Maternal varicella resulting in viremia may transmit the virus to the fetus by either transplacental spread, or by ascending infection from lesion in the birth canal. The characteristic symptoms consist of skin lesions in dermatomal distribution, eye diseases, neurological defects, and limb hypoplasia. Varicella of the newborn is a life-threatening illness that may occur when a newborn is delivered either within five days of the onset of the illness or after postdelivery exposure to varicella. The severity of neonatal disease is dependent upon the timing of maternal illness. The clinical approach to varicella of newborns should emphasize prevention. Our patient was the first child of a 31-year-old mother who had varicella-zoster ten days before delivery. The child showed muscular hypotonia, poor feeding but no skin lesions.

Stiff-person syndrome is a rare disorder, and the natural history of the syndrome has not been completely ascertained. The symptoms range from mild to severe and can progress over time: the final result can be significant disability. However, this syndrome is often misdiagnosed due to a lack of understanding of the clinical manifestations. We report the case of a patient who presented with slowly progressing gait disturbance and lower extremity pain and was later diagnosed as suffering from stiff-person syndrome. The patient experienced symptomatic improvement after the administration of benzodiazepines. No recurrence of symptoms has been reported. If the characteristic clinical features and electromyography findings of the syndrome are accurately interpreted, diagnosis of patients with abnormal muscle tension can be effectively done.

Recent advances in the diagnosis and treatment of inborn errors of metabolism have improved substantially the prognosis of many of these diseases, if diagnosed early enough before irreversible damage occurs. This makes it essential that the practicing pediatrician, especially neonatologists be familliar with the clinical presentations and systematic approaches of these disorders. Characteristic clinical presentations, methods of systematic approach and typing of various disorders is discussed in this review. The signs of neurological dysfunctions of many IEMs manifesting in the neonatal period is very nonspecific, such as poor feeding, poor sucking, apnea or tachypnea, vomiting, hypertonia, hypotonia, seizure, letharginess, consciousness change and coma. Many other non-metabolic severe disorders of neonatal period such as neonatal sepsis and intracerebral hemorrhage share these nonspecific symptoms. Hyperammonemia, metabolic acidosis, ketosis and hyperlatic acidemia are observed in many of these conditions but there are exceptions in which conditions all basal laboratory tests are normal, such as NKH, sulfite oxidase deficiency and peroxisomal disorders. According to the results of basal laboratory tests, IEMs in the neonatal period can be categorized in to 6 types. Grouping of IEMs into 6 types will make confirmatory tests and early emergency treatment more efficient.

Thirteen strains of Clostridium perfringens were isolated from the pigs with hemorrhagic enteritis. The characteristics of the outbreaks, clinical signs and lesions were examined. The biochemical properties, type of toxin and susceptibility to antimicrobial agents of the isolates were investigated. The results could be summarized as follows ; 1. Almost of the pigs affected with hemorrhagic enteritis, 17 cases examined from 1989 to 1992, were piglets less than 7 day old. 2. The average mortality rate of piglet less than 7 day old affected with hemorragic and necrotic enteritis was 48.5%. 3. The clinical signs of pigs with hemorrhagic enteritis were depression, hemorrhagic diarrhea, anemia and dehydration. Necropsy of the infected pigs showed typical hemorrhage of upper intestine and necrosis of mucosal membrane. 4. The characteristic biochemical properties of the isolates were 2-band hemolysis, positive reaction of reverse CAMP test and formation of LV precipitate in egg yolk medium. 5. The toxin type of the 13 isolates, investigated by mouse inoculation test, was all type C strains of Clostridium perfringens. 6. In susceptibility test to antimicrobial agents, 13 isolates of Clostridium perfringens were highly sensitive to ampicillin, enrofloxacin(Baytril), cephalothin, penicillin and trimethoprim-sulfamethoxazole.

Pulmonary giant cell carcinoma is one of the most highly malignant neoplasms of the lung. Although mixed malignant glandular or squamous components may be associated with a giant cell carcinoma, it is a distinct clinical and morphologic entity. We reviewed cytologic presentations of 6 cases of pulmonary giant ceil carcinoma. Cytologically, the single most characteristic feature of giant cell carcinoma was an extremely large, bizarre cancer cell engulfing numerous leukocytes. The nuclei of these cells showed occasional prominent nucleoli, and the cytoplasm was abundant. Giant cells were also seen in other types of pulmonary carcinoma, but the slant cells of this neoplasm could be differentiated from those encountered in undifferentiated large cell carcinoma and squamous cell carcinoma by the abundant cytoplasm, the presence of markedly enlarged nuclei, prominent nucleoli, and a significant degree of phagocytosis. In conclusion, precise diagnosis and classification of lung cancer is imperative because of proved correlation between cell type and prognosis.

Progressive hemifacial atrophy, also known as Parry-Romberg syndrome, is an uncommon degenerative condition which is poorly defined. It is characterized by a slow and progressive atrophy affecting one side of the face. The onset usually occurs during the first two decades of life. Characteristically, the atrophy progresses slowly for several years, and then it becomes stable. Ophthalmic involvement is common, with progressive enophthalmos which is a frequent finding. Cutaneous pigmentation is common in such conditions, however its extension to the conjunctiva is rarely reported. We report a case of Parry Romberg syndrome with characteristic clinical and radiographic presentation accompanied with rare ocular findings. The clinical features, radiological findings, and differential diagnoses to be considered, and the available treatment options are discussed in this report.

The arterial spin labeling (ASL) is a magnetic resonance imaging (MRI) method that can evaluate tissue perfusion using blood in the body. The characteristic of non-invasive examinations without contrast agents and the quantitative measurement of perfusion volume is possible, which are increasingly being used for clinical and research purposes. Up to the present, The ASL method has lower SNR than the perfusion imaging method using contrast agent and because optimization of various parameter in the imaging process is difficult, Which may result in measurement errors. To improve this, ASL methods using various technologies are introduced. This paper briefly introduces the outline of ASL, its features in imaging process, various techniques, and clinical application.

Achondroplasia is one of the most common types of dwarfism and is inherited as an autosomal dominant trait. Clinical features of achondroplasia include disproportionate short stature with normal trunk length, shortening of the extremities, bowing of the lower extremities, short stubby trident hands, spinal stenosis and lumbar lordosis. Characteristic craniofacial features include macrocephaly, prominent forehead, depressed nasal bridge, maxillary hypoplasia, otolaryngeal system dysfunction, and foramen magnum stenosis. These characteristics may lead to number of complications including hydrocephalus, apnea, upper-airway obstruction, otitis media, sinusitis and dental malocclusion. Apart from these features, the affected children have good general health and normal intelligence. Dentists should be aware of the clinical characteristics of achondroplasia and the complications that may arise as a result of this disorder. This case report is to present dental treatment of a patient with achondroplasia under general anesthesia and discuss special considerations.

Phthalimidyl ester of ceftezole (CFZ-PT) was synthesized as a prodrug by esterification of ceftezole (CFZ) with N-bromophthalimide. CFZ-PT was more lipophilic than CFZ when the lipophilicity was assessed by partition coefficients between n-octanol and water at various pH. The pharmacokinetic characteristic of CFZ-PT and CFZ preparations were compared following oral administrations of these compounds to rabbits. CFZ-PT is expected to be metabolized rapidly to CFZ in the body. The metabolism process appears to be hydrolysis of the ester to CFZ, the parent drug of CFZ-PT. In vivo metabolism of CFZ-PT to CFZ was confirmed in rabbit by HPLC analysis. CFZ concentration in the serum samples taken after oral administration of CFZ-PT(equivalent amount of CFZ) were released and higher than those of CFZ. Oral bioavailability of CFZ-PT was 1.9 fold higher than at of CFZ in rabbits because of enhanced lipophilicity and absorption. Finally, it was concluded that CFZ-PT appears useful as a prodrug of CFZ to improve the oral bioavailability of CFZ.
