Dengue is a rapidly spreading mosquito-borne viral disease. During the acute phase of infection, up to 5 days after onset of symptoms, the dengue virus can be detected through NS1 antigen detection, virus isolation, or nucleic acid detection. From 3 days to 2 months after symptoms begin, dengue-specific IgM antibodies are detectable and used for diagnosis. IgG antibodies develop later, after 3 weeks, and can be detected for months or life, indicating a past infection. Differentiating primary from secondary dengue infection involves measuring the ratio of IgM to IgG antibodies. Monitoring of platelet counts and hematocrit values during the acute phase aids diagnosis and assessment of severity.

The 20-year-old male student presented with a week of fever showing a step-ladder pattern, along with mild hepatomegaly. This suggests a provisional diagnosis of enteric fever. Diagnosis can be confirmed through microbiological investigation of blood, bone marrow, blood clots, stool, or urine cultures, which ideally should be done in the first week of illness. Antibiotic susceptibility testing is important as multidrug-resistant strains of Salmonella Typhi have emerged. Prevention emphasizes good sanitation and vaccination.
Typhoid fever is caused by the bacterium Salmonella enterica serovar Typhi. Historically, it was a major cause of death for soldiers during wars due to transmission by flies. Transmission occurs through contaminated food or water by carriers shedding the bacteria in their feces or urine. Prevention includes vaccination, especially for those traveling to or living in endemic areas. Those at highest risk include household members of carriers and clinical lab technicians working with the bacteria.
This document provides information on systemic mucormycosis, including its various clinical manifestations and treatments. It describes pulmonary mucormycosis in the most detail, noting that it is transmitted via inhalation of sporangiospores and invades blood vessels, destroying lung parenchyma. Clinical features include chest pain, dyspnea and hemoptysis. Diagnosis involves chest imaging showing lesions and biopsy of infected tissues. Treatment requires antifungal therapy such as amphotericin B in combination with surgical debridement. The document also briefly outlines other forms of mucormycosis including gastrointestinal, cutaneous, renal and disseminated variants.
Typhoid fever is a severe illness caused by the bacteria Salmonella typhi. It is characterized by prolonged fever and can invade the liver, spleen, and other organs if untreated. It occurs primarily in developing countries with poor sanitation. Persons are infected by consuming food or water contaminated by the feces or urine of infected individuals. Diagnosis involves isolating the bacteria from blood or bone marrow cultures. Antibiotics are the primary treatment and help reduce complications if started early. Vaccines can help prevent infection but hygiene practices are also important for those in endemic areas.
CNS Cryptococcosis is fatal unless treated, with mortality rates of 6-14% despite treatment. Predictors of poor prognosis include high CSF cryptococcal antigen titer, minimal CSF pleocytosis, altered mental status at presentation, positive India ink preparation, and hyponatremia. First line therapy consists of induction therapy with intravenous amphotericin B and fluconazole for 14 days, followed by consolidation therapy with oral fluconazole for 8 weeks and maintenance therapy with fluconazole until CD4 count increases to above 200 for 6 months.
This document discusses disseminated fungal infections, including candidiasis. It notes that fungal infections in hospitals have increased dramatically due to rising immunosuppressed populations. Candida species are the most common cause. Risk factors include ICU stay, immunosuppression, and use of broad-spectrum antibiotics and catheters. Diagnosis relies on blood and tissue cultures but has low sensitivity. Early antifungal treatment improves outcomes, and options include fluconazole, amphotericin B, and echinocandins. Prevention strategies focus on hand hygiene and reducing unnecessary fluconazole use.
Enteric fever, which includes typhoid and paratyphoid fevers, is endemic in India with incidence rates ranging from 102 to 2219 per 100,000 people. The diseases are caused by Salmonella typhi and Salmonella paratyphi which are ingested through contaminated food or water. After penetrating the intestinal wall, the bacteria spread throughout the body via macrophages and cause systemic infection. Common symptoms include sustained fever, abdominal pain, and enlargement of the spleen and liver. Diagnosis involves blood, bone marrow or stool cultures. Ceftriaxone is frequently used for treatment and typically leads to defervescence within 4-5 days.
Salmonella enterica serovar Typhi causes enteric fever or typhoid fever in children. It is transmitted through ingestion of contaminated food or water. In the body, it invades the intestinal mucosa and spreads to the bloodstream and reticuloendothelial system. Clinical features include sustained high fever, abdominal discomfort, diarrhea, and complications affecting the nervous, cardiovascular or pulmonary systems. Diagnosis involves blood or stool cultures. Treatment recommended is with third generation cephalosporins like cefixime or ceftriaxone. Vaccines provide protection, especially the Vi conjugate vaccine for younger children.
The document discusses invasive fungal infections in critically ill patients. It notes that these infections have increased due to factors like immunosuppression from medical therapies. Common fungal pathogens include Candida species and Aspergillus. Diagnosis can be challenging as cultures often have low sensitivity. Biomarkers like galactomannan and beta-D-glucan can help but have limitations. Early treatment with antifungals is important to reduce mortality, though choice of agent depends on individual patient and infecting organism factors. Fungal infections should be considered in critically ill patients with persistent fever despite antibiotics.

This document discusses pyrexia of unknown origin (PUO), defined as a fever without an obvious source based on clinical examination. It provides details on age groups for PUO, including neonates less than 28 days who should be hospitalized due to high risk of serious bacterial infection. For infants 1-3 months, certain criteria like appearance, white blood cell count and urine analysis determine if further investigation and treatment is needed. Causes of PUO are discussed, with the most common being a common disease presenting atypically. Management involves investigation and potential antibiotic treatment depending on age and symptoms.
The document summarizes current methods for diagnosing dengue virus infection. It discusses the limitations of clinical diagnosis due to non-specific symptoms in early infection. Laboratory diagnostic methods include virus isolation through mosquito inoculation or cell culture, which is sensitive but requires specialized facilities. Reverse-transcriptase PCR detection of viral RNA in blood is now more widely used, as it is rapid, sensitive and specific. Both virus isolation and PCR can detect infection early in the viremic phase. Serological tests detect antibody response and are more useful later in infection or for secondary dengue diagnosis. Improved early diagnosis remains a challenge, especially with development of a dengue vaccine.

Myocarditis is defined as inflammation of the myocardium that is characterized by inflammatory cell infiltrates and myocyte degeneration or necrosis. It is most often caused by viruses, which can damage the myocardium in three phases: acute viral replication, autoimmune injury, and a chronic dilated cardiomyopathy phase. Symptoms range from being asymptomatic to acute cardiogenic shock and sudden death, and may include fever, respiratory distress, chest discomfort, and signs of heart failure. Diagnosis involves electrocardiogram changes, chest x-ray showing cardiomegaly, echocardiogram demonstrating reduced systolic function, and endomyocardial biopsy identifying inflammation. Treatment is supportive with medications like ACE inhibitors, beta-blockers

Solid organ transplant recipients have a higher risk of developing TB compared to the general population. The majority of post-transplant TB cases are due to reactivation of latent TB infections in recipients. Donor-derived TB may occur if the donor was from a TB endemic area or had untreated TB. For living donors, a TST or IGRA is used for screening and treatment of latent TB is considered. For recipients, treatment of latent TB is indicated if they have a risk factor such as a positive PPD or history of TB exposure. Recommended regimens include 9 months of INH or 4 months of rifampin plus other drugs. Treatment duration of at least 12 months is important to prevent TB recurrence.
Treatment of HCV in HIV-infected patients has historically been challenging with low response rates and side effects.

HIV infection is caused by a retrovirus that can lead to AIDS if not treated. It is transmitted through bodily fluids and can be diagnosed through viral load tests, p24 antigen tests, HIV antibody tests, and Western blot. If left untreated, it progresses from acute infection to asymptomatic infection and eventually symptomatic infection and AIDS. Antiretroviral therapy is recommended for all infected individuals to suppress the virus and preserve immune function. The goals of treatment are to durably suppress the virus, restore immune function, and prevent transmission. Response is monitored through clinical, virologic, and immunologic measures.
This document discusses HIV infection in pregnancy and strategies to reduce mother-to-child transmission of HIV. It covers antepartum, intrapartum, and postpartum care for HIV-infected women including antiretroviral regimens, monitoring, testing protocols, and delivery methods. The goal is to reduce the risk of perinatal HIV transmission to less than 2% through highly effective antiretroviral therapy, elective cesarean section when appropriate, and avoiding breastfeeding.
A HIV-infected patient presents with cough, fever and sputum production for 4 days. A chest X-ray shows a left lower lobe infiltrate and the patient has a low CD4 count of 150/mm3.

PCP is a common opportunistic infection in patients with advanced HIV/AIDS. Diagnosis requires staining of respiratory samples for visualization of the organism, with BAL having the highest diagnostic yield. Treatment involves anti-pneumocystis medications.
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.

28. SALMONELLA DIAGNOSIS
• Other than a positive culture, no specific laboratory test is diagnostic for enteric fever.
• The definitive diagnosis of enteric fever requires the isolation of S. typhi or S.
paratyphi from blood, bone marrow, other sterile sites, rose spots, stool, or intestinal
secretions.
• The sensitivity of blood culture is only 40–80%,.
• Bone marrow culture is 55–90% sensitive, and, unlike that of blood culture, its yield is not
reduced by up to 5 days of prior antibiotic therapy.
• Stool cultures, while negative in 60–70% of cases during the first week, can become
positive during the third week of infection in untreated patients.
• Several serologic tests, including the classic Widal test for “febrile agglutinins,”
are available. None of these tests is sufficiently sensitive or specific to replace culture-
basedmethods
• PCR and DNA probe assays to detect S. typhi in blood have been identified but have not
yet been developed for clinical use.
31. • A 22-year old female medical student who
visited Sudan few months back, presents with
a history of haematuria. On investigation
schistosomal serology is shown to be
positive.
• Select the treatment of choice:
• a) Albendazole
• b) Ivermectin
• c) Mebendazole
• d) Praziquantel
37. Mycobacterium marinum
• AFB+ ,Fast growing
• Most strains of M marinum
have been found to be
resistant to the
antituberculosis medications
isoniazid, streptomycin,
• . The organism is sensitive to
rifampin plus ethambutol,
tetracyclines, trimethoprim-
sulfamethoxazole (TMP-
SMZ), clarithromycin, and
fluoroquinolones.
38. • The day after hunting and skinning wild rabbits, a hunter develops an
inflamed papule on one finger.The papule rapidly enlarges and then bursts,
releasing pus and forming a clean ulcer cavity productive of thin, colorless
exudate (see image). Several days later, the patient develops severe illness
with atypical pneumonia and delirium. It is at this point that the patient
seeks medical care.
• The regional lymph nodes of the axilla of the affected arm are enlarged.
Reduced breath sounds and occasional rales are heard. Splenomegaly is
noted. Blood studies show a mild leukocytosis.
• Which of the following is the most likely diagnosis?
• a) Actinomycosis
• b) Brucellosis
• c) Melioidosis
• d) Plague

39.
40. Tularemia
• Caused by Francisella tularensis
• F. tularensis—a small (0.2 m by 0.2–0.7
m), gram-negative, pleomorphic,
nonmotile, non-spore-forming bacillus.
• Transmission by biting or blood-sucking
insects, contact with wild or domestic
animals, ingestion of contaminated water
or food, or inhalation of infective aerosols.
• An incubation period of 2–10 days
• fever, chills, headache, generalized
myalgias and arthralgias, lymphadenopathy
(Epitrochlear lymphadenopathy)
41. Tularemia
• In ulceroglandular tularemia, the ulcer is
erythematous, indurated, and nonhealing,
with a punched-out appearance that lasts
1–3 weeks. The papule may begin as an
erythematous lesion that is tender or
pruritic; it evolves over several days into
an ulcer with sharply demarcated edges
and a yellow exudate
• Direct microscopic, indirect fluorescent
antibody test but false-positive results due
to Legionella ,PCR and culture.
• Tularemia is most frequently confirmed by
agglutination testing.
• Steptomycin , cipro , gent 10 days
