This paper evaluates the contribution of waves to the total predicted storm surges in a Hurricane Irma hindcast, using ADCIRC+SWAN and ADCIRC models. The contribution of waves is quantified by subtracting the water levels hindcasted by ADCIRC from those hindcasted by ADCIRC+SWAN, using OWI meteorological forcing in both models. Databases of water level time series, wave characteristic time series, and high-water marks are used to validate the model performance. Based on the application of our methodology to the coastline around Florida, a peninsula with unique geomorphic characteristics, we find that wave runup has the largest contribution to the total water levels on the south and northeast coasts. Waves increase the surge on the south and northeast coasts, due to large fetch and wave runups. On the west coast, the wave effect is not significant, due to limited fetch. However, significant wave heights become greater as the waves propagate into the deep inner gulf. The continental shelf on Florida’s west coast plays a critical role in decreasing the significant wave height and sheltering the coastal areas from large wave effects. Both models underpredict the high-water marks, but ADCIRC+SWAN reduces the underprediction and improves the parity with the observed data, although the scatter is slightly higher than that of ADCIRC.
Hydrocele of the canal of Nuck is a rare abnormality, developing in the protruded part of the parietal peritoneum within the inguinal canal in a female. It is homologous to the processus vaginalis in males and obliterates from the seventh month of gestation to one year of age. Failure of obliteration, results in Nuck hydrocele or herniation of intra-abdominal contents through the patent Canal of Nuck. These are usually detected and repaired in young girls within the first five years of life. Reports of Canal of Nuck hydrocele in adults are sparse. Most of these patients are misdiagnosed on clinical examination and correctly diagnosed intraoperatively during surgery for suspected ‘inguinal hernia’. Here, this case is about a 25-year-old female, who presented with swelling in the right groin for one month. Computed Tomography of the abdomen showed features suggestive of a hydrocele within the Canal of Nuck. She underwent laparoscopic hydrocelectomy and laparoscopic hernia repair via the transabdominal preperitoneal approach. This case report highlights the novel approach of laparoscopic management of this rare case.
The kidney is an organ prone to congenital anomalies owing to its complex and sequential development. Ectopia of the kidney is a rare entity with intrathoracic ectopia being an exceptionally uncommon occurrence. Intrathoracic kidneys represent less than 5% of all renal ectopias with a prevalence rate of less than 0.01%. The concurrent association of an intrathoracic kidney with a Bochdalek hernia is extremely infrequent with an incidence of 0.25%. Most of the patients are asymptomatic and have an uneventful clinical course. It is often incidentally detected simulating a posterior mediastinal mass. Thoracic kidney is a condition that shows male predominance. Here, present case is of a 43-year-old female patient who presented to the institution with breathlessness and associated chest pain. Computed Tomography (CT) scan revealed left-sided Bochdalek hernia with the left kidney, adrenal gland, transverse colon, splenic flexure and proximal descending colon within the thorax. The patient underwent elective diagnostic laparoscopy followed by reduction of the contents and mesh repair of the diaphragmatic defect. The patient was discharged and remained asymptomatic on a periodic follow-up of over a year. Awareness regarding this rare entity can obviate the need for a battery of unnecessary investigations and operative procedures.
Incisional hernia which if not repaired at the earliest might increase in size and eventually end up in complications like incarceration or strangulation. Perforation of the bowel loop in case of incarcerated or strangulated incisional hernia without any precipitating events like trauma is very rare. Intestinal perforation, if identified is a life-threatening condition that requires emergency surgical management. Perforation of the small bowel along its mesenteric border is a rare entity with only very few cases being reported. Authors hereby, present a case of a 55-year-old female with long standing incisional hernia who was diagnosed as an incarcerated incisional hernia after computed tomography and was proceeded with an exploratory laparotomy, which on further exploration revealed perforation of the incarcerated ileum along its mesenteric border for which resection and anastomosis was done.
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.
