Association between Clinical Features and Magnetic Resonance Imaging Findings in Patients with Temporal Lobe Epilepsy

Background: Temporal lobe epilepsy (TLE) is the most common cause of partial seizures. However, there is a paucity of data on the correlation of clinical and semiological features of TLE with specific imaging findings on magnetic resonance imaging (MRI). Objective: In this study, we sought to evaluate the association between the semiology of TLE with specific etiological findings as identified on MRI. Materials and methods: This was a single-center, observational study in which consecutive patients presenting with clinical features diagnostic of TLE underwent a brain MRI on a 1.5 T scanner. The data collected from the various MR parameters were then correlated with history. Results: A total of 90 patients were included in the study. The mean age of the study population was 29.1 years. Females comprised 45% of the study population. Mesial temporal sclerosis (MTS) was the most common imaging finding in about 60% of patients. Four out of five patients had aura whereas 70% had automatisms. The presence of aura in TLE patients was significantly associated with MTS on MRI (p = 0.042). The presence of automatism and history of childhood febrile seizure did not have a significant association with any specific etiological findings on MRI (p = 0.254 and 0.731, respectively). Drug-refractory epilepsy was commonly associated with the presence of MTS on MRI (p = 0.004). The presence of dual pathology on MRI was associated with drug-refractory epilepsy (p = 0.031). Conclusions: The presence of aura and drug-refractory epilepsy point towards the presence of MTS. Dual pathology, on MRI, in TLE patients may be a risk factor for drug-refractory epilepsy.

Retrospective study of chikungunya outbreak in urban areas of India.

Background & objectives: A retrospective study on chikungunya outbreak in India in five States viz. Delhi, Madhya Pradesh, Orissa, Maharashtra and Kerala was conducted in 2007-2008 to know the distribution and determinants of chikungunya fever outbreak in India. Methods: On the basis of high and low incidence of chikungunya fever, two districts from each State and two wards from the selected district were taken for random selection of 1000 households from 10 districts and 5 States. Semi-structured questionnaires were administered to individuals, patients, qualified health professionals and to stakeholders for collecting information. Results: The educational background and occupation of the respondents showed variations across the study States. Only in high incidence ward of Maharashtra, water storage period for 3-6 days and emptying, drying of water containers on weekly basis was noted. The study through knowledge, attitude, belief, practice (KABP) obtained individual's perception of chikungunya fever, its prevention and control. Patients’ expenditure on treatment was mainly recorded less than Rs 500 across study States. Health facility survey obtained an overview of the capacity of local health facilities. Stakeholders’ perception regarding chikungunya fever was also noted. Interpretation & Conclusions: The study revealed differences in awareness of chikungunya, cause of the disease, vector responsible, mode of transmission, biting time and elimination of breeding of mosquitoes statistically significant among high and low incidence wards of all the States. Expenditure on treatment was independent of economically active status and loss of man-days across all the States. Education and occupation did not have any relation with emptying/drying of water containers in high incidence wards. Strengthening of surveillance, information, education and communication (IEC) activities along with case management facilities may be provided by the State health department for prevention of chikungunya outbreaks in future. Stakeholders should be more involved in outbreak management and future planning.

An unusual presentation of pulmonary echinococcosis.

A case of pulmonary hydatid disease presenting with right supraclavicular cystic swelling is being reported. Radiologically, the cyst had an extension into the chest wall with bony involvement in the form of destruction and thinning of the first and second ribs on the right side. The patient responded to albendazole therapy.
