OBJECTIVES: About 90% of oral cancers are oral squamous cell carcinomas (OSCC) whose appropriate treatment requires early diagnosis, based on knowledge about biomarkers which are expressed during the complex process of carcinogenesis. Growth differentiation factor-15 (GDF-15) has been considered an important serum and immunohistochemical marker in several cancers. Saliva has several advantages as a diagnostic biofluid. This research intends to evaluate the salivary GDF-15 levels in oral leukoplakia (OL) and in OSCC. MATERIALS AND METHODS: We estimated and compared levels of salivary GDF-15 in cases of OL, OSCC, and healthy controls. Study groups comprised 30 cases each of OL and OSCC. Control group comprised 30 healthy individuals. Saliva samples were assessed using the enzyme-Linked immunosorbent assay for GDF-15 levels. RESULTS: Salivary GDF-15 levels showed a gradual increase from healthy volunteers to cases of OL and highest GDF-15 levels were noted in OSCC group. Increase in concentration of GDF-15 was also noted with increasing grades of OSCC. CONCLUSION: Increased level of GDF-15 in premalignant cases reflects its antitumorigenic role, whereas its expression in later stages of OSCC demonstrates its protumorigenic role. The regulatory mechanism associated with GDF-15 may help in developing some novel therapeutic strategies based on its expression.
目的:约 90% 的口腔癌是口腔鳞状细胞癌(OSCC):约 90% 的口腔癌是口腔鳞状细胞癌 (OSCC),其适当的治疗需要早期诊断,而早期诊断的基础是了解在复杂的癌变过程中表达的生物标志物。生长分化因子-15(GDF-15)被认为是多种癌症的重要血清和免疫组化标志物。唾液作为一种诊断生物流体具有多种优势。本研究旨在评估口腔白斑(OL)和 OSCC 的唾液 GDF-15 水平。材料与方法:我们估算并比较了 OL、OSCC 和健康对照组唾液 GDF-15 的水平。研究组包括 OL 和 OSCC 病例各 30 例。对照组包括 30 名健康人。采用酶联免疫吸附法对唾液样本进行 GDF-15 含量评估。结果:从健康志愿者到OL病例,唾液中的GDF-15水平呈逐渐上升趋势,OSCC组的GDF-15水平最高。随着 OSCC 级别的增加,GDF-15 的浓度也在增加。结论:恶性肿瘤前期病例中 GDF-15 水平的升高反映了其抗肿瘤作用,而其在 OSCC 晚期的表达则表明其具有原发肿瘤作用。与 GDF-15 相关的调控机制可能有助于根据其表达情况开发一些新型治疗策略。

BACKGROUND: DNA fingerprinting is a Special technique used to determine the probable identity of a person based on the nucleotide sequences of certain regions of Plant DNA that are unique to individuals. AIMS AND OBJECTIVES: In this study, the random amplified polymorphic deoxyribonucleic acid (RAPD) technique was employed for the determination of the components in Ayurvedic herbal medicine. The RAPD approach is appealing to a large number of scientists since it may be implemented in a variety of settings with little effort. Most importantly, RAPD analysis does not require any cloning, sequencing, or other molecular characterization of the genome to extract a large number of genetic markers from a small amount of deoxyribonucleic acid (DNA). MATERIALS AND METHODS: Fresh leaves of the Thevetia peruviana (Pers.) Roxb plants were gathered in the month of June in the surroundings of Solapur. RESULTS: We used OPAB11, OPT12, OPQ15, and OPC104 decamer primers to conduct an RAPD study that measures genetic variation at random. Pure and RNA free high molecular weight DNA was extracted from the leaves. CONCLUSION: The DNA was amplified with repeat primers and 4 polymerase chain reaction primers, and then analyzed on agarose gels. Other wild T. peruviana species might be easier to track down with this method.
背景:DNA 指纹识别是一种特殊技术,用于根据植物 DNA 某些区域的核苷酸序列确定个人的可能身份。目的和目标:本研究采用随机扩增多态脱氧核糖核酸(RAPD)技术来确定阿育吠陀草药中的成分。随机扩增多态脱氧核糖核酸(RAPD)方法对许多科学家来说都很有吸引力,因为它可以在各种环境下使用,而且不费吹灰之力。最重要的是,RAPD 分析不需要对基因组进行任何克隆、测序或其他分子鉴定,就能从少量脱氧核糖核酸(DNA)中提取大量遗传标记。材料与方法:我们于 6 月份在索拉普尔周边地区采集了 Thevetia peruviana (Pers.) Roxb 植物的新鲜叶片。结果:我们使用 OPAB11、OPT12、OPQ15 和 OPC104 十聚体引物进行了 RAPD 研究,随机测量遗传变异。从叶片中提取了纯净且不含 RNA 的高分子量 DNA。结论:使用重复引物和 4 种聚合酶链反应引物扩增 DNA,然后在琼脂糖凝胶上进行分析。用这种方法可能更容易追踪到其他野生 T. peruviana 物种。

Humanitarian emergencies such as man-made conflicts tend to influence and impact every aspect of human lives, including medical education. Humanitarian emergencies accounts for far-reaching consequences in the domain of medical education, including disruption of educational infrastructure (viz. medical school and training facilities) that significantly hampers the delivery of medical education. There is an immense need to plan and prepare for these humanitarian emergencies and thereby implement appropriate measures to ensure that delivery of medical education is not disturbed. To conclude, humanitarian emergencies have become quite common in today's era. However, as the impact of these emergencies on medical education is multi-fold, there is an immense need to address the problem. In-fact, the need of the hour is to plan and implement a multi-pronged approach to ensure that despite the challenges posed by humanitarian emergencies, we are well-equipped to ensure medical education delivery.
人为冲突等人道主义紧急情况往往会影响人类生活的方方面面,包括医学教育。人道主义紧急情况给医学教育领域带来了深远的影响,包括教育基础设施(即医学院和培训设施)遭到破坏,严重阻碍了医学教育的开展。我们亟需对这些人道主义紧急情况进行规划和准备,从而采取适当措施,确保医学教育的开展不受干扰。总之,人道主义紧急情况在当今时代已相当普遍。然而,由于这些紧急情况对医学教育的影响是多方面的,因此亟需解决这一问题。事实上,当务之急是规划和实施多管齐下的方法,以确保尽管人道主义紧急情况带来了挑战,但我们仍有能力确保医学教育的开展。

BACKGROUND: Palate has been a topic of interest regarding sex determination from human skeletal remains in physical anthropology. Palatal index (PI) is an important parameter for the sex determination of deceased individuals with unknown identity. AIM: The study aimed to determine and compare PI, clinically and radiographically, and evaluate its role in sexual dimorphism in the Central Indian population. MATERIALS AND METHODS: This study was conducted on 392 participants, in the department of anatomy and dentistry of a premium medical college in India. Maxillary casts were used for clinical measurement. Posteroanterior and lateral cephalogram (Ceph) were used for the radiographic method. Palatal length (PL) and palatal breadth (PB) were measured. PI was calculated as PB/PL × 100. Data were analyzed using unpaired Student's t-test. RESULTS: Participants belonged to the age group of 41–50 years (31.63%), 51–60 years (27.04%), and 18–30 years (18.87%). Clinical and radiographic PB was found to be higher in males (37.94 ± 1.28 mm, 38.87 ± 3.11 mm) than females (35.44 ± 1.18 mm, 36.62 ± 2.75 mm). PL demonstrated almost similar clinical values in males (45.25 ± 1.65 mm) and females (45.21 ± 1.51 mm) with no statistical significance. Radiographic PL was significantly higher in males (48.28 ± 1.60 mm) than females (46.41 ± 1.69 mm). Males demonstrated higher PI, clinically and radiographically (83.84 ± 3.82 mm, 80.51 ± 5.32 mm), than females (78.38 ± 4.19 mm, 78.91 ± 5.06 mm). CONCLUSION: Palatal parameters showed significant differences suggesting sexual dimorphism. They serve as important anthropometric, clinical, and radiographic tools useful in the identification of deceased individuals as a part of forensic medicine and odontology.
背景:在体质人类学中,腭部一直是人类骨骼遗骸性别鉴定的一个重要课题。腭指数(PI)是确定身份不明的死者性别的一个重要参数。研究目的:本研究旨在确定和比较临床和放射学上的腭部指数,并评估其在中印度人群性别二形性中的作用。材料与方法:这项研究是在印度一所高级医学院的解剖学和牙科学系对 392 名参与者进行的。使用上颌石膏进行临床测量。放射学方法采用后正位和侧位头影(Ceph)。测量腭长(PL)和腭宽(PB)。PI 的计算公式为 PB/PL × 100。数据采用非配对的学生 t 检验进行分析。结果:受试者的年龄分别为 41-50 岁(31.63%)、51-60 岁(27.04%)和 18-30 岁(18.87%)。临床和放射学检查发现,男性的 PB 值(37.94 ± 1.28 mm,38.87 ± 3.11 mm)高于女性(35.44 ± 1.18 mm,36.62 ± 2.75 mm)。男性(45.25 ± 1.65 毫米)和女性(45.21 ± 1.51 毫米)的 PL 临床值几乎相似,但无统计学意义。男性(48.28 ± 1.60 毫米)的影像学 PL 值明显高于女性(46.41 ± 1.69 毫米)。在临床和影像学上,男性的 PI(83.84 ± 3.82 mm,80.51 ± 5.32 mm)均高于女性(78.38 ± 4.19 mm,78.91 ± 5.06 mm)。结论:腭部参数显示出显著差异,表明存在性别二态性。作为法医学和牙科学的一部分,它们是重要的人体测量、临床和放射学工具,有助于鉴定死者身份。

Foreign body aspiration (FBA) is one of the common causes of significant morbidity and mortality in a toddler child. Airway foreign bodies might be presented as a spectrum, ranging from the acute onset of choking, cyanosis, and respiratory distress to delayed onset of mild respiratory distress, wheezing, persistent cough, and fever. Here, we report a case of peanut aspiration in a toddler child, who was initially being treated as acute bronchial asthma, and the diagnosis was subsequently confirmed on computed tomography (CT) chest as a case of tracheal FBA. A foreign body was successfully retrieved by rigid bronchoscopy under general anesthesia and was a peanut by morphology. The possibility of FBA should be considered in any toddler child, who presents for the first time with acute bronchial asthma-like symptoms; wheezing, coughing, or respiratory distress. In a resource-limited setting, low-dose CT chest can be an early noninvasive diagnostic tool to detect all airway foreign bodies.
异物吸入(FBA)是导致幼儿严重发病和死亡的常见原因之一。气道异物的表现多种多样,从急性发作的窒息、发绀和呼吸困难,到延迟发作的轻度呼吸困难、喘息、持续咳嗽和发热。在此,我们报告了一例幼儿吸入花生的病例,该患儿起初被当作急性支气管哮喘治疗,后经胸部计算机断层扫描(CT)确诊为气管异物吸入症。在全身麻醉的情况下,通过硬质支气管镜成功取出了异物,从形态上看是花生。任何首次出现急性支气管哮喘样症状、喘息、咳嗽或呼吸困难的幼儿都应考虑到气管异物的可能性。在资源有限的情况下,低剂量胸部 CT 可以作为一种早期无创诊断工具来检测所有气道异物。

INTRODUCTION: Cluster of differentiation 44 (CD44), a transmembrane glycoprotein and Matrix metalloproteinase 2 (MMP2), a gelatinase enzyme have been implicated in several malignancies for their role in prognostication and diagnosis. We, therefore, made an effort to use these markers in urothelial malignancies and discuss their importance along with review of the literature. METHODS: A prospective study conducted for 1 year using light microscopy and immunohistochemistry for CD44 and MMP2. RESULTS: CD44 showed concordance with low-grade tumors while MMP 2 was found to show positivity in high-grade tumors. Score 3 in CD44 expression was seen exclusively (100%) in low-grade tumors while similar score of MMP2 expression was seen in 90.9% of high-grade tumors. CONCLUSION: CD44 and MMP2 expression can, therefore, serve as an important tool to predict the clinical behavior and prognosis in patients of urothelial carcinoma of the bladder. The management and survival rate varies according to grade; hence, these markers can be used for prognostication of disease.
引言:分化簇 44(CD44)是一种跨膜糖蛋白,基质金属蛋白酶 2(MMP2)是一种明胶酶,它们在多种恶性肿瘤的预后和诊断中发挥着重要作用。因此,我们尝试在尿路恶性肿瘤中使用这些标记物,并在回顾文献的同时讨论它们的重要性。方法:一项为期一年的前瞻性研究,使用光学显微镜和免疫组化技术检测 CD44 和 MMP2。结果:CD44 显示与低级别肿瘤一致,而 MMP 2 则在高级别肿瘤中显示阳性。在低分级肿瘤中,CD44表达评分为3分者占100%,而在90.9%的高级别肿瘤中,MMP2表达评分与之相似。结论:因此,CD44 和 MMP2 表达可作为预测膀胱尿路上皮癌患者临床表现和预后的重要工具。不同级别肿瘤的治疗和存活率各不相同,因此这些标记物可用于疾病的预后。

Multiple facial bone fractures usually are consequential to severe injuries secondary to motor vehicle calamities. These complex and panfacial fractures are usually associated with multiple systemic injuries that mandate a multidisciplinary approach to their management. It involves rebuilding the facial architecture and restoring the facial buttresses to reinstate the cosmetics and function. The complex nature of treatment makes them challenging for the surgeon and thus requires an organized approach for efficient reduction. Various sequences such as bottom–up, top-to-bottom, and occlusion first have been commonly used. This case series presents two cases of complex facial fractures and two cases of panfacial fractures. In these cases, occlusion was first achieved by maxillomandibular fixation. The mandible was first reduced and fixed, followed by the maxilla.
多发性面部骨折通常是继发于机动车事故的严重损伤的结果。这些复杂的泛面部骨折通常伴有多种系统性损伤,因此需要采用多学科方法进行治疗。这包括重建面部结构和恢复面部支撑,以恢复美观和功能。治疗的复杂性使其对外科医生来说具有挑战性,因此需要一种有组织的方法来有效地缩小骨折。常用的方法有自下而上、自上而下和先咬合等。本病例系列介绍了两例复杂的面部骨折和两例泛面部骨折。在这些病例中,首先通过上颌骨固定实现了咬合。首先对下颌骨进行缩小和固定,然后是上颌骨。

Primary hyperparathyroidism (PHPT) is usually seen in females above the age of 50 years, with a prevalence of 21/1000 whereas the incidence in patients aged 12–28 years is <5%. A solitary adenoma is responsible for 80% of cases of PHPT. PHPT is most commonly asymptomatic. The young age of the patient and her presentation with osteoporosis and bone fractures make this an extremely rare presentation of parathyroid adenoma (PTA). Here, we report a case of PTA in a young female presented with pathological fracture of tibia and humerus. The case was diagnosed as PTA based on clinical symptoms and investigations. Surgical intervention, i.e. parathyroidectomy was performed under GA.
原发性甲状旁腺功能亢进症(PHPT)通常见于50岁以上的女性,发病率为21/1000,而12-28岁患者的发病率则低于5%。80%的高钙血症病例由单发腺瘤引起。PHPT 多无症状。由于患者年龄较小,且伴有骨质疏松症和骨折,因此这是一种极为罕见的甲状旁腺腺瘤(PTA)表现。在此,我们报告了一例年轻女性的PTA病例,她的胫骨和肱骨均出现病理性骨折。根据临床症状和检查结果,该病例被诊断为 PTA。手术治疗,即在全麻下进行甲状旁腺切除术。
