Hemifacial Spasms

A 30-year-old male American football player presented to the acute medical unit with left-hand and hemifacial spasms. History and examination revealed hemifacial spasms in keeping with seizure-like activity possibly due to symptomatic hypocalcaemia. Subsequent investigations revealed an adjusted calcium of 1.87 mmol/L and, hence, he was managed with intravenous calcium replacement. He presented two further times in a 1-month period, with subjective limb weakness, despite normal adjusted calcium. During his third admission, he developed slurred speech and a marked facial droop, with absence of power in the right upper limb. Imaging revealed acute and old infarctions in the left middle cerebral artery territory and appearances consistent with left internal carotid artery dissection. This presentation of arterial stroke is atypical but with potentially grave consequences if missed. There is limited literature on the presentation of hemifacial spasm, and its association with ischaemic or haemorrhagic stroke represents a key learning point.

Abstract For nuclei which have a nuclear spin of 5/2 and exhibit a small asymmetry parameter of the electric field gradient (ƞ) at the nuclear site, line shapes of the Powder Zeeman NQR (PZNQR) spectra based on the transition between the energy levels m1 = ± 1/2 and ± 3/2 (the lower frequency line) were studied by means of computer simulations and experiments. (i) When an ƞvalue is very small (type 1; ƞ= 0), the line shape exhibits two shoulders like the style of the American football player. (ii) While an ƞvalue is small (type 2; 0 < ƞ< around 0.01) but not zero, the line shape has two small peaks which are symmetrically located on the shoulders, as in the case of the small ƞtype of spin 3/2. (iii) When an ƞvalue is not small (type 3; around 0.01 < ƞ), the line shape has two symmetrical dips in stead of the peaks, which are also similar to the case of not small ƞ type of spin 3/2. As the ƞvalue increases from around 0.01, the two dips grow and reach the maximum at the ƞvalue of 0.349, and then become smaller and obscure in the range of ƞlarger than 0.349.The observations of PZNQR spectra were performed for several compounds including the 127I and/or 121Sb nuclei to estimate the ƞvalues, and gave the results as follows: very small for 127I (207.683 and 209.133 MHz, at 77 K) in Snl4; very small for 127I (176.496 and 177.438 MHz, at 77 K) in Gal3; small for 127I (265.102 MHz, at 77 K) in CH3I; 0.33 for 127I (247.69 MHz, at 77 K) in C2H5I; 0.27 for 121Sb (58.23 MHz, at 290 K) in SbCl3. The estimated ƞvalues were compared to those obtained from the frequencies of two NQR lines for spin 5/2. They were in good agreement with each other for the small region of ƞ, though somewhat large disagreements were seen in the cases of not small ƞvalues.

Abstract Currently, only presumptive diagnosis of chronic traumatic encephalopathy (CTE) can be made in living patients. We present a modality that may be instrumental to the definitive diagnosis of CTE in living patients based on brain autopsy confirmation of [F-18]FDDNP-PET findings in an American football player with CTE. [F-18]FDDNP-PET imaging was performed 52 mo before the subject's death. Relative distribution volume parametric images and binding values were determined for cortical and subcortical regions of interest. Upon death, the brain was examined to identify the topographic distribution of neurodegenerative changes. Correlation between neuropathology and [F-18]FDDNP-PET binding patterns was performed using Spearman rank-order correlation. Mood, behavioral, motor, and cognitive changes were consistent with chronic traumatic myeloencephalopathy with a 22-yr lifetime risk exposure to American football. There were tau, amyloid, and TDP-43 neuropathological substrates in the brain with a differential topographically selective distribution. [F-18]FDDNP-PET binding levels correlated with brain tau deposition (rs = 0.59, P = .02), with highest relative distribution volumes in the parasagittal and paraventricular regions of the brain and the brain stem. No correlation with amyloid or TDP-43 deposition was observed. [F-18]FDDNP-PET signals may be consistent with neuropathological patterns of tau deposition in CTE, involving areas that receive the maximal shearing, angular–rotational acceleration–deceleration forces in American football players, consistent with distinctive and differential topographic vulnerability and selectivity of CTE beyond brain cortices, also involving midbrain and limbic areas. Future studies are warranted to determine whether differential and selective [F-18]FDDNP-PET may be useful in establishing a diagnosis of CTE in at-risk patients.

Abstract. This case of ascending paralysis, following an episode of diarrhea, was initially misinterpreted as Guillain-Barré syndrome. The prominent hypokalemia led to the search for other differential diagnoses, initially interpreted as a rare case of periodic hypokalemic paralysis, which usually occurs in Asians after intake of large amounts of starch foods, such as Spaghetti, or rest after heavy exercise. In this case, the reason for the hypokalemia with associated paralysis was caused by a hyperhyreosis factitia through denied intake of T3.

An emerging field of research views Corporate Political Advocacy (CPA) as a communication strategy that responds to the challenges of public relations in divided societies. CPA takes a political position in public and, by doing so, appears to deliberately alienate some of its stakeholders. This study challenges the assumption that CPA discards a unifying epideictic rhetoric in favour of agonistic politics. The investigated case is Nike’s Dream Crazy campaign starring American football player Colin Kaepernick, whose protest against race discrimination in the United States sparked a heated public debate. Although the critical analysis of the campaign and responses on Twitter reveal deep political cleavages, Nike is concurrently engaged in unchallenged communication praising the hyper-individualism of a market ideology. The epideictic contingency of Nike’s CPA undermines the social cause ostensibly at the heart of the campaign: the fight against racial discrimination.
