Case report of an umbilical urachal cyst presenting as an infected umbilical hernia.
Congenital abnormalities such as these may present as a periumbilical soft tissue infection.
Complete excision of the urachal cyst for pathologic examination is recommended.
Patients can be successfully treated with short course of antibiotics and total excision.

Urinary bladder rupture is uncommon, occurring in 0.36% of blunt abdominal trauma.
Intraperitoneal ruptures are emergencies with >20% mortality when undiagnosed.
CT and plain film cystography are the most sensitive and specific diagnostic imaging.
Indwelling bladder catheters should remain in for at least 7 days postoperatively.
Studies on the first years of radioactive iodine (RAI) use in thyroid diseases have focused on hyperthyroidism. Saul Hertz’s success with RAI in thyrotoxicosis fueled a seamless transition to Samuel Seidlin’s investigations with RAI in thyroid cancer. These landmark events embody nuclear ontology, a philosophical foundation for the creation and existence of radio-therapeutic principles that continue to influence clinical practices today. Laying this ontological foundation, Dr. Saul Hertz who is the founding director of Massachusetts General Hospital Thyroid Clinic, affiliated with Harvard University created a framework for RAI theranostics with preclinical experiments and clinical cases from 1937 to 1942. The first thyroid cancer treatment with RAI was applied in 1942 by Samuel Seidlin. The sensational effect of the first application was interestingly powerful enough to overshadow scientific data. Seidlin and colleagues assembled a sixteen-patient series showcasing a unique entity: functional thyroid metastases that respond to RAI. Other investigations at the time demonstrated that RAI had little efficacy as a therapeutic agent, mainly because most thyroid tumors do not form colloid, and therefore cannot concentrate RAI. These findings were soon overshadowed by a mainstream article in the October 1949 issue of Life that portrayed RAI as a lifesaving therapy for thyroid cancer. The paradigm was set, and later writings by William H. Beierwaltes and other prominent nuclear medicine physicians established the primary goals and principles of RAI therapy. The developments in theoretical physics and nuclear instrumentation and the scientists who made these developments in the early years contributed greatly to the development of the concept. In the field of nuclear medicine, William H. Beierwaltes has gone down in our history as a clinical researcher with his most important contributions. The classical paradigm that started with him has carried us to today’s molecular theranoistic viewpoint. This paper examines controversial topics in the advent of thyroid theranostics, and applies historical significance to current discussions on the role of RAI in thyroid cancer management. Another paradigm shift is on the horizon as thyroidology enters the age of genomics. The molecular theranostic profiles will soon be incorporated into a dynamic clinical decision-making and management algorithm for thyroid surgery and RAI therapy. From now on, nuclear oncology will gain a new ontological identity with molecular pathology and new theranostic expansions.
Boating has exposed humans to elemental hazards for centuries. What was once a lifelong craft and time-honored skillset is now, with modern technology, a popular recreational activity. Boating safety has inherent limitations and has been historically challenging to enforce. These circumstances have given way to a rising number of watercraft-associated injuries and fatalities. This review aims to investigate the diagnosis, work-up, and management of watercraft-related injuries, including blunt mechanisms, propeller wounds, water-force trauma, associated marine infections, and submersion injuries, as well as outline gaps in current public health policy on watercraft injuries, potential interventions, and available solutions. Motorboats and personal watercraft differ in size, power modality, and differential risk for injury. Accidents aboard watercraft often share commonalities with motor vehicles and motorcycles, namely: rapid deceleration, ejection, and collision with humans. The complexity of care is added by the austere environment in which many watercraft accidents occur, as well as the added morbidity of drowning and hypothermia. Wounds can also become infected by marine organisms, which require wound care and antimicrobial therapy specific to the aquatic environment in which the injury occurred. The treatment of these patients can be further exacerbated by the prolonged transportation times due to complicated water rescue. There are many measures that can prevent or abate watercraft injuries, but inconsistent regulations and enforcement may impair the success of these interventions. Further research is needed to identify possible solutions to common causes of watercraft injuries, such as inconsistent lifejacket use and bow riding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
