A rare mutation in hypophosphatasia: a case report of adult form and review of the literature.

Arch Endocrinol Metab 2019 Feb;63(1):89-93

Emory University School of Medicine, Diabetes and Endocrinology Section, Atlanta, GA, USA.

Hypophosphatasia is a rare inborn error of metabolism characterized by low serum alkaline phosphatase activity due to loss-of-function mutations in the gene encoding the tissue-nonspecific isoenzyme of alkaline phosphatase (TNSALP). Extracellular accumulation of TNSALP substrates leads to dento-osseous and arthritic complications featuring tooth loss, rickets or osteomalacia, and calcific arthopathies. Mild hypophosphatasia usually has autosomal dominant inheritance, severe cases are either autosomal recessive or due to a dominant negative effect. Read More

Acute pseudogout - Measure serum magnesium.

Ann Clin Biochem 2019 Feb 27:4563219826169. Epub 2019 Feb 27.

4 Blood Sciences, The Royal Wolverhampton NHS Trust, Wolverhampton, UK.

We report a 49-year-old woman with an acute swollen left knee due to acute pseudogout with chondrocalcinosis as a presenting feature of Gitelman syndrome due a novel homozygous mutation of the SLC12A3 gene. This report highlights the under-recognized importance of excluding metabolic disease, including Gitelman syndrome, in younger patients whose sole presenting feature may be chondrocalcinosis with or without pseudogout, as this may impact on management and risk of further episodes. We also suggest that chondrocalcinosis and hypomagnesaemia with or without hypokalaemia are diagnostic of Gitelman syndrome. Read More

Latissimus dorsi muscle transfer reduces external rotation deficit at the cost of internal rotation in reverse shoulder arthroplasty patients: a cohort study.

J Shoulder Elbow Surg 2019 Jan 14;28(1):56-64. Epub 2018 Sep 14.

Upper Extremities Department, Schulthess Clinic, Zürich, Switzerland; Research and Development Department, Schulthess Clinic, Zürich, Switzerland. Electronic address:

Hypothesis: We hypothesized that treatment of rotator cuff arthropathy (RCA) with reverse shoulder arthroplasty (RSA) and an additional latissimus dorsi transfer (LDT) in patients with an active external rotation deficit (ERD) would restore external rotation (ER) with concomitant deterioration in internal rotation.

Methods: In our cohort study, 26 RCA patients with an active ERD (ie, positive lag sign and maximum active ER of 0°) underwent RSA between September 2007 and February 2015; LDT was completed in 13 of these patients. In addition, 88 control patients without ERD who underwent only RSA were identified. Read More

[Update on Gout and Calcium pyrophosphate deposition (CPPD)].

Dtsch Med Wochenschr 2018 Aug 7;143(16):1157-1166. Epub 2018 Aug 7.

The metabolic diseases gout and calciumpyrophosphate deposition (CPPD) (formerly: chondrocalcinosis/pseudogout) are crystal arthropathies which are caused by crystals in synovial fluid and in the case of gout also in periarticular structures. Today, in particular gout is considered as an auto-inflammatory process since phagocytosis of monosodium urate crystals by monocytes/macrophages results in the activation of the innate immune system by activation of the NRLP3-Inflammasome and consecutive secretion of the key cytokine interleukin-1ß and other pro-inflammatory cytokines. The prevalence of both crystal arthropathies rises with increasing age of patients. Read More

The "tipping point" for 931 elective shoulder arthroplasties.

J Shoulder Elbow Surg 2018 Sep 7;27(9):1614-1621. Epub 2018 May 7.

Department of Orthopaedics and Sports Medicine, University of Washington, Seattle, WA, USA. Electronic address:

Background: A patient with arthritis usually experiences the progression of symptoms over time. At some stage, the patient may decide that the symptoms have reached a level of severity that leads him or her to elect to proceed with joint replacement; we refer to this degree of symptom severity as the "tipping point." Our goal was to study the factors that influenced the tipping point for patients undergoing elective shoulder arthroplasty. Read More

Inhibition of nucleotide pyrophosphatase/phosphodiesterase 1: implications for developing a calcium pyrophosphate deposition disease modifying drug.

Rheumatology (Oxford) 2018 08;57(8):1472-1480

Department of Rheumatology, Tel Aviv University, Tel Aviv, Israel.

Objectives: Calcium pyrophosphate deposition (CPPD) is associated with osteoarthritis and is the cause of a common inflammatory articular disease. Ecto-nucleotide pyrophosphatase/phosphodiesterase 1 (eNPP1) is the major ecto-pyrophosphatase in chondrocytes and cartilage-derived matrix vesicles (MVs). Thus, eNPP1 is a principle contributor to extracellular pyrophosphate levels and a potential target for interventions aimed at preventing CPPD. Read More

Therapy for CPPD: Options and Evidence.

Curr Rheumatol Rep 2018 Apr 19;20(6):31. Epub 2018 Apr 19.

Instituto de Investigación Sanitaria y Biomédica de Alicante (ISABIAL), Universidad Miguel Hernández, Alicante, Spain.

Purpose Of Review: Current evidence and accumulated experience for the management of calcium pyrophosphate deposition disease (CPPD) are presented.

Recent Findings: Contrary to other rheumatic inflammatory conditions that account for high interest and growing research, advances in treating CPPD are still very limited and mostly derive from those achieved in gout. Once formed, calcium pyrophosphate crystals cannot be dissolved; therefore, management relies on the control of crystal-derived inflammation. Read More
