Urinary Tract Infection Caused By Bacterial Pathogens of The Respiratory Tract In Children

Urinary tract infection (UTI) caused by bacterial pathogens of the respiratory tract such as Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis is rare and little is known about their characteristics and potential host risk factors. We conducted a retrospective descriptive study on pediatric UTI due to S. pneumoniae, Haemophilus spp., or M. catarrhalis at a tertiary-care pediatric hospital. Pediatric patients with diagnosed UTI between 2002 and 2020 were included. Patient demographics, laboratory data, and microbiological findings were extracted from their electronic medical records and the infectious disease surveillance system. Among 46,332 urine samples, 76 bacteriuria (0.16%) and 22 UTI (0.05%) events due to the targeted species were identified (S. pneumoniae [n=7] and Haemophilus spp. [n=15]). Of the patients, 17 (85%) had underlying urinary tract abnormalities and 13 (60%) had vesicocutaneous fistula. All the UTI episodes caused by S. pneumoniae and Haemophilus spp. occurred after cystostomy. All the patients had satisfactory clinical outcomes.Conclusion: Although S. pneumoniae and Haemophilus spp. are rare causes of UTI in children, they could be the true causative bacteria of UTI even when detected in urine specimens, particularly in the patients with urinary tract abnormalities and vesicocutaneous fistula.

Embarazo a término en útero bicorne con cuerno rudimentario no comunicante. Reporte de un caso

The bicorne uterus with a rudimentary non-communicating horn may be associated with gynecological and obstetric complications such as infertility, endometriosis, hematometra, urinary tract abnormalities, abortions, and preterm deliveries. Excision of the rudimentary horn should be done outside of pregnancy, with followup during pregnancy, looking for complications. We present the case of a 40-year-old patient, who presented abdominal pain and vaginal bleeding, with a full-term pregnancy in a rudimentary non-communicating horn of a bicorne uterus. Physical examination showed abdominal distention and loss of uterine contour and no fetal parts were palpated. The provisional diagnosis of rupture of the uterus was made. Emergency laparotomy revealed a dead and deformed fetus, 37 weeks old, in a bicorne uterus with a broken rudimentary non-communicating horn, along with an acretic placenta. Extraction of the gestational sac, fetus and placenta and subtotal hysterectomy with conservation of the left annex were performed.

Case Report: Novel Copy Number Variant 16p11.2 Duplication Associated With Prune Belly Syndrome

Prune belly syndrome (PBS) is a rare congenital disease that predominantly occurs in males and is identified by its classic triad of abdominal wall musculature deficiencies, cryptorchidism, and urinary tract abnormalities. However, numerous anomalies involving the kidneys, heart, lungs, and muscles have also been reported. A multitude of chromosomal abnormalities have been implicated in its pathogenesis. PBS can occur in association with trisomy 18 and 21. Gene duplications and deletions have also been reported; however, a definite cause of PBS is still unknown. We report the first PBS patient with a copy number variant in 16p11.2.

ECTOPIC KIDNEY DISCOVERED AFTER ABDOMINAL TRAUMA: ABOUT ONE CASE REPORT

Pelvic kidney ectopia is one of most frequent upper urinary tract abnormalities exposed to trauma injuries.In that matter a patient presented with hematuria and abdominal pain in a trauma setting should make us consider this diagnosis.The abdominal CT scan is the key to make the diagnosis and allows to assess the type and severity of the lesions.

CT features of feline lipiduria and renal cortical lipid deposition

Objectives The aims of this study were to document the presence and prevalence of feline lipiduria and renal lipid deposition on CT, and to search for associations between the presence of lipiduria and sex, urinary tract abnormalities and urolithiasis. Methods The CT examinations of 252 cats were reviewed for the presence of an antigravitational hypodense bubble in the urinary bladder with density values between −180 Hounsfield units (HU) and −20 HU. To identify associations between lipiduria and sex, urinary tract abnormalities and urolithiasis, Fisher’s exact test was used. Renal cortical density measurement was performed in all cats. The Mann−Whitney test was performed to compare renal cortical density between lipiduric and unaffected cats. Results A total of 27 domestic cats (10.7%) had CT evidence of lipiduria. Lipiduric cats had a significantly lower renal cortical density than unaffected cats ( P <0.01). Male neutered cats had a significantly higher frequency of lipiduria and lower renal cortical density compared with female neutered cats ( P <0.01). There was no significant difference between the groups regarding renal, ureteral or urethral abnormalities. Conclusions and relevance Lipiduria is a common physiological phenomenon in cats that can be detected on routine CT examinations. Decreased renal cortical density is associated with lipiduria. This may aid in the diagnosis of feline lipiduria and help to differentiate its presence from other pathological depositions and excretions.

Malformaciones urológicas en niños, en el Servicio de Cirugía Pediátrica del Hospital José Carrasco Arteaga. Enero 2014 – Diciembre 2018

BACKGROUND: Congenital urinary tract abnormalities are diverse, and can affect different structures of this system. The importance of early diagnosis is avoiding kidney damage in the children. The aim of this study was to identify the frequency of urinary tract abnormalities in pediatric patients, in Hospital José Carrasco Arteaga Pediatric Surgery Department, from January 2014 to December 2018. METHODS: Descriptive cross-sectional study. The universe were 230 pediatric patients with confirmed diagnosis of congenital urinary tract abnormalities, from Hospital José Carrasco Arteaga Pediatric Surgery Department, from January 2014 to December 2018. Incomplete medical charts were excluded (n=47 children). 183 children were part of the this study. . La malformación más frecuente fue la hidronefrosis transitoria 70%, seguida de reflujo Vesico-Ureteral (RVU) 16.39% (n=30), estenosis pieloureteral 5.46% (n=10), megauréter 6.55% (n=12) y displasia renal 1.63% (n=3). RESULTS: The frequency of urological abnormalities was 2.73% (n = 183), predominately infants with 56%, and 57% male. 26.78% presented with symptoms related to urinary tract infection. Ultrasound was performed in 95% of the children, urethrocistography in 55% and renal scintigraphy in 31%. Prenatal findings were found in 34.97%. The most frequent abnormality was transient hydronephrosis (70%), followed up by vesico-ureteral reflux (VUR) 16.39% (n = 30), pyeloureteral stenosis 5.46% (n = 10), megaureter 6.55% (n = 12) and renal dysplasia 1.63% (n = 3). CONCLUSION: Urological malformations are common between genetic abnormalities, most of them are asymptomatic; locally due to the low rate of prenatal diagnosis, they are diagnosed in between 24 months of age. Transient hydronephrosis is the most frequent abnormality. Urinary tract infections are commonly the starting line in this groups of patients; when malformations are suspected, ultrasound is always suitable.
