Management of accidental kerosene ingestion.

Accidental kerosene ingestion is still a common problem in Libya. It causes considerable morbidity and occasionally mortality. The role and choice of antibacterial agents in its management remain unsettled. Pulmonary damage has been reported as resulting from aspiration. In aspiration pneumonia, anaerobic organisms may be important pathogens and metronidazole may have a place in therapy. The present randomized trial in 100 children with accidental kerosene ingestion assesses the role of ampicillin, carbenicillin and metronidazole in its management. The results are not conclusive but chemoprophylaxis appears to decrease morbidity. Of the various regimens used, the ampicillin/metronidazole combination was found to be slightly better than the others. Further study is recommended.

Cystic fibrosis in Jews: frequency and mutation distribution.

The incidence of cystic fibrosis and the frequency of disease causing mutations varies among different ethnic groups and geographical regions around the world. The Jewish population is comprised of two major ethnic groups. Ashkenazi and Non-Ashkenazi. The latter is further classified according to country of origin. An extreme variability in the disease frequency (from 1:2400-1:39,000) was found among the different Jewish ethnic groups. In the entire Jewish CF population, only 12 mutations were identified that altogether enable the identification of 91% of the CF chromosomes. However, in each Jewish ethnic group, the disease is caused by a different repertoire of a small number of mutations. In several ethnic groups, there is a major CFTR mutation that accounts for at least 48% of the CF chromosomes. High proportion of the CF chromosomes can be identified in Ashkenazi Jews (95%), Jews originating from Tunisia (100%), Libya (91%), Turkey (90%), and Georgia (88%). High frequencies of CFTR mutations were found among infertile males with CBAVD who might not have additional CF clinical characteristics. Of the Jewish males with CBAVD, 77% carried at least one CFTR mutation. The 5T mutation is the major mutation in Jewish CBAVD affecteds accounting for 32% of the chromosomes among Ashkenazi Jews and 36% among the non-Ashkenazi Jews. Five additional CFTR mutations, W1282X (12%), delta F508 (9%), N1303K (3%), D1152H, (5%)), and R117H (1%) were identified among Ashkenazi Jews with CBAVD. Only two mutations, delta F508 and R117H, were found among non-Ashkenazi males with CBAVD. An increased frequency of the 5T allele was also found among Jewish patients with atypical CF presentation, 18% in Ashkenazi, and 10% in non-Ashkenazi Jews. In summary, we present the required information for genetic counseling of Jewish families with typical and atypical CF and for carrier screening of healthy Jewish individuals.

Arabic sign language: a perspective.

Sign language in the Arab World has been recently recognized and documented. Many efforts have been made to establish the sign language used in individual countries, including Jordan, Egypt, Libya, and the Gulf States, by trying to standardize the language and spread it among members of the Deaf community and those concerned. Such efforts produced many sign languages, almost as many as Arabic-speaking countries, yet with the same sign alphabets. This article gives a tentative account of some sign languages in Arabic through reference to their possible evolution, which is believed to be affected by the diglossic situation in Arabic, and by comparing some aspects of certain sign languages (Jordanian, Palestinian, Egyptian, Kuwaiti, and Libyan) for which issues such as primes, configuration, and movement in addition to other linguistic features are discussed. A contrastive account that depicts the principal differences among Arabic sign languages in general and the spoken language is given.

Global overview of injecting drug use and HIV infection among injecting drug users.

OBJECTIVE: To provide global estimates of the prevalence of injecting drug use (IDU) and HIV prevalence among IDU, in particular to provide estimates for developing and transitional countries. METHODS: Collation and review of existing estimates of IDU prevalence and HIV prevalence from published and unpublished documents for the period 1998-2003. The strength of evidence for the information was assessed based on the source and type of study. RESULTS: Estimates of IDU prevalence were available for 130 countries. The number of IDU worldwide was estimated as approximately 13.2 million. Over ten million (78%) live in developing and transitional countries (Eastern Europe and Central Asia, 3.1 million; South and South-east Asia, 3.3 million; East-Asia and Pacific, 2.3 million). Estimates of HIV prevalence were available for 78 countries. HIV prevalence among IDU of over 20% was reported for at least one site in 25 countries and territories: Belarus, Estonia, Kazakhstan, Russia, Ukraine, Italy, Netherlands, Portugal, Serbia and Montenegro, Spain, Libya, India, Indonesia, Malaysia, Myanmar, Nepal, Thailand, Viet Nam, China, Argentina, Brazil, Uruguay, Puerto Rico, USA and Canada. CONCLUSIONS: These findings update previous assessments of the number of countries with IDU and HIV-infected IDU, and the previous quantitative global estimates of the prevalence of IDU. However, gaps remain in the information and the strength of the evidence often was weak.

Attracting adult New World screwworm, Cochliomyia hominivorax, to odour-baited targets in the field.

A field study in Libya investigated aspects of Cochliomyia hominivorax behaviour relevant to the operation of a target-based control system. Flies were readily caught by electrified targets, but only when baited with the attractant 'swormlure-4'. Target size (0.25-1 m2) did not affect catch, but black targets caught twice as many flies as red ones. Omitting the most volatile component of swormlure-4, dimethyl disulphide, significantly reduced catches of both sexes of C.hominivorax in wind-orientated traps, but only reduced the capture of females significantly on targets. A new polythene sachet dispenser for odours was tested; four to six such sachets filled with swormlure-4 less dimethyl disulphide gave an equivalent catch to one of the standard bottle plus wick dispensers using the same attractant, although they dispensed odour at about half the rate. From direct observations, fewer than 40% of flies contacted the target for more than 10 s on any one visit. From catches on an intermittently-active electrocuting grid, it was calculated that there is a c. 40% rate of multiple contacts of flies with the target.

Severe autosomal recessive muscular dystrophy in an extended Sudanese kindred.

The clinical manifestations, biochemical, electrocardiographic, histological and histochemical features of a severe autosomal recessive muscular dystrophy (MD)--as seen in 15 members of a large Sudanese kindred, both male and female--are reported and discussed. The age of onset ranged from three to five years, the pattern of muscular weakness was similar to that of Duchenne MD and pseudohypertrophy was a remarkable feature. Both sexes became completely dependent by 16 years, and died at or before 20 years of age. The clinical picture in this family and the histological features are compared with those of Duchenne MD and with cases reported from Tunisia, Qatar and Libya. Certain clinical and histological features distinguish all of these types from each other and from the milder autosomal recessive MD of childhood which is more usual in the United Kingdom, Europe, Australia and North America.

Obstetric and gynaecological presentations of hydatid disease.

Hydatid disease of the female pelvis is rare in gynaecological practice. In Libya, where the disease is endemic, 14 women with pelvic hydatid disease were encountered in one hospital department between 1971 and 1979. Five of these women were pregnant, a hospital prevalence of 1 in 20 000. The other nine women accounted for 0.3% of all gynaecological laparotomies in the same hospital. The clinical features, diagnosis and management of this rare condition are described.

Bulgarian Jews in Israel: genetic blood markers. Red-cell antigens, serum proteins and red-cell isozymes.

Two hundred and sixteen unrelated Bulgarian Jews were typed for the following genetic systems: ABO, MNS, Rh, Kell and Duffy of the blood groups; ADA, AK1, ACP1, ESD, GLO, PGD, PGM1 and PGM2 of the red-cell enzymes, and for the serum proteins HP, GC and PI. A comparison of observed gene frequencies with those of two other Sephardi Jewish groups, from Libya and Morocco, disclosed significant heterogeneity in several systems. This was mostly due to Moroccan Jews differing from Bulgarian or from both the Libyan and Bulgarian Jews. A comparison of gene frequencies in Bulgarian Jews with those in Oriental Jews from Iraq and in Ashkenazi Jews from Poland disclosed a similarity between the three groups in Rh, ADA, GLO, PGM1 and HP. The frequencies for the above systems in the three groups were closer to those of Middle Easterners than to those of Europeans. A different pattern was observed for GC and PI, in which Bulgarian resembled Polish Jews and differed significantly from Iraqi Jews. This probably reflects an outcome of convergent adaptive processes.

Cardiac hydatid cyst in a child.

Presentation of hydatid disease is uncommon in children, and cardiac hydatid cyst is rare at any age. The authors discuss a pediatric patient with cardiac hydatid cyst in the posterior wall of the left ventricle. The cyst was diagnosed by two-dimensional echocardiography and by serology. A 3 month course of mebendazole therapy was only partially effective. The patient remains asymptomatic 2 years after diagnosis. HYDATID DISEASE is endemic in the Middle East. In a study from a surgical hospital in eastern Libya, the disease accounted for 0.89 percent of all hospital admissions. The echinococcus cyst grows very slowly and unless located in a critical anatomic site, it takes many years to evolve. Consequently, presentation in pediatric patients is distinctly uncommon. In an epidemiologic study from Benghazi, only 11.7 percent of patients were under 10 years old. Cardiac hydatid disease is rare at any age, accounting for less than 2 percent of all hydatid disease. Since the introduction of two-dimensional echocardiography, more cases are being diagnosed. All the reports in the recent literature are in adult patients. We report here, however, a cardiac hydatid cyst in the left ventricular wall in a child.

Further data on a 9.1-kb insertion-deletion polymorphism: survey of Mediterranean populations.

We report the distribution of a previously described 9.1-kb insertion-deletion polymorphism located on chromosome 22. We analyzed 1,844 individuals sampled from 26 Mediterranean populations in mainland Italy, Sicily, Sardinia, Tunisia, Libya, Morocco, Egypt, Greece, and Albania. The 9.1 kb - allele is the prevalent allele in the North African (range, 0.53-0.56), Greek (0.51), and Albanian (0.66) populations, whereas the 9.1 kb + allele is most frequent in a mainland Italian town (0.55) and in all Sicilian and Sardinian towns and villages thus far tested, with marked fluctuation ranges of 0.53-0.78 and 0.56-0.80, respectively. In tests for Hardy-Weinberg equilibrium the genotype frequencies observed in Athens and in four of the nine towns in Sicily (but in none of the towns in Sardinia) departed highly significantly from the expected values. Identical results were found in the same towns for a second insertion-deletion polymorphism located on chromosome 22ql13 at a distance compatible with a low incidence of recombination. The data, which are in good agreement with the different histories of the two islands (Sardinia and Sicily), are consistent with a west-east differentiation in Sicily and support the evidence for ancient gene flow from the Iberian peninsula to Sardinia.

Copper, selenium, and zinc concentrations in human milk during the first three weeks of lactation.

Human milk samples were analyzed by neutron activation analysis (NAA) for three essential trace elements (Cu, Se, and Zn). Mothers' milk samples were collected from 25 lactating mothers from the Central Hospital, Tripoli, Libya. The average concentration level of Cu, Se, and Zn declined from 0.84 +/- 0.06 mg/L, 104 +/- 9.46 microg/L, and 16.1 +/- 2.67 mg/L at d 0 to 0.39 +/- 0.045 mg/L, 41.8 +/- 6.66 microg/L, and 4.95 +/- 1.3 mg/L, respectively, at d 20 of lactation. Copper and Zn levels in the Libyan mothers' milk were in agreement with reported levels from other countries, whereas Se was at a higher level. The Cu daily intake level is slightly higher than the RDA (Recommended Daily Allowance) value. Selenium and Zn have higher intake levels than the RDA values but within the tolerable upper intake levels.

Prevalence, species differentiation, haemolytic activity, and antibiotic susceptibility of aeromonads in untreated well water.

The use of untreated water for drinking and other activities have been associated with intestinal and extraintestinal infections in humans due to Aeromonas species. In the present study aeromonads were isolated from 48.7% of 1,000 water samples obtained from wells and other miscellaneous sources. Aeromonas species were detected in 45% of samples tested in spring, 34.5% in summer, 48% in autumn and 60% of samples tested in winter. Speciation of 382 strains resulted in 225 (59%) being A. hydrophila, 103 (27%) A. caviae, 42 (11%) A. sobria and 11 (3%) atypical aeromonads. Of 171 Aeromonas strains tested for their haemolytic activity, 53%, 49%, 40% and 37% were positive in this assay using human, horse, sheep and camel erythrocytes respectively. The results obtained indicate that potentially enteropathogenic Aeromonas species are commonly present in untreated drinking water obtained from wells in Libya (this may also apply to other neighbouring countries) which may pose a health problem to users of such water supplies. In addition, ceftriaxone and ciprofloxacin are suitable drugs that can be used in the treatment of Aeromonas-associated infections, particularly in the immunocompromised, resulting from contact with untreated sources of water.

Ocular fireworks injuries in children.

Fourteen children and six adults presented in 1987 with firework-induced ocular injuries following celebrations of the Prophet Muhammad's birthday in Tripoli, Libya. The children's injuries were, typically, much more severe than those of the adults. Indigenous modifications to the fireworks, which are intended for children's use, render the devices into very dangerous missiles that, in the cases presented, resulted in the loss of one eye and serious damage to another. Educating children of the proper use of legal fireworks, and parents discouraging their children from modifying fireworks should help reduce the incidence of these severe ocular injuries.

Waardenburg syndrome type 2 in an African patient.

A thirty six year-old African man, born in the Southern part of Libya, presented with congenital deafness and white forelock, variable-sized hypopigmented, depigmented patches and hyperpigmented islands within the areas of hypomelanosis affecting the upper parts of the trunk, both arms and forearms. The nasal root was hypertrophied, but there was a lack of lateral displacement of medial canthi. We report this case of Waardenburg syndrome type 2 (WS 2). As no treatment is available for patients with WS 2, prompt diagnosis and referral to a hearing specialist are crucial for the normal development of patients affected with this condition.

[Reasons, circumstances and results of repeat forensic medicine autopsy].

There are only scant literature data on reasons and circumstances of medico-legal second autopsies. The present study includes 12 second autopsies from the period 1992-1997; the first post-mortem examination took place either in the home country (institutes of pathology) or abroad. 7 of the 12 cases of death investigated happened in Germany (exclusively in hospitals) and 5 of them abroad (Netherlands, Romania, Portugal, Libya). Repeat autopsies were ordered by criminal courts (n = 9), private persons (n = 2) and social insurances (n = 1). The main indication was possible medical malpractice (n = 6); acts of violence (n = 3), insurance questions (n = 2) and accidents (n = 1) followed. The time lapse between death and second autopsy was 2-35 days. It was striking, that German institutes of pathology had partially performed autopsies despite the certification of a non-natural death. Clinical autopsies were stopped twice, when evidence of a possible non-natural death occurred. It could be fundamentally stated, that first autopsies in German institutes of pathology had been carefully performed and sufficiently documented. In these cases the second autopsy presented no or only little additional information, as far as the broader taking of (toxicological) samples is not considered. The final medico-legal expertise was then mainly based on the findings of the clinical first autopsy. However, the concurrence of the forensic expert (instead of the clinical pathologist) is undoubtedly essential for the evaluation of these issues involving frequently questions of malpractice. By contrast, the quality of postmortems performed abroad varies widely. 4 of the 5 first autopsies done abroad were regarded as completely or partly insufficient with superficial or almost absent preparation of organs or contradictions in the medical reports, respectively. A repeat autopsy is absolutely necessary in such cases. On the whole, the initial question could be answered in all second autopsies at least in part. This emphasizes the high value of second autopsies and expertises, especially in non-natural cases of death (10 of 12 deaths were finally judged as non-natural).

Y-chromosome DNA haplotypes in north African populations.

The frequency distribution of Y-chromosome haplotypes at DNA polymorphism p49/TaqI was studied in a sample of 505 North Africans from Mauritania, Morocco, Algeria, Tunisia, Libya, and Egypt. A particularly high frequency (55.0%) of Y-haplotype 5 (A2, C0, D0, F1, I1) was observed in these populations, with a relative predominance in those of Berber origin. Examination of the relative frequencies of other haplotypes in these populations, mainly haplotype 4 (the "African" haplotype), haplotype 15 (the "European" haplotype), and haplotypes 7 and 8 (the "Near-East" haplotypes), permit useful comparisons with neighboring peoples living in sub-Saharan Africa, Europe, and the Near East.

[Prevalence of APO e4 allele in Israeli ethnic groups].

The 4 allele of the APOE gene, coding for apo-lipoprotein E, is the most common genetic risk factor for Alzheimer's disease and a significant risk factor for coronary atherosclerosis. There is therefore much interest in studying its frequency in different ethnic groups. We examined its frequency in Jews originating from Libya, Buchara and Ethiopia and in Jews of Sepharadi and Ashkenazi origins. Its frequency among Ethiopian immigrants was 0.27, significantly higher than in the other groups, in which the frequency was between 0.067 and 0.10. These differences in allele frequency may serve as a basis for future studies in Israel to assess the relative contributions of genetic and environmental factors to the incidence of dementia.

[Cholera epidemics in the Ottoman Empire during 1910-1913 and relevant events].

From 1910 to 1913 was one of the disastrous periods of the history of the Ottoman Empire. Cholera epidemic was one of the causes of this calamity. The early cases of cholera were diagnosed on July 15 in Erzurum in 1910. The disease was imported from Russia and started to spread in the country. Cholera appeared in Istanbul on September 1st and spread rapidly. This danger necessitated the mobilization of all civilian and military resources. In spite of these efforts, Istanbul became an important focus of cholera for Turkey, because of intensive human traffic in the capital. Some cholera cases came from Iran to Iraq and from Italy to Libya and disease spread out to the vicinities during this year. This epidemic disappeared in January 1911. According to the official records, between July 15, 1910 and January 12, 1911 cholera killed 4023 people. In May 1911 cholera reappeared in Samsun and spread within the Ottoman Empire and 18876 persons were infected with cholera and 12143 of them died. In 1912 and 1913, the foundations of the Ottoman Empire were shaken by Balkan War, military defeats, lost territory, unlucky refugees and immigrants, and dreadful calamity of cholera epidemic. There is no reliable official record on the exact numbers of cholera patients and deaths. This great epidemic subsided during the Autumn of 1913. In the Ottoman Empire, preparation of Kolle's vaccine against cholera was started in 1912 and its was applied during 1913.
