  • Dracunculiasis, otherwise known as guinea worm disease (GWD), is caused by infection with the nematode Dracunculus medinensis. This nematode is transmitted to humans exclusively via contaminated drinking water. The transmitting vectors are Cyclops copepods (water fleas), which are tiny free-swimming crustaceans usually found abundantly in freshwater ponds. Humans can acquire GWD by drinking water that contains vectors infected with guinea worm larvae. This disease is prevalent in some of the most deprived areas of the world, and no vaccine or medicine is currently available. International efforts to eradicate dracunculiasis began in the early 1980s. Most dentists and maxillofacial surgeons have neglected this kind of parasite infection. However, when performing charitable work in developing countries near the tropic lines or other regions where GWD is endemic, it is important to consider GWD in cases of swelling or tumors of unknown origin. This paper reviews the pathogenesis, epidemiology, clinical criteria, diagnostic criteria, treatment, and prevention of dracunculiasis. It also summarizes important factors for maxillofacial surgeons to consider.

  • Horizontal root fracture (HRF) is a result of trauma to teeth and periodontium, which implies severe injury to cementum, dentin, and pulp. This is a rare case of HRF in the maxillary lateral incisor of a 62-year-old male who only presented persistent gingival swelling, fistula, and dull pain at first. An apical radiolucency of unknown origin turned out to be a result of hidden HRF at the coronal third level that was later visualized radiographically during endodontic treatment. The tooth was scheduled to be extracted upon the patient's agreement. The purpose of this report is to alert clinicians about the importance of diagnosing HRF through thorough clinical and radiographic examinations. Where there is persistent fistula without proper cause, HRF should be considered as a causative factor, and the diagnosis could be effective with aid of cone beam computed tomography, electronic root apex locator, as well as other clinical signs.

  • Stevens-Johnson 증후군은 피부에 특징적 발진과 수포를 동반하고 두 개 이상의 점막 조직에 병변을 보이는 것을 특징으로 하는 질환으로 감염, 예방 접종, 약물, 전신 질환 및 물리적 자극 등이 원인이 될 수 있다. 이 가운데 Mycoplasma pneumoniae는 소아기의 Stevens-Johnson 증후군의 가장 흔한 원인이다. 최근 Mycoplasma pneumoniae에 의한 피부 병변 없이 심한 점막의 병변만을 보이는 경우가 보고되었다. 이러한 경우를 피부 병변이 없는 Stevens-Johnson 증후군이거나 혹은 다른 개별적 질환으로 보아야 할지에 대해서는 아직 논란이 되고 있다. 병력에서 특이 사항이 없는 발열과 심한 경구 및 입술의 병변과 결막염으로 입원한 6세 남아가 임상 검사에서 Mycoplasma 항체 증가 이외에는 특이 소견을 보이지 않아 저자들은 Mycoplasma에 의한 피부병변 없는 Stevens-Johnson증후군으로 진단하였고 이를 문헌 고찰과 함께 보고하는 바이다.
