Ultrawide Dark Solitons and Droplet-Soliton Coexistence in a Dipolar Bose Gas with Strong Contact Interactions.

We look into dark solitons in a quasi-1D dipolar Bose gas and in a quantum droplet. We derive the analytical solitonic solution of a Gross-Pitaevskii-like equation accounting for beyond mean-field effects. The results show there is a certain critical value of the dipolar interactions, for which the width of a motionless soliton diverges. Moreover, there is a peculiar solution of the motionless soliton with a nonzero density minimum. We also present the energy spectrum of these solitons with an additional excitation subbranch appearing. Finally, we perform a series of numerical experiments revealing the coexistence of a dark soliton inside a quantum droplet.

Using Adaptiveness and Causal Superpositions Against Noise in Quantum Metrology.

We derive new bounds on achievable precision in the most general adaptive quantum metrological scenarios. The bounds are proven to be asymptotically saturable and equivalent to the known parallel scheme bounds in the limit of a large number of channel uses. This completely solves a long-standing conjecture in the field of quantum metrology on the asymptotic equivalence between parallel and adaptive strategies. The new bounds also allow us to easily assess the potential benefits of invoking nonstandard causal superposition strategies, for which we prove, similarly to the adaptive case, the lack of asymptotic advantage over the parallel ones.

Long-term weight loss after bariatric procedures for morbidly obese adolescents and youth: a single-institution analysis with up to 19-year follow-up.

BACKGROUND: Obesity is a public health concern among adolescents and young adults. Bariatric surgery is the most effective treatment for morbid obesity and has been increasingly utilized in young patients. Long-term outcomes data for bariatric surgery in this age group are limited. METHODS: This is a single-institution, prospective analysis of 167 patients aged 15-24 years who underwent one of three laparoscopic bariatric procedures between 2001 and 2019: Roux-en-Y gastric bypass (LRYGB, n = 71), adjustable gastric banding (LAGB, n = 22), and sleeve gastrectomy (LSG, n = 74). Longitudinal weight and body mass index (BMI) measurements were compared to evaluate patterns of weight loss. RESULTS: All operations were completed laparoscopically using the same clinical pathways. Patients were predominantly female (82.6%), had a median age of 22.0 [Q1-Q3 20.0-23.0] years, and had a mean presurgical BMI of 48.5 ± 6.5 kg/m2 (range 38.4-68.1 kg/m2). All procedures produced significant weight loss by 1 year, peak weight loss by 2 years, and modest weight regain after 5 years. Mean percent weight/BMI losses at 5 years for LRYGB, LAGB, and LSG were - 36.7 ± 10.8%, - 14.5 ± 15.3%, and - 25.1 ± 13.4%, respectively (p < 0.001). LRYGB patients were most likely to achieve ≥ 25% weight loss at 1, 3, and 5 years and maintained significant average weight loss for more than 15 years after surgery. Reoperations were procedure-specific, with LAGB, LRYGB, and LSG having the highest, middle, and lowest reoperation rates, respectively (40.9% vs. 16.9% vs. 5.4%, p < 0.001). CONCLUSION: All procedures provided significant and durable weight loss. LRYGB patients achieved the best and most sustained weight loss. LSG patients experienced second-best weight loss between 1 and 5 years, with lowest chance of reoperation. LAGB patients had the least weight loss and the highest reoperation rate. Compared to other factors, type of bariatric procedure was independently predictive of successful weight loss over time. More studies with long-term follow-up are needed.

"Floating ball sign" in the diagnostic imaging of mature ovarian teratomas in children.

The "floating ball sign" (FBS) is a rarely described visual phenomenon found in mature ovarian teratoma imaging. It is characterized by the presence of movable, spherical areas within the cystic component of a tumor. Such visualization is possible both in cross-sectional imaging and ultrasonography. To evaluate the incidence of FBS in the pediatric population with regard to patients' age and tumor size. This is a retrospective study of pediatric patients operated on in a tertiary pediatric surgical center between January 2009 and December 2022 due to mature ovarian teratoma; the medical records were reviewed for the age at diagnosis, recurrences, tumor size, and their characteristics in preoperative imaging. Eighty-three patients (mean age 14, range 0-17) out of 91 met the inclusion criteria for the analysis. Eighty-seven operations on 90 ovaries were performed. Preoperatively 38 patients underwent CT, 13 MRI, and 39 received only the ultrasound examination. The FBS was identified in preoperative imaging diagnostics in 3 (3.3%) girls (14, 16 and 17 years of age). The average largest tumor dimension and volume were 142 mm and 1268 cc in the FBS group, and 73 mm and 252 cc in the remaining group, respectively. FBS tumors usually reach large sizes. Although the sign is rare in children, there are no scientific reports of its occurrence in the first life decade. Color flow mapping and cross-sectional imaging play a pertinent role in distinguishing this uncommon pattern from a malignant mass and enable the selection of an appropriate surgical approach.

Multiple-Phase Quantum Interferometry: Real and Apparent Gains of Measuring All the Phases Simultaneously.

We characterize operationally meaningful quantum gains in a paradigmatic model of lossless multiple-phase interferometry and stress the insufficiency of the analysis based solely on the concept of quantum Fisher information. We show that the advantage of the optimal simultaneous estimation scheme amounts to a constant factor improvement when compared with schemes where each phase is estimated separately, which is contrary to widely cited results claiming a better precision scaling in terms of the number of phases involved.

Quantum Metrology of Noisy Spreading Channels.

We provide the optimal measurement strategy for a class of noisy channels that reduce to the identity channel for a specific value of a parameter (spreading channels). We provide an example that is physically relevant: the estimation of the absolute value of the displacement in the presence of phase randomizing noise. Surprisingly, this noise does not affect the effectiveness of the optimal measurement. We show that, for small displacement, a squeezed vacuum probe field is optimal among strategies with same average energy. A squeezer followed by photodetection is the optimal detection strategy that attains the quantum Fisher information, whereas the customarily used homodyne detection becomes useless in the limit of small displacements, due to the same effect that gives Rayleigh's curse in optical superresolution. There is a quantum advantage: a squeezed or a Fock state with N average photons allow to asymptotically estimate the parameter with a sqrt[N] better precision than classical states with same energy.

Strongly Correlated Quantum Droplets in Quasi-1D Dipolar Bose Gas.

We exploit a few- to many-body approach to study strongly interacting dipolar bosons in the quasi-one-dimensional system. The dipoles attract each other while the short range interactions are repulsive. Solving numerically the multiatom Schrödinger equation, we discover that such systems can exhibit not only the well-known bright soliton solutions but also novel quantum droplets for a strongly coupled case. For larger systems, basing on microscopic properties of the found few-body solution, we propose a new equation for a density amplitude of atoms. It accounts for fermionization for strongly repelling bosons by incorporating the Lieb-Liniger energy in a local density approximation and approaches the standard Gross-Pitaevskii equation (GPE) in the weakly interacting limit. Not only does such a framework provide an alternative mechanism of the droplet stability, but it also introduces means to further analyze this previously unexplored quantum phase. In the limiting strong repulsion case, yet another simple multiatom model is proposed. We stress that the celebrated Lee-Huang-Yang term in the GPE is not applicable in this case.

π-Corrected Heisenberg Limit.

We consider the precision Δφ with which the parameter φ, appearing in the unitary map U_{φ}=e^{iφΛ}, acting on some type of probe system, can be estimated when there is a finite amount of prior information about φ. We show that, if U_{φ} acts n times in total, then, asymptotically in n, there is a tight lower bound Δφ≥π/[n(λ_{+}-λ_{-})], where λ_{+}, λ_{-} are the extreme eigenvalues of the generator Λ. This is greater by a factor of π than the conventional Heisenberg limit, derived from the properties of the quantum Fisher information. That is, the conventional bound is never saturable. Our result makes no assumptions on the measurement protocol and is relevant not only in the noiseless case but also if noise can be eliminated using quantum error correction techniques.

Pachydermodactyly - a report of two cases.

Pachydermodactyly (PDD) is a rare and benign form of digital soft tissues fibromatosis, which affects the skin of the fingers. The disorder is characterized by asymptomatic, symmetric, progressive soft tissue swelling of the proximal interphalangeal (PIP) joints of the fingers. The etiology of disease remains unknown. It is usually acquired, even though there are some publications that document family cases. It affects mainly adolescent men. We report two boys with the bilateral swelling of the of the PIP joints of the fingers and skin and subcutaneous tissue thickening. Based on clinical manifestations, radiological study and histopathological examination, pachydermodactyly was diagnosed. PDD is a rare and benign disorder, although it is important to consider other diseases, especially rheumatic conditions, in the differential diagnosis in order to avoid unnecessary additional tests and treatments.

Twiddler syndrome in a patient with tremor dominant Parkinson's disease. A case report and literature review.

Twiddler syndrome is described as a spontaneous rotation or intentional external manipulation of implanted cardiac or occasionally deep brain stimulation (DBS) devices. We report this hardware related complication in a patient with tremor dominant Parkinson's disease (PD), who underwent unilateral subthalamic nucleus (STN) DBS and subsequently developed twiddler syndrome. The clinical course of twiddler syndrome in this patient is described. Some surgical nuances which may prevent its occurrence are suggested. Our case report indicates that twiddler syndrome occurs in DBS patients. Impedance check of DBS hardware, plain chest X-ray, or palpation for a knobbly extension lead through the skin above the IPG allows the correct diagnosis and subsequently a prompt surgical revision. Our subsequent literature review revealed only 10 patients with twiddler syndrome in DBS patient population worldwide. This number may suggest that this syndrome may be unrecognized or underreported, given the number of patients with movement disorders implanted with DBS hardware worldwide.

Ultrasound-Histopathological Presentation of Thyroid and Ovary Lesions in Adolescent Patients with DICER1 Syndrome: Case Reports and Literature Overview.

BACKGROUND: DICER1, a cancer predisposition syndrome (CPS), seems to escape timely diagnosis in pediatric patients. Case report 1: A 16-year-old female patient was referred to the endocrinology ward due to a large goiter. Her medical history indicated normal sexual maturation, with menarche occurring at 13.5 years. Over the past 2.5 years, she had developed pronounced androgenic symptoms, including a deepened male voice; facial, back, and neckline acne; hirsutism; and menstrual irregularities leading to secondary amenorrhea. A thyroid ultrasound identified a multinodular goiter (MNG) with cystic-solid lesions containing calcifications. An abdominal ultrasound identified a 5.7 × 6.9 cm solid mass in the right adnexal region, displacing the uterus to the left. Histopathological examination confirmed a Sertoli-Leydig cell tumor. The patient was subjected to a total thyroidectomy. Histopathology revealed benign follicular cell-derived neoplasms. Thyroid follicular nodular disease (TFND) was diagnosed bilaterally. DNA analysis using NGS, confirmed via the Sanger method, revealed a pathogenic heterozygotic variant c.2953C>T [p.Gln985*] in exon 18 of the DICER1 gene. Case report 2: A 12-year-old male patient was admitted to the pediatric surgery unit due to a 33 mL goiter. A month prior to his admission, the patient discovered a palpable nodule in his neck, accompanied by hoarseness. An ultrasound revealed MNG. Molecular analysis revealed a pathogenic heterozygotic variant c.2782C>T [p.Gln928*] in exon 17 of the DICER1 gene. Subsequently, a total thyroidectomy was performed, and histopathological examination revealed TFND bilaterally. CONCLUSIONS: Recent advances in genetic evaluation and in histological approaches indicate that MNG/TFND, although rare in the pediatric population, when accompanied by characteristic ultrasound and histopathological features, and by additional features such as androgenization, may warrant assessment also of the DICER1 gene within CPS molecular panel screening.

Ultrasound evolution of parenchymal changes in the thyroid gland with autoimmune thyroiditis in children prior to the development of papillary thyroid carcinoma - a follow-up study.

Background: Follicular cell-derived thyroid carcinoma represents the vast majority of paediatric thyroid cancers (TCs). Papillary thyroid carcinoma (PTC) accounts for over 90% of all childhood TC cases, and its incidence in paediatric patients is increasing. The objective of this follow-up study was to present the outcome of ultrasound (US) and laboratory monitoring of paediatric patients with autoimmune thyroiditis (AIT) prior to the development of PTC. Patients and methods: This prospective study included 180 children and adolescents (132 females; 73.3%) with a suspicion of thyroid disorder referred to the Outpatient Endocrine Department. The patients were divided into four groups: 1) 28 patients with a mean age of 10.7 [standard deviation (SD), 3.1] y, in whom PTC was detected during the active surveillance of AIT [AIT(+), PTC(+) follow up (F)]; 2) 18 patients with a mean age of 12.8 (SD, 3.4) y, in whom PTC and AIT were detected upon admission (A) [AIT(+), PTC(+) A]; 3) 45 patients with a mean age of 13.0 (SD, 3.4) y, in whom PTC was detected upon admission and AIT was excluded [AIT(-), PTC(+) A]; and 4) an age- and sex-matched control group of 89 patients with AIT and with a mean age of 9.4 (SD, 3.0) y. The analysis included clinical, US, and laboratory assessment results of children on admission (groups 1-4) and during follow-up (groups 1 and 4) in the Paediatric Endocrine Outpatient Department. Results: Upon admission of those in group 1, the US evaluation revealed a hypoechogenic thyroid gland in 12 and an irregular normoechogenic gland in 16 patients. US monitoring revealed an increase in thyroid echogenicity and an increased irregularity of the thyroid structure during the follow-up period of all of the patients from group 1. Such changes were not noticed in group 4. PTC was diagnosed at the mean time of 3.6 y (3 mo-9 y) since AIT confirmation in group 1. The mean maximum PTC diameter as per the US was significantly smaller in group 1 than in groups 2 and 3 [13.2 (10.8) mm vs. 22.2 (12.8) and 22.05 (15.4) mm]. Fewer patients in group 1 were referred to 131I than in groups 2 and 3 (71.4% vs. 94.4 and 93.3%). Interestingly, significant differences were observed in the thyroglobulin antibody (TgAb)/thyroid peroxidase antibody (TPOAb) ratio between groups 2 and 3, as opposed to group 4, at the beginning of observation [15.3 (27.6) and 3.5 (8.8] vs. 0.77 (1.9)]. In group 1, after the follow-up, an increase in the TgAb/TPOAb ratio was observed [1.2 (9.8) to 5.2 (13.5)]. There were no significant differences between groups 1-3 in labeling index Ki67, lymph nodes metastasis, extrathyroidal extension, and angioinvasion. There were no associations between thyroid-stimulating hormone, TgAb, and the extent of the disease. Conclusion: The use of thyroid US focused on the search for developing tumours in the routine follow-up of patients with AIT may not only help in the early detection of thyroid malignancies that are not clinically apparent but may also influence the invasiveness of oncological therapy and reduce the future side effects of 131I therapy. We propose that the repeat evaluation of TPOAb and TgAb warrants further exploration as a strategy to determine TC susceptibility in paediatric patients with AIT in larger multicentre studies.

Ultrasound, laboratory and histopathological insights in diagnosing papillary thyroid carcinoma in a paediatric population: a single centre follow-up study between 2000-2022.

Background: Papillary thyroid carcinoma (PTC) often coincides with autoimmune thyroiditis (AIT); whether this association is incidental or causal remains debated. Objective: To evaluate the ultrasonographic, laboratory, and histopathological features of PTC in paediatric patients with and without AIT and its relationship to puberty. Design: A retrospective cohort study. Patients and methods: A retrospective analysis of medical records of 90 patients (69; 76.7% females). The mean age at PTC diagnosis was 13.8 years [range 6-18]. All patients were evaluated ultrasonographically before thyroid surgery. Thyroid nodules were categorised using the European Thyroid Imaging Reporting and Data System (EU-TIRADS PL), and cytopathology was assessed using Bethesda criteria. Neck ultrasound results and thyroid and autoimmune status were correlated with histopathological PTC assessment. Results: The coexistence of PTC and AIT was found in 48.9% (44/90) of patients. The percentage of AIT was increasing with age; AIT was present only in 1/3 of prepubertal, close to 50% in pubertal, and over 60% in adolescent patients. The youngest patients (aged <10 years old) presented more often with goitre and lymphadenopathy and less often with AIT than adolescents (15-18 years of age). There were no differences in TPOAb, TgAb, and TSH levels between the age subgroups. Presurgical TgAb levels were higher than those of TPOAb in the youngest patients. Histopathological analysis revealed that the solid subtype was observed more often in prepubertal children and diffuse sclerosing in children below 14 years of age, whereas the classic subtype dominated in late pubertal. Univariate and multivariate analyses revealed that lymph nodes metastases (LNM) were associated with PTC diameter and fT4 level, whereas extrathyroidal extension with age and angioinvasion with PTC diameter and age. The correlations between age and fibrosis, and the presence of psammoma bodies in malignant tissues were close to significant. We did not observe an association between TSH levels and the presence of autoimmunity and PTC variables. Conclusions: In paediatric patients the natural course of PTC may be less aggressive in adolescent patients than in younger children (especially < 10 years of age). We suggest that pre-operative evaluation of paediatric patients with thyroid nodules could include apart from assessment of thyroid hormones, evaluation of TPOAb, TgAb, and TRAb together with comprehensive neck ultrasonography.

Guidelines for treatment of esophageal atresia in the light of most recent publications.

INTRODUCTION: Esophageal atresia is a congenital anomaly well known in the community of pediatric surgeons. Nonetheless some aspects of management remain vague and societies of gastroenterologists as well as surgeons have been gathering to determine pertinent ways to handle this condition. To make ground for unification, the guidelines of some most important societies were compared and gathered in one review. MATERIALS AND METHODS: Literature review of online databases of the PubMed and the Cochrane Library with (o)esophageal atresia, guidelines and follow-up used as keywords. RESULTS: Over the course of the last few years there was a lot of effort invested in making clear and accurate guidelines for management of EA, largely with good results. In the majority of important matters, opinions of specialists were consistent or complementary to each other. Because some of them described different phases of management, gathering them together led to obtaining the wider picture, which can help pediatric surgeons in making decisions while treating the patients with EA. CONCLUSION: There is a necessity for careful following guidelines which have been changing quite fast along with new significant publications about EA. Some concerns remained debatable and their accentuation in this review was made to bring awareness to vague issues, such as postoperative antibiotic prophylaxis or duration of administering PPI. Additionally structured follow-up programs for the first 18 years and after reaching maturity should be made.

Recommendations of procedures to follow in the case of ovarian lesions in girls.

This study presents current recommendations of the Polish Association of Pediatric Surgeons (PTChD) regarding diagnostics and treatment of ovarian lesions in girls. They are based on many years of the authors' clinical experience as well as a review of international literature and include practical clinical guidelines. The recommendations were formulated in cooperation with the Polish Association of Pediatric Oncology and Hematology (PTOHD), Polish Pediatric and Adolescent Gynecology Section of the Polish Society of Gynecologists and Obstetricians (PTG) and Polish Pediatric Section of the Polish Society of Radiology (PLTR). Only better understanding of prepubertal ovarian biology and natural history of its pathology may help to introduce efficient and safe diagnostic and therapeutic strategies for girls. The prepared document has been supplemented with treatment algorithms.

What Should Be the Topics of a Prospective Study on Ovarian Masses in Children?-Results of a Multicenter Retrospective Study and a Scoping Literature Review.

PURPOSE: to determine management problems of ovarian masses in girls in order to form a baseline for prospective randomized studies of the established topics and quality improvement of our management. MATERIALS AND METHODS: We performed a national analysis of clinical aspects of ovarian masses in girls operated on in Poland, analyzed retrospectively medical files of all consecutive patients aged 0-18 who underwent surgeries for ovarian lesions between 2012 and 2017 at 17 pediatric surgical departments and complemented the analysis with a scoping review of a recent primary research related to ovarian masses in children. RESULTS: The study group comprised 595 patients. Forty-four (7.39%) girls were diagnosed with malignant tumors. The overall preservation rate was 64.54%. The analysis revealed that positive tumor markers (OR = 10.3), lesions larger than 6 cm (OR = 4.17) and solid mass on ultrasound examination (OR = 5.34) are interdependent variables differentiating malignant tumors from non-malignant lesions (X42 = 79.1; p = 0.00000). Our scoping review revealed 10 major branches of research within the topic of ovarian masses in pediatric population. CONCLUSIONS: We have developed an overview of the field with the emphasis on the local environment. Our next step is a multi-institutional prospective study of a quality improvement project implementation based on the obtained knowledge.

Laparoscopic histological mapping for the determination of the length of aganglionic segment in children with Hirschsprung disease.

BACKGROUND: Modern approach to the surgical treatment of Hirschsprung's disease (HD) consists in the earliest possible repair and reduction of the number of surgical interventions. Primary one-stage transanal endorectal pull-through (TEPT) technique requires preoperative determination of the length of aganglionic segment. The efficacy of the standard method - contrast enema - is questionable in patients with a poorly defined transitional zone. OBJECTIVES: To present the proposed laparoscopic method for the management pathway in patients with HD, in whom the determination of the length of aganglionic segment with contrast enema was not possible. MATERIAL AND METHODS: A retrospective analysis of the diagnostic and therapeutic management employed in 14 patients, from 2 weeks to 55 months of age, with diagnosed HD, treated between January 2013 and May 2020. Laparoscopic histological mapping was performed with the use of 3 laparoscopic ports of 3-5 mm diameter. RESULTS: In all patients, laparoscopic mapping allowed for the determination of the length of aganglionic segment and the mode of surgical treatment. Four children with determined short-segment disease underwent TEPT, while 2 underwent temporary colostomy formation using the Duhamel-Martin-Ikeda method. Five patients with long-segment HD underwent laparoscopic-assisted TEPT. One patient with long-segment disease was treated with a temporary double-barrel colostomy and definitive surgery was performed 3 months later using the Duhamel-Martin-Ikeda method. In 2 patients with an initial diagnosis of HD established using current diagnostic pathway, HD pathology was later excluded based on the results of laparoscopic mapping and repeat rectal suction biopsy. No complications related to the laparoscopic procedure were identified. CONCLUSIONS: The method of laparoscopic mapping is effective in the determination of the length of aganglionic segment in children with diagnosed HD. In doubtful cases, it can be the preferred option in establishing the final mode of surgical treatment.

Ovarian Sparing Surgery in Mature Ovarian Teratomas in Children: A 20-Year Single-Center Experience.

INTRODUCTION: Despite its benign nature, possible bilateral presentation, and a very good prognosis, ovarian sparing tumorectomy (OST) in mature ovarian teratoma (MOT) is not commonly performed. Unilateral oophorectomy has physiological consequences, while bilateral is devastating. The aim of this study is promotion of OST in MOT among children. MATERIALS AND METHODS: We reviewed 120 patients operated for MOT between August 1999 and 2019. RESULTS: Ovariectomy was performed in 15 patients (14 between 1999 and 2009 and 1 after 2010). In 105 girls, OST was possible including 32 with ovarian torsion. The approach was laparoscopy in 30 girls (11 conversions) and laparotomy in 94. Intra-abdominal spillage occurred in 30% of laparoscopic dissections. Postoperative morbidity was not associated with surgical approach (p = 0.613) or presence of adnexal torsion (p = 0,608). Follow-up was from 4 months to 9 years (median = 4 years) with access to 90% of patients. Bilateral lesions were observed in six (synchronous in five and metachronous in one) patients. Recurrence appeared in three patients operated via laparotomy and OST (after 12, 46, and 74 months). In one girl, asynchronous contralateral MOT was found 5 years after unilateral oophorectomy. Ovarian regeneration after torsion was observed in sonography in 84.4% of the patients. None of the patients experienced chemical peritonitis or malignant tumor transformation. CONCLUSION: OST is safe and effective and should be the first-line procedure in children. Laparoscopy and laparotomy constitute a complementary approach to MOT. Ultrasound follow-up is necessary to monitor recurrence, contralateral disease, and ovarian regeneration.

Adulthood of patients after oesophageal atresia repair- General Surgeon's Guide.

Introduction Despite proper surgical management in neonatal period, congenital oesophageal atresia [OA] may present serious source of lifelong disorders. The objective of our study is to present the most important facts about oesophageal atresia, types of treatment and possible complications which might demand surgical management in adult life. We would like to familiarize general surgeons with this matter to provide OA patients with proper medical care. Materials and Methods We made a thorough literature review of Medline database and Cochrane Library with "(o)esophageal atresia", "long gap", "surgery" and "follow-up" used as keywords. Results Long-term observation reveals that patients with OA may need help from general surgeons, however do not often look for it. Even after surgical repair in neonatal period, OA indispose to multiple concomitant disorders including gastroesophageal reflux disease, oesophagitis, strictures, epithelial metaplastic changes in the oesophagus or hiatal hernia development. Endoscopic follow-up should be systematically performed in OA patients' population in order to early detection of possible pathologies. Discussion Advancement in medicine allowed to improve survival rates and adulthood is reached more often in population of OA patients. In the face of variety of concomitant problems, systematic long-term follow-up seems to be crucial in proper medical care in these patients.
