Clinical Characteristics and Outcomes of Pediatric Cerebral Venous Sinus Thrombosis: An Analysis of 30 Cases in China.

Background: Cerebral venous sinus thrombosis (CVST) in children is rare in a clinical setting. The aim of this study was to summarize the etiological, clinical, and imaging characteristics of CVST in children. Methods: We retrospectively analyzed the data of 30 patients with a diagnosis of CVST who were admitted to Children's Hospital of Fudan University from 2008 to 2018. The medical records, including clinical manifestations, laboratory data, neurological findings, treatment, and short-term prognosis were analyzed. Results: Etiologically, the causes of CVST were infection (7/30), tumor (3/30), nephritis or nephrotic syndrome (8/30), traumatic brain injury (1/30), and undefined disease (11/30). All 30 cases were diagnosed with CVST after a neuroimaging examination using brain magnetic resonance imaging (MRI) combined with magnetic angiography venography (MRV). With regard to short-term prognosis, all the patients were treated with anticoagulants, after which 26 cases improved. Conclusions: CVST patients do not typically present with specific clinical manifestations, which leads to a high rate of misdiagnosis and delayed therapy. Increased consideration and prompt MRV checkup plays a key role in achieving an accurate diagnosis. Overall, anticoagulation is a safe and effective treatment for CVST.

Six-month efficacy of the Ketogenic diet is predicted after 3 months and is unrelated to clinical variables.

OBJECTIVE: The aim of this study was to evaluate the 6-month efficacy of a Ketogenic diet (KD) in children with drug-resistant epilepsy and to analyze the associated factors that affect the efficacy of a KD. METHODS: Eighty-seven pediatric patients with drug-resistant epilepsy who followed a KD for at least 6 months were included in this study. The efficacy of a KD was assessed based upon the seizure frequency, as recorded by parents and caregivers. The number of cases and the degree of efficacy in different age ranges were also considered. The effects of gender, age, seizure type, etiology, blood glucose and ketone levels, seizure frequency before the diet, and cognition on the length of time on a KD were analyzed. RESULTS: (1) There was no significant correlation between the length of time on a KD and efficacy (χ(2)=2.31, P=0.51). The 3-month efficacy of a KD was 51%, which did not further increase when the course was extended to 6 months. (2) There was a positive correlation between increased cognition and the efficacy of a KD after 3 months (γ=0.31, P=0.003). (3) The efficacy analysis of 3-month treatment with a KD revealed, with respect to seizure types, that there were 37 patients with multiple seizure phenotypes and 50 patients with a single seizure phenotype. The overall efficacy of a KD in the group with multiple seizure phenotypes was 61%. The efficacy of a KD was not statistically associated with a coexisting syndrome or a type of syndrome; however, the efficacy of a KD had a tendency to be increased in certain types of syndromes. The overall efficacy in the group with a single seizure phenotype was 87%, and the efficacy was not associated with seizure type. (4) The 3-month efficacy of a KD was not correlated with age, gender, etiology, blood glucose or ketone levels, or the seizure frequency before treatment. CONCLUSION: An observation time of 3 months is appropriate for assessing the efficacy of a KD in treating children with drug-resistant epilepsy. The factors that likely influence the efficacy of a KD are unclear, but our study suggests that incorporating more patient samples will help determine whether patients with certain syndromes can benefit from a KD.

[Prevalence of chronic headache in Shanghai children and adolescents: a questionnaire-based study].

OBJECTIVE: To explore the prevalence and characteristics of chronic headache in children and adolescents in Shanghai and to collect messages concerning the impact and compliance of medication for migraine. METHODS: A population-based questionnaire study was conducted among subjects 6 - 15 years of age sampled from primary and junior high schools in Shanghai and the subjects were followed up. RESULTS: (1) The prevalence: 8701 (88.6%) out of 9857 pupils responded to the questionnaire; 17% of the respondents had headache and in 86.4% of them the reason of headache was unknown. The prevalence of chronic headache in Shanghai children and adolescents was 7.8%, there was no significant difference between both genders (chi(2) = 0.010, P > 0.05). (2) The prevalence of chronic headache increased with age, the incidence was higher in boys before 12 years of age, while higher in girls after 12 years of age. (3) Characteristics of chronic headache: the proportion of unilateral, bilateral and headache of unknown site was similar; in most of the cases headache was localized in the temple (35.2%) and forehead region (25.6%), the duration of headache was short, always accompanied by gastrointestinal symptoms. Half of the patients reported that the headache had affected their study and daily life. (4) The status of using health care facilities: 24% of the students sought medical assistance during their headache episodes and among them only 30.9% took medicine. (5) Over-fatigue (51.4%), followed by insufficient sleep (40.4%), emotional changes (38.5%) were the main aggravating factors. The headache was also associated with positive family history and stress in studying. CONCLUSIONS: Headache is a common complaints of children, affecting the patients' study and daily life. But many patients with headache were not treated properly, therefore, the medical and educational sectors and the society should pay more attention to this problem.

Digital reconstruction and donor site resurfacing: a two-flap technique.

Use of a great toe pulp flap is one of the methods to repair partial soft-tissue defect of the thumb or other digits. However, the conventional application of free skin grafts to close the donor site may bring donor-site morbidity. The authors present a two-flap technique that a reverse first dorsal metatarsal artery (FDMA) flap resurfaces the defect of the free great toe pulp flap. Six patients with soft-tissue defects of the thumbs or fingers were treated with this technique. Both the pulp and reverse flaps survived uneventfully after reconstruction of the thumbs and fingers. The reverse flap to resurface the donor site on the great toe was sensate and durable. Satisfactory appearance and function were gained in all patients. Results revealed that this technique can be accepted as an alternative method when treating soft tissue defect of the thumb or finger.

[Reverse first dorsal metatarsal artery island flap for coverage of donor defect of great toe after free lateral pulp flap transfer].

OBJECTIVE: To employ reverse first dorsal metatarsal artery island flap to recover the donor site of great toe after free lateral pulp flap transfer, and decrease the morbidity of microsurgical donor site. METHODS: From February 2000 to June 2004, 12 cases of soft tissue defect in thumb and finger were treated by free lateral pulp flap of great toe transplantation, and that the secondary defect of great toes were repaired by reverse first dorsal metatarsal artery flap according to the anatomical communicating between first dorsal metatarsal artery and plantar metatarsal artery. The donor exposure of dorsal pedis were straightly sutured. RESULTS: All the lateral pulp flaps of great toe and the reversed first dorsal metatarsal flaps survived uneventfully with desirable appearance and sensation. In thumb and finger defect reconstructed with lateral pulp flaps of the great toe, there was in mean static two-point discrimination of 6 mm at 10 month follow-up, that was 10 mm in reverse flaps. CONCLUSIONS: It is an instructive and practical creation to adopt the reverse first dorsal metatarsal artery flap to recover the raw surface in the lateral aspect of the great toe, which minimizes the morbidity at the donor site and gains the twin-win results.
