RESUMO

AIMS: To evaluate the presence of dentofacial asymmetry in patients with odontoma by panoramic radiography. METHODS: Panoramic images with odontoma were selected among all panoramic radiographs (3058 patients). Maxillary odontoma was detected in 27 patients while mandibular odontoma was detected in 25 patients. In addition, 30 patients with similar age and gender characteristics were selected as the control group. Skeletal angular, skeletal linear and dental measurements were performed on panoramic radiographs. The odontoma region and the opposite side of the odontoma of the individuals were examined. The dentofacial asymmetry of the odontoma groups was compared with the control group. Paired t-test was used to determine dentofacial asymmetry on the right and left side of the patients with odontoma. The ANOVA test was used for testing the differences among groups. RESULTS: As a result of study, no significant difference was found between the region of the odontoma and the symmetrical region in the maxilla and mandibula (P > 0.05). In the control group, a statistically significant difference was found in the angle between the mandibular canal and the mental foramen, lower incisor size, PFH/CutCat(°), and Co-Mc-Me(°) measurements (P < 0.05). In the maxillary and mandibular odontoma groups, a statistically significant difference was found in the angle between the mandibular canal and the menton, CH (mm), RH (mm), and CrH (mm) in the comparison of the odontoma and the control group (P < 0.05). CONCLUSIONS: No difference was found between the right and left sides of the jaws related with the asymmetry of the maxilla and mandible.

RESUMO

BACKGROUND: Acetaldehyde has been implicated as a major factor in oral carcinogenesis associated with alcohol consumption. In this study, saliva samples from oral cancer patients and healthy individuals were incubated in vitro with ethanol in order to investigate factors which can influence salivary acetaldehyde production. MATERIALS AND METHODS: A total of 66 individuals (40 males and 26 females, mean age 52 years) participated in the study. Participants were classified into three groups: Group 1 (oral cancer patients [n = 20]); Group 2 (poor dental health status [n = 25]) and Group 3 (good dental health status [n=21]). Every patient chewed a 1g piece of paraffin chewing gum for 1 minute then saliva samples were collected from all individuals. After in vitro incubation of the samples with ethanol, the levels of salivary acetaldehyde production was measured by head space gas chromatography. Kruskal-Wallis and Mann-Whitney tests and Spearman's Correlations analysis were performed for statistical analyses. RESULTS: The salivary acetaldehyde production was significantly higher (p <0.0001) in both group 1 and group 2 when compared to group 3. However, there was no significant difference between group 1 and group 2. Poor dental health status, infrequent oral hygiene habits and dental visits, smoking and presence of a dental prosthesis were significant parameters for increased levels of salivary acetaldehyde production from alcohol. The evaluation of salivary acetaldehyde production after in vitro incubation with ethanol may be useful for early detection of oral cancer. CONCLUSION: According to the results of this study, the significantly higher levels of salivary acetaldehyde production in oral cancer patients and individuals with poor dental health status may suggest a possible link between increased salivary acetaldehyde production and oral cancer. Improved oral hygiene can effectively decrease the level of salivary acetaldehyde production in oral cavity. Hippokratia 2014; 18 (3): 269-274.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the frequency of micronuclei (MNs) in both circulating lymphocytes and buccal epithelial cells of patients with oral lichenoid contact reactions (OLCRs) or with oral lichen planus (OLP) and compare their MN scores with those of healthy controls (HCs). MATERIAL AND METHODS: The study group included 21 patients (mean age 51.3 ± 12.4; 6 males, 15 females) with OLCRs and 22 patients (mean age 47.6 ± 14.4; 4 males, 18 females) with OLP who were clinically diagnosed and histopathologically confirmed according to WHO diagnostic criteria (WHO Collaborating Centre for Oral Precancerous Lesions, 1978). All patients with OLCR demonstrated contact allergy to tested dental materials when evaluated by skin patch testing according to International Contact Dermatitis Research Group (ICDRG), while all OLP patients tested negative to patch testing. Seventeen individuals with no oral mucosal disorders (mean age 51.7 ± 11.3; 8 males, 9 females) were recruited to constitute the healthy control group. [Correction added on 30 May 2014, after first online publication: the term, 'mean age' has been added to the text in parenthesis throughout the Material and Methods section.] Clinical features including type of OLP, location, disease severity, presence of skin lesions, presence of systemic disease including any allergies and dental (periodontal) status were recorded. MN analyses were performed on peripheral blood lymphocytes and on smears of buccal epithelial cells of all three study groups. RESULTS: Most OLP and OLCR lesions were of reticular type (83%), and OLP lesions were distributed bilaterally on the buccal mucosa (90.5%). The medians of MN frequencies in buccal epithelial cells in OLP and OLCR groups were significantly higher when compared with HC group (P < 0.001). [Correction added on 30 May 2014, after first online publication: in the results, 2nd sentence, the word 'lymphocytes' has been removed.] There was no significant difference between OLP group (14.5 range 3-95) and OLCR group (16.0 range 3-93) in terms of median MN frequencies in buccal epithelial cells (P = 0.724) nor in peripheral lymphocytes between OLP group (2.0 range 0-7) and OLCR group (1.0 range 0-6) (P = 0.92). [Correction added on 30 May 2014, after first online publication: (P = 0.92) was wrongly placed after 'peripheral lymphocytes' and has now been shifted to the end of the last sentence.] CONCLUSIONS: Micronuclei scores do not distinguish OLP from OLCR when using buccal smears. OLP and OLCR both demonstrated significantly higher MN frequencies in buccal cells, compared with healthy controls. MN assessment in both buccal epithelial cells and circulating lymphocytes may serve as a potential biomarker tool for evaluating any cancer risk in OLP and OLCR. [Correction added on 30 May 2014, after first online publication: the first and second sentences in the conclusions have been slightly changed.].

RESUMO

OBJECTIVE: While isolated hepatosteatosis is a benign disease, in minority of cases non-alcoholic steatohepatitis (NASH) may even lead to cirrhosis in long-term. In order to find the stage of the disease and determine the prognosis, a liver biopsy is indicated. In this study, we studied the relationship of liver histopathological findings with serum levels of hepatic enzymes. METHODS: We recruited 52 cases of NASH with Type 2 diabetes mellitus. Diagnosis of NASH was made based on biochemical tests, ultrasound images and liver biopsy. RESULTS: Steatosis was mild in 57.7%, moderate in 30.8%, and severe in 11.6% of patients. While no infiltration was found in 78.8% of cases, there was a grade-1 infiltration in 15.4% and a grade-2 infiltration in 5.8% of cases. Similarly, no fibrosis was found in 42.3% of patients, but there was a stage-1 fibrosis in 50%, and a stage-2 fibrosis in 7.7% of cases. In patients with severe steatosis, serum levels of AST were higher than mild or moderate stage steatosis. Accordingly, in patients with no inflammation, serum levels of ALT were higher than in patients with inflammation. However, in patients with fibrosis, triglycerides levels were significantly lower and ALP was significantly higher than in patients without fibrosis. The correlation analysis indicated a positive association between serum levels of ALP and C-peptide. CONCLUSION: In addition to conventional risk factors such as age, presence of diabetes, female sex; higher levels of ALP may be considered as a risk factor linked to hepatic fibrosis in patients with NASH and type 2 diabetes (Tab. 6, Ref. 8).

RESUMO

BACKGROUND: We aimed to investigate the protective potential of the thoracic cage on the parenchyma in response to blunt trauma from different directions in an animal model. METHODS: Female Wistar albino rats were divided into control, anterolateral, lateral and posterolateral trauma groups, with six rats in each group. A weight of 500 g was dropped from a height of 40 cm on the left hemithorax to produce an energy of 1.96 joules, using a specially designed platform. Respiratory rates and heart rates were noted before and at 0, 1, and 5 minutes after trauma. Twenty-four hours later, the left lungs were excised for wet lung weight measurement, histological examinations and tissue malondialdehyde determination. RESULTS: Severe pulmonary contusion was observed in all trauma groups according to histological parameters. Malondialdehyde was increased in both the lateral and posterolateral groups. Wet lung weight was increased only in the posterolateral trauma group when compared to controls. Histologically, macrophages were increased and mononuclear cell infiltration was significant in the posterolateral trauma group. There were no significant changes in physiological parameters in the groups. CONCLUSION: Lung parenchyma seems to be badly affected after trauma to the posterolateral thoracic wall. Different thoracic regions may respond differently to the same traumatic stress, and this may be related to the biomechanical properties of the thoracic cage.

RESUMO

AIM: To investigate histopathological changes in ureteropelvic junction obstruction (UPJO) from an etiological perspective. PATIENTS AND METHODS: Medical records of patients with UPJO were reviewed and pathological specimens collected. Nephrectomy materials from forensic autopsies were taken as controls. Specimens were assessed with light microscopy. Fibronectin, type 4 collagen, laminin, Bax and Bcl-2 expression for apoptosis, together with interstitial cells of Cajal determination with c-kit were determined immunohistochemically. Staining scores were evaluated semiquantitatively. Results were evaluated using Mann-Whitney U-test. RESULTS: Control group comprised 14 children (median age, 3.5 years; 6 months-17 years). Study group comprised 22 children with UPJO (median age, 9 months; 1 month-10 years). Light microscopy revealed non-specific inflammation, epithelial proliferation and atrophy with fibrosis in the smooth muscle of the UPJ in all patients. Fibronectin, type 4 collagen and laminin were found to be significantly increased in UPJO at the intrafascicular space of smooth muscle and the matrix of stroma. Bcl-2 expression was increased in UPJO. c-Kit was unable to stain interstitial cells of Cajal, but staining for mast cells was significant. CONCLUSIONS: High expression of fibronectin, laminin and type 4 collagen may indicate a relation to the pathogenesis of UPJO. Defective kidney morphogenesis, during branching and tubulogenesis of ureteric bud, may be responsible for this congenital pathology.

RESUMO

The goal of the present study was to investigate the effects of ovariectomy and naproxen treatment on both femoral and mandibular bone mass and biomechanical competence. Sprague-Dawley rats were used and divided into five groups: baseline, sham ovariectomized, ovariectomized, sham ovariectomized + naproxen treatment, ovariectomized + naproxen treatment. Mandibles and femurs of the rats were extracted and bone mineral density of the extracted specimens were determined. The volumes and ash weights of the femurs and mandibles were estimated. Maximum loads of the femurs and mandibles were determined by using a three point bending test. Ovariectomy decreased bone mineral density of the femoral midshaft, however naproxen prevented this decrease. Neither ovariectomy nor naproxen treatment affected the BMD in the molar alveolar region. Maximum load was found significantly decreased in the femoral midshaft, however, naproxen treatment prevented this decrease. Maximum load of the molar alveolar region did not significantly change. Naproxen prevents the strength characteristics of femoral midshaft afforded by ovariectomy. However, neither ovariectomy nor naproxen has an effect on the molar alveolar region of the mandible.


El objetivo del presente estudio fue investigar los efectos de la ovariectomía y el tratamiento con naproxeno sobre la masa y la competencia biomecánica del fémur y hueso mandibular. Fueron utilizadas ratas Sprague-Dawley, la que se dividieron en cinco grupos: referencia, ovariectomizadas simuladas, ovariectomizadas, ovariectomizadas simuladas + tratamiento naproxeno, ovariectomizadas + tratamiento naproxeno. Las mandíbulas y los fémures de las ratas fueron extraídos y se determinó la densidad mineral ósea (DMO) de las muestras extraídas. Los volúmenes y pesos de la ceniza fueron estimados. Las cargas máximas de las mandíbulas y fémures se determinaron utilizando un ensayo de flexión de tres puntos. La ovariectomía disminuyó la densidad mineral ósea de la diáfisis media del fémur; sin embargo, el naproxeno impidió esta disminución. Ninguna ovariectomía sin tratamiento de naproxeno afectó a la DMO en la región alveolar molar. La carga máxima se encontró significativamente disminuida en las diáfisis femoral media, pero por el tratamiento de naproxeno no se produjo esta disminución. La carga máxima de la región alveolar molar no cambió en ninguna condición. El naproxeno previene los cambios de resistencia causados por la ovariectomía de la diáfisis media del fémur. Sin embargo, ni la ovariectomía ni el naproxeno tienen un efecto en la región alveolar molar de la mandíbula.

RESUMO

This study aims to identify, compare and analyse the knowledge and opinions of dentists regarding oral mucosal lesions and evaluate the differences between the attitudes of dentists by practice settings. 300 dentists were enrolled in the study. Three groups were formed. The first group included general dental practitioners working in private dental offices; the second group were dentists practising in dental polyclinics; the third group was composed of dentists employed at universities in Istanbul, working in departments except for the department of oral surgery and medicine. A 17-item self constructed questionnaire investigating demographic attributes, dental practice characteristics, oral mucosal lesions (OML) knowledge and respondents' opinions was completed and all questions were asked by the same author. 85% of the dentists admitted difficulties in diagnosing OML. 62% failed to update their knowledge from the literature, 93% did not undertake biopsies or consult other practitioners. Dentists practising at universities attempted to treat fewer patients with OML (p=0.0001). The results of this questionnaire conclude that most dentists experience difficulties in diagnosing some OML.

RESUMO

OBJECTIVE: The purpose of this study was to determine the genetic instability of peripheral blood lymphocytes from patients diagnosed with oral lichen planus (OLP) by investigation of frequencies of micronuclei (MN) and sister chromatid exchange (SCE). MATERIALS AND METHODS: A total of 22 newly diagnosed and untreated patients with OLP of same severity scores and twenty healthy controls participated in this study. They were all non-smokers with no previous history or family history of cancer. The periodontal status, flow rate and buffering capacity of whole mouth saliva were recorded. SCE and MN analyses were performed on peripheral blood lymphocytes of OLP patients and healthy controls. RESULTS: The frequencies of MN (50.00 +/- 22.36) and SCE (6.89 +/- 1.48) in OLP patients were found to be significantly elevated compared with that in normal individuals (25.20 +/- 9.52 and 5.93 +/- 1.31; z = 3.946, P = 0.0001; z = 2.346, P = 0.019). There were no significant differences in the MN frequency and SCE between the two subgroups with reticular or erosive types of OLP. CONCLUSION: These pilot data indicate an increased genomic instability in peripheral blood lymphocytes of a cohort of Turkish patients diagnosed with oral lichen planus as compared with that of healthy individuals. As patients with OLP may have an increased or potential risk for oral malignancy, these assays could be used in translational research to monitor beneficial effects of interventions and long-term prognosis.

RESUMO

Pouch colon anomaly and high anorectal malformation are well-defined rare anomalies. The association of pouch colon anomaly with rectal atresia has previously been defined in only one case. In this study, a 2-day-old baby is presented with pouch colon anomaly without fistula and with rectal atresia. As a second case in the literature, this pathologic condition has been treated through the abdominotransanal route by using a single-stage endorectal coloanal pull-through. Being uncommon and having an important therapeutic approach, this case has been evaluated as worth presenting.

RESUMO

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are chronic, progressive, systemic inflammatory rheumatic diseases that lead to serious disability. The objective of this study was to investigate the demographic and clinical characteristics of the patients with RA and AS who were treated in tertiary hospitals in Turkey and to analyze their current medical management. A total of 562 RA and 216 AS patients were evaluated. The mean age of RA patients was 52.1 +/- 12.6 years. The female to male ratio was 3.7:1. Of the RA patients, 72.2% had positive rheumatoid factor (RF), 62.9% had high C-reactive protein, and 75.2% had radiological erosion. The ratio of patients with Disease Activity Score (DAS) 28 >3.2 was 73.9% and of those with Health Assessment Questionnaire (HAQ) > or =1.5 was 20.9%. There was a statistically significant increase in RF positivity and HAQ scores in the group with higher DAS 28 score. Frequency of extraarticular manifestations was 22.4%. The ratio of the patients receiving disease modifying antirheumatic drugs (DMARD) was 93.1%, and 6.9% of the patients were using anti-tumor necrosis factor (TNF) blocking agents. In AS, the mean age of the patients was 38.1 +/- 10.6, and the female to male ratio was 1:2.5. The time elapsed between the first symptom and diagnosis was 4.3 years. The ratio of peripheral joint involvement was 29.4%. Major histocompatibility complex, class I, B 27 was investigated in 31.1% of patients and the rate of positivity was 91%. In 52.4% of the patients, Bath AS Disease Activity Index (BASDAI) was > or =4. The erythrocyte sedimentation rate, Bath AS Functional Index, and peripheral involvement were significantly higher in the group with BASDAI > or =4. Frequency of extraarticular involvement was 21.2% in AS patients. In the treatment schedule, 77.5% of AS patients were receiving sulphasalazine, 15% methotrexate, and 9.9% anti-TNF agents. Despite widespread use of DMARD, we observed high disease activity in more than half of the RA and AS patients. These results may be due to relatively insufficient usage of anti-TNF agents in our patients and therefore these results mostly reflect the traditional treatments. In conclusion, analysis of disease characteristics will inform us about the disease severity and activity in RA and AS patients and could help in selecting candidate patients for biological treatments.

RESUMO

Hepatic pseudocyst formation is a rare intra-abdominal complication of ventriculoperitoneal shunts. The presence of an intracranial tumor and a history of central nervous system infection are major risk factors for the development of this complication. Hepatic pseudocysts secondary to ventriculoperitoneal shunts can be classified as intra- and extra-axially growing cysts. On abdominal computed tomography images, extra-axially growing pseudocysts are typically surrounded by a fine annulus that shows continuity to hepatic parenchyma. For treatment of extra-axially growing hepatic pseudocysts, surgical unroofing of the cyst and repositioning of the catheter is an effective method if there is no shunt infection and/or dysfunction.

RESUMO

BACKGROUND/PURPOSE: Recent reports have focused on detorsion after ovarian torsion in the literature. The aim of the study was to investigate late term changes in both ovaries after delayed detorsion following ovarian torsion in rats. MATERIALS: Female, prepubertal, Wistar albino rats were divided into four groups (n = 6/group). The left ovaries were used for the study and the right ovaries were kept as the control. The groups were constituted as follows: Group 1: left ovarian fixation, bilateral oophorectomy 48 hours later; Group 2: left ovarian torsion and fixation, bilateral oophorectomy 48 hours later; Group 3: detorsion 48 hours after torsion and bilateral oophorectomy after another 48 hours; Group 4: detorsion 48 hours after torsion and bilateral oophorectomy after 21 days. The total injury score (TIS) was compiled histologically in a double-blind fashion. Congestion, edema, bleeding and polymorphonuclear lymphocyte infiltration were assessed for TIS. RESULTS: The TIS was found to be 8 points in Group 1; 38 in Group 2; 28 in Group 3 and 12 in Group 4, respectively. The TIS was based on results from the left ovaries in Group 1, whereas 31 points were attributable to the left ovaries and 7 to the right ovaries in Group 2. In Groups 3 and 4, TIS points were the same in both study and control ovaries. The difference between the left ovaries of Groups 1 and 2 and the left ovaries of Groups 2 and 4 was statistically significant (p < 0.05). CONCLUSION: Viable ovarian tissue can be detected even after 48 hours of torsion, which is a relatively long period of ischemia. Tissue injury decreases significantly after detorsion during late recovery. In view of previous case reports in the literature and the present findings, detorsion is recommended in children with ovarian torsion regardless of the ischemic period and/or macroscopic appearance.

RESUMO

PURPOSE: The aim of this study was to investigate the genotoxic effect on the peripheral blood lymphocytes potentially induced by Re-186 in paediatric age group undergoing radiosynovectomy for haemophilic synovitis, by using chromosomal aberration analysis (CA) and the micronuclei (MN) assay for detecting chromosomal aberrations, as well as the sister chromatid exchanges (SCE) technique for assessing DNA damage. METHODS: Cytogenetic analyses were evaluated in 20 boys (mean age: 13.8 +/- 2.7 years) before, and 2 and 90 days after radiosynovectomy from the peripheral lymphocytes of the patients. Joint retention and extra-articular spread of the radionuclides were evaluated by using quantitative gamma camera imaging. RESULTS: Imaging after radiosynovectomy revealed local lymph node visualization in 8 (40%) patients and hepatosplenic visualization in 3 (15%) patients due to extra-articular leakage of radioactive material. The mean frequency of chromosome aberrations (0.2 +/- 0.4/1000 cells) determined prior to the onset of therapy was not significantly increased in comparison with control values obtained 2 days (0.4 +/- 0.5/1000 cells) and 90 days (0.2 +/- 0.4/1000 cells) after therapy (P = 0.754 and P = 1.0). In the analysis of MN and SCE, when we compare the baseline levels, the mean MN and SCE frequencies were slightly higher in the control analyses performed 2 and 90 days after radiosynovectomy but there were no significant differences between baseline and control levels (chi(2) = 2.621, P = 0.270 and F = 0.573, P = 0.569, respectively). CONCLUSION: The major finding of this study with relatively small sample is that, radiosynovectomy with Re-186 does not seem to induce early genotoxic effects on the peripheral blood lymphocytes in paediatric age group.

Ectopic adrenocortical tissues (EAT) are rare pathologies in children. They are frequently encountered in the inguinal region incidentally during surgical procedures but they are also classically known to be located from diaphragm to pelvis. EAT were investigated during inguinal procedures including inguinal hernia, hydrocele, hydrocele of cord and undescended testis (UDT) in 1,069 patients, 159 girls, 910 boys, from April 1997 until April 2006. All these nodules were confirmed to be adrenocortical tissues after histopathological examinations. Statistical analysis was done with Fisher's exact test. EAT were noted on the plexus pampiniformis external to processus vaginalis of 22 male patients (1.73%) during inguinal explorations. This figure was 1.63% for inguinal explorations of inguinal hernia, hydrocele and hydrocele of cord and 5.1% for UDT. This difference was statistically significant (P<0.0001). There were no EAT detected during inguinal exploration of female patients. EAT are uncommon pathologies seen during inguinoscrotal explorations. Incidence of EAT is significantly increased with UDT. This increase may be explained with the embryological events that take place during adrenal and gonadal development. The relatively low observation of EAT in girls may be due to the localization of gonads and association of EAT with gonadal position. Adrenal rests in inguinal region may suggest an association with descent of gonads.

RESUMO

OBJECTIVE: Relocations after disasters are known to cause added distress in survivors. This study examined the effects of migration and other factors on psychological status of survivors 4 years after the two severe earthquakes in Turkey. METHOD: Five hundred and twenty-six adult survivors of the 1999 earthquakes currently living in Ankara were given self-report measures assessing traumatic stress, depression, earthquake experience and social support. RESULTS: The rates of current post-traumatic stress disorder (PTSD) and depression were 25% and 11%, respectively. Although both traumatic stress and depression factors were predicted by some demographic and trauma severity variables, relocation status predicted depression but not traumatic stress. CONCLUSION: The rates of psychological distress were higher than expected in a city considered to be safe in terms of earthquake risk. Relocation after the disaster may increase psychological distress by disrupting the social network.

RESUMO

A case of Horner syndrome diagnosed during the follow-up after major thoracic trauma is presented in this report. A 10-year-old boy was admitted to the emergency service with severe thoracic trauma with left clavicular and first rib fracture after a traffic accident. During the follow-up, myosis and ptosis were recognized in his left eye. Cranial tomography and neurological examination were all normal. The symptoms were thought to be caused by compression of the local hematoma to the cervical ganglia. After 30 days of conservative treatment with tube thoracostomies, he was discharged with his Horner syndrome. After 6 months of follow-up, the findings of Horner syndrome were found to be partially resolved. First rib fracture associated with Horner syndrome is very rarely seen in children, and only 2 cases were found in English-language literature. Our case seems to be the third reported case. Horner syndrome should be kept in mind in cases of first rib fractures. When head trauma is considered, as it can be mistaken with anisocoria, this knowledge may help the surgeon in differential diagnosis.

RESUMO

BACKGROUND/PURPOSE: The significance of spot urine 5-hydroxyindoleacetic acid (5-HIAA) levels in the early diagnosis of acute appendicitis (AA) is questioned. METHODS: Forty young, pigmented, male rabbits were divided into 4 groups. Groups are summarized as follows: group 1, control (n = 10); group 2, laparotomy, sham (n = 10); group 3, peritonitis with cecal ligation and puncture (n = 10); and group 4, experimental appendicitis (n = 10). Spot urine samples were obtained for 5-HIAA determination, and appendectomy materials were examined histopathologically and peritoneal fluid cultures were obtained after 12 hours in the study groups. The results were analyzed statistically with 1-way analysis of variance and Scheffé and Tukey's HSD tests. RESULTS: The mean 5-HIAA levels in the control group was 5.7 +/- 0.6 mg/L, whereas it is 5.9 +/- 0.9 mg/L, 6.6 +/- 0.6 mg/L, 9.4 +/- 0.9 mg/L in the sham, peritonitis, and appendicitis groups, respectively. The levels of 5-HIAA in the appendicitis group were higher than those in the other groups, which was statistically significant (P < .001). CONCLUSIONS: Spot urine 5-HIAA determination may be a practical, objective, and noninvasive method in the early diagnosis of AA. Because other radiological and laboratory tests can be insufficient, especially in the early period of AA, this test may be used effectively instead. Clinical studies are necessary for further conclusions.

RESUMO

Cutaneous bronchogenic cysts (CBC) are rare solitary lesions which originate from primitive tracheobronchial tree. The periscapular location of these lesions is even a rare condition. The aim of this study is to evaluate this pathology after our case with literature review. An one-year-old girl was brought to our clinics with the complaint of a drainage at the back of her shoulder. In her physical examination, a hyperemic enduration with a sinus and purulent drainage was noted at the left scapular region. Ultrasonography revealed a lesion of 15x11 mm2 in size with a thick wall and a hypoechoic center. The lumen of the cyst was demonstrated with fistulography. Surgical excision of the lesion was performed and pathological examination revealed a cutaneous bronchogenic cyst. CBC have been reported in 64 cases in the literature. They are often found in the lower neck, sternum and shoulders. They arise due to abnormal bronchial budding during the embryological period. Only in 12 of these patients, including our case, the lesion was located in the periscapular area. Its treatment is surgical because of malignant transformation and infection. The recognition of this entity may help the surgeon for early diagnosis.

RESUMO

PURPOSE: Many treatment modalities have been described for thoracic empyema in children but the optimal timing of appropriate treatment remains controversial. The aim of this study is to find out the outcome of postpneumonic empyema in children after a conservative approach. METHODS: The reports of patients who were admitted to our hospital from January 1990 to October 2002 with a diagnosis of postpneumonic thoracic empyema were reviewed retrospectively. The comparative data were age, duration of prehospital illness, complaints, blood and pleural fluid analyses, radiological evaluations, microbiological studies, modes of treatment, duration of chest tube drainage, and length of hospital stay. RESULTS: A total of 115 patients (65 males and 50 females), aged from 3 months to 13 years, were evaluated. The most common symptoms were fever (96.5%), cough (85.2%), and dyspnea (50.4%). Chest X-rays revealed a minimal collection in 22 (19.2%), a moderate collection in 40 (34.8%), and a massive collection in 53 patients (46%). Staphylococcus aureus was the most common microorganism isolated from the bacterial cultures and Mycobacterium tuberculosis was the next most common. Twelve patients (10.4%) underwent surgical decortication. The mean duration of chest drainage was 10.1 +/- 1.39 days. The mean hospitalization period was 24.2 +/- 6.15 days and it was significantly shorter in patients with a minimal collection than in those with a massive collection (13.9 +/- 2.21 vs 28.47 +/- 6.38 days, P < 0.01). CONCLUSIONS: The majority of postpneumonic thoracic empyema cases in children can be successfully treated with a conservative approach. Detailed investigations should also be done to rule out tuberculosis in these patients.
