Does Kangaroo Care Have an Effect on Transition Time from Gavage Feeding to Full Oral Feeding in Premature Babies?

OBJECTIVES: Kangaroo care is a safe and effective alternative method to conventional neonatal care for newborn babies. The aim of this study was to evaluate the effect of kangaroo care on the transition time to full oral feeding in preterm infants fed by gavage. METHODS: This is a randomized controlled trial. This study was conducted in a level III neonatal intensive care unit of a university hospital in eastern Turkey 50 premature babies with a birth weight of≥1000 g and a gestational age of 27-36 weeks, and their mothers were included in the study. The cases were randomly divided into two groups: kangaroo care, which would be applied up to five days a week, and standard care. Records of cases were kept regularly from their hospitalization until they reached full oral feeding. RESULTS: Premature babies in the kangaroo care group reached full oral feeding at 29.20±8.06 days after birth, while babies in the standard care group reached full oral feeding at 44.60±21.90 days. The transition period from gavage feeding to reaching full oral feeding was 13.60±6.83 days in the kangaroo care group, and 22.10±7.38 days in the standard care group. The difference was statistically significant (p=0.007). CONCLUSION: Kangaroo care is an effective method to reduce the transition time from gavage feeding to full oral feeding for premature babies.

Correlation between Perfusion Index and Left Ventricular Output in Healthy Late Preterm Infants.

OBJECTIVE: The perfusion index (PI) is a noninvasive marker derived from photoelectric plethysmographic signals in pulse oximetry in the evaluation of peripheral perfusion. This study was aimed to determine the correlation between PI and left ventricular output (LVO) in healthy late preterm infants at 48th hour of life. STUDY DESIGN: With new generation pulse oximeter (MASIMO Rad 7 Oximeter) pre- and post-ductal PI values were recorded from healthy late preterm babies at the 48th hour of life. PI was determined simultaneously with LVO as measured by transthoracic echocardiography. RESULTS: A total of 50 late preterm babies were included in the study. The mean gestational age of the cases was 35.4 ± 0.7 weeks and the birth weight was 2,586 ± 362 g. Mean pre- and post-ductal PI values at the postnatal 48th hour of babies' life were found to be 2.0 ± 0.9 and 1.7 ± 1.1. The mean LVO value was 438 ± 124, LVO/kg 175 ± 50. When the LVO value was normalized according to the babies' body weight, there was no statistically significant correlation between the pre- and post-ductal PI and the LVO/kg value (r <0.2, p >0.05 in both comparisons). CONCLUSION: There was no correlation between pre- and post-ductal PI and LVO values in healthy late preterm infants. This may be due to the failure of the LVO, a systemic hemodynamic parameter, to accurately reflect microvascular blood flow due to incomplete maturation of the sympathetic nervous system involved in the regulation of peripheral tissue perfusion in preterm babies. KEY POINTS: · No correlation found between PI and LOV in preterm babies.. · LVO cannot adequately reflect peripheral blood flow.. · Sympathetic nervous system is immature in preterm infants..

Transosseous repair with a cortical implant for greater tubercle cyst-related rotator cuff tear results in good clinical outcomes, but significant implant migration.

PURPOSE: To evaluate whether an arthroscopic transosseous technique (ATO) with cortical implants is effective for rotator cuff tear (RCT) repair in patients with cysts of the greater tuberosity (GTC). METHODS: Patients treated with the ATO technique between January 2013 and October 2017 were evaluated. Inclusion criteria were patients treated for both cyst-related and non-cyst-related RCTs and patients with a moderate-sized tear (1-3 cm) according to the DeOrio and Cofield classification. A total of 39 patients were separated into two groups: Group 1 (n = 16) patients with cyst-associated RCT, and Group 2 (n = 23) patients with no cyst. Implant pull-out and migration were evaluated radiologically on standard antero-posterior shoulder radiographs and rotator cuff re-tear was assessed on magnetic resonance images at the final follow-up examination. Group 1 patients were separated into two subgroups according to cyst size (cyst < 5 mm and cyst ≥ 5 mm) and subgroup analysis was performed. Clinical assessment was performed using a visual analog scale, the Constant score and Oxford shoulder score. RESULTS: The mean follow-up time was 33.7 ± 11.7 months. The mean cyst size was 5.4 ± 1.5 mm. There was no significant difference in re-tear rates between the cystic and non-cystic groups. The mean implant migration distance was 3.0 ± 2.2 mm in patients with a RCT -related cyst and 0.7 ± 0.8 mm in those without a cyst. A statistically significant difference was found between the groups (p = 0.002). There was no statistically significant difference between the groups in respect of clinical scores. No implant failure was observed. CONCLUSION: The ATO method performed with a cortical implant in RCTs resulted in satisfactory recovery and clinical outcomes in the short to medium term with low failure rates. While no implant failures were observed, implant migration was associated with cyst presence. Therefore, judicious use is advocated in the choice of transosseous fixation for cyst-related RCTs and patients should be informed of the possibility of implant migration. LEVEL OF EVIDENCE: III.

The Use of the Free Iliac Bone Flap by Shaping Like Puzzle for a Wide Alveolar Defect in a Bilateral Cleft Lip and Palate with Rudimentary Premaxilla.

ABSTRACT: Secondary alveolar bone grafting may not be feasible in a considerable number of patients who have cleft lip and palate, mainly because of the requirement for sizeable bony restitution and the insufficient amount of soft tissue for reliable coverage. Bone transport distraction and free vascularized bone transfers are the salvage techniques for treating these deformities and accomplishing successful bone grafting. This report presents a case of bilateral cleft lip and palate with a large palatoalveolar fistula and a rudimentary premaxilla after prior failed attempts at bone grafting. The authors used the free vascularized iliac bone flap with the osteotomies like puzzle for definitive restoration of the deformity.

[Current State of ERAS Implementation in Thoracic Surgery in Germany]. / Aktuelle ERAS-Implementierung in der Thoraxchirurgie an deutschen Kliniken.

BACKGROUND, OBJECTIVES: In recent years, ERAS treatment pathways have found their way into many surgical fields, as they reduce complications and accelerate postoperative recovery. For thoracic surgery, the first ERAS guidelines were published by the ERAS Society and the European Society of Thoracic Surgeons (ESTS) in 2019. We have now evaluated how ERAS-items are implemented in clinical practice by using an online survey. MATERIAL AND METHODS: An online survey was conducted from 12/5/2021 until 1/6/2021. The survey consisted of 22 questions focusing on the key elements of an ERAS program according to the published ERAS guidelines. Results were summarised, descriptively analysed and put into context with the current literature. RESULTS: Of 155 thoracic surgeons, 32 responded to the survey. In 28.1% (n = 9) of the hospitals, an ERAS core unit was established, and a database to record the ERAS items existed in 15.6% (n = 5). Only 3.1% (n = 1) kept an ERAS-diary preoperatively. A so-called Carboloading was conducted at 15.6% (n = 5) of surgeons. Standard PONV prophylaxis was administered to 59.4% (n = 19) of the patients. In most cases (84.4%, n = 29), a single drain was inserted into the pleural cavity during anatomic resections. In 3% (n = 1) of the centres two drains, in 12.5% (n = 4) no drainage was placed. The most commonly applied initial suction was -10 cmH2O (75%, n = 24). Suction ≤ 2 cmH2O was used by only two of those interviewed. Drainage removal took place in 50% (n = 16) of cases between the 1st or 2nd POD, in 34.4% of cases (n = 11) between the 3rd and 4th POD and in 9.4% (n = 3) the drain remained longer than the 4th POD. The first postoperative mobilisation took place in 71.9% (n = 23) of the centres on the day of the operation. CONCLUSIONS: The implementation of ERAS guidelines varies in Germany between centres. Certain perioperative processes are covered sufficiently, but the implementation of key features of ERAS is yet to be fully established in clinical practice. The first steps in this direction have already been taken and lay the foundation for cooperation across centres.

[The Role of Emergency Departments in Cross-Contamination: The Case of VRE]. / Çapraz Bulasta Acil Servislerin Rolü: VRE Örnegi.

Colonized surfaces, equipment, individuals, and infected patients can be sources for the hospital spread of vancomycin-resistant enterococci (VRE), which is one of the important nosocomial pathogens. The basic epidemiological tools for the prevention and control of hospital-acquired infections are the typing methods. Pulsed-field gel electrophoresis (PFGE) is a highly discriminating method used frequently to detect clonal associations in epidemics and hospital-acquired VRE infections. This study aimed to investigate the presence of cross-contamination, which service or services come to the forefront in case of possible cross-contamination and clonal relationship between VRE strains isolated from rectal swab, clinical and environmental swab samples taken in two different periods in various clinics of Istanbul University Istanbul Medical Faculty Hospital by PFGE method. A total of 125 VREs isolated in two different periods were included in the study. Rectal and environmental swab samples were inoculated on Enterococcosel agar and sodium azide broth, urine samples were inoculated on chromogenic agar, and other clinical samples were inoculated on 5% sheep blood agar and incubated for 18-24 hours. VITEK 2 Compact automation system GP panel (bioMerieux, MarcyL'Etoile, France) was used for the species identification of catalase-negative, gram-positive colonies and disc diffusion and minimum inhibitory concentration (MIC) gradient tests were used to determine vancomycin susceptibility. Multiplex polymerase chain reaction was used to search for vanA and vanB resistance genes in isolates identified as VRE, and PFGE was used to determine clonal association. All isolates were identified as Enterococcus faecium with the vanA resistance gene. It was shown that PFGE clones were divided into six types with 65% similarity (A-F), and in this polyclonal spread, the major type was type A, which contained 108 isolates in 37 subtypes existed in the hospital for years. In patients from whom similar isolates were obtained, the high rate of hospitalizations in the same emergency room or in different emergency services in the same building drew attention. Our results showed that the presence of VRE was established in our hospital, new isolates were added from time to time, and there was a cross-contamination. It was observed that emergency services, where infection control measures were neglected due to working conditions, were among the high-risk areas for VRE contamination. In order to better understand the importance of emergency services in cross-contamination, it would be useful to conduct surveillance studies among patients hospitalized in emergency services and monitor the rate of VRE in the services where positive patients were transferred.

The Effect of Intravesical Prostatic Protrusion in Patients with Benign Prostatic Hyperplasia: Controlled, Clinical Study.

BACKGROUND: Although prostate cancer releases more prostate-specific antigen (PSA) per unit of prostate volume (PV), data are limited regarding the association between intravesical prostatic protrusion (IPP) and the PSA level. OBJECTIVES: The study aim was to evaluate the IPP effect in patients with benign prostatic hyperplasia. METHOD: This study included patients with (n = 119) and without (n = 121) IPP. The age, International Prostate Symptom Score (IPSS), PSA level, maximum and average flow rates, PV, hematuria, urinary retention, and post-void residual (PVR) volume were compared between the 2 groups. RESULTS: The mean ages were similar between the 2 groups (66.56 ± 8.67 and 66.92 ± 8.7 years, respectively, p = 0.747), and there were no statistically significant differences in the IPSS, maximum and average flow rates, hematuria, PVR volume, and urinary retention means (p > 0.05). However, the IPP patients had lower total PSA (tPSA) and free PSA (fPSA) levels than those without IPP (3.55 [4.18] vs. 5.26 [5.24] ng/mL, p = 0.013 and 0.7 [1.09] vs. 1.05 [1.23] ng/mL, p = 0.029, respectively). Moreover, there were strong positive correlations between the IPP grade and the tPSA and fPSA levels (r = 0.262, p = 0.001 and r = 0.254, p = 0.002 respectively). CONCLUSIONS: This study demonstrated that IPP results in a decreased PSA level, even with a higher PV.

Effects of varicocele on testicles: Value of strain elastography: A prospective controlled study.

The aim of this study was to evaluate the structural changes in testicles of the patients with varicocele by strain elastography (SE) and to identify the relationship between semen analysis and hormone levels considering SE results. The patients were separated into two groups as varicocele and control, according to their physical examination and the scrotal colour duplex ultrasonography results. All patients underwent examination by hormonal profile, semen analysis, colour duplex ultrasonography and sonoelastography. Testicular volume, resistive index (RI) of intratesticular arterial flow, strain rate and varicocele measurements were recorded. The left testicle strain ratios (SR) median value was 0.18 (0.15-0.26) in the varicocele group and 0.25 (0.19-0.28) in the control group (p < 0.001). The median RI value was 0.59 (0.52-0.64) in the varicocele group and 0.52 (0.5-0.59) in the control group (p < 0.001). No difference was found considering volume between the right and left testicles in either group. These results showed that elastography could be useful to detect the damage caused by varicocele on testicles in early period. However, studies with more patients would help to increase elastography's value and reliability.

Does transrectal ultrasonography-guided biopsy of the prostate lead to possible further metastasis via circulating tumor cells?

Background/aim: We evaluate whether transrectal ultrasonography (TRUS)-guided prostate biopsy might lead to spillage of tumor cells into peripheral blood as a result of disruption of the epithelial barrier and ultimately result in metastasis. Materials and methods: Eighty-eight patients underwent TRUS-guided prostate needle biopsy due to prostate-specific antigen (PSA) increase or abnormal digital rectal examination at the Samsun Research and Training Hospital (Samsun, Turkey) between April 2016 and September 2018. Approximately 10 mL of whole blood was collected from patients before, 1 week after, and 1 month after biopsy. Samples were analyzed for CD117 positivity and prostate-specific membrane antigen (PSMA) levels using flow cytometry. Patients with pathologically determined prostate cancer and without CD117 positivity before biopsy were included in the study. The study group thus consisted of 55 patients. Results: Subjects' PSA levels ranged from 2.3 to 40.0 ng/mL (median: 7.9 ng/mL), and their Gleason score was a median of 7 (range: 5­9). PSMA levels ranged between 9.3 ng/mL and 118.5 ng/mL and CD117 antigen levels between 0 and 5. We detected no CD117- positive cells in blood samples collected 7 days or 1 month after biopsy. Conclusion: We detected no circulating tumor cells in the peripheral circulation following biopsy. Prostate needle biopsy seems to be a safe method in terms of spillage of tumor cells into blood circulation as a possible cause of further metastasis.

Psychometric findings and normative values for the CLEFT-Q based on 2434 children and young adult patients with cleft lip and/or palate from 12 countries.

BACKGROUND: Patients with cleft lip and/or palate can undergo numerous procedures to improve appearance, speech, dentition and hearing. We developed a cleft-specific patient-reported outcome instrument to facilitate rigorous international measurement and benchmarking. METHODS: Data were collected from patients aged 8-29 years with cleft lip and/or palate at 30 hospitals in 12 countries between October 2014 and November 2016. Rasch measurement theory analysis was used to refine the scales and to examine reliability and validity. Normative CLEFT-Q values were computed for age, sex and cleft type. RESULTS: Analysis led to the refinement of an eating and drinking checklist and 12 scales measuring appearance (of the face, nose, nostrils, teeth, lips, jaws and cleft lip scar), health-related quality of life (psychological, social, school, speech distress) and speech function. All scales met the requirements of the Rasch model. Analysis to explore differential item functioning by age, sex and country provided evidence to support the use of a common scoring algorithm for each scale for international use. Lower (worse) scores on CLEFT-Q scales were associated with having a speech problem, being unhappy with facial appearance, and needing future cleft-related treatments, providing evidence of construct validity. Normative values for age, sex and cleft type showed poorer outcomes associated with older age, female sex and having a visible cleft. INTERPRETATION: The CLEFT-Q represents a rigorously developed instrument that can be used internationally to collect and compare evidence-based outcomes data from patients aged 8-29 years of age with cleft lip and/or palate.

Clinical features of children with multicystic dysplastic kidney.

BACKGROUND: To evaluate the clinical features of patients with multicystic dysplastic kidney (MCDK). METHODS: The medical files of children diagnosed with MCDK between January 2008 and November 2015 were retrospectively reviewed. The demographic, clinical, laboratory and radiological data were evaluated. RESULTS: Of 128 children with MCDK enrolled in the study, 82 (64.1%) were male, and 46 (35.9%) were female (P < 0.05). MCDK were located on left and right sides in 66 (51.6%) and 62 children (48.4%), respectively (P > 0.05). Antenatal diagnosis was present in 64 patients (50%). The mean age at diagnosis was 2.8 ± 2.7 years (range, 0-8 years), and follow-up duration was 4.5 years. Fifteen patients (20.8%) had vesicoureteral reflux. Of these, four underwent endoscopic surgical correction. Other associated urological anomalies were ureteropelvic junction obstruction (n = 6), hypospadias (n = 1), and kidney stones (n = 1). On technetium-99 m dimercaptosuccinic acid scintigraphy, which was performed in all patients, no significant association between grade of reflux and presence of scarring was seen. Hypertension was diagnosed only in one child (0.8%) who required antihypertensive treatment. The prevalence of unilateral undescended testicle in children aged <1 year in the 82 male patients was 4.9%. Seventy-six patients (59.4%) developed compensatory hypertrophy in the contralateral kidney during a 1 year follow-up period. Of the total, only seven children (5.5%) had undergone nephrectomy. CONCLUSIONS: MCDK follows a benign course with relatively few sequelae, and therefore these patients should be closely followed up and conservatively managed.

Risk factors for complex regional pain syndrome in patients with surgically treated traumatic injuries attending hand therapy.

STUDY DESIGN: Prospective cohort study. INTRODUCTION: Identification of risk factors for CRPS development in patients with surgically treated traumatic injuries attending hand therapy allows to watch at-risk patients more closely for early diagnosis and to take precautionary measures as required. PURPOSE OF THE STUDY: The aim of this study was to evaluate the risk factors for the development of complex regional pain syndrome (CRPS) after surgical treatment of traumatic hand injuries. METHODS: In this prospective cohort, 291 patients with traumatic hand injuries were evaluated 3 days after surgery and monitored for 3 months for the development of CRPS. The factors assessed for the development of CRPS were age, sex, manual work, postoperative pain within 3 days measured on a Pain Numerical Rating Scale (0-10), and injury type (crush injury, blunt trauma, and cut laceration injury). RESULTS: CRPS was diagnosed in 68 patients (26.2 %) with a duration of 40.10 ± 17.01 days between the surgery and CRPS diagnosis. The mean postoperative pain score was greater in patients with CRPS than in those without CRPS (P < .001). Patients with pain scores ≥ 5 had a high risk of developing CRPS compared with patients with pain scores <5 (odds ratio: 3.61, confidence interval = 1.94-6.70). Patients with crush injuries were more likely to develop CRPS (odds ratio: 4.74, confidence interval = 2.29-9.80). CONCLUSIONS: The patients with a pain score of ≥5 in the first 3 days after surgery and the patients with crush injury were at high risk for CRPS development after surgical treatment of traumatic hand injuries. LEVEL OF EVIDENCE: II b.

Rehabilitation of the Work Accident-Related Traumatic Mandible With Iliac Free Flap, Distraction Osteogenesis, and Dental Implants.

Mandibular bone defects due to extensive trauma impair occlusion and affect the aesthetics of facial contouring, making it difficult to obtain a satisfactory outcome. Distraction osteogenesis and free flap is an effective and aesthetic treatment option for rehabilating these defects. In this clinical report, the authors present rehabilitation of a wide mandibular traumatic defect due to a work-related accident with iliac free flap, distraction osteogenesis, and dental implants.

Recent changes in the features of hypertrophic pyloric stenosis.

BACKGROUND: Hypertrophic pyloric stenosis (HPS) is a rare cause of non-bilious vomiting in young infants; the condition requires surgical management. Diagnosis is based on clinical, laboratory, and radiological findings. In the present study, we evaluate recent changes in the features of HPS. METHOD: We retrospectively reviewed the demographic, clinical, and laboratory data on 56 HPS patients who underwent pyloromyotomy between 1996 and 2015. Patients were divided into two groups according to date of operation (group 1, 1996-2006; group 2, 2007-2015). RESULTS: Group 1 consisted of 30 patients and group 2, 26. The age at diagnosis was longer in group 2 (43.3 ± 13.1 days) than group 1 (37.4 ± 17.7 days). All diagnoses were confirmed on ultrasonography. Pyloromyotomy was performed on all 56 patients (48 boys, 8 girls). Significant between-group differences were evident in terms of age at onset of vomiting; rate of dehydration; development of palpable olive-shaped abdominal mass; serum urea and creatinine; acid-base status; and air distribution pattern on abdominal radiography (all P < 0.05). CONCLUSION: The frequency of olive-shaped abdominal mass evident on physical examination decreased significantly over time, and was lower than published values. Early diagnosis triggers timely support and surgical intervention, and may thus prevent development of the classical clinical and laboratory findings of late-stage HPS. The remarkable recent advances in ultrasonography and techniques allow HPS to be diagnosed earlier than formerly.

The efficacy of udenafil in end-stage renal disease patients undergoing hemodialysis.

INTRODUCTION: Erectile dysfunction (ED) is frequently observed in end-stage renal disease (ESRD) patients on hemodialysis (HD) compared to non-uremic patients. This situation causes severe psychogenic problems in patients and disrupts the quality of life. Different phosphodiesterase type 5 (PDE-5) inhibitors have been used, and efficacies revealed, for the treatment of ED in HD patients; however, there are no studies related to udenafil use or results for HD patients. This study retrospectively evaluated the efficacy and reliability of udenafil for HD patients. MATERIALS AND METHODS: The laboratory findings, side effects after treatment, and International Index of Erectile Function (IIEF) scores before and after treatment were compared and evaluated for HD patients who applied to our urology clinic with ED complaints and were treated with udenafil. RESULTS: The results showed that in the HD patient group with ED, apart from ED, there were severe rates of other sexual dysfunction. In our patient group, there was a statistically significant improvement in all scores for erectile function (p = 0.033), orgasmic function (p < 0.001), sexual desire (p < 0.001), relationship satisfaction (p < 0.001), and general satisfaction (p < 0.001) after treatment. The reported side effects were headache in one patient and dyspepsia in one patient. CONCLUSION: We concluded that udenafil is an effective and reliable treatment approach for HD patients; however, our results require support from prospective randomized crossover studies with sildenafil.

Unilateral Le Fort I Osteotomy for Rehabilitating the Large Alveolar Cleft and Vertical Malocclusion With the Distraction Technique.

Rehabilitation of the large alveolar clefts with autogenous graft or distraction osteogenesis is one of the most common treatment choices. Depending on the clinical situation such as vertical deficiencies, linear transport of the segment does not always ensure a proper closure of the cleft space. In this report, the authors present a patient in whom large unilateral cleft and vertical alveolar deficiency were closed by unilateral Le Fort I osteotomy and distraction technique using the orthodontic elastics.

Serial Presurgical Orthopedics for Eye Repositioning and Optimization of Soft-Tissue Repair in an Infant With Tessier No. 4 Cleft.

OBJECTIVE: A male patient with Tessier No. 4 cleft (unilateral left) presented at 20 days of age. The cleft defect beginning between the cupid bow and oral commissure extended to the ipsilateral orbital floor, skirting the nose and lacrimal duct while passing through the cheek medial to the infraorbital nerve. With the lesser segment disposed 16 mm transversely, the wide gap included an absence of orbital floor and lower eyelid. A deficient midfacial platform caused a severe inferior globe dystopia, superiorly displaced left ala base, and severe vertical shortening between ala-canthus and ala-globe. INTERVENTION: A modified Latham device applied directional orthopedics to contract the cleft gap and with an eye part added to elevate the dystopic globe. Two different Latham devices used in succession were each applied for 4 weeks. Lastly, a removable plate further repositioned the eye. Each appliance was designed to differentially move the noncleft and cleft segments of the maxilla. Presurgical orthopedics began at 3 weeks lasted 14 weeks. Intraoperatively at 17 weeks, the inferior globe dystopia was effectively reduced, and the cleft gaps were nearly closed and aligned at the orbital floor, cheek, and the alveolus. Respecting the aesthetic units of face became possible with the soft-tissue repair yet were tight enough in the malar region to retract the lower lid. CONCLUSION: The presurgical directional orthopedic and eye-globe mechanics were sufficient to enable medial canthal repositioning, sustainable correction of orbital distopia, and optimized primary soft-tissue repair. Early result suggests that surgery with presurgical orthopedics is superior to surgery alone.

Neonatal Jaundice Detection System.

Neonatal jaundice is a common condition that occurs in newborn infants in the first week of life. Today, techniques used for detection are required blood samples and other clinical testing with special equipment. The aim of this study is creating a non-invasive system to control and to detect the jaundice periodically and helping doctors for early diagnosis. In this work, first, a patient group which is consisted from jaundiced babies and a control group which is consisted from healthy babies are prepared, then between 24 and 48 h after birth, 40 jaundiced and 40 healthy newborns are chosen. Second, advanced image processing techniques are used on the images which are taken with a standard smartphone and the color calibration card. Segmentation, pixel similarity and white balancing methods are used as image processing techniques and RGB values and pixels' important information are obtained exactly. Third, during feature extraction stage, with using colormap transformations and feature calculation, comparisons are done in RGB plane between color change values and the 8-color calibration card which is specially designed. Finally, in the bilirubin level estimation stage, kNN and SVR machine learning regressions are used on the dataset which are obtained from feature extraction. At the end of the process, when the control group is based on for comparisons, jaundice is succesfully detected for 40 jaundiced infants and the success rate is 85 %. Obtained bilirubin estimation results are consisted with bilirubin results which are obtained from the standard blood test and the compliance rate is 85 %.

Preputial bacterial colonisation in uncircumcised male children: Is it related to phimosis?

OBJECTIVE: To evaluate the presence of uropathogens in the periurethral skin and the effect of phimosis on bacterial colonisation. METHODS: The observational cohort study was conducted in Samsun Research and Training Hospital, Samsun, Turkey from June to December, 2014, and comprised patients undergoing circumcision. Before circumcision, all children were examined in the operating room and the presence of phimosis was recorded. All patients had circumcision performed by the same surgical team under general anaesthesia. Before the procedure, samples were taken from preputial skin of all patients by swab before cleansing with polyvidone-iodine. The samples were inoculated on 5% sheep blood agar and eosin-methylene blue agar. RESULTS: The median age of the 117 children was 5 years (range: 1-12). Of the total, 19(16.2%) children had complete phimosis, and 72(61.5%) had partial phimosis. In all,91(77.7%) children had phimosis and 26(22.3%) had no phimosis. Of the 91 patients with different degrees of phimosis, 52(57.1%) had clinically significant uropathogenic bacterial colonisation >100,000 colony-forming units per millilitre [cfu/ml]). Of the 26 patients without phimosis, 13(50%) had clinically significant colonisation. Thus, there was no effect of the presence of phimosis on bacteria colonisation (p=0.655). CONCLUSIONS: Important uropathogens colonise the preputium in uncircumcised male children. There was no effect of phimosis on colonisation.

Incidence of bacterial colonisation after indwelling of double-J ureteral stent.

OBJECTIVE: To determine the bacterial colonisation after double-J stent use and the risk factors for bacteriuria linked to the stent. MATERIALS AND METHODS: A total of 102 patients (61 men and 41 women, mean age 47.5 ± 14.16) were examined. The stents were removed under aseptic conditions, and a urine culture was obtained before the removal of the stents. After the stents were removed, the upper, central and lower sections were separated, and washing water was sent through the stent. RESULTS: Bacterial colonisation was found in 29.4% (30 of 102) of the stents. The most frequently observed microorganisms were determined as staphylococcus, coagulase negative (8 of 30) and E. coli (5 of 30). The washing fluid used to clean the interior of the catheter produced pathogens in 8 patients (7.8%), and these pathogens were observed to be the same microorganisms that colonised the outside of the stent. There was no statistical difference between the patients with colonisation and those without in terms of age, gender, duration of stenting and reason for stent insertion. CONCLUSIONS: Though stent colonisation does not always entail symptomatic urinary tract infections, as shown in our study, the pathogens in the urine culture are the same as those colonising the stent, confirming the reality that colonisation is the main factor in these events. Additionally, according to our study, significant colonisation may be found in the first 3 weeks, contrary to the literature, causing us to consider that urinary tract infections may develop even in the early period.
