Incidence, risk factors and clinical characteristics of extra-pulmonary tuberculosis patients: a ten-year study in the North of Iran.

OBJECTIVE: To determine the incidence of extra-pulmonary tuberculosis (EPTB) and examine the risk factors and the clinical features of the disease over a ten-year period. METHODS: Retrospective study of records of patients who were followed and registered in the TB registry programme in the health district of Gorgan, Iran from January 1, 2008, through December 31, 2017. RESULTS: Among 2280 TB records, 609 (26.71%) were EPTB. They were mostly female patients (53.7%) and residents in rural areas (56.5%) with a mean age of 40.55 years [±16]. The average age of female patients (37.55 years [±16.99]) was lower than of male patients (44.07 years [±20.59]). The median of the incidence rate was 7.5 per 100 000 inhabitants for EPTB; biopsy and pathology were the best methods for the detection of EPTB. The most frequent forms of EPTB were lymphatic TB (193/609 = 31.7%) and pleural TB (158/609 = 25.9%). In most cases (245/609 = 40.2%), one to three months elapsed between occurrence of symptoms and final confirmation of EPTB. The outcome of EPTB was weaker than of pulmonary TB (PTB). CONCLUSION: Our most important finding was the increasing incidence of EPTB, which shows the importance of attention to this disease. Lymph node and pleural tissue were the most commonly infected tissues. Skeletal TB presents a challenge in the diagnosis and treatment of EPTB.

OBJECTIF: Déterminer l'incidence de la tuberculose extra-pulmonaire (EPTB) et examiner les facteurs de risque et les caractéristiques cliniques de la maladie sur une période de dix ans. MÉTHODES: Etude rétrospective des dossiers des patients qui ont été suivis et enregistrés dans le programme d'enregistrement de la TB dans le district de santé de Gorgan, en Iran, du 1er janvier 2008 au 31 décembre 2017. RÉSULTATS: Parmi 2.280 enregistrements de TB, 609 (26,71%) étaient des EPTB. Il s'agissait principalement de femmes (53,7%) et de résidents des zones rurales (56,5%) avec un âge moyen de 40,55 ans [± 16]. L'âge moyen des patients de sexe féminin (37,55 ans [± 16,99]) était inférieur à celui des hommes (44,07 ans [± 20,59]). La médiane du taux d'incidence était de 7,5 pour 100.000 habitants pour l'EPTB; la biopsie et la pathologie étaient les meilleures méthodes pour la détection de l'EPTB. Les formes les plus fréquentes d'EPTB étaient la TB lymphatique (193/609 = 31,7%) et la TB pleurale (158/609 = 25,9%). Dans la plupart des cas (245/609 = 40,2%), un à trois mois s'étaient écoulés entre l'apparition des symptômes et la confirmation finale de l'EPTB. Le résultat de l'EPTB était plus faible que celui de la TB pulmonaire (PTB). CONCLUSION: Notre découverte la plus importante a été l'incidence croissante d'EPTB, ce qui montre l'importance de l'attention portée à cette maladie. Les ganglions lymphatiques et les tissus pleuraux étaient les tissus les plus fréquemment infectés. La TB osseuse présente un défi dans le diagnostic et le traitement de l'EPTB.

The effect of green tea extract supplementation on sputum smear conversion and weight changes in pulmonary TB patients: A randomized controlled trial.

BACKGROUND: Acceleration in sputum smear conversion helps faster improvement and decreased probability of the transfer of TB. In this study, we aimed to investigate the effect of green tea extract supplementation on sputum smear conversion and weight changes in smear positive pulmonary TB patients in Iran. METHODS: In this double blind clinical study, TB patients were divided into intervention, (n=43) receiving 500 mg green tea extract (GTE), and control groups (n=40) receiving placebo for two months, using balanced randomization. Random allocation and allocation concealment were observed. Height and weight were measured at the beginning, and two and six months post-treatment. Evaluations were performed on three slides, using the ZiehlNeelsen method. Independent and paired t test, McNemar's, Wilcoxon, Kaplan-Meier, Cox regression model and Log-Rank test were utilized. Statistical significance was set at p<0.05. This trial was registered under IRCT201212232602N11. RESULTS: The interventional changes and the interactive effect of intervention on weight were not significant (p>0.05). In terms of shortening the duration of conversion, the case to control proportion showed a significant difference (p=0.032). Based on the Cox regression model, the hazard ratio of the relative risk of delay in sputum smear conversion was 3.7 (p=0.002) in the higher microbial load group compared to the placebo group and 0.54 (95% CI: 0.31-0.94) in the intervention compared to the placebo group. CONCLUSION: GTE decreases the risk of delay in sputum smear conversion, but has no effect on weight gain. Moreover, it may be used as an adjuvant therapy for faster rehabilitation for pulmonary TB patients.

Follicular isolation technique with de-epithelialization for eyebrow and eyelash reconstruction.

BACKGROUND: The eyebrow and eyelash are two major sites in facial hair transplantation. Different methods have been experienced for better results. Surgeons tend to use smaller grafts. The authors modified the follicular isolation technique and added de-epithelialization to reduce complications and improve outcomes. METHODS: Sixty patients were allocated to either the isolation group or the isolation plus de-epithelialization group. Some patients underwent both eyebrow and eyelash transplantation; therefore, 79 procedures were performed on 60 patients. Scar formation, number and percentage of surviving transplanted hairs, hair growth orientation, and satisfaction with outcome were reviewed at 6 months. RESULTS: The mean number of preserved transplanted hairs in eyebrow transplantation at follow-up was not significantly different between the two groups, but the mean percentage of preserved transplanted hairs was significantly higher in the isolation plus de-epithelialization group. In eyelash reconstruction, the mean number and percentage of surviving hairs were significantly higher in the isolation + de-epithelialization group than in the isolation-only group. The isolation + de-epithelialization group had more cases of normal hair growth direction in both eyebrow and eyelash transplantation cases, although the difference was statistically significant only in eyebrow reconstruction. CONCLUSIONS: This study showed that follicular isolation plus de-epithelialization had better outcomes and fewer complications than did follicular isolation alone. This could be due to less need for suture in recipient sites, less risk for burying of epithelium of graft in the recipient site, less need for manipulation, lower graft volume, and less need for blood for survival and for removal of sweat glands. CLINICAL QUESTION/LEVEL OF EVIDENCE: : Therapeutic, II.

Crimean-Congo hemorrhagic fever: case series from a medical center in Golestan province, Northeast of Iran (2004).

Crimean-Congo hemorrhagic fever (CCHF) is a widely distributed lethal disease, worldwide. Humans are usually infected with CCHF virus through a tick bite or close contact with viral contaminated tissues or with blood of domestic animals or of infected patients. The present study reports six cases of CCHF, who were in contact with both infected tissues and blood from sheep. In some regions like Golestan province (North of Iran), clinician suspicion may have an important role in early diagnosis and treatment of the disease. Conservative therapy (intensive monitoring) and prescription of antiviral medication (Ribavirin) accompanied with corticosteroids, was useful at the early stage of CCHF.
