Pancreatic contour variations can be detected incidentally on computed tomography (CT). Recognition and remembering of these variations are important in volumetric measurements and surgery as well as in preventing misdiagnosis. ⋯ Pancreatic variations detected in CT examinations for distinct reasons are not rare; these variations should be recognized and remembered.

Splenomegaly and Splenic Pseudocyst in a Female Teenage Patient with Sickle Cell Anemia-A Case Report.
Splenomegaly is one of the complications of sickle cell disease (SCD) occurring in early childhood. This risk is reduced by the age of five years as the spleen undergoes auto splenectomy as a consequence of recurrent vasooclusion and splenic infarction. However, in some variants of SCD, the persistence of the spleen occurs. ⋯ Many patients with splenic pseudocyst are usually asymptomatic and do not need intervention. However, the index patient developed serious symptoms indicating a need for a total splenectomy. A splenic pseudocyst is rare and found in <1% of splenectomies.

Midline catheters have been proposed as alternatives to central venous catheters and peripherally inserted central catheters. Midline catheters reduce the incidence of overall needle stick injuries during hospitalization, have lower complication rates than central venous catheters or peripherally inserted central catheters, and provide potential cost benefits for hospitals. ⋯ For the safe use of midline catheters, accurate and delicate insertion techniques should be practiced. More case studies are warranted to verify the usefulness and convenience of various types of midline catheters for their universal use.

In this study, the aim was to research the effects of smoking habits on controlled hypotension administered with nitroglycerin during ear-nose-throat surgery. ⋯ Nitroglycerin, chosen for controlled hypotension to reduce hemorrhage in the surgical field during nasal surgery, was shown to cause more pronounced hypotension and reflex tachycardia due to endothelial dysfunction linked to nicotine in patients who smoke. Despite lower pressure values in the smoking group, the negative effects of nicotine on platelet functions combined with similar effects of nitroglycerin to increase bleeding amounts.

In endodontic treatment, the aim is to completely determine, shape, and fill all root canals in a three-dimensional way. Missed canals lead to treatment failure. In mandibular molars, there may be an extra canal called the middle mesial canal between the mesiobuccal and mesiolingual canals. ⋯ Clinicians performing endodontic treatment of mandibular molar teeth should not ignore the presence of the middle mesial canal. Thus, it is very important for clinicians to have sufficient information about the localization, morphology, and variations of the middle mesial canal.
