Barriers and Facilitators to HIV Treatment Adherence in Indonesia: Perspectives of People Living with HIV and HIV Service Providers.

HIV treatment adherence in Indonesia is a major challenge. Although previous studies have demonstrated several barriers and facilitators to adherence, studies providing a comprehensive analysis from both PLHIV and HIV service providers' perspectives are limited, especially in Indonesia. In this qualitative study with 30 people living with HIV on treatment (PLHIV-OT) and 20 HIV service providers (HSPs), we explored, via online interviews, the barriers and facilitators to antiretroviral therapy (ART) adherence using a socioecological approach. Both PLHIV-OT and HSPs reported stigma as a major barrier at each socioecological level, including public stigma at the societal level, stigma in healthcare settings, and self-stigma at the intrapersonal level. Stigma reduction must therefore be prioritized. PLHIV-OT and HSPs also reported support from significant others and HSPs as the foremost facilitators to ART adherence. The enablement of support networks is thus an important key to improved ART adherence. Overall, the societal level and health system barriers to ART adherence should be addressed in order to remove barriers and enhance the facilitators at the subordinate socioecological levels.

Groin Pain Syndrome Italian Consensus Conference on terminology, clinical evaluation and imaging assessment in groin pain in athlete.

The nomenclature and the lack of consensus of clinical evaluation and imaging assessment in groin pain generate significant confusion in this field. The Groin Pain Syndrome Italian Consensus Conference has been organised in order to prepare a consensus document regarding taxonomy, clinical evaluation and imaging assessment for groin pain. A 1-day Consensus Conference was organised on 5 February 2016, in Milan (Italy). 41 Italian experts with different backgrounds participated in the discussion. A consensus document previously drafted was discussed, eventually modified, and finally approved by all members of the Consensus Conference. Unanimous consensus was reached concerning: (1) taxonomy (2) clinical evaluation and (3) imaging assessment. The synthesis of these 3 points is included in this paper. The Groin Pain Syndrome Italian Consensus Conference reached a consensus on three main points concerning the groin pain syndrome assessment, in an attempt to clarify this challenging medical problem.

Minilaparoscopic colorectal resections: technical note.

Laparoscopic colorectal resections have been shown to provide short-term advantages in terms of postoperative pain, general morbidity, recovery, and quality of life. To date, long-term results have been proved to be comparable to open surgery irrefutably only for colon cancer. Recently, new trends keep arising in the direction of minimal invasiveness to reduce surgical trauma after colorectal surgery in order to improve morbidity and cosmetic results. The few reports available in the literature on single-port technique show promising results. Natural orifices endoscopic techniques still have very limited application. We focused our efforts in standardising a minilaparoscopic technique (using 3 to 5 mm instruments) for colorectal resections since it can provide excellent cosmetic results without changing the laparoscopic approach significantly. Thus, there is no need for a new learning curve as minilaparoscopy maintains the principle of instrument triangulation. This determines an undoubted advantage in terms of feasibility and reproducibility of the procedure without increasing operative time. Some preliminary experiences confirm that minilaparoscopic colorectal surgery provides acceptable results, comparable to those reported for laparoscopic surgery with regard to operative time, morbidity, and hospital stay. Randomized controlled studies should be conducted to confirm these early encouraging results.

Cardiac involvement in inflammatory bowel disease: role of acylcarnitine esters.

OBJECTIVES: Cardiovascular complications have been frequently described in Inflammatory Bowel Disease (IBD). Both Crohn disease and Ulcerative Colitis are characterized by malabsorption of some micronutrients, such as carnitine, which is a very important element for myocardial metabolism, being demonstrated that its deficiency correlates with heart involvement in coeliac disease. Aims of this study are to evaluate cardiac function in IBD patients asymptomatic for cardiovascular diseases and to correlate the cardiac data with the profile of carnitine esters plasma levels. MATERIALS AND METHODS: The study was carried out on 20 IBD patients by comparison with 18 sex- and age-matched clinically healthy controls. Personal and familial history, physical examination, standard electrocardiogram and echocardiogram were performed in all subjects. Complete panel of nutritional status parameters and serum levels of free carnitine and its esters were evaluated both in IBD patients and control subjects. RESULTS: Isovaleryl-carnitine, Tiglyl-carnitine, Octenoylcarnitine and Decanoyl-carnitine, were found to be significantly lower in IBD patients. Significant correlations were found between some carnitine esters and echocardiographic parameters although total and free carnitine were meanly more elevated in IBD. No statistically significant differences in echocardiographic parameters were found between IBD patients and control subjects. CONCLUSIONS: Deficiency of some isoforms of carnitine, especially those esterified with short chain fatty acids, may play an important role in cardiac involvement in course of IBD and could lead, over time, to dilated cardiomiopathy.

Frailty and disability in the elderly: a diagnostic dilemma.

Decreased reserves in multiple organ systems identify frailty syndrome in the elderly. However, its clinical diagnostic approach may be hard, particularly in patients with chronic diseases. The purpose of the study was to delineate the role of disability in the frailty syndrome in a group of hospitalized elderly people. A total of 150 consecutive patients (62 males/88 females), aged between 64 and 97 years and 1-2 days before hospital discharge, were submitted to several geriatric scales designed to assess disability and/or morbidity. All the geriatric scales used showed an elevated percentage of abnormal values both in females and in males. Nevertheless, the activities of daily living (ADL), instrumental activities of daily living (IADL), Tinetti balance index (TBI), Barthel index (BI) scores showed significantly better values in men than in women (p=0.007, =0.02, =0.02 and =0.01, respectively). This preliminary cross-sectional study, underlines the fact that all geriatric tests employed have shown pathological scores, but those of the ADL, IADL, TBI and BI scores exploring disability were significantly better in males than in females. The mismatch between functional and morbidity tests seems to support the hypothesis that a disability state may be independent from morbidity.

Parathyroidectomy erase increased myocardial electrical vulnerability in patients with primary hyperparathyroidism.

BACKGROUND: Patients with primary hyperparathyroidism (pHPT) show an increased bioelectrical risk not related to cardiovascular complications, this risk seems to persist after surgery and this last finding is still controversial and probably related to follow-up length. METHODS: The aim of the study is to evaluate QT parameters in 11 patients with primary hyperparathyroidism (pHPT) 18 months after parathyroid surgery using computed standard 12-leads ECG compared to those of 29 healthy subjects (HS). RESULTS: In pHPT patients, 4 months after parathyroidectomy QT and QTc dispersion persist significantly higher than HS. 18 months after surgery, QT and QTc dispersion resulted comparable with HS. QT dispersion was found significantly higher in pHPT at 4 months respect 18 months after parathyroidectomy. CONCLUSIONS: ECG alteration after parathyroidectomy gradually return within normal limits and we can affirm that surgery erase bioelectrical risk in pHPT.

Transoral surgical removal of a giant fibrolipoma of the esophagus: case report.

An esophageal mass of more than 20 cm in length was diagnosed in a patient who presented with persistent dysphagia. Diagnosis of an endo-esophageal tumour was made by barium swallow; esophagoscopy confirmed the presence of a capsulated pink endo-esophageal mass. MRI confirmed the presence of a large capsulated mass within the esophagus, that appeared to be adipose tissue; a small stalk originating at the level of the upper esophageal sphincter was described and the polyp extended down to the gastroesophageal junction. Demonstration of the site and length of the stalk allowed a transoral removal of the mass, performed through a Weerda diverticuloscope (Karl Storz Endoskopie Gmbh, Tuttlingen Germany), a technique that has never been described before. Histology confirmed the mass as a fibrolipoma. The authors discuss both the role of MRI in diagnosis and treatment planning and the technique of transoral excision.

Persistent dysphagia after laparoscopic fundoplication for gastro-esophageal reflux disease.

Persistent postoperative dysphagia is a potentially severe complication of fundoplication for gastroesophageal reflux disease (GERD). The aim of this retrospective study was to analyze our experience of laparoscopic fundoplication for GERD in 276 consecutive patients, to determine the frequency of postoperative dysphagia and assess treatments and outcomes. There was no relation between preoperative dysphagia, present in 24 patients (8.7%), and postoperative DeMeester grade 2 or 3 dysphagia, present in 25 patients (9.1%). Ten (3.6%) patients had clinically significant postoperative dysphagia, eight (2.9%) underwent esophageal dilation, with symptom improvement in five. Four (1.4%) of our patients (two with failed dilation) and 11 patients receiving antireflux surgery elsewhere, underwent re-operation for persistent dysphagia 12 months (median) after the first operation. DeMeester grade 0 or 1 dysphagia was obtained in 10/13 evaluable patients. Our experience is fully consistent with that of the recent literature. Redo surgery is necessary in only a small fraction of operated patients with GERD with good probability of resolving the dysphagia. Best outcomes are obtained when an anatomical cause of the dysphagia is documented preoperatively.

Long-term sequelae after 1,311 primary inguinal hernia repairs.

BACKGROUND: Aim of this study was to analyze long-term sequelae, risk factors, and satisfaction after inguinal hernia primary repair. METHODS: A postal questionnaire was mailed to all patients operated between January 1997 and December 2004 for inguinal hernia repair. Patients who had a lump in the groin and patients who experienced chronic problems were invited for a physical examination. Patients who reported having chronic pain were asked to fill out the short-form McGill Pain Questionnaire (SF-MPQ). RESULTS: Chronic pain was present in 18.1% of cases. The strongest risk factors were presence of recurrence, use of heavyweight mesh, and age younger than 66 years. By means of the SF-MPQ, we found that the pain reported by most patients was sensory-discriminative in quality, with "tender" and "aching" being the most common descriptors used. About 71.3% of replies used descriptors typical of nociceptive pain, 8.9% of neuropathic pain, and 19.8% of nociceptive plus neuropathic. Chronic pain was severe in 2.1% of patients and interfered with normal activities, work, and exercise. The cumulative recurrence rate was 2.1%. There was a strong correlation between lump and recurrence. Patients declared themselves satisfied with the result of the operation in 93.1% of cases. Due to chronic pain, 6.5% of patients were unsatisfied. CONCLUSIONS: This study demonstrates that the main problem after inguinal hernia repair remains chronic pain, which was the primary reason of dissatisfaction. The SF-MPQ is feasible and easy to administer to all patients and provides important information about qualitative features of the pain.

A decision support system for the acquisition and elaboration of EEG signals: the AmI-GRID environment.

This paper describes a data-driven Decision Support System for Electroencephalography (EEG) signals acquisition, and parallel elaboration based on the integration of an Ambient Intelligent (AmI) [1] platform and a GRID enabled Infrastructure. The paper explores the analysis and design of the environment, the real-time data acquisition, the integration of the acquired data in dedicated EHR, and the EEG processing through parallel analysis algorithm available on the GRID infrastructure. After an overview of background concepts, the paper presents a brief description of the environment architecture, and a detailed analysis of the EEG algorithm. The challenge of the work presented is to effectively show how medical data can be shared and processed by exploiting the resources and capabilities of both the AmI platform and the GRID infrastructure. This particular Decision Support System, shows how it is possible to improve patient safety, quality of care, and efficiency in healthcare delivery.

Analysis of post-surgical pain after inguinal hernia repair: a prospective study of 1,440 operations.

BACKGROUND: Pain remains a significant clinical problem after inguinal hernia repair. We prospectively assessed post-surgical pain following herniorrhaphy in 1,440 operations with the aim of describing the characteristics and identifying predisposing factors for pain. METHODS: Pain quality was assessed with the short-form McGill Pain Questionnaire (SF-MPQ); pain character was estimated as either nociceptive or neuropathic in nature. RESULTS: A total of 38.3% of replies reported pain (acute or chronic), and 18.7% reported chronic pain. Independent risk factors for pain were young age, BMI >25, day surgery, and use of Radomesh. In patients with chronic pain, independent risk factors were young age, BMI >25 and use of Radomesh. Analysis of the SF-MPQ revealed that the pain reported by most patients was sensory-discriminative in quality. The most common descriptors were tender and aching. Patients with chronic pain reported more intense pain and used sensory descriptors of greater mean intensity than patients with acute pain. A total of 73.9% of replies used descriptors typical of nociceptive pain, 6.5% used descriptors typical of neuropathic pain and 19.6% used nociceptive plus neuropathic descriptors. Patients considered to have nociceptive pain used significantly more sensory descriptors than those considered to have neuropathic pain. By contrast patients with neuropathic pain used more affective descriptors than those with nociceptive pain. Neuropathic pain was reported as more difficult to treat with analgesics than nociceptive pain and neuropathic plus nociceptive pain. CONCLUSIONS: Our study confirms that herniorrhaphy frequently produces chronic pain, which can reduce quality of life. The SF-MPQ is a useful instrument to administer to all patients and provides important information about qualitative properties of the pain.

Bioprofiling over grid for eHealthcare.

A trend in modern medicine is towards individualization of healthcare and, potentially, grid computing can play an important role in this by allowing sharing of resources and expertise to improve the quality of care. In this paper, we present a new test bed, the BIOPATTERN Grid, which aims to fulfil this role in the long term. The main objectives in this paper are 1) to report the development of the BIOPATTERN Grid, for biopattern analysis and bioprofiling in support of individualization of healthcare. The BIOPATTERN Grid is designed to facilitate secure and seamless sharing of geographically distributed bioprofile databases and to support the analysis of bioprofiles to combat major diseases such as brain diseases and cancer within a major EU project, BIOPATTERN (www.biopattern.org); 2) to illustrate how the BIOPATTERN Grid could be used for biopattern analysis and bioprofiling for early detection of dementia and for brain injury assessment on an individual basis. We highlight important issues that would arise from the mobility of citizens in the EU, such as those associated with access to medical data, ethical and security; and 3) to describe two grid services which aim to integrate BIOPATTERN Grid with existing grid projects on crawling service and remote data acquisition which is necessary to underpin the use of the test bed for biopattern analysis and bioprofiling.

Diaphragmatic acute massive herniation after laparoscopic gastroplasty for esophagectomy.

Minimally invasive techniques are increasingly being used for oesophagectomy. Diaphragmatic hernia is a rare complication of gastroplasty in open surgery. One of the advantages of the laparoscopic technique, the lack of peritoneal adhesions, may lead to an increased rate of this complication. We report two cases of diaphragmatic acute massive herniation after laparoscopic gastroplasty for esophagectomy out of a series of 44 laparoscopic gastroplasties performed over 33 months. We discuss some technical aspects related to its occurrence. Prevention should include a limited crural division and fixation of the gastric tube to the diaphragmatic crura at primary surgery.

A lower level of entropy in circadian rhythm of the sinus R-R intervals suggests a prevalence of the cardiac sympathetic regulation in early physiological pregnancy.

The study estimates the unpredictable disorder (chaos) within the 24 h pattern of sinus R-R intervals (SRRI) in clinically healthy pregnant women (CHPW) and clinically healthy non-pregnant women (CHNPW), in order to evaluate the early gestational changes in neurovegetative cardiac pacing. SRRI were provided by the 24-h Holter ECG of 10 CHPW and 10 CHNPW. SRRI were investigated by descriptive conventional statistics by means of the Time and Frequency Domain Analysis, and subsequently, in their chaotic component by means of entropy analysis. Both the SRRI and entropy were tested via the Cosinor method to better decipher whether or not the periodic disorder in heart rate variability is modified in pregnancy as a result of a gestational tonic resetting of the cardiac sympatho-vagal regulation. Cosinor analysis documented that the circadian rhythm of both the SRRI and entropy were preserved in CHNPW and CHPW. However, the circadian rhythm of SRRI and entropy in CHPW exhibited a significantly decreased 24 h mean. Via the analysis of the rhythmicity of entropy, this study has documented that the chaos in the 24 h pattern of SRRI is less prominent in CHPW than in CHNPW. Such a reduction of level in the deterministic periodic chaos of heart rate variability provides evidence that, in early pregnancy, a tonic elevation of the sympathetic activity regulates cardiac pacing.

Carnitine deficiency in patients with coeliac disease and idiopathic dilated cardiomyopathy.

BACKGROUND AND AIMS: Idiopathic dilated cardiomyopathy (IDCM) and coeliac disease (CD) are two pathological conditions which may lead, by different mechanisms, to malabsorption of various micronutrients, including carnitine, active in cardiac metabolism. The aim of the present investigation was primarily to evaluate differences in serum concentrations of total carnitine between IDCM patients and patients with IDCM associated with CD and then also to evaluate, in the latter, the effect of a gluten-free diet on serum concentrations of total carnitine. METHOD AND RESULTS: Serum carnitine was determined by enzymatic spectrophotometric assay in three groups of individuals: group A, 10 patients (5 males, 5 females), mean age 46.5+/-10.8 years, presenting isolated IDCM; group B, 3 patients (2 males, 1 female), mean age 34+/-8 years, with IDCM+CD; and group C, 10 healthy subjects (5 males, 5 females), mean age 38.6+/-11.1 years. All patients with IDCM belonged to class NYHA I-II. Mean concentrations of total serum carnitine in the group of patients with isolated IDCM (group A) were found to be lower than in the controls (group C). The concentrations in patients with IDCM associated with CD (group B) were lower than in the control group and also lower than in the isolated IDCM (group A). After 2 years on a gluten-free diet, patients presenting IDCM associated with CD showed a progressive increase in mean serum carnitine levels compared to values observed prior to the diet. CONCLUSIONS: Patients presenting IDCM associated with CD show a greater decrease in serum total carnitine levels than patients presenting the isolated form of IDCM. A gluten-free diet, in these patients, leads to a progressive increase in serum levels of this substance.

Pre-operative endoscopic ultrasonography can optimise the management of patients undergoing laparoscopic cholecystectomy with abnormal liver function tests as the sole risk factor for choledocholithiasis: a prospective study.

BACKGROUND: Pre-operative endosonography has been proposed as a cost-effective procedure in the management of patients who undergo laparoscopic cholecystectomy having an intermediate risk of common bile duct stones. We prospectively evaluated the impact of pre-operative endosonography on the management of patients facing laparoscopic cholecystectomy with abnormal liver function tests as the sole risk factor for choledocolithiasis. METHODS: Among 587 consecutive patients scheduled for laparoscopic cholecystectomy, 47 (8%) patients having one or more abnormal liver function tests but a normal appearance of common bile duct at abdominal ultrasound, underwent pre-operative endosonography. In patients with endosonography-detected common bile duct stones, a pre-operative endoscopic retrograde cholangiography was performed, or an intra-operative endoscopic retrograde cholangiography was scheduled. In all endosonography-negative patients, an intra-operative trans-cystic cholangiography was performed. RESULTS: Endosonography detected common bile duct stones in nine patients (19%) but only in five of them stones were radiologically confirmed (PPV 0.55). Endosonography-detected stones were confirmed in four of four (100%) patients in whom cholangiography was performed within 1 week, but only in one of five (20%) patients in whom radiology was further delayed (P < 0.05). In three of four cases (75%), stones detected at endosonography but not confirmed at X-rays, were smaller than 2.0 mm. Among 38 patients with negative endosonography, common bile duct stones were found in two patients (NPV 0.95), whereas unplanned endoscopic stone extraction was needed only in one patient (NPV 0.97). CONCLUSIONS: Pre-operative endosonography can spare unnecessary pre-operative endoscopic retrograde cholangiography as well as inappropriate scheduling of intra-operative endoscopic retrograde cholangiography in patients undergoing laparoscopic cholecystectomy with abnormal liver function tests. To maximise the impact of endosonography on the management of these patients, the procedure should be performed immediately before laparoscopic cholecystectomy.

Bactericidal activity of Pistacia lentiscus mastic gum against Helicobacter pylori.

In this study we evaluated the antibacterial activity of mastic gum, a resin obtained from the Pistacia lentiscus tree, against clinical isolates of Helicobacter pylori. The minimal bactericidal concentrations (MBCs) were obtained by a microdilution assay. Mastic gum killed 50% of the strains tested at a concentration of 125 microg/ml and 90% at a concentration of 500 microg/ml. The influence of sub-MBCs of mastic gum on the morphologies of H. pylori was evaluated by transmission electron microscopy. The lentiscus resin induced blebbing, morphological abnormalities and cellular fragmentation in H. pylori cells.

Laparoscopic treatment of epiphrenic diverticula.

BACKGROUND AND PURPOSE: Epiphrenic diverticula are a rare disease probably caused by long-standing impairment of esophageal motor activity. Symptomatic disease, which may worsen clinically during follow-up even to severe symptoms, is usually considered an indication for surgical treatment. Surgery for epiphrenic diverticula consists of diverticulectomy, which traditionally is performed through a left thoracotomy; a myotomy and partial fundoplication are generally included in order to treat the underlying motor disorder and to prevent or correct reflux. The same principles of surgical treatment can be achieved through the laparoscopic transhiatal approach. The aim of this paper is to describe the technique and the results of laparoscopic diverticulectomy combined with esophageal myotomy and antireflux wrap to treat epiphrenic diverticula of the esophagus. PATIENTS AND METHODS: From January 1994 through May 2001, 11 patients underwent laparoscopic transhiatal diverticulectomy, esophageal myotomy, and partial fundoplication at our institution. RESULTS: In all patients, the operation was completed through the minimally invasive access. The postoperative course was complicated in one patient (9%), who had a leak from the staple line, which was repaired through a thoracotomy. At follow-up, this patient had persistence of a small pouch at the diverticuletomy site. However, he was asymptomatic. All other patients were free of symptoms and without recurrence. CONCLUSION: Laparoscopy offers good access to the distal esophagus and the inferior mediastinum. Removal of the diverticulum, treatment of the motor disorder, and prevention of postoperative reflux can all be obtained through this approach. The immediate postoperative and long-term results are satisfactory.

Evaluating results of laparoscopic surgery for esophageal achalasia.

BACKGROUND: Extramucosal myotomy of the lower esophagus and cardia, combined with anterior fundoplication, is, in our opinion, the procedure of choice to treat stage I-III esophageal achalasia. METHODS: After a successful experience with open surgery in over 280 patients, from January 1992 through February 1997, 61 patients underwent laparoscopic Heller-Dor for stage I-III achalasia. Conversion to laparotomy was done in three cases. All procedures were performed under intraoperative endoscopic control. Intraoperative complications were seven mucosal tears, which were sutured laparoscopically in five cases. The sole postoperative complication was bleeding from an acute gastric ulcer (conservative treatment). RESULTS: Follow-up consisted of clinical and radiographic study 1 month after surgery, and endoscopy and manometry within 1 year. After a mean follow-up (F.U.) of 21 months (1-62), clinical results range from excellent to good in 98.2%. One patient (1.7%) complaining of recurrent dysphagia improved after endoscopic dilation. Esophageal diameter reduced from 52 to 27 mm. LES pressure reduced from 30.3 +/- 12.4 to 10.7 +/- 3.5 mmHg (basal) and from 14. 8 +/- 9.3 to 2.9 +/- 2.1 mmHg (residual). CONCLUSIONS: Laparoscopic Heller-Dor operation is feasible, safe, and effective. Special care should be taken in patients with previous endoscopic dilations.

Diverticulectomy, myotomy, and fundoplication through laparoscopy: a new option to treat epiphrenic esophageal diverticula?

OBJECTIVE: To describe the technique and the results of laparoscopic diverticulectomy combined with esophageal myotomy and antireflux wrap for epiphrenic diverticula of the esophagus. SUMMARY BACKGROUND DATA: The epiphrenic diverticulum of the esophagus is a rare disease probably caused by a longstanding impairment of the esophageal motor activity. Although there is almost universal agreement to operate only on symptomatic patients, the optimal treatment is controversial. The best-accepted guideline is to treat the underlying motor disorder. This is generally done through a left thoracotomic approach that allows diverticulectomy, esophageal myotomy, and partial fundoplication. METHODS: From January 1994 through February 1996, 4 patients underwent laparoscopic transhiatal diverticulectomy, esophageal myotomy, and partial fundoplication at our institution. A thorough preoperative study was done with barium swallow, esophagoscopy, and manometry in all patients; 24-hour pH monitoring was done in one case. RESULTS: No postoperative complications were observed. Short- and medium-term results are satisfactory. CONCLUSIONS: No theoretical objection should be made to this approach, because the principle of treatment of the diverticular pouch and the underlying motor disorder and the prevention of reflux is respected. Longer follow-up and a wider series are mandatory to substantiate these initially favorable results.
