Preventing nosocomial infections: improving compliance with standard precautions in an Indonesian teaching hospital.

Standard precautions can prevent transmission of micro-organisms. This study investigated hand hygiene, handling of needles and use of personal protective equipment in an Indonesian teaching hospital, and performed a multi-faceted intervention study to improve compliance. An intervention was performed in an internal medicine ward and a paediatric ward, consisting of development of a protocol for standard precautions, installation of washstands, educational activities and performance feedback. Before, during and after the intervention, observers monitored compliance with hand hygiene, safe handling of needles and use of gloves, gowns and masks. A gynaecology ward served as the control. Unobtrusive observations were performed to check for an influence of the observers on the overt observations. In total, 7,160 activities were observed. Compliance with hand hygiene increased from 46% to 77% in the internal medicine ward and from 22% to 62% in the paediatric ward. Before the intervention, no safe recapping of needles was recorded in either ward. After the intervention, 20% of needles were recapped safely. Inappropriate gown use decreased in the internal medicine ward. There were no significant changes in use of gloves and masks. There may have been an effect of the overt observations in the paediatric ward, but there was no effect in the internal medicine ward. There were no significant changes in the control ward, except for a decrease in the use of gloves. In conclusion, compliance with hand hygiene procedures improved significantly due to an intervention project focused on education and improved facilities. Compliance with safe handling of needles improved slightly due to introduction of the one-handed method for safe recapping of used needles.

Surveillance of healthcare-associated infections in Indonesian hospitals.

A cross-sectional surveillance of healthcare-associated infections (HAIs) and exposure to risk factors was undertaken in two Indonesian teaching hospitals (Hospitals A and B). Patients from internal medicine, surgery, obstetrics and gynaecology, paediatrics, a class department and intensive care were included. Patient demographics, antibiotic use, culture results, presence of HAI [phlebitis, surgical site infection (SSI), urinary tract infection (UTI) and septicaemia] and risk factors were recorded. To check for interobserver variation, a validation study was performed in Hospital B. In Hospitals A and B, 1,334 and 888 patients were included, respectively. Exposure to invasive devices and surgery was 59%. In Hospital A, 2.8% of all patients had phlebitis, 1.7% had SSI, 0.9% had UTI and 0.8% had septicaemia. In Hospital B, 3.8% had phlebitis, 1.8% had SSI, 1.1% had UTI and 0.8% had septicaemia. In the validation study, the prevalence as recorded by the first team was 2.6% phlebitis, 1.8% SSI, 0.9% UTI and no septicaemia, and that recorded by the second team was 2.2% phlebitis, 2.6% SSI, 3.5% UTI and 0.9% septicaemia. This study is the first to report on HAI in Indonesia. Prevalence rates are comparable to those in other countries. The reliability of the surveillance was insufficient as a considerable difference in prevalence rates was found in the validation study. The surveillance method used is a feasible tool for hospitals in countries with limited healthcare resources to estimate their level of HAI and make improvements in infection control. Efficiency can be improved by restricting the surveillance to include only those patients with invasive procedures. This can help to detect 90% of all infections while screening only 60% of patients.

Maxillary sinus cavernous hemangioma: a rare entity.

Vascular lesions of the sinonasal tract are rare. These lesions do not have typical signs or symptoms. They may present insidiously with minimal symptoms. A high index of suspicion and a good preoperative evaluation are needed for diagnosis. No standard surgical approach is indicated. We report a case of cavernous hemangioma of the maxillary sinus in an adult male. We present the diagnostic work-up and discuss the differential diagnosis and potential therapeutic approaches.

Comparative analysis between Pseudomonas aeruginosa genotypes and severity of symptoms in patients with unilateral or bilateral otitis externa.

Random amplified polymorphic DNA (RAPD) analysis was done on 32 isolates of Pseudomonas aeruginosa. These isolates were obtained from 22 patients who presented to the emergency room in a major medical center in Beirut, Lebanon, during a 5-month period with the diagnosis of either unilateral or bilateral otitis externa. Patients had yellowish to greenish discharge, moderate to severe external auditory canal swelling, moderate to severe pain, and periauricular cellulitis. None of these patients had intrinsic predisposing factors. An ear swab was obtained from both ears of patients, cultured on trypticase soy agar. P. aeruginosa was identified on the basis of pyocyanine production and API identification kits. RAPD analysis was done by using two primers (10 mer and 21 mer primers) and appropriate PCR conditions on extracted DNA. Our data have shown 23 RAPD patterns (A-W) distributed among the 32 P. aeruginosa isolates. RAPD patterns were reproducible. Twenty of 32 isolates were recovered from 10 patients with bilateral otitis externa. The remaining 12 of 32 isolates were recovered from 12 different patients with unilateral otitis externa. Eleven RAPD patterns (A,B,C,D,E,F,H,I,R,U,V) were associated with severe clinical symptoms, including severe pain, severe external auditory canal swelling, periauricular cellulitis, and a yellowish discharge. The remaining RAPD patterns were not associated with severe infections. This denotes a possible association between certain genotypes and severity of symptoms.

Median palatine cyst: an unusual presentation of a rare entity.

Median palatine cyst is rare. Mostly, it is asymptomatic and usually is discovered incidentally during routine dental or radiological examination. The case that we report has the following unusual features: Firstly, it is the largest cyst to be reported, measuring 5 cm in diameter. Secondly, there was no swelling on the oral surface of the hard palate contrary to other reports. Rather, it caused elevation of the nasal floor and nasal obstruction. Thirdly, it pushed the inferior and caudal end of the septum into the left nasal chamber. The median palatine cyst was surgically removed by a sublabial degloving approach. The cyst was removed in toto and the palatal bone curetted to ensure adequate removal of any nesting cells that could lead to recurrence in the future.

PCR-based detection, restriction endonuclease analysis, and transcription of tonB in Haemophilus influenzae and Haemophilus parainfluenzae isolates obtained from children undergoing tonsillectomy and adenoidectomy.

We developed and evaluated a PCR-based-restriction endonuclease analysis method to detect and analyze the tonB gene of Haemophilus influenzae and Haemophilus parainfluenzae from pediatric patients undergoing tonsillectomy and adenoidectomy. Multiple sites from the same patient, including the surface of adenoids and tonsils, as well as the core of tonsils, were cultured on chocolate agar and identified using standard procedures and the API NH Kit. A total of 55 H. influenzae isolates were recovered from different sites of 20 patients, and 32 H. parainfluenzae isolates were recovered from various sites of 12 patients. DNA was extracted from American Type Culture Collection strains and test isolates by the PureGene kit. Two primers, G1 (21-mer) and G2 (23-mer), were designed by us to amplify by PCR the tonB gene that consists of an 813-bp fragment. A nested PCR using primers T1 (23-mer) and T2 (24-mer) that flank an internal sequence to the gene of the order of 257 bp and restriction endonuclease digestion using XhoI and BglII were done to detect whether heterogeneity within the gene exists between the two species. Reverse transcription-PCR (RT-PCR) was finally done to detect transcription of the gene in both species. Our data have shown that the tonB gene was detected in both species. It is known to encode a virulent protein, TonB, in H. influenzae; however, demonstration of its presence in H. parainfluenzae is novel. Nested-PCR and restriction endonuclease analysis have shown that the tonB gene is apparently structurally the same in both species, with possible differences that may exist in certain H. parainfluenzae isolates. RT-PCR done on selected numbers of H. influenzae and H. parainfluenzae have shown that the tonB gene was transcribed in both species. This shows that the TonB protein, if expressed, may play a different role in the virulence in H. parainfluenzae since it is not needed for heme or heme complexes uptake as with H. influenzae.

Endoscopic removal of an ectopic third molar obstructing the osteomeatal complex.

We report a rare case of an ectopic third molar at the level of the osteomeatal complex. A 21-year-old man came to us with a left-sided nasal obstruction of 2 years' duration. Computed tomography of the paranasal sinuses revealed that an aberrant tooth was obstructing the osteomeatal complex and bulging into the ethmoid infundibulum. Opacity of the entire left maxillary sinus indicated the presence of an associated cystic formation. A transnasal endoscopic sinus technique was employed to create a large middle meatal antrostomy and to remove the tooth as well as the cystic contents and cyst wall. Pathologic analysis revealed that the cyst was dentigerous. After recovery from surgery, the patient resumed nasal breathing. The endoscopic surgical approach used in this case caused less morbidity than do the more common methods (e.g., the Caldwell-Luc procedure) of removing ectopic teeth from the sinus.

Post-adenoidectomy inflammatory pseudotumor.

PROBLEM: Inflammatory pseudotumor is a rare pathology in the head and neck area. Multiple post-adenoidectomy complications have been described in the literature without alluding to such an entity. METHOD: A case report of an inflammatory pseudotumor following an adenoidectomy. MAIN RESULTS: Pseudotumor of the nasopharynx should be added to the list of possible complications of adenoidectomy. CONCLUSION: Inflammatory pseudotumor of the nasopharynx is a rare complication that confronts the otolaryngologist and the pathologist with a diagnostic challenge. Surgical excision remains the best therapeutic option.

Squamous cell carcinoma of the lower lid in a 19-month-old girl with xeroderma pigmentosum.

Squamous cell carcinoma (SCC) of the skin usually occurs in older patients and commonly develops from actinic keratosis. Patients with xeroderma pigmentosum (XP) can acquire SCC at an early age. To our knowledge the youngest reported patient with XP and SCC was 8 years of age. We report a 19-month-old Lebanese girl with XP who presented clinically because of a rapidly growing mass of the medial part of her right lower lid that was biopsied and found to be squamous cell carcinoma. The mass was surgically excised with no evidence of recurrence after 2 years of follow-up. We describe our clinical experiences with this patient and have reviewed the available literature concerning XP and malignancy.

Two-step PCR-based assay for identification of bacterial etiology of otitis media with effusion in infected Lebanese children.

We developed and evaluated a two-step PCR-based assay with universal primers and genus- or species-specific primers for the detection of the most prevalent bacterial etiologies of otitis media with effusion (OME) in children from Lebanese hospitals. These etiologies included Haemophilus, Streptococcus, and Moraxella (Branhamella) catarrhalis, which were detected in middle-ear effusion (MEE) samples taken from children with OME. A total of 47 MEE samples were aspirated from 36 patients during insertion of a tympanostomy tube performed particularly for OME. The duration of effusion in all patients was > or =2 months. DNA was extracted from MEE samples, and PCR was initially done with DNA extracts by using the universal primers RW01 and DG74, which flank an approximately 370-bp fragment found in the 16S rRNA gene of all bacterial species. For the identification of specific bacteria, we used in three separate reaction mixtures the following genus- or species-specific primers: (i) a Haemophilus-specific probe (probe RDR125) as a primer along with DG74, (ii) a Streptococcus-specific primer (primer STR1; designed by us) along with DG74, and (iii) an M. catarrhalis-specific primer pair (primer pair MCA1-MCA2). Thirty-five MEE samples (74.5%) gave the expected 370-bp band, indicating the presence of bacterial DNA in the tested samples. Of the 35 PCR-positive samples tested, 33 (94.3%) were positive for Haemophilus, 3 (8.6%) were positive for Streptococcus, and 10 (28.6%) were positive for M. catarrhalis. Ten samples (28.6%) exhibited a mixed infection and were positive for both Haemophilus and M. catarrhalis. Culture was simultaneously performed for all 47 MEE samples. Ten of the 47 MEE samples (21.3%) exhibited bacterial growth. These 10 were PCR positive for bacterial DNA. The remaining 25 PCR-positive samples were negative by culture, thus showing about 53% discordance between PCR results and those of culture. The PCR assay proved to be more sensitive than culture, more rapid, less cumbersome, and more cost-effective than the available PCR-Southern hybridization-based assays.

Bacterial etiology of otitis media with effusion in a group of Lebanese children.

Identification of the main bacteria causing otitis media with effusion (OME) in a given population is essential. It indicates the degree of involvement of a given bacterium in a particular disease of that population. Knowledge of the most prevalent bacteria would initiate the search for the mode of acquisition of such bacteria and may aid in establishing appropriate control and prevention programs, which may decrease the incidence of OME. The rapid response of most OME to a variety of broad-spectrum antimicrobials deprives the clinician from knowing the particular bacteriologic agent prevailing in a community. With the emergence of resistant strains and the change over time of the relative distribution of bacteriologic agents known to cause OME, the identification of the bacterial etiology of OME in Lebanese children was initiated.

The etiologic role of the osteo-meatal complex in the pathogenesis of sinusitis: a retrospective study of clinical, CT and endoscopic findings in 143 patients.

UNLABELLED: The etiological role of the osteo-meatal complex (OMC) in the pathogenesis of sinus disease is a debatable issue. The charts of 143 patients who underwent endoscopic sinus surgery at the American University of Beirut Medical Center between 1992 and 1995 were reviewed. Clinical symptoms included facial pain, nasal obstruction, headache, and postnasal drip. CT scan and endoscopic findings were reviewed. The presence of OMC disease radiologically was correlated with all the clinical, nasal endoscopic and other radiologic findings (disease in the rest of paranasal sinuses, or presence of concha bullosa). Its etiological role in patients with sinusitis is discussed. RESULTS: No endoscopic findings could be statistically correlated with the OMC disease. Facial pain and postnasal drip were the only clinical symptoms that statistically correlated with the OMC disease (p-value = 0.009 and 0.008, respectively). The OMC disease correlated with the radiological evidence of sinusitis in any of the sinuses.
