Atlantoaxial rotatory fixation in a case of tubercular lymphadenitis.

Atlantoaxial fixation is a relatively rare cause of torticollis which may be easily missed in practice. Early diagnosis is important as this indicates a compromised atlantoaxial complex with the potential to cause neural damage or even death. Here, we report a case of atlantoaxial rotatory fixation in a 13 yr old male with torticollis for two years and history of defaulting treatment for tubercular lymphadenitis. In this case, the odontoid peg view revealed asymmetric distance between the odontoid and lateral mass of atlas which was confirmed with Fluoroscopy and Computed Tomography (CT) scan. Magnetic Resonance Imaging (MRI) was also done which showed hyperintensity in alar ligaments with posterior inclination of the odontoid peg along with cervical lymphadenopathy.

Urological complication after kidney transplantation.

BACKGROUND: Renal transplantation is a regular service at Tribhuvan University Teaching Hospital and complications have been known to occur after it. This study was conducted to assess complications after transplantation. OBJECTIVES: To determine the incidence of urological complications after living related renal transplantation at Tribhuvan University Teaching Hospital. METHODS: A clinical study was performed (from August 2008 to July 2010) which included 50 living-related renal transplantations at Tribhuvan University Teaching Hospital. All the donors and recipients were evaluated preoperatively with necessary investigations and followed up postoperatively with standard hospital transplant protocol. The incidence of urological complications were documented and analyzed. RESULTS: Fifty living-related, renal transplantations were carried out during the study period. Seven doors had minor post operative complications; three had post operative fever, two had chest infections and each one had superficial surgical site infections and severe pain at incision site. Ureteroneocystostomy was performed with double J stent in all recipients. Urological complications were noted in 12 (24%) recipients. Clinical significant hematuria occurred in four cases. One patient had ureteric necrosis and urinary leak which required re-exploration post operatively. Two patients developed delayed ureteric stricture which were managed by antegrade Double J stenting and ureteric reimplantation. Peri-graft abscess occurred in two cases, which were drained percutaneously. surgical site infections was seen in one case. CONCLUSIONS: Urological complications are inevitable in renal transplantation and our complications rate appears similar to that reported in literature.

Cervical rib causing thrombosis of subclavian artery.

We describe here an unusual case of thrombosis of left subclavian artery in a patient with cervical rib. The patient presented with features of ischaemia of left upper limb. X-ray chest revealed bilateral cervical ribs, longer on the left side. Color Doppler studies showed echogenic thrombus within the left subclavian artery. Angiography revealed complete occlusion of left subclavian artery. Embolectomy was done. She was planned for excision of rib.
