Lennox–Gastaut syndrome in south Iran: Electro-clinical manifestations

PurposeLennox–Gastaut syndrome (LGS) is an uncommon epileptic encephalopathy. In this study, we tried to determine the clinical and EEG characteristics of patients with LGS in south Iran.MethodsIn this retrospective study, all patients with a clinical diagnosis of LGS were recruited at the outpatient epilepsy clinic at Shiraz University of Medical Sciences from 2008 through 2012. Age, gender, age at seizure onset, seizure type(s), epilepsy risk factors, EEG and imaging findings of all patients were registered routinely.ResultsDuring the study period, 2500 patients with epilepsy were registered at our epilepsy clinic. One-hundred and thirty-five patients (5.4%) were diagnosed as having LGS. Age of onset (mean ± standard deviation) was 3.2 ± 3.8 years. In 14 (10.4%) patients, age of onset was above 8 years. Eighty-three patients (61.5%) were male and 52 (38.5%) were female. The most common seizure type was tonic, followed by generalized tonic–clonic and myoclonic seizures. The most common EEG finding was slow spike-wave complexes. The most common abnormal MRI finding was brain atrophy.ConclusionLGS is an uncommon epileptic encephalopathy characterized by multiple seizure types, a specific electroencephalographic pattern and psychomotor retardation, beginning in childhood. However, variants of this classical triad including atypical EEG findings, normal psychomotor function, and late-onset disease could be seen in some patients. These atypical findings in a patient with typical history for LGS should not deter from the correct diagnosis. The mainstay for making a correct syndromic diagnosis is a detailed clinical history.     

Intestinal parasitic infection: prevalence,knowledge, attitude,and practices among schoolchildren in an urban area of Taiz city,Yemen

BackgroundIntestinal parasitic infections (IPIs) are regarded as one of the main public health problems and socio-economic issues adversely affecting the health of millions of people worldwide. Our study aimed to describe the knowledge, attitude, and practices of local urban schoolchildren in Taiz City towards intestinal parasitic infections.Methods and materialThis is a cross-sectional study conducted in Taiz, Yemen from March to May 2019. A total of 385 schoolchildren were selected using a random sampling technique from 7 primary schools. Wet-mount microscopic examination, formol-ether concentration techniques, and Lugols'' iodine were employed in parasite detection and cyst identification.ResultsOf the 385 schoolchildren examined for IPIs, 107 (27.8%) were positive for the presence of enteric parasites, some having multiple infections. The prevalence was slightly higher in males 46 (28.6%) than in females 61 (27.2%) but have no statistical difference (P = 0.77). Entamoeba histolytica/dispar was the most common infection with 16.4% of cases. A substantial percentage (40.5%) of the respondents displayed poor knowledge. The respondents also revealed inappropriate attitudes and practices that contribute to the prevalence of IPIs in the study.ConclusionsThe study revealed the prevalence of intestinal parasites among the schoolchildren in Taiz, Yemen, suggesting that IPIs remain a major public health problem. Entamoeba histolytica/dispar was the most prevalent intestinal parasites identified among the schoolchildren. Age, poor knowledge of the mode of transmission, prevention, and acquisition of IPIs, and poor habitual hygiene practices increase the risk of acquiring intestinal infections.     

Active surveillance is superior to radical nephrectomy and equivalent to partial nephrectomy for preserving renal function in patients with small renal masses: Results from the DISSRM registry

Purpose

We compared renal function outcomes among patients in the surveillance and intervention arms of the DISSRM registry.

Dashboard (in the) Knee

We present the case of a 19-year-old individual presenting to an orthopaedic outpatient clinic several months following a dashboard knee injury during a road traffic accident with intermittent mechanical symptoms. Despite unremarkable examination findings and normal magnetic resonance imaging, the patient was identified subsequently as having an intra-articular plastic foreign body consistent with a piece of dashboard on arthroscopic knee assessment, the retrieval of which resulted in a complete resolution of symptoms.     

Pulp revascularization for immature replanted teeth: a case report

Immature avulsed teeth are not usually treated with pulp revascularization because of the possibility of complications. However, this therapy has shown success in the treatment of immature teeth with periapical lesions. This report describes the case of an immature replanted tooth that was successfully treated by pulp revascularization. An 8‐year‐old boy suffered avulsion on his maxillary left lateral incisor. The tooth showed incomplete root development and was replanted after 30 minutes. After diagnosis, revascularization therapy was performed by irrigating the root canal and applying a calcium hydroxide paste and 2% chlorhexidine gel for 21 days. In the second session, the intracanal dressing was removed and a blood clot was stimulated up to the cervical third of the root canal. Mineral trioxide aggregate was placed as a cervical barrier at the entrance of the root canal and the crown was restored. During the follow‐up period, periapical repair, apical closure and calcification in the apical 4 mm of the root canal was observed. An avulsed immature tooth replanted after a brief extra‐alveolar period and maintained in a viable storage medium may be treated with revascularization.
