Treatment of sialorrhea with botulinum toxin A injection in children

Aims

We aimed to evaluate the effectivity and safety of botulinum toxin A (BT-A) to reduce sialorrhea in children with hypersalivation due to neurological diseases.

Methods

Patients who had a complaint of severe sialorrhea were included in the study. Drooling severity of the patients was evaluated using the classification of Thomas-Stonell and Greenberg. The frequency of aspiration before and after the procedure was recorded. The 24-hour saliva amount and mean duration of two consecutive aspirations were recorded. BT-A was injected into the bilateral parotid and submandibular glands by a otorhinolaryngologist under the guidance of ultrasound guidance (USG).

Results

When patients' mean drooling severity scores, drooling frequency scores, mean duration of two consecutive aspirations, and amount of saliva collected before and after procedure were compared, a statistical significance was observed. One-year hospital records before after and injection were examined and it was observed that after BT-A injection, hospital visits were statistically significantly low (P = 0.017).

Conclusion

BT-A injection into salivary glands is well tolerated, is minimally invasive, has low complication rates and should be performed into both parotid and submandibular glands under USG. Although there is still no consensus on the ideal dose and frequency of injections, it is thought that a dose of 1U/kg/gland can be used with safety in pediatric age groups and the dimensions of the salivary glands and quantitative measurements of the amount of saliva should be utilized. Larger studies involving more patients are required in order to constitute a standard injection protocol.

The association between the lymphocyte-to-monocyte ratio and coronary artery disease severity in patients with stable coronary artery disease

OBJECTIVE

Inflammation plays an important role in the pathogenesis of atherosclerosis. The lymphocyte-to-monocyte ratio (LMR) may reflect a systemic inflammatory status. We investigated the association between the LMR and coronary artery disease (CAD) in patients with stable angina pectoris.

PATIENTS AND METHODS

A total of 221 consecutive patients who had been routinely referred for coronary angiography, for stable angina pectoris and 72 patients with normal coronary arteries were included in the present study. We analyzed the relation between the LMR and the angiographic severity of CAD. The SYNTAX score (SxS) was used for assessing the severity of coronary atherosclerosis.

RESULTS

The neutrophil-to-lymphocyte ratio (N/L ratio), platelet size distribution width (PDW), neutrophil and uric acid levels were significantly higher in the stable angina pectoris group than in the control group. The LMR was significantly lower in the stable angina pectoris group than in the control group (4.5±3.2 vs. 6±2.9, p < 0.001). The MPV/L ratios were similar in both groups. Patients with elevated SYNTAX scores (>32) had lower LMR values (3.2±1.5 vs. 4.6±3, p = 0.002). The monocyte count/HDL-C ratio (MHR) was significantly higher in patients with stable CAD than in the control group (0.015±0.008 vs 0.009±0.004, p < 0.001); however, it was similar in the higher SYNTAX score (>32) and lower SYNTAX score groups (0.018±0.007 vs. 0.014±0.008, p = 0.056). Using multivariate logistic regression analysis, we found that only the LMR was an independent predictor of the high SYNTAX scores in patients with stable angina pectoris.

CONCLUSIONS

 The LMR, an inexpensive and easily measurable laboratory variable, is significantly associated with the presence of CAD and high SYNTAX scores in patients with stable angina pectoris.

A randomized study to evaluate post-dural puncture headache after cesarean section: Comparison with median and paramedian approaches

Background

Although the most popular anesthesia technique for cesarean is spinal anesthesia, its most common complication is post-dural puncture headache (PDPH).

Aim

We aimed to determine the effect of median and paramedian approaches during spinal anesthesia on PDPH in patients undergoing cesarean section.

Subjects and Methods

200 pregnant women between the ages of 19-45 years, ASA physical status II, scheduled to undergo elective cesarean section under spinal anesthesia, were studied. The patients were randomized into two groups: Group M; (n = 100) spinal anesthesia with the median approach, Group PM; (n = 100) spinal anesthesia with paramedian approach. The patients were questioned for the possible occurrence of PDPH on the first, third and seventh postoperative days. A telephone follow-up call was used if the hospital stay was shorter than seven days. Post-dural puncture headache was evaluated according to the International Classification of Headache Disorders (ICHD-III) diagnostic criteria. Normally distributed data were summarized using mean and standard deviation. Skewed data were summarized using median (range).

Results

A total of 200 patients completed the study. There were no statistically different between the groups by comparing the incidence and characteristics of PDPH (32% vs. 28%, P = 0.548). Most patients rated their pain intensity during PDPH as mild to moderate in both groups (p = 0.721). PDPH onset time was 2 (1-4) days in Group PM versus 3 (1-7) days in Group M (p = 0.173). No patient needed for epidural blood patch in both groups.

Conclusions

Spinal anesthesia with a median or paramedian approach at cesarean section has no effect on the incidence of PDPH, but we believe that there has been a need for further studies with larger or different patient populations.

Impact of QRS morphology on heart rate turbulence and heart rate variability after cardiac resynchronization therapy in patients with heart failure

OBJECTIVE

Impairment of heart rate turbulence (HRT) and heart rate variability (HRV) are associated with poor prognosis in chronic heart failure (CHF). Although previous studies have demonstrated that patients with a left bundle branch block (LBBB) have a better outcome with cardiac resynchronization therapy (CRT), the effect of QRS morphology on HRV and HRT is not known. We aimed to evaluate the effect of QRS morphology on HRV and HRT after CRT implantation in patients with CHF.

PATIENTS AND METHODS

Patients who had been implanted a CRT device with cardioversion-defibrillation feature were included to the study. Forty-three patients with LBBB (group 1) were compared with 21 patients without LBBB (group 2). HRV and HRT parameters were compared before and one month after CRT implantation.

RESULTS

We compared the echocardiographic and electrocardiographic changes in both groups after CRT. Cardiac output (CO) was found to be significantly much more increased in group 1 (1.1 ± 0.4 vs. 0.6 ± 0.4, p = 0.001). Similarly, except SDNN and LF, all HRT and HRV parameters were significantly changed in the patients with LBBB (TO 1.4 ± 0.3 vs. 1.2 ± 0.2, p = 0.001; TS -1.8 ± 0.7 vs. -0.9 ± 0.7, p = 0.001; RMSSD -15.7 ± 9.9 vs. -6.3 ± 6.2, p = 0.001; PNN50 -7.0 ± 4.6 vs. -1.7 ± 1.1, p = 0.001; HF -13.3 ± 6.7 vs. -4.3 ± 3.5, p = 0.001; LF/HF 1.9 ± 0.4 vs. 1.5 ± 0.2, p = 0.001) compared to those without LBBB. Lineer regression analysis showed that the CO (β = 0.2, t = 2.8, p = 0.007) and QRS configuration (β = 0.6, t = 0.5, p = 0.001) were independent parameters affecting TO.

CONCLUSIONS

HRV and HRT are improved after CRT but these improvements are more remarkable in patients with LBBB. CO, QRS configuration (but not duration) were two independent parameters affecting TO, LF and LF/HF ratio after CRT.

Relationship of apelin, procalcitonin, and fetuin-A concentrations with carotid intima-media thickness in acromegaly

Background

Acromegaly is characterized by excess growth hormone and insulin-like growth factor-1 concentrations. There is conflicting evidence as to whether acromegaly is associated with an increased risk of atherosclerosis. Apelin is an adipose tissue-derived peptide that may be associated with hyperinsulinemia. Fetuin-A is a hepatocyte produced plasma glycoprotein that has an important role as a calcification inhibitor. The aim of this study was to examine apelin, fetuin-A, and procalcitonin concentrations and to assess their relationship with carotid intima medial thickness (cIMT) in subjects with acromegaly.

Methods

Apelin, fetuin-A, and procalcitonin serum concentrations were measured in 37 (20 inactive and 17 active) subjects with acromegaly and 30 control subjects, along with carotid intima medial thickness.

Results

The concentrations of apelin, fetuin-A, and procalcitonin were increased in subjects with acromegaly. There were significant correlations between apelin, fetuin-A, and procalcitonin in subjects with acromegaly. Carotid intima medial thickness values were similar between control subjects and subjects with acromegaly.

Conclusions

Carotid intima medial thickness was not increased in subjects with acromegaly. It is possible that the increased apelin and fetuin-A concentrations observed play a protective role against the development of atherosclerosis in subjects with acromegaly.

Relation with HOMA-IR and thyroid hormones in obese Turkish women with metabolic syndrome

The aim of this study was to investigate the relationship between insulin resistance and thyroid function in obese pre- and postmenopausal women with or without metabolic syndrome (MetS). 141 obese women were divided into two groups, HOMA-IR<2.7 and HOMA-IR>2.7, to evaluate relation with HOMA-IR and fatness, hormone and blood parameters. They were then divided into four groups as pre- and postmenopausal with or without MetS. Various fatness, hormone and blood parameters were examined. Statistically significant difference was found in weight, body mass index (BMI), waist circumference, fat%, fasting insulin, TSH, FT3, FT4, FSH, Anti-microsomal antibody (ANTIM) and triglycerides levels in HOMA-IR<2.7 and HOMA-IR>2.7 obese Turkish women. This study showed that age, weight, BMI, waist circumference, fat%, fasting insulin, FT3, ANTIM, FSH, LH, total cholesterol, triglycerides, HDL, HOMA-IR, systolic and diastolic blood pressure levels were related in preand post menopausal status in obese women with or without MetS. Obesity may influence the levels of thyroid hormones and increases the risk of MetS in women. Postmenopausal status with MetS is associated with an increased TSH, FT3 and FT4 levels and HOMA-IR in obese women. Strong relation was observed with MetS and TSH and FT3 levels.

A prospective, multi-center study: factors related to the management of diabetic foot infections

The Turkish Association of Clinical Microbiology and Infectious Diseases, Diabetic Foot Infections Working Group conducted a prospective study to determine the factors affecting the outcomes of diabetic foot infections. A total of 96 patients were enrolled in the study. Microbiological assessment was performed in 86 patients. A total of 115 causative bacteria were isolated from 71 patients. The most frequently isolated bacterial species was Pseudomonas aeruginosa (n = 21, 18.3%). Among cases with bacterial growth, 37 patients (43%) were infected with 38 (33%) antibiotic-resistant bacteria. The mean (±SD) antibiotics cost was 2,220.42 (±994.59) USD in cases infected with resistant bacteria, while it was 1,206.60 (±1,160.6) USD in patients infected with susceptible bacteria (p < 0.001). According to the logistic regression analysis, the risk factors related to the growth of resistant bacteria were previous amputation (p = 0.018, OR = 7.229) and antibiotics administration within the last 30 days (p = 0.032, OR = 3.796); that related to the development of osteomyelitis was wound size >4.5 cm(2) (p = 0.041, OR = 2.8); and that related to the failure of the treatment was the growth of resistant bacteria (p = 0.016, OR = 5.333). Diabetic foot osteomyelitis is usually a chronic infection and requires surgical therapy. Amputation is the accepted form of treatment for osteomyelitis. Limited limb-saving surgery and prolonged antibiotic therapy directed toward the definitive causative bacteria are most appropriate. This may decrease limb loss through amputations. As a result the infections caused by resistant bacteria may lead to a high cost of antibiotherapy, prolonged hospitalization duration, and failure of the treatment.

Effects of substitutive therapy on right ventricular systolic and diastolic functions in patients with idiopathic hypogonadotropic hypogonadism

BACKGROUND

There have been controversial studies evaluating ventricular functions in patients with idiopathic hypogonadotropic hypogonadism (IHH). A recent study has demonstrated that low serum testosterone levels are associated with increased cardiovascular mortality.

AIM

We aimed to investigate ventricular functions by standard echocardiography and examine the effects of substitutive therapy on right ventricular (RV) functions in patients with IHH by means of pulsed wave tissue Doppler imaging (PWTDI).

METHODS

Twenty-three patients with IHH and 31 controls were evaluated by standard echocardiography and PWTDI. Isovolumic acceleration (IVA), myocardial systolic wave (Sm) velocity, myocardial precontraction time (PCTm), and PCTm to contraction time (CTm) ratio were determined as systolic indices. Myocardial relaxation time (RTm), early (Em) velocity, late (Am) velocity, and Em to Am ratio were determined as diastolic indices.

RESULTS

Peak pulmonary artery pressure (PAP) was significantly higher in control subjects (p=0.008). IVA and Sm values were similar in patients and controls. Em, Am velocities, and their ratios did not differ. PCTm was significantly longer (p=0.001) and PCTm to CTm ratio was significantly higher in patients (p=0.001). These parameters also decreased after replacement therapy, albeit not statistically significantly (p>0.05). PAP was significantly higher after substitutive therapy (p=0.009).

CONCLUSIONS

Ventricular functions are normal in patients with IHH. Substitutive therapy has no effects on RV functions. However, substitutive therapy may increase PAP in small amounts, which has no immediate clinical implication with short-term use.

Impact of Insulin Sensitivity in Relationship with Prolactin and Thyroid Stimulating Hormone

INTRODUCTION

It is well recognized that there is a close relationship between TSH and PRL levels. The aim of this study was to evaluate the impact of insulin sensitivity on the association between TSH and PRL in euthyroid obese subjects.

MATERIAL AND METHODS

Retrospective cross-sectional analysis was carried out on 165 euthyroid obese or overweight female patients. Prolactin, TSH, free thyroxine (FT4), free triiodothyronine (FT3), fasting plasma levels of insulin and glucose, postprandial levels of glucose, homeostasis model assessment (HOMA) for insulin resistance (HOMA-IR) and insulin secretion (HOMA-beta cell), body weight, height, body mass index (BMI) and waist circumference were assessed. Statistical tests used were unpaired Student's t-test adjusted by Bonferroni's method and Pearson correlations with Bonferroni corrections.

RESULTS

There was no significant difference in prolactin levels between insulin sensitive and resistant subjects. Compared to insulin sensitive subjects, TSH levels were higher in insulin resistant subjects but it was not statistically significant. We observed significant positive correlation between prolactin and TSH in insulin sensitive and normoglycemic subjects (r=0.273, p=0.039 and r=0.253, p=0.023, respectively) but this correlation was lost in insulin resistant subjects and subjects who had fasting glucose levels >or=100 mg/dl (r=0.057, p=0.609 and r=0.090, p=0.404, respectively).

CONCLUSIONS

The findings of this study provide some clues about the relationship between PRL and TSH in insulin sensitive obese subjects. The insulin sensitivity and carbohydrate homeostasis seem to be involved in relationship with PRL and TSH by the brain via serotoninergic and dopaminergic system.

Postpartum maternal levels of hemoglobin A1c and cord C-peptide in macrosomic infants of non-diabetic mothers

OBJECTIVE

This study was designed to test the hypothesis that macrosomia in infants born to non-diabetic mothers is associated with an increased incidence of hyperinsulinemia and normal maternal glucose regulation in late pregnancy.

METHODS

Twenty mothers and their macrosomic infants were chosen as the study group, and 20 mothers with their appropriate-for-gestational-age infants were chosen as the control group.

RESULTS

No difference in postpartum mean hemoglobin A1c levels was observed between the mothers of macrosomic infants and those of control infants. Cord plasma C-peptide levels were significantly higher in macrosomic than in control infants.

CONCLUSIONS

This study revealed that macrosomic infants of non-diabetic mothers were significantly more likely to have hyperinsulinemia than were normal-sized infants, and this hyperinsulinemia was not caused by dysregulation in glucose metabolism.

Effects of breathable disposable diapers: reduced prevalence of Candida and common diaper dermatitis

Infants wearing breathable disposable diapers experienced significantly less diaper dermatitis (DD) compared to infants wearing standard, nonbreathable disposable diapers in a series of double-blind clinical trials. Severe DD, including confirmed infection with Candida albicans, was reduced by 38-50% among infants wearing highly breathable (HB) diapers. The prevalence of DD was inversely related to the breathability of the garments. The inhibitory effect of breathable diapers on the survival of Candida was further confirmed in controlled experiments with adult volunteers. A suspension of C. albicans cells was applied to delineated sites on the volar forearm. Each site was then covered by a full-thickness patch from either an HB or a standard diaper. Survival of Candida colonies was reduced by almost two-thirds in the breathable diaper-covered sites compared to the control sites.

Investigation of the relationship between low Apgar scores and early neonatal thyroid function

BACKGROUND

The aim of the present study was to assess the effects of low Apgar scores on perinatal thyroid function.

METHODS

Forty full-term infants delivered by the normal spontaneous vaginal route were enrolled into the study. All babies had 1 and 5 min Apgar scores below 4. The control group consisted of 26 full-term healthy neonates. Cord blood and serum tri-iodothyronine (T3), thyroxine (T4), reverse tri-iodothyronine (rT3), free thyroxine (FT4), thyroid-stimulating hormone (TSH) and thyroid-binding globulin (TBG) determinations were performed by an enzyme immunoassay method.

RESULTS

The mean values of FT4 and T4 observed in the cord blood of the study group were significantly lower compared with matched controls, whereas the mean TSH values were significantly higher. There were no differences in concentrations of T3, rT3 and TBG between the two groups.

CONCLUSIONS

These results demonstrate the existence of transient hypothyroidism at birth in babies with Apgar scores below 4 delivered by the spontaneous vaginal route.

Three-generation reproduction study with dioctyl sodium sulfosuccinate in rats

Groups of 30 male and 30 female rats (F0) were fed diets containing 0, 0.1, 0.5, or 1.0% dioctyl sodium sulfosuccinate (DSS) for 10 and 2 weeks, respectively. The F0 animals were then mated to produce an F1 litter. Groups of 30 male and 30 female F1 animals were fed the same dose levels for at least 10 weeks postweaning, and the breeding program was repeated to produce F2 animals. F3 animals were produced from F2 animals by the same procedure. The study was terminated with the F3 weanlings. Test diets were fed continuously throughout the study. All F0, F1, and F2 adults and F3 weanlings (one/sex/litter) were necropsied and given a macroscopic examination. There were no effects on reproductive function for parental animals of either sex during any of the three generations in this study. At the highest dose level (1.0% DSS), body weights were lower than those of controls during the premating phase for males in all three generations and for F1 and F2 females. Body weights for F1 and F2 males and females in the 0.5% dose group were also low during the premating phase. Pup weights on Lactation Day 0 were significantly lower than those of controls only for the high-dose group during the third generation. However, lower pup weight gains in the mid- and high-dose groups resulted in significantly lower pup weights on Day 21 for all three generations. Perinatal pup survival across three generations ranged from 96 to 100% for the control and treated groups. Pup survival ranged from 95 to 100% for controls, from 98 to 100% for low- and mid-dose groups, and from 91 to 99% for the high-dose group. There were no treatment-related mortality and antemortem or macroscopic observations. In summary, DSS administered in the diet to three successive generations of rats at levels of 0.5 and 1.0% caused a reduction in body weights for parental males in all generations and for F1 and F2 females. Pup weights at the 0.5 and 1.0% dose levels were also lower than those of the control in all three generations. However, the reduced body weights did not interfere with development of normal reproductive performance. DSS at levels up to 1.0% had no effects on the reproductive function of either sex in any generation and produced no treatment-related antemortem or macroscopic observations.
