Killian-Jamieson (K-J) diverticulum is a rare cervical oesophageal diverticulum, less commonly encountered compared with Zenker's diverticulum (ZD). We report a case of K-J diverticulum in a 52-year-old lady who presented with sensation of lump in the neck and food stuck in the throat of 5 years duration. Esophagogram showed a large rightsided pharyngoesophageal diverticulum which was confirmed on endoscopy. The patient underwent a diverticulopexy and recovered without complications. Her symptoms had improved. In this report, we review the literature and describe our surgical technique.

Wind tunnel experimental research on the effect of col topography on wind environment

Liu Hui

Sains Malaysiana, 2016;45:99-107.

Investigation of meteorological disasters caused by small-scale topography shows that flashover due to wind age yaw occurred quite often where col topography existed. Considering that the distribution pattern of wind profile at different locations of a col topography is not clear, this paper, with wind tunnel tests, studied the influenced of such topographic features of a col as hill slope and valley mouth width on the wind profile at different locations. The results of wind tunnel tests indicated that over-hill wind has a stronger effect on wind velocity correction coefficient than does valley wind, that compared to flat terrain wind velocity, the maximum speed-up amplitude of wind velocity at valley throat and hill summit reach 33 and 53%, respectively, apparently higher than 10% specified in Codes, that wind velocity at valley throat increases with the increase of hill slope and decreases with the increase of valley mouth width, that wind velocity in the valley basically does not go up when the slope of one hill side is smaller than 0.1 and that wind velocity at the same non-dimensional height of a 3D hill summit increases with the increase of hill height.

Lingual tonsil is a part of Waldeyer’s ring. It consists of lymphoid follicles and subject to proliferation and hypertrophy. Palatine tonsillitis, by far is the commonest cause of odynophagia originating from oropharyngeal region. Lingual tonsillitis is a rare occurrence. We reported a patient who presented with severe odynophagia after two months of palatine tonsillectomy. Examination revealed the lingual tonsils were inflamed and covered with exudates.

MyJurnal

Numerical studies of blood flow system of aorta coronary sinus conduit were carried out using ANSYSTMCFD simulation. A different model of conduit, which differs in the inlet diameter, was investigated. Theinvestigated inlet diameters are 3 mm, 4 mm and 5 mm. Pressure drop from 80 mmHg to 15 mmHgwas achieved for all the models. The comparison chart was produced to compare the pattern of pressurereduction as well as velocity distribution in each model. From the analysis of coronary sinus conduit,it was found that a narrow tube needs to be incorporated into the conduit produced. This is to inducea venturi effect to reduce the pressure drop of blood within a specific throat length. As conclusion, amodel of 3 mm inlet and a throat diameter of 1.13 mm show satisfactory result for pressure reductionfrom 80 mmHg to 15 mmHg. This particular model also has a lower peak velocity at the inlet zone ofthe throat section, which is more preferable in terms of Reynolds number.

Tornwaldt's (Thornwaldt's) or nasopharyngeal cyst is an uncommon developmental
benign cyst located in the midline postero-superior wall of nasopharynx. Incidence reported in
general population is 0.06%. It occurred in the potential space due to outpouching of ectoderm into
the pharyngobasilar fascia at the site where notochord attached to pharyngeal ectoderm. (Copied from article).

Cotard delusion in a depressed patient: "My throat is missing!"

Huan WY, Wan Azlan WA, Lee YT

Asia Pac Psychiatry, 2023 Mar;15(1):e12524.

PMID: 36575636 DOI: 10.1111/appy.12524

Cotard's syndrome is a rare neuropsychiatric disorder characterized by marked nihilistic delusions. This report describes an Indonesian woman from a small town in Malaysia who was diagnosed with depression and Cotard's delusion. The diagnosis was confirmed after thorough history-taking, clinical examination, and relevant laboratory tests. Herein, we highlight the unique psychopathology of a possible Cotard's syndrome subtype and efficacy of pharmacological combination strategies, rather than monotherapy and electroconvulsive therapy, for its treatment.

Fulltext Isolation of measles virus from clinical specimens using B95a and Vero/hSLAM cell-lines

Keniscope C, Juliana R, Subri H, Shangari SR, Wan Nor Azlina WA, Hamizah A, et al.

Med J Malaysia, 2009 Mar;64(1):37-40.

PMID: 19852319 MyJurnal

The clinical presentation of acute measles is normally quite typical, especially in the presence of Koplik's spots, that laboratory test is seldom required to confirm the diagnosis. However, with wide measles vaccination coverage and the extensive use of immunosuppressive chemotherapy, the diagnosis of atypical manifestations of acute measles may require laboratory confirmation. When compared with B95a cell-line, this study shows that the Vero/hSLAM cell-line is sensitive and is recommended for use in the primary isolation of wild-type measles virus from clinical specimens. Throat swab and urine specimens are the clinical specimens of choice and both are recommended for optimal isolation of measles virus from patients suspected of acute measles virus infection.

Fulltext How does mandibular advancement with or without maxillary procedures affect pharyngeal airways? An overview of systematic reviews

Tan SK, Leung WK, Tang ATH, Zwahlen RA

PLoS One, 2017;12(7):e0181146.

PMID: 28749983 DOI: 10.1371/journal.pone.0181146

BACKGROUND: Mandibular advancement surgery may positively affect pharyngeal airways and therefore potentially beneficial to obstructive sleep apnea (OSA).

OBJECTIVE: To collect evidence from published systematic reviews that have evaluated pharyngeal airway changes related to mandibular advancement with or without maxillary procedures.

METHODOLOGY: PubMed, EMBASE, Web of Science, and Cochrane Library were searched without limiting language or timeline. Eligible systematic reviews evaluating changes in pharyngeal airway dimensions and respiratory parameters after mandibular advancement with or without maxillary surgery were identified and included.

RESULTS: This overview has included eleven systematic reviews. Maxillomandibular advancement (MMA) increases linear, cross-sectional plane and volumetric measurements of pharyngeal airways significantly (p<0.0001), while reducing the apnea-hypopnea index (AHI) and the respiratory disturbance index (RDI) significantly (p<0.0001). Two systematic reviews included primary studies that have evaluated single-jaw mandibular advancement, but did not discuss their effect onto pharyngeal airways. Based on the included primary studies of those systematic reviews, single-jaw mandibular advancement was reported to significantly increase pharyngeal airway dimensions (p<0.05); however, conclusive long-term results were lacking.

CONCLUSION: MMA increases pharyngeal airway dimensions and is beneficial to patients suffering from OSA. However, more evidence is still needed to draw definite conclusion related to the effect of single-jaw mandibular advancement osteotomies on pharyngeal airways.

Fulltext Radio-opacity of commonly consumed bony fish in Kelantan, Malaysia

Irfan M, Ahmad Helmy AK, Wan Shah Jihan WD

Med J Malaysia, 2012 Oct;67(5):491-3.

PMID: 23770865

Fish is one of the major sources of protein among Malaysians. This has made incidents of fish bones lodged in the throat fairly common clinical problems. Plain radiograph, which is the first line of imaging in such cases, has been reported to have low sensitivity. Besides the location, the degree of radio-opacity of the bone is another important factor and is species dependent. This study was undertaken to determine the radio-opacity of bones from commonly consumed fish in Malaysia. A total of 15 types of fish were identified, six of them were opaque even when embedded and three were visualized in the simulated airway. In terms of radio-opacity, the commonly consumed fish in Malaysia possessed opaque bones and this fact can help doctors identify the location of the foreign body in the throat.
