Background: To date there had been no investigations using the International Classification of Primary Care, Second Edition (ICPC-2) at a clinic on an isolated island. In order to analyze health problems on the island, we investigated the reasons for visits, chronic illnesses, and the number of cases referred to other medical facilities using the ICPC-2.
Methods: The study was conducted over a 12-month period, from April 1, 2006 to March 31, 2007. Patient complaints/symptoms were classified according to ICPC-2, and diseases of patients who regularly visited the clinic as of November 2006 were investigated.
Results: Half of the patients that regularly visited the clinic had lifestyle-related or musculoskeletal diseases. On the first visit, several patients presented with cold, musculoskeletal, or skin symptoms. The specialist care to which the patients were most frequently referred was orthopedic surgery.
Conclusion: Physicians working at a clinic on an isolated island need to be able to control lifestyle-related diseases and provide initial treatment for musculoskeletal or skin diseases.

An 87-year-old woman with unknown fever origin was admitted to our internal department. We could not determine the fever origin from clinical findings, serious blood data, urine data, bacteriological data, and images obtained by ultrasonography, computed tomography and magnetic resonance. Body inflammatory findings did not respond to several antibiotics we used. Gallium scintiphotography revealed abnormal radioisotope uptake in the bilateral inguinal region. And ultrasonography and enhanced computed tomography showed tumors in front of the bilateral femur neck. Moreover, bone scintiphotography (^99mTc) revealed abnormal radioisotope uptake in the bilateral hip joints. We performed resection of the right inguinal tumor. The tumor was solid mass 30×20×20mm in size. It was covered with an articular capsule in front of the right femur neck. We identified the mass as bilateral tuberculous granulation with Langhans-type giant cells pathologically. It was only with difficulty that we firmly diagnosed the case as tuberculous arthritis of bilateral hip joints because the fever origin was unknown. It is important to diagnose tuberculous arthritis by use of various imaging techniques. We should take tuberculous infection into consideration when we encounter a case of arthritis of unknown fever origin or a case of antibiotics resistant arthritis.

Upper gastrointestinal endoscopy is an invasive examination. Cardiovascular and respiratory adverse effects are commonly observed in patients undergoing endoscopy. We investigated prospectively the cardiovascular and respiratory changes every oneminute before, during and after routine endoscopy. Sixteen healthy adult patients were enrolled in this study. Systolic blood pressure, diastolic blood pressure, pulse rate and percutaneous arterial oxygen saturation (SpO₂) were recorded every one-minute throughout the procedure. Systolic and diastolic blood pressure increased significantly one minute after the insertion of the endoscope. Increases in pulse rate were noted after the insertion of the endoscope. Rate pressure product increased significantly one minute after the insertion of the endoscope. No significant change in SpO₂ was observed during endoscopy. Our results indicated that upper gastrointestinal endoscopy might induce cardiovascular stress and abnormality. Therefore, we should carefully insert and manipulate upper gastrointestinal endoscope.

STUDY DESIGN: Cross-sectional study. PURPOSE: To determine the association between fatty degeneration of the multifidus muscle (Mm) and intervertebral disc degeneration (IVDD) using quantitative magnetic resonance imaging (MRI). OVERVIEW OF LITERATURE: Few studies have reported on quantitative MRI analysis of the relation between the Mm and IVDD. METHODS: The subjects with chronic low back pain comprised 45 patients (19 males, 26 females; mean age, 63.8±2.0 years; range, 41–79 years). We analyzed the intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL) of the Mm using magnetic resonance spectroscopy. The T2 values of the anterior annulus fibrosus (AF), nucleus pulposus (NP), and posterior AF were evaluated using MRI T2 mapping. We compared the possible correlations of IMCL and EMCL of the Mm with the T2 values of anterior AF, NP, and posterior AF. RESULTS: There was a significant negative correlation between IMCL and T2 values of the anterior AF (r=−0.65, p<0.01). There were no significant correlations between the IMCL and T2 values of NP (r=−0.16, p=0.30) and posterior AF (r=0.07, p=0.62). There were no significant correlations between the EMCL and T2 values of the anterior AF (r=−0.11, p=0.46), NP (r=0.15, p=0.32), and posterior AF (r=0.07, p=0.66). After adjustment for age and sex using multiple linear regression analysis, there was a significant negative correlation between the IMCL and T2 values of anterior AF (standardized partial regression coefficient=−0.65, p<0.01). CONCLUSIONS: The results indicated that IMCL of the Mm might be accompanied with anterior AF degeneration. Therapeutic exercises using IMCL of the Mm as evaluation index might have the potential to identify novel targets for the treatment and prevention of IVDD.

BACKGROUND: There have been several reports on neonates with milk allergy in a neonatal ward. This type of allergy is mostly categorized as a non-IgE-mediated food allergy. Although most cases of milk allergy occur in the first few months of life, the differences in clinical characteristics between premature and full-term neonates are still unclear. OBJECTIVE: This study aimed to clarify the differences in clinical characteristics of milk allergy between premature and full-term neonates. METHODS: We retrospectively evaluated 2,116 neonates admitted to the Department of Neonatology, Chiba Kaihin Municipal Hospital, between 2001 and 2007. RESULTS: We identified 24 neonates strongly suspected of having milk allergy because of symptoms, such as bloody stools, repeated vomiting, diminished sucking and abdominal distension, as well as objective laboratory findings of eosinophilia in stool cytology and/or positive results for a rectal milk challenge test. Twelve of these 24 neonates were premature (median gestational age, 31 ± 3 weeks; median birth weight, 1,656 ± 592 g) and the other 12 were full-term (median gestational age, 38 ± 1 weeks; median birth weight, 2,760 ± 560 g). There were no differences in symptoms and time to start of feeding between premature and full-term neonates, but there was a significant difference in the median postnatal age at onset (premature neonates: 23 days; vs. full-term neonates: 3.5 days; p < 0.01). CONCLUSION: All premature neonates developed a milk allergy after 32 weeks of corrected gestational age, suggesting that the development of milk allergy requires a certain degree of immunological maturation.

Background/Aims: Endoscopic submucosal dissection (ESD) is currently considered the first-line treatment for the eradication of superficial neoplasms of the esophagus in Eastern countries. However, in the West, particularly in Latin America, the experience with esophageal ESD is still limited because of the high technical complexity required for its execution. This study aimed to present the results of the clinical application of ESD to manage superficial esophageal neoplasms in a Latin American center in over 100 consecutive cases. Methods: This retrospective study included consecutive patients who underwent endoscopic ESD for superficial esophageal neoplasms between 2009 and 2022. The following clinical outcomes were assessed: en bloc, complete, and curative resection rates, local recurrence, adverse events, and procedure-related mortality. Results: Esophageal ESD was performed mainly for squamous cell carcinoma (66.6%), high-grade intraepithelial neoplasia (17.1%), and adenocarcinoma (11.4%). En bloc and complete resection rates were 96.2% and 81.0%, respectively. The curative resection rate was 64.8%. Adverse events occurred in six cases (5.7%). Endoscopic follow-up was performed for an average period of 29.7 months. Conclusions ESD performed by trained operators is feasible, safe, and clinically effective for managing superficial neoplastic lesions of the esophagus in Latin America.

Background/Aims: Mucosal cutting biopsy (MCB) is useful for the histopathological diagnosis of gastric subepithelial tumors (SETs). However, there is little information on cases in which MCB did not establish a diagnosis. In the current study, we aimed to investigate the characteristics of cases in which MCB was unsuccessful. Methods: Cases in which MCB was used to histopathologically diagnose gastric SETs at Kobe University Hospital between August 2012 and October 2018 were retrospectively reviewed. Results: Forty-five cases in which MCB was used to diagnose 43 gastric SETs in 43 patients were analyzed. The median tumor size was 20 mm (range, 8–50 mm). Pathological examinations resulted in definitive and suspected diagnoses and no diagnosis in 29 (gastrointestinal stromal tumor: n=17, leiomyoma: n=7, aberrant pancreas: n=3, others: n=2), 6, and 10 cases, respectively. Failure to expose the tumor according to retrospective examinations of endoscopic images was significantly associated with no diagnosis. Other possible explanations included a less elevated tumor, biopsy of the surrounding field instead of the tumor due to the mobility, and poor endoscope maneuverability due to the tumor being close to the cardia. Conclusions Clear exposure of gastric SETs during MCB may improve the diagnostic rate of such examinations.

STUDY DESIGN: Cross sectional study. PURPOSE: The study aimed to analyze mechanisms underlying chronic low back pain (CLBP) using magnetic resonance imaging (MRI) T2 mapping of the intervertebral disc (IVD). OVERVIEW OF LITERATURE: MRI T2 mapping utilizes the T2 values for quantifying moisture content and collagen sequence breakdown. We previously used MRI T2 mapping for quantifying the extent of IVD degeneration (IVDD) and showed a correlation between the degeneration of the posterior annulus fibrosus (AF) and CLBP. METHODS: We enrolled 40 patients with CLBP (17 males, 23 females; mean age, 50.8±1.6 years; range, 22–60 years). IVDs were categorized as the anterior AF, nucleus pulposus (NP), and posterior AF, and T2 value for each disc was measured. T2 values, assessed using the Japanese neuropathic pain (NeP) screening questionnaire, of the NeP and nociceptive pain (NocP) groups were compared. RESULTS: T2 values of the NocP and NeP groups were 64.7±5.6 ms and 58.1±2.3 ms for the anterior AF; 67.0±4.6 ms and 59.6±2.1 ms for NP; and 70.7±4.6 ms and 51.0±1.2 ms for the posterior AF, respectively. T2 values for IVDD were significantly lower in the NeP group than those in the NocP group (p<0.01). CONCLUSIONS: The results indicate a correlation between the degeneration of posterior AF and NeP. MRI T2 mapping may be beneficial for detecting NeP caused by IVDD and can help formulate targeted analgesic therapies.
