Germ cell arrest associated with aSETX mutation in ataxia oculomotor apraxia type 2
We describe the first case of human male infertility caused by germ cell arrest in a man with AOA2. Our patient has a homozygous mutation in the SETX gene (NC_000009.11:g.135158775dup), which results in a frameshift and premature protein termination (NM_015046.6:c.6422dup, p.[Ser2142Glufs*23]). In accordance with the murine phenotype, testis histology revealed disrupted seminiferous tubules with spermatogonia and primary spermatocytes, but absent spermatids. Collectively, these data support an essential role of senataxin in human spermatogenesis, and provide a compelling case that men with AOA2 should be counselled at diagnosis about the possibility of infertility.

CONCLUSIONS: Testosterone deficiency in male individuals after TBI can be present after TBI or can develop during aging. Age-related decreases in testosterone production after TBI may act to amplify endocrine dysfunction after TBI. Ongoing clinical surveillance for testosterone deficiency associated with both TBI and aging may be reasonable. PMID: 32497444 [PubMed - as supplied by publisher]
We report a case of a 65-year old Caucasian man with a slow and painful recovery after arthroscopic shoulder surgery encompassing rotator cuff repair, biceps tenotomy and acromioplasty, with recurrence of impingement symptoms unresponsive to conservative therapy (physiotherapy and one sub- acromial injection). He developed a severe heterotopic ossification at the acromial insertion of the deltoid and in the coraco-acromial ligament. This was successfully treated by arthroscopic excision of the lesion and postoperative prophylactic therapy with nonsteroidal anti-inflammatory drugs. PMID: 32490788 [PubMed - in process]

CONCLUSIONS: it is very important to establish an early diagnosis for patients with Boerhaave's syndrome. Early ( 24 h) primary repair, even for those reinforced with vascular muscle flaps. Furthermore, repair reinforcement with different muscle flaps appears to render similar results for patients with delayed diagnosis. PMID: 32496118 [PubMed - as supplied by publisher]
Abstract PURPOSE: To evaluate the in vivo response of photobiomodulation therapy associated with norbixin-based poly(hydroxybutyrate) membrane (PHB) in tenotomized calcaneal tendon. METHODS: Thirty rats were randomly allocated to six groups (n=5 each): LED groups (L1, L2 and L3) and membrane + LED groups (ML1, ML2 and ML3). The right calcaneal tendons of all animals were sectioned transversely and were irradiated with LED daily, one hour after surgery every 24 hours, until the day of euthanasia. At the end of the experiments the tendons were removed for histological analysis. RESULTS: The histological an...
Conclusion: This study will provide helpful reference for the efficacy and safety of AM for the treatment of patients with EDPN to the clinicians and further studies. Study registration number: INPLASY202040094.
Nonobstructive azoospermia (NOA) is a severe form of male infertility. The molecular basis of NOA is still poorly understood. The aim of this study was to explore the associations between single nucleotide polymorphisms (SNPs) of the TATA-box binding protein associated factor 4b (TAF4B) gene and NOA. A total of 100 Han Chinese patients with NOA and 100 healthy men as controls were recruited. Targeted gene capture sequencing was performed. A total of 11 TAF4B SNPs were screened in the NOA and control subjects. Six synonymous and 4 nonsynonymous variants were detected. The c.11G>T (p.G4V) mutation was detected only in NOA...
