Frequency of functional esophageal disorders in patients with refractory reflux symptoms in Lima, Peru.

Gastroesophageal reflux disease (GERD) is a clinical condition in which gastric reflux causes symptoms or damage to the esophageal mucosa. It is managed with proton pump inhibitors, however, up to 45% of patients with suspected GERD are refractory to treatment. It is necessary to establish a true GERD diagnosis by means of a digestive endoscopy, which does not show lesions in approximately 70% of patients. In this scenario, it is necessary to perform an esophageal pH-impedance measurement, a procedure that allows to determine whether exposure to gastric acid is pathological. Of this group, patients with pathological acid exposure are diagnosed as true non-erosive reflux disease (NERD). If, in addition to not presenting esophageal lesions, they have a physiological exposure to gastric acid, they suffer from esophageal hypersensitivity or functional heartburn, which are functional disorders. These require a different approach from that of GERD or NERD, as the symptoms are not due to pathological exposure to gastric acid. The aim was to calculate the frequency of esophageal hypersensitivity and functional heartburn in patients with suspected NERD. This was a cross-sectional study. Data was collected by reviewing pH-impedance and manometry reports, 166 patients were selected. The frequency for functional disorders was 86.15%, being 46.9% for functional heartburn and 39.2% for esophageal hypersensitivity. The frequency of functional disorders was higher than that reported in previous studies. In conclusion, age, psychological conditions, dietary, cultural, ethnic or lifestyle factors inherent to our environment might play important roles in the development of functional disorders.

La enfermedad por reflujo gastroesofágico (ERGE) es una condición clínica en la que el reflujo gástrico provoca síntomas o daños en la mucosa esofágica. Se maneja con inhibidores de la bomba de protones; sin embargo, hasta el 45% de los pacientes con sospecha de ERGE son refractarios al tratamiento. Por lo cual, es necesario establecer un verdadero diagnóstico de ERGE mediante una endoscopia digestiva, que no muestra lesiones en aproximadamente el 70% de los pacientes. En este escenario, es necesario realizar una medición de pH-impedancia esofágica, procedimiento que permite determinar si la exposición al ácido gástrico es patológica. De este grupo, los pacientes con exposición patológica al ácido son diagnosticados como verdadera enfermedad por reflujo no erosiva (ERNE). Si además de no presentar lesiones esofágicas, tienen una exposición fisiológica al ácido gástrico, padecen hipersensibilidad esofágica o pirosis funcional, que son trastornos funcionales. Estos requieren un enfoque diferente al ERGE o ERNE, ya que los síntomas no se deben a una exposición patológica al ácido gástrico. El objetivo fue calcular la frecuencia de hipersensibilidad esofágica y pirosis funcional en pacientes con sospecha de ERNE. Este fue un estudio transversal. Los datos se recopilaron mediante la revisión de informes de pH-impedancia y manometría, se seleccionaron 166 pacientes. La frecuencia de trastornos funcionales fue de 86,15%, siendo 46,9% de pirosis funcional y 39,2% de hipersensibilidad esofágica. La frecuencia de trastornos funcionales fue superior a la reportada en estudios previos. En conclusión, la edad, las condiciones psicológicas, los factores dietéticos, culturales, étnicos o de estilo de vida inherentes a nuestro entorno podrían jugar un papel importante en el desarrollo de trastornos funcionales.

Factors associated with normal or abnormal Papanicolaou smear among HIV-infected women at a national hospital in Lima, Peru, 2012-2015.

HIV-infected women are at a risk of developing abnormal lesions of the uterine cervix. The objective of this study was to determine factors associated with normal or abnormal Papanicolaou (Pap) smear among HIV-infected women. A case-control study was conducted; case and control were defined as HIV-infected women ≥18 years with an abnormal and normal Pap smear, respectively. A logistic regression analysis was performed, and the Odds Ratio (OR) was calculated with its 95% Confidence Interval (CI). We included 368 patients, and the mean age was 36.83 years (SD ± 9.81), similar between cases and controls. Regarding cases, 30.50% (n = 43) had an alcohol consumption (AC), 75.18% (n = 106) were on antiretroviral therapy (ART) and 37.74% (n = 40) were in virologic failure (VF). About controls, 18.02% (n = 41) had AC, 85.02% (n = 193) were on ART, and 23.12% (n = 40) were in VF. In multivariate analysis, AC [OR: 1.77 (1.06-2.95)], VF [OR: 2.41 (1.55-3.74)], and ART [OR: 0.07 (0.02-0.23)] were significant factors. The risk factors associated with an abnormal Pap smear were AC and VF. ART was a protective factor. Therefore, besides scheduled Pap smear, human papillomavirus screening/immunization, VF, and ART should be strictly reinforced, and AC should be mitigated.

Epidemiology and associated factors of irritable bowel syndrome in an Andean community from Peru.

INTRODUCTION: Irritable bowel syndrome (IBS) is a chronic functional bowel condition with an average world prevalence of 11.2%. Is associated with multiple factors as female sex, young age, stress, anxiety and depression which can have a negative impact on quality of life. IBS in Peru is not investigated at all specially in the Andean region. The objective of this study is to determine the prevalence and associated factors of IBS in an Andean community from Peru using the Rome IV criteria. MATERIALS AND METHODS: Cross-sectional study in a rural community dedicated to livestock and agriculture in Peru at 3,235 meters above sea level. Questionnaires provided by the Rome Foundation as the Rome IV - Diagnostic questionnaire for adults, Irritable Bowel Syndrome - Symptom Severity Scale and Bristol stool scale were used. RESULTS: 130 residents met the inclusion criteria. 46.9% were males with an average age of 54 years old. 11.54% presented red flags and were not included in the analysis. 13.1% were diagnosed with IBS and 52.9% presented constipation as predominant bowel pattern. 52.9% presented a mild course of the disease. In the chi-square analysis, factors as depression, anxiety, female sex, younger age, liquefied petroleum gas exposure for cooking and education achievement were statistically significant associated to IBS. In the logistic regression analysis, anxiety was the unique independent predictor factor with an OR of 9.6 (95% IC: 1.78-51.82). CONCLUSION: IBS is a prevalent condition in the Andean region and should be managed as a public health issue to improve quality of life.

ABSTRACT Objective : to explore whether there is an association between the frequency of insulin resistance and the presence and distribution of acanthosis nigricans in obese children. Materials and methods : this is a cross-sectional study in which 42 obese children between 5 and 10 years of age participated. The presence of acanthosis nigricans was characterized (number and distribution of affected areas) as well as other variables, such as age, sex, and Body Mass Index. Four groups were formed, and the frequency of insulin resistance was determined, aiming to explore its association with the other variables. Results : mean participants' age was 8.6 years, and male subjects accounted for 54.8%. Nearly two-thirds of participants (64.3%) had acanthosis nigricans, and 78% of them had insulin resistance. Associated variables with statistical significance were age (p= 0.009), BMI (p= 0.025), and the presence of acanthosis nigricans affecting the neck region. Conclusions : there is an association between insulin resistance and the presence of acanthosis nigricans affecting the neck of obese children.

Frequency and associated factors of amnestic mild cognitive impairment at four senior citizen clubs in Lima, Peru.

Amnestic mild cognitive impairment (aMCI) is a subtle alteration in cognitive function that does not affect day-to-day activities and can precede Alzheimer's dementia. An increase in the prevalence of both these conditions is expected given the growing elderly population and recognizing risk factors can help reduce the burden. OBJECTIVE: the aim of this study was to determine the frequency and associated factors of aMCI in senior citizen clubs (SCC) at four districts with different socioeconomic status in Lima, Peru. METHODS: we applied Petersen's criteria to determine the presence of the condition in an interview which included the use of the Memory Alteration Test (M@T) and the Pfeffer Functional Activity Questionnaire (PFAQ). RESULTS: sixty-three out of 352 (17.9%) participants had aMCI. Factors associated with this condition were older age, fewer years of education at marriage whereas being from the SCC La Molina (district with highest socioeconomic status and resources for activities for the elderly) were associated with not having aMCI. There was no difference for sex, body mass index or history of hypertension. CONCLUSION: this predementia stage is frequent and usually undetected in urban Lima. Tools such as the M@T could help general practitioners detect this condition before its progression to dementia.

O comprometimento cognitivo leve amnésico (aMCI) é uma alteração sutil na função cognitiva que não altera as atividades do dia-a-dia e pode preceder a demência de Alzheimer. Um aumento na prevalência de ambas as condições é esperado devido ao crescimento da população idosa e o reconhecimento de fatores de risco pode ajudar a reduzir a carga de doença. OBJETIVO: o objetivo deste estudo foi o de determinar a freqüência e fatores associados a MCI em clubes de cidadãos idosos (CCI) em quatro distritos com diferentes condições socioeconômicas em Lima, Peru. MÉTODOS: aplicamos os critérios de Petersen para determinar a presença da condição em uma entrevista que incluiu o uso do Teste de Alteração de Memória (M@T) e do Questionário de Atividades Funcionais de Pfeffer (QAFP). RESULTADOS: sessenta e três dos 352 (17,9%) participantes tinham MCI. Os fatores associados a essa condição foram idade avançada, menor tempo de estudo ao se casar enquanto ser provenientes do CCI La Molina (distrito com maior nível socioeconômico e recursos para atividades para idosos) foram associados a não possuir um MCI. Não houve diferença por sexo, índice de massa corporal e história de hipertensão. CONCLUSÃO: este estágio de pré-demência é frequente e geralmente não detectado na cidade de Lima. Ferramentas como o M@T poderiam ajudar os clínicos gerais a detectar essa condição antes da progressão para a demência.

Comparación de la morbimortalidad de meningoencefalitis tuberculosa en pacientes inmunocompetentes e inmunocomprometidos de un hospital general / Comparison of morbimortality of tuberculous meningoencephalitis among immunocompromised and immunocompetent patients in a general hospital

Objetivos: Determinar la morbimortalidad de la meningoencefalitis tuberculosa en pacientes inmunosuprimidos e inmunocompetentes, atendidos en un hospital general. Material y métodos: Estudio descriptivo observacional. Se revisaron 77 historias clínicas de pacientes con diagnóstico de meningoencefalitis tuberculosa entre 2005 y 2014. Se evaluaron variables epidemiológicas, características clínicas y de laboratorio. Para medir la morbimortalidad nos basamos en el cuadro neurológico del paciente al ingreso y al alta. Fueron un total de 49 pacientes inmunocompetentes y 28 pacientes inmunosuprimidos. Resultados: La población más afectada fueron los varones y la media de la edad fue 39,7 ± 18,4 años. Los síntomas más comunes al ingreso fueron anorexia en el 82%, dolor de cabeza en el 77% y el aumento de la frecuencia respiratoria en 66%. Dentro de los síntomas neurológicos al ingreso, el 57% de los pacientes se encontraron en estadio 2, de ellos 29 (66%) pacientes eran inmunocompetentes. Al momento del alta, 75% se encontraron en la categoría 1; y de la categoría 4, 28% de las muertes correspondieron al grupo inmunosuprimidos y 72% al grupo inmunocompetentes, pero la diferencia no fue estadísticamente significativa. Se encontró diferencia estadísticamente significativa en cefalea (p=0,01), fiebre (p=0,001), nauseas (p=0,038) y frecuencia respiratoria elevada (p=0,0005), que fue más frecuente en inmunosuprimidos. Conclusiones: Parece observarse que la morbimortalidad es mayor en pacientes inmunocompetentes a comparación de los inmunosuprimidos. (AU)

Objectives: To compare morbimortality of tuberculous meningoencephalits among immunocompromised and immunocompetent patients in a general hospital. Methods: An observational study was performed reviewing 77 clinical charts of patients diagnosed of tuberculous meningoencephalits between 2005 and 2014. Epidemiological, clinical and laboratory data were gathered. Morbimortality was assessed comparing the neurologic examination on admission and at discharge. A total of 49 immunocompetent and 28 immunosuppressed were evaluated. Results: Males were more affected; mean age was 39.7 ± 18 years. The commonest symptoms on admission were anorexia (82%), headache (77%) and polypnea (66%); 57% were on stage 2, 29 of them (66%) were immunocompetent. At discharge, 75% were on stage1; among patients in grade 4, 28% of deaths occurred in immunosuppressed vs. 72% in immunocompetent, difference that did not reach statistical significance. Headache (p=0.01), fever (p=0.001), nausea (p=0.038) and polypnea (p=0.0005) were more frequent in immunosuppressed patients. Conclusions: This study shows that morbimortality is more common in immunocompetent hosts compared to immunosuppressed hosts. (AU)

[Behaviors in response to the tuberculin skin test conversion in medical students from a university in Lima, Peru]. / Conductas frente al viraje de la prueba de tuberculina en estudiantes de medicina de una universidad de Lima, Perú.

The aim of this study was to determine the behaviors in response to tuberculin skin test (PPD) conversion and the reasons for starting or not starting treatment for latent tuberculosis infection (TILT) among medical students at a university in Lima, Peru. A total of 548 participants completed a questionnaire; of them, 6.7% tested positive on university admission and 11.1% were recent converters. A total of 55.7% did not start TILT and had no explanation. Of the recent converters, most students who did start TILT were >22 years old (p = 0.01) and correctly answered general knowledge questions (p = 0.04). It is important to note that the PPD conversion rate was higher than that reported in the literature and that most students did not follow the treatment prophylaxis because of a lack of information.

RESUMEN El objetivo del estudio fue determinar las conductas frente al viraje de la prueba de tuberculina (PPD) y las razones del inicio o no del tratamiento de la infección latente tuberculosa (TILT) en estudiantes de Medicina en una Universidad de Lima, Perú; 548 participantes llenaron un cuestionario; se obtuvo que 6,7% fueron positivos al ingreso a la universidad y 11,1% fueron conversores recientes; de este grupo 55,7 % no iniciaron TILT y la principal razón fue "no hubo explicación". De los conversores recientes, la mayoría de alumnos que sí iniciaron el TILT, eran mayores de 22 años (p=0,01) y respondieron correctamente las preguntas sobre conocimientos generales (p=0,04). Es resaltante que la tasa de conversión de PPD fue más alta a la reportada en la literatura y que la mayoría de estudiantes no siguió la profilaxis por falta de información.

[Demographic and clinical aspects of hepatic fascioliasis between 2013-2010 in National Hospital Cayetano Heredia, Lima, Peru]. / Caracterización clínica y epidemiológica de la infección por fasciola hepática entre los años 2003-2010 en el Hospital Nacional Cayetano Heredia, Lima, Perú.

OBJECTIVE: To describe the demographic and clinical aspects of hepatic fascioliasis as well as the complications and associations between various factors and the disease in a reference hospital. METHODS: This is a descriptive and retrospective case series study; we included all patients who had a recent diagnosis of hepatic fascioliasis from 2003 to 2010 in the Hospital Nacional Cayetano Heredia. Demographic and clinical variables were analyzed including complications and treatment received. RESULTS: 68 medical records were found eligible for the study. The mean age was 36 years. Ancash department was the most frequent place of origin and residence. Most of them were diagnosed in the chronic phase, the most common symptom was abdominal pain and eight patients had complications: 3 hepatic abscess, 1 subcapsular hematoma, 1 cholangitis and 1 cholangitis plus cholecystitis. There were the following associations: Age under 15 years with chronic phase and hyporexia, being a student with a positive stool analysis; and between being born in an endemic area with the absence of complications. CONCLUSIONS: Hepatic fascioliasis has unspecific clinical presentation so the epidemiological or dietary history and specially eosinophilia should guide the diagnosis.

Most of them were diagnosed in the chronic phase, the most common symptom was abdominal pain and eight patients had complications: 3 hepatic abscess, 1 subcapsular hematoma, 1 cholangitis and 1 cholangitis plus cholecystitis. There were the following associations: Age under 15 years with chronic phase and hyporexia, being a student with a positive stool analysis; and between being born in an endemic area with the absence of complications. Conclusions: Hepatic fascioliasis has unspecific clinical presentation so the epidemiological or dietary history and specially eosinophilia should guide the diagnosis...

Propuesta de esquemas de tratamiento antituberculosis basados en la susceptibilidad a isoniacida y rifampicina / Proposal of anti-tuberculosis regimens based on susceptibility to isoniazid and rifampicin

Objetivo. Elaborar esquemas de tratamiento para tuberculosis de acuerdo con sus perfiles de susceptibilidad a isoniacida (H) y rifampicina (R). Materiales y métodos. Un total de 12 311 aislamientos de M. tuberculosis (Instituto Nacional de Salud, 2007-2009) se clasificaron en cuatro grupos de acuerdo con su susceptibilidad a H y R. En cada grupo se analizó la sensibilidad a etambutol (E), pirazinamida (Z), estreptomicina (S), kanamicina (Km), capreomicina (Cm), ciprofloxacina (Cfx), etionamida (Eto), cicloserina (Cs) y ácido p-amino salicílico (PAS). En base a los perfiles de resistencia, principios de terapéutica de la Organización Mundial de la Salud y costos en el país, se elaboraron los esquemas más adecuados para cada grupo. Se definió la eficacia potencial (EP) como la proporción de cepas sensibles a tres o cuatro drogas del esquema evaluado. Resultados. Los esquemas con el menor costo y la mayor EP a tres y cuatro drogas para tuberculosis sensible a H y R fueron: HRZ (EP=99,5%), HREZ (EP=99,1%); REZCfx (EP=98,9%) y para tuberculosis resistente a H: REZCfxKm (EP=97,7%). Para tuberculosis resistente a R: HEZCfx (EP=96,8%) y HEZCfxKm (EP=95,4%); el esquema con mejor eficacia potencial para tuberculosis multidrogorresistente fue EZCfxKmEtoCs (EP=82,9%). Conclusión. Basados en la resistencia a H y R se han elaborado y seleccionado esquemas de tratamiento con la más alta probabilidad de eficacia. Esta propuesta es una alternativa viable para hacer frente a la tuberculosis en Perú donde el acceso a pruebas de sensibilidad rápida a H y R se viene expandiendo. (AU)

Objective: To elaborate optimal anti-tuberculosis regimens following drug susceptibility testing (DST) to isoniazid (H) and rifampicin (R). Design: 12 311 M. tuberculosis strains (National Health Institute of Peru 2007-2009) were classified in four groups according H and R resistance. In each group the sensitivity to ethambutol (E), pirazinamide (Z), streptomycin (S), kanamycin (Km), capreomycin (Cm), ciprofloxacin (Cfx), ethionamide (Eto), cicloserine (Cs) and p-amino salicilic acid (PAS) was determined. Based on resistance profiles, domestic costs, and following WHO guidelines, we elaborated and selected optimal putative regimens for each group. The potential efficacy (PE) variable was defined as the proportion of strains sensitive to at least three or four drugs for each regimen evaluated. Results: Selected regimes with the lowest cost, and highest PE of containing 3 and 4 effective drugs for TB sensitive to H and R were: HRZ (99,5%) and HREZ (99,1%), respectively; RZECfx (PE=98,9%) and RZECfxKm (PE=97,7%) for TB resistant to H; HZECfx (96,8%) and HZECfxKm (95,4%) for TB resistant to R; and EZCfxKmEtoCs (82.9%) for MDR-TB. Conclusion: Based on resistance to H and R it was possible to select anti-tuberculosis regimens with high probability of success. This proposal is a feasible alternative to tackle tuberculosis in Peru where the access to rapid DST to H and R is improving progressively. (AU)

[Hemoconcentration, Apache II and Ranson as early predictors of severity in patients with acute pancreatitis in a hospital in Lima - Peru]. / Hemoconcentración, Apache II y Ranson como predictores tempranos de severidad en pacientes con diagnóstico de pancreatitis aguda en un Hospital de Lima - Perú

OBJECTIVE: Compare hemoconcetration, APACHE II and Ranson scores as early predictors of severity defined by Atlanta criteria in patients with acute pancreatitis at Hospital Nacional Cayetano Heredia. MATERIALS AND METHODS: Retrospective descriptive study between December 2009 to November 2010 done using a data collection sheet to gather study relevant information. We classified acute pancreatitis into mild or severe according to Atlanta symposium criteria for organ failure and/or local complications. Comparison of hematocrit values was made using a t Student test to detect a significant difference and the area below the ROC curve was analyzed. RESULTS: Counting with 151 patients, 103 women (68.2%), with mean age of 45.5 ± 19.17 years, 112 mild pancreatitis (74.2%) and 39 severe (25.8%). Mean hematocrit in mild cases was 38.40 ± 4.77% and 39.78 ± 7.35% in severe group with p equal to 0.182. Area below the ROC curve of 0.89 y 0.68 for APACHE II and Ranson scores respectively. CONCLUSION: Hemoconcentration and Ranson proved not to be as useful as APACHE II score in predicting severity in acute pancreatitis.

Sífilis en la gestación / Syphilis in pregnancy

La sífilis es una enfermedad de transmisión sexual, producida por Treponema pallidum, que compromete múltiples sistemas. Puede ser adquirida o congénita y presentarse en diferentes estadios de evolución. Esta enfermedad tiene impacto en la salud de la mujer gestante y el feto, por lo cual debe realizarse el tamizaje universal. Las manifestaciones clínicas son proteiformes, dependiendo del estadio clínico, y el diagnóstico se realiza por medio de pruebas no treponémicas y treponémicas. El estándar de oro del tratamiento es la penicilina; en pacientes alérgicas debe realizarse la prueba de desensibilización, debido a que los fármacos alternativos no han demostrado beneficio en la mujer gestante. El seguimiento se realiza con pruebas no treponémicas y se espera caída de los títulos, en cuatro veces su valor inicial a los seis meses y negativización a los 12 a 24 meses.

Syphilis is a sexual transmitted disease caused by Treponema pallidum that compromises multiple systems. It may be acquired or congenital and present in different stages of evolution. The disease has a profound impact on pregnant women and their fetuses’ health, reason for doing universal screening. Clinical manifestations are proteiform depending on the clinical stage; diagnosis is done by non treponemic and treponemic tests. Penicillin is the gold standard in treatment, and desensitizing tests should be performed in allergic patients because alternative drugs have not demonstrated benefit in pregnant women. Follow up is with non treponemic tests and one should expect levels fall four times of its initial value at six months and becoming negative at 12 to 24 months.

Evaluación de la consejería pretest para el VIH en un hospital nacional en Lima-Perú / Evaluating HIV pre-test counseling in people attending a national hospital in Lima, Peru

Objetivo Evaluar los conocimientos adquiridos por la consejería pretest para el VIH, en personas que acudieron a un hospital nacional de Lima, Perú. Método Estudio observacional descriptivo de corte transversal, que se realizó en 499 personas que acudieron a la Estrategia Sanitaria Nacional de Prevención y Control de ITS/VIH y SIDA, que fueron seleccionadas de manera probabilística de tipo intencional. Se aplicó una entrevista estructurada que utilizó un cuestionario validado por expertos con preguntas directas. Se definió como variable de conocimiento correcto a un puntaje ≥75 por ciento de respuestas correctas y como variable de conocimiento incorrecto a un puntaje <75 por ciento de respuestas incorrectas. Resultados El 64,1 por ciento (n = 320) de los encuestados fueron mujeres. El grupo de edad con mayor numero de respuestas correctas (40,3 por ciento, n=201) fue el de 22 a 28 años, (p<0,05). Las personas que acudieron por pareja con diagnóstico reciente de VIH/ SIDA, tuvieron mayor cantidad de respuestas correctas (12,3 en promedio). Los hombres alcanzaron un mayor nivel de conocimientos correctos (63,6 por ciento) en comparación con las mujeres (36,4 por ciento), (p<0,05). Solo 4,4 por ciento (n=22) del total, alcanzaron un nivel de conocimiento correcto. Conclusión El nivel de conocimiento adquirido con la consejería pretest en este hospital fue deficiente, no cumpliendo los objetivos de la misma. Se sugiere cambiar la metodología para que pueda aumentar la retención de información por las personas, y de esta manera reducir la morbi-mortalidad en ITS y VIH/ SIDA.

Objective Evaluating the knowledge acquired by the pre-test counselling programme in a national hospital in Lima Peru. Method A cross-sectional descriptive observational study was carried out on 499 patients attending the National STI/HIV Prevention and Control Sanitary Strategy service after they had been counselled. The patients were intentionally selected by probabilistic means. A questionnaire having direct questions was applied; it had been previously validated by experts. ≥75 percent of correct answers was defined as being a variable of correct knowledge and <75 percent of correct answers as incorrect knowledge. Results 64.1 percent (n=320) of the patients were female. The age group having a better level of knowledge after counselling was the 22-28 year old group, 40.3 percent (n=201) (p<0.05). People having a partner diagnosed as having HIV/AIDS answered more questions correctly (12.3 on average). Men showed higher correct knowledge (63.6 percent) related to women (36.4 percent) (p<0.05). Only 4.4 percent (n=22) of the patients had a correct level of knowledge. Conclusion The pre-test counselling programme did not improve knowledge regarding HIV/AIDS. It is thus suggested that the approach and method should be changed so that patients become well-informed, thereby reducing STI and HIV/AIDS-related morbidity and mortality.
