Iron deficiency anemia in the elderly: prevalence and endoscopic evaluation of the gastrointestinal tract in outpatients

Iron deficiency anemia (IDA), mostly due to chronic occult bleeding from the gastrointestinal tract, is a common problem in the elderly. This study aimed to determine the prevalence of IDA in the elderly and to investigate the gastrointestinal tract in elderly patients with IDA. 1,388 patients over 65 years were prospectively evaluated for IDA in our outpatient clinic. IDA was defined if decreased hemoglobin concentrations (<13 g/dl for men and <12 g/dl for women) were associated with low serum ferritin levels (<15 ng/ml in men and <9 ng/ml in women). We evaluated the gastrointestinal system of all patients with IDA by upper gastrointestinal endoscopy and colonoscopy regardless of fecal occult blood loss. The prevalence of anemia was found to be 25% (n = 347) in our study population, and 30.5% (n = 106) of these patients with anemia had iron deficiency. Upper gastrointestinal endoscopy and colonoscopy were performed in 96 patients with IDA. Fifty-eight upper gastrointestinal system lesions (55 patients, 57.3%) and 27 colonic lesions (26 patients, 27.1%) were detected. We diagnosed gastrointestinal malignancy in 15 (15.6%) elderly patients with IDA (8 colon, 1 esophageal and 6 gastric cancers). IDA is a common problem in elderly patients; consequently, before iron replacement therapy, patients should be thoroughly investigated regarding a possible association with gastrointestinal malignancy.     

Post-traumatic pseudoaneurysm of the brachial artery and its surgical treatment

The frequency of peripheral artery aneurysms in the upper extremities is much less than in the lower extremities. Diagnosis and surgical treatment are important because upper extremity aneurysms can cause severe decreases in function and lead to the loss of an arm or of fingers. We performed aneurysmal resection together with saphenous vein graft interpositioning in 9 patients with a diagnosis of post-traumatic brachial pseudoaneurysm from January 1995 through February 2003. Of these patients, 7 were men (77%). The mean age was 38.2 years (range, 26-46 years. Four patients had gunshot wounds (44%) and 5 had stab wounds (56%). The mean duration from injury to hospital admission was 26.7 months (range, 17 months-7 years). All patients underwent color-flow arterial Doppler ultrasonography and selective upper extremity digital subtraction angiography. In all patients, we performed aneurysmal resection and saphenous vein graft interpositioning. There was no instance of death or ischemic extremity loss. Patients were discharged from the hospital a mean of 3.2 days after surgery (range, 2-6 days). Early and late graft patency rates were 100%. We followed the patients' cases for a mean of 3.4 years (range, 1 month-7 years). Very rarely, post-traumatic upper extremity pseudoaneurysms show symptoms after a long period of time. Diagnosis is very easy with a review of the patient's history and a physical examination; surgical reconstruction is the preferred treatment for such patients.     

Povidone iodine in the treatment of adenoviral conjunctivitis in infants

Context: Adenoviral conjunctivitis.

Objective: To examine the effects of conjunctival irrigation with povidone iodine in infants with adenoviral conjunctivitis.

Material and methods: An outbreak of adenovirus conjunctivitis occurred between September and December 2012 at the neonatal intensive care unit of our hospital. Forty-three infants with adenoviral conjunctivitis were examined in this study. Thirty-five eyes of 35 infants who had detailed ophthalmological examination and clinical scoring were included. The conjunctiva of 15 infants (Group 1) were irrigated with povidone iodine 2.5% solution and then treated with preservative-free artificial tears and preservative-free antibiotic drops. Twenty infants (Group 2) were treated only with the same drops with the same posology, without conjunctival irrigation with povidone iodine. Patients were examined two times a week until the complete recovery. Lid edema, conjunctival chemosis, fragility of conjunctival vasculature, pseudomembrane formation, and corneal involvement were scored clinically.

Results: Twenty patients (57%) were female and 15 patients (43%) were male and mean age was 3.1 months (ranged from 1 to 4 months). No relation was found between gender and clinical scores. Statistically significant lower clinical scores were obtained from Group 1. The median recovery time was earlier in Group 1 (7?d) than Group 2 (12?d) (p?=?0.001).

Conclusion: Conjunctival irrigation with 2.5% povidone iodine is effective in the treatment of adenoviral conjunctivitis in infants.     

Is there any relationship between adverse pregnancy outcome and first trimester nuchal translucency measurements in normal karyotype fetuses?

Aim: This study aims to research whether there is a relationship between first trimester nuchal translucency (NT) measurements and pregnancy complications such as gestational diabetes mellitus (GDM), gestational hypertension (GHT), intrauterine growth restriction (IUGR) and oligohydramnios.

Method: This study included 225 singleton pregnancies attending Canakkale Onsekiz Mart University Obstetrics and Gynecology clinic for all monitoring and examinations, and gave birth at our clinic between January 2011 and December 2012. Data sources were clinical records and the hospital's automation system, and the study was planned as retrospective cohort. NT measurement was made between 10 weeks 3 days and 13 weeks 6 days gestation. For data analysis, the chi-square, Mann–Whitney U test and Spearman correlation were used.

Results: Of pregnancies, in the study, 5 (2.2%) developed GDM, 6 (2.6%) developed GHT, 2 (0.89%) developed IUGR and 10 (4.4%) developed oligohydramnios. There was no correlation identified between NT measurements and development of GDM, GHT, IUGR and oligohydramnios.

Conclusion: There was no relationship found between first trimester NT measurements and complications that could develop in pregnancy. For the first time in the literature, NT and oligohydramnios were studied and no relationship was observed.     

Reliability and Validity of the Turkish Version of the Abiloco-Kids

ABILOCO-Kids is a scale that assesses the walking ability of children with Cerebral Palsy (CP) from the viewpoint of parental perception. The aim of this study was to translate the ABILOCO-Kids scale into Turkish and to establish its reliability and validity in children with CP. Turkish children were recruited in this study. ABILOCO-Kids is a scale developed by Caty and et al. This scale assess the walking ability of children with CP focusing on the activity domain of the International Classification of Functioning, Disability and Health (ICF). The ABILOCO-Kids scale was translated from English into Turkish using the forward-backward-forward method. The motor functions of the 63 children participating in the study were evaluated by the Gross Motor Function Classification System (GMFCS) and the Gross Motor Function Measurement-88 (GMFM-88). The ABILOCO-Kids scale was repeated in 30 children after one week to establish test-retest reliability. While internal and external construct validity were investigated using Rasch analysis and Spearman correlation coefficient, respectively; reliability was evaluated in terms of internal consistency by Cronbach’s alpha and Person Separation Index (PSI). All items of the ABILOCO-Kids were found to fit the Rasch Model (chi-square 14.35 (df?=?20), p?=?0.813). The internal construct validity was good, overall mean item fit residual was ?0.109 (SD: 0.719) and mean person fit residual was ?0.215 (SD: 0.817). The reliability was good with Cronbach’s Alpha of 0.98 and PSI of 0.99. When the test-retest was examined via Differential Item Functioning (DIF) by time, none of the items showed DIF. Spearman correlation coefficients of the ABILOCO-Kids scale in relation to the GMFM and GMFCS were r?=?0.824, p?<?0.001; r?=??0.788, p?<?0.001 respectively. The Turkish version of the ABILOCO-Kids scale is a valid, reliable and unidimensional scale for children with CP. This scale will allow the differences in the locomotion of children with CP to be evaluated from the perspective of the family.     

Quantitative assessment of thyroid gland elasticity with shear-wave elastography in pediatric patients with Hashimoto’s thyroiditis

Objective

Hashimoto’s thyroiditis is the most common autoimmune thyroid disorder in the pediatric age range. Measurement of thyroid gland size is an essential component in evaluation and follow-up of thyroid pathologies. Along with size, tissue elasticity is becoming a more commonly used parameter in evaluation of parenchyma in inflammatory diseases. The aim of the current study was to assess thyroid parenchyma elasticity by shear-wave elastography in pediatric patients with Hashimoto’s thyroiditis; and compare the elasticity values to a normal control group.

Materials and methods

In this study; thyroid glands of 59 patients with a diagnosis of Hashimoto’s thyroiditis based on ultrasonographic and biochemical features, and 26 healthy volunteers without autoimmune thyroid disease and thyroid function disorders, were evaluated with shear-wave elastography. Patients with Hashimoto thyroiditis were further subdivided into three categories based on gray-scale ultrasonography findings as focal thyroiditis (grade 1), diffuse thyroiditis (grade 2), and fibrotic thyroid gland (grade 3).

Results

Patients with Hashimoto’s thyroiditis (n = 59) had significantly higher elasticity values (14. 9 kPa; IQR 12.9–17.8 kPa) than control subjects (10.6 kPa; IQR 9.0–11.3 kPa) (p < 0.001). Of the 59 patients with Hashimoto’s thyroiditis, 23 patients had focal thyroiditis involving less than 50% of the gland categorized as grade 1, 24 patients had diffuse involvement of the thyroid gland categorized as grade 2, and 12 patients had marked hyperechoic septations and pseudonodular appearance categorized as grade 3 on gray-scale ultrasound. Based on elastography, grade 3 patients had significantly higher elasticity values (19.7 kPa; IQR 17.8–21.5 kPa) than patients with grade 2 (15.5 kPa; IQR 14.5–17.8 kPa) and grade 1 thyroiditis (12.8 kPa; IQR 11.9–13.1 kPa) (p < 0.05). Patients with grade 2 thyroiditis had significantly higher elasticity values than those with grade 1 thyroiditis (p < 0.05).

Conclusion

Gray-scale ultrasound findings of heterogeneous echotexture and hypoechoic echogenicity reflect a longer duration of inflammation and may not be found in the initial stages of thyroiditis. Our results indicate that shear-wave elastography could be used to evaluate the degree of fibrosis in Hashimoto’s thyroiditis.

     

Evaluation of spirometric and pulmonary haemodynamic parameters in patients with COPD

In this study we aimed to asses the association between the spirometric test which is known to be an indicator of severity of the disease and pulmonary artery pressure, in patient chronic obstructive pulmonary disease (COPD). Study population consisted of 51 patients with COPD. Severity of the disease was graded by the criteria of European Respiratory Society; mildly obstructive 5 patients (FEV1 > 70%), moderately obstructive 10 (FEV1= 50-69%), severely obstructive 36 patients (FEV1 < 50%). Measurement of pulmonary artery pressure was performed bt microcatheterisation method. Statistical analysis was performed between two groups; group I consisted of mildly and moderately obstructive patients, and group II severely obstructive patients. Pulmonary artery pressure of the group II patients was significantly higher than that of group I patients (27 +/- 4 mmHg vs 22 +/- 1.6 mmHg, respectively p< 0.001). There were also statistically significant difference between group I and group II in respect to FEV1% (63 +/- 7 vs 28 +/- 9 respectively p< 0.001), FEV1 L (1.84 +/- 0.46 vs 0.89 +/- 0.36 respectively p< 0.001), FEV1/FVC (71 +/- 10 vs 53 +/- 11 respectively p< 0.001), FVC% (73 +/- 8 vs 47 +/- 10 respectively p< 0.001), and MMF% (38 +/- 13 vs 15 +/- 6 respectively p< 0.001). Pulmonary artery pressure and diameter of right descending pulmonary artery on chest X-ray of the patients were negatively correlated with FEV1%, FEV1 L, FVC and MMF (p< 0.001 for all). We have shown pulmonary artery pressure of the patients with COPD was negatively correlated with the spirometric parameters such as FEV1%, FEV1 L, FVC and MMF. So FEV1 < 50% can be used as an indicator of increased pulmonary artery pressure in patients with COPD.
