Risk factors for carriage of Streptococcus pneumoniae in children.

BACKGROUND: During the past decades Streptococcus pneumoniae has developed significant resistance to many classes of antimicrobial drugs. Potential risk factors for colonization of the nasopharynx by Streptococcus pneumoniae in children and for carriage of drug resistant strains were examined. METHODS: Between 2007 and 2008 nasopharyngeal swabs were collected from 402 children 6 months to 5 years old visiting the public sector immunization centers and outpatient departments as well as offices of paediatricians from private practice in Nicosia district in Cyprus. Information on demographic characteristics and potential risk factors of participating children were collected using a standardized questionnaire distributed to parents. RESULTS: In multivariable analyses we found that attendance at day care center, having siblings in the family and having both parents originating from Cyprus, statistically increased the risk of pneumococcal colonization. Full immunization with PCV7 appears to be a protective factor against colonization by pneumococcus. Previous administration of antimicrobials during the last month prior to specimen collection appeared to be the most consistent risk factor for carrying a non susceptible strain of Streptococcus pneumoniae to either penicillin or erythromycin. Factors such as age, nationality, previous or current breastfeeding, passive exposure to cigarette smoke and attendance in a day care center do not appear as independent risk factors for colonization by non susceptible strains. CONCLUSIONS: Prudent use of antibiotics especially for upper respiratory tract infections in children as well as increased vaccination coverage by the pneumococcal conjugate vaccines could prove effective in reducing levels of colonization by drug resistant pneumococcal strains.

Lymphadenitis by non-tuberculous mycobacteria in children.

BACKGROUND: Non-tuberculous mycobacteria (NTM) constitute an important cause of cervical lymphadenitis in immunocompetent children. The aims of this study were to estimate the incidence of lymphadenitis due to NTM in children in Cyprus and to describe the characteristics, diagnostic approach, management and outcome of such infections. METHODS: Children aged 1-5 years old, evaluated at Archbishop Makarios III Hospital, Nicosia, Cyprus, from 1 January 2007 to 31 December 2016 for lymphadenopathy, were included in the study. All children had positive lymph node culture for NTM. RESULTS: A total of 22 cases of culture-positive lymphadenitis caused by NTM were reviewed. Patient age ranged from 16 to 55 months. Tuberculin skin test produced an induration in 81.0% of cases (diameter, 4-17 mm). Mycobacterium avium was isolated in 17 cases (77.3%), M. intracellulare in three (13.6%), M. paraffinicum in one (4.5%) and M. kansasii in one case (4.5%). All 22 patients underwent surgical excision of affected nodes. Additional anti-mycobacterial treatment was given when complete excision was not achieved or for post-surgical recurrence. Complications were few and included scar in three children and one case of transient facial nerve palsy. CONCLUSION: Surgical excision of NTM-infected lymph nodes is an effective diagnostic and therapeutic approach. When total surgical excision is not feasible, a combination of partial excision with a clarithromycin-including drug regimen appears safe, effective and causes milder and fewer complications than surgery alone.

Meningococcal disease in the Middle East: A report from the Global Meningococcal Initiative.

This review details recent findings from the Global Meningococcal Initiative's (GMI) recent meeting on the surveillance and control strategies for invasive meningococcal disease in the Middle East. The nature of case reporting and notification varies across the region, with many countries using bacterial meningitis as an IMD case definition in lieu of meningitis and septicaemia. This may overlook a significant burden associated with IMD leading to underreporting or misreporting of the disease. Based on these current definitions, IMD reported incidence remains low across the region, with historical outbreaks mainly occurring due to the Hajj and Umrah mass gatherings. The use of case confirmation techniques also varies in Middle Eastern countries. While typical microbiological techniques, such as culture and Gram staining, are widely used for characterisation, polymerase chain reaction (PCR) testing is utilised in a small number of countries. PCR testing may be inaccessible for several reasons including sample transportation, cost, or a lack of laboratory expertise. These barriers, not exclusive to PCR use, may impact surveillance systems more broadly. Another concern throughout the region is potentially widespread ciprofloxacin resistance since its use for chemoprophylaxis remains high in many countries.

Epidemiology and risk factors for resistance to treatment of Kawasaki disease in Cyprus.

Kawasaki disease (KD) is one of the most common vasculitides of early childhood. There are no previous studies on KD in Cyprus. The aim of this study was to evaluate the epidemiology of KD in Cyprus, risk factors for resistance to treatment and the development of cardiac complications. This is a retrospective multicenter study of pediatric patients with KD hospitalized between January 2000 and-December 2019. The data were collected from medical records. A total of 136 patients with KD were included in the study. 83% of patients were < 5 years of age and 10% were < 6 months. Thirty patients (22%) developed coronary artery lesions. Serum sodium ≤ 133 mmol/L, albumin ≤ 3.2 g/dl, ALT ≥ 80 U/L and neutrophils percentage ≥ 80% at diagnosis, were identified as risk factors for resistance to IVIG. Clinical and epidemiological characteristics of KD in Cyprus population were similar to those reported in the literature. Although the majority of cases received appropriate treatment in time, cardiac complications still occurred.

Hemophagocytic lymphohistiocytosis associated with Epstein Barr virus and Leishmania donovani coinfection in a child from Cyprus.

We present a case of a 9-month-old girl from Cyprus with hemophagocytic lymphohistiocytosis associated with Epstein Barr virus and Leishmania donovani coinfection. Treatment with liposomal amphotericin B resulted in a dramatic resolution of clinical and laboratory abnormalities. To our knowledge, this is the first reported case of a coinfection-associated hemophagocytic lymphohistiocytosis and the first clinical report of visceral leishmaniasis infection in Europe by L. donovani.

Mycoplasma pneumoniae as a cause of vulvar ulcers in a non-sexually active girl: a case report.

BACKGROUND: Non-sexually active young females very rarely develop genital ulcers. Such ulcers pose a diagnostic challenge as well as physical and emotional distress for patients and family; therefore, the search for their etiology requires exhaustive investigation. Several viruses such as Epstein-Barr virus have been associated with this entity; however, Mycoplasma pneumoniae has rarely been linked to such ulcers in the literature. We present a case of vulvar ulcers in a non-sexually active young girl during the course of pneumonia caused by Mycoplasma pneumoniae. CASE PRESENTATION: A 10-year-old non-sexually active girl of cypriot origin presented at a hospital with fever, dry cough, and acute vulvar ulcers. Laboratory investigations as well as imaging studies revealed Mycoplasma pneumoniae as the cause of her pneumonia and acute vulvar ulcers. CONCLUSIONS: Although a rare cause of vulvar ulcers, Mycoplasma pneumoniae should be considered in the differential diagnosis of acute vulvar ulcers coexisting with respiratory symptoms.

A cluster of four cases of cutaneous leishmaniasis by Leishmania donovani in Cyprus: a case series.

INTRODUCTION: Leishmaniasis is endemic in more than 95 countries and is the only tropical/subtropical vector-borne disease that has been endemic in Southern Europe for decades. To the best of our knowledge, this is the first case of cutaneous leishmaniasis by Leishmania donovani in a child and the first cluster with adult cases reported in Europe. CASE PRESENTATION: We describe a familial cluster of four cutaneous leishmaniasis cases among Greek Cypriots caused by L. donovani in a Paphos village, in Cyprus. A 6-year-old boy (Case number 1) had a persistent lesion in the left angle of his upper lip, a 60-year-old woman (Case number 2) presented with a 2 cm-diameter glabella lesion on her forehead, a 60-year-old man (Case number 3) developed a lesion on his moustache area and a 40-year-old woman (Case number 4) had a lesion on her neck. In Case number 3 the lesion was self-cured; the other cases recovered after surgical resection followed by liposomal amphotericin B (Case numbers 1 and 4) or thermotherapy and liposomal amphotericin B (Case number 2). CONCLUSIONS: This familial cluster of cutaneous leishmaniasis, due to the anthroponotic L. donovani, shows that the sand fly species responsible for transmitting this parasite species is found in the area around the three neighbouring houses involved. The factors favourable for the survival, spread and contact of the vector with people could be assessed in this area for the establishment of preventative measures to safeguard public health.
