  • Lateral facial cleft is a rare congenital craniofacial anomaly. Their incidence is about 1 in 60,000 births and early treatment with closure in layers is important. Surgical treatment must reconstruct an anatomic and functional situation which give a good esthetic result. This study reports two cases of male at 31 months and 9 months suffered from esthetic problems due to lateral displacement of the oral commisure on the right side. Surgical treatment; the mucosa is closed in with a Z-plasty to avoid intraoral band contracture, the orbicularis oris muscle is closed after interfiber reorientation, and the skin is closed with multiple Z-plasty. So we report two cases of unilateral lateral facial cleft and review of etiopathogenesis in children with lateral facial cleft.

  • Cervical cancer is a leading cause of morbidity and mortality in women worldwide. Although the human papillomavirus (HPV) is considered the major causative agent of cervical cancer, yet the viral infection alone is not sufficient for cancer progression. The etiopathogenesis of cervical cancer is indeed complex; a precise understanding of the complex cellular/molecular mechanisms underlying the initiation, progression and/or prevention of the uterine cervix is therefore essential. Autophagy is emerging as an important biological mechanism in targeting human cancers, including cervical cancer. Furthermore, autophagy, a process of cytoplasm and cellular organelle degradation in lysosomes, has been implicated in homeostasis. Autophagic flux may vary depending on the cell/tissue type, thereby altering cell fate under stress conditions leading to cell survival and/or cell death. Autophagy may in turn govern tumor metastasis and subsequent carcinogenesis. Inflammation is a known hallmark of cancer. Vascular insufficiency in tumors, including cervical tissue, leads to depletion of glucose and/or oxygen perturbing the osmotic mileu causing extracellular acidosis in the tumor microenvironment that may eventually result in autophagy. Thus, targeted manipulation of complex autophagic signaling may prove to be an innovative strategy in identification of clinically relevant biomarkers in cervical cancer in the near future.

  • 십이장에 있는 Brunner씨 선의 양성증식성 병변은 상당히 희유한 변화이다. 지금까지 영문으로 보고된 증례는 대체로 120예를 넘지 않는다. 1835년 Cruveilhier에 의해 처음 증례가 보고되었는 바 대부분의 증례는 양성종양 또는 양성증식성병변으로 나타나나 이 때까지 2예의 악성종양도 보고 되었다. 방사선진단법의 개선과 fibropic endoscopy의 이용으로 십이장의 종양성 병변의 조기진단과 치료에 많은 진전을 보았으며, 따라서 저자는 비교적 희유한 십이장에 생긴 Brunner씨 선에서 발생한 양성종양을 경험하였기에 이 때까지 보고된 문헌을 고찰하고 그 원인, 임상상적 소견, 진단 및 치료에 대한 경험예를 보고하는 바이다. 환자는 51세된 남자로서, 1983년 12월 9일 상북부 동통과 4 주간의 설사를 주소로 하여 본 병원 내과에 입원하여 1984년 l월 23일 ERCP에 의해 십이장에 polyp가 있는 것을 확인하고 외과에서 적출하여 명리조직학적으로 Brunner씨 선에서 발생한 양성선종으로 진단하였다. 본 환자는 그 후 경과가 양호하여 수술후 1년 반까지 아무런 증상 없이 잘 지내고 있음이 확인되었다.

  • Purpose: To demonstrate arthroscopically the presence of bilateral shoulder "mirror lesions" due to overhead work. Materials and Methods: A cross-sectional study was performed in a historical cohort of 10 male tire plant workers who underwent MRI studies of both shoulders. Bilateral intraarticular shoulder pathology was diagnosed by magnetic resonance imaging and confirmed by arthroscopy. "Mirror lesions" were defined as similar pathology between an individual patient's two shoulders. Results: We report on ten patients who had bilateral "mirror lesions." The most common mirror lesions were tears of the rotator cuff. Most patients (7 of 10) had more than one mirror lesion in their shoulders. There were two bilateral full thickness tears involving the supraspinatus and infraspinatus, four bilateral partial thickness supraspinatus tears, six bilateral partial or upper corner lesion complete subscapularis tears, and one bilateral complete supraspinatus tear. Conclusion: Occupational overhead work with simultaneous use of both arms is associated with bilateral shoulder lesions verified by arthroscopy. By demonstrating the work-related bilateral shoulder involvement, this study suggests an etiopathogenesis for these lesions and provides rational for developing worksite prevention strategies.

  • The etiopathogenesis of burning mouth syndrome (BMS) seems to be complex and many patients probably involves interactions among local, systemic, and/or psychological factors in the pathophysiologic mechanism. Although there are controversies over whether the psychological factor is a cause or a result of BMS, several studies have supported strong relationships between psychological factors and chronic pain. It has been suggested that somatic complaints from unfavorable life experiences may influence both individual personality and mood changes; however, initiation of BMS symptoms is not necessarily correlated with stressful life events despite their elevated psychological stress. If the psychological distress is not a causal factor of BMS, it seems that BMS patients may be particularly vulnerable to psychological problems, primarily depression, anxiety, and hostility due to the characteristic entities of BMS such as chronic persistent pain itself. It seems likely that both physiological and psychological factors play a role in causing, perpetuating and/or exacerbating BMS; therefore, both two components of the patient's symptoms must be addressed. The acceptance of psychological factors by the patient is often an important element of BMS, management. The evaluation of psychological and emotional status of BMS patient enables clinicians to recognize prolonged negative and subclinical factors which can complicate the management of pain or indirectly perpetuate other physical factors. This evaluation improves the doctor-patient relationships, motivation, and compliance through a correct understanding of the clinical problem. Appropriate emotional and psychological evaluation may be required prior to developing a treatment plan in order to gain the successful treatment outcome.

  • Individuals with human immunodeficiency virus (HIV) infection present with unique intraoral manifestations of various neoplasms. Intraoral HIV-associated Burkitt's lymphoma is a rare presentation, especially in patients of Indian origin and may present as an initial sign of HIV. The objective of this paper is to report a rare case of Burkitt's lymphoma in an HIV-positive Indian patient along with a special emphasis on differential diagnosis. A 30-year-old Indian female presented with a solitary, well-defined, exophytic mass extending anteroposteriorly and buccolingually from the 35th to 38th regions with no evidence of intraosseous extension. An incisional biopsy was performed, and histopathology showed sheets of neoplastic lymphoid cells with numerous tingible body macrophages with clear cytoplasm, presenting a starry sky appearance, suggesting a diagnosis of BL. The tumor cells were positive for CD10, CD20, c-myc, and Epstein-Barr virus, with a nearly 100% Ki-67 proliferative index. The patient tested positive for HIV. This report indicates the importance of immunohistochemical analysis to differentiate Burkitt's lymphoma from other similar lesions like diffuse large B-cell lymphoma. Thorough knowledge of the clinical presentation, etiopathogenesis, histopathology, and immunoprofile of intraoral HIV-associated Burkitt's lymphoma is essential among clinicians and pathologists.

  • Ulcerative colitis (UC) is one of inflammatory bowel diseases (IBD) with unknown etiopathogenesis. This case report details remission of UC induced by Korean herbal medicine treatment. A 31-year-old male patient diagnosed as UC after a series of examinations including endoscopy and fecal calprotectin (FC) test. He had severe bloody diarrhea over 10-20 times a day despite taking 5-aminosalicylic acid and steroid. He was given individualized Korean herbal medicine Dowha-tang according to pattern identification. After taking Dowha-tang for 7 months, clinical remission was achieved. The symptoms disappeared and FC level went down to normal level. No adverse events were reported. This case report shows that Korean herbal medicine treatment may have the potential for clinical remission of UC. Further investigation is warranted.

  • The sacroiliac joints connect the base of the sacrum to the ilium. When inflamed, they are suspected to cause low back pain. Inflammation of the sacroiliac joints is called sacroiliitis. The severity of the pain varies and depends on the degree of inflammation. Sacroiliitis is a hallmark of seronegative spondyloarthropathies. The presence or absence of chronic sacroiliitis is an important clue in the diagnosis of low back pain. This article aims to provide a concise overview of the anatomy, physiology, and molecular biology of sacroiliitis to aid clinicians in the assessment and management of sacroiliitis. For this narrative review, we evaluated articles in English published before August 2019 in PubMed. Then, we selected articles related to the painful manifestations of the sacroiliac joint. From the retrieved articles, we found that chronic sacroiliitis may be caused by various forms of spondyloarthritis, such as ankylosing spondyloarthritis. Sacroiliitis can also be associated with inflammatory bowel disease, Crohn's disease, gout, tuberculosis, brucellosis, and osteoarthritis, indicating common underlying etiological factors. The pathophysiology of sacroiliitis is complex and may involve internal, environmental, immunological, and genetic factors. Finally, genetic factors may also play a central role in progression of the disease. Knowing the genetic pre-disposition for sacroiliitis can be useful for diagnosis and for formulating treatment regimens, and may lead to a substantial reduction in disease severity and duration and to improved patient performance.

  • Oral verruciform xanthoma (OVX) is an uncommon lesion that appears on the oral mucosa. The aim of this paper was to discuss the probable etiopathogenesis of OVX in the hard palate, reinforcing the importance of including this lesion in the differential diagnosis of verrucous lesions. A 43-year-old male smoker presented with a painless lesion with a verrucous surface and erythematous spots on the hard palate. Excisional biopsy revealed oral mucosa consisting of hyperkeratosis, acanthosis, and elongated rete pegs. Subjacent connective tissue showed numerous foam cells with clear cytoplasm and pyknotic nucleus, negative on periodic acid-Schiff staining. Immunohistochemical analysis revealed foam cells positive for anti-CD68 antibody, while anti-KI-67 antibody was restricted to the basal layer of the oral epithelium. A final diagnosis of OVX was established. The patient showed no signs of recurrence after seven months of follow-up. Physical trauma and smoking habits can be directly related to the etiology of verruciform xanthoma because the lesion is chronic and inflammatory with slow growth, and sites if high trauma are more often affected by such a lesion. The hard palate is the second most commonly affected site, and local trauma caused by smoking can be a cause of this type of lesion.

  • Behcet's disease is a chronic, multisystemic disorder which is more frequently seen in the Mediterranean basin, Middle East, and Far East. The mean age at the first onset is third decades. In large series of patients, men predominate over women. Infectious agents, immune mechanisms, and genetic factors are implicated in the etiopathogenesis of the disease. Eyes, skin, joints, the oral cavity, blood vessels, and central nervous system are usually involved, although less frequently the heart, lung, kidney may be affected. The prognosis of the disease has been improved because of early diagnosis and suitable treatment. Local remedies and systemic administration of colchicine, corticosteoids, immunosuppressives, and other agents have been applied. Pathergy, or skin hypersensitivity to needle puncture has been reported as a diagnostic test for Behcet's disease. We have managed a Behcet's disease patient with pathergy test & corticosteroids therapy. We have obtained good result and report this case with review of literatures.
