Paraduodenal hernias are rare congenital malrotational anomalies of midgut that arise in the potential spaces and folds of the posterior parietal peritoneum adjacent to the ligament of Treitz and can lead to intestinal obstruction. Also, they have shown several presentation patterns, such as asymptomatic, chronic intermittent abdominal pain, and acute severe abdominal pain. If symptomatic hernias with strangulation are untreated, according to the previous reports, they lead to overall mortality exceeding 50%. We report a case of the left paraduodenal hernia combined with small bowel obstruction from the patient who had no history of surgery before and developed abdominal pain after drinking of alcohol heavily. Abdominal CT scan showed sac-like mass of clustered in the left upper quadrant. The patient underwent the surgery of the bowel reduction and adhesiolysis and got uneventful recovery.

The facial nerve is mainly composed of motor fibers and is distributed to the muscles of facial expressions. In ophthalmology clinics, orbicularis oculi muscle innervated by the facial nerve is involved in spontaneous and voluntary blinking, winking, and more forceful eyelid closure. To understand pathophysiogy of facial nerve palsy due to brain stem lesion involving nucleus, 50% Horseradish Peroxidase (HRP) was injected into nerve stump innervating orbicularis oculi muscle of cat and serial sections of midbrain were studied with light and dark field of light microscope to examine morphology and distribution of the facial nuclei. The HRP-labelled motor neurons were located exclusively within the intermediate division of the ipsilateral facial nuclei and no labelled neurons were found in the contralateral facial nuclei, in the nuclei of the trigeminal nerve, or any other brain stem nuclei. The mean diameter of HRP-labelled motor neurons was 45 micrometer. Most of them were multipolar in shape containing many dendrites. These result suggest that the intermediate division of ipsilateral facial nuclei play an important role in innervating orbicularis oculi muscle.
