Abstract
Nematodes in the genus Phasmarhabditis can infect and kill slugs and snails, which are important agricultural pests. This useful trait has been commercialized by the corporation BASF after they mass produced a product labeled Nemaslug®. The product contains Phasmarhabditis hermaphrodita, which has been cultured with Moraxella osloensis, a bacterial strain that was originally thought to be responsible for causing mortality in slugs and snails. The exact mechanism leading to death in a Phasmarhabditis infected host is unknown but may involve contributions from nematode-associated bacteria. The naturally occurring microbial community of Phasmarhabditis is unexplored; the previous Phasmarhabditis microbial community studies have focused on laboratory grown or commercially reared nematodes, and in order to obtain a deeper understanding of the parasite and its host interactions, it is crucial to characterize the natural microbial communities associated with this organism in the wild. We sampled Phasmarhabditis californica, Phasmarhabditis hermaphrodita, and Phasmarhabditis papillosa directly from their habitats in Central and Southern California nurseries and garden centers and identified their native microbial community via 16S amplicon sequencing. We found that the Phasmarhabditis microbial community was influenced by species, location, and possibly gastropod host from which the nematode was collected. The predominant bacteria of the Phasmarhabditis isolates collected included Shewanella, Clostridium perfringens, Aeromonadaceae, Pseudomonadaceae, and Acinetobacter. Phasmarhabditis papillosa isolates exhibited an enrichment with species belonging to Acinetobacter or Pseudomonadaceae. However, further research must be performed to determine if this is due to the location of isolate collection or a species specific microbial community pattern. More work on the natural microbial community of Phasmarhabditis is needed to determine the role of bacteria in nematode virulence.

Abstract
Cholera is a severe diarrheal disease that places a significant burden on global health. Cholera's high morbidity demands effective prophylactic strategies, but oral cholera vaccines exhibit variable efficacy in human populations. One contributor of variance in human populations is the gut microbiome, which in cholera-endemic areas is modulated by malnutrition, cholera, and non-cholera diarrhea. We conducted fecal transplants from healthy human donors and model communities of either human gut microbes that resemble healthy individuals or those of individuals recovering from diarrhea in various mouse models. We show microbiome-specific effects on host antibody responses against Vibrio cholerae, and that dysbiotic human gut microbiomes representative of cholera-endemic areas suppress the immune response against V. cholerae via CD4+ lymphocytes. Our findings suggest that gut microbiome composition at time of infection or vaccination may be pivotal for providing robust mucosal immunity, and suggest a target for improved prophylactic and therapeutic strategies for cholera.

Abstract
Abstract
Vibrio cholerae is the etiologic agent of cholera, a severe diarrheal disease that represents a significant burden on global health and productivity. Given the need for more effective prophylactics, more research is needed to ascertain the interplay of protective immune responses and the resident gut microbiome, which in cholera-endemic areas is strongly and repeatedly modulated by malnutrition, cholera, and non-cholera infectious diarrhea. Initially, we conducted fecal transplants from healthy human donors into germ-free mice in order to characterize differential immune response activity. As we observed distinctive responses in our initial sampling, we moved to a more tractable antibiotic-treated mouse model where we assemble representative model communities of either human gut microbes resembling those of healthy individuals or those of individuals recovering from diarrhea or malnutrition. We establish these communities in a murine infection model, and show that the dysbiotic gut microbiome, commonly present in areas where malnutrition and diarrhea are common, suppresses the immune response against Vibrio cholerae through the action of CD4+ cells. Our findings suggest that the composition of the gut microbiome at time of infection may be pivotal for providing robust mucosal immunity, suggesting a target for the improvement of responses to oral cholera vaccines.

Abstract
The gut microbiome is the resident microbial community of the gastrointestinal tract. This community is highly diverse, but how microbial diversity confers resistance or susceptibility to intestinal pathogens is poorly understood. Using transplantation of human microbiomes into several animal models of infection, we show that key microbiome species shape the chemical environment of the gut through the activity of the enzyme bile salt hydrolase. The activity of this enzyme reduced colonization by the major human diarrheal pathogen Vibrio cholerae by degrading the bile salt taurocholate that activates the expression of virulence genes. The absence of these functions and species permits increased infection loads on a personal microbiome-specific basis. These findings suggest new targets for individualized preventative strategies of V. cholerae infection through modulating the structure and function of the gut microbiome.

Abstract
Backround The primary aim of this study was to investigate information needs and treatment preferences of patients with ovarian cancer, focusing especially on physician-patient relationship and treatment. Patients and methods A questionnaire was developed based on the experiences of the national German survey 'Expression II', and was provided to patients with ovarian cancer either at initial diagnosis or with recurrent disease via Internet (online-version) or as print-out-version. Results From December 2009 to October 2012, a total of 1830 patients with ovarian cancer from eight European countries (Austria, Belgium, France, Germany, Italy, Poland, Romania, Spain) participated, 902 (49.3%) after initial diagnosis and 731 (39.9%) with recurrent ovarian cancer. The median age was 58 years (range 17-89). Nearly all patients (96.2%) had experienced upfront surgery followed by first-line chemotherapy (91.8%). The majority of patients were satisfied with the completeness and comprehensibility of the explanation about the diagnosis and treatment options. The three most important aspects, identified by patients to improve the treatment for ovarian cancer included: 'the therapy should not induce alopecia' (42%), 'there must be more done to counter fatigue' (34.5%) and 'the therapy should be more effective' (29.7%). Out of 659 (36%) patients, who were offered participation in a clinical trial, 476 (26%) were included. Conclusion This study underlines the high need of patients with ovarian cancer for all details concerning treatment options irrespective of their cultural background, the stage of disease and the patient's age. Increased information requirements regarding potential side effects and treatment alternatives were recorded. Besides the need for more effective therapy, alopecia and fatigue are the most important side effects of concern to patients.

Abstract
BACKGROUND Aim of this study was to analyze the impact of pain on quality of life and survival in recurrent OC patients. METHODS Raw data including the QLQ-C30 questionnaire from three phase II/III trials ("Topotecan phase III," "Hector," and "TRIAS") conducted by the North-Eastern German Society of Gynecological Oncology (NOGGO) were synthesized and analyzed using logistic and Cox regression analyses. RESULTS Data on pain was available for 952 patients out of 1226. Moderate to severe pain, which was defined as pain ≥ 50 in the QLQ-C30 symptom scale, was experienced by more than one-third of patients (36.6%). A total of 31% were taking non-opioid pain medication and 16% opioids. Median age at randomization was 61 years (range 25-84). Most patients (84.7%) were diagnosed in FIGO III/IV. Pain was independent from age, FIGO stage, grading, amount of recurrences, and chemotherapy-free interval. ECOG was significantly worse in patients with pain (p < 0.001). Fatigue, nausea/vomiting, sleeping disorders, and abdominal symptoms such as loss of appetite, diarrhea, and constipation were more frequently found in patients with pain (all p < 0.001). Quality of life was significantly diminished (p < 0.001). Pain was also an independent marker for overall survival (OS). Median OS was 18.2 months in patients with pain compared with 22.0 months in patients without pain (p = 0.013, HR 1.25, 95% confidence interval 1.05-1.48). OS was shorter in patients with pain and without pain medication compared with those on sufficient pain medication, whereas OS was mostly decreased in patients having pain despite pain medication (18.5, 19.6, and 15.0 months respectively; p = 0.026). Progression-free survival and prior treatment discontinuation were not associated with pain. CONCLUSION Best supportive care including sufficient pain medication should be delivered as early as possible because effective pain management is crucial for both quality of life and overall survival in patients with recurrent ovarian cancer.

Abstract
The quantification of total starch content (TS) or degree of starch gelatinization (DG) in animal feed is always challenging because of the potential interference from other ingredients. In this study, the differences in TS or DG measurement in pelleted swine feed due to variations in analytical methodology were quantified. Pelleted swine feed was used to create 6 different diets manufactured with various processing conditions in a 2 × 3 factorial design (2 conditioning temperatures, 77 or 88°C, and 3 conditioning retention times, 15, 30, or 60 s). Samples at each processing stage (cold mash, hot mash, hot pelletized feed, and final cooled pelletized feed) were collected for each of the 6 treatments and analyzed for TS and DG. Two different methodologies were evaluated for TS determination (the AOAC International method 996.11 vs. the modified glucoamylase method) and DG determination (the modified glucoamylase method vs. differential scanning calorimetry [DSC]). For TS determination, the AOAC International method 996.11 measured lower TS values in cold pellets compared with the modified glucoamylase method. The AOAC International method resulted in lower TS in cold mash than cooled pelletized feed, whereas the modified glucoamylase method showed no significant differences in TS content before or after pelleting. For DG, the modified glucoamylase method demonstrated increased DG with each processing step. Furthermore, increasing the conditioning temperature and time resulted in a greater DG when evaluated by the modified glucoamylase method. However, results demonstrated that DSC is not suitable as a quantitative tool for determining DG in multicomponent animal feeds due to interferences from nonstarch transformations, such as protein denaturation.

Abstract
OBJECTIVE Overdrainage in children is a long-term problem for shunted patients which might lead to chronic anatomical changes. In order to prevent these problems, valve exchange is performed on a regular basis in patients without hydrostatic units towards a valve with both an adjustable and a gravitational unit. The clinical outcome of these patients is reported in a retrospective study. METHODS Between 2009 and 2014, the in-house database was analyzed for patients who received a valve exchange towards an adjustable differential pressure valve with gravitational unit. The study protocol included the patients shunt history, image analysis for ventricular width, and necessity of revision surgery after valve exchange. A questionnaire was sent to the patients in order to ask for their subjective experience for symptom changes and treatment experience. RESULTS Forty-six patients were identified (26 girls, mean age 11.8 ± 6.1 years) with a mean follow-up of 36.3 ± 15 months. The ventricular width did increase after valve exchange as measured in frontal and occipital horn ratio (0.364 ± 0.032 vs. 0.402 ± 0.09, p = 0.0017). Of the patients suffering from acute symptoms, 89% improved after treatment. The shunt and valve survival rates were 88 and 95%, respectively, after 12 months. Comparing the total amount of revisions before and after valve exchange, a significant reduction was seen in total but a no significant difference was analyzed in amount of revisions to time ratio. CONCLUSION Valve exchange might be cautiously decided if patients seem to perform clinically well. In our study, we were able to show that the strategy of valve exchange to prevent chronic overdrainage is well tolerated and seem to improve patient's clinical outcome in terms of ventricular width, symptom relieve, and revision rate.

Abstract
Prostate cancer (PCa) is the most commonly diagnosed non-cutaneous cancer in men in the western world. Mutations in tumor suppressor genes and in oncogenes are important for PCa progression, whereas the role of stem cell proteins in prostate carcinogenesis is insufficiently examined. This study investigates the role of the transcriptional regulator Ecotropic Viral Integration site 1 (EVI1), known as an essential modulator of hematopoietic and leukemic stem cell biology, in prostate carcinogenesis. We show that in healthy prostatic tissue, EVI1 expression is confined to the prostate stem cell compartment located at the basal layer, as identified by the stem cell marker CD44. Instead, in a PCa progression cohort comprising 219 samples from patients with primary PCa, lymph node and distant metastases, EVI1 protein was heterogeneously distributed within samples and high expression is associated with tumor progression (P<0.001), suggesting EVI1 induction as a driver event. Functionally, short hairpin RNA-mediated knockdown of EVI1 inhibited proliferation, cell cycle progression, migratory capacity and anchorage-independent growth of human PCa cells, while enhancing their apoptosis sensitivity. Interestingly, modulation of EVI1 expression also strongly regulated stem cell properties (including expression of the stem cell marker SOX2) and in vivo tumor initiation capacity. Further emphasizing a functional correlation between EVI1 induction and tumor progression, upregulation of EVI1 expression was noted in experimentally derived docetaxel-resistant PCa cells. Importantly, knockdown of EVI1 in these cells restored sensitivity to docetaxel, in part by downregulating anti-apoptotic BCL2. Together, these data indicate EVI1 as a novel molecular regulator of PCa progression and therapy resistance that may control prostate carcinogenesis at the stem cell level.

Abstract
Adrenocortical tumour is rare in children. We report on a female infant with adrenocortical carcinoma presenting with pseudoprecocious puberty at the age of two. She had a history of gradually increasing public hair growth after birth. Physical examination showed signs of virilisation such as pubic hair growth and hirsutism with evidence of facial hair growth. On biochemical evaluation, DHEA-S, 17-OH progesterone, and testosterone levels were elevated. An abdominopelvic spiral computed tomography (CT) scan with intravenous contrast identified a well-defined heterogeneously enhanced mass with areas of necrosis in the right adrenal gland and downward displacement of the underlying kidney. There was no evidence of distant metastasis on CT imaging. An exploratory laparotomy was performed in which a large, haemorrhagic and necrotic mass in the right adrenal gland with pressure effect on right liver lobe and signs of thrombosis in the inferior vena cava was detected. Pathologic examination confirmed the adrenocortical carcinoma. She received eight cycles of adjuvant chemotherapy with Carboplatin, Etoposide, and Doxorubicin regimens and underwent follow-up visits thereafter in which no sign of recurrence was observed. In conclusion, adrenocortical carcinomas are rare in children, but they should be considered in any child presenting with signs of pseudoprecocious puberty.

Abstract
The nonbiodegradable and nonrenewable nature of plastic packaging has led to a renewed interest in packaging materials based on bio-nanocomposites (biopolymer matrix reinforced with nanoparticles such as layered silicates). One of the reasons for unique properties of bio-nanocomposites is the difference in physics at nanoscale as compared to that at macroscale. Therefore, the effect of nanoscale on the properties of bio-nanocomposites is discussed. Properties of bio-nanocomposites are governed by the extent of dispersion of nanoparticles in the biopolymer matrix and interaction between nanoparticles and the biopolymer. Selection of proper technique to determine properties of these bio-nanocomposites is very critical in assessing their performance. Experimental techniques (tensile testing, barrier property measurement, dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis, rheological measurement) to determine the mechanical, barrier, thermal, and rheological properties of bio-nanocomposites are discussed in terms of methodology, interpretation of results, and application in studying the properties of bio-nanocomposites. Mathematical modeling plays an important role in predicting the properties of bio-nanocomposites and comparing them to the measured properties. This comparison helps in better understanding the mechanism for much improved properties of bio-nanocomposites. Mathematical modeling is also helpful in understanding the effects of different parameters on the properties of bio-nanocomposites. Therefore, the article describes mathematical modeling of mechanical and barrier properties of bio-nanocomposites using analytical micromechanics.

Abstract
The nonbiodegradable and nonrenewable nature of plastic packaging has led to a renewed interest in packaging materials based on bio-nanocomposites (biopolymer matrix reinforced with nanoparticles such as layered silicates). Bio-nanocomposite films based on soy protein isolate (SPI) and modified montmorillonite (MMT) were prepared using melt extrusion. The effect of different type (Cloisite 20A and Cloisite 30B) and content (0% to 15%) of modified MMT on the structure (degree of intercalation and exfoliation) and properties (color, mechanical, dynamic mechanical, thermal stability, and water vapor permeability) of SPI-MMT bio-nanocomposite films were investigated. Extrusion of SPI and modified MMTs resulted in bio-nanocomposites with exfoliated structures at lower MMT content (5%). At higher MMT content (15%), the structure of bio-nanocomposites ranged from intercalated for Cloisite 20A to disordered intercalated for Cloisite 30B. At an MMT content of 5%, bio-nanocomposite films based on modified MMTs (Cloisite 20A and Cloisite 30B) had better mechanical (tensile strength and percent elongation at break), dynamic mechanical (glass transition temperature and storage modulus), and water barrier properties as compared to those based on natural MMT (Cloisite Na(+)). Bio-nanocomposite films based on 10% Cloisite 30B had mechanical properties comparable to those of some of the plastics that are currently used in food packaging applications. However, much higher WVP values of these films as compared to those of existing plastics might limit the application of these films to packaging of high moisture foods such as fresh fruits and vegetables.

Abstract
Griscelli syndrome type 2 is a rare autosomal recessive primary immunodeficiency disease caused by a mutation in the RAB27A gene and characterized by oculocutaneous hypopigmentation and variable cellular immunodeficiency. We report the case of a 6-month-old infant with silvery hair, eyelashes, and eyebrows who was referred to our center because of fever and hepatosplenomegaly. Bone marrow studies indicated hemophagocytosis, whilst microscopic examination of the hair showed irregular agglomerations of pigment in hair shafts. Molecular analysis revealed a novel homozygous mutation in exon 5, namely, a single-base substitution (g.42996 A>G) leading to an amino acid change (S115G) and thus confirming the diagnosis of Griscelli syndrome type 2. Griscelli syndrome could be more common than thought, especially in regions with high rates of consanguinity. As the prognosis of disease is usually poor, prompt diagnosis and appropriate treatment are vital to avoid complications.

Abstract
OBJECTIVES To compare the ability of total prostate (TP) and transition zone (TZ) volume to predict the outcome of a repeat prostate biopsy in patients with serum prostate-specific antigen (PSA) levels of 4 to 10 ng/mL. METHODS A total of 1137 patients were included and underwent transrectal ultrasound-guided needle sextant and two transition zone biopsies of the prostate. All patients with a prior negative biopsy (benign prostatic tissue) underwent a repeat biopsy after 6 weeks. The TP and TZ volumes of the prostate were measured by transrectal ultrasonography. RESULTS Of the 1137 patients, prostate cancer was diagnosed in 364 (32%), in 276 (24.2%) after the first biopsy and in 88 (7.7%) after the repeated biopsy. The TP and TZ volumes were larger in the patients with prostate cancer detected on the repeated biopsy (P <0.0001). Using a cutoff for TP volume of less than 20 cm3 and greater than 80 cm3 and for TZ volume of less than 9 cm3 and greater than 41 cm3 would have spared 7.1% and 10% of repeated biopsies, respectively. CONCLUSIONS The probability for a positive repeat prostate biopsy increases in a logarithmic function for larger prostates, as well as for larger TP and, especially, for larger TZ volumes. The probability of finding prostate cancer on a repeat biopsy in prostates with small (less than 20 cm3) and large (greater than 79 cm3) TP, as well as in small (less than 9.3 cm3) and large (greater than 41 cm3) TZ volumes, was very low. Therefore, a repeat prostate biopsy within 6 weeks is unnecessary. These patients should be followed up by serial PSA determination.

Abstract
The dynamics of tip-induced, resonance-mediated bond-breaking in complex organic adsorbates is studied theoretically and experimentally. Desorption of benzene from a Si(100) surface is found to be efficient and sensitive to voltage, the measured yield rising from below 10(-10) to ca. 10(-6) per electron within a ca. 0.8 V range at low (< 100 pA) current. A theoretical model, based upon first principles electronic structure calculations and quantum mechanical wavepacket simulations, traces these observations to multi-mode dynamics triggered by a transition into a cationic resonance. The model is generalized to provide understanding of, and suggest a means of control over, the behaviour of different classes of organic adsorbates under tunneling current.

Abstract
A retrospective review of 14 patients with adenoid cystic carcinoma of the tongue treated between 1955 and 1997 was performed. Treatment consisted of surgery (n = 2), radiotherapy (n = 2), chemotherapy (n = 1), or combination therapy (n = 9). The 2-, 5-, and 10-year absolute survival rates were 92%, 79%, and 63%, respectively. Seventy-five percent of the patients who died of cancer succumbed to distant metastases. However, long-term survival was common despite a high incidence of local and distant recurrence. The presence of positive surgical margins, the incidence of regional metastases, the incidence of perineural invasion, the initial stage of disease, and the eventual development of locoregional recurrence and distant metastases did not significantly alter the survival rate. Surgical extirpation combined with postoperative radiotherapy is advocated for the treatment of adenoid cystic carcinoma of the tongue. Given the indolent nature of this disease process, surgery should be directed toward conservation of speech and swallowing function.

Abstract
BACKGROUND Parathyroid adenoma is the most common cause of primary hyperparathyroidism (pHPT). Adenomas usually involve only a single gland, and the remaining glands are normal or suppressed. Multiple parathyroid adenomas have been reported to occur in as high as 11% of patients with pHPT. The significant incidence of multiple adenomas with histologic similarities to hyperplasia has raised the possibility that adenoma is a continuation of the hyperplasia state. To test this theory, we used molecular genetics to compare clonality and proliferative activity of parathyroid adenoma with its corresponding normal glandular tissue. Furthermore, we devised a scheme to definitively distinguish between the different parathyroid states on a molecular level, because histologic distinction is unreliable. METHODS The study included three patients with a diagnosis of singular parathyroid adenoma and three with double parathyroid adenomas. Paraffin-embedded surgical specimens of both adenomas and normal glands were retrieved from each patient. Clonal analysis of the phosphoglycerolkinase (PGK) gene has suggested that parathyroid adenomas are monoclonal. Clonality of parathyroid adenomas and normal parathyroid glands was studied by polymerase chain reaction-based restriction fragment length polymorphic analysis for the PGK gene. Proliferative activity of the specimens was also analyzed using the immunohistochemical markers PCNA and Ki-67. RESULTS All adenomas were monoclonal and all normal parathyroid glands were polyclonal for the PGK gene in both the single and double adenoma specimens. All adenomas stained positive for proliferative activity. In the three patients with singular adenoma, proliferative activity was not detected in the normal parathyroid tissue. However, in the double adenoma group, two of the three patients showed hyperproliferative activity in the normal glands. CONCLUSION Proliferative activity consistent with hyperplasia was present in some normal glands of multiple adenoma patients. Our observation supports the theory that multiple adenomas may be a continuation of the hyperplasia state.

Abstract
PURPOSE During the past 30 years, radiation therapy with 28 to 30 Gy for para-aortic and ipsilateral iliac node areas was the standard adjuvant treatment for clinical stage I seminoma after orchiectomy. However, late effects of radiotherapy prompted a search for alternative adjuvant treatment approaches, including surveillance and application of carboplatin. In this retrospective analysis, we evaluated the efficacy and toxicity of two adjuvant single-agent carboplatin courses in 107 patients who were diagnosed with clinical stage I seminoma at our study centers between 1988 and 1999. PATIENTS AND METHODS All 107 patients (median age, 39 years; range, 24 to 63 years) received two postoperative adjuvant cycles of carboplatin (400 mg/m(2)). The pathologic tumor stage was pT1 in 84 patients, pT2 in 18 patients, and pT3 in five patients. Whole blood count and serum chemistry were evaluated weekly during treatment to assess hematologic and nonhematologic toxicity. RESULTS Six patients died from tumor-unrelated causes. The remaining 101 patients are currently alive and free of disease after a median follow-up of 74 months (range, 5 to 145 months). A detailed analysis of hematologic toxicity showed only World Health Organization (WHO) grade 1 leukocytopenia in 10.7% of all cycles and WHO grade 2 leukocytopenia in 2.1% of all cycles. CONCLUSION Regarding the absence of tumor recurrences in our retrospective analysis and the favorable toxicity profile with no episodes of long-term toxicity, we suggest that two adjuvant courses of single-agent carboplatin for clinical stage I seminoma patients might be equivalent to radiotherapy.

Abstract
A scanning-tunneling microscope has been used to induce efficient local desorption of benzene from Si(100) at low currents (<100 pA), sample biases (approximately -2.4 V) and temperatures (22 K). A theoretical model based upon first principles electronic structure calculations and quantum mechanical wave packet dynamics describes this process as occurring via transient ionization of a pi state of the adsorbed molecule. This model accounts for the unexpected efficiency and sharp threshold of the yield.

Abstract
PURPOSE To evaluate the efficacy of high-energy transurethral microwave thermotherapy (TUMT) in the treatment of chronic urinary retention (CUR) due to benign prostatic hyperplasia (BPH). MATERIALS AND METHODS In this prospective cohort study, 29 patients with CUR due to BPH underwent high-energy TUMT. Prior to treatment and during a 12-week follow-up, the following parameters were determined: quality of life (QOL) score, peak flow rate (Qmax) by uroflowmetry, and postvoid residual urine (PVR). In those with treatment failure (PVR > 150 mL or urinary retention), pressure-flow studies were performed and compared to pre-TUMT urodynamics. RESULTS Of the 29 patients, 21 (72%) regained the ability to void spontaneously at 5 weeks. The actuarial median time for spontaneous voiding to be restored was 3.5 weeks (95% confidence interval [CI] 2.9-4.8 weeks). Mean QOL score at 12 weeks post-TUMT (2.2; 95% CI 1.5-2.7) was lower than that at 1 week (4.6; 95% CI 3.9-5.8) by 51% (p < 0.0005). Further, a 55% increase in mean Qmax (p < .0005) determined by uroflowmetry was observed by 12 weeks vs. 1 week after high-energy TUMT. TUMT failed in 8 patients due to a hypocontractile detrusor. CONCLUSIONS We concluded that high-energy TUMT is a potentially useful option for patient with CUR who are not candidates for prostatectomy.

Abstract
Branchial cleft anomalies are congenital developmental defects that typically present as a soft fluctuant mass or fistulous tract along the anterior border of the sternocleidomastoid muscle. However, branchial anomalies can manifest atypically, presenting diagnostic and therapeutic challenges. Error or delay in diagnosis can lead to complications, recurrences, and even life-threatening emergencies. We describe a case of an infected branchial cleft cyst that progressed to a retropharyngeal abscess in a 5-week-old female patient. The clinical, radiographic, and histologic findings of this rare presentation of branchial cleft cyst are discussed.
