In sub-Saharan Africa, there is a high burden of paediatric surgical conditions and a paucity of data regarding outcomes of congenital colorectal anomalies. A retrospective, descriptive analysis utilizing the Kamuzu Central Hospital (Lilongwe, Malawi) paediatric acute care surgery database (age ≤ 18 years) over 44 months was performed. Of the 133 children presenting, 82 had Hirschsprung disease (HD) (2.4 ± 2.7 years) and 51 had anorectal malformations (ARM) (1.8 ± 2.4 years). Of the latter, 51.0% underwent surgery, mainly exploratory laparotomy (n = 15, 57.7%) and posterior sagittal anorectoplasty (n = 7, 26.9%). Of those with HD, 50.0% underwent operative intervention (77.3% boys), including exploratory laparotomy (n = 17, 41.5%) and definitive pull-through (n = 8, 19.5%). A dearth of expert paediatric surgeons and limited exposure to paediatric conditions in general surgeons limits definitive surgery. An emphasis on paediatric surgical training and improvement of referral networks for definitive therapy will improve patient outcomes.

This retrospective cohort study was aimed at evaluating the factors associated with the resumption of sexual intercourse (SI) before the six-week postpartum visit and was carried out between 1 January and 15 February 2014. The main variables studied included maternal age, number of living children, mode of delivery, complications observed at delivery and resumption or not of SI. Data from women who resumed SI were compared to those of women who did not. Fisher’s exact test and t-test were used for comparison. We recruited 120 women, among whom 95 (79.1%) resumed SI. Of these, 65/95 (68.4%) did not attend the postpartum visit while 30 (31.6%) did (P = 0.321). The factors associated with early resumption of SI were maternal age of 20–34 years (P < 0.001), women with one child (P < 0.004) and who had had an uncomplicated vaginal delivery (P < 0.001). Our conclusion is that nursing mothers should receive postpartum contraception before leaving the hospital.

Tularaemia has become a public health threat in Turkey. Our aim was to examine the epidemiological characteristics of 154 tularaemia cases reported from Kayseri, Central Anatolia, between 2010 and 2017. Clinical diagnosis was confirmed by micro-agglutination test (≥1/160 titres). Most patients (56.5%) were residing in rural areas. The year with the highest case load was 2011 (40% of all cases). Tularaemia was reported in all seasons, but mostly in February (26.1%). Morbidity rates were higher in women and people aged ≥65 years. The tularaemia incidence in Kayseri was higher than in the whole country between 2011 and 2016, though after the initial outbreak between 2010 and 2012, it seems to have become less frequent.

Postscabies prurigo (PSP) is caused by a delayed hypersensitivity reaction to antigens of the mite. Treatment is based on potent topical or intralesional corticosteroids. We present the results of a study on the effectiveness of a topical combination of diflucortolone and chlorquinaldol. Eighteen African patients who had been previously affected by scabies and treated with permethrin were enrolled. The diagnosis of PSP was made by excluding other causes through microscopic examinations. All patients were treated with the drug combination by two applications daily for two weeks. The primary study objective was to evaluate the itch by a visual analogue scale (VAS) of 0–100. Fifteen patients (83.3%) could be evaluated. All reported improvements: from 86/100 at the start to 29/100 (−57/100) at the end of treatment. Chlorquinaldol, known as an antiseptic agent, demonstrated, according to results of this study, an important anti-itch action.

The course of acute hepatitis A (AHA) in childhood is most often benign. There are relatively few reports of gallbladder involvement during such infection and its consequences. We discuss the cases of 75 children (mean age = 4.5 years) with confirmed AHA. Clinical and laboratory evaluation upon admission were classical for AHA. Only two children had normal bilirubin levels and 38.7% had visible involvement of the gallbladder with wall thickening of >3 mm, while six met criteria for acute acalculous cholecystitis. There appears to be no clear relationship between thickening of the gallbladder wall and transaminase levels, but a significant relationship with total and direct bilirubin levels (P < 0.05). Ultrasonographic examination should therefore be carried out in each case of AHA and follow-up should be performed with greater caution, if there are changes in the gallbladder wall.

Despite efforts to limit the morbidity and mortality from tuberculosis (TB), it continues to be an important cause of death. There is an urgent need for a diagnostic test that accurately and quickly diagnoses TB, especially if it is also a near-point-of-care test. The GeneXpert polymerase chain reaction test (known in India as CBNAAT [cartridge-based nucleic acid amplification test] and is capable of diagnosing TB and rifampicin resistance within 2 h) is a promising tool.

The duration of our study was two years and was carried out in the DOTS centre of a tertiary care hospital in India. A total of 5449 samples were processed using CBNAAT. Of the total samples tested, 2068 were extra-pulmonary. The following information was collected: number of extra-pulmonary samples processed; number of Mycobacterium tuberculosis (M. tuberculosis)-positive samples; patterns of rifampicin sensitivity; number of people living with HIV (PLHIV); and number of children.

Of the samples, 62.1% were from suspected pulmonary TB patients. Out of the total samples tested using CBNAAT, 21.8% were positive for M. tuberculosis. Rifampicin resistance was seen in 9.2%, 8.5% and 10.3% of the total, pulmonary and extra-pulmonary samples, respectively, in M. tuberculosis-positive samples. Overall, 36.9% samples were from the paediatric population and 5.7% belonged to PLHIV. Rifampicin resistance was seen in 8.8% and 8.3% of the M. tuberculosis-positive paediatric and PLHIV samples, respectively.

Chronic hepatitis C (HCV) patients commonly have insulin resistance which is a risk factor for disease progression. Oesophageal varices may bleed with high mortality. We aimed to assess the relationship between insulin resistance and oesophageal varices. HCV-related compensated liver cirrhosis patients (n = 146) underwent gastroscopy and homeostasis model assessment (HOMA)-IR, HOMA-β and HOMA-S calculations. Their average age was 54.98 years; most (84.9%) patients were men and non-diabetic (60.3%). Patients with oesophageal varices had higher median Model for End-Stage Liver Disease (MELD) scores and comparable Child-Pugh class. Patients with and without oesophageal varices had comparable (P > 0.05) HOMA scores and insulin resistance percentage of 82.9% versus 85.5%. We therefore conclude that insulin resistance is unrelated to the presence of oesophageal varices.

In Bihar, an estimated 4500 snakebite deaths occur per year, but community data are scarce. Using a multi-stage cluster design, 4159 households were interviewed across six Community Development (CD) blocks in North Bihar, identifying 206 snakebites and 254 deaths between the Chhaat festivals of 2014 and 2015. Concurrently, 357 snakebite victims presented to Duncan Hospital from this area. None of the 254 verbal autopsies were attributed to snakebite envenoming. The annual community snakebite incidence was 643/100,000 person-years (95% confidence interval [CI] = 556–730) with peak incidence in women aged 30–39 years at 1323/100,000 person-years (95% CI = 837–1809). Two-thirds of snakebite victims attended traditional healers first for help (95% CI = 59.9–73.2). The community envenomation rate was 24.9/100,000 person-years (95% CI = 7.6–42.2). The hospital envenomation rate was 4.6% (95% CI = 3.5–5.7). Of the hospital snakebite deaths, 91% (10/11) were aged <16 years. Only 4.6% (95% CI = 4.1–5.1) of snakebite victims from this area presented at the local hospital.

Glucocorticoids are first-line therapy for children with idiopathic nephrotic syndrome (INS). These children are at risk of deranged bone metabolism and low bone mineral density (BMD). We studied 60 children with INS and divided them into two groups. Group 1 included 21 children (initial and infrequent relapsing) and group 2 included 39 children (frequent relapsing, steroid dependent and steroid resistant). Dual-energy X-ray absorptiometry of the lumbar spine was performed to assess BMD. Mean BMD Z-score was compared in both groups; this correlated significantly on univariate analysis with cumulative steroid dose, serum vitamin D levels and calcium supplementation. However, on multivariate analysis, serum vitamin D level was the only factor significantly predictive of low z-score.

Community mobilisation is an essential part of cervical cancer screening programmes to increase demand for screening services. While there are different methods of community mobilisation, in Ethiopia community conversations during traditional coffee ceremonies appear to be a context appropriate and effective method. Linkage of community mobilisation with existing community networks can increase uptake of cervical cancer screening and improve continuous support and care among community members.

Rabies has two distinct clinical syndromes, encephalitic (or ‘furious’) and paralytic (or ‘dumb’). The paralytic form presents as acute flaccid myelitis and is more common in patients who received post-exposure anti-rabies vaccination without rabies immunoglobulins. We have recently had the opportunity to manage a middle-aged man presenting as ‘dumb’ paralytic rabies.

Diffuse cutaneous leishmaniasis is a rare chronic infectious disease, associated with Leishmania mexicana and L. amazonensis, presenting as multiple non-ulcerative painless nodules, with a tendency to relapse soon after treatment. We report a case of a 56-year-old Mexican woman exhibiting nodular lesions, plaques, crusts and scars involving the whole body. A solitary nodule was present at the junction between hard and soft palates. Diffuse cutaneous leishmaniasis is a disfiguring disease resulting in severe scarring if untreated.

Cutaneous chrysosporium infection is extremely rare and underdiagnosed. We present an immunocompromised patient who presented with recurrent cutaneous abscesses. Histopathology of the abscess showed thick-walled conidia and septate fungal hyphae within the subcutis and fungal culture grew Chrysosporium species.

Libman-Sacks endocarditis (LSE) is one of the most characteristic cardiac lesions in systemic lupus erythematosus (SLE). Patients may remain asymptomatic, while symptomatic patients often suffer with systemic emboli. These commonly test positive for anti-phospholipid antibody (aPA). The association of LSE with an overlap of rheumatoid arthritis (RA) and lupus (also known as ‘rhupus’) is rare. We report such a patient, who had been diagnosed as having RA seven years before and had suffered an acute ischaemic stroke one year previously and had echocardiographic evidence of LSE found during routine evaluation. However, she tested negative for aPA.

Iatrogenic diaphragmatic hernia is rare in children and we report a preterm low birth weight neonate with a presumably acquired diaphragmatic hernia due to trauma caused by treatment following pneumothorax.

Scrub typhus, a re-emerging acute febrile zoonosis can present as an undifferentiated fever often complicated by potentially fatal systemic involvement. Acute pancreatitis is a rare complication of scrub typhus which can result in a marked elevation of serum lipase. We report three cases of scrub typhus who presented with acute undifferentiated fever, where a marked elevation of serum lipase occurred without any evidence of acute pancreatitis, or other causes of elevated lipase levels. Scrub typhus should be considered as a cause of marked elevation of serum lipase, which can occur in the absence of pancreatitis.

Mucocoeles are slow-growing, locally aggressive, mucus-containing cysts, lined by epithelium, which, when infected, are called pyomucocoeles. We present the case of a five-year-old girl who presented with a frontal pyomucocoele requiring decompression and adequate antibiotics.

Mucormycosis is generally considered to be an acute, rapidly progressing, opportunistic fungal infection. Chronic manifestations are extremely rare. Mucormycosis affecting the jejunum is very rare and few cases have been reported. We report a case of mucormycosis causing jejunal stricture in an infant aged six months.

Liver abscesses, either pyogenic or amoebic, with or without the involvement of the pleura, are not infrequently encountered in children. Isolated tubercular liver abscess without active pulmonary, gastrointestinal or other clinical evidence of tuberculosis is, however, rare and more so its rupture into the pleura. We report a case of a 14-year-old girl who presented with a liver abscess rupturing into the pleura causing an empyema. Successful management was achieved by intercostal tube drainage and antitubercular treatment.
