The authors presented a case of gastroschisis with a pedunculated gallbladder embedded in hepatic tissue. The patient was born after fullterm gestation. Due to extensive abdominal wall defect, she succumbed 3 days after birth. There was a pedunculated mass measuring 2.5x1.5x1.5 cm between the liver and distended stomach without any attachment to the liver. The pedicle of the mass was connected to the common bile duct. Cut surface revealed that the mass was an accessory hepatic lobe encircling the gallbladder. The histologic feature of both accessory liver and gallbladder was markedly altered probably due to vascular obstruction. We could find only a single similar case in literlature. That case was associated with Beckwith syndrome and ours was associated with large atrial spetal defect, large patent ductus arteriosus, accessory spleen as well as gastroschisis. The common feature of abdominal wall defect might be a predisposing factor.

The digital workflow of optical impressions by the intraoral scanner and CADCAM manufacture of dental prostheses is actively developing. The complex process of traditional impression taking, definite cast fabrication, wax pattern making, and casting has been shortened, and the number of patient’s visits can also be reduced. Advances in intraoral scanner technology have increased the precision and accuracy of optical impression, and its indication is progressively widened toward the long span fixed dental prosthesis. This case report describes the long span implant case, and the operator fully utilized digital workflow such as computer-guided implant surgical template and CAD-CAM produced restoration after the digital impression. The provisional restoration and customized abutments were prepared with the optical impression taken on the same day of implant surgery. Moreover, the final prosthesis was fabricated with the digital scan while utilizing the same customized abutment from the provisional restoration. During the data acquisition step, stl data of customized abutments, previously scanned at the time of provisional restoration delivery, were imported and automatically aligned with digital impression data using an ‘A.I. abutment matching algorithm’ the intraoral scanner software. By using this algorithm, it was possible to obtain the subgingival margin without the gingival retraction or abutment removal. Using the digital intraoral scanner’s advanced functions, the operator could shorten the total treatment time. So that both the patient and the clinician could experience convenient and effective treatment, and it was possible to manufacture a prosthesis with predictability.

Hamartoma of the breast is a rare benign lesion presenting as palpable mass. They are, however, sometimes misdiagnosed by pathologist due to their resemblance to other benign or physiologic conditions of the breast. We report two cases of hamartomas of the breast. The clinical diagnosis was fibroadenoma in both cases. One patient was a 49-year-old woman presented with palpable mass for the duration of 5 months. Mammography showed a well demarcated round mass with homogeneous density which is slightly greater than the surrounding glandular tissue. Grossly it was a 3.5 3.0 2.0 cm sized round firm mass covered by thin fibrous tissue. Microscopically it was a well defined mass composed of variable amount of breast lobules, dilated ducts and adipose tissue surrounded by dense hyalinized connective tissue. The adipose tissue accounted for 30% of the entire lesion. Cellular atypism was not found. The other patient was a 18-year-old woman presented with palpable mass of the duration of 3 years, which was increased in size recently. Mammography demonstratesd a well delimited lobulated mass with lucent halo. Ultrasonography showed a well encapsulated low echoic mass admixed with high echoic areas. Grossly, it was a 4.0 4.0 2.0 cm sized well demarcated oval-shaped firm mass with translucent thin fibrous capsule.. Microscopic findings were similar to the former. The amount of adipose tissue was 20%.

Statements of problem: Zirconia core is used for posterior fixed partial dentures because it's good mechanical properties. Stress is concentrated on connectors in fixed partial dentures, so the proper design of connector areas is needed for adequate mechanical long-term properties of any prosthesis. The area of connector is critical, but tooth size and surrounding soft tissue limit the connector design. PURPOSE: The purpose of this study is to compare fracture strengths between different connector designs of zirconia core for posterior fixed partial dentures manufactured with CAD/CAM system and determining the optimal connector design satisfying strength and hygiene. MATERIAL AND METHOD: The following four groups of 40 posterior fixed partial denture specimens(each group 10) were fabricated as followed; group 1, vertical height of connector is 3mm(control group, all groups have the same condition); group 2, lingual vertical 1mm reinforcement on connector; group 3, lingual vertical 2mm reinforcing on connector and group 4, lingual vertical 3mm reinforcing on connector. Specimens were subjected to compressive loading on the central fossa of pontic by instron. SEM was used to identify the initial crack and characterize the fracture mode. RESULTS: The results were as follows: 1. The mean fracture load of the non-lingual reinforcing group was 1212N and the lingual vertical 1mm reinforcing group was 1510N, the lingual vertical 2mm reinforcing group was 1882N, the lingual vertical 3mm reinforcing group was 1980N. 2. The reinforcing groups were statistically significant compared to non-reinforcing groups(P<0.001). 3. There were 2, 3mm reinforcing groups that were statistically significant compared to 1mm reinforcing groups(P<0.001), and the 3mm reinforcing group was not statistically significant compared to 2mm reinforcing groups(P>0.05) 4. Fractures were initiated in gingival embrasures of connectors and processed to the loading site. CONCLUSION: In this study, lingual reinforcement of connector for improved strength of zirconia based fixed partial denture is nessasary. And long-term study for clinical application is required.

Albinism is an inherited ongenital disarder in which there is sgr neralized decrease or absence of pigrnent in the eyes, skin, and hair. There are two general groups (1) Oculocutneou albinism, (2) Ocular albinism. Skin cancers in albinos are rare in ternperate clirnats and t.hey occur rnostly on sun ex posed areas. We present a case of recurrance of squarnous cell carcinoma ir a Korean albinoid on both sides of the neck and right ear. On liistopathologic examination, we find I or pearls, and irregular mases of epidermal cells that proliferite downward into the devmis. The invaing cell masses are composed of atypical squamous cells.
