Development of Internal Carotid Artery pseudoaneurysms (ICAp) after transsphenoidal surgery is extremely rare, occurring only in 0.4% of cases. Surgical treatment of ICAp poses a real challenge to the neurosurgeon as treatment may require parent vessel sacrifice or artery reconstruction with bypass grafting. Furthermore, surgical resolution of these lesions is rarely reported in the literature.The internal carotid artery is prone to iatrogenic injury in transsphenoidal surgery due to its frequent involvement in pituitary adenomas. Intracranial pseudoaneurysms may be at high risk for rupture and increased morbidity and mortality. Here we present a case of a patient with an ICAp rupture two months after transsphenoidal surgery for a pituitary adenoma.

Congenital adrenal hyperplasia (CAH), an autosomal recessive disorder, is due to deficiency of the enzymes involved in adrenal steroidogenesis. Phenotypic manifestations vary as a result of the degree of glucocorticoid or mineralocorticoid deficiency and androgen excess present. Among Filipinos, the estimated crude incidence of CAH is approximately 1 in 7,000, which is higher than what is reported in most populations. More than 90% of all cases result from a 21-hydroxylase (21-OH) (cytochrome P450c21) enzyme deficiency involving two 21-OH genes, the active gene (CYP21) and a pseudogene (CYP21P). Studies have shown that mutations result from unequal crossover during meiosis which leads to complete deletion of the gene, gene conversion events or to point mutations. To date, there are no published data on the types of mutations present among Filipinos diagnosed with congenital adrenal hyperplasia. The objective of this study is to describe the profile of Filipino patients diagnosed with CAH and to determine the disease-causing alleles in the 21-OH gene of these patients. Using a method of combined differential polymerase chain reaction and amplification created restriction site approach, direct probing for the presence of known mutations in exons 1,3,4,6,7,8 and intron 2 of the CYP21 and CYP21P genes among Filipino patients with CAH was performed. A total of 12 unrelated CAH patients were examined. A majority of these cases had a premature splicing error mutation at nucleotide 656 of intron 2. The determination of the most frequent alleles in our population can facilitate rapid screening for mutations in the 21-OH gene and lead to a definitive diagnosis of CAH.

PURPOSE OF THE STUDY: Basal cell carcinoma (BCC) remains as the most common cutaneous neoplasm in the Philippines consisting of more than 60% of all skin cancers. Anacardium occidentale (Linn.) cashew extract, which had been used successfully in the removal of warts and moles in previous studies, is presented as a therapeutic option in BCC.
METHODS: An open-label prospective study was conducted on 36 patients (mean age of 65 years) with documented BCC lesions on middle third of the face. Cashew nut extract (DeBCC) application was offered to these patients as an alternative option to very unacceptable extirpative surgery offered by general and plastic surgeons as treatment for their lesions. Lesion size ranged from 7.5- 64 mm. (26.26 mm). Topical treatment was applied every 1-2 weeks, as needed. Follow-up examinations with photographic documentation were made every week to evaluate success of the treatment.
RESULTS: After a mean of 7 treatment applications (range of 1-20) all the lesions were undetectable on clinical examinations. Mild tingling sensation, which was reported by all patients during the treatment applications, was tolerable on all occasions. With follow-up ranging from 5-60 months (38.72 months), 16 patients completed the planned 5 - year post-treatment follow-up period. There were no recurrences detected.
CONCLUSIONS: Anacardium occidentale (Linn.) cashew extract (DeBCC) presents a viable and acceptable treatment option in primary BCC. The importance of this treatment option could be stressed in patients with lesions not amenable to the prescribed wide margin of resection needed in surgery.
