BACKGROUND: The purpose of this study was to evaluate the angle between the long head of the biceps tendon (LHBT) and the glenoid during arthroscopic surgery and its correlation with biceps subluxation on magnetic resonance imaging (MRI). Furthermore, we evaluated the relationship of this angle with subscapularis tears and biceps pathologies. METHODS: MRI and arthroscopic images of 270 consecutive patients who had undergone arthroscopic surgery were retrospectively evaluated. On MRI, 60 shoulders with biceps subluxation and 210 shoulders without subluxation were identified. On the arthroscopic view from the posterior portal, the angle between the LHBT and the glenoid (biceps-glenoid angle) was measured. The biceps-glenoid angle, tears of the LHBT, degenerative superior labrum anterior to posterior (SLAP) lesions, and presence of a subscapularis tear were compared according to the presence of biceps subluxation on MRI. RESULTS: In the subluxation group, 51 (85%) had a subscapularis tendon tear and all shoulders showed biceps tendon pathologies. In the non-subluxation group, 116 (55.2%) had a subscapularis tendon tear, 125 (60%) had tears in the biceps tendon, and 191 (91%) had degenerative SLAP lesions. The incidences of subscapularis tears (p < 0.001) and biceps pathologies (p < 0.001) showed significant differences. The mean biceps-glenoid angle was 87.0° (standard deviation [SD], 11.4°) in the subluxation group and 90.0° (SD, 9.6°) in the non-subluxation group, showing a statistically significant difference (p = 0.037). CONCLUSIONS: Shoulders with subluxation of the biceps tendon on the preoperative MRI revealed more pathologies in the subscapularis tendon and biceps tendon during arthroscopy. However, the arthroscopically measured biceps-glenoid angle did not have clinical relevance to the determination of subluxation of the LHBT from the bicipital groove.

Coronary stent embolization is a rare event but may result in clinically relevant cardiac ischemia or peripheral embolization during the procedure. We report a case of systemic embolizations of two coil stents during the primary PTCA in acute myocardial infarction, who were treated successfully with a double wire helix technique and a gooseneck snare. Although in our experience this rare complication did not produce any clinical complications, care should be taken to prevent this possibility, especially in patients with significant vessel tortuosity, calcification, total occlusion, or mild stenosis proximal to the target lesion.

Surgical endarterectomy has been shown to be superior to medical treatment in the management of severe carotid stenosis. Endarterectomy, although effective, does have limitations, and percutaneous transluminal angioplasty with stent may offer an alternative modality of treatment. We report on a patient with severe coronary disease that femoral arterial cannulation was not possible due to aorto-femoral shunt operation and absent pulse. The transradial approach was used for aortography, bilateral carotid angiography and successful elective stent deployment in the left internal carotid artery. The transradial approach might be useful alternative in case of problems with femoral approach.

A fixed drug eruption is a cutaneous reaction caused by various drugs, which include phenazone derivatives, barbiturates, sulfonamides, tetracyclines and phenolphthaleins. An eruption caused by piroxicam is very rare and there have been no previous reports in Korea. A 49-year-old woman was seen with mutiple erythematous patches and some bullae that appeared after oral administration of piroxicam. The patient had had two similar episodes after oral administration of piroxicam. We performed patch test with piroxicam and could confirm a fixed drug eruption caused by this durg.

PURPOSE: Painful plantar callosities under the second, third or fourth metatarsal head have been controverted about its treatment mordalities. We performed the vertical chevron osteotomy in patients with painful callosities on the second and third metatarsal head, and evaluated the outcome clinically. MATERIALS AND METHODS: Fourteen cases from 10 patients who had plantar keratosis were operated by vertical chevron osteotomy from March 2005 to October 2008. We used K-wire fixation for all cases. We evaluated the clinical results by the patients' satisfaction and disappearance of plantar lesion. RESULTS: The plantar keratosis was completely disappeared in 8 cases and partially in 5 cases. In 2 cases, patients expresses their pain caused by constant metatarsalgia that was suspected to be dorsal incisional pain and joint capsulitis. Transmetatarsalgia was not appeared. CONCLUSION: We consider vertical chevron osteotomy as a good surgical method for treatment of plantar keratosis.

The term "disorders of sex development" (DSD) includes congenital conditions in which development of chromosomal, gonadal or anatomical sex is atypical. Steroid 5-alpha reductase type 2 deficiency (5alpha-RD2) is an uncommon autosomal recessive disorder of sexual differentiation. It results from impaired conversion of testosterone (T) to dihydrotestosterone (DHT) due to mutations in the steroid 5-alpha reductase type 2 (SRD5A2) gene. It is characterized by a lack of masculinization in XY individuals due to failure to convert testosterone to dihydrotestosterone. More than 40 mutations have been reported in all five exons of the SRD5A2 gene. Here, we report on a 17-day-old Korean newborn who was confirmed to have 5alpha-RD2 by SRD5A2 gene analysis. He manifested micropenis, hypospadia and bilateral cryptorchidism without skin hyperpigmentation. T/DHT ratio after human chorionic gonadotropin (hCG) stimulation was slightly increased and genetic analysis of SRD5A2 revealed compound heterozygous mutations, c.657C > G (p.Phe219Leu) and c.656del (p.Phe219SerfsX60), the former of which is a novel mutation. We report a novel SRD5A2 gene mutation in a Korean newborn with 5alpha-RD2.

PURPOSE: Phenylketonuria(PKU) is an inborn error of metabolism and a genetic disorder resulting from a deficiency of phenylalanine hydroxylase(PAH) and decreased activity of tetrahydrobiopterin(BH4).In this study the correlation between the DNA mutation and clinical manifestations was investigated and PAH DNA mutations were compared bewteen Asian and Caucasian populations. METHODS: DNA was isolated from peripheral leukocytes. The PAH gene was amplified by Polymerase Chain Reaction(PCR) and the sequence was analyzed with Multiplex Ligation-dependent Probe Amplification(MLPA). RESULTS: We characterized the PAH gene of 102 independent Korean patients with PKU. PAH nucleotide sequence analysis revealed 44 different mutations, including 10 novel mutations comprising 9 missense mutations(N207D, K95del, A447P, G344D, P69S, S391I, A202T, G103S, and I306L) and 1 novel splice-site variant mutation(IVS10-3C>G). R243Q was the most prevalent mutation in this study. A259T has not previously been reported in Asian populations, but we found that this mutation had a frequency of 10.1% in our study. Furthermore, the genotypes of BH4 responsive patients were analyzed and were divided into two groups: BH4 medication-only group and BH4 medication with diet therapy group. In the BH4 medication-only group and BH4 medication with diet therapy group, R241C was the most common mutation. CONCLUSION: Novel mutations in the PAH gene of PKU patients are still being discovered. Additional information as to the frequency of mutations in the tetrahydrobiopterine responsive gene is also accumulating. We anticipate that knowledge of these PKU gene mutations will assist the diagnosis, genetic counseling, and therapeutic treatment of PKU patients in future.
