There is a need for the development of effective baselines against which the water quality impacts of new developments can be assessed. The specific conductance of flowback water from shale gas operations is typically many times the specific conductance of surface water and near-surface groundwater. This contrast in specific conductance means that specific conductance could be the ideal determinand for detecting water quality impacts from shale gas extraction. If specific conductance is to be used for detecting the impacts of shale gas operations, then a baseline of specific conductance in water bodies is required. Here, Bayesian hierarchical modelling of specific conductance was applied across English groundwater. The modelling used existing, spot-sampled data from the years 2000 to 2018 from 537 unique borehole locations. When the differences between boreholes was considered, then the approach was sufficiently sensitive to detect 1% mixing of fracking fluid in groundwater at a 95% confidence interval. The Bayesian hierarchical modelling maximises the return on public investment and provides a means by which future observations can be judged.
Combined central and peripheral demyelination (CCPD) is a term used to describe a rare condition involving demyelinating lesions of both the central and the peripheral nervous system. Its etiology remains unclear, and a pathogenic role of cell-mediated and/or humoral immunity has been proposed. A number of patients with CCPD are positive to antineurofascin (anti-NF), antigalactocerebroside, and antilactosylseramide antibodies. The relation between CCPD and multiple sclerosis (MS) is unclear.

We report the case of a 30-year-old man who was referred for evaluation after having episodes of numbness and gait impairment worsened by intravenous Methylprednisolone and was found to have demyelination in both central and peripheral nervous system. The patient was eventually diagnosed with anti-NF 155 CCPD and received multiple courses of intravenous immunoglobulin without significant improvement, while he remained stable under Rituximab. read more Interestingly, the patient's father suffered from a mild form of relapsing remitting MS.

Our case emphasizes that clinicians need to keep in mind the possibility of a coexisting demyelination in both central and peripheral nervous system, even in patients with a family history of MS. The need for a timely diagnosis is imperative since several drugs used in the management of MS can worsen the patient's symptoms in CCPD. This is, to our knowledge, the first reported case of a patient with anti-NF 155 positive CCPD and a family history of MS.

Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is a rare variation of internuclear ophthalmoplegia associated with bilateral lesions of the medial longitudinal fasciculus.

In this case, the edematous lesions of the ipsilateral midbrain infarction appeared to compress the contralateral medial longitudinal fasciculus, resulting in WEBINO. Treatment of focal cerebral edema caused by ischemic stroke is still under debate. However, in this case, antiedema treatment was implemented to prevent the sequelae of the edematous lesion caused by a midbrain infarction, and a relatively rapid improvement of ocular symptoms was observed.

Herein, we report a rare case of WEBINO caused by a unilateral midbrain infarction in which the patient experienced edema-related neurological deficits. This case provides evidence that early antiedema therapy may benefit patients with similar presentations.

Parkinsonism-hyperpyrexia syndrome (PHS) is a rare and potentially fatal complication of Parkinson disease (PD) characterized by a neuroleptic malignant-like syndrome due to abrupt discontinuation of antiparkinsonian medications.

A 79-year-old woman with late-stage PD presented at the hospital with neuropsychiatric and uncontrolled parkinsonian motor symptoms. Soon after the abrupt discontinuation of amantadine, the patient suddenly presented with global rigidity, global unresponsiveness, diaphoresis, tachycardia, recurrent hyperpyrexia, and a mildly elevated creatine kinase, which lead to the diagnosis of PHS. Amantadine was then reinitiated and her symptoms resolved within 10 days.

Amantadine is an antiparkinsonian medication scarcely associated with PHS. The few reported cases are further summarized and discussed in this article. This case highlights the importance of early recognition of PHS, which may be caused by changes in other antiparkinson agents such as amantadine, and the need to slowly titrate such agents.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome, is a multisystemic entity of mitochondrial inheritance. To date, there is no epidemiological information on MELAS syndrome in Mexico.

A retrospective, cross-sectional design was employed to collect and analyze the data. The clinical records of patients with mitochondrial cytopathies in the period ranging from January 2018 to March 2020 were reviewed. Patients who met definitive Yatsuga diagnostic criteria for MELAS syndrome were included to describe frequency, clinical, imaging, histopathologic, and molecular studies. Of 56 patients diagnosed with mitochondrial cytopathy, 6 patients met definitive Yatsuga criterion for MELAS (10.7%). The median age at diagnosis was 34 years (30 to 34 y), 2 females and the median time from onset of symptoms at diagnosis 3.5 years (1 to 10 y). The median of the number of stroke-like episodes before the diagnosis was 3 (range, 2 to 3). The main findings in computed tomography were basal ganglia calcifications (33%), whereas in magnetic resonance imaging were a lactate peak in the spectroscopy sequence in 2 patients.
