Innovative technique to reduce incidence of Frey\u27s syndrome after parotid surgery.

Frey\u27s syndrome was first described by Lucia Frey, a Polish neurologist in 1923. It is well accepted that it involves injury to the branches of the auriculotemporal nerve with subsequent aberrant regeneration. Due to this abnormal communication, the skin glands and vessels are always stimulated at the same time as eating and mastication, which results in symptoms such as flushing and sweating. The incidence of Frey\u27s syndrome in the literature has been variously described from 6 to 96 per cent. We analyzed the chart of 18 patients who had parotidectomy from March 2002 to December 2009. All procedures were performed by a single surgeon at the same facility. A total of 16 superficial and three total parotidectomies were done; one patient had bilateral parotidectomy. Oxidized regenerated cellulose (Interceed) was used after 10 surgeries (study group) and no adjuvant was used after nine surgeries (control group). All of the surgeries were done using similar technique. All the patients were followed-up with for a period of about 6 months postoperatively. The absolute risk reduction associated with the placement of an Interceed was 11 per cent. The small number of cases (n = 19) and an empty cell limits statistical analysis (a Fisher\u27s exact test revealed a P value of 0.44). Clearly the low number of procedures restricted the power to test these differences. The development of Frey\u27s syndrome is a very disabling but under-reported complication. The placement of a temporary barrier like Interceed may help in the prevention of Frey\u27s syndrome without increasing any complications

Site-Specific Fascial Defects in the Diagnosis and Surgical Management of Enterocele.

OBJECTIVE: The aim of this study was to assess the surgical feasibility and clinical outcomes of a vaginal enterocele repair that was based on the theory of site-specific defects in the vaginal fascia. STUDY DESIGN: Seventeen patients during a 2-year period with a diagnosis of enterocele and vaginal vault descensus with or without coexisting rectocele underwent surgical correction with a site-specific fascial defect repair. An enterocele was defined as vaginal wall prolapse seen during the operation in which the peritoneum was found to be in direct contact with the vaginal epithelium, with no intervening fascia. Patients were examined at 4 weeks after the operation and then at 6-month intervals, with site-specific analysis of pelvic prolapse at the vaginal apex and posterior vaginal segment. RESULTS: Identification and site-specific fascial defect repair of the enterocele were successfully performed in all 17 cases. All patients also underwent a uterosacral ligament vaginal vault suspension, and 15 patients (88%) underwent concurrent posterior colporrhaphy. There were no intraoperative complications. At a mean follow-up of 6.3 months (range 1-17 months), 2 patients (12%) had mild, asymptomatic vaginal vault descensus but no patients (0/17) had evidence of a recurrent enterocele or rectocele. CONCLUSION: Enterocele correction through a fascial defect repair is easily performed through the vaginal route and is associated with excellent surgical outcomes on short-term follow-up

Sickle Cell Disease—Genetics, Pathophysiology, Clinical Presentation and Treatment

Sickle cell disease (SCD) is a monogenetic disorder due to a single base-pair point mutation in the β-globin gene resulting in the substitution of the amino acid valine for glutamic acid in the β-globin chain. Phenotypic variation in the clinical presentation and disease outcome is a characteristic feature of the disorder. Understanding the pathogenesis and pathophysiology of the disorder is central to the choice of therapeutic development and intervention. In this special edition for newborn screening for haemoglobin disorders, it is pertinent to describe the genetic, pathologic and clinical presentation of sickle cell disease as a prelude to the justification for screening. Through a systematic review of the literature using search terms relating to SCD up till 2019, we identified relevant descriptive publications for inclusion. The scope of this review is mainly an overview of the clinical features of pain, the cardinal symptom in SCD, which present following the drop in foetal haemoglobin as young as five to six months after birth. The relative impact of haemolysis and small-vessel occlusive pathology remains controversial, a combination of features probably contribute to the different pathologies. We also provide an overview of emerging therapies in SCD
