    牙龈过度生长,局部的或广义的,是口腔卫生维护不良的主要原因之一。使用激光切除生长应该是治疗的选择,因为激光有助于在治疗期间保持无血的手术部位,并在手术期间和之后提供更多的患者舒适度。激光器通常用于许多不同的应用,包括缩放,根规划,空腔准备,以及手术中软组织生长的切除。激光治疗提供优于传统治疗方法的许多益处。这些益处导致在各种牙科领域中越来越多地使用激光作为牙科治疗选择。在这个案例报告中,我们正在介绍使用激光切除局部牙龈生长的情况。激光手术术后愈合和口腔健康维护均满意。
    Gingival overgrowth, localized or generalized, is one of the leading causes of poor maintenance of oral hygiene. Excision of growth using laser should be the choice of treatment because laser helps maintain a blood-free surgical site during treatment and provides more patient comfort during and after the procedure. Lasers are commonly employed in many different applications, including scaling, root planning, cavity preparation, and excision of soft tissue growths in surgery. Laser therapy offers numerous benefits over traditional methods of treatment. These benefits have led to the growing use of lasers as dental treatment options in a variety of dental fields. In this case report, we are presenting a case of excision of localized gingival growth using a laser. Postoperative healing and maintenance of oral health were satisfied after laser surgery.

    牙龈增大可以被称为牙龈组织的尺寸增加。它可能源于炎症,由某些药物引起的,与广泛性疾病有关,恶性,或伪放大,根据其病因和发病机制。扩大可能很普遍,乳头状,或边缘,取决于位置。会影响病人的咀嚼,功能,美学,和心理健康。通过详细的历史来诊断病情及其根本原因是管理的支柱。诊断基于与一致性相关的仔细临床检查,纹理,和牙龈组织增大的颜色。一旦确诊,干预依赖于治疗与病情有关的致病因素。早期诊断和治疗,消除病因,严格的口腔卫生指导和定期随访可恢复美学和功能。本文介绍了一名31岁的女性患者的病例报告,该患者被送往口腔医学和放射科,主要抱怨牙龈肿胀,刷牙一个月时牙龈出血,自15天以来,颌骨左上背部区域的疼痛和牙齿松动。在彻底的临床检查中,口腔卫生说明与抗菌药物和镇痛药物一起给出,并进行了广泛的刮治和牙龈下刮治。在七天后的后续访问中,由于清除了斑块和结石等局部刺激物,并减少了牙龈肿大,因此炎症减少。这种情况下的结论是,临床医生应该彻底了解牙龈组织的正常和病理改变以及可能的病因。仔细检查,及时诊断,治疗是管理的主体。
    Gingival enlargement can be referred to as an increased size of the gingival tissues. It might have originated because of inflammation, induced by certain drugs, linked to generalized illness, malignant, or pseudo enlargement, based on its etiology and pathogenesis. Enlargements may be widespread, papillary, or marginal, depending on the location. It affects the patient\'s masticatory, functional, aesthetic, and psychological health. Diagnosing the condition and its underlying cause through a detailed history is the mainstay for management. Diagnosis is based on a careful clinical examination in relation to the consistency, texture, and color of enlarged gingival tissues. Once diagnosed, the intervention relies on treating the causative factor involved in the condition. Early diagnosis and treatment with the elimination of the etiologic factor along with strict oral hygiene instructions and regular follow-up results in the restoration of aesthetics and function. This article presents a case report of a female patient aged 31 years who presented to the Oral Medicine and Radiology Department with chief complaints of swollen gums, bleeding gums while brushing for one month, and pain and loosening of teeth in the upper left back region of the jaw since 15 days. On thorough clinical examination, oral hygiene instructions were given along with antimicrobials and analgesic medications, and extensive scaling and sub-gingival curettage were done. On the follow-up visit after seven days, there was reduced inflammation due to the removal of local irritants like plaque and calculus and reduced gingival enlargement. The takeaway message from this case is that clinicians should be thoroughly acquainted with the normal and pathologic alterations of the gingival tissues and possible etiologic factors for it. Careful examination, prompt diagnosis, and treatment form the mainstay of management.

    目的:肾上腺小偶发瘤(AI)治疗的不确定性在实际临床实践中仍然是一个挑战。考虑到缺乏与肿瘤增大有关的危险因素的知识,本研究的目的是确定肾上腺偶发瘤(AI)随访期间形态学改变的危险因素.
    方法:我们回顾性评估了人口学,临床,153个AI的放射和生化参数(2007-2021年)。排除组织学诊断为转移或嗜铬细胞瘤的患者。为了检测肿瘤增大的危险因素,如果与AI相关的疾病的患病率高于2%,则将其包括在内。将患者分为两组(A:放射学稳定性;B:定义为主要直径>5mm/年的肿瘤扩大)。
    结果:A组:89.5%,B组:10.5%,平均随访38.6±6.9个月(范围6-240)。肿瘤肿大发生在随访36个月内。B组体重较高(p<0.03),硫酸脱氢表雄酮(DHEAS)(p<0.05)和直接肾素浓度(DRC)(p<0.04)均高于A组,而醛固酮水平较低;此外,考虑到合并症,B组青光眼和血糖异常(两者p<0.01)患病率较高。受青光眼影响的患者,心房颤动,与未受影响的患者相比,血糖异常患者的无维度变化生存率较低.
    结论:青光眼可能是AI增大的新危险因素。如果微妙的不可检测的皮质醇过度分泌有作用是进一步研究的主题。
    OBJECTIVE: The uncertainty on the management of small adrenal incidentalomas (AIs) still represents a challenge in real clinical practice. Considering the lack of knowledge on risk factors implicated in tumour enlargement, the aim of this study was to identify risk factors for morphological changes during follow-up of adrenal incidentalomas (AIs).
    METHODS: We retrospectively evaluated demographic, clinical, radiological and biochemical parameters of 153 AIs (2007-2021). Patients with histological diagnosis of metastases or pheochromocytoma were excluded. To detect risk factors for tumor enlargement, diseases associated with AIs were included if their prevalence was higher than 2%. Patients were divided into two groups (A: radiological stability; B: tumor enlargement defined as > 5 mm/year in the main diameter).
    RESULTS: Group A: 89.5% and group B: 10.5%, mean follow-up 38.6 ± 6.9 months (range 6-240). Tumor enlargement when occurred was within 36 months of follow-up. In group B high body weight (p < 0.03), dehydroepiandrosterone sulfate (DHEAS) (p < 0.05) and direct renin concentration (DRC) (p < 0.04) were higher than group A, while aldosterone levels were lower; moreover, considering comorbidities, glaucoma and dysglycemia (p < 0.01 for both) had higher prevalence in group B. Glaucoma and dysglycemia were independent predictors of enlargement. Patients affected by glaucoma, atrial fibrillation, dysglycemia had a lower dimensional change-free survival than non-affected.
    CONCLUSIONS: Glaucoma might be a novel risk factor for AI enlargement. If subtle undetectable cortisol hypersecretion has a role is a topic for further research.

    一名46岁的妇女因心悸和劳力性呼吸困难3个月的病史而入院。她在很小的时候就有成功怀孕的历史。胸部X光片显示“葫芦”构型。超声心动图发现大的房间隔缺损,疑似肺静脉异常。心脏CT显示心上完全肺静脉回流异常,据此,所有的肺静脉都流入垂直静脉,最后,上腔静脉.心导管插入术与肺静脉异位引流一致,无肺动脉高压。最后,她接受了成功的手术修复,出院前无症状。
    A 46-year-old woman was admitted to the cardiovascular department because of a 3-month history of palpitations and exertional dyspnea. She had a history of a successful pregnancy at a very young age. The chest radiograph presented a \"calabash\" configuration. Echocardiogram discovered a large atrial septal defect with a suspected pulmonary vein abnormality. Cardiac CT revealed supracardiac total anomalous pulmonary venous return, whereby, all the pulmonary veins drain into a vertical vein and, finally, to the superior vena cava. Cardiac catheterization was consistent with anomalous pulmonary venous drainage without pulmonary hypertension. Finally, she underwent a successful surgical repair and appeared asymptomatic before her discharge.

    Galactocele is cystic dilatation of the mammary gland, which contains milk. Galactocele is usually presented as a painless breast enlargement with a fluctuant, soft, mobile, and non-tender mass in the breast. It is a rare disorder in the male pediatric age group, with only 31 cases reported in the literature. In this article, we present another case of unilateral galactocele in a 14-month-old male infant. Ultrasound imaging confirmed a simple cystic hypoechoic mass in the right breast, and needle aspiration was performed before surgery as a diagnostic procedure (a 1-cc extract revealed a milky-colored fluid).

    Thebesian veins in the heart are subendocardial venoluminal channels and are usually less than 0.5 mm in diameter. The system of TV either opens a venous (venoluminal) or an arterial (arterioluminal) channel directly into the lumen of the cardiac chambers or via some intervening spaces (venosinusoidal/ arteriosinusoidal) termed as sinusoids. Enlarged thebesian veins are reported in patients with congenital heart disease and usually, multiple veins are enlarged. Very few reports of such abnormal enlargement are there in the absence of congenital heart disease, but in all such cases, they are multiple and in association with coronary artery microfistule. We report a very rare case of a singular thebesian vein in the right atrium, which was abnormally enlarged. It is important to recognize because it can be confused with other cardiac structures like coronary sinus during diagnostic or therapeutic catheterization and can lead to cardiac injury and complications if it is attempted to cannulate it or pass the guidewires.

    目的阐明椎动脉夹层动脉瘤(VADAs)急性期扩大的发生率及扩大的相关因素。
    在115例未经历蛛网膜下腔出血的单侧颅内椎动脉夹层患者中,64例椎动脉夹层珍珠征(无狭窄的VADA)参与了研究。我们进行了初始磁共振成像以诊断VADA,随后进行了磁共振成像以评估VADA扩大。使用T1加权三维涡轮自旋回波成像确认了高强度壁内信号的存在。通过磁共振血管造影术评估初始和后续检查之间的VADA扩大情况,并将其定义为终点。我们使用Kaplan-Meier曲线分析研究了VADA的扩大率。自变量确定后,Cox比例风险模型应用于多变量分析,以确定与VADA扩大显著相关的因素.
    64名患者(平均年龄,55.7±13.0岁;44名男性和20名女性),15展示了VADA扩大。Kaplan-Meier曲线分析表明,在初始磁共振成像后30天检测到24.8%的VADA扩大。Cox比例风险模型显示,年轻年龄(风险比0.953,P=0.043)和高信号的存在(风险比2.841,P=0.033)与VADA增大显着相关。
    在初次检查后第30天,VADAs扩大了约25%。较年轻的年龄和高信号的存在与VADA扩大显着相关。
    To elucidate the incidence rate of enlargement of vertebral artery dissecting aneurysms (VADAs) during the acute phase and factors associated with enlargement.
    Of 115 patients with unilateral intracranial vertebral artery dissection who did not experience subarachnoid hemorrhage, 64 with the pearl sign of vertebral artery dissection (VADA without stenosis) participated in the study. We performed initial magnetic resonance imaging to diagnose VADA and subsequent magnetic resonance imaging to evaluate VADA enlargement. The presence of a hyperintense intramural signal was confirmed using T1-weighted three-dimensional turbo spin-echo imaging. Enlargement of VADAs between the initial and subsequent examinations was evaluated via magnetic resonance angiography and defined as the end point. We studied the rate of VADA enlargement using Kaplan-Meier curve analysis. After independent variables were determined, the Cox proportional hazards model was applied in multivariable analysis to identify the factors significantly associated with VADA enlargement.
    Of 64 patients (mean age, 55.7 ± 13.0 years; 44 men and 20 women), 15 exhibited VADA enlargement. Kaplan-Meier curve analysis indicated that 24.8% of VADA enlargements were detected 30 days after initial magnetic resonance imaging. The Cox proportional hazards model revealed that young age (hazard ratio 0.953, P = 0.043) and the presence of hyperintense intramural signal (hazard ratio 2.841, P = 0.033) were significantly associated with VADA enlargement.
    VADAs enlarged by approximately 25% until day 30 after the initial examination. Younger age and the presence of hyperintense intramural signal were significantly associated with VADA enlargement.

    程度,严重程度,和放射学发现的婴儿卵巢生长的遗传综合征的胰岛素抵抗尚未得到充分描述。我们报道了一例罕见的先天性胰岛素抵抗综合征女婴可逆性卵巢大量增大的病例。考虑到临床上较不严重的病程,可能是Rabson-Mendenhall综合征。该患者因先天性胰岛素抵抗而出现新生儿糖尿病并伴有高胰岛素血症和高血糖。她出现了严重的双侧卵巢增大,在4个月大时达到顶峰,随后,在使用胰岛素增敏药物治疗后,卵巢大小逐渐减小,高胰岛素血症得到改善。据推测,卵巢增大是胰岛素以不依赖促性腺激素的机制起作用的营养作用所致。先天性胰岛素抵抗中的高胰岛素血症也可导致其他器官的肥大。了解先天性胰岛素抵抗综合征背景下卵巢大量增大背后的病理生理学可以帮助指导适当的治疗。
    The extent, severity, and radiological findings of ovarian growth in infants with genetic syndromes of insulin resistance have not been fully described. We report a rare case of reversible massive ovarian enlargement in a female infant with a congenital insulin resistance syndrome, likely Rabson-Mendenhall syndrome given the less clinically severe course. The patient presented with neonatal diabetes with hyperinsulinemia and hyperglycemia due to congenital insulin resistance. She developed increasing severe bilateral ovarian enlargement which peaked at 4 months of age, followed by gradual decrease in size of the ovaries following treatment with insulin-sensitizing drugs and improved hyperinsulinemia. The ovarian enlargement is postulated to be secondary to the trophic effects of insulin acting in a gonadotropin-independent mechanism. Hyperinsulinemia in congenital insulin resistance can also result in hypertrophy of other organs. Understanding the pathophysiology behind massive ovarian enlargement in the setting of congenital insulin resistance syndromes can help guide appropriate therapy.

    BACKGROUND: An accessory spleen (AS), a common condition, is usually located in the hilar region of the spleen. ASs are not often large; however, after splenectomy, the initially inactive AS may become reactive and hypertrophic. Therefore, an AS can be misdiagnosed as a neoplastic tumor and removed unnecessarily. An undiagnosed abdominal mass located in the spleen site in a patient who has had a splenectomy must be managed carefully. Computed tomography (CT) scanning and magnetic resonance imaging (MRI) may provide useful information for the diagnosis, preventing unnecessary surgery.
    METHODS: Herein, we report the case of a 38-year-old female with an enlargement of AS after splenectomy that was misdiagnosed as a primary tumor of the pancreas and managed by a nonessential surgery.
    CONCLUSIONS: An AS should be added to the differential diagnosis of a pancreatic tail tumor for patients with prior splenectomy in order to avoid nonessential surgery to ensure the patient\'s safety.

    Nanopores in solid state membranes are a tool able to probe nanofluidic phenomena or can act as a single molecular sensor. They also have diverse applications in filtration, desalination, or osmotic power generation. Many of these applications involve chemical, or hydrostatic pressure differences which act on both the supporting membrane, and the ion transport through the pore. By using pressure differences between the sides of the membrane and an alternating current approach to probe ion transport, we investigate two distinct physical phenomena: the elastic deformation of the membrane through the measurement of strain at the nanopore, and the growth of ionic current rectification with pressure due to pore entrance effects. These measurements are a significant step toward the understanding of the role of elastic membrane deformation or fluid flow on linear and nonlinear transport properties of nanopores.
