In the last hundred years, the science of fracture repair has significantly changed. Management has moved from a simple metabolic and hormonal concept of bone regeneration to an inflammatory concept and now to a more complicated immunological description. Fracture repair has been considered age-dependent and related to diabetes, nutrition, hormone connection, autoimmune diseases, rheumatic arthritis, and nicotine. Recently a new branch of medicine, osteoimmunology, which deals with the mechanism of fracture repair, has been introduced.

Hiatal hernia is defined as a protrusion of abdominal contents through the hiatal foramen into the thoracic cavity. Etiology is presumed to be a congenital malformation, trauma, or iatrogenic like prior surgical dissection of the hiatus during surgery for esophageal or gastric etiology. Age, sex, hormonal changes, body habitus (i.e., kyphosis, scoliosis), and increased body weight are key risk factors. Most hiatal hernias are asymptomatic and discovered incidentally. Surgical repair of hiatal hernia is indicated in symptomatic patients with dysphagia, weight loss, respiratory symptoms such as aspirations, and recurrent pneumonia events [1]. Complications arising from laparoscopic repair of hiatal hernia are generally minor and do not typically necessitate surgical intervention. Major complications include pneumothorax, splenic laceration, esophageal rupture, and pericardial injury. Other complications include recurrence of hernia, vagal nerve injury, gastroesophageal reflux disease, and gastroparesis. The utilization of mesh in repair procedures introduces additional complications such as mesh migration and mesh infection. Previously reported recurrence rates following the repair of a hiatal hernia with mesh range from 10–30%. In this case communications, we presented a case involving the early recognition and treatment of postoperative cardiac tamponade.

Background: Diagnosing occult stress urinary incontinence (OSUI) prior to surgical intervention for pelvic organ prolapse (POP) repair may allow for adding an anti-incontinence procedure and thus prevent postoperative SUI.

Objectives: To compare preoperative detection rates for OSUI by either a multichannel urodynamic investigation or by a plain pelvic examination.

Methods: We retrospectively evaluated the medical charts of all women who underwent urodynamic investigation prior to surgical repair of advanced POP at our institution between 1 January 2006 and 31 December 2012.

Results: In total, 720 women underwent surgical POP repair during the study period, of whom 54 (7.5%) were diagnosed with OSUI preoperatively. Of these patients, 54 (100%) were detected by multichannel urodynamic investigation while only 27 (50%) were detected by a plain pelvic examination (P = 0.001). Bladder fullness during the pelvic examination was associated with higher detection rates for OSUI (P = 0.001). Women with OSUI who underwent concomitant tension-free vaginal tape and POP repair procedures did not develop de novo SUI or obstructive voiding symptoms (OVS) postoperatively.

Conclusions: Preoperative multichannel urodynamic investigation has significantly higher detection rates for OSUI than a plain pelvic examination. Utilizing this modality resulted in no cases of de novo SUI or OVS postoperatively.

Background: Upper eyelid blepharoplasty surgery is one of the most common plastic surgeries. Khat is used topically to reduce tissue edema.

Objectives: To evaluate the effect of topical khat administration after eyelid surgery on postoperative healing.

Methods: Our prospective comparative study included 24 patients who underwent upper eyelid blepharoplasty or ptosis surgery between 2019 and 2020. Patients were randomly assigned to 48 hours of cold dressing with frozen khat leaves and frozen peas dressing (common practice). Postoperative photographs of the eyes were evaluated for the degree of ecchymosis and edema on postoperative days (PODs) 1, 3, and 7 by three blinded observers. Measures included tissue swelling and hemorrhage on PODs 1, 3, and 7.

Results: The mean age of the cohort was 67 ± 7 years; 17 females (71%). Khat application was associated with lower postoperative ecchymosis at each time point. Females had lower levels of postoperative ecchymosis on POD 7 (P = 0.07). Eyelid edema was more pronounced in the khat group on PODs 1 and 3, but this was reversed on POD 7. There was good agreement among all three observers in grading ecchymosis and edema (P < 0.001).

Conclusions: The use of khat was associated with less tissue ecchymosis after oculoplastic surgery, although this was not statistically significant even following sub-population analysis. The outcome can be attributed to the active ingredients of cathinone and cathine, which cause vasoconstriction and lipolysis, and to the anti-inflammatory and anti-oxidative flavonoids and phenolic compounds. These encouraging preliminary findings warrant additional studies on a biochemical/cellular level.

Background: Cancer patients with heart failure (HF) and severe mitral regurgitation (MR) are often considered to be at risk for surgical mitral valve repair/replacement. Severe MR inducing symptomatic HF may prevent delivery of potentially cardiotoxic chemotherapy and complicate fluid management with other cancer treatments.

Objectives: To evaluate the outcome of percutaneous mitral valve repair (PMVR) in oncology patients with HF and significant MR.

Methods: Our study comprised 145 patients who underwent PMVR, MitraClip, at Hadassah Medical Center between August 2015 and September 2019, including 28 patients who had active or history of cancer. Data from 28 cancer patients were compared to 117 no-cancer patients from the cohort.

Results: There was no significant difference in the mean age of cancer patients and no-cancer patients (76 vs. 80 years, P = 0.16); 67% of the patients had secondary (functional) MR. Among cancer patients, 21 had solid tumor and 7 had hematologic malignancies. Nine patients (32%) had active malignancy at the time of PMVR. The mean short-term risk score of the patients was similar in the two groups, as were both 30-day and 1-year mortality rates (7% vs. 4%, P = 0.52) and (29% vs. 16%, P = 0.13), respectively.

Conclusion: PMVR in cancer patients is associated with similar 30-day and 1-year survival rate compared with patients without cancer. PMVR should be considered for cancer patients presenting with HF and severe MR and despite their malignancy. This approach may allow cancer patients to safely receive planned oncological treatment

Background: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) is associated with decreased perioperative morbidity and mortality.

Objectives: To report the outcomes of EVAR among patients older than 80 years of age.

Methods: In this retrospective study, we reviewed patients older than 80 years of age who underwent elective EVAR at our institution between 2007 and 2017. The demographics, perioperative morbidity and mortality, and long-term results are reported.

Results: During the study period, 444 patients underwent elective EVAR for AAAs. Among them 128 patients (29%) were > 80 years of age. Mean age was 84 ± 3.4 (range 80–96) years, and 110 patients (86%) were male. The EVAR was technically successful in 127 patients (99%) and there were intraoperative mortalities. Within 30 days of the surgery, nine patients (7%) died. Major and minor adverse events occurred in 26 (20%) and 59 (46%) patients, respectively. Factors associated with increased risk of perioperative morbidity and mortality included chronic kidney disease, peripheral artery disease, and the existence of three or more co-morbidities.

Conclusions: EVAR in the elderly can be performed with a high rate of success; however, it is associated with a substantial rate of morbidity and mortality, particularly when patients present with multiple co-morbidities. When performing EVAR in this population group, the risk of rupture must be considered opposed to the life expectancy of these patients and the risk of perioperative morbidity and mortality.

Background: Evaluation of mismatch repair (MMR) deficiency is conducted via immunohistochemistry or by microsatellite instability (MSI) analysis. Heterogeneous immunohistochemistry staining for MMR proteins may show different patterns; however, according to current guidelines, all of those patterns should be interpreted as MMR proficient. This conclusion might lead to false negative results because although most cases of heterogeneity stem from technical factors and biological variability, other types of heterogeneity represent true MMR deficiency.

Objectives: To identify a unique heterogeneity pattern that is associated with true MMR loss.

Methods: We analyzed 145 cases of colorectal carcinoma. Immunohistochemistry staining for MLH1, PMS2, MSH2, and MSH6 were performed. We defined geographic heterogeneity as areas of tumor nuclear staining adjacent to areas of loss of tumor nuclear staining with intact staining in the surrounding stroma. All cases were evaluated for the presence of geographic heterogeneity. In addition, 24 cases were also evaluated by MSI testing.

Results: Of the 145 cases, 24 (16.5%) were MMR deficient. Of the 24 cases for which MSI analysis was also available, 10 cases (41.7%) demonstrated biological heterogeneity, 5 (20.8%) demonstrated technical heterogeneity, and 2 (8.3%) demonstrated geographic heterogeneity. Only the two cases with geographic heterogeneity were MSI-high via MSI analysis. In addition, a germline mutation in MSH-6 was identified in one of these cases.

Conclusions: Geographic heterogeneity may raise a suspicion for a MMR-deficient case, which should be further analyzed using additional methodologies such as MSI analysis.

Background: Hysterectomy is common in the management of symptomatic uterine prolapse. Vaginal wall repair is often necessary, for which vaginal mesh remains a popular option.

Objectives: To evaluate the risk of mesh erosion following mesh-augmented vaginal prolapse repair, with or without concomitant vaginal hysterectomy.

Methods: This retrospective cohort comprised 70 women who underwent vaginal mesh-augmented pelvic organ prolapse repair from 2007 to 2010. Of the participants, 36 (51.4%) had a vaginal hysterectomy concomitant to the anterior and/or posterior vaginal mesh repair (hysterectomy group) and 34 (48.6%) underwent mesh repair without vaginal hysterectomy (no hysterectomy group).

Results: There were no inter-group differences in age, parity, menopausal state, hormonal use, or presenting symptoms. Previous prolapse repair surgery was much more common in the no hysterectomy group (29.4% vs. 5.5%, P = 0.01). Eleven patients (32.3%) in the no hysterectomy group had previously undergone hysterectomy. Anterior mesh repair was performed in 77.7% and 67.6% of hysterectomy and no hysterectomy patients, respectively. Posterior mesh repair was performed in 27.7% and 44.1%, respectively. One patient in the hysterectomy group underwent immediate removal of mesh due to infection. Surgically treated mesh erosion (limited local excision) occurred in three patients (8.3%) in the hysterectomy group (3, 16, and 18 months following surgery) and in two patients (5.8%) in the no hysterectomy group at 6 months following surgery (P = 0.67).

Conclusions: Vaginal mesh-augmentation concomitant with vaginal hysterectomy for pelvic organ prolapse repair does not carry an increased risk of erosion.

Background: Unicuspid and bicuspid aortic valve (BAV) are congenital cardiac anomalies associated with valvular dysfunction and aortopathies occurring at a young age.

Objectives: To evaluate our experience with aortic valve repair (AVr) in patients with bicuspid or unicuspid aortic valves.

Methods: Eighty patients with BAV or unicuspid aortic valve (UAV) underwent AVr. Mean patient age was 42 ± 14 years and 94% were male. Surgical technique included: aortic root replacement with or without cusp repair in 43 patients (53%), replacement of the ascending aorta at the height of the sino-tubular junction with or without cusp repair in 15 patients (19%), and isolated cusp repair in 22 patients (28%).

Results: The anatomical structure of the aortic valve was bicuspid in 68 (85%) and unicuspid in 12 patients (15%). Survival rate was 100% at 5 years of follow-up. Eleven patients (13.7%) underwent reoperation, 8 of whom presented with recurrent symptomatic aortic insufficiency (AI). Late echocardiography in the remaining 69 patients revealed mild AI in 63 patients, moderate recurrent AI in 4, and severe recurrent AI in 2. Relief from recurrent severe AI or reoperations was significantly lower in patients who underwent cusp repair compared with those who did not (P = 0.05). Furthermore, the use of pericardial patch augmentation for the repair was a predictor for recurrence (P = 0.05).

Conclusions: AVr in patients with BAV or UAV is a safe procedure with low morbidity and mortality rates. The use of a pericardial patch augmentation was associated with higher repair failure.

Background: One of the most alarming ocular injury trends in recent years has been the proliferation of paintball guns and the proportional increase in the number of ocular eye injuries caused by paintballs.

Objectives: To describe five cases of paintball eye injuries that resulted in loss of functional vision in four of them.

Methods: We conducted a retrospective interventional case series of the clinical course of five patients with paintball eye injuries treated in the ophthalmology departments of two medical centers. 

Results: Five young males were evaluated for paintball injuries caused by blunt trauma. There was one case of full-thickness laceration (globe rupture). Four patients required one to five surgical interventions: three of these involved the removal of traumatic cataract including two eyes with significant zonular dehiscence treated by lens capsule conservation using anchoring devices, one retinal surgery and two glaucoma filtration surgeries. However, final visual outcome was not favorable due to irreversible retinal damage.

Conclusions: Paintball trauma often results in significant ocular injury and loss of functional vision despite successful surgical interventions. Most injuries are easily preventable and occur in under-supervised settings. Improved safety measures, strict regulation enforcement and appropriate public education could prevent such serious damage.
