Elimination of malaria in country Georgia

Malaria is well known in Georgia since ancient times, causing national disasters with associated significant mortality and economic losses. By 1970 Georgia managed to reach complete and sustained elimination of the disease as a result of comprehensive anti-malaria measures undertaken in the country. However from the mid-1990s, economic collapse following disintegration of Soviet Union causing breakdown of important public health networks including anti-malaria preventive and control infrastructure resulted in gradual increase of malaria cases in the country with a peak of 437 and 474 cases in 2001 and 2002, respectively. From 2000 two major anti-malaria efforts were carried out by National Center for Disease Control and Public Health, WHO and Global Fund to Fight AIDS, tuberculosis and malaria and as result of comprehensive and collaborative work in 2010 the level of zero cases of local mosquito-borne malaria transmission was achieved and the country entered the elimination phase.     

Left atrial metastases of poorly differentiated thyroid carcinoma diagnosed by echocardiography and magnetic resonance imaging--case report and review of literature

Intracardiac metastases of thyroid carcinoma are a rare event. Their incidence is low in large autopsy series, and antemortem diagnosis is even less common. We present the case of a woman with advanced poorly differentiated thyroid carcinoma who had extensive intracardiac metastases. This case highlights the usefulness of echocardiography and magnetic resonance imaging in the diagnosis and differential diagnosis of cardiac metastases.     

Pituitary deficiency after aneurysmal subarachnoid hemorrhage

OBJECTIVE:

Aneurysmal subarachnoid hemorrhage puts patients at high risk for the development of pituitary insufficiency. We evaluated the incidence of pituitary dysfunction in these patients and its correlation with clinical outcome.

METHODS:

Pituitary function was tested in 66 consecutive patients in the first 15 days after aneurysmal subarachnoid hemorrhage. The following were measured in all patients: thyroid-stimulating hormone, free thyroxine, triiodothyronine, luteinizing hormone, follicle-stimulating hormone, total testosterone (in males), estradiol (in females), prolactin, serum cortisol, plasma adrenocorticotropic hormone, growth hormone and insulin growth factor.

RESULTS:

The endocrine assessment was made at a mean of 7.4 days (standard deviation ±6.6) after subarachnoid hemorrhage. Forty-four (66.7%) female and 22 (33.3%) male patients were evaluated. Thirty-nine patients (59.1%) had some type of pituitary dysfunction. Follicle-stimulating hormone/luteinizing hormone deficiency was the most frequent disorder (34.8%), followed by growth hormone/insulin growth factor (28.7%), adrenocorticotropic hormone (18.1%) and thyroid-stimulating hormone (9%). Seventeen (25.7%) patients showed deficiencies in more than one axis. A greater incidence of hormone deficiency was observed in patients with a Glasgow Coma Scale score ≤13 (t test, p = 0.008), Hunt-Hess grade ≥4 (t test, p<0.001), or Fisher grade 4 (t test, p = 0.039). Hormone deficiency was not significantly associated (p>0.05) with increased hospitalization or clinical outcome.

CONCLUSION:

Pituitary dysfunction was identified in a substantial portion of patients with previous aneurysmal subarachnoid hemorrhage, but no association was found between this dysfunction and poor clinical outcome.     

Rabies: relevance, prevention, and management in travel medicine

Rabies is a zoonotic viral disease, transmitted only in mammals. Terrestrial rabies, predominantly transmitted by dogs, is the most important rabies cycle threatening humans. The causative neurotropic virus is a negative-stranded RNA virus of the family Rhabdoviridae, genus Lyssavirus. This genus contains several rabies-related viruses. All variants are known or suspected to cause rabieslike diseases. Transmission occurs by the virus entering through the skin or the mucosa after bites, scratches, or preexisting injuries contaminated by the saliva of an infected mammal. Only 51 human rabies cases that have not been transmitted by animal bites are described.     

Bariatric surgery in patients with liver cirrhosis

BackgroundData regarding the management of bariatric patients with cirrhosis are scarce, and there is no strong evidence that supports a specific approach for this group of patients. The aim of this study was to review our experience with cirrhotic patients undergoing bariatric surgery.MethodsA prospectively maintained database was reviewed to assess the outcomes of bariatric surgery for patients with known cirrhosis and for patients with cirrhosis discovered at surgery (unknown cirrhosis).ResultsFrom April 2004 to September 2011, 23 patients (12 with known cirrhosis and 11 with unknown cirrhosis) met inclusion criteria. There were 14 females and 9 males with a mean age of 51.5±8.3 and a mean body mass index of 48.2±8.6 kg/m2. Child-Pugh classes were A (n = 22) and B (n = 1). Patients had a high frequency of diabetes (83%), dyslipidemia (61%), and hypertension (83%). Procedures performed were laparoscopic Roux-en-Y gastric bypass (LRYGB) (n = 14), laparoscopic sleeve gastrectomy (LSG) (n = 8), and laparoscopic adjustable gastric banding (n = 1). Two patients underwent LSG successfully after transjugular intrahepatic portosystemic shunt. Mean length of hospital stay was 4.3±2.7 days. Complications developed in 8 patients. One patient died of unknown cause 9 months after surgery. No patients had liver decompensation after surgery. The patients lost 67.4%±30.9% of their excess weight at 12 months follow-up and 67.7%±24.8% at 37 months follow-up.ConclusionLRYGB and LSG can be performed without prohibitive complication rates in carefully selected patients with cirrhosis. In our experience, bariatric patients with cirrhosis achieved excellent weight loss and improvement in obesity-related co-morbidities.
