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.

PMID: 20949243

For the management of a full-thickness scalp avulsion injury, thorough wound debridement and immediate primary revascularization or a split-thickness skin graft may be necessary. Graft failure may be common situation thereby predisposing the individuals to unnecessary multiple operations. In the recent times, the use of omental graft has gained much popularity. In the present study, we describe an interesting case of chronic non healing scalp ulcer in a young woman who eventually underwent a free omental flap reconstruction with split-thickness skin graft and had satisfactory outcome.

Fulltext Scalp Wound Closure with K wires: An alternative easier method to scalp wound closure

Ramesh S, Ajik S

Med J Malaysia, 2012 Dec;67(6):629-30.

PMID: 23770963 MyJurnal

Scalp defects and lacerations present a reconstructive challenge to plastic surgeons. Many methods have been described from the use of skin grafting to rotation flaps. Here we present a method of closure of a contaminated scalp wound with the use of Kirschner wires. In our case, closure of scalp laceration was made possible with the use of 1.4 Kirschner wires and cable tie/ zip tie fasteners. The duration to closure of wound was 10 days. In reconstructing the scalp defect, this method was found to adhere to principles of scalp reconstruction. There were no post operative complications found from the procedure. On initial application on the edge of the wound, tension applied caused the K wires to cut through the wound edge. On replacement of K wires 1cm away from wound edge the procedure was not plagued by any further complication. In conclusion we find scalp closure with Kirschner wires are a simple and effective method for scalp wound closure.

Fulltext Can Brain Waves Really Tell If a Product Will Be Purchased? Inferring Consumer Preferences From Single-Item Brain Potentials

Goto N, Lim XL, Shee D, Hatano A, Khong KW, Buratto LG, et al.

Front Integr Neurosci, 2019;13:19.

PMID: 31316357 DOI: 10.3389/fnint.2019.00019

Recent research has shown that event-related brain potentials (ERPs) recorded while participants view lists of different consumer goods can be modulated by their preferences toward these products. However, it remains largely unknown whether ERP activity specific to a single consumer item can be informative about whether or not this item will be preferred in a shopping context. In this study, we examined whether single-item ERPs could reliably predict consumer preferences toward specific consumer goods. We recorded scalp EEG from 40 participants while they were viewing pictures of consumer goods and we subsequently asked them to indicate their preferences for each of these items. Replicating previous results, we found that ERP activity averaged over the six most preferred products was significantly differentiated from ERP activity averaged across the six least preferred products for three ERP components: The N200, the late positive potential (LPP) and positive slow waves (PSW). We also found that using single-item ERPs to infer behavioral preferences about specific consumer goods led to an overall predictive accuracy of 71%, although this figure varied according to which ERPs were targeted. Later positivities such as the LPP and PSW yielded relatively higher predictive accuracy rates than the frontal N200. Our results suggest that ERPs related to single consumer items can be relatively accurate predictors of behavioral preferences depending on which type of ERP effects are chosen by the researcher, and ultimately on the level of prediction errors that users choose to tolerate.

Naevus sebaceus is a cutaneous hamartoma with the potential of developing into benign or malignant neoplasms. Syringocystadenoma papilliferum (SCAP) have been reported to originate from naevus sebaceus. SCAP is a rare, benign adnexal skin tumour of apocrine or eccrine type of differentiation which typically presents as a nodule or a plaque on the scalp or face. We report a case of syringocystadenoma papilliferum arising in an undiagnosed pre-existing naevus sebaceus in a 56-year-old female.

MyJurnal

Different concentrations of N6-benzylaminopurine (BAP) and indole acetic acid (IAA) in Murashige and Skoog based medium were assessed for their effects on shoot multiplication, nodule-like meristem proliferation and plant regeneration of the Malaysian banana cultivars Pisang Mas, Pisang Nangka, Pisang Berangan and Pisang Awak. BAP at 1-14 mg L-1 with or without 0.2 mg L-1 IAA, or BAP at 7-14 mg L-1with the same concentration of IAA, was evaluated for shoot multiplication from shoot tips and the proliferation of nodule-like meristems from scalps, respectively. Plant regeneration from scalps was assessed using 1 mg L-1BAP and 0.2 mg L-1 IAA separately, or a combination of these two growth regulators. Data on shoot multiplication, the proliferation of nodule-like meristems with associated plant regeneration were recorded after 30 days of culture. A maximum of 5 shoots per original shoot tip was achieved on medium supplemented with BAP at 5 mg L-1 (Pisang Nangka), 6 mg L-1(Pisang Mas and Pisang Berangan), or 7 mg L-1 (Pisang Awak), with 0.2 mg L-1 IAA. BAP at 11 mg L-1 with 0.2 mg L-1 IAA induced the most highly proliferating nodule-like meristems in the four banana cultivars. Plant regeneration from scalps was optimum in all cases on medium containing 1 mg L-1 BAP and 0.2 mg L-1 IAA. This is the first report on the successful induction of highly proliferating nodule-like meristems and plant regeneration from scalps of the Malaysian banana cultivars Pisang Mas, Pisang Nangka, Pisang Berangan and Pisang Awak.

Successful use of tissue expanders depends on the quality of expanded tissue. This study evaluates the impact of anisotropic self-inflating tissue expander (SITE) on the biomechanics of skin. Two different SITE were implanted subcutaneously on sheep scalps; SITE that requires 30days for maximum expansion (Group A; n=5), and SITE that requires 21days for maximum expansion (Group B; n=5). Control animals (n=5) were maintained without SITE implantation. Young's Modulus, D-periodicity, overlap and gap region length, diameter, and height difference between overlap and gap regions on collagen fibrils were analyzed using atomic force microscopy. Histology showed no significant differences in dermal thickness between control and expanded skin of groups A and B. Furthermore, most parameters of expanded skin were similar to controls (p>0.05). However, the height difference between overlap and gap regions was significantly smaller in group B compared to both control and group A (p<0.01). Strong correlation was observed between Young's Modulus of overlap and gap regions of the control and group A, but not group B. Results suggest that a relatively slower SITE can be useful in reconstructive surgery to maintain the biomechanical properties of expanded skin.

Sultan Qaboos Univ Med J, 2018 Nov;18(4):e520-e523.

PMID: 30988973 DOI: 10.18295/squmj.2018.18.04.015

Objectives: This study aimed to investigate the off-label use of a combination calcipotriol plus betamethasone dipropionate (CBD) gel in the treatment of moderate-to-severe scalp seborrhoeic dermatitis (SSD).

Methods: This retrospective study involved 32 patients with SSD who were prescribed CBD gel at the Subang Jaya Medical Centre, Selangor, Malaysia, between January 2016 and December 2017. The Physician Global Assessment Scale was used to assess disease severity. Itching/discomfort was evaluated using a visual analogue scale.

Results: The mean age was 35.8 ± 6.9 years. Severe disease was seen in 53.1%. Complete clearance was recorded in 15.6%, 40.6% and 59.4% of patients at weeks two, six and 10, respectively. By week 10, 87.5% had achieved marked improvement. Both mean itching and discomfort scores significantly improved at weeks two, six and 10 (P <0.001). Better outcomes were significantly associated with disease duration and itching intensity and discomfort at presentation (P <0.050).

Conclusion: CBD gel should be considered as an option for SSD cases not adequately controlled by prior conventional treatment.

Fulltext Selection of Mother Wavelet Functions for Multi-Channel EEG Signal Analysis during a Working Memory Task

Al-Qazzaz NK, Bin Mohd Ali SH, Ahmad SA, Islam MS, Escudero J

Sensors (Basel), 2015;15(11):29015-35.

PMID: 26593918 DOI: 10.3390/s151129015

We performed a comparative study to select the efficient mother wavelet (MWT) basis functions that optimally represent the signal characteristics of the electrical activity of the human brain during a working memory (WM) task recorded through electro-encephalography (EEG). Nineteen EEG electrodes were placed on the scalp following the 10-20 system. These electrodes were then grouped into five recording regions corresponding to the scalp area of the cerebral cortex. Sixty-second WM task data were recorded from ten control subjects. Forty-five MWT basis functions from orthogonal families were investigated. These functions included Daubechies (db1-db20), Symlets (sym1-sym20), and Coiflets (coif1-coif5). Using ANOVA, we determined the MWT basis functions with the most significant differences in the ability of the five scalp regions to maximize their cross-correlation with the EEG signals. The best results were obtained using "sym9" across the five scalp regions. Therefore, the most compatible MWT with the EEG signals should be selected to achieve wavelet denoising, decomposition, reconstruction, and sub-band feature extraction. This study provides a reference of the selection of efficient MWT basis functions.

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.

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.

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.

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.
