Evaluating a single dental anxiety question in Finnish adults

Objective. To evaluate the psychometric properties (criterion validity, construct validity, sensitivity, and specificity) of a single-item question screening for dental anxiety in a Finnish adult population. Material and methods. A total of 823 subjects, ranging in age from 18 to 87 years, answered a questionnaire comprising sections assessing the respondents’ demographic profile and dental attendance patterns. A single dental anxiety question and the Modified Dental Anxiety Scale (MDAS) were included. The final response rate was 85%. Results. Eight percent of the sample was highly dentally anxious using the MDAS cut-off point of 19 or above. Twelve percent of the respondents rated themselves as “very scared” on the single-item question. The percentage agreement between the single-item question and the MDAS was 93; the Kappa coefficient was 0.63. Specificity of the single question was 0.95 while sensitivity was 0.80 using the MDAS dichotomous classification. The single-item question related to age (p<0.001), gender (p<0.001), and dental attendance (p<0.001), as predicted. Conclusions. The single question has good validity, specificity, and sensitivity and may be used with confidence to assess dental fear in such situations as national health surveys or in routine dental practice where a multi-item dental anxiety questionnaire is not feasible.     

Poor responses to tyrosine kinase inhibitors in a child with precursor B‐cell acute lymphoblastic leukemia with SNX2‐ABL1 chimeric transcript

In addition to BCR, various rare fusion partners for the ABL1 gene have been reported in leukemia. We have identified the fusion gene SNX2‐ABL1 in a pediatric case of acute lymphoblastic leukemia (ALL), which has only once previously been reported in an adult patient. Cytogenetic analysis detected this fusion gene arising from a t(5;9)(q22;q34) translocation. ALL cells carrying a SNX2‐ABL1 fusion exhibited a BCR‐ABL1+ ALL‐like gene expression profile. The patient poorly responded to dasatinib but partially responded to imatinib. Treatment using tyrosine kinase inhibitors requires further investigation to optimize the genotype‐based treatment stratification for patients with SNX2‐ABL1 fusion.     

Treatment of facial telangiectasia with a small spot of intense pulsed light: A case series of three patients

Intense pulsed light (IPL) technology has long been used in the treatment of facial telangiectasia. While the large spot size of traditional IPL devices offers rapid coverage, it has limitations in terms of visibility and uniform contact with the skin in contoured areas of the face. The novel IPL used in this study had a small spot size (6.35 mm) and shorter wavelength (500–635 nm), allowing the use of high fluence without burning the normal epidermal tissue surrounding the lesion, thus providing better efficacy. Treatment of facial telangiectasia using small‐spot IPL is effective with a low risk of dermatological damage, and its uses for medical care are expected to diversify.     

Successful application of molecular biological technique for evaluation of changes in periodontopathic bacteria in Japanese children with developmental disabilities

Developments in molecular biological techniques enables rapid and easy identification of periodontopathic bacterial species in clinical specimens. However, there are few reports regarding their application for community dentistry. The aim of this study was to show successful application of a molecular biological technique for evaluation of changes in periodontal bacterial species in children at daycare centers. We studied 187 children who received oral examinations in 2009 and 186 who received examinations in 2010, among whom 102 were examined in both years. Clinical parameters regarding periodontal conditions were evaluated and the distribution of 10 periodontopathic species in dental plaque specimens were determined by polymerase chain reaction. Periodontal pocket depth values in the 2010 group were significantly smaller than those in 2009. When the subjects were divided into those with (positive group) and without (negative group) Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, or Campylobacter rectus in 2009, the positive group had significantly smaller periodontal pocket values than the negative group. In addition, the rate of subjects with P. gingivalis, T. denticola, T. forsythia, or C. rectus in the positive group in 2010 was significantly reduced. Our findings demonstrate that molecular biological methods provide more information as compared to a standard clinical examination when evaluating changes of periodontal conditions in the field of community dentistry.     

Specific IgE for wheat in tear fluid of patients with allergic conjunctivitis

Context: Allergy to hydrolyzed wheat protein in facial soap has become a major social issue in Japan. It has been reported that the most frequent early symptoms of allergy to hydrolyzed wheat protein in soap are allergic conjunctivitis and rhinitis, while wheat-dependent exercise-induced anaphylaxis can be induced by long-term use.

Objective: We evaluated the relation between tear fluid levels of specific IgE for wheat and the features of allergic conjunctivitis.

Methods: A prospective, non-randomized, cross-sectional study was conducted in 103 patients with moderate to severe allergic conjunctivitis (allergic group) and 20 age- and sex-matched healthy control subjects (control group). Specific IgE for wheat was measured in tear fluid with an immunochromatography assay, and a skin prick test (SPT) was also performed. Symptoms (sneezing, rhinorrhea, nasal obstruction, ocular itching, and lacrimation) were assessed in each subject along with the activities of daily living (ADL) score and the total ocular symptom score for allergic conjunctivitis. A severity score (0, 1, 2, or 3) was assigned for various changes of the palpebral and bulbar conjunctiva, as well as for limbal and corneal lesions associated with allergic conjunctivitis.

Results: The IgE positive rate and specific IgE score were both higher in the allergic group than in the control group (71.8% versus 40.0% and 1.9?±?0.7 versus 1.4?±?0.5). A positive SPT for wheat was also more frequent in the allergic group than in the control group (6.8% versus 0.0%). Within the allergic group, patients with a positive SPT had higher specific IgE scores than patients with a negative SPT (3.3?±?0.5 versus 1.8?±?0.6, p?r?=?0.665), tearing (r?=?0.672), and the total ocular symptom score (r?=?0.204). Wheat IgE in tear fluid was also correlated with the severity of rhinitis symptoms, including sneezing (r?=?0.610), nose blowing (r?=?0.640), and nasal obstruction (r?=?0.677). Furthermore, the tear fluid wheat IgE score was correlated with five objective features of allergic conjunctivitis (p?Conclusions: These results suggest that wheat allergy may be involved in the development of allergic conjunctivitis.

Unilateral active adrenal tuberculosis featuring persistent intermittent fever

The adrenal gland is one of the organs which tuberculosis infects. In most clinical settings bilateral adrenal tuberculosis has been clarified after adrenal insufficiency is overt. On the contrary, active adrenal tuberculosis is rarely detected during the survey of infectious disease. A 68-year-old man was admitted because of intermittent fever. The fever had continued for the last 3 months. The intermittent fever was accompanied with leukocytosis and elevation of C-reactive protein. Serum soluble interleukin-2 receptor was 1920 U/ml, and beta2-microglobulin was 4.0 mg/l. Bacterial cultures of blood, sputa, urine, bone marrow and cerebrospinal fluid did not show any particular bacteria. Mycobacterium tuberculosis was negative in culture of sputa, and there was no tuberculin reaction. Plasma ACTH and serum cortisol were 18.5 pmol/l and 527.0 nmol/l, respectively. Abdominal CT scan showed right adrenal mass with a size of 28 x 20 mm, which was low density and had a well-encapsulated homogenous appearance. After the adrenalectomy, histology verified active adrenal tuberculosis. The intermittent fever disappeared, and white blood cells and C-reactive protein normalized. These findings indicate an atypical, rare case of unilateral, active adrenal tuberculosis closely linked to intermittent fever, and without any other organ involvement.
