No effect of long-term valproate therapy on thyroid and parathyroid functions in children

In this study, we studied serum calcium, phosphorus, alkaline phosphatase, thyroid hormones (total thyroxine, free thyroxine, thyroid-stimulating hormone), parathyroid hormone, and osteocalcine levels in children with epilepsy who had been receiving long-term valproate (VPA) therapy in order to determine whether there was any effect of VPA therapy on these hormones. The study included 31 patients with epilepsy receiving VPA and 22 healthy age-matched controls. The age ranged from 15 months to 16 years and 18 months to 17 years in the study and control group, respectively. The duration of VPA use was between 12 months and 5 years (1.93 +/- 1.90 years). When comparing the results, we did not find any significant difference in any of the parameters, including serum calcium, phosphorus, alkaline phosphatase, osteocalcine, and thyroid and parathyroid hormone levels, between the study and control group. We suggest that VPA can safely be used with regard to thyroid and parathyroid dysfunction in childhood epilepsy.     

Situs inversus and coronary artery disease

Situs inversus is a rare condition and there are few reports of myocardial revascularization in such patients. A 56-year-old woman with situs inversus totalis and coronary artery disease underwent successful anastomosis of the right internal mammary artery to the anterior descending coronary artery, and a saphenous vein graft to the right coronary artery.     

Video-assisted extracorporeal appendectomy

BACKGROUND: Despite many randomized controlled trials, there are still several important doubts about laparoscopic appendectomy. Longer operative time and greater cost are the two major disadvantages of the laparoscopic technique. PATIENTS AND METHODS: In current techniques of laparoscopic appendectomy, the appendix is ligated and divided within the abdominal cavity. We have performed 423 laparoscopic appendectomies using an extracorporeal technique during the last 8 years. In this technique, the appendix is delivered to the surface through the cannula, and appendectomy is carried out extracorporally. RESULTS AND CONCLUSION: The extracorporeal technique of appendix removal can be performed as safely and efficiently as the open technique. We report our data on the series of 423 operations, in which we had the encouraging experience that the video-assisted extracorporeal technique is a practical and reasonable alternative to the traditional laparoscopic technique.     

Short-wavelength automated perimetry in patients with migraine

Background The aim was to investigate short-wavelength sensitivity deficits in patients with migraine.Methods Fifteen migraine and 18 age-matched healthy volunteers with normal ophthalmologic examination participated in this study. Migraine characteristics were graded by the Migraine Disability Assessment Questionnaire (MIDAS). All participants underwent SWAP (short wavelength amplitude perimetry) testing using a Humphrey field analyzer; there was a 30-2 presentation pattern.Results Short wavelength amplitude perimetry parameters for mean deviation (MD; p<0.0001) and pattern standard deviation (PSD; p<0.0001) were significantly worse in the migraine group. In the migraine group 53.3%. of eyes had glaucoma hemi-field tests (GHT) outside normal limits and 10 of these had early glaucomatous visual field loss. Statistically significant correlations were found between frequency of migraine attacks and MD (p=0.02; r=0.56) and PSD (p=0.03; r=0.41) and also between the MIDAS score and MD (p=0.03; r=0.49) and PSD (p=0.04; r=0.51). In all migraine cases with early glaucomatous visual field defect a corresponding site of the head was predominantly involved in headache (p=0.03).Conclusion Some patients with severe migraine have earlier defects on SWAP suggesting a common vascular insult of glaucoma and migraine, and all migraine cases with high MIDAS scores should be further evaluated for early glaucomatous visual field defects using SWAP.     

Risk factors and infant outcomes associated with umbilical cord prolapse.

OBJECTIVES: Our goal was to identify risk factors associated with umbilical cord prolapse and to review the perinatal outcome of cases of cord prolapse. METHODS: During the study years 77 cases were identified retrospectively. Associations between cord prolapse and potential risk factors were evaluated by means of the odds ratio. RESULTS: Of the 77 fetuses with umbilical cord prolapse 9.1% had a fetal weight of < 2500 gas compared with 9.4% for fetuses in control group (P > 0.05). The umbilical cord prolapse occurred in association with vertex presentation 66 times (85.7%), breech presentation nine times (11.7%) and transverse presentation two times (2.6%). The occurrence of breech presentation among the control cases was 2.6%, and that of transverse lie was 1.7% (P < 0.01). Case mothers were 1.6 times more likely to be multiparas compared with the control group (P < 0.01). The perinatal mortality rate was 39/1000. CONCLUSIONS: Our study showed that abnormal fetal presentation and multiparity are associated with an increased risk of umbilical cord prolapse. The association of risk of cord prolapse with low birth weight was statistically insignificant (P > 0.05). We suggest that the cesarean delivery decreased the risk of perinatal mortality among cases of cord prolapse.
