Anterosuperior Dislocation of the Shoulder Joint in an Older Patient with Parkinson's Disease
An 83-year-old woman, subsequently diagnosed with Parkinson's disease, fell onher right shoulder. Radiographs showed the humeral head dislocated anterosuperiorly.The supraspinatus tendon was massively disrupted and judged irreparable. Thesubscapularis tendon was repaired, however re-dislocation of the humeral head wasconfirmed after the surgery but further treatment was rejected as she was almost painfree and had a low activity level. The patient was followed up for one year after surgeryand her shoulder became almost pain-free, but range of motion with active elevationwas limited. In such cases a goal of absence or reduction of pain rather than real repairmight be considered appropriate

Age‐related reduction in the expression of FOXO transcription factors and correlations with intervertebral disc degeneration
Aging is a main risk factor for intervertebral disc (IVD) degeneration, the main cause of low back pain. FOXO transcription factors are important regulators of tissue homeostasis and longevity. Here, we determined the expression pattern of FOXO in healthy and degenerated human IVD and the associations with IVD degeneration during mouse aging. FOXO expression was assessed by immunohistochemistry in normal and degenerated human IVD samples and in cervical and lumbar IVD from 6-, 12-, 24-, and 36-month-old C57BL/6J mice. Mouse spines were graded for key histological features of disc degeneration in all the time points and expression of two key FOXO downstream targets, sestrin 3 (SESN3) and superoxide dismutase (SOD2), was assessed by immunohistochemistry. Histological analysis revealed that FOXO proteins are expressed in all compartments of human and mouse IVD. Expression of FOXO1 and FOXO3, but not FOXO4, was significantly deceased in human degenerated discs. In mice, degenerative changes in the lumbar spine were seen at 24 and 36 months of age whereas cervical IVD showed increased histopathological scores at 36 months. FOXO expression was significantly reduced in lumbar IVD at 12-, 24-, and 36-month-old mice and in cervical IVD at 36-month-old mice when compared with the 6-month-old group. The reduction of FOXO expression in lumbar IVD was concomitant with a decrease in the expression of SESN3 and SOD2. These findings suggest that reduced FOXO expression occurs in lumbar IVD during aging and precedes the major histopathological changes associated with lumbar IVD degeneration. © 2017 Orthopaedic Research Society.

FOXO are required for intervertebral disk homeostasis during aging and their deficiency promotes disk degeneration
Intervertebral disk (IVD) degeneration is a prevalent age-associated musculoskeletal disorder and a major cause of chronic low back pain. Aging is the main risk factor for the disease, but the molecular mechanisms regulating IVD homeostasis during aging are unknown. The aim of this study was to investigate the function of FOXO, a family of transcription factors linked to aging and longevity, in IVD aging and age-related degeneration. Conditional deletion of all FOXO isoforms (FOXO1, 3, and 4) in IVD using the Col2a1Cre and AcanCreER mouse resulted in spontaneous development of IVD degeneration that was driven by severe cell loss in the nucleus pulposus (NP) and cartilaginous endplates (EP). Conditional deletion of individual FOXO in mature mice showed that FOXO1 and FOXO3 are the dominant isoforms and have redundant functions in promoting IVD homeostasis. Gene expression analyses indicated impaired autophagy and reduced antioxidant defenses in the NP of FOXO-deficient IVD. In primary human NP cells, FOXO directly regulated autophagy and adaptation to hypoxia and promoted resistance to oxidative and inflammatory stress. Our findings demonstrate that FOXO are critical regulators of IVD homeostasis during aging and suggest that maintaining or restoring FOXO expression can be a therapeutic strategy to promote healthy IVD aging and delay the onset of IVD degeneration

Paraesophageal hernia repair: a curative consideration for chronic anemia?
Introduction
Chronic anemia is a common, coinciding or presenting diagnosis in patients with paraesophageal hernia (PEH). Presence of endoscopically identified ulcerations frequently prompts surgical consultation in the otherwise asymptomatic patient with anemia. Rates of anemia resolution following paraesophageal hernia repair (PEHR) often exceed the prevalence of such lesions in the study population. A defined algorithm remains elusive. This study aims to characterize resolution of anemia after PEHR with respect to endoscopic diagnosis.
Materials and methods
Retrospective review of a prospectively maintained database of patients with PEH and anemia undergoing PEHR from 2007 to 2018 was performed. Anemia was determined by preoperative labs: Hgb < 12 mg/dl in females, Hgb < 13 mg/dl in males, or patients with ongoing iron supplementation. Improvement of post-operative anemia was assessed by post-operative hemoglobin values and continued necessity of iron supplementation.
Results
Among 56 identified patients, 45 were female (80.4%). Forty patients (71.4%) were anemic by hemoglobin value, 16 patients (28.6%) required iron supplementation. Mean age was 65.1 years, with mean BMI of 27.7 kg/m

. One case was a Type IV PEH and the rest Type III. 32 (64.0%) had potential source of anemia: 16 (32.0%) Cameron lesions, 6 (12.0%) gastric ulcers, 12 (24.0%) gastritis. 10 (20.0%) had esophagitis and 4 (8%) Barrett’s esophagus. 18 (36%) PEH patients had normal preoperative EGD. Median follow-up was 160 days. Anemia resolution occurred in 46.4% of patients. Of the 16 patients with pre-procedure Cameron lesions, 10 (63%) had resolution of anemia. Patients with esophagitis did not achieve resolution. 72.2% (13/18) of patients with no lesions on EGD had anemia resolution (
p
= 0.03).
Conclusion
Patients with PEH and identifiable ulcerations showed 50% resolution of anemia after hernia repair. Patients without identifiable lesions on endoscopy demonstrated statistically significant resolution of anemia in 72.2% of cases. Anemia associated with PEH adds an indication for surgical repair with curative intent
