  • Pseudohypoparathyroidism type Ia (PHP Ia) is a disorder characterized by multiform hormonal resistance including parathyroid hormone (PTH) resistance and Albright hereditary osteodystrophy (AHO). It is caused by heterozygous inactivating mutations within the Gs alpha-encoding GNAS exons. A 9-year-old boy presented with clinical and laboratory abnormalities including hypocalcemia, hyperphosphatemia, PTH resistance, multihormone resistance and AHO (round face, short stature, obesity, brachydactyly and osteoma cutis) which were typical of PHP Ia. He had a history of repeated convulsive episodes that started from the age of 2 months. A cranial computed tomography scan showed bilateral calcifications in the basal ganglia and his intelligence quotient testing indicated mild mental retardation. Family history revealed that the patient's maternal relatives, including his grandmother and 2 of his mother's siblings, had features suggestive of AHO. Sequencing of the GNAS gene of the patient identified a heterozygous nonsense mutation within exon 11 (c.637 C>T). The C>T transversion results in an amino acid substitution from Gln to stop codon at codon 213 ($p.Gln213^*$). To our knowledge, this is a novel mutation in GNAS.

  • 폐동정맥루를 보이는 환자의 40~60%에서 유전성 출혈성모세혈관확장증이 동반되어 나타나고, 유전성 출혈성 모세혈관 확장증 환자의 약 15% 정도에서 폐동정맥루가 관찰되므로 폐동정맥루 환자에서는 가족력에 대한 조사가 필요하다. 국내에서 폐동정맥루에 대한 보고는 상당수 있어 왔으나 가족력의 동반을 보고한 예는 없었다. 저자들은 객혈을 주소로 입원하여 폐동정맥루로 진단받고 wire coil spring을 이용하여 색전술을 시행한 23세 여자 환자 1예와 그 가족력을 소개하여 보고하는 바이다.

  • 상아질 이형성증은 매우 드물게 발생하는 상염색체 우성 유전 질환이다. 발생학적 원인에 대해서는 아직 명확하게 알려지지 않았으며 인구 100,000당 1명의 발병률을 나타낸다. 상아질 이형성증은 두 가지 형으로 분류가 되며, 치근부위 상아질 형성이상을 보이는 치근형의 제 1형과 치관부위 상아질 형성이상을 보이는 치관형인 제 2형으로 나눠진다. 제 1형 상아질 이형성증은 임상적으로 정상적인 치관형태을 보이고 있으나 동요도를 가지며 방사선학적으로 치수강과 치근관의 폐쇄, 짧은 원추형의 치근형태 및 자발적으로 형성된 치근단 병소가 특징적으로 관찰된다. 본 논문은 한 가족 내에서 아버지를 제외한 4명의 가족 구성원들에게 발생한 제 1형 상아질 이형성증을 관찰한 바, 이에 대해 이환된 가족 구성원들의 임상, 방사선학 및 조직병리학적 소견을 보고하고자 한다. 제 1형 상아질 이형성증은 방사선학적 검사를 시행하지 않고서는 임상적으로 인지하기 어려우며 조기 진단을 통해 정기적인 구강 위생 관리 및 예방치료를 시행할 경우 이환된 치아의 조기 탈락을 예방하거나 지연시킬 수 있을 것이다.

  • Charcot-Marie-Tooth (CMT) disease was described by Charcot and Marie in France and, independently, by Tooth in England in 1886. CMT is the most common form of inherited motor and sensory neuropathy, and is a genetically heterogeneous disorder of the peripheral nervous system. Therefore, many genes have been identified as CMT-causative genes. Traditionally, subclassification of CMT have been divided into autosomal dominant inherited demyelinating (CMT1) and axonal (CMT2) neuropathies, X-linked neuropathy (CMTX), and autosomal recessive inherited neuropathy (CMT4). Recently, intermediate type (CMT-Int) with NCVs between CMT1 and CMT2 is considered as a CMT type. There are several related peripheral neuropathies, such as $D{\acute{e}}j{\acute{e}}rine$-Sottas neuropathy (DSN), congenital hypomyelination (CH), hereditary neuropathy with liability to pressure palsies (HNPP) and giant axonal neuropathy (GAN). Great advances have been made in understanding the molecular basis of CMT, and 17 distinct genetic causes of CMT have been identified. The number of newly discovered mutations and identified genetic loci is rapidly increasing, and this expanding list has proved challenging for physicians trying to keep up with the field. Identifying the genetic cause of inherited neuropathies is often important to determine at risk family members as well as diagnose the patient. In addition, the encouraging studies have been published on rational potential therapies for the CMT1A. Now, we develop a model of how the various genes may interact in the pathogenesis of CMT disorder.

  • Glanzmann's thrombasthenia is a Qualitative platelet disorder characterized by a deficiency in the platelet membrane glycoproteins IIb/IIIa. It belongs to a group of hereditary platelet disorders typified by normal platelet numbers and a prolonged bleeding time. The severity of bleeding does not correlate with the severity of the platelet glycoprotein IIb/IIIa a abnormality. The present case report describes the periodontal treatment of a patient with Glanzmann's thrombasthenia. A 30-year-old female with a history of Glanzmann's thrombasthenia was referred for gingival bleeding on tooth brushing and discomforts in #38 area. The periodontal finding revealed a diagnosis of localized slight adult periodontitis. Root planing and extraction of #38 was performed under 12 pack of platelets transfusion and digital compression was done for hemostasis. The gingival bleeding ceased within a day in maxilla and 2 days later in mandible. 42 pack of platelets was administered for 3 days of post-treatment and for iron-deficiency anemia 3 pack of RBCs was transfused 2 days later. 1 week later the inflammation in gingiva disappeared and gingival stippling appeared. The clinical result we got was good and in such a medically compromised patient it is an ability to maintain a proper oral hygiene that is essential both for oral and systemic health.

  • 본인은 본교실에서 치험한 악골내 발생된 각화성 낭종들중 다발성인 경우에 이상의 증례에서 동반된 이상소견을 의도적으로 조사해 봄으로써, 악골계를 담당하는 의사로서 악골내에서 다발성 낭종이 발견될 때 NBCCS을 간과해서는 안됨을 느끼게 된다. 또한 이상의 증례에서는 확연한 가족력을 찾아볼 수는 없었으나 이 증후군 자체가 상염색체 우성유전으로 인자전달이 잘 되는 것이므로 세심한 주의와 계속적인 관찰이 요하리라 생각된다.

  • Dentinogenesis imperfecta is a dominant autosomal hereditary disorder of dentin formation that affects the deciduous and permanent teeth. Its etiology is characterized by inadequate cell differentiation during odontogenesis. The clinical characteristics of dentinogenesis imperfecta are discolored teeth with a translucency that varies from gray to brown or amber. Radiographically, the teeth exhibit pulp obliteration, thin and short roots, bell-shaped crowns, and periapical bone rarefaction. The aim of this report was to present a case of dentinogenesis imperfecta type II that was followed up over a 17-year period. This report also presents scanning electron microscopy images of the enamel and dentin, showing that both were altered in the affected teeth. The disease characteristics and the treatments that were administered are reported in this study to guide dentists with respect to the need for early diagnosis and adequate follow-up to avoid major sequelae.
