Catheter-related Saccharomyces cerevisiae Fungemia Following Saccharomyces boulardii Probiotic Treatment: In a child in intensive care unit and review of the literature

Although Saccharomyces boulardii is usually a non-pathogenic fungus, in rare occasions it can cause invasive infection in children. We present the case of an 8-year-old patient in pediatric surgical intensive care unit who developed S. cerevisiae fungemia following probiotic treatment containing S. boulardii. Caspofungin was not effective in this case and he was treated with amphotericin B. We want to emphasize that physicians should be careful about probiotic usage in critically ill patients.

The effect of dorsal dartos flaps on complication rates in hypospadias repair: A randomised prospective study

AIM This study prospectively analysed the effect of using a dartos flap on the complication rates of TIPU (tubularised incised plate urethroplasty) in hypospadias repair. MATERIAL AND METHODS Patients having TIPU repair for hypospadias at our university hospital between January 2010 and August 2013 were prospectively divided into two groups. Group 1 had TIPU repair with dorsal dartos flap, whereas group 2 had flapless repair. At the end of the follow-up period (mean 23.3 m, median 20.2), complication rates were compared between two groups. RESULTS There were 107 patients in each group. The overall complication rate was 9.3%. The complication rates were 12.1% in group 1 (6 glans dehiscence and 7 fistula) and 6.5% in group 2 (2 glans dehiscence and 5 fistula). The differences between complication rates and fistula were statistically insignificant (p = 0.2511 and p = 0.7710, respectively). CONCLUSION Our prospective and randomised study found that the use of dartos flaps in hypospadias offers no statistically significant advantage over flapless repair for complication rates.

The antifibrotic drug halofuginone reduces ischemia/reperfusion-induced oxidative renal damage in rats

AIM The objective of the present study was to evaluate the protective effects of halofuginone against renal ischemia/reperfusion (I/R) injury. MATERIALS AND METHODS Male Wistar albino rats were unilaterally nephrectomized and the left renal pedicles were occluded for 45 min to induce ischemia and then reperfused for 6 h (early) or for 72 h (late). The rats were treated intraperitoneally with either halofuginone (100 μg/kg/day) or saline 30 min prior to ischemia and the dose was repeated in the late reperfusion groups. In the sham groups, rats underwent unilateral nephrectomy and were treated at similar time points. The animals were decapitated at either 6 h or 72 h of reperfusion and trunk blood and kidney samples were obtained. RESULTS I/R injury increased renal malondialdehyde levels, myeloperoxidase activity and reactive oxygen radical levels, and decreased the renal glutathione content. Halofuginone treatment was found to reduce oxidative I/R injury and improve renal function in the rat kidney, as evidenced by reduced generation of reactive oxygen species, depressed lipid peroxidation and myeloperoxidase activity, and increased glutathione levels. CONCLUSIONS The present findings demonstrate the anti-inflammatory and antioxidant effects of halofuginone in renal I/R injury, supporting its potential use where renal I/R injury is inevitable.

Lactococcus lactis Catherter-Related Bloodstream Infection in an Infant: Case Report

Lactococcus lactis is a gram-positive coccus that is nonpathogenic in humans. Herein, we present the case of a 1-year-old boy with Down syndrome and Hirschprungs disease (HD) who developed a catheter-related bloodstream infection with L. lactis after gastrointestinal surgery. The patient had been hospitalized in the pediatric surgery unit from birth because of HD, and had undergone the Duhamel-Martin procedure which caused recurrent diarrhea episodes and feeding intolerance. On the infants 430th day of life, he had an episode of gastroenteritis and feeding intolerance. Because of clinical suspiction of sepsis, blood cultures were taken both from the central venous catheter and peripheral vein, and evidence of a growing microorganism was detected in 2 different central venous catheter blood cultures taken 2 days apart. The colonies were then identified by both the Vitek 2 and Vitek MS systems (bioMérieux, Marseille, France) as L. lactis spp. lactis. The central venous catheter could not be removed because of the absence of a peripheral venous line, and the patient was subsequently successfully treated with vancomycin. Therefore, although Lactococcus species is generally thought to be nonpathogenic, it should still be kept in mind as a potential pathogen in infants.

Halofuginone Alleviates Burn-Induced Hepatic and Renal Damage in Rats.

The aim of this study was to evaluate the possible protective effects of halofuginone on burn-induced oxidative injury of the liver and kidney. For the induction of burn, backs of Wistar albino rats were shaved and exposed for 10 seconds to water bath at 90°C, whereas rats in the control group were exposed for 10 seconds at 25°C. Rats were then administered either saline (1 ml/kg) or halofuginone (100 &mgr;g/kg/day) intraperitoneally and decapitated at the 24th hour (early burn) or on the 7th day (late burn). Serum concentrations of creatinine, blood urea nitrogen, alanine aminotransferase, and aspartate aminotransferase were determined. Renal and hepatic tissue samples were used for microscopic analysis, and glutathione, malondialdehyde, and myeloperoxidase activity and chemiluminescence levels were measured. Halofuginone treatment improved renal functions in late burn group and hepatic functions in early burn group as demonstrated by decreased serum creatinine, blood urea nitrogen, and alanine aminotransferase levels. Increased serum lactate dehydrogenase level measured in late phase was reduced by halofuginone treatment. Generation of reactive oxygen metabolites measured by chemiluminescence, indicating burn-induced renal and hepatic oxidative injury in both the early and late burn groups, was reduced by halofuginone. Increased hepatic malondialdehyde levels accompanied with high microscopic damage scores were reversed by halofuginone in early burn group, while depleted renal glutathione levels were replenished. The present findings demonstrate that halofuginone preserved renal and hepatic functions and alleviated oxidative tissue damage insulted by burn trauma, suggesting an anti-inflammatory and antioxidant potential for halofuginone in providing protection against burn-induced renal and hepatic injury.

A Case of Acute Myeloid Leukemia (FAB M2) with Inversion 16 Who Presented with Pelvic Myeloid Sarcoma.

Acute leukemias are the most common childhood cancer in all age groups. Acute myeloid leukemias (AML) constitute about 15–20% of acute leukemias. Fatigability, pallor, fever, and bleeding are the most common presenting symptoms of AML. Hepatosplenomegaly and lymphadenopathy are commonly encountered during physical examination. In rare instances eruptions due to skin involvement and localized tumor masses (myeloid sarcoma) may be found. Myeloid sarcoma is especially seen in AML-M2 subtype. By cytogenetic analysis, in AML-M2 subtype t(8;21) is often seen and it is more probable to find inversion 16 in AML-M4Eos subtype. Herein, we present a 15-year-old girl whose initial symptom was abdominal pain for three days and her pathological sign was a large abdominal mass which was verified by imaging studies and diagnosed as myeloid sarcoma by biopsy. On bone marrow examination, she had diagnosis of AML-M2 and by cytogenetic analysis inversion 16 was positive. She was treated with AML-BFM 2004 protocol and she is being followed up in remission on her ninth month of the maintenance therapy.

The effectiveness of non-operative treatment in high-grade liver and spleen injury

BACKGROUND Although a nonoperative treatment approach is preferred for blunt liver and spleen trauma in childhood, there are significant differences between clinics in the algorithms used. The approach to high-grade liver and spleen injury is still controversial, particularly as grade V liver and spleen injuries are not included in the American Pediatric Surgical Association guideline. The aim of this study was to present experience with a non-operative treatment approach to children with high-grade liver and spleen injuries. METHODS Pediatric patients who were referred to Marmara University Hospitals emergency department between January 2012 and January 2017 due to liver and spleen injury related to blunt abdominal trauma and who were followed up in the clinic were included in the study. The data were analyzed retrospectively in terms of age, sex, type of trauma, degree of organ damage, accompanying organ damage, duration of intensive care unit (ICU) and hospital stay, need for transfusion, and treatment method (operative-nonoperative). Grade I, II, or III organ damage was classified as low-grade, while grade IV and V organ lesions were classified as high-grade. RESULTS Of 2800 patients who were diagnosed by radiological imaging with liver and spleen injuries due to blunt abdominal trauma and hospitalized in the clinic, 88 were included in the study. Isolated liver injury was determined in 41 patients, while 39 had an isolated spleen injury, and 8 had injuries to both organs. An accompanying organ injury was observed in 30 (34%) patients. In all, 83 (94%) patients underwent non-operative treatment and a surgical approach was required for 5 patients (6%). Patients with high-grade liver injury had a significantly longer period of hospitalization, duration of ICU stay, and greater transfusion requirement, compared with patients with low-grade liver injury (p=0.001, 0.001, and 0.001, respectively). A surgical approach was more common among patients with a highgrade liver injury than for patients with a low-grade injury (p=0.045). There was no significant difference between patients with a high- or low-grade spleen injury in terms of age, sex, duration of hospitalization, duration of ICU stay, transfusion requirement, or accompanying organ injury (p=0.254, 0.739, 0.114, 0.135, 0.057, 0.721, respectively). Similarly, there was no significant difference in terms of non-surgical or surgical treatment approach between the patients with high-grade spleen injury and those with low-grade spleen injury (p=0.488). CONCLUSION Non-operative treatment is a feasible treatment method in pediatric patients with a high-grade blunt liver or spleen injury. Nonetheless, pediatric surgeons should bear in mind that patients with high-grade liver damage may require more surgical treatment.

Is an interval appendectomy still necessary in perforated appendicitis with inflammatory mass/abcess

We reviewed our experience in non-operative management without an interval appendectomy (IA), for patients who presented with perforated appendicitis with an abcess or inflammatory mass from November 2012 to November 2017 retrospectively. The data included age, sex, duration of symptoms, presence of appendicolith/ abcess on CT imaging, WBC and CRP levels, antibiotic treatment, fever at presentation, percutan drainage procedure and complications, recurrent abscess, total length of hospitalization, follow-up period. A total of 32 patients were treated with nonoperative management during the study period. Nonoperative management without an IA was successful in 31 patients (96%). Study patients included were admitted to the surgical ward for observation. The mean age of the patients was 9.74±3.55 years. 19 male and 13 female patients were included in the study. The mean duration of symptoms was 8.75±4.69 days. The mean number of Ct scans was 1.21±0.42 per patient. Percutan drainage was performed in 10 patients. The mean of WBC levels at presentation was 19030.00±7192.24 cells/μL and CRP levels was 156.61±94.23 mg/dl. Intravenous piperacillin-tazobactam (Tazosin®, Pfizer, New York, NY) were given 400 mg/kg/day in four divided doses. Diet were started to the patients who were afebrile and had diminished abdominal pain during observation. The mean length of hospitalization was 13.03±5.82 days. The mean duration of follow-up period 34.65±20.48 months. Nonoperative management without IA is a preferable choice for perforated appendicitis with abcess or mass.

Inguinal Hernia Containing Uterus, Fallopian Tube, and Ovary in a Premature Newborn.

A female infant weighing 2,200 g was delivered at 34 weeks of gestation by vaginal delivery. She presented with an irreducible mass in the left inguinal region at 32 days of age. An ultrasonography (US) was performed and an incarcerated hernia containing uterus, fallopian tube, and ovary was diagnosed preoperatively. Surgery was performed through an inguinal approach; the uterus, fallopian tube, and ovary were found in the hernia sac. High ligation and an additional repair of the internal inguinal ring were performed. Patent processus vaginalis was found during contralateral exploration and also closed. The postoperative course was uneventful. After one year of follow-up, there have been no signs of recurrence.
