2.Characteristics of pantaloon inguinal hernia and evaluation of added laparoscopic iliopubic tract repair to transabdominal preperitoneal hernioplasty: a retrospective observational study
Annals of Surgical Treatment and Research 2024;106(6):361-368
Purpose:
Pantaloon hernia (PH), defined as concurrent ipsilateral direct and indirect inguinal hernias, is known for its high postoperative recurrence rate. This study retrospectively investigated the characteristics of PHs and evaluated the safety and efficacy of incorporating laparoscopic iliopubic tract repair (IPTR) into transabdominal preperitoneal (TAPP) hernioplasty.
Methods:
A total of 3,355 patients who underwent TAPP hernioplasty for groin hernias between October 2014 and December 2021 were analyzed. These patients were divided into 2 groups: PH (97 patients) and non-PH (3,258 patients). The PH group was further subdivided based on the surgical technique used: TAPP hernioplasty without IPTR (TAPP group, 39 patients) and TAPP hernioplasty with IPTR for defect closure (TAPP + IPTR group, 58 patients).
Results:
The study included 93 male and 4 female patients with PH. Patients with PH were generally older and predominantly male compared to the non-PH group. The recurrence rate in the PH group was notably higher than in the non-PH group (2.1% [2 of 97] vs. 0.2% [6 of 3,258], respectively; P = 0.007). Among the PH group, reoperations were more frequent in the TAPP group compared to the TAPP + IPTR group (10.3% [4 of 39] vs. 0% [0 of 58], respectively; P = 0.048). The reasons for reoperation in the PH group included recurrences (2 patients), mesh bulge (1 patient), and chronic seroma (1 patient).
Conclusion
TAPP + IPTR hernioplasty is an acceptable approach in PH treatment, reducing reoperation.

Human assisted reproductive technology programs have been being developed marvelously during this decade. However, implantation rates following embryo replacement remain low, regardless of increased fertilization rates by ICSI. One proposed possibility limiting the successful implantation is an impaired hatching caused by suboptimal culture conditions. As to improve the hatching potential of blastocysts, assisted hatching by an artificial alteration of zona pellucida(ZP) have been done in many laboratories using the various methods. We tried to investigate whether the supplementation of proteases into culture media has any effect on development, zona structure, and/or hatching of mouse embryos. Supplementation of either pronase E(PE) or proteinase K(PK) in culture media did not affect development up to blastocyst but significantly increased hatching rate. And we observed the alteration of ultrastructure and casein binding properties of ZP in mouse embryos. Also we investigated the effects of protease on development of human embryos and pregnancy rates in human ART program. From July 1994 to December 1996, 792 cycles(for study I) and 1095 cycles(for study II) undergoing the IVF-ET program in MizMedi Hospital were randomly selected for BAH. The concentrations of proteases used in this study were 1microgram/ml PE, 0.1microgram/ml PK and 1microgram/mlPE+0.1microgram/ml PK in HTF with 0.5% human serum albumin(HSA), and in vitro fertilized embryos were cultured for 24 hours. We analyzed the efficiency and stability of biochemical assisted hatching(BAH) according to the clinical profiles of patients and fertilization methods. After cultured in HTF with proteases for 24 hours of human embryos, the thinning in zona pellucida of embryos was observed but its development was not disturbed. Also, clinical pregnancy rates were higher in the PE, PK and PE+PK groups than the control group without proteases(36.0%(32/89), 35.3%(36/102), 35.1%(39/111) vs. 25.5%(125/490), p<0.05). The live birth rate in the PE, PK and PE+PK groups were increased than control, and the abortion rate were not different. They were showed a effect and safety of proteases treatment in human embryos. We selected PE as BAH for study II because of slightly better embryonic morphology and pregnancy rate. In patients over 35 years old, clinical pregnancy rates of the BAH group was higher than that of the control group(31.4%(58/185) vs. 22.2%(51/230); p<0.05). And in the cases with few oocytes retrieval, or less than 3 cycles of IVF-ET, clinical pregnancy rates of the BAH group was significantly higher than that of the control group(36.8%(86/234) vs. 27.2%(93/342), p<0.05; 36.8%(148/402) vs. 29.9%(168/562), p<0.05). In BAH groups, the clinical pregnancy rate was similar between conventional IVF and ICSI group. From above results, it is suggested that improved hatching by protease treatment is due to physiological alteration of ZP structure, giving rise to the similar hatching process to that in vivo. We suggest that BAH using protease is a simple, safe and economic technique compared to the other known assisted hatching techniques in human ART program.

BACKGROUND: Even though there were developments in various treatment techniques for acute arterial occlusion this disease still has high rate of mortalities and limb amputations. We investigated the combined diseases symptoms location of occlusion type of treatment complication and prognosis in our patients. MATERIAL AND METHODS: This study recruited 48 patients (42 men, 6 women, mean age 57.7 years) who received the operation from January 1995 toDecember 1998. We investigated the post-operation course via medical record review or telephone interview with patients or their family members. RESULT: The most common combined diseases were atherosclerosis in 30 patients. other diseases were 17 diabetes mellitus 16 hypertension and 12 atrial firillation. Pain and clod sensation were noticed in all patients paresthesia in 5 patients fibrillation. Pain and cold sensation were noticed in all patients paresthesia in 5 patients and lower extremity paralysis in 11 patients. In 29 patients the time interval from the onset of symptom to admission was over 72 hours and 15 patients were admitted within 24 hours. The distribution of arterial occlusion location was at 28 femoral arteries 14 popliteal arteries and 6 iliac arteries. All the patients were received embolectomy and 5 patients were received additional bypass grafting. Postoperative complications were 12 reocclusions. 6 compartment syndromes 6 skin necrosis and 2 acute renal failure. The mortality rate was 16.7% (8/48) and the amputation rate was 25%. CONCLUSION: This study revealed 25% reocclusion 25% limb amputation and 16.7% mortaliyt. To improve the prognosis of acute lower extrements arterial occlusion early diagnosis and understand the underlying diseases prompt treatment and operation additional operation including interventional radiologic examination and thorough postoperative care would be appreciated.

9.Dose-response meta-analysis: application and practice using the R software
Epidemiology and Health 2019;41(1):e2019006-
The objective of this study was to describe the general approaches of dose-response meta-analysis (DRMA) available for the quantitative synthesis of data using the R software. We conducted a DRMA using two types of data, the difference of means in continuous data and the odds ratio in binary data. The package commands of the R software were “doseresmeta” for the overall effect sizes that were separated into a linear model, quadratic model, and restricted cubic split model for better understanding. The effect sizes according to the dose and a test for linearity were demonstrated and interpreted by analyzing one-stage and two-stage DRMA. The authors examined several flexible models of exposure to pool study-specific trends and made a graphical presentation of the dose-response trend. This study focused on practical methods of DRMA rather than theoretical concepts for researchers who did not major in statistics. The authors hope that this study will help many researchers use the R software to perform DRMAs more easily, and that related research will be pursued.
