ABSTRACT: Nowadays, use of selective nonoperative management has decreased the incidence of nontherapeutic laparotomies in patients with anterior thoracoabdominal stab wounds. The safety of selective nonoperative management was investigated in these patients, not requiring emergency laparotomy.
Patients referred to the Tabriz Imam Reza Hospital with anterior thoracoabdominal stab wounds were studied from August 2008 to 2010. The hemodynamically unstable patients, those with evidence of peritoneal irritation or with organ evisceration, underwent an emergency laparotomy. For other patients, diagnostic peritoneal lavage (DPL) was used and patients with positive results were operated. Patients with negative DPL results underwent serial physical and laboratory examinations.
A total of 204 patients were studied. Sixty-two cases (30.4%) had emergency operations, with 12 (19.4%) cases of nontherapeutic laparotomies. On the basis of DPL results in 142 (69.6%) patients, laparotomy was carried out in another 18 (12.7%) cases with a nontherapeutic result in eight (5.6%) cases. Finally, 124 (60.8%) patients were left for further observation and serial physical and laboratory examinations. Accordingly, five (4%) patients needed delayed laparotomy without any serious complications due to the delayed operation. The length of hospital stay and nontherapeutic laparotomies in our study were lower than mandatory laparotomy management and also, there were no significant complications or mortalities within the 90 days follow-up period.
This study showed that the proposed approach of selective nonoperative management in patients with anterior thoracoabdominal stab wounds is safe, feasible, and probably cost-effective.

ABSTRACT: Increasing evidence shows the importance of young age, estrogen receptor (ER), progesterone receptor (PR) status, and HER-2 expression in patients with breast cancers.
We organized an analytic cross-sectional study of 105 women diagnosed with breast cancer who have been operated on between 2008 to 2010. We evaluated age, size, hormone receptor status, HER-2 and P53 expression as possible indicator of lymph node involvement.
There is a direct correlation between positive progesterone receptor status and being younger than 40 (P < 0.05). Also, compared with older women, young women had tumors that were more likely to be large in size and have higher stages (P < 0.05). Furthermore patients with negative progesterone receptor status were more likely to have HER-2 overexpression (P < 0.05). The differences in propensity to lymph node metastasis between hormone receptor statuses were not statically significant.
Although negative progesterone receptor tumors were more likely to have HER-2 overexpression, it is possible that higher stage and larger size breast cancer in younger women is related to positive progesterone receptor status.

ABSTRACT: The purpose of this study is to report the clinical and functional outcomes of patients, treated between 2004 and 2009, with high-risk popliteal vascular injuries due to compound fractures about the knee.
A retrospective analysis was conducted of prospectively collected data from Tabriz Medical Trauma Center. Our aim was to perform surgical revascularization as soon as the arterial injury was recognized. The mechanism of injury was blunt in the entire cohort of patients, and all of them had bone fractures about the knee. The treatment of arterial injury included vein graft interposition in 39 (63%), primary anastomosis in 20 (32.3%), and lateral repair in 3 (4.8%) patients. The patients were divided into 2 study groups: limb salvage group (group 1) and amputation group (group 2). Subgroup analysis consisted of univariate analysis comparing the 2 groups and multivariate analysis examining the factors associated negatively and positively with the primary endpoint, limb salvage.
In the entire cohort of patients, 60 patients (97%) were male and 2 were female (3%); the mean age was 34.1 years (16-49 years). The overall amputation rate in this study was 37.1% (23 amputations). Significant (P < 0.05) independent factors associated negatively with limb salvage were combined tibia and fibula fracture, concomitant artery and vein injury, ligation of venous injury, and lack of backflow after Fogarty catheter thrombectomy, while repair of popliteal artery and vein injury, when present, was associated with improved early limb salvage. For 40 patients, we adopt a liberal attitude toward open 4-compartment fasciotomy through both medially and laterally placed incisions.
Expeditious recognition of vascular injury, transport to repair, and repair of associated venous injury when possible are necessary to optimize limb salvage. The importance of a high level of suspicion and low threshold for timely amputation has been emphasized when limb salvage was deemed impossible to prevent life-threatening complication. Delays in surgery, extensive soft tissue defect, compound tibia-fibula fracture, and other factors are associated with high amputation rate following popliteal artery injury.

ABSTRACT: Recurrent and complex bilateral inguinal hernias are associated with a high recurrence rate. Giant prosthetic reinforcement of the visceral sac (GPRVS) is popular in America and Europe, but there are no prospective data from Iran.
From 20 March 1995 to 20 March 2003, 234 patients (227 men and 7 women) with 420 inguinal hernias (186 bilateral and 48 unilateral) underwent repair using a large polyester mesh based on Stoppa's preperitoneal technique. Mean age was 60 years (range 25 to 88) and 44.8% had one or more comorbid conditions. In 154 instances, the relapsed hernia had already been operated once or twice for recurrence.
Mean hospital stay after surgery was 2.2 days (range 1-13 days). The mean operative time was 45 minutes (range 30-75 minutes). General complications were one case of upper gastrointestinal bleeding, one case of ileus and one case of atelectasis. Local complications consisted of three local seroma formations. In no instance was postoperative neuralgia, chronic pain or testicular atrophy, mesh infection or death reported. Follow-up was obtained in all patients. The recurrence rate was 0.71% (3 of 420) per inguinal repaired or 0.85% (2 of 234) per patient. Factors predicating a high risk for recurrence included large hernia size (>5 cm), failure of one or more previous repairs (65.8%, 154 of 234), chronic cough and associated lower abdominal hernias.
GPRVS is anatomic, sutureless, tension-free and the absolute weapon to eliminate all type of groin hernias. No other technique produces better results for the repair of recurrent and re-recurrent groin hernias.
