Repair of nostril stenosis using a triple flap combination: boomerang, nasolabial, and vestibular rotation flaps

Tissue losses within the nose due to various reasons result in the loss of normal anatomy and function. The external nasal valve area is one of the most important functional components of the nose. The columella, lobule, nostril, and alar region are among the components forming the external nasal valve area. Deformities of the nostrils are among the most frequently observed features that interfere with the functional anatomy of the nose. Malformations of the nostrils often emerge subsequent to cleft lip repairs. Stenoses are a common type of pathology among nostril deformities. In cases where a stenosis has formed, breathing problems and developmental anomalies may occur. In the patient with nostril stenosis presented in this report, there was a serious alar collapse and contracture subsequent to a cleft lip repair. In order to repair the nostril stenosis, a "boomerang flap" was chosen. This boomerang flap was used in combination with a nasolabial flap, a vestibular rotation flap, and a conchal cartilage graft to achieve a satisfactory repair.     

Effect of melatonin in the prevention of post-operative adhesion formation in a rat uterine horn adhesion model

BACKGROUND: Our main aim was to investigate the effects of melatonin (ME), possibly the most powerful free-radical scavenger, on the prevention of i.p. adhesion formation in rat uterine horn. Our secondary aim was to determine whether different methods of administration of ME were beneficial. METHODS: Animals were randomly assigned into seven groups, each consisting of 13 rats. Measured serosal injury was created using a standard technique. While control and two sham groups were not given ME, two of the remaining four groups were given a single dose of 10 mg/kg (2 mg) of ME i.p. immediately after injury and 30 min prior to injury respectively. In the two other groups, ME treatment was continued daily for 5 days. All animals were killed 2 weeks after surgery and adhesions were determined and scored by a examiner blinded to the test. RESULTS: The extent, severity and total scores of adhesion were found to be significantly reduced in all of the ME treatment groups when compared with control and sham groups. There were no statistically significant differences between the treatment groups. CONCLUSIONS: This study showed that even single dose ME therapy was effective in the prevention of post- operative i.p. adhesion formation.     

Suicide attempts and risk factors among children and adolescents

The purpose of this study was to determine the prevalence of suicide attempts, and to identify the risk factors for suicide attempts in Turkish children and adolescents between the ages 10 and 20 years. Multi-step, stratified, cluster sampling was used. A stratified sample of 4256 students was selected as representative of the city's school children population. Data was obtained with a pair of structured questionnaires designed to evaluate the presence and risk factors of suicide attempts, both in the children and adolescents and their parents. These questionnaires investigated family environment, subject characteristics, and various risk factors for suicide attempts. Child Beck Depression Inventory (CBDI) was administered to all children and adolescents. After the data quality control process, the study sample was reduced to 4143 children and adolescents. Children and adolescents were divided two groups according to the experience or non-experience of suicide attempts: group 1 (n=80) and group 2 (n=4063), respectively. Three categories of independent variables were assessed: adolescent, family, and socioeconomic characteristics. Logistic regression models were based on the children and adolescents and on parent reports. The prevalence of suicide attempts as reported by the children and adolescents was 1.93% (n=80).The mean age of group 1 was higher than that of group 2 (p=0.002, t=-3.172), as was the mean score of CBDI (p=0.000, t=-9.083). Logistic regression analysis indicated that having problems with parents, using illicit drugs, and psychiatric problems in relatives best predicted suicide attempts in Turkish children and adolescents.     

Computer simulation of trabecular remodeling using a simplified structural model

A simplified three-dimensional simulation of trabecular bone remodeling has been developed. The model utilizes 441 planar structural units to represent approximately 50 mm³ of initial bone volume with 199 basic multicellular units (BMUs). The simulation takes into account trabecular perforation in the structural model. The cases of male bone remodeling with no menopause and female bone remodeling with menopause are examined from the period of simulated age 25–80 years. Menopause is arbitrarily started at age 45 and extends for 7.5 years. Zero-, first-, and second-order BMU activation responses are employed to examine how the bone would be affected by the method of increase of BMU activation during menopause. At age 80, the female bone remodeling simulation produced a bone volume loss of approximately 49% for all three activation responses. This compared to a 38% bone volume loss for the case of no menopause. For the menopause simulations, an average of about 40% of the total bone loss was due to perforation.     

Risk factors for depression in the first postnatal year

BACKGROUND: The aim of the study was to identify risk factors for depression and to estimate its prevalence in postnatal mothers. METHODS: This cross-sectional and multi-centre study was carried out on 1,350 Turkish women in their first postnatal year. Measures included a structured questionnaire and the Turkish version of the Edinburgh Postnatal Depression Scale (EPDS). RESULTS: Of the women, 31.1% had a score of 13 or higher on the EPDS. The mean score and standard deviation was 9.8+/-5.7. In the multivariate analysis, EPDS scores were significantly associated with economic status, access to support from family members and close friends, emotional distress at the pregnancy, whether the pregnancy was planned, health problems during pregnancy, the perceived standard of baby care after delivery, and mental disorder before and during pregnancy. CONCLUSION: The prevalence of EPDS-based depression among Turkish women in postnatal the period was high, and was associated with several social, economic and demographical factors.     

Acute pulmonary edema in a newborn with infracardiac type total anomalous pulmonary venous return and surgical repair

Total anomalous pulmonary venous return (TAPVR) is a rare congenital pathology. Early diagnosis and urgent surgery are life-saving, especially in newborns with pulmonary venous obstruction, which is most commonly seen with infracardiac type. A three-day-old baby boy presented to another clinic with tachypnea and cyanosis. Initial work-up aimed at ruling out persistant pulmonary hypertension, respiratory distress syndrome and pneumonia. Acute pulmonary edema then developed, and on echocardiography obstructive type infracardiac TAPVR was suspected. Cardiac catheterization was done for definitive diagnosis. Urgent surgery was undertaken and pulmonary veins were anastomozed to left atrium with posterior approach. Patient was extubated at 10th day and discharged after three weeks. During one-year follow-up the patient was free of symptoms. Infracardiac type TAPVR is a rare pathology in which early diagnosis and urgent surgery with special postoperative case are mandatory for survival.
