RESUMO

Germ cell tumors (GCTs) are associated with pure gonadal dysgenesis or Swyer syndrome. Swyer syndrome usually presents with primary amenorrhea, streak ovaries, and mixed GCT. However, our patient presented with secondary amenorrhea, normal female external genitalia, and a mixed GCT. Constitutional karyotype was suggestive of 46,XY. Management comprised chemotherapy, followed by surgery. Histopathology was suggestive of dysgerminoma complicating a gonadoblastoma. The purpose of reporting this case is its rarity and the importance of diagnosing an XY karyotype, as the incidence of GCTs is higher in these patients.

RESUMO

JUSTIFICATION: In India, there is a lack of uniformity of treatment strategies for aplastic anemia (AA), and many children are managed only with supportive care due to non-availability of hematopoietic stem cell transplantation (HSCT). PROCESS: Eminent national faculty members were invited to participate in the process of forming a consensus statement in Hyderabad in July, 2016. Draft guidelines were circulated to all members, and comments received in a online meeting in October, 2020 were incorporated into the final draft. These were approved by all experts. Objective: To facilitate appropriate management of children with acquired aplastic anemia. RECOMMENDATIONS: Key recommendations are: i) A bone marrow biopsy is must to make a diagnosis of AA; ii) Rule out inherited bone marrow failure syndromes (IBMFS), connective tissue disorders, viral infections, paroxysmal nocturnal hemoglobinuria (PNH), drug or heavy metal induced marrow suppression in all cases of AA; iii) Conservative approach to transfusions should be followed, with a target to keep hemoglobin >6 g/dL in children with no co-morbidities; iv) HLA-matched sibling donor HSCT is the preferred choice of treatment for newly diagnosed very severe/ severe AA; v) In absence of HLA-matched family donor, a matched unrelated donor (MUD) transplant or immunosuppressive therapy (IST) should be considered as alternate choice based on physician expertise; vi) Fludarabine, cyclophos-phamide and anti-thymocyte globulin (ATG) based conditioning with cyclosporine and methotrexate as graft versus host disease (GvHD) prophylaxis is the preferred regimen; vii) Horse ATG and cyclosporine are the recommended drugs for IST. One should wait for 3-6 months for the response assessment and consideration of next line therapy.

RESUMO

The diagnosis of blood-borne infections in immunocompromised patients is a major challenge for the clinical microbiology laboratory. Isolation of bloodborne pathogens in these patients has profound clinical implications, yet is fraught with technical problems, including the presence of unusual and difficult to isolate pathogens. Coupled with this is the problem of false-positive blood culture signals from automated blood culture systems which further delays the definitive diagnosis. Here, we present a case of an 8-year-old boy with Ph +ve acute lymphoblastic leukaemia who has repeated 'false positive' blood cultures and later grew an uncommon organism.

RESUMO

Brevibacteria are a part of the normal skin flora and may be dismissed in blood cultures as contaminants. They have been reported as opportunistic pathogens in immunocompromised patients. We report a catheter-related bloodstream infection with Brevibacterium casei in a 6-year-old child with aplastic anaemia. Treatment with appropriate antibiotics along with the removal of the catheter resulted in complete cure in our patient.

RESUMO

JUSTIFICATION: Practitioners and people need information about the therapeutic potential of umbilical cord blood stem cells and pros and cons of storing cord blood in public versus private banks. PROCESS: Indian Academy of Pediatrics conducted a consultative meeting on umbilical cord blood banking on 25th June 2016 in Pune, attended by experts in the field of hematopoietic stem cell transplantation working across India. Review of scientific literature was also performed. All expert committee members reviewed the final manuscript. OBJECTIVE: To bring out consensus guidelines for umbilical cord banking in India. RECOMMENDATIONS: Umbilical cord blood stem cell transplantation has been used to cure many malignant disorders, hematological conditions, immune deficiency disorders and inherited metabolic disorders, even when it's partially HLA mismatched. Collection procedure is safe for mother and baby in an otherwise uncomplicated delivery. Public cord blood banking should be promoted over private banking. Private cord blood banking is highly recommended when an existing family member (sibling or biological parent) is suffering from diseases approved to be cured by allogenic stem cell transplantation. Otherwise, private cord blood banking is not a 'biological insurance', and should be discouraged. At present, autologous cord stem cells cannot be used for treating diseases of genetic origin, metabolic disorders and hematological cancers. Advertisements for private banking are often misleading. Legislative measures are required to regularize the marketing strategies of cord blood banking.

RESUMO

Skin involvement in Burkitt's lymphoma (BL) is rare, more so in the pediatric age group. There are very few cases of BL involving skin either at presentation or relapse reported in literature. We report a case of a 9-years old boy with stage 4 Burkitt's lymphoma with skin involvement who tested negative for human immune-deficiency virus.

RESUMO

Haematogones are benign B lymphoid precursors which may mimic neoplastic lymphoblasts and pose diagnostic difficulty especially when the percentage of haematogones exceeds 10% in the bone marrow. Flow cytometric analysis with combination of CD19/CD10/CD20/CD34/CD38/CD58 can be used to differentiate the two depending upon the difference in the fluorescence intensity between blasts and haematogones. We hereby present a case of Common Acute Lymphoblastic Leukaemia Associated Antigen (CALLA) positive Acute Lymphoblastic Leukaemia (ALL), in which patient presented with haematogone proliferation in bone marrow after 6 months of chemotherapy mimicking relapse. The distinction was made on flow cytometric immunophenotyping by using optimal antibody combination. Distinction of benign haematogones from neoplastic lymphoblasts is essential for disease management in cases of post chemotherapy or post marrow transplant, especially in patients of ALL. Flow cytometric immunophenotyping is reliable to distinguish haematogones from residual lymphoblasts in almost all cases when optimal antibody combinations are used.

RESUMO

BACKGROUND: Hematopoietic progenitor stem cell transplantation (HPSCT) is used as a standard treatment option to improve outcome in hematological and nonhematological disorders. It is important for new HPSCT program to look at its patient outcome data and compare it with the published data to evaluate the efficacy of program. AIMS: The aim was to compile and collate the patient outcome data of HPSCT and compare with published reports. MATERIALS AND METHODS: Patient demographics, indications, stem cell harvest by apheresis, dose collected, infusion, engraftment, and follow-up data were collected from hospital information system from 2010 to 2013 in a tertiary care hospital. HPSCs were mobilized with granulocyte colony-stimulating factor, and harvests were done on the 5(th) day. Engraftment was decided for neutrophil when counts were 0.5 × 10(9)/L and for platelets when counts were 20 × 10(9)/L on two consecutive days without any transfusion support. RESULTS: There were 133 harvests for 95 patients with various disorders; multiple myeloma was most common in autologous and acute lymphoblastic leukemia in allogeneic group. One hundred harvests were done for autologous and 33 for allogeneic HPSCT. In autologous group, of 66 patients, 60 (90.9%) received stem cell infusion at median dose of 4.63 × 10(6) CD34(+) cells/kg. Similarly, in allogeneic group, of 29 patients, 27 (93.10%) received infusion at median dose of 5.8 × 10(6) CD34(+) cells/kg. 58 (96.9%) patients and 25 (92.6%) engrafted in autologous and allogeneic group, respectively. The median time for neutrophils engraftment was 11 days in autologous group and 12 days in allogeneic group. The median time for platelet engraftment was 11.5 days in autologous group and 13 days in allogeneic group. The 100-day survival rate was 95% (n = 57) in autologous group and 77.8% (n = 21) in allogeneic group. CONCLUSION: This data analysis shows reasonably good results of HPSCTs with majority of patients surviving at 100-day follow-up.

RESUMO

CONTEXT: Steady improvement in childhood cancer outcomes has led to a growing number of survivors, many of who develop long-term sequelae. There is limited data about these sequelae (including those related to fertility) on childhood cancer survivors from India. AIMS: We undertook a prospective pilot study on childhood cancer survivors from India to assess their gonadal function and fertility. SUBJECTS AND METHODS: A pediatric oncologist and a reproductive medicine specialist assessed 21 childhood cancer survivors. The risk of infertility was established using disease and treatment variables. Current status of puberty, sexuality, and fertility were assessed using clinical and biochemical parameters. Outcomes were correlated with risk group of infertility. Information was also ascertained on counseling with regards to risk of infertility. RESULTS: The cohort included 21 survivors (71% males) with a median age of 18 years who were off treatment for a median age of 7 years. Ten (48%) survivors were at low risk for infertility, 9 (43%) at medium risk and 2 (9%) at high risk. Gonadal dysfunction was seen in 3 (14%) survivors: 0/10 (0%) low risk, 1/9 (11%) medium risk, and 2/2 (100%) high risk. None of the survivors, who are at high risk or medium risk of infertility, received any counseling before treatment. CONCLUSIONS: This prospective pilot study of a cohort of childhood cancer survivors from India demonstrates a deficiency in the information provided and counseling of patients/families at the time of diagnosis with regards to the risk of infertility. Fertility outcomes of childhood cancer survivors were congruent with recognized risk groups for infertility. Future action points have been identified.

RESUMO

Five years five month old male child diagnosed with aplastic anemia required blood and platelet support regularly. He was advised bone marrow transplant (BMT) and had 6/6 match with a younger sibling (11 months old). He was admitted for planned BMT and was put on preparatory regimen five days prior to BMT. GCSF-primed bone marrow (BM) harvest was done from the donor, but the harvest was insufficient (1.05 × 10^6 /kg) and target dose of 4 million stem cells per kg could not be achieved. The BM harvest was infused into the patient and a repeat BM harvest was contemplated on next day. After careful evaluation of risks and benefits to the patient and the young donor, a decision to do a peripheral blood stem cell (PBSC) harvest was taken. The apheresis kit was blood primed to preclude possible hemodynamic imbalance in the donor considering low weight and young age. The entire harvest procedure (321 minutes) was uneventful with the donor remaining stable throughout. A dose of 2.40 million per kg of CD34+ cells was harvested and infused. Thus, a total dose of 3.45 million (1.05 BM and 2.4 PBSC) per kg was infused into the patient. Neutrophil and platelet engraftments and donor chimerism were achieved successfully with tandem BM-PBSC infusion and the patient continues to be disease free till 180 days follow up. This is possibly first published Indian report on BM-PBSC tandem transplant suggesting safety of PBSC harvests in small-weight young-age donor.

RESUMO

Anaplastic lymphoma kinase (ALK) positive Anaplastic large cell lymphoma (ALCL) represents approximately 2% of all Non-Hodgkin's lymphomas that commonly involves nodal as well as a wide variety of extra nodal sites, as skin, soft tissue, bones and lungs, although primary or secondary involvement of bone is rare. Herein, we report a case of 14-year-old female child presented as extensive bony involvement with a clinical diagnosis of bone tumour/ small round cell tumour, which was proved to be ALK positive ALCL on histopathological examination.

RESUMO

The survival of children with cancer in India is inferior to that of children in high-income countries. The Indian Pediatric Hematology Oncology Group (IPHOG) held a series of online meetings via www.Cure4kids.org to identify barriers to cure and develop strategies to improve outcomes. Five major hurdles were identified: delayed diagnosis, abandonment, sepsis, lack of co-operative groups, and relapse. Development of regional networks like IPHOG has allowed rapid identification of local causes of treatment failure for children with cancer in India and identification of strategies likely to improve care and outcomes in the participating centers. Next steps will include interventions to raise community awareness of childhood cancer, promote early diagnosis and referral, and reduce abandonment and toxic death at each center. Starting of fellowship programs in pediatric hemato-oncology, short training programs for pediatricians, publishing outcome data, formation of parent and patient support groups, choosing the right and effective treatment protocol, and setting up of bone marrow transplant services are some of the effective steps taken in the last decade, which needs to be supported further.
