Reconstruction of calvarial bone defects from congenital anomaly or from bone loss due to traumatic or neoplastic processes remains a significant problem in craniofacial surgery and neurosurgery. To facilitate bone regeneration, there have been many trials such as autologous bone graft or allograft, and the addition of demineralized bone matrix and matrix-derived growth factor. Guided bone regeneration is one of the methods to accelerate bone healing for calvarial bone defects especially in children. Pericranium is one of the most usable structure in bone regeneration. It protects the dura and sinus, and provides mechanical connection between bone fragments. It supplies blood to bone cortex and osteoprogenitor cells and enhances bone regeneration. For maximal effect of pericranium in bone regeneration, authors used pericranium as a flap for covering calvarial defects in surgeries of 11 craniosynostosis patients and achieved satisfactory results: The bone regeneration of original cranial defect in one year after operation was 74.6%(+/-8.5%). This pericranial flap would be made more effectively by individual dissection after subgaleal dissection rather than subperiosteal dissection. In this article, we reviewed the role of pericranium and reported its usefulness as a flap in surgery of craniosynostosis to maximize bone regeneration.

The widespread presence of large-scale genomic variations, termed copy number variation (CNVs), has been recently recognized in phenotypically normal individuals. Judging by the growing number of reports on CNVs, it is now evident that these variants contribute significantly to genetic diversity in the human genome. Like single nucleotide polymorphisms (SNPs), CNVs are expected to serve as potential biomarkers for disease susceptibility or drug responses. However, the technical and practical concerns still remain to be tackled. In this review, we examine the current status of CNV DBs and research, including the ongoing efforts of CNV screening in the human genome. We also discuss the characteristics of platforms that are available at the moment and suggest the potential of CNVs in clinical research and application.

BCG (Bacillus Calmette-Guerin), which produces resistance to tuberculosis infection, is a vaccine containing live, attenuated Mycobacterium bovis. It induces specific and nonspecific dermatologic complications. The specific reactions include scrofuloderma-like, lupus vulgaris-like, lichen nitidus-like, lymphadenitis and tuberculid. We report a case of papular tuberculid, which was presented as 3-5mm sized erythematous papules on the extremities and face, and BCGitis had developed around the vaccination site after BCG vaccination. Histopathologic examination of the papule and lymph node showed granuloma, consisting of epithelioid cells and lymphocytes.

Neurofibroma may present as multiple or solitary lesions. Although there is no predilection site of solitary lesion, the occurrence on hands is rare. We herein report a case of solitary neurofibroma in 33-year-old female patient, who presented with a 0.5 x 0.5 cm sized, soft, dome-shaped papule on the left palm with typical histologic findings.

The rapid advances in genetic knowledge and technology raise various, sometimes unprecedented, ethical dilemmas in the scientific community as well as the public realm. To deal with these dilemmas, the international community has prepared and issued ethical standards in various formats. In this review, seven international standards regarding genetics and genomics will be briefly introduced in chronological order. Critical reflections on them will not be provided in this review, and naturally, they have their own problems and shortcomings. However, a common set of the principles expressed in them will be highlighted here, because they are still relevant, and many of them will be more relevant in the future. Some of the interesting contents will be selected and described. After that, the morality of one recent event related to whole-genome sequencing and person-identifiable genetic data will be explored based on those international standards.

Dystrophic calcinosis cutis is diagnosed, when calcium is deposited in the previously damaged tissue by connective tissue disease, panniculitis, pseudoxanthoma elasticum or trauma. We report a case of dystrophic calcinosis cutis arising from the lesion of clear cell syringoma. A 73-year-old woman presented with asymptomatic, multiple, skin-colored to whitish flat papules on the forehead. A punch biopsy specimen revealed amorphous basophilic materials in the upper dermis, as well as a large number of nests of clear cells in the middle dermis.

In November 2013, the US Food and Drug Administration (FDA) sent a warning letter to 23andMe, Inc. and ordered the company to discontinue marketing of the 23andMe Personal Genome Service (PGS) until it receives FDA marketing authorization for the device. The FDA considers the PGS as an unclassified medical device, which requires premarket approval or de novo classification. Opponents of the FDA's action expressed their concerns, saying that the FDA is overcautious and paternalistic, which violates consumers' rights and might stifle the consumer genomics field itself, and insisted that the agency should not restrict direct-to-consumer (DTC) genomic testing without empirical evidence of harm. Proponents support the agency's action as protection of consumers from potentially invalid and almost useless information. This action was also significant, since it reflected the FDA's attitude towards medical application of next-generation sequencing techniques. In this review, we followed up on the FDA-23andMe incident and evaluated the problems and prospects for DTC genetic testing.

Solitary fibrous tumor (SFT) belongs to a group of mesenchymal tumors, first described as a primary spindle cell tumor of the pleura in 1931. Recently, SFT has been reported in various locations with no relation to serosal surface, such as the mediastinum, head and neck, orbit and urogenital system. Histopathologically, the tumors have a disorganized or "patternless" arrangement of spindle cells in a collagenous background and prominent vascular channels of varing size. To date, only 22 cases of SFT arising from the nasal cavity and paranasal sinuses have been reported in the world literature. We report a case of SFT localized in the right nasal cavity with extension to the right ethmoid sinus with a review of literature.
