Pulmonary hamartoma is one of the most common benign lung tumors. Well-known conventional methods of treatment for lung hamartomas include VATS enucleation or wedge resection, bronchoplasty, and others. Here we present a case of endobronchial hamartoma that was successfully treated with cryosurgery by flexible bronchoscopy.

BACKGROUND: When using the anterior approach for performing superficial parotidectomy, the first thing to do is to find the buccal branch of the facial nerve and the parotid duct. The buccal branch usually runs transversely with the parotid duct from the anterior border of the parotid gland. We wanted to check the relationship between the two structures during the operation and to get clinically helpful information. METHODS: Twelve patients with parotid mass were treated with superficial parotidectomy between May 2012 and August 2012. The outline of superficial and deep lobes of the parotid gland, parotid duct, and the buccal branch of the facial nerve were drawn on the transparent film by tracing the structures intraoperatively. RESULTS: In 7 (58.3%) of 12 cases, the buccal branch of the facial nerve was located more caudally than the parotid duct at the anterior border of the superficial lobe of the parotid gland. In 3 cases (25%), the buccal branch was located more cephalically than the parotid duct. The mean distance between two structures were 2.54+/-1.48 mm. In 11 cases, the parotid duct was located deeper than the buccal branch. CONCLUSION: The buccal branch of the facial nerve tends to be located more caudally than parotid duct and runs more superficially than parotid duct in all cases. We identified the relationship between the parotid duct and the buccal branch of the facial nerve during the operations on living subjects, not from the cadavers, so it would be a clinically helpful study which supplied more accurate anatomical information.

PURPOSE: Contralateral reduction mammaplasty at the time of breast reconstruction using autogenous tissue gives aesthetically improved results in the patients with mammary hypertrophy or ptosis. It also reduces required flap size for reconstruction and permits discarding zones of poor perfusion, decreasing flap size- related problems such as partial flap loss or fat necrosis. Considering the high rate of bilaterality of breast cancer, it also provides a good opportunity for exploration and occult cancer diagnosis in such high risk group patients. METHODS: We retrospectively reviewed 45 consecutive patients who underwent simultaneous breast reconstruction and contralateral reduction mammaplasty was performed about surgical technique, pathologic diagnosis, and subsequent treatment. RESULTS: Three occult breast cancers were found in 45 patients(6.7%); one was microinvasive, and the other two were invasive carcinomas and their mean diameter was 1.2 cm. One patient underwent subsequent breast conserving mastectomy, adjuvant radiation and chemotherapy. The others underwent only radiation and hormone therapy. They were followed up for 10 to 42 months without evidence of recurrence or metastasis. CONCLUSION: Occult breast cancer diagnosed in reduction mammaplasty specimen will lead to good prognosis due to its early detection. Treatment options depend on pathologic finding, stage, marginal status, and the timing of diagnosis. We recommend adequate markings for orientation and margins, excision with sufficient margin, and confirmation by frozen biopsy for suspected lesions.

PURPOSE: Using the implant for the breast reconstruction still remains the options, despite the breast reconstruction using autologous tissue is an ideal method. In this study, we used AlloDerm(R) to extend subpectoral pocket for covering implants to reduce implant related complications. METHODS: From January 2005 to June 2007, 18 breasts in 16 patients were reconstructed using implant and AlloDerm(R) immediately after mastectomy. Hospital records, database files, and clinical photographs were reviewed. A ten-point scale was used to evaluate the patient's satisfaction, with a range from 2(poor) to 10 (excellent). RESULTS: Mean age of the patients was 38.7 years at the time of operation. Mean weight of removed breast tissue was 287g. AlloDerm(R) was used to extend subpectoral coverage. Any systemic complication was not reported. Breast complication was developed in 4 cases. Implant removal or change was not experienced. CONCLUSION: Immediate breast reconstruction using Implant is useful methods for certain conditions, when donor tissue is insufficient and breast is non ptotic with round shape. In those cases, extension of muscle coverage using AlloDerm(R) could reduce complications and lead more acceptable results.

Hemodialysis (HD) patients continually exposed to heparin are at risk of developing heparin-induced thrombocytopenia (HIT). However, HIT is very rare in chronic HD patients with end-stage renal disease (ESRD). The authors report the case of a chronic HD patient with ESRD who developed HIT complicated by recurrent thrombocytopenia and significant bleeding episodes. A 67-year-old man with diabetic ESRD on chronic HD suddenly developed recurrent acute bleeding episodes and severe thrombocytopenia (platelet count <1.0x10(3)/uL) 2 months prior to presentation. These bleeding episodes and the thrombocytopenia always occurred 1 week after initiating HD with heparin, and improved within 1 week of discontinuing heparin. HIT was confirmed by ELISA for anti-heparin/platelet factor 4 antibody. HD was conducted successfully and thrombocytopenia did not occur after switching argatroban for heparin. This case report suggests that clinicians must consider HIT in the differential diagnosis of thrombocytopenia during maintenance HD.

Fat necrosis in transverse rectus abdominis musculocutaneous(TRAM) flaps is considered to be primarily affected by blood supply. Unreliability of blood supply in zone II has been claimed for years but no accurate comparison has been reported between fat necrosis in zone II and III. A prospective study about the incidences and extent of fat necrosis in zone II and III was designed, comparing relative vascularity between zone II and III. Immediate breast reconstructions after modified radical mastectomy or skin sparing mastectomy were performed in 150 consecutive patients with unipedicled TRAM flaps and 138 contralateral and 12 ipsilateral rectus muscles were used as pedicles. Twenty-one patients(14 percent) suffered from fat necrosis and 22 fat necroses were diagnosed in total. 17 fat necroses occurred in zone II, 3 in zone III and 2 in zone I. The incidence of fat necrosis in zone II was significantly higher than zone III, which was consistent with previous studies claiming poor vascularity of zone II. Therefore placing zone I and zone III medially and zone II laterally after discarding part of zone II will cause less deformity of reconstructed breast if resection of necrotized tissue is needed.

BACKGROUND AND OBJECTIVES: Calcineurin-dependent transcriptional pathway has recently been implicated in cardiac hypertrophy. Whether calcineurin inhibition can prevent the development of pressure-overload left ventricular hypertrophy (LVH) is still controversial. To elucidate this issue, the effects of calcineurin inhibitors on the prevention of pressure-overload LVH were examined in mice. MATERIALS AND METHODS: Pressure overload was induced by transverse aortic contriction (TAC) in 57 ICR mice. Three different doses of CsA (TAC/CsA group, n=21) and FK506 (TAC/FK group, n=20) were administered subcutaneously from -2 to 14 days after surgery and 16 mice were treated with vehicle (TAC group). Another 60 mice were sham-operated and treated with CsA (CsA group, n=19), FK506 (FK group, n=18) or vehicle (Control group, n=23). RESULTS: Two weeks after TAC, the LV weight-to-body weight (LVW/BW) ratio was not significantly different among the Control, CsA and FK groups although it was greater in the TAC group (4.55+/-0.69 mg/g) than in the Control(2.78+/-0.70 mg/g) and other sham-operated groups (p<0.00005). Low-dose CsA (5 mg/kg/day) or FK506 (0.6 mg/kg/day) injection following TAC did not decrease the LVW/BW ratio. However, intermediate-dose and high-dose CsA (25 and 50 mg/kg/day) or FK506 (2 and 6 mg/kg/day) treatment prevented pressure-overload induced LVH and the degree of LVH inhibition was dose-dependent. Interstitial and/or perivascular fibrosis was remarkably decreased by the administration of intermediate and high doses of calcineurin inhibitors for 2 weeks following TAC. CONCLUSION: Taken together, calcineurin inhibitors, CsA and FK506, attenuated pressure-overload LVH response in a dose-dependent fashion. This data indicates that a calcineurin-dependent signaling pathway is crucial in the development of pressure-overload LVH.
