Pancoast syndrome (PS) is characterized by a malignant neoplasm of the superior sulcus of the lung with destructive lesions of the thoracic inlet and involvement of the brachial plexus and cervical sympathetic nerves. The most common initial symptom of PS is shoulder pain; however, cough, dyspnea, and hemoptysis, signs often associated with lung cancer, are not as common. Investigation of PS can be difficult even with plain radiographs of the chest because it is surrounded by osseous structures such as the ribs, vertebral bodies, and manubrium. Due to these characteristics, orthopedic surgeons tend to make a misdiagnosis resulting in delay of appropriate treatment. Here we report on a patient who was supposed to undergo rotator cuff repair for his shoulder pain and weakness, and was eventually diagnosed with PS.

Between November 2005 and March 2006, a total of 253 poultry flocks in the Gyeonggi-do of Korea were examined for seroprevalence against avian influenza (AI) using a hemagglutination inhibition (HI) test and an agar gel precipitation test. No low pathogenic avian influenza (LPAI) virus was isolated from 47 seropositive flocks that lacked clinical signs during sampling. The unadjusted percentage of seroprevalence rates of layer and broiler flocks were not significantly different, i.e., 26% (25/96) and 23% (22/97), respectively. The HI titer of the layers (mean = 89) was higher than the broilers (mean = 36; p < 0.001). A cross-sectional study was conducted for the seroprevalence of LPAI in the layers. Of 7 risk factors, farms employing one or more workers had a higher seropositive prevalence as compared to farms without hired employees (adjusted prevalence OR = 11.5, p = 0.031). Layer flocks older than 400 d had higher seropositivity than flocks younger than 300 d (OR = 4.9, p = 0.017). The farmers recognized at least one of the clinical signs in seropositive flocks, such as decreased egg production, respiratory syndromes, and increased mortality (OR = 2.3, p = 0.082). In a matched case-control study, 20 pairs of case and control flocks matched for type of flock, hired employees, age, and flock size were compared. Frequent cleansing with disinfectants was associated with a decreased risk of seropositivity (OR = 0.2, p = 0.022). Although there was a low statistical association, using a foot disinfectant when entering the building led to a decreased rate of seropositivity (OR = 0.3, p = 0.105).

We have analyzed 100 urinary calculi by chemical analysis, which obtained from the patients admitted our department during the period from March, 1981 to February, 1983. The following results were obtained: 1. The results of chemical analysis of 100 urinary calculi revealed calcium oxalate phosphate in 43%, calcium oxalate in 19%, calcium phosphate in 15%, ammonium phosphate in 12%, carbonate calcium oxalate phosphate in 7%, uric acid in 2%, acid + calcium phosphate in 2%. 2. 40 of 100 patients with urinary stones showed bacteriuria and Staphylococcus epidermidis was the most frequent organism. 3. The causative diseases of the urinary stones were renal tuberculosis 4 cases, neurogenic bladder in 4 cases, urethral stricture in 3 cases, BPH in 1 case and hyperparathyroidism in 1 case. 4. The incidence of high urinary calcium amount was greater in lithiasis group(43%) than in control group(17%) The incidence of high urinary calcium amount in lithiasis group was as following order: calcium oxalate phosphate in 55.8%, calcium phosphate in 46.7%, calcium in 42.1% and ammonium phosphate in 28%.

Neurofibromatosis type 2 (NF2) is an autosomal dominant disease characterized by bilateral vestibular schwannomas and other central nervous tumors such as meningiomas and spinal ependymomas. Symptoms vary according to the age at diagnosis and the location of these tumors. The diagnostic criteria of NF2 have been regularly revised and recently updated in 2022 with a new nomenclature “NF2-related schwannomatosis” to differentiate NF2 from other schwannoma predisposing disorders, such as SMARCB1 (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily b, member 1)-, LZTR1 (leucine zipper-like transcription regulator 1)-, and 22q-related schwannomatosis. Addition to the clinical features, genetic testing for pathogenic variants in these genes became an important essence to support diagnosis of NF2 and other schwannomatosis, including mosaic conditions.
