Endoscopic view and MRI of a Thornwaldt's cyst of the nasopharynx.

A Thornwaldt's cyst is an uncommon nasopharyngeal lesion that develops from the remnant of the primitive notochord. A 65-year-old man with a Thornwaldt's cyst is presented in this case report. The patient was diagnosed by rigid nasal endoscopy and magnetic resonance imaging (MRI). These cases are infrequently presented in the English journals. Our study suggested that endoscopic and MRI examinations of the nasopharynx were a simple, rapid, and useful procedure for the diagnosis of the Thornwaldt's cysts.

Necrotizing pneumonia in children.

AIM: Clinical features and outcome of 36 patients with necrotizing pneumonia (NP) as well as 36 children with parapneumonic effusions (PPE) and 36 with severe control pneumonia (CP) were investigated. The mean age of the patients in the NP, PPE and CP groups were similar (3.8 +/- 3.3 (mean +/- SD), 4.2 +/- 3.0 and 4.2 +/- 3.0 y, respectively (p > 0.05)). The duration of symptoms at presentation were 11.9 +/- 8.5, 9.2 +/- 7.2 and 6 +/- 3.6 d, respectively (p < 0.01). The diagnosis of NP was established by computerized tomography. The mean (mean +/- SD) laboratory results in patients with NP revealed a white blood cell (WBC) count of 19,300 +/- 8700/mm3, erythrocyte sedimentation rate (ESR) of 71 +/- 22 mm/h, C-reactive protein (CRP) of 13.6 +/- 11.7 mg/dl and aspartate aminotransferase (AST) of 66 +/- 132 U/L. The values of WBC, ESR, CRP and AST in the NP group were significantly higher than those of the other groups (p < 0.001). The duration of hospitalization in the NP, PPE and CP groups was 26 +/- 9, 16 +/- 6 and 10 +/- 5 d, respectively (p < 0.001). The number of febrile days was 8 +/- 4, 4 +/- 3 and 3 +/- 3 (p < 0.001), and the duration of normalization of CRP was 14 +/- 4, 11 +/- 4 and 7 +/- 3 d (p < 0.001), respectively. The average cost of treatment was 3476 US dollars, 1646 US dollars and 844 US dollars, respectively (p < 0.001). CONCLUSION: All NP patients except two (94%) were complicated with PPE. The effusion in patients with NP and PPE was complicated with bronchopleural fistula (55% and 0%, respectively, p < 0.001). Surgical treatment was required in 66%, 8% and 0% in patients with NP, PPE and CP, respectively (p < 0.001). The mortality rate was 5.5%, 2.7% and 0% (p > 0.05).

Slime factor positivity in coagulase negative staphylococci isolated from nasal samples of haemodialysis patients.

Polysaccharide slime seems to be the most important factor by which coagulase negative staphylococci (CNS) strains adheres and colonises catheters. The aim of this study was to determine the prevalence of slime-producing CNS strains isolated from nasal samples of patients on haemodialysis and of healthy persons as a control. Nasal cultures were performed for 131 haemodialysis patients and 56 healthy persons. CNS strains were isolated from 86 of 131 patients (72.9%), and 46 of 56 healthy persons (82.1%). Twenty-four (27.9%) of the 86 CNS strains tested in the patient group and four (8.7%) of the 46 CNS strains in the control group were slime factor positive. There was a significant difference (p<0.01) in slime production between CNS strains isolated from haemodialysis patients and from control group. The detection of slime-producing coagulase-negative staphylococcus carriage in haemodialysis patients may prevent dialysis catheter-related coagulase-negative staphylococcal infections.

The progression of maternal RSV antibodies in the offspring.

The concentrations of maternal anti-RSV IgG antibodies were followed in 49 healthy newborns over the first six months of life. At birth, 41 mothers (83%) tested positive for anti-RSV IgG and all of their babies carried maternal anti-RSV IgG. Anti-RSV IgG positivity dropped to 73% at 1 month, 6% at 3 months, and 2% at 6 months. Between 3 and 6 months, 8% did acquire RSV infection, half of them as acute bronchiolitis and half as non-specific respiratory infection. All of the patients who acquired clinical RSV disease had an antibody concentration of <20 RU/ml which may be the cut off value for protection.

Reliability of procalcitonin as a severity marker in critically ill patients with inflammatory response.

Procalcitonin (PCT) is increasingly recognised as an important diagnostic parameter in clinical evaluation of the critically ill. This prospective study was designed to investigate PCT as a diagnostic marker of infection in critically ill patients with sepsis. Eighty-five adult ICU patients were studied. Four groups were defined on the basis of clinical, laboratory and bacteriologic findings as systemic inflammatory response syndrome (SIRS) (n = 10), sepsis (n = 16), severe sepsis (n = 18) and septic shock (n = 41). Data were collected including C-reactive protein (CRP), PCT levels and Sequential Organ Failure Assessment and Acute Physiology and Chronic Health Evaluation II scores on each ICU day. PCT levels were significantly higher in patients with severe sepsis and septic shock (19.25 +/- 43.08 and 37.15 +/- 61.39 ng/ml) than patients with SIRS (0.73 +/- 1.37 ng/ml) (P < 0.05 for each comparison). As compared with SIRS patients, plasma PCT levels were significantly higher in infected patients (21.9 +/- 47.8 ng/ml), regardless of the degree of sepsis (P < 0.001). PCT showed a higher sensitivity (73% versus 35%) and specificity (83% versus 42%) compared to CRP in identifying infection as a cause of the inflammatory response. Best cut-off levels were 1.31 ng/ml for PCT and 13.9 mg/dl for CRP. We suggest that PCT is a more reliable marker than CRP in defining infection as a cause of systemic inflammatory response.

Meropenem in neonatal severe infections due to multiresistant gram-negative bacteria.

Recently, new broad spectrum carbapenem has been investigated on a world-wide scale for the treatment of moderate to severe infections. In the neonatal intensive care units the extensive use of third generation cephalosporins for therapy of neonatal sepsis may lead to rapid emergence of multiresistant gram-negative organisms. We report the use of meropenem in 35 infants with severe infections due to Acinetobacter baumanii and Klebsiella pneumoniae. All gram negative bacteria were resistant to ampicillin, amoxicillin, ticarcilin, cefazoline, cefotaxime, ceftazidime, ceftriaxone and aminoglycosides. Eighty two percent of the cases (29/35) were born prematurely. Assisted ventilation was needed in 85.7% (30/35). All infants deteriorated during their conventional treatment and were changed to meropenem monotherapy. Six percent (2/35) died. The incidence of drug-related adverse events (mostly a slight increase in liver enzymes) was 8.5%. No adverse effects such as diarrhea, vomiting, rash, glossitis, oral or diaper area moniliasis, thrombocytosis, thrombocytopenia, eosinophilia and seizures were observed. At the end of therapy, overall satisfactory clinical and bacterial response was obtained in 33/35 (94.3%) of the newborns treated with meropenem. Clinical and bacterial response rates for meropenem were 100% for sepsis and 87.5% for nosocomial pneumonia. This report suggests that meropenem may be a useful antimicrobial agent in neonatal infections caused by multiresistant gram negative bacilli. Further studies are needed to confirm these results: Meropenem, newborn, sepsis and nosocomial infection.

Amyopathic dermatomyositis associated with cervical cancer.

We here report a 44-year-old female patient who is the first documented case of cervical carcinoma with amyopathic dermatomysitis (ADM). The association of ADM with malignancy is clearly stated in the literature. This patient first presented with classic cutaneous findings of dermatomyositis with no signs and symptoms of muscle involvement for the first 7 months following the diagnosis. When this case has been worked up for malignancy by invasive procedures such as cervical cone biopsy, an increase in muscle enzymes and exacerbation of skin findings were detected.

Color Doppler ultrasonography in ocular Behçet's disease.

PURPOSE: The aim of this prospective study was to assess the ocular hemodynamic changes in patients with Behcet's disease who had involvement of the posterior segment by color Doppler ultrasonography. METHODS: The present study was carried out in 32 eyes of 24 patients with ocular Behcet's disease and 42 eyes of 21 persons as a healthy age-matched control group. In order to detect the hemodynamic changes in ocular Behcet's disease, peak systolic and end-diastolic velocities (PSV, EDV; cm/sec), resistive and pulsatile indices (RI, PI), and PSV/EDV ratio of central retinal artery (CRA), short posterior ciliary artery (PCA) and ophthalmic artery (OA) were determined. RESULTS: The mean PSV and EDV (8.1+/-2.6 and 2.7+/-0.1 cm/sec, respectively) in the CRA were significantly lower in patients with Behcet's disease than in healthy controls (11.5+/-2.2 and 3.5+/-1.0 cm/sec, respectively, p<0.001). For the PCA, these values (12.7+/-4.2 and 4.3+/-1.1 cm/sec, respectively) were significantly lower in the patient group than in the control the group (18.2+/-4.2 and 6.1+/-2.5 cm/sec, respectively, p<0.001). In the patient group, a statistically significant decrease compared to the control group was detected in the mean PSV of the OA (31.8+/-8.2 and 35.8+/-0.6 cm/sec, respectively, p<0.02). However, no significant difference in the other parameters of these vessels was observed between groups. CONCLUSIONS: These results demonstrate the presence of some circulatory changes in the flow velocities of the CRA, PCA and OA in patients with Behcet's disease when compared with control subjects.

Effect of Octreotide on experimental corneal neovascularization.

PURPOSE: To examine the ability of subcutaneously administered Octreotide ( a long acting somatostatin analoque) to serve as an inhibitory agent for corneal neovascularization in eyes of Wistar Albino rats. METHODS: Neovascular growth into the corneas of all the animals was induced by silver nitrate cauterization. Half of the animals which were randomly selected for the Octreotide group received 30 micrograms systemic Octreotide for 7 days. The treatment was initiated on the same day as chemical cauterization. The rest of the animals (control group) received no treatment. Slit lamp and histopathologic examination of the corneas of both groups were performed at the end of the study period. RESULTS: It was observed that the corneal neovascularization and histopatologic scores of the Octreotide group were significantly lower than those of the control group (p < 0.001, p < 0.01). CONCLUSION: Systemic administration of Octreotide inhibits the corneal neovascular response in a rat model.

The comparison of cyclopentolate and atropine in patients with refractive accommodative esotropia by means of retinoscopy, autorefractometry and biometric lens thickness.

PURPOSE: In this study, we aimed to compare the cycloplegic effect of cyclopentolate HCI 1% and atropine sulphate 1% in patients with refractive accommodative esotropia by means of retinoscopy, autorefractometer and the measurement of lens thickness by biometry. METHODS: Thirty-two patients with refractive accommodative esotropia aged from 5 to 10 (mean 6.8+/-1.4), had a deviation under 10 prism diopters, and underwent retinoscopic, autorefractometric and biometric study in dry and wet conditions. RESULTS: The retinoscopic, autorefractometric and biometric findings of the right eye were 5.10+/-1.21 diopter (D), 5.03+/-1.20 D, 3.43+/-0.16 mm with cyclopentolate, and 5.2+/-1.2 D, 5.2+/-1.2 D, 3.4+/-0.1 mm with atropine. In the left eye, the measurements were 5.2+/-1.4 D, 5.1+/-1.4 D, 3.5+/-0.2 mm with cyclopentolate, and 5.3+/-1.2 D, 5.20+/-1.3 D, 3.4+/-0.2 mm with atropine, respectively. When these obtained data were compared by the Student's t test no statistical significance was found (p > 0.05). CONCLUSIONS: We suggest that the cyclopentolate cycloplegia applied to the patients with refractive accommodative esotropia is sufficient to produce good cycloplegia, with an effect similar to atropine.

Penetration of oral and topical ciprofloxacin into human aqueous humor.

PURPOSE: This study was planned to investigate the penetration of ciprofloxacin into aqueous humor following oral and topical application as a prophylactic antimicrobial agent. METHODS: Forty-six patients undergoing cataract surgery were randomly divided into two groups. In the first group, the patients received 500 mg oral ciprofloxacin eight hours before surgery and in the second, 5 drops of 0.3% ciprofloxacin were applied to the patients every twenty minutes, starting 100 minutes before the surgery. By paracentesis, aqueous samples were taken just before the operation so the interval between the first topical application and paracentesis was 100 minutes. RESULTS: The mean concentration of ciprofloxacin in aqueous humor was 0.63+/-0.29 microg/ml in the first group. The concentration was 0.69+/-0.30 microg/ml in the second group. Both of these mean concentrations were higher than the levels of MIC90 of S.aureus , S. epidermidis, P. aeruginosa and Gram (-) bacteriae. CONCLUSION: As a result, both topically and orally applied ciprofloxacin achieved a significant aqueous concentration. Each route studied might be suitable for surgical prophylaxis or treatment of infections.

Anthrax as the cause of preseptal cellulitis.

Anthrax is an infectious disease caused by Bacillus anthracis. It is primarily a disease of domestic animals such as cattle, goats, and sheep; but humans can rarely be infected by contact with infected animals or contaminated animal products. Our case is a 4-year-old boy who was initially diagnosed as preseptal cellulitis, but later he showed the characteristic anthrax lesions with a black necrotic eschar. Scrapings from the necrotic tissue showed gram positive rods and culture grew Bacillus anthracis. The patient responded to intravenous administration of penicillin G, and the lesions resolved, leaving a scar on the right upper eyelid. Eyelid involvement of anthrax is rarely seen in clinical practice, but should be considered in differential diagnosis.

Effect of topical apraclonidine on flow properties of central retinal and ophthalmic arteries.

To investigate the acute effects of topically administered 1% apraclonidine hydrochloride on blood velocity and resistance parameters of central retinal and ophthalmic arteries, the vessels were studied by color Doppler ultrasonography during baseline and at the time of peak effect of apraclonidine in 20 healthy volunteers. After medication, significant decrease in peak systolic, peak diastolic, mean flow velocities and increase in resistive and pulsatility indices of ophthalmic artery were observed. Blood velocity and resistance parameters of central retinal artery didn't change significantly. In conclusion, topically used apraclonidine was thought to change the blood velocity and resistance parameters of ophthalmic artery as a result of its local vasoconstrictory effect on the anterior segment branches of ophthalmic artery.

Low dose cyclosporin A treatment in generalized pustular psoriasis.

Generalized pustular psoriasis is a rare form of psoriasis, seldom seen in children. Three patients with generalized pustular psoriasis are presented, two of whom were a sister and brother and whose grandfather also had pustular psoriasis. Lesions consisted of pustular, erythematous, scaly, follicular papules located on the trunk, scalp, and extremities. The pustules in some areas coalesced to form lakes. Histologic examination of several biopsy specimens revealed the changes of pustular psoriasis, which were parakeratosis, elongation of the rete ridges, and deep spongioform pustules and Munro abscesses. All patients were treated with cyclosporin A for periods of 2-12 months. The doses ranged from 1 to 2 mg/kg/day. Clearance of psoriatic lesions occurred after 2-4 weeks of therapy.

The role of pre-operative B mode ultrasound in the evaluation of the axillary lymph node metastases in the initial staging of breast carcinoma.

The lymph node status of a breast cancer is one of the main prognostic criterias. This status is very important to determine the therapeutic approach. Physical examination alone is not sufficient to assess axillary metastases. Mammographic examination can give us an idea about breast cancer and axillary involvement. Ultrasonographic evaluation can improve the sensitivity of clinical and mammographic examination in assessing axillary lymph node status. 42 patients operated on for breast cancer between January 2000-January 2003 were included in this prospective study. In the study, we used axillary B mode ultrasound to evaluate the axillary lymph nodes. There are several sonographic features to categorize them. Axillary B mode ultrasound was performed to evaluate the axillary lymph nodes for metastatic involvement. In the evaluation of lymph nodes, the sonographic criteria were centric echogenity, thickening of cortex, length/width ratio (L/W) and the diameter of lymph nodes. Hyperechogenic hilus was accepted as a benign finding. The thickening of the cortex less than 50% of the thickening of the centric echogenic hilus was also accepted as a benign finding. L/W ratio below 2 and parameters above 2 cm were accepted as malignant findings. 168 lymph nodes in 42 patients were evaluated pre-operatively with axillary B mode ultrasound. As a result, these lymph nodes were defined as benign in 19 patients (45.2%) and malignant in 23 patients (54.8%). Axillary lymph node status was found as benign in 18 patients (42.9%) and malignant in 24 patients (57.1%) pathologically . Comparative results of ultrasound and axillary lymph node status can be seen on Table III. As a result, the sensitivity of axillary B mode ultrasound to show the metastases was found as 79.1%, specificity was 77.7%, positive predictive value 82.6% and negative predictive value 73.6%. We think some better results may be obtained in the future and these developments may affect the surgeon's decisions concerning axillary dissection for breast cancer operations.
