Overview
Historical Perspective
- [Disease name] was first discovered by [scientist name], a [nationality + occupation], in [year] during/following [event].
- In [year], [gene] mutations were first identified in the pathogenesis of [disease name].
- In [year], the first [discovery] was developed by [scientist] to treat/diagnose [disease name].
Classification
- [Disease name] may be classified according to [classification method] into [number] subtypes/groups:
- [group1]
- [group2]
- [group3]
- Other variants of [disease name] include [disease subtype 1], [disease subtype 2], and [disease subtype 3].
Pathophysiology
- The pathogenesis of calcium apatite deposition disease is not clear. Various authors have formulated the different hypothesis about the pathophysiology of calcium apatite deposition disease.
- Uhthoff and Loebr described the pathogenesis in four phases: precalcific, formative, resorptive, and postcalcific.[1]
- Precalcific phase: In this stage, collagen fibers of the tendon is undergoing metaplasia into fibrocartilage tissue.
- Formative phase: Chondrocytes start depositing within the areas of fibrocartilage formation which further leads to the formation of calcified apatite crystals.
- After the formative phase sometimes it will go into the resting phase for long period of time.
- Resorptive phase: Calcification will further undergo to an inflammatory resorptive phase, which is characterized by the appearance of leukocytes, lymphocytes, and giant cells leading to the formation of a calcium granuloma.
- Postcalcific phase: Reparative process allows new capillary and collagen fiber formation that is when calcification enters the postcalcific phase.
- The HLA-A1 gene has been associated with the development of calcium apatite deposition disease.[2]
- On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
- On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Differentiating [disease name] from other Diseases
- Calcium apatite deposition disease must be differentiated from the following disease:
- Calcium pyrophosphate dihydrate deposition disease (CPPD)
- Dystrophic calcification
- Renal osteodystrophy
- Hyperparathyroidism
- Hypoparathyroidism
- Collagen vascular disease
- Milk-alkali syndrome
- Hypervitaminosis D
Epidemiology and Demographics
- The prevalence of [disease name] is approximately [number or range] per 100,000 individuals worldwide.
- In [year], the incidence of [disease name] was estimated to be [number or range] cases per 100,000 individuals in [location].
he prevalence rates of 7.8% in asymptomatic patients and 42.5% in patients with SAPS provide a current view on the epidemiology of calcific deposits in the rotator cuff.
Age
- Calcium apatite deposition disease is more commonly observed among patients aged of 30–60 years old.[3]
- Calcium apatite deposition disease is also observed among 3 years old.[4]
Gender
- Women are more commonly affected with calcium apatite deposition disease than men.[3]
Race
- There is no racial predilection for [disease name].
- [Disease name] usually affects individuals of the [race 1] race.
- [Race 2] individuals are less likely to develop [disease name].
Risk Factors
- Common risk factors in the development of [disease name] are [risk factor 1], [risk factor 2], [risk factor 3], and [risk factor 4].
Natural History, Complications and Prognosis
- The majority of patients with [disease name] remain asymptomatic for [duration/years].
- Early clinical features include [manifestation 1], [manifestation 2], and [manifestation 3].
- If left untreated, [#%] of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
- Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
- Prognosis is generally [excellent/good/poor], and the [1/5/10year mortality/survival rate] of patients with [disease name] is approximately [#%].
Diagnosis
Diagnostic Criteria
- The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met:
- [criterion 1]
- [criterion 2]
- [criterion 3]
- [criterion 4]
Symptoms
- Patients with calcium apatite deposition disease are usually asymptomatic.
- Patients usually experience acute episodes of pain to chronic mild pain.
- Acute episodes of pain usually resolve spontaneously but there are recurrent episodes after an initial episode.[5]
- Acute episodes are usually associated with warmth and swelling.
- Some patients also present with the symptoms of neuropathy.[6]
Physical Examination
- Patients with calcium apatite deposition disease usually appear fatigue and usually in pain.
- Physical examination of the involved joint is remarkable for:
- Redness
- Swelling
- The restricted range of movement
- Some patients show signs of neuropathy such as reduced power, decreased sensation and reflexes.
Laboratory Findings
- There are no specific laboratory findings associated with [disease name].
- A [positive/negative] [test name] is diagnostic of [disease name].
- An [elevated/reduced] concentration of [serum/blood/urinary/CSF/other] [lab test] is diagnostic of [disease name].
- Other laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].
Imaging Findings
- There are no [imaging study] findings associated with [disease name].
- [Imaging study 1] is the imaging modality of choice for [disease name].
- On [imaging study 1], [disease name] is characterized by [finding 1], [finding 2], and [finding 3].
- [Imaging study 2] may demonstrate [finding 1], [finding 2], and [finding 3].
Other Diagnostic Studies
- [Disease name] may also be diagnosed using [diagnostic study name].
- Findings on [diagnostic study name] include [finding 1], [finding 2], and [finding 3].
Treatment
Medical Therapy
- There is no treatment for [disease name]; the mainstay of therapy is supportive care.
- The mainstay of therapy for [disease name] is [medical therapy 1] and [medical therapy 2].
- [Medical therapy 1] acts by [mechanism of action 1].
- Response to [medical therapy 1] can be monitored with [test/physical finding/imaging] every [frequency/duration].
Surgery
- Surgery is the mainstay of therapy for [disease name].
- [Surgical procedure] in conjunction with [chemotherapy/radiation] is the most common approach to the treatment of [disease name].
