Rigler’s sign was first described in 1941 by L G Rigler as a new radiological sign for recognising free air in the peritoneal cavity on supine radiograph. The presence of pneumoperitoneum allows free intraperitoneal air to be contrasted with intraluminal gas, accentuating the wall of gas-containing viscera. It is observed in infants and very ill patients where only limited radiographs of the abdomen are possible. The football sign was first described by R E Miller in the 1960s. Seen on supine abdominal radiographs, this describes an oval radiolucency resembling an American football. It is important for the radiologist to recognise the supporting signs of pneumoperitoneum, such as Rigler’s sign and the football sign, on supine abdominal radiographs, especially in neonates and infants, where erect chest/abdominal radiographs are not always possible.

Two cases are presented which emphasize the difficulty of differentiating between a sigmoid volvulus, where the 'liver overlap sign' is the only sign present, and perforation of a hollow viscus where the only sign on a supine abdominal radiograph may be the 'football sign' simulating a 'liver overlap sign'. In the case of sigmoid volvulus described in this report, the correct diagnosis established only with much difficulty and after further conventional radiographs and contrast studies.

The authors describe a new technique for revision of an occluded distal ventriculoperitoneal shunt catheter that obviates the need for laparotomy or trocar insertion into the peritoneal cavity. The authors review their early experience with 34 patients suffering from a distal ventriculoperitoneal shunt failure and treated with this technique. There were no incidents of intraabdominal injury or wound complications. In 2 patients conversion to a minilaparotomy was required for safe placement of the shunt. Proper peritoneal placement was confirmed with abdominal radiographs in all cases. This technique has been safe and effective and may be considered an alternative to traditional laparotomy or laparoscopic methods.

Background: Pneumoperitoneum without any gastrointestinal (GI) perforation or peritonitis is entitled spontaneous pneumoperitoneum. We aimed to describe a radiological perspective in spontaneous pneumoperitoneum. Methods: This case series presented data of 4 cases of spontaneous pneumoperitoneum managed at our institution. Results: There were 85 patients with a provisional diagnosis of necrotizing enterocolitis (NEC) and/or pneumoperitoneum. Out of these, there were 4 patients with the final diagnosis of spontaneous pneumoperitoneum; three males and 1 female. At presentation, respiratory distress was seen in 3. It was preceded by mechanical ventilation in 3 patients. All 4 had soft abdominal distension, absence of features suggestive of peritonitis, and the presence of free air with an absence of air-fluid level in peritoneal cavity on erect abdominal radiographs. The Rigler sign was present in 3 patients. Abdominocentesis followed by abdominal drain placement was performed in 2 patients. Laparotomy was performed in 1 patient which could not point to any pathology (negative). An unfavorable outcome was seen in one patient with associated esophageal atresia. No patient had any evidence (either ultrasound/radiological or on laparotomy) of leakage of contents from the GI tract. Conclusions: In infants, especially preterm neonates, presenting with soft abdominal distension with abrupt onset of pneumoperitoneum, without clinical features of peritonitis and preceded by mechanical ventilation, diagnosis of spontaneous pneumoperitoneum should be considered.

This chapter charts the National Football League's (NFL) meteoric rise, thanks to NFL Films' unwavering designation of pro football as a unique and unifying reflection of America. Fueled by a combination of sport and media's increasingly profitable symbiosis and Commissioner Pete Rozelle's image-consciousness, the NFL enhanced its marketing efforts during the 1960s and began to diversify aggressively, creating branded products that reached out to audiences beyond the white, middle-class men who composed its typical fan base. The Rozelle-era NFL solidified its prominence in American culture through its merger with the American Football League and subsequent development of the Super Bowl. This chapter examines how the NFL made connections to as many potential fans as possible by establishing national television exposure, branding various items, organizing athletic events for kids, donating to charitable causes, and creating a tourist attraction. It looks at one production that codified NFL Films' signature aesthetic practices, They Call It Pro Football, and how it situates professional football as “the sport of our time.”

ABSTRACT The objective of this report is to document a case of pneumatosis coli in an immunosuppressed dog successfully treated with supportive care that included hyperbaric oxygen. A 9 yr old, neutered male Maltese was presented for hematochezia of ∼36 h duration. The dog had a history of immune-mediated thrombocytopenia that was well managed with prednisone and azathioprine. Initial evaluation was unremarkable except for increased rectal temperature and hematochezia on digital rectal examination. Abdominal radiographs revealed diffuse gas within the colonic wall consistent with pneumatosis coli. Scant-free air was also appreciated in the peritoneal and retroperitoneal cavities. The dog was managed for 4 days in hospital with broad spectrum antibiotic, anthelminthic, and gastroprotectant therapy. He received one session of hyperbaric oxygen therapy while in hospital. Repeat abdominal radiographs after 72 hr of medical management showed improvement of the pneumatosis coli. After 4 days of hospitalization, he was discharged with resolution of clinical signs. Pneumatosis coli is rarely diagnosed in dogs but should be considered in cases with clinical signs of colorectal disease.

We report an extremely rare event where the use of diathermy to enter the peritoneal cavity caused the free gas within it to ignite and consequently burn the surgeon during a standard right hemicolectomy procedure for a caecal perforation. This should be noted as a possible safety concern intraoperatively. We conclude that sharp dissection should always be used initially when entering the peritoneal cavity where free gas is present, cautery can subsequently be used once the free air has escaped.

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Ultrastructural Studies

In the circulating blood of man and guinea pigs, glycogen occurs primarily in polymorphonuclear neutrophils and platelets. The amount of glycogen in neutrophils increases with time after the cells leave the bone marrow, and the distribution of glycogen in neutrophils changes from an apparently random distribution to large clumps when these cells move out of the circulation to the site of inflammation in the peritoneal cavity. The objective of this study was to further investigate changes in glycogen content and distribution in neutrophils. I chose an intradermal site because it allows study of neutrophils at various stages of extravasation.Initially, osmium ferrocyanide and osmium ferricyanide were used to fix glycogen in the neutrophils for ultrastructural studies. My findings confirmed previous reports that showed that glycogen is well preserved by both these fixatives and that osmium ferricyanide protects glycogen from solubilization by uranyl acetate.I found that osmium ferrocyanide similarly protected glycogen. My studies showed, however, that the electron density of mitochondria and other cytoplasmic organelles was lower in samples fixed with osmium ferrocyanide than in samples fixed with osmium ferricyanide.
