Holoprosencephaly is a rare complex cerebral anomaly produced by a failure of cleavage of the prosencephalon. The association of brain anomalies and facial dysmorphism is a typical finding. There are three types(alobar, semilobar, and lobar) of holoprosencephaly. Among these the alobar type has the worst prognosis. The early antenatal diagnosis of the holoprosencephaly is very important determinant for initiating the therapeutic abortion. We report 3 cases of alobar holoprosencephaly with the brief review of the literature.

A 20-day-old previously well neonate presented with a 3-day vesiculopapular rash and was admitted to the paediatrics ward. He received extensive workup and treatment with IV acyclovir. The disease ran a mild, uncomplicated course, and recovery. His mother was found to be immune to varicella, having had the disease as a child. However, her immunity had not transferred to the neonate, which was unexpected. A literature review revealed that maternal varicella antibodies do not necessarily prevent infection but may help the infant avoid severe or complicated disease. A review of the management of neonatal varicella in both the immune and the non-immune mother which put the child at risk is also done. Vaccination of all susceptible young females prior to pregnancy will help to reduce the incidence of neonatal varicella in infants and is strongly encouraged. Vaccination of household contacts especially siblings, is also encouraged. Family Physicians should remain open to the diagnosis of neonatal varicella, even when the mother has a history having chickenpox as a child.

Dysphagia is a common problem among the elderly either as a result of age-related loss of musculature and function involved in the act of swallowing, and/or because of neurological, degenerative, respiratory and musculoskeletal diseases that cause decreased swallowing function. Assessment for dysphagia is important to prevent serious complications such as aspiration pneumonia. Referral to the speech-language therapist for comprehensive assessment paves the way for proper management. The management may include diet modification, compensatory swallowing techniques, swallowing exercises or use of feeding tubes and facilitative devices.

Fetal abnormalities in central nervous system are now recognized more often with the increasing use of high-resolution prenatal sonography. Arachnoid cysts, because of their compression of adjacent brain tissue, may require neurosurgical intervention but otherwise they have a good long- term prognosis. The differential diagnosis of intracranial lesions is important to allow accurate counselling and also to optimize neonatal management. We report the two cases of fetal arachnoid cyst diagnosed with prenatal ultrasonography

Duchenne muscular dystrophy (DMD) is a progressive form of muscular dystrophy caused by mutations in the dystrophin gene. Patients with DMD are more likely to have cerebral infarction than normal populations, possibly due to low ejection fraction and cardiomyopathy, and also higher epilepsy prevalence. Careful history taking and neurological examination are needed for differentiating new symptoms from preexisting weakness in DMD. Here, we present a young male with DMD and acute ischemic stroke followed by recurrent seizures.

Aims: Subterranean termites, Globitermes sulphureus is one of the significant pests for agricultural crops such as coconut and oil palm, and occasionally attacks building structure in Malaysia. Efforts to control subterranean termite infestations depended heavily on liquid termiticide applications. Natural pathogen of termites such as entomopathogenic fungi (EPF) is a promising alternative to chemical control. The objective of this study was to determine the most virulent EPF such as Metarhizium anisopliae, Beauveria bassiana and Paecilomyces sp. against the subterranean termites, G. sulphureus for the development of bio-insecticide for future use of termite control. Methodology and results: Subterranean termites were collected from mound-building termites found in Universiti Malaysia Terengganu (UMT). Cultivating, harvesting and counting of conidia of EPF were carried out to prepare the desired concentrations for screening test and bioassays, which were 1×103 , 1x105 , 1×107 and control. The pathogenicity testing was observed daily within 1 week under laboratory conditions. Screening showed that M. anisopliae was found to be the most virulent compared to B. bassiana and Paecilomyces sp., achieving 100% mortality within 3-4 days. M. anisopliae was then further tested on termites and it was found that concentration of 1×107 showed the lowest LT50 value, while LC50 of M. anisopliae in 1 day was 2.0151×106 . Conclusion, significance and impact of study: It could be concluded that M. anisopliae is the most virulent EPF against termites and the most effective concentration was ±107 followed by strains of B. bassiana and Paecilomyces sp. However, there is limited field evaluation of EPF against termites in Malaysia. Evaluation on the efficiency of M. anisopliae in the field should be conducted so that its efficacy could be proven and marketed.

PURPOSE: Dental trauma is frequently unpredictable. The initial assessment and urgent treatment are essential for dentists to save the patient's teeth. Mobile-phone-assisted teleconsultation and telediagnosis for dental trauma could be an aid when a dentist is not available. In the present in-vitro study, we evaluated the success rate and time to transfer images under various conditions. MATERIALS AND METHODS: We analyzed the image quality of cameras built into mobile phones based on their resolution, autofocus, white-balance, and anti-movement functions. RESULTS: The image quality of most built-in cameras was acceptable to perform the initial assessment, with the autofocus function being essential to obtain high-quality images. The transmission failure rate increased markedly when the image size exceeded 500 kappaB and the additional text messaging did not improve the success rate or the transmission time. CONCLUSION: Our optimal protocol could be useful for emergency programs running on the mobile phones.
