ABSTRACT

Introduction: Previous studies have reported a correlation between a high-grade CMV-infection and an unfavorable prognosis in glioblastoma (GB). Coversely, epilepsy has been associated with a more favorable outcome in GB patients. Despites epilepsy and CMV share similar molecular mechanisms in GB tumoral microenvironment, the correlation between Tumor-Related-Epilepsy (TRE) and CMVinfection remains unexplored. The aim of our study is to examine the correlation between the dregree of CMV infection and seizure types on the survival of TRE Adult-type-diffuse-glioma. To achieve this objective, we conducted a comprehensive literature review to assess our results regarding previous publications. Methods: We conducted a retrospective-observational study on TRE Adult-type-diffuse-gliomas treated at a single center in Mexico from 2010 to 2018. Tumor tissue and cDNA were analyzed by immunochemistry (IHC) for CMV (IE and LA antigens) at the Karolinska Institute in Sweden, and RT-PCR for CMV-gB in Torreon Mexico, respectively. Bivariate analysis (X2-test) was performed to evaluate the association between subtypes of Adult-type-diffuse-glioma (IDH-mut grade 4 astrocytoma vs. IDH-wt glioblastoma) and the following variables: type of hemispheric involvement (mesial vs. neocortical involvement), degree of CMV infection (<25%vs. >25% infected-tumoral cells) and seizure types [Focal awareness, focal impaired awareness, and FBTCS]. Kaplan Meier and Cox analyses were performed to determine the risk, p < 0.05 was considered statistically significant. Results: Sixty patients with TRE Adult type diffuse gliomas were included (80% IDH-wt glioblastoma and 20% IDH-mut grade 4astrocytomas). The mean age was 61.5 SD ± 18.4, and 57% were male. Fifty percent of the patients presented with mesial involvement of the hemysphere. Seizure types included focal awareness (15%), focal impaired awareness (43.3%), and FBTCS (41.7%). Ninety percent of cases were treated with Levetiracetam and 33.3% presented Engel-IA postoperative seizure control. More than 90% of samples were positive for CMV-immunohistochemistry (IHC). However, all cDNA analyzed by RT-PCR return negative results. The median of overall survival (OS) was 15 months. High-grade CMV-IE infection (14 vs. 25 months, p<0.001), mesial involvement (12 vs. 18 months, p<0.001), and FBTCS were associated with worse OS (9 vs.18 months for non-FBTCS). Multivariate analysis demonstrated that high-grade CMV infection (HR = 3.689, p=0.002) and FBTCS (HR=7.007, p<0.001) were independent unfavorable survival factors. Conclusions: CMV induces a proinflammatory tumoral microenvironment that contributes to the developmet of epilepsy. Tumor progression could be associated not only with a higher degree of CMV infection but also to epileptogenesis, resulting in a seizure phenotype chracterized by FBTCS and poor survival outcomes. This study represents the first survival analysis in Latin America to include a representative sample of TRE Adult-type diffuse gliomas considering CMV-infection-degree and distinguishing features (such as FBTCS) that might have potential clinical relevance in this group of patients. Further prospective studies are required to validate these results.

ABSTRACT

PURPOSE: Coccidioidal meningitis (CM) is an uncommon disease frequently misdiagnosed. Neuroimaging and mortality are not considered in detail in previous pediatric CM series. Our objective is to evaluate outcome of pediatric neurococcidiomycosis in relation to neuroimaging findings. METHODS: We performed a prospective, observational, cross-sectional study in children with hydrocephalus and CM treated at Specialties Hospital in Torreon, Mexico (between 2015 and 2020). The outcome was evaluated by Hydrocephalus Outcome Questionnaire (HOQ) and the modified Rankin Scale (mRS). Follow-up was established at the first shunt surgery and survival since CM diagnosis confirmation. Neuroimaging was analyzed in relation to clinical data, outcome and survival. Kaplan-Meier analysis was performed with IBM-SPSS-25. RESULTS: Ten pediatric cases with CM and hydrocephalus were reported. Aged 6-228 months, 60% were female. Mean number of surgeries was 4.3 SD ± 3 (range 1-15). Asymmetric hydrocephalus was the most common neuroimaging finding (70%), followed by cerebral vasculitis (20%) and isolated fourth ventricle (IFV) (20%). The mean HOQ overall score was 0.338 SD ± 0.35. A minimum follow-up of 18 months was reported. Mean survival was 13.9 SD ± 6.15 months (range 3-24). Poor survival was correlated with asymmetric hydrocephalus (p = 0.335), cerebral vasculitis (p = 0.176), IFV (p < 0.001), bacterial superinfection (p = 0.017), lower mRS scores at hospital discharge (p = 0.017) and during follow-up (p = 0.004). The mortality rate was 20%. CONCLUSIONS: We report the largest series in Latin America of pediatric CM and hydrocephalus. Asymmetric hydrocephalus, IFV and cerebral vasculitis are complications that increase mortality and must be early diagnosed for a timely surgical and medical treatment. HOQ and mRS could be alternative scales to evaluate outcome in these patients. After a long follow-up (18 months), survival remained poor after diagnosis confirmation in our series.

ABSTRACT

Nitrates are natural compounds present in soil and water; however, the intense use of fertilizers has increased their presence in groundwater with deleterious effects on human health. There is evidence of nitrates acting as endocrine disruptors; however, the underlying molecular mechanisms have not been fully described. Here, we investigated the effect of subchronic exposure to different concentrations of sodium nitrate in female Wistar rats, evaluating thyroid hormonal parameters, such as Nis transporter (Na+ /I- symporter, Slc5a5) and Tsh-R receptor protein expression, as well as transcription of the Tpo (thyroperoxidase), Tg (tiroglobulin), Duox2 (dual oxidase 2), Pds (pendrin), and Mct8 (Mct8 transporter, Slc16a2) genes. Hematological and histochemical changes in the liver and thyroid were also explored. Significant differences were found in platelet and leukocyte counts; although a significant increase in the weight of the thyroid gland was observed, no differences were found in the levels of the hormones Tsh, T3, and T4, but a modulation of the mRNA expression of the Tg, Tpo, Duox2, Mct8, and Pds genes was observed. Morphological changes were also found in liver and thyroid tissue according to the exposure doses. In conclusion, subchronic exposure to sodium nitrate induces leukocytosis consistent with an inflammatory response and upregulation of Sod2 in the liver and increases the expression of genes involved in the synthesis of thyroid hormones, keeping thyroid hormone levels stable. Histological changes in the thyroid gland suggest a goitrogenic effect.

ABSTRACT

BACKGROUND: Coccidioidal meningitis (CM) is a fungal infectious disease that rarely affects children. Even in endemic areas, coccidiomycosis rarely affects the pediatric population. However, 40% of affected children develop hydrocephalus. Here, we describe the clinical, serological, and neuroimaging findings in a series of Mexican children admitted to our neurosurgical service with hydrocephalus and subsequently diagnosed with CM. METHODS: We report a prospective series of pediatric patients with hydrocephalus secondary to CM in an endemic area at the north of Mexico. Our report includes children with CM who were hospitalized from 2015 to 2019 in a regional hospital in Torreón, Coahuila. Clinical evolution was monitored for 1 year after hospital discharge. RESULTS: Our series include five children with CM (2-17-years-old, three female), who were hospitalized for hydrocephalus and developed intracranial hypertension. The most frequent neuroimaging findings were leptomeningeal enhancement (5/5) and basal arachnoiditis (4/5), followed by asymmetric hydrocephalus (3/5), abnormalities in fourth ventricle morphology (3/5), and cerebral vasculitis (2/5). CM was diagnosed by positive serology or pathology studies. All children were initially managed with fluconazole and a shunt was placed for management of hydrocephalus. Four patients recovered without permanent neurological deficits and one subject developed persistent vegetative state. One year after hospital discharge, none of the subjects died. CONCLUSION: This series contributes to the limited number of pediatric CM cases reported in the literature, and describes neuroimaging findings in the pediatric population. The cases here presented show that the identification of Coccidioides as causal agent in pediatric meningitis is crucial for targeted treatment and can affect dramatically neurological prognosis. Furthermore, our report stresses that even in endemic areas pediatric coccidiomycosis represents a diagnostic challenge, which is further exacerbated by the limited availability of resources in these regions. Therefore, a positive immunoglobulin G by enzyme immunoassay is enough for diagnosis of CM in endemic areas without access to CF.

ABSTRACT

OBJECTIVE: Fibromyalgia is a functional pain disorder in which patients suffer from widespread pain and poor quality of life. Fibromyalgia pain and its impact on quality of life are not effectively managed with current therapeutics. Previously, in a preclinical rat study, we demonstrated that exposure to green light-emitting diodes (GLED) for 8 hours/day for 5 days resulted in antinociception and reversal of thermal and mechanical hypersensitivity associated with models of injury-related pain. Given the safety of GLED and the ease of its use, our objective is to administer GLED as a potential therapy to patients with fibromyalgia. DESIGN: One-way crossover clinical trial. SETTING: United States. METHOD: We enrolled 21 adult patients with fibromyalgia recruited from the University of Arizona chronic pain clinic who were initially exposed to white light-emitting diodes and then were crossed over to GLED for 1 to 2 hours daily for 10 weeks. Data were collected by using paper surveys. RESULTS: When patients were exposed to GLED, but not white light-emitting diodes, they reported a significant reduction in average pain intensity on the 10-point numeric pain scale. Secondary outcomes were assessed by using the EQ-5D-5L survey, Short-Form McGill Pain Questionnaire, and Fibromyalgia Impact Questionnaire and were also significantly improved in patients exposed to GLED. GLED therapy was not associated with any measured side effects in these patients. CONCLUSION: Although the mechanism by which GLED elicits pain reduction is currently being studied, these results supporting its efficacy and safety merit a larger clinical trial.

ABSTRACT

BACKGROUND: Actinomycosis is a rare infection, frequently misdiagnosed as a neoplasia. This chronic and granulomatous disease is caused by Actinomyces israelii species. Cervicofacial actinomycosis occurs in 60% of cases and the diagnosis is commonly made by histopathology study. CASE DESCRIPTION: We report a case of fronto-orbital osteomyelitis initially misdiagnosed as a cranial bone meningioma, but later proved to be a case of actinomycosis. 99mTechnetium (99mTc) three-phase bone single-photon emission computed tomography/computed tomography (SPECT/CT) and 99mTc-ubiquicidin (UBI) 29-41 bone SPECT/CT scans were performed to corroborate the control of the infection. CONCLUSION: Craniofacial actinomycosis is the most common presentation of actinomycosis. However, it continues to be a rare and difficult disease to diagnose and is often confused with a neoplastic process. The 99mTc-UBI 29-41 bone SPECT/CT scan could be an auxiliary noninvasive diagnostic alternative and a follow-up method for these patients.

ABSTRACT

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory disorder that primarily affects women of childbearing age. There is a paucity of data on HS disease activity during menstruation, pregnancy, and menopause and the potential impact of HS on the method of delivery. OBJECTIVE: We aimed to characterize the natural history of HS symptoms during menses, pregnancy, and menopause. We also sought to evaluate the potential impact of HS on delivery method and whether there were delivery-related healing complications unique to women with HS. METHODS: An anonymous survey was distributed via social media to international HS support groups and patients at three HS specialty clinics in North America. Responses were collected from March to July 2019. RESULTS: A total of 279 respondents answered questions on disease changes during pregnancy. Menstruation caused worsening of HS symptoms in 76.7%, no change in 22.2%, and improvement in 1.1%. During pregnancy, the distribution between symptoms worsening (34.8%), having no change (28.7%), and improving (36.6%) was relatively even. After menopause, participants typically reported either worsening (39.5%) or no change (44.2%) in HS symptoms. Among respondents with anogenital HS involvement who delivered vaginally, 3.1% believed that HS interfered with vaginal delivery (VD), and 23.5% believed that VD caused an HS flare. Cesarean section (C-section) delivery was reported by 44.2% of participants. Ten participants reported that they were advised by their doctor to have a C-section instead of a VD because of severe anogenital HS. Of those who underwent a C-section, 33.9% reported that HS interfered with incision healing, and 51.2% reported developing new HS lesions in their C-section scar. CONCLUSION: To our knowledge, this is the first study describing the potential influence of HS on a patient's method of delivery. Multidisciplinary collaboration plays a pivotal role in developing individualized treatment and birth plans for pregnant women with HS.
