Tarsal tunnel syndrome caused by space occupying lesion is unusual but it rarely occur by ganglion which is presented below the flexor retinaculum due to compression neuropathy of posterior tibial nerve and its branches. The object of the current study is to report our experience of surgical treatment about tarsal tunnel syndrome caused by the ganglion of flexor digitorum longus tendon sheath and multifocal myxoid degeneration of medial plantar nerve with a review of the literatures.

Multifocal acquired demyelinating sensory and motor (MADSAM) neuropathy is a variant of chronic acquired demyelinating polyneuropathy. A 65-year-old women presented with upper arm weakness. A nerve conduction study showed conduction blocks over intermediate segments with sparing of distal compound action potentials. Magnetic resonance imaging revealed asymmetric hypertrophy of the brachial plexus on the affected side. These findings represent important electrophysiological and radiological evidence of MADSAM neuropathy. The condition of the patient began to improve after starting intravenous immunoglobulin administration.

We report a 29-year old female who developed bilateral femoral neuropathy combined with multiple abscesses in both thigh muscles. She was present with weakness in both lower extremities for 15 days and intermittent chilling sense for 3 months. Nerve conduction study showed complete absence of compound muscle action potentials in bilateral femoral nerves when stimulated at inguinal area. Electromyographic examination revealed no motor unit action potentials in both rectus femoris and vastus medialis muscles. CT revealed multifocal abscesses in bilateral thigh muscles. After antibiotic treatment, the patient's neurologic symptoms were improved.

A 44-year-old man with a past medical history of splenectomy came to hospital because of epigastric pain. Abdominopelvic computed tomography(CT) showed a soft tissue mass and multifocal variable-sized nodules as well as findings suggestive of cholecystitis. Subsequently, he underwent Tc-99m-labeled heat-denatured red blood cell(RBC) scintigraphy to evaluate the mass and nodules. The scintigraphy confirmed multifocal peritoneal splenosis in the abdominopelvic cavity.

In this study, we objectively determined whether the ReSTOR as a multifocal IOL (intraocular lens) has a multifocal function compared to the IQ as a monofocal IOL in vivo by OQAS (Optical Quality Analysis System). Eighteen patients who had cataract surgery with implantation of ReSTOR (27 eyes) and 15 patients with IQ (21 eyes), were included inthis study. Uncorrected distance visual acuity (UCDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UCNVA)and distance corrected near visual acuity (DCNVA) were measured. After setting the artificial pupil size to 3 mm, we performed 'Optical quality'. We inputted defocus diopters of (objective spherical refraction)(far), (objective spherical refraction-1.25 D)(intermediate),(objective spherical refraction-2.5 D)(near), and (objective spherical refraction-3.5 D)(very near) into 'selected spherical refraction' simulating the optical quality at far, intermediate, and near distance. We changed the pupil size to 5 mm and repeated the same measurements. The UCDVA and CDVA did not show significant differences between the 2 groups. But, the UCNVA and DCNVA of the ReSTOR group were better than those of the IQ group (p=0.000, p=0.000). For 3 mm pupil, at far distance, modulation transfer function (MTF) cut off and point spread function (PSF) width at 50% of ReSTOR were worse than those of IQ (p=0.039, p=0.020). At intermediate distance, MTF cut off, Strehl ratio and PSF width at 50% of ReSTOR were worse than those of IQ (p=0.001, p=0.001, p=0.000). At near distance, MTF cut off of ReSTOR was worse than that of IQ (p=0.033). At very near distance, MTF cut off and Strehl ratio of ReSTOR were worse than those of IQ (p=0.002, p=0.002), but PSF width at 50% of ReSTOR was better than that of IQ. For 5 mm pupil, most parameters at each distance, there was no significant difference between the 2 groups. Only PSF width at 50% of ReSTOR were worse than those of IQ at intermediate distance (p=0.013). It was impossible to show the multifocal function of ReSTOR compared to the IQ byOQAS.

An adult female ringed seal died suddenly and was subsequently examined for diagnostic purposes. The animal's lungs demonstrated mild non-collapsibility and multifocal white to yellow patches. Histopathological examination revealed multifocal pulmonary histiocytosis. Alveoli were filled with numerous foamy macrophages cytoplasm and scattered multinucleated giant cells containing cholesterol clefts. The foamy cytoplasm of the macrophages stained with oil red O stain. Further, lipid droplets within the cytoplasm were detected by electron microscopy. To the author's knowledge, this is the first case report describing the histochemical staining and electron microscopic findings associated with endogenous lipid pneumonia in ringed seal.

Total 160 head of porcine kidneys were examined for gross and histopathological lesions and polymerase chain reaction (PCR) for porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV), Leptospira species and porcine reproductive and respiratory syndrome virus (PRRSV). Grossly, 137 kidneys (85.6%) had lesions characterized by the presence of the scattered white foci. Microscopically, multifocal interstitial nephritis, which classified into 4 grades such as, no lesion (Score 0), mild lesion (Score 1), moderate lesion (Score 2) and severe chronic lesion (Score 3) with fibrosis, was observed in 159 cases (99.4%). The histopathologic mean score for multifocal interstitial nephritis was significantly different (P<0.05) between the cases of PCV-2 single infection and the cases of co-infection with PCV-2 and PPV. According to PCR evaluation, PCV-2 were detected in 73.8% (118 cases), PPV were in 66.9% (107 cases), however Leptospira spp. and PRRSV were negative in all kidneys. Both PCV-2 and PPV were detected in 52.5% (84 cases). In 84 cases co-infected with PCV-2 and PPV, the occurrence of lymphoid follicle and vasculitis were observed as 65.5% (55 cases) and 26.2% (22 cases), respectively. These results revealed that PCV-2 and PPV were major infectious agents for interstitial nephritis in slaughtered pigs, Jeju. And the histopathologic lesions of multifocal interstitial nephritis were more severe in the case co-infected with PCV-2 and PPV.

본 연구는 누진다초점렌즈 착용경향에 관하여 조사하는 것을 목적으로 하고 있다. 40세부터 65세까지의 중 장년층 성인남녀를 대상으로 타각적, 자각적 굴절검사를 시행하여 굴절이상을 측정하여, 노안안경 착용자의 노안 안경 가입도 분포 및 누진 다초점 착용경향에 관해 조사, 분석하였다. 가입도는 +0.75D에서 +3.00까지 검출되었고 40대 평균 가입도는 +1.18D, 50대 초반 평균가입도는 +l.55D, 50대 후반 평균 가입도는 +1.97D 그리고 61세 이상의 평균 가입도는 +2.38D로 검출되었다. 원용시력은 원시안 및 원시성 난시가 43%, 근시안 및 근시성 난시가 36%로 7% 높게 나타났고, 누진다초점렌즈 장용자중 무리한 근거리 작업으로 실내전용 다초점 렌즈를 부가적으로 사용하는 남성은 20%, 여성은 19%로 나타났다.

목적: 단기간의 중심외주시 훈련 후 발생하는 신경의 재조직화의 특성과 호발 위치를 알아보고자 했다. 방법: 정상시력을 가진 성인 14명을 대상으로 21일 간 중심외주시 훈련을 하고 훈련 전후 광지각도와 다국소망막전위도를 측정하여 사후 분석했다. 결과: 중심외주시 훈련 전후 값을 비교한 광지각도 검사(p<0.047)에서 뿐만 아니라 다국소망막전위도 검사에서도 유의한 개선을 보였다(p<0.028). 결론: 시각 말초신경계는 재생이 불가능하지만 단기간의 중심외주시 훈련은 말초신경계에서 신경 재조직화를 발생시킨다.

Nodular lymphoid hyperplasia (NLH) is a benign lymphoproliferative disease that can affect the lung. Because of its rarity, little is known about the etiology and natural history of NLH. Most cases are usually asymptomatic and found incidentally on imaging studies. Imaging finding of NLH has shown most commonly as a solitary lesion, although multifocal pulmonary nodules may be seen. Surgical resection has proved curative in the cases previously described. We report a rare case of NLH in a 55 year-old man who presented with bilateral multiple pulmonary nodules on chest radiography. Open biopsy was performed from the upper and lower lobe of the left lung. The lesions were pathologically diagnosed as pulmonary NLH. Multifocal residual nodules in both lungs remain stable without spontaneous regression during the 3 years of follow-up.
