Evaluation of dentofacial asymmetry caused by odontomas using panoramic radiographs.

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.

Evaluation of micronuclear frequencies in both circulating lymphocytes and buccal epithelial cells of patients with oral lichen planus and oral lichenoid contact reactions.

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.].

Increased frequency of restless legs syndrome in atopic dermatitis.

BACKGROUND: Restless legs syndrome (RLS) is characterized by an unpleasant sensation in the legs, which is difficult to describe, but produces an urge to move the legs frequently. AIM: To assess the prevalence and severity of RLS in patients with atopic dermatitis (AD) and patients with psoriasis, and to investigate the factors potentially associated with RLS. METHODS: In total, 253 people were enrolled (120 with AD, 50 with psoriasis and 83 healthy controls). A diagnosis of RLS was made according to the criteria of the International RLS Study Group (IRLSSG), and severity was assessed using the IRLSSG severity scale. RESULTS: RLS was significantly more common in patients with AD (40.8%) than in patients with psoriasis (18.0%) or in controls (10.8%) (P<0.01 and P<0.001, respectively). Prevalence of RLS was higher in patients with active AD than in those with inactive AD (55.3% vs. 23.6%) or controls. There was a significant difference in RLS prevalence between patients with active and those with iactive AD, between patients with active AD and healthy controls, between patients with active AD and patients with psoriasis, and between patients with inactive AD and healthy controls (P<0.001, P<0.001, P<0.001, P=0.04, respectively). There was no significant difference in RLS prevalence between patients with active AD and patients with psoriasis, or between patients with psoriasis and healthy controls (P>0.05). Of patients who were positive for RLS, 56.9% had a family history of atopy and 40.3% had a family history of RLS, and there was a significant relationship between the presence of RLS and family history of atopy or RLS (P<0.001 for both). CONCLUSIONS: RLS is common in patients with AD, particularly in those with active disease.

Prevalence of inguinoscrotal pathologies and risk factors in a cohort of 388 children with spina bifida.

BACKGROUND: There is limited information about the prevalence and risk factors of inguinal hernia and undescended testis in patients with spina bifida (SB). The aim of this study was to identify the properties and prevalence of inguinoscrotal diseases in these patients. METHODS: A questionnaire was completed by parents of patients with the diagnosis of SB in our center. Together with demographic data, presence an of inguinal hernia, side, operation history, presence of ventriculoperitoneal (VP) shunt, type of SB aperta or occulta, recurrence and presence of undescended testis were questioned. Patients were grouped into 2 as SB aperta and occulta. The prevalence of these pathologies and their clinical properties were evaluated. RESULTS: In this study, 388 patients were evaluated. Of these, 238 patients had SB aperta and 150, SB occulta. There was no significance in comparison of gender. The prevalence of inguinal hernia was 12.6% in general. A hernia was noted in 37 SB aperta patients (15.6%) whereas this was seen in 12 of the SB occulta patients (8%) (p=0.029). When there was a VP shunt, hernia prevalence was 21.5% and when there was no shunt, this ratio was 7.1% (p=0.0001). Prevalence of inguinal hernia was 21.8% in males and 3.2% in females (p=0.0001). When there was a VP shunt with SB aperta the prevalence was 21.9% and when a VP shunt was present with SB occulta, this number was found to be 13.3% (p=0.006). The prevalence of undescended testis was 17.7% and there was no difference between SB aperta and occulta patients. CONCLUSIONS: Inguinal hernia and undescended testis are more frequent in SB patients when compared to the normal population. VP shunts and male gender may be risk factors for inguinal hernia in these children. These findings may imply neurological factors in the etiology of inguinal hernia and undescended testis.

Alkaline phosphatase: can it be considered as an indicator of liver fibrosis in non-alcoholic steatohepatitis with type 2 diabetes?

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).

Protective effect of the thoracic cage on parenchyma in response to trauma direction in blunt thoracic trauma: an experimental study.

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.

Micronuclear and sister chromatid exchange analyses in peripheral lymphocytes of patients with oral lichen planus--a pilot study.

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.

Does autonomic dysfunction play a role in atopic dermatitis?

BACKGROUND: Atopic dermatitis (AD) is a chronic dermatitis characterized by intense itching and excessive skin dryness. The factor most commonly blamed for the pathogenesis of skin dryness in the disease is impaired barrier function of the stratum corneum. However, there are findings indicating that the autonomic nervous system, and the sympathetic nervous system in particular, is affected negatively in AD, and thus, autonomic dysfunction can be an important factor leading to skin dryness. OBJECTIVE: In this study we aimed to evaluate the functioning of the autonomic nervous system electrophysiologically using R-R interval variation (RRIV) and the sympathetic skin response (SSR) in patients with AD, and to examine whether there is an underlying autonomic nervous system dysfunction. PATIENTS AND METHODS: The study registered a total of 38 (12 males and 26 females) patients with AD, of whom 24 had active and 14 inactive disease, and 20 (10 males and 10 females) healthy control subjects. RRIV was used in our study as the electrophysiological test to evaluate the parasympathetic system. The SSR method, which is a noninvasive electrophysiological test with a significant role in evaluating the sudomotor activity of skin, as well as that of the unmyelinated fibres that take a part in this activity, was employed to assess the sympathetic nervous system. RESULTS: Our study revealed a significantly prolonged SSR latency and amplitude of the upper extremity in the patient group, relative to the control group (P < 0.05). When the group with active skin lesions was compared with the control group, the former was found to have prolonged SSR latency and amplitude in the upper extremity. The prolongation in SSR latency of the upper extremity was statistically significant (P < 0.05), while the prolongation in amplitude was not (P = 0.5). An evaluation of RRIV results did not show a significant difference between the patient and control groups. CONCLUSIONS: These findings demonstrate that the sudomotor activity controlled by the sympathetic nervous system, as well as unmyelinated fibres that play a role in this activity are affected in patients with AD. We think that the involvement of sudomotor activity may be one of the causes that leads to dysfunction in sweat glands and skin dryness.

Characteristics and medical management of patients with rheumatoid arthritis and ankylosing spondylitis.

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.

Factors affecting renal scar development in children with spina bifida.

BACKGROUND/AIMS: Prevention of renal scarring is the main therapeutic goal in children with spina bifida. We aimed to determine factors affecting renal scar development in these patients. MATERIALS AND METHODS: Records of 312 children admitted between 1994 and 2005 with spina bifida were reviewed. Age on admission, gender, presence of previous febrile urinary tract infections (UTIs), vesicoureteral reflux (VUR), and initial urodynamic findings were noted. Patients were grouped regarding presence/absence of renal scars on DMSA scans. Chi2 and Student's t tests were used for statistical evaluation. RESULTS: Seventy-two patients had renal scars on admission. Mean age was 4.62 +/- 4.59 years for patients without renal scars and 6.35 +/- 4.9 years for patients with scars. Male/female ratio was 1:1 in the scarless group and 1:2 in the group with scars. Previous febrile UTI was present in 11 of 240 scarless patients in contrast to 7 out of 72 patients in the scar group (p > 0.05). VUR was present in only 16.3% of cases without scars, whereas 36.1% of patients in the scar group had VUR. Detrusor overactivity and detrusor sphincter dyssynergia were observed in 67.1% of scarred patients, whereas this figure was 42.4% in the scarless group. The comparison of age on admission, gender, detrusor overactivity, and detrusor sphincter dyssynergia revealed significant differences between patients with and without renal scars. CONCLUSIONS: Late referral, female gender, overactive detrusor, and detrusor sphincter dyssynergia have detrimental effects on renal parenchymal function in spina bifida patients. Patient selection for aggressive treatment using these features may prevent renal parenchymal deterioration.

Hepatic pseudocyst as a result of ventriculoperitoneal shunts: case report and review of the literature.

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.

The efficacy of conservative treatment for late term ovarian torsion.

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.

Nitric oxide and endothelin relationship in intestinal ischemia/reperfusion injury (II).

Endothelins ( ETs ) are potent vasoconstrictors derived from vascular endothelium. They have primary roles in many pathophysiologic states including ischemia/reperfusion (I/R) injury. The relationships between nitric oxide (NO) and ETs are still under investigation. In this study on rats we want to focus on the interaction of NO and ET especially in I/R injury. For this purpose ET-1 and PD-156252, a nonselective ET receptor blocker, were given in a mesenteric I/R model and reactive oxygen species were detected directly using chemiluminescence of the ileal tissue. ET administrations to sham and I/R groups caused significant increases in NO concentrations whereas, in terms of peroxynitrite, which is a highly reactive group of free radicals, its increasing effects were seen only in I/R groups. This suggests that in I/R where superoxide levels increase together with NO, the conversion to peroxynitrite is likely and this effect is augmented with ET administration. On the other hand PD administration decreases superoxide and thereby peroxynitrite levels and this study shows that the effect of PD-156252 is established through this mode of action. These data suggest therapeutic approaches that may be beneficial in the treatment of I/R injury.

The effect of trapidil on the reactive astrocytic proliferation following spinal cord trauma in rats: light and electron microscopic findings.

Platelet-derived growth factor (PDGF) released from platelets is one of the mitogens in serum, which plays a major role upon the cell biology, namely enhancing cell division and controlling of the maturation, especially upon the glial cell growth and its differentiation. Trapidil, which is an anti-PDGF agent, inhibits the effect of PDGF, especially the proliferative effects on the glial and tumoral cells in vitro. Previous studies suggested that the astrocytic proliferation stimulated by PDGF was inhibited by trapidil via the selective antagonism. Trapidil was not found to have a considerable effect on the prevention of nonpermissive astrocytes in this study. It should be theorized that trapidil, administered immediately even after the trauma, could not reach the injury site in effective measure because of secondary events such as edema and impairment of blood circulation. This suggestion should be another subject for studies concerning trapidil which is administered prior to the trauma.

The effect of trapidil on the reactive astrocytic proliferation following spinal cord trauma in rats: Light and electron microscopic findings.

Platelet-derived growth factor (POCF) released from platelets is one ofthe mitogens in serum, which plays a major role upon the cell biology, namely enhancing cell division and controlling of the maturation, especially upon the glial cell growth and its differentiation. Trapidil, which is an anti-POCF agent, inhibits the effect of POCF, especially the proliferative effects on the glial and tumoral cells in vitro. Previous studies suggested that the astrocytic proliferation stimulated by POCF was inhibited by trapidil via the selective antagonism. Trapidil was not found to have a considerable effect on the prevention of nonpermissive astrocytes in this study. It should be theorised that trapidil, administered immediately even after the trauma, could not reach the injury site in effective measure because of secondary events such as edema and impairment of blood circulation. This suggestion should be another subject for studies concerning trapidil which is administered prior to the trauma. [Neural Res 1998; 20: 365-373].

The effect of collagen, interleukin-1 alpha and glicosaminoglycan on the neovascularization of central nervous system.

Neovascularization, the development of a new microvasculature, has an important role in physiological and pathological processes. The vascular changes in the brain can be easily detected because the proliferation of endothelial cells in its vascular structure is quite small, and so constitutes a good model for neovascularization studies. In the present investigation, to induce intracerebral neovascularization, we implanted collagen, Interleukin-1 alpha (IL-1 alpha) and glicosaminoglycan into the brain of pigs, in order to test the hypothesis that IL-1 alpha, collagen and glicosaminoglycan play a pivotal role in the process of neovascularization. Both pure collagen and collagen combined with IL-1 alpha induced neovascularization according to light-electron microscopic findings and values of enzymes' activities. In particular, collagen combined with IL-1 alpha synergically affected the increase of neovascularization. However, glicosaminoglycan did not affect it significantly. Although the results of this study provided us with some interesting data indicating the beneficial effects of collagen combined with IL-1 alpha on neovascularization, further studies should be done to study the short term effect of these biochemical substances.

An unusual presentation of patent urachus: report of a case.

Congenital umbilical disorders are frequently seen in the pediatric population and are mostly classified as retained umbilical cord structures or failure of umbilical ring closure. Vitelline duct anomalies, urachal anomalies and umbilical herniations comprise the main group of these congenital problems. Here we report a new presentation of vesicoumbilical patency in a 20-day-old male baby. A brief review of the literature concerning the classification of patent urachus to explain the possible mechanism of the anomaly is given.

The effects of a pulmonary rehabilitation program on pulmonary function tests and exercise tolerance in patients with Parkinson's disease.

The effects of exercise training, as a part of a pulmonary rehabilitation program, on pulmonary function tests and exercise tolerance have not been clarified in patients with Parkinson's disease (PD). This study compares the results of pulmonary function test parameters and exercise tolerance in individuals with and without PD. It also compares the results of pulmonary function test parameters, exercise tolerance and subjective ratings of perceived exertion (RPE) between entry to and the end of exercise training program in patients with PD. Nine patients with PD and 9 age-matched healthy controls participated in the study. Pulmonary function tests and a six-minute walk test were performed in subjects with and without PD, and the Borg RPE scale was applied to patients with PD at the beginning of the study. After the exercise training program, all parameters were recorded again in patients with PD. Statistically significant differences were observed between the groups in some of the pulmonary function test parameters and in exercise tolerance. After the training program, we observed improvement in some of the pulmonary function test parameters, exercise tolerance, and RPE in patients with PD.

Horner's syndrome secondary to tube thoracostomy.

Tube thoracostomy is a common therapeutic approach applied in medical practice. Certain complications of this procedure have been described in the literature. Oculosympathetic paresis, or Horner's syndrome, occurs from the interruption of second order preganglionic neurons and manifests as miosis, ptosis, hemifacial anhidrosis and enophthalmos. Iatrogenic Horner's syndrome, on the other hand, very rarely couples with tube thoracostomy. Only seven cases have been described in the literature, two of whom were in the pediatric age group. Herein we present a three-year-old girl operated for diaphragmatic hernia who later developed Horner's syndrome at the same side of the thorax tube. Upon the development of the pathology, the tube was repositioned and after one month only a slight ptosis persisted. Our patient seems to be the third case described in the literature. The clinical significance of this pathology is assessed in this report.
