    Fasting can influence psychological and mental states. In the current study, the effect of periodical fasting on the process of emotion through gazed facial expression as a realistic multisource of social information was investigated for the first time. The dynamic cue-target task was applied via behavior and event-related potential measurements for 40 participants to reveal the temporal and spatial brain activities - before, during, and after fasting periods. The significance of fasting included several effects. The amplitude of the N1 component decreased over the centroparietal scalp during fasting. Furthermore, the reaction time during the fasting period decreased. The self-measurement of deficit arousal as well as the mood increased during the fasting period. There was a significant contralateral alteration of P1 over occipital area for the happy facial expression stimuli. The significant effect of gazed expression and its interaction with the emotional stimuli was indicated by the amplitude of N1. Furthermore, the findings of the study approved the validity effect as a congruency between gaze and target position, as indicated by the increment of P3 amplitude over centroparietal area as well as slower reaction time from behavioral response data during incongruency or invalid condition between gaze and target position compared with those during valid condition. Results of this study proved that attention to facial expression stimuli as a kind of communicative social signal was affected by fasting. Also, fasting improved the mood of practitioners. Moreover, findings from the behavioral and event-related potential data analyses indicated that the neural dynamics of facial emotion are processed faster than that of gazing, as the participants tended to react faster and prefer to relay on the type of facial emotions than to gaze direction while doing the task. Because of happy facial expression stimuli, right hemisphere activation was more than that of the left hemisphere. It indicated the consistency of the emotional lateralization concept rather than the valence concept of emotional processing.

    Differentiating between anaphylaxis and hypotension during general anaesthesia is difficult, especially when patients present with only hypotension and without any of the other classical features of anaphylaxis. We report the successful management of an anaphylactic reaction to rocuronium that presented as isolated hypotension in a 45-year-old Indonesian man presented with lacerations on the scalp and right pinna caused by an assault to the head after the induction of general anaesthesia, refractory to fluids and high doses of vasopressors. This case highlights that a possible indicator of anaphylaxis can be the presence of isolated hypotension during.

    Awake craniotomy is a brain surgery in patients who are kept awake when it is indicated for certain intracranial pathologies. The anaesthetic management strategy is very important to achieve the goals of the surgery. We describe a series of our first four cases performed under a combination of scalp block and conscious sedation. Scalp block was performed using a mixture of ropivacaine 0.7% and adrenaline 5 5µg/ ml administered to the nerves that innervate the scalp. Conscious sedation was achieved with a combination of two recently available drugs in our country, dexmedetomidine (selective α 2-agonist) and remifentanil (ultra-short acting opioid). Remifentanil was delivered in a target controlled infusion (TCI) mode.

    Epidermoid cyst is a common benign cutaneous swelling frequently encountered in surgical practice. It usually presents as a painless lump frequently occurring in hairbearing areas of the body particularly the scalp, scrotum, neck, shoulder and back. Giant epidermoid cysts commonly occur in hairy areas such as the scalp. We present here the case of a rare occurrence of a giant epidermoid cyst in the less hairy area of the right upper thigh mimicking a soft tissue sarcoma. Steps are highlighted for the management of this unusual cyst.

    We report a case of a 13-year-old boy who presented with acute onset of generalised erythematous skin and patchy areas of pustules for one week duration. He was well until one month ago when he started having small scaly plaques on his scalp and extensors of his legs. During the acute episode, he also had joint pain and bilateral conjunctivitis. Skin biopsy confirmed pustular psoriasis. He developed leucocytosis and transaminitis during the acute phase of the pustular eruption while on acitretin, which was then withheld. Subsequently, treatment with oral cyclosporine induced remission of his skin and joint disease. The case is hereby reported because of rarity of presentation and clinical features. Oral cyclosporine should be considered in patients with generalised pustular psoriasis complicated with transaminitis.

    Kerion is an inflammatory type of tinea capitis which can be mistaken for bacterial infection or folliculitis as both conditions display similar clinical features. It occurs most frequently in prepubescent children and rarely in adults. We report a 26-year-old woman who presented with multiple tender inflammed nodules on her scalp. Her condition was misdiagnosed as bacterial abscess and treated with multiple courses of antibiotics without improvement. Later, her condition was re-diagnosed as kerion based on clinical appearance, history of contact with infected animal and Wood's lamp examination. symptoms and lesions resolved completely with systemic antifungal treatment leaving residual scarring alopecia. The delay in the diagnosis and treatment of this patient resulted in permanent scarring alopecia.

    INTRODUCTION: Craniotomy tumour is brain surgery that can induce a stress response. The stress response can be measured using haemodynamic parameters and plasma cortisol concentration. The stress response that occurs can affect an increase in sympathetic response, such as blood pressure and heart rate, which can lead to an increase in intracranial pressure. Scalp block can reduce the stress response to surgery and post-operative craniotomy tumour pain. The local anaesthetic drug bupivacaine 0.25% is effective in reducing post-operative pain and stress in the form of reducing plasma cortisol levels. The adjuvant addition of clonidine 2 μg/kg or dexamethasone may be beneficial.

    MATERIALS AND METHODS: A randomised control clinical trial was conducted at the Central Surgery Installation and Hasan Sadikin General Hospital Bandung and Dr. Mohammad Husein Hospital Palembang from December 2022 to June 2023. A total of 40 participants were divided into two groups using block randomisation. Group I receives bupivacaine 0.25% and clonidine 2 μg/kg, and group II receives bupivacaine 0.25% and dexamethasone 8 mg. The plasma cortisol levels of the patient will be assessed at (T0, T1 and T2). All the patient were intubated under general anesthaesia and received the drug for scalp block based on the group being randomised. Haemodynamic monitoring was carried out.

    RESULTS: There was a significant difference in administering bupivacaine 0.25% and clonidine 2μg/kg compared to administering bupivacaine 0.25% and dexamethasone 8 mg/kg as analgesia for scalp block in tumour craniotomy patients on cortisol levels at 12 hours post-operatively (T1) (p=0.048) and 24 hours post-surgery (T2) (p=0.027), while post-intubation cortisol levels (T0) found no significant difference (p=0.756). There is a significant difference in Numeric Rating Scale (NRS) at post-intubation (T0) (p=0.003), 12 hours post-operatively (T1) (p=0.002) and 24 hours post-surgery (T2) (p=0.004), There were no postprocedure scalp block side effects in both groups.

    CONCLUSION: The study found that scalp block with 0.25% bupivacaine and 2μg/kg clonidine is more effective in reducing NRS scores and cortisol levels compared bupivacaine 0.25% and dexamethasone 8mg in tumour craniotomy patients.

    INTRODUCTION: Pediculosis capitis infestation is endemic in both developing and developed countries leading to various physical, economical and psychological consequences. Our main objective was to determine the prevalence and predictors of pediculosis capitis among primary school children in Hulu Langat District, Malaysia.

    METHODS: An analytic cross-sectional study using cluster random sampling method was carried out in Hulu Langat District, Malaysia. Self-administered pretested questionnaires were used to collect the data. Hair and scalp examination was also carried out. Multivariate logistic regression was used to control for potential confounding and determine the predictors.

    RESULTS: The overall mean age of the 1,336 respondents was 9.3 years. Majority were males (52.8%), Malays (79.5%) and 81.3% of the fathers had secondary or tertiary education as compared to 77.3% for the mothers. The overall prevalence of pediculosis capitis was 15.3%. The prevalence of pediculosis was significantly higher among females (28.4%) than males (3.7%, p=0.001). Multivariate logistic regression analysis showed that age 10 years or more (Odds Ratio (OR) = 2.34, 95% Confidence Interval (CI) = 1.673 to 3.272), female gender (OR = 10.26, 95% CI = 6.620 to 15.903), history of contact with an infested person (OR = 2.11, 95% CI = 1.506 to 2.960), Indian compared to Chinese (OR = 3.55, 95% CI = 1.282 to 9.860), Malay to Chinese (OR = 2.59, 95% CI = .994 to 6.774) were associated with pediculosis capitis.

    CONCLUSIONS: Prevalence of pediculosis capitis among children aged 7 - 12 years in Hulu Langat District was high. There is a need for screening and treatment of pediculosis capitis in primary schools.

    Angiosarcoma is one of the rarest types of malignant vascular tumours that involved the head and neck region. It predominantly affects the scalp and superficial soft tissues. Angiosarcoma arising from the deep cervical soft tissue is extremely rare. There is a limited literature on neck angiosarcoma that occurred simultaneously with papillary thyroid carcinoma. We report a rare case of concurrent papillary thyroid carcinoma and cervical epithelioid angiosarcoma, and postoperative rapid progression of residual angiosarcoma that mimicked a neck haematoma. The diagnostic challenge and possible etiologies have been discussed here.

    Hidradenitis suppurativa (HS) is known to have association with systemic diseases with chronic inflammation such as psoriasis. We aim to describe the concomitant systemic inflammation in patients with HS using 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET/CT) scan. This was a case-control study conducted in three tertiary hospitals in Northern Malaysia from January to December 2017, involving HS patients aged 18 years and above. Thirty-two HS patients with age- and sex-matched controls were recruited with a mean age of 31.4 years (range: 18-56). Numerous cutaneous inflammatory foci were detected on FDG-PET/CT scan in clinically unapparent sites (27/32, 84.4%). Approximately 90.6%, 93.8%, and 50.0% of the patients had significantly higher cutaneous uptake over nasal, mandibular, and scalp regions, respectively (P < 0.0001). PET/CT scan did not detect any systemic inflammation unlike those found in psoriasis. Three (9.4%) patients had thyroid nodules with high uptake (maximum standard uptake values ranging from 2.9 to 11.3). Two of them were confirmed to have papillary thyroid carcinoma, while the third patient has inconclusive finding. 18F-FDG PET/CT scan may be useful to map disease burden of HS. Nonlesional inflammatory foci on the skin of the nose, mandibular, and scalp are probably significant. The association of thyroid carcinoma in HS warrants further evaluation.

    A young man presented to our centre needing an urgent debridement of his postcraniotomy wound due to massive myiasis during the COVID-19 pandemic in October 2020. Prior to the surgery, his nasopharyngeal swab real-time PCR test result was unknown. One day later, it returned as SARS-CoV-2 positive. All healthcare workers who were involved in the patient management avoided cross infection as they wore appropriate personal protective equipment. This article depicts the importance of adequate preparations when handling potentially infectious patients and the perioperative issues associated with it.

    Langerhans Cell Histiocytosis (LCH) is an uncommon neoplastic disorder characterized by accumulation of histiocytes in various tissues. The clinical manifestation is highly variable, ranging from an isolated skin rash or a single bony lesion, to fatal multi-organ failure. Due to its rarity and systemic involvement, the epidemiology of LCH is still not fully understood and most studies focus on the paediatric population. The extent of clinical involvement has important prognostic implications. Treatment options may be local or systemic depending on disease extent. Here we describe a rare case of adult onset LCH who presented with recurrent pneumothoraces, diabetes insipidus and papules and plaques over the scalp and forehead.

    Dermatofibrosarcoma protuberans (DFSP) is a slowgrowing, locally invasive tumour of the dermis. It commonly presents in the trunks and proximal extremities but is seen to a lesser extent in the head and neck regions. We present a case report of a recurrent DFSP in a 48-year-old Iban woman at the occipital region. The patient underwent wide local excision and removal of outer table of cranium, dressing followed by split thickness skin graft. Histopathological examination confirmed dermatofibrosarcoma protuberans with clear lateral surgical margins and a deep margin of 0.5mm. She is currently undergoing radiotherapy and is planned for 50Grey 25cycles.

    PURPOSE: We investigated the effects of humidity on regional sweating secretion and active sweat gland density on the scalp during passive heating in hot environments.

    METHODS: Eight male subjects shaved their heads prior to expose to dry (30%RH; H30%) and humid (85%RH; H85%) conditions at an air temperature of 32 °C. Total sweat rate, local sweat rates (frontal, vertex, temporal, and occipital regions), active sweat glands on the scalp (2 frontal, 2 parietal, 2 temporal, 1 occipital, and 1 vertex), and rectal and skin temperatures were measured during leg immersion in 42 °C water for 60 min.

    RESULTS: (1) Total sweat rates were greater for H30% (179.4 ± 35.6 g h-1) than for H85% (148.1 ± 27.2 g h-1) (P Scalp sweat secretion tended to be greater in the H85% than the H30%. (3) Head sweat rates were greater on the frontal than on the vertex for both humidity conditions (P scalp was greater for H85% (82 ± 13 glands cm-2) than for H30% (62 ± 17 glands cm-2) (P scalp region were significantly increased in the hot-humid condition compared to the hot-dry condition. Among the regions on the scalp surface, the vertex was the least sensitive to the change in humidity.

    This study analyzes the learning styles of subjects based on their electroencephalo-graphy (EEG) signals. The goal is to identify how the EEG features of a visual learner differ from those of a non-visual learner. The idea is to measure the students' EEGs during the resting states (eyes open and eyes closed conditions) and when performing learning tasks. For this purpose, 34 healthy subjects are recruited. The subjects have no background knowledge of the animated learning content. The subjects are shown the animated learning content in a video format. The experiment consists of two sessions and each session comprises two parts: (1) Learning task: the subjects are shown the animated learning content for an 8-10 min duration. (2) Memory retrieval task The EEG signals are measured during the leaning task and memory retrieval task in two sessions. The retention time for the first session was 30 min, and 2 months for the second session. The analysis is performed for the EEG measured during the memory retrieval tasks. The study characterizes and differentiates the visual learners from the non-visual learners considering the extracted EEG features, such as the power spectral density (PSD), power spectral entropy (PSE), and discrete wavelet transform (DWT). The PSD and DWT features are analyzed. The EEG PSD and DWT features are computed for the recorded EEG in the alpha and gamma frequency bands over 128 scalp sites. The alpha and gamma frequency band for frontal, occipital, and parietal regions are analyzed as these regions are activated during learning. The extracted PSD and DWT features are then reduced to 8 and 15 optimum features using principal component analysis (PCA). The optimum features are then used as an input to the k-nearest neighbor (k-NN) classifier using the Mahalanobis distance metric, with 10-fold cross validation and support vector machine (SVM) classifier using linear kernel, with 10-fold cross validation. The classification results showed 97% and 94% accuracies rate for the first session and 96% and 93% accuracies for the second session in the alpha and gamma bands for the visual learners and non-visual learners, respectively, for k-NN classifier for PSD features and 68% and 100% accuracies rate for first session and 100% accuracies rate for second session for DWT features using k-NN classifier for the second session in the alpha and gamma band. For PSD features 97% and 96% accuracies rate for the first session, 100% and 95% accuracies rate for second session using SVM classifier and 79% and 82% accuracy for first session and 56% and 74% accuracy for second session for DWT features using SVM classifier. The results showed that the PSDs in the alpha and gamma bands represent distinct and stable EEG signatures for visual learners and non-visual learners during the retrieval of the learned contents.
