The pectus carinatum or anterior protrusion of the sternum is a less common than pectus excavatum. It occurs more frequently in boys than girls and associated musculoskeletal abnormalities, spinal scoliosis is most common. Ravitch first reported correction of chondromanubrial prominence in 1952, resecting the multiple deformed costal cartilages and performing a double osteotomy on sternum. We have experienced one case of pectus carinatum and obtained satisfactory postoperative results. The deformity was corrected by the subchondral resection of multiple deformed costal cartilage, bilaterally, with single osteotomy on sternum and fracture of the posterior cortex to correct anterior angulation. Postoperative course was uneventful. We report this case with brief review of the literature.

BACKGROUND/AIMS: It have been reported that operative mortality and morbidity rate rise significantly when emergency cholecystectomy is performed in critically ill patients with acute cholecystitis(AC), and many studies have also concluded that delayed or interval laparoscopic cholecystectomy(LC) in patients with AC demonstrated high conversion rate and complication rate compared with early LC. However, if the acutely inflamed gallbladder(GB) is decompressed by emergent percutaneous gallbladder drainage(PGBD), it may decrease the technical difficulty of LC allowing successful delayed LC or may decrease the wound complication of delayed open cholecystectomy, when the patient is in better condition. The purpose of this retrospective study was to assess the outcome of delayed cholecystectomy focused on LC following PGBD in patients with AC METHODS: A total of 181 patients with AC were divided into PGBD(n= 66) and non-PGBD group(n= 115), and each group were subdivided into PGBD-delayed LC(after 72 hours of admission, n= 32), PGBD-open cholecystectomy(n= 20), non-PGBD-early LC(within 72 hours of admission, n= 40), non- PGBD-delayed LC(n= 17), non PGBD-open cholecystectomy group(n= 58) and others. PGBD group had higher incidence of comorbidity compared with non-PGBD group. Outcomes of cholecystectomy was assessed by conversion rate and morbidity rate(chi2 test), LC time and hospital stay(median test) for LC, and morbidity for open cholecystectomy in PGBD group compared with those of non PGBD group. RESULTS: PGBD promptly relieved of symptom of AC in 94 % of patients and showed 3 % of technical failure and 4.5 % of complication rate. Compared with non PGBD-early and delayed LC group, the PGBD-delayed LC group showed longer LC time(median 110 min vs 82.5, p < 0.05, vs 95 min), a little lower conversion rate(12.5 % vs 22.5 % vs 17.6 %), similar morbidity rate(19% vs 17.5 % vs 29 %) and prolonged total hospital stay(median 12.5 days vs 7 days, p < 0.001, vs 10 days). In open cholecystectomy series, PGBD group showed lower morbidity rate compared with non PGBD group(5% vs 24 %, p < 0.05) CONCLUSION: Unlike to open cholecystectomy series, PGBD did not significantly improve the outcome of LC for AC as assessed by conversion and morbidity rate and hospital stay compared with non PGBD. Thus we can conclude that although PGBD is a safe and effective emergency procedure for AC, it should be limited to higher risk group such as elderly or critically ill patients and to acalculous cholecystitis.

Purpose:
For tonsillar cancer with multiple ipsilateral neck lymph nodes, the safety and efficacy of unilateral radiotherapy (RT) have long been a topic of debate. We performed retrospective analyses of patients having ipsilateral neck lymph nodes treated with unilateral RT in two tertiary referral hospitals.Material and Methods: This study accrued 29 patients who were diagnosed as well-lateralized tonsillar cancer with multiple ipsilateral neck lymph nodes and underwent unilateral RT from March 2000 to March 2020. Patients underwent treatment with one of the following options or a combination of them: induction chemotherapy, surgery, RT, and concurrent chemoradiotherapy. We analyzed the recurrence pattern and survival with special attention to contralateral neck failure. Also, treatment-related toxicities were compared with a 1:1 matched cohort of those who received bilateral RT, using propensity score matching analysis.
Results:
At a median follow-up of 68 months, no contralateral neck failure was observed. Five-year actuarial locoregional recurrence-free survival, distant metastasis-free survival, and overall survival were 85.6%, 91.8%, and 92.7%, respectively. Both the acute and chronic grade 2 xerostomia occurred in 10.3% of the patients. When the toxicity for unilateral RT was compared to that of bilateral RT using a propensity score-matched cohort, a significantly lower rate of acute xerostomia was observed in unilateral RT group (55.1% vs. 82.7%, p=0.002), primarily at grade 2 level (10.3% vs. 51.7%, respectively)
Conclusion
The results of our study suggest that unilateral RT can be safely performed in well-lateralized tonsillar cancer patients with multiple ipsilateral neck lymph nodes.

PURPOSE: To determine whether Ultravist(R) test can enable the surgeon to differentiate complete from partial small bowel obstruction in patients with adhesive small bowel obstruction and whether partial small bowel obstruction can be treated nonoperatively. METHODS: Ninety-two patients who had postoperative small bowel obstructions without any toxic signs underwent Ultravist(R) test. Ultravist(R) (40 ml) mixed with 40 ml of distilled water was administrated either orally or via nasogastric tube to each patient. Serial plain abdominal radiographs were taken 4, 6, and 8 hours later. RESULTS: A total of 58 patients (63%) whose contrast medium reached the colon within the first 8 hours were considered to have partial obstruction (test positive) and were successfully treated with intravenous hydration and nasogastric decompression. The remaining 34 patients (36.9%), in whom the contrast medium failed to reach the colon within the first 8 hours (test negative), were regarded as having complete obstruction. Twenty-three of those patients (67.6%) underwent surgery and the other 11 (32.4%) received conservative treatment. Adhesion bands with complete bowel obstruction were observed in all 23 surgical patients during laparotomy. All the patients with partial bowel obstruction were treated successfully with nonoperative methods. Positive Ultravist(R) test as an indicator for nonoperative treatment had a sensitivity of 84.5%, a specificity of 100%, an accuracy of 88% and a false negative rate of 12%. CONCLUSION: Ultravist(R) can be used to differentiate partial from complete intestinal obstruction. All patients with evidence of Ultravist(R) reaching the colon within 8 hours were treated successfully with non-operative methods.

BACKGROUND: Anti-apoptotic proteins may be involved in tumor development, progression and the response to treatment. Bcl-2 is by far the most studied anti-apoptotic protein. A novel infibitor of apoptosis, designat ed survivin, and the heat shock proteins (HSPs) have recently been found in many human cancers. Immunohistochemical methods were used to determine the expression level of survivin, HSP 70 and bcl-2 in non-small cell lung cancer (NSCLC) to evaluate their clinical significance. METHODS: Tissue array slides were obtained from 99 surgically resected NSCLCs. Immunohistochemical staining was performed by an immuno-peroxidase technique using an avidin-biotinylated horseradish peroxidase complex. Anti-survivin rabbit polyclonal antibodies, anti-HSP70 mouse monoclonal antibodies and anti-bcl-2 mouse monoclonal antibodies were used as the primary antibodies. RESULTS: Positive ataining of survivin was detected in 33.3% of the cases. Survivin positivity is associated with to females and recurrence. A nonstatistically significant trend toward increased survivin expression was observed in non-smokers, and its expression inversely correlated with the number of cigarettes smoked in smokers. HSP70 was detected in 84.8% but this did not correlate with the clinicopathologic characteristics. Bcl-2 was detected in 18.2% and its and its expression correlated to tumor recurrence. No significant difference in the median survival time was noted in a comparison of al cases with survivin expression and those without. There was no association betwwen HSP70 or bcl-2 expression and survival. CONCLUSIONS: Survivin expression was significantly associated with females and tumor recurrence. In addition its expression was inversely associated with the number of cigarettes smoked. However, HSP70 and bcl-2 expression were not associated with the clinical parameters or survival. This suggests that measuring the survivin levels may be useful in identifying patients at high risk for disease recurrence. Therefore, survivin might be a new diagnostic/therapeutic target in cancer.
