Thrombotic Thrombocytopenic Purpura Without Schistocytes: Beware of Misdiagnosis
A 43-year-old woman was admitted for acute unusual headache, vertigo, and left upper limb weakness. She had been complaining of asthenia for the past few weeks. Her medical history included uterine cervix cancer treated with conisation and 2 pregnancies without serious complications. No allergy or recent drug introduction was noted. After ruling out current pregnancy, magnetic resonance imaging (MRI) was immediately performed and showed recent ischemic strokes in multiple territories. Doppler ultrasound imaging showed no carotid or vertebral arteries lesion. Electrocardiogram showed no ST elevation or atrial fibrillation, ...

Antibiotic-Induced Disruption of Gut Microbiota Alters Local Metabolomes and Immune Responses
In conclusion, our study indicated that 3 weeks antibiotic administration induced elevated expression of many cytokines in mouse colon, suggesting that there might be a direct interaction between antibiotics and host tissue. Furthermore, different antibiotics used can lead to different effects on mouse models. Broad spectrum antibiotic enrofloxacin had a stronger effect on the cytokines response in the colon. Vancomycin can induce significant changes in composition and metabolic profiling of gut microbiota. Compared to enrofloxacin and vancomycin, polymixin B sulfate had a weakest effect. The differences observed in compos...

Focused Ultrasound Improves NK-92MI Cells Infiltration Into Tumors
Conclusion In conclusion, we demonstrated that the combination of FUS and microbubbles could increase the NK-92MI cells’ infiltration into tumors in this study. The combination of FUS and NK-92MI had a much better therapeutic effect when compared with the PBS group, but no superior therapeutic effect when compared with the NK-92MI group. In total, FUS and microbubbles can improve NK cells’ infiltration into tumors, but future work is still needed to improve NK-92MI cells’ delivery efficiency for solid tumor treatment. Ethics Statement This study was carried out in accordance with the recommendations...

Lactobacillus plantarum KLDS1.0318 Ameliorates Impaired Intestinal Immunity and Metabolic Disorders in Cyclophosphamide-Treated Mice
Conclusion In conclusion, the present study showed that the oral administration of L. plantarum KLDS1.0318 normalized the parameters altered by CTX-induced toxicities, strengthening intestinal health by regulating the Th1/Th2 balance, ameliorating the intestinal morphology and improving profiles of intestinal microbiota and metabolism. Therefore, our findings suggested that the administration of L. plantarum KLDS1.0318 could be of significant advantage in reducing intestinal immunity impairment caused by cyclophosphamide. Ethics Statement This study was carried out according to the Animal Care Review Committee, Northeas...

A Diagnostic Dilemma: Sometimes You ’ ll Never Know
Discussion It can be difficult to consider what is the problem when a health care provider is presented with a group of seemingly disparate signs and symptoms with a history and time course that do not match classic (or commonly atypical) disease presentations. Common things happen commonly, so when symptoms occur without the usual co-occurring symptoms, unusual symptoms or time courses, it can be challenging. The provider must develop a reasonable differential diagnosis and balance how far to go with the evaluation against how much to monitor the patient for new signs or symptoms which can provide new information. Patient...

Ultrasound-guided corticosteroid injections for adhesive capsulitis more effective than placebo
Commentary on: Prestgaard T, Wormgoor ME, Haugen S, et al.. Ultrasound-guided intra-articular and rotator interval corticosteroid injections in adhesive capsulitis of the shoulder: a double-blind, sham-controlled randomized study. Pain 2015;156:1683–91. Context Adhesive capsulitis (frozen shoulder or painful stiff shoulder) is relatively common. It is idiopathic: known associated factors include trauma, diabetes, prolonged immobilisation, age, stroke and autoimmune disease. While self-limited, pain and decreased range of motion can last up to 2–3 years. Therefore, there is practical value in therapeutic in...

Digital ulcers predict a worse disease course in patients with systemic sclerosis
Conclusions In patients with SSc, HDU at presentation predicts the occurrence of DUs at follow-up and is associated with cardiovascular worsening and decreased survival.

Pathology of Sarcoidosis
Abstract Pathologists are frequently involved in the diagnosis of sarcoidosis on conventional biopsies or examining bronchoalveolar lavage fluid and assisting bronchoscopists when performing bronchial or transbronchial biopsies or transbronchial needle aspiration (TBNA)/endobronchial ultrasound (EBUS)-guided biopsies of enlarged lymph nodes. Histology generally does not pose difficult tasks in the correct clinical and imaging scenario, but atypical forms of sarcoidosis exist, and in these cases, the diagnosis may become difficult. When faced with granulomas in the lung, the evaluation of their qualitative features...
