Use of autologous blood patch for prolonged air leak in spontaneous pneumothoraces in the adolescent population.

Instillation of an autologous blood patch for prolonged air leak (PAL) in chest tube system has been studied and determined to be a safe and effective treatment plan for adults. The current recommended treatment guidelines for a PAL in adolescent secondary to a spontaneous pneumothorax are surgical intervention. This paper serves as documentation of two case reports with successful treatment of PALs with autologous blood patch in two adolescent patients.

The impact of vesicoureteral reflux treatment on the incidence of urinary tract infection.

Vesicoureteral reflux (VUR) is a heterogeneous disease and its management remains one of the most controversial topics in pediatrics. Management options include surveillance, antibiotics, and surgery. The approval of dextranomer/hyaluronic acid (DHA) as a bulking agent by the Food and Drug Administration was followed by wide acceptance of endoscopic techniques as a major tool in the management of reflux. Pyelonephritis rather than VUR is the most common cause of kidney damage in children. It should be emphasized that the primary goal of diagnosing and treating VUR should be preventing this complication. There are no sufficient data in the literature to address the impact of the different treatment modalities on the incidence of febrile urinary tract infections (feb-UTIs) denoting pyelonephritis, with very few studies evaluating endoscopic treatment in light of this clear and well-defined outcome. The fact that we can correct the anatomy at the vesicoureteral junction with a simple and relatively safe outpatient procedure does not justify offering it to all patients. In this review, we attempt to critically evaluate the available literature pertaining to the impact of different treatment modalities on reducing the incidence of febrile UTIs and kidney damage, with a special emphasis on endoscopic treatment.

Improving tactile sensation in minimally invasive pediatric surgery.

PURPOSE: The aim of this study was to investigate factors that impact tactile sensation during minimally invasive pediatric surgery. METHODS: Three different 3-mm Maryland laparoscopic instruments were tested with and without the resistance of a trocar (Ethicon 3-mm): Jarit (24-cm shaft, 113 g), Storz (30-cm shaft, 62 g), and an ultra-light prototype (24-cm shaft, 5 g). Experiments were conducted in a custom-designed laparoscopic simulator that directs instruments at fixed angles toward a central target. Surgeons were instructed to insert the instruments into the simulator and make contact with the target with as little force as possible. Instantaneous pressure measurements on the target were measured and recorded every 0.0001 seconds. The differences between impact pressures were compared with a paired, two-tailed, Student's t test. RESULTS: Twenty-seven (27) surgeons participated in the study. The ultra-light prototype had significantly lower impact pressures than the Storz instrument at all angles both with a trocar (P < 0.05) and without a trocar (P < 0.001). The ultra-light prototype had significantly lower impact pressures than the Jarit instrument at all angles in the absence of a trocar (P < 0.001), but with a trocar in place the only significant difference was at 5 degrees (P < 0.001). The presence of the trocar on the ultra-light prototype had a negative impact on tactile sensation that was statistically significant (P < 0.01). CONCLUSIONS: The presence of a trocar negatively impacted the surgeon's tactile sensation. Decreasing instrument mass by 10- to 20 fold did make a statistically significant improvement in tactile sensation.

The deflux procedure reduces the incidence of urinary tract infections in patients with vesicoureteral reflux.

PURPOSE: The aim of this study was to review the experience of a single institution with the Deflux (Q-Med Scandinavia; Uppsala, Sweden) procedure and assess its effectiveness in reducing the incidence of urinary tract infections (UTIs) in children with vesicoureteric reflux (VUR). MATERIALS AND METHODS: After institutional review board approval, the charts of 100 patients with VUR, who presented between June 2003 and June 2005, were prospectively reviewed. Data collected included: demographics, the number of preoperative and postoperative UTIs, a radiologic grade of VUR on a voiding cystourethrogram (VCUG) and the presence of VUR on a radionuclide VCUG 3 months after the procedure. Patients were continued on oral antibiotics until urine culture at 3 months was negative and no reflux was demonstrated on VCUG. The student's t test was used for data analysis. RESULTS: The mean age was 3.8 +/- 0.3 years, and 76% were girls. From 155 ureters treated, 10 had Grade I reflux, 42 Grade II, 76 Grade III, 25 Grade IV, and 2 Grade V. A second injection was required in 22 ureters (14.2%). The overall success rate of the procedure (Grade 0 reflux at 3 months) was 77.4% after the first injection and 83.9% after a second injection. The success rate per grade was: 100% for Grade I, 88.1% for Grade II, 86.8% for Grade III, 64% for Grade IV, and 50% for Grade V. The mean follow-up was 446 +/- 20 days. The mean volume injected/ureter was 0.6 +/- 0.03 mL. Thirteen (13) patients had UTIs after the procedure, compared to 75 before. There was a 5-fold reduction in the incidence of UTIs/year, from a mean of 0.68 +/- 0.09 pre- to 0.12 +/- 0.04 postinjection (P = 0.001). The majority of UTIs were caused by Escherichia coli (74% pre- and 82% postinjection). CONCLUSIONS: We conclude that the Deflux procedure is effective not only in eliminating VUR on radiologic studies, but also in reducing the incidence of UTIs and antibiotic use in children with VUR.

Feasibility of using near-infrared spectroscopy to diagnose testicular torsion: an experimental study in sheep.

STUDY OBJECTIVE: To assess whether near-infrared spectroscopy can detect testicular hypoxia in a sheep model of testicular torsion within 6 hours of experimental torsion. METHODS: This was a randomized, controlled, nonblinded study. Trans-scrotal, near-infrared, spectroscopy-derived testicular tissue saturation of oxygen values were obtained from the posterior hemiscrota of 6 anesthetized sheep at baseline and every 15 minutes for 6 hours after either experimental-side, 720-degree, unilateral, medial testicular torsion and orchidopexy or control-side sham procedure with orchidopexy and then for 75 minutes after reduction of torsion and pexy. Color Doppler ultrasonography was performed every 30 minutes to confirm loss of vascular flow on the experimental side, return of flow after torsion reduction, and preserved flow on the control side. RESULTS: Near infrared spectroscopy detected a prompt, sustained reduction in testicular tissue saturation of oxygen after experimental torsion. Further, it documented a rapid return of these values to pretorsion levels after reduction of torsion. Experimental-side testicular tissue saturation of oxygen fell from a median value of 59% (interquartile range [IQR] 57% to 69%) at baseline to 14% (IQR 11% to 29%) at 2.5 hours of torsion, and postreduction values were approximately 70%. Control-side testicular tissue saturation of oxygen values increased from a median value of 67% (IQR 59% to 68%) at baseline to 77% (IQR 77% to 94%) at 2.5 hours and remained at approximately 80% for the entire protocol. The difference in median testicular tissue saturation of oxygen between experimental and control sides, using the Friedman test, was found to be significant (P=.017). CONCLUSION: This study demonstrates the feasibility, in a sheep model, of using near-infrared spectroscopy for the noninvasive diagnosis of testicular torsion and for quantification of reperfusion after torsion reduction. The applicability of these findings, from an animal model using complete torsion, to the clinical setting remains to be established.

Ductal carcinoma in situ in a 16-year-old adolescent boy with gynecomastia: a case report.

Ductal carcinoma in situ (DCIS) of the male breast is rare. Even more rare is the finding of DCIS in association with gynecomastia. After an extensive literature search, only two cases have been reported in the literature, both in adults. Here we present the case of a 16-year-old adolescent boy who presented with pubertal gynecomastia that was treated with bilateral subcutaneous mastectomies. A DCIS focus was found in the right breast specimen, and the patient underwent bilateral completion total mastectomies uneventfully. Despite its rarity, surgeons should be aware of the possibility of the breast of adolescents with gynecomastia harboring a neoplastic focus.

Geographic information system localization of community-acquired MRSA soft tissue abscesses.

BACKGROUND: Soft tissue infections with methicillin-resistant Staphylococcus aureus (MRSA) pose an ever-increasing risk to children in the community. Although historically these infections were limited to children with prolonged hospitalization, the authors have seen an increase in community-acquired infections in children without identifiable risk factors. The goal of this study is to determine the incidence of truly community-acquired MRSA soft tissue infections in our community and geographically map regions of increased risk. METHODS: After obtaining the institutional review board's approval, a retrospective chart review was conducted on 195 patients records who underwent an incision and drainage of soft tissue infections from January 1, 2000, to December 31, 2003. Thirteen patients were excluded from the study because no cultures were taken at the time of incision and drainage. RESULTS: The most common organism isolated from wound culture was S aureus , 40% (73/182), of which 45% (33/73) were MRSA. Eighty-one percent (27/33) of MRSA infections were in Springfield, 1 of 18 towns represented in the patient population. Geographic information system analysis identified a significant MRSA cluster 1.96 km in diameter within the city of Springfield. CONCLUSIONS: Geography proved to be a significant risk factor for presenting with MRSA infection. Geographic maps of antibiotic resistance can be used to guide physician antibiotic selection before culture results are available. This has significant implications for the health care provider in proper antibiotic selection within the community.

Cervical spondylodiscitis from an ingested pin: a case report.

In the pediatric literature, only 1 case of cervical spondylodiscitis from an ingested foreign body is reported and this was caused by a blunt radiolucent foreign body. The authors now describe a unique case of a 13-year-old teenaged boy who presented with neck pain 6 days after accidental ingestion of a sewing pin. Uncomplicated removal of this pin was followed in 36 days by the development of cervical spondylodiscitis that failed conservative management and required surgical debridement and arthrodesis. Physicians should be aware of the possibility of this complication in any patient that presents with neck pain after foreign body ingestion.

Early experience with needleoscopic inguinal herniorrhaphy in children.

BACKGROUND/PURPOSE: To validate its safety and efficacy, the authors evaluated their early experience with needleoscopic inguinal herniorrhaphy in children. METHODS: Twelve consecutive children, older than 6 months, with unilateral (n = 8) or bilateral (n = 4) inguinal hernias underwent a needleoscopic herniorrhaphy. A 1.7-mm needle laparoscope was introduced through the umbilicus, and a grasper placed laterally was used for traction. A curved stainless steel awl introduced percutaneously anterolateral to the internal ring was used to pass a ligature circumferentially to complete an extraperitoneal high ligation of the sac (without handling the vas deferens and spermatic vessels in males). Four of 12 patients underwent their repair combined with other procedures. Children who underwent herniorrhaphy only were allowed immediate return to unrestricted activity. Data recorded with IRB approval included operating time, postoperative discomfort, recurrence, and complications. RESULTS: For herniorrhaphy only the mean operating time was 23 minutes (unilateral, n = 5) or 46 minutes (bilateral, n = 3). All were able to return to immediate unrestricted activity. None required any analgesics other than acetaminophen. There were no recurrences or complications. CONCLUSIONS: Needleoscopic inguinal herniorrhaphy in children is safe and effective. This technique potentially offers less risk of injury to cord structures with a superior cosmetic result.

Gastroesophageal reflux disease in neurologically impaired children: the role of the gastrostomy tube.

We review our experience with gastrostomy techniques in neurologically impaired (NI) children, with or without a Nissen fundoplication. The records of 130 NI children who had a gastrostomy tube (GT) placed between January 1999 and October 2001 were reviewed. Data collected included: demographics, neurological status, operative time, time to first feed, postoperative stay, analgesic requirements, follow-up, mortality and complication rates. Open GTs were placed using the standard Stamm gastrostomy technique through a midline incision and were combined with a standard open Nissen fundoplication when indicated. Laparoscopic GTs were placed after institution of carbon dioxide pneumoperitoneum using a 2-port technique, a Mic-key G device of appropriate size and anchored to the anterior abdominal wall with 2 "U" stitches. The laparoscopic Nissen fundoplication (LNF) procedures were performed using a 5-port technique. Patients were divided into 4 groups: group I (n = 12) laparoscopic GT alone, group II (n = 44) open GT alone, Group III (n = 44) laparoscopic GT with LNF and Group IV (n = 30) open GT with Nissen fundoplication. Based on their similar characteristics, Groups I and II and Groups III and IV were compared together. Data were analysed using Student's t test, and internal review board approval was obtained. Patients ranged in age between 10 days and 17.7 years (mean 3.64 years). Their weight was between 1.2 and 63.4 kg (mean 12.8 kg). The compared groups showed similar characteristics with regard to age, weight, cause of mental impairment, and the reason for placement of the GT. The operative time for group III was significantly longer than that of group IV (P < 0.05). Time to first feed was significantly shorter for group I when compared to group II. The postoperative analgesic requirements were not statistically different. The overall short- and long-term complication rates were not statistically different when the related groups were compared, however, site-related complications and feeding problems were significantly less in group I compared to group II. Only 1 operative mortality occurred in group III. Follow-up showed less long-term morbidity and fewer complications with the laparoscopic GT compared to the open one as regard to admissions, surgery, and emergency department visits related to GT problems as well as frequency of GT change. Based on our experience, laparoscopic placement of a low-profile GT in NI children appears to be associated with less morbidity, permits earlier enteral nutrition, and has a cosmetic advantage. We believe that the laparoscopic technique should be the procedure of choice for GT placement in these children even when a Nissen fundoplication is deemed necessary.
