Dental prosthesis ingested and impacted in the esophagus and orolaryngopharynx

Abdullah BJ, Teong LK, Mahadevan J, Jalaludin A

J Otolaryngol, 1998 Aug;27(4):190-4.

PMID: 9711512

Impacted foreign bodies in the trachea and esophagus are common. In the esophagus, these are usually bones, while for the trachea, it is commonly some form of seed or nut. The incidence of impacted dental prostheses is not highlighted in the literature. They usually have a definite history of ingestion, frequently during trauma, seizures, or sleep. Prompt management in a safe and effective manner is required if significant morbidity, and even mortality, is to be avoided.

PMID: 2269916

The objective of this report was to determine the radiographic patterns of alveolar bone loss in early-onset periodontitis (EOP) cases in a selected Malaysian population. The radiographs of 55 cases of EOP patients were examined and the radiographic patterns were classified as follows: Type I: bone destruction on first molars and/or incisors only; Type II: bone destruction on first molars and/or incisors and several additional teeth (less than 14 teeth); Type III: generalized bone destruction (greater than 14 teeth), but with involvement noticeably more extensive on the first molars and/or incisors; Type IV: generalized bone destruction (greater than 14 teeth), but with no more bone loss on the first molars and/or incisors than on other involved teeth. Sex, age, and missing teeth were also recorded. Out of 55 cases, 47 cases, 22 males and 25 females, were classified into the types mentioned above; the remaining 8 cases were excluded due to too many missing teeth. It was found that 7 (14.9%) were Type I; 12 (25.5%) were Type II; 7 (14.9%) were Type III; and 21 (44.7%) were Type IV. There was a predominance of first molar/incisor involvement in Types I, II, and III with the maxillary first molars most frequently involved followed by the mandibular central incisors. Type I occurred in the younger age group and Types II, III, and IV mainly in the older age group. It was concluded that EOP in this patient sample resembled that of western society.

Prasad U, Doraisamy S

Eur J Surg Oncol, 1991 Oct;17(5):536-40.

PMID: 1936303

Five rare cases of nasopharyngeal carcinoma with optic nerve involvement are reported. Computerised Tomographic Scan (CT Scan) studies were performed in four of them. Evidence of intracranial spread of the tumour, from the roof of the fossa of Rosenmuller to the apex of the orbit through the cavernous sinus, was noted in three patients. In one of them there was extracranial extension of the tumour, to the orbit through the posterior ethmoid.

Fulltext Unicystic ameloblastoma: a new entity?

Zain R

Med J Malaysia, 1986 Dec;41(4):370-3.

PMID: 3670162

This article consists of two selected case reports of a recently named odontogenic tumour, unicystic ameloblastoma. The clinical and radiographic findings of the two cases mimic that of odontogenic cysts but not dentigerous cysts as in most reported, cases. Histologically, either a normal or ameloblastomatous cyst lining is evident. Other features of ameloblastoma are present within the cyst wall or as luminal nodules within the cystic space. A review of the literature indicates that this is a non-aggressive tumour with a low recurrence rate.

Fulltext Germinoma of the basal ganglia and thalamus--CT and MRI findings

Wong LW, Jayakumar CR

Singapore Med J, 1997 Oct;38(10):444-6.

PMID: 9529959

A case of germinoma originating in the basal ganglia and thalamus is presented. This tumour most commonly originates during childhood and adolescence, at pineal and suprasellar regions. In the early stages, the diagnosis of germinoma in the basal ganglion and thalamus is difficult because of its rarity and non-specific findings. The computed tomography (CT) and magnetic resonance imaging (MRI) findings though non-diagnostic, are discussed here. A few differential diagnoses had been discussed with radiological abnormality. Open biopsy done in this case proved to be two-cell pattern germinoma. Early detection of the tumour is desirable, since this tumour is highly sensitive to radio and chemotherapy and is potentially curable. Our patient was treated with combined chemotherapy and the response was well and no residual tumour or recurrence was seen on the repeated imaging modality, however his neurological deficits remained unchanged.

Prevalence and patterns of tooth agenesis among Malay children

Mani SA, Mohsin WS, John J

Southeast Asian J. Trop. Med. Public Health, 2014 Mar;45(2):490-8.

PMID: 24968691

Tooth agenesis in Malay children, hitherto unreported, was assessed retrospectively from orthopantomograms of 834 healthy children aged 12-16 years who attended the Dental Clinic of Universiti Sains Malaysia. All teeth, including third molars, were assessed for agenesis. On an average, 2.3 teeth were missing per child. Missing third molars were found in 25.7% of children with one or two third molars found to be missing in 18.3% of children. Three point two percent of children had missing teeth other than third molars. After third molars, the upper lateral incisors were found to be the most common missing tooth (1.7%), followed by upper and lower second premolars (1.5%). Eight missing upper canines were also seen (1%). Bilateral agenesis was more common than unilateral agenesis. There were no significant differences between males and females. There was a significant difference between missing teeth between the maxilla and the mandible and right and left side, with more missing teeth in the maxilla and on the right side. The odds of any 3rd molar missing were increased 3.3 times when there was any other missing tooth. In conclusion, the prevalence of tooth agenesis among the studied population was within the normal range, but less than some Asian countries. Unlike other Asian countries, the upper lateral incisor was the most common missing tooth. The prevalence of maxillary canine agenesis was higher than most previous reports. Missing teeth were associated with missing third molars, which is likely due to a genetic abnormality.

Infratemporal fossa abscess is a rare and challenging condition to diagnose and manage. A few reported cases have been mostly due to odontogenic infections and were managed by external or intraoral drainage. This is the first reported case of an infratemporal fossa abscess that was successfully managed by endoscopic drainage via a transmaxillary approach.

Kumaresan R, Cugati N, Chandrasekaran B, Karthikeyan P

J Investig Clin Dent, 2016 Feb;7(1):102-9.

PMID: 25048008 DOI: 10.1111/jicd.12116

OBJECTIVE: To evaluate the reliability and validity of Demirjian's, Willems, Nolla's, Haavikko's, and Cameriere's radiographic methods of dental-age estimation in a population of Malaysian children.

METHODS: A total of 426 dental panoramic radiographs of 5-15-year-old Malaysian children were included in the study. The mean age error and absolute age error for all the methods were calculated and their usability analyzed.

RESULTS: The Nolla, Willems. and Demirjian methods overestimated the dental age with a mean of 0.97, 0.54, and 0.54 years, respectively, while the Cameriere and Haavikko methods underestimated by 0.41 and 1.31 years, respectively. The Cameriere method was highly precise and accurate in the population of Malaysian children, whereas the Haavikko and Demirjian methods were the least precise and accurate.

CONCLUSIONS: The Cameriere method of dental-age estimation is highly valid and reliable for Malaysian population, followed by the Willems and Nolla methods.

Practical relevance of pattern uniqueness in forensic science

Jayaprakash PT

Forensic Sci Int, 2013 Sep 10;231(1-3):403.e1-16.

PMID: 23849815 DOI: 10.1016/j.forsciint.2013.05.028

Uniqueness being unprovable, it has recently been argued that individualization in forensic science is irrelevant and, probability, as applied for DNA profiles, should be applied for all identifications. Critiques against uniqueness have omitted physical matching, a realistic and tangible individualization that supports uniqueness. Describing case examples illustrating pattern matches including physical matching, it is indicated that individualizations are practically relevant for forensic science as they establish facts on a definitive basis providing firm leads benefitting criminal investigation. As a tenet of forensic identification, uniqueness forms a fundamental paradigm relevant for individualization. Evidence on the indeterministic and stochastic causal pathways of characteristics in patterns available in the related fields of science sufficiently supports the proposition of uniqueness. Characteristics involved in physical matching and matching achieved in patterned evidence existing in the state of nature are not events amenable for counting; instead these are ensemble of visible units occupying the entire pattern area stretching the probability of re-occurrence of a verisimilitude pattern into infinity offering epistemic support to uniqueness. Observational methods are as respectable as instrumental or statistical methods since they are capable of generating results that are tangible and obviously valid as in physical matching. Applying the probabilistic interpretation used for DNA profiles to the other patterns would be unbefitting since these two are disparate, the causal pathways of the events, the loci, in the manipulated DNA profiles being determinable. While uniqueness enables individualizations, it does not vouch for eliminating errors. Instead of dismissing uniqueness and individualization, accepting errors as human or system failures and seeking remedial measures would benefit forensic science practice and criminal investigation.
