Chronic drooling is a major problem in patients with cerebral palsy and other neurological dysfunctions. Various treatments, ranging from speech therapy to radical surgery, have been used to overcome this distressing problem, with surgery the most consistently successful. In this study, we used a new surgical technique to manage severe drooling. This involved the dissection of both parotid-duct orifices, and their relocation, via a submucosal tunnel, into the tonsillar pillar using autologous vein grafts. Four patients were treated using this technique together with bilateral submandibular duct rerouting. The results were analysed by subjective judgements of drooling and retrograde sialography at 90 days postoperatively. In all cases, salivary flow was reduced and drooling was significantly improved. Retrograde sialography revealed no signs of obstruction or stricture formation in any of the cases. No postoperative complications occurred. These preliminary results suggest that the bilateral surgical transposition of Stensen's ducts into the tonsillar pillar using autologous vein grafts together with bilateral submandibular duct rerouting can provide effective control of chronic drooling.

Spontaneous true brachial artery aneurysm: A case report from Somalia.
Int J Surg Case Rep
January 2025
Introduction And Importance: True brachial artery aneurysms are rather uncommon, due to their number of etiological factors. Besides inducing symptoms such as hand or digit ischemia, they may present as pulsative tumefactions and cause pain or paresthesias through nerve impingement. The diagnosis is based on duplex ultrasonography, CTA in the operational planning phase, and a physical examination.

Carotid artery stenting (CAS) has become a favoured alternative to surgical carotid endarterectomy (CEA) in select cases of critical internal carotid artery (ICA) occlusion. However, complications such as stent migration or entrapment can occur, necessitating prompt diagnosis and intervention. We present a case of a 75-year-old diabetic male who underwent CAS for recurrent presyncope at a private hospital, and during the procedure of CAS the stent was migrated and its proximal part was impacted in the critically narrowed part of the ICA.

Background: Repair of the regurgitant bicuspid aortic valve is an attractive alternative to valve replacement. Although good long-term outcomes have been reported, postoperative aortic stenosis remains a major late cause of repair failure in bicuspid aortic valves. Sinus plication is effective for creating a more symmetrical commissural angle, leading to a decrease in the mean transvalvular pressure gradient.

Background: Spinal tuberculosis is a common cause of spinal deformity and neurological dysfunction, with surgical treatment being crucial in severe cases. This study evaluates the efficacy and safety of combined anterior and posterior surgery with autologous tricortical iliac bone and rib grafting for treating spinal tuberculosis.
Methods: We included 61 patients with thoracic tuberculosis, who underwent a surgical procedure involving initial posterior correction, followed by anterior debridement and reconstruction with autologous tricortical iliac bone and rib grafts.
Mesenchymal Stem/Stromal Cells Reverse Adipose Tissue Inflammation in Pigs with Metabolic Syndrome and Renovascular Hypertension.

Metabolic syndrome (MetS) is associated with low-grade inflammation, which can be exacerbated by renal artery stenosis (RAS) and renovascular hypertension, potentially worsening outcomes through pro-inflammatory cytokines. This study investigated whether mesenchymal stem/stromal cells (MSCs) could reduce fat inflammation in pigs with MetS and RAS. Twenty-four pigs were divided into Lean (control), MetS, MetS + RAS, and MetS + RAS + MSCs.
