RESUMO
Objective@#To analyze the changes in muscle mass and quality with time on the paretic and non-paretic sides in subacute stroke patients and identify correlations between the variation of muscle mass and quality and lower limb functions. @*Methods@#Thirty hemiplegia patients diagnosed with stroke participated in this study. To evaluate poststroke muscle changes, longitudinal measurement of muscle mass and quality was conducted with bilateral lower limbs. The elastic shear modulus was measured using shear wave elastography and muscle thickness (MT) of rectus femoris, vastus intermedius, vastus lateralis (VL), vastus medialis, tibialis anterior, and gastrocnemius (GCM) muscles. Functional evaluation was performed using Berg Balance Scale (BBS), Five Times Sit to Stand Test (FTSST). Follow-up was performed at discharge. The muscle mass and quality were compared according to time. We analyzed whether muscle quantity and quality were related to function. @*Results@#MT demonstrated no significant change with time. The elastic shear modulus increased significantly in the paretic VL and GCM muscles and did not change significantly in the muscles on the non-paretic side. Correlation analysis detected that elastic shear modulus in the VL has a cross-sectional negative relationship between BBS and positive relationship between FTSST. There were significant correlation between variation of FTSST and the variation of the elastic shear modulus in VL. @*Conclusion@#Only paretic VL and GCM muscle quality changed in subacute stroke patients and muscle’s property related to lower limb functions. Therefore, the lower extremity requires an approach to muscle quality rather than quantity for subacute stroke patients.
RESUMO
Kennedy’s disease (KD) or bulbospinal muscular atrophy is an uncommon x-linked recessive genetic disorder. Its diagnosis is challenging due to its wide array of clinical manifestations and difficulty distinguishing it from other motor neuron diseases.Thus, diagnosis is confirmed through DNA testing. 52-year-old male patient presented to the hospital with chronic low back pain (LBP) and muscle weakness. The patient had mild weakness in some proximal muscles, increased deep tendon reflex.Lumbar spine magnetic resonance imaging (MRI) showed degenerative changes. Motor nerve conduction test results showed close to the normal. Sensory nerve conduction test results showed decreased latency and amplitude in most nerves. Needle electromyography revealed fasciculation potentials, diffuse fibrillation potentials, and positive sharp waves were detected. Thus, molecular genetic testing was performed. Consequently, KD was diagnosed. These results suggest the importance of detailed history taking and neurological examination even for patients with chronic LBP to rule out severe diseases.
RESUMO
Background@#Hydrocele on the contralateral side after surgical repair is an uncommon condition compared to surgical site recurrence. Although there has been much research on metachronous contralateral inguinal hernia in children, metachronous contralateral hydrocele, which share a common pathology with inguinal hernias, has not yet been investigated. We have investigated the incidence and risk factors for metachronous contralateral occurrence of communicating and noncommunicating hydroceles in children younger than 8 years. @*Methods@#From January 2017 to June 2020, 302 children younger than 8 who were diagnosed with unilateral hydroceles were treated in our hospital without surgical exploration of contralateral hydrocele. The disease was classified into communicating and noncommunicating hydroceles. We divided patients into two groups according to the presence of metachronous contralateral hydrocele and analyzed the differences between the two groups. @*Results@#Among 302 patients, the mean age was 36.4 ± 20.9 months. Metachronous contralateral hydrocele occurred in 15 (4.9%) patients as communicating hydroceles.Comparison between the two groups showed statistically significant differences in type of hydrocele (P = 0.047) at first diagnosis. @*Conclusion@#Clinically evident risk of metachronous contralateral hydrocele after unilateral hydrocelectomy was 4.9%. Despite the relatively low incidence rate, the risk of metachronous contralateral occurrence should always be consulted with parents before surgical treatment of hydroceles.
RESUMO
Background@#The existing literature has comprehensively examined the benefits of specialized wound-care services and multidisciplinary team care. However, information on the development and integration of wound-dressing teams for patients who do not require specialized wound care is scarce. Therefore, the present study aimed to elucidate the benefits of a wound-dressing team by reporting our experiences with the establishment of a wounddressing team. @*Methods@#The wound-dressing team was established at Korea University Guro Hospital.Between July 2018 and June 2022, 180,872 cases were managed for wounds at the wounddressing team. The data were analyzed to assess the types of wounds and their outcomes.In addition, questionnaires assessing the satisfaction with the service were administered to patients, ward nurses, residents/internists, and team members. @*Results@#Regarding the wound type, 80,297 (45.3%) were catheter-related, while 48,036 (27.1%), 26,056 (14.7%), and 20,739 (11.7%) were pressure ulcers, dirty wounds, and simple wounds, respectively. In the satisfaction survey, the scores of the patient, ward nurse, dressing team nurse, and physician groups were 8.9, 8.1, 8.2, and 9.1, respectively.Additionally, 136 dressing-related complications (0.08%) were reported. @*Conclusion@#The wound dressing team can enhance satisfaction among patients and healthcare providers with low complications. Our findings may provide a potential framework for establishing similar service models.
RESUMO
Background@#It is quite difficult to distinguish retractile testis from gliding testis, which requires different treatment planning in the clinic setting. We evaluated practice patterns of urologists in Korea regarding the diagnosis and management of retractile and gliding testes. @*Methods@#We mailed or e-mailed self-completion questionnaires consisting of 20 items to 106 urologists practicing in Korean hospitals concerning the diagnosis and treatment of cryptorchidism. We collected and analyzed the responses statistically. @*Results@#Responses were received from 62 urologists. The response rate was 58.5%. Thirtyseven urologists (59.7%) actually felt they had difficulty in distinguishing retractile testis from gliding testis in the clinic setting. This rate was higher for non-pediatric urologists (78.1%) than for pediatric urologists (40.0%) (P = 0.006). In cases of infant retractile testis, only five urologists (8.1%) said that they would perform orchiopexy immediately, with 54 (87.1%) urologists saying they would do follow-up. In cases of preschool-age children with retractile testis, 17 urologists (27.4%) said that they would perform orchiopexy immediately with 41 (66.1%) urologists saying they would do follow-up. In cases of infant gliding testis, 37 urologists (59.7%) said that they would perform orchiopexy immediately with 24 (38.7%) urologists saying they would do a follow-up. @*Conclusion@#More than half (59.7%) of Korean urologists revealed it challenging to distinguish retractile testis and gliding testis in the clinical setting. The more it was difficult to diagnose retractile testis with certainty, the more frequent surgical correction was chosen for treatment. Therefore, it is essential to prevent unnecessary surgical treatment by establishing a practical guideline.
RESUMO
Except for carbamazepine for trigeminal neuralgia, gabapentinoid anticonvulsants have been the standard for the treatment of neuropathic pain. Pregabalin, which followed gabapentin, was developed with the benefit of rapid peak blood concentration and better bioavailability. Mirogabalin besylate (DS-5565, Tarlige® ) shows greater sustained analgesia due to a high affinity to, and slow dissociation from, the α2 δ-1 subunits in the dorsal root ganglion (DRG). Additionally, it produces a lower level of central nervous system-specific adverse drug reactions (ADRs), due to a low affinity to, and rapid dissociation from, the α2 δ-2 subunits in the cerebellum. Maximum plasma concentration is achieved in less than 1 hour, compared to 1 hour for pregabalin and 3 hours for gabapentin. The plasma protein binding is relatively low, at less than 25%. As with all gabapentinoids, it is also largely excreted via the kidneys in an unchanged form, and so the administration dose should also be adjusted according to renal function. The equianalgesic daily dose for 30 mg of mirogabalin is 600 mg of pregabalin and over 1,200 mg of gabapentin. The initial adult dose starts at 5 mg, given orally twice a day, and is gradually increased by 5 mg at an interval of at least a week, to 15 mg. In conclusion, mirogabalin is anticipated to be a novel, safe gabapentinoid anticonvulsant with a greater therapeutic effect for neuropathic pain in the DRG and lower ADRs in the cerebellum.
RESUMO
Mesenchymal stem cell (MSC)-based therapy using gene delivery systems has been suggested for degenerative diseases. Although MSC-based clinical applications are effective and safe, the mode of action remains unclear. Researchers have commonly applied viral-based gene modification because this system has efficient vehicles. While viral transfection carries many risks, such as oncogenes and chromosomal integration, nonviral gene delivery techniques are less expensive, easier to handle, and safe, although they are less efficient. The electroporation method, which uses Nucleofection technology, provides critical opportunities for hard-to-transfect primary cell lines, including MSCs. Therefore, to improve the therapeutic efficacy using genetically modified MSCs, researchers must determine the optimal conditions for the introduction of the Nucleofection technique in MSCs. Here, we suggest optimal methods for gene modification in PD-MSCs using an electroporation gene delivery system for clinical application.

RESUMO
Background and Objectives@#Liver cirrhosis is accompanied by abnormal vascular shunts. The Wnt pathway is essential for endothelial cell survival and proliferation. C-reactive protein (CRP), which is produced by hepatocyte, activates angiogenesis in cardiovascular diseases. @*Methods@#and Results: The expression of CRP in CCl 4 -injured rat livers was detected using qRT-PCR and Western blotting after transplantation of placenta-derived mesenchymal stem cells (PD-MSCs) into rats. To determine whether CRP functions in hepatic regeneration by promoting angiogenesis through the Wnt pathway, we detected VEGF and β-catenin in liver tissues and BrdU and β-catenin in hepatocytes by immunofluorescence. The expression levels of CRP, Wnt pathway-related and angiogenic factors were increased in CCl 4 -injured and PD-MSCs transplanted rat livers. In vitro, the expression levels of Wnt signaling and angiogenic factors were decreased in siRNA-CRP-transfected rat hepatocytes. @*Conclusions@#CRP upregulation by PD-MSCs participates in vascular remodeling to promote liver regeneration via the Wnt signaling pathway during hepatic failure.
RESUMO
Anesthetic experience in frontotemporal dementia (FTD) with severe hypotension associated autonomic dysfunction has not yet been reported. Here in case, we report on the case of treatment with vasopressin to refractory hypotension in FTD patient. A 54-year-old male presented with a ten-year history of FTD with frequent syncope. The patient was scheduled to undergo subtotal gastrectomy for resection of stomach cancer. During the operation, sudden hypotension occurred and it was refractory to fluid and 1 unit of blood resuscitation and did not respond to catecholamine. Transesophageal echocardiography showed normal heart with adequate volume state. After intravenous administration of arginine vasopressin, the patient's vital signs returned to baseline values. Arginine vasopressin might be considered as a valuable alternative for treatment of severe refractory hypotension in autonomic dysfunction patients with FTD.

BACKGROUND: Venous thromboembolism (VTE) is a common and life-threating condition in cancer patients. Low molecular weight heparins (LMWH), such as dalteparin, are recommended in the treatment of VTE. Also, rivaroxaban, an orally administered direct factor Xa inhibitor, was approved for the treatment of VTE. It showed similar efficacy to standard therapy (LMWH or warfarin) and was associated with significantly lower rates of major bleedings. However, in the real world, bleeding has been reported to occur frequently in cancer patient receiving rivaroxaban. The goal of this research was to analyze bleeding risks between rivaroxaban and dalteparin for treatment of VTE in cancer patients. METHODS: Medical records of oncology patients who were treated with rivaroxaban or dalteparin for VTE from July 2012 to June 2014 were retrospectively reviewed. Data collected were as follows: age, sex, weight, height, cancer types and stages, ECOG (eastern cooperative oncology group) PS (performance score), VTE types, concurrently used medications, study drug information (dose and duration of therapy), INR (international normalized ratio), PT (prothrombin time), and platelet counts. Bleeding was classified into major bleedings, clinically relevant non-major bleedings, and minor bleedings. RESULTS: A total of 399 patients were included in the study. Of these patients, 246 were treated with rivaroxaban and 153 with dalteparin. Bleeding rates were significantly higher in the rivaroxaban group than in the dalteparin group (adjusted odds ratio (AOR) 2.09, 95% CI 1.22-3.60) after adjusting for confounders. In addition, rivaroxaban remained independently associated with 1.78-fold (95% CI 1.14-2.76) shorter time to bleeding compared to dalteparin after adjusting other factors known to be associated with poor outcomes. CONCLUSION: This study suggested that rivaroxaban was associated with an increased risk of bleedings in cancer patients.

Hemophagocytic lymphohistiocytosis (HLH) occurs in the primary form (genetic or familial) or secondary form (acquired). The familial form of HLH (FHL) is a potentially fatal autosomal recessive disorder that occurs because of constitutional defects in cell-mediated cytotoxicity. Here, we report a fatal neonatal case of type 2 FHL (FHL2) that involved a novel frameshift mutation. Clinically, the newborn presented with severe sepsis-like features and required mechanical ventilation and continuous venovenous hemodiafiltration. Flow cytometry analysis showed marked HLH and complete absence of intracytoplasmic perforin expression in cytotoxic cells; therefore, we performed molecular genetic analyses for PRF1 mutations, which showed that the patient had a compound heterozygous mutation in PRF1, that is, c.65delC (p.Pro22Argfs*2) and c.1090_1091delCT (p.Leu364Glufs*93). Clinical and genetic assessments for FHL are required for neonates with refractory fever and progressive multiple organ failure, particularly when there is no evidence of microbiological or metabolic cause.

Lidocaine is a commonly used local anesthetic for dental treatment. Urticaria caused by lidocaine has seldom been reported. Generally, urticaria immediately develops after exposure to a causative agent and is considered a manifestation of IgE-mediated hypersensitivity. However, delayed urticaria caused by local anesthetics was reported to be related to cell mediated hypersenstivity. A 3-year old girl visited our allergy clinic due to delayed urticaria after local administration of lidocaine. Both skin prick and intradermal tests with lidocaine revealed negative reactions. However, the provocation test with subcutaneous injection of lidocaine showed urticaria 7 hours after test. In order to identify alternative local anesthetic for the subsequent dental procedure, we performed skin prick, intradermal and provocation tests with procaine, a local anesthetic of the other class, all of which showed negative results. Therefore, we recommended procaine as an alternative local anesthetic, and the patient was successfully treated with procaine. To the best of our knowledge, this is the first case of delayed urticaria caused by lidocaine in Korea.

PURPOSE: The aim of this study was to describe the clinical manifestations and radiologic characteristics of patients with hypothalamic hamartoma (HH) and to delineate various treatment modalities.METHODS: We retrospectively reviewed the medical records of 11 patients with HH at Samsung Seoul Hospital between 1997 and 2013.RESULTS: Mean age of diagnosis was 2.7 years. Seven patients had intractable epilepsy, seven exhibited precocious puberty, and four had both. Gelastic seizure was the most common seizure and was intractable to medications. The patients with the intrahypothalamic type (18.2%) had no precocious puberty, while those with the parahypothalamic type (36.4%) didn't have seizures. Patients (n=6) with intractable epilepsy underwent gamma-knife radiosurgery (GKS); five of these patients responded to this treatment.CONCLUSIONS: The most frequent presenting symptoms of HH were gelastic seizure and precocious puberty. The location and size of tumor defined by brain magnetic resonance imaging affected presenting symptoms and the selection of surgical treatment. GKS can be considered if the patients showed intractable epilepsy and the size of tumor is less than 2 cm in diameter.

BACKGROUND/AIMS: Eradication of Helicobacter pylori is widely accepted as initial therapy for low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, approximately 20% of patients with this disease are not responsive to H. pylori eradication therapy. The aim of this study was to assess remission and relapse rates of low-grade gastric MALT lymphoma after H. pylori eradication and identify the clinical factors that affect remission. METHODS: Thirty-nine patients diagnosed with gastric MALT lymphoma (May 2003 to May 2010) were retrospectively analyzed. RESULTS: Of the 39 patients, 30 (77%) had a H. pylori infection. There were 35/39 (90%) patients with stage I. Among stage I, 25 patients with the infection underwent eradication therapy and 22/25 (88%) achieved remission. The total regression rate with eradication only in stage I was 24/28 (86%). The median time to remission was 98 days (range, 22 to 397 days). Age, tumor location, invasion depth, H. pylori burden, and severity of mononuclear leukocyte and neutrophil infiltration were not related to remission. However, patients with less neutrophil infiltration were more likely to achieve a successful first H. pylori eradication (p=0.049). CONCLUSIONS: The results show that the rate of low-grade gastric MALT lymphoma regression (86%) with H. pylori eradication alone was higher than that in Western studies (77.8%) and that neutrophil infiltration was inversely related to success of the first H. pylori eradication procedure.

BACKGROUND/AIMS: Ecabet sodium is known for its bactericidal effect against H. pylori. It was reported that a supplement of ecabet sodium to conventional triple therapy showed good results in Asia. The Aim of this study was to ascertain the efficacy of additional ecabet sodium on conventional triple therapy for eradication of H. pylori. METHODS: We reviewed the cases of 111 patients (Group A) with H. pylori infection who received ecabet sodium with triple therapy (20 mg of rabeprazole, 1 g of amoxicillin, 500 mg of clarithromycin and 1 g of ecabet sodium, twice daily for 7 days). Another 186 patients (Group B) received PPI-based triple therapy (same as the above, except without the ecabet sodium). Eradication was evaluated 4 weeks later after completion of treatment by 13C-UBT. RESULTS: Eradication rates were 74.8% (83/111) in group A and 70.4% (131/186) in group B by intention-to-treat analysis (p=0.420), and 75.2% (82/109) in group A and 70.7% (128/181) in group B by per protocol analysis (p=0.405). CONCLUSIONS: The addition of ecabet sodium to conventional triple therapy did not increase the eradication rate of H. pylori in this study. These findings imply that ecabet sodium as an additional agent cannot overcome antibiotic resistance, which is the most important cause of failure of triple therapy.

BACKGROUND/AIMS: This study was performed to compare the prevalence rates of primary antibiotic resistance in Helicobacter pylori (H. pylori) isolates among different regions of Korea. METHODS: H. pylori were isolated from gastric mucosal biopsy specimens of 99 Koreans who lived in Gyeonggi (n=40), Kangwon province (n=40) and Busan (n=19) from April to August in 2008. All the patients had no history of H. pylori eradication therapy. The susceptibilities of the H. pylori isolates to amoxicillin, clarithromycin, metronidazole, tetracycline, azithromycin, ciprofloxacin, levofloxacin, and moxifloxacin were tested according to the agar dilution method. RESULTS: There was a difference in resistance to clarithromycin in three institutes located among Gyeonggi (32.5%), Kangwon province (12.5%) and Busan (42.1%) by One way ANOVA test (p=0.027) and nonparametric Kruskal Wallis test (p=0.027). However, by post-hoc analysis, there was no statistically significant difference among three regions. Similarly, the other 7 antibiotics (amoxicillin, metronidazole, tetracycline, azithromycin, ciprofloxacin, levofloxacin and moxifloxacin) did not show any significant difference. CONCLUSIONS: There was no significant regional difference of the primary antibiotic resistance of H. pylori. However, the included patient number might not be enough for this conclusion demanding further evaluations.

BACKGROUND/AIMS: This study was performed to evaluate whether the prevalence rates of primary antibiotic resistance in Helicobacter pylori (H. pylori) isolates and the eradication rate of H. pylori could be different between cancer and non-cancer patients. METHODS: H. pylori were isolated from gastric mucosal biopsy specimens obtained from 269 Koreans, who did not have any eradication therapy history and were diagnosed as one of the following diseases; chronic gastritis, benign gastric ulcer, duodenal ulcer or gastric cancer. The susceptibilities of the H. pylori isolates to amoxicillin, clarithromycin, metronidazole, tetracycline, azithromycin, ciprofloxacin, levofloxacin and moxifloxacin were examined with the agar dilution method. In addition, eradication rate of H. pylori was evaluated. RESULTS: There was no significant difference in the primary antibiotic resistance to above eight antibiotics among chronic gastritis, peptic ulcer disease and gastric cancer. Furthermore there was no difference of antibiotic resistance between cancer and non-cancer patients, and there was no difference of eradication rate of H. pylori according to disease. CONCLUSIONS: Primary antibiotic resistance and H. pylori eradication rate were not different between cancer and non-cancer patients.
