1.Human otoacariasis in a 40-year old Filipino male: A case report.
Journal of the Philippine Medical Association 2022;100(2):53-58
A 40-year old male, Filipino, farmer, from
Bakun, Benguet, presented with a 9 months history
of itchiness of right ear. He reported that he was able
to collect 4-5 insects every time he cleans his ear.
Consult was done with an Ears, Nose and Throat
specialist and video-otoscopic examination
revealed multi pie animate foreign body (mites) at
different stages of development. The patient
underwent 5 sessions of ear flushing with warm
water at intervals of 2 weeks for 3 months. Collected
insects were referred to an entomologist and were
identified as Suadasia pontifica Oudemans,
belonging to family: Acaridae. Follow up consult
after 5 sessions of ear flushing revealed complete
removal of mite infestation of his right ear. Patient
was instructed to do ear flushing twice daily using
warm water mixed with 70% isopropyl alcohol to
eradicate any eggs left behind. No other medications
were given. Based on Philippine Journal of
Otolaryngology - Head and Neck Surgery, Health
Research and Development Information Network,
and Cochrane Database of Systematic Reviews, this
is the first reported case of human otoacariasis in
the Philippines.

2.An Ecological Study on the House Dust Mite.
Korean Journal of Dermatology 1984;22(3):286-294
In this study, the authors attempted to investigate distribution of the house dust mites in Korea on a nationwide scale. Mites were isolated and classified from 211 house dust samples which were collected from 7 urban areas and 3 rural areas. The result were as follows: 1) Nineteen species of mites were identified in this study including 4 new species which were not recorded in Korea. 2) The most frequent house dust mites were Pyroglyphid mites. Among then, Derntatophagoides farinae was found to be dominant species in Korea since this species was more widely distributed and more frequently found than D. pteronyssinus, 3) The occurence rates of Dermatophagoides sp. in the urban areas were higher than that in the rural areas, but vice versa in the occurence rates of other mites accidently found in the dust samples.

Korean Journal of Preventive Medicine 1968;1(1):37-42
Authors studied on the Acaroid mite in the food, and the following results were obtained. 1) 6 species of Acaroid mite were found among twelve kinds different types of food. a. Tyrophagus dimidiatus, b. Glycyphagus destructor, c. Glycyphagus domesticus, d. Hoshikadania konoi, e. Acarus siro, f. Carphoglyphus lactis. 2) Acaroid mite were not found in the wheat flour and magalin among the twelve different kinds. 3) Acaroid mit were distributed at higher rate in the pollack(94%), cuttle fish(77%) and anchovy(50%).

BACKGROUND: Scabies is a contagious skin infestation characterized clinically by nocturnal pruritus, visible burrows and contagiousness. Dermoscopy has been suggested as an alternative for diagnosing scabies. But, there have been few well-designed studies evaluating the diagnostic accuracy of dermoscopy. OBJECTIVE: We tried to confirm the diagnostic accuracy of dermoscopy for diagnosing scabies. We also tried to demonstrate specific circumstances in which dermoscopic identification of mites ("with dermoscopy") is more useful in diagnosing scabies, and to identify the specific clinical findings that could be used as a possible marker in diagnosing scabies. METHODS: We compared the scraping procedure "with dermoscopy" and "without it" in 49 patients, measuring the duration and outcome of each procedure. Also, we tried to find the specific clinical factors associated with our objects. RESULTS: The skin scraping "with dermoscopy" was superior to "without it" with respect to the duration and accuracy of the procedure. A history of previous steroid treatment was associated with the superiority of dermoscopy. The correlation between the presence of visible burrows and the positive outcomes of "with dermoscopy" was statistically significant. CONCLUSION: Skin scraping with dermoscopy is implicated as the diagnostic method of choice for scabies at the present time. Dermoscopy is especially useful in diagnosis of incognito scabies. In addition, the presence of visible burrows could be a reliable positive marker of scabies in the absence of dermoscopy or microscopy data.

Rosacea is a chronic and recurrent inflammatory eruption of the flush areas of the face, particularly the nose, which is characterized by erythema, papules, pustules, and telangiectasia. Although the precise etiology remains as a mystery, various factors including genetic disposition, vascular dysfunction, solar elastotic degeneration, gastrointestinal disturbance, hormonal influences, increased humoral vasoactive mediators, and Demodex folliculorum infestation have been suspected of contributing to this condition. In recent study, it has been reported that a high density of Demodex folliculorum may have a pathogenic role in rosacea, especially in the development of inflammatory lesions. We report an unilateral rosacea-like chronic dermatitis of the left side of the face which was shown to harbor many Demodex folliculorum mites.

This study was conducted to investigate distribution of the house dust mites in the bedroom of allergic rhinitis patients in Pusan. From July to December 1995, 51 dust samples were drawn from the bedroom of the patients by using electronic vaccum cleaner. House dust mites were isolated from 50mg dust by applying the modified wet sieving method. The results were as follows: 1 Out of a total 49 dust samples(96.1%) were isolated house mites. 2 Total 977 mites were collected and identified the most prevalent house mites was Pyroglypidae mite with 92.2%. Among them D.pteronyssinus was predominant species. 3 In 1gm of the house dust, 100-499 mites were found in 17 samples(33.3%), more then 500 mites in 12 samples (23.6%). 4 The density of Pyoglypidae mite was close associated with the month. 5 The density of house dust mite was not affected by the type of house, region and the relative humidity of the bed room

Korean Journal of Dermatology 1974;12(1):21-26
Frorn August to December 1973, 189 cases of scabies were examinecl by Muller's method and following results were obtained: 1) 91 cases (52. 6%) of 172 were confirmed by detecting mite. 2) From the reexamination of samples, adult form(58.2%), larva(52.7%), egg(41.8%), egg shell(30.8%) and scybala(29.7%) were identified in order and egg shell and scybala were also diagnostic. 3) Confirmed scraping lesions were burrow(61. 8%),papule(29.4%), vesicle(5.9%) pustule(2.9%), in order of frequency. 4) Adult Sarcoptes was found in 27 cases(64.3%) of 42 examined with burrows and in 13 cases(65%) of 20 with papules. 5) Mean of incubation period was 26.6 days in 14 cases.
