BACKGROUND: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. METHODS: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. RESULTS: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder (8.2 +/- 7.9 mm versus 7.3 +/- 3.4 mm, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. CONCLUSIONS: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

PURPOSE: This study was performed to evaluate chromatin condensation of morphologically mature sperm using a modified aniline blue-eosin (AB-E) staining method in azoospermia. MATERIALS AND METHODS: Chromatin condensation was analyzed using an AB-E staining method in 61 cases (50 patients) of TESE or testicular biopsy with the patient's own sperm. Obstructive azoospermia (OA) was present in 48 cases in 39 patients and non-obstructive azoospermia (NOA) was present in 13 cases in 11 patients, respectively. Immature sperm heads were stained dark blue, whereas mature sperm were stained red-pink by the eosin. The percentage of sperm chromatin condensation was calculated from the ratio of the number of red-pink sperm to the total number of sperm analyzed. RESULTS: The percentage of chromatin maturity was 37.7% vs. 30.3% in OA and NOA, respectively, of the total sperm cell count. The maturity of fresh testicular sperm was 38.3% and 36.3% in OA and NOA, respectively. Also, the maturity of thawed testicular sperm was 34.5% and 10.3% (p<0.05) in OA and NOA, respectively. The maturity of fresh and thawed testicular sperm was 36.3% and 10.3% (p<0.05), respectively, in NOA. These results suggest that chromatin condensation is less stable in sperm of NOA and freezing and thawing procedures may impair sperm chromatin condensation. CONCLUSIONS: In our results, the aniline blue-eosin staining method improved the visualization of excessive histones in sperm and the diagnosis of sperm immaturity in morphologically normal testicular sperm. We found that AB-E staining method can be an effective method for analyzing testicular sperm chromatin condensation in azoospermia.

BACKGROUND: The typical MRI features of hippocampal sclerosis (HS) are volume loss and increased T2 weighted signal intensity. Hippocampal volumetry and T2 relaxometry are useful quantitative methods for presurgical diagnosis of HS, especially in the cases of mild, bilateral or focal hippocampal atrophies. We investigated the value of a new quantitative method using FLAIR (Fluid Attenuated Inversion Recovery) MR images compared to those of visual inter-pretation and MR volumetry. METHODS: Forty-five patients with mesial temporal lobe epilepsy (TLE) and 21 under-went volumetric MRI (T1-weighted, SPGR, T2 weighted, and FLAIR images). All patients underwent anterior temporal lobectomy with amygdalohippocampectomy., where visual analysis and hippocampal volumetry were performed. The absolute and normalized values of hippocampal FLAIR signal intensity [hippocampal FLAIR intensity/superior frontal FLAIR intensity=Hippocampal-Frontal Signal Intensity Ratio (HFSR)] were obtained from both normal subjects and patients with TLE. RESULTS: The pathology of resected hippocampus showed HS in all patients. Visual interpretation of presurgical MRI failed to lateralize HS in 10 patients (22.2%). Among these 10 patients, the HS was lateralized by HFSR method in seven patients (70%) [Five (50%) by right-to-left difference of HFSR and the other two (20%) by analysis of a longitudinal regional curve of HFSR] while it was further lateralized by hippocampal volumetry in only three. CONCLUSIONS: In presurgical evaluation of patients with TLE, the hippocampal FLAIR signal analysis appeared to be complementary to visual interpretation and MR volumetry.

In order to observe the growth and development of Fibricola seoulensis metacercariae, the tadpoles of Rana nigromagulata were experimentally infected with the cercariae. The metacercariae of various developmental stages were recovered from the tadpoles after 2 to 65 days of infection. They were prepared for morphological observation, and were given orally to mice to observe their infectivity. The following results were obtained. All of the tadpoles exposed to the cercariae were observed to harbour the larvae in their abdominal cavity. The young metacercariae of 2 days after infection were 121.1 micrometer long and 63.3 micrometer wide. They grow linearly for the first 14 days to be 262.0 micrometer long and 166.4 micrometer wide. Thereafter, no more growth recognized until 65 days. The larvae of 2 days old were similar with cercarial body and had 2 suckers, a pharynx, two ceca and a primordium of germ cells but no tribocytic organ. On the 8th day, they had tribocytic organ, and their morphology resembled that of mature metacercariae. The metacercariae younger than 10 days could not infect the mice. Only the metacercariae older than 14 days had infectivity. The recovery rate increased by the age of metacercariae from 19.0% in 14 days old to 70.0% in 40 days old. Above findings indicate that the tadpole is indispensible for metacercarial development and it needs at least 2 weeks for maturation. The tadpole is a pivotal host in the life cycle of F. seoulensis for connection between the snail and the frog.

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is a rare congenital cardiovascular anomaly. The mortality rate among infants and children without operation has been eighty to ninety-five percents and few patients survive till teen-age or adulthood. This anomaly was detected during elective coronary angiogram in a 32 year-old female patient with atypical chest pain. Reversible ischemia was demonstrated on myocardial 201Tl-SPECT. Coronary angiogram revealed anomalous origin of left coronary artery from pulmonary artery.

Diabetic neuropathy is one of the most common complications of diabetic mellitus and has myriad clinical presentations. Amitriptyline is an effective drug for painful diabetic neuropathy, but has a wide variety of cardiovascular effects. We report a case of amitriptyline-induced ventricular tachycardia in a patient with painful diabetic neuropathy. A 48-year-old man with no history of heart disease was treated with amitriptyline for the past 2 months. The dosage of this drug was gradually increased and the maximal dose was 170 mg per day. Prior to administration of this drug, his chest X-ray and electrocardiogram were normal. On admission he complained of chest discomfort and palpitation for 3 days, but his vital sign was stable. The electrocardiogram showed a wide QRS complex with a rate of 170 beats per minute. The ventricular tachycardia was successfully treated with electrical cardioversion.

McCune-Albright syndrome (MAS) is a rare disorder that develops from an activating mutation in the Gs gene. It is characterized by an association with Polyostotic fibrous dysplasia, and precocious puberty, Caf-au-lait pigmentation, and other endocrinopathies that result from the hyperactivity of a variety of endocrine glands. Recently we encountered a patient with MAS with fibrous dysplasia, skin pigmentation, acromegaly, hyperprolactinemia and a thyroid nodule. A 23-year-old male presented for an evaluation of a change in his facial structures. Fibrous dysplasia was diagnosed by a bone biopsy and radiographic studies. The GH level increased paradoxically after an oral glucose load. The plasma prolactin, IGF-1 and alkaline phosphatase were high. Thyroid ultrasonography revealed multiple nodules. The brain MRI demonstrated a mass in the left pituitary gland. Genetic analysis identified a change from Arg (CGT) at codon 201 to Cys (TGT).
