A case of strangulation of the transverse colon in a traumatic left diaphragmatic hernia manifesting as pericarditis is reported. This is unusual because pericardial signs in traumatic diaphragmatic hernia have been previously described in association with direct pericardial injury. This is the only such case where electrocardiographic changes of pericarditis were seen without direct pericardial trauma. The possibility of internal herniation through a traumatic diaphragmatic hernia must be considered in patients with chest symptoms and a compatible history.

Laparoscopic colon surgery for select cancers is slowly evolving as the standard of care but minimally invasive approaches for rectal cancer have been viewed with significant skepticism. This procedure has been performed by select surgeons at specialized centers and concerns over local recurrence, sexual dysfunction and appropriate training measures have further hindered widespread acceptance. Data for laparoscopic rectal resection now supports its continued implementation and widespread usage by expeienced surgeons for select patients. The current controversies regarding technical approaches have created ambiguity amongst opinion leaders and are also addressed in this review.

This paper proposes a novel design paradigm for circuits designed in quantum dot cellular automata （QCA） technology. Previously reported QCA circuits in the literature have generally been designed in a single layer which is the main logical block in which the inverter and majority gate are on the base layer, except for the parts where multilayer wire crossing was used. In this paper the concept of multilayer wire crossing has been extended to design logic gates in multilayers. Using a 5-input majority gate in a multilayer, a 1-bit and 2-bit adder have been designed in the proposed multilayer gate design paradigm. A comparison has been made with some adders reported previously in the literature and it has been shown that circuits designed in the proposed design paradigm are much more efficient in terms of area, the requirement of QCA cells in the design and the input-output delay of the circuit. Over all, the availability of one additional spatial dimension makes the design process much more flexible and there is scope for the customizability of logic gate designs to make the circuit compact.
