ABSTRACT
This study explored the average length of the incisive branch of the inferior alveolar nerve on cone-beam computed tomography (CBCT) regarding patient demographics in patients with edentulous mandibles. CBCT was utilized in a retrospective study of edentulous mandibles to assess the presence and anatomical variation for the incisive branch (IB). Three independent observers measured bilateral IB lengths. In addition to demographics, IB length and port of exit data were obtained. A one-way ANOVA was used to test IB length varied by sex or port of exit, and a standard Pearson’s correlation was used to test for IB length and age significance with a significance level of a p-value&lt;0.05. Intraclass correlation coefficients show significant agreement in IB length across all observers. No significant difference was noted between the exit port and IB length. An important effect was reported for sex, indicating women have generally shorter IB lengths (9.43 ± 3.99 vs 10.55 ± 3.92). There was a significant correlation with age, but the relationship was weak. Edentulous mandibles have an altered anatomic landscape and establishing predictive incisive branch dimensions aids practitioners in surgical planning.

Published: March 2024

ABSTRACTHead and eye turning is frequently observed during seizures. Versions with tonic and/or clonic symptoms can be differentiated from smooth head deviations. Head turning as a prominent symptom of status epilepticus has not previously been reported. We present eight case reports, (7 women/1 man, mean age 41 years, median 41.5, range 10 to 74), of status epilepticus (SE), with head turning as a prominent motor symptom. Six were accompanied by continuous frontal, occipital and temporal ictal epileptiform discharges. Furthermore, two patients had absence status with rhythmic and clonic head versions. While the localizing significance of head turnings in SE is low, in our cases, the direction was away from the discharging hemisphere in all cases of focal SE regardless of whether the turning was classified as version (three cases) or deviation (three cases). In this small series of SE, the classical observation of a patient looking away from the discharging hemisphere is still valid.

ABSTRACT
The objective of this study was to investigate bone mineral density (BMD) in Thai epileptics who had been receiving long‐term, antiepileptic drugs. Subjects were epileptic patients aged 15 to 50 years who had been taking antiepileptic drugs for longer than six months. All were free of disease and none was taking any medication that might interfere with bone metabolism other than antiepileptic drugs. BMD at the left femoral neck and spine was measured with dual energy X‐ray absorptiometry. Demographic data, basic laboratory studies and history of clinical epilepsy were obtained. One hundred and thirty patients (63 males and 67 females) were included. Mean age (+ SD) was 31.9 ± 9.7 year. There were 79 patients receiving monotherapy and 51 patients receiving polytherapy. All patients had normal serum calcium. Thirteen patients had slightly low serum phosphate levels. The BMD at the femoral neck had a mean Z‐score – 0.15 ± 1.17 and the mean Z‐score at the lumbar spine was – 0.56 ± 1.03. Thirty one patients had osteopenia at the spine and 30 patients at the femoral neck. Three patients had osteoporosis of the spine and 1 patient of the femoral neck. There was found to be no significant correlation between age, sex, body mass index, duration of treatment and type of antiepileptic drug with bone mineral density at the femur and spine. The mean BMD of long‐term antiepileptic users was lower than that of the sex and age‐adjusted mean.

ABSTRACTEEG‐triggered, blood oxygen level‐dependent functional MRI (BOLD‐fMRI) was used in 24 patients with localization‐related epilepsy and frequent interictal epileptiform discharges (spikes) to identify those brain areas involved in generating the spikes, and to study the evolution of the BOLD signal change over time. The location of the fMRI activation was compared with the scalp EEG spike focus and the structural MR abnormality. Twelve patients (50%) had an fMRI activation concordant with the EEG focus and structural brain abnormalities where present (n= 7). In 2 other patients, the fMRI activation was non‐concordant with electroclinical findings. The remaining 10 patients (41.7%) showed no significant fMRI activation. These patients had significantly lower mean spike amplitudes compared to those with positive fMRI results (p = 0.03). The time course of the BOLD response was studied in 3 patients and this revealed a maximum signal change 1.5 to 7.5 sec after the spike. In conclusion, EEG‐triggered fMRI can directly identify the generators of interictal epileptiform activity, with high spatial resolution, in selected patients with frequent spikes. The superior spatial resolution obtainable through EEG‐triggered fMRI may provide an additional non‐invasive tool in the presurgical evaluation of patients with intractable focal seizures.

ABSTRACT

Background
Video game seizures have been reported in photosensitive and non‐photosensitive patients with epilepsy. The game Super Mario World, has led to many cases of first seizures. We examined whether this game was indeed more provocative than other programs and whether playing the game added to this effect.

Methods
We prospectively investigated 352 patients in four European cities, using a standard protocol including testing of a variety of visual stimuli. We correlated historical data on provocative factors in daily life with electroencephalographic laboratory findings.

Results

The video game, Super Mario World proved more epileptogenic than standard TV programs and as provocative as programs with flashing lights and patterns. Most striking was the fact that video game‐viewing and‐playing on the 50 and 100 Hz TV was significantly more provocative than viewing the standard program (
P
< 0.001,
P
< 0.05 respectively).

Playing the video game Mario World on a 50 Hz TV, appeared to be significantly more provocative than playing this game on the 100 Hz TV (
P
< 0.001). Of 163 patients with a history of TV‐, VG‐ or CG‐seizures, 85% of them showed epileptiform discharges in response to photic stimulation, 44% to patterns, 59% to 50 Hz TV and 29% to 100 Hz TV.

Conclusions
Children and adolescents with a history of video game seizures are, in the vast majority, photosensitive and should be investigated with standardised photic stimulation. Games and programs with bright background or flashing images are specifically provocative. Playing a video game on a 100 Hz TV is less provocative [published with videosequences].
Knowledge of epilepsy and attitudes towards the condition among schoolteachers in Bobo‐Dioulasso (Burkina Faso)

Published: March 2024

ABSTRACT
Epilepsy is one of the stigmatising afflictions still common in Africa. The attitudes toward people with epilepsy are influenced by the degree of knowledge of the condition. This study was conducted to assess 260 teachers' knowledge and attitude towards epilepsy. They answered a semi‐structured questionnaire in order to quantify their knowledge of and attitude towards epilepsy in Bobo‐Dioulasso. Teachers were chosen at random. Almost all the teachers had heard about epilepsy, with 43.2% of them linking epilepsy to a central nervous system disturbance. Some teachers still thought that epilepsy was contagious or hereditary, and 15.4% objected to having epileptic children in their classes. Their knowledge of the clinical characteristics and first aid for a person during a seizure was unsatisfactory, and 56.5% of teachers who believed that epilepsy could be cured, thought that this disease should be treated by both modern and traditional medicines. The majority of teachers were interested in training involving clinical manifestations, aetiology of epilepsy and first aid procedures. Schools should offer some kind of information and assistance in health matters, and physicians should ensure that teachers have sufficient knowledge of epilepsy. More knowledge among primary school teachers should avoid discrimination against pupils with epilepsy.
Hypocalcemic generalised seizures as a manifestation of iatrogenic hypoparathyroidism months to years after thyroid surgery
Authors: Mrowka Matthias , Knake Susanne , Klinge Harald , Odin Per , Rosenow Felix 
Published: March 2024

ABSTRACT
Hypoparathyroidism is a relatively common side effect of a thyroidectomy and leads to hypocalcemia. Carpopedal spasm and tetany are typical manifestations and usually occur within weeks after surgery. The first signs can be less typical and include movement disorders such as chorea, as well as symptoms of increased intracranial pressure or epileptic seizures. We describe two cases with generalised tonic‐clonic seizures as the first manifestation of postoperative hypoparathyroidism, appearing months and years after thyroidectomy. Iatrogenic hypoparathyroidism needs to be considered in the differential diagnosis of adult‐onset, generalised, tonic‐clonic seizures even if the thyroidectomy was performed years earlier.

ABSTRACT
Benign childhood epilepsy with centrotemporal spikes (BECTS) is regarded as a benign form of epilepsy because of its usually favorable outcome, in terms of seizures. Eighteen children with BECTS were studied in terms of neuropsychological and learning abilities: intellectual quotient, oral language (phonological production, naming skills, verbal fluency and syntactic comprehension), drawing and visuo‐spatial skills, visual and selective attention, verbal and visuo‐spatial memory, reading, numeracy and spelling. The mean IQ of the population was within the normal range, but individual results were heterogeneous. Verbal functions and memory were normal. In contrast, drawing and visuo‐spatial skills, attention and visuo‐spatial memory were significantly weak compared to the normal range for age. Reading, numeracy and/or spelling ability were significantly delayed by one academic year or more in ten of the children. In conclusion, despite its benign outcome in terms of epilepsy, BECTS can be accompanied by specific cognitive disorders and low academic achievement.
The Bancaud and Talairach view on the epileptogenic zone: a working hypothesis
Authors: Kahane Philippe , Landré Elisabeth , Minotti Lorella , Francione Stafano , Ryvlin Philippe 
Published: March 2024

ABSTRACT
The definition of the epileptogenic zone, as proposed by Talairach and Bancaud, is an ictal electro‐clinical definition based on the results of stereotactic intracerebral EEG (SEEG) recordings. It takes into account not only the anatomical location of the “site of the beginning and of the primary organization” of the epileptic discharge, but also how this discharge gives rise to the accompanying clinical symptoms. This definition is different from the North American view since, for the french authors, the epileptogenic zone is not synonymous with what can be called the “what‐to‐remove area”. In fact, it is above all a conceptual definition which emphazises the importance of studying the spatio‐temporal dynamics of seizure discharges, and not only their starting point.

Published: March 2024

ABSTRACTPatients with Taylor‐type focal cortical dysplasia (TTFCD) generally present with medically intractable epilepsy and impaired neurological and/or intellectual functioning. Surgery usually proves to be the only treatment approach leading to control of seizures. We describe a 17‐year‐old girl with TTFCD who exhibited a very long period of seizure remission. Combined clinical and neuroimaging findings were compatible with a diagnosis of a balloon cell‐subtype TTFCD. As for the clinical course, partial motor seizures began at one year of age and ceased at five: our patient has had no seizure recurrence over a 12‐year‐follow‐up. Moreover, throughout the 15‐year follow‐up, neurological examinations and cognitive abilities always remained within normal limits. Neuropsychological assessment clearly showed no impairments in executive functions: planning abilities, working memory, attention and impulse control, or constructive aspects of motor coordination. The predominant deficits pertained to verbal abilities in the context of borderline intellectual performances. To our knowledge, this case report documents the longest duration of seizure remission in a patient with TTFCD, thus emphasizing the possible benign course of such dysplastic lesions which usually have a poor prognosis, leading to early surgical treatment.
Ciri Geokimia Batuan Vulkaniklastika di daerah Tanjung Balit, Sumatra Barat: Suatu Indikasi Kegiatan Magma pada Eosen
Authors: Harahap Bhakti H. 
Published: March 2024

DOI: 10.17014/ijog.v5i2.94Volcaniclastic rocks exposed in the Tanjung Balit area, West Sumatra, are red in color, loose, soft, and fractured. The rocks are strongly altered to be clay with calcium (CaO) and natrium (Na2O) contents extremely low (0.02 and maximum 0.30wt% respectively), and high loss of ignition (LOI) (4-15wt%). Mobile minor elements such as strontium (Sr), rubidium (Rb), and lanthanum (La) are also changed as their values do not fit to a normal contents range of fresh volcanic rocks in general. Geochemical analyses of the rocks resulted in the following oxide values: silica (SiO2) ranges from 58 – 68wt%, alumina (Al2O3) 15,90 – 21,46wt%, magnesium (MgO) 1, 36 – 1.61wt%, iron oxides (Fe2O3) 4,8-6,9wt%, potassium (K2O) 2,73 - 4,23wt% and titanium (TiO2) 0,60 - 0,70wt%. In general, the element contents especially the immobile ones (Ti, Mg and Fe) show that the rocks were originated from magmatic activity, which is also supported by petrographical characteristics that are still showing felspar and quartz minerals relicts. Based on SiO2 versus K2O diagram, these rocks are classified as high K-calc-alkaline series and belong to an intermediate composition. The rocks of the above criteria such as high alumina, very low magnesium and less than 1% titanium are one of the evidences that they are a magmatic arc product. The trace element of the rocks is summarized on the spider diagram; here their patterns strongly resemble to the typical of magmatic arc as well with enrichment in large ion lithophile elements (LILE) and light rare earth elements (LREE) relative to high field strength elements (HFSE) and heavy REE (HREE). Trace element pattern and REE suggest they were originated from a high K- calc-alkaline magma source.

Published: March 2024

DOI: 10.17014/ijog.v5i4.105In order to gain insights into the detailed physical disintegration characteristics of various types of mudrock, a series of static slaking exposure and immersion tests were carefully carried out in this study. The intent of this paper is to exhaustively describe and discuss the results of the tests, including slaking mechanism, mode and rate/intensity. In general, it can be obviously identified that there are significant different susceptibilities of each mudrock tested to slake-disintegration. These differences can not only be identified from the results of slaking exposure test but also from slaking immersion test. It seems that there is also an agreement in both testing results, which show that the most resistant mudrock to slaking was Ikeshima shales, and was comparatively, followed by Ombilin siltstones, Tanjung Enim mudstones-claystones, and Subang claystones as the worst slaking characteristic. The detailed differences in fundamental characteristics of physical disintegration characteristics will further widely be discussed in this paper.
Metamorphic Rock-Hosted Orogenic Gold Deposit Type as a Source of Langkowala Placer Gold, Bombana, Southeast Sulawesi

Published: March 2024

DOI: 10.17014/ijog.v6i1.114In 2008, placer gold was discovered in Langkowala area (Bombana Regency), Southeast Sulawesi, Indonesia, and more than 60,000 traditional gold miners in the early 2009 have been operating by digging vertical pits and panning active stream sediments. The grade of placer gold ranges from 50 to 140 g/t. Local geological framework indicates that the placer gold is not related to volcanic rock-related hydrothermal gold deposit, e.g. epithermal, skarn or porphyry. This paper describes a preliminary study on possible primary deposit type as a source of the Langkowala (Bombana) secondary placer gold. A field study indicates that the Langkowala (Bombana) placer/paleoplacer gold is possibly related to gold-bearing quartz veins/veinlets hosted by metamorphic rocks particularly mica schist and metasediments in the area. These quartz veins/veinlets are currently recognized in metamorphic rocks at Wumbubangka Mountains, a northern flank of Rumbia Mountain Range. Sheared, segmented quartz veins/veinlets are of 2 cm to 2 m in width and contain gold in a grade varying between 2 and 61 g/t. At least, there are two generations of the quartz veins. The first generation of quartz vein is parallel to foliation of mica schist and metasediments with general orientation of N 300oE/60o; the second quartz vein generation crosscut the first quartz vein and the foliation of the wallrock. The first quartz veins are mostly sheared/deformed, brecciated, and occasionally sigmoidal, whereas the second quartz veins are relatively massive. The similar quartz veins/veinlets types are also probably present in Mendoke Mountain Range, in the northern side of Langkowala area. This primary gold deposit is called as ‘orogenic gold type’. The orogenic gold deposit could be a new target of gold exploration in Indonesia in the future.
The Characteristics of Lahar in Merapi Volcano, Central Java as the Indicator of the Explosivity during Holocene

Published: March 2024

DOI: 10.17014/ijog.v6i2.116Merapi Volcano in Central Java has been the most active volcano during Holocene time. As a strato volcano, Merapi exhibits alternating volcanic activities of effusive and explosive characters and self destruction. The explosivity index has evolved during the last ten thousand years. The effusive activities were characterized by the occurrence of lava flows, the development of lava dome, and the production of the “nuee ardente d’avalanche” called Merapi type. The explosive stage is frequently accompanied by the occurence of pyroclastic flows. The present investigation is attempted to reveal the relationship between the characteristics of lahar and the evolution of the activity of Merapi Volcano. The quantitative analysis was focused on the size and shape of the lahar components particularly that of pumice as the main indicators in 73 measured stratigraphic columns of lahar deposits. In addition, the main chemical element rim structures of hornblende identified in lahar components indicate the different lahar units. There are five lahar units and five groups of Merapi activities which can be distinguished. It can be concluded that the characteristics of lahar reflect the evolution of the activities in the past. The risk analyses of Merapi Volcano therefore can be enlarged to cover the possible hazard based on the lahar characteristics.
Geochemical Evidence of Island-Arc Origin for Sumatra Island; A New Perspective based on Volcanic Rocks in Lampung Province, Indonesia
Authors: Zulkarnain Iskandar 
Published: March 2024

DOI: 10.17014/ijog.v6i4.128Since decades, Sumatra Island is considered as the Eurasia continental margin where the Indian Ocean plate has been subducted oblique beneath the continental plate of Sumatra. But, the occurrences of volcanic rocks in almost all areas of Lampung Province in the southernmost of Sumatra Island, as the presence of the Quaternary Tanggamus Volcano in the western part of the province together with the Quaternary Rajabasa Volcano in the eastern area cannot be justified using the consideration. Spider diagrams of trace and rare earth elements of volcanic rocks from the western and eastern areas of the province reveal that the rocks come from three different tectonic settings, namely island-arc, active continental margin (ACM), and intra continental plate. All basalt and one dacite of western volcanic rocks show a character of island-arc origin, while the eastern volcanic rocks are reflecting characters of ACM and intra continental plate. Plot of the rocks in the diagram of Ta/Yb versus Ce/P and in Ta/Yb versus Th/Yb confirmed the tectonic environments and specifically classify the intra continental plate into Within Plate Volcanic Zone (WPVZ). The island-arc group is characterized by Ta/Yb ratio of less than 2.0 and Ce/P less than 1.8. The ACM group is recognized having Ta/Yb ratio between 2 and 4 with Ce/P more 1.8, while the WPVZ group is defined as a group having Ta/Yb more than 6 and Ce/P more than 1.0. The result indicates that the western part of Sumatra is an island-arc fragment and the eastern part belongs to the Eurasia continental margin. The concentration of volcanics having ACM character from areas around the Sumatra Fault System to the east indicates that the collision zone between the Sumatra island-arc fragments with the Eurasia continental margin is probably located along the SFS. More statistical data is still needed from other Sumatra volcanics to confirm this conclusion.
