Neuroblastoma: essential genetic signaling pathways and current treatment options
2022, European Journal of Pharmacology
Blueberry muffin skin lesions, indicative of metastasis and stage IV-S neuroblastoma, appear as blue to purple nodules. The affected skin blanches with a surrounding erythematous rim due to friction and subsequent secretion of catecholamines (Shown and Durfee, 1970). In addition, several liver and bone marrow infiltrations are detected at this stage, which resolve without intervention.
Neuroblastoma is a highly diverse pediatric tumor originating in the neural crest and is responsible for more than 15% of all adolescent cancer deaths. Clinical signs and symptoms largely depend on the origin and spread of the tumor. Bone, lymph nodes, liver, intracranial and orbital tissues, lungs, and the central nervous system are commonly involved in metastatic neuroblastoma. Neuroblastoma enhances with contrast on computed tomography (CT) scans as a solid, heterogeneous mass that may involve adjacent ipsilateral or contralateral lymph nodes, tissues, and vessels. While magnetic resonance imaging (MR) achieves acceptable diagnostic accuracy for the detection of spinal cord and musculoskeletal metastases. Lorlatinib, a new ALK inhibitor designed to overcome this resistance, is currently being tested in the New Approaches to Neuroblastoma Therapy (NANT) consortium. Aurora kinase inhibitors have been reported to disrupt MYCN, which is particularly attractive given the lack of direct inhibitors targeting this driver in neuroblastoma. Sorafenib, an inhibitor of RAF kinase, and newer PI3K inhibitors are being tested in children with neuroblastoma to block RAS signaling. Despite various therapies, including chemotherapy, radiation therapy, immunotherapy and autologous stem cell transplantation in different risk groups for neuroblastoma, most patients undergo surgical removal of the tumor mass. The aim of this overview is to summarize current findings on neuroblastoma, its pathogenesis, its main genetic signaling pathways and the currently available therapy options for neuroblastoma.

Blueberry Muffin Baby and Spontaneous Remission of Neonatal Leukemia
2008, Archives of Pediatrics(Video) Neuroblastoma
IsBlueberry Muffin Babyis a rare skin syndrome observed in the neonatal period resulting in disseminated inflammatory papulonodules. Various causes should be sought, including congenital infections, hemolytic diseases of the newborn, and tumor pathologies. We present the case of a newborn who presented with this syndrome associated with an adrenal mass leading to the initial diagnosis of neuroblastoma. In fact, it was an adrenal localization of acute monoblastic leukemia with meningeal involvement. above allBlueberry Muffin Baby, it seems important to suggest leukemia even when no blasts are found on count and myelogram, as was the case in this patient. This observation is also special because of the occurrence of a spontaneous remission that persists after a year.
Blueberry Muffin Baby is a rare skin condition in newborn babies. Many causes are known, examples are congenital infections, hemolysis and tumors. We present a newborn with Blueberry Muffin Syndrome and an adrenal mass leading to the diagnosis of neuroblastoma. In reality, it was an acute monoblastic leukemia with adrenal localization and involvement of the liquor cerebrospinalis. Leukemia should always be suspected in such patients, even if white blood cell and bone marrow tests do not show blasts, as in this patient. This observation was also unusual because of the spontaneous remission. After one year of follow-up, the patient is in complete remission.

Purpura reflects the extravasation of red blood cells into the dermis. The appearance of purpura is an element of diagnostic orientation: petechial or ecchymotic purpura, infiltrated purpura, necrotic purpura. Thrombocytopenic purpura is common and manifests as petechial or ecchymotic purpura. Peripheral thrombocytopenia (normal myelogram) arises from infectious (viral or bacterial), drug, autoimmune, or idiopathic (idiopathic thrombocytopenic purpura) causes. They can be integrated into severe cases of disseminated intravascular coagulation (DIC) or purpura fulminans. Thrombocytopenic purpura of medullary origin due to insufficient production can have various causes, whether constitutional or acquired. Thrombopathic purpuras are less common. Vessel fragility can lead to ecchymotic purpura with minor trauma (Bateman's purpura of aging skin, scurvy, prolonged corticosteroid therapy). Necrotic purpuras, generally associated with inflammatory livedo and skin necrosis, should lead to a search for thrombotic pathologies (platelet-induced thrombosis, heparin intolerance, myeloproliferative syndromes, thrombophilic pathologies, thrombi of infectious origin) or embolism (fat embolism, crystal cholesterol, myxoma ). ). For infiltrating purpura, a skin biopsy should be done to look for vasculitis. Pigmented purpuras are individualized anatomoclinic units with benign but chronic development and undetermined etiology. Some dermatoses can have a purpuric component in their manifestation (urticaria, drug eruption, erysipelas, parapsoriasis). Finally, some paintings are individualized by their topography (papular purpura on gloves and socks) or by their context (Gardner and Diamond syndrome). Childhood forms include individualized entities: neonatal purpura fulminans (due to protein S or protein C deficiency), rheumatoid purpura, acute hemorrhagic edema in infants.
Purpura results from dermal extravasation of red blood cells. The presentation of the purpura is relevant for diagnostic orientation: petechial purpura, ecchymosis, infiltrated or necrotic purpura. Thrombocytopenia is a common cause of purpura and results in petechial purpura or ecchymosis. Thrombocytopenia with normal bone marrow analysis may be due to infection (viral or bacterial), drug, autoimmune disease, or be idiopathic (idiopathic thrombocytopenic purpura). Thrombocytopenia can be one of the elements of severe disseminated intravascular coagulation or purpura fulminans. The reduced production of platelets can be due to various congenital or acquired diseases of the bone marrow. Abnormal platelet functions are less common. Skin aging, vitamin C deficiency or prolonged corticosteroid therapy can trigger ecchymotic purpura due to the fragility of the vessel walls. Necrotic purpura, generally associated with inflammatory livedo and skin necrosis, may be due to microvascular thrombosis (platelet clots (heparin, myeloproliferative diseases with thrombocytosis), occlusion due to the growth of infectious agents in the vessels, changes in coagulation control (protein deficiency) C or S, antiphospholipids)) or embolization (fat embolization, cholesterol embolism, myxoma). With palpable (infiltrated) and inflammatory pupura, with leukocytoclastic vasculitis, skin biopsy is required. Chronic pigmented purpura represent a group of characteristic anatomoclinic entities with a chronic but benign development. The pathogenesis is unknown. Some dermatoses can be of purpuric origin (urticaria, drug reactions, erysipelas, lichenoid pityriasis). Some purples are distinguished by their topography (sock-and-glove syndrome) or by their context (Gardner-Diamond syndrome). Pediatric diseases include neonatal purpura fulminans (protein S or C deficiency), Henoch-Schönlein purpura and acute hemorrhagic edema in infancy.

Outcomes of chest wall resections in patients with pediatric sarcoma
Journal of Pediatric Surgery, Band 52, Nummer 1, 2017, S. 109-114
Chest wall tumors in pediatric patients are rare. This study evaluates outcomes in pediatric patients undergoing chest wall resection secondary to sarcoma.(Video) stages of neuroblastoma part 7.
A retrospective review of patients less than 19 years of age who underwent chest wall resection for sarcoma at the University of Texas MD Anderson Cancer Center between 1999 and 2014 was performed.
Of 44 patients, Ewing's sarcoma (n=18) and osteosarcoma (n=16) were the most common. Other sarcomas were synovial sarcoma, chondrosarcoma and rhabdomyosarcoma. Gore-Tex® or Marlex™ mesh and methyl methacrylate sandwich were used in 22 patients and no reconstruction was required in 9 children. Twenty-four (54.5%) patients were normally active, 3 (6.8%) had occasional discomfort, 2 (4.5%) had pain that interfered with function, 7 (15.9%) required medication for the disorder or physical therapy. and 8 (18.2%). %) required an additional operation. Five children (11.4%) developed scoliosis and all of these patients had posterior rib tumors. The median overall survival for the entire cohort was 41.9 ± 11.82 months. Histology (p=0.003), tumor location in the ribs (p=0.007), and surgical margins (p=0.011) were significantly associated with overall survival. Tumors in the middle and posterior part of the ribs (p=0.003) had a lower probability of death.
Scoliosis is more common in posterior rib resections. Histology, tumor location, and surgical margins affect survival but not the type of reconstruction.

Solitary xanthogranuloma (juvenile): A comprehensive immunohistochemical study focusing on newly developed markers of the histiocytic lineage
Human Pathology, Band 46, Nummer 9, 2015, S. 1390-1397
Solitary (juvenile) xanthogranuloma (SXG) is a rare benign lesion that usually occurs in children. The cell of origin of SXG has been the subject of debate, with hypotheses such as endothelium, dermal dendrocytes, undetermined dermal cells, and plasmacytoid monocytes, among others. In addition, we characterized the SXG immunophenotype using an extended immunohistochemical panel, paying particular attention to new or recently described markers of histiocytic lineage. Forty-one SXG and 23 benign fibrous histiocytomas (BFH) were immunostained for factor XIIIa, CD4, CD11c, CD163, CD31, CD45, lysozyme and S-100. Mononuclear SXG cells and BFH spindle cells were scored as “negative”, “1+” (<10% positive), “2+” (10–50% positive), and “3+” (>50% positive). % positive). SXG immunohistochemistry showed the following: Factor XIIIa, 35/40 (88%); CD4, 34/36 (94%); CD11c, 36/37 (97%); CD163, 36/36 (100%); CD31, 14/31 (45%); CD45, 14/32 (44%); lysozyme, 23/30 (77%); and S-100, 0/32 (0%). The 5 cases with negative factor XIIIa showed expression of 2+-3+ CD4, CD11c and CD163. In contrast, only 8 (35%) of the 23 BFH cases were positive for factor XIIIa. All other staining was consistently negative in BFH lesion cells, although these tumors often contained intercalated cells expressing various histiocytic markers. Our results strongly support the histiocytic lineage of mononuclear SXG cells. CD11c expression has not previously been described in SXG. The expression of CD163 appears to be characteristic of SXG since, contrary to previous reports, it was not expressed by the BFH lesion cells. The expression of CD31 on SXG represents a potential diagnostic problem, since many (dermato-)pathologists are not aware of CD31 expression on histiocytes.

Functional sequences in human crystalline alphaB
Biochimica et Biophysica Acta (BBA) – General Topics, Volume 1860, Number 1, Part B, 2016, pp. 240-2
Human crystalline alphaB (HspB5) contains the core alphacrystalline domain, a series of antiparallel beta strands arranged in the characteristic beta sandwich of small heat shock proteins (sHsps). The full three-dimensional structure of the alpha-crystal has not been determined and the mechanism of biological activity remains uncertain as sHsp are involved in multiple interactions with a variety of target proteins that promote self-assembly of fibrils and polydisperse complexes. We chose human crystalline alphaB to study interactive sequences because it is involved in many human condensation, amyloid, and aggregation diseases and is very sensitive to destabilization of unfolding proteins. Sophisticated methods are used to analyze and complete the structure of alphaB-crystallin with the expectation of understanding sHsp function. This Review addresses the identification of interactive sites on the alphaB lens surface, which may be key to understanding the multifunctional activity of the human alphaB lens.
This Review summarizes research to identify bioactive interactive sequences responsible for the function of human alphaB-crystallin, an sHsp with chaperone-like activity.
The multifunctional activity of human crystalline alphaB results from the interacting peptide sequences exposed on the surface of the molecule. The multiple noncovalently interacting sequences could explain the selectivity and sensitivity of crystalline alphaB at the onset of protein unfolding.
Human crystalline alphaB may be an important part of an endogenous protective mechanism in senescent cells and tissues. This article is part of a special issue entitled Crystal Biochemistry in Health and Disease.
Early-onset primary adrenal insufficiency in men with adrenoleukodystrophy: case series and review of the literature
Das Journal of Pediatrics, Bd. 211-2
The lifetime risk of adrenal insufficiency in male children with adrenoleukodystrophy (ALD) is estimated at 80-86%. Prior to newborn screening, male infants with ALD were identified based on family history or the onset of symptoms. These young patients with ALD and adrenal insufficiency support newborn ALD screening.(Video) Pediatric Renal Tumors Usual and Unusual

It is not common. The term was coined in the 1960s to describe the skin changes in babies with congenital rubella.Is a blueberry muffin baby CMV or rubella? ›
Blueberry muffin baby is a term used to describe a purplish or bluish-red maculopapular rash present at birth, typically on the face, neck, and trunk. Traditionally, it has been used to describe the cutaneous findings of congenital rubella, but other conditions can produce the same skin findings.What are Harlequin spots newborn? ›
Usually occurring between two and five days of age, harlequin colour change has been seen as late as three weeks of age. The condition is benign, and the change of colour fades away in 30 seconds to 20 minutes. It may recur when the infant is placed on her or his side.What is the differential diagnosis of blueberry muffin? ›
The term blueberry muffin baby was initially coined by pediatricians to describe cutaneous manifestations observed in newborns infected with rubella during the American epidemic of the 1960s. These children had generalized hemorrhagic purpuric eruptions that on histopathology showed dermal erythropoiesis.
Although rare, some children may have a sensitivity to certain compounds found in blueberries called salicylates, which have been known to cause allergy-like symptoms like hives and nasal congestion in some people.
Infants under 12 months of age that eat foods high in nitrate or drink water with nitrate in it are more likely to have methemoglobinemia. Methemoglobinemia can be also caused by certain medications (e.g., benzocaine, dapsone) and chemicals (e.g., aniline, naphthalene).What happens when a baby is born with CMV? ›
CMV is the most common infectious cause of birth defects in the United States. About 1 out of 200 babies is born with congenital CMV. One out of 5 babies with congenital CMV will have symptoms or long-term health problems, such as hearing loss. In the most severe cases, CMV can cause pregnancy loss.What does CMV do to a baby? ›
Babies born with CMV can have brain, liver, spleen, lung, and growth problems. The most common long-term health problem in babies born with congenital CMV infection is hearing loss, which may be detected soon after birth or may develop later in childhood.What does CMV do to the body? ›
CMV is related to the herpes virus that causes cold sores and chickenpox. Once you have the virus, it stays in your body for the rest of your life. Your immune system usually controls the virus and most people do not realise they have it.How long can a child live with neuroblastoma? ›
Neuroblastoma survival rates vary depending on risk group. Children in low and intermediate risk groups survive at least 5 years over 90% of the time. High risk children survive 5 years about half the time. It's likely that survival rates will continue to improve over time as treatment improves.How aggressive is neuroblastoma? ›
Infants usually develop a form of neuroblastoma that is less aggressive and can mature into a benign tumor. Children over 12 – 18 months usually develop a more aggressive form of neuroblastoma that often invades vital structures and may spread throughout the body.What is the prognosis for neuroblastoma in infants? ›
Outlook / Prognosis
Younger children with low- or intermediate-risk neuroblastoma have a good prognosis and a 90% to 95% survival rate. Older kids and those with high-risk neuroblastoma live cancer-free around 60% of the time.
The 10-year overall survival increased in patients with stage 1–3 neuroblastoma from 83 to 91%, for stage 4S from 80 to 85%, and for stage 4 aged ≥18 months from 2 to 38%.What is the prognosis for metastatic neuroblastoma? ›
The 5-year survival rate of low- and medium-risk children has been estimated to reach 75–98% but that of high-risk children is less than 50% [2, 3]. Relapse or progression at the metastatic site is a major cause of NB-related mortality .
Conclusions: More than 50% of children with stage 4 NB may survive.What does blueberry muffin do? ›
Blueberry Muffin, aka Blueberry Muffins, is an indica-dominant strain produced by Humboldt Seed Company. It is an 80% indica, 20% sativa cross of Razzleberry and Purple Panty Dropper and is often described as having relaxing, arousing, and energizing effects.Can CMV be transmitted through breast milk? ›
CMV can be transmitted to infants through contact with the mother's genital secretions during delivery or through breast milk. Healthy infants and children who acquire CMV after birth generally have few, if any, symptoms or complications from the infection.What is the difference between CMV and congenital CMV? ›
While most people infected with CMV have no symptoms (and don't need any treatment), babies born with congenital CMV can have problems related to breathing, hearing, and seeing, as well as mental disabilities.Where does CMV come from? ›
CMV is found in bodily fluids such as saliva, urine, semen, and others. The virus is easily spread in households and in daycare centers. It can be transmitted to the fetus during pregnancy and to the baby during delivery or in breast milk.What is bronze baby syndrome? ›
"Bronze baby" syndrome is a rare complication of phototherapy for neonatal jaundice occurring due to modified liver function, particularly cholestasis, of various origins. We report a case which occurred in a premature infant who developed a grey-brown coloration during phototherapy.Can a harlequin baby survive? ›

Blueberries may be introduced as soon as baby is ready to start solids, which is generally around 6 months of age.Do blueberries help baby brain development? ›
Blueberries for babies are a rich source of antioxidants and natural sugars. Along with helping regulate your baby's blood pressure, these berries can also help in the cognitive development of babies and make their bones strong. You can start including blueberries in your baby's diet when they begin to have solid food.What are the health disadvantages of blueberry? ›
Excessive consumption of blueberries can lead to digestive issues, blood sugar imbalances, tooth decay, allergic reactions, and kidney stones. If you're unsure about how many blueberries to consume, it's always a good idea to consult with a healthcare professional.What are the long term effects of being a blue baby? ›
Cerebral palsy, epilepsy, and nerve damage can impact a child's ability to move independently. They might also suffer muscle spasms throughout their lifetime.What are two symptoms of blue baby syndrome? ›
Blue baby syndrome, also known as cyanosis, is when your baby's skin has a bluish discoloration, especially when they cry. The discoloration is most obvious in your baby's lips and hands. This condition is caused when there is a shortage of oxygen in your baby's blood.Do blue babies survive? ›
While cyanosis in the newborn can be an alarming symptom, the majority of these children are able to survive in their early life. Further, many of them are subjected to stressful, staged procedures to repair or palliate their underlying issue – only underscoring the adaptive capabilities of our smallest patients.Can kissing babies cause CMV? ›
Treatment for CMV in pregnancy
It is important for all pregnant women to follow simple hygiene precautions to reduce their risk of infection: Avoid sharing dummies, cutlery, drinks or food with anyone. Avoid kissing babies, toddlers and small children directly on the mouth.
At birth, 90% of babies born with congenital CMV will present as asymptomatic, showing no obvious and visible symptoms of the virus. These children are expected to live healthy lives, typically following standard growth and development patterns.What virus causes small heads in newborns? ›
Zika and Microcephaly
Microcephaly is a birth defect in which a baby's head is smaller than expected when compared to babies of the same sex and age. Babies with microcephaly often have smaller brains that might not have developed properly. Zika virus infection during pregnancy is a cause of microcephaly.
Most babies with congenital CMV don't have health problems, but about 1 in 5 babies with congenital CMV can get sick from the virus or have long-term health problems. Some babies born with CMV have signs and symptoms, including: Hearing loss.
If a pregnant woman is infected with CMV, she can pass it to her developing baby. This is called congenital CMV, and it can cause birth defects and other health problems.What kills CMV virus? ›
Antiviral medications are the most common type of treatment. They can slow reproduction of the virus, but can't eliminate it. Researchers are studying new medications and vaccines to treat and prevent CMV .What does CMV do to the brain? ›
Congenital cytomegalovirus (CMV) infection is a significant cause of brain disorders, such as microcephaly, mental retardation, hearing loss and visual disorders in humans. The type and severity of brain disorder may be dependent on the stage of embryonic development when the congenital infection occurs.What are the long term effects of congenital CMV? ›
About 40 to 60% of infants born with signs of congenital CMV disease at birth will have long-term health problems, such as: Hearing loss. Vision loss. Intellectual disability.What organ does cytomegalovirus affect? ›
CMV can infect virtually any organ of the human body. The most common organs include the blood, brain, colon, eye, heart, kidney, liver, lung and stomach. In the case of an organ transplant patient, the symptoms of CMV can be easily confused with rejection.What does a neuroblastoma lump look like? ›
blueish lumps in the skin and bruising, particularly around the eyes. weakness in the legs and an unsteady walk, with numbness in the lower body, constipation and difficulty peeing. fatigue, loss of energy, pale skin, loss of appetite and weight loss.What is the hallmark of neuroblastoma? ›
A hallmark of neuroblastoma is cellular heterogeneity. Although the presence of phenotypically diverse cells could be explained by ongoing mu- tagenesis, the cancer stem cell hypothesis has provided an intriguing alterna- tive explanation for neuroblastoma heterogeneity.Where is the tumor most commonly found in neuroblastoma? ›
Neuroblastoma most commonly arises in and around the adrenal glands, which have similar origins to nerve cells and sit atop the kidneys. However, neuroblastoma can also develop in other areas of the abdomen and in the chest, neck and near the spine, where groups of nerve cells exist.How common is neuroblastoma in infants? ›
The average age of a child diagnosed with neuroblastoma is about 18 months of age but the condition is occasionally seen in teenagers or even young adults. It is found slightly more often in boys than in girls. In the United States, about 800 new cases of neuroblastoma are diagnosed each year.How are babies born with neuroblastoma? ›
Neuroblastoma develops from nerve cells in the fetus called neuroblasts. Usually, as a fetus matures and after birth, the neuroblasts develop normally. Sometimes they become cancerous, causing neuroblastoma. Neuroblastoma can be inherited (passed down in families).
Stage 4: the tumor has spread to distant parts of the body such as lymph nodes, bone, bone marrow, skin, liver, and/or other organs. Stage 4S: only applicable in children under 1 year of age. The cancer has potentially spread to lymph nodes, liver, skin, and/or bone marrow but only on one side of the body.Can a child survive stage 4 neuroblastoma? ›
70% of cases at diagnosis have already spread to other areas of the body which places the cancer in a Stage 4 category. The 5-year survival rate for high-risk Neuroblastoma is 50%. 60% of patients with high-risk Neuroblastoma will relapse. Once in relapse, the survival rate drops to less than 5%.What is the root cause of neuroblastoma? ›
Most neuroblastomas are the result of gene changes in neuroblasts that happen during the child's development, sometimes even before birth. What causes these acquired gene changes is not known. They might be just be random events that sometimes happen inside cells, without having an outside cause.What is metastatic neuroblastoma? ›
The metastatic tumor is the same type of cancer as the primary tumor. For example, if neuroblastoma spreads to the liver, the cancer cells in the liver are actually neuroblastoma cells. The disease is metastatic neuroblastoma, not liver cancer.What is high risk neuroblastoma with metastasis? ›
Patients with high-risk neuroblastoma (HR-NB) are frequently diagnosed with stage 4 disease with widespread metastasis most commonly in bone marrow, bone, lymph nodes and liver. Modern clinical management for HR-NB includes multimodal chemotherapy, surgical resection, radiotherapy and immunotherapy.Which AML has worst prognosis? ›
Secondary AML has a worse prognosis, as does treatment-related AML arising after chemotherapy for another previous malignancy. Both of these entities are associated with a high rate of unfavorable genetic mutations.What is the rarest AML? ›
Acute promyelocytic leukemia (APL) is a rare subtype of AML. It's associated with a specific genetic change called the PML/RARA fusion gene. In APL, immature WBCs called promyelocytes begin to gather in the blood and bone marrow.
