(b) Superior rib notching is usually manifested by longer erosions than are seen interiorly. Its most common causes are rheumatoid cystic bursae occurring between the ribs, other collagen diseases, radiation damage and hyperparathyroidism. Other causes include poliomyelitis and chronic palsies, including traumatic quadriplegia, the effects of localised pressure, restrictive lung disease and? hypervitaminosis D.
Vitamins
Published in Stanley R. Resor, Henn Kutt, The Medical Treatment of Epilepsy, 2020
Prophylactic treatment may be beneficial for patients who are inactive, lack sufficient vitamin D in the daily usual diet, and are deprived of sunlight. After 6 months on AEDs such as PHT, PB, or CBZ, determination of calcium, phosphorus, and alkaline phosphatase levels is helpful. If there is suspicion of vitamin D deficiency, then a vitamin D level can also be measured. The average patient with epilepsy who is otherwise well on a normal diet probably does not need prophylactic vitamin D supplements. The symptoms of hypercalcemia from hypervitaminosis D or excessive calcium intake include weakness, nausea, vomiting, diarrhea, and obtundation. Nephrocalcinosis, nephrolithiasis, and metastatic calcification can ensue (29). If vitamin D or calcium is prescribed, then monitoring of the calcium, phosphorus, alkaline phosphatase, and creatinine should be done after a month, then every 3 months. Vitamin D and circulating 25-hydroxyvitamin D levels should be checked 1 month after starting such therapy, and then every 6 months (30).

Tolerance to vitamin D is variable. Hypervitaminosis D may cause hypercalciuria (increased calcium levels in the urine, -uria) or hypercalcemia (-emia, blood) with symptoms of weakness, anorexia, vomiting, diarrhea, excessive thirst (polydipsia), excessive urination (polyuria), mental changes and proteinuria. Because of vitamin D's roie in calcium utilization, deposits of calcium salts in soft tissue may result if the condition is prolonged. Chronic overdosage of vitamin D can lead to irreversible renal failure.

Vitamin D toxicity should not be diagnosed solely on the basis of an elevated 25(OH)D level; it should rather be recognized as a clinical syndrome of both hypervitaminosis D and hypercalcemia, in which hyperphosphatemia and hypercalciuria also commonly occur. Patients with vitamin D toxicity can present with clinical symptoms (e.g., headache, metallic taste, nausea, and vomiting) and complications of hypercalcemia (e.g., dehydration, constipation, pancreatitis, and heart arrhythmias) and hypercalciuria (e.g., polyuria and kidney stones) (National Institute of Health 2016). While hypervitaminosis D in the absence of hypercalcemia may prompt further investigation to evaluate the etiology of increased vitamin D levels, it is not a medical emergency as is hypercalcemia.

In the present study, none of the participants developed hypervitaminosis D (i.e. 25-OH vitamin D ≥ 100 ng/mL) [23] or experienced any serious adverse event. The most common side effects were myalgia and conjunctivitis. The other side effects found in the present study included loss of appetite, fever-like symptoms, thirstiness, and nausea. None of the side effects caused participants’ withdrawal from the study. Therefore, the safety of vitamin D2 supplementation with ergocalciferol 40,000 IU/week for 12 weeks was assured.

Ketha et al described a case of hypervitaminosis D due to a dispensing error, where the contents of the supplement were found to be threefold the listed values.6 This resulted in vitamin D toxicity and hypercalcemia in an infant.
