Dental tissue-derived mesenchymal stem cell (MSC)-mediated tooth regeneration may be a useful therapeutic tool for repairing tooth loss. However, the low success rate of tooth regeneration restricts its clinical application. Identifying key factors for enhancing dentinogenesis in MSCs is crucial for promoting tooth regeneration.

Human dental pulp stem cells (DPSCs) were transfected with retrovirus to obtain SFRP2-over-expressing DPSCs. Alkaline phosphatase (ALP) activity assay, Alizarin red staining, quantitative analysis of calcium, and dentinogenesis-related genes were detected. Additionally, transplantation in a rabbit tooth extraction model was used to explore the role of SFRP2 in dentin regeneration.

We found SFRP2 over-expression greatly enhanced ALP activity, and mineralization in DPSCs. Real-time RT-PCR revealed SFRP2 over-expression promoted the expressions of OSX, RUNX2, DSPP, DMP1, and BSP. Moreover, Micro CT analysis showed high-density calcification occurred to a much higher extent in SFRP2 over-expressing group compared to control group in vivo. find more Additionally, HE staining, immmunohistochemistry staining, and scanning electron microscopy results showed much more dentin-like tissue formed in SFRP2 over-expressing group compared to control group.

Our findings revealed SFRP2 is an important regulator that enhances the dentinogenesis of DPSCs and dentin regeneration in the jaw, which may have clinical applications.

Any type of cutaneous metastasis indicates dismal outcome of the disease. Skin is an unusual location for metastatic deposits from any tumour and has an incidence of about 0.8%-5%. Fine needle aspiration cytology (FNAC) helps in the rapid diagnosis of metastasis with minimum pain.

To study the cytomorphological spectrum of cutaneous metastasis on FNAC.

A total of 225 patients withdiagnosis of cutaneous metastasis on cytology were analysed. May-Grünwald Giemsa and haematoxylin-eosin-stained smears were studied and examined for the cytomorphological spectrum of cutaneous metastasis. Cell block was prepared in a few cases. In a subset of cases, immunohistochemistry was done to pinpoint the primary.

Amongst the 225 patients studied, the mean age was 53.9years. There was female preponderance with 125 females and 100 males. The commonest site was abdominal wall (n=89) followed by chest wall (n=60). The most common type of metastasising tumour was adenocarcinoma.

Clinicians and pathologists must be aware of the clinico-morphological spectrum of cutaneous metastasis for instant diagnosis followed by prompt management.

There are many causes of facial nerve palsy. The most common causes are neuroborreliosis (NB), idiopathic paralysis or Herpes simplex virus (HSV) reactivation. The aim of this study was to characterize patients with facial palsy in the course of NB and to determine whether HSV-1 reactivation takes place during the acute phase of NB.

A retrospective analysis of 66 patients with facial nerve palsy was performed. In 38 patients, facial palsy was caused by Borrelia burgdorferi sl infection. Immunological tests for HSV-1, tick-borne encephalitis virus and B burgdorferi sl in serum and cerebrospinal fluid (CSF) were performed.

In this analysis, 55.2% of NB patients had right nerve palsy and 21% bilateral palsy; 15.8% of patients had erythema migrans (EM). Lymphocytic meningitis was diagnosed in 92% of patients and Bannwarth's syndrome was diagnosed in 47% of patients. IgM anti-HSV-1 antibodies were detected in four patients with NB and two patients with facial nerve palsy of other origin. IgM anti-HSV-1 antibodies were detected in the CSF of three patients (7.9%) with NB, and one of them had bilateral VII paresis and EM simultaneously. Treatment with ceftriaxone or doxycycline led to complete recovery.

Neuroborreliosis should always be considered as a cause of peripheral facial nerve palsy. Peripheral facial nerve palsy is a significant symptom in the course of NB, especially in patients accompanied by meningitis. Pathomechanism of facial nerve paresis has not been well explained so far and may depend on two independent mechanisms in NB, including HSV-1 reactivation.

To investigate whether there are common clinical findings in bacteraemic children that were discharged from the emergency department (ED) and to follow their clinical outcome.

A retrospective chart review of children above one-month-old with positive blood cultures obtained in Shamir Medical Center's ED between January 2011 and December 2019 was conducted.

A total of 250 cases were analysed, of which 68 discharged after first evaluation. Streptococcus pneumonia was the most commonly isolated pathogen. Compared to children that were admitted when first evaluated in the ED, discharged children had lower C-reactive protein (mean 50.5±62.8 vs 121.7±113.2mg/L, p<0.001). Dyspnoea and being ill-looking were less prevalent among the latter (6.7% versus 35.1%, p=<0.001, 3.0% versus 22.2% p<0.001, respectively), as were presence of Kingella kingae and other Gram-negative bacteria. Of the children hospitalised in our institution, the duration of hospitalisation was significantly lower than in those admitted during the first visit (6.3±4.3 vs 9.0±7.4days, p=.002). None of the discharged children were admitted to paediatric intensive care unit.

Children with bacteraemia who were discharged home before knowing their positive blood cultures results had lower C-reactive protein and better outcome compared to those admitted on first evaluation in emergency department.
