Perioperative complications and Intensive Care Unit utilization in super-superobese patients undergoing laparoscopic bariatric surgery
Chia-Li Kao, Cheuk-Kwan Sun, Hsiu-Jung Lin, Kuo-Chuan Hung
October-December 2019, 31(4):254-259
DOI:10.4103/tcmj.tcmj_125_18  PMID:31867254
Objective: Anesthetic management for super-superobese (SSO) patients (body mass index [BMI] ≥60 kg/m2) presents a challenge for anesthesiologists. This study aimed at characterizing the early complications and Intensive Care Unit (ICU) utilization in SSO patients receiving laparoscopic bariatric surgery. Materials and Methods: Totally, 25 SSO patients receiving laparoscopic bariatric surgery between June 2006 and December 2011 were reviewed. The data collected included patient demographics, preoperative comorbidities, anesthetic techniques, airway management, perioperative adverse events, ICU utilization, and early complications occurring within 30 days of index surgery. Early complications were defined as the adverse events that led to permanent detrimental effects or required significant additional intervention. Results: A retrospective analysis was performed on data from 25 consecutive SSO patients (age: 31.2 ± 11.1 years; BMI: 64.9 ± 4.7 kg/m2). Tracheal intubation was attempted successfully in all patients but was difficult in two cases when using laryngoscopy. Bronchospasm was observed in five cases (20%) after tracheal intubation. Postoperative ICU utilization was required in five cases (20%). Early complications occurred in two cases during their stay in postanesthesia care unit (including one case of respiratory failure and one case of hyperkalemia) and in two cases during their stay in ICU (both with respiratory failure). The incidence of early complications was 16%. All patients were discharged from the hospital without sequelae. Conclusions: It is imperative to anticipate the potential for developing perioperative adverse events and postoperative complications in SSO patients after bariatric surgery. Appropriate utilization of ICU resources may enhance patient safety.

A review of ovary torsion
Ci Huang, Mun-Kun Hong, Dah-Ching Ding
July-September 2017, 29(3):143-147
DOI:10.4103/tcmj.tcmj_55_17  PMID:28974907
Ovarian torsion is a rare but emergency condition in women. Early diagnosis is necessary to preserve the function of the ovaries and tubes and prevent severe morbidity. Ovarian torsion refers to complete or partial rotation of the adnexal supporting organ with ischemia. It can affect females of all ages. Ovarian torsion occurs in around 2%–15% of patients who have surgical treatment of adnexal masses. The main risk in ovarian torsion is an ovarian mass. The most common symptom of ovarian torsion is acute onset of pelvic pain, followed by nausea and vomiting. Pelvic ultrasonography can provide information on ovarian cysts. Once ovarian torsion is suspected, surgery or detorsion is the mainstay of diagnosis and treatment.

DOI:10.4103/tcmj.tcmj_53_17  PMID:28974905
Recurrent urinary tract infection (UTI) might be one of the most common problems in urological clinics. Recent research has revealed novel evidence about recurrent UTI and it should be considered a different disease from the first infection. The pathogenesis of recurrent UTI might include two mechanisms, bacterial factors and deficiencies in host defense. Bacterial survival in the urinary bladder after antibiotic treatment and progression to form intracellular bacterial communities might be the most important bacterial factors. In host defense deficiency, a defect in pathogen recognition and urothelial barrier function impairment play the most important roles. Immunodeficiency and urogenital tract anatomical abnormalities have been considered the essential risk factors for recurrent UTI. In healthy women, voiding dysfunction and behavioral factors also increase the risk of recurrent UTI. Sexual intercourse and estrogen deficiency in postmenopausal women might have the strongest association with recurrent UTI. Traditional lifestyle factors such as fluid intake and diet are not considered independent risk factors now. Serum and urine biomarkers to predict recurrent UTI from the first infection have also attracted a wide attention recently. Current clinical evidence suggests that serum macrophage colony-stimulating factor and urinary nerve growth factor have potential predictive value for recurrent UTI. Clinical trials have proven the efficacy of the oral immunoactive agent OM-89 for the prevention of UTI. Vaccines for recurrent UTI are recommended by the latest guidelines and are available on the market.

Numerous studies indicate that microbiota plays an important role in human health. Diet is a factor related to microbiota which also influences human health. The relationships between diet, microbiota, and human health are complex. This review focuses on the current literature on vegan diets and their unique impact on gut microbiota. We also report on the health benefits of a vegan diet for metabolic syndrome, cardiovascular disease, and rheumatoid arthritis concerning relevant impacts from gut microbiota. Despite evidence supporting the clinical relevance of vegan gut microbiota to human health, the whole mechanism awaits further investigation.

Neha Dahiya, Kavita Aggarwal, Megha Chandra Singh, Suneela Garg, Rajesh Kumar
October-December 2019, 31(4):240-243
DOI:10.4103/tcmj.tcmj_145_18  PMID:31867252
Objective: Cervical cancer is one of the major concerns of public health importance in today's world. It is a leading cause of mortality in women of reproductive age group worldwide, mainly in developing countries. Reduction in mortality and morbidity due to cervical cancer is possible through early detection and treatment. The major factors influencing the early detection of cervical cancer are knowledge regarding risk factors, screening, Pap smear, and symptoms among women. Materials and Methods: The present cross-sectional study was carried out to assess the knowledge, attitude, and practice of women about the risk factors, symptoms, and prevention of cervical cancer. Data were obtained from 220 women who visited international trade fair using a pretested self-administered questionnaire. Results: Only 75 study women (50.0%) had ever heard of cervical cancer. The knowledge regarding cervical cancer and its various domains was significantly higher in students and unmarried women. The foul-smelling vaginal discharge was the most common early symptom of cervical cancer according to most of the study women (26, 17.3%). Most of the study women (19, 12.7%) reported tobacco and smoking as the most common risk factor associated with cervical cancer. Only 39 women (26%) had ever heard of cervical cancer screening. Only 27 women (18.0%) ever had Pap smear done in the past and 87 women (58.0%) were willing to undergo cervical cancer screening is offered free of cost. Conclusion: The study demonstrates the lack of awareness in women regarding cervical cancer and its screening modalities. This necessitates spreading awareness regarding early symptoms and risk factors associated with cervical cancer for early detection and treatment initiation.

Yu-Chih Shen
July-September 2018, 30(3):141-147
DOI:10.4103/tcmj.tcmj_71_18  PMID:30069121
Depression is the predominant pole of disability in bipolar disorder and compared with mania/hypomania, has less systematic research guiding the development of treatment especially in its acute phase (acute bipolar depression). The deficiency in the management of the acute bipolar depression largely reflects the natural divergence of opinion resulting from significant knowledge gaps. At present, there are only 3 approved drug treatments for acute bipolar depression: olanzapine/fluoxetine combination, quetiapine (immediate or extended release), and lurasidone (monotherapy or adjunctive to lithium or valproate). Nonapproved agents and nonpharmacologic treatment such as lamotrigine, antidepressants, modafinil, pramipexole, ketamine, and electroconvulsive therapy are often prescribed to treat acute bipolar depression. This article discusses the challenges of diagnosing bipolar depression, and reviews above treatment options for acute bipolar depression.

Current pharmacological and surgical treatment of underactive bladder
Yuan-Hong Jiang, Cheng-Ling Lee, Jia-Fong Jhang, Hann-Chorng Kuo
October-December 2017, 29(4):187-191
DOI:10.4103/tcmj.tcmj_122_17  PMID:29296045
Underactive bladder (UAB) or detrusor underactivity (DU) is a common yet still poorly understood urological problem. In addition to true detrusor failure and neuropathy, the inhibitory effects of detrusor contraction by the striated urethral sphincter and the bladder neck through alpha-adrenergic activity may also play a role in the development of UAB or DU. Treatment of UAB or DU aims to reduce the postvoid residual (PVR) urine volume and increase voiding efficiency, either by spontaneous voiding or abdominal straining. Pharmacotherapy with parasympathomimetics or cholinesterase inhibitors might be tried, and benefits can be achieved in combination with alpha-blockers. Bladder outlet surgeries, including urethral onabotulinumtoxinA injection, transurethral incision of the bladder neck, and transurethral incision or resection of the prostate can effectively improve voiding efficiency and decrease the PVR in most patients with DU. The mechanisms have not been well elucidated. It is likely that ablation of the bladder neck or prostatic urethra might not only decrease bladder outlet resistance but also abolish the sympathetic hyperactivity which inhibits detrusor contractility in patients with idiopathic UAB or DU.

Current consensus and controversy on the treatment of male lower urinary tract symptoms/benign prostatic hyperplasia
Chun-Hou Liao, Hann-Chorng Kuo
January-March 2017, 29(1):1-5
DOI:10.4103/tcmj.tcmj_2_17  PMID:28757756
Lower urinary tract symptoms (LUTS) are highly prevalent in men and increase with age. Because LUTS are common among elderly men, they are usually considered synonymous with benign prostatic hyperplasia (BPH). Drugs should be the first-line treatment for BPH and surgical intervention should be performed only when there are complications or LUTS refractory to medical treatment. In addition to medical treatment, several minimally invasive therapies, such as thermal therapy, prostatic lift, laser evaporation, or laser enucleation techniques have been developed. Recent investigations have also revealed that bladder dysfunction such as detrusor overactivity and detrusor underactivity may also contribute to male LUTS. In the treatment of LUTS suggestive of BPH (LUTS/BPH), the following questions should be considered: Is there an obstruction? Are we treating BPH or LUTS? Can management targeting BPH reduce LUTS? Should patients with LUTS be treated before bladder outlet obstruction is confirmed? What is the role of transurethral resection of the prostate (TURP) nowadays? Will new techniques provide better outcomes than TURP? This article discusses the current consensus and controversies in the treatment of LUTS/BPH.

Bertolotti's syndrome in low-backache population: Classification and imaging findings
Reddy Ravikanth, Pooja Majumdar
April-June 2019, 31(2):90-95
DOI:10.4103/tcmj.tcmj_209_17  PMID:31007488
Objective: Lumbosacral transition vertebrae (LSTVs) are associated with alterations in biomechanics and anatomy of spinal and paraspinal structures, which have important implications on surgical approaches and techniques. LSTVs are often inaccurately detected and classified on standard anteroposterior radiographs and magnetic resonance imaging. The use of whole-spine images as well as geometric relationships between the sacrum and lumbar vertebra increases accuracy. The diagnosis of symptomatic LSTV is considered with appropriate patient history and imaging studies. This study aimed to classify the anatomical variations in LSTV and determine, by plain radiography, if there exists a relationship between sacralization and low backache (LBP). Materials and Methods: Five hundred lumbosacral radiographs of LBP patients were examined after obtaining prior consent from the patient and approval from the “institutional ethics committee.” Data collection consisted of the patient's age at the time of imaging gender and number of lumbar vertebral bodies. Dysplastic transverse processes were classified according to the Castellvi radiographic classification system. The incidence of sacralization in patients and the control groups was reported, and the anomaly was compared according to the groups. Results: Of these patient groups, 134 were classified as positive for sacralization, which resulted in an incidence of 26.8%. The most common anatomical variant was Castellvi Type IA (7.6%). There were no statistically significant differences between men and women who had anomaly (P = 0.9256). Higher incidences of Type IB and Type IIB were found in men, but those results were not statistically significant (P = 0.133 and P = 0.581, respectively) when compared with the female group. Daily frequency and intensity of LBP were assessed in patients using visual analog scale (VAS) scores. The patients with LBP and no malformation reported an average pain level on the VAS for pain of 2.2 versus 5.2 in patients with LBP and a transitional vertebra, respectively. Conclusion: Based on our data, we conclude that lumbosacral transitional segments are a common cause in the low-backache population. However, no relationship was found between age and genders in this study. However, in comparison with the nonspecific low-backache group, the VAS scores were significantly higher and the pain duration was significantly longer in the LSTV group.

Medical leadership: An important and required competency for medical students
Tsung-Ying Chen
April-June 2018, 30(2):66-70
DOI:10.4103/tcmj.tcmj_26_18  PMID:29875585
Good medical leadership is the key to building high-quality healthcare. However, in the development of medical careers, the teaching of leadership has traditionally not equaled that of technical and academic competencies. As a result of changes in personal standards, the quality of medical leadership has led to variations between different organizations, as well as occasional catastrophic failure in the standard of care provided for patients. Leaders in the medical profession have called for reform in healthcare in response to challenges in the system and improvements in public health. Furthermore, there has been an increased drive to see leadership education for doctors starting earlier, and continuing throughout their careers so that they can take on more important leadership roles throughout the healthcare system. Being a physician requires not only management and leadership but also the need to transfer competencies to communication and critical thinking. These attributes can be obtained through experience in teamwork under the supervision of teaching staff. Therefore, medical students are expected to develop skills to deal with and resolve conflicts, learn to share leadership, prepare others to help and replace them, take mutual responsibility and discuss their performance.

Assessment of perceived stress and association with sleep quality and attributed stressors among 1st-year medical students: A cross-sectional study from Karwar, Karnataka, India
Clevin Rashmi Rebello, Prasad Budri Kallingappa, Preethi G Hegde
October-December 2018, 30(4):221-226
DOI:10.4103/tcmj.tcmj_85_17  PMID:30305785
Objectives: The objective is to study the extent of perceived stress among 1st-year medical students using the Perceived Stress Scale-14 (PSS-14) and its association with sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI) and attributed stressors. Materials and Methods: A cross-sectional study was conducted of 121 1st-year medical students at Karwar Institute of Medical Sciences, Karwar, Karnataka, India. The extent of their stress was assessed using the PSS-14 and their sleep quality was assessed using the PSQI. Graded stress exerted by the attributed stressors was also assessed. Results: A total of 33.8% of participants had perceived stress scores of >28. Among academic stressors, performance in examinations (34.7%), lack of time for recreation (30.6%), curriculum (24.8%), and frequency of examinations (24.8%) were the highest rated stressors. Quality of food in the mess (50.4%) and lack of entertainment in the institution (39.7%) were the highest rated psychosocial stressors. There was a positive correlation between the PSS-14 scores and various academic stressors and the global PSQI score. Conclusion: First-year medical students reported a high level of stress, including academic and psychosocial stressors. Effective changes in the curriculum and living conditions can reduce the level of stress among these students.

Tao-Yang Wei, Pang-Hsin Hsueh, Shu-Hui Wen, Chien-Lin Chen, Chia-Chi Wang
July-September 2019, 31(3):169-176
DOI:10.4103/tcmj.tcmj_48_18  PMID:31258293
Objective: The incidence of gastroesophageal reflux disease (GERD) is increasing, and the disease has a close association with dietary habits. This study aims to investigate the role of tea and coffee drinking in the development of GERD. Materials and Methods: This study prospectively enrolled individuals who underwent an upper gastrointestinal endoscopy during a health checkup. Each participant completed the reflux disease questionnaire (RDQ). Coffee or tea drinking was defined as drinking the beverage at least 4 days/week for 3 months. Heavy coffee or tea consumption was defined as drinking at least two cups every day. Results: A total of 1837 participants (970 men; age 51.57 ± 10.21 years), who had data on clinical characteristics and consumption of coffee and tea with or without additives such as milk or sugar were included for final analysis. Among them, 467 (25.4%) were diagnosed as having symptomatic GERD based on the RDQ score, and 427 (23.2%) had erosive esophagitis (EE) on endoscopy. Drinking coffee or tea was not associated with reflux symptoms or EE in univariate and multivariate analyses. In contrast, drinking coffee with milk was associated with reflux symptoms and drinking “tea and coffee” was associated with EE in univariate analysis. However, these associations became insignificant after multivariate analysis. Conclusion: Drinking coffee or tea and adding milk or sugar was not associated with reflux symptoms or EE.

Maryam Muhammad Aliyu, Idris Abdullahi Nasir, Yahaya Abdullahi Umar, Anthony Philip Vanstawa, Jessy Thomas Medugu, Anthony Uchenna Emeribe, Dele Ohinoyi Amadu
April-June 2017, 29(2):98-103
DOI:10.4103/tcmj.tcmj_22_17  PMID:28757774
Objective: Pregnant women infected with malaria represent a significant obstetric problem, especially in the face of antimalarial resistance. This cross-sectional study investigated the prevalence of malaria parasitemia, associated risk factors as well as the antimalarial resistance pattern of Plasmodium isolates from pregnant women attending four selected secondary health facilities in Kaduna State, Nigeria. Materials and Methods: Blood samples were collected from 353 pregnant women attending selected hospitals. Malaria microscopy and parasite density count were conducted based on standard protocols. Antimalarial susceptibility test (using chloroquine, artesunate, artether, and sulfadoxine-pyrimethamine), and hemoglobin concentrations were determined using schizont maturation assay and methemoglobin method, respectively. Multiple-drug resistance (MDR) was defined by resistance against ≥3 antimalarial drugs. Results: The overall prevalence of plasmodiasis was 22.4%. Out of those infected, 5.2% was found to be anemic. Malaria parasitemia was significantly associated with parity, residential area, age of women, and use of preventive measures against malaria (P < 0.05) but not with hemoglobin concentration, occupation, and trimester of pregnancy (P > 0.05). Malaria parasites from the pregnant women exhibited the highest resistance against chloroquine, 75 (94.9%) followed Artemether, 30 (37.9%) then sulfadoxine-pyrimethamine, 29 (36.7%) and least resistant to artesunate, 28 (35.4%). The prevalence of MDR was 40.5% (32/79). Conclusion: The prevalence of malaria was relatively high due to inadequate and/or ineffective preventive measures adopted by pregnant women. More so, significant isolates of Plasmodium falciparum exhibited MDR against antimalarial agents tested.

Treatment strategies for neuromyelitis optica
Tzu-Lun Huang, Kung-Hung Lin, Jia-Kang Wang, Rong-Kung Tsai
October-December 2018, 30(4):204-208
DOI:10.4103/tcmj.tcmj_102_18  PMID:30305782
Neuromyelitis optica (NMO) is an autoimmune demyelinating disease with pathogenic autoantibodies that act against the astrocyte water channel protein, i.e. aquaporin-4: the disease is associated with recurrent episodes of optic neuritis (ON) and transverse myelitis, often resulting in severe disability. The main goals in treatment of NMO include acute symptomatic therapy and long-term stabilization of symptoms by preventing relapse. In recent years, ongoing randomized controlled trials in NMO patients have studied evidence for treatment. Briefly, acute-stage management (with pulse therapy using corticosteroids and/or plasmapheresis) and maintenance therapy (including rituximab, mycophenolate mofetil, and azathioprine) have been recommended in some case series and retrospective studies. Because of the high prevalence of liver disease, all NMO patients in Taiwan should be screened for hepatitis B and C before treatment is initiated. Although immunosuppression and plasma exchange are the mainstays of therapy for NMO ON, several selective and potentially therapeutic strategies targeting specific steps in NMO pathogenesis including blockers of NMO-IgG binding and inhibitors of granulocyte function have been evaluated in recent years.

The association of hyperthyroidism and immune thrombocytopenia: Are we still missing something?
Kalyan Mansukhbhai Shekhda
July-September 2018, 30(3):188-190
DOI:10.4103/tcmj.tcmj_139_17  PMID:30069130
Though the American society of hematology Guidelines and British guidelines do not recommend screening of thyroid diseases in cases of immune thrombocytopenia (ITP), more than 160 cases of hyperthyroidism associated with ITP have been reported. Numerous case reports would suggest that patients with ITP and concurrent hyperthyroidism would respond to control of thyroid disease rather than the standard ITP treatment. Although this issue is still debatable, we report a case of a young female with a previous diagnosis of hyperthyroidism which was not well controlled, had presented with severe thrombocytopenia. Initially, all work-up had been done to find out the cause of thrombocytopenia. After all normal reports except deranged thyroid function tests, the patient was labeled as ITP and started on steroids. Even after a few months of steroid treatment, platelet counts had not improved. However, after starting antithyroid drugs, platelet counts had become normalized.

Evidence-based review and appraisal of the use of droperidol in the emergency department
Pei-Chun Lai, Yen-Ta Huang
January-March 2018, 30(1):1-4
DOI:10.4103/tcmj.tcmj_195_17  PMID:29643708
Droperidol is a short-acting, potent dopamine D2 antagonist that can pass through the blood–brain barrier. A black box warning was issued for droperidol by the United States Food and Drug Administration in 2001 because of a risk of development of torsades de pointes induced by QT prolongation. Many experts feel that the incidence of arrhythmia is overestimated, and low-dose droperidol is almost always used by anesthesiologists for postoperative nausea and vomiting. In this review, we used evidence-based analysis to appraise high-quality studies with a low risk of bias published after 2001 on the use of droperidol in the emergency department (ED). Droperidol appears not only efficacious but also safe to treat patients with nausea/vomiting, acute psychosis, and migraine in the ED. For these conditions, droperidol may be an option for shared decision-making.

Current consensus and controversy on the diagnosis of male lower urinary tract symptoms/benign prostatic hyperplasia
Cheng-Ling Lee, Hann-Chorng Kuo
January-March 2017, 29(1):6-11
DOI:10.4103/tcmj.tcmj_3_17  PMID:28757757
Traditionally, male lower urinary tract symptoms (LUTS) have been considered a synonym for benign prostate hyperplasia (BPH) because most male LUTS develops in aging men. Medical treatment should be the first-line treatment for BPH and surgical intervention should be performed when there are complications or LUTS refractory to medical treatment. Recent investigations have revealed that bladder dysfunction and bladder outlet dysfunction contribute equally to male LUTS. In the diagnosis of LUTS suggestive of BPH (LUTS/BPH), the following questions should be considered: Is there an obstruction? Are the LUTS caused by an enlarged prostate? What are the appropriate tools to diagnose an obstructive BPH? Should patients with LUTS be treated before bladder outlet obstruction is confirmed? This article discusses the current consensus and controversies in the diagnosis of LUTS/BPH.

Vegetarian diet, food substitution, and nonalcoholic fatty liver
Tina H Chiu, Ming-Nan Lin, Wen-Harn Pan, Yen-Ching Chen, Chin-Lon Lin
April-June 2018, 30(2):102-109
DOI:10.4103/tcmj.tcmj_109_17  PMID:29875591
Objectives: Vegetarian diets have been shown to improve insulin resistance and reduce body weight, but the effects on nonalcoholic fatty liver require further confirmation. We aim to investigate the association between vegetarian diets, major food groups, and nonalcoholic fatty liver, and to compare the degree of liver fibrosis between vegetarians and nonvegetarians in those with fatty liver. Materials and Methods: We analyzed cross-sectional data from the Tzu Chi Health Study which included 2127 nonvegetarians and 1273 vegetarians who did not smoke or habitually drink alcohol and had no hepatitis B or hepatitis C. Fatty liver and liver fibrosis were determined using ultrasonography and the nonalcoholic fatty liver disease fibrosis score, respectively. Diet was assessed through a validated food frequency questionnaire. Results: Vegetarian diets were associated with lower odds of fatty liver (odds ratio = 0.79, 95% confidence interval: 0.68–0.91) after adjusting for age, gender, education, history of smoking and alcohol drinking. Adjustment for body mass index (BMI) attenuated the protective association. Vegetarians had less severe fibrosis than nonvegetarians. Replacing a serving of soy with a serving of meat or fish was associated with 12%–13% increased risk, and replacing a serving of whole grains with a serving of refined grains, fruits, and fruit juice was associated with 3%–12% increased the risk of fatty liver. Conclusion: Vegetarian diets, replacing meat and fish with soy, and replacing refined carbohydrates with whole grains, may be inversely associated with nonalcoholic fatty liver related to BMI.

Salivary micro RNA as a potential biomarker in oral potentially malignant disorders: A systematic review
T N Uma Maheswari, Archana Venugopal, Nivedhita Malli Sureshbabu, Prathiba Ramani
April-June 2018, 30(2):55-60
DOI:10.4103/tcmj.tcmj_114_17  PMID:29875583
Oral potentially malignant disorders (OPMD) are oral mucosal disorders which have a high potential to turn into malignancy. A recent report suggests that 16%–62% of epithelial dysplasia cases of OPMD undergo malignant transformation, showing the need for early detection of malignancy in these disorders. Micro RNA (miRNA) plays an important role in cellular growth, differentiation, apoptosis, and immune response, and hence, deregulation of miRNA is considered a signature of oral carcinogenesis. A search was done using MeSH terms in the PubMed, ScienceDirect databases, hand search, and finally, six studies were included in this systematic review. A total of 167 patients with oral cancer, 78 with OPMDs, 147 healthy controls, and 20 disease controls were analyzed for the expression of salivary miRNAs. Quality assessment based on the Quality Assessment of Diagnostic Accuracy Studies 2 tool was used to obtain a risk of bias chart using Revman 5.3 software and it was proved that the study done by Zahran et al. in 2015 had a low risk of bias. The results of this study revealed upregulated miRNA 184 with an area under the curve (AUC) of 0.86 and miRNA 21 with an AUC of 0.73 and downregulated miRNA 145 with an AUC of 0.68, which proved that these miRNAs are significant in detecting early malignancy in OPMD and should be further analyzed in various populations. This systematic review explored the potential of expression of salivary miRNA in OPMD for future studies. This could pave the way to utilize saliva as a surrogate marker in diagnosing early malignant changes in OPMD.

Vegetarian diet and blood pressure in a hospital-base study
Hao-Wen Liu, Jia-Sin Liu, Ko-Lin Kuo
July-September 2018, 30(3):176-180
DOI:10.4103/tcmj.tcmj_91_17  PMID:30069127
Objective: Previous studies have reported that a vegetarian diet may lower blood pressure (BP), but the effect of diet on BP in asymptomatic participants with proteinuria is unknown. We examined the association of diet and BP in individuals with or without proteinuria. Materials and Methods: This cross-sectional study analyzed data from participants who were more than 40 years old and received physical checkups at Taipei Tzu Chi Hospital from September 5, 2005, to December 31, 2016. Diets were assessed at baseline by a self-reported questionnaire and categorized as vegan, lacto-ovo vegetarian, or omnivore. There were 2818 (7.7%) vegans, 5616 (15.3%) lacto-ovo vegetarians, and 28,183 (77.0%) omnivores. The effect of different parameters on BP was determined using a multivariate multiple linear regression model with no intercept, with control for important characteristics and lifestyle confounders. Results: The vegan group had a lower mean systolic BP (−3.87 mmHg, P < 0.001) and diastolic BP (−2.48 mmHg, P < 0.001) than the omnivore group. Participants with proteinuria had a higher systolic BP (4.26 mmHg, P < 0.001) and diastolic BP (2.15 mmHg, P < 0.001) than those without proteinuria. Interaction analysis indicated that vegan participants with proteinuria had a lower systolic BP (−2.73 mmHg, P = 0.046) and diastolic BP (−2.54 mmHg, P = 0.013) than other participants with proteinuria. However, individuals in the lacto-ovo group with proteinuria had a BP similar to other participants with proteinuria. Conclusions: A vegan diet was associated with lower BP in asymptomatic participants with proteinuria. This diet could be a nonpharmacologic method to reduce BP.

Acute myocardial ischemia/reperfusion (I/R) injury is a significant, unsolved clinical puzzle. In the disease context of acute myocardial infarction, reperfusion remains the only effective strategy to salvage ischemic myocardium, but it also causes additional damage. Myocardial I/R injury is composed of four types of damage, and these events attenuate the benefits of reperfusion therapy. Thus, inventing new strategies to conquer I/R injury is an unmet clinical need. A variety of pathological processes and mediators, including changes in the pH, generation of reactive oxygen radicals, and intracellular calcium overload, are proposed to be crucial in I/R-related cell injury. Among the intracellular events that occur during I/R, we stress the importance of protein phosphorylation signaling and elaborate its regulation. A variety of protein kinase pathways could be activated in I/R, including reperfusion injury salvage kinase and survivor-activating factor enhancement pathways, which are critical to cardiomyocyte survival. In addition to serine/threonine phosphorylation signaling, protein tyrosine phosphorylation is also critical in multiple cell functions and survival. However, the roles of protein kinases and phosphatases in I/R have not been extensively studied yet. By better understanding the mechanisms of I/R injury, we may have a better chance to develop new strategies for I/R injury and apply them in the clinical patient care.

Objective: The objective of this study was carried out to determine the knowledge about and preventive practices against neonatal tetanus (NNT) in young women of reproductive age. Materials and Methods: Descriptive cross-sectional study design of 380 randomly selected consenting young women of child-bearing age at a Nigerian tertiary educational institution. They completed a semi-structured questionnaire on knowledge about and risk factors for NNT, willingness to receive the vaccine, and uptake of tetanus toxoid vaccine. Results: The mean age (standard deviation) of the women was 22.4 (4.6) years ranging from 15 to 30 years. The majority (64.5%) had poor knowledge of the causes of and risk factors for NNT with only 31% knowing that immunizing women against tetanus prevents NNT. Most of the women (58%) were unwilling to receive tetanus immunization. A total of 15.5% had received tetanus toxoid, but only 0.5% had completed the required dosage. A higher proportion of respondents with good knowledge about tetanus had tetanus toxoid immunization (28.1% vs. 8.6%; P < 0.0001). Conclusion: Knowledge about NNT, willingness to receive the vaccine, and uptake of tetanus toxoid were unacceptably poor among respondents. There is a need for continuous education targeting young women on the link between the tetanus immunization status of women and the occurrence of NNT.

Increased prevalence of obstructive sleep apnea in patients with pectus excavatum: A pilot study
Yeung-Leung Cheng, I-Shiang Tzeng, Mei-Chen Yang
October-December 2018, 30(4):233-237
DOI:10.4103/tcmj.tcmj_115_17  PMID:30305787
Objective: Laryngomalacia is the most common congenital laryngeal anomaly and is associated with pectus excavatum (PE). Patients with laryngomalacia and patients with obstructive sleep apnea (OSA) both experience upper airway obstruction, and patients with laryngomalacia had been found to have a higher prevalence of PE. However, no studies have established the prevalence of OSA in patients with PE. We conducted this pilot study to evaluate the prevalence of OSA in patients with PE. Materials and Methods: A total of 42 patients ≥20 years old with PE who were admitted for Nuss surgery to correct PE in Taipei Tzu Chi Hospital between October 2015 and September 2016 were invited to participate in the study; 31 of the 42 patients agreed. All 31 patients completed an Epworth sleepiness scale questionnaire to evaluate excessive daytime sleepiness (EDS) and underwent overnight polysomnography to evaluate OSA before Nuss surgery. Results: The prevalence of snoring in the study participants was 100%. Ten of 31 patients (32.3%) reported EDS. The overall prevalence of OSA with an apnea/hypopnea index ≥5/h was 25.8%, and all patients with OSA were men. Conclusions: The prevalence of OSA in patients with PE seemed to be higher than that previously reported in the general population, implying that OSA might be a potential etiology or, at least, an aggravating factor for the development or progression of PE or might be responsible for the postoperative recurrence of PE in some patients. Further studies are needed to clarify this relationship.

Isolated sphenoid sinusitis is a rare disorder and may present with severe complications due to its proximity to the orbital and intracranial areas. We report a 13-year-old boy hospitalized for septic shock with fever of unknown origin. Facial palsy was later noted. Brain magnetic resonance imaging showed a sphenoid mass and right cavernous sinus and internal jugular vein thrombosis. Biopsy revealed chronic rhinosinusitis. Complete recovery followed by an incision/drainage procedure and antibiotic treatment. Acute sphenoid sinusitis should be included in the differential diagnosis of septic manifestations mimicking central nervous system infection or cranial nerve palsy.
