AbstractIn this article, we described a case of pathogen-induced bilateral optic neuritis accompanying meningococcal meningoencephalitis in an adolescent male. A 15-year-old boy presented to our emergency room due to progressive severe headache, stiff neck, diffuse extremity pain, fever, and nausea concerning meningoencephalitis. Intravenous ceftriaxone, metamizole, and ondansetron were started immediately. Due to acute autonomic dysregulation and development of petechiae, he was transferred to the pediatric intensive care unit. Next morning, the patient developed severe visual impairment. Investigations revealed elevated C-reactive protein, procalcitonin and leucocyte count, decreased platelet count, and clotting activation. Cerebrospinal fluid (CSF) analysis revealed increased leucocyte count, protein, and decreased glucose concentration with pathological CSF cytology. Brain magnetic resonance imaging revealed an increased contrast enhancement in the optic nerve sheath, consistent with acute bilateral optic neuritis. He was started on high-dose intravenous pulse methylprednisolone therapy. After treatment with ceftriaxone und pulse steroids, the patient was discharged in good condition without any visual sequel.

Abstract Introduction Streptococcal myositis is a rare form of infectious myositis caused by Lansfield A beta-haemolytic streptococci. It is characterised by rapidly spreading inflammation that can result in severe systemic toxicity and necrosis of the affected tissue if not diagnosed and aggressively treated. Presentation We report a case of a 42-year-old male who presented with a one-week history of worsening right axillary swelling that progressed to painful swelling of his arm. Inflammatory markers were significantly elevated with a white cell count of 17 ×109/L and C-reactive protein of 212 mg/L. On examination, a fluctuant axillary swelling was appreciated, and a decision was made for incision and drainage under general anaesthetic. Intraoperative aspiration of his arm revealed copious purulent fluid prompting intraoperative orthopaedic consult and exploration of the anterior compartment in which there was extensive involvement of the biceps muscle. The microbiological analysis revealed gram-positive cocci in chains, and microbiology advice sought for tailoring of antibiotic regimen. He has recovered well. Discussion Though uncommon, the emergency general surgeon should have a high degree of suspicion when evaluating soft tissue infections to avert potentially disastrous outcomes. Conclusion Early diagnosis, aggressive management with high-dose intravenous antibiotics, and surgical debridement are principles to treat this rare, life-threatening infection.

Background:Optic Neuritis (ON) is one of the most common clinically isolated syndromes which develops into clinically diagnosed Multiple Sclerosis (CDMS) over time.Objective:To assess the conversion rate of Iranian patients presenting with idiopathic ON to CDMS as well as monitoring potential demographic and clinical risk factors.Methods:Atotal of 219 patients' medical records of idiopathic ON from March 2001 to May 2009 were reviewed. Demographic findings, ophthalmologic characteristics on admission and discharge, diagnostic approaches, type and dosage of therapy were retrospectively reviewed. A structured telephone interview was then conducted to identify patients who had subsequently been diagnosed with MS. Survival analysis was used to evaluate the cumulative probability of MS conversion and contributory risk factors.Results:From the 219 ON patients, 109 [age 11-51, female: 81%] were followed up. Among the male gender the mean age of patients developing MS was significantly lower (P=0.01). In cox regression model, female sex (p=0.07), bilateral ON (p=0.003), MRI abnormalities (p <0.001) and high dose (5g) corticosteroid therapy (p<0.001) were identified as risk factors for the development of MS. The two and five year cumulative probability of developing MS were 27% and 45%, respectively.Conclusions:Idiopathic ON in Iranian patients carries higher risk of progression to MS compared to other Asian countries. MRI lesions are the strongest independent risk factor of developing CDMS. Bilateral ON, female gender and high dose corticosteroid therapy are also important factors in predicting CDMS development.

Neurolisteriosis is a foodborne infection of the central nervous system that is easily misdiagnosed, especially in healthy adults with atypical symptoms. A 50-year-old man presented with a 3-day history of distortion of the oral commissure. Facial neuritis was diagnosed and treated with intravenous dexamethasone. His condition deteriorated rapidly, and he presented with a slow pharyngeal reflex, stiff neck, and signs of peripheral facial paralysis. Brain magnetic resonance imaging revealed multiple ring-enhanced foci in the brainstem. Routine and biochemical cerebrospinal fluid (CSF) analyses showed increased white blood cells and microproteins. Blood culture and high-throughput genome sequencing revealed Listeria monocytogenes DNA in the CSF. Ampicillin, amikacin, and meropenem were administered, and the patient was transferred from the intensive care unit to a standard medical ward after 2 months. The patient could walk and eat normally; however, he required intermittent mechanical ventilation at 11 months after discharge. Although L. monocytogenes meningitis is rare in healthy immunocompetent adults, it must be considered as a differential diagnosis, especially in adults whose conditions do not improve with cephalosporin antibiotic administration. L. monocytogenes rhombencephalitis mimics facial neuritis and develops quickly. Prompt diagnosis is essential for rapid initiation of antibiotic therapy to achieve the best outcome.

Lasiopodomys Brandtii

Gallic acid (GA), a phenol that is present in various plants, potentially contains antioxidant properties. This study aimed to investigate the effects of GA on the reproduction of adolescent male Brandt’s voles (Lasiopodomys brandtii (Radde, 1861)). Antioxidant levels and apoptosis in the testis, as well as reproductive physiology, were evaluated in adolescent males treated with GA. The results showed that a low dose of GA enhanced relative epididymis weight and the sperm density in the epididymis, increased the mRNA levels of steroidogenic acute regulatory protein in the testis, and reduced the percentages of abnormal and dead sperm. In addition, a low dose of GA significantly increased the levels of superoxide dismutase, catalase, and glutathione peroxidase, and decreased the level of malondialdehyde in the testis, as well as the mRNA and protein levels of the apoptosis related gene, caspase-3. However, a high dose of GA sharply reduced the average diameter of the seminiferous tubules compared to a low dose. Collectively, these findings demonstrate that GA treatment during puberty affects the reproductive responses of male Brandt’s voles in a dose-dependent manner by regulating antioxidant levels and apoptosis.

The endocannabinoid system is responsible for regulating a spectrum of physiological activities and plays a critical role in the developing brain. During adolescence, the endocannabinoid system is particularly sensitive to external insults that may change the brain’s developmental trajectory. Cannabinoid receptor type 2 (CB2R) was initially thought to predominantly function in the peripheral nervous system, but more recent studies have implicated its role in the mesolimbic pathway, a network largely attributed to reward circuitry and reward motivated behavior, which undergoes extensive changes during adolescence. It is therefore important to understand how CB2R modulation during adolescence can impact reward-related behaviors in adulthood. In this study, adolescent male rats (postnatal days 28–41) were exposed to a low or high dose of the CB2R antagonist/inverse agonist SR144528 and Pavlovian autoshaping and instrumental conditional behavioral outcomes were measured in adulthood. SR144528-treated rats had significantly slower acquisition of the autoshaping task, seen by less lever pressing behavior over time [F(2, 19) = 5.964, p = 0.010]. Conversely, there was no effect of adolescent SR144528 exposure on instrumental conditioning. These results suggest that modulation of the CB2R in adolescence differentially impacts reward-learning behaviors in adulthood.

Acute Infectious Disease

Coronavirus disease 2019 (COVID-19) is an acute infectious disease that caused the emergence of the new serious global pandemic. The infection in children is much less prevalent than in adults and most cases are asymptomatic or have mild symptoms. Severe cases represent less than 1% of the total, therefore information about the disease in this age group is scarce compared to data in older individuals. We exposed a case of a 16-year-old male adolescent with a previous diagnosis of myelomeningocele, hydrocephalus with peritoneal ventricle bypass (PVB), recurrent urinary tract infection, epilepsy, and obesity. The patient presented cough and convulsive crises, which worsened during hospitalization with severe acute respiratory syndrome due to SARS-CoV-2, septic shock, and cardiorespiratory arrest and invasive mechanical ventilation (IMV) for 9 days was required. Also presented several other complications and factors of critical prognosis, such as elevated inflammatory markers (C-reactive protein, D-dimer), elevated cardiac troponin, and the necessity of renal replacement therapy. Nevertheless, the clinical outcome was satisfactory and he was discharged after a 40-day stay in the Pediatric Intensive Care Unit.

The Impact

The impact of Covid-19 pneumonia caused by SARS-CoV-2 on transplanted populations under chronic immunosuppression seems to be greater than in normal population. Clinical management of the disease, particularly in those patients worsening after a cytokine storm, with or without allograft impairment and using available therapeutic approaches in the absence of specific drugs to fight against the virus, involves a major challenge for physicians. We herein provide evidence of the usefulness of high-dose intravenous immunoglobulin (IVIG) combined with steroid pulses to successfully treat a case of Covid-19 pneumonia in a single-kidney transplanted patient with mechanical ventilation and hemodialysis requirements in the setting of a cytokine storm. A rapid decrease in the serum level of inflammatory cytokines, particularly IL-6, IL-8, TNF-α, MCP-1 and IL-10, as well as of acute-phase reactants such as ferritin, D-dimer and C-reactive protein was observed after the IVIG infusion and methylprednisolone bolus administration with a parallel clinical improvement and progressive allograft function recovery, allowing the patient’s final discharge 40 days after the treatment onset. The immunomodulatory effect of IVIG together with the anti-inflammatory and immunosuppressive potential of steroids could be an alternative strategy to treat severe cases of Covid-19 pneumonia associated with an uncontrolled inflammatory response in transplanted populations.

Neonatal septicemia is a clinical syndrome of systemic illness accompanied by bacteremia occuring in the first 28 days of life. Neonatal septicemia is one of the major causes of neonatal death in developing countries. Early diagnosis and treatment can prevent neonatal mortality and morbidity. The present study includes: 1) usefulness of CRP (C-reactive protein), Total Leucocyte Count, Platelet Count and Blood Culture in early diagnosis of Neonatal Sepsis, 2) significance of serial CRP in diagnosis of neonatal sepsis. 3) the prognostic value of CRP in neonatal sepsis. This is a prospective study done in neonatal ward, Chittagong Medical College Hospital and carried out from January 2008 to January 2011. Sample size was 300. One hundred fifty neonates with suspected sepsis as cases and 150 healthy babies as control were enrolled in this study. Seventy two percent of cases neonates were preterm and low birth weight. Common risk factors for neonatal septicemia which were identified in this study; preterm (72%), low birth weight (72%), premature rupture membrane (60%), chorioamnionitis (26%) and maternal urinary tract infection (16%) . Out of 150 cases of suspected neonatal sepsis total 80.7%% had raised CRP, in initial sample 70.39% were CRP positive and in 2nd sample additional 9.31% case were CRP positive . In control group 91% were CRP negative. CRP was positive in 100% of culture proven sepsis. Sensitivity of CRP was 80.67% and specificity of CRP was 76.44%. Leucocytosis was observed in 7% of cases and leucopenia was found in 11% of cases. In 82 % cases leucocyte count was found normal. In control group, 95% had normal leucocyte count and 5% had leucocytosis but no leucopenia. Sensitivity of leucocyte count was 18% and specificity was 20.68%. Thrombocytopenia was found in 28% of case group. Out of 150 cases only 15.33% yielded growth of organisms in blood culture. Klebsiella was the most common pathogen isolated which was followed by E.coli and Strph. aureus. Sensitivity of blood culture was 15.33% and specificity was 100% Therefore serial CRP can be taken as alternative method for diagnosis of neonatal sepsis specially in developing countries where blood culture is not readily available.J Bangladesh Coll Phys Surg 2014; 32: 61-65

Abstract BACKGROUNDRacial/Ethnic minorities are at higher risk for Severe COVID-19. This may be related to social determinants that lead to chronic inflammatory states. The aims of the study were to determine if there are racial/ethnic differences between the inflammatory markers of survivors and non-survivors and if there was a dose dependent association of methylprednisolone to in hospital survival. METHODSThis was a secondary analysis of a retrospective cohort. Patients were older than 18 years of age and admitted for severe COVID-19 Pneumonia Between March to June 2020 in 13 Hospitals in New Jersey, United States. Comparison of inflammatory markers used Kruskal-Wallis followed by pairwise comparison using two-sided Wilcoxon rank sum test. A Youden Index Method was used to determine the cut-off between low dose and high dose methylprednisolone. For each racial/ethnic group, cox regression was used to determine the association to survival between no methylprednisolone and methylprednisolone (high dose versus low dose). RESULTSPropensity matched sample (n=759) between no methylprednisolone (n=380) and methylprednisolone (n=379) had 338 Whites, 102 Blacks, 61 Asian/Indians, and 251 Non-Black Non-White Hispanics. Interleukin-6, C-reactive protein, ferritin, and d-dimer values were higher in non-survivors compared to survivors except in Asian/Indian survivors who had higher ferritin values compared to non-survivors (median: 1,265 vs 418 ug/L, P=0.0211). Black and Hispanic survivors had persistently elevated C-reactive protein, (10.2 mg/mL) and (13.70 mg/mL) respectively. Low dose methylprednisolone was associated with prolonged 60 days in hospital survival over no methylprednisolone in Whites (P<0.0001), Asian/Indians (P=0.0180), and Hispanics (P=0.0004). Regardless of dose, methylprednisolone was not associated with prolonged survival in Blacks. High dose methylprednisolone was associated with worse survival in Hispanics. (P=0.0181). CONCLUSIONRacial/Ethnic disparities with inflammatory markers in survivors and non-survivors preclude the use of one marker as predictor of survival. Low dose methylprednisolone is associated with prolonged survival in Asian/Indians, Hispanics, and Whites. Methylprednisolone, regardless of dose, was not associated with prolonged survival in Blacks.
