The efficacy of intermittent cervical traction in patents with chronic neck pain

Previous studies about the usefulness of traction therapy have concluded with conflicting results. The aim of this study was to examine its efficacy in chronic neck pain. Forty-two patients with at least 6 weeks of nonspecific neck pain were selected for the study. Data about demographic characteristics including age, sex, body mass index, duration of cervical pain, working status, smoking status, and regular exercise were recorded. Each patient was randomly assigned to Group 1-receiving only standard physical therapy including hot pack, ultrasound therapy and exercise program and Group 2-treated with traction therapy in addition to standard physical therapy. The patients were reevaluated at the end of the therapy. The main outcome measures of the treatment were pain intensity by visual analog scale (VAS), disability by neck disability index (NDI), and quality of life assessed by Nottingham Health Profile (NHP). Twenty-four female and 18 male patients with mean age of 48.2 +/- 11.5 years and a mean disease duration of 4.3 +/- 2.9 years were included to the study. There were no differences between the groups in terms of age, sex, pain intensity, and scores of NHP and NDI at entry. There were 21 patients in both groups. Both groups improved significantly in pain intensity and the scores of NDI and physical subscles of NHP at the end of the therapies (p < 0.05). There was an association between NDI and VAS pain scores in both groups (p < 0.05). No correlation was observed between clinical variables and age and duration of disease. In conclusion, no specific effect of traction over standard physiotherapeutic interventions was observed in adults with chronic neck pain. We suggest the clinicians to consider this condition and to focus on exercise therapy in the management of patients suffering from this condition.     

Unusual presentation: pulmonary hemosiderosis with celiac disease and retinitis pigmentosa in a child

Idiopathic pulmonary hemosiderosis (IPH) is a rare disease characterized by anemia, hemoptysis and recurrent alveolar hemorrhage. The combination of IPH and celiac disease (CD) is extremely rare. We report a 9-year-old boy with Lane-Hamilton syndrome, co-occurrence of pulmonary hemosiderosis with CD. This presentation is unique presentation because he has also retinal pigmentation.     

Computerized 3-dimensional study of the embryologic development of the human masticatory muscles and temporomandibular joint

PURPOSE: In this study, the development of human embryonic temporomandibular joint (TMJ) and masticatory muscles were investigated by using computed 3-dimensional reconstructions. MATERIALS AND METHODS: Sixteen human embryos and fetuses, ranging from 6.5 to 107 mm crown-rump length, were examined. RESULTS: At 10 weeks, a band of mesenchyme extending from the attachment of the lateral pterygoid muscle to the condylar process was observed to pass through the medial side of the condylar process to attach to the malleus. The temporal, masseter, and pterygoid muscles develop from the so called "temporal muscle" primordium, and the temporal muscle was in continuity with the masseter muscle until 14 weeks of fetal life. CONCLUSIONS: The study shows that the muscles of mastication arise from a single primordium. It also confirms the presence of a ligamentous attachment between the lateral pterygoid muscle and the malleus.     

Deviations of Mesial Root Canals of Mandibular First Molar Teeth at the Apical Third: A Micro–computed Tomographic Study

Introduction

The present study aimed to quantitatively analyze apical foramen deviations of mesial root canals of mandibular first molar teeth by means of micro–computed tomographic (micro-CT) imaging.

Premarital screening of beta-thalassemia trait in the province of Denizli, Turkey

A premarital screening program aiming at reducing the incidence of thalassemia major was started under the auspices of the Regional Health Administration in 1995 in the city of Denizli in the Aegean region of Turkey. In this report we assessed the 4-year results of the screening program. All couples who applied for marriage procedures were screened for beta-thalassemia trait by automatic red cell indices and Hb A(2) determination. The couples at risk were counseled and offered prenatal diagnosis and termination of pregnancy in case of an affected fetus. From October 1995 to August 1999, a total of 19,804 subjects (9,902 couples) were recruited for this study. The prevalence of beta-thalassemia trait with increased Hb A(2) was found to be 2.6% (514/19,804). In addition to the thalassemia trait, 22 patients (0.11%) had sickle trait. In 15 of the 9,902 couples, both partners were found to be carriers of the beta-thalassemia trait. After genetic counseling, 2 of the 15 planned carrier marriages were canceled. Seven couples declared that they do not want to have a child at present. Prenatal diagnosis was sought by 6 couples. One fetus was found to be normal, 4 had thalassemia minor and 1 had thalassemia major; this pregnancy was terminated by elective abortion. This study indicated that premarital screening is a very useful tool for detecting carrier couples and an effective way of controlling thalassemia major.     

Myeloid antigen expression provides favorable outcome in patients with adult acute lymphoblastic leukemia: a single-center study

Between July 1992 and July 2001, 81 patients with de novo adult acute lymphoblastic leukemia (ALL) treated according to the German Multicenter Study Group for Adult ALL (GMALL) 01/81 protocol were evaluated in order to analyze the effect of aberrant myeloid antigen expression on prognosis. We observed myeloid antigen aberrant expression in 21 of the adult ALL cases. We did not observe any effect of aberrant myeloid antigen expression on the time to achieve remission, relapse rate, and death rate. After 5 years of follow-up, cumulative disease-free survival of myeloid antigen (My) (+) and My (-) adult ALL patients was 67% and 43%, respectively. These data were not found to be statistically significant (P=0.29), but we did find a statistically significant difference in overall survivals between these two groups (85% vs 50%) (P=0.05). Twenty-nine patients died and the remaining 52 patients were followed for a median of 31 months. We could not find any special effect of the known prognostic factors on prediction of relapse in multivariate analysis. However, myeloid antigen expression was the most significant factor, which affected long-term survival in our patients (P=0.01). These data indicate that myeloid antigen expression is useful for predicting a favorable outcome of adult patients with ALL.     

Evaluation of leukocyte esterase and nitrite strip tests to detect spontaneous bacterial peritonitis in cirrhotic patients

AIM： To investigate the diagnostic efficacy of leukocyte esterase and nitrite reagent strips for bedside diagnosis of spontaneous bacterial peritonitis （SBP）. METHODS： A total of 63 consecutive patients with cirrhotic ascites （38 male, 25 female） tested between April 2005 and July 2006 were included in the study. Bedside reagent strip testing was performed on ascitic fluid and the results compared to manual cell counting and ascitic fluid culture. SBP was defined as having a polymorphonuclear ascites count of ≥ 250/mm^3. RESULTS： Fifteen samples showed SBP. The sensitivity, specificity, positive and negative predictive values of the leukocyte esterase reagent strips were; 93%, 100%, 100%, and 98%, respectively. The sensitivity, specificity, positive and negative predictive value of the nitrite reagent strips were 13%, 93%, 40%, and 77%, respectively. The combination of leukocyte esterase and nitrite reagents strips did not yield statistically significant effects on diagnostic accuracy. CONCLUSION： Leukocyte esterase reagent strips may provide a rapid, bedside diagnostic test for SBP.     

Germline mutations of aryl hydrocarbon receptor-interacting protein (<Emphasis Type="Italic">AIP</Emphasis>) gene and somatostatin receptor 1–5 and <Emphasis Type="Italic">AIP</Emphasis> immunostaining in patients with sporadic acromegaly with poor versus good response to somatostatin analogues

Objective

To determine aryl hydrocarbon interacting protein (AIP) gene variations and AIP and somatostatin receptor (SSTR) 1–5 immunostaining in patients with apparently sporadic acromegaly with poor versus good response to somatostatin analogues (SRLs).

Methods

A total of 94 patients (66 with poor and 28 with good response to SRLs) were screened for the AIP gene variations using Sanger sequencing. Immunostaining was performed in 60 tumors.

Results

Several variations, albeit some with undetermined significance, were detected, especially in poor responder patients. The prevalence of AIP mutation was 2.1% in the whole group and 1.5% in patients with poor response to SRLs. AIP, SSTR2A, and SSTR2B immunostainings were decreased in patients with poor response (p?<?0.05 for all), and other SSTRs did not differ between the groups (p?>?0.05 for all). Patients with low AIP had decreased levels of SSTR2A and SSTR3 (p?<?0.05 for all). AIP and SSTR2A immunostainings were positively correlated to the treatment response and age at diagnosis was negatively correlated (p?<?0.05 for all). In poor responder patients with high SSTR2A immunostaining, SSTR2B immunostaining and preoperative tumor size were positively and negatively correlated, respectively, to SRL response (p?<?0.05 for all).

Conclusions

Lack of response to SRLs does not necessarily increase the risk of harboring AIP mutations. The finding of decreased AIP, SSTR2A, and SSTR2B immunostaining in patients with poor response to SRLs and decreased SSTR2A and SSTR3 level in those with low AIP immunostaining suggests a possible interaction between AIP and some SSTR subtypes that might alter SRL sensitivity.

     

Evaluation of serum zonulin level in prediabetic patients

BackgroundThis study aimed to investigate the relationship between lipopolysaccharide (LPS) and zonulin levels and also to show the effect of acute hyperglycemic stress induced by oral glucose tolerance testing (OGTT) on zonulin levels in pre-diabetic patients.MethodsFour groups were constituted according to the criteria of the American Diabetes Association (ADA), based on OGTT results: control group (n:40); prediabetic group (n:56), divided into two subgroups: impaired fasting glucose group (IFG) (n:36), and impaired glucose tolerance (IGT) + IFG group (n:20) and type-2 diabetes mellitus (T2DM) group (n:45).ResultsZonulin and LPS did not significantly differ between the prediabetes and control groups, but were significantly higher in the T2DM group compared to both the prediabetic and the control group (P < 0.001). After OGTT, zonulin and LPS were significantly higher in the prediabetes group compared to the control group (P < 0.01 and P < 0.05, respectively), and significantly lower in the IFG and IFG + IGT groups compared to the T2DM group (P < 0.001, P < 0.001 and P < 0.001, P < 0.001, respectively). A positive correlation was detected between fasting zonulin and 2-hour zonulin (r = 0.727, P < 0.001) and between fasting LPS (r = 0.555, P < 0.001) and 2-hour LPS (r = 0.567, P < 0.001) in the prediabetic group. Increased zonulin and LPS levels and the positive correlation between these levels during the prediabetic period although non significant suggests onset of intestinal permeability.ConclusionsDuring acute hyperglycemia in prediabetic patients, up-regulation of zonulin and LPS may affect intestinal function. The intestines may play a key role in up-regulation of glucose and the pathogenesis of diabetes.
