RESUMEN
OBJECTIVE: Bronchopulmonary dysplasia (BPD) is a leading cause of morbidity and mortality in neonatal intensive care units. Our aim was to evaluate association between packed red blood cell transfusion and the development of BPD in very preterm infants. STUDY DESIGN: This retrospective study of very preterm infants (mean gestational age: 27.1 ± 2.4 weeks, birth weight: 970 ± 271 g) was conducted at Biruni University (Turkey) between July 2016 and December 2020. RESULTS: BPD developed in 107 of the 246 enrolled neonates, including 47 (43.9%), 27 (25.3%), and 33 (30.8%) diagnosed with mild, moderate, and severe BPD, respectively. A total of 728 transfusions were administered. The increased number (4 transfusions [2-7] vs. 1 [1-3], p = 0.001) and volume of transfusions (75 mL/kg volume [40-130] vs. 20 [15-43], p = 0.001) were significantly higher in infants with BPD compared to those without BPD. The transfusion volume cut-off for the prediction of BPD by receiver operating characteristic curve analysis was 42 mL/kg (sensitivity 73.6%; specificity 75%; area under the receiver-operating characteristic curve: 0.82). In multivariate analysis, multiple transfusions and larger transfusion volume were independent risk factors for moderate-severe BPD. CONCLUSION: The increased number and volume of transfusions were associated with BPD in very preterm infants. A packed red blood cell transfusion volume ≥42 mL/kg was a statistically significant predictor of the development of BPD at a postmenstrual age of 36 weeks. KEY POINTS: · Transfusions were found to be an important risk factor for BPD development in very premature infants.. · Number and volume of transfusion were associated with the severity of BPD.. · Optimal cut point volume of transfusion for prediction of BPD was 42 mL/kg body weight..
RESUMEN
Objectives: The association between transient hypothyroxinemia of prematurity (THOP) and metabolic bone disease of prematurity (MBD) is not clearly known. We aimed to evaluate the effects of THOP and other risk factors on MBD in very low birth weight infants. Methods: This study included infants born at <30 weeks gestational age and <1500 g birth weight who were hospitalized between July 2016 and December 2019. The following information was obtained from medical records: Demographic characteristics; clinical follow-up data; morbidities; initial thyroid function tests; and calcium (Ca), phosphorus (P), and alkaline phosphatase (ALP) levels at postnatal 4-6 weeks. Newborns with an ALP level >500 IU/L were diagnosed with MBD. Patients without MBD were defined as Group 1 and patients with MBD were defined as Group 2. Results: Our study enrolled 145 infants who met the inclusion criteria. The incidences of MBD and THOP were 16.5% and 56.5%, respectively. Gestational age and birth weight were significantly lower in Group 2 than in Group 1. It was observed that these infants received total parenteral nutrition for a longer period of time and had a longer transition period to full enteral feeding. In addition, duration of non-invasive mechanical ventilation, duration of oxygen treatment, frequencies of moderate-severe bronchopulmonary dysplasia, and postnatal steroid use were found to be significantly higher in babies in Group 2 compared to babies in Group 1. There was no significant difference between the groups in terms of THOP. However, multivariate logistic regression analysis revealed no risk factors for the development of MBD. The presence of MBD and Ca, P, and ALP levels did not differ significantly between patients with and without THOP. Conclusion: Our study reveals that MBD is a multifactorial disease and THOP is not a risk factor for the development of MBD.
RESUMEN
OBJECTIVE: We aimed to investigate the role of testosterone to estradiol ratio in predicting the effectiveness of human chorionic gonadotropin and testosterone treatments in male hypogonadism. METHODS: Thirty-six male patients with hypogonadotropic hypogonadism were included in the study. Seventeen (47.2%) patients received weekly recombinant human choriogonadotropin alpha (hCG) treatment (group-1) and 19 (52.8%) received testosterone replacement therapy (T treatment) every 21 days (group-2). Under these treatments, adequate frequency of morning erection (≥3/week), testosterone to estradiol ratio (T/E), and testicular volume changes were analyzed. RESULTS: The mean age of the patients was 28.5 ± 8.7 years. When the frequency of morning erection (≥3/week) was specified as adequate, the cut-off value for effective T/E ratio was found to be 12.0 (sensitivity 93.8%, specificity 90.0%). There was no significant difference between the treatment groups in terms of total testosterone levels, T/E ratio, or frequency of morning erections (≥3/week) (p > 0.05). However, there was a statistically significant difference between the groups in terms of median left-right testicular volume in favor of group-1 (p < 0,05). CONCLUSION: In patients with hypogonadism who are under treatment, elevated estradiol-induced erectile dysfunction symptoms may persist even if serum testosterone levels are normal. Testosterone to estradiol ratio can be used as a predictive value in the effective treatment of hypogonadotropic hypogonadism with hCG and T.

In tension gastrothorax, the abdominal contents are displaced into the thorax, leading to a mediastinal shift that arises from the pressure placed on the intrathoracic region. This condition is often due to a congenital or acquired (secondary to surgery) diaphragmatic defect and is rarely seen secondary to trauma. A 40-year-old man presented to the emergency department after an in-vehicle traffic accident. He had no active complaint other than mild chest pain. On auscultation, breath sounds were audible in the left lung base and bowel sounds were heard. Computed tomography of the thorax revealed left-sided diaphragmatic hernia. The jugular vein was distended, and the patient became desaturated in the emergency room. Nasogastric decompression was performed, and the saturation improved. The patient underwent open surgery. Traumatic tension gastrothorax should be considered in the differential diagnosis of acute-onset severe respiratory failure. It can be diagnosed by rapid clinical and radiological evaluation.

Polycystic liver disease (PLD) develops due to embryonic ductal plate malformation of intrahepatic bile ducts. Cysts in the liver can range from a simple compression effect to severe liver failure. The most common complication is rupture and inflammation of cyst. It can sometimes progress to the extent of pushing the heart to the left or compressing the inferior vena cava, thereby reducing the venous return. Here, we present a case with giant liver cyst-related symptoms that caused external compression of the right ventricle and atrium. A 71-year-old female patient was admitted to our emergency department with increasing dyspnea, chest pain, and abdominal distension. Her vital signs were as follows: temperature 38°C, pulse 140 beats/min, and blood pressure 70/40 mmHg. Her abdomen was distended, and there was minimal epigastric tenderness. Hepatomegaly was also present. Posteroanterior chest radiography revealed opacity that erased the right diaphragm contour at the right inferior hemithorax. In thoracoabdominal computed tomography, the heart was deviated toward the left due to the compression of a large cystic formation located in the hepatic right lobe, pushing the diaphragm to the superior. Piperacillin/tazobactam 3 g × 4.5 g treatment was initiated, and external drainage was performed by interventional radiology. Following this procedure, significant improvement was observed in the patient's condition. Her symptoms significantly improved, and the drainage catheter was removed on the seventh day. Hepatic cysts in patients with PLD may compress adjacent structures, and cardiac compression can be life-threatening if hemodynamic instability occurs.
RESUMEN
OBJECTIVES: The perforation of the gallbladder (GP) is one of the most significant complications of acute cholecystitis. A biochemical marker indicating the GP has not been determined fully to date. Pentraxin 3 and pro-adrenomedullin (Pro-ADM) proteins are novel acute phase reactants. We aimed to investigate the relationship between serum Pentraxin 3 and Pro-ADM and the GP in patients with acute cholecystitis. METHODS: This prospective cross-sectional study was conducted on patients with acute cholecystitis in a tertiary care emergency department during the six-month period. The acute cholecystitis patients were divided into two groups as with GP, and without GP. Additionally, patients with GP were evaluated according to pericholecystic fluid and gallbladder wall thickness. Serum levels of pro-ADM and pentraxin 3, WBC, CRP and sedimentation rate were measured in all patients. RESULTS: A total of 60 patients with acute cholecystitis were included in the study. Pro-ADM and pentraxin 3 levels were significantly higher in patients with GP and the with pericholecystic free fluid (pâ¯<â¯0.0001). There was no significant relationship between serum pentraxin 3 and pro-ADM with gallbladder wall thickness (pâ¯>â¯0.05) According to the ROC analysis, serum Pentraxin 3 levels of ≥4.9â¯ng/mL could predict GP with a sensitivity of 75% and a specificity of 85% and serum pro-ADM levels of ≥97â¯nmol/L with sensitivity and specificity of 100% and 95%. CONCLUSION: Our study results reveal that serum Pentraxin 3 and pro-ADM may be novel biochemical parameters in the detection of GP in acute cholecystitis cases.

OBJECTIVE: Uncoupling proteins (UCPs) are carrier proteins located in the mitochondrial inner membrane that disturb the proton gradient by re-transporting protons and that thus inhibit ATP synthesis. UCP-2 is found in in several tissues, particularly the brain. This study was performed to examine the effects of mode of delivery on UCP-2 in humans. METHODS: The study was performed prospectively. Cord blood specimens were collected for measurement of blood gasses, full-blood count, total and direct bilirubin levels and UCP-2. UCP-2 levels were measured using an enzyme-linked immunosorbent assay (ELISA) kit. Results were expressed as nanogram per milliliter. RESULTS: The study was performed with 120 healthy term babies, 60 born by normal spontaneous vaginal delivery (NSVD) and 60 by cesarean/section (C/S). There was significant difference in UCP-2 levels between the two groups. UCP-2 levels were significantly higher in the cases born by NSVD then in the cases born by C/S. CONCLUSION: This study showed that a correlation exists between mode of delivery and UCP-2 in humans. As UCP-2 is described as playing a significant role in the formation of nerve cells and deficiency of this protein during development of the brain may lead to behavioral problems extending to adulthood, we think that increasing UCP-2 levels through normal delivery will protect all organs, and particularly the brain, against oxidative damage and play a role in preventing organ dysfunctions.

OBJECTIVE: To investigate the concentration of vitamin D (VD), glutathione peroxidase (GP), superoxide dismutase (SOD), malondialdehyde (MDA), and advanced oxidation protein products (AOPP) in neonates with hypoxic-ischemic encephalopathy (HIE). MATERIAL AND METHODS: This study was performed prospectively in term neonates treated for HIE. Samples were collected from the neonates in study and control groups at 6-14 h and on day 5 of their lives for 25-OH vitamin D3, antioxidant enzymes including GP and SOD and oxidants substances including MDA and AOPP. RESULTS: This study was performed with 31 term neonates with HIE and 30 healthy term neonates. Maternal VD level was statistically lower in the study group (9.8 ± 6.8 ng/mL) than the control (16.4 ± 8.7 ng/mL) (p = 0.002). SOD and MDA levels were significantly high, and VD level was significantly low in the study group on the first day of life (p = 0.001 and p = 0.028, respectively). SOD and GP levels were significantly high in the study group on day 5 (p < 0.05). VD was significantly low in the study group on day 5 and the proportion of subjects with VD below 5 ng/ml was significantly lower in the control group (p= <0.05). CONCLUSION: VD has neuroprotective and antioxidant properties. We detected VD levels were low in infants with HIE and their mothers. This finding may be useful for decreasing of brain damage.

Trisomy 13 syndrome is a rare disorder that carries a high mortality rate due to abnormal prenatal development resulting in serious birth defects. Although genitourinary malformations are commonly seen in trisomy 13 syndrome, to our knowledge, the association of cloacal exstrophy with trisomy 13 has been extremely rarely reported. Herein, a newborn with trisomy 13 syndrome having multiple congenital anomalies, including cloacal exstrophy, is presented, and the importance of structural anomalies of the neutrophilic leukocytes on a blood smear in supporting diagnosis of trisomy 13 is discussed.
