Prevalence of hepatitis B surface antigen among pregnant women in a low-risk population.

OBJECTIVES: To estimate the prevalence of chronic hepatitis B carriers among our low-risk obstetric population and to determine the need for routine screening. METHODS: A group of 1224 pregnant women, admitted to Gazi University Medical Center, were screened for HBsAg using an enzyme-immunoassay technique, and the obstetrical care records were reviewed. RESULTS: Fifty-three patients were seropositive with a prevalence of 4.33% for HBV chronic carrier status in our obstetric population. CONCLUSIONS: Routine HBsAg screening is advisable in our antenatal population.

Surgical treatment of urinary stress incontinence by a suburethral sling procedure using a Mersilene mesh graft.

A suburethral sling procedure using a Mersilene mesh has been performed in 24 patients. Six patients had recurrent incontinence after an unsuccessful past operation. A postoperative follow-up was done for an average of 24 months. Twenty-three patients were free of symptoms, while only 1 patient had recurrent incontinence. The suburethral sling procedure can be applied to all patients, particularly for recurrent stress urinary incontinence, with reasonable cure rates when performed with a proper technique.

Huge uncal branch of the anterior choroidal artery.

A huge uncal branch of the anterior choroidal artery was found in one of 22 cerebral hemispheres. The uncal artery measured 0.7 mm in diameter. It gave off small branches to the uncus, as well as a large parahippocampal artery, the accessory anterior temporal artery, and the anterior hippocampal artery. This uncal artery supplied, in addition to the uncus, most of the ventromedial surface of the parahippocampal gyrus, part of its dorsal surface, the rostromedial portion of the lateral occipitotemporal gyrus, and the rostral part of the hippocampal formation. Such a huge uncal artery has implications for surgery in the uncohippocampal region.

Microsurgical anatomy of the hippocampal arteries.

An anatomical study of the vascularization of the hippocampus was performed on 30 hemispheres. There were a total of 140 arteries supplying the hippocampi, for an average of 4.7 arteries per hemisphere (range three to seven arteries). Based on the origin and caliber of the arteries supplying the hippocampus, the hemispheres were divided into five groups: A) in 57% of the hemispheres studied, the origin was mixed and included the anterior choroidal artery (AChA), the main trunk of the posterior cerebral artery (PCA), and the inferior temporal, lateral posterior choroidal, and splenial branches of the PCA; B) in 27%, all of the inferior temporal branches of the PCA predominantly supplied the hippocampus; C) in 10%, the anterior inferior temporal branch of the PCA was the predominant supplier: D) in 3%, the hippocampus was predominantly supplied by arteries originating from the main trunk of the PCA (Uchimura artery); and E) in 3%, the AChA gave origin to the hippocampal vessel. It was found as a result of this study that the PCA directly and by its branches contributes much more to the blood supply of the hippocampal formation than the AChA. The uncal sulcus was found to be an important anastomotic site between the hippocampal branches of the AChA and the hippocampal branches of the PCA. In 26.6% of hemispheres, one of the hippocampal arteries arose from the lateral posterior choroidal artery. The splenial artery made a loop close to the extraventricular part of the hippocampal tail and gave off multiple vessels to this structure in 36.6% of hemispheres. The finding that the AChA passes through the choroid fissure as a trunk and its later division into the lateral plexal and medial perforating branches within the choroid plexus may be of surgical significance.

Prevalence of Chlamydia trachomatis infection in the Turkish female population.

Chlamydia trachomatis infection is the most common of the sexually transmitted diseases. In this study of screening for C. trachomatis infection in the Turkish female population, Chlamydia IgG enzyme immunoassay (Ch IgG EIA) was used to detect the exposure to C. trachomatis. Ch IgG EIA was studied in 469 women attending the Gynecology and Obstetrics Clinic of the University of Gazi School of Medicine. Ch IgG EIA was found positive in 35 (7.46%) blood specimens. The highest ratio of seropositivity was detected among the infertile population (11.17%).

[Investigation of pre- and post-treatment cephalometric measurements of the subjects treated by Edgewise technique].

In this study, pre and posttreatment cephalometric measurements of twenty-four cases, of which twelve had Angle Class I and twelve had Angle Class II, division 1 malocclusion were studied. Dental, skeletal and soft tissue changes were observed in both class I and class II, 1 malocclusions treated by Edgewise Technique with extraction.

[Relationships between some cephalometric measurements and the increments in skeletal age, height, and weight in the children aged 10-11 years].

In this study, the heights and weights of 66 children, 34 females and 32 males, aged 10-11 years were measured, and their hand-wrist and cephalometric head radiographs were taken at the interval of one year. Some angular and linear measurements were made and skeletal ages were determined on the first and second films. The differences of the measurements were calculated by subtracting the first year measurements from the second year measurements. The interrelationships between the cephalometric measurement differences and the skeletal age, height, and weight differences were investigated by means of correlation analysis. Furthermore, the correlation coefficients were verified by t test. Most of the correlation coefficients were found to be statistically unsignificant, while a few statistically significant.

[Tracing and measuring errors in the roentgenographic cephalometry].

In the present study, thirty cephalometric films which had been used in three different investigations using almost the same parameters were selected and divided into two groups. Twenty-three parameters in the first group and nine parameters in the second, which were used in two and three investigations respectively, were statistically compared. Paired t test was used in the first group and variance analysis in the second group. In conclusion, a lot of parameters exhibited statistically significant variability, while some of them were not.

Erythromelalgia associated with hypertension and leukocytoclastic vasculitis in a child.

Erythromelalgia is an acrocyanotic rheumatic disease presenting with erythema, and pain and a burning sensation in the hands and feet; it is rarely encountered during childhood. Hot or warm conditions may precipitate pain and erythema in the extremities and the symptoms may regress upon the application of cold water. The disease is usually secondary to other systemic diseases in adults. On the other hand, it is idiopathic in children. This article describes a case of erythromelalgia presenting with leukocytoclastic vasculitis and hypertension in a 7-year-old child who responded to therapy with prednisolone and phenoxybenzamine.
