Objective: To assess the clinical presentation and evaluation of acute life-threatening chest pain in Accra, Ghana., Design: This was a cross-sectional study at the emergency departments of two leading tertiary hospitals in Accra., Settings: The study was conducted at the Korle-Bu Teaching Hospital and the 37 Military Hospital in Accra., Participants: The study participants comprised adult patients aged 18 years and above who presented with acute chest pain at the emergency departments between April and June 2018., Main Outcome: Acute coronary syndrome is the leading life-threatening cause of chest pain with poor pre- and in-hospital care., Results: 232 patients with chest pain were enrolled as respondents aged 18 to 94 years. The prevalence of life-threatening conditions causing chest pain was 31.9% of those who presented with acute chest pain. These included acute coronary syndrome (82.4%), pulmonary embolism (14.9%), and acute chest syndrome (2.7%). A few (6.6%) with life-threatening conditions such as acute coronary syndrome were transported by ambulances, and 44.3% reported to the facility within 2 to 9 days after the onset of chest pain. None of the patients with pulmonary embolism and acute chest syndrome had computer tomography pulmonary angiogram (CTPA) and echocardiogram done, respectively., Conclusion: Our study found that life-threatening conditions amongst patients presenting with acute chest pains are common; however, there is a need to improve pre-hospital care and in-hospital assessment of these cases., Funding: The study was partly funded by the Medtronic Foundation., Competing Interests: Conflict of interest: None declared, (Copyright © The Author(s).)

Background and Aim: Guillain–Barré syndrome (GBS) is one of the most common causes of acute flaccid paralysis. A timely assessment of this disease condition and its treatments are of vital importance to patients diagnosed with GBS. The purpose of this study is to investigate the variation trend of neutrophils along with disease courses and assess the prognostic value of serum low‐density neutrophils (LDNs) in the acute‐onset and recurrence of GBS. Methods: A total of 176 GBS patients were recruited. Patients were evaluated with Medical Research Council (MRC) sum score and the Hughes Functional Grading Scale score upon admission. Peripheral blood samples were collected for routine testing. Flow cytometry analysis was performed to identify LDNs. All patients were followed up to collect disease condition data. Results: The total neutrophil ratios and counts were significantly higher in patients with acute‐onset GBS compared to healthy controls (HCs). These counts/ratios decreased during remission and re‐elevated in recurrent GBS patients. However, no correlation was observed between the total neutrophil counts/ratios and the MRC sum score. The LDNs collected from different GBS courses were identified using flow cytometry. The counts and ratios were significantly higher in acute‐onset GBS and recurrent GBS compared to HCs and patients in remission. The LDN counts/ratios displayed a negative correlation with the MRC sum scores in acute‐onset GBS and recurrent GBS. Conclusion: Our findings suggest that LDN counts/ratios are positively correlated with the acute‐onset and recurrence of GBS and its severity. Therefore, LDNs might serve as an accessible prognostic indicator for disease progression monitoring. [ABSTRACT FROM AUTHOR]

Superior mesenteric artery (SMA) syndrome is a rare condition caused by compression of the third portion of duodenum by the angle between the superior mesenteric artery against the aorta. A rare presentation of SMA syndrome is following scoliosis repair and spinal fusion with a low incidence and most of these patients present with symptoms within one to two weeks or even more after the surgical repair. A high suspicion index after surgical correction of scoliosis with well-known risk factors (low BMI, low percentile of weight for height, and a high degree of change in the Cobb's angles) can anticipate the postoperative diagnosis. Management has been described for postsurgical scoliosis repair with a late onset presentation of SMA syndrome with nutritional support with good success rates, but there is no data for best treatment management for acute onset especially when the surgical correction of the spine causes complete duodenal obstruction and a surgical intervention might be warranted. Here in, we present a 14 year-old boy with an acute 24-h postoperative SMA syndrome following surgical correction of scoliosis.

Purpose: To describe the clinical characteristics of spontaneous, late-onset comitant acute, nonaccommodative esotropia (ANAET) in children. Materials and Methods: Clinical characteristics of a cohort of patients under 16 years of age with ANAET were studied retrospectively. Results: Of 15 patients eight were females. Mean age was 7.15 years (range 2.5-13, SD 3.34). Mean age of the onset of deviation was 3.2 years (range 1.5-9, SD 2.26). Mean duration of strabismus was 36 months (range 3-132, SD 43). History of a precipitating event was present in five patients (33.3%). Mean cycloplegic refraction was 1.84 diopter sphere (range -5.75 to +7.25, SD 3.55). Mean esodeviation for near and distance fixation was 40 prism diopter (range 15-90, SD 23.9). None had near/distance disparity of more than 5 prism diopter. Amblyopia was present in 13 cases (87%). Strabismus surgery was performed for eight patients. Five patients had orthophoria and three were aligned within 8 prisms esodeviation. Conclusion: ANAET is more common than previously reported, has a variable time of onset and high incidence of amblyopia. Timely management would avert emergence of amblyopia and vertical incomitance thereby promising better binocular outcome.

Background. The mechanism of liver injuries in autoimmune hepatitis (AIH) is not fully understood, especially because the onset is insidious and the clinical courses fluctuate with spontaneous exacerbation and improvement even without immunosuppressive therapies. Methods. Eleven patients with acute-onset AIH, some of whom were without hypergammaglobulinemia or anti-nuclear antibodies, and 41 patients with chronic AIH were compared serologically, biochemically, and histologically to determine differences in liver injuries between patients with acute-onset and chronic AIH. All patients fulfilled the diagnostic criteria according to a scoring system proposed in 1999. Results. Lymphocytes with CD8+/CD25+ markers in pretreatment blood were significantly more prevalent in acute-onset than chronic AIH patients (24% vs 14%; P < 0.05). After treatment, however, CD8+/CD25+ lymphocytes were fewer in patients with acute-onset than in those with chronic AIH at 1 and 2 weeks (P = 0.0001). No other differences were noted in clinical characteristics or immunological parameters between patients with acute-onset and those with chronic AIH. In a patient with typical acute-onset AIH, CD8+/CD25+ lymphocytes increased and decreased in parallel with the activity of liver disease. Conclusions. Activated CD8+ T lymphocytes with CD25 markers may be implicated in the development of acute-onset AIH. [ABSTRACT FROM AUTHOR]

The clinicopathological features of nine acute-onset autoimmune hepatitis (AIH) patients were compared with those of 29 classical AIH patients. The clinical features of acute-onset AIH showed significantly higher serum ALT levels, lower serum IgG levels and AIH score than those of classical AIH, although the type of auto-antibodies, age and gender were not different between the two groups. Pathological features showed that the stages of acute-onset AIH varied from stage 1 to stage 4 and were less advanced compared with those of classical AIH. One patient showed submassive hepatic necrosis. Both centrilobular necrosis and interface hepatitis were observed in 7 and 8 of 9, respectively. Three stage 1 patients with centrilobular necrosis and one patient with submassive hepatic necrosis were suggestive of acute presentation, while patients with stages 2 and 4 fibrosis were suggestive of acute exacerbation of chronic disease. An immunohistochemical study demonstrated that CD8 T cells were predominant at both interface hepatitis and centrilobular necrosis, while CD79α-positive B lineage cells were predominant at interface hepatitis. These results suggest that acute-onset AIH includes both acute presentation and acute exacerbation of chronic disease and that centrilobular necrosis might be a prevailing pathological feature.

A 77-year-old woman developed acute onset of orthostatic hypotension, urinary retention, and constipation. Neurological examination on admission showed severe orthostatic hypotension accompanied by syncope, mydriatic pupils, and attenuation of light reflexes with no abnormalities in other neurological systems. Autonomic testing revealed denervation hypersensitivity in norepinephrine (NE) intravenous infusion test and 0.125% pilocarpine instillation test, low NE in the serum, and decreased amount of sweating in quantitative sudomotor axon reflex test. These findings indicated dysfunction of postganglionic autonomic nerves. Autoimmune autonomic ganglionopathy (AAG) was diagnosed due to the presence of anti-ganglionic acetylcholine receptors. The patient was given intravenous high-dose immunoglobulin therapy (IVIg), improving orthostatic hypotension, urinary retention, and constipation. Previous reports indicated that the response to IVIg varied from case to case. Thus, this case suggests that IVIg is effective in acute-onset AAG cases.

A 63-year-old woman presented to our hospital with sudden symptoms of unsteadiness while walking. Based on the neurological findings, i.e., ataxia and absence of tendon reflex in the extremities accompanied by antecedent infection at the time, she was tentatively diagnosed with Fisher syndrome. Following intravenous immunoglobulin (IVIg) therapy for 5 days, her ataxic symptoms improved. Laboratory data were negative for antiganglioside antibody against GQ1b in the IgG subclass. Six months after her first admission, cognitive impairment gradually developed. She was re-admitted owing to new onset of unsteadiness while walking 1.5 years after her first admission. Diffusion-weighted brain MRI (DWI) revealed linear high-intensity signals in the region of the corticomedullary junction. Cutaneous skin biopsy revealed intranuclear inclusion bodies in sweat gland cells. Considering her family history along with the examination results, we diagnosed with adult-onset sporadic neuronal intranuclear inclusion disease (NIID). Retrospective investigation of the previous DWI obtained at the first admission had also shown slight linear high-intensity areas, suggesting that a series of events, including repeated sudden-onset transient ataxia, resulted due to NIID.
