Background/Aims: Chronic constipation is prevalent yet under-diagnosed across Asia, compromising quality of life and burdening healthcare systems. Cultural stigma, varied diets, and limited access to standardized diagnostic tools delay timely care. Methods: The Bali Chronic Constipation Roundtable in November 2024, brought together experts from 11 Asian countries. The group reviewed epidemiological data, analyzed multinational questionnaire on clinical practice pattern, and conducted structured discussions to identify key barriers and propose region-specific recommendations. Results: Chronic constipation prevalence varies across Asia, ranging from 1.8% in India to 16.6% in Japan, with women and the elderly disproportionately affected. Under-reporting persists owing to cultural taboos and widespread self treatment with laxatives and traditional medications. Although the Rome IV criteria remains the global standard, they may not fully reflect Asian symptom profiles, and diagnosis is limited by scarce motility laboratories. First line therapies such as dietary-fiber optimization and osmotic laxatives are widely available, but newer pharmacotherapies (prucalopride, linaclotide, lubiprostone, and elobixibat) remain costly and unevenly accessible. Biofeedback for dyssynergic defecation is underutilized due to limited availability. Experts recommend expanded regional research on to refine diagnostic criteria, coupled with enhanced physician education and public awareness. They advocate accessibility to second-line and novel therapies that incorporate culturally attuned regional guidelines, and improved access to gastrointestinal motility testing. Conclusions The Bali Chronic Constipation Roundtable highlighted Asia’s need for region specific diagnostics and management. Addressing diagnostic and treatment gaps will improve outcomes, while ongoing researcher clinician policy collaboration must standardize guidelines, advance research, and ensure equitable care across Asia.

In-depth study of the components of polymyxins is the key to controlling the quality of this class of antibiotics. Similarities and variations of components present significant analytical challenges. A two-dimensional (2D) liquid chromatography-mass spectrometr (LC-MS) method was established for screening and comprehensive profiling of compositions of the antibiotic colistimethate sodium (CMS). A high concentration of phosphate buffer mobile phase was used in the first-dimensional LC system to get the components well separated. For efficient and high-accuracy screening of CMS, a targeted method based on a self-constructed high resolution (HR) mass spectrum database of CMS components was established. The database was built based on the commercial MassHunter Personal Compound Database and Library (PCDL) software and its accuracy of the compound matching result was verified with six known components before being applied to genuine sample screening. On this basis, the unknown peaks in the CMS chromatograms were deduced and assigned. The molecular formula, group composition, and origins of a total of 99 compounds, of which the combined area percentage accounted for more than 95% of CMS components, were deduced by this 2D-LC-MS method combined with the MassHunter PCDL. This profiling method was highly efficient and could distinguish hundreds of components within 3 h, providing reliable results for quality control of this kind of complex drugs.

Medication-related osteonecrosis of the jaw (MRONJ) is a refractory disease that can lead to severe destruction of the jaw. As there is no standard protocol for treating MRONJ, various treatments have been studied. Teriparatide has been used as an adjunct therapy for MRONJ. However, its effectiveness has not been sufficiently demonstrated for use as a standard treatment for MRONJ. This study aimed to demonstrate the efficacy of teriparatide in treating MRONJ by presenting two successfully treated cases. Each patient received teriparatide therapy with surgical intervention. The appropriateness of teriparatide use was evaluated based on the patient’s systemic condition, and the administration of teriparatide was supervised by a physician.Complete resolution of the lesion was observed clinically and radiographically in both patients. The first patient underwent implant placement at the lesion site. Due to its anabolic properties and ability to stimulate bone remodeling, teriparatide is an effective adjunctive pharmacological treatment for bone healing before and after surgery with associated beneficial effects on bone and mucosal healing.

OBJECTIVE: The purpose of this study was to find an optimal delivery route for clinical trials of intrathecal cell therapy for spinal cord injury in preclinical stage.METHODS: We compared in vivo distribution of Cy5.5 fluorescent dye in the spinal cord region at various time points utilizing in vivo optical imaging techniques, which was injected into the lateral ventricle (LV) or cisterna magna (CM) of rats.RESULTS: Although CM locates nearer to the spinal cord than the LV, significantly higher signal of Cy5.5 was detected in the thoracic and lumbar spinal cord region at all time points tested when Cy5.5 was injected into the LV. In the LV injection Cy5.5 signal in the thoracic and lumbar spinal cord was observed within 12 hours after injection, which was maintained until 72 hours after injection. In contrast, Cy5.5 signal was concentrated at the injection site in the CM injection at all time points.CONCLUSION: These data suggested that the LV might be suitable for preclinical injection route of therapeutics targeting the spinal cord to test their treatment efficacy and biosafety for spinal cord diseases in small animal models.

PURPOSE: The purpose of this study was to analyze the diagnostic availability and to examine the co-relation between pedobaragraphy and radiography of pediatric flexible flatfoot. MATERIALS AND METHODS: Seventeen patients and ten normal children were studied. In radiographic evaluation, the talo-1st metatarsal angle was measured on anteroposterior radiographs; and the talo-1st metatarsal angle, the talo-horizontal angle, the calcaneal pitch, and the talocalcaneal angle were measured on lateral radiographs. In pedobarography, foot pressures were subdivided into eight areas for measurement of contact time, ratio of measured area and to investigate the relation between the degree of the medial deviation of the Center of pressure line and the radiographic measurements. RESULTS: Flat foot group and normal group showed statistically significant difference in every angle measured in lateral radiographs. The foot pressure ratios of the lateral sides in forefoot and the medial and lateral sides of midfoot and the medial side of hindfoot between the flexible flatfoot group and normal group showed statistically significant difference in pedobarography and ratio of contact area in forefoot and hindfoot showed significant change in statistics but no changes in contact time. The relation between pedobarography and radiography was investigated: foot pressure of the medial and lateral side of forefoot and the talocalcaneal angle showed significant relation in statistics and foot pressure of the medial and lateral side of mid foot and every angle measured in lateral radiographs showed significant relation in statistics. Contact time of midfoot and every radiographic value measured in lateral radiograph showed significant relation in statistics and contact area of forefoot and midfoot showed significant relation with every radiographic value measured in lateral radiographs. In addition, medial deviation of center of pressure line showed significant relation in statistics with talus-first metatarsal angle measured on anteroposterior radiographs and talo-horizontal angle and talus-first metatarsal angle measured on lateral radiographs. CONCLUSION: The results of this study showed correlation between radiologic methods and pedobarography in diagnosis of pediatric flexible flatfoot and pedobarography is an useful tool in quantitative and qualitative analysis of the degree of foot deformity and medial deviation of center of pressure line.

BACKGROUND: Although patients with tuberculous-destroyed lung (TDL) account for a significant proportion of those with chronic airflow obstruction, it is difficult to distinguish patients with airway obstruction due to TDL from patients with pure chronic obstructive pulmonary disease (COPD) on initial presentation with dyspnea. We investigated clinical features differing between (i) patients with TDL and airway obstruction and (ii) those with COPD admitted to the intensive care unit (ICU) due to dyspnea. METHODS: We reviewed the medical records of patients with TDL who had a forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) of <70% on a pulmonary function test (PFT; best value closest to admission) and patients with COPD without a history of pulmonary tuberculosis (TB) who were admitted to the ICU. Ultimately, 16 patients with TDL and 16 with COPD were compared, excluding patients with co-morbidities. RESULTS: The mean ages of the patients with TDL and COPD were 63.7 and 71.2 years, respectively. Mean FVC% (50.4% vs. 71.9%; p<0.01) and mean FEV1% (39.1% vs. 58.4%; p<0.01) were significantly lower in the TDL group than in the COPD group. More frequent consolidation with TB (68.8% vs. 31.3%; p=0.03) and more tracheostomies (50.0% vs. 0.0%; p=0.02) were observed in the TDL than in the COPD group. CONCLUSION: Upon ICU admission, patients with TDL had TB pneumonia more frequently, more diminished PFT results, and more tracheostomies than patients with COPD.

PURPOSE: Although several reports have been published regarding the coexistence of hyperparathyroidism and papillary thyroid carcinomas, concurrence of parathyroid adenoma and papillary thyroid carcinoma is extremely rare. The aim of this study was to describe experiences with concurrent parathyroid adenoma and papillary thyroid carcinoma. METHODS: Seven patients with concurrent parathyroid adenoma and papillary thyroid carcinoma were identified between January 2006 and December 2007, and their medical records were reviewed retrospectively. RESULTS: Of the seven patients identified, three were male and four were female; their mean age was 53.6 years. None of the patients presented with symptomatic hyperparathyroidism preoperatively. On laboratory findings, four patients had mild to moderate hypercalcemia, but serum parathyroid hormone concentrations were high in all patients. Preoperative imaging showed suspicious features of diseased parathyroid glands in four patients; two upon ultrasonography and computed tomography together and two upon ultrasonography only. The coexistence of parathyroid adenoma did not affect the extent of thyroid surgery. Laboratory values after surgery returned to within normal ranges in all patients. CONCLUSION: It is important not only to analyze serum calcium levels but also to carefully interpret imaging studies in order to identify asymptomatic hyperparathyroidism when performing thyroid cancer surgery.
