Abdominal pain is one of the common presentations in severe dengue infection. We report a rare case of perforated gastric ulcer in a young man diagnosed with severe dengue infection and the challenges we faced in managing this patient. Perforated gastric ulcer need to be considered if there are signs of peritonitis and persistent abdominal pain that does not conform to the natural history of de...

Perforated ulcers are a rare cause of abdominal pain, and may not be considered when pain is localized to the right lower quadrant (RLQ). This case highlights an unusual presentation of a perforated duodenal ulcer that presented with RLQ pain, which has been described as Valentino’s Syndrome. Valentino’s Syndrome occurs when gastric or duodenal fluids collect in the right paracolic gutter causi...

A perforated sigmoid colon cancer within an inguinal hernia is extremely rare. This unexpected finding is usually discovered during surgery and causes an unavoidable septic evolution. Here, we describe the case of an 84-year-old man who presented with fever, abdominal distension, and a painful, enlarged, left scrotum. A CT showed a left, incarcerated, inguinal hernia containing a perforated sig...

BACKGROUND To develop an evidence-based protocol for the management of perforated sigmoid diverticular disease. METHODS A search of the literature was undertaken. All publications pertaining to perforated sigmoid diverticular disease were analyzed and then categorized according to their level of evidence. Recommendations were then made on the basis of this. RESULTS Multiple case reports sug...

Acute perforated appendicitis is a very rare initial presentation of appendiceal lymphoma. A case of primary lymphoma of the appendix in a 42-year-old female is reported here. The symptom was pain in the right lower quadrant of the abdomen. Surgical intervention was performed under clinical diagnosis of acute appendicitis. Grossly, the resected appendix was gangrenous and perforated. Light micr...

BACKGROUND Environmental determinants of appendicitis are poorly understood. Past work suggests that air pollution may increase the risk of appendicitis. OBJECTIVES We investigated whether ambient ground-level ozone (O3) concentrations were associated with appendicitis and whether these associations varied between perforated and nonperforated appendicitis. METHODS We based this time-stratif...

BACKGROUND The literature established that, in patients without Boey's risk factors, laparoscopic repair of perforated peptic ulcers, compared to open repair, is associated to lower wound infection rate, less analgesic use, reduction in post operative pain, shorter hospital stay. Some of the main drawbacks are length of operative time and laparoscopic surgeon's experience in intracorporeal knot...

BACKGROUND Perforated peptic ulcers (PPU) present as serious surgical emergencies that carry high mortality and morbidity. Foreigners with PPU are also managed in our hospital setting. Their inclusion significantly alters the trend and pattern of PPU seen in Malaysia. AIM To compare per-operative and post-operative features and outcomes of perforated peptic ulcers between Malaysians and forei...

BACKGROUND Performing a delayed primary wound closure is often recommended in patients with gangrenous or perforated appendicitis who have undergone an appendectomy. It can result in increased pain as well as an extended hospital stay which, in turn, increases hospital costs. Delayed primary wound closure remains controversial. The general policy in our institution is to perform a primary wound...

The paper is a continuation of the works "Modelling of viscous damping of perforated planar micromechanical structures. Applications in acoustics" [Homentcovschi and Miles, J. Acoust. Soc. Am. 116, 2939-2947 (2004)] and "Viscous Damping of Perforated Planar Micromechanical Structures" [Homentcovschi and Miles, Sensors Actuators, A119, 544-552 (2005)] where design formulas for the case of an off...
