COEXISTENCE OF TWO CHRONIC NEUROPATHIES IN A YOUNG CHILD: CHARCOT-MARIE-TOOTH DISEASE TYPE 1A AND CHRONIC INFLAMMATORY DEMYELINATING POLYNEUROPATHY

We report an 18-month-old Charcot-Marie-Tooth type 1A (CMT1A) patient who developed a rapid-onset neuropathy, with proximal and distal weakness, and non-uniform nerve conduction studies. The neuropathy responded well to immunomodulation, confirming the coexistence of an inherited and an inflammatory neuropathy. Unexpected clinical and/ or electrophysiological manifestations in CMT1A patients should alert clinicians to concomitant inflammatory neuropathy. In addition, this association raises reflections about disease mechanism in CMT1A. Muscle Nerve 42: 598-600, 2010

Cross-cultural adaptation and reliability of Child-Initiated Pretend Play Assessment (ChIPPA)

Background. Play is an indication of a children`s development. Purpose. Organize a culturally adapt the Child-Initiated Pretend Play Assessment to Brazilian population. Method. Translation and cultural adaptation procedures consisted of translation, synthesis, back translation, author`s approval, and pretest of the assessment. For the pretest, 14 typically developing children were assessed. Was evaluated the use of play materials, duration of the assessment, and reliability. Findings. Play materials and duration of the assessment were appropriate for Brazilian children. Analysis of intra-rater reliability showed good agreement ranging from 0.90 to 1.00. Inter-rater reliability showed good to moderate agreement for five items ranging from 0.76 to 0.59. Four items showed chance to poor agreement (rho = -0.13 to 0.50). Implications. Results of the pretest indicate the Brazilian version of the ChIPPA is potentially useful for Brazilian children. ChIPPA training in Portuguese in Brazil with play observation feedback is recommended to improve inter-rater reliability.

Secondary PSF/TFE3-associated renal cell carcinoma in a child treated for genitourinary rhabdomyosarcoma

Xp11.2 translocation-associated renal cell carcinoma (RCC) is a rare tumor that accounts for at least one-third of childhood RCC. Different reports have emphasized that previous radio/chemotherapy might be involved in its pathogenesis. We describe a child who developed a t(X;1) (p11.2;p34) associated RCC after previous treatment for genitourinary rhabdomyosarcoma in infancy. The presence of the PSF-TFE3 fusion has only been described in a very limited number of cases. Our report expands the spectrum of tumors in which RCC can arise in the pediatric age group after chemotherapy.

Vitamin A deficiency among Brazilian school-aged children in a healthy child service

Background/Objectives: Vitamin A deficiency (VAD) is a world public health problem contributing to the increase in childhood morbidity and mortality in developing countries and severe deficiency of vitamin A may lead to xerophthalmia and blindness. The objective of this study was to determine the prevalence of VAD among Brazilian school-aged children attended at a primary health unit and to verify if some considered risk factor was associated with VAD in this group. Subjects/Methods: A descriptive prospective transverse study was conducted on 103 randomly selected children. A total of 54 boys and 49 girls aged 5.5-11 years had the relative dose-response (RDR) test performed on. Possible ocular alterations related to vitamin A and the status of anemia, serum zinc, some acute-phase proteins, and anthropometric situation were determinate by an analytic design. Results: No child presented xerophthalmia. Serum retinol values lower than 1.05 and 0.7 mu moll(-1), respectively were found in 26.2 and 5.8% of the children. The prevalence of hypovitaminosis detected by RDR test was 20.4%. The following variables and their relationship with VAD were evaluated: sex (P = 0.33; 95% confidence interval 0.61-4.34), weight and height (P >= 0.5), hemoglobin (P = 0.15), C-reactive protein (P = 0.56; 95% confidence interval 0.75-18.26), alpha-1-acid-glycoprotein (P = 0.56; 95% confidence interval 0.15-15.42) and serum zinc (P = 0.31). None of these variables was related to VAD. Conclusions: In this population, the prevalence of VAD detected could be considered a public health problem. School-aged children can be considered at risk for VAD mainly of a subclinical level, even without some associated risk factors.

Hepatoportal Sclerosis and Extrahepatic Portal Venous Obstruction Associated with Anti-phospholipid Antibody Syndrome in Child

We report a 2-year-old child with extrahepatic portal venous obstruction, hepatoportal sclerosis and pulmonary thromboembolism whose sole hypercoagulability factor was the presence of anti-phospholipid antibodies.

Illicit Opiate Abuse

Illicit opiate use, especially injected drugs, contributes to premature mortality and morbidity in many developed and developing societies. The economic costs of illicit drug use are substantial. Fatal overdoses and HIV/AIDS resulting from sharing dirty needles and injecting equipment are major contributors to mortality and morbidity. Illicit opioid use accounted for 0.7 percent of global disability–adjusted life years in 2000. An estimated 15.3 million people, or 0.4 percent of the world population ages 15 to 64, used illicit opioids in 2002, with more than half using heroin and the rest using opium or diverted pharmaceuticals such as buprenorphine, methadone, or morphine. The most popular interventions for illicit opioid dependence in many developed societies have been law enforcement efforts to interdict the drug supply and enforce legal sanctions against drug use. One consequence has been that illicit opioid users have been exposed to the least effective intervention: imprisonment for drug or property offenses. The most effective intervention to reduce blood–borne virus infection resulting from illicit drug injections is provision of clean injecting equipment to users. This intervention has been widely supported in developed countries, but less so in developing countries. In addition, vaccinations are effective against hepatitis B. In treatment settings, the most popular interventions have been detoxification and drug–free treatment, which has proven the least productive in retaining opioid–dependent people in treatment. Opioid agonists have a niche role in treatment of opioid dependence, especially if their efficacy improves with development of long–acting injectable forms of the drug.

Low-grade astrocytoma in a child with encephalocraniocutaneous lipomatosis

Encephalocutaneous lipomatosis (ECCL), or Haberland syndrome, is an uncommon congenital disorder with unique cutaneous, ocular and neurological features. In the present article, we describe a 3-year-old boy with ECCL who developed an extensive and recurring intraventricular low-grade glioma with atypical pathological features and elevated mitotic index. Cytogenetic analysis from tumor sample was also performed. This is the first report of a low-grade astrocytoma occurring in a child with ECCL. Whether or not the origin of the tumor is associated to the pathogenesis of the underlying syndrome is a matter for further investigation.

Rare case of unifocal Langerhans cell histiocytosis in four-month-old child

Langerhans cell histiocytosis (LCH) comprises a group of disorders, the common feature of which is Langerhans cell proliferation. The clinical presentation is highly varied. The severity and prognosis of the disease are dependent on the type and extent of organ involvement. This paper reports a rare case of a four-month-old white male with unifocal LCH limited exclusively to the mandible, discussing the diagnosis, radiographic and immunohistochemical aspects, treatment and monitoring multidisciplinary of the case.

Angiomyolipomatous hamartoma of the upper lip: A rare case in an 8-month-old child and differential diagnosis

Hamartoma is a proliferation of normal tissues that are considered endogenous to the site of occurrence. In the head and neck region, hamartomas composed of other tissues different from blood and lymphatic vessels (hemangiomas and lymphangiomas) are very uncommon. We report an unusual case of upper lip angiomyolipomatous hamartoma in an 8-month-old patient. The patient underwent surgical treatment and the 1-year follow-up revealed no signs of recurrence. Angiomyolipomatous hamartoma is a very rare condition in the paediatric population group, especially in the head and neck region. It should be considered in the differential diagnosis of congenital lesions in childhood. (C) 2010 European Association for Cranio-Maxillo-Facial Surgery.

Family size, economics and child gender preference: A case study in the Nyeri district of Kenya

Kenyan women have more children, especially in rural areas, than in most developing nations. This is widely believed to be an impediment to Kenya’s economic development. Thus, factors influencing family size in the Kenyan context are important for its future. A brief review of economic theories of fertility leads to the conclusion that both economics and social/cultural factors must be considered simultaneously when examining factors that determine the number of children in a family. The need to do this is borne out in Kenya’s situation by utilising responses from a random sample of rural households in the Nyeri district of Kenya. Economic and social/cultural factors intertwine to influence family sizes in this district. After providing a summary of the main statistical results from the survey, we use multiple regression analysis to explore the influences of a woman’s age, level of education, whether she has outside employment, whether the family keeps livestock, whether she expresses a preference for more boys than girls, whether the family uses only family labour (including child labour) and the size of the farm, which is used as a proxy for family income. It was found that preference for male children has an important positive influence on family size in this district. Women were found to have greater preference for male children than their male counterparts possibly because of their fear of being disinherited if they do not produce an heir for their husbands. Preference for sons was also found in allocation of human capital resources at the household level in that the female respondents were found to have lower levels of education than their male counterparts. Various long-term policies are outlined that may help to reduce the number of offspring of women in Kenya.
