Epilepsy in patients with insulin-dependent diabetes and relation to glutamic acid decarboxylase 65

Objectives:To report if the association of epilepsy in pediatric patients (below the age of 15 years) with Insulin-dependent Diabetes (IDDM) at King Fahad Medical City (KFMC) is higher than the prevalence of epilepsy in the same age group (who have no IDDM) in our community. Consequently, we would determine if there is a relationship between the presence of epilepsy in diabetic children and the presence of positive antiGAD65 antibodies.Methods:This cohort study included 305 pediatric patients below the age of 15 years with Insulin-dependent Diabetes Mellitus (IDDM). They were randomly recruited at the Pediatric Endocrinology Clinic in KFMC. The patients’ caregivers were given a questionnaire between December 2015 till March 2019 to determine the seizure disorder history. There was also a retrospective review of 214 patients’ files for anti-GAD 65 positivity.Results:Our study found a significant relation between the presence of epilepsy in children with IDDM. Therefore, we could confirm the relationship between the existence of epilepsy in children with IDDM and having positive GAD65 antibodies.Conclusion:Our study supports the presence of consistent relation between having IDDM and having epilepsy in children and between the latter and the presence of positive GAD65 antibodies.

Insulin dependent diabetes Mellitus (IDDM) is a common condition in children and adolescents worldwide and so is epilepsy.1,2 Recently, there were increasing reports suggesting a potential association between having IDDM and the occurrence of epilepsy.3 Their association might represent simply a chance to relate their underlying mechanisms. However, the cause-effect relationship is not fully well defined. Literature from other countries have shown the increased prevalence of seizure disorders in this group of patients.4,5 There are scarce studies in the literature investigating IDDM characteristics contributing to having epilepsy, including positive GAD 65 antibodies. In this study that ran in King Fahad Medical City, Riyadh, Kingdom of Saudi Arabia (KSA) we are aiming to determine if the prevalence of epilepsy among 1DDM children under the age of 15 years (in our center) is higher than controls (same age without IDDM), and to check the positivity of anti-GAD 65 amongst those patients in order to find if there is a relationship between epilepsy in children with diabetes and the presence of positive GAD65 Antibodies.     

Ocular dysfunctions and toxicities induced by antiepileptic medications: Types,pathogenic mechanisms,and treatment strategies

Introduction: Ocular dysfunctions and toxicities induced by antiepileptic drugs (AEDs) are rarely reviewed and not frequently received attention by treating physicians compared to other adverse effects (e.g. endocrinologic, cognitive and metabolic). However, some are frequent and progressive even in therapeutic concentrations or result in permanent blindness. Although some adverse effects are non-specific, others are related to the specific pharmacodynamics of the drug.

Areas covered: This review was written after detailed search in PubMed, EMBASE, ISI web, SciELO, Scopus, and Cochrane Central Register databases (from 1970 to 2019). It summarized the reported ophthalmologic adverse effects of the currently available AEDs; their risks and possible pathogenic mechanisms. They include ocular motility dysfunctions, retinopathy, maculopathy, glaucoma, myopia, optic neuropathy, and impaired retinal vascular autoregulation. In general, ophthalmo-neuro- or retino-toxic adverse effects of AEDs are classified as type A (dose-dependent), type B (host-dependent or idiosyncratic) or type C which is due to the cumulative effect from long-term use.

Expert opinion: Ocular adverse effects of AEDs are rarely reviewed although some are frequent or may result in permanent blindness. Increasing knowledge of their incidence and improving understanding of their risks and pathogenic mechanisms are crucial for monitoring, prevention, and management of patients’ at risk.     

Circumstances of substance use by street youth in Egypt support the case for intervening to prevent adverse childhood experiences

Background: Egyptian street youth use substances including tobacco, illicit drugs, and pharmaceutical drugs. To understand the circumstances, including adverse childhood experiences, that place adolescents at risk for engaging in substance use, we conducted in-depth interviews among a sample of Egyptian street children. Methods: From youth residing at or attending Caritas, a non-profit organization, which provides shelter and education to street youth, seven girls and twelve boys, aged 12–18 years, participated in open-ended, in-depth interviews. Results: Eight out of the 19 participants reported family history (early exposure) to substance use; and seven of them were initiated by either a family member (sibling), friend or coworker. Most of the participants reported a history of conflict with or abuse (verbal or physical) by their parents or siblings, or stressful situations at home; they used substance(s) to alleviate their stress. Few attended school, and some were forced to work and help their family. Conclusions: Among Egyptian youth, adverse childhood experiences, such as poverty, child abuse, and family substance use, challenge somewhat susceptible youths and lead them to the path of substance use and addiction. Prevention intervention should be multifaceted, culturally adaptable, and primarily targeting the social environment during childhood.     

Age-related variations in gene expression patterns of renal cell carcinoma

Background

Clear cell renal cell carcinoma (ccRCC) is known to occur across the adult lifetime traversing the spectrum of age-related organismal changes. Little is known as to how the aging process may affect the course of renal cell carcinoma (RCC) and the repertoire of genes involved.

Diabetes mellitus. II: Routine chest radiography.

Chest radiographs of 43 consecutive diabetic patients were evaluated with a view to determine their role as a routine investigation of patients with diabetes mellitus. 22 (51.2%) patients had normal chest radiographs. The remaining 21 patients had 61 abnormalities found in their chest radiographs. 26 (42.6%) of these were significant abnormalities while 35 (57.4%) were non-significant. Of the former, 42.3% were due to cardiomegaly while in the latter group, aortic unfolding was the main finding. Radiological abnormalities were more commonly observed in patients aged 40 years and over, than in those below, with a ratio of 3:1. Chest radiographs corroborated clinical diagnosis in 19 of the 21 cases in whom abnormalities were observed. This study shows that routine chest radiograph in diabetic patients is useful in those with clinical symptoms and in older diabetics above the age of 40 years.     

Dexamethasone 8 mg in combination with ondansetron 4 mg appears to be the optimal dose for the prevention of nausea and vomiting after laparoscopic cholecystectomy

PURPOSE: The combination of antiemetic drugs could be a solution to prevent severe postoperative nausea and vomiting (PONV). The aim of this randomized double blind, dose-ranging study was to determine the minimum single effective dose of dexamethasone combined with ondansetron for the prevention of PONV in patients undergoing laparoscopic cholecystectomy. METHODS: One hundred eighty patients were allocated randomly to one of six groups to receive saline (P group), ondansetron 4 mg (O group), or ondansetron 4 mg and dexamethasone at doses of 2 mg (OD2 group), 4 mg (OD4 group), 8 mg (OD8 group), and 16 mg (OD16 group). A standardized general anesthetic was used. All episodes of PONV during the intervals of zero to six hours, 6-12 hr and 12-24 hr after surgery were evaluated using a numeric scoring system. Mean visual analogue scale pain scores at rest and on movement, the time to first demand of analgesia, total analgesic consumption in 12 hr epochs, duration of hospital stay, and side effects were recorded. RESULTS: The incidence of PONV in the OD8 (16%) and OD16 (16%) groups was lower than in the 83% (P < 0.001) and O groups (50%) at the 12-24 hr epoch (P < 0.05). There were no differences in antiemetic effect between the O, OD2 and OD4 groups and between the OD8 and OD16 groups. Pain scores, total analgesic consumption, duration of hospital stay and side effects were similar among groups. CONCLUSION: Our results suggest that 8 mg is the minimum dose of dexamethasone that, combined with ondansetron 4 mg will effectively prevent PONV in patients undergoing laparoscopic cholecystectomy.     

Vascular endothelial growth factor in psoriasis: an indicator of disease severity and control

Background  Psoriasis is a chronic disease characterized by abnormal epidermal proliferation, inflammation and angiogenesis. It has been reported that vascular endothelial growth factor (VEGF) is overexpressed in lesional psoriatic skin and its serum levels are significantly elevated in patients with moderate to severe disease.
Objective  This study aims to evaluate the possible role of VEGF in the pathogenesis of psoriasis, and its significance as an indicator of disease severity and control.
Methods  Thirty patients with moderate to severe psoriasis and 10 healthy controls were subjected to baseline evaluation of VEGF. Patients were divided into three groups according to the received treatment: psoralen plus ultraviolet A (PUVA) thrice weekly (group 1), acitretin 50 mg daily (group 2), and combined PUVA twice weekly and acitretin 25 mg daily (group 3).Treatment continued for 16 weeks or up to clinical cure. Every patient was subjected to severity evaluation by Psoriasis Area and Severity Index (PASI) and measurement of serum VEGF before and after treatment.
Results  Mean serum levels of VEGF were significantly elevated in patients (327 ± 66.2 pg/mL) than control subjects (178 ± 83.4 pg/mL). A highly significant correlation was found between VEGF and PASI score, but not with other variables. The best clinical response, the least side-effects and the highest reduction of VEGF serum levels were achieved by the combined therapy.
Conclusion  The present study supported the proposed role of VEGF in the pathogenesis of psoriasis, and suggested that it could serve as a good indicator of disease severity and control.     

Successful response of metronidazole-resistant trichomonal vaginitis to tinidazole. A case report.

Treatment of metronidazole-resistant Trichomonas vaginalis infection is complicated by the lack of an effective alternative therapeutic regimen. Data on the susceptibility of the organism to metronidazole and other nitroimidazoles are important in managing intractable cases. A case of trichomonal vaginitis with true resistance to metronidazole that responded to treatment with tinidazole is reported.

The combination of experienced operator and cytologist can yield high sensitivity and specificity, together with important prognostic information.     

Routine chest radiographs in psychiatric patients

The routine chest radiographs of 178 psychiatric patients were reviewed. 67 patients had abnormalities found on their chest radiographs. 22 (32.8 pc) of these were significant abnormalities while 45 (67.2 pc) were non-significant. There was no significant abnormality detected on the chest radiographs of any patient in whom abnormality had not been suspected clinically. No significant abnormality was found in patients below the age of 40 years. This study suggests that chest radiography should be performed only on psychiatric patients who are above the age of 40 years and especially those who have clinical evidence of chest disease.
