A prenatally detected adrenal cyst treated by adrenal-sparing surgery: case report and review of the literature

A neonatal case of left adrenal cyst detected in utero and successfully treated by adrenal-sparing surgery is presented and discussed with review of the literature. Incidentally discovered prenatal adrenal masses present a diagnostic dilemma. Benign and malignant conditions can present as a fetal suprarenal mass. There is a wide spectrum of management modalities ranging from followup by serial sonographic scanning during pregnancy to early primary excision of the mass. We report a neonate with prenatal diagnosis of a cystic mass arising from the left adrenal gland. Postnatal excision of the mass without adrenalectomy was carried out. Frozen sections of the mass and a biopsy of the left adrenal gland confirmed the benign nature of the cyst and normal adrenal tissue. The uniloculated cyst was reported as a pseudocyst. After surgery, the recovery was uneventful, and the patient was discharged 4 days postoperatively in good condition. On the basis of this case and review of the literature, we may conclude that early primary surgical excision is recommended for either diagnosis or treatment if the results of prenatal or postnatal imaging studies are unreliable for the precise diagnosis of suprarenal mass. Adrenal-sparing surgery is recommended if pathological evaluation of frozen sections has confirmed the benign nature of the mass.Keywords: adrenal-sparing surgery, neonates, prenatal diagnosis, suprarenal cys

Porous metal-organic Cu II complex of L-Arginine; synthesis, characterization, hydrogen storage properties and molecular simulation calculations

Cu II -arginine coordination compound was synthesized and characterized by using DSC, DTA, EA, FT-IR, XRD, SEM and EDX analysis techniques and then the hydrogen storage properties were investigated. Hydrogen storage performance of synthesized compound was determined both experimental and theoretically by using Materials Studio which is one of the Molecular simulation software and adsorption measurement equipment. It is found out that the arginine compound uptakes approximately 1.2 wt. % experimentally and 0.8 wt. % theoretically hydrogen in 77K and 100 bars pressure. Also the surface characteristics was calculated and also the possible cites which could uptake hydrogen in a single lattice cell were determined. At the end of this research, in addition to drug and other applications of L-arginine, it is proved that could be used as a part of adsorbent for hydrogen storage application

The Structural and Thermal Characterization of New Cu-Arginate Complex; Experimental and Simulated Hydrogen Adsorbsition Properties

T he copper-arginate complex was synthesized and characterized by using FTIR, TG/DTA-DrTG, UV-Vis spectroscopy and elemental analysis methods. In addition, experimental and theoretical hydrogen storage capabilities were investigated. The unit cell of complex structure included that one mole CuII as centered cation and one mole of free NaI cation and one mole of NaSO4- as coordinated to arginine ligand and two moles of arginate ligands and one mole of aqua ligand as coordinated to NaSO4-. The CuII cation had square-pyramidal coordination sphere and the Na1 metal cation had trigonal coordination scheme. The other sodium metal cation Na2 was implemented in the released position as counter ion of NaSO4-. It was found that the arginine complex, synthesized in this work have 0.533 m2/g BET surface area and 6.92E-3 wt. % hydrogen storage capacity at 77 K and 1 bar while simulated value was 3.27E-3 wt. % for the same condition

Systematic review of surgical interventions for Crohn's anal fistula

Background Anal fistula occurs in approximately one in three patients with Crohn's disease and is typically managed through a multimodal approach. The optimal surgical therapy is not yet clear. The aim of this systematic review was to identify and assess the literature on surgical treatments of Crohn's anal fistula. Methods A systematic review was conducted that analysed studies relating to surgical treatment of Crohn's anal fistula published on MEDLINE, Embase and Cochrane databases between January 1995 and March 2016. Studies reporting specific outcomes of patients treated for Crohn's anal fistula were included. The primary outcome was fistula healing rate. Bias was assessed using the Cochrane ROBINS‐I and ROB tool as appropriate. Results A total of 1628 citations were reviewed. Sixty‐three studies comprising 1584 patients were ultimately selected in the analyses. There was extensive reporting on the use of setons, advancement flaps and fistula plugs. Randomized trials were available only for stem cells and fistula plugs. There was inconsistency in outcome measures across studies, and a high degree of bias was noted. Conclusion Data describing surgical intervention for Crohn's anal fistula are heterogeneous with a high degree of bias. There is a clear need for standardization of outcomes and description of study cohorts for better understanding of treatment options

Evaluation of nutritional status in pediatric intensive care unit patients: the results of a multicenter, prospective study in Turkey

IntroductionMalnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies.Material and MethodIn this prospective multicenter study, the data was collected over a period of one month from PICUs participating in the PICU Nutrition Study Group in Turkey. Anthropometric data of the patients, calorie intake, 90-day mortality, need for mechanical ventilation, length of hospital stay and length of stay in intensive care unit were recorded and the relationship between these parameters was examined.ResultsOf the 614 patients included in the study, malnutrition was detected in 45.4% of the patients. Enteral feeding was initiated in 40.6% (n = 249) of the patients at day one upon admission to the intensive care unit. In the first 48 h, 86.82% (n = 533) of the patients achieved the target calorie intake, and 81.65% (n = 307) of the 376 patients remaining in the intensive care unit achieved the target calorie intake at the end of one week. The risk of mortality decreased with increasing upper mid-arm circumference and triceps skin fold thickness Z-score (OR = 0.871/0.894; p = 0.027/0.024). The risk of mortality was 2.723 times higher in patients who did not achieve the target calorie intake at first 48 h (p = 0.006) and the risk was 3.829 times higher in patients who did not achieve the target calorie intake at the end of one week (p = 0.001). The risk of mortality decreased with increasing triceps skin fold thickness Z-score (OR = 0.894; p = 0.024).ConclusionTimely and appropriate nutritional support in critically ill patients favorably affects the clinical course. The results of the present study suggest that mortality rate is higher in patients who fail to achieve the target calorie intake at first 48 h and day seven of admission to the intensive care unit. The risk of mortality decreases with increasing triceps skin fold thickness Z-score

Mycoplasma hominis profile in women: Culture, kit, molecular diagnosis, antimicrobial resistance, and treatment

Objectives: Mycoplasma hominis (M.hominis) infections are sexually transmitted and usually associated with urogenital and respiratory diseases. The aim of our study was to (i) detect M. hominis in the vaginal and urine samples of sexually active women using three different detection methods and (ii) to determine the antimicrobial susceptibility and recurrence after the treatment. Methods: Both vaginal and urine samples were collected from 110 sexually active women at the Obstetrics and Gynecology Clinic, Başkent University Ankara Hospital, Turkey, between March 2015 and February 2016. The presence of M. hominis in the vaginal and urine samples was detected by in vitro culture, two biochemical diagnostics kits (Mycoplasma IES (Autobio, China) and Mycoplasma IST–2 (BioMérieux, France) and PCR. The antibiotic susceptibility of each sample was tested using the kits. The women positive for M. hominis were treated either singly or along with their sexual partners by tetracycline. Results: M. hominis was detected in 72 of 220 (32.7%) samples (both vaginal and urine). Of which 37 showed contrary results with two different kits and then were confirmed by PCR. In 13 samples the IES kit identified M. hominis missed by IST-2, and in 8 samples the MIST-2 kit identified M. hominis missed by IES, while both kits missed 6 samples that were agar culture positive for M. hominis.” The highest susceptibility rate was observed against pristinamycin (100%), followed by 91%, 83%, and 75% for doxycycline, tetracycline, and josamycin, respectively. Twenty-five patients treated with tetracycline were followed after one month. The recurrence of M. hominis was not observed in any of the 18 cases where both sexual partners were treated but recurred in 5 of the 7 singly treated women. Conclusions: The rate of M. hominis detection was significantly higher in the vaginal samples compared to the urine samples. The probability of detecting M. hominis by IST–2 kit was 1.18 times less than IES kit (p < 0.001). When the relationship between the samples was examined, the difference between IES and IST–2 for detecting M. hominis was statistically significant (p < 0.01). Antibiotic susceptibility tests indicated that the tetracycline group of antibiotics was effective in eliminating M. hominis when given to both the sexual partners. © 2019 Elsevier LtdFirat University Scientific Research Projects Management Unit Firat University Scientific Research Projects Management UnitThis research was supported by project number 15H0237005 of the Scientific Research Projects Directorate of Ankara University .We thank the doctors and nurse at Baskent University Ankara Hospital for Obstetrics and Gynecology Clinic.
