As medical care progresses, patients with intellectual and developmental disabilities are living longer and beginning to experience diseases that commonly afflict the aging population, such as osteoporosis. Osteoporosis and resultant fractures increase disability and threaten the independence of this vulnerable population. In addition, the diagnosis, prevention, and management of osteoporosis present unique challenges in these patients. Critical preventive targets include exercise modification, fall prevention, and monitoring for nutrient deficiencies. Commonly used in diagnosis and treatment monitoring, dual-energy x-ray absorptiometry (DXA) scan of the hip and spine may not be feasible, whereas peripheral DXA or computed tomography may be more accessible for patients with physical disabilities. Pharmacological treatment should be tailored to the individual patient, considering factors such as adherence and comorbidities. Finally, bone turnover markers are a noninvasive, cost-effective option for monitoring treatment response in patients who cannot undergo DXA.

The purpose of this literature review is to address the diagnosis and treatment of upper gastrointestinal (GI) disorders in patients with intellectual and developmental disabilities (IDD). Manifestations of upper GI dysmotility and disorders include dysphagia, pulmonary aspiration, malnutrition, gastroesophageal reflux, and gastritis, all of which can impact a person's quality of life and lead to chronic, life-threatening conditions. This article will explore the existing diagnostic methods and treatments for gastrointestinal disorders as they relate to patients with IDD.

Intellectual disability (ID) encompasses a wide variety of disorders that can severely affect an individual’s cognitive, social, emotional, and physical development, even when identified early in life. Initially, individuals with such disorders had shorter life expectancies. However, medical advances have increased the life expectancy of individuals with ID similar to that of the general population. More attention must be paid to manage diseases affecting the intellectually disabled elderly, such as diabetes, cardiovascular disease, chronic constipation, and behavioral disorders.

A 33-year-old woman with history of HIV presented with 4 months of gradually progressing right hip pain and was found to have avascular necrosis (AVN) of both femoral heads. She had no other risk factors for AVN including sickle cell disease, systemic lupus erythematosus, prolonged steroid used or trauma. She initially failed conservative management and ultimately had bilateral hip core decompressions. After decompression therapy, the left femoral head collapsed and patient underwent a left total hip arthroplasty. Her postsurgical course was complicated by the left sciatic nerve neuropathy for which she is currently being managed with duloxetine. She has yet to follow-up with her orthopaedic surgeon for further evaluation.

A 67-year-old female with a relapse of multiple myeloma after being in remission for approximately 2 years following autologous stem cell transplant presented with worsening pancytopenia, over a three-month period. There were an increase in her monoclonal spike at 3.13 g/dL on serum protein electrophoresis, low serum B12 levels, and positive intrinsic factor antibodies. Three months before, she had normal B12 levels and a significantly lower monoclonal spike of 1.07 g/dL. She was diagnosed with B12 deficiency with pernicious anaemia in the setting of her worsening myeloma. Multiple myeloma (MM) has been linked with B12 deficiency and pernicious anaemia. Several mechanisms have been described regarding the pathogenesis of B12 deficiency in such patients. Increased tumour activity can further perpetuate the development of B12 deficiency in such patients. With regard to our case, the increase in tumour activity and onset of pernicious anaemia could have contributed to the rapid development of B12 deficiency. In contrast to this, rapid development of B12 deficiency could also signify relapse or worsening of the myeloma as seen in our case. Physicians ought to consider B12 deficiency in patients with worsening pancytopenia and myeloma.

Skin rashes are infrequently encountered in the intensive care units, either as a result or as a cause of admission. The entities of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) form a spectrum of desquamating skin diseases that have multiple etiologies, the most common being drug-related reactions; very rarely, the cause may be cutaneous malignancies. We herein present a unique case of a 54-year-old male patient with psoriasis treated with methotrexate, who presented with a cellulitis-like clinical picture, then developed a severe progressive systemic inflammatory response syndrome, and progressed clinically to SJS, then TEN even after discontinuing the antibiotics and methotrexate. A skin biopsy demonstrated an aggressive and rapidly-progressing T-cell lymphoma. The present case highlights the necessity of skin biopsy when encountering SJS and TEN in the ICU in order to identify potentially treatable/controllable causes. Although it appeared reasonable to correlate TEN solely to medications, the skin biopsies clearly demonstrated an aggressive T-cell skin lymphoma. In a patient with a better general condition it may have been helpful to treat this malignancy. TEN is a life-threatening condition and skin biopsy is the cornerstone of diagnosis, despite the presence of multiple risk factors and the typical physical findings of a drug-induced reaction.
