A total of 213 fine needle aspirations from pulmonary lesions in 193 patients performed from January, 1986 to March, 1989 were analyzed. The cytologic diagnoses were unsatisfactory in 10, negative in 60, atypical in 6, suspicious in 11 and malignant in 126 cases. The cytologic types of the malignant cases were 47 squamous cell carcinomas, 40 adenocarcinomas, 10 small cell carcinomas, 6 large cell carcinomas and 10 metastatic tumors. They were verified by the histologic confirmation in 31 cases and by the clinical data in the remainder. There were 5 false-negative cases and none was false-positive, representing 96% sensitivity and 100% specificity. Primary lung cancers were accurately typed in 73% of histologically confirmed case. Cell blocks, prepared in 99 cases, were helpful in tumor typing of 11 cases.

Adenoid cystic carcinoma of the lung is histologically and ultrastructurally identical to the salivary gland tumor of the same name and is characterized by infiltrative growth, local recurrence, and usually a prolonged clinical course. We have recently experienced two cases of adenoid cystic carcinoma arising in the lung. Case 1 was a 59 year-old male who presented with cough, fever, and chill of 1.5 months' duration, and case 2 was a 61 year-old male who was incidentally found to have a 3 to 4 cm sized lobulated mass in the right upper lobe. After being worked up, both patients underwent right pneumonectomy. In case 1, a 3x2 cm sized tumor was located in the lower bronchus, partly elevating toward the lumen and partly infiltrating into regional lymph nodes and lung parenchyma showing grayish-white and solid cut surface. Case 2 was a 3.5x3.5 cm sized upper bronchial tumor resembling the former in appearance. Histologically, the tumors were composed of small round hyperchromatic cells, forming solid, cribriform, acinar, or tubular structures. Luminal spaces in tumor cell nests contained PAS-positive mucinous or hyaline material. Among the tumor cells, scattered islands of normal submucosal gland were noticed.

Holmium laser enucleation of the prostate (HoLEP) is a minimally invasive procedure and a size-independent treatment for benign prostatic hyperplasia with excellent long-term surgical outcome. HoLEP has become an alternative to conventional transurethral resection of the prostate or open prostatectomy owing to its efficacy and safety. Although HoLEP is known to have a steep learning curve, very few articles have addressed the technical aspects of HoLEP. Herein, we described detailed techniques and tips for HoLEP as performed at Seoul National University Hospital in a step-by-step manner with extensive review of the literature.

There have been many reports regarding complications associated with cardiopulmonary resuscitation(CPR) and it may be true that there are many unrevealed complications. Although it is used to say that 'any CPR is better than no CPR', inadvertent or inadequate CPR may insult in serious organ injury. This report describes a 64-year-old woman who suffered Mallory-Weiss tear resulting from inadvertent cardiopulmonary resuscitation by a bystander who had never been trained. Possible mechanisms of gastric injuries caused by CPR are suggested, and importance of adequate CPR training are emphasized in this report.

PURPOSE: To evaluate the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for extremely large prostates. MATERIALS AND METHODS: Patients undergoing HoLEP between July 2008 and December 2013 from the Seoul National University Hospital Benign Prostatic Hyperplasia Database Registry were retrospectively analyzed. The patients were divided into three groups according to their total prostate volume (TPV): group A (TPV<100 mL), group B (100 mL< or =TPV<200 mL), and group C (TPV> or =200 mL); the clinical data of the three groups were compared. All patients were followed up 2 weeks, 3 months, and 6 months after surgery. RESULTS: A total of 502 patients (group A, 426; group B, 70; group C, 6) with a mean age of 69.0 (standard deviation, +/-7.3) years were included in our analysis. The mean prostate volume and prostate-specific antigen level were 68.7+/-36.9 mL and 4.15+/-4.24 ng/mL, respectively. The enucleation and morcellation times were longer in group C (p<0.001), and the enucleation efficacy was higher in this group (p<0.001, R2=0.399). Moreover, the mean postoperative catheterization and hospitalization periods were significantly longer in group C (p=0.004 and p=0.011, respectively). However, there were no significant differences between the groups in any other postoperative events, including recatheterization, reoperation, urinary tract infection, clot retention, and bladder neck contracture (p range, 0.516-0.913). One patient in group C experienced recurrence of the urethral stricture. CONCLUSIONS: HoLEP in patients with an extremely large prostate can be performed efficiently and safely.

Traumatic cleft earlobes are a common problem encountered by plastic and reconstructive surgeons. Various techniques have been reported for the repair of traumatic cleft earlobes. Usually, the techniques of split earlobe repair are divided into two categories, namely straight- and broken-line repairs. Straight-line repair is simple and easy, but scar contracture frequently results in notching of the inferior border of the lobule. It can be avoided by the broken-line repair such as Z-plasty, L-plasty, or a V-shaped flap. Between April 2016 and February 2017, six patients who presented with traumatic cleft earlobe underwent surgical correction using a combination of the inverted V-shaped excision technique and vertical mattress suture method. All the patients were female and had a unilateral complete cleft earlobe. No postoperative notching of the inferior border the lobule occurred during 6–16 months of follow-up. Without the use of a broken-line repair, both the patients and the operators attained aesthetically satisfactory results. Therefore, the combination of the inverted V-shaped excision technique and vertical mattress suture method is considered useful in the treatment of traumatic cleft earlobes.

PURPOSE: To evaluate the effect of age on the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for the treatment of symptomatic benign prostatic hyperplasia (BPH). METHODS: A total of 579 patients underwent HoLEP procedure performed by a single surgeon (SJO) between December 2009 and May 2013. The perioperative and functional outcomes of patients in the age groups of 50-59 (group A, n=44), 60-69 (group B, n=253), 70-79 (group C, n=244), and ≥80 years (group D, n=38) were compared. The Clavien-Dindo system was used to evaluate clinical outcomes. The International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), postvoid residual (PVR) urine volume, and urinary continence were used to assess functional outcomes. RESULTS: In this study, the patients ≥80 years had significantly higher presence of hypertension (P=0.007), total prostate volumes (P=0.024), transitional zone volume (P=0.002), American Society of Anesthesiologists scores (P=0.006), urinary retention (P=0.032), and anticoagulation use (P=0.008) at preoperative period. Moreover, the mean values of operation time, enucleation time, morcellation time, and enucleation weight were higher in group D compared with other group patients (P=0.002, P=0.010, P<0.01, and P=0.009, respectively). Patients aged ≥80 years had a longer hospital stay time (2.9±1.8 days) than other groups (group A, 2.3±0.7 days; group B, 2.3±0.7 days vs. group C, 2.4±0.7 days; P=0.001). All groups were similar in regard to the incidence of complications (Clavien-Dindo grade) post operatively (P>0.05). All the patients in the present study showed improvement in functional outcomes after HoLEP. By the sixth month, there were no significant differences in IPSS, quality of life, Qmax, and PVR among the groups (P>0.05). CONCLUSIONS: Compared with younger patients, the patients aged ≥80 years had a similar overall morbidity and 6-month functional outcomes of HoLEP. HoLEP is a safe and effective treatment for BPH among the elderly.
