Spontaneous spinal epidural haematoma mimicking meningitis in a 2-year-old child--a case report and literature review

INTRODUCTION

We report the case of a 2-year-old boy with suspected meningitis who presented with acute onset neck pain and stiffness associated with right-sided weakness and ataxia.

MANAGEMENT

Despite intravenous antibiotics and antiviral treatment, his condition deteriorated. Magnetic resonance imaging demonstrated spontaneous cervical epidural haematoma (C4-C7) extending down to thoracic (T7) level with associated compression of the spinal cord. He was treated successfully by neurosurgical decompression and made a complete recovery.

DISCUSSION

Spinal epidural haematoma is a neurosurgical emergency characterised by extravasation of blood in the spinal epidural space. The clinical presentation particularly in young children can masquerade other conditions such as meningitis. In this article, we discuss our case and review the literature on spontaneous spinal epidural hematoma with an aim to improve awareness of this condition which if not recognised and treated early can lead to significant lifelong morbidity.

Human papillomavirus is detectable in Barrett's esophagus and esophageal carcinoma but is unlikely to be of any etiologic significance

Barrett's esophagus (BE), a known precursor of esophageal adenocarcinoma has recently been associated with human papillomavirus (HPV). p16(INK4a) expression is a recognized surrogate marker of HPV infection in the cervix.

OBJECTIVES

This study has assessed the possible role of human papillomavirus (HPV) infection in BE and esophageal adenocarcinoma, in the North American population by screening esophageal tissues for HPV by a combination of assays.

STUDY DESIGN

Formalin-fixed, paraffin-embedded blocks from cases of Barrett's esophagus (n=84), esophageal adenocarcinoma (n=36) and normal gastro-esophageal junction (n=29) were examined for HPV by PCR, chromogenic in situ hybridization, and p16(INK4a) immunohistochemistry.

RESULTS

HPV DNA was detected by PCR in 23 of 84 (27.4%) BE cases, 11 of 36 (31%) cases of adenocarcinoma and in 7 of 29 (24%) normal control cases (p=0.82). p16(INK4a) staining was positive in 10 (12%) cases of BE, 15 (42%) cases of adenocarcinoma and 6 (21%) cases of the control group. Positive p16(INK4a) staining was not statistically different between the three groups whether positive or negative for HPV DNA (p=0.91 and p=0.91 respectively). Similarly, negative p16(INK4a) staining did not show a difference between the three groups for whether positive or negative for HPV DNA (p=0.50 and p=0.28, respectively). HPV was not detected by CISH in the adenocarcinomas while in BE and control groups, CISH was non-contributory.

CONCLUSIONS

These data suggest that while HPV is detectable in a subset of esophageal lesions and tumors, the HPV detected is unlikely to be of etiologic significance or a factor accounting for the increase in BE and esophageal adenocarcinoma cases in the United States.

A structured course teaching junior doctors invasive medical procedures results in sustained improvements in self-reported confidence

Pressure on working hours has led to a decrease in opportunities for training in invasive medical procedures for junior doctors. The effect of a structured course on immediate and medium-term changes in self-reported confidence was investigated. A one-day model-based practical course was run on two separate occasions teaching central venous line placement, lumbar puncture, Seldinger-technique chest drain insertion and knee joint aspiration. Attendees were asked to indicate their confidence in each procedure on a 10-point Likert scale before, immediately after and three months after the course. Significant improvements in self-reported confidence were seen for all procedures which were sustained at three months. Feedback was universally positive. Practical preclinical training may be a useful adjunct to patient-based training in invasive procedures. The course was particularly popular with foundation year trainees: ideally this training should be available before trainees' first exposure in the clinical setting.

Expression pattern of miR-146a, an inflammation-associated microRNA, in experimental and human temporal lobe epilepsy

Increasing evidence supports the involvement of inflammatory and immune processes in temporal lobe epilepsy (TLE). MicroRNAs (miRNA) represent small regulatory RNA molecules that have been shown to act as negative regulators of gene expression controlling different biological processes, including immune-system homeostasis and function. We investigated the expression and cellular distribution of miRNA-146a (miR-146a) in a rat model of TLE as well as in human TLE. miR-146a analysis in rat hippocampus was performed by polymerase chain reaction and immunocytochemistry at 1 week and 3-4 months after induction of status epilepticus (SE). Prominent upregulation of miR-146a activation was evident at 1 week after SE and persisted in the chronic phase. The miR-146a expression was confirmed to be present in reactive astrocytes. In human TLE with hippocampal sclerosis, increased astroglial expression of miR-146a was observed mainly in regions where neuronal cell loss and reactive gliosis occurred. The increased and persistent expression of miR-146a in reactive astrocytes supports the possible involvement of miRNAs in the modulation of the astroglial inflammatory response occurring in TLE and provides a target for future studies aimed at developing strategies against pro-epileptogenic inflammatory signalling.

The intersections of gender and class in health status and health care

It is increasingly recognized that different axes of social power relations, such as gender and class, are interrelated, not as additive but as intersecting processes. This paper has reviewed existing research on the intersections between gender and class, and their impacts on health status and access to health care. The review suggests that intersecting stratification processes can significantly alter the impacts of any one dimension of inequality taken by itself. Studies confirm that socio-economic status measures cannot fully account for gender inequalities in health. A number of studies show that both gender and class affect the way in which risk factors are translated into health outcomes, but their intersections can be complex. Other studies indicate that responses to unaffordable health care often vary by the gender and class location of sick individuals and their households. They strongly suggest that economic class should not be analysed by itself, and that apparent class differences can be misinterpreted without gender analysis. Insufficient attention to intersectionality in much of the health literature has significant human costs, because those affected most negatively tend to be those who are poorest and most oppressed by gender and other forms of social inequality. The programme and policy costs are also likely to be high in terms of poorly functioning programmes, and ineffective poverty alleviation and social and health policies.

Serum levels of interferon-gamma, tumour necrosis factor-alpha, soluble interleukin-6R and soluble cell activation markers for monitoring response to treatment of leprosy reactions

Identifying pathogen and host-related laboratory parameters are essential for the early diagnosis of leprosy reactions. The present study aimed to clarify the validity of measuring the profiles of serum cytokines [interleukin (IL)-4, IL-6, IL-10, interferon (IFN)-gamma and tumour necrosis factor (TNF)-alpha], the soluble IL-6 receptor (sIL-6R), soluble T cell (sCD27) and macrophage (neopterin) activation markers and Mycobacterium leprae-specific anti-PGL-I IgM antibodies in relation to the leprosy spectrum and reactions. Serum samples from 131 Indonesian leprosy patients (82 non-reactional leprosy patients and 49 reactional) and 112 healthy controls (HC) from the same endemic region were investigated. Forty-four (89.8%) of the reactional patients had erythema nodosum leprosum (ENL) while only five (10.2%) had reversal reaction (RR). Follow-up serum samples after corticosteroid treatment were also obtained from 17 of the patients with ENL and one with RR. A wide variability in cytokine levels was observed in the patient groups. However, IFN-gamma and sIL-6R were elevated significantly in ENL compared to non-ENL patients. Levels of IFN-gamma, TNF-alpha and sIL-6R declined significantly upon corticosteroid treatment of ENL. Thus, although the present study suggests limited applicability of serial measurement of IFN-gamma, TNF-alpha and sIL-6R in monitoring treatment efficacy of ENL, reactions it recommends a search for a wider panel of more disease-specific markers in future studies.

Unusual foreign body (broken tracheostomy tube) in left main bronchus

Foreign bodies in the tracheobroncial tree are commonly seen in children and less so in adults. All manners of materials have been described as accidentally entering the tracheobroncial tree. Although tracheostomy tube as a foreign body in tracheobroncial tree is not so common, it is still well known. They present as emergencies and require skillful management. Few cases of tracheotomy tube in the tracheobrochial tree. have been reported in the literature till date. We have some across such case of broken fuller's tracheostomy tube (flange) in left main broncus and mwe are reporting this casedue to its rarity.
