Zuckerkandl's tubercle of the thyroid gland in association with pressure symptoms: a coincidence or consequence?

BACKGROUND: The Zuckerkandl's tubercle (ZT) of the thyroid gland is a well-described anatomical landmark, but few studies have clearly defined its association with pressure symptoms. METHODS: Sixty-six consecutive patients who had primary thyroid surgery were prospectively included in the present study between late January and early August 1998. RESULTS: A total of 96 capsular dissections were performed at thyroid surgery. Grades two and three ZT were recognized in 77 (80.2%) dissections. In general 49 (63.6%) of them were associated with significant pressure symptoms. In 43 (87.8%) of the dissections with pressure symptoms, grade 3 ZT was observed (mean weight of goitre: 154.8 g). Interestingly in this group, 16 (37.2%) patients with pressure symptoms had a goitre that was < 100 g and in one patient it was only 21 g. CONCLUSIONS: The pressure symptom of the thyroid gland does not always appear to be due to the large size of the goitre. In a relatively small-size goitre the ZT may cause significant pressure symptoms. Observations in the present study supported a strong association of enlarged ZT with pressure symptoms. We believe this is unlikely to be simply a coincidence but rather a consequence of the enlarged tubercle. Nonetheless a prospective randomized study is called for to allow meaningful and objective evidence to be drawn.     

Spontaneous breakage of intracorneal ring segments (ICRS) 8 years after implantation

We present a case of spontaneous in situ breakage of intracorneal ring segments (ICRSs) 8?years after their implantation in a patient with keratoconus. The patient presented to our clinic with a red and painful right eye that had not improved despite topical steroids and antibiotics. The decision was made to explant the broken ICRSs from the cornea and send them for laboratory analyses, by which manufacturer defects were excluded. It is noteworthy that corneal curvature re-steepening was observed 4?months after ICRS removal despite the performance of crosslinking (CXL) 1?year prior to ICRS implantation.     

Complications in paediatric liver transplant from Kuwait when transplanted abroad

Background and study aimsSince the introduction of liver transplantation (LTx) in children suffering from liver failure in 1963, many centres around the world have offered this service to children that have no other alternative. The aim of this retrospective study is to analyse the results of paediatric liver transplant in Kuwait over the last decade.Patients and methodsA retrospective chart review was done involving paediatric patients during the time period of 1995–2004. The information collected included patient demographics, indications for liver transplantation, survival of both patient and allograft, and complications.ResultsA total of 16 cases were found and analysed. The mean age was 3.6 years (ranged 5 months–17 years). There were nine boys and seven girls. The most common indications for LTx were biliary atresia and metabolic liver disease. All the liver transplants were done abroad. There were totally nine deceased donor and seven living related cases. The complications were acute cellular rejection in five, hypertension in two, biliary complications in four, cytomegalovirus (CMV) infection in three and post lymphoproliferative disease in two cases. All but one patient are presently alive.ConclusionThe above information demonstrates that LTx in Kuwati children is safe and improves the quality of life for those that would otherwise have no other alternative.
