RESUMEN

Over the past two decades, metal-organic frameworks (MOFs) have garnered substantial scientific interest across diverse fields, spanning gas storage, catalysis, biotechnology, and more. Zirconium, abundant in nature and biologically relevant, offers an appealing combination of high content and low toxicity. Consequently, Zr-based MOFs have emerged as promising materials with significant potential in biomedical applications. These MOFs serve as effective nanocarriers for controlled drug delivery, particularly for challenging antitumor and retroviral drugs in cancer and AIDS treatment. Additionally, they exhibit prowess in bio-imaging applications. Beyond drug delivery, Zr-MOFs are notable for their mechanical, thermal, and chemical stability, making them increasingly relevant in engineering. The rising demand for stable, non-toxic Zr-MOFs facilitating facile nanoparticle formation, especially in drug delivery and imaging, is noteworthy. This review focuses on biocompatible zirconium-based metal-organic frameworks (Zr-MOFs) for controlled delivery in treating diseases like cancer and AIDS. These MOFs play a key role in theranostic approaches, integrating diagnostics and therapy. Additionally, their utility in bio-imaging underscores their versatility in advancing medical applications.

RESUMEN

BACKGROUND: Invasive aspergillosis (IA) is an increasingly common and fatal opportunistic fungal infection in patients with haematological diseases. Early diagnosis is difficult as mycological culture techniques have low sensitivity and the radiological tools have low specificity. Galactomannan enzyme immunoassay (GEI) detects galactomannan in the human serum with a reported sensitivity and specificity between 30% and 100%. AIMS: The aim of this study was to analyse the role of GEI in diagnosis of IA in patients with febrile neutropenia and to evaluate the role of GEI in the diagnosis of IA as per the revised (2008) European Organization for Research and Treatment of Cancer-Mycoses Study Group (EORTC-MSG) criteria at two different optical density (OD) cut-offs of 0.5 and 1.0. SETTING: This prospective study was conducted in Safdarjung Hospital, New Delhi, India. METHODS: GEI testing was performed in adult patients of febrile neutropenia with evidence of IA. Results at two different OD indices (ODIs) of 0.5 and 1.0 were analysed. The evaluation of the diagnostic parameter, that is, GEI was measured in terms of sensitivity, specificity and positive and negative predictive value and was validated with the revised (2008) EORTC-MSG diagnostic criteria of IA. RESULTS: One hundred and eleven patients had evidence of IA, of which 79 patients were GEI positive when cut-off ODI was 0.5, whereas with cut-off ODI 1.0, 55 patients were GEI positive. CONCLUSION: ODI of 1.0 should be considered as positive while in patients with OD between 0.5 and 1.0, repeat sampling from the patient is recommended.

RESUMEN

Gastric teratoma is a very rare tumor, accounting for less than 1 % of all teratomas in infants and children. Melena or upper gastrointestinal tract bleeding in newborns and infants is a rare event and is usually caused by a benign lesion. Gastric teratoma has been reported as a cause of gastrointestinal bleeding on a few occasions. As gastric teratomas generally present as a palpable abdominal mass, more aggressive solid masses of childhood must be excluded. We present intramural extension of gastric teratoma presented as symptom of gastric outlet obstruction and melena.

RESUMEN

PURPOSE: Infantile haemangiomas comprise the majority of vascular anomalies and are considered the predominant vascular tumour type 1. We performed this prospective study to evaluate the therapeutic response and propranolol tolerance in infants with ulcerated infantile haemangioma of head and neck region. METHODS: Sixty-four patients with ulcerated infantile haemangiomas (IHs) of head and neck region, without any prior treatment and with age older than 1 month, were included in the study, after informed consent was obtained, and were randomly divided into groups A and B. Group A patients were given oral propranolol at a dose of 2 mg/kg per day in three divided doses as outpatients. Group B patients were given oral ibuprofen at a dose of 10 mg/kg 8-hourly and paracetamol at dose of 16.2 mg/kg 8-hourly. Documentation of gender, age, haemangioma location, duration of ulceration and pain was measured on the second and fifth day after commencement of treatment in both groups using the Children's Hospital of Eastern Ontario Pain Scale. RESULTS: There was no difference in pain score between the two groups (P value 0.074). Mean duration of healing of ulceration in group A was 17.93 ± 2.22 days and in group B was 27.71 ± 2.33 days (P value <0.001). In group A, out of 28 patients, 8 (28.5 %) were complete responders, 16 (57.1 %) were partial responders and 4 (14.2 %) were non-responders. CONCLUSION: Propranolol is a valuable therapeutic alternative for treatment of ulcerated haemangiomas and effectively reduces pain.

RESUMEN

OBJECTIVE: The posterior urethral diverticulum is a common urologic complication requiring reoperations in anorectal malformation cases (ARM). We present a series of 24 cases of male ARM managed without ligation of fistula. MATERIAL AND METHODS: A prospective study was conducted between July 2010 and June 2012 including male neonates with ARM, where rectobladder neck and rectoprostatic fistula were approached by the abdominal route. The fistulous tract was dissected to the distal-most possible length and was excised flush with the urethra without its ligation. A per-urethral catheter was placed in situ. A record was made of any features of urinary leak and a micturating cystourethrogram was performed at the 1-year of follow-up. RESULTS: Twenty-four cases of ARM, 16 with rectobladder neck fistula and eight cases with rectoprostatic fistula were included. Of these, 12 had single-stage primary abdominoperineal pull-through and 10 were managed by primary posterior sagittal anorectoplasty. Two cases with colostomy during the neonatal period were managed by laparoscopic assisted anorectoplasty at 6 months. None of the cases had a urinary leak during the postoperative period. All had a normal micturating cystourethrogram at 1 year. CONCLUSIONS: The approach of dividing fistula without ligation may prevent posterior urethral diverticula, but larger long-term follow-up studies are needed.

RESUMEN

AIM: Infantile haemangiomas are the most common tumor of infancy. We report the use of propranolol for treatment of problematic and complicated haemangiomas. PATIENTS AND METHODS: Propranolol was given to 52 children with mean age of 18.2 months at onset of treatment. After clinical and electrocardiographic evaluations, propranolol was administered with a starting dose of 2 mg/kg per day, given in 3 divided doses. Monthly follow up was done, response to oral propranolol therapy and any complications of therapy were recorded. Response to propranolol was classified as Complete Response, Excellent Response, Partial Response and Non Responder. RESULTS: Total 49 patients showed significant improvement after propranolol therapy out of which 4 patients were complete responder, 30 patients (56.7%) were excellent responders; 15 patients (28.8%) were partial responders. 3 patients (5.7%) had growth of haemangiomas despite propranolol therapy and were classified as non-responder. Side effect like hypotension, rashes, gastroesophageal reflux was reported by 3 patients. In our study mean duration of treatment was 6.5 months. At the end of treatment propranolol was stopped by with gradual tapering of dose over a period of 2 weeks. CONCLUSION: Propranolol administered orally at 2 mg/kg per day has rapid effective therapeutic effect in treatment of ulcerated haemangiomas and it appears to be a valuable and effective treatment option for infantile haemangiomas beyond the proliferative phase, and esthetically disfiguring haemangiomas.

RESUMEN

BACKGROUND/AIM: Mesenchymal hamartoma of liver (MHL) is a rare liver tumor of childhood. About 200 cases have been reported till now. Most of the work on MHL is limited to case reports and there are not many long term follow-up studies. We present our 20 years of experience with this uncommon entity. This study aims to highlight clinical features, diagnosis and treatment of MHL. MATERIALS AND METHODS: All patients with a diagnosis of MHL in last 20 years were included in this retrospective study. The patients were evaluated clinically, radiologically and pathologically. RESULTS: The total number of patients with a diagnosis of MHL was nine. Mean age of the patients was 19.89 ± 2.75 months. Right lobe was involved in eight patients. The prominent clinical features were distension of abdomen and anorexia. Surgical options used were hepatic lobectomy, wedge resection and enucleation. Histopathology of the specimens showed cysts of variable size with normal hepatocytes, bile ducts and connective tissue stroma. Overall mortality was one (11.11%). CONCLUSION: MHL is a benign tumor that can present with various clinical features. It should be differentiated carefully from other liver masses especially malignant ones. The diagnosis can be made with the help of radiology and histopathology. Adequate resection is curative in most of the cases and long-term follow up is satisfactory.

RESUMEN

Infantile hemangioma is a common disease. Steroids have been used for its treatment; however, intralesional steroids cause pain and other problems. A treatment modality that can avoid these problems is desirable. The authors evaluated the role of topical steroids as an alternative to intralesional steroids in the treatment of superficial hemangioma. Inclusion criteria were <2 superficial type ofhemangiomas <5 cm. The topical steroid mometasone furoate was applied twice daily. Intralesional triamcinolone acetonide was injected at monthly intervals using a 24-gauge needle at doses of 1 to 2 mg/kg. Forty-five (86.5%) patients responded to treatment with the topical steroids, of which 50% had excellent and 36.5% had good response. In the intralesional group, the response rate was 95.7%, of which 63.8% had excellent and 31.9% had good response. Complications in the topical steroid group were mild itching and irritation (19.2%) and hypopigmentation (7.6%). Complications in the intralesional group were pain (100%), bleeding (17%), infection (17%), cutaneous atrophy (8.5%), cushingoid facies (2.1%), and growth retardation (2.1%). Topical steroids are a reasonably good alternative to intralesional steroids as an initial choice for treating superficial hemangioma.

RESUMEN

Phenotypic presentation of 46,XY DSD depends on the underlying defects. Defect in androgen action on the target tissues or production of active metabolite share common morphological features. Molecular study may help differentiating these abnormalities with precision. Mutational analysis of androgen receptor (AR) and SRD5A2 genes was performed in 29 patients with 46,XY DSD, by PCR-SSCP. The amplicons that showed an aberrant migration in SSCP were subjected to sequencing. Interestingly, six patients from 4 unrelated families (a pair of sibs, uncle/nephew and other two isolated) were identified with mutations in SRD5A2 gene. In five patients p.R246Q missense mutation was detected, of which four were homozygous and one was compound heterozygous: g.80_87delT CGCGAAG (p.A27fsX132) and p.R246Q. Another patient with isolated micropenis harbored a heterozygous p.G196S missense mutation. No AR gene mutation was detected. In conclusion, our study suggests that p.R246Q mutation is common amongst patients with SRD5A2 gene defect from the Northern states of India. Also, it records a novel deletion in exon 1 of SRD5A2 gene in a patient with severe hypospadias.

RESUMEN

INTRODUCTION: Fetus in fetu is an extremely rare condition wherein a malformed fetus is found in the abdomen of its twin. This entity is differentiated from teratoma by its embryological origin, its unusual location in the retroperitoneal space, and the presence of vertebral organization with limb buds and well-developed organ systems. The literature cites less than 100 cases worldwide of twin fetus in fetu. CASE PRESENTATION: A two-and-a-half-month-old Asian Indian baby boy had two malformed fetuses in his abdomen. The pre-operative diagnosis was made by performing an ultrasound and a 64-slice computer tomography scan of the baby's abdomen. Two fetoid-like masses were successfully excised from the retroperitoneal area of his abdomen. A macroscopic examination, an X-ray of the specimen after operation, and the histological features observed were suggestive of twin fetus in fetu. CONCLUSION: Fetus in fetu is an extremely rare condition. Before any operation is carried out on a patient, imaging studies should first be conducted to differentiate this condition from teratoma. Surgical excision is a curative procedure, and a macroscopic examination of the sac should be done after twin or multiple fetus in fetu are excised.

RESUMEN

BACKGROUND: The management of an atrophic nonunion with a gap following a fracture of the radius and/or ulna is a challenging problem. Various methods of treatment available in the literature are cortical tibial graft (Boyd), ulnar segment graft (Miller and Phalen), iliac crest graft (Spira), cancellous insert graft (Nicoll), vascularized fibular graft (Jupiter), and bone transport by ring fixator (Tesworth). The present study reports the results of tricorticocancellous bone block grafts using modified Nicoll's technique, in diaphyseal defects of forearm bones. MATERIALS AND METHODS: A total of 38 forearm bones (either radius or ulna or both) in 23 patients with a gap of 1.5-7.5 cm were treated by debridement and tricorticocancellous bone block graft under compression with intramedullary nail fixation between June 1985 and June 2005. There were 15 male and 8 female patients. Sixteen patients had open and seven patients had closed fractures initially. Time of presentation since the original injury varied from 9 months to 84 months. Eighteen patients had already undergone one to three operations. RESULTS: Thirty-six bones showed union at both host graft junctions. The mean duration of union was 17.5 weeks (range, 14-60 weeks). Two bones had union only at one host graft junction and did not show any evidence of callus formation up to 9 months on the other end, hence requiring subsequent procedure in the form of phemister bone grafting. Patients were followed for a minimum period of 2 years (range, 2-7 years). Results were based on the status of union and range of motion (ROM) for elbow/wrist and grip strength at the final follow-up. Complications observed were the reactivation of infection (n = 1) and herniation of the muscles at the donor site (n = 1). CONCLUSION: The tricorticocancellous strut bone grafting under optimal compression, augmented with intramedullary fixation, provides a promising solution to difficult problem of an atrophic nonunion of forearms bones with gap.

RESUMEN

INTRODUCTION: The congenital constriction ring of lower extremity is very uncommon and rare condition. The actual incidence in general population is not known. In English literature, very few cases are reported time to time as congenital constriction band syndrome associated with musculoskeletal disorder like congenital talipes equino varus. The lesion can involve skin only or goes to deeper structure up to bone, which can lead to gangrene of foot or auto amputation. CASE PRESENTATION: We are presenting a case of bilateral congenital constriction ring in lower limb who presented at age of 4 year without any other associated congenital anomaly, simply managed by Z-plasty, which improves quality of life after physiotherapy. CONCLUSION: Congenital constriction ring of lower limb is extremely rare condition in children. Early diagnosis and management is mandatory, either in single stage or by stage procedure, to prevent auto-amputation of limb and to improve quality of life on feet.

RESUMEN

Importance of day-care surgery in pediatric age group is ever increasing and nowadays bulk of surgery is performed as a day-care procedure. Day-care procedure requires short intra-operative period and less postoperative complications. The introduction of tissue adhesive has been received enthusiastically since they may result in equivalent tensile strength-improved cosmetic appearance of the scar and lower infection rate when compared to sutures, staples and adhesive tape. We have used isoamyl 2-cyanoacrylate as a tissue adhesive for skin closure in day-care surgery. Novocryl is ideal for such procedure as it is a sterile, inert, non-toxic, biocompatible and bacteriostatic liquid topical skin adhesive containing isoamyl 2-cyanoacrylate formulation. We applied isoamyl 2-cyanoacrylate glue in 100 patients over skin cut margin after stitching subcutaneous tissue. Skin margin were held together by means of skin hook for 1-2 min. The cosmesis was better as there were no suture marks or lumpiness. There were no major complications in our study. Thus, isoamyl 2-cyanoacrylate can be considered as an alternative to skin suturing in the pediatric day-care surgery.

RESUMEN

BACKGROUND: Malunion due to progressive radial collapse during healing is a common complication following comminuted fracture distal radius treated by conventional methods. Many treatment modalities have been described with their own merits and demerits. Stabilization of ulnocarpal articulation is an effective method to prevent radial collapse during healing, and hence this study. MATERIALS AND METHODS: A prospective study of 200 patients of comminuted intraarticular fracture lower end radius between 20-75 years of age irrespective of sex, treated by closed reduction and percutaneous stabilization of ulnocarpal articulation and a well-molded above elbow POP cast for 6 weeks has been presented. Patients were evaluated at 1 year follow-up and functionally by Sarmiento's modification of Lindstrom criteria and Gartland and Werley's criteria. RESULTS: Excellent to good results were seen in 92%, fair in 6% and poor in 2% of the cases. Complications observed were, pintract infection (n = 6), malunion (n = 6), subluxation of the inferior radioulnar joint (n = 4) Sudeck's osteodystrophy (n = 3) and post-traumatic arthritis of the wrist (n = 3). CONCLUSION: Percutaneous fixation by this technique is an effective method to maintain the reduction, prevent radial collapse during healing, and to maintain the stability of the distal radioulnar joint even when the fracture is grossly comminuted, intraarticular, or unstable.

RESUMEN

BACKGROUND: A 21 day old male child presented with non bilious vomiting and abdominal mass. CASE PRESENTATION: This case is reported because pyloroduodenal duplication cysts are an extremely rare congenital anomaly, whose clinical presentation often mimics those of hypertrophic pyloric stenosis. Ultrasound examination showed cystic mass at pyloric region and barium study was suggestive of extrinsic mass compressing the pyloric region. A laparotomy, a tense cystic mass was present at the pyloroduodenal junction (PDC) which was resected and end to end anastomosis was done. Patients followed an uneventful recovery and doing well. CONCLUSION: The clinical and radiological analysis can reveal configurational changes consistent with a large extrinsic mass rather than muscular hypertrophy and can lead to accurate preoperative diagnosis.

RESUMEN

Mutation in the androgen receptor gene (AR) is known to cause androgen insensitivity syndrome (AIS). In an X-linked recessive manner, an AR mutation gets transmitted to the offspring through carrier mothers in 70% of cases, the other 30% arising de novo. However, reports on AR mutations amongst Indian patients with AIS are scarce in the literature. This study reports mutations in AR from two Indian families, each having a proband with partial androgen insensitivity syndrome (PAIS) phenotype. Clinical, endocrine and cytogenetic evaluation of these affected children was performed. Mutational analysis was carried out by polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) analysis followed by sequencing. The two point mutations were in exon 5: p.M742I, familial in patient 1 and p.V746M de novo in patient 2. These are hitherto unrecognized mutations in our population. Similar mutational studies are suggested in patients with AIS, in order to identify their frequency and clinical severity in our population.

RESUMEN

UNLABELLED: Urethrocutaneous fistula is one of the most common complications after hypospadias surgery. The incidence of fistula development has varied from 4% to 20% in larger series. We sought to investigate the role of fibrin glue (Tisseel manufactured by Baxter India Pvt Ltd, Chennai, India) to reduce the chances of fistula formation in cases in proximal penile hypospadias. METHOD: A total of 120 patients with proximal penile hypospadias (patients having urethral meatus at posterior third of penile shaft and at penoscrotal junction) were included in the present study. Patients were randomly allocated into 2 groups of 60 each by using Strata 9 software random number table. In group A, fibrin glue was used as a sealant after hypospadias surgery, whereas in group B, no sealant was used. All the operations were performed by single surgeon using transverse preputial tubularized island flap urethroplasty. RESULT: Fistula formation occurred in 6 cases in group A (10%) and 19 cases in group B (32%) (P = .027). The fistulae observed in fibrin glue group A were single and small in size (<1 mm). Multiple (>or=2 fistulae) and larger fistulae (>2 mm) were observed in group B. Overall complication was significantly higher in group B (P = .006). CONCLUSION: Fibrin glue in hypospadias repair does not eliminate fistula formation. However, it seems that it minimizes the incidence of fistula formation.

RESUMEN

BACKGROUND: Anorectal malformations are one of the most common congenital defects. This study is conducted to demonstrate new technique for treatment of rectovaginal fistula without disturbing the fourchette through posterior sagittal approach. METHOD: All the patients of rectovestibular fistula admitted after the neonatal age were treated with posterior sagittal anorectoplasty without opening the fourchette. The results were evaluated for cosmetic appearance and anal continence. RESULT: A total of 40 patients were included in our study. All patients were more than 1 month old. Operative time ranges from 70 to 150 minutes. The cosmetic appearance was good. Anal continence was good in 72% cases and fair in 20% cases. Fifteen percent of patients had minimal constipation and 7.5% patients had mucosal prolapse. CONCLUSION: Single-stage repair for vestibular anus through posterior sagittal anorectoplasty without opening fourchette has a good cosmetic appearance and good anal continence.

RESUMEN

OBJECTIVE: The aim of this study was to characterize a successful approach for the management of infants with long-gap esophageal atresia (EA) with tracheoesophageal fistula (TEF). The goal was to preserve the native esophagus and minimize the incidence of esophageal anastomotic leaks using fibrin glue as a sealant over the esophageal anastomosis. METHOD: A total of 52 patients were evaluated in this study. Only patients in whom, gap between the two ends of the esophagus was > or = 2 cm were selected during January 2005 to January 2007. Patients were divided in two groups on the basis of block randomization. Group A comprised the patients in whom fibrin sealant was used as reinforcement on a primary end-to-end esophageal anastomosis; in group B, fibrin glue was not used. The two groups were compared in terms of esophageal anastomotic leak (EL), postoperative esophageal stricture (ES), and mortality. The statistical analysis was done using Fisher's exact test and the chi-squared test. RESULT: The number of anastomotic leaks in group A (glue group) was about one-fifth that in group B (no glue group). The incidence of ES was almost twice as high in group B as in group A. The mortality rate was almost threefold higher in group B (no-glue group). The higher incidence of EL and ES in group B compared to group A was statistically significant. CONCLUSION: Thus, fibrin glue when used as an adjunct to esophageal anastomosis for primary repair of long-gap EA with TEF appears safe in the clinical setting and may lower the chances of esophageal leak and anastomosis-site strictures. Hence, it can diminish the mortality and morbidity of these patients.
