Frey Syndrome Complicating Parotidectomy: A Case Report And Review Of Literature
The parotid gland is one of the major salivary glands located on the face. It is commonly affected by diseases necessitating its surgical removal. The facial nerve is in intimate contact with this structure and can easily be damaged during operation on this gland. Parotidectomy is the surgical operation done to remove part or the whole of the parotid gland. There are several types of parotidectomies. These may be superficial, total, total conservative, radical or extended radical. A number of complications may ensue following this procedure. Frey syndrome is one of such complications but uncommon. It is therefore the aim of this paper to present this index case with a review of literature.

Ethnic Identity and Local Government Responsiveness in Taiwan
Countless studies have shown that local officials are less responsive to ethnic minority citizens. Surprisingly, we find no similar pattern of discrimination by Taiwanese local officials. In an online contacting experiment, we send citizen service requests to the websites of 358 township and district chiefs, randomly varying the name of the putative citizen to reflect an indigenous or an ethnically Chinese identity and collecting data on officials\u27 responses. We find that officials are equally responsive to both identities. Drawing on in-depth interviews and nonparticipant observation in government service centers, we attribute this surprising finding to institutional elements of Taiwan\u27s local bureaucracy that limit the impact of individual-level bias. However, our research provides preliminary evidence that local governments are generally less responsive in indigenous areas. While clearly defined procedures may prevent discrimination against indigenous individuals, interregional differences in local state capacity can nonetheless produce unequal experiences with local governance
Optical method for inspecting surface defects inside a small bore
Most automotive powertrain parts made of castings have surface defects such as pores. However, detecting pores inside small diameter bores is a challenge because of the limited dimensional accessibility. Adding to this difficulty is the auto industry's desire to conduct the porosity inspection in-line, i.e. within the machining production cycle time of a part. A technique or equipment that meets these requirements currently does not exist. In order to meet these demands, it is necessary to develop an entire new methodology to inspect the inner surface of small diameter bores. This paper presents an innovative methodology to inspect the porosity of the inner surface of small bores and to provide their characteristics such as size and location. A prototype measurement system was built and tested in the lab. Experimental results showed the proposed method to be reliable and consistent.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/85431/1/mst10_1_015704.pd
Thermal Comfort Analysis on the Residential Buildings in Sarawak
Thermal comfort is a subjective response that reflects the contentment between one’s state of mind and the current environment. The energy consumption of the building sector has rapidly increased due to improved living standards and rising expectations of residents regarding thermal comfort. Mechanical ventilation, especially air conditioning systems, is essential for hot and humid countries aiming to achieve an ideal indoor comfort condition. However, such cooling systems often consume a significant amount of electricity, which contradicts the concept of energy conservation. Therefore, thermal comfort assessment is a method that can be employed to address this issue. Evaluating the thermal perception of occupants can subsequently facilitate more efficient electricity usage, aligning with the goal of energy conservation. In this study, a thermal comfort analysis was conducted on free-running residential buildings in Sarawak. These buildings were naturally ventilated with minimal use of mechanical ventilation systems. Physical measurements and subjective assessments were employed to evaluate the thermal responses of the residents based on various sensation and comfort scales, including the ASHRAE scale, Bedford scale, thermal acceptability scale, and thermal preference scale. Additionally, the widely used PMV model was utilized to predict the thermal sensation experienced by the residents. The results of the study indicated that the Bedford scale exhibited the highest percentage of acceptable responses, followed by the ASHRAE scale, thermal acceptability scale, and thermal preference scale. The PMV model was observed to overpredict the residents’ thermal responses. The comfort temperatures derived from the study were 27.5 ∘C, 28.1 ∘C, and 26.2 ∘C according to the ASHRAE scale, Bedford scale, and PMV model, respectively. Based on the actual percentage of dissatisfaction that ensures 80% satisfaction, the acceptable indoor temperature range was found to be 27.3 ∘C to 29.6 ∘C. Similarly, the acceptable range for relative humidity was 74.0% to 92.0%, and for air velocity, it was 0.18 m/s to 0.66 m/s.

Synchronous congenital nasal piriform aperture stenosis and atresia : A rare accompaniment of mid-facial dystosis and cause of neonatal upper airway obstruction
Congenital nasal piriform aperture stenosis (CNPAS) is a recently distinguished clinical entity that causes airway compromise in neonate as a result of a narrowing of the nasal piriform aperture. It may be bilateral or unilateral. Often considered as a form of holoprosencaphaly. Being the narrowest part of the nasal airway, any slight reduction in its cross sectional area will profoundly increase the nasal airway resistance with the attendant clinical challenges. Readily making an accurate clinical diagnosis may be very challenging when CNPAS occurs in the setting of a craniofacial dysostosis. This communiqué is aimed at increasing awareness among clinicians involved in paediatric care of the clinical entity congenital nasal
piriform aperture stenosis and atresia presenting atypically as synchronous disorder with midfacial dysostosis. Hence, it should be kept in mind as a rare mimicker of bilateral choanal atresia and requires mandatory high resolution computerized tomography to confirm the diagnosis
Rosai-Dorfman Disease: A Diagnostic Albatross in a Female Patient with Bilateral Persistent Neck Masses. A Case Report
RosaiDorfman disease (sinus histiocytosis with massive lymphadenopathy) is an uncommon benign and often self limiting lymphoproliferative disease of unknown aetiology which was first described by Rosai and Dorfman in 1969. It usually presents with a multiple progressive painless bilateral cervical lymphadenopathy, low grade fever, polyclonal hypergammaglobulinemia and raised erythrocyte sedimentation rate. Extranodal diseases are uncommon but have been documented. Due to the rarity of this condition, the diagnosis may not be suspected clinically and fine needle aspiration cytology of neck nodes may miss the diagnosis. In this study, we present a 24 year old female who presented with bilateral cervical lymphadenopathy and right breast lump since childhood
