Concha bullosa in chronic sinusitis.

Sinusitis is an important cause of morbidity and one of the major sources of income loss. Anatomical variations of the nose have been reported to predispose to sinusitis. These variations include concha bullosa, nasal septal deviation and oversized bulla. The aim of this study was to determine the proportion and the distribution of concha bullosa in patients with chronic sinusitis and to determine the relationship between concha bullosa and age, sex, ethnicity. A cross-sectional study was conducted at the Department of Ear, Nose and Throat in Kuala Lumpur Hospital (HKL). Data was collected retrospectively using a pretested proforma. All patients who underwent Sino nasal surgery between January 1999 and December 2000 and whose preoperative CT scans were available were included in the study. The CT scans were reviewed. Analysis was carried out using Statistical Package for Social Sciences. Out of 146 patients who underwent sinonasal surgery between January 1999 and December 2000, 101 (69.2% preoperative CT scans of these patients were available and these were reviewed. The proportion of patients with concha bullosa was 49.5%. The results showed that there was significant relationship between presence of concha bullosa and age and sex. The overall mean age of patient with concha bullosa was 35.7 years (95% CI 12.1-39.3) and ranged from 11-years to 56-years. The mean age of respondents with concha bullosa was significantly lower than patients without concha bullosa 41.98 (95% CI 37.6-46.3; t-test = 2.221; df=99; p < 0.05). Concha bullosa was significantly more in females (66.0%) compared to males (chi2 = 4.465, df=1, p < 0.05). There was no significant relationship between presence of concha bullosa and ethnicity.

A prospective evaluation of foreign bodies presenting to the Ear, Nose and Throat Clinic, Hospital Kuala Lumpur.

The results of a prospective study of 94 patients with history of ear, nose or aerodigestive tract foreign bodies were analysed. Sixty six to 94% of patients presented within 24 hours to a primary care doctor, 80 to 94% was referred to the ENT Department within 24 hours and 89 to 93% of patients had their foreign bodies removed within 24 hours. Overall, 58% of aural foreign bodies, 67% nasal foreign bodies and 94% of aerodigestive tract foreign bodies were removed within 48 hours of insertion. As a result of the prompt removal of foreign bodies in the majority of patients, no significant complications occurred. Foreign bodies in the aerodigestive tract tend to present earlier and more promptly removed compared with ear and nose foreign bodies. There was a significantly higher proportion of foreign body in the right ear and nostril compared to the left.

Management of osteonecrosis of the femoral head.

Osteonecrosis of the femoral head continues to pose a therapeutic challenge to orthopedic surgeons. This pathologic process results from the death of living components of bone from mechanical and biologic factors. Diagnosis, clinical symptoms, and classification systems are discussed. Several treatment regimens and their controversies are explored in this article.

The UMLS Knowledge Source server.

The UMLS Knowledge Source server is an evolving tool for accessing information stored in the UMLS Knowledge Sources. The system architecture is based on the client-server paradigm wherein remote site users send their requests to a centrally managed server at the U.S. National Library of Medicine. The client programs can run on platforms supporting the TCP/IP communication protocol. Access to the system is provided through a command-line interface and through an Application Programming Interface.

Endometrial adenocarcinoma arising in a secretory endometrium.

Endometrial adenocarcinoma in young women below the age of 45 years and in a functioning endometrium is rare. We present the case of a 41-year-old woman, who without clinical risk factors, was found to have a focal well-differentiated endometrial adenocarcinoma in the background of a histologically secretory endometrium. Endometrial evaluation for abnormal vaginal bleeding in a young ovulating female and thorough examination of the endometrium in its entirety in the hysterectomized uterus are reemphasized.

UMLS knowledge for biomedical language processing.

This paper describes efforts to provide access to the free text in biomedical databases. The focus of the effort is the development of SPECIALIST, an experimental natural language processing system for the biomedical domain. The system includes a broad coverage parser supported by a large lexicon, modules that provide access to the extensive Unified Medical Language System (UMLS) Knowledge Sources, and a retrieval module that permits experiments in information retrieval. The UMLS Metathesaurus and Semantic Network provide a rich source of biomedical concepts and their interrelationships. Investigations have been conducted to determine the type of information required to effect a map between the language of queries and the language of relevant documents. Mappings are never straightforward and often involve multiple inferences.

Rhabdomyosarcoma of the middle ear and mastoid in children.

Three cases of embryonal rhabdomyosarcoma in the middle ear and mastoid in children are presented. Diagnosis was confirmed by histopathology. A multidisciplinary approach employing surgery, chemotherapy and radiation therapy is the method of choice in the management of this rare and highly lethal condition.

Cryosurgery for intraepithelial neoplasia of the cervix.

Cryosurgery was used as the means of therapy in 203 patients with intraepithelial neoplasia of the cervix. One hundred and ten patients were diagnosed by colposcopy, directed biopsy, and endocervical curettings. The histological diagnosis varied between mild dysplasia and carcinoma in situ. Carbon dioxide gas was used as the refrigerant. Cryosurgery was effective in 96% of the 203 patients treated. The main causes of failure were: lack of colposcopy, endocervical involvement, the size of the lesion, single freeze, and severity of the lesion. False-negative Pap smear rates were 12.8%. The results suggest that carefully selected patients with early intraepithelial neoplasia can be treated adequately by cryosurgery with low incidence of recurrence and without risk and the cost of hospitalization. Meanwhile, this study reaffirms the need to perform biopsies and investigate any abnormal changes of the cervix, even in the absence of an abnormal cytology smear, before any treatment.
