Thermography by Specialty
Published in James Stewart Campbell, M. Nathaniel Mead, Human Medical Thermography, 2023
James Stewart Campbell, M. Nathaniel Mead
PsD is associated with psoriatic arthritis (PsA), with up to 30% of dermal cases developing PsA. Though any joint may be involved, the distal interphalangeal joints of the hands and feet are most often affected. PsA generally appears asymmetrically in the limbs, sacroiliac joints, or spine. Often it follows the same course as the skin lesions. Active PsA can often be detected by static thermography. Mild isometric exercise increases the thermal contrast over inflamed joints.48 More investigations of the thermal findings of PsA are needed, including studies of the acute and chronic effects of therapy.
The wrist and hand
Published in David Silver, Silver's Joint and Soft Tissue Injection, 2018
These are simple joints, but it must be remembered that the joint space of the metacarpal joint is distal to the knuckle on palpation and is a condylar joint, with one palmar and two collateral ligaments. The interphalangeal joints are simple hinge joints, each with a palmar and two collateral ligaments. It is important to remember the neurovascular bundle at the side of each joint when injecting.

As its name indicates, the metacarpophalangeal joint is a joint between the metacarpals and the phalanges of the hand. This joint allows flexion, extension, abduction, and adduction of the proximal phalanges and thus of the digits as a whole. Lastly, between the phalanges are interphalangeal joints (only one in the thumb, but two—proximal and distal—in the other digits). These joints only allow flexion and extension of the middle and distal phalanges.

A 31-year-old patient presented to laboratory investigation with an 8 years history of pelvic endometriosis-associated infertility. The history of the patient reveals the presence of ecchymosis since the age of 8, but platelet count was normal (400 G/L). Menorrhagia started at menarche (14 years old). Diagnosis of ITP was established at the age of 23, on the basis of an isolated and asymptomatic thrombocytopenia (platelet count 40 G/L). Initial assessment found positive antinuclear antibodies (1/640, speckled), anti SSA and anti SSB antibodies. Serum protein electrophoresis showed polyclonal hypergammaglobulinemia. Bone marrow smear confirmed the peripheral mechanism of thrombocytopenia. The thrombocytopenia was corticosteroid responsive. Four years later, the patient presented with inflammatory arthralgias, concerning wrists, elbows, then ankles and shoulders. The clinical examination found arthritis of the proximal interphalangeal joints of the second and third fingers of the left hand, as well as of the thumb spine, and a limitation of shoulder’s amplitudes. Symptoms of the Sjögren syndrome (SS) resolved after short oral corticosteroid therapy. Treatment with hydroxychloroquine 200 mg ×2/day was initiated to control arthralgias.

The AMMR full-body model was used as a basis. Only the forearm and hand were modified. For the proposed detailed hand model, 22 hand segments (including ulna and radius) modelled as rigid bodies linked by physiological idealized joints were used, allowing 31 DOF. The joints of the distal interphalangeal (DIP) and proximal interphalangeal (PIP) were modelled as revolute joints for flexion/extension movements and the metacarpophalangeal (MCP) joint as a universal joint. Hereby flexion/extension and ab/adduction were achieved. Joint positioning and orientation was acchieved in accordance to literature studies (An et al. 1979; Buchholz et al. 1992) and an anatomical study by the UWB (Havelkova et al. 2020b), following the International Society of Biomechanics recommendations for joint coordinate systems (Wu et al. 2005). Further, the axes of rotation of the thumb’s joints were modeled in separated revolute joints as depicted by Hollister et al. (1995). To reduce the complexity, the carpal bones were treated as one rigid body as in other models described in the literature (Lee et al. 2015b; Mirakhorlo et al. 2018; Ma’touq et al. 2019). The wrist joint has two rotational axes according to Kobayashi et al. (1997), which implies flexion/extension and ab/adduction.
New insights into the progression from cutaneous lupus to systemic lupus erythematosus

Arthralgias, arthritis and other musculoskeletal symptoms in proximal interphalangeal joints and knees are extracutaneous symptoms most commonly observed in patients progressing to SLE [29,30]. More than half of patients with SCLE are followed in the long-term and the result shows that they suffer from mild musculoskeletal symptoms such as myalgia and arthralgia [31]. 46 SLE patients concomitant with SCLE and 66 SCLE patients without SLE were investigated in a study where 45.7% of the patients with both SCLE and SLE as well as 1.5% of the SCLE-only patients had arthritis. Likewise, 60.9% of the patients suffering SLE and SCLE were afflicted with arthralgias in comparison with 18.2% of the people who only had SCLE [32]. The involvement of the skeleton and muscle is typically symmetric with occasional morning stiffness.
