RESUMO
OBJECTIVE: To review standardized Nuss correction of pectus excavatum and vacuum bell treatment over the last 10 years. SUMMARY OF BACKGROUND DATA: In 2010, we reported 21 years of the Nuss procedure in 1215 patients. METHODS: Over the last 10 years, 2008-2018, we evaluated 1885 pectus excavatum patients. Surgery was indicated for well-defined objective criteria. A consistent operation was performed by 8 surgeons in 1034 patients, median 15 years, (range 6-46); 996 were primary, and 38 redo operations. Surgical patients' mean computed tomography index was 5.46. Mitral valve prolapse was present in 5.4%, Marfan syndrome in 1.1% and scoliosis in 29%. Vacuum bell treatment was introduced for 218 patients who did not meet surgical criteria or were averse to surgery. RESULTS: At primary operation, 1 bar was placed in 49.8%; 2 bars, 49.4%; and 3 bars, 0.7%. There were no deaths. Cardiac perforation occurred in 1 patient who had undergone previous cardiac surgery. Paraplegia after epidural catheter occurred once. Reoperation for bar displacement occurred in 1.8%, hemothorax in 0.3%, and wound infection in 2.9%; 1.4% required surgical drainage. Allergy to stainless steel was identified in 13.7%. A good anatomic outcome was always achieved at bar removal. Recurrence requiring reoperation occurred in 3 primary surgical patients. Two patients developed carinate overcorrection requiring reoperation. Vacuum bell treatment produced better results in younger and less severe cases. CONCLUSIONS: A standardized Nuss procedure was performed by multiple surgeons in 1034 patients with good overall safety and results in primary repairs. Vacuum bell treatment is useful.

BACKGROUND/PURPOSE: Evaluate the safety of sternal elevation (SE) used selectively before creating the substernal tunnel during the Nuss procedure. METHODS: An IRB-approved (01-05-EX-0175-HOSP), single institution, retrospective review was performed (1/1/1997-11/20/2017). Primary and secondary Nuss repairs (i.e., previous Nuss, Ravitch, thoracotomy, or sternotomy) are included. SE use, cardiac injuries, and pectus bar infections are reported. Chi square and Fisher's exact test (FE) were used (critical pâ¯<â¯.05). RESULTS: 2037 patients [(80% male; mean age 15.2â¯years (SDâ¯=â¯4.4, range 3-46); mean Haller index (HI) 5.3 (SDâ¯=â¯5.7, range 1.73-201)] underwent Nuss repair. SE was used before creating the substernal tunnel in 171 (8.4%): 160 (8.2%) of 1949 primary and 11 (12.5%) of 88 secondary repairs. SE use increased significantly [χ2(2)â¯=â¯118.93; pâ¯<â¯.001] over time and with increasing HI [χ2(3)â¯=â¯59.9; pâ¯<â¯.001]. No cardiac injuries occurred in primary repairs but two occurred in patients with previous sternotomy. Infection rates were not different with (2.9%) or without SE (1.8%) [χ2(1) =1.14; pâ¯=â¯.285] and not higher with off-label VB (1.5%) versus other SE techniques (3.8%) [FE, pâ¯=â¯.65)]. CONCLUSION: Selective use of sternal elevation before substernal dissection during the Nuss procedure is safe but may not prevent cardiac injuries in patients with previous sternotomy. Infection rates were not increased with SE. TYPE OF STUDY: Retrospective review. LEVEL OF EVIDENCE: IV.

In this report, the authors investigate and discuss a galactocele that developed in the breast of a 5-month-old male. Based on the histological and immunohistochemical findings, they suggest that the rare and intriguing process that is exclusively observed in males in the absence of any detectable hormonal stimulation at time of investigation could represent a developmental anomaly possibly promoted by an obstructive phenomenon involving a defect of hollowing of some primary epidermal buds, the precursors of the mammary ducts.

BACKGROUND/PURPOSE: The major side effect of total parenteral nutrition is liver injury leading to liver failure. This study was designed to assess specific growth factors in modulating the hepatic response in an ANIT-induced liver-injury model. METHODS: Sprague-Dawley rats were divided into four groups: control (n = 5), liver-injury control (alpha-naphthylisothiocyanate [ANIT], 100 mg/kg, n = 8), ANIT + epidermal growth factor (EGF, 150 mug/kg per day, n = 10), and ANIT + hepatocyte growth factor (HGF, 250 mug/kg per day, n = 9). Rats were given intraperitoneal injections of saline (control) or ANIT and implantation of an osmotic mini-pump for 7 days of continuous intravenous saline (liver injury control), EGF, or HGF. Seven and 14 days later, liver biopsies were obtained and evaluated for interleukin (IL)-6 and tumor necrosis factor alpha expression by immunofluorescent staining, and for apoptosis, by the terminal transferase dUTP nick end labeling (TUNEL) technique. All animals were euthanized at 14 days. RESULTS: Epidermal growth factor (P < .025) and HGF (P < .001) groups induced less IL-6 expression at day 14 compared to liver-injury controls. In addition, the interval decrease in IL-6 expression between days 7 and 14 was greater in EGF (P < .001) and HGF (P < .001) groups compared to liver-injury controls. At day 14, HGF also demonstrated decreased tumor necrosis factor alpha expression (P < .005). Apoptotic activity was significantly less for the EGF (P < .011) and HGF (P < .0012) groups. CONCLUSION: Epidermal growth factor and HGF modulated the hepatic inflammatory response and apoptotic index in this established liver-injury model and may diminish or prevent liver damage in patients with total parenteral nutrition-induced liver injury.

Ovarian sex cord stromal tumor (OSCST), sclerosing type, is an extremely rare ovarian tumor. Sex hormone production by OSCST can result in isosexual or heterosexual precocious puberty in younger patients. We present a case of a 7-month-old female infant found to have a sclerosing-type OSCST that presented with vaginal bleeding and very prominent vellus hair at the mons pubis. This represents the youngest patient reported in the literature with this subset of OSCST.
