ABSTRACT

IgG4-related disease is a novel clinical entity which can affect single or multiple organs. IgG4-related sialadenitis is referred to the salivary gland involvement of IgG4-related disease, with or without other organ involvement. IgG4-related sialadenitis is characterized by painless swelling or enlargement of salivary glands, high serum IgG4 level, abundant IgG4+ plasma cells infiltration with fibrosis histologically, and good response to glucocorticoids. With review of related articles, highlight and provide an overview of the most recent and focused findings and concepts of this disease, including the most significant pathogenic process based on kinds of immunocytes, cytokines, as well as participation of epithelial-mesenchymal transition, the clinical value of elevated serum IgG4 concentration and pathological role of infiltrated IgG4+ plasma cells, the potential relationship with salivary gland malignant tumor, the applying and usefulness of positron emission tomography-CT, the diagnostic utility of lip biopsy, treatment, prognosis, and also future perspectives.

ABSTRACT

One-step transport disc distraction osteogenesis (TDDO) is an effective method for the restoration of mandibular defects. This study aimed to investigate the feasibility of double-step TDDO in the reconstruction of unilateral mandibular segmental defects after tumour resection using internal distraction devices. Six patients with unilateral mandibular segmental defects were reconstructed successfully with this technique. In the double-step TDDO procedure, the mandibular body was lengthened first and then the mandibular ramus was restored. The distraction movement was set at a rate of 0.4mm twice per day. Dental rehabilitation followed distractor removal. The maximal amount of lengthening was 55 mm in the mandibular body and 42 mm in the mandibular ramus. The average amount of lengthening was 52 mm in the mandibular body and 34 mm in the mandibular ramus. The aesthetic and functional results were excellent in all patients. The implants were integrated successfully and dental restoration was satisfactory. In this study, double-step TDDO is a reliable method for reconstruction of mandibular defects after tumour resection, especially for large mandibular defects. This technique is an ideal method for dental rehabilitation, despite the long overall treatment time.

ABSTRACT

Tumor markers have been detected in saliva from patients with oral cancers. In order to investigate the expression of telomerase in saliva and its clinical significance. Sixty-two saliva specimens were collected from 32 patients with oral squamous cell carcinoma and 30 normal persons, the telomerase activity was assayed by telomerase PCR-ELISA method. It was detected positively in 75.0% (24/32) of patients with oral squamous cell carcinoma, while it was positive in 6.67% (2/30) of normal persons, the statistical difference was significant with P < 0.001. But the difference of expression of telomerase activity between the patients in clinical early and late stage was not significant with P > 0.05, the same to that between the patients with and without lymph nodes metastasis with P > 0.05. The results suggest that the telomerase in saliva could be used as an assistant marker for oral squamous cell carcinoma, however, a larger study is encouraged to confirm the value of judgement on clinical stage and lymph nodes metastasis.
