Objective:

Several countries have reported increasing incidence of oral cavity and oropharyngeal (OCOP) squamous cell carcinoma (SCC) over recent years, particularly among young men and primarily in tongue and tonsil subsites, attributed to human papillomavirus (HPV) infection. This study examines trends in incidence and age distribution of OCOP SCC in Jamaica over a 30-year period.

Methods:

We extracted all cases of OCOP SCC archived in the Jamaica Cancer Registry files over the 30 year-period from 1978 to 2007 and grouped them according to anatomical site (International Classification of Diseases; ICD-9), age and gender. The data were used to calculate age-standardized rates (ASRs) and age-specific incidence rates (ASIRs).

Results:

There were 384 patients (age range 21 to 94 years; male to female ratio 2.6:1) with OCOP SCC; the majority (85.4%) was > 50 years. Age-standardized rates of all OCOP SCC combined were higher in males than in females and there was a decrease in both genders over the study period. Tongue and tonsil were the commonest subsites, and males showed decreasing ASR in both. Females showed decreasing ASR in tongue and fluctuation in tonsil SCCs. The highest ASIRs for tongue and tonsil SCC were consistently seen in patients older than 50 years of age.

Conclusion:

The incidence of OCOP SCC is decreasing and continues to predominate among older men. The decreasing trend in incidence of tongue and tonsil SCC is unlike that reported elsewhere. This may be due to differences in sexual practices, small size of this study, or a lag time in emergence of a new trend.  相似文献

Background

Regulatory T cells (Treg) and dendritic cells (DC) play an important role in tumor immunity and immune escape. However, their interplay and the effects of anti-cancer therapy on the human immune system are largely unknown.

Methods

For DC generation, CD14+ monocytes were enriched by immunomagnetic selection from peripheral blood of advanced head and neck squamous cell carcinoma (HNSCC) patients and differentiated into immature DC using GM-SCF and IL-4. DC maturation was induced by addition of TNFα. The frequency of CD4+CD25highF0XP3+ Treg in HNSCC patients was analyzed before and after radio-chemotherapy (RCT) by four-color flow cytometry.

Results

In HNSCC patients, the frequency of Treg (0.33 ± 0.06%) was significantly (p = 0.001) increased compared to healthy controls (0.11 ± 0.02%), whereas RCT had variable effects on the Treg frequency inducing its increase in some patients and decrease in others. After six days in culture, monocytes of all patients had differentiated into immature DC. However, DC maturation indicated by CD83 up-regulation (70.7 ± 5.5%) was successful only in a subgroup of patients and correlated well with lower frequencies of peripheral blood Treg in those patients.

Conclusion

The frequency of regulatory T cells is elevated in HNSCC patients and may be modulated by RCT. Monocyte-derived DC in HNSCC patients show a maturation deficiency ex vivo. Those preliminary data may have an impact on multimodality clinical trials integrating cellular immune modulation in patients with advanced HNSCC.  相似文献

Objective

Little evidence exists on effective interventions to integrate HIV-care guidelines into practices within developing countries. This study tested the hypothesis that clinical summaries with computer-generated reminders could improve clinicians'' compliance with CD4 testing guidelines in the resource-limited setting of sub-Saharan Africa.

Design

A prospective comparative study of two randomly selected outpatient adult HIV clinics in western Kenya. Printed summaries with reminders for overdue CD4 tests were made available to clinicians in the intervention clinic but not in the control clinic.

Measurements

Changes in order rates for overdue CD4 tests were compared between and within the two clinics.

Results

The computerized reminder system identified 717 encounters (21%) with overdue CD4 tests. Analysis by study assignment (regardless of summaries being printed or not) revealed that with computer-generated reminders, CD4 order rates were significantly higher in the intervention clinic compared to the control clinic (53% vs 38%, OR=1.80, CI 1.34 to 2.42, p<0.0001). When comparison was restricted to encounters where summaries with reminders were printed, order rates in intervention clinic were even higher (63%). The intervention clinic increased CD4 ordering from 42% before reminders to 63% with reminders (50% increase, OR=2.32, CI 1.67 to 3.22, p<0.0001), compared to control clinic with only 8% increase from prestudy baseline (CI 0.83 to 1.46, p=0.51).

Limitations

Evaluation was conducted at two clinics in a single institution.

Conclusions

Clinical summaries with computer-generated reminders significantly improved clinician compliance with CD4 testing guidelines in the resource-limited setting of sub-Saharan Africa. This technology can have broad applicability to improve quality of HIV care in these settings.  相似文献

Background

Diabetes mellitus (DM) is now prevalent in many countries in sub-Saharan Africa, with associated health and socioeconomic consequences. Adherence to antidiabetic medications has been shown to improve glycaemic control, which subsequently improves both the short- and long-term prognosis of the disease. The main objective of this study was to assess the level of adherence to antidiabetic drugs among outpatients in a teaching hospital in southwestern Nigeria.

Methods

A cross-sectional study was carried out using the eight-item Morisky Medication Adherence Scale (MMAS-8) among diabetic patients attending the medical outpatients'' diabetes clinic of Ladoke Akintola University Teaching Hospital, in Ogbomosho, Oyo State in southwestern Nigeria, during a three-month period (October to December 2013).

Results

A total of 129 patients participated in the study with a male-to-female ratio of 1:1.5. Seventy-eight (60.5%) patients had systemic hypertension as a comorbid condition while the remaining were being managed for diabetes mellitus alone. Only 6 (4.7%) of the patients had type 1 DM while the remaining 123 (95.3%) were diagnosed with type 2 DM. Metformin was the most prescribed oral hypoglycaemic agent (n = 111, 58.7%) followed by glibenclamide (n = 49, 25.9%). Medication adherence was classified as good, medium, and poor for 52 (40.6%), 42 (32.8%), and 34 (26.6%) patients, respectively.Medication costs accounted for 72.3% of the total direct cost of DM in this study, followed by the cost of laboratory investigations (17.6%).

Conclusion

Adherence of diabetes patients in the study sample to their medications was satisfactory. There is a need for the integration of generic medicines into routine care as a way of further reducing the burden of healthcare expenditure on the patients.  相似文献

Background

Currently, oesophageal cancer is not a public health priority disease in Sub-Saharan Africa.

Aim

Analysis of published scientific studies regarding oesophageal cancer in Sub-Saharan Africa was done to ascertain the incidence, prevalence and geographical distribution of the disease in the region.

Methods

A pub med literature search was conducted for articles ranging from 1950 to 2009 database involving the following key words: oesophageal carcinoma, incidence, prevalence and sub-Saharan Africa.

Results

54 articles were retrieved, of which 16 were analyzed. Differences in the study methodologies used made the comparison amongst studies difficult. Overall, however, studies show that oesophageal cancer is on the increase in the region with its epicenter in the eastern and southern Africa. Incidence of the disease is higher in males than females and is prominent among 45–64 years age group in both sexes. Squamous cell carcinoma is a cell type more common than adenocarcinoma.

Conclusion

Oesophageal cancer is on the increase in the Sub-Saharan African Region with uneven geographical distribution. Therefore, countries in the region are encouraged together with global health organizations to include oesophageal cancer amongst diseases of public health importance for effective prevention, early diagnosis and effective treatment.  相似文献

Background

A study was undertaken with the aim to evaluate the therapeutic and clinical efficacy of oral appliances in the management of upper airway sleep disorders like snoring and obstructive sleep apnea (OSA).

Methods

Oral appliances were prescribed in eight cases of non - apneic snoring and 42 polysomnography (PSG) diagnosed cases of OSA. The cases were assessed on Epworth Sleepiness Scale (ESS) and Apnea - Hypopnea Index (AHI).

Result

62.5% of the non - apneic snoring cases reported gross reduction/cessation of snoring. In the OSA cases, the mean AHI and ESS scores decreased from 51.48 ± 23.70 to 32.78 ± 18.06 and 12.50 ± 3.57 to 7.20 ± 2.917 respectively. A statistically significant (p<0.0001) improvement in AHI and ESS scores was observed.

Conclusion

Short term therapeutic efficacy of oral appliances therapy in non-apneic snoring and OSA cases was observed.Key Words: Snoring, Obstructive sleep apnea, Oral appliances  相似文献

Aims

There is a critical shortage of Orthopedic Surgeons in Malawi as well as all countries in sub-Saharan Africa. To date, there is no published literature that has investigated surgical or Orthopedic career selection amongst African medical trainees. With the goal of facilitating recruitment into Surgery and Orthopedics in Malawi, we explored the key aspects of Malawian Medical Students'' choice of careers in surgical disciplines.

Methods

An on-line survey of all students in clinical years at the College of Medicine in Blantyre, Malawi was performed. The survey was anonymous and constructed de novo by a stringent process including Item Generation, Item reduction, Survey composition, Pre-testing, Assessment of Validity by a recognized survey expert, Pilot testing in on-line format by several Malawian Medical Students, and then formal survey testing.

Results

Surgery was the most popular specialty choice among the medical trainees (46%). General Surgery was the popular surgical specialty (27%), followed by Neurosurgery (22%) and Orthopedics (19%). The majority of students (67%) feared occupational exposure to HIV but this did not appear to be a factor in specialty choice (p=0.9). Students with Orthopedic mentors were significantly more likely to choose Orthopedics as their first choice surgical specialty (p = 0.01). Despite limited resources and surgeons in sub-Saharan Africa, surgical specialties are desirable career choices.

Conclusions

This is the first evaluation of factors involved in surgical or Orthopedic career selection in any African context. Future initiatives to improve exposure and mentorship in Orthopedics are fundamental to recruitment into the specialty.  相似文献

Objective

Poor adherence to complex multimodal therapies is a widely recognized problem in the daily care of dialysis patients, contributing to excess morbidity and mortality of this population. While a few studies have been devoted to understanding patient nonadherence, their results were somewhat controversial. The goals of this review are to quantify nonadherence to certain oral medications, to raise awareness of factors that may cause problems in a patient''s adherence to this treatment, and to describe strategies that may be used to improve adherence to prescribed pharmacotherapy.

Methods

A systematic literature review in the MEDLINE and PubMed database (1971-2008) was performed. Quantitative studies, which accurately indicated the total percentages of nonadherence to oral medication in adult patients receiving chronic hemodialysis, were identified.

Results

A total of 19 studies fulfilled the search criteria. Rates of nonadherence to the oral medication ranged from 3 - 80%. More than half of the included studies reported nonadherence rates of ≥ 50% (mean 67%). The use of phosphate binding therapy was the prevalent surveyed oral medication. Self reports, structured interviews, and predialysis serum phosphate levels were the most frequent assessment tools used to record adherence rates. Limitations of the reviewed studies included small patient cohorts, inconsistent definitions of adherence, and a lack of standardized methods for measuring nonadherence.

Conclusions

Nonadherence to oral medication in hemodialysis patients is still an underestimated, but life-threatening behaviour.  相似文献

Background

Systemic treatment of head and neck squamous cell carcinoma (HNSCC) includes a variety of antineoplastic drugs. However, drug-resistance interferes with the effectiveness of chemotherapy. Preclinical testing models are needed in order to develop approaches to overcome chemoresistance.

Methods

Ten human cell lines were obtained from HNSCC, including one with experimentally-induced cisplatin resistance. Inhibition of cell growth by seven chemotherapeutic agents (cisplatin, carboplatin, 5- fluorouracil, methotrexate, bleomycin, vincristin, and paclitaxel) was measured using metabolic MTT-uptake assay and correlated to clinically-achievable plasma concentrations.

Results

All drugs inhibited cell growth in a concentration-dependent manner with an IC50 comparable to that achievable in vivo. However, response curves for methotrexate were unsatisfactory and for paclitaxel, the solubilizer cremophor EL was toxic. Cross-resistance was observed between cisplatin and carboplatin.

Conclusion

Chemosensitivity of HNSCC cell lines can be determined using the MTT-uptake assay. For DNA-interfering cytostatics and vinca alkaloids this is a simple and reproducible procedure. Determined in vitro chemosensitivity serves as a baseline for further experimental approaches aiming to modulate chemoresistance in HNSCC with potential clinical significance.  相似文献

Background

Contact Endoscopy is a non invasive tool to visualise alterations in cell architecture in vivo. In this study we investigated the diagnostic accuracy of Contact Endoscopy in detecting malignancy in oral mucosal lesions.

Methods

76 patients with oral mucosal lesions requiring biopsy were included. Contact Endoscopy was performed by Otolaryngologist before biopsy and findings recorded. The lesion was then biopsied and sent for histopathological examination by Pathologist who was blinded to Contact Endoscopy findings. Findings of Contact Endoscopy were compared with histopathological findings taking the latter as the gold standard. Two biopsies were reported as ‘inconclusive’ on histopathological examination and hence excluded from the final analysis. Data of the remaining 74 patients is presented here.

Results

Clinically lesions were diagnosed as ulcero-proliferative lesions in 34 patients, Leukoplakia in 19, Erythroplakia in 9, Lichen planus in 5 and Submucous fibrosis in 7 patients. Histopathological examination revealed presence of malignancy in 97.06% of ulcero-proliferative mucosal lesions, 10.53% of leukoplakia and 33.33% of erythroplakia while corresponding figures on Contact Endoscopy were 94.12%, 5.26% and 11.11% respectively. No malignancy was detected in lichen planus and submucous fibrosis by either technique. When compared with histopathological examination, CE showed sensitivity of 84.21%, specificity of 94.44% and accuracy of 89.19%. No adverse effects on the patients were seen due to the procedure or stain.

Conclusion

Contact Endoscopy may be useful in determining cellular structure in vivo without biopsy to detect oral malignancy early. Further studies are suggested.  相似文献

Background

Breast cancer is the most common female cancer in Africa, yet no published studies have investigated breast cancer in Malawi. Understanding the clinical profile of breast cancer is important to develop early diagnosis efforts.

Aim

To describe clinical and pathological characteristics of breast specimens from a pathology laboratory at a national teaching hospital.

Methods

Secondary analysis of pathology reports from July 2011 to September 2013.

Results

Among 85 breast cancer cases, 55% were < 50 years. Median tumor size was 4 cm and 49% were grade 3. Median symptom duration was eight months.

Conclusions

Malawian women with breast cancer commonly have long symptom durations prior to diagnosis, young age, and poorly differentiated tumors. Improved clinical and pathological characterization, including hormone receptor status, are urgently needed to better understand this disease in Malawi.  相似文献

Background

Isotretinoin, an oral retinoid, has been utilized to achieve long term remissions in cases of recalcitrant acne. In the conventional dosage schedule, the use of oral isotretinoin has been limited by the occurrence of biochemical abnormalities such as hypertriglyceridaemia and impaired liver function tests and radiological changes consistent with diffuse idiopathic skeletal hyperostosis. Low-dose intermittent regimen of oral isotretinoin has been evolved as a cost effective alternative to the conventional dosage regimen in cases of acne. This study addresses the issue of adverse effects of low-dose intermittent isotretinoin and the safety of this regimen.

Methods

A total of 60 cases of recalcitrant acne were included in the study. Baseline haematological, biochemical and radiological investigations were carried out. Low-dose intermittent isotretinoin was instituted in a dose of 0.5 mg/kg/day for one week in every four weeks for six months. The investigations were repeated at the end of six months therapy.

Result

High triglyceride levels occurred in 5% of cases whereas impaired liver function tests and skeletal hyperostosis of the spine were not observed in any case after low-dose intermittent isotretinoin.

Conclusion

The low-dose intermittent regimen in cases of acne may be utilized to limit the systemic toxicity of oral isotretinoin.Key Words: Recalcitrant acne, Isotretinoin, Low-dose intermittent regimen  相似文献

Objective

To investigate the surface architecture of the asymmetrical buccal cavity of Solea solea which are considered one of the most important predators in benthic communities.

Methods

Adult Solea solea were obtained from Mediterranean Sea near Damietta. The heads were removed and processed for scanning electron microscopy. Its buccal cavity is asymmetrical and divided into roof and floor and the tongue for histological studies.

Results

The buccal cavity roof is formed from upper jaw, velum and the palate. The upper jaw has several wing like processes with teeth arranged in several rows which may help in cutting and pushing the food to the entrance of the digestive canal while the floor is formed from the lower jaw and the tongue. The tongue is divided into apex, body and root. There is a gradual decrease of goblet cells in the tongue from anterior to posterior. These goblet cells function in protection of the epithelium.

Conclusions

Teeth in the floor of the buccal cavity and taste buds can be considered adaptive changes of the oral cavity related to the feeding habits and was a source to identify new and better methods of nutrition in aquaculture of Solea solea.  相似文献

Objective

Primary open angle glaucoma (POAG) is the most common type of glaucoma in Africa. We carried out a study to determine the clinical presentation pattern of patients with primary open angle glaucoma (POAG) at a tertiary hospital in Malawi.

Design

A cross-sectional study

Setting

Lions Sight First Eye Hospital—a major referral and teaching state eye hospital in Blantyre, Malawi

Subjects

Study participants were newly diagnosed POAG patients at specialist eye clinic during study period.

Results

A total of 60 POAG patients were recruited into the study. The mean age was 58.7 years (SD= 16.6, range 18 - 86). There were more male (44, 73.3%) than female (16, 27.7%) patients. The majority of patients (73%) presented one year after onset of visual symptoms. Twenty-six patients (43%) had unilateral blindness (visual acuity < 3/60; WHO classification), while nine patients (15%) presented with bilateral blindness. A vertical cup-to-disc ratio (CDR) of 0.8 or worse was seen in 92 eyes (79%). The mean intraocular pressure (IOP) reading was 35.5 mmHg (SD 13.30). Of the thirty-three eyes that successfully underwent visual field analysis, very advanced defects were recorded in 12 eyes (36%).

Conclusion

This study demonstrates delayed presentation and male predominance among POAG patients at a tertiary eye hospital in Malawi. Glaucoma intervention programmes should aim at identifying patients with treatable glaucoma with particular attention to women.  相似文献

Objective

To compare the two methods of rapid diagnostic tests (RDTs) and microscopy in the diagnosis of malaria.

Methods

RDTs and microscopy were carried out to diagnose malaria. Percentage malaria parasitaemia was calculated on thin films and all non-acute cases of plasmodiasis with less than 0.001% malaria parasitaemia were regarded as negative. Results were simply presented as percentage positive of the total number of patients under study. The results of RDTs were compared to those of microscopy while those of RDTs based on antigen were compared to those of RDTs based on antibody. Patients'' follow-up was made for all cases.

Results

All the 200 patients under present study tested positive to RDTs based on malaria antibodies (serum) method (100%). 128 out of 200 tested positive to RDTs based on malaria antigen (whole blood) method (64%), while 118 out of 200 patients under present study tested positive to visual microscopy of Lieshman and diluted Giemsa (59%). All patients that tested positive to microscopy also tested positive to RDTs based on antigen. All patients on the second day of follow-up were non-febrile and had antimalaria drugs.

Conclusions

We conclude based on the present study that the RDTs based on malaria antigen (whole blood) method is as specific as the traditional microscopy and even appears more sensitive than microscopy. The RDTs based on antibody (serum) method is unspecific thus it should not be encouraged. It is most likely that Africa being an endemic region, formation of certain levels of malaria antibody may not be uncommon. The present study also supports the opinion that a good number of febrile cases is not due to malaria. We support WHO''s report on cost effectiveness of RDTs but, recommend that only the antigen based method should possibly, be adopted in Africa and other malaria endemic regions of the world.  相似文献

Background

Marjolin''s ulcer is a rare, aggressive condition that arises on chronic skin lesions and diseases. Inthis article, we will report 83 cases of this disease.

Methods

Retrospectively, we retrieved 83 records of patients with cancer arising from chronic skin conditions.Data concerning demography, type of original skin insult, time interval between original lesion and cancer,cancer histology, and lymph node involvement were recorded.

Results

The mean age was 55.30 years (range: 21-90). There were 51 males (61.5%) and 32 females (38.5%).Foot was the most prevalent site of primary skin lesion (49.4%) followed by scalp (15.6%). Original skin insultswere burn (87.9%), osteomyelitis (2.4%), radiation (2.4%), electrical burn (1.2%), surgical scar (2.4%),pemphigus (1.2%), bite (1.2%), and bed sore (1.2%). Histologic diagnosis were well differentiated SCC(38.6%), SCC, differentiation not reported (24.1%), moderately differentiated SCC (13.2%), BCC (9.6%), poorlydifferentiated SCC (6.0%), melanoma (2.4%), verrucous carcinoma (2.4%), MFH (1.2%), mucoepidermoidcarcinoma (1.2%), and leiomyosarcoma (1.2%). Most of the cases occurred more than 20 years after the initialskin insult. There were 6 (7.2%) cases that developed within 1 year (acute Marjolin''s Ulcer). Forty three patients(69.3%) had palpable regional lymph nodes.

Conclusion

Data in this series were in confirmation with many other reports. Marjoln''s ulcer should be consideredas a significant post-skin injury complication.  相似文献

Background

To evaluate the diagnostic potential of saline infusion sonography to pick up uterine cavity lesions and compare it with the gold standard office hysteroscopy.

Methods

Study population consisted of women scheduled for office hysteroscopy for various indications. Uterine cavity of 208 women of the study group were evaluated first by saline infusion sonography and then by office hysteroscopy by two separate examiners. Findings were recorded separately for both procedures and compared. Pain rating was also noted after each procedure. Result: In eight patients either or both the procedures could not be performed for various reasons, hence were excluded from the analysis. With saline infusion sonography, pathological findings were identified in 93 (46.5%) patients and hysteroscopy detected lesions in 88 (44%) patients. For all findings combined sensitivity of saline infusion sonography was 90.9%, specificity 88.3%, positive predictive value 86.0% and negative predictive value 92.5% as compared to hysteroscopy. Former was less painful and easier to perform than the latter.

Conclusion

The findings of saline infusion sonography and office hysteroscopy did not differ significantly. Thus saline infusion sonography is an excellent option for uterine cavity evaluation.Key Words: Hysteroscopy, Saline infusion sonography, Uterine cavity abnormality  相似文献

Background

Abnormal uterine bleeding (AUB) accounts for 33% of female patients referred to gynaecologists. Common causes of AUB include endometrial polyps, endometrial hyperplasia, submucous fibroids and anovulation. Accurate diagnosis of the cause of AUB can reduce the frequency of hysterectomy. This study was aimed at assessing the usefulness of TVS in comparison with hysteroscopy in AUB evaluation.

Methods

100 female patients with AUB were enrolled in the study. Each patient was subjected to TVS where uterine cavity was studied in detail and hysteroscopy under anaesthesia using saline as distension medium. Sensitivity, specificity and predictive value of TVS as compared to hysteroscopy were calculated. Subgroup analysis within each group was also performed.

Results

Menorrhagia was the commonest presenting symptom in the study population (n = 58) followed by metrorrhagia, menometrorrhagia and continuous bleeding >21 days. 74 female patients had normal size uterus. In 57 patients, the uterine cavity was normal on TVS. Thickened endometrium, endometrial polyp and submucous fibroids were seen in 19, 16 and 6 patients respectively. Hysteroscopy showed normal cavity in 59 female patients and polypoidal endometrium, polyps or submucous fibroids in 41. TVS was found to have high sensitivity and specificity (95.23 and 94.82 respectively) and high positive and negative predictive value. Strength of agreement between TVS and hysteroscopy was high (kappa value 0.898).

Conclusion

TVS is recommended as first line investigation in AUB. If TVS shows normal cavity, further evaluation can be omitted and patient started directly on medical treatment for her symptoms.  相似文献

Background

Incidence of drug resistance and pattern of susceptibility to antitubercular drugs in pulmonary tuberculosis amongst soldiers and their families was studied for four years at a military hospital in northwest India.

Methods

Identification and susceptibility tests were carried out as per procedures laid out in laboratory manual of Tuberculosis Research Centre (TRC), Chennai.

Results

Of the 172 strains of Mycobacterium tuberculosis (MTB) isolated from sputum samples, 150 (87.21%) were sensitive and 22 (12.79%) showed resistance to one or more antitubercular drugs. Acquired drug resistance was observed in 7 (31.82%) and primary drug resistance in 15 (68.18%) cases. Among 22 drug resistant cases, who were on short course chemotherapy (SCC), resistance to single drug was observed in 12 (54.54%), two drugs in 7 (31.82%) and to three or more drugs in 3 (13.64%) isolates. Fourteen (18.14%) strains were resistant to Streptomycin, 8 (4.65%) to Rifampicin, 11 (6.40%) to Isoniazid, 1 (0.58%) to Pyrazinamide and 2 (1.16%) to Ethambutol. Multidrug resistance was observed in 5 (2.91%) cases, of which resistance to Isoniazid and Rifampicin was present in 2 (1.16%) and their combination with other drugs in other 3 (1.74%) isolates.

Conclusions

Drug susceptibility pattern to antitubercular drugs is discussed and compared with studies from other centres.Key Words: Drug resistance, Antitubercular drugs, Mycobacterium tuberculosis  相似文献

Background

Trends in mode of detection of HIV infection in the Armed Forces required to be analyzed to formulate future strategies for early detection.

Methods

A retrospective study was thus conducted in 612 newly diagnosed HIV-positive cases between January 1997 to August 2002.

Results

182(29.74%) patients had already developed Category C conditions when detected to be HIV-positive, 176(96.70%) with mycobacterial disease, majority (67.61%) of them being pulmonary tuberculosis, followed by recurrent bacterial pneumonia in 3 (1.65%), pneumocystis carinii pneumonia (PCP) in 2(1.1%) and oesophageal candidiasis in one (0.55%). Herpes zoster was the third most common mode of detection accounting for 86 (14.05%) of the cases (24.6% of them with involvement of ophthalmic branch of trigeminal nerve), after tuberculosis in 176(28.76%) and blood donors in 98(16.01%), followed by constitutional symptoms in 59(9.64%) cases, investigation for STDs in 56(9.15%), bacterial pneumonia in 6(0.98%) and oral mucosal candidiasis in only one (0.16%) case. None was detected during acute retroviral illness and only 5(0.82%) cases were detected while being investigated for generalized lymphadenopathy. Amongst the cases detected during investigation for STDs, majority (26.79%) were on STD surveillance. 22(3.60%) cases tested positive when their spouses were detected to be HIV-positive, 20(3.27%) while being screened for surgery, 4(0.65%) for posting abroad and 2(0.32%) each during investigation when child was found HIV-positive and investigation for HBV infection. Remaining 69(11.27%) patients were detected during investigation of various related or unrelated conditions including one (0.16%), which reported voluntarily after a high-risk exposure.

Conclusion

There is a need to encourage voluntary reporting and identify more number of cases during acute retroviral syndrome and PGL stage.Key Words: HIV infection, Mode of detection  相似文献
