Desmoplastic variant of ameloblastoma is a new and unusual variant of ameloblastoma with extensive stromal desmoplastic proliferation. The authors experienced a case of desmoplastic variant of ameloblastoma with moderate-defined radiolucency on the right maxillary anterior area in 62-year-old female. As a result of careful analysis of clinical, radiological, histopathological examinations, we diagnosed it as desmoplastic variant of ameloblastoma, and the following results were obtained : 1. Main clinical symptoms were nontender bony swelling with normal intact overlying mucosa on the right maxillary anterior area. 2. Radiographically, moderate-defined, multilocular radiolucency on the right maxillary anterior area were shown, and severe cortical bony thinning and expansion to labial and palatal sides were also observed. And this lesion was shown to be extended to the right nasal cavity. 3. Histopathologically, follicle-like epithelial islands with densely abundant collagenous stroma were morphologically compressed.

Objectives : We report an unusual case of a 57-year old woman with spasticity following fever of unknown origin (the origin of her fever was not certain by western medical diagnosis). Malignant hyperthemia with spasticity couldn't be cured by general western medical therapy, and furthermore the function of liver and renal system was worsened as a consequence of drugs. Methods : We diagnosed the watery state of the patient as seupon (습온) with gyeonggwol (경궐) through pattern identification (변증) of symptoms and signs. Results : This patient who had spasticity with malignant hyperthermia was treated by optical management of herb medicine and acupuncture, and should need long-term observation. Conclusions : We want to show that trial by febrile diseases can solve fever and spasticity.

We report the case of a 69-year-old woman who was diagnosed with intracardiac schwannoma without symptoms. Preoperative echocardiography and cardiac magnetic resonance imaging showed a mass attached to the interatrial septum. The initial diagnosis was a myxoma or a bronchogenic cyst. The tumor was successfully excised under cardiopulmonary bypass. However, the pathology of the excised tumor was consistent with schwannoma. We suggest that cardiovascular surgeons consider schwannoma to be a possible differential diagnosis for a mass close to the interatrial septum.

Orbital floor blowout fractures can result in a variety of signs and symptoms depending on the severity of the bone defect. Large defects often result in enophthalmos and restriction of ocular movement; yet the timing of surgery can be delayed up to two weeks with good functional outcomes. In contrast, an orbital trapdoor defect with entrapment of the inferior rectus muscle usually elicits pain with marked restriction of the upward gaze and activation of the oculocardiac reflex without significant dystopia or enophthalmos. When autonomic cardiac derangement is diagnosed along with an orbital floor fracture, it has been suggested that the fracture should be treated immediately. Otherwise, it will result in continued hemodynamic instability and muscular injury and may require a second surgery. This article reports the management of an unusual presentation of a trapdoor blowout orbital floor fracture surgery with oculocardiac response in an adult, with emphasis on its pathophysiology, management, and differential diagnosis.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma. Although progressive lymphadenopathy is a typical feature, extranodal involvement may also occur, including the gastrointestinal tract, skin, bone, thyroid, and testes. Central nervous system invasion is rare, so differentiating it from diseases such as inflammatory demyelinating disorder or infection is essential. DLBCL is therefore a challenge to diagnose, especially when the first findings are neurological symptoms. We report an unusual case of DLBCL that presented as transverse myelitis.

Fenestrated medial patellar plicae are unusual. These fenestrated medial plica may vary in size and shape from being small circular and 5mm in diameter to being large opening 3-4cm long. Arthroscopic resection of the painful medial plica can provide lasting and satisfactory relief of symptoms. There is high percentage of associated medial knee symptoms that are relieved by complete resection. We had performed arthroscopic excision of the symptomatic fenestrated medial plicae present in both knees. The symptoms were dramatically relieved after arthroscopic surgery.

Septic arthritis of the manubriosternal joint is a rare condition, especially in adolescents, who often present with nonspecific symptoms that can mimic more common conditions such as musculoskeletal chest pain, costochondritis. Here, we report a case of septic arthritis in a 17-year-old girl and highlight the challenges in diagnosing and managing this condition in adolescents. Initially presenting with acute chest pain diagnosed as transient nonspecific chest pain, the patient's subsequent visits to the emergency department unveiled escalating symptoms, including high fever, prompting advanced imaging. Ultimately, the diagnosis of septic arthritis of the manubriosternal joint was confirmed, with blood culture growth revealing Methicillin-sensitive Staphylococcus aureus. Diagnostic delays have been attributed to the absence of typical symptoms and patient reluctance to be hospitalized. Our case emphasizes the importance of considering rare infectious etiologies in adolescents with chest pain and emphasizes the need for heightened suspicion in unusual anatomical sites. Further research is required to elucidate the pathogenesis and risk factors associated with this condition to aid in prompt diagnosis and treatment.

Large-scale collapse happened under excavation construction in the past. But, recently the trend that it is completed safely to minimize damages is growing because of increasing levels of design review and detecting signs of problems before the outbreak of large-scale collapse with proactive planning of measurement. In this paper, through studying case collapses over the past, it put the cause of the collapse in order. And then, after reviewing general information on management and utilization of measurement methods which importantly emerging recently, the type and cause of the problem during the excavation was reviewed. And the causes of problem were analyzed by targeting the site which unusual symptoms happened on measuring results under construction. In this study, the awareness that measurement management and subsurface investigation is highly important will increase for preventing large-scale collapse in advance.

Menkes disease is an X-linked recessive copper transport disorder characterized by neurological deterioration, connective-tissue damage, and abnormal hair growth. It is caused by the mutation of the ATP7A gene. This report describes a four-month-old boy with neurological symptoms typical of Menkes disease plus unusual liver involvement. He developed seizures at three months of age and exhibited hypotonia, cephalhematoma, a sagging face, redundant and hypopigmented skin, and abnormal hair growth. In addition, he had unexplained hepatomegaly and high hepatic transaminase. We confirmed the diagnosis of Menkes disease by mutation analysis of the ATP7A gene. To exclude other possible causes for the hepatic abnormalities, a liver biopsy was performed, revealing intracytoplasmic cholestasis, focal spotty necrosis, and minimal lobular activity. The patient's liver involvement may be an underestimated complication of Menkes disease.

Objective: Bidi is an inexpensive, low-processed, hand-rolled tobacco product. In Bangladesh, especially in Rangpur, tobacco farming and bidi processing are common. In this study, we aimed to evaluate the impact of bidi making on children working in bidi factories. Methods: This qualitative(walk-through survey) and quantitative(questionnaire-based survey and a urine cotinine level quantitation) study was conducted in Rangpur, Bangladesh in 2017. Study population included child-workers aged ≤14 years who were regularly employed as bidi makers. Findings: The results of the walk-through survey revealed hazardous working environments at bidi factories. For the quantitative survey, 171 child-workers were categorized into "less-working"(<5 hours/day) and "more-working"(≥5 hours/day) groups; additionally, "forced-working"(forced into work by parents) and "voluntary-working"(working voluntarily) groups were delineated within the same population. In the logistic regression analysis, odds ratios(ORs) of respiratory symptoms and unusual absence(absent ≥5 days/month) were higher in the "more-working" group than in the "less-working" group(unusual absence: OR, 2.91; 95% confidence interval[CI], 1.43-5.94), and this association became higher in the "forced-working" group with longer working hours(OR, 5.68, 95%CI 2.30-14.00). Conclusions: Cheap, hand-rolled tobacco(bidi) is harmful to the health of bidi-making child-workers. Children in poverty bow to the demands of cheap labor and poverty and jeopardize their health and future prospects by working in bidi factories. Tobacco control policies should consider the social effects of tobacco beyond its biological effects.
