Misdiagnosed fibrosarcoma of the mandible mimicking temporomandibular disorder: a rare condition.

The jawbones can be sites of various neoplastic conditions. Given the variety of processes affecting this particular anatomical area, formulation of a precise diagnosis can be challenging to clinicians. Limited jaw movement, pain, and facial asymmetry are common signs among patients, especially those with temporomandibular disorder (TMD). This paper reports a case of primary fibrosarcoma affecting the mandible and surrounding structures in a 14-year-old girl presenting signs and symptoms similar to TMD. Her condition was misdiagnosed, and she was treated for TMD over an extended period before the correct diagnosis was made for fibrosarcoma. The patient underwent surgical resection with postsurgical radiotherapy and chemotherapy and now is being followed up. Although malignant lesions are rare in the temporomandibular joint (TMJ) region, dentists are advised to be aware of the condition and to keep in mind that patients who are admitting for TMD can also possibly be affected from neoplasms. Hence, those patients have to be examined meticulously to avoid misdiagnosis and mistreatment.

Increased neopterin level and chitotriosidase activity in pregnant women with threatened preterm labor

Objectives: To determine whether the cellular inflammatory markers of activated macrophages, neopterin (NEO), chitotriosidase activity and the acute-phase inflammatory marker C-reactive protein (CRP) are elevated in pregnancy with threatened preterm labor (TPL).

Methods: Thirty-two pregnant women with TPL and 32 women with uncomplicated pregnancy (UP) were included this study. The primary aim was to compare the NEO, chitotriosidase activity and CRP levels between women with TPL and women with UP.

Results: NEO levels were all significantly elevated in patients with TPL compared to UP (median 25–75%; 9.61 [8.47–12.29] versus 4.46 [3.59–6.92], respectively; p?p?=?0.036). However, CRP levels were not different in women with TPL compared to UP (p?=?0.573). Furthermore, a significant moderate negative correlation was found between delivery week and NEO level (r?=??0.557, p?=?0.001). However, a significant correlation was not seen between delivery week and chitotriosidase activity (r?=??0.042, p?=?0.741).

Conclusions: Inflammatory markers such as NEO and chitotriosidase activity, which are markers of macrophages, are more elevated in pregnant women with TPL than in women with UP. These data suggest that there are striking increases in inflammation and cellular immune activation in TPL.     

Investigation of the choroidal thickness in patients with hypothyroidism

Purpose:

The effect of hypothyroidism on the choroidal thickness (CT) was investigated in patients with subclinical hypothyroidism and overt hypothyroidism, and biochemically and clinically euthyroid patients receiving levothyroxine treatment. The patients were compared with healthy subjects.

Materials and Methods:

One eye of 71 hypothyroid and 22 healthy subjects between 20 and 40 years of age were included in this study. CT measurements were taken at the fovea and at 2 points that were 1500 μm nasal and temporal to the fovea using spectral-domain optical coherence tomography. Independent sample t-test''s and was used for statistical analysis of the data.

Results:

The CT was significantly thicker in hypothyroid patients compared to healthy subjects (P values were 0.013 for subfoveal, 0.015 for temporal and 0.020 for nasal segments). The intraocular pressure (IOP) and body mass index (BMI) were also significantly higher in hypothyroid patients (P values were 0.021 and 0.003, respectively). There was not a statistically significant difference in the BMI and IOP measurements between healthy subjects and euthyroid patients (P > 0.05). However, there was a statistically significant difference in the subfoveal, temporal and nasal CT measurements between healthy subjects and euthyroid patients (P values were 0.006, 0.031 and 0.013, respectively).

Conclusions:

All subgroups of hypothyroid patients had thicker CT compared to healthy subjects. Euthyroid patients receiving levothyroxine treatment had lower IOP, BMI levels, and serum lipid levels than patients with subclinical hypothyroidism and overt hypothyroidism.     

COVID-19 autopsies: conclusions from international studies

The rapid pace at which COVID-19 studies are being published is surpassed only by the spread of the virus and the destruction wreaked by the pandemic globally. Therefore, it is likely that, even in the few months prior to this article reaching print, the COVID-19 literature would have moved on. The authors of this article work at a centre for COVID autopsies in London, and the aim of the article is, using their first-hand experience of COVID-19 autopsies, to distil what in their judgement are the most valid and important findings of internationally published COVID-19 autopsy studies. The intention is to provide an illustrated summary of the pathology of the organ systems most often affected by COVID-19, which will be particularly useful to trainee histopathologists and to busy consultant surgical histopathologists who may not have encountered COVID-19 first hand. For the reader who wishes to probe further the question of pathogenesis, a few pertinent references are provided.     

Clinical trial: transcutaneous interferential electrical stimulation in individuals with irritable bowel syndrome - a prospective double-blind randomized study

Background: The exact etiology of irritable bowel syndrome (IBS) remains unclear. Curative treatment is not available and current treatment modalities are mainly directed against the predominant symptoms. There are a few studies reporting the beneficial effects of transcutaneous electrical stimulation in patients with chronic constipation, gastroparesis, and functional dyspepsia. Aim: To investigate whether transcutaneous electrical stimulation is an effective procedure in IBS patients. Methods: IBS patients were randomly placed in vacuum interferential current (IFC) and placebo groups. Both treatments consisted of 12 sessions administered over 4 weeks. Symptoms due to IBS were documented via questionnaires, including the IBS Global Assessment of Improvement Scale, numeric rating scales, visual analogue scale, and IBS Quality of Life Scale at the beginning of, end of, and 1 month after the treatment. Results: Patients in the therapy (29 cases) and placebo (29 cases) groups were homogeneous with respect to demographic data and gastrointestinal system symptoms. When compared to the beginning scores, severity of abdominal discomfort, bloating, and abdominal distension and rumbling improved significantly in either interference or placebo groups at both the end of treatment and 1 month after treatment. In the IFC group, severity of symptoms continued to decrease significantly at 1 month after treatment when compared to scores at just the end of treatment, whereas in the placebo group severity of these symptoms did not change significantly on numeric severity scales. Also, the visual analogue scale of the first month after treatment continued to decrease significantly when compared to the level at the end of treatment in the IFC group. Total quality score increased significantly in the IFC group. Conclusions: Vacuum IFC therapy can significantly improve symptoms and quality of life in patients with IBS. It may represent a novel treatment modality for drug-refractory IBS patients.     

Asian consensus report on functional dyspepsia

Background and Aim: Environmental factors such as food, lifestyle and prevalence of Helicobacter pylori infection are widely different in Asian countries compared with the West, and physiological functions and genetic factors of Asians may also be different from those of Westerners. Establishing an Asian consensus for functional dyspepsia is crucial in order to attract attention to such data from Asian countries, to articulate the experience and views of Asian experts, and to provide a relevant guide on management of functional dyspepsia for primary care physicians working in Asia. Methods: Consensus team members were selected from Asian experts and consensus development was carried out by using a modified Delphi method. Consensus teams collected published papers on functional dyspepsia especially from Asia and developed candidate consensus statements based on the generated clinical questions. At the first face‐to‐face meeting, each statement was reviewed and e‐mail voting was done twice. At the second face‐to‐face meeting, final voting on each statement was done using a keypad voting system. A grade of evidence and strength of recommendation were applied to each statement according to the method of the GRADE Working Group. Results: Twenty‐nine consensus statements were finalized, including seven for definition and diagnosis, five for epidemiology, nine for pathophysiology, and eight for management. Algorithms for diagnosis and management of functional dyspepsia were added. Conclusions: This consensus developed by Asian experts shows distinctive features of functional dyspepsia in Asia and will provide a guide to the diagnosis and management of functional dyspepsia for Asian primary care physicians.
