Men who grew up in challenging conditions like prevalence of infectious diseases or poor nutrition may have lower levels of testosterone — male sex hormone — in later life, says a study.

The findings suggest that the differences may be linked to energy investment. For instance, in environments where people are more exposed to disease or poor nutrition, developing males direct their energy towards survival at the cost of testosterone.

While high testosterone levels may up the risk of ageing, muscle mass, prostate enlargement and cancer, lower levels may cause lack of energy, erectile dysfunction etc. Thus, the researchers suggest that any screening for risk profiles may need to take a man’s childhood environment into account.

“Very high and very low testosterone levels can have implications for men’s health and it could be important to know more about men’s childhood circumstances to build a fuller picture of their risk factors for certain conditions or diseases,” said Gillian Bentley from Britain’s Durham University.

For the study, published in the journal Nature Ecology and Evolution, the team collected data from 359 men born and still resident in Bangladesh; Bangladeshi men who moved to London as children; Bangladeshi men who moved to London as adults; second-generation, Britain born men whose parents were Bangladeshi migrants; and Britain born ethnic Europeans.

The results showed that Bangladeshi men who grew up and lived as adults in Britain had significantly higher levels of testosterone compared to relatively well-off men who grew up and lived in Bangladesh as adults.

Bangladeshis in Britain also reached puberty at a younger age and were taller than men who lived in Bangladesh throughout their childhood.

Further, it was also found that the aspects of male reproductive function remain changeable up to the age of 19 and are more flexible in early rather than late childhood, but no longer heavily influenced by their surroundings. (IANS)

Cancer remains one of the leading causes of death from disease in childhood. Each year, many children between birth and the age of 18 are diagnosed with cancer.

The signs and symptoms of cancer in children could be very nonspecific leading to delayed diagnosis. There are certain red flags that can increase the index of suspicion and can help in making the diagnosis sooner than later.

Dr Vikas Dua, Additional Director & HOD, Pediatric Hematology Oncology and Bone Marrow Transplant, Fortis Memorial Research Institute, Gurugram discusses about the top four childhood cancers and the signs and symptoms associated with them.

Acute Leukemia

Leukemia is the most common cancers observed in children. It commonly occurs in children between the ages of 2-4 years. Leukemia is a cancer of the bone marrow. Three out of four childhood leukemia cases are Acute Lymphoblastic Leukemia (ALL). The rest are Acute Myeloid Leukemia (AML).

Symptoms of leukemia

Bone and joint pain
Fatigue
Weakness
Bleeding
Prolonged Fever
Weight loss

Brain Tumors

Brain tumors and other nervous system tumors are the second most common cancer seen in pediatric age group. Brain tumors are of many types and the outlook and treatment for each varies. In regard with brain tumors in children, it starts in the lower parts of the brain, such as the cerebellum or brain stem. Although brain tumors in children is typically different from that of brain tumors of adults, many of the symptoms remain the same.

Symptoms of brain tumors

Headaches (often with early morning vomiting) e Dizziness e Balance problems e Vision, hearing or speech problems
Frequent vomiting

Neuroblastoma

Neuroblastoma arises from immature nerve cells in infants and young children. Mainly found in children younger than age of 5 years, this disease often begins in the adrenal glands.

Symptoms of neuroblastoma

Impaired ability to walk
Change in eyes (droopy eyelids, bulging,)
Pain in different and various locations of the body
High blood pressure Lymphoma starts in certain cells of the immune system called lymphocytes.

This cancer affects lymph nodes and other lymph tissues, like the tonsils or thymus. These can also affect bone marrow as well as organs and can cause varied symptoms depending on where the cancer is growing.

Hodgkin lymphoma

Sometimes called Hodgkin disease, is rare in children younger than 5 years of age. This type of cancer is similar in both children and adults, including the types of treatment that works best.

Non-Hodgkin lymphoma

More likely to occur in younger children than Hodgkin lymphoma, but still rare in children younger than age group of 3. The most common types of non-Hodgkin lymphoma vary in children and adults. Often these cancers grow quickly which requires severe treatment, but they also tend to respond better to treatment than most non-Hodgkin lymphomas in adults.
