Dependent personality disorder (DPD) is characterized by a pervasive psychological dependence on other people. This personality disorder is a long-term condition in which people depend on others to meet their emotional and physical needs, with only a minority achieving normal levels of independence. Dependent personality disorder is a cluster C personality disorder, which is characterized by excessive fear and anxiety. It begins prior to early adulthood, and it is present in a variety of contexts and is associated with inadequate functioning. Symptoms can include anything from extreme passivity, devastation or helplessness when relationships end, avoidance of responsibilities and severe submission. Signs and symptoms
People who have dependent personality disorder are overdependent on other people when it comes to making decisions. They cannot make a decision on their own as they need constant approval from other people. Consequently, individuals diagnosed with DPD tend to place needs and opinions of others above their own as they do not have the confidence to trust their decisions. This kind of behaviour can explain why people with DPD tend to show passive and clingy behaviour. These individuals display a fear of separation and cannot stand being alone. When alone, they experience feelings of isolation and loneliness due to their overwhelming dependence on other people. Generally people with DPD are also pessimistic: they expect the worst out of situations or believe that the worst will happen. They tend to be more introverted and are more sensitive to criticism and fear rejection.
In hypophosphatemic rickets, calcium levels may be within or slightly below the reference range; alkaline phosphatase levels will be significantly above the reference range.Carefully evaluate serum phosphate levels in the first year of life, because the concentration reference range for infants (5.0–7.5 mg/dL) is high compared with that for adults (2.7–4.5 mg/dL).Serum parathyroid hormone levels are within the reference range or slightly elevated, while calcitriol levels are low or within the lower reference range. Most importantly, urinary loss of phosphate is above the reference range.The renal tubular reabsorption of phosphate (TRP) in X-linked hypophosphatemia is 60%; normal TRP exceeds 90% at the same reduced plasma phosphate concentration. The TRP is calculated with the following formula:1 - [Phosphate Clearance (CPi) / Creatinine Clearance (Ccr)] X 100

Treatment
Oral phosphate, calcitriol; in the event of severe bowing, an osteotomy may be performed to correct the leg shape. The monoclonal antibody burosumab was first licensed in February 2018 by the European Medicines Agency, then licensed by the Food and Drug Administration in the United States of America in June 2018 as the first drug targeting the underlying cause for this condition.The leg deformity can be treated with Ilizarov frames and CAOS. It is also treated with medications including human growth hormone, calcitriol, and phosphate. Society and culture
