Presence of tubuloreticular inclusions in ultrastructural studies of renal biopsies in children with lupus nephropathy - one-center preliminary study

Introduction

Juvenile systemic lupus erythematosus (jSLE) is an autoimmune disease that develops as a result of multi-level immune dysregulation, including the interferon pathway. Nephropathy develops at an early stage and eventually affects 90% of patients. A renal biopsy allows one to classify lupus nephritis and determine the proper treatment. Biopsy assessment should be done not only in a light microscope but also in a transmission electron microscope (TEM). Its usage may reveal the presence of intracellular tubuloreticular inclusions (TRIs), considered as a morphological marker of interferon hyperactivity.

Material and methods

Renal biopsies of 10 children with jSLE and nephropathy were analyzed in TEM. The location, structure, and size of TRIs were assessed. Demographic data, nephropathy manifestation, non-renal symptoms, and serological activity of lupus were analyzed.

Results

All the patients were female with an average onset at 12.7 years of age and met SLE criteria. Nephropathy manifested with proteinuria (n = 10) and hematuria (n = 6). Glomerular filtration rate (GFR) was normal in all patients. In three children with early disease onset, it manifested with hematological disorders. TRIs were revealed in 7 biopsies, with the highest expression in the youngest children, with peripheral cytopenia, membranous glomerulonephritis, and lupus nephritis.

Conclusions

Demonstration of TRIs in renal biopsies of children with juvenile systemic lupus may confirm the diagnosis of lupus nephritis and is a sign of involvement of the interferon pathway at the early stage of the disease.

Uterine corpus rhabdomyosarcoma in 13-year-old girl

Embryonal rhabdomyosarcoma (RMS) is the most common malignant tumor of the genitourinary system in children. The most common symptoms in girls include vaginal bleeding, abdominal pain, urinary and/or stool incontinence and hematuria. Treatment includes primary resection of the tumor and adjuvant therapy or neoadjuvant chemotherapy, resection of the tumor and adjuvant therapy.

Pulmonary function, exercise capacity and dyspnea in patients 7 ​years after Nuss surgery

PURPOSE

Pectus excavatum is a frequent thoracic malformation increasingly treated with minimally invasive methods (MIRPE), which are performed for cardio-respiratory problems and in some centers also for esthetic considerations. Theoretically, MIRPE may increase thoracic elastic recoil, work of breathing and cause emphysema. The aim of the present study was to determine whether teenagers who underwent MIRPE may expect normal thoracic cage development, cardio-respiratory function, exercise capacity and asymptomatic functioning.

MATERIAL AND METHODS

Fifty five patients (21.1 ​± ​3.0 years) who underwent MIRPE between 2000 and 2010 were assessed 6.8 (±2.4) years after surgery. Controls were matched for sex, age and height to the intervention participants. Spirometry, body plethysmography, diffusion capacity and the 6 ​min walking test (6MWT) were performed. Anteroposterior (AP) and transverse chest diameters were measured.

RESULTS

Participants who underwent MIRPE had normal pulmonary function, and exercise capacity. After adjustment for potential confounders, the intervention group had lower mean BMI [-1.88 ​± ​0.56 (kg/m²); p ​= ​0.001] and chest AP diameter [-2.79 ​± ​0.57 (cm); p ​< ​0.001], but higher residual volume (RV%) [12.98 ​± ​5.31 (%); p ​= ​0.001], RV% total lung capacity (TLC) [5.56 ​± ​0.92 (%); p ​< ​0.001], forced expiratory volume in 1 ​s/forced vital capacity (FEV₁/FVC) [2.64 ​± ​1.28 (%); p ​= ​0.039] and 6MWT distance [29.10 ​± ​13.02 (m); p ​= ​0.025].

CONCLUSIONS

Young adults who undergo MIRPE may expect normal pulmonary function and exercise capacity. Observed differences in air trapping require further assessment in terms of emphysema development risk.

Multiple variants of obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome - one clinical center case series and the systematic review of 734 cases

INTRODUCTION

Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare female urogenital tract malformation.

STUDY OBJECTIVE

To present 10 patients with OHVIRA treated at the clinical center. To perform a systematic review of OHVIRA case series related to the prevalence of anatomical variants, surgical interventions and endometriosis, and to compare them with our case series.

MATERIALS AND METHODS

Medical records from 10 OHVIRA patients treated between 2016 and 2020 were retrospectively reviewed. For the systematic review, PubMed and Web of Science were used to search for relevant studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were strictly followed.

RESULTS

The most common anatomical variant includes left obstructed hemivagina (50.7%) with isolated hematocolpos or hydrocolpos (55.9%), uterus didelphys (82.9%), and ipsilateral renal agenesis (92.2%). Vaginal septectomy was the most common surgical approach (86.5%). Hemivaginectomy (2.2%), hemihysterectomy (4.2%), or total hysterectomy (0.7%) were also performed in several patients. Some subjects required salpingectomy (3.3%) or oophorectomy (1.8%). 7.5% of patients, mainly infants, did not require surgery due to the spontaneous resolution of hydrocolpos. Endometriosis was fortuitously found in 13.6% of the selected cases who underwent laparoscopy or laparotomy.

DISCUSSION

The most common variant of OHVIRA includes isolated hematocolpos and a thick vaginal septum between adjacent hemivaginas. Endometriosis was present in approximately 14% of OHVIRA patients, but this number is probably underestimated. Routine laparoscopy is not required. However, all patients need further monitoring due to a higher risk of endometriosis. Based on the analyzed studies and our case series, vaginal septectomy is a sufficient surgical technique to relieve symptoms and prevent possible complications in most OHVIRA patients.

28 years of functioning of the ileal ureter - own experience and systematic review

A SHORT INTRODUCTION

Irreversible ureteral damage is a rare and challenging problem for pediatric urologists. Ileal replacement has become one of the limited surgical options for ureteral reconstruction. Only a few papers have examined the results of the ileal ureter and renal function outcomes. Furthermore, there are even fewer papers showing patients with the intestinal ureter, which is used to drain urine from a solitary kidney in early childhood.

AN OBJECTIVE

To perform a systematic review and analyze available cases of the long-term function of the "neoureter" and differences in the surgical approach. To present the case of a 29-year-old female with a history of ileal replacement of the ureter in a solitary kidney which was performed in this patient at the age of 14 months.

STUDY DESIGN

PubMed and Scopus were used to search for eligible articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were strictly followed. Based on the titles, abstracts, and full-text reviews, 77 articles were analyzed, of which only 23 were directly related to pediatric cases of our interest. Medical records of the female patient, who has been treated in our center since 1991, were retrospectively described and reviewed.

RESULTS

Of 23 papers, we identified 75 cases of children who underwent ureteral substitution. The outcomes of the procedure are satisfactory and acceptable. The presented case of the female patient shows a good therapeutic option.

CONCLUSION

Ileal ureteral reconstruction is a safe and effective therapeutic option (even in a long-term follow-up). Despite many problems and complications, it allows preservation of renal and bladder function and social dryness.

A Novel Intronic Splice-Site Mutation of the CYP11A1 Gene Linked to Adrenal Insufficiency with 46,XY Disorder of Sex Development

A novel CYP11A1: c.1236 + 5G > A was identified, expanding the mutation spectrum of the congenital adrenal insufficiency with 46,XY sex reversal. In a now 17-year-old girl delivered full-term (G2P2, parents unrelated), adrenal failure was diagnosed in the first year of life based on clinical picture of acute adrenal crisis with vomiting, dehydration, weight loss, hypotension, and electrolyte disturbances. At the time, hormonal tests revealed primary adrenocortical insufficiency and steroid profiles showed lack of products of steroidogenesis, and since then the patient has been treated with substitution doses of hydrocortisone and fludrocortisone. At the age of 14, considering the absence of puberty symptoms, extended diagnostic tests revealed elevated LH levels (26.5 mIU/mL) with pre-puberty FSH levels (4.9 mIU/mL), low estradiol (28 pmol/L), testosterone (<2.5 ng/mL), and extremely high levels of ACTH (4961 pg/mL). A cytogenetic study revealed a 46 XY karyotype. A molecular examination confirmed the missense mutation and a novel splice-site mutation of CYP11A1 gene. Compound heterozygosity for the CYP11A1 gene with a known pathogenic variant in one allele and a novel splice site mutation in the second allele is most probably responsible for congenital adrenal insufficiency with 46,XY sex reversal. We discuss the necessity of cytogenetic test in the case of early onset of adrenal failure in the absence of steroidogenesis metabolites in the steroid profile.

A rare case of primary amenorrhoea and breast development in a 46,XY 15-year-old girl

A disorder of sex development (DSD) is defined as a congenital condition in which development of chromosomal, gonadal, or anatomical sex is atypical. Swyer syndrome is an example of 46,XY DSD with a female phenotype. It usually becomes apparent in adolescence with delayed puberty and amenorrhoea. Spontaneous breast development is very rare. A 15-year-old girl was presented due to primary amenorrhoea with breast development compatible with Tanner stage V. Hormonal tests revealed hypergonadotropic hypogonadism with low level of oestradiol. Pelvic ultrasound and magnetic resonance imaging revealed a small uterus, and no ovaries were found. In the right lower abdomen, a structure of unknown origin was visible. The chromosome analysis revealed a 46,XY karyotype. The patient was qualified for a laparoscopic bilateral gonadectomy. Postoperative histopathological examination revealed gonadoblastoma. We underline the need to consider DSD 46,XY in the presence of primary amenorrhoea, even when pubertal development is present. Germ cell tumors have a tendency to grow and metastasize rapidly. Delayed diagnosis may increase the risk of malignant transformation and cause a poor diagnosis.

Spontaneous recovery from uncomplicated acute appendicitis

Background: Historically, acute appendicitis requires surgical treatment. In recent years, there has been an increased interest in treating uncomplicated cases in a conservative way. The development in radiological and laboratory diagnosis has allowed for better possibilities of identification and watchful waiting of simple appendicitis. Objectives: The aim of the study was a retrospective evaluation of the efficacy of conservative treatment of uncomplicated acute appendicitis in children diagnosed based on clinical, laboratory and sonographic signs. Materials and methods: The diagnosis of uncomplicated acute appendicitis was based on the clinical signs, laboratory tests and ultrasound findings. Two clinical criteria, one laboratory criterion and two sonographic criteria, were assumed as a clear diagnosis of appendicitis. the retrospective assessment was conducted among 382 children who were hospitalised for suspected appendicitis. In those we identified a group of 66 children who met the criteria of acute appendicitis. The efficacy of conservative treatment in patients who met the criteria mentioned above was evaluated. Results: Within the period of at least one year, 89.4% of patients (59/66) were not re-hospitalised for recurrent symptoms. Eventually, 92.4% of patients (61/66) included in the study did not require surgical treatment. Conclusion: Uncomplicated acute appendicitis should be initially treated conservatively with watchful waiting. The vast majority of uncomplicated appendicitis cases can resolve spontaneously.

Perinatal hospice care in the opinion of nurses and midwives

OBJECTIVES

Perinatal medicine is a relatively new, dynamically developing branch of medicine. Its main purpose is taking care of a woman in the pre-conception period, pregnancy and delivery, as well as taking care of a newborn baby. The main aim of the study was to assess the state of knowledge and opinion on hospice perinatal care of professionally active nurses and midwives.

MATERIAL AND METHODS

An original and anonymous questionnaire containing 30 questions was used for the study. 572 nurses and midwives from the Silesian Voivodeship took part in the study. The obtained data were analyzed.

RESULTS

Only 31.6% of respondents defined the level of their knowledge of pregnancy and neonatal care as high. 12.8% of respondents were able to indicate the definition of perinatal care and accurately determine its goals. The women participating in the study were in favor of enclosing the information about not attempting resuscitation (DNAR) in medical record of children with incurable disease diagnosed in fetal life (99.3%).

CONCLUSIONS

The study showed deficits in practical and theoretical knowledge of nurses and midwives in the area of hospice perinatal care. Lack of proper preparation is also one of the most frequently mentioned difficulties in taking care of a child and family with poor prognosis.

Early Feminizing Genitoplasty in Girls with Congenital Adrenal Hyperplasia (CAH)-Analysis of Unified Surgical Management

AIM

To analyze a single-centre experience in feminizing genitoplasty in virilized girls with congenital adrenal hyperplasia (CAH).

METHODS

Review of medical records of all 46, XX CAH patients undergoing single stage feminizing genitoplasty between 2003 and 2018 was performed.

RESULTS

A total of 31 girls aged from 4 months to 10 years were included in the study. The majority (n = 26/31, 84%) were operated before 2 years of age (median 8 months). External virilization was rated as Prader 3 (n = 7/31), Prader 4 (n = 21/31) and Prader 5 (n = 3/31). The urethrovaginal confluence location was low in 19 and high in 12 girls with a percentage distribution similar in Prader 4 and 5 (p > 0.05) but significantly different in Prader 3 (p = 0.017). The follow-up ranged from 12 months to 15 years. All parents assessed the cosmetic result as satisfactory. Perioperative complications occurred in two patients and included rectal injury (n = 1/31) and prolonged bleeding (n = 1/31). Three patients developed late complications including labial atheromas (n = 2/31) and vaginal stricture requiring surgical dilatation (n = 1/31). Low confluence did not decrease the risk of complications.

CONCLUSIONS

Early feminizing genitoplasty in girls with congenital adrenal hyperplasia, irrespective of virilization severity, gives satisfactory cosmetic results and is characterized by low and acceptable surgical risk. Nevertheless, the most important determinant of the effectiveness of such management would be future patients' satisfaction.

No Appendix is Too Short-Simultaneous Mitrofanoff Catheterizable Vesicostomy and Malone Antegrade Continence Enema (MACE) for Children with Spina Bifida

OBJECTIVE

To present the results of simultaneous creation of both Mitrofanoff stoma and Malone antegrade continence stoma (MACE) using simple division of the appendix and a cecal extension method.

MATERIALS AND METHODS

Between June 2011 and November 2016, simultaneous Mitrofanoff and MACE was performed in 16 children (12 children-simple division of the appendix, 4 children-appendicovesicostomy and cecal extension of the appendix). Extension of the appendix was achieved by tubularization of the excised cecal flap next to the short appendicular stump. The new extended channel was then wrapped by cecal wall.

RESULTS

Follow-up was 40 months (10-74 months). Currently, in all children, both stomas are easily catheterizable. Obstruction of MACE occurred in 5 children (4 with split appendix, 1 with extended appendix); Mitrofanoff stomal stenosis occurred in 1 child. Endoscopic revision and prolonged catheterization of stenotic stomas were effective in all cases. Wound infection and dehiscence was noted in 2 children (both with split appendix). Drainage and intravenous antibiotics were effective. All Mitrofanoffs are continent. In 4 children there is incident minor leakage of the MACE (3 with split appendix and in 1 with extended appendix).

CONCLUSION

The split appendix procedure is feasible. Cecal extension of the appendix seems to be a good option when the appendix is too short for a simple split procedure.

Late-Onset Puberty Induction by Transdermal Estrogen in Turner Syndrome Girls-A Longitudinal Study

OBJECTIVE

Estrogen replacement therapy (ERT) for Turner syndrome (TS) is a widely discussed topic; however, the optimal model of ERT for patients with delayed diagnosis and/or initiation of therapy is still unclear, mainly due to insufficient data. We present the results of a prospective observational single-center study in which the efficacy of late-onset puberty induction by one-regimen transdermal ERT in TS girls was evaluated.

METHODS

The analysis encompassed 49 TS girls (63.3% with 45,X) with hypergonadotropic hypogonadism in whom unified transdermal ERT protocol was used for puberty induction (first two months 12.5 μg/24 h, thereafter 25.0 μg/24 h until breakthrough bleeding). Clinical visits for examination and therapy modification took place every 3-6 months. Transabdominal pelvic ultrasound examinations were performed at least twice: at the beginning and at the end of follow-up.

RESULTS

The mean (SD) age at ERT induction was 15.1 (1.3) years. The duration of follow-up was 2.4 (1.1) years. Half of all the patients had at least B2 after 0.57 years, B3 after 1.1 years, B4 after 1.97 years, and menarche after 1.82 years from ERT initiation. With earlier initiation of ERT (≤14 years), B2 (p = 0.059) was achieved faster and B4 (p = 0.018) significantly slower than with the later start of ERT. Thirty-four (94.4%) patients had at least stage B3 at menarche. The karyotype, initial weight, and body mass index had no impact on puberty tempo during ERT. The uterine volume increased significantly during ERT in all the study group (p < 0.0001), and in half of the patients, the increase was at least 12.4-fold. It did not correlate with the duration of treatment (p = 0.84) or the dose of estradiol per kilogram (p = 0.78), nor did it depend on karyotype (p = 0.71) or age at ERT initiation (p = 0.28). There were no differences in ΔhSDS during ERT (p = 0.63) between the two age groups (ERT ≤14 and >14 years).

CONCLUSION

The presented easy-to-use fixed-dose regimen for late-onset puberty induction allowed for a satisfactory rate of achieving subsequent puberty stages and did not influence the growth potential.

Babies with myelomeningocele in Poland: parents' attitudes on fetal surgery versus termination of pregnancy

BACKGROUND

Recent surgical advances have resulted in fetal surgery becoming an option for children with myelomeningocele (MMC). However, there is little information about the parents' attitudes towards such therapy.

METHODS

Following a lecture on the current status and problems of fetal surgery for MMC, a 12-item questionnaire was administered to 58 parents of children with MMC. Questionnaire topics included knowledge of the disease and treatment options, as well as attitudes and concerns towards fetal surgery or termination of pregnancy.

RESULTS

Following the lecture, 14 (out of 58) parents felt that knowledge of the disease would allow for abortion to be an option, while 18 were uncertain. Once informed of potential risks and benefits of fetal surgery, 34 parents had a positive or rather positive attitude towards this procedure.

CONCLUSIONS

On the basis of these results, it was concluded that this population is potentially interested in the use of fetal surgery.

Quadruplication of dystopic kidney in combination with ureteral cyst

A case of ureteral quadruplication associated with renal dystopia is described. Four ureters drained into ureteric cyst and distal monoureter opened into the bladder. The literature concerned this extremely rare malformation is reviewed.

Ureteral triplication--report of four cases

Four cases of ureteral triplication in children are described. In one case ureteral triplication was detected incidentally and it was not accompanied by any other pathology of the urinary tract. In the three remaining cases there were pathologies of the urinary system (reflux, obstruction) that demanded surgical treatment. The literature concerning this rare anomaly is reviewed.

Results of Nuss procedures for the correction of pectus excavatum

INTRODUCTION

The principle of the Nuss procedure is remodulation of the chest using a steel bar inserted by means of two small skin incisions along the axillary lines.

PURPOSE OF THE STUDY

The assessment of the outcome after treatment.

MATERIAL AND METHODS

Between July 1998 and March 2003 66 children were operated on by Nuss technique to correct pectus excavatum in our department. Age ranged from 1 to 19 years (mean 11.8 years). The evaluation prior to surgery included chest X-ray and CT, pulmonology consultation with pulmonary function tests and cardiology consultation. We used a modified technique in which we inserted the supporting bar directly from the right side, with no thoracoscope, no sharp tools and no guiding tape. Intrapleural or epidural bupivacaine was used for postoperative pain control.

RESULTS

Duration of the operation was between 20 and 60 min. Complications included wound infections in six children, haemothorax in three and pneumonia in one. In 56 children the early cosmetic results were very good. In 5 children the excavation of the lower part of the sternum has persisted, in 5 children the excavation of the sternum was corrected but asymmetric thickening in the parasternal region persisted. In all cases the results were satisfactory for both the children and their parents. In 24 children the supporting bar was removed two years after the first operation. Postoperative courses were uneventful and the cosmetic results were good. In one child we observed a recurrence of the deformity six months after bar removal.

CONCLUSIONS

The early results of the new operation for pectus excavatum are good in most children. The minimal invasiveness of this method suggests that this procedure is indicated in cases where the defects are only cosmetic.

[Diagnostics and treatment of chronic constipation in children--the experience of the department of paediatric surgery]

The chronic constipation in children can pose a big problem both in pediatric and surgical practice. The purpose of this work is to present diagnostic and treatment procedures in children with chronic constipation. For over three years 70 children with defecation problems have been referred to the Department of Pediatric Surgery in Katowice (Poland). As a result of diagnostic procedures (anorectal manometry, barium enema and rectal biopsy) Hirschsprung disease was diagnosed in 21 cases and chronic constipation in 49. Children with Hirschsprung disease were treated surgically. Children with diagnosed chronic constipation were treated conservatively (cleansing enemas, oral laxatives, diet) and good results were obtained in 30 patients. 19 children underwent anal divulsion and 16 improved. In 2 cases sphincter myotomy was performed and good result was obtained in both of them. The diagnostics and treatment of chronic constipation in pediatric surgical ward is advantageous, because: Hirschsprung disease can be excluded, cleansing of colon sometimes requires general anesthesia and in selected cases surgical procedure is necessary.

[Our experiences in the surgical treatment of vesico-ureteral reflux]

In the years 1995-1997 18 patients (20 ureters) were treated by modified Lich Gregoir's technique for vesicoureteral reflux. In this group 3 children had neurogenic bladder. The age of the patients was 2-18 years, on an average 10 years. In the group of operated ureters there were three with reflux grade II, six-grade III, eight-grade IV and three-grade V. Postoperative period was uneventful in all cases. Control imaging studies (voiding cystourethrography and intravenous pyelography) were done after 8-18 months. These studies were performed in 15 patients. In 14 cases complete resolution of the reflux was found and in one case the improvement from grade III to I. No operated child had stricture of the ureterovesical junction and urinary retention in upper urinary tract. In our opinion extravesical modified Lich-Gregoir's antireflux procedure is effective method, with low probability of complication and less aggressive for patients in comparison to intravesical procedures.
