Uterine rupture is specified as a complete laceration of the uterine wall, including its serosa, leading to a connection between the endometrial and peritoneal chambers. It can occur in any stage of pregnancy and is considered a severe and perhaps fatal complication. A 35-year-old woman at 9 weeks of gestation with a medical history of five prior cesarean sections presented with lower abdominal pain that had lasted for 5 hr. We detected small amounts of free fluid in the Douglas pouch using ultrasound. Subsequently, a laparotomy revealed a cesarean scar dehiscence from a non-cesarean scar pregnancy. Patients who experience a uterine rupture may have vague symptoms, severe abdominal discomfort, abnormal uterine bleeding, and severe hemorrhagic shock, depending on their gestational age. Ultrasound imaging can be used to diagnose this fatal condition in addition to laparoscopy to immediately identify and treat the issue in urgent cases.

AIMS
Closure of congenital body wall defects in children can be a challenging task for the pediatric Surgeon. Biological prosthesis has been increasingly used for high-risk wound closure in adult patients with excellent outcomes and use in the pediatric population has also been reported. Here, we aim to study the outcome of abdominal wound repair with a tissue-engineered acellular bovine pericardial patch.
METHODS
Over a period of 21 months, a total of 15 children had undergone abdominal wound repair with bioprostheses, i.e., bovine pericardial patch at our institute. Patient demographics, cause of defect, an indication of patch use, rate of infection, postoperative recovery, recurrence, and outcome were studied.
RESULTS
A total of 15 patients underwent abdominal wall closure with acellular bovine pericardial patch. Nine out of 15 patients were neonates, of whom five had gastroschisis, two had a congenital diaphragmatic hernia, and two had ruptured omphalocele major. Of the rest 6 patients, 2 were patients of bladder exstrophy, 2 were older children of congenital diaphragmatic hernia with incisional hernias, and 2 were older children with omphalocele major. Out of the five patients with gastroschisis, two died during the early postoperative period due to sepsis. The wound healed in the rest 13 patients with mild skin dehiscence in two patients. Only one child had a recurrence.
CONCLUSION
Reconstruction with acellular bovine pericardial patch is a viable option in children with high-risk abdominal wounds as it allows tensionless repair with excellent healing and minimal complications. Recurrence, if any, may disappear with time as remodeling of the prosthesis occurs along with the growth of the body wall of the child.

BACKGROUND
Breast reconstruction following mastectomy is a critical component of breast cancer treatment, aimed at improving patient quality of life. However, the management is fraught with potential complications, including skin necrosis and wound dehiscence, which can significantly impact clinical outcomes.
CASE PRESENTATION
We report a unique case of a patient, 5 years post-breast reconstruction following mastectomy and radiation therapy, who developed severe skin necrosis and wound dehiscence due to a brown recluse spider bite on the reconstructed breast. The complication necessitated the debridement of skin, removal of the implant, and further reconstruction with a latissimus flap.
DISCUSSION
The case underscores the unusual etiology of spider bite-induced necrosis in breast reconstruction and highlights the challenges and strategic considerations in managing such complications. Upon presentation, the patient's affected breast area showed signs of extensive necrosis and wound dehiscence, directly attributed to the cytotoxic effects of the brown recluse spider's venom. The venom's pathophysiology involves a complex cascade, leading to local and systemic effects. The local effects, marked by dermonecrosis, com- promised skin integrity in this instance. Systemic effects, not observed in this patient but potentially severe, can include hemolysis, coagulopathy, and acute renal failure, highlighting the seriousness of brown recluse spider bites.
CONCLUSION
In conclusion, this case illustrates the complexities of managing breast reconstruction post-mastectomy complications, particularly those caused by external factors such as brown recluse spider bites. It highlights the need for meticulous attention to unusual etiologies of necrosis and dehiscence, demonstrating the importance of adaptable surgical strategies and a thorough understanding of venom pathophysiology in ensuring successful patient outcomes.

Journal of Maxillofacial and Oral... Jun 2024To assess the efficacy of Herbert cannulated bone screw versus Lag screw in fixation of oblique mandibular fractures.
PURPOSE
To assess the efficacy of Herbert cannulated bone screw versus Lag screw in fixation of oblique mandibular fractures.
MATERIALS AND METHOD
Study composed of two groups of 20 patients each and descriptive statistics were performed with value set at 0.05 with confidence interval of 95%. Group A was treated by Titanium Lag screws; while, Group B was treated by Titanium Herbert Cannulated Bone Screws for the management of oblique mandibular fractures. Postoperatively, all the patients were evaluated clinically and radiographically by recording the incidence of complications (if any) which included trismus, neurosensory deficit, swelling, infection. Parameters such as occlusal discrepancy, rigid fixation (interfragmentary gap) and duration of surgery were also recorded for all the patients.
RESULTS
All the patients were followed for a period of three months. Difference in mouth opening was found to be statistically significant during 1st month follow-up (-Value-0.002). Postoperatively, the mean interfragmentary gap in Group A was significantly more than Group B (-Value-0.000). Other parameters like neurosensory deficits, occlusal discrepancies, chewing efficiency, stability of fractured fragments and post-operative complications in terms of swelling, hardware exposure, radiolucency surrounding screw and wound dehiscence did not show any statistically significant difference.
CONCLUSION
The obtained results showed that both lag screws and Herbert cannulated bone screws fulfill the treatment goals of adequate reduction, fixation and stabilization of oblique mandibular fractures. Herbert screws have shown to have better results in terms of interfragmentary gap reduction as compared to lag screws.

Background Abdominal wound dehiscence, a serious postoperative issue, remains a significant concern for surgeons due to its potential to increase patient mortality and morbidity. Disruption can occur at any point after surgery, sparking debate over the optimal closure method for midline vertical abdominal wounds. Therefore, it's crucial to determine the safest approach. Our randomized clinical trial is planned to compare the risk of a burst abdomen associated with the Hughes abdominal closure technique to that of continuous abdominal closure. Methods All patients >18 years scheduled for emergency midline laparotomy were randomly assigned into two groups using computer-generated random numbers: Group A underwent Hughes repair (12 patients) and Group B underwent continuous closure (17 patients). Preoperative data, including patient demographics, and postoperative outcomes, such as time for rectus closure, wound dehiscence, surgical site infection (SSI), and length of hospital stay, were documented for analysis. Results The study found that the average patient age was 37.89 years, with more males than females. Both groups had an equal distribution of co-morbidities (p = 0.468), but none of these factors were statistically significant. Burst abdomen occurred in 25% of group A and 41.1% of group B (p = 0.367, not significant). Incisional hernia was absent in both groups. Surgical site infection (p = 0.119) and respiratory complications (p = 0.16) were not statistically significant between groups. However, in group A, the regressive analysis showed significant associations between burst abdomen, surgical site infection (p = 0.018), and respiratory complications (p = 0.007), while in group B, these associations were not significant (p = 0.252 for SSI and p = 0.906 for respiratory complications). Conclusion The occurrence of burst abdomen and closure time differences between continuous and Hughes techniques were not significant. The Hughes technique was quicker to learn (32 vs. 22 minutes). Burst abdomen was more common in continuous closure (group A: 25% vs. group B: 41%), favoring the Hughes technique. Factors like age, gender, and others didn't significantly impact the burst abdomen in either group.

Conventional wound approximation devices, including sutures, staples, and glues, are widely used but risk of wound dehiscence, local infection, and scarring can be exacerbated in these approaches, including in diabetic and obese individuals. This study reports the efficacy and quality of tissue repair upon photothermal sealing of full-thickness incisional skin wounds using silk fibroin-based laser-activated sealants (LASEs) containing copper chloride salt (Cu-LASE) or silver nanoprisms (AgNPr-LASE), which absorb and convert near-infrared (NIR) laser energy to heat. LASE application results in rapid and effective skin sealing in healthy, immunodeficient, as well as diabetic and obese mice. Although lower recovery of epidermal structure and function was seen with AgNPr-LASE sealing, likely because of the hyperthermia induced by laser and presence of this material in the wound space, this approach resulted in higher enhancement in recovery of skin biomechanical strength compared to sutures and Cu-LASEs in diabetic, obese mice. Histological and immunohistochemical analyses revealed that AgNPr-LASEs resulted in significantly lower neutrophil migration to the wound compared to Cu-LASEs and sutures, indicating a more muted inflammatory response. Cu-LASEs resulted in local tissue toxicity likely because of effects of copper ions as manifested in the form of a significant epidermal gap and a 'depletion zone', which was a region devoid of viable cells proximal to the wound. Compared to sutures, LASE-mediated sealing, in later stages of healing, resulted in increased angiogenesis and diminished myofibroblast activation, which can be indicative of lower scarring. AgNPr-LASE loaded with vancomycin, an antibiotic drug, significantly lowered methicillin-resistant Staphylococcus aureus (MRSA) load in a pathogen challenge model in diabetic and obese mice and also reduced post-infection inflammation of tissue compared to antibacterial sutures. Taken together, these attributes indicate that AgNPr-LASE demonstrated a more balanced quality of tissue sealing and repair in diabetic and obese mice and can be used for combating local infections, that can result in poor healing in these individuals.

BACKGROUND
The evolutionary success of flowering plants is associated with the vast diversity of their reproductive structures. Despite recent progress in understanding angiosperm-wide trends of floral structure and evolution, a synthetic view of the diversity in seed form and function across angiosperms is lacking.
SCOPE
Here we present a roadmap to synthesise the diversity of seed forms in extant angiosperms, relying on the morphospace concept, i.e. a mathematical representation which relates multiple traits and describes the realised morphologies. We provide recommendations on how to broaden the range of measurable traits beyond mass, by using key morphological traits representative of the embryo, endosperm, and seed coat but also fruit attributes (e.g., dehiscence, fleshiness). These key traits were used to construct and analyse a morphospace to detect evolutionary trends and gain insight into how morphological traits relate to seed functions. Finally, we outline challenges and future research directions, combining the morphospace with macroevolutionary comparative methods to underline the drivers that gave rise to the diversity of observed seed forms.
CONCLUSIONS
We conclude that this multidimensional approach has the potential, although still untapped, to improve our understanding of covariation among reproductive traits, and further elucidate angiosperm reproductive biology as a whole.

Four patients with rectal cancer required reconstruction of a defect of the posterior vaginal wall. All patients received neoadjuvant (chemo)radiotherapy, followed by an en bloc (abdomino)perineal resection of the rectum and posterior vaginal wall. The extent of the vaginal defect necessitated closure using a tissue flap with skin island. The gluteal turnover flap was used for this purpose as an alternative to conventional more invasive myocutaneous flaps (gracilis, gluteus, or rectus abdominis). The gluteal turnover flap was created through a curved incision at a maximum width of 2.5 cm from the edge of the perineal wound, thereby creating a half-moon shape skin island. The subcutaneous fat was dissected toward the gluteal muscle, and the gluteal fascia was incised. Thereafter, the flap was rotated into the defect and the skin island was sutured into the vaginal wall defect. The contralateral subcutaneous fat was mobilized for perineal closure in the midline, after which no donor site was visible.The duration of surgery varied from 77 to 392 min, and the hospital stay ranged between 3 and 16 days. A perineal wound dehiscence occurred in two patients, requiring an additional VY gluteal plasty in one patient. Complete vaginal and perineal wound healing was achieved in all patients. The gluteal turnover flap is a promising least invasive technique to reconstruct posterior vaginal wall defects after abdominoperineal resection for rectal cancer.

International Ophthalmology Jun 2024To clarify the characteristics of intraocular lens (IOL) dislocation requiring IOL suture or intraocular scleral fixation.
PURPOSE
To clarify the characteristics of intraocular lens (IOL) dislocation requiring IOL suture or intraocular scleral fixation.
METHODS
This retrospective consecutive case series included 21 eyes (21 patients) who required sutured or sutureless intrascleral IOL fixation following IOL extraction owing to IOL dislocation at the outpatient clinic in the Department of Ophthalmology, Saitama Red Cross Hospital, Japan, between January and December 2019. Medical records were retrospectively reviewed for background diseases, location of the dislocated IOL (intracapsular/extracapsular), insertion of a capsular tension ring (CTR), and the period from IOL insertion to dislocation.
RESULTS
We included 21 eyes of 21 patients who required IOL suture or intrascleral fixation for IOL dislocation at our clinic from January to December 2019 were included. The most common background disease was pseudoexfoliation syndrome (four cases), followed by atopic dermatitis, dysplasia/dehiscence of the zonule, post-retinal detachment surgery, high myopia, and uveitis (three cases each). At the time of dislocation, the IOLs were either intracapsular (16 cases, including 3 cases with CTR insertion) or extracapsular (5 cases). The time from IOL insertion to IOL dislocation was 13.7 ± 8.1 years (maximum: 31.3 years, minimum: 1.7 years).
CONCLUSIONS
In this study, all 21 cases represented late IOL dislocations occurring after 3 months postoperatively. Among these late IOL dislocation cases, IOL dislocation occurred in a short-medium period of time, especially in those with CTR insertion and weakness/dehiscence of the zonule, with an average of 3 to 5 years postoperatively. We propose referring to these cases as intermediate-term IOL dislocation.

Background Intestinal perforation is a life-threatening condition requiring immediate surgical intervention. Surgical-site infections (SSIs) and wound dehiscence are common complications associated with emergency laparotomy for intestinal perforation. Finding optimal wound management and postoperative strategies can significantly impact patient outcomes and reduce the risk of complications. Negative-pressure wound therapy (NPWT) is a relatively recent tool employed in the care of wounds to control SSIs and foster healing. Methodology A prospective, observational, cohort study was conducted among 150 patients who underwent emergency exploratory laparotomy due to intestinal perforation at the general surgery department of a tertiary care hospital in New Delhi between July 2022 and December 2023. Preoperatively, all patients underwent initial resuscitation. Intraoperatively, the extent of peritonitis was determined and was categorized according to the Centers for Disease Control and Prevention (CDC) classification. Postoperatively, NPWT dressing was applied to the patient's midline laparotomy wound on postoperative day (POD) two. Negative pressure was set at 75-125 mmHg with suction. The number of NPWT dressing changes required was documented. The wound was closed with vertical mattress sutures under local anesthesia, delayed primary closure (DPC). The incidence of SSIs, the duration for DPC, the incidence of fascial dehiscence, the number of NPWT dressing changes, and the length of hospital stay were documented according to CDC groups. Results The mean age in CDC categories 2, 3, and 4 were 31.789, 28.733, and 42.676 years, respectively. The most common cause of perforation was enteric fever (n = 42, 28%), followed by tuberculosis (n = 36, 24%). Most patients had no known comorbidities (n = 80, 53.3%). Overall, 16% of patients (n = 24) were both alcoholics and smokers. The most frequent bacteria in all CDC categories was . Fourteen patients developed burst abdomen in the postoperative period and were excluded from the study. The mean duration of DPC increased with higher CDC categories, with CDC category 4 displaying the most extended mean duration at 10.70 days. The number of NPWT dressing changes increases with higher CDC categories, with CDC category 4 exhibiting the highest mean at 2.00 changes. The mean hospital stay increased with higher CDC categories, with CDC category 4 showing the most extended mean stay at 17.324 days. Statistical analysis revealed no significant association between SSI occurrence and CDC categories. Conclusions NPWT followed by DPC is a promising approach to managing gastrointestinal perforations, reducing SSIs, and potentially improving patient outcomes. However, further research is needed to explore the specific benefits of NPWT in conjunction with DPC and its efficacy in various clinical scenarios.
