Comparison of Negative Pressure Wound Therapy (NPWT) and Classical Wet to Moist Dressing (WtM) in the Treatment of Complicated Extremity Wounds in Children.

Treating complicated wounds in the pediatric population using traditional wet to moist wound dressing methods is not always appropriate due to the frequent need to change dressings daily or even a number of times a day, causing distress to the patient. Topical negative pressure is a method that allows for fewer dressings and provides localized benefits, thus accelerating wound healing. The merits of this therapy have been proven in studies on adults, but research on the pediatric population is scarce. Here we intend to present the results of negative pressure wound therapy (NPWT) on 34 pediatric patients (study group) and compare them with 24 patients (control group) treated with the traditional wet to moist dressing for complicated wounds. The results show that topical negative pressure wound therapy is a safe method that downgrades a wound from a complicated to a simple one and allows definitive coverage using a simpler technique with fewer wound dressings. The scars of the patients in the study group exhibited a better result on a visual scar scale. The patients in the control group had a shorter hospital stay. Based on the recorded results, we were able to make treatment recommendations.

Patho-Anatomic Spectrum of Branchial Cleft Anomalies: Proposal of Novel Classification System.

PURPOSE: Histogenesis, nomenclature, and classification of branchial cleft anomalies (BCAs) have been subjects of controversy for decades. The purpose of this study was to investigate the accuracy of current developmental theories (congenital, lymph node, and hybrid branchial inclusion theories) in defining the anatomic and histopathological characteristics of BCAs. METHODS: Ninety consecutive patients with BCAs who underwent surgical excision were enrolled in this 2-center retrospective cohort study. RESULTS: The present study included 90 patients: 46 (51.11%) women and 44 (48.89%) men (P > .05). The mean age at presentation was 31.89±17.31 years. Altogether, 92 BCAs were identified within the study population including 49 (53.26%) on the left side and 43 (46.74%) on the right side (P > .05). The BCAs included 79 (85.87%) branchial cleft cysts, 11 (11.96%) branchial cleft sinuses, and 2 (2.17%) branchial cleft fistulae. Three (3.26%) BCAs were distributed in the head regions, 88 (95.65%) in the neck regions, and 1 (1.09%) in the thoracic cavity. Following surgery, lymphoepithelial tissue was detected in the histopathological examination in 83 (90.22%) BCAs. The hybrid branchial inclusion theory exhibited significantly higher accuracy in defining patho-anatomic characteristics of BCAs than the branchial apparatus, precervical sinus, thymopharyngeal, and inclusion theories (90.22, 9.78, 2.17, 0.00, and 0.00%; respectively) (P < .05). CONCLUSION: The novel branchial node (BN) classification system based on the hybrid branchial inclusion theory appears to be superior to other classification systems in determining the patho-anatomy of BCAs.

GREB1L, CRELD2 and ITGA10 expression in the human developmental and postnatal kidneys: an immunohistochemical study.

BACKGROUND: Aim of our study is to provide an insight into the genetic expression landscape of GREB1L, ITGA10 and CRELD2 which are important in human genitourinary tract development which might help elucidate the critical stages for the onset of kidney anomalies. METHODS: Morphological parameters were analyzed using immunohistochemistry on human foetal (13-38 w) and postnatal (1.5 and 7.5y) human kidney samples. RESULTS: GREB1L marker had a strong intensity and the highest rate in proximal tubules (PTC) of 1.5 years' kidney (90.25%). In the distal tubules (DCT) there were statistically significant differences in 13 w, 15 w, 16 w, 21 w, 38 w and 7.5y regarding 1.5y (Kruskal-Wallis test, p < 0.001). There was significantly more GREB1L in the glomeruli at 21 w and 38 w in regard to all other stages (Kruskal-Wallis test, p < 0.01). ITGA10 staining intensity was strongest in PCT with the highest rate in 13 w (92.75%), while the lowest rate was found in glomeruli and DCT (Kruskal-Wallis test, p < 0.001). CRELD2 had the strongest staining intensity in PCT with the highest rate in 13 w and 1.5y (92.25%) and lowest in the glomeruli of 7.5 years (24.3 %). In DCT there were statistically significant differences in CRELD2 positive cells in 13 w, 15 w, 16 w, 21 w, 38 w and 7.5y regarding 1.5y (Kruskal-Wallis test, p < 0.01). ITGA10 and CRELD2 co-localised in the postnatal period in DCT. CONCLUSION: High kidney expressions of GREB1L, ITGA10 and CRELD2 even in the postnatal period implicate their importance not only for the onset of CAKUT in the case of their mutation but also for maintenance of kidney homeostasis.

Study of depression and anxiety in patients with asthma and chronic obstructive pulmonary disease.

BACKGROUND: Suggested treatment of patients with COPD and astma requires promotion and psychological dimensions of patients. AIM: Primary objective of this study was to determine frequency of developing anxiety and depression in patients with asthma and chronic obstructive pulmonary disease (COPD) in relation to gender, age and socioeconomic status and to evaluate possible differences between patients with and without high level of anxiety and depression and to find correlation between psychological aspects and disease itself. SUBJECTS AND METHODS: This study included a total of 120 subjects: 60 patients with asthma and 60 patients with COPD. Data were collected using a socio-demographic questionnaire for general information on subjects, standardized Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). RESULTS: Significant difference was found in the anxiety level in these two groups. Average value for the patients with COPD was 43 (15) and for the patients with asthma 37.5 (15.7). Statistically significant difference was also reported for the depression level among females. In female patients with COPD that level was 13.5 (14.7) and in female patients with asthma 7.5 (11). There is a correlation between anxiety and depression in patients with COPD and asthma, especially among women. CONCLUSION: This study suggests that asthma and COPD are a significant stressor with a risk of developing anxiety and depression.

Expression and localization of DAB1 and Reelin during normal human kidney development.

AIM: To explore the spatial and temporal expression patterns of DAB1 and Reelin in the developing and postnatal healthy human kidneys as potential determinants of kidney development. METHODS: Paraffin-embedded fetal kidney tissue between the 13/14th and 38th developmental weeks (dw) and postnatal tissue at 1.5 and 7 years were stained with DAB1 and Reelin antibodies by double immunofluorescence. RESULTS: During the fetal kidney development and postnatal period, DAB1 and Reelin showed specific spatial expression pattern and diverse fluorescence intensity. During the fetal period, DAB1 was strongly expressed in the distal convoluted tubules (DCT), with strong reactivity, and diversely in the proximal convoluted tubules (PCT) and glomeruli. In the postnatal period, DAB1 expression decreased. The strongest Reelin expression in early fetal stages was observed in the PCT. In the postnatal period, Reelin expression decreased dramatically in all observed structures. These two markers were colocalized during early developmental stages, mostly in PCT, DCT, and podocytes. CONCLUSION: The appearance of DAB1 and Reelin during fetal kidney development confirms their potential significant role in the formation of kidney structure or function. High DAB1 expression in the DCT implies its regulatory role in tubular formation or function maintenance during development. Reelin was highly expressed in human kidneys at early fetal stages, mostly in the PCT, while at later fetal stages and postnatal period its expression decreased.

Pain Intensity Scales Comparison in Patient with Abdominal Pain.

BACKGROUND: The aim of study was to explore efficiency of the pain rating scales on patients experiencing abdominal pain, determine correlation between the scales and their applicability to general population and determine the minimal clinical important difference in mm on the VAS as discriminatory for difference in pain intensity. SUBJECTS AND METHODS: The study was performed at the Emergency Department of the University Clinical Hospital of Mostar on patients with abdominal pain which started less than 24 hours before, excluding patients under 16 years old, uncooperative patients and those with altered state of consciousness. The sample data were collected from February to May 2010. Hundred patients completed the questionnaire. Two patients, admitted to the Abdominal Surgery Department, were excluded. The patients were asked to sign the informed consent form and assess the level of pain on three scales (VAS, NRS, VRS). RESULTS: The NRS showed a significant difference in assessing the pain intensity in the observed time. By lapse of time, the patients were reporting lower pain intensity (P=0.017). VAS and NRS had high correlation coefficient values, indicating strong correlation and credibility. The NRS showed strong results correlation (r=0.784; P<0.001). Inter-scale correlation was growing over time. Correlation between VAS and NRS was very strong, the strongest in the last measurement (r=0.950; P<0.001). The NRS correlation with VRS (r=0.430; P<0.001) was slightly better than with VAS (r=0.402; P<0.001). The NRS proved to be the most sensitive to changes in pain intensity (SRM=0.305), whereas the VRS showed extremely low responsiveness (SRM=0.185). CONCLUSION: Having proved as the most useful, reliable and efficient pain assessment instrument, the NRS is hereby recommended as method of pain objectification and determining changes in pain intensity.

Attitudes of Students of Medicine, University of Mostar According to Induced Abortion.

BACKGROUND: Aim of this study was to establish attitudes of medical students on induced abortion and connection of those attitudes with religiousness, length of their studies, sex and various circumstances of pregnancy. SUBJECTS AND METHODS: In total, 148 students of the first, second, fifth and sixth year of medical faculty participated in the research. The study was conducted at the Medical Faculty of the University in Mostar. While collecting the data, we used a survey taken over from literature. The data were tested with adequate statistical methods afterwards. RESULTS: 81.1% of students would perform an abortion under certain circumstances (χ2=57.189; P<0.001). Most students answered that they would perform an abortion in case that a fetus had malformations (χ2=3.892; P=0.49) or if the mother's life were endangered (χ2=47.676; P<0.001). By comparison of students' readiness to perform an abortion under various circumstances of pregnancy depending on length of medical education, statistically significant difference was proved in the following circumstances: rape (χ2=6.097; P=0.014) and if the pregnancy would endanger mother's mental health (χ2=4.488; P=0.034). Students with shorter medical education expressed more liberal attitudes in the above stated circumstances. By comparison of students' readiness to perform an abortion under various circumstances of pregnancy depending on religiousness statistically significant difference was proved in the following circumstances: in case of 'abortion on demand', no matter the reason (χ2=11.908; P=0.012), teenage pregnancy (χ2=33.308; P<0.001) and if the pregnancy would interfere with mother's career χ2=35.897; P<0.001). Unreligious students expressed more liberal attitudes. CONCLUSION: Influence of length of medical education and sex on attitudes on abortion was not proved statistically. Impact of religiousness on that attitude cannot be commented due to very small share of unreligious students in the sample.
