Serum fructosamine correlates with gingival index in children with insulin-dependent diabetes mellitus (IDDM)

Abstract Fructosamine assay, which is used in diagnosing and monitoring diabetic patients, is compared with the hemoglobin and plasma glucose assays in children and adolescent insulin-dependent diabetes mellitus patients. We demonstrated that the gingival index scores were correlated with fructosamine values in insulin-dependent diabetes mellitus patients but not in non-diabetic controls. We also found that there was no correlation between gingivitis scores and fasting plasma glucose and HbAlc values. Periodontitis was found to be rare in diabetic children and adolescents.     

Determination of allelic deletion of multiple endocrine neoplasm type 1 (MEN1) gene in acute myeloid leukemia (AML) by application of FISH-TSA technique

We have used the single and dual color fluorescence in situ hybridization (FISH) technique combined with a new detection system, tyramide signal amplification (TSA), by using the multiple endocrine neoplasm type 1 (MEN1) gene and chromosome 11 specific alpha satellite DNA probes for the study of the allelic deletion of the MEN1 gene. The MEN1 gene is a new tumor suppressor gene and has been recently cloned on chromosome 11q13. FISH combined with the TSA detection system was performed on bone marrow interphase nuclei of 22 patients with acute myeloid leukemia (AML). The FISH-TSA analysis revealed the mono allelic deletion of the MEN1 gene in 4 out of 22 patients (18.18%), 2 of 9 AML-M2 patients (22.2%), 1 of 6 AML-M4 patients (16.6%), and 1 of 4 AML-M5 patients (25.0%). Our study indicates that allelic deletion of the MEN1 gene is not a major cause or a primary event in tumorigenesis of AML, although the long arm (q13 region) of chromosome 11 involves a chromosomal rearrangement in AML.     

MBL,P2X7, and SLC11A1 gene polymorphisms in patients with oropharyngeal tularemia

Conclusion: A significant association was found of oropharyngeal tularemia with SLC11A1 allele polymorphism (INT4?G/C) and MBL2 C?+?4T (P/Q). These results indicate C allele and Q allele might be a risk factor for the development of oropharyngeal tularemia.

Aim: This study aimed to investigate the relationship of SLC11A1, MBL, and P2X₇ gene polymorphism with oropharyngeal tularemia.

Methods: The study included totally 120 patients who were diagnosed with oropharyngeal tularemia. Frequencies of polymorphisms in the following genes were analyzed both in the patient and control groups in the study: SLC11A1 (5’(GT)_n Allele 2/3, Int4?G/C, 3’ UTR, D543N G/A), MBL (MBL2 C?+?4T (P/Q), and P2X₇ (?762 C/T and 1513 A/C).

Results: Among all polymorphisms that were investigated in this study, SLC11A1 gene showed a significance in the distriburtion of polymorphism allelle frequency at the INT4 region. Frequency of C allele was 54 (28%) in patients with oropharyngeal tularemia, and 31 (13%) in the control group (p?=?0.006 and OR = 1.96 (1.21–3.20)). An association was detected between MBL2 C?+?4T (P/Q) gene polymorphism and oropharyngeal tularemia (p?7 (?762 C/T and 1513 A/C) gene polymorphism and oropharyngeal tularemia in this study (p?>?0.05).     

Associations analysis of GSTM1, T1 and P1 Ile105Val polymorphisms with carpal tunnel syndrome

Oxidative stress was related with carpal tunnel syndrome (CTS). We aimed to clarify the associations between glutathione S-transferase (GST)M1, GSTT1 and GSTP1-Ile105Val polymorphisms and CTS. One hundred-forty patients with CTS and 97 healthy controls were enrolled in this study. Tinel and Phalen signs were noted as positive or negative. Functional and clinical status of patients was evaluated by the Boston Questionnaire. The intensity of hand and/or wrist pain was evaluated on 10 cm visual analog scale (VAS). We applied the polymerase chain reaction (PCR) to determine the polymorphisms of the GSTM1 and GSTT1 and the PCR-restriction fragment length polymorphism method for detecting the GSTP1-Ile105Val polymorphism. The M1 null genotype was significantly higher in patients with CTS compared to healthy controls, and the M1 null genotype seemed to increase the risk of CTS approximately two-fold (P?=?0.011; odds ratio (OR)?=?1.98; 95 % confidence interval (CI) 1.17–3.36). The M1 null, T1 present combined genotype was significantly higher in patients with CTS compared to healthy controls (P?=?0.043); however, it seemed not to increase the risk of CTS (P?=?0.14; OR?=?0.62; 95 % CI 0.33–1.76). We found significantly higher levels of the VAS, Boston Symptom Severity Scale and Phalen sign in patients with the Ile/Val or the Val/Val genotypes compared to those in patients with the Ile/Ile genotype (P?=?0.003, 0.004 and 0.044, respectively). We proposed that genes involved in the protection from oxidative stress may influence the susceptibility, clinical and functional status of CTS. The GSTM1 null genotype may be related with the development of CTS, whereas the Val allele of GSTP1-Ile105Val polymorphism may be associated with worse functional and clinical status in CTS.

Surgery of cardiac hydatid cysts. Experience of 39 years

In some countries, Hydatidosis is a common public health problem but cardiac hydatid cysts are rarely observed. The evaluations of operative results and follow up of cardiac hydatid cases. Twenty-five consecutive unselected patients suffering from cardiac hydatidosis and operated on between 1967 and 2006 in Siyami Ersek Cardiothoracic and Vascular Surgery Center were retrospectively analyzed. In 10 of these patients the hydatid cyst was intracardiac, while in 13 patients cysts were extracavitary but located into the pericardium. In 2 patients the hydatid cyst was both intra and extracavitary. Mean age of the patients was 31+/-9.2. The female/male ratio was 17/8. The 12 patients with intracavitary and 2 patients wit extracavitary hydatid cysts were operated on with the aid of extracorporeal circulation. One patient died postoperatively. In one patient recurrence of the hydatidosis was observed. The majority of cases in previous publications were located in the left side of the heart. In our series, most were located in the right heart. In such cases clamping the pulmonary artery is mandatory to prevent pulmonary migration. Careful resection is important for prevention of recurrence.     

Contribution of DOG1 expression to the diagnosis of gastrointestinal stromal tumors

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract, and the majority contain KIT or PDGFRA-activating mutations. However, up to 10% of GISTs are c-kit-negative. Antibodies with increased sensitivity and specificity for the detection of c-kit-negative GIST cases may be of value, especially because some of these cases may also benefit from tyrosine kinase inhibitor therapy.     

Intraoral reconstruction with “thinned” peroneal artery perforator flaps: An alternative to classic donor areas in comorbid patients

Free fasciocutaneous flaps like the radial forearm free flap (RFFF) and the anterolateral thigh (ALT) are the most commonly used flaps in intraoral reconstruction. However, certain conditions preclude the use of either of these flaps. The aim of this report was to show applicability of “thinned” peroneal artery perforator (PAP) flaps in intraoral reconstruction. We report two cases of squamous cell carcinoma involving the tongue and floor of the mouth, where one patient had advanced scleroderma with tight forearm skin and the other with a history of Reynaud's disease precluding the use of RFFF. In addition, both patients were morbidly obese with thick adipose tissue in the thigh making ALT flap not a suitable option. Instead, a PAP flap was chosen. After the harvest, the subcutaneous tissue thickness was measured to be 2.2 and 1.8 cm, respectively. The thinning was performed by removing the deep fat lobules of the superficial fat layer down to a final thickness of 0.4 and 0.3 cm, respectively. A 2 × 2 cm area surrounding the perforators were kept untouched. Both patients had uneventful postoperative course with one patient having a small donor area dehiscence that healed with local wound care. The functional outcomes at 1 year were good. “Thinned” PAP flap is a unique and novel application that may be an alternative in intraoral reconstruction when primary choices are not available. © 2014 Wiley Periodicals, Inc.
