Over restrictive elimination of foods in children with food allergy.

BACKGROUND: Previous studies demonstrated critical deficits in diagnosis and management of childhood food allergy (FA), and recent developments in FA research support adopting a proactive approach in FA management. Our objective was to describe FA knowledge and management patterns of pediatricians. METHOD: We applied a 24-item survey to 170 general pediatricians, pediatric allergists and pediatric gastroenterologists practicing in Turkey. RESULTS: Some IgE-mediated symptoms of FA such as cough, urticaria, wheezing and anaphylaxis were falsely recognized as symptoms of non-IgE-mediated FA by 30%, 29%, 25% and 19% of the participants, respectively. By contrast, 50% of the participants falsely recognized bloody stool, a finding of IgE-mediated FA. Most frequently and least frequently used diagnostic tools were specific IgE (30.5%) and oral food challenge test (1.7%), respectively. Maternal diet restrictions and infant diet restrictions were advised by 82% and 82%, respectively. Percentages of physicians eliminating only 1 food were 21%, 19%; 2 foods were 15%, 11%; 3 foods were 7%, 8%; 4-5 foods were 8%, 11%; 5 to 10 foods were 21%, 26%; and > 10 foods were 28%, 25% from the maternal and infant diet, respectively. Cow`s milk, cheese, butter, yoghurt, baked milk products and hen`s egg were the most commonly restricted items. CONCLUSION: Overall, FA knowledge of pediatricians was fair. Pediatricians utilize an overly restrictive approach when advising diet eliminations in FA. Recent developments favor a more proactive approach to induce immune tolerance and need to be encouraged in pediatric clinical practice. Future educational efforts should focus on emphasizing the deleterious effects of injudicious and extensive eliminations.

A novel autologous dermal filler based on cultured fibroblasts and plasma gel for facial wrinkles: Long term results.

Autologous cultured fibroblasts combined with plasma gel (FibrogelTM) can be used as an injectable autologous soft tissue filler. Herein, we report the assessment of the long-term clinical efficacy and safety of Fibrogel for facial wrinkles. Ten healthy adults were treated for facial wrinkles with Fibrogel, an innovative autologous filler. Patients underwent three treatment sessions at 1-month intervals for the correction of infraorbital, nasolabial, and marionette folds. In each session, 6-8 mL of Fibrogel filler containing 4 million fibroblasts/mL, was injected into the deep dermis or subdermal plane. Three evaluators independently assessed the efficacy at 3, 6 and 12 months after the last treatment, using the validated Global Esthetic Improvement Scale at two different times in a blinded manner. Infraorbital area and lower face were evaluated separately. All patients showed immediate improvement after the first injection at the infraorbital area and lower face. Follow-ups at 3, 6 and 12 months revealed that the improvement was persistent. Adverse reactions were mild and the treatment was well tolerated. Delivering autologous cultured fibroblasts embedded in an autologous plasma gel (Fibrogel) to the skin can provide immediate volume effect and long-term improvement. Therefore, Fibrogel can be considered as a promising novel autologous filler.

Skin manifestations of COVID-19 in children: Part 3.

The current COVID-19 pandemic is caused by the SARS-CoV-2 coronavirus. The initial recognized symptoms were respiratory, sometimes culminating in severe respiratory distress requiring ventilation, and causing death in a percentage of those infected. As time has passed, other symptoms have been recognized. The initial reports of cutaneous manifestations were from Italian dermatologists, probably because Italy was the first European country to be heavily affected by the pandemic. The overall clinical presentation, course and outcome of SARS-CoV-2 infection in children differ from those in adults as do the cutaneous manifestations of childhood. In this review, we summarize the current knowledge on the cutaneous manifestations of COVID-19 in children after thorough and critical review of articles published in the literature and from the personal experience of a large panel of paediatric dermatologists in Europe. In Part 1, we discuss one of the first and most widespread cutaneous manifestations of COVID-19, chilblain-like lesions, and in Part 2 we expanded to other manifestations, including erythema multiforme, urticaria and Kawasaki disease-like inflammatory multisystemic syndrome. In this part of the review, we discuss the histological findings of COVID-19 manifestations, and the testing and management of infected children for both COVID-19 and any other pre-existing conditions.

Comparison of the effects of bispectral index-controlled use of remifentanil on propofol consumption and patient comfort in patients undergoing colonoscopy.

BACKGROUND AND STUDY AIMS: In endoscopic procedures, propofol can be safely administered either alone or in conjunction with remifentanil. The aim of the study is to compare the effects of the administration of propofol alone and the administration of remifentanil in addition to propofol on patient and endoscopist satisfaction, preoperative hemodynamic response, and propofol consumption. MATERIALS AND METHODS: A totally 60 patients were enrolled in the study. Propofol group (Group 1): A 0.4-mg/kg propofol bolus and 1 mg/kg/h maintenance infusion of propofol until a bispectral Index value of 70-75 was achieved. Propofol + remifentanil group (Group 2) received a 0.4 mg/kg propofol bolus dose and maintained with a 0.5 mg/kg/h infusion of propofol + 0.2 mcg/kg/min infusion of remifentanil. The infusion dose of remifentanil was maintained, and the propofol infusion dose was titrated until a BIS value of 70-75 was achieved. RESULTS: In Group 1 (colonoscopic intervention 1 and 5 min) and Group 2 (colonoscopic intervention 10 min.), main blood pressure (MBP) value has a significant decrease. Hypotension occurred in 6 patients in group 1, while 12 patients in group 2. No significant difference was found between the Patient's endoscopist' satisfaction, MBP and heart rate. Propofol consumption was greater in group 1 than in group 2. When the Ramsay sedation levels of Group 1 and Group 2 were compared, a statistically significant difference was observed. CONCLUSIONS: The addition of remifentanil to propofol may be an alternative to the use of alone propofol for sedation in colonoscopic interventions.

Infantile granular parakeratosis: cytologic examination of superficial scrapings as an aid to diagnosis.

Granular parakeratosis (GP) is a benign disorder of keratinization presenting with unilateral or bilateral red to brown hyperkeratotic plaques and papules at the intertriginous areas. The first pediatric case of GP was reported in 2002, and only a few cases have been reported since. Although the exact etiology of GP is unknown, it is thought that certain environmental factors compromise the epidermal barrier and lead to proliferation and altered maturation of the epidermis in predisposed individuals. The histopathology is diagnostic and reveals parakeratosis together with retention of keratohyalin granules within a disproportionately thickened stratum corneum and usually the preservation of stratum granulosum. Herein we report seven cases of infantile GP, six of which also had atopic dermatitis. Cytologic examination confirmed our clinical diagnosis by demonstrating the retention of keratohyalin granules and preservation of the nuclei from the superficial scrapings of the lesions, which we propose as a novel diagnostic technique. In all seven cases the lesions developed after the overuse of topical products and resolved with avoidance of their excessive use. We propose that atopic skin may be more prone to develop GP because the epidermal barrier is disrupted, resulting in the enhanced transepidermal penetration of topical products. In conclusion, GP should be included in the differential diagnosis of diaper area eruptions, especially in atopic children. Cytologic examination of superficial scrapings of the lesions can easily confirm the diagnosis of GP.

A comparison of the effects of lidocaine or magnesium sulfate on hemodynamic response and QT dispersion related with intubation in patients with hypertension.

BACKGROUND: The aim of this study was to investigate the effect of magnesium administered before induction on the hemodynamic response and QT dispersion (QTd) related with intubation in hypertensive patients and to compare it with lidocaine. METHODS: Patients with essential hypertension who were under ≤ 65 years old, scheduled for elective surgery with a Mallampati score of I-II were included in the study. Patients were randomly divided into three groups; group M (n = 20) received magnesium sulfate, group L was prescribed lidocaine, and group C (control group) received saline. Standard 12-lead ECG readings were taken before the induction of anesthesia and at the first and fifth minutes following intubation. RESULTS: There were no statistically significant differences between the groups in terms of age, sex and demographic characteristics. There was no significant difference in the QT interval values before induction and 5 minutes after intubation in all groups. In group M, QTd values were significantly lower at the first and fifth minutes than before induction. There were no statistically significant differences in QTd values at different times in group L and group C. CONCLUSION: QTd is not increased during tracheal intubation in hypertensive patients so there is no need for magnesium sulfate for these patients. But as QTd has been shown to increase during tracheal intubation for coronary artery disease patients, magnesium sulfate might be useful for those patients although future studies are required to confirm this statement.

Neck Rejuvenation with Fractional CO2 Laser: Long-term Results.

OBJECTIVE: To assess the effectiveness of 10,600nm fractional CO2 laser for neck aging at one month and one year after treatment. Design/Setting/Participants/Measurement: Twenty patients underwent 10,600nm fractional CO2 laser treatment over the entire neck. Clinical features of the patients were classified according to Baker classification. The degrees of skin laxity, jowling, fat deposition, and horizontal neck lines were evaluated using a 9-point scale, prior to treatment at one month and one year after the treatment. The patients were independently assessed by the authors at two different times in a blinded fashion. RESULTS: Skin laxity, jowling, fat deposition, and horizontal neck lines scores were significantly lower than the baseline values at one month and one year. One-year follow-up values of the same parameters were still significantly lower than the baseline. No persistent complication developed after treatment. CONCLUSION: The results of this study confirm that fractional CO2 neck rejuvenation is an effective treatment option with long-term efficacy for patients who mainly have skin laxity and jowling together with skin surface pigmentation.

Refractory Postinflammatory Hyperpigmentation Treated Fractional CO2 Laser.

OBJECTIVE: Postinflammatory hyperpigmentation is a reactive hypermelanosis of the skin that occurs as a consequence of an inflammatory process, such as acne, eczema, drug reactions, burns, chemical peelings, and laser applications. Although topical agents remain to be the first-line treatment of postinflammatory hyperpigmentation, treatment of recalcitrant cases is challenging. The Q-switched ruby laser, the low-dose Q-switched neodymium-doped yttrium aluminum garnet laser, and the fractional 1550nm erbium-doped fiber laser have been reported to improve postinflammatory hyperpigmentation. DESIGN/SETTING/PARTICIPANTS: The authors present a case of refractory postinflammatory hyperpigmentation successfully treated with two sessions of fractional CO2 laser in a 24-year-old woman with Fitzpatrick skin type III. RESULTS: After two treatment sessions with a one-month interval, the lesion totally cleared without any complications. CONCLUSION: Although many laser systems, including fractional CO2 lasers, can cause postinflammatory hyperpigmentation, they also can be very efficacious tools by using conservative laser settings and by providing appropriate post-treatment care in recalcitrant postinflammatory hyperpigmentation treatment.

Dexamethasone added to levobupivacaine in ultrasound-guided tranversus abdominis plain block increased the duration of postoperative analgesia after caesarean section: a randomized, double blind, controlled trial.

OBJECTIVES: When added to local anaesthetics, dexamethasone can prolong the duration of peripheral blocks. Dexamethasone has a long and efficient glucocorticoid structure and presents anti-inflammatory properties. The aim of this study was to determine the effect of dexamethasone on the block duration added to levobupivacaine used for transversus abdominis block (TAP) applied to patients who underwent caesarean section. PATIENTS AND METHODS: Forty-two patients with spinal anaesthesia in an American Society of Anesthesiologists (ASA) I-II risk group were included in the study and divided into two groups. Bilateral 30 ml 0.25% levobupivacaine and 2 ml 0.9% NaCl for the levobupivacaine group and bilateral 30 ml 0.25% levobupivacaine and 2 ml dexamethasone (8 mg) for the dexamethasone group were administered in a TAP block performed with ultrasonography. The time need for the first analgesic in the postoperative period was recorded. The numeric evaluation scale, and the total additional analgesic amounts were recorded. RESULTS: The time before the administration of the first additional analgesic dose was prolonged significantly in the dexamethasone group compared to the levobupivacaine group (p = 0.004). The pain scores were lower in the dexamethasone group for superficial pain. A significant difference for the dexamethasone group was observed in the evaluation of deep pain. The total consumption of tramadol was significantly lower in the dexamethasone group (p = 0.001). CONCLUSIONS: The utilization of dexamethasone, which has a prolonging effect on the transversus abdominis plane block, may be an alternative to epidural opioid analgesia in caesarean section. We observed that dexamethasone added to levobupivacaine in a TAP block applied for analgesia following a caesarean section procedure prolonged the time required for analgesia.

Antiemetic effects of dexamethasone and ondansetron combination during cesarean sections under spinal anaesthesia.

BACKGROUND: Nausea and vomiting are frequently seen in patients undergoing cesarean section (CS) under regional anesthesia. We aimed to compare the antiemetic efficacy of ondansetron and dexamethasone combination with that of the use of each agent alone to decrease the incidence of post-delivery intraoperative nausea and vomiting (IONV) during CS under spinal anesthesia. OBJECTIVE: To compare the antiemetic efficacy of ondansetron and dexamethasone combination with that of the single use of each agent to decrease the incidence of postdelivery IONV during CS under spinal anesthesia. METHODS: A randomized, prospective, double blind study was performed on 90 patients undergoing planned CS under spinal anesthesia. Patients received 4mg ondansetron in Group O, 8mg dexamethasone in GroupD, 4mg ondansetron+8mg dexamethasone in Group OD intravenously within 1-2 minutes after the umbilical cord was clamped. Frequency of postdelivery IONV episodes was recorded. RESULTS: A total of 86 eligible patients were included in the study. There were 29 patients in Group O, 29 patients in Group D and 28 patients in Group OD. There were no statistically significant difference between the groups in terms of baseline characteristics and intraoperative managements. Frequency of intraoperative nausea, retching and vomiting experiences were similar between the groups (p>0.05). CONCLUSION: Single dose 4mg ondansetron, 8mg dexamethasone, or combined use of 8mg dexamethasone+4mg ondansetron, given intravenously is all effective agents for the control of postdelivery IONV. Combined use of dexamethasone and ondansetron for the same indication does not seem to increase the antiemetic efficacy.

Evaluation of the olfactory memory after spinal anesthesia: a pilot study.

BACKGROUND: The aim of this study was to investigate the effect of spinal anesthesia (SA) on olfactory memory using Brief-Smell Identification TestTM (B-SIT). PATIENTS AND METHODS: This, prospective, clinical study was performed on 40 ASA physical status I-III patients, between 18-65 years of age undergoing a planned elective minor surgery under SA. All participants were preoperatively informed about B-SIT and the mode of application of the test according to the information in the book. B-SIT was applied to each patient preoperatively and the scores were recorded. B-SIT was reapplied to all patients on the 1st and 2nd postoperative days and the scores were recorded. Moreover, development of postdural puncture headache (PDPH) and/or neurological symptoms (such as hearing loss, diplopia) were checked. RESULTS: Postoperative headache was observed in 7 of the participants and 3 of them was diagnosed to have PDPH. No statistically significant difference was observed in the olfactory memory evaluation of the patients suffering from headache and the 3 patients diagnosed with PDPH. No statistically significant difference was observed in the correct odor answer ratio between the preoperative and postoperative 1st and 2nd days (p > 0.05). CONCLUSIONS: We confirm that SA does not affect olfactory memory. Further studies are necessary to confirm the results of our pilot study in a larger sample.

Treatment of nail psoriasis: common concepts and new trends.

The lifetime incidence of nail involvement in psoriatic patients is estimated to be 80-90%, and the nails can be affected in 10% to 55% of psoriatic patients. Psoriasis may also solely involve the nails, without any other skin findings, in which the treatment can be more challenging. Nail psoriasis may lead to considerable impairment in quality of life due to aesthetic concerns and more importantly limitations in daily activities resulting from the associated pain, which may be overlooked by the physicians. Several topical and systemic treatment modalities, as well as radiation and light systems, have been used in the treatment of nail psoriasis. In the last decade, the introduction of biologic agents and the utilization of laser systems have brought a new insight into the treatment of nail psoriasis. This paper focuses on the recent advances, as well as the conventional methods, in treating nail psoriasis in adults and children, in reference to an extensive literature search.

The prolonged effect of pneumoperitoneum on cardiac autonomic functions during laparoscopic surgery; are we aware?

BACKGROUND: The gynecological laparoscopic surgery requires pneumoperitoneum (PP) with CO2 gas insufflation. CO2 PP may influence cardiac automic function (CAF). This study was conducted to assess its significance and the prolonged effects of CO2 PP on the activity of the cardiac autonomic function 24 hours after the operation by heart rate turbulence (HRT) and heart rate variability (HRV), first time in the literature. PATIENTS AND METHODS: Fifty patients scheduled for elective gynecologic laparoscopy were evaluated. The patients had no preexisting lung or heart disease or pathologic lung function. Conventional general anesthesia with midazolam, propofol, fentanyl, rocuronium, and sevoflurane was administered. ECG recordings were carried out between before 4 h from surgery and the beginning of anesthesia (T1), induction of PP and CO2 evacuation (T2) and a 24-h period postoperatively (T3). The Holter recordings of all patients were analyzed by HRT and HRV. RESULTS: There were significant reductions in in HRV and HRT parameters peri-op period compared to the pre-op values (p < 0.05). In the first 3 h of post-op period, were calculated all HRT and some HRV (SDNN, LF) parameters were also found to be significantly reduced than the values of pre-op period (p < 0.05). CONCLUSIONS: This study described adverse effects of CO2 PP on cardiac autonomic regulation in the early postoperative period according to the long-term HRV and HRT frequency analysis, for the first time in the literature. The early postoperative monitorization may supply efficacious information for arrhythmic complications.

Magnetic resonance imaging contrast agent related pulmonary edema: a case report.

Gadobutrol is a contrast agent often used during magnetic resonance imaging (MRI). The agent has several side effects, some of which can be serious. It has extremely rare life-threatening systemic complications, which can lead to bronchospasm, hypersensitivity reactions and cardiovascular arrest. However, there is no data available on the development of noncardiogenic pulmonary edema following use of gadobutrol. This paper examines the case of a 37-year-old male patient reported to have developed noncardiogenic pulmonary edema after intravenous injection of gadobutrol during MRI.

The attitudes of surgeons concerning preoperative smoking cessation: a questionnaire study*.

BACKGROUND: The purpose of this study was to evaluate the attitudes and behavior of surgeons regarding preoperative smoking cessation. METHODS: A total of 109 anonymous questionnaires were distributed to non-vascular surgeons in our hospital, inquiring about their smoking attitudes, their smoking cessation advice practices, whether they appreciated the benefits of preoperative smoking cessation, and their knowledge of smoking cessation methods. RESULTS: Eighty questionnaires (from 51 resident doctors and 29 academic staff) were returned (response rate: 73.40%). Of the surgeons, 17.50% were current smokers. Although 40% of the surgeons surveyed believed that preoperative smoking cessation reduces postoperative complications, 31.2% of the surgeons (25/63) had given smoking cessation advice at least to 1 patient in the last month. Most of the resident doctors (39.2%) advised smoking cessation within a month; prior to surgery however, the academic staff (27.6%) advised cessation immediately before the operation (p=0.038). There was a significant difference between academic sfaff and resident doctors concerning the method to increase a patient's chance of quitting (p=0.045), even among current smokers (p=0.049). CONCLUSION: The surgeons who participated in the questionnaire were aware that smoking cessation improves outcome, but most of them did not appreciate that providing brief advice, referring to cessation services, or prescribing nicotine replacement therapy (NRT) may be of benefit in helping patients to quit. It is necessary to educate surgeons about the scale of the benefit and the efficacy of smoking cessation interventions or to set up systematic frameworks to offer smoking cessation advice to preoperative patients who smoke.

Melatonin levels and enzymatic antioxidant defense system decrease in blood of patients with bronchial asthma.

The etiology of bronchial asthma (BA) is not clearly understood. In recent years, a few studies have investigated the possible role of reactive oxygen species (ROS) in the etiology of BA. There are some defense mechanisms in the organism to avoid the harmful effects of ROS. Melatonin (MEL) is synthesized by the pineal gland at night and exhibits antioxidant properties. The aim of this study was to investigate serum MEL levels, erythrocyte antioxidant enzyme activities, namely superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and the association of the respiratory function tests, namely dynamic lung volumes; the forced vital capacity (FVC/L, FVC%), the forced expiratory volume in 1 s (FEV(1)/L, FEV(1)%), and peak expiratory flow (PEF/L/s, PEF%) in 30 patients with BA and 30 age-matched healthy controls. The levels of serum MEL, the activities of erythrocyte SOD, and the values of FVC/L, FVC%, FEV(1)/L, and FEV(1)% were significantly lower in the patients with BA than in control group. The positive correlations were observed between FVC% with erythrocyte SOD and GSH-Px, FEV(1)/L as well as FEV(1)% with erythrocyte SOD, whereas negative correlation was observed between PEF/L/s with levels of serum MEL. In conclusion, these results provide some evidence for a potential role of decreased antioxidant enzymes, MEL, and respiratory function test values in BA.
