaly and abdominal mass predominantly over left lumbar area crossing over midline. On further investigations including radiological imaging and bone marrow biopsy child was diagnosed with metastatic neuroblastoma. Metastatic neuroblastoma often presents with prolonged fever, cytopenias and significant constitutional symptoms, before the abdominal mass is evident clinically. Clues like subcutaneous nodules and racoon eyes can help a clinician to suspect and evaluate appropriately to arrive at a timely diagnosis.

Clinical observation of free composite tissue flap transplantation in repairing head skin defect with artificial dural exposure infection / 中国医师杂志

Objective:To explore the effect of free transplantation of composite tissue flap from the anterior lateral aspect of the femur in repairing head skin defects with artificial dural exposure infection.Methods:A retrospective study was conducted on 13 patients admitted to the First Affiliated Hospital of Air Force Military Medical University from April 2018 to August 2020 with craniotomy complications, including craniotomy skin and soft tissue defects combined with artificial dural exposure and infection. After preoperative anti infection treatment, the neurosurgery department participated in debridement and removed the artificial dura mater as much as possible during the operation. A composite tissue flap carrying the fascia lata was designed for the anterior lateral aspect of the thigh, and the flap artery and vein were anastomosed with the superficial temporal artery and superficial temporal vein/middle temporal vein respectively. The defect of the dura mater was repaired with the fascia lata with blood supply. The flap was used to seal the wound, and the donor site was directly sutured or transplanted with autologous medium thick skin graft. The postoperative blood supply and survival of the flap, the presence of cerebrospinal fluid leakage, and the healing of the donor site were observed; The observation of dural integrity and postoperative effects of skull reconstruction using cranial magnetic resonance imaging was followed up.Results:Among the 13 patients in this group, 11 patients had their artificial dura mater completely removed, while 2 patients were not completely removed due to severe adhesion. Among them, 1 patient had a residual area of 0.8 cm×1 cm, and the other had 3 residual areas, with a maximum area of 0.5 cm×0.7 cm; All transplanted skin flaps survived, with 12 cases achieving primary healing and 1 case of partial wound rupture after suture removal, which healed after conservative dressing change; All patients had no cerebrospinal fluid leakage; There was one case of partial necrosis of the graft in the donor site, which healed after supplementing the graft; Thirteen patients underwent cranial magnetic resonance imaging at 3-6 months postoperatively, all of which showed intact dura mater; Among them, 8 patients have completed skull reconstruction surgery, and all of them have healed well after reconstruction, with a good appearance of the surgical area.Conclusions:For wounds with head skin defects and exposed artificial dura mater infection, free transplantation of the anterior lateral composite tissue flap carrying the fascia lata can effectively cover the wound and repair the dura mater defect, achieve good function and appearance, and create favorable conditions for later skull reconstruction.

Intravascular papillary endothelial hyperplasia: Olanzapine-induced vascular proliferation?

Intravascular papillary endothelial hyperplasia (Masson's tumor) is a reactive vascular lesion of obscure etiopathogenesis, often seen in the head and neck. Its presentation as a scalp swelling, however, is extremely uncommon. We describe the first report in an adult, being treated for bipolar illness. A young male presented with a right frontotemporal scalp swelling since 3 weeks. He was also being treated for bipolar illness with olanzapine. Examination revealed a soft, non-pulsatile swelling. After inconclusive aspiration results, a complete excision was performed. Histopathology revealed proliferating endothelial cells arranged as papillary fronds confined to vessel lumina, devoid of atypia, accompanied by thrombosed vessels facilitating a diagnosis of Masson's tumor. The patient is free of recurrence five months after surgery. Further studies on a possible effect of olanzapine on vascular proliferation in experimental in vivo and in vitro models would definitely aid in elucidating clinical relevance, if any.

Procedimentos estéticos com ênfase na queda capilar / Aesthetic procedures with emphasis on hair loss / Procedimientos estéticos con énfasis en la caída del cabello

A beleza está diretamente ligada ao aspecto dos cabelos, em todos os tempos e todas as culturas. O cabelo ao longo da vida é sujeito a vários tipos de mudanças, sejam elas naturais ou artificiais, conduzidas por uma vontade de mudar, muitas vezes, seja por representar uma nova fase, como também é símbolo de autocuidado, vaidade, sucesso, possuem significativa importância na aparência e autoestima das pessoas e, por isso, a queda capilar pode atingir a qualidade de vida do indivíduo. Neste sentido, o objetivo deste estudo foi avaliar procedimentos estéticos minimamente invasivos e não cirúrgicos com ênfase na queda capilar. Para tanto, foi realizada uma revisão bibliográfica integrativa, de caráter descritivo nas principais bases de dados em saúde: SciELO, Google Acadêmico, PubMed e livros de medicina, nos idiomas português, inglês e espanhol, considerando o período de 2007 a 2022. De acordo com o último censo da Sociedade Brasileira de Dermatologia, a queixa de alopecia está entre as dez mais frequentes nos consultórios dermatológicos. As doenças capilares mais importantes estão divididas em dois grupos, as cicatriciais quando a perda de cabelo é acompanhada por cicatrizes resultando em calvície permanente, e as não cicatriciais onde a calvície não é permanente levando a diminuição e o afinamento gradual do cabelo. A alopecia não cicatricial é a mais frequente e as mais comuns entre elas são a alopecia androgenética e o eflúvio telógeno. Muitos pacientes procuram tratamento para melhorar a aparência e a autoestima, que podem estar relacionados a quadros de ansiedade e depressão. Esses tratamentos devem ser individualizados, onde se deve avaliar as características individuais de cada paciente. Os tratamentos capilares estéticos podem contribuir de forma significativa para a redução da baixa autoestima, contribuindo para recuperação da autoconfiança através do crescimento capilar proporcionado pela estética. Sendo assim, conclui-se que os resultados coletados na revisão de literatura foram satisfatórios, de forma onde mostra que os medicamentos, suplementos e tratamentos estéticos na queda capilar vem evoluindo cada vez mais. Contudo, mais estudos acerca do assunto são necessários.

Beauty is directly linked to the appearance of hair, in all times and all cultures. Hair throughout life is subject to various types of changes, whether natural or artificial, driven by a desire to change, often because it represents a new phase, as it is also a symbol of self-care, vanity, success, they have significant importance in people's appearance and self-esteem and, therefore, hair loss can affect the individual's quality of life. In this sense, the objective of this study was to evaluate minimally invasive and non- surgical aesthetic procedures with an emphasis on hair loss. To this end, an integrative bibliographic review was carried out, of a descriptive nature, in the main health databases: SciELO, Google Scholar, PubMed and medical books, in Portuguese, English and Spanish, considering the period from 2007 to 2022. According to the latest census by the Brazilian Society of Dermatology, the complaint of alopecia is among the ten most frequent complaints in dermatological offices. The most important hair diseases are divided into two groups, scarring when hair loss is accompanied by scars resulting in permanent baldness, and non-scarring where baldness is not permanent leading to gradual thinning and thinning of the hair. Non-scarring alopecia is the most frequent and the most common among them are androgenetic alopecia and telogen effluvium. Many patients seek treatment to improve their appearance and self-esteem, which may be related to anxiety and depression. These treatments must be individualized, where the individual characteristics of each patient must be evaluated. Aesthetic hair treatments can contribute significantly to reducing low self-esteem, contributing to the recovery of self-confidence through hair growth provided by aesthetics. Therefore, it is concluded that the results collected in the literature review were satisfactory, in a way that shows that medicines, supplements and aesthetic treatments in hair loss have been evolving more and more. However, more studies on the subject are needed.

ObjectiveTo investigate the effect of hyperbaric oxygen combined with dynamic scalp acupuncture on motor function for stroke patients with hemiplegia, and compare the effect of dynamic scalp acupuncture inside or outside hyperbaric oxygen chamber. MethodsFrom January, 2021 to June, 2022, 72 stroke inpatients with hemiplegia in Fuyang People's Hospital were randomly divided into control group (n = 24), combination group 1 (n = 24) and combination group 2 (n = 24). All the patients received routine treatment, while the control group received dynamic scalp acupuncture, the combination group 1 received hyperbaric oxygen and dynamic scalp acupuncture outside the hyperbaric oxygen chamber, and the combination group 2 received hyperbaric oxygen and dynamic scalp acupuncture inside the hyperbaric oxygen chamber, for four weeks. They were assessed with National Institutes of Health Stroke Scale (NIHSS), modified Barthel Index (MBI), Berg Balance Scale (BBS), and Fugl-Meyer Assessment (FMA) before and after treatment. The rest pulse oximetry saturation (SpO2)，the lowest SpO2 (SpO2L) and the variation of SpO2 (ΔSpO2) were measured in the first and last treatment. ResultsThe scores of NHISS, MBI, BBS and FMA increased in all the groups after treatment (|t| > 7.681, P < 0.001), and they were more in both the combination group 1 and the combination group 2 than in the control group (P < 0.05). During the first and last treatment, the rest SpO2 and SpO2L increased in the combination group 2 compared with the control group and the combination group 1 (P < 0.05), while ΔSpO2 decreased (P < 0.05); and SpO2L increased in the combination group 1 compared with the control group during the last treatment. ConclusionThe combination of hyperbaric oxygen and dynamic scalp acupuncture can significantly improve motor function and oxygen-carrying capacity in stroke patients with hemiplegia.

Construction of an epileptic seizure prediction model using a semi-supervised method of generative adversarial and long short term memory network combined with Stockwell transform / 南方医科大学学报

OBJECTIVE@#To propose a semi-supervised epileptic seizure prediction model (ST-WGAN-GP-Bi-LSTM) to enhance the prediction performance by improving time-frequency analysis of electroencephalogram (EEG) signals, enhancing the stability of the unsupervised feature learning model and improving the design of back-end classifier.@*METHODS@#Stockwell transform (ST) of the epileptic EEG signals was performed to locate the time-frequency information by adaptive adjustment of the resolution and retaining the absolute phase to obtain the time-frequency inputs. When there was no overlap between the generated data distribution and the real EEG data distribution, to avoid failure of feature learning due to a constant JS divergence, Wasserstein GAN was used as a feature learning model, and the cost function based on EM distance and gradient penalty strategy was adopted to constrain the unsupervised training process to allow the generation of a high-order feature extractor. A temporal prediction model was finally constructed based on a bi-directional long short term memory network (Bi-LSTM), and the classification performance was improved by obtaining the temporal correlation between high-order time-frequency features. The CHB-MIT scalp EEG dataset was used to validate the proposed patient-specific seizure prediction method.@*RESULTS@#The AUC, sensitivity, and specificity of the proposed method reached 90.40%, 83.62%, and 86.69%, respectively. Compared with the existing semi-supervised methods, the propose method improved the original performance by 17.77%, 15.41%, and 53.66%. The performance of this method was comparable to that of a supervised prediction model based on CNN.@*CONCLUSION@#The utilization of ST, WGAN-GP, and Bi-LSTM effectively improves the prediction performance of the semi-supervised deep learning model, which can be used for optimization of unsupervised feature extraction in epileptic seizure prediction.

Association of microbiota with hair and scalp diseases / 中华皮肤科杂志

Objective:To investigate the clinical effect of free anterolateral thigh perforator flap(ALTPF) in reconstruction of temporal scalp defect after blood circulation reconstruction surgery for moyamoya disease.Methods:From May 2020 to July 2022, 7 patients with scalp defect after revascularisation of moyamoya disease were treated in Department of Hand and Foot Microsurgery, Henan Provincial People’s Hospital (People’s Hospital of Zhengzhou University). The patients were 4 males and 3 females, aged 33-59 years old, at 43 years old in average. There were 5 defects in left tempus and 2 in right tempus. The sizes of scalp defect were 4.5 cm × 5.5 cm-7.5 cm × 9.5 cm. Debridement and VSD management were primarily performed. After wounds were stabilised, ultrasound location of perforator vessels of ALTPFs was performed. Having confirmed that the perforator vessels were suitable for the surgical requirements, flap transfers were then performed. The descending branch of the lateral femoral circumflex artery was end-to-side anastomosed with the superficial temporal artery, and the descending branch of the lateral femoral circumflex vein was end-to-end anastomosed with the superficial temporal vein. Postoperative follow-up was conducted through outpatient clinic visits, telephone and WeChat reviews. Appearance, texture of ALTPFs and the flap donor sites were observed in follow-ups. Comparisons of the changes of nervous system before and after surgery were made. Cognitive function of the patients was assessed with the Mini Mental State Examination (MMSE), together with the Activities of Daily Living (ADL) .Results:All 7 flaps survived. One flap had vascular compromise 6 hours after surgery, and was rectified after surgical intervention. All the patients were included in the postoperative follow-up for 7-33 (average 19) months. All flaps had good appearance with soft texture. There was no obvious difference in colour comparing with the skin around the recipient region. The donor sites healed well without hypertrophic scar. Examinations of nervous system of the patients were found the same as that before surgery. Using Manual Muscle Testing (MMT), the average limb muscle strength of the patients was 4 before surgery and 4 after surgery, without change; Using the Ashworth assessment scale, the average preoperative and postoperative limb muscle tension in this group of patients was 1, without change; The Berg balance scale was used to evaluate the patient's balance function, with an average score of 42 before surgery and 42 after surgery, without any changes; There was no change in limb sensation before and after surgery; Using the MMSE, the average preoperative score and postoperative score of this group of patients were 25 points, without any change. Using the modified Barthel index scoring standard, the average preoperative score for this group of patients was 75 points, and the average postoperative score was 79 points, and the ADL of the patient had improved to various levels.Conclusion:Reconstruction of scalp defect with free ALTPF after revascularisation of moyamoya disease has obvious advantages, such as it closes the wound quickly, prevents infection and achieves a good appearance. This surgical procedure can produce a good clinical effect.

Efficacy and safety of acupuncture-moxibustion for cerebral palsy-induced speech impairment:a systematic review and meta-analysis / 针灸推拿医学（英文版）

Objective:To evaluate the efficacy and safety of acupuncture-moxibustion in the treatment of cerebral palsy-related speech impairment.Methods:A systematic literature search of 7 electronic databases was conducted between January 7,2000 and January 12,2021 to find randomized controlled trials(RCTs)examining the benefits of acupuncture-moxibustion combined with rehabilitation training to cerebral palsy-induced speech impairment.The included trials'quality was assessed using the Cochrane Reviewers'Handbook as a guide,and statistical analysis was carried out using the RevMan 5.3 software.Results:A total of 17 RCTs with 1238 subjects were finally recruited and analyzed.When acupuncture-moxibustion was combined with rehabilitation training,the results showed a considerable improvement in speech impairment compared with the rehabilitation training alone.The most commonly used points for the treatment of speech disorders are Baihui(GV20),Speech Area,Zhisanzhen[Shenting(GV24)and bilateral Benshen(GB13)],Niesanzhen[2 Cun above the ear tip as the first point,with 1.0 Cun anterior and posterior to the current point as the second and third points],and Sishenzhen[1.5 Cun anterior,posterior,and bilateral to Baihui(GV20)].Conclusion:Acupuncture-moxibustion has a stronger effect on children's development of receptive and expressive language,as well as the developmental quotient.Acupuncture-moxibustion in combination with rehabilitation training is not only more successful than the control treatment,but also safer and more dependable.Baihui(GV20),Speech Area,Zhisanzhen,Niesanzhen,and Sishenzhen are the most widely used points for speech impediment.

Brain removal through a posterior incision on the scalp of both ears / 解剖学报

Objective The traditional round incision or cross incision brain harvesting method can not meet the requirements of protecting the donor's remains. In this study, the method of brain removal through a posterior incision on the scalp of both ears was proposed, which effectively protected the donor's remains. Methods Adopting the incision 2. 0 cm above the external occipital protuberance to the most front edge of the auricle to obtain a complete brain. Results The incision did not involve the head and face skin, which was small and conducive to suture repair and reduce exudation. Conclusion The incision effectively protects the donor' s remains, and it will be conducive to the establishment and development of the brain bank.
