Sensory processing patterns affect headache severity among adolescents with migraine.

OBJECTIVE: To evaluate the relationship between pain catastrophizing level, sensory processing patterns, and headache severity among adolescents with episodic migraine. BACKGROUND: Catastrophizing about pain is a critical variable in how we understand adjustment to pain and has a unique contribution in predicting pain intensity. Recent reports found that migraine is also related to enhanced sensory sensitivity. However, the relationship between pain severity, pain catastrophizing level and sensory sensitivity requires greater study especially among adolescents. METHODS: Participants were 92 adolescents aged 13-18 years, 40 with episodic migraine and 52 healthy controls. The migraine patients were prospectively recruited from outpatient pediatric neurology clinics. All participants completed the Adolescent/Adult Sensory Profile (AASP), and the Pain Catastrophizing Scale for children (PCS-ch). The migraine groups also completed the PedMIDAS, which measures Headache related disability. RESULTS: Adolescents with migraine had significantly lower tendency to seek sensory input than healthy controls. Elevated rumination and helplessness correlated with higher migraine pain severity. Tendency to avoid sensory input predicted the migraine related disability level. They also significantly higher pain catastrophizing level than healthy controls, as seen in enhanced rumination (p ≤ 0.001) and helplessness (p ≤ 0.05). CONCLUSIONS: Sensory processing difficulties are common among adolescents with episodic migraine. Sensory avoidance may be related to pain experience, and pain catastrophizing and disability level.

Primary Coenzyme Q deficiency Due to Novel ADCK3 Variants, Studies in Fibroblasts and Review of Literature.

Primary deficiency of coenzyme Q10 (CoQ10 ubiquinone), is classified as a mitochondrial respiratory chain disorder with phenotypic variability. The clinical manifestation may involve one or multiple tissue with variable severity and presentation may range from infancy to late onset. ADCK3 gene mutations are responsible for the most frequent form of hereditary CoQ10 deficiency (Q10 deficiency-4 OMIM #612016) which is mainly associated with autosomal recessive spinocerebellar ataxia (ARCA2, SCAR9). Here we provide the clinical, biochemical and genetic investigation for unrelated three nuclear families presenting an autosomal form of Spino-Cerebellar Ataxia due to novel mutations in the ADCK3 gene. Using next generation sequence technology we identified a homozygous Gln343Ter mutation in one family with severe, early onset of the disease and compound heterozygous mutations of Gln343Ter and Ser608Phe in two other families with variable manifestations. Biochemical investigation in fibroblasts showed decreased activity of the CoQ dependent mitochondrial respiratory chain enzyme succinate cytochrome c reductase (complex II + III). Exogenous CoQ slightly improved enzymatic activity, ATP production and decreased oxygen free radicals in some of the patient's cells. Our results are presented in comparison to previously reported mutations and expanding the clinical, molecular and biochemical spectrum of ADCK3 related CoQ10 deficiencies.

Migraine and Tension-Type Headache Among Children and Adolescents: Application of International Headache Society Criteria in a Clinical Setting.

INTRODUCTION: The International Headache Society criteria were written in order to help physicians establish a headache diagnosis. However, sometimes children with headache do not seem to fit any diagnosis. The purpose of our study was to assess the application of the criteria in a clinical setting. METHODS: Medical records of children referred for primary headache to the pediatric neurology clinic at Bnai Zion Medical Center from 2008 to 2017 were assessed. RESULTS: A total of 989 patients (range 6-18 years; 53% female) were assessed at our neurology clinic. Twenty-four percent (n = 241) were diagnosed with tension-type headache, 26% (n = 256) with migraine, and 4.5% (45) with mixed headache. In 41.5% (410), we were unable to reach a specific diagnosis. No differences in gender or age were found between the groups. Children in the migraine group used more analgesic treatments to stop the headache attacks compared with the tension-type headache group (50% vs 38%, P = .001). Patients diagnosed with tension-type headache reported having more emotional difficulties (P = .001). No significant differences were found in headache characteristics (ie, location, sidedness, character), frequency, or intensity between the younger children (ages 6-11) and the adolescents (ages 12-18) within either the tension-type headache or migraine groups. CONCLUSIONS: Retrospective application of International Headache Society criteria in a large cohort of children with headaches failed to diagnose a specific type of headache in 41.5% of children. Migraine and tension-type headache were equally prevalent, and both constituted a major burden on our patients' everyday lives. We found no major differences in frequency, intensity, and characteristics of pain between younger children and adolescents.

Does Herpes 6 Infection Have a Role in Bell's Palsy Among Children and Adolescents?

BACKGROUND: Bell's palsy is a peripheral paralysis of the seventh cranial nerve, whose etiology is unknown. Using polymerase chain reaction technology, it is possible to sample accessible body fluids and identify possible viral factors. The purpose of this research is to investigate its connection to the herpes virus family by testing for the presence of the virus in the saliva and tear fluid of Bell's palsy patients. METHODS: Saliva and tears were collected from 42 children and adolescents suffering from idiopathic facial nerve paralysis. Polymerase chain reaction was used to test for the presence of the viruses Epstein-Barr virus, cytomegalovirus, herpes simplex virus 1 and 2, varicella zoster virus and human herpes virus 6 (HHV-6). Samples were also taken from a control group without paralysis. A second specimen was taken from patients who tested positive for HHV-6 several months after their recovery. RESULTS: Of the 42 patients in the study group, 71% (30 patients) tested positive for HHV-6, compared with only 37% of the control group (P = 0.001). The prevalence of the other 5 viruses tested was low-herpes simplex virus 1: 9.5%, Epstein-Barr virus: 9.5%, cytomegalovirus: 4.8%, varicella zoster virus: 2.3% and herpes simplex virus 2: 0%. Twenty-four of the 30 patients who were HHV-6-positive during their illness were reexamined following recovery. Only 13 patients (54.2%) excreted the virus after recovery from the paralysis. CONCLUSIONS: Herpes 6 virus appears to play some role in the etiology of facial nerve paralysis. The virus was detected in the saliva of children during acute illness and decreased with resolution. Our research opens new insights linking HHV-6 to the etiology of Bell's palsy in children.

Sensory Processing Difficulties Correlate With Disease Severity and Quality of Life Among Children With Migraine.

Introduction: Headaches are common among children and about 80% of children reporting them. Migraine and tension type headaches are the most common primary headaches in children and the prevalence of migraine is about 8%. Accompanying sensory symptoms are common before, during and after migraine attacks. They may be a part of a wider symptom constellation called sensory processing disorder or difficulties (SPD). This includes both hyper or hypo sensitivity to sensations. However, the literature regarding sensory processing symptoms of children and youth with headaches as well as its interaction with child's emotional aspects and quality of life is scarce. Materials and Methods: One hundred and thirty-four children between the ages of 8 and 12 participated in this study. Fifty-four children (22 boys and 32 girls) with episodic migraine were prospectively recruited from pediatric neurological clinics during the years 2014-2017. The control group included 80 healthy children. Both groups completed a health and demographic questionnaire, headache assessment including Ped-MIDAS, Short Sensory Profile, State-Trait Anxiety Inventory (STAI) for children, and the Pediatric Quality of Life Inventory. Results: Children with migraine showed significantly higher prevalence of sensory processing difficulties and lower quality of life compared to healthy controls. Among children with migraine, sensory processing difficulties significantly correlated with lower quality of life. Headache-related disability and sensory processing difficulties predicted quality of life. Conclusion: The possible relationship between migraine and sensory processing disorder or difficulties stresses the need to screen for sensory processing difficulties among children with migraine and when found-refer to their impacts on children's daily function and quality of life.

The role of cellular phone usage by parents in the increase in ASD occurrence: A hypothetical framework.

Over the last few decades there has been a significant worldwide increase in the diagnosis of autism spectrum disorder (ASD), the causes of which are unknown. The biggest environmental change over this decade has been the massive introduction of cellphones. Eye contact is fundamental for infants' development, and parent-infant eye contact is impaired when parents are pre occupied by cellphones. We speculate that children with a pre-existing vulnerability to autism may be adversely affected by this pattern of parental behavior. As a first step toward exploring our hypothesis, we wished to document the extent of cellular phone usage by parents during their child's diagnostic developmental assessment. We speculated that, if under these stressful circumstances of awaiting their child's crucial assessment the parent is not fully engaged with his/her child, then in real daily activities this phenomenon is likely much more pronounced. Of 111 developmental sessions, 73 parents (66%) engaged their phone during the assessment, between 1 and 20 times. Of 62 observations in the waiting room, 52 (83.9%) parents used their phone, 1-19 times. Nine parents (17.3%) used their phone for 10-50% of the time and 16 (30.8%) for more than 50% of the time in the waiting room. In our analysis, the rate of language/motor delays was twice more common among children of cell phone users than among non users (p = 0.04) as an initial support of our hypothesis. Parents' focus and full attention toward their cellphones can adversely affect the development of joint attention in infants and may contribute to the development of autistic features among a vulnerable subgroup of infants. While more research is needed to prove causation, it would be reasonable to advise parents to decrease to minimum the usage of cellphones when interacting with their young children.

Occipital Headaches in Children: Are They a Red Flag?

Occipital headache is considered a risk factor for serious secondary headache pathology. The purpose of our study was to assess the etiology of occipital headaches among children visiting the emergency department. Subjects were children aged 5 to 18 years who were referred to the emergency department due to headaches during the years 2013 to 2014. A total of 314 patients with headaches were seen at our emergency department. Thirty-nine patients had occipital headaches. Viral infections were the most prevalent final diagnosis (97; 31%), followed by migraine (37; 11.8%). None of our patients had a brain tumor. There was no difference in final diagnosis between the occipital and nonoccipital groups. The most common causes of occipital headaches are viral infections and primary headaches. Serious intracranial disorders presenting solely as occipital headaches and not accompanied by other neurologic signs are uncommon. Thus, occipital headaches should be evaluated in the same manner as other headache locations.

Postmastectomy electron-beam chest-wall irradiation in women with breast cancer.

PURPOSE: This retrospective study evaluates the results of postmastectomy electron-beam chest-wall irradiation in patients with breast cancer. METHODS AND MATERIALS: From 1980 to 1994, 144 women with localized breast cancer received postmastectomy radiotherapy. The chest wall was irradiated by electron beam, 6 to 12 MeV energy, depending on wall thickness, 2.0 Gy daily, 5 times/week for total dose of 50 Gy. Forty-one patients received 16-Gy boosts to the mastectomy scar. In addition, the supraclavicular and axilla areas were irradiated by anterior field with 6-MV photon beam. RESULTS: Median follow-up was 84 months. Fifteen patients (10%) had local-regional recurrence (LRR) and 57 patients (40%) had systemic relapse (SR). Median time from mastectomy to LRR was 20 months and median time to SR was 33 months. Axillary lymph nodes status influenced both LRR and SR. LRR rate was 0% in N0 and 12% in N1 disease; SR rate was 14% in N0 and 45% in N1 disease. Disease-free and overall survival was 58% and 67% in 10 years and 50% and 55% in 20 years, respectively. No cardiac toxicity was related to left chest-wall irradiation. CONCLUSION: Postmastectomy electron-beam chest-wall irradiation is as effective as photon-beam irradiation in breast cancer.

[Primary well-differentiated papillary mesothelioma of the peritoneum--a rare but important differential diagnosis].

The primary well-differentiated papillary mesothelioma of the peritoneum is a rare neoplasm, characterized by an indolent course and good prognosis. We report the case of a 55-year-old male, who presented progressive abdominal swelling due to ascites. On computerized tomography, the peritoneum was diffusely thickened and irregular. Cytologic examination showed a lymphocyte rich ascitic fluid. Malignant cells could not be identified. On laparoscopy, numerous nodular lesions were observed on the peritoneal surface. A biopsy of the latter showed an unusual malignant growth. Using immunohisto-chemistry and electron microscopy, typical features of a well-differentiated papillary mesothelioma were recognized. The patient underwent tumor debulking. Two years later he is symptom free. This case study, much similar to another 38 reported cases in the MEDLINE database, illustrates the characteristic features of this rare malignancy that should be recognized and distinguished from other, common, more aggressive neoplasms involving the peritoneum.

The relationship between heart rate variability and epileptiform activity among children--a controlled study.

Autonomic symptoms frequently occur during epileptic seizures. Attention has been mainly devoted to cardiovascular changes. We studied the relationship between heart rate variability (HRV) and epileptiform activity in children with epilepsy.Simultaneous electroencephalograms and electrocardiograms were recorded in 36 children diagnosed with epilepsy and in 36 children with unrelated conditions who served as a comparison group. Heart rate variability was evaluated by time-domain analysis, before, after, and during an epileptiform event, a benign abnormal event and baseline activity.An age-related change in the HRV associated with an epileptiform event was noted in the study group but not in the comparison group. No other significant differences in HRV were noted between the two groups or between true and benign abnormal events.Age seems to be a significant covariate in the analysis of HRV in children with epilepsy. Epileptiform activity is not associated with a significant change in HRV in children.
