A structured questionnaire was administered to 50 medical patients, 50 surgical patients and 50 staff members at Vila Central Hospital, Vanuatu. A similar study was conducted 10 years earlier. In the intervening decade, Vanuatu has seen unprecedented population growth, increasing expatriate numbers, and the introduction of mobile phone and Internet networks. Given these social transformations, this study aimed to identify changes in custom medicine use over this period. Fifty-nine percent of interviewees had used custom medicine at least once, compared to 86% reported in the 2003 study. Thirty-two percent had used custom medicine in the last 12 months, a significant decline from 60% in the previous study. Collectively, rates of custom medicine use have declined but especially in the physical therapies such as bone setting. We believe this declining custom medicine use reflects an overall weakening traditional culture within Vanuatu and believe that within a generation, custom medicine knowledge will likely be lost.

Scrub typhus is an important cause of acute febrile illness. This observational study describes the clinical features and complications of the patients diagnosed to have scrub typhus in Christian Medical College & Hospital, Ludhiana, Punjab, India. The diagnosis of scrub typhus was made by using Bioline SD Tsutsugamushi test kit which detects IgM, IgG or IgA antibodies to Orientia tsutsugamushi. Sixty-two patients of scrub typhus were seen during the study period of 1 year. The mean age of the study group was 39.9 years. All the patients presented with fever, and of these 31 (50%) had non-specific symptoms. All others had some complication, namely ARDS/ALI in 18 (29%), neurological involvement in 12 (19.4%), acute kidney injury (AKI) in 16 (25.8%), hypotension in eight (12.9%), thrombocytopenia in 23 (37.1%), hepatitis in 34 (54.8%) and MODS in 19 (30.7%). Eschar was present only in nine patients. Three patients expired due to multi-organ failure, hypotension and metabolic acidosis.

Scrub typhus is re-emerging in India. We describe an outbreak of 45 cases from our tertiary care center in north India. This outbreak included city dwellers who had no history of travel to hilly areas. The classical feature of scrub typhus, the eschar, was also noted rarely in these patients. The changing epidemiology of scrub typhus should be kept in mind while attending patients with acute febrile illness.

Scrub typhus is an acute febrile illness caused by a tick bite infected with the bacteria Orientia tsutsugamushi. The clinical diagnosis is difficult as the symptoms are similar to other febrile illnesses such as dengue, typhoid, leptospirosis and so on. An eschar, if present, will narrow down the provisional diagnosis towards scrub typhus. There are no data on the preferential sites of tick bites in an Indian population. We present here the preferential sites of tick bites in a South Indian population of 123 cases positive for eschar. Geographically, clothing styles vary leading to the differences in the areas of skin exposed to the bite and thus the formation of eschars. Scrub typhus, if not treated, may lead to fatal complications. As scrub typhus is one of the most under-reported illnesses in the world, clinicians should look for the presence of an eschar in the preferential sites at least to narrow down the diagnosis and treatment.

Tetanus is a life-threatening, preventable infection with a high mortality. Our aim was to determine the changes in incidence and case fatality rate at Sengerema Designated District Hospital in a retrospective review of patients who had been hospitalised with tetanus between 1962 and 2012. In the 1970s and 1980s a vaccination campaign was organised in order to cover the whole district and to provide immunity for tetanus. Data are based on 476 cases with a fatal outcome in 305 cases. The case fatality rate has declined from 74% between 1982 and 1991 to 11.1% currently. Improved facilities are required in order to significantly reduce adverse outcome from tetanus.

The epiphyseal perichondrium is calcified during the rachitic healing process and visible radiologically as ‘a head within a head’ around the proximal femoral epiphysis in young children. Seen in isolation, these radiographs can pose diagnostic dilemmas.

We retrospectively documented indications for Caesarean sections in a rural district level hospital in the highlands of Papua New Guinea. Over a 53-month study period, 745 Caesarean sections were performed. Prolonged labour, previous history of Caesarean section, cephalopelvic disproportion, malpresentation and fetal distress accounted for over 88% of Caesarean sections performed. In older mothers (aged >30 years), antepartum haemorrhage (Fisher exact test, P = 0.05) and multiple indications (P = 0.001) were leading reasons for Caesarean sections while cephalopelvic disproportion (P = 0.005) was the leading indication in younger mothers. Further prospective studies incorporating perinatal and maternal mortality rates are required to optimise the value of Caesarean sections at district level hospitals in Papua New Guinea.

Ectopic pregnancy is a common gynaecological emergency in Nigeria, West Africa. Here we present a case that brings to light some of the problems facing the health sector in reducing the high maternal mortality rate.

We present a case of spontaneous antepartum uterine rupture through a previous lower segment Caesarean section (LSCS) scar with clinical features mimicking an advanced extrauterine pregnancy (AEUP) in a twin pregnancy at 28 weeks gestation. This report illustrates the need to consider a diagnosis of a ruptured uterus in any patient with a previous abdominal delivery who presents with mild abdominal tenderness and an ultrasonographic image suggestive of demised fetus in the intra-peritoneal cavity.

Meningitis following lumbar puncture and spinal anaesthesia is a rare but serious complication. A 19-year-old woman was administered spinal anaesthesia at another centre prior to a Caesarean section. The following day she experienced headaches. On the fourth day, she started vomiting and having convulsions, and became agitated. Meningitis was diagnosed based on a clinical examination and analysis of a lumbar puncture sample. After 21 days of treatment, she was discharged.

Meningitis should be considered in the differential diagnosis of a patient presenting with headaches following spinal anaesthesia. The causes of meningitis following spinal anaesthesia are debated, and it is difficult to distinguish between aseptic and bacterial meningitis. It should be compulsory to wear a face mask while performing a dural puncture.

In dengue endemic regions, a chief complaint of nocturnal fever often is a pathognomic phrase that triggers an investigation for dengue. This article looks at cases of patients who were tested for dengue based on their symptoms of weakness and loss of appetite, without fever as fever was absent in most cases. The article also examines the changes in weight that occur after diagnosis of dengue and compares it to weight loss (if any) that occurred prior to the diagnosis. Dealing with the anorexia and weight loss is challenging for physicians, patients and family members.

Severe ulcerative colitis can be associated with bowel perforation. Bowel perforation rarely leads on to abdominal wall and scrotal wall emphysema. Bowel perforation in such cases can be spontaneous or iatrogenic (colonoscopy-related). We report a rare scenario where a patient presented with abdominal wall and scrotal emphysema after topical corticosteroid enema-induced traumatic rectal perforation. Topical corticosteroids were stopped immediately after identification of rectal perforation. The patient was managed conservatively with intravenous antibiotics. With this report we intend to sensitise clinicians and topical enema manufacturers regarding this rare complication.
