Cornelia de Lange Syndrome Accompanied by Cholelithiasis and Nephrolithiasis: A Case Report

Cornelia de Lange syndrome (CdLS) is a rare genetic disorder characterized by a distinctive facial appearance, growth/cognitive retardation, developmental delay, skeletal malformation, hypertrichosis, and other abnormalities. Patients with mild CdLS have less severe phenotypes, while retaining representative facial features. Mutations in the genes NIPBL, SMC1A, SMC3, HDAC8, and RAD21 have been associated with CdLS, with mutations in NIPBL accounting for approximately 60% of cases. Herein, we present a case of CdLS accompanied by cholelithiasis and nephrolithiasis. A 9-year-old Korean boy presented with vomiting and abdominal pain. Abdominal ultrasonography revealed several gallstones and renal stones. Extracorporeal shock wave lithotripsy failed; therefore, cholecystectomy and nephrolithotomy were performed. Postoperative stone composition analysis revealed calcium oxalate as the primary component. CdLS was suspected based on the characteristic appearance and physical examination, with genetic testing confirming an NIPBL gene mutation. Simultaneous CdLS, cholelithiasis, and nephrolithiasis requires careful management and treatment tailored to each patient’s specific needs and challenges.

“Mad Hot” Multiculturalismo: Identidad cultural dominicana a través de la música y la danza

In 1994, a ballroom dance program for 5th graders was implemented in New York public schools. By 2005, more than 6,000 kids from 60 schools in Manhattan, Queens, and Brooklyn were required to take this 10-week course. The very same year, Marilyn Agrelo directed the documentary Mad Hot Ballroom Dance (2005). The documentary tells the story of the preparation, instruction, and rehearsal of various school teams for the Colors of the Rainbows final competition. New York is one of the most multicultural states in the United States with the student population coming from different countries and backgrounds. There are Dominicans, Cubans, Puerto Ricans, European Americans, African Americans, and Asian Americans. Through the music used in this Public-School program (merengue, tango, rumba, and swing), students find an outlet for their feelings and a way to “construct their subjectivities”, as Charles Keil would suggest. It is through dance that, a public school becomes a space of alterity or paratopia; a Korean boy dances a tango with a Dominican girl, whereas a Jewish-American boy dances a merengue with an African-American girl. In this essay, I will argue, among other things, that the ballroom dance program teaches students from different races, religions, and cultural backgrounds not only how to dance but also how to mingle and interact, thus reinforcing the possibility of greater multicultural integration.

C3 glomerulonephritis with genetically confirmed C3 deficiency in a pediatric patient: a case report

Complement component 3 glomerulonephritis (C3GN) is a rare kidney disease characterized by complement dysregulation that results in prominent complement component 3 (C3) deposition in the kidneys. The clinical course of C3GN varies from mild hematuria to progressive chronic kidney disease. In most patients, C3GN is driven by acquired factors, namely, autoantibodies that target C3 or C5 convertases. Genetic variations in complement-related genes are less frequent. We report the case of a 9-yearold Korean boy who presented with microscopic hematuria and a persistently low C3 level and had biopsy findings of C3GN, with the presence of a C3 gene mutation: a frameshift mutation associated with C3 deficiency. However, the patient did not exhibit any other symptoms of complement deficiency. Direct DNA sequencing of his family members revealed the same genetic mutation in his father and older brother. This case report is significant because there are very few such reports worldwide concerning gene mutations related to C3 deficiency to be discovered in patients with C3GN. Explaining C3GN pathogenesis is challenging; therefore, additional research is required in the future.

K-Pop Fandom and Beauty Trends: Investigating the Engagement of Young Urban Indian Women with BTS

The Korean wave (Hallyu) has emerged as a global phenomenon spreading to many countries including India since the nineties. In the initial phase, Korean dramas attracted international attention, after which Korean pop music took the world by storm. With the rising popularity of K-pop in India (Jiju, 2023), it is essential to understand the influence it carries on Indian fans. This paper delves into understanding how K-Pop has influenced ideas about beauty among young adults in Vadodara, a cosmopolitan town located in the western Indian state of Gujarat. Three focus group discussions were carried out with fifteen youngsters who identified as K-pop fans, particularly of BTS (Bangtan Boys), a South Korean boy band formed in 2013. The research design adopted for this study was qualitative and exploratory. Theoretical underpinnings informed by The Social Construction of Reality (Berger & Luckman,1966) and The Juggernaut of Modernity (Giddens, 1990) were used to examine the influence of K-Pop consumption on ideas about beauty in the context of fandom culture. The findings reveal no significant influence on beauty-related values and ideals. However, K-pop does have a positive bearing on other aspects of the lives of its fans such as challenging stereotypes, promoting self-love, addressing social problems, and positive impact on individual personality. In addition, a shift in fashion ideals is observed indicating a growing trend of Korean-inspired fashion trends.

Perilaku informasi penggemar grup k-pop NCT Dream di media sosial Twitter

Introduction. This paper investigate information behavior of NCT Dream fans (The South Korean Boy Band) on Twitter. Previously, from research perspectives, fan behavior and their information behavior studies have not been discussed deeply. Fans have unique ways to use information by collaboratively creating, organizing, disseminating, and sharing information. Research Methods. The paper used a virtual ethnographic research method with a qualitative approach. Observations were conducted to explore the exchange of information and interaction between fans with text, images, video and audio among fellow fans. Data was collected by observations, researchers played a role as participants. Data Analysis. The paper followed the three stages of coding: open coding, axial coding, selective coding. Results and Discussion. Fans are able to create their own information, which later it is considered as community knowledge, although the source of information is not official. The fans demonstrate collaborative, creative, sharing, and performative activities that engage further with information. Conclusion. Fan information behavior involves information creation, information organization, information production, and production. Information behavior of fans on Twitter is informal, diverse, and evolving from the model of fan information behavior offered by Price. Furthermore, because fan behavior has shifted to textual productivity, this information behavior model is very helpful in identifying fans on social media. However, crowdfunding appear as one additional behavior inPrice's information behavior model.

Syndromic craniosynostosis caused by a novel missense variant in MAP4K4: Expanding the genotype-phenotype relationship in RASopathies.

RASopathies represent a distinct class of neurodevelopmental syndromes caused by germline variants in the Ras/MAPK pathways. Recently, a novel disease-gene association was implicated in MAPK kinase kinase kinase 4 (MAP4K4), which regulates the upstream signals of the MAPK pathways. However, to our knowledge, only two studies have reported the genotype-phenotype relationships in the MAP4K4-related disorder. This study reports on a Korean boy harboring a novel de novo missense variant in MAP4K4 (NM_001242559:c.569G>T, p.Gly190Val), revealed by trio exome sequencing, and located in the hotspot of the protein kinase domain. The patient exhibited various clinical features, including craniofacial dysmorphism, language delay, congenital heart defects, genitourinary anomalies, and sagittal craniosynostosis. Our study expands the phenotypic association of the MAP4K4-related disorder to include syndromic craniosynostosis, thereby providing further insights into the role of the RAS/MAPK pathways in the development of premature fusion of calvarial sutures.

Review of Symbolic Interactionism Theory an Adolescent Self-Actualization through Korean Popular Culture

Korean Popular or often abbreviated as K-Pop, the fever is not only felt only in Indonesia, but has gone global. The craze for K-Pop music and Korean drama movies is an inseparable part of Korean fever in various countries. Korean popular culture fever also affects fashion in Indonesia, this can be seen from young people in Indonesia who often imitate Korean fashion. The desire of young people to follow this style of Korean popular culture fashion gives rise to an achievement of their self-actualization. Many teenagers imitate the Korean style, ranging from hairstyles, clothing models, accessories, to lifestyle and how to interact with peers. This is because they really like Korean popular culture such as Korean movies, Korean boy bands, to top Korean stars. One of the reasons is the beauty of the style or style of the film players and boy bands, the beauty of the appearance and physique of the stars, and the dramatic and unique storyline of Korean films. The theory of symbolic interactionism has three concepts, namely mind, self, and society, where these three concepts are strongly influenced by the interpretation of others who make contact or interact with us. The emergence of popular Korean culture is used as a symbol of interaction followed by young Jakartans. The clothes we wear, the way we walk and talk, the work we do, are perceived by others as symbols we build to tell others about who we really are. Who we are is called self-concept (Jones, 2001:145). The concept of interactionism is a guideline to analyze the self-actualization of Jakarta's youth. They fulfill their self-actualization needs, that is, fulfill their desire to be what they want to be.

Novel pathogenic PDX1 gene variant in a Korean family with maturity-onset diabetes of the young.

The diagnosis of maturity-onset diabetes of the young (MODY), a monogenic form of diabetes mellitus caused by a mutation in a single gene, is often uncertain until genetic testing is performed. We report a 13-yr-old Korean boy who was initially diagnosed with type 2 diabetes (T2DM). MODY was suspected because of his nonobese body habitus and family history of multiple affected members. Targeted panel sequencing of all MODY-related genes was performed using the NextSeq 550Dx platform (Illumina). Sanger sequencing was performed using blood samples from the parents, siblings, and other relatives. A frameshift variant in the 3' region of the last exon of PDX1 was detected in the patient and his family members with diabetes. PP1_Moderate criterion was applied and this variant was confirmed to be the genetic cause of diabetes in the family and classified as likely pathogenic. The study highlights the importance of genetic testing for nonobese, early-onset diabetic patients with multiple affected family members. Increased awareness and aggressive genetic testing for MODY are needed.

Intratympanic membrane cholesteatoma after traumatic tympanic membrane perforation: a case report

BackgroundIntratympanic membrane cholesteatoma presents as an asymptomatic, white, round mass on the tympanic membrane, and is usually detected incidentally in children.Case presentationA 12-year-old Korean boy visited our otorhinolaryngology clinic for a whitish mass on the right tympanic membrane. He had a history of traumatic tympanic membrane perforation in the right ear that had occurred 1 year prior, which had healed well with a paper patch placement. The mass was completely removed under local anesthesia during surgery with a microscope. The mass was on the outer epithelial layer of the right tympanic membrane and did not invade the middle fibrous and inner mucosal layers. Cholesteatoma was diagnosed on the basis of histopathology.ConclusionIntratympanic membrane cholesteatoma may not induce symptoms or invade the middle ear because it can grow outwards into the external auditory canal. However, intratympanic membrane cholesteatoma can grow over time, and then after growth, it can compress the tympanic membrane and advance into the middle ear, which can cause symptoms such as hearing loss. Intratympanic membrane cholesteatoma in children should be carefully evaluated and followed, and surgical removal should be considered, even for asymptomatic cases, to minimize potential damage and hearing loss.
