RESUMO
BACKGROUND: The novel coronavirus (COVID-19) that emerged in 2019 and spread globally in 2020 has resulted in the imposition of lockdowns or a state of emergency in many cities worldwide. In Japan, a "new lifestyle" is being advocated. We hypothesize that the new lifestyle has changed people's use of their upper limbs during the COVID-19 pandemic. Therefore, through this questionnaire study, we aimed to determine the factors associated with exacerbation of symptoms during the pandemic and to investigate the current status of patients who require hand surgery. METHODS: This study was a prospective multi-center questionnaire survey. This study was conducted in Japan from December 2020 to July 2021 at university and general hospitals in nine prefectures. A questionnaire was administered to patients who visited a hospital with symptoms of nerve entrapment syndrome, osteoarthritis, or tenosynovitis. RESULTS: A total of 502 patients with a mean age of 63.8 years responded. The 240 patients who experienced exacerbation (exacerbated and markedly exacerbated) were compared with other patients (unchanged, improved, and markedly improved). An increase in the time spent on personal computers and smartphones was associated with exacerbation of hand symptoms. Patients who wanted to undergo surgery but were postponed due to COVID-19 accounted for 23.5% of the outpatients. The mean scores for pain, jitteriness, and anxious depression in these patients were significantly higher than those of patients who did not want surgery. CONCLUSIONS: Our results suggest that an increase in the time spent on personal computers and smartphones is associated with exacerbation of hand symptoms during the COVID-19 pandemic. Patients who wanted to undergo surgery but were postponed by COVID-19 experienced greater pain, jitteriness, and anxious depression.

Tuberculosis (TB) treatment is long and requires multiple drugs, likely due to various phenotypes of TB bacilli with variable drug susceptibilities. Drugs with broad activity are urgently needed. This study aimed to evaluate delamanid's activity against growing or dormant bacilli in vitro as well as in vivo Cultures of Mycobacterium bovis BCG Tokyo under aerobic and anaerobic conditions were used to study the activity of delamanid against growing and dormant bacilli, respectively. Delamanid exhibited significant bactericidal activity against replicating and dormant bacilli at or above concentrations of 0.016 and 0.4 mg/liter, respectively. To evaluate delamanid's antituberculosis activity in vivo, we used a guinea pig model of chronic TB infection in which the lung lesions were similar to those in human TB disease. In the guinea pig TB model, a daily dose of 100 mg delamanid/kg of body weight for 4 or 8 weeks demonstrated strong bactericidal activity against Mycobacterium tuberculosis Importantly, histological examination revealed that delamanid killed TB bacilli within hypoxic lesions of the lung. The combination regimens containing delamanid with rifampin and pyrazinamide or delamanid with levofloxacin, ethionamide, pyrazinamide, and amikacin were more effective than the standard regimen (rifampin, isoniazid, and pyrazinamide). Our data show that delamanid is effective in killing both growing and dormant bacilli in vitro and in the guinea pig TB model. Adding delamanid to current TB regimens may improve treatment outcomes, as demonstrated in recent clinical trials with pulmonary multidrug-resistant (MDR) TB patients. Delamanid may be an important drug for consideration in the construction of new regimens to shorten TB treatment duration.

The purpose of this study was to quantitatively evaluate Akahori's preoperative classification of cubital tunnel syndrome. We analyzed the results for 57 elbows that were treated by a simple decompression procedure from 1997 to 2004. The relationship between each item of Akahori's preoperative classification and clinical stage was investigated based on the parameter distribution. We evaluated Akahori's classification system using multiple regression analysis, and investigated the association between the stage and treatment results. The usefulness of the regression equation was evaluated by analysis of variance of the expected and observed scores. In the parameter distribution, each item of Akahori's classification was mostly associated with the stage, but it was difficult to judge the severity of palsy. In the mathematical evaluation, the most effective item in determining the stage was sensory conduction velocity. It was demonstrated that the established regression equation was highly reliable (R = 0.922). Akahori's preoperative classification can also be used in postoperative classification, and this classification was correlated with postoperative prognosis. Our results indicate that Akahori's preoperative classification is a suitable system. It is reliable, reproducible and well-correlated with the postoperative prognosis. In addition, the established prediction formula is useful to reduce the diagnostic complexity of Akahori's classification.

We report a case of 4th metacarpal head collapse of a 19-year-old healthy man. MRI revealed T1 low and T2 high regions in the collapsed 4th metacarpal head, as well as in the right 3rd and left 4th metacarpal head. Our initial diagnosis was occult compression fracture due to avascular necrosis, known as Dieterich's disease. However, pathological findings of surgically resected right 4th metacarpal head were compatible with transient osteoporosis and metacarpal head fracture followed by active tissue repair. The autologous osteochondral transplants from costchondral junction survived and maintained their size and shape even at 10-year follow-up.

We biomechanically evaluated the bone fixation rigidity of an ONI plate (Group I) during fixation of experimentally created transcondylar humerus fractures in cadaveric elbows, which are the most frequently observed humeral fractures in the elderly, and compared it with the rigidity achieved by 3 conventional fixation methods:an LCP reconstruction plate 3.5 using a locking mechanism (Group II), a conventional reconstruction plate 3.5 (CRP) with a cannulated cancellous screw (Group III), and a CRP with 2 cannulated cancellous screws (CS) in a crisscross orientation (Group IV). In the axial loading test, the mean failure loads were:Group I, 98.9+/-32.6;Group II, 108.5+/-27.2;Group III, 50.0+/-7.5;and Group IV, 34.5+/-12.2 (N). Group I fixations failed at a significantly higher load than those of Groups III and IV (p<0.05). In the extension loading test, the mean failure loads were:Group I, 34.0+/-12.4;Group II, 51.0+/-14.8;Group III, 19.3+/-6.0;and Group IV, 14.7+/-3.1 (N). Group IV fixations showed a significantly lower failure load than those of Group I (p<0.05). The fixation rigidities against mechanical loading by the ONI plate and LCP plate were comparable. These results suggested that an ONI system might be superior to the CRP and CS method, and comparable to the LCP method in terms of fixation rigidity for distal humerus fractures.

In the course of our search for anti-microbial agents against dormant Mycobacterium tuberculosis, halicyclamine A was re-discovered as a lead for anti-tuberculosis agent from a marine sponge of Haliclona sp. on the guidance of the constructed bioassay. Halicyclamine A showed growth inhibition against Mycobacterium smegmatis, Mycobacterium bovis BCG, and M. tuberculosis H37Ra with MICs in the range of 1.0-5.0microg/ml under both aerobic condition and hypoxic condition inducing dormant state. The growth-inhibitory activity of halicyclamine A was bactericidal, and halicyclamine A did not exhibit cross-resistance with the currently used anti-tuberculosis drugs of isoniazid, ethambutol, rifampicin, and streptomycin. Halicyclamine A has been isolated originally as one of the active constituents inhibiting inosine 5'-monophosphate dehydrogenase (IMPDH). Then, in order to elucidate action-mechanism of halicyclamine A, we prepared IMPDH over-expressing strains of M. smegmatis. However, IMPDH was not target for halicyclamine A, because halicyclamine A showed same MIC value against the wild-type M. smegmatis and IMPDH over-expressing strains.

BACKGROUND: Tuberculosis (TB) is still a leading cause of death worldwide. Almost a third of the world's population is infected with TB bacilli, and each year approximately 8 million people develop active TB and 2 million die as a result. Today's TB treatment, which dates back to the 1970s, is long and burdensome, requiring at least 6 mo of multidrug chemotherapy. The situation is further compounded by the emergence of multidrug-resistant TB (MDR-TB) and by the infection's lethal synergy with HIV/AIDS. Global health and philanthropic organizations are now pleading for new drug interventions that can address these unmet needs in TB treatment. METHODS AND FINDINGS: Here we report OPC-67683, a nitro-dihydro-imidazooxazole derivative that was screened to help combat the unmet needs in TB treatment. The compound is a mycolic acid biosynthesis inhibitor found to be free of mutagenicity and to possess highly potent activity against TB, including MDR-TB, as shown by its exceptionally low minimum inhibitory concentration (MIC) range of 0.006-0.024 microg/ml in vitro and highly effective therapeutic activity at low doses in vivo. Additionally, the results of the post-antibiotic effect of OPC-67683 on intracellular Mycobacterium tuberculosis showed the agent to be highly and dose-dependently active also against intracellular M. tuberculosis H37Rv after a 4-h pulsed exposure, and this activity at a concentration of 0.1 microg/ml was similar to that of the first-line drug rifampicin (RFP) at a concentration of 3 microg/ml. The combination of OPC-67683 with RFP and pyrazinamide (PZA) exhibited a remarkably quicker eradication (by at least 2 mo) of viable TB bacilli in the lung in comparison with the standard regimen consisting of RFP, isoniazid (INH), ethambutol (EB), and PZA. Furthermore, OPC-67683 was not affected by nor did it affect the activity of liver microsome enzymes, suggesting the possibility for OPC-67683 to be used in combination with drugs, including anti-retrovirals, that induce or are metabolized by cytochrome P450 enzymes. CONCLUSIONS: We concluded that based on these properties OPC-67683 has the potential to be used as a TB drug to help combat the unmet needs in TB treatment.

In an effort to develop potent new antituberculosis agents that would be effective against both drug-susceptible and drug-resistant strains of Mycobacterium tuberculosis, we prepared a novel series of optically active 6-nitro-2,3-dihydroimidazo[2,1-b]oxazoles substituted at the 2-position with various phenoxymethyl groups and a methyl group and investigated the in vitro and in vivo activity of these compounds. Several of these derivatives showed potent in vitro and in vivo activity, and compound 19 (OPC-67683) in particular displayed excellent in vitro activity against both drug-susceptible and drug-resistant strains of M. tuberculosis H37Rv (MIC = 0.006 microg/mL) and dose-dependent and significant in vivo efficacy at lower oral doses than rifampicin in mouse models infected with M. tuberculosis Kurono. The synthesis and structure-activity relationships of these new compounds are presented.

The challenges in preventing and controlling tuberculosis are further complicated by the deadly rise of multi-drug-resistant tuberculosis (MDR-TB). Recognizing the seriousness of the situation, we initiated a program to screen new agents that would satisfy these unmet needs and have a favorable safety profile. Mycobacteria are well known for their lipid-rich properties. In Mycobacterium tuberculosis, mycolic acid in particular has been established the wall component related to the pathogenesis in the host. There are approximately 250 identified genes related to biosynthesis of the lipid turnover that contain InhA, the main target of isoniazid. Thus, the logical approach for developing a chemotherapy agent against tubercle bacilli included screening compounds that could inhibit the biosyntheses of mycolic acid and that had a novel chemical structure to ensure improved efficacy against MDR-TB. Some of the screening systems established for those purposes and some of the candidates are outlined.

BACKGROUND: A facile electromyographic test in the outpatient clinic is needed to evaluate the outcome of screening for carpal tunnel syndrome. The purpose of the current prospective study was to compare the accuracy of Nervepace digital electroneurometer (Nervepace) and Dantec Neuromatic 2000M (Dantec) measurements of a wide range of distal motor latency (DML) of the median nerve. METHODS: The DML values for 112 of 126 median nerves examined with Nervepace and conventional electromyography, Dantec were statistically analyzed in this prospective study. The 30 hands of 15 clinically healthy adults 20-24 years old served as the reference group. Sixty consecutive patients (96 hands) with idiopathic carpal tunnel syndrome provided a wider range of DML values. All of the patients had standard clinical tests and standard motor (Dantec and Nervepace) and sensory (Dantec) electrodiagostic tests before endoscopic carpal tunnel release. RESULTS: The DML was measurable in all 30 hands of the reference group, in all 96 hands of the patients by Dantec, but in only 82 hands (52 patients) by Nervepace. Nervepace and Dantec DML values of 6.0 ms or less had high correlation and agreement. CONCLUSIONS: Correlation and agreement decreased significantly among values greater than 6.0 ms.

The purpose of this study was to present a new internal fixation technique for transcondylar fractures of the humerus in elderly patients. Seventeen patients, aged older than 70 years, with displaced transcondylar fractures were treated by our new surgical method. All fractures were fixed by a customized AO small T plate and a transcondylar screw passed from the lateral epicondyle to the medial wall of the trochlea across the humeral condyle. The plate was hand-shaped, trimmed, and applied at the lateral side of the fracture site, and either a cannulated cancellous screw or an AO one-third tubular plate was applied at the medial side of the fracture site. All patients in this study had osteoporotic bone and a small distal fragment. They were followed up for a mean of 30 months (range, 24 to 60 months). Radiographically, union was achieved completely in all patients, and all except 1 had maintained the postoperative alignment. Bone graft or cement fixation was not required in any case. The assessment of the results by use of the modified Cassebaum's rating scale was excellent in 3 cases, good in 11, and fair in 3. With the custom AO small T plate and transcondylar screw fixation technique, the screw that passes through the humeral condyle provides good stability even in cases with a small osteoporotic fragment of the distal humerus. The screw does not damage the articular surface of the elbow joint, and stable fixation can be obtained even in osteoporotic bone.

A 54-year-old woman who had been treated for rheumatoid arthritis for 12 years developed spontaneous multiple flexor tendon ruptures during a 5-month period. Radiography revealed volar subluxation of the lunate bone. Surgery was performed 5 months after the first onset of tendon rupture. All eight flexors, except the flexor pollicis longus tendons, had ruptured, and the damage resembled spaghetti. Four flexor digitorum profundus tendons were reconstructed by bridge graft using their respective sublimis tendons. Wrist joint fusion and tenolysis were performed 3 months after the first operation. Each finger achieved a good range of motion 2 years and 6 months after the second operation.
RESUMO
Fracture-dislocations of the coronoid and olecranon were produced experimentally, and their onset mechanisms were analyzed to clarify the effects of compression force on the coronoid and olecranon. The study used two-dimensional finite element method (2D-FEM) simulations and static loading experiments. The latter applied axial force distally to 40 cadaveric elbows. Posterior fracture-dislocations occurred between 15 degrees of extension and 30 degrees of flexion, anterior or posterior fracture-dislocations at 60 degrees, and only anterior fracture-dislocations at 90 degrees. Injuries were mainly to anterior or posterior support structures. The 2D-FEM simulations showed that the stress concentration areas moved from the coronoid process to the olecranon as position changed from extension to flexion. The very high frequency of concurrent fracture-dislocations of radial head or neck in the current study indicated that the radial head may also function as a stabilizer in the anterior support system.

Radio-lunate limited arthrodesis (RLA) is an established surgical intervention for damaged rheumatoid arthritis (RA) wrists. The goal of RLA is to conserve the range of motion (ROM) and level of activities of daily life (ADL) by delaying more extensive fusion. In this study, we retrospectively reviewed the outcome of RLA with ulnar head resection (UHR) in terms of pain score, ROM, and radiographic parameters, including carpal height ratio, ulnar translation ratio, and palmar subluxation. The clinical factors, such as dose of corticosteroids per day and laboratory examination data before surgery, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and rheumatoid factor (RF), did not influence the results of the surgery. The changes in these clinical factors were also statistically analyzed in relation to the Schulthess classification of preoperative radiographs of wrists reported by Simmen and Huber: Type I (ankylosis type), Type II (osteoarthritis type), and Type III (disintegration type). This study hypothesized that RLA with UHR would provide no significant improvement in Type III wrists. The results showed that RLA with UHR resulted in stable wrists with excellent pain relief and with limited, but temporary, functional ROM, suggesting that this procedure seems to be applicable for all types of wrists within this group of patients.
RESUMO
Stress distribution in the humeroradial joint was analyzed with pressure-sensitive film, a tactile sensor, and by the three-dimensional finite element method. Fifteen cadaveric elbows with minimal osteoarthritic changes were loaded perpendicular to the articular surface of the radial head in the full pronation, supination, and neutral positions from 0 degrees to 90 degrees. Finite element analysis of stress distribution in the joint was based on a model of the same conditions. The patterns of stress distribution were similar with all three analysis methods. High stress was concentrated laterally in supination, and medially in the neutral and pronation positions. The results of the analyses closely resembled those found in some studies of the pathophysiology of degenerative changes in the humeroradial joint.

Nerve conduction studies performed between 1994 and 1996 on the median nerves of 204 hands of 113 patients [20 patients in hemodialysis (HD) with diabetic nephropathy, 27 without diabetes mellitus in HD for 10 years or more, 18 without diabetes mellitus in HD for less than 10 years, and 48 with diabetes mellitus not undergoing HD] were reviewed retrospectively to develop a discriminating tool that would better inform treatment selection for patients with carpal tunnel syndrome (CTS) in HD. Scatter diagrams were drawn from the results of this study, and a regression formula was obtained. Among the long-term HD patients without diabetic nephropathy, distal motor latency (DML) tended to increase without a significant concomitant reduction in motor nerve conduction velocity (MCV) in the forearm. In contrast, in HD patients with diabetic nephropathy, DML tended to increase and MCV was significantly lower despite shorter HD periods. The study showed that in HD patients, in whom the MCV(m/s) > 11[9 - DML(ms)], the surgical results might be excellent or good. The formula was tested against the results of the 30 surgical cases. The sensitivity of this formula was 0.84, and the specificity was 1.00. The formula produced a predictor of surgical results when used in conjunction with other criteria for CTS in HD patients, especially those with diabetic nephropathy.

In almost all the patients over 65 years of age with intracapsular femoral neck fractures who we treated over a 2-year period, we used osteosynthesis with Ace 6.5-mm cannulated cancellous screws. We then followed them for at least 24 months. Each of the seven nondisplaced fractures healed. Of the 20 displaced fractures, 14 were rated as healed, 5 as failures, and 1 as a late segmental collapse. Among the 14 displaced fractures with an operative delay of 1 day, 12 healed, whereas only 2 of the 6 fractures with an operative delay of 2 days or more did so. Of the 12 typical fractures (with a medial spike in the head fragment), 10 healed, as did 4 of the 8 crescent or mixed-type fractures. The treatment of choice for nondisplaced fractures is osteosynthesis. Displaced fractures that occur on the day of operation or the day before should be treated with osteosynthesis if they are the typical type. The rest of the displaced fractures should be considered candidates for primary prosthetic replacement.

The grading system of Hashizume and Hirooka for carpal tunnel syndrome (CTS) was modified to refine the system for surgical treatment selection for specific subsets of CTS in patients with rheumatoid arthritis (RA). The grading system uses clinical signs and symptoms of CTS, including pain indications, to identify surgical subsets of patients to facilitate treatment selection. Retrospective analysis of the system included radiographic and electromyographic findings. Twenty-nine hands of 21 adult patients with CTS in RA were graded in the current study. Eight hands with mild synovitis received conservative treatment only. Endoscopic carpal tunnel release (ECTR), using Okutsu's universal subcutaneous endoscopic system with a clear cannula, was performed in 11 hands with moderate synovitis. Open carpal tunnel release (OCTR) combined with flexor tenosynovectomy was performed in 9 hands with severe synovitis. One more hand required OCTR after ECTR when malignant RA was diagnosed. Clinical results, evaluated using Kelly's criteria, were: excellent in 19 hands, good in 5, fair in 4, and poor in the 1 patient with malignant RA. Clinical symptoms of CTS improved in all but the latter patient. Although the sample size in the current study is small, the results appear to warrant further study to determine the clinical utility of the grading system.

Clinical characteristics, diagnostic imaging, arthroscopic findings, and surgical results of arthroscopic treatment are reported in 62 hands with traumatic triangular fibrocartilage complex (TFCC) injury treated between 1995 and 2002. This retrospective study also describes and compares the results of a novel arthroscopic suture technique for repairing tears with Palmer's class 1B and 1D tears. According to Palmer's classification, there were 10 class 1A, 27 1B, 8 1C, and 17 1D injuries. The arthroscopic suture and débridement treatments were done under brachial plexus block as a 1-day in-hospital procedure. Class 1D tears required transradial fixation to anchor the TFCC. Surgical results of suture groups according to Minami's criteria were excellent in 16 hands, good in 15 hands, fair in 1 hand, and poor in 1 hand. The results of the débridement group were excellent in 16 hands, good in 10 hands, fair in 2 hands, and poor in 1 hand. The results of the current study indicate that the novel suture technique were easy to perform, provided strong, tight repair for class 1D injuries, and was applicable for class 1B injuries in this small case series.
