Clinical features of atypical odontalgia; three cases and literature reviews.

ABSTRACT: Atypical odontalgia (AO) is a disease characterized by continuous pain affecting the teeth or tooth sockets after extraction in the absence of any identifiable cause on clinical or radiographic examination. Antidepressants, such as amitriptyline, are reported to be effective in the treatment of AO; however, their efficacy varies depending on the case. In this article, we report three types of AO and discuss its heterogeneity and management.In the first case, a 58-year-old woman presented with a heavy, splitting pain in the four maxillary front post-crown teeth, as if they were being pressed from the side. Her symptoms abated with 20 mg of amitriptyline. In the second case, a 39-year-old woman presented with a feeling of heaviness pain on the right side of maxillary and mandibular molar teeth, face, whole palate, and throat. She was unable to function because of her pain. Her symptoms drastically subsided with 3 mg of aripiprazole. In the third case, a 54-year-old woman presented with a tingling sensation on the left mandibular second premolar and first molar, and an uncomfortable feeling on her provisional prosthesis that made it unbearable to keep the caps on. Her symptoms diminished with 2 mg of aripiprazole added to 30 mg of mirtazapine.AO shows various features and responses to drugs. It is considered not only a purely sensory problem, but also a considerably complex psychological problem, such as rumination about the pain. Investigating the difference in pharmacotherapeutic responses might help to advance the treatment of AO.

Project description:Background and objectives:Fibrillary GN has been defined as an immune complex-mediated GN with amyloid-like fibrils larger than amyloid which are IgG positive and Congo red negative. With discovery of DNAJB9 as a highly sensitive and specific marker for fibrillary GN, the specificity of the morphologic criteria for establishing the diagnosis of fibrillary GN has come into question.Design, setting, participants, & measurements:We sought to (1) determine anatomic characteristics that best define fibrillary GN and (2) identify clinical and pathologic features that predict outcomes.Results:We retrospectively reviewed kidney biopsies from patients diagnosed with fibrillary GN or suspected fibrillary GN between 1997 and 2017 (n=266, 65% female, median age 61). Approximately 11% of kidney biopsies had one or more unusual feature including monotypic deposits, Congo red positivity, or unusual fibril diameter. Fibrillary GN as a possible monoclonal gammopathy of renal significance represented <1% of cases. Immunostaining for DNAJB9 confirmed fibrillary GN in 100% of cases diagnosed as fibrillary GN and 79% of atypical cases diagnosed as possible fibrillary GN. At a median time of 24 months (interquartile range, 8-46 months) after biopsy (n=100), 53% of patients reached the combined primary outcome of ESKD or death, 18% had CKD, and 18% had partial remission. On multivariable analysis, male sex (adjusted hazard ratio [aHR], 3.82; 95% confidence interval [95% CI], 1.97 to 7.37) and eGFR were the most significant predictors of primary outcome (aHR of 8.02 if eGFR <30 ml/min per 1.73 m2 [95% CI, 1.85 to 34.75]; aHR of 6.44 if eGFR 30 to <45 ml/min per 1.73 m2 [95% CI, 1.38 to 29.99]). Immunosuppressive therapy with rituximab was significantly associated with stabilization of disease progression.Conclusions:Detection of DNAJB9 is a useful diagnostic tool for diagnosing atypical forms of fibrillary GN. The outcomes for fibrillary GN are poor and progression to ESKD is influenced predominantly by the degree of kidney insufficiency at the time of diagnosis and male sex. Rituximab may help preserve kidney function for select patients with fibrillary GN.Podcast:This article contains a podcast at https://www.asn-online.org/media/podcast/CJASN/2019_11_04_CJN03870319.mp3.
